Article 7 — Suspension of concentrations

1. A concentration with a Community dimension as defined in Article 1, or which is to be examined by the Commission pursuant to Article 4(5), shall not be implemented either before its notification or until it has been declared compatible with the common market pursuant to a decision under Articles 6(1)(b), 8(1) or 8(2), or on the basis of a presumption according to Article 10(6).
2. Paragraph 1 shall not prevent the implementation of a public bid or of a series of transactions in securities including those convertible into other securities admitted to trading on a market such as a stock exchange, by which control within the meaning of Article 3 is acquired from various sellers, provided that:
   1. the concentration is notified to the Commission pursuant to Article 4 without delay; and
   2. the acquirer does not exercise the voting rights attached to the securities in question or does so only to maintain the full value of its investments based on a derogation granted by the Commission under paragraph 3.
3. The Commission may, on request, grant a derogation from the obligations imposed in paragraphs 1 or 2. The request to grant a derogation must be reasoned. In deciding on the request, the Commission shall take into account inter alia the effects of the suspension on one or more undertakings concerned by the concentration or on a third party and the threat to competition posed by the concentration. Such a derogation may be made subject to conditions and obligations in order to ensure conditions of effective competition. A derogation may be applied for and granted at any time, be it before notification or after the transaction.
4. The validity of any transaction carried out in contravention of paragraph 1 shall be dependent on a decision pursuant to Article 6(1)(b) or Article 8(1), (2) or (3) or on a presumption pursuant to Article 10(6).

   This Article shall, however, have no effect on the validity of transactions in securities including those convertible into other securities admitted to trading on a market such as a stock exchange, unless the buyer and seller knew or ought to have known that the transaction was carried out in contravention of paragraph 1.
