If installation is assumed by us and contractually agreed, the following provisions apply:
Until all debts, including open accounts, are met to which we have a claim or shall have a future claim against our customer based on all types of legal bases, the following securities are guaranteed to us, released on our request and at our choosing, insofar as their value consistently exceeds the debts by more than 20%.
If our customer fails to meet the contract or if the customer withdraws from a concluded contract for an unjustified reason, we shall be able to demand 35% of the agreed contractual price, notwithstanding possible higher actual damage, for processing the contract and profit lost. If the delivery object has been delivered, this amount shall increase to cover shipping costs and costs of possible reconditioning. The customer has the right to provide evidence of smaller damage.
