average sale price of the other product(s) when sold separately in finished form and C is the weighted average sale price of the Combination Product.

Agreement. Such consultation will begin immediately after one Party has delivered to the other Party a request for consultation. If the dispute cannot be resolved within [***] following the date on which the request for consultation is delivered,
then either Party may submit the dispute to be finally settled by arbitration administered in accordance with the procedural rules of the International Court of Arbitration of the International Chamber of Commerce (the “ICC”) in
effect at the time of submission. The arbitration will be governed by the laws of the State of New York, USA. The place of arbitration will be New York. The official language of the arbitration will be English. The tribunal will consist of one
arbitrator to be appointed by the ICC. The arbitration proceedings will be confidential, and the arbitrator may issue appropriate protective orders to safeguard each Party’s Confidential Information. During the course of arbitration, the
Parties shall continue to implement the terms of this Agreement. The arbitral award will be final and binding upon the Parties, and the Party to the award may apply to a court of competent jurisdiction for enforcement of the award. Notwithstanding
the foregoing, each Party has the right to institute an action in a court of proper jurisdiction in the United States for injunctive or other equitable relief pending a final decision by the arbitrator.

Agreement contains the entire agreement between the Parties with respect to the subject matter of this Agreement. Prior agreements are hereby superseded. For the avoidance of doubt, this Agreement shall supersede that certain Confidentiality
Agreement, dated as of [***]; provided, however, that all “Confidential Information” disclosed or received by the Parties thereunder will be deemed “Confidential Information” hereunder and will be subject to the terms and
conditions of this Agreement. Each Party disclaims that it is relying on any representations or warranties other than those set forth in this Agreement, and irrevocably waives any rights that it might otherwise have to extra-contractual remedies,

14.11 Severability. If any provision in this Agreement is held to be invalid, illegal or unenforceable in any respect, then (a) the
provision will be replaced by a valid and enforceable provision that achieves as far as possible the intention of the Parties and (b) all other provisions of this Agreement will remain in full force and effect as if the original agreement had
been executed without the invalidated, illegal or unenforceable provision.

one or more counterparts, each of which will be deemed an original, but all of which together constitute one and the same instrument. Executed counterparts may be exchanged by facsimile or e-mail in PDF or
