12.1 AChA shall not be liable for any failure or delay in performing its obligations under an Event agreement where such failure or delay is caused by circumstances beyond its reasonable control, including but not limited to acts of God, war, terrorism, civil unrest, government restrictions, epidemics, pandemics, natural disasters, or other similar events ("Force Majeure Event"). In such cases, AChA reserves the right to postpone or cancel the Event without liability for ancillary costs, and refunds will be handled as per clause 11.
