6.2

Any dispute, controversy, difference or claim arising out of or relating to this letter (including the existence, interpretation, performance, breach, termination, or validity thereof or any dispute regarding pre-contractual, contractual or non-contractual obligations arising out of or relating to it) (each, a “Dispute”) shall be resolved through consultation between the parties.
