If the part in quotes: "reasonable steps", isn't in the contract, what is?
The conditions involving the sale of London-based Peninsular and Oriental Steam Navigation Co. were detailed in U.S. documents marked "confidential." Such records are regularly guarded as trade secrets, and it is highly unusual for them to be made public.
Again, I don't know the context, but generally I find it quite reasonable for a company to have a clause saying "all reasonable steps" when discussing assisting a government entity in performing its duty.
