10.1    If performance of the Company’s obligations is delayed or hindered by a Force Majeure event it will as soon as reasonably practicable notify the Customer of the reasons for the delay or hindrance.  Failure to give notice will not prevent the Company relying on Condition 10.2 and it will incur no liability for such failure.
