11.3 Force Majeure. Neither Party shall be liable for non-performance or delay in performance caused by an Event of Force Majeure. The non-performing Party shall notify the other Party of such event of Force Majeure within seven (7) days 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 suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use, throughout the period of suspension of performance, commercially reasonable efforts to remedy its inability to perform; provided, however, that in the event the suspension of performance continues for ten (10) days after the date such Force Majeure commences, the Parties shall meet to discuss in good faith how to proceed in order to carry out the intent of this Agreement. For purpose of this Agreement a Force Majeure shall not include: (i) a Party’s failure to commit sufficient resources, financial or otherwise, to its activities under this Agreement, or (ii) general market or economic conditions.

11.4 Assignment. Neither Party may assign this Agreement in whole or part without the other Party’s prior written consent; any attempted or purported assignment without that consent shall be void.

11.5 Severability: No Waiver. A finding that a provision of this Agreement is invalid shall not affect the validity of this Agreement’s other provisions, which shall remain in effect. The Parties will replace the invalid provision with a valid provision that best accomplishes the Parties’ original intent. A Party’s failure or omission to invoke a right under this Agreement in connection with an event or occurrence shall not be a waiver or affect the Party’s ability to assert that right for future events or occurrences.

11.6 Governing Law and Dispute Resolution. The laws of the State of Delaware, USA shall govern this Agreement and its construction. The Parties expressly disclaim the applicability of the International Convention on the Sale of Goods to this Agreement, and it shall not apply to this Agreement. The Parties will resolve any dispute, controversy or claim arising out of or relating to the validity, formation, enforceability, performance, breach or termination of this Agreement (“Dispute”) in accordance with this Section 11.6, with the resolution commencing by a Party notifying the other Party in writing of any Dispute it intends to so resolve. The Parties will attempt to resolve any Dispute amicably through good faith discussions between an appropriate CAMBER associate or more senior officer and a senior executive of KADMON.

11.7 Entire Agreement and Amendments. This Agreement represents the Parties’ entire agreement on this subject matter and supersedes any prior agreements. This Agreement

may be amended only by a writing signed and delivered by the Parties’ authorized representatives.
