If such dispute is not resolved within ninety (90) days of the first written request for mediation, either Party may seek arbitration of the matter as set forth herein. Notwithstanding anything in this Agreement to the contrary, any Party shall be entitled to seek equitable relief any time if the same shall be necessary to prevent irreparable harm to any Party.

(b) Except with respect to equitable relief and disputes relating to the Intellectual Property Rights of any Party, which may be obtained in a court of competent jurisdiction, if the Parties are unable to resolve any dispute through the mediation provisions set forth above, such dispute shall be finally resolved by arbitration. The arbitration shall be in accordance with the Commercial Arbitration Rules (“Rules”) of the AAA which shall administer the arbitration and act as appointing authority; provided that the arbitrator(s) appointed with regard to the arbitration proceeding shall not be the same persons who served as mediated in any mediation between the Parties. In addition to such discovery as may be provided for in the Rules, the Parties agree to permit (i) up to three depositions per Party and (ii) up to 15 interrogatories per Party, provided that the arbitrator(s) agree that such depositions and interrogatories are appropriate after hearing the Parties on the subject thereof. In the, event of any conflict between the Rules and the provisions of this Section 15.2, the provisions of this Section 15.2 shall govern. If the amount in controversy exceeds $50,000, then the arbitration shall be heard and determined by a panel of three arbitrators selected in accordance with the procedures of the AAA. The arbitration, including the rendering of the award, shall take place at such location as the Parties may agree and, if no location can be agreed, at such location as the AAA directs. Judgment upon the award of the arbitrators may be entered in any court having jurisdiction thereof. In the event of any arbitration or other legal proceeding brought by any Party against another Party with regard to any matter arising out of or related to this Agreement, each Party hereby expressly agrees that the final award may also provide for an allocation and division between or among the Parties to the arbitration, on a basis which is just and equitable under the circumstances, of all costs of arbitration, including court costs and arbitrators’ fees but not attorneys’ fees; provided, however, that attorneys’ fees may be awarded against a Party if the arbitrators specifically find willful misconduct by that Party.
