In addition, Lifebio/PCI will assume compliance responsibility for all regulatory and legal requirements by Brazilian national, state and local governments. Specific financial terms of the multi- year contract were not disclosed. L. Felippe C. De Castro, President and CEO of PCI stated, "We are extremely excited about this new venture with PURE Bioscience, and we strongly believe SDC will replace many toxic chemicals in multiple markets. SDC sets a new benchmark for efficacy and safety, and we think it will be the standard for many years to come." Lifebio is one member of the Grupo Sacchelli conglomerate. Several other companies owned by Grupo Sacchelli intend to incorporate SDC into their processes and/or products. Dr. Nilson Umberto Sacchelli Ribeiro, a Director of Grupo Sacchelli, added, "We have established joint development programs with Ministries of Health and Agriculture to conduct research and develop SDC-based products for use in healthcare as well as for use in farming and ranching and in food processing, packaging and distribution." Ribeiro continued, "Our early marketing efforts for SDC-based disinfectant target federal, state and municipal governments, hospitals, doctors' offices and clinics and other institutional users. We also plan to immediately present the technology to the food industry as a superior food contact antimicrobial and preservative. Additionally, we are currently exploring the use of SDC as an antimicrobial in cooling towers. Marketing across the country of Brazil has begun, and we have already converted approximately 25,000 square feet of a 100,000 square foot manufacturing facility to a state-of-the-art, large capacity blending and packaging operation for SDC- based products." Michael L. Krall, President and CEO of PURE Bioscience, commented, "Given the accelerating adoption of SDC technology in US applications, we are very excited about international interest in SDC. Brazil, as the fifth largest country in the world in both area and population, and the ninth largest economy, is a significant market because of its diversity and sophistication of industries and its recent implementation of progressive initiatives to protect the environment. We are confident that we have chosen excellent partners to commercialize our SDC technology in Brazil, and we are looking forward to a mutually lucrative relationship." About PCI International, Inc.
