No more than slightly toxic based on toxicity studies. No significant adverse health effects are expected to develop if only small amounts (less than a mouthful) are swallowed. Refer to Section 11 for toxicological information. 4. FIRST AID MEASURES If in eyes: Immediately flush with plenty of water. If easy to do, remove any contact lenses. Remove material from skin and clothing. Get medical attention. NOTE: For additional human emergency first aid or treatment guidance, call collect, anytime, day or night, FIRE FIGHTING MEASURES Flash Point: >200 degrees F (>93.3 degrees C) Hazardous Products of Combustion: None known Extinguishing Media: In case of fire, use water spray (fog), foam, dry chemical, or CO2. Unusual Fire and Explosion Hazards: None known Fire Fighting Equipment: Fire fighters and others exposed to products of combustion should wear self-contained breathing apparatus. Equipment should be thoroughly decontaminated after use. 6. ACCIDENTAL RELEASE MEASURES Observe all protection and safety precautions including use of rubber boots or overshoes when cleaning up spills -- see Exposure Controls/Personal Protection, Section 8.

3 GENESIS Hybridizing Agent Page 3 of 6 Liquid spills on floor or other impervious surfaces should be contained or diked and should be absorbed with attapulgite, bentonite or other absorbent clays. Collect contaminated absorbent, place in a plastic lined metal drum and dispose of in accordance with instructions provided under DISPOSAL CONSIDERATIONS. Thoroughly scrub floor with a strong industrial type detergent solution and rinse with water. Liquid spills that soak into the ground should be dug-up, placed in plastic-lined metal drums and disposed of in accordance with instructions provided under DISPOSAL CONSIDERATIONS. Leaking containers should be separated from non-leakers and either the container or its contents transferred to a plasticlined drum or other non-leaking container. Dispose of leaking container in accordance with instructions provided under disposal. Refer to Section 13 for disposal information and Section 15 for reportable quantity information. 7. HANDLING AND STORAGE HANDLING: Avoid contact with eyes or clothing. Wash thoroughly with soap and water after handling. Do not apply directly to water, to areas where surface water is present or to intertidal areas below the high water mark. Do not contaminate water when disposing of equipment washwaters. Emptied container retains vapor and product residue. Observe all labeled safeguards until container is cleaned, reconditioned, or destroyed. DO NOT REUSE THIS CONTAINER. Storage: Long term stability is being determined. However, shelf life stability of at least two years is expected. Store under cool, dry conditions (below 120 degrees F). Do not store under moist conditions. Do not store below 40 degrees F. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. 8. EXPOSURE CONTROLS/PERSONAL PROTECTION Eye Protection: Does not cause significant eye irritation or eye toxicity requiring special protection. Use good industrial practice to avoid eye contact. Skin Protection: Does not present significant skin concern requiring special protection. Respiratory Protection: This product is not likely to present an airborne exposure concern under normal use. Use NIOSH/MSHA approved respiratory protection equipment when airborne exposure is excessive. Consult respirator manufacturer to determine appropriate type equipment for given application. Observe respirator use limitations specified by NIOSH/MSHA or the manufacturer. Respiratory protection programs must comply with 29 CFR ' Ventilation: Provide natural or mechanical ventilation to minimize exposure. The use of local mechanical exhaust ventilation at sources of air contamination such as open process equipment is preferred.

TOXICOLOGICAL INFORMATION Data from Monsanto studies with this material are listed below: Oral LD 50 (Rat): Dermal LD 50 (Rat): Eye Irritation (Rabbit): Skin Irritation (Rabbit): Acute Inhalation (Rat, 4-hr LC 50 ): Sensitization (G. Pig): >5000 mg/kg, Practically Nontoxic (Category IV) >5000 mg/kg, Practically Nontoxic (Category IV) Slightly Irritating (Category III) Slightly Irritating (Category IV) >9.2 mg/l in air (Category IV) Negative COMPONENTS Data on Monsanto studies and from the available literature on the components of this material which have been identified under the criteria of the OSHA Hazard Communication Standard (29 CFR ' ) are discussed below: MON MON is considered slightly toxic (LD 50 > 5000) following single oral administration to rats. It is practically nontoxic (LD 50 > 5000) following dermal application to rats. It is moderately irritating in a rabbit eye study and nonirritating in a rabbit skin irritation study. MON was not a sensitizer in a dermal sensitization study with guinea pigs. No evidence of genotoxicity was observed in a standard battery of in vitro and in vivo studies. Subchronic studies have been conducted in rats, mice and dogs. No effects were noted in mice at a dietary concentration of 7,000 ppm (approximately 1000 mg/kg/day). Equivocal effects on weight gain and kidney weight were noted in rats at 20,000 ppm while no effects were noted at 5000 ppm (approximately 250 mg/kg/day). Excessive toxicity (mortality, vomiting, anemia, some indications of potential neurotoxicity, and histopathological lesions of the thymus and testes) were

5 GENESIS Hybridizing Agent Page 5 of 6 noted in dogs at 500 mg/kg/day. Some toxicity was also noted at 200 mg/kg/day but no effects were reported at 50 mg/kg/day. The chronic toxicity of MON has been investigated in a two-year study in rats and a one-year study in dogs. The no-observed effect level in both studies was 5 mg/kg/day. Kidney and liver toxicity was observed in rats; liver, thymus and testicular effects were noted in dogs. The two-year study in rats and an 18-month study in mice showed no evidence of treatment-related tumors. Neither maternal nor developmental toxicity was noted when MON was administered to pregnant rats at dose levels up to 1000 mg/kg/day. Excessive maternal toxicity but only slight developmental toxicity was noted when pregnant rabbits were administered MON at a dose level of 500 mg/kg/day. No maternal or developmental effects were noted in rabbits at 150 mg/kg/day. In a reproductive toxicity study, MON was fed to rats at high dose levels for two successive generations. There were no effects on mating or fertility at any dose level up to 20,000 ppm (1000 mg/kg/day). Decreased pup survival and a slight reduction in pup weight were observed only at the two highest dose levels of 5000 and 20,000 ppm, where there was also parental toxicity. The no-observed-effect-level was 500 ppm (45 mg/kg/day) for both parental and reproductive toxicity. Results from rat metabolism studies indicate that MON is well absorbed orally but rapidly excreted (primarily unchanged) via the urine. 12. ECOLOGICAL INFORMATION Acute aquatic and wildlife toxicity studies have been conducted with MON and MON (a 22% aqueous solution of MON 21200).
