Reservations referred to in paragraph 2 shall be valid for five years from the first day of application of this Convention by the Member State concerned. However, such reservations may be renewed for successive periods of the same duration.

12 months before the date of expiry of the reservation, the depositary shall give notice of that expiry to the Member State concerned.

No later than three months before the expiry of each five-year period, the Member State shall notify the depositary either that it is upholding its reservation, that it is amending it to ease the conditions for extradition or that it is withdrawing it.

In the absence of the notification referred to in the preceding subparagraph, the depositary shall inform the Member State concerned that its reservation is considered to have been extended automatically for a period of six months, before the expiry of which the Member State must give notification. On expiry of that period, failure to notify shall cause the reservation to lapse.
