In this deposition a representative of EXXON admits knowedge of asbestos dangers back to 1937 and its failure to warn for decades thereafter. Rather than my editorializing, I encourage you to read the deposition yourself which can be found at http://www.mesotheliomalegalblog.com/mesothelioma-litigation/Exxon-Admits-Knowledge-of-Asbestos-Hazards-&-Failure-to-Warn–1-33468.html
