It shall not be a breach or default under this Ordinance if either party fails to perform its obligations hereunder due to force majeure. Force majeure shall include, but not be limited to, the following: 1) physical events such as acts of God, landslides, lightning, earthquakes, fires, freezing, storms, floods, washouts, explosions, breakage or accident or necessity of repairs to machinery, equipment or distribution or transmission lines; 2) acts of others such as strikes, work-force stoppages, riots, sabotage, insurrections or wars; 3) governmental actions such as necessity for compliance with any court order, law, statute, ordinance, executive order, or regulation promulgated by a governmental authority having jurisdiction; and (4) any other causes, whether of the kind herein enumerated or otherwise not reasonably within the control of the affected party to prevent or overcome. Each party shall make reasonable efforts to avoid force majeure and to resolve such event as promptly as reasonably possible once it occurs in order to resume performance of its obligations hereunder; provided, however, that this provision shall not obligate a party to settle any labor strike.
