1.2 Arbitration of Dispute Resolution

a. Any dispute, claim or controversy arising from or related in any way to this Agreement or the interpretation, application, breach, termination or validity thereof, including any claim of inducement of this Agreement by fraud or otherwise, will be submitted for resolution to arbitration pursuant to the rules then pertaining of the [***], except where those rules conflict with these provisions, in which case these provisions control. The arbitration will be held in [***].

b. The panel shall consist of three arbitrators chosen from the [***] (or, by agreement, from another provider of arbitrators) each of whom is a lawyer with at least 15 years experience with a law firm or corporate law department of over 25 lawyers or who was a judge of a court of general jurisdiction. In the event the aggregate damages sought by the claimant are stated to be less than [***], and the aggregate damages sought by the counterclaimant are stated to be less than [***], and neither side seeks equitable relief; then a single arbitrator shall be chosen, having the same qualifications and experience specified above. Each arbitrator shall be neutral, independent, disinterested, impartial and shall abide by [***]

c. The parties agree to cooperate (1) to attempt to select the arbitrator(s) by agreement within [***] calendar days of initiation of the arbitration, including jointly interviewing the final candidates, (2) to meet with the arbitrator(s) within [***] calendar days of selection and (3) to agree at that meeting or before upon procedures for discovery and as to the conduct of the hearing which will result in the hearing being concluded within no more than [***] months after selection of the arbitrator(s) and in the award being rendered within [***] calendar days of the conclusion of the hearings, or of any post-hearing briefing, which briefing will be completed by both sides within [***] calendar days after the conclusion of the hearings.

d. In the event the parties cannot agree upon selection of the arbitrator(s), the [***] will select arbitrator(s) as follows: [***] shall provide the parties with a list of no less than [***] proposed arbitrators ([***] if a single arbitrator is to be selected) having the credentials referenced above. Within [***] calendar days of receiving such list, the parties shall rank at least [***] of the proposed arbitrators on the initial [***] list, after exercising cause challenges. The parties may then interview the [***] candidates ([***] if a single arbitrator is to be selected) with the highest combined rankings for no more than [***] each and,

following the interviews, may exercise one peremptory challenge each. The panel will consist of the remaining three candidates (or one, if one arbitrator is to be selected) with the highest combined rankings. In the event these procedures fail to result in selection of the required number of arbitrators, [***] shall select the appropriate number of arbitrators from among the members of the various [***] peremptory challenges each.

e. In the event the parties cannot agree upon procedures for discovery and conduct of the hearing meeting the schedule set forth in paragraph c above, then the arbitrator(s) shall set dates for the hearing, any post-hearing briefing, and the issuance of the award in accord with the paragraph c schedule. The arbitrator(s) shall provide for discovery according to those time limits, giving recognition to the understanding of the parties that they contemplate reasonable discovery, including document demands and depositions, but that such discovery be limited so that the paragraph c schedule may be met without difficulty. In no event will the arbitrator(s), absent agreement of the parties, allow more than a total of ten calendar days for the hearing or permit either side to obtain more than a total of [***] hours of deposition testimony from all witnesses, including both fact and expert witnesses, or serve more than [***] individual requests for documents, including subparts, or [***] individual requests for admission or interrogatories, including subparts. Multiple hearing calendar days will be scheduled consecutively to the greatest extent possible.

f. The arbitrator(s) must render their award by application of the substantive law of New Jersey and are not free to apply “amiable compositeur” or “natural justice and equity.” The arbitrator(s) shall render a written opinion setting forth findings of fact and conclusions of law with the reasons therefor stated. A transcript of the evidence adduced at the hearing shall be made and shall, upon request, be made available to either party. The arbitrator(s) shall have power to exclude evidence on grounds of hearsay, prejudice beyond its probative value, redundancy, or irrelevance and no award shall be overturned by reason of such ruling on evidence. To the extent possible, the arbitration hearings and award will be maintained in confidence.

g. In the event the panel’s award exceeds [***] by agreement or, failing agreement within seven working days, pursuant to the selection procedures specified in paragraph d above. If [***] cannot provide such services, the parties will together select another provider of arbitration services that can. No Appeal Arbitrator shall be selected unless he or she can commit to rendering a decision within [***] calendar days following oral argument as provided in paragraph h. Any such review must be initiated within [***] calendar days following the rendering of the award referenced in f above.

h. The Appeal Arbitrator will make the same review of the arbitration panel’s ruling and its bases that the U.S. Court of Appeals of the Circuit where the arbitration hearings are held would make of findings of fact and conclusions of law rendered by a district court after a bench trial and then modify, vacate or affirm the arbitration panel’s award or decision accordingly, or remand to the panel for further proceedings. The Appeal Arbitrator will consider only the arbitration panel’s findings of fact and conclusions of law, pertinent portions of the hearing transcript and evidentiary record as submitted by the parties, opening and reply briefs of the party pursuing the review, and the answering brief of the opposing party, plus a total of no more than [***] hours of oral argument evenly divided between the parties. The party seeking review must submit its opening brief and any reply brief within [***] and [***] calendar days, respectively, following the date of the award under review, whereas the opposing party must submit its responsive brief within [***] calendar days of that date. Oral argument shall take place within [***] months after the date of the award under review, and the Appeal Arbitrator shall render a decision within [***] calendar days following oral argument. That decision will be final and not subject to further review, except pursuant to the Federal Arbitration Act.

i. The parties consent to the jurisdiction of the Federal District Court for the district in which the arbitration is held for the enforcement of these provisions and the entry of judgment on any award rendered hereunder (including after review by the Appeal Arbitrator where such an appeal is pursued). Should such court for any reason lack jurisdiction, any court with jurisdiction shall act in the same fashion.

j. Each party has the right before or, if the arbitrator(s) cannot hear the matter within an acceptable period, during the arbitration to seek and obtain from the appropriate court provisional remedies such as attachment, preliminary injunction, replevin, etc. to avoid irreparable harm, maintain the status quo, or preserve the subject matter of the arbitration.

l. EACH PARTY HERETO WAIVES ANY CLAIM TO PUNITIVE, EXEMPLARY OR MULTIPLIED DAMAGES FROM THE OTHER.

m. EACH PARTY HERETO WAIVES ANY CLAIM OF CONSEQUENTIAL DAMAGES FROM THE OTHER.
