(1) Royalties arising in a Contracting State and paid to a resident of the other Contracting State may be taxed in that other State.
(2) However, such royalties may be taxed in the Contracting State in which they arise, and according to the law of that State, but the tax so charged shall not exceed 10 per cent of the gross amount of the royalties.
(3) 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 and television films, any patent, trade mark, design or model, plan, secret formula or process, or for the use of, or the right to use, agricultural, industrial, commercial or scientific equipment, not being immovable property within the meaning of Article 6, or for information concerning agricultural, industrial, commercial or scientific experience, and remuneration for economic or technical studies.
(4) The provisions of paragraphs (1) and (2) shall not apply if the recipient of the royalties, being a resident of a Contracting State, has in the other Contracting State in which the royalties arise a permanent establishment with which the right or property giving rise to the royalties is effectively connected. In such a case, the provisions of Article 7 shall apply.
(5) Royalties shall be deemed to arise in a Contracting State when the payer is that State itself, one of its Lander, political subdivisions or local authorities, or a resident of that State. Where, however, the person paying the royalties, whether he is a resident of a Contracting State or not, has in a Contracting State a permanent establishment in connection with which the contract giving rise to the royalties was concluded, and the royalties are borne as such by the permanent establishment, then such royalties shall be deemed to arise in the Contracting State in which the permanent establishment is situated.
(6) Where, owing to a special relationship between the payer and the recipient or between both of them and some other person, the amount of the royalties paid, having regard to the use, right or information for which they are paid, exceeds the amount which would have been agreed upon by the payer and the recipient in the absence of such relationship, the provisions of this Article shall apply only to the last-mentioned amount. In that case, the excess part of the payments shall remain taxable according to the law of each Contracting State, due regard being had to the other provisions of this Convention.
