Artikel 10

1. If a State engages in a commercial transaction with a foreign natural or juridical person and, by virtue of the applicable rules of private international law, differences relating to the commercial transaction fall within the jurisdiction of a court of another State, the State cannot invoke immunity from that jurisdiction in a proceeding arising out of that commercial transaction.
2. Paragraph 1 does not apply:
a) in the case of a commercial transaction between States; or
b) if the parties to the commercial transaction have expressly agreed otherwise.
3. Where a State enterprise or other entity established by a State which has an independent legal personality and is capable of:
a) suing or being sued; and
b) acquiring, owning or possessing and disposing of property, including property which that State has authorized it to operate or manage, is involved in a proceeding which relates to a commercial transaction in which that entity is engaged, the immunity from jurisdiction enjoyed by that State shall not be affected.
