100 Fields <LOD = Less than limit of detection which is 5.5 Fibers/ Sample Analysis by: VOIDI = H.C.P. ( High Concentration of Particles) Positive Phase Contrast Microscopy (PCM) VOID2 = Overloaded

Method of Sample Preparation and Analysis: August 1994 NIOSH 7400 Method using "A" Counting Rules. Issue 2, All samples analyzed in accordance with the Instrumentation: m a I a Graticule (100um field diameter). Laboratory Director Olympus PCM Model BH-2 with Walton-Beckett Report Date: October 30, 2001 7400. Among other limitations, this meth within the limitations of the method described as NIOSH JLC is responsible for only the fiber counts asbestos concentration. Any and all claims arising out of JLC's analyst provides only an estimate of gives only an index of airborne fibers and liability and the client agrees to seek no costs b of analyzing samples. JLC accepts no other these samples are limited in recovery to the cost the above. Page 1 of 2
