The new additive package is similar to the current <br />package. A comparison of the two formulas can be found in, "ULTRAZOL° GA9058 Technical Document." The only <br />component change is where the detergent technology ratios are shifted slightly for a more effective product. The <br />current gasoline product is ULTRAZOL° 9888. The new gasoline product will be ULTRAZOL° GA9058. It is our <br />understanding once the current product sells down, the new additive can be dropped on top with no requirement to <br />pump out the tank or rinse. <br />Lubrizol is a manufacturer of additives commonly used in fuels and lubricants. Lubrizol conducts vigorous bench and <br />screening testing on all its products. Our manufacturing plants conduct assessments on the chemistries found in our <br />products to ensure they are compatible with all the materials the additive may encounter throughout our production <br />facilities. The components used to formulate ULTRAZOL° GA9058 have passed a wide range of fuel industry tests and <br />the chemistries have been in continuous use without reported problems to either fuel distribution or vehicle fuel <br />systems or any known harm to engine parts or materials. ULTRAZOL° GA9058 has been registered with US EPA in <br />accordance with 40 CFR 79 (EPA List of Certified Detergent Additives). <br />Attached are the current product SDS, the new product MSDS, and the ULTRAZOL Technical Document for your review. <br />Both chemicals have the same hazard classification based on the flash point and boiling point listed. Therefore, since no <br />
