This does not apply if we are liable under law, e.g. under the Product Liability Law, in cases of intent, gross negligence, due to injury to life, limb or health, and in the case of a breach of essential contractual obligations. Compensation claims for the breach of essential contractual obligations, however, are limited to foreseeable damage typical for the contract, unless we have acted with intent or gross negligence or are liable due to injury to life, limb or health. The preceding provisions do not bring about a change in the burden of proof to the disadvantage of the buyer.
