The Company reported that the Board of Directors has been expanded to five members, with each member providing governance leadership consistent with its food safety business strategy.

Mr. Culver is the Co-Founder and Chief Executive Officer of Culver Franchising System, Inc., a quick-service restaurant chain with over 490 locations in 21 states, started almost 30 years ago. Mr. Culver has a long-standing track record of business building and community philanthropy.

“I am delighted to join PURE’s board and provide my strategic insights to develop, grow and build a sustainable business,” stated Craig Culver. “Our industry needs forward-thinking pathogen control technologies in food service to better protect our customers, employees and the environment. I believe that PURE’s SDC-based products provide the best potential solution to replace less effective and toxic legacy chemical products. Preliminary food service in-store test results of the SDC-based PURE Hard Surface disinfectant, compared to legacy products, are impressive.”

“Craig Culver’s entrepreneurial leadership and community contributions are exemplary of what PURE seeks in strategic board insight focused on food safety solutions,” stated Dave Pfanzelter, Chairman of the Board of Directors of PURE. “I am pleased to report we are entering the final stage of building a new Board of Directors that supports us in building PURE’s business as a new green-based paradigm in pathogen control into the food industry.”
