The PLM sample results were all non-detect for asbestos or less than 1% asbestos.

In addition, Hillmann conducted air sampling in the building in multiple areas on the first floor and on the 2'"~ and 36th floor of the hotels.

The initial air samples collected in the area of Roy's Restaurant analyzed using PCM indicated possible asbestos fibers in exceedence of the levels considered acceptable for occupancy by the NYC DEP. Given the quantity of dust and debris in this area, samples were randomly chosen from this sample pool and analyzed using TEM. Based on the results of these sample results, Roy's Restaurant and associated kitchen were cleaned under containment by a licensed asbestos contractor.

Hillmann advised the owner based on the results of the remaining air and dust samples obtained from the hotel, that no further clean-up under containment was required. EDS proceeded with the clean-up of the interior of the hotel including, Hepa vacuum all horizontal and vertical surfaces, wet wipe horizontal surfaces with appropriate cleaners, wet clean with extraction equipment/method upholstered items and carpet and clean and sanitize bathroom fixtures.

The owner then contracted with Accredited Environmental Technologies ("AET") to develop and implement an air quality management program. AET conducted air sampling and analysis in various areas of the hotel through December 19.

Upon receipt of Hillmann's report, it shall be submitted to the NYC DEP as requested. Please feel free to call Carolyn Bailey of Claris Services Corporation concerning any questions you may have concerning this letter or the actions taken.

Sincerely,
