As a result of the foregoing termination, effective on the Termination Date and thereafter during any period which Sanofi is required to perform any wind-down activities pursuant to the terms of the Sanofi License Agreement, the rights granted to Sanofi under the Sanofi License Agreement to develop and commercialize AFREZZA will become non-exclusive and the Company will have the right to engage one or more other distributors and/or licensees of AFREZZA. Sanofi will continue to distribute AFREZZA during the wind-down period as required by the agreement until such time that the Company or its designee takes over responsibility for distribution.
