Williamson Pickett Gross 116 John Street New York NY 10.038 Attention: Mr. David George - Chief Building Engineer

Regarding: Air Quality Testing

Dear Mr. George:

Please find attached analysis results for air samples collected at 116 John Street on Saturday October 13, 2001. The samples were collected from five locations each on floors 4. 8, 16, 20 and 29.

The samples and two blank cassettes were submitted to Scientific Laboratories, Inc. (ELAP# 11480) for analysis using phase contrast microscopy (PCM). The federal EPA action level for asbestos fiber exposure in the Work place is 0.01 Fibers/cubic centimeter of air. The results indicate that the ambient fiber concentrations at the time of sampling were well below this limit.

If there are any questions regarding the attached results or the methodologies employed, please do not hesitate to contact this office.

Best regards,

Pet El ems ( sident :
