1. Staging points shall be used exclusively to receive, feed, water, rest, accommodate, care for and dispatch animals passing through. 2. However, by way of derogation from paragraph 1 of this Article, Member States may also approve as staging points assembly centres as defined in Article 2 (o) of Directive 64/432/EEC provided that they comply with the following when used as staging points: (a) they satisfy the relevant requirements of Article 11 of Directive 64/432/EEC and the requirements of this Regulation; (b) the use of such facilities is exclusively reserved for this purpose during the period concerned; (c) they are not used for the purchase or sale of animals covered by this Regulation. 3. Only animals of the same certified health status belonging to the species concerned and for which the staging points are approved may be present at the same time at stating points in order not to jeopardize the animals' health status.
