|  | During 2010, Cornerstone initiated a preferred stock offering, which ended on December 31, 2012. Specifics of the preferred stock offering were as follows:
| · | Issuance of 600,000 shares of Series A Convertible Preferred Stock at a price of $25.00 per share.
| · | The annual cash dividend on each share of Series A Preferred Stock is $2.50, which is equal to 10% of the original issue price of $25.00 per share, and is payable quarterly in arrears, if, as, and when declared on the 15th day of February, May, August, and November that immediately follows the end of the dividend period to which such dividends relate. Any dividend payable on shares of Series A Preferred Stock that is not declared by our board of directors or paid will accumulate.
| · · | Each share of Series A Preferred Stock will be convertible at the shareholder’s option at any time into five (5) shares of our common stock reflecting an initial conversion price of $5.00 per share of common stock. The shares of Series A Preferred Stock are also convertible at Cornerstone’s option, in whole or in part, into shares of Cornerstone’s common stock at the conversion rate, at any time on or after July 31, 2015, if the closing price of Cornerstone’s common stock equals or exceeds 150% of the conversion price on each of the thirty (30) consecutive trading days immediately preceding the date Cornerstone gives notice of its election to so convert. Subject to prior regulatory approval, each share of Series A Preferred Stock is redeemable by Cornerstone, in whole or in part, at any time after July 31, 2015, for a redemption price of $25.00 per share plus any accumulated and unpaid dividends.
At December 31, 2014 and 2013, the preferred stock dividends accumulated for each period, which were not declared, totaled $750,000 for each year.
