order of a court or other governmental body having jurisdiction or (ii) is otherwise required by applicable law or regulation, provided in either case that Receiving Party uses best efforts to limit the scope of the disclosure to that which is
required, provides Disclosing Party with prior written notice of such requirement as soon as reasonably possible, and cooperates with Disclosing Party in seeking a protective order, confidential treatment, or similar remedy limiting the use and
