Article 2
The undertakings named in Article 1 shall forthwith bring the said infringement to an end (if they have not already done so) and shall henceforth refrain in relation to their polypropylene operations from any agreement or concerted practice which may have the same or similar object or effect, including any exchange of information of the kind normally covered by business secrecy by which the participants are directly or indirectly informed of the output, deliveries, stock levels, selling prices, costs or investment plans of other individual producers, or by which they might be able to monitor adherence to any express or tacit agreement or to any concerted practice covering prices or market sharing inside the EEC. Any scheme for the exchange of general information to which the producers subscribe (such as Fides) shall be so conducted as to exclude any information from which the behaviour of individual producers can be identified and in particular the undertakings shall refrain from exchanging between themselves any additional information of competitive significance not covered by such a system.
