Artikel III

1. States which are parties to the Agreement of the fifteenth of February, 1952, referred to in the Preamble hereto, or which have contributed in money or in kind to the Council thereby established and actually participated in its work, shall have the right to become members of the Organization by becoming parties to this Convention in accordance with the provisions of Articles XV, XVI and XVII.
2. a. Other States may be admitted to the Organization by the Council referred to in Article IV by a unanimous decision of all the Member-States.
b. If a State wishes to join the Organization in accordance with the provisions of the preceding sub-paragraph, it shall notify the President of the Council. The President shall inform all Member States of this request at least three months before it is discussed by the Council. States accepted by the Council may become members of the Organization by acceding to this Convention in accordance with the provisions of Article XVII.
3. Each Member State shall signify in writing to the President of the Council those programmes of activities in which it wishes to participate. No State shall be entitled to become or to remain a member of the Organization unless it participates in at least one of the programmes of activities forming part of the basic programme.
4. The Council may, by a two-thirds majority of all the Member States, determine a minimum initial period of participation in any programme of activities together with a limit on the expenditure that may be incurred for that programme during that period. Once this period of participation and limit of expenditure have been so determined, the Council may, by the same majority, change either provided that no Member State participating in the programme votes to the contrary. Subject to any such minimum period of participation, a Member State may at any time give notice in writing to the President of the Council of withdrawal from any programme, and such withdrawal shall take effect at the end of the financial year following that in which notice is given, or on such later date as the Member State proposes.
5. In the event that a programme of activities comes to an end, the Council shall be responsible for its liquidation, subject to any agreement which may be made at the time between the Member States participating in that programme, and subject also to the relevant terms of any agreement which exists between the Organization and the States on the territories of which the programme is being carried out. Any surplus shall be distributed among those Member States which are participating in the programme at the time of its termination, in proportion to the total contributions actually made by them in respect of that programme. In the event of a deficit, this shall be met by the same Member States in the same proportions as those in which their contributions in respect of the programme have been assessed for the financial year then current.
6. Member States shall facilitate, for the purposes of the activities of the Organization, the exchange of persons and of relevant scientific and technical information, provided that nothing in this paragraph shall
a. affect the application to any person of the laws and regulations of Member States relating to entry into, residence in, or departure from, their territories, or
b. require any Member State to communicate, or to permit the communication of any information in its possession insofar as it considers that such communication would be contrary to the interests of its security.
