Item 3.02 UNREGISTERED SALES OF EQUITY SECURITIES As previously disclosed, on October 22, 2010, Dynasil Corporation of America (the "Company") determined to cause the mandatory conversion of all outstanding shares of its Series C 10% Cumulative Convertible Preferred Stock (the "Series C Preferred Stock")into shares of its Common Stock, $.0005 par value per share ("Common Stock"), at a conversion price of $2.50 per share, effective December 21, 2010 (the "Conversion Date"). As a result, as of the Conversion Date, all 5,256,000 shares of Series C Perferred Stock that had been outstanding are cancelled and have been automatically converted, without any action required on the part of the holders of Series C Preferred Stock, into an aggregate of 2,102,400 shares of Common Stock. The Company issued the shares of Common Stock pursuant to the conversion in reliance on the exemption from the federal registration requirements provided by Section 3(a)(9) of the Securities Act of 1933 (the "Securities Act"). Such shares are freely tradeable by persons who are not affiliates of the Company in compliance with applicable federal securities laws. As a result of foregoing, as of the date hereof, the Company has outstanding an aggregate of 14,834,542 shares of Common Stock and no outstanding preferred stock. Further, as each share of Series C Preferred Stock carried a 10% per annum dividend, the Company will no longer incur the annual dividend cost of $525,600 in cash or common stock dividends, as applicable. The shares of Series C Preferred Stock were originally sold at a price of $1.00 per share on July 1, 2008. The securities were offered and sold only to accredited investors within the meaning of Rule 501(a) under the Securities Act of 1933, as amended (the "Act"), in a transaction conducted pursuant to section 4(2) of the Act and Regulation D thereunder. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
