against all claims, demands and causes of action of every kind and character arising from pollution or contamination, which originates above the surface of the land or water from spills of fuels, lubricants, motor oil, pipe dope, paints, solvents,

 (b) Operator shall assume all responsibility for, including control and removal of, and shall protect, defend and indemnify Contractor and its

results in pollution or contamination for which either Contractor and Operator, for whom such party is performing work, is held to be legally liable, the responsibility therefore shall be considered, as between Contractor and Operator, to be the
same as if the party for whom the work was performed had performed the same and all of the obligations respecting protection, defense, indemnity and limitation of responsibility and liability, as set forth in (a) and (b) above, shall be specifically
applied.
