(the “Company”), creator of the patented non-toxic silver dihydrogen citrate (SDC) antimicrobial, completed a closing (the “Closing”) of a private placement financing (the “Private Placement Financing”) to accredited investors (the “Investors”). The Company raised $1.0 million in the Closing and issued an aggregate of 18,131,096 shares (collectively, the “Shares”) of the Company’s common stock at a purchase price of $0.0553 per share. The Shares issued in the Private Placement Financing were issued pursuant to a Securities Purchase Agreement (the “Securities Purchase Agreement”) entered into with the Investors. Mr. Tom Y. Lee, a member of the Company’s Board of Directors (the “Board”), invested approximately $700,000 directly and through his affiliates. In addition, Ivan Chen, a member of the Board, invested $27,650. The disinterested members of the Board approved the Private Placement Financing. The net proceeds to the Company from the Closing, after deducting fees and other offering expenses, are expected to be approximately $1.0 million.
