The supplier undertakes, at the supplier's cost and ex - pense, to take back transport packaging at the respective place of delivery. In the event that the supplier fails to fulfil this obligation, we are entitled to have the packaging re - moved and, if necessary, disposed of at the supplier's cost and expense.
The supplier shall be obligated to treat strictly confidentially any and all data as well as the conclusion and the contents of the contracts and any and all received illustrations, drawings, calculations and other documents and information. They may be disclosed to third parties only with our express consent. The duty of confidentiality shall survive the expiration or termination of the contract. It will cease to apply only if and to the extent that the know-how contained in the illustrations, drawings, calculations and other documents made available has become generally known.
