Explanatory Note

The purpose of this Current Report on Form 8-K/A is to amend the Current Report on Form 8-K of Oragenics, Inc. (the “Company”), filed with the Securities and Exchange Commission on October 1, 2013 (the “Original Filing”) to correct a typographical error that was contained solely in the body of the Original Filing in Item 1.01 under the heading “The Stock Purchase and Issuance Agreement, as amended by the First Amendment”. Capitalized terms used herein have the meaning ascribed to them in the Original Filing.

The Original Filing reported, among other things, that pursuant to the SPIA, the Company issued to Intrexon 1,348,510 shares of the Company common stock (the “Technology Access Shares”), in consideration for the execution and delivery of the ECC and the Company sold to Intrexon 1.3 Million shares of the Company’s Common Stock at a price per share of $3.00 for gross proceeds of $3.9 Million. The correct number of Technology Access Shares issued to Intrexon is 1,348,000 shares as opposed to 1,348,510 shares.

Except as specifically amended herein, the Original Filing remains unchanged.

SIGNATURES

In accordance with the requirements of the Exchange Act, the registrant caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
