Until the Client acquires the title to the Performance, it must not dispose of the Performance, or process the Performance in any manner without the previous written approval of KIN. If the Client disposes of the Performance, the Client must notify the person towards whom a disposal act is carried out of the reservation of the title by KIN.

The risk of damage to the Performance passes to the Client: (a) upon delivery of the Performance to the Client, or upon handover to the first carrier for the transportation of the Performance to the Client; (b) in the case of the Performance including the assembly or installation, upon proper completion of the assembly or installation, or upon completion of the pilot operation, if agreed. If the pilot operation is agreed, it must commence without delay after the installation or assembly is completed. Should the pilot operation not begin within 5 (five) days after the installation or assembly is completed, the risk of damage to the Performance passes to the Client upon expiry of this period, unless otherwise agreed.   6.3. Should the acceptance of the Performance be delayed due to reasons for which the Client is responsible, the risk of damage to the Performance passes to the Client on the first day of the delay.

Such materials may only be disclosed to a third party with previous written approval of KIN, and shall be returned to KIN upon its request without undue delay.
