PURE Bioscience Appoints New Board Members and Management Team

SAN DIEGO (August 13, 2013) – PURE Bioscience (OTCQB: PURE), creator of the patented silver dihydrogen citrate (SDC) antimicrobial, today announced a leadership reorganization beginning with the return of Dave Pfanzelter as chairman of the board of directors. Mr. Pfanzelter will also serve as interim chief executive officer while the company initiates the process of recruiting a new CEO. The company’s former chief financial officer, Peter C. Wulff, also agreed to return to the company to serve as both its CFO and chief operating officer. In addition, the company has appointed Gary Cohee to the board of directors.

Mr. Pfanzelter replaces Michael L. Krall, the company’s founder, who had served as chief executive officer, president and a member of the board of directors for more than 20 years since its inception in 1992.

“I am as excited as ever about the future of SDC and PURE Bioscience. I believe the SDC-based products are well positioned to make a difference in multiple industries, including the food service, food processing, hospital and personal care markets, by providing a safe and effective antimicrobial solution to dangerous pathogens. It’s been an honor to lead PURE Bioscience. I am proud of our team’s achievements and grateful for its commitment to bringing our amazing technology to fruition. I wish PURE Bioscience and its new management team the utmost success as they advance the company to the next stage of commercialization,” stated Mr. Krall.

“I am pleased to be named chairman of PURE’s board and serve as its interim CEO. I am confident in the company’s future prospects with our new management team who has laser focused discipline and experience to commercialize PURE’s technology and strengthen its financial condition,” said Mr. Pfanzelter, “In addition, we appreciate and recognize Michael Krall’s vision and creation of the intellectual property portfolio, product innovation and market strategy foundation upon which the company was built. Throughout his tenure, Mr. Krall transformed the company from its original phase as a pharmaceutical dispensing equipment company through acquisition of the unrefined version of SDC to the current point of commercialization of sophisticated SDC-based products. We thank Mr. Krall for his decades of hard work, dedication, tenacity and numerous other contributions as the founding visionary by developing the SDC technology platform as a unique and proprietary next-generation antimicrobial.”

“On behalf of Redwood Investment Group, I am pleased to have facilitated with key members of the management team the strategy and execution of Pure Bioscience’s transition,” said Mr. Tom Hemingway, President and CEO of Redwood Investment Group, “We are at an exciting inflection point of taking the business to the next level of development and look forward to shaping its future prospects.”
