(b) Any Dispute shall be finally settled by arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association ("AAA") effective as of the commencement of the arbitration (the "Rules"), except as such Rules may be modified as provided herein. The arbitration shall be held in New York, New York, unless the parties mutually agree to have the arbitration held elsewhere, and judgment upon the award made therein may be entered by any court having jurisdiction thereof provided, however, that nothing contained in this Section 9.1 shall be construed to preclude a party from bringing any action in any court of competent jurisdiction for injunctive or other provisional relief to compel another party to comply with its obligations under this Agreement during the pendency of the arbitration proceedings. The arbitral tribunal shall be composed of three arbitrators, whose names shall be set forth on a list of arbitrators approved by the AAA and who shall be experienced litigators admitted to practice law in the State of New York.

The arbitrators shall have no power to waive, alter, amend, revoke or suspend any of the provisions of this Agreement; provided, however, that the arbitrators shall have the power to decide all questions with respect to the interpretation and validity of this Section 9.1. The arbitration shall be conducted, and the award shall be rendered, in the English language. An arbitrator may not act as an advocate for the party nominating him, and all three arbitrators shall be impartial and unbiased. A majority vote by the three arbitrators shall be required on any decision made by them; provided, however, that lacking such a majority in the case of questions of amounts of dollar or other quantities the vote for the greatest amount or quantity shall be deemed to be a vote for the amount or quantity next in magnitude in order to form a majority for such vote. The arbitrators shall permit such discovery as they shall determine is appropriate in the circumstances taking into account the needs of the parties and the desirability of making discovery expeditious and cost effective. Any such discovery shall be limited to information directly relevant to the controversy or claim in arbitration and shall be concluded within thirty days after the appointment of the arbitration panel. This agreement to arbitrate shall be binding upon the successors and assigns of any party hereto. Except to the extent required by law or court or administrative order, no party, arbitrator, representative, counsel or witness shall disclose or confirm to any person not present at the arbitration hearings any information about the arbitration proceeding or hearings, including the names of the parties and arbitrators, the nature and amount of the claims, the financial condition of any party the expected date of hearing or the award made.
