In the event that such protective order or other remedy is not sought or obtained within a reasonable time under the circumstances, the notifying Party may furnish only that portion of the information which it is legally compelled to disclose or advised by legal counsel to disclose and will use its commercially reasonable efforts to obtain reliable assurance that confidential treatment will be accorded any information so furnished. 5.4 ADDITIONAL COVENANTS.
