The award rendered therein shall be final and binding upon the parties to such arbitration proceedings. However, submission to arbitration shall not preclude the ability of either party in the first instance to seek injunctive relief pending the outcome of subsequent arbitration. The courts of Amsterdam, the Netherlands, shall have exclusive competence for a procedure of injunctive relief.
