Artikel 9

1. Each member may, by written communication to the Director General, propose amendments to this Agreement. The Director General shall communicate these proposals to all Organisation members. If, within six months from the date of the communication, one half plus one of the members reply favourably to the proposal, the Director General shall present it for adoption at the first General Assembly held after this period. Amendments shall be adopted by consensus of the members present or represented. Once adopted by the General Assembly, amendments shall be subject to internal procedures for acceptance, approval or ratification set out in the domestic legislation of members. Amendments shall enter into force thirty days after the deposit of the instrument of acceptance, approval, ratification or accession representing two thirds plus one of the members of the organisation.
2. This Agreement shall be reviewed if two thirds plus one of members approve a request to that effect. In such case, the Government of the French Republic shall convene a conference of members within six months. The programme as well as the revision proposed shall be provided to members at least two months before the conference meets. The conference shall decide its own rules of procedure. The Director General of the O.I.V shall act as Secretary General.
3. Before a revised agreement enters into force, the General Assembly of the Organisation shall define, under conditions determined by the present Agreement and by the Internal Rules in Article 10, to what extent the members party to the present Agreement, who have not deposited an instrument of acceptance, approval, ratification or accession may participate in the O.I.V's activities after it has entered into force.
