translate English to German: No modification, waiver, or amendment hereof shall be binding unless stated in writing by both parties, and no waiver of a right in any instance shall constitute a waiver of the same or any other right in any other instance. If any provision of this agreement shall be held to be invalid, illegal, or unenforceable, such provisions shall be enforced to the maximum extent permitted by law and to the parties' fundamental intentions hereunder, and the remaining provisions shall not be affected.
Sollte eine Vertragsklausel ungÃ¼ltig sein, so ist sie durch eine gÃ¼ltige zu ersetzen, die dem Sinn der ersetzten Klausel am ehesten entspricht.
