English and Portuguese.  The parties agree that the arbitration shall be kept confidential and that the existence of the proceeding and any element of it (including but not limited to any pleadings, briefs or other documents submitted or exchanged, any testimony or other oral submissions, and any awards) shall not be disclosed beyond the tribunal, the ICC, the parties, their counsel and any person necessary to the conduct of the proceeding, except as may be lawfully required in judicial proceedings relating to the arbitration or otherwise, or as required by applicable Law.  The decision of the tribunal shall be final, binding and enforceable upon the parties and judgment upon any award rendered by the tribunal may be entered in any court having jurisdiction thereof.  In the event that the failure of a party to this Agreement to comply with the decision of the tribunal requires the other party to apply to any court for enforcement of such award, the non-complying party shall be liable to the other for all costs of such litigation including attorneys’ fees.  The parties may apply to any court of competent jurisdiction in accordance with this Section 24.1 for temporary or permanent injunctive or preliminary relief, without breach of this Section 24. or abridgement of the powers of the tribunal.  For the purposes of obtaining temporary or permanent injunctive or preliminary relief and without abridgement of the powers of the tribunal, the parties elect the courts of the City of Sao Paulo, State of Sao Paulo, with the express waiver of any other courts, no matter how privileged they may be.  Except for applications regarding preliminary or injunctive relief, neither party shall be entitled to commence or maintain any action in any court of law upon any matter in dispute until such matter shall have been submitted to, and finally determined under, the dispute resolution and arbitration procedures in this Section 24.  Process may be served on either party in the manner set forth in this Agreement or by such other method authorized by applicable Law or court rule.
