DISPUTES
Informal Negotiation
To expedite resolution and control the cost of any dispute, controversy, or claim related to these Terms (each a "Dispute" and collectively, the “Disputes”) brought by either you or us (individually, a “Party” and collectively, the “Parties”), the Parties agree to first attempt to negotiate any Dispute (except those Disputes expressly provided below) informally for at least sixty (60) days before initiating arbitration. Such informal negotiations commence upon written notice from one Party to the other Party.
If the Parties are unable to resolve a Dispute through informal negotiations, the Dispute will be finally and exclusively resolved by binding arbitration. YOU UNDERSTAND THAT WITHOUT THIS PROVISION, YOU WOULD HAVE THE RIGHT TO SUE IN COURT AND HAVE A JURY TRIAL.
The arbitration shall be commenced and conducted under the Commercial Arbitration Rules of the American Arbitration Association ("AAA") and, where appropriate, the AAA’s Supplementary Procedures for Consumer Related Disputes ("AAA Consumer Rules"), both of which are available at the AAA website www.adr.org.
Your arbitration fees and your share of arbitrator compensation shall be governed by the AAA Consumer Rules and, where appropriate, limited by the AAA Consumer Rules.
The arbitration may be conducted in person, through the submission of documents, by phone, or online. The arbitrator will make a decision in writing, but need not provide a statement of reasons unless requested by either Party. The arbitrator must follow applicable law, and any award may be challenged if the arbitrator fails to do so. Except where otherwise required by the applicable AAA rules or applicable law, the arbitration will take place in Wake County in North Carolina.
Except as otherwise provided herein, the Parties may litigate in court to compel arbitration, stay proceedings pending arbitration, or to confirm, modify, vacate, or enter judgment on the award entered by the arbitrator.
If for any reason, a Dispute proceeds in court rather than arbitration, the Dispute shall be commenced or prosecuted in the state and federal courts located in Wake County, North Carolina, and the Parties hereby consent to, and waive all defenses of lack of personal jurisdiction, and forum non conveniens with respect to venue and jurisdiction in such state and federal courts.
Application of the United Nations Convention on Contracts for the International Sale of Goods and the Uniform Computer Information Transaction Act (UCITA) are excluded from these Terms of Use.
In no event shall any Dispute brought by either Party related in any way to the Service be commenced more than one (1) year after the cause of action arose. If this provision is found to be illegal or unenforceable, then neither Party will elect to arbitrate any Dispute falling within that portion of this provision found to be illegal or unenforceable and such Dispute shall be decided by a court of competent jurisdiction within the courts listed for jurisdiction above, and the Parties agree to submit to the personal jurisdiction of that court.
