(1) The parties shall be liable without limitation in cases of intent, gross negligence, and for culpable injury to life, body, or health.
(2) Without prejudice to the cases of unlimited liability under paragraph 1, the parties shall be liable to each other for damages arising from negligent breaches of duty only where such breaches concern essential contractual obligations i.e., obligations whose fulfillment is a prerequisite for the proper performance of the agreement, whose breach endangers the achievement of the contractual purpose, and on whose compliance the other party regularly relies. In such cases, liability shall be limited to the foreseeable, typical damage at the time of conclusion of the agreement.
(3) The above limitations of liability shall not apply to liability under the Product Liability Act, nor to liability arising from written guarantees expressly assumed by a party.
