1. The contract enters into force and becomes binding on the parties from the time of its conclusion. 2. The parties shall have the right to establish that the conditions of the contract concluded by them apply to their relations that arose before the conclusion of the contract. 3. A law or contract may provide that the termination of the term of the contract entails the termination of the obligations of the parties under the contract.
