(1) Royalties arising in a Contracting State and whose beneficial owner is a resident of the other Contracting State shall be taxable only in that other State.
(2) The term "royalties" as used in this Article means payments of any kind received as a consideration for the use of, or the right to use, any copyright of literary, artistic or scientific work, including cinematograph films, any patent, trademark, design or model, plan, secret formula or process and for any information related with experience acquired in the field of industry, commerce, or science (know-how).
(3) The provisions of paragraph (1) of this Article shall not apply if the beneficial owner of the royalties, being a resident of a Contracting State, carries on an industrial or commercial activity in the other Contracting State in which the royalties arise, through a permanent establishment situated therein, or performs in that other State independent personal services from a fixed base situated therein, and the right or property in respect of which the royalties are paid is effectively connected therewith. In such case the provisions of Article 7 or Article 14 of this Convention, as the case may be, shall apply.
(4) Where, by reason of a special relationship between the payer and the beneficial owner or between both of them and some third parties, the amount of the royalties, having regard to the service for which they are paid, exceeds the amount which would have been agreed upon by the payer and the beneficial owner in the absence of similar relationships, the provisions of this Article shall apply only to the last-mentioned amount. In such case, the excess part of the payments shall remain taxable in accordance with the laws of each Contracting State, due regard being had to the other provisions of this Convention.
