Accordingly, neither you nor Deepbook may start a formal arbitration proceeding for at least sixty (60) days after one party notifies the other party of a claim in writing.

b. Mandatory Arbitration of Disputes. If a dispute arises out of or relates to this Agreement, or the breach thereof, and the dispute cannot be settled through negotiation, then the dispute shall be finally resolved by binding arbitration administered by the BVI International Arbitration Centre in accordance with the Arbitration Rules of the BVI International Arbitration Centre for the time being in force, which rules are deemed to be incorporated by reference in this Section. The seat of arbitration shall be in the BVI. The tribunal shall consist of 1 arbitrator. The language of arbitration shall be English. If any proceeding is brought for the enforcement of this Agreement, then the successful or prevailing Party shall be entitled to recover attorneys’ fees and other costs incurred in such proceeding in addition to any other relief to which it may be entitled.  You and we each waive any right to assert the doctrine of forum non conveniens, to assert that you or we are not subject to the jurisdiction of such arbitration or courts or to object to venue to the extent any proceeding is brough in accordance herewith. This arbitration provision shall survive termination of these Terms.

Further, if the parties’ Dispute is resolved through arbitration, the arbitrator may not consolidate another person’s claims with your claims, and may not otherwise preside over any form of a representative or class proceeding. If this specific provision is found to be unenforceable, then the entirety of this Dispute Resolution section shall be null and void.
