meeting within five days of that notice, any Party may initiate arbitration of the controversy or claim as provided hereinafter. If a negotiator intends to be accompanied at a meeting by an attorney, the other negotiators shall be given at least three Business Days’ notice of that intention and may also be accompanied by an attorney. All negotiations pursuant to this clause 12.7. (a) shall be treated as compromise and settlement negotiations for the purposes of applicable rules of evidence and procedure.

(b)           Arbitration. Any Dispute that has not been resolved by non-binding procedures as provided in clause 12.7. within 60 days of delivery of the Notice of Dispute, shall be finally resolved by arbitration conducted expeditiously in accordance with the American Arbitration Association (“AAA”) International Arbitration Rules for commercial disputes, as in effect on the date hereof (the “Rules”); provided, that if one Party has requested the other to participate in a non-binding procedure and the other has failed to participate, the requesting Party may initiate arbitration before the expiration of the period. With respect to an arbitral proceeding, the Parties hereby agree as follows:

Any Dispute shall be referred to and determined by binding arbitration, as the sole and exclusive remedy of the Parties as to the Dispute, conducted in accordance with the Rules, which are hereby incorporated by reference, except that in the event of any conflict between those rules and the arbitration provisions set forth below, the provisions set forth below shall govern and control. The arbitral tribunal (the “Tribunal”) shall use the substantive laws of Texas (USA), excluding conflicts of laws and choice of law principles, in construing and interpreting the terms of this Agreement. The Tribunal shall be composed of three arbitrators, with GGS appointing one arbitrator and Sercel appointing one arbitrator, and the two arbitrators so appointed appointing the third arbitrator who shall act as the presiding arbitrator of the Tribunal (the “Chairman”). All of the arbitrators shall be neutral arbitrators. Further, should the two arbitrators fail to choose a Chairman for any reason, the AAA shall select such Chairman on the basis used to select arbitrators for Tribunals employed by the AAA. The language of the arbitration, the submission of all writings, the decision of the Tribunal, and the reasons supporting such decision shall be in English. The arbitration shall be held in Houston, Texas, and the proceedings shall be conducted and concluded as soon as reasonably practicable, based upon the schedule established by the Tribunal, but in any event the award of the Tribunal shall be rendered within 180 days following the selection of the Chairman of the Tribunal. No award shall be made for punitive, special, exemplary, or consequential damages, including loss of profits or loss of business opportunity. Any monetary award shall be made in U.S. Dollars, free of any tax or other deduction, and shall include interest from the date of any breach or other violation of the Agreement to the date paid in full at a per annum rate of 10%. The award of the Tribunal pursuant hereto shall be final and binding upon the Parties, and judgment upon the award rendered by the Tribunal pursuant hereto may be entered in, and enforced by, any court of competent jurisdiction.   Each Party shall bear the expense of the arbitrator specified to be selected by it, and the fees of the Chairman of the Tribunal and other expenses incurred by the Tribunal shall be borne as determined by the arbitrators. Each Party shall bear its own expenses, including expenses of its counsel. Any attorney-client privilege and other protection against disclosure of privileged or confidential information, including without limitation, any protection afforded the work-product of any attorney, that could otherwise be claimed by any Party shall be available to, and may be claimed by, any such Party in any arbitration proceeding. No Party waives any attorney-client privilege or any other protection against disclosure of privileged or confidential information by reason of anything contained in, or done pursuant to, the arbitration provisions hereof. It is the desire of the Parties that any Dispute be resolved quickly and at the lowest possible cost, and the Tribunal shall act in a manner consistent with these intentions, including limiting discovery to only that necessary to enable the Tribunal to render a fair decision that reflects the Parties’ intent set forth in this Agreement.
