claims shall never exceed; a total of ten times the annual management fee payable hereunder.  (ii)
Notwithstanding anything that may appear to the contrary in this Agreement, the Managers shall not be liable for any of the actions of the Crew, even if such actions are negligent, grossly negligent or wilful, except

would be liable under sub-clause 11.2, the Owners hereby undertake to keep the Managers and their employees, agents and sub-contractors indemnified and to hold them harmless against all actions, proceedings, claims, demands or liabilities whatsoever
