Article 64 2.

If the person concerned returns to the competent Member State on or before the expiry of the period during which he/she is entitled to benefits under paragraph 1(c), he/she shall continue to be entitled to benefits under the legislation of that Member State. He/she shall lose all entitlement to benefits under the legislation of the competent Member State if he/she does not return there on or before the expiry of the said period, unless the provisions of that legislation are more favourable. In exceptional cases the competent services or institutions may allow the person concerned to return at a later date without loss of his/her entitlement.
