References and Links

In the case of direct or indirect references to external Internet pages (so-called “links”) which lie outside the area of responsibility of the Klumpen GmbH, no liability obligation exists except in the case in which it has knowledge of the contents and it would be technically possible and reasonable for it to prevent use in the case of illegal contents. Klumpen therefore expressly declares that at the time the links were created, the linked pages were free of illegal content. The Klumpen GmbH has no influence whatsoever on the current and future design and content of the linked pages. Therefore, it hereby expressly distances itself from all contents of all linked pages that were changed after the link was set. This statement applies to all links and references set within the company’s own website as well as to entries made by third parties in guest books, discussion forums or mailing lists set up by Klumpen. For illegal, incorrect or incomplete contents and in particular for damages arising from the use or non-use of such information, the provider of the page to which reference is made is solely liable, not the party who merely refers to the respective publication via links.
