hand, and Vyera, on the other hand, shall be independent contractors and that the relationship between the two Parties shall not constitute a partnership, joint venture or agency, including for tax purposes. Neither CytoDyn nor Vyera shall have the authority to make any statements, representations or commitments of any kind, or to take any action which shall be binding on the other, without the prior written consent of the other Party to do so. All persons employed by a Party shall be employees of that Party and not of the other Party and all costs and obligations incurred by reason of such employment shall be at the expense of such Party. 14.5 Force Majeure. Both Parties shall be excused from the performance of their obligations under this Agreement to the extent that such performance is prevented by Force Majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting Force Majeure continues and the nonperforming Party takes reasonable efforts to remove the condition. Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a Force Majeure affecting such Party. If a Force Majeure persists for more than [***], then the Parties shall discuss in good faith the modification of the Parties' obligations under this Agreement in order to mitigate the delays caused by such Force Majeure. Source: CYTODYN INC., 10-Q, 1/9/2020 14.6 Assignment. Vyera may not assign this Agreement, or any rights or obligations hereunder without the prior written consent of CytoDyn, not to be unreasonably withheld or delayed provided that Vyera may assign this Agreement without CytoDyn's consent to an Affiliate or to a successor to substantially all of the business of Vyera to which this Agreement relates. A Change of Control shall be deemed an assignment for purposes of this Agreement. Any permitted successor or assignee of rights and/or obligations permitted hereunder shall, in writing to the other Party, expressly assume performance of such rights and/or obligations. Any permitted assignment shall be binding on the successors of the assigning Party. Any assignment or attempted assignment by Vyera in violation of the terms of this Section 14.6 shall be null, void and of no legal effect. For clarity, nothing in this Agreement shall prohibit Vyera from undergoing any Change of Control, but if Vyera undergoes a Change of Control, it will be subject to Section 2.6. CytoDyn may assign this Agreement and its rights and obligations hereunder, in whole but not in part, to any Third Party not in a materially worse (financially and otherwise) of performing CytoDyn's obligations hereunder without the prior written consent of Vyera (it being understood that any other assignment of this Agreement or any rights or obligations hereunder shall require the prior written consent of Vyera, not to be unreasonably withheld or delayed). 14.7 Severability. If any one (1) or more of the provisions of this Agreement is held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, the provision(s) shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable provision such that the objectives contemplated by the Parties when entering this Agreement may be realized. 14.8 Waiver and Non-Exclusion of Remedies. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. The waiver by either Party hereto of any right hereunder or of the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach or failure by such other Party whether of a similar nature or otherwise. The rights and remedies provided herein are cumulative and do not exclude any other right or remedy provided by Applicable Law or otherwise available except as expressly set forth herein. 14.9 Further Assurance. Each Party shall duly execute and deliver, or cause to be duly executed and delivered, such further instruments and do and cause to be done such further acts and things, including the filing of such assignments,
