Purity and Stability The Sponsor assumes responsibility for purity and stability determinations (including under test conditions). Storage and Retention The test material was stored at room temperature. Any unused test material will be returned to the Sponsor after issuance of the final report according to Hazleton Wisconsin (HWI) Standard Operating Procedure (SOP). Safety Precautions The test material handling procedures were according to HWI SOPs and policies. TEST SYSTEM Test Animal Adult albino rats of the Crl:CD(SD)BR strain were procured from Charles River Laboratories, Inc. and maintained at the Hazleton Wisconsin facility at 3802 Packers Avenue, Madison, Wisconsin. Animal husbandry and housing at HWI comply with standards outlined in the "Guide for the Care and Use of Laboratory Animals".2 The animals were separated by sex, housed in temperature- and humidity-controlled quarters, provided continuous access to Laboratory Rodent Diet #5001, PMI Feeds, Inc., and water, and held for an acclimation period of at least 7 days. The feed is routinely analyzed by the manufacturer for nutritional components and environmental contaminants. Samples of the water are periodically analyzed by HWI. There were no known contaminants in the feed or water that would have interfered with or affected the results of the study. 005744 HWI Number: 40200468 Sample: T-5898 Page 4 Ten male and 10 female acclimated rats, weighing from 225 to 280 g, were assigned to two treatment groups of 500 and 5,000 mg/kg of body weight. Each dose level consisted of five male and five female rats. Animals were group housed by sex and identified by animal number and corresponding ear tag throughout the study. Food and water were available ad libitum, except for an overnight period before test material administration when food, but not water, was withheld. If variations from the required temperature and humidity conditions existed, they were documented and considered to have had no adverse effect on the study outcome. Justification for Species Selection Historically, rats have been used as a representative of a rodent species and are preferred by various regulatory agencies. PROCEDURES Preparation and Administration of Test Material The undiluted test material was administered by gavage using a bulk density determination of 1.13 g/mL to determine the dose volume for each dose level. An individual dose was calculated for each animal based on its fasted body weight. Reason for Route of Administration Historically, the oral route has been the route of choice for administering a known amount of test material. Observations Clinical observations and mortality checks were conducted at approximately 1, 2.5, and 4 hours after test material administration. Additional clinical observations and twice a day mortality checks (morning and afternoon) were conducted daily thereafter for 14 days. Body weights were determined before test material administration (Day 0). Additional body weights were determined at Day 7, at termination of the experimental phase (Day 14), or at death when survival exceeded 1 day. 005745 HWI Number: 40200468 Sample: T-5898 Page 5 Patholoq v At termination of the experimental phase, surviving animals were euthanized. All animals, whether found dead during the study or euthanized, were subjected to an abbreviated gross necropsy examination and any abnormalities were recorded. After necropsy, the animals were discarded and no tissues were saved. Statistical Analyses No statistical analyses were required by the protocol. Location of Raw Data. Records, and Final Report The raw data, records, and a copy of the final report will be retained in the archives of HWI in accordance with HWI SOP. 005746 HWI Number: 40200468 Sample: T-5898 Page 6 SUMMARY OF RESULTS Test Animal: Albino Rats - Crl:CD(SD)BR Source: Charles River Laboratories, Inc., Portage, MI Date Animals Received: 01/14, 01/28, 2/04, and 02/25/94 Experimental Start Date: 02/22/94 Experimental Termination Date: 03/23/94 Estimated Oral LDS0 : Male - Between 500 and 5,000 mg/kg of Body Weight Female - Between 500 and 5,000 mg/kg of Body Weight Animal Number C29181 C29232 C29184 C29234 C29190 Mean C27615 C28047 C28043 C28070 C28050 Mean Individual Body Weights (g) Day 0 Weiaht Day 7_____ Weiaht Gain* Dav 14 Weiaht Gain* Males (500 ma/kal 267 224 -43 319 52 274 302 28 382 108 253 284 31 354 101 280 312 32 390 110 257 289 32 353 96 266 282 16 360 93 Females J 500,mg/kg) 241 228 -13 261 20 230 225 -5 255 25 225 180 -45 (131)8 - 232 207 -25 239 7 238 225 -13 250 12 233 213 -20 251 13 * Gain from the Day 0 body weight.

HWI Number: 40200468 Sample: T-5898 Page 13 DISCUSSION The acute oral toxicity of T-5898 was evaluated in male and female rats when administered as a single gavage dose at levels of 500 and 5,000 mg/kg of body weight. Based on the observed mortality, the estimated oral LDS0 for male and female rats was determined to be between 500 and 5,000 mg/kg. Clinical signs of toxicity included thin appearance, hunched posture, hypoactivity, aggressive behavior, staggered gait, red-stained face, clear or red nasal discharge, miosis, lacrimation, dark staining around eyes, dyspnea, soft stool, yellow- or dark-stained urogenital area, alopecia (rear quarters), and death. All mortality occurred within 8 days of test material administration. Six of the 10 animals treated at 500 mg/kg exhibited body weight losses of 5 to 45 g during the first week of the study.

NIH Publication No. 86-23 (revised 1985). 005754 HWI Number: 40200468 Sample: T-5898 Page 14 PATHOLOGY REPORT There were 10 rats (five males and five females) each from dose levels of 500 and 5,000 mg/kg, necropsied. All animals given 5,000 mg/kg and one female from the group given 500 mg/kg died on test (DOT). The remaining surviving animals were euthanized and necropsied at the termination of the study. The dose level, day of death, and gross observations recorded for each animal are in the Individual Pathology Comments that precede this report. At necropsy, most of the changes observed were in the animals that died on test. Brown stains in the perianal region and red nasal discharge were indicative of acute death. All other changes in these animals were attributed to post mortem autolysis. The alopecia and fluid filled uterine horns observed in two of the females surviving to study termination were considered incidental findings and unrelated to the test material. There were no visible lesions in any of the remaining animals in either group.
