Point (g) of the first subparagraph shall not affect terms by which the party that unilaterally imposed the term reserves the right to unilaterally change the terms of a contract of an indeterminate duration, provided that the contract specified a valid reason for such unilateral changes, that the party that unilaterally imposed the term is required to provide the other contracting party with reasonable notice of any such intended change, and that the other contracting party is free to terminate the contract at no cost in the case of a change. ### Article 13(6) **6.** A contractual term shall be considered to be unilaterally imposed within the meaning of this Article if it has been supplied by one contracting party and the other contracting party has not been able to influence its content despite an attempt to negotiate it. The contracting party that supplied the contractual term bears the burden of proving that that term has not been unilaterally imposed. The contracting party that supplied the contested contractual term may not argue that the term is an unfair contractual term. ### Article 13(7) **7.** Where the unfair contractual term is severable from the remaining terms of the contract, those remaining terms shall be binding. ### Article 13(8) **8.** This Article does not apply to contractual terms defining the main subject matter of the contract or to the adequacy of the price, as against the data supplied in exchange. ### Article 13(9) **9.** The parties to a contract covered by paragraph 1 shall not exclude the application of this Article, derogate from it, or vary its effects. ## Source Source: Regulation (EU) 2023/2854, OJ L, 2023/2854, 22.12.2023, as corrected.
