1.The provisions of this Article shall apply notwithstanding any other provisions of this Convention where the Governments of the two Contracting States have entered into an Agreement relating to the joint exploitation of a field which extends across the dividing line and that Agreement expressly provides for the application of these provisions.
2.Irrespective of where the production installations for a field are located, a Contracting State may, subject to paragraph 3, tax, in accordance with the laws of that State, profits from the exploitation of the field which arise to a licensee of that State and shall not tax any such profits which arise to a licensee of the other Contracting State.
3.For the purposes of the application of the laws of a Contracting State relating to the taxation of profits arising from the exploitation of the field, a licensee shall be treated as having lifted over the production life of the field so much of the total production of that field as is attributed to that licensee under the final apportionment of the field made in accordance with an Agreement as mentioned in paragraph 1. However, in any accounting period or chargeable period a licensee may be charged to tax only on the profits from the oil (including gas and other hydrocarbons) lifted in that or earlier periods by the licensee and on any compensation receivable by the licensee for underliftings in that or earlier periods.
4.A Contracting State may tax gains realised on the disposal of installations and equipment used for the joint exploitation of the field which are owned, wholly or partly, by a licensee of that State, regardless of the side of the dividing line between the two States on which the installations and equipment are situated. Where such assets are owned partly by a licensee of that State and partly by a licensee of the other Contracting State each State may tax its own licensees in respect of such part only of the gains as is proportionate to the interest of its licensees in those assets. However, a Contracting State shall not tax gains realised on the disposal of such assets as are wholly owned by a licensee of the other Contracting State.
5.Any profits or gains derived by a person in his capacity as the Unit Operator for the field shall be taxable only in the Contracting State of which that Unit Operator is a licensee.
