The provisions of the legislation of any Member State which make admission to voluntary or optional continued insurance conditional upon residence in the territory of that State shall not apply to persons resident in the territory of another Member State, provided that at some time in their past working life they were subject to the legislation of the first State as employed or as self-employed persons.

Where under the legislation of a Member State, admission to voluntary or optional continued insurance is conditional upon completion of periods of insurance, the periods of insurance or residence completed under the legislation of another Member State shall be taken into account, to the extent required, as if they were completed under the legislation of the first State.
