Oragenics, Inc. Finalizes Acquisition Of The iviGene Corporation

ALACHUA, Fla., Nov. 20 /PRNewswire-FirstCall/ -- Oragenics, Inc. announced today that it has acquired all of the outstanding shares of the iviGene Corporation, a privately held early-stage company focused on technologies related to infectious diseases, in a stock transaction for 185,186 shares of new Oragenics common stock. The transaction was unanimously approved by the boards of directors of both companies and the independent directors of Oragenics. Our Chief Scientific Officer and a director, Jeffrey Hillman, was a director and shareholder of iviGene and received 20,480 shares of Oragenics common stock for his shares of iviGene common stock. Our CEO, President and director, Robert T. Zahradnik, was an officer, director and former shareholder of iviGene. Dr. Zahradnik did not receive any shares of Oragenics common stock or any other consideration in this transaction. We are required to file a resale registration statement for the shares issued in connection with the transaction within ninety days.

Oragenics has had an exclusive license to specific applications of iviGene's patented IVIAT(TM) technology since February 2004. With this transaction, however, Oragenics has now acquired all of iviGene's assets, including issued and pending patents to two broad-based platform technologies. These technologies are capable of identifying gene and protein biomarkers for application to the improved diagnosis and treatment of a wide range of infectious diseases and cancers. Besides human diseases, other potential applications for these technologies include animal diseases, industrial and marine biofouling and plant diseases.

Dr. Robert Zahradnik, Oragenics' president and CEO, stated, "With the acquisition of the iviGene Corporation, Oragenics has significantly expanded its product development capabilities, especially in the company's focused areas of infectious disease and cancer. We believe that iviGene's proprietary technologies will position us to create significant future opportunities for Oragenics."
