assess the toxicity of the test material, N-Methyl Perfluorooctanesulfonamido Ethanol (N-MeFOSE, T-6314) when administered in the diet to rats for at least 13 weeks. Four groups o f Crl:CD(SD) IGS BR rats were exposed to N-MeFOSE in the diet for at least 13 weeks. Each group contained 20 males and 20 females. The dietary concentrations were 0 (control group), 3, 30, and 100 ppm. Food was provided ad libitum, except when animals were fasted. Water was provided ad libitum. The animals were observed twice daily (a.m. and p.m.) for mortality and moribundity. At least once weekly, each animal was removed from its cage and examined for abnormalities and signs o f toxicity. Body weight data were collected on the first day o f treatment and weekly thereafter. Food consumption data were collected weekly. Ophthalmic examinations were done before initiation o f treatment and during Week 14. Blood samples were collected for hematology and clinical chemistry tests during Weeks 5 and 14. Urine samples for urinalysis tests were collected during W eek 14. During Weeks 5 and 14, blood was collected from five animals/sex/group for serum perfluorooctane sulfonic acid (PFOS) analyses. At the Week 5 sacrifice, samples o f the liver were collected from five animals/sex/group for palmitoyl-CoA oxidase activity and liver PFOS analysis. Animals sacrificed at Week 5 were not necropsied. During Week 14, the remaining animals were anesthetized, weighed, exsanguinated, and necropsied. At necropsy, macroscopic observations were recorded, selected organs were weighed, and selected tissues were collected and preserved. Samples o f liver were collected from all surviving animals for palmitoyl-CoA oxidase activity and liver PFOS analysis. Samples of the liver were collected from five animals/sex/group for proliferation cell nuclear antigen (PCNA) evaluation and microscopic examination. Microscopic examinations were done on tissues from each animal in the control and high-dose groups (terminal sacrifice only) and from the low-dose animal that was sacrificed at an unscheduled interval. Microscopic examinations were also done on the liver and stomach from each terminal sacrifice animal in the mid-dose group, and on the liver from each terminal sacrifice animal in the low-dose group. 8 OOOOll Covance 6329-225 3M T-6314.1 One female given 3 ppm N-MeFOSE was sacrificed on Day 59 due to severe laceration of the tail. There were no macroscopic or microscopic changes to indicate that its moribund condition was test material-related. All other animals survived to the scheduled sacrifice. No clinical observations were noted that were considered to represent primary effects of the test material. Statistically significantly lower mean body weights were noted beginning at W eek 4 and continuing through the end o f study for animals given 100 ppm. Statistically significantly lower mean body weights were noted beginning at Week 7 and continuing through the end of study for males given 30 ppm. Body weight changes were statistically significantly lower in a sporadic manner for animals given 30 or 100 ppm Overall body weight changes (Weeks 1-14) were statistically significantly lower for all groups given N-MeFOSE. Although statistically significant only at W eek 13, food consumption was in general lower for males given 100 ppm For females given 100 ppm, statistically lower food consumption was apparent at Weeks 3, 4, 6, 7, 11, and 12. Dietary administration of N-MeFOSE was associated with lower hematocrit for males and females fed 100 p p m higher urea nitrogen for males and females fed 100 ppm; higher albumin for males fed 100 ppm; lower globulin for males fed 30 or 100 ppm; lower cholesterol and triglycerides for males fed 30 or 100 ppm and females fed 100 ppm; higher alanine aminotransferase for males fed 100 ppm; and higher hepatic palmitoyl CoA oxidase for males and females fed 100 p p m The effects were relatively mild with the exception o f those on cholesterol and triglycerides for the high-dose males; those effects were considered to be of moderate severity. All o f the test material-related clinical pathology findings were more prominent at Week 14 than at Week 5. Statistically significant and test material-related changes in terminal body weights and liver weights were seen in males and/or females in the two highest dose groups. Statistically significant decreases were seen in the terminal body weights o f males fed 30 ppm and in both males and females fed 100 ppm o f N-MeFOSE. Statistically significant increases were seen in the mean liver-to-body weight percentage and mean liver-to-brain weight ratio in males fed 30 p p m in mean absolute liver weight and mean liver-to-body weight percentage in females fed 30 ppm and in all liver weight parameters in males and females fed 100 ppm 9 000012 Covance 6329-225 3M T-6314.1 Test material-related macroscopic findings were noted at a low incidence in the liver and glandular stomach o f males and females in the 100 ppm dose group only. Liver findings included organs that were large and diffusely dark. In the glandular stomach, dark foci or areas were sometimes seen in the gastric mucosa. Test material-related microscopic findings were seen in the liver o f animals fed 30 and 100 ppm of N-MeFOSE and in the glandular stomach o f males and females in the 100 ppm group only. No test material-related changes were seen in animals fed 3 ppm of N-MeFOSE. In the liver, one or more test material-related findings affected all animals fed 100 ppm and included slight-to-moderate centrilobular or diffuse hepatocellular hypertrophy, minimal-to-slight coagulative necrosis, minimal hepatocellular pigment, and minimal-to-slight centrilobular to midzonal or diffuse hepatocellular vacuolation. In animals fed 30 ppm, centrilobular hepatocellular hypertrophy was also seen, although the incidence and severity was decreased at this dose. In addition, a low incidence o f minimal hepatocellular vacuolation occurred in 30 ppm dose group males, and the liver of a single female fed 30 ppm had minimal coagulative necrosis. A possible test material-related change in the glandular stomach of animals fed 100 ppm was a relatively low incidence of mucosal erosions. The erosions were o f minimal to slight severity and involved a very small portion o f the mucosal surface in all cases. Based on anatomic pathology, clinical pathology, and body weight effects at 30 and 100 ppm the no-observable-adverse-effect level was determined to be less than 30 ppm when N-MeFOSE is administered at concentrations of 0, 3, 30 and 100 ppm to Crl:CD(SD) IGS BR rats for at least 13 weeks through dietary administration. Based on the body weight effects at 3, 30, and 100 ppm, the no-observable-effect level was determined to be less than 3 ppm when N-MeFOSE is administered at concentrations of 0, 3, 30 and 100 ppm to Crl:CD (SD) IGS BR rats for at least 13 weeks through dietary administration. In the absence o f correlative changes in anatomic pathology and clinical pathology the body weights effects at 3 ppm were not considered to be biologically adverse. 10 000013 PURPOSE Covance 6329-225 3M T-6314.1 TTie purpose of this study was to assess the toxicity o f the test material, N-Methyl Perfluorooctanesulfonamido Ethanol (N-MeFOSE, T-6314) when administered in the diet to rats for at least 13 weeks. REGULATORY COMPLIANCE All aspects o f this study were in accordance with the Food and Drug Administration Good Laboratory Practice Regulations as set forth in Title 21 o f the US Code o f Federal Regulations, Part 58, issued December 22, 1978 (effective June 20, 1979), and with any applicable amendments. TEST MATERIAL Test Material The test material, N-Methyl Perfluorooctanesulfonamido Ethanol (MeFOSE, T-6314), Lot No. F -l 1364, is an off white powder. It was received at Covance on August 3, 1995. The test material was stored at room temperature. Information on synthesis methods, stability, purity, composition, or other characteristics that define the test material is on file with the Sponsor. Reserve (Archive) Sample A reserve sample (approximately 5 g) of the test material was taken and stored at room temperature. This sample will be transferred to the Sponsor after authorization from the Sponsor. Disposition Remaining test material will be returned after authorization from the Sponsor. 11 000014 ANIMALS AND HUSBANDRY Covance 6329-225 3M T-6314.1 Test Animal Male and female Crl:CD(SD) IGS BR rats were obtained from the Portage, Michigan, facility o f Charles River Laboratories, Inc., on August 17, 1998. The animals were 39 to 45 days old at initiation of treatment. The males weighed from 184 to 236 g, and the females weighed from 140 to 179 g at initiation of treatment. Identification Each animal was assigned a temporary number upon arrival. Before initiation of treatment, a microchip identification device was implanted into each animal. After randomization for placement on test, each animal was assigned a permanent number, and the microchip was coded with that number. All data for an animal are recorded under these numbers. Acclimation Ninety-two males and 92 females were received on August 17, 1998, and acclimated in Animal Room 348 for 15 days before initiation o f treatment. In general, animals in this shipment appeared healthy. During acclimation, the animals were examined for abnormalities indicative of health problems, an ophthalmic examination was done, and body weights were recorded for all animals at randomization. Housing and Maintenance Animal Room 348 was used for this study. Environmental controls for the animal room were set to maintain 18 to 26C, a relative humidity o f 30 to 70%, and a 12-hour light/12-hour dark cycle. The animals were housed individually (except for the first 7 days of acclimation when animals were group-housed) in stainless steel, screen-bottom cages. 12 000015 Covance 6329-225 3M T-6314.1 Certified rodent diet #5002 meal, (PMI Nutrition International) was provided (see Protocol Deviations for exceptions) ad libitum, except when animals were fasted. The diet is routinely analyzed by the manufacturer for nutritional components and environmental contaminants. The results are on file with Covance-Madison. W ater was provided ad libitum. Samples of the water are routinely analyzed for specified microorganisms and environmental contaminants. The results are on file with Covance-Madison. There were no known contaminants in the diet or water at levels that would have interfered with this study. Animals not selected for the study (12 males and 12 females) were removed from the study room and used for training procedures. Justification Historically rats have been used in safety evaluation studies and are recommended by appropriate regulatory agencies. PROCEDURES This study was conducted in accordance with the Protocol dated August 27, 1998, and Protocol Amendment Nos. 1, 2, and 3. The protocol, protocol amendments, and protocol deviations are in Appendix 1. Group Designations and Dose Levels The animals were examined by a laboratory animal veterinarian on August 31, 1998, and found to be suitable for study consideration. Selection o f animals for the study was based on clinical observations, body weights, ophthalmic examinations, and other data as appropriate. Animals were assigned to treatment groups using a computerized blocking procedure designed to achieve body weight balance with respect to treatment group. At the time o f randomization, the weight variation o f the animals for each sex used did not 13 000016 Covance 6329-225 3M T-6314.1 exceed 2 standard deviations of the mean weight. Group mean body weights were analyzed using Levene's test for homogeneity of variance at the 5.0% probability level and found to be homogeneous. Animals were assigned to the study according to the following design: Number of Animals Dietary Levels Group Male Female (ppm MeFOSE)3 1 (Control)b 20 20 0 2 (Low) 20 20 3 3 (Mid) 20 20 30 4 (High) 20 20 100 a Dose levels were expressed as ppm o f MeFOSE. b The control animals received the basal diet only. Dose Preparation Dietary concentrations were based on the test material as supplied. Before initiation of treatment, diets o f 1, 3, 30, 100, and 500 ppm concentrations were mixed. Diets were prepared for stability analyses at the 1-ppm and 500-ppm concentrations and for homogeneity analyses at the 3, 30, and 100 ppm concentrations. Diets were prepared once every 4 weeks for use in the in-life phase. Preparation of Diet for Group 1. The appropriate amount o f diet was weighed into a labeled container and acetone was added at the same concentration as the high-dose concentration. The combination o f the diet and acetone was then mixed for 15 minutes. Preparation of Diets for Groups 2 through 3. Each dose level was prepared independently. A specified amount of diet was weighed into a labeled container and a specified amount o f diet for Group 4 was weighed for each diet. A trench was formed in the feed in the mixing bowl and the amount of diet for Group 4 was transferred to the trench. The contents o f the mixing bowl were thoroughly mixed for 15 minutes. Preparation of Diet for Group 4. A specified amount of diet was weighed into a labeled container. The required amount o f test material was weighed and transferred into a labeled container. Approximately 5 mL of acetone was added to the container and mixed manually. Increments o f approximately 5 mL acetone were added as necessary until the test material had dissolved. To prepare a premix, the diet was transferred into a labeled 14 000017 Covance 6329-225 3M T-6314.1 Hobart mixing bowl. The test material and acetone were added to the mixing bowl, overlaid with a portion of diet from the mixing bowl, and thoroughly mixed. A portion of diet from the mixing bowl was transferred to a second mixing bowl, mixed manually to recover residual test material, and returned to the first mixing bowl. The contents o f the mixing bowl were thoroughly mixed. Samples for dose analyses were taken directly from the mixing bowl. The prepared test diets were stored at room temperature in covered containers until dispensed into feeding jars. Retention Samples During the in-life phase, samples (approximately 100 g) were taken from each dose preparation for dose analyses and stored at room temperature. These samples were discarded on May 11, 1999 (see Protocol Deviations for exceptions). Method of Administration Dietary admixture was used because the potential route o f exposure in humans is oral. The dose preparations were administered ad libitum for at least 13 weeks, unless otherwise specified. Dose Analyses Analyses for the concentration o f test material in the dose preparations were done by Covance using an analytical method, MP-M324-MA, supplied by the Sponsor and validated by Covance. Homogeneity was determined for the 3-ppm, 30-ppm, and 100-ppm dose preparations once pretest. One sample (approximately 100 g) each from the top, middle, and bottom of the dose preparations mixed for homogeneity analyses were collected, divided into three subsamples for extraction and analysis, and analyzed for test material content. All samples were stored at room temperature until analyzed within 7 days o f mixing. 15 000018 Covance 6329-225 3M T-6314.1 Four samples (approximately 100 g each) were taken from the 1-ppm dose level concentration o f diet preparations mixed pretest. One sample was analyzed on the day of mixing and used as the baseline value. One sample was stored at room temperature for at least 19 days, then analyzed. A third sample was stored at room temperature for at least 32 days, then analyzed. The remaining sample was stored in a freezer set to maintain -10 to -30C for 8 weeks, then analyzed. In addition, two samples (approximately 100 g each) were taken from the 500-ppm dose preparation mixed pretest. One sample was analyzed on the day of mixing. The second sample was stored at room temperature after at least 32 days, then analyzed. Two additional samples (approximately 100 g each) were taken from the 3-ppm dose preparation mixed for Weeks 9 through 12. One sample was stored at room temperature for at least 19 days, then analyzed. The second sample was stored at room temperature for at least 32 days, then analyzed. The sample collected for dose confirmation analysis was used as the baseline sample. During the in-life phase, samples (approximately 100 g) from all dose preparations were collected and analyzed for dose confirmation. All samples were stored at room temperature until analyzed. Clinical Observations The animals were observed twice daily (a.m. and p.m.) for mortality and moribundity (see Protocol Deviations for exceptions). Signs of poor health or abnormal behavior were recorded as they were observed. At least once weekly, each animal was removed from its cage and examined. Any unusual or abnormal findings were recorded. Body Weights Individual body weight data were recorded on the first day of treatment, and weekly thereafter. Food Consumption Individual food consumption data were recorded weekly during treatment. Food consumption was not measured during Week 5 for animals scheduled for sacrifice during Week 5. 16 000019 Covance 6329-225 3M T-6314.1 Ophthalmology Ophthalmic examinations were done before initiation o f treatment and during W eek 14. The pupils were dilated with 0.5% Mydriacyl, and the eyes were examined by a veterinarian with an indirect ophthalmoscope. Clinical Pathology Blood samples were collected from 10 animals/sex/group during Weeks 5 and 14. Urine samples were collected from 10 animals/sex/group during Week 14. Animals were fasted overnight, (see Protocol Deviations for exception) and urine was collected chilled (approximately 16 hours before blood sampling); water was provided ad libitum. Blood was collected from a jugular vein. Potassium EDTA was used as the anticoagulant for hematology tests. No anticoagulant was used for the clinical chemistry samples. Animals were bled in random order. The following were evaluated: Hematology red blood cell (erythrocyte) count hemoglobin white blood cell (leukocyte) count differential blood cell count hematocrit segmented neutrophil count mean corpuscular volume mean corpuscular hemoglobin lymphocyte count monocyte count mean corpuscular hemoglobin concentration platelet count eosinophil count basophil count blood cell morphology Reticulocyte count smears were made and held for possible future examination. glucose urea nitrogen creatinine total protein albumin globulin total bilirubin cholesterol triglycerides Clinical Chemistry aspartate aminotransferase alanine aminotransferase gamma glutamyltransferase calcium inorganic phosphorus sodium potassium chloride 17 000020 volume specific gravity PH protein glucose ketones Covance 6329-225 3M T-6314.1 Urinalysis bilirubin blood urobilinogen microscopic examination of sediment appearance Serum Perfluorooctane Sulfonic Acid Level (PFOS) Determination During W eeks 5 and 14, five animals/sex/group were fasted overnight, (see Protocol Deviations for exception) anesthetized with carbon dioxide, and blood (approximately 4 mL) was collected from a jugular vein. All samples were collected without anticoagulant, allowed to clot at room temperature, and centrifuged. Serum was harvested and stored in a freezer set to maintain -60 to -80C until packed on dry ice and shipped to the Sponsor for analyses. The samples were analyzed for PFOS. Results of analyses will be reported separately by the Sponsor. Necropsy A necropsy was done on the Group 2 female that was sacrificed at an unscheduled interval. During Week 5, five animals/sex/group were fasted overnight (see Protocol Deviations for exception), anesthetized with carbon dioxide, bled for serum PFOS samples, weighed, and exsanguinated. These animals were discarded without necropsy. The liver was removed from these animals, weighed, and collected for palmitoyl CoA oxidase and PFOS analysis. During Week 14, the remaining animals were fasted overnight, anesthetized with carbon dioxide, bled for clinical pathology tests (10 animals/sex/group with the exception of Group 2 female) and serum PFOS samples (five animals/sex/group), weighed, exsanguinated, and necropsied. Liver samples were collected for palmitoyl CoA oxidase, PCNA, and PFOS analysis. Animals were necropsied in random order. The necropsy included a macroscopic examination of the external features of the carcass; all external body orifices; the abdominal, thoracic, and cranial cavities; organs; and tissues. 18 000021 Covance 6329-225 3M T-6314.1 Organ Weights After 13 weeks o f treatment, the following organs (when present) were weighed; paired organs were weighed together: a d r e n a l(2) brain kidney (2) liver ovary (2) spleen testis (2) thymus thyroid (2) with parathyroid Organ-to-body weight percentages and organ-to-brain weight ratios were calculated. Cell Proliferation Tissue Collection and Immunohistochemical Evaluation At the terminal sacrifice, representative samples o f the left lateral lobe o f the liver were collected from five animals/sex/group and preserved in zinc formalin. After fixation, samples were embedded in paraffin and shipped to Pathology Associates International (Frederick, Maryland) for proliferation cell nuclear antigen (PCNA) evaluation. In addition, liver sections were stained with hematoxylin and eosin and examined microscopically. Results o f the evaluation are in Appendix 7. Palmitoyl-CoA Oxidase Tissue Collection and Analyses At the scheduled sacrifices, the right lateral lobe of the liver was collected from each animal, flash-frozen in liquid nitrogen, and stored in a freezer set to maintain -60 to -80C until analyzed by Covance for palmitoyl CoA oxidase activity. Liver PFOS Analyses At the scheduled sacrifices, a portion of the liver from each animal was flash-frozen in liquid nitrogen and stored in a freezer set to maintain -60 to -80C until packed on dry ice and shipped to the Sponsor for PFOS and metabolites analyses. Results of these analyses will be reported separately by the Sponsor. 19 000022 Covance 6329-225 3M T-6314.1 Tissue Preservation The following tissues (when present) from the animal that was sacrificed at an unscheduled interval, or from each animal sacrificed at the terminal sacrifice were collected and preserved in 10% neutral-buffered formalin, unless otherwise specified: adrenal (2) aorta brain cecum cervix colon duodenum epididymis (2) esophagus eye (2) femur with bone marrow (articular surface of the distal end) Harderian gland heart ileum with Peyer's patch (lymphoid aggregate) jejunum kidney (2) lesions liver lung with mainstem bronchi lymph nodes (mesenteric and mandibular) mammary glands (females only) ovary (2) pancreas pituitary prostate rectum salivary gland [mandibular (2)] sciatic nerve seminal vesicle (2) skeletal muscle (thigh) skin spinal cord (cervical, mid-thoracic, and lumbar) spleen sternum with bone marrow stomach testis (2) thymus thyroid (2) with parathyroid trachea urinary bladder uterus vagina Zymbal's gland Histopathology Tissues (as appropriate) were embedded in paraffin, sectioned, stained with hematoxylin and eosin, and examined microscopically from each animal in the control and high-dose groups and from the low-dose animal that was sacrificed at an unscheduled interval. Due to microscopic findings noted in the high-dose group, the liver and stomach from animals in the mid-dose group, and the liver from animals in the low-dose group were also embedded in paraffin, sectioned, stained with hematoxylin and eosin, and examined microscopically. 20 000023 Covance 6329-225 3M T-6314.1 Macroscopic lesions from animals in the low- and mid-dose groups were embedded in paraffin, sectioned, stained with hematoxylin and eosin, and examined microscopically. Bone marrow smears from the femur o f each animal were prepared at the scheduled sacrifice after 13 weeks o f treatment, stained with Wright's stain, and retained for possible examination. Statistical Analyses Levene's test (Levene, 1960) was done to test for variance homogeneity. In the case of heterogeneity o f variance at p < 0.05, transformations were used to stabilize the variance. Comparison tests took variance heterogeneity into consideration. One-way analysis of variance [ANOVA (Winer, 1971a)] was used to analyze body weights, body weight changes, food consumption, continuous clinical pathology values; organ weights, organ-to-body weight percentages, and organ-to-brain weight ratios. If the ANOVA was significant, Dunnett's t-test (Dunnett, 1964) was used for control versus treated group comparisons. Group comparisons (Groups 2 through 4 versus Group 1) were evaluated at the 5.0%, two-tailed probability level. Only data collected on or after the first day of treatment was analyzed statistically.

RESULTS Dose Analyses Results o f the homogeneity, stability, and dose preparation analyses are in Tables 1 through 3. Mean values o f the homogeneity analyses ranged from 74.0-78.0%, 84.0-96.7%, and 77.5-84.2% of the theoretical concentrations for the diets containing 3, 30, and 100 ppm N-MeFOSE, respectively. These results indicate that the mixing procedure produced a homogeneous distribution o f the test material in the dose preparations; although variability generally appeared slightly greater at the 3 and 30-ppm dietary concentrations. Results o f stability analyses o f samples stored for 19 and 32 days at room temperature and 8 weeks under frozen conditions indicated that the mean concentrations ranged from 54.4-62.5% o f the initial concentrations o f 1 ppm for diet mixed pretest. Samples stored for 32 days at room temperature indicated that the mean concentration was 98.4% of the initial concentrations o f 500 ppm. Results o f stability analyses o f samples stored for 19 and 32 days at room temperature indicated that the mean concentrations ranged from 93.2-94.0% o f the initial concentrations o f 1 ppm for diet mixed at Week 4. Samples stored for 19 days at room temperature indicated that the mean concentration was 89.0% of the initial concentrations o f 3 ppm The mean concentrations of the dose preparation analyses for all levels ranged from 63.7 to 110.0% of the theoretical concentrations. Inherent variability and lack of sufficient sensitivity at low levels in the analytical method for measuring N-MeFOSE resulted in homogeneity, stability and routine analysis data that were in many cases outside of the standard limits o f +/- 15%. These results will be reevaluated in conjunction with the analytical results from the blood and liver level determinations when they are provided by the sponsor. 22 000025 Covance 6329-225 3M T-6314.1 Clinical Observations and Survival Clinical observations are summarized in Table 4; individual data are in Appendix 2. Individual animal fate data are also in Appendix 2. One female given 3 ppm N-MeFOSE was sacrificed on Day 59 due to severe laceration o f the tail. There were no macroscopic or microscopic changes to indicate that its moribund condition was test material-related. All other animals survived to the scheduled sacrifice. No clinical observations were noted that were considered effects o f the test material. Ophthalmology Ophthalmic observations are summarized in Table 5; individual data are in Appendix 2. The Ophthalmology Report contains a discussion of the data. Animals selected for the study had no lesions at the prestudy examination. No test material-related ophthalmic observations were noted at the W eek 14 examination. Body Weights Body weight and body weight change data are summarized in Tables 6 and 7; individual body weight data are in Appendix 3. Test material-related lower body weights were noted for males given 30 and 100 ppm and for males and females given 100 ppm. Statistically significantly lower mean body weights were noted beginning at Week 4 and continuing through the end of study for males and females given 100 ppm. Statistically significantly lower mean body weights were noted beginning at Week 7 and continuing through the end o f study for males given 30 ppm. Body weight changes were statistically significantly lower in a sporadic manner for males given 30 ppm and for animals of both sexes given 100 ppm. Overall body weight changes (Weeks 1-14) were statistically significantly lower for all groups given N-MeFOSE. Food Consumption Food consumption data are summarized in Table 8; individual data are in Appendix 4. 23 000026 Covance 6329-225 3M T-6314.1 Although statistically significant only at W eek 13 for males given 100 ppm, food consumption was lower for males given 30 and 100 ppm when compared to those of controls for most o f the study. Females given 100 ppm had statistically significantly lower food consumption than those o f controls at Weeks 3, 4, 6, 7, 11, and 12. The overall mean food consumption for females fed the 100-ppm concentration was significantly lower by 17.5% when compared with that of the controls. Test Material Consumption Test material consumption data are summarized in Table 9; individual data are in Appendix 4. Animals were fed diets containing 3, 30, or 100 ppmN-M eFOSE, T-6314. The mean amounts of test material consumed by the animals in these groups were 0.148 to 0.304 mg/kg/day; 1.390 to 3.094 mg/kg/day; and 5.054 to 10.291 mg/kg/day for males, respectively. Values for females were 0.184 to 0.319 mg/kg/day; 2.204 to 3.395; and 6.494 to 10.378, respectively. The overall mean test material consumption for males fed diets containing 3, 30, or 100 ppmN-M eFOSE, T-6314 were 0.203,2.041, and 6.844 mg/kg/day, respectively. The overall mean test material consumption for females fed diets containing 3, 30, or 100 ppm N-MeFOSE, T-6314 were 0.240, 2.588, and 7.702, respectively. Clinical Pathology Hematology, clinical chemistry, and urinalysis data are summarized in Tables 10 through 14; individual data are in Appendix 5. The Pathology Report contains a discussion of the data. Dietary administration of N-MeFOSE was associated with lower hematocrit for males and females fed 100 ppm; higher urea nitrogen for males and females fed 100 ppm; higher albumin for males fed 100 ppm; lower globulin for males fed 30 or 100 ppm; lower cholesterol and triglycerides for males fed 30 o r 100 ppm and females fed 100 ppm; higher alanine aminotransferase for males fed 100 ppm; and higher hepatic palmitoyl CoA oxidase for males and females fed 100 ppm. The effects were relatively mild with the exception o f those on cholesterol and triglycerides for the high-dose males; those effects 24 000027 Covance 6329-225 3M T-6314.1 were considered to be o f moderate severity. All o f the test material-related clinical pathology findings were more prominent at Week 14 than at Week 5.

Cell Proliferation Tissue Collection and Immunohistochemical Evaluation Results o f cell proliferation and immunohistochemical evaluation provided by Pathology Associates International are in Appendix 7. Liver PFOS Determination Results o f fiver PFOS level determination will be reported separately by the Sponsor. Anatomic Pathology Terminal body weights, absolute organ weights, organ-to-body weight percentages, and organ-to-brain weight ratios are summarized in Tables 15 and 16; incidences of macroscopic and microscopic observations are summarized in Tables 17 and 18; the incidence o f severity o f microscopic observations is summarized in Table 19. Individual data are in Appendix 6. The Pathology Report contains a discussion o f the data. Statistically significant and test material-related changes in terminal body weights and fiver weights were seen in males and/or females in the two highest dose groups. Statistically significant decreases were seen in the terminal body weights o f males fed 30 ppm and in both males and females fed 100 ppm of N-MeFOSE. Statistically significant increases were seen in the mean liver-to-body weight percentage and mean fiver-to-brain weight ratio in males fed 30 ppm, in mean absolute liver weight and mean liver-to-body weight percentage in females fed 30 ppm, and in all fiver weight parameters in males and females fed 100 ppm 25 000028 Covance 6329-225 3M T-6314.1 Test material-related macroscopic findings were noted at a low incidence in the liver and glandular stomach o f males and females in the 100 ppm dose group only. Liver findings included organs that were large and diffusely dark. In the glandular stomach, dark foci or areas were sometimes seen in the gastric mucosa. Test material-related microscopic findings were seen in the liver o f animals fed 30 and 100 ppm of N-MeFOSE and in the glandular stomach o f males and females in the 100 ppm group only. No test material-related changes were seen in animals fed 3 ppm of N-MeFOSE. In the liver, one or more test material-related findings affected all animals fed 100 ppm and included shght-to-moderate centrilobular or diffuse hepatocellular hypertrophy, minimal-to-slight coagulative necrosis, minimal hepatocellular pigment, and minimal-to-slight centrilobular to midzonal or diffuse hepatocellular vacuolation. In animals fed 30 ppm, centrilobular hepatocellular hypertrophy was also seen, although the incidence and severity was decreased at this dose. In addition, a low incidence o f minimal hepatocellular vacuolation occurred in 30 ppm dose group males, and the liver o f a single female fed 30 ppm had minimal coagulative necrosis. A possible test material-related change in the glandular stomach of animals fed 100 ppm was a relatively low incidence of mucosal erosions. The erosions were o f minimal to slight severity and involved a very small portion o f the mucosal surface in all cases. CONCLUSIONS Based on anatomic pathology, clinical pathology, and body weight effects at 30 and 100 ppm the no-observable-adverse-effect level was determined to be less than 30 ppm when N-MeFOSE is administered at concentrations of 0, 3, 30 and 100 ppm to Crl:CD(SD) IGS BR rats for at least 13 weeks through dietary administration. Based on the body weight effects at 3, 30, and 100 ppm, the no-observable-effect level was determined to be less than 3 ppm when N-MeFOSE is administered at concentrations of 0, 3, 30 and 100 ppm to Crl:CD(SD) IGS BR rats for at least 13 weeks through dietary administration. In the absence of correlative changes in anatomic pathology and clinical pathology the body weights effects at 3 ppm were not considered to be biologically adverse. 26 000029 SIGNATURES Covance 6329-225 3M T-6314.1 Nii'van Bruce-Konuah Study Coordinator Covance Laboratories Inc.

The test material was administered at dose levels o f 3, 30, and 100 ppm. Dietary administration of N-MeFOSE was associated with lower hematocrit for males and females fed 100 ppm; higher urea nitrogen for males and females fed 100 ppm; higher albumin for males fed 100 ppm; lower globulin for males fed 30 or 100 ppm; lower cholesterol and triglycerides for males fed 30 or 100 ppm and females fed 100 ppm; higher alanine aminotransferase for males fed 100 ppm; and higher hepatic palmitoyl CoA oxidase for males and females fed 100 ppm. The effects were relatively mild with the exception of those on cholesterol and triglycerides for the males fed 100 ppm; those effects were considered to be o f moderate severity. All o f the test material-related clinical pathology findings were more prominent at Week 14 than at Week 5. Statistically significant and test material-related changes in terminal body weights and liver weights were seen in males and/or females in the two highest dose groups. Statistically significant decreases were seen in the terminal body weights o f males fed 30 ppm and in both males and females fed 100 ppm. Statistically significant increases were seen in the mean liver-to-body weight percentage and mean liver-to-brain weight ratio in males fed 30 ppm, in mean absolute liver weight and mean liver-to-body weight percentage in females fed 30 ppm, and in all liver weight parameters in males and females fed 100 ppm. Test material-related macroscopic findings were noted at a low incidence in the liver and glandular stomach of males and females in the 100 ppm dose group only. Liver findings included organs that were large and diffusely dark. In the glandular stomach, dark foci or areas were sometimes seen in the gastric mucosa. Test material-related microscopic findings were seen in the liver o f animals fed 30 and 100 ppm o f N-MeFOSE and in the glandular stomach o f males and females in the 100 ppm group only. No test material-related changes were seen in animals fed 3 ppm of 30 000033 Covance 6329-225 3M T-6314.1 N-MeFOSE. In the liver, one or more test material-related findings affected all animals fed 100 ppm, and included slight-to-moderate centrilobular or diffuse hepatocellular hypertrophy, minimal-to-slight coagulative necrosis, minimal hepatocellular pigment, and minimal-to-slight centrilobular to midzonal or diffuse hepatocellular vacuolation. In animals fed 30 ppm, centrilobular hepatocellular hypertrophy was also seen, although the incidence and severity was decreased at this dose. In addition, a low incidence o f minimal hepatocellular vacuolation occurred in 30 ppm dose group males, and the liver o f a single female fed 30 ppm had minimal coagulative necrosis. A possible test material-related change in the glandular stomach o f animals fed 100 ppm was a relatively low incidence of mucosal erosions. The erosions were o f minimal to slight severity and involved a very small portion of the mucosal surface in all cases. METHODS Four groups of Crl:CD(SD) IGS BR rats (20 animals/sex/group) were fed diets containing the test material at a dose level o f 0 (control group; fed basal diet only), 3, 30, or 300 ppm. During Week 5, five animals/sex/group were sacrificed to obtain liver samples for determination of hepatic palmitoyl CoA oxidase activity (by Covance) and analysis for PFOS and metabolites (by 3M). One female fed 3 ppm was sacrificed and necropsied during Week 9 because of poor health (unscheduled sacrifice). The remaining animals were sacrificed and necropsied during W eek 14 (terminal sacrifice). Blood was collected for hematology and clinical chemistry tests during Weeks 5 and 14. Urine was collected for urinalysis tests during W eek 14. At necropsy, macroscopic observations were recorded, organ weights were obtained (terminal sacrifice only), and tissues were placed in fixative as specified by the protocol. In addition, samples o f liver were collected at the terminal sacrifice for evaluation o f proliferation cell nuclear antigen (PCNA; by Pathology Associates International; five animals/sex/group), and both scheduled sacrifices for determination of hepatic palmitoyl CoA oxidase activity (by Covance) and analysis for PFOS and metabolites (by 3M). Microscopic examinations were done on protocol-required tissues from all control and high-dose animals sacrificed during W eek 14 and the 3 ppm dose group female sacrificed in a moribund condition during Week 9 (unscheduled sacrifice). In addition, livers, stomachs, and macroscopic 31 000034 Covance 6329-225 3M T-6314.1 lesions were examined from all terminal sacrifice animals fed 30 ppm, and macroscopic lesions and livers only were examined from animals fed 3 ppm. Statistically significant differences cited in the Results and Discussion section are based on comparisons between the control and treated groups. RESULTS AND DISCUSSION Mortality One female fed 3 ppm (Animal No. C96016) was sacrificed during Week 9 (Day 59) because of poor health. All other animals survived to the respective scheduled sacrifice. Clinical Pathology Weeks 5 and 14. There were several statistically significant or otherwise notable differences for clinical pathology results between control and treated animals. Differences considered to be effects o f the test material were lower hematocrit for males and females fed 100 ppm; higher urea nitrogen for males and females fed 100 ppm; higher albumin for males fed 100 ppm, lower globulin for males fed 30 or 100 ppm; lower cholesterol and triglycerides for males fed 30 or 100 ppm and females fed 100 ppm; higher alanine aminotransferase for males fed 100 ppm; and higher hepatic palmitoyl CoA oxidase for males and females fed 100 ppm. The effects were relatively mild with the exception o f those on cholesterol and triglycerides for the males fed 100 ppm; those effects were considered to be of moderate severity. All o f the test material-related clinical pathology findings were more prominent at Week 14 than at W eek 5. The mild effects on hematocrit and globulin were consistent with animals failing to gain weight appropriately. Although mildly higher urea nitrogen and albumin suggested a relative dehydration for animals given 100 ppm, there were no effects on urine volume or urine specific gravity consistent with dehydration. The mild effect on alanine aminotransferase was indicative o f the hepatocellular degeneration, and mildly higher hepatic palmitoyl CoA oxidase was indicative o f peroxisomal proliferation. The effects on cholesterol and triglycerides were the most prominent findings, and suggested lipid metabolism by the liver was altered. 32 000035 Covance 6329-225 3M T-6314.1 Of uncertain relationship to administration of the test material was statistically lower mean corpuscular volume for females fed 100 ppm. The difference for mean corpuscular volume became smaller over time (i.e., from Week 5 to Week 14). Other statistically significant differences were considered incidental and unrelated to administration o f the test material. Anatomic Pathology U nscheduled D eaths. The one female fed 3 ppm that was sacrificed in a moribund condition on Day 59 (Animal No. C96016) had no macroscopic or microscopic changes to indicate that its moribund condition was test material-related. Term inal Sacrifice Term inal Body W eights and O rgan W eights. Test material-related changes were seen in the terminal body weights and in absolute and relative liver weights in animals fed 30 and 100 ppm N-MeFOSE. Mean terminal body weights were statistically significantly decreased in males and females that were fed 100 ppm o f N-MeFOSE and in males only fed 30 ppm. The decreased mean body weights at both dose levels were considered to be test material-related. Statistically significant and test material-related increases were seen in the mean liver-to-body weight percentage and the mean liver-to-brain weight ratio in males fed 30 ppm, in mean absolute liver weight and mean liver-to-body weight percentage in females fed 30 ppm, and in all liver weight parameters in males and females fed 100 ppm. The liver weight increases correlated macroscopically with large livers in 3 o f 15 males in the 100 ppm dose group and microscopically with the presence of hepatocellular hypertrophy in all males and females in the high-dose group. 33 000036 Covance 6329-225 ________________________________________________________________________ 3M T-6314.1 Additional statistically significant absolute or relative organ weight changes affected several other organs in both sexes and in multiple dose groups. Because there were no macroscopic o r microscopic findings that correlated with the weight changes, the remaining organ weight variations were considered to be within the range of normal biologic variation or were attributed to the lower body weights in treated versus control animals. M acroscopic Findings. Test material-related macroscopic findings were noted at a low incidence in the liver and glandular stomach of males and females fed 100 ppm N-MeFOSE. Livers that were large were seen in 3 o f 15 males and in 0 females fed 100 ppm, and diffusely dark livers occurred in 2 o f 15 males and 1 o f 15 females fed 100 ppm. No liver changes occurred in animals fed the control material or in animals fed lower doses o f N-MeFOSE. The large and diffusely dark livers correlated microscopically with hepatocellular hypertrophy in the affected animals. In the glandular stomachs, dark foci or areas occurred at an incidence o f 0 o f 15, 1 o f 15, 0 o f 15, and 2 of 15 in males, and at an incidence of 0 o f 15, 0 of 14, 0 of 15, and 3 o f 15 in females in the control, 3 ppm, 30 ppm, and 100 ppm groups respectively. The dark foci or areas generally correlated microscopically with small erosions in the glandular mucosa. Diffuse reddening and mottling o f the thymus and mandibular lymph nodes as well as red foci or areas in the thymus were relatively common findings and frequently correlated microscopically with hemorrhage in the affected organs. Because these findings did not occur in a dose-related manner and because rats in multiple dose groups, including control males, were sometimes affected, the findings were considered to be agonal changes that were not associated with test material administration. All remaining macroscopic findings were considered to be spontaneous and incidental and not related to test material administration. M icroscopic Findings. Test material-related microscopic findings were seen in the liver o f animals fed 30 and 100 ppm o f N-MeFOSE and in the glandular stomach o f males and females in the 100 ppm group only. There were no test material-related findings in the livers o f animals fed 3 ppm 34 000037 Covance 6329-225 3M T-6314.1 Test material-related findings in the liver included hepatocellular hypertrophy, coagulative necrosis, hepatocellular pigment, and hepatocellular vacuolation. The incidence and severity of these findings tended to be greater in 100 ppm animals. The incidence of pertinent liver findings is presented in Text Table 1. Text Table 1 Incidence of Selected Microscopic Findings in the Liver Group Number/Sex Number Examined 1M 2M 3M 4M 15 15 15 15 IF 2F 3F 4F 15 14 15 15 Hypertrophy, hepatocellular, diffuse 0 0 0 0 Hypertrophy, hepatocellular, Centrilobular 0 0 14 15 Necrosis, coagulative 0003 Pigment, hepatocellular 0002 Vacuolation, hepatocellular, centrilobular to midzonal 00 27 Vacuolation, hepatocellular, diffuse 0022 0001 0 0 7 14 00 10 0007 0002 0000 As noted in the above table, hepatocellular hypertrophy generally affected centrilobular areas of the liver in animals fed 30 and 100 ppm, but the liver was more diffusely hypertrophied in one female fed 100 ppm The hypertrophic hepatocytes were enlarged with abundant cytoplasm that often had a granular to globular eosinophilic appearance. In some animals in the high-dose group (two males and seven females), the cytoplasm of hepatocytes also contained minimal amounts o f a brown granular pigment at the periphery o f the cell. In addition, liver cells frequently were vacuolated (see Text Table 1), particularly in males given 100 p p m with the vacuolation generally affecting hepatocytes in centrilobular and midzonal areas. Diffuse hepatocellular vacuolation was also seen in two males in each of the 30 and 100 ppm dose groups, but in no other animals. Lastly, minimal to slight coagulative necrosis seen in 3 o f 15 males fed 100 ppm and 1 o f 15 females fed 30 ppm was likely related to dietary administration o f the test material since no control or 3 ppm dose group animals were similarly affected. A possible test material-related change in the glandular stomach was the presence of mucosal erosions. The erosions were o f minimal to slight severity and involved a very small portion o f the mucosal surface in all cases. The erosions were seen with an 35 000038 Covance 6329-225 3M T-6314.1 incidence o f 0 o f 15, 0 o f 15, and 2 o f 15 in males, and at an incidence o f 0 o f 15, 0 o f 15, and 3 o f 15 in females in the control, 30 ppm, and 100 ppm groups respectively. The presence o f erosions microscopically generally correlated with the dark foci or areas seen in the gastric mucosa at necropsy. One male fed 3 ppm also had a slight gastric erosion that was collected as a gross lesion at necropsy. Since no erosions were seen in any o f the animals' stomachs examined from animals fed 30 ppm, the lesion in the 3 ppm male was considered unlikely to be test material-related. All remaining microscopic findings were considered to be spontaneous and incidental changes and typical o f rats o f this age and strain. Robert L.

Because different models round off or truncate numbers differently, values in some tables (e.g., means, standard deviations, or individual values) may differ slightly from those in other tables, from individually calculated data, or from statistical analysis data. Neither the integrity nor the interpretation o f the data was affected by these differences. The number o f animals listed in the heading o f the summary tables for clinical observations reflects the number o f animals assigned to each group at the start o f the study. The summary table for clinical observations indicate the number o f animals for which a condition was observed without regard to the specific nature, severity, reversibility, number o f incidences/animal, or the length of time the condition persisted. Only observations other than normal are indicated on the summary clinical observations tables. Each animal with observations recorded as "Normal" throughout the study has the comment "Animal has no significant findings" indicated on the individual clinical observations tables. The specific details for comments in the individual clinical observations tables that are indicated with a "C" can be found at the end of each group for each sex. The day o f initiation of treatment is "Day 1, W eek 1." Body weight data are entered at the start o f a study week (e.g., a body weight recorded on Day 1 is considered a Week 1 body weight, a body weight recorded on Day 8 is considered a Week 2 body weight). Body weight change data are calculated from the first day of the study week to the first day of the following study week (e.g., Week 1 values are calculated from Day 1 through 7) and are indicated in the tables with the day being the first day o f the following week (e.g., Week 1 values are indicated as "Day 8."). Weekly food consumption and test material consumption are calculated from the first day o f the study week to the first day of the following study week (e.g., Week 1 values are calculated from Day 1 through 7). The values for summary and individual test material consumption are reported with more significant figures than is appropriate for the data due to limitations o f the data collection and reporting software. 37 000040 COMMENTS ON THE DATA (Continued) Covance 6329-225 3M T-6314.1 Food consumption values are reported in whole numbers; however, PTS carries food consumption values to one place to the right o f the decimal for food efficiency and test material consumption calculations. The differences in values generated do not influence the interpretation of the calculation. The comment "SPILLED" on individual food consumption data tables indicates that food consumption was not recorded due to spillage during the interval. The comment "NOT TAKEN" on individual food consumption data tables indicates the animal died before the end o f the food consumption interval. Differences in the population size (N) on the summary tables for clinical and anatomic pathology are explained on the individual data tables or the codes sheets. The calculation for individual test material consumption is: Test material consumption = ________________________ Diet ConcentrationxFood Consumption________________________ Food Consumption Intervalx[First Body Weight of Interval* (Daily Body Weight GainxDay Factor)] where: Daily Body Weight Gain = ______ Last Body Weight of Interval- First Body Weight of Interval______ Day of Last Body Weight of Interval- Day of First Body Weight of Interval and: Day Factor = (Food Consumption Start Day- Day of First Body Weight of Interval) + ^ 0(xl Consumption Interval and: Food Consumption Interval = Food Consumption End Day- Food Consumption Start Day 38 000041 CODES, ABBREVIATIONS, AND UNITS Covance 6329-225 3M T-6314.1 General Codes and Abbreviations Codes for Clinical Pathology Abbreviations and Units for Clinical Hematology Abbreviations and Units for Clinical Chemistry Abbreviations and Units for Clinical Urinalysis Codes for Anatomic Pathology Note: The following lists o f codes, abbreviations, and units are used by Covance.

Specified nutrient and contaminant analyses are on file at Covance-Madison. 131 000104 Covance 6329-225 __________Page 6 Water Ad libitum. Samples o f the water are routinely analyzed for specified microorganisms and environmental contaminants. The results are on file at Covance-Madison. Contaminants There are no known contaminants in the diet or water at levels that might interfere with this study. Environment Environmental controls for the animal room will be set to maintain 18 to 26 C, a relative humidity o f 30 to 70%, and a 12-hour light/12-hour dark cycle. The light/dark cycle may be interrupted to accommodate in-life procedures. Acclimation At least 1 week Randomization Selection o f animals for the study will be based on clinical observations, ophthalmic examinations, and other data as appropriate. Animals will be assigned to treatment groups using a computerized blocking procedure designed to achieve body weight balance with respect to treatment groups. At the time o f randomization, the weight variation o f the animals of each sex used will not exceed 2 standard deviations o f the mean weight, and the mean body weight for each group o f each sex will not be statistically different at the 5.0% probability level. Justification Rats historically have been used in safety evaluation studies and are recommended by appropriate regulatory agencies. 132 000135 Group Designations and Dietary Levels Covane* 6329-225 __________Page 7 Number o f Animals Dietary Levels Group Male Female (ppm MeFOS)3 1 (Control)15 20 20 0 2 (Low) 20 20 3 3 (Mid) 20 20 30 4 (High) 20 20 100 a Dose levels are expressed as ppm o f MeFOS. b The control animals will receive the basal diet only. Dosing Procedures Method of Administration Dietary, 7 days/week for at least 13 weeks. Treatment will continue through the day before necropsy. Reason for Dosing Route The potential route o f exposure in humans is oral. Dose Preparation All dose preparations will be mixed according to the study-specific mixing procedure developed by Covance. Dose concentrations will be based on the MeFOS content as supplied. All dose preparations will be stored at room temperature. Before initiation o f treatment, dose preparations of 1 ppm, 3 ppm, 30 ppm, 100 ppm and 500 ppm will be mixed. Dose preparations will be mixed at least once every 4 weeks during the in-life phase. Retention Samples During the in-life phase, samples (approximately 100 g) will be taken from each dose preparation sampled for dose analyses and stored at room temperature. Unless used for analyses, these samples will be discarded approximately 1 month after completion o f the in-life phase. 133 000136 Covance 6329-225 _________ Page 8 Dose Analyses By Covance, using a method supplied by the Sponsor and validated by Covance Homogeneity Homogeneity will be determined for 3-ppm, 30-ppm, and 100-ppm dose preparations once pretest. One sample (approximately 100 g) each from the top, middle, and bottom o f the dose preparations mixed for homogeneity analyses will be collected, divided into three subsamples for extraction and analysis, and analyzed for test material content. All samples will be stored at room temperature until analyzed within 7 days after mixing. Homogeneity analysis will be repeated if batch size changes by more than 30%. Stability Four samples (approximately 100 g each) will be taken from the 1-ppm dose level concentration o f diet preparations mixed pretest. One sample will be analyzed on the day o f mixing and used as the baseline value. One sample will be stored at room temperature for at least 19 days, then analyzed. A third sample will be stored at room temperature after at least 32 days, then analyzed. The remaining sample will be stored in a freezer set to maintain -10 to -30C for 8 weeks, then analyzed. In addition, tw o samples (approximately 100 g each) will be taken from the 500-ppm dose preparation mixed pretest. One sample will be analyzed on the day o f mixing. The second sample will be will be stored at room temperature after at least 32 days, then analyzed. Dose Confirm ation During the in-life phase, samples (approximately 100 g) from all dose preparations will be analyzed. All samples will be stored at room temperature until analyzed. 134 000137 Observation of Animals Covance 6329-225 __________ Page 9 Clinical Observations Each animal will be observed twice daily (a.m. and p.m.) for mortality and moribundity, recording findings as they are observed.

Liver PFOS Analysis At scheduled sacrifices, the remaining portion of the liver from each animal after other required collections will be stored in a freezer set to maintain -60 to -80 C. Samples will be packed on dry ice and shipped to Kris J. Hansen, PhD, 3M Environmental Technology and Safety Services. Liver samples will be analyzed for PFOS and metabolites by the Sponsor. Results will be reported separately by the Sponsor. Tissue Preservation The following tissues (when present) from each animal that is found dead, sacrificed at an unscheduled interval, or sacrificed at the scheduled sacrifice after 13 weeks o f treatment will be preserved inl0% neutral-buffered formalin: 139 000142 Covance 6329-225 _________Page 14 adrenal (2) aorta brain cecum cervix colon duodenum epididymis (2) esophagus eye (2) femur with bone marrow (articular surface o f the of the distal end) Harderian gland heart ileum with Peyer's patch (lymphoid aggregate) jejunum kidney (2) lesions liver lung with mainstem bronchi lymph nodes (mesenteric and mandibular) mammary glands (females only) ovary (2) pancreas pituitary prostate rectum salivary gland [mandibular (2)] sciatic nerve seminal vesicle (2) skeletal muscle (thigh) skin spinal cord (cervical, mid-thoracic, and lumbar) spleen sternum with bone marrow stomach testis (2) thymus thyroid (2) with parathyroid trachea urinary bladder uterus vagina Zymbal's gland Histopathology Tissues (as appropriate) from each animal in the control and high-dose groups and each animal that dies or is sacrificed at an unscheduled interval will be embedded in paraffin, sectioned, stained with hematoxylin and eosin, and examined microscopically. Macroscopic lesions from animals in the low- and mid-dose groups will be embedded in paraffin, sectioned, stained with hematoxylin and eosin, and examined microscopically. Suspected target organs noted at the high dose will be examined microscopically from each animal (at the Sponsor's request and added by amendment). Reports One copy o f the draft report will be sent to the Sponsor. The report will include the following information: 140 000143 Experimental Design and Methods Covance 6329-225 _________Page 15 Results dose analyses mortality clinical observations body weights body weight changes food consumption test material consumption ophthalmic findings clinical pathology results palmitoyl CoA oxidase activities macroscopic observations microscopic observations cell proliferation assessments (provided by the Sponsor's designee) Statistical Evaluation Levene's test will be done to test for variance homogeneity. In the case o f heterogeneity of variance at p s 0.05, transformations will be used to stabilize the variance. Comparison tests will take variance heterogeneity into consideration. One-way analysis o f variance (ANOVA) will be used (if applicable) to analyze body weights, body weight changes, food consumption, continuous clinical pathology values, and organ weight data. If the ANOVA is significant, Dunnett's t-test will be used for control versus treated group comparisons. If the ANOVA shows significance for body weights at W eek 1, one-way analysis o f covariance (ANCOVA) will be used to analyze body weights, with initial body weights as the covariate. If the ANCOVA is significant, covariate-adjusted means will be used for control versus treated group comparisons. Group comparisons (Groups 2 through 4 versus Group 1) will be evaluated at the 5.0%, two-tailed probability level. Only data collected on or after the first day o f treatment will be analyzed statistically. 141 000144 Covance 6329-225 _________Page 16 At the end o f 1 year after issuance o f the audited draft report, if no requested revisions or instructions to finalize have been communicated by the Sponsor, then the audited draft report will be considered 'final' and issued as the final report, signed by the study director, and submitted to the Sponsor. Any modifications or changes to the audited draft report requested 1 year after issuance will be performed at additional cost to the Sponsor. Two copies o f the signed final report (one unbound and one bound) will be sent to the client. Record Retention All raw data, documentation, records, protocol, specimens, and final report generated as a result o f this study will be archived in the storage facilities o f Covance-Madison for a period o f 1 year following submission o f the final report to the Sponsor. One year after submission o f the final report, the aforementioned materials will be sent to the Sponsor, and a return fee will be charged; all raw data stored on magnetic media, protocol, study correspondence, and the original final report will be retained by Covance. The Sponsor may elect to have the materials retained in the Covance archives for an additional period o f time, and Covance will charge a storage fee. If the Sponsor chooses to have Covance dispose o f the materials, a disposal fee will be charged. PCNA antigen evaluation data will be retained by Pathology Associates International. Liver and serum samples sent to the Sponsor and analysis data will be retained by the Sponsor. 142 0 0 0 1 ^ 5 PROTOCOL APPROVAL Covance 6329-225 _________ Page 17 Andrew M.

This report, submitted by Pathology Associates International (PAI) to the study Sponsor, 3M, represents the cell proliferation findings and interpretation for Covance Study N um ber 6329-225 entitled " 13-Week Dietary Toxicity Study with N-Methyl Perfluorooctanesulfonamido Ethanol (N-MeFOSE, T-6314) In R ats" . All aspects o f the tasks associated with PA I's p o rtio n o f this study were conducted in compliance with the Food and Drug Administration Good Laboratory Practice (GLP) Regulations as set forth in Title 21 o f the US Code o f Federal R egulations, Part 58, issued December 22,1978 (effective June 20,1979), and with any applicable am endm ents. MATERIALS AND METHODS Tissue Collection for Cell Proliferation Five animals per sex per group in groups 1 through 4 were sacrificed during w eek 13 for hepatocellular proliferation. A section of the left lateral lobe o f the liver from each o f 5 rats per group (groups 1-4) was fixed and processed to paraffin block by Covance per protocol specifications. Tissue blocks were shipped to PAI for sectioning and staining. From each block, a slide was prepared for H&E evaluation and immunohistochemical detection o f proliferating cell nuclear antigen (PCNA), a marker o f cell proliferation. Immunohistocheimstry for Cell Proliferation Sections o f paraffin-embedded tissues were cut at 5 pm and placed on positively charged slides (Superfrost Plus, Fisher Scientific, Pittsburgh, PA) to ensure adhesion during processing for PCNA. Standard immunohistochemical methods w ere used to stain tissues for PCNA (PAI's SOP for immunohistochemistry). Briefly, tissue sections were incubated with a monoclonal antibody to PCNA (DAKO, lot #016, PAI No. A 1723) and reagents required for the avidin-biotin peroxidase (ABC Kit, lot #PK-6100, PAI No. K 324) method for the detection o f the antigenantibody complex. PCNA expression in cells in all phases o f the cell cycle (G,, S, G2 and M) was localized by the chromagen 3,3'-diaminobenzidine (DAB; Sigma Chemical Co., lot #18H8201). Tissue sections were counterstained w ith hematoxylin. A negative control slide was included in the staining run and consisted o f study tissue that was not incubated with the primary antibody. 549 0005' Wt Covance 6329-225 3M T-6314.1 Final Cell Proliferation Report Covance Study Number 6329-225 Page 4 Cell Proliferation Measurements For cell proliferation evaluations, slides were first perused at low magnification (100X) to judge quality o f staining, processing and sectioning, pattern of cell labeling (e.g., centrilobular or panlobular, extrahepatocellular proliferation, such as Kupffer cells, bile duct epithelium, endothelium), and histomorphologic changes. Cell proliferation was then quantified at higher magnification (200X). The percentage o f hepatocytes in S phase o f the cell cycle (labeling index, LI) was determined by scoring at least 3000 hepatocytes in 10 randomly selected fields per animal. Histomorphology was further assessed by evaluating the serial H&E slide for each animal evaluated for cell proliferation. Statistical Analysis The Student's Mest (two-sided, unequal variance) was used to test for statistical significance in LI between control and treatment groups using Microsoft Excel version 5.0. A P value o f less than 0.05 was judged to be statistically significant. RESULTS Cell Proliferation Individual animal and group mean cell proliferation data are presented in Section II (Table 1). The percentage o f proliferating hepatocytes, as determined by the labeling index (LI), was not significantly increased in treated groups compared to that o f controls in either male or female rats. The LI was significantly less than controls in female rats from groups 3 and 4. Histopathology Sections from the same tissue blocks used for preparation of PCNA-stained slides were stained with hematoxylin and eosin (H&E) for histopathologic evaluation to facilitate the interpretation o f the immunostained slides. Individual animal findings and group summaries are presented in Appendix I. The results showed no changes in the liver tissue o f male and female rats that would alter the interpretation o f the PCNA staining in this study. 550 0 0 0 5 5 3 SUMMARY Covance 6329-225 3M T-6314.1 Final Cell Proliferation Report Covance Study Number 6329-225 Page 5 In the present study, cell proliferation was measured within the liver o f male and female rats from control (0 ppm ), low dose (3 ppm), mid dose (30 ppm) and high dose (100 ppm ) after 13 weeks on study. No statistically significant increases in cell proliferation, as determined by the PCNA labeling index (LI) were observed in male or female rats after 13 w eeks o f N -m ethyl perfluorooctanesulfonamido ethanol. Although cell proliferation was statistically less than controls in mid dose (30 ppm) and high dose (100 ppm) females, the decrease was not doserelated, and the individual animal values were within the range observed in control animals. Therefore, this decrease was not considered to be biologically relevant. 551 0 0 0 5 5 4 Covance 6329-225 3M T-6314.1 Final Cell Proliferation Report Covance Study Number 6329-225 Page 6 II.
