Where an agency contract is concluded for an indefinite period either party may terminate it by notice.

The period of notice shall be one month for the first year of the contract, two months for the second year commenced, and three months for the third year commenced and subsequent years. The parties may not agree on shorter periods of notice.

Member States may fix the period of notice at four months for the fourth year of the contract, five months for the fifth year and six months for the sixth and subsequent years. They may decide that the parties may not agree to shorter periods.

If the parties agree on longer periods than those laid down in paragraphs 2 and 3, the period of notice to be observed by the principal must not be shorter than that to be observed by the commercial agent.

Unless otherwise agreed by the parties, the end of the period of notice must coincide with the end of a calendar month.

The provisions of this Article shall apply to an agency contract for a fixed period where it is converted under Article 14 into an agency contract for an indefinite period, subject to the proviso that the earlier fixed period must be taken into account in the calculation of the period of notice.
