ENCR VIA FACSIMILE June 10, 1994 ENSR Consulting and Engineering 1320 Harbor Bav Parkwav Alameda, CA 94501 (510) 865-1888 (510) 748-6799 (FAX) Hasmukh C. Shah, Ph.D. Manager Vinyl Chloride Panel Chemical Manufacturing Association 2501 M Street, NW Washington, DC 20037 Dear Dr. Shah: As we discussed earlier this week, I am leaving ENSR and going to establish my own medical practice and consulting business. As you may remember, in 1988, ENSR purchased Environmental Health Associates (EHA). I was one of the three owners of EHA. ENSR made this acquisition in order to combine medical and epidemiology consulting with ENSR's core environmental services business. ENSR, like many organizations, has determined that it should focus on it core business and has concluded an agreement with me to spin off the remaining medical and epidemiological business. I will establish my own medical practice and consulting business and will be moving to new offices in July. Until that time, 1 can be reached at ENSR. Otto Wong and I look forward to being able to provide CMA with the same epidemiological services that we had provided through EHA and ENSR. ENSR does not wish to retain the medical or epidemiological type of business. I believe that I can provide more personal services as an independent organization. In regards to storage of the 100 or so banker boxes containing data from the previous CMA Vinyl Chloride study, the monthly charge from ENSR is $35.00. There are additional charges for retrieval of boxes. ENSR will keep these files until CMA decides what it wishes to do. If you have any questions about our previous agreement/contract, please call me or Christian Seigneur, General Manager of ENSR's Alameda Office.
