In the event that Customer is unable to comply with this obligation due to technical reasons, Customer will inform IBM thereof in writing. In this case, IBM shall be entitled to delete all data stored in/on the waste machines, as instructed and requested by Customer and according to the “IBM Supplementary Terms and Conditions for Processing of Customer Data by Order according to § 11 BDSG”;
