The Series D Convertible Preferred Stock is not mandatorily redeemable because it has no fixed redemption date, does not provide the holders with a general right to require redemption and does not otherwise contain an unconditional obligation requiring the Company to transfer cash or other assets. Accordingly, the Series D Convertible Preferred Stock is not classified as a liability under ASC 480.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">The Company determined that classification within permanent stockholders’ equity is appropriate. The cash preference payable upon an actual liquidation, dissolution or winding up represents an ordinary liquidation preference and does not require temporary-equity classification. In addition, a merger or consolidation that would constitute a deemed Liquidation Event requires substantive approval by the Company’s Board of Directors. The Board may withhold its approval and the holders of the Series D Convertible Preferred Stock do not control the Board or otherwise have the contractual ability to compel the Company to enter into such a transaction. Accordingly, the deemed-liquidation event is within the Company’s control for purposes of ASC 480-10-S99-3A. The Series D Convertible Preferred Stock is therefore classified within permanent stockholders’ equity, and the Company does not accrete its carrying amount to the 110% liquidation preference. The Company will reassess the classification if the relevant contractual, governance or control circumstances change.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify;
