Article 22

This Convention shall remain in effect for a period of ten years as from the date of its coming into force. Any Contracting Party may, by giving twelve months' notice to the Secretary-General of the Organisation, terminate the application of this Convention to itself at the end of the period of ten years.

This Convention shall, after the period of ten years, remain in force for a period of five years for such Contracting Parties as have not terminated its application in accordance with paragraph (a) of this Article, and thereafter for successive periods of five years for such Contracting Parties as have not terminated its application at the end of one of such periods of five years by giving twelve months' notice to that effect to the Secretary-General of the Organisation.

The Contracting Parties shall consult each other at the expiry of each five year period following the date upon which this Convention comes into force, upon all problems of common interest raised by the application of this Convention, and in particular, to consider whether increases in the liability and financial security amounts under this Convention are desirable.

A conference shall be convened by the Secretary-General of the Organisation in order to consider revisions to this Convention after a period of five years as from the date of its coming into force or, at any other time, at the request of a Contracting Party, within six months from the date of such request.
