12.6 Force Majeure - Neither Licensor nor Licensee shall be in default of the terms of this Agreement because the party delays performance or fails to perform such terms; provided such delay or failure is not the result of the party’s intentional or negligent acts or omissions, but the result of causes beyond the reasonable control of such party (any such cause is a “Force Majeure Event”). Causes reasonably beyond the control of Licensor and Licensee shall include, but not be limited to, revolutions; civil disobedience; fires; acts of God, war, or public enemies; blockades; embargoes; strikes; labour disputes; governmental, administrative or judicial orders, delays in transit or deliveries.
