The rabbits were individually housed in stainless steel cages. Animal identification consisted of uniquely numbered ear markings and cage cards. On Study Day 1, the animals were approximately 16 weeks old. Group Number Group Designation Dosage Level (mg) Number of Animals Females 1 Limit Dose 1oo* 3 I J *Due to test material adherence to the weigh boats, approximately 80 mg of test material was instilled into each animal's left eye. The test material (approximately 80 mg) was instilled into the left eye of each animal on Study Day 1. Both eyes were held closed for approximately two seconds. Both eyes were flushed with approximately 5 mL of 0.9% saline after the 24-hour score was recorded. Observations for mortality and moribundity were recorded twice daily (a.m. and p.m.). Clinical observations were recorded predose, approximately one hour postdose, once daily thereafter, and when a change was noted. Predose clinical observations were all normal while at one hour postdose, excessive lacrimation of the left eye was recorded in all three rabbits. The excessive lacrimation of the left eye persisted throughout the remainder of the study. All animals' eyes were normal when the pretest ophthalmologic examinations were performed. Maximum average ocular scores for 24- and 72-hours postdose were 30 and 35, respectively. By definition, the findings at 24- and 72-hours will not maintain the categories of non-irritating, practically non-irritating, or minimally irritating. Ocular irritation scores at the 7-day reading were less than 10 (scoreswere 6, 4, and 30 for the three rabbits) for 67% of the rabbits. Also, the seven-day mean score was 13. By definition, the resulting scores indicate that T-7485 should be rated as a moderate irritant. In conclusion, instillation of approximately 80 mg of T-7485 produced a moderate irritant rating. Page 6 Acute Ocular Irritation Study in New Zealand White Rabbits Study Number: 132-005 OBJECTIVE The objective of this study was to determine the acute effects of a single ocular application of test material to New Zealand White rabbits. MATERIALS AND METHODS TEST AND CONTROL MATERIALS: The test material and vehicle were identified as follows: Test Material: Lot Number: Date Received: Physical Description: Storage: Amount Received: T-7485 (Potassium PerfluorobutaneSulfonate, PFBS) 2 April 6, 2000 White Powder Room Temperature 500 grams The Sponsor assumed responsibility for characterization (identity, purity, and stability) determinations of the test material. The test material was inventoriedwhen received at Primedica Redfield, and a record of all test material usage was maintained. The Certificate of Analysis for the test material is in Appendix 3. The test material was used as received. TEST ANIMALS: Healthy female New Zealand White rabbits were received from Myrtle's Rabbitry, Inc. for use on the study. The animals were individually housed in stainless steel cages. Animal identification consisted of uniquely numbered ear markings and cage cards. On Study Day 1, the animals were approximately 16 weeks old. Teklad Certified Rabbit Diet #8630 was provided at approximately 125 grams per day, and filtered tap water was provided ad libitum. The feed and water were routinely analyzed for contaminants. There were no known contaminants in the feed or water that would be expected to affect the results of the study. The results of these analyses are on file at Primedica Redfield. Group Number 1 Group Designation Limit Dose Dosage Level (mg) 1oo* Number of Animals Females 3 The test material (approximately 80 mg) was instilled into the left eye of each animal on Study Day 1. Both eyes were held closed for approximately two seconds. Both eyes were flushed with approximately 5 mL of 0.9% saline after the 24-hour score was recorded. Page 7 Acute Ocular Irritation Study in New Zealand White Rabbits Study Number: 132-005 JUSTIFICATION FOR SPECIES SELECTION, NUMBER OF ANIMALS, ROUTE OF ADMINISTRATION, AND DOSE LEVEL: Rabbits are an animal model for acute toxicity studies of this type. The number of animals assigned to the study represented the minimum required to meet the objective of the study and the OECD guidelines (M05). In the assessment and evaluation of the toxic characteristics of a substance, determination of the irritant andlor corrosive effects on the eyes is necessary. Dose levels were chosen by the OECD guideline M05. CLINICAL OBSERVATIONS: Observations for mortality and moribundity were recorded twice daily (a.m. and p.m.). Clinical observations were recorded predose, approximately one hour postdose, once daily thereafter, and when a change was noted. OPHTHALMOLOGIC EXAMINATIONS: An ophthalmological examination was performed by the Staff Veterinarian prior to dose administration to verify that all animals' eyes were normal. OCULAR SCORING: Ocular irritation was scored at approximately 1, 24, 48, and 72 hours postdose and daily on Study Days 5 through 21 using the scoring scale found in the protocol (Appendix 4). . STUDY TERMINATION: On Study Day 21, the study was terminated and all animals were euthanized via an overdose of sodium pentobarbital. No necropsies were performed. STATISTICS: No statistical analyses were performed. ARCHIVAL STATEMENT All original data and the original final report will be retained at Primedica Redfield's archives, located at 100 East Boone Street, Redfield, Arkansas, for a period of five years after issuance of the final report. After this time, the Sponsor will be contacted for disposition instructions. Page 8 Acute Ocular Irritation Study in New Zealand White Rabbits Study Number: 132-005 RESULTS CLINICAL OBSERVATIONS: Observations for mortality and moribundity were recorded twice daily (am. and p.m.). Clinical observations were recorded predose, approximately one hour postdose, once daily thereafter, and when a change was noted. The individual clinical observations are in Appendix 1. Predose clinical observations were all normal, while at one hour postdose, excessive lacrimation of the left eye was recorded in all three rabbits. The excessive lacrimation of the left eye persisted throughout the remainder of the study. OPHTHALMOLOGIC EXAMINATIONS All animals' eyes were normal when the pretest ophthalmologic examinations were performed. OCULAR SCORING: Due to test material adherence to sample containers, only approximately 80% of the 100 mg of test material was instilled in the left eye of the rabbits. Ocular irritation was scored at approximately 1, 24, 48, and 72 hours postdose and daily on Study Days 5 through 21 using the scoring scale found in the protocol (Appendix 4). The individual ocular scores are located in Appendix 2. Maximum average ocular scores for 24- and 72-hours postdose were 30 and 35, respectively. By definition, the findings at 24- and 72-hours will not maintain the categories of non-irritating, practically non-irritating, or minimally irritating. Ocular irritation scores at the 7-day reading were less than 10 (scores were 6,4, and 30 for the three rabbits) for 67% of the rabbits. Also, the seven-day mean score was 13. By definition, the resulting scores indicate that T-7485 should be rated as a moderate irritant (as defined in Ocular Irritation Ratings, Appendix 2). CONCLUSION In conclusion, instillation of approximately 80 mg of T-7485 produced a moderate irritant rating.

Results of these analyses are on file at Primedica Redfield. CONTAMINANTS There are no known contaminants in the feed or water that would be expected to interfere with this study. ENVIRONMENT Environmental controls are set to maintain a temperature of 16' to 22% (61' to 72F) with a relative humidity of 30% to 70%. These parameters are recorded at least once daily. A 12:12 hour lightdark cycle is maintained. Page 3 of 10 06/08/00 Page 25 Acute Ocular Irritation Study in New Zealand White Rabbits Study Number: 132-005 Primedica Redfield Protocol Protocol Number: 132005 Animals will be acclimated for a minimum of seven days prior to the study start. An adequate number of extra animalswill be purchasedso that no animal in obviously poor health is placed on test. At the request of the Study Director, excess animals may be used as replacement animals. Animals will be examined by the Staff Veterinarian prior to release of that shipment of animals for use on the study. JUSTIFICATION FOR SPECIES SELECTIONAND NUMBEROF ANIMALS Rabbits are an animal model for acute toxicity studies of this type. The number of animals assigned to this study represents the minimum required to meet the objedive(s) of the study and the OECD guidelines (M05). 5. EXPERIMENTAL METHODOLOGY STUDYDESIGN Group Number Group Designation Dosage Level (m9) Number of Animals Females FREQUENCYAND DURATION OF ADMINISTRATION One hundred milligrams of test material will be instilled into the left eye of each animal on Study Day 1. Both eyes will be held shut for approximately two seconds. Both eyes will be flushed with 0.9% saline after the 24 hour score has been recorded (SOP252.07). JUSTIFICATION FOR ROUE OF ADMINISTRATION AND DOSELEVEL In the assessment and evaluation of the toxic characteristics of a substance, determination of the irritant andor corrosive effects on the eyes of mammals. Dose levels were chosen by the OECD guideline #405. ANTEMORTEMOBSERVATIONS CLINICAL OBSERVATIONS Observations will be performed and recorded twice daily (a.m. and p.m.) for moribundity and mortality. Clinical observations will be performed, according to Primedica Redfields SOPS, and recorded predose. approximately o n e hour postdose. once daily thereafter, and when a change is noted. oPKTHALMOLCGlC .&4MlNATlONS An ophthalmological examination will be conducted by a staff veterinarian within 24 hours before testing to verify that the eyes are normal. - ~~ Page 4 of 10 06/08/00 Page 26 Acute Ocular Irritation Study in New Zealand White Rabbits Study Number: 132-005 Primedica Redfield Protocol Prorocol Number: 132-005 OCULAR SCORING Ocular irritation will be scored at approximately 1,24,48. and 72 hours postdose, as defined in AttachmentA. Ifthere is no evidence of irritation at 72 hours postdose, the study may be terminated. Extended observationmay be necessary if there is persistent corneal involvement or other Ocular irritation in order to determine the progress of the lesions and their reversibility or irreversibility. POSTMORTEM OBSERVATlONS MORISUND ANIMALSAND ANIMLSFOUNDDEAD Animals unlikely to survive until the next scheduled observation will be weighed, euthanized, and necropsied. Animals found dead will be weighed and necropsied. In either case, a complete necropsy will be performed as detailed below. Euthanasia of moribund animals will be authorized by the Study Director or Staff Veterinarian with the concurrence of the Study Director. All animals surviving to the end of the study may be returned to the testing facility's methodology population. NECROPSY All animals that die during the study will be subjected to a complete necropsy examination. A complete necropsy is defined as examination of the external surface of the body, all orifices, and the cranial, thoracic, and abdominal cavities, and their contents. Gross lesions will be preserved in a suitable fixative for possible histopathology; all other tissues will be discarded. Histopathology will be provided at additional expense to the Sponsor. 6. STAllSnCAL ANALYSS Statistical analysis will not be required. 7. REPORT An audited draft report will be sent to the Sponsor. Revisions to the initial draft report will be provided to the Sponsor by mail or fax transmission as printed copies of the corrected pages only. Additional revisions or complete copies of the revised draft reports will be provided at additional expense to the Sponsor. Three copies (one bound, two unbound) of the approved final report will be submitted to the Sponsor approximately two weeks after approval of the draft report. The final report will include all elements requiredhecommended by the regulations and guidelines.

MAINTENANCE OF RAW DATA AND RECORDS Original data or copies thereof, will be available at Primedica Redfield to facilitate auditing the study during its progress and before acceptanceof the final report When the final report is completed. all original paper data and the original final report will be retained in the archives of the laboratory for at least five years. Wet tissues, slides, and blocks (if generated) will be retained at Primedica Redfield for one year. After one year the storage of the wet tissues, slides, and blocks will be negotiated with the Sponsor. After five years the storage of the paper data will be negotiatedwith the Sponsor. The Sponsor will be notified prior to disposal of any original study data. 9. QIJAUTYASSUR~NCRE VIEW This is to certify that this protocol has been reviewed by Quality Assurance.
