14. Governing Law, Jurisdiction, and Dispute Resolution

14.1 Governing Law

These Terms and any dispute arising out of or relating to these Terms or the Service shall be governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict of law provisions.

14.2 Binding Arbitration

PLEASE READ THIS SECTION CAREFULLY — IT AFFECTS YOUR LEGAL RIGHTS.

Any dispute, claim, or controversy arising out of or relating to these Terms or the breach, termination, enforcement, interpretation, or validity thereof, including the determination of the scope or applicability of this agreement to arbitrate, shall be determined by binding arbitration administered by the American Arbitration Association ("AAA") under its Commercial Arbitration Rules. The arbitration shall be conducted by a single arbitrator. The place of arbitration shall be Wilmington, Delaware, or may be conducted remotely at the arbitrator's discretion. The language of the arbitration shall be English.

The arbitrator shall have the authority to award any remedy or relief that a court of competent jurisdiction could order, provided that the arbitrator may not award relief in excess of what these Terms permit. The arbitrator's decision shall be final and binding. Judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof.

Each party shall bear its own costs and attorneys' fees in any arbitration proceeding, unless the arbitrator determines that a party's claim or defense was frivolous, in which case the arbitrator may award attorneys' fees to the prevailing party.

14.3 Exceptions to Arbitration

Notwithstanding the above, either party may seek injunctive or other equitable relief in any court of competent jurisdiction to prevent the actual or threatened infringement, misappropriation, or violation of intellectual property rights, confidentiality obligations, or unauthorized access to the Service. Additionally, either party may bring claims in small claims court if the claim qualifies.

15. Class Action Waiver

YOU AND TETHER AGREE THAT EACH PARTY MAY ONLY BRING CLAIMS AGAINST THE OTHER IN YOUR OR ITS INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. UNLESS BOTH YOU AND TETHER AGREE OTHERWISE, THE ARBITRATOR MAY NOT CONSOLIDATE OR JOIN MORE THAN ONE PERSON'S OR PARTY'S CLAIMS AND MAY NOT OTHERWISE PRESIDE OVER ANY FORM OF A CONSOLIDATED, REPRESENTATIVE, OR CLASS PROCEEDING. IF THIS CLASS ACTION WAIVER IS FOUND TO BE UNENFORCEABLE, THEN THE ENTIRETY OF THE ARBITRATION PROVISION IN SECTION 14 SHALL BE NULL AND VOID, AND THE DISPUTE SHALL BE SUBMITTED TO THE EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS LOCATED IN WILMINGTON, DELAWARE.
