Wolkodoff - R&D Ctr Copies: Subject: DETERMINATION OF CHRYSOTILE BY TEM IN COMMERCIAL TALCS 1. Fourteen commercial talcs were examined by TEM for the presence of chrysotile. The samples are identified in Table NO. 1, which also lists individual TEM plate num bers. .2 The presence or absence of chrysotile is based on scanning from 20 to 25 fields for each sample. Three electron micrographs were taken of typical fields in each sample. These electron micrographs, a total of 42 prints, are attached. ": 3, The results are listed in Table No. 2. If chrysotile was detected in a sample, a percentage is listed and, at best, is qualitative. However, these percentages are relative to each other. Data on tremolite or tremolite-like amphibole are also listed but are based mainly on qualitative petrographic work as a frame of reference for future optical work by recent FDA proposal. Results: A. Chrysotile was not detected in: Mistron Vapor Mistron Monomix Pfizer Emtal 599 Cyclo-Fil B. If the chrysotile content was determined to be 1000 ppm or less, the chrysotile at this stage of the study has to be considered a contaminant. These include : Yellowstone Mistron Super Frost Johnson and Johnson, Vermont Cyclo-Sorb Johnson and Johnson Baby Powder PLAINT fFFS EXHIBIT CAM-266 CRMC-Talc-Micro-001371 "V m Page 2 R. S. Lamar August 28, 1973 C. The only samples which contain chrysotile believed to be part of the mineralogical system at this stage of the study arei Fibrene 0400 Asbestine 5X Nytal 300 Italian Cosmetic Talc 5. In many of the electron micrographs, distinctly fibrous material appears, even though chrysotile and tremolite are not reported. These "fibers" are talc verified, either during process of scanning or by reviewing TEM plates under a binocular microscope. \J. '. V. E. wolkodoff jmw Attachment cc: J. M. Sharratt 2 West w. L.

Unlike chrysotile, tremolite has no particular distinguishing feature other than morphological in some cases when examined by TEM.

Baumgardner, being o f full age and first duly sworn do hereby state: 1. Iam not a party to this action. I have personal knowledge o f the facts set forth in this affidavit, and if called as a witness, I could and would competently testify as to the truth of the matters set forth herein. 2. Ia m the Research Coordinator for the Claims Resolution Management Corporation ("CRMC"), a wholly owned subsidiary o f the Manville Personal Injury Settlement Trust ("Trust"). The CRMC was created in December 1998 and is staffed by former Trust employees. On January 1, 1999, CRMC began providing claims resolution facility services to the Trust. 3. In this position, I manage the Asbestos Claims Research Facility ("Facility"), a document and records repository located at 3390 Peoria Street, Suite 304, Aurora, Colorado. The Facility contains the business records including but not limited to correspondence, memoranda, reports, records and data compilations ("record") o f Manville Corporation or related entities ("Manville"), generally, as well as Manville records relevant to litigation o f asbestos liability. The records found at the Facility were transferred from Manville to the Trust beginning in November 28, 1988, the date on which the Manville bankruptcy plan was consummated. Additional records have been and continue to be transferred directly to the Facility. The Facility's records have been in the custody and control of counsel for the Trust or Trust personnel since the date of consummation. 4. My experience and familiarity with the documents at the Facility began in 1983 while working for Manville. In my work as a paralegal for Manville, I assisted in locating, indexing and packing many o f the records which became the foundation documents for the Facility. I continued to work for Manville until September 1987. From March 1988 to September 1 9 8 8 ,1 was hired to supervise and assist in the indexing o f the first 20,000 boxes which were turned over to the Trust in November 1988. From September 1988 to January 1989, I assisted in the privilege review of documents to be given to the Trust. From November 1988 to April 1994,1worked for Freeborn & Peters and was put in charge o f the Facility, managing all productions and "new" acquisitions. In September 1995,1was hired by the Trust to manage the Facility. In December 1998,1was hired by Affidavit o f Margaret J. Baumgardner Page 1 the CRMC to manage the Facility for the Trust. Accordingly, Iam personally familiar with many of the records stored at the Facility, as well as how the records have been gathered. 5. To the best of my knowledge, information and belief, or from information transmitted by a person with knowledge, I certify that these records were made at or near the date they are identified, were kept in the course o f the regularly conducted business activity o f Manville, and it was the regular practice and the business activity o f Manville to make the records. 6. Attached are documents found among the microfilm collections at the Facility. These documents, bates labeled CRMC-Talc-Micro-000001 through CRMC-Tulc-Micro-005259, are true and correct copies of documents found at the Facility.
