The Defending Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Other Party, which shall not be unreasonably withheld.

If, in the performance of this Agreement, one of the Parties is prevented, hindered or delayed by reason of any cause beyond such Party’s reasonable control (e.g., war, riots, fire, strike, epidemics, pandemics, acts of terror, governmental laws), such Party shall be excused from performance to the extent that it is necessarily prevented, hindered or delayed (“Force Majeure”). The non-performing Party shall notify the other Party of such Force Majeure within [***] after such occurrence by giving written notice to the other Party stating the nature of the event, its anticipated duration, and any action being taken to avoid or minimize its effect.

The waiver by either Party 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 said other Party whether of a similar nature or otherwise.

If Company undergoes a Change of Control in which the acquiring party owns or controls a competing PD-1 Antagonist, then upon MSD’s request, the Parties and the acquiring party shall engage in good faith discussion and shall adopt reasonable procedures to be agreed by MSD to prevent the disclosure of Sensitive Information beyond Company’s personnel having access to or knowledge of Sensitive Information prior to the Change of Control and other personnel of the Change of Control partner approved by MSD, and to control the dissemination of Sensitive Information disclosed after the Change of Control to prevent the use of Sensitive Information for the development or commercialization of competing PD-1 Antagonist products. Such procedures shall include provisions allowing designated management personnel to review and evaluate on a comparative basis business and technical plans and information regarding the Combination, the MSD Compound, and competing PD-1 Antagonist products, in connection with portfolio decision-making (but not, for clarity, for use in development or commercialization of competing PD-1 Antagonist products).
