Artikel 10

1. If one of the Contracting Parties considers it desirable to amend any provision of this Agreement, it may request consultation with the other Contracting Party.
Such consultation, which may be carried out either verbal or in writing, shall take place within a period of two months to be reckoned from the day when the request has been made. The amendments thus agreed upon, shall be effective on the first day of the second month following the date on which the Contracting Parties have informed each other in writing that the amendments have been approved in their respective countries in conformity with the constitutional requirements.
2. The competent authorities of the two Contracting Parties may each amend the Parts of Annexes I, II, III and IV which relate to their own country.
Such amendments shall be communicated to the competent authorities of the other Contracting Party through diplomatic channels. Each Contracting Party shall endeavour to notify the other Contracting Party of the amendments before these become effective.
