BOX 7545 MADISON, Wl 53707 USA HLA Number: 91201741 Sample: T-4416 Page 3 METHODOLOGY Objective: To assess the relative level of ocular irritation/corrosion produced following a single exposure of a test substance to one eye of albino rabbits according to the Organisation for Economic Cooperation and Development's Guidelines for Testing Chemicals.1 Test Material: T-4416 Physical Description: Purity and Stability: Storage and Retention: Safety Precautions: Clear colorless liquid Sponsor assumes responsibility for purity and stability determinations (including under test conditions). The test material was stored at room temperature. Any unused material will be returned to Sponsor according to HLA Standard Operating Procedure. Normal handling procedures were used according to HLA Standard Operating Procedure. Test Animal: Adult albino rabbits, Hra:(NZW)SPF, were procured, maintained individually in screen-bottom cages in temperature- and humidity-controlled quarters, provided access to water ad libitum and a measured amount of High Fiber Rabbit Chow 5326, Purina Mills, Inc., and held for an acclimation period of at least 7 days. Animal husbandry and housing at HLA comply with standards outlined in the "Guide for the Care and Use of Laboratory Animals".2 If variations from the prescribed environmental conditions existed, they were documented and considered to have no effect on the study outcome. No contaminants were expected to have been present in the feed or water which would have interfered with or affected the results of the study. One male and two female acclimated animals, weighing from 2148 to 2500 g, were chosen at random for the test. The animals' eyes were examined within 24 hours prior to test material administration using sodium fluorescein dye procedures. Only those animals with no sign of ocular injury or irritation were used. Test animals were identified by animal number and corresponding ear tag. Reason for Species Selection: Historically, the New Zealand White albino rabbit is the animal of choice based upon its large orbit and nonpigmented iris. Preparation and Administration of Test Material: The sample was dosed as received. The pH was determined to be 9.9.

BOX 7545 MADISON, Wl 53707 USA HLA Number: 91201741 Sample: T-4416 Page 4 Treatment: Each rabbit received 0.1 mL of the test material placed into the everted lower lid of one eye, with the contralateral eye serving as the untreated control. The upper and lower lids were gently held together for 1 second to prevent loss of material and then released. The eyes of the rabbits remained unflushed. Reason for Route of Administration: Historically, the ocular route is the route of choice based on the method of Draize. Observations: The treated eyes were observed for ocular irritation at 1, 24, 48, 72 and 96 hours, and Days 7, 14 and 21 after treatment. At the 24- and 72-hour, and 7-, 14- and 21-day readings, sodium fluorescein was used to aid in revealing possible corneal injury. Irritation was graded and scored according to the Draize technique. Animals were weighed just prior to test material administration and at weekly intervals throughout the study. Termination: At termination of the experimental phase, all animals were euthanatized and discarded. Statistical Methods: No statistical method was performed. Location of Raw Data and Final Report: The raw data and a copy of the final report will be retained in the archives of HLA.
