Section 9.10 Dispute Resolution.

(a) The Parties shall attempt to resolve any dispute or difference that may arise between them in relation to or in connection with this Agreement or the breach, termination or validity thereof (“Dispute”) by meeting to discuss and identify a resolution of the Dispute. The above meeting shall be held in a timely manner after one party has given written notice to the other Party that a Dispute has arisen (“Notice”). If the Dispute has not been resolved for any reason within forty (40) days of the receipt by a Party of Notice, either Party may initiate binding arbitration as provided in this Section 9.10.

(b) The arbitration shall be conducted under the then current Commercial Arbitration Rules (the “Rules”) of the American Arbitration Association (“AAA”). The arbitration shall be conducted before a panel of three arbitrators in Boston, Massachusetts. In deciding the Dispute, the arbitrators shall follow the substantive law of the State of Delaware. Each party shall appoint one arbitrator within twenty (20) days of receipt by respondent of a copy of the demand for arbitration; and the two party-appointed arbitrators together shall select the third arbitrator who shall be the panel chairperson within twenty (20) days of the appointment of the second arbitrator. Any arbitrator not timely appointed shall be appointed by the AAA in accordance with the Rules. Discovery in the arbitration shall be limited to documents directly relevant to the issues in dispute, and the arbitrators shall establish a schedule providing for a hearing on the merits to be held within one-hundred and twenty (120) days of the appointment of the third arbitrator or as soon thereafter as practicable. The determination and award of the arbitrators shall be in writing and shall state reasons for the arbitrators’ decision. All arbitration fees and costs shall be shared equally by the parties. The award of the arbitrators shall be final and binding on the parties and judgment upon the award rendered by the arbitrators may be entered and enforced in any court having jurisdiction over either party or any of its assets.

(c) Notwithstanding anything in this Agreement, prior to the appointment of the arbitral tribunal, no party shall be precluded from seeking provisional remedies in the courts including, but not limited to actions to compel arbitration or seeking, temporary restraining orders or preliminary injunctions, to protect its rights and interests, but such proceedings shall not be used as a means of delaying or avoiding the dispute resolution process set out in this Agreement. Each party unconditionally and irrevocably agrees to submit to the non-exclusive jurisdiction of the state and federal courts located in Boston, Massachusetts (the “Boston Courts”) for the purpose of any proceedings in aid of arbitration and for pre-arbitral attachment or a pre-arbitral injunction to maintain the status quo or prevent irreparable harm prior to the appointment of the arbitral panel, and for the enforcement of any award or decision of the arbitrators duly appointed under this Agreement. Each party unconditionally and irrevocably waives any objections which they may have now or in the future to the jurisdiction of the Boston Courts for such purpose, including without limitation objections by reason of lack of personal jurisdiction, improper venue, or inconvenient forum. Without prejudice to such provisional remedies as may be available under the jurisdiction of a court, the arbitral panel shall have full authority to grant provisional remedies to order a party to request that a court modify or vacate any provisional relief issued by such court and to award damages for the failure of any party to respect the arbitral panel’s orders to that effect.

Section 9.11 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. This Agreement may be executed by facsimile or .PDF signature.

Section 9.12 WAIVER OF JURY TRIAL. TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH PARTY HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR THE ACTIONS OF EITHER PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT.
