Item 1.01.  Entry into a Material Definitive Agreement.

On October 29, 2014, the Company entered into an Exchange Agreement with Castle Creek Capital Partners IV, LP (“Castle Creek”).  Pursuant to the terms of the Exchange Agreement (the “Exchange Agreement”), Castle Creek would exchange 1,189,538 shares of the Company’s Series C Convertible Perpetual Preferred Stock having a liquidation preference of $3.25 per share (“Preferred Stock”) for shares of the Company’s common stock, no par value (“ Common Stock”), on a one-for-one exchange ratio basis.

On December 22, 2014, Castle Creek and the Company entered into a First Amendment to Exchange Agreement (“Amended Agreement”) to allow for an initial exchange of Preferred Stock whereby Castle Creek would exchange 840,841 shares of Preferred Stock for 840,841 shares of Common Stock which would result in Castle Creek beneficially owning no more than 9.99% of the Company’s outstanding shares of Common Stock (“Initial Closing”). The Initial Closing took place on December 24, 2014.

The Exchange Agreement was also amended to allow for a subsequent closing for the exchange of the remaining 348,697 shares of Preferred Stock at a mutually agreed upon date (“Subsequent Closing”) on or before March 31, 2015.
