If a Force Majeure (such as war, nuclear or chemical contamination or pressure waves caused by supersonic devices) occurs which causes either party to be unable to comply with its obligations then as detailed in paragraph 22.4, the party effected by the Force Majeure will be relieved of its obligations. The parties must then try to reach agreement on any variations required to the Contract which may be equitable having regard to the Force Majeure. If the parties fail to reach such agreement, within 6 months, the Contract may be terminated by either party (provided that the Force Majeure is still subsisting and is preventing them from performing their material obligations).
