The application for admission to official listing must cover all the shares of the same class already issued.

Member States may provide that this condition shall not apply to applications for admission not covering all the shares of the same class already issued where the shares of that class for which admission is not sought belong to blocks serving to maintain control of the company or are not negotiable for a certain time under agreements, provided that the public is informed of such situations and that there is no danger of such situations prejudicing the interests of the holders of the shares for which admission to official listing is sought.
