ARTICLE 9 INTELLECTUAL PROPERTY RIGHTS 9.1 Manufacturing License Grant. Subject to the terms herein, MediWound hereby grants to Vericel a non-exclusive, sublicensable (subject to Section 4.2 of the License Agreement) license under the MediWound Technology and MediWound's interest in the Joint Technology, to Manufacture and have Manufactured Licensed Products in the Territory for use in the Field in the Territory. 9.2 Trademarks License Grant. MediWound hereby grants to Vericel an exclusive (even as to MediWound), sublicensable, royalty- free, fully paid-up, license in the Territory to use the Licensed Trademarks (as defined in the License Agreement) and a non- exclusive, sublicensable, royalty-free, fully paid-up, license to use the MediWound name and trademark, in 25 9012190/26 each case, in connection with the Manufacture of Licensed Products in or for the Territory. All uses of the Licensed Trademarks by Vericel (and its Affiliates, Sublicensees and Distributors) in connection with the Manufacture of Licensed Products in or for the Territory shall be in accordance with Regulatory Approvals and all applicable Laws and MediWound's quality control guidelines for the Licensed Trademarks, as may be amended from time to time. Vericel (and its Affiliates) shall only use the Licensed Trademarks licensed hereunder in connection with the Manufacture of Licensed Products in the Territory. Vericel shall not (and shall cause its Affiliates, Sublicensee and Distributors not to) use such Licensed Trademarks to identify, or in connection with the marketing of, any other products. 9.1 Ownership. Ownership of all inventions and discoveries made by the Parties in the course of Manufacturing and supply of the Product hereunder (including Manufacture and supply of Product) shall be determined in accordance with the terms of the License Agreement. ARTICLE 10 FORCE MAJEURE 10.1 Excusing Performance. Neither Party shall be liable for the failure to perform its obligations under this Agreement to the extent such failure is due to events beyond the reasonable control of the non-performing Party, including fires, floods, earthquakes, hurricanes, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorist acts, insurrections, riots, civil commotion, strikes, lockouts or other labor disturbances involving the workforce of any Third Party, or acts of God (a "Force Majeure Event"). Notwithstanding anything to the contrary herein, the occurrence of a Force Majeure Event will not excuse or prevent a failure of MediWound to deliver Product from being deemed a "Supply Failure" or otherwise limit Vericel's rights, to the extent applicable, under Section 2.13. 10.2 Notice of Force Majeure Event. A Party claiming a right to be excused from performance under Section 10.1 shall immediately notify the other Party in writing of the extent of its inability to perform, which notice shall specify the Force Majeure Event and the estimated likely period of time during which its performance will be affected. 10.3 Resumption; Termination. A non-performing Party as a result of a Force Majeure Event shall use reasonable best efforts, at its own expense, to eliminate the Force Majeure Event and to mitigate the effect of such cause and resume performance under this Agreement, in each case, as soon as practicable and for as long as such Force Majeure Event continues. Further, consistent with diligent risk management practices, MediWound will keep current a risk management program. If MediWound is affected by any Force Majeure Event, MediWound agrees to perform its obligations under this Section 10.3 to mitigate the effect thereof and resume performance under this Agreement in the same manner as MediWound would use to resolve any similar disruptions affecting its own products (including EscharEx). MediWound shall use reasonable best efforts to ensure that the impact of the Force Majeure Event shall not be relatively greater for Vericel than it is for MediWound with respect to MediWound's products (including EscharEx). 26 9012190/26 ARTICLE 11 MISCELLANEOUS 11.1 Assignment. Neither this Agreement nor any interest hereunder shall be assignable by a Party without the prior written consent of the other Party, except as follows: (a) such Party may assign its rights and obligations under this Agreement to any of its Affiliates, provided that the assignee shall expressly agree to be bound by such Party's obligations under this
