Article 14
This Agreement shall be concluded for an initial period of three years from the date of its entry into force. Unless one of the Parties ends it by giving notice to that effect six months before the date of expiry of the three-year period, it shall remain in force for further periods of two years unless denounced by notice given at least three months before the date of expiry of each such two-year period.
At the end of the three-year period, and thereafter at the end of each two-year period, the Contracting Parties shall enter into negotiations to determine by common agreement what amendments or additions to the Annex or Protocol are required. The Contracting Parties shall also enter into negotiations when one of them gives notice denouncing the Agreement.
