Dispute Resolution


The parties shall use their best efforts to settle any dispute, claim, question, or disagreement directly through good-faith negotiations, which shall be a precondition to either party initiating a lawsuit or arbitration. Except for disputes relating to the NK's intellectual property (such as trademarks, trade dress, domain names, trade secrets, copyrights, and patents), all claims arising out of or relating to this Agreement and your use of the Services shall be finally settled by binding arbitration administered by JAMS in accordance with its provisions and procedures for consumer-related disputes, excluding any rules or procedures governing or permitting class actions. The arbitration shall be in Philadelphia, Pennsylvania. The arbitrator, and not any court or agency, shall have exclusive authority to resolve all disputes arising out of or relating to this Agreement, including, but not limited to, any claim that all or any part of this Agreement is void or voidable. The arbitrator shall be empowered to grant whatever relief would be available in a court; provided, however, that the arbitrator will not have authority to award damages, remedies, or awards that conflict with this Agreement. The arbitrator's award shall be binding on the parties and may be entered as a judgment in any court of competent jurisdiction. You and NK hereby expressly waive trial by jury. You also agree not to participate in claims brought in a private attorney general or representative capacity, or consolidated claims involving another person's account if NK is a party to the proceeding. This dispute resolution provision will be governed by the Federal Arbitration Act. The parties understand that, absent this mandatory provision, they would have the right to sue in court and have a jury trial. They further understand that, in some instances, the costs of arbitration could exceed the costs of litigation and that the right to discovery may be more limited in arbitration than in court. You agree that any claim you may have arising out of or related to your relationship with NK and these Terms must be filed within one year after such claim arose; otherwise, your claim is permanently barred.

Class-Action Waiver

The parties further agree that any arbitration shall be conducted in their individual capacities only, and not as a class action or other representative action. If any court or arbitrator determines that the class-action waiver set forth in this section is void or unenforceable for any reason, or that an arbitration can proceed on a class basis, then the arbitration provision set forth above shall be deemed null and void in its entirety and the parties shall be deemed to have not agreed to arbitrate disputes.

Exception — Litigation of Small-Claims-Court Claims

Notwithstanding the parties' decision to resolve all disputes through arbitration, either party may also seek relief in a small claims court for disputes or claims within the scope of that court's jurisdiction.

Choice of Law and Forum

All matters relating to your access to or use of the Services, including all disputes, shall be governed by and construed in accordance with the laws of the Commonwealth of Pennsylvania, USA, without regard to its conflicts of law principles.

Subject to the Section entitled "Dispute Resolution", the exclusive jurisdiction and venue with respect to any action or suit arising out of or pertaining to the subject matter hereof shall be the courts of competent jurisdiction located in the Commonwealth of Pennsylvania, USA. Any claim arising out of or in connection with your use of or inability to use the Services or its Content, products or services must be brought within one (1) year after the event or such claim is barred.

If any provision of the Terms is found by a court of competent jurisdiction to be invalid, the parties nevertheless agree that the court should endeavor to give effect to the parties' intentions as reflected in the provision, and the other provisions of the Terms remain in full force and effect. NK's notice to you via email, notices, posts, or links on the Services shall constitute acceptable notice to you under the Terms. We are not responsible for your failure to receive notice if email is quarantined by your email security system (e.g., "junk" or "spam" folder) or if you fail to update your email address. Notice will be considered received forty-eight hours after it is sent if transmitted via email or regular mail.
