3. Denunciation shall take effect one year after the day on which the Director General has received the notification.

4. The right of denunciation provided for by this Article shall not be exercised by any country before the expiration of five years from the date upon which it becomes a member of the Special Union.

5. International marks registered up to the date on which denunciation becomes effective, and not refused within the period of one year provided for in Article 5, shall continue, throughout the period of international protection, to enjoy the same protection as if they had been filed direct in the denouncing country.
