(1) Items of income beneficially owned by a resident of a Contracting State, wherever arising, not dealt with in the foregoing Articles of this Agreement shall be taxable only in that Contracting State.
(2) The provisions of paragraph 1 shall not apply to income, other than income from immovable property as defined in paragraph 2 of Article 6, if the beneficial owner of such income, being a resident of a Contracting State, carries on business in the other Contracting State through a permanent establishment situated therein and the right or property in respect of which the income is paid is effectively connected with such permanent establishment. In such case the provisions of Article 7 shall apply.
(3) Where, by reason of a special relationship between the resident referred to in paragraph 1 and the payer or between both of them and some other person, the amount of the income referred to in paragraph 1 exceeds the amount which would have been agreed upon between them in the absence of such relationship, 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 according to the laws of each Contracting State, due regard being had to the other provisions of this Agreement.
