Specific contractual terms should be addressed in this Regulation, in particular in situations of imbalances in bargaining power, in order to ensure that contractual relations are conducted in good faith and on the basis of fair dealing. Predictability and transparency require that business users are given a real opportunity to become acquainted with changes to terms and conditions, which should therefore not be imposed with retroactive effect unless they are based on a legal or regulatory obligation or are beneficial to those business users. Business users should in addition be offered clarity as to the conditions under which their contractual relationship with providers of online intermediation services can be terminated. Providers of online intermediation services should ensure that the conditions for termination are always proportionate and can be exercised without undue difficulty. Finally, business users should be fully informed of any access that providers of online intermediation services maintain, after the expiry of the contract, to the information that business users provide or generate in the context of their use of online intermediation services.
