As a result of the stock dividend, the number of outstanding shares of common stock increased by 0.7&amp;#160;million shares in 2012.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On August&amp;#160;31, 2011, the Company's Board of Directors declared a 5% stock dividend issued on October&amp;#160;14, 2011 to stockholders of record at the close of business on September&amp;#160;30, 2011. As a result of the stock dividend, the number of outstanding shares of common stock increased by 0.6&amp;#160;million shares in 2011.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;As the Company was in a deficit position for both 2012 and 2011, there was no recorded impact to the reported amounts of stockholders' equity in the accompanying consolidated balance sheet. All references to the number of common shares and per-share amounts included in these consolidated financial statements are restated based on the increased number of shares giving retroactive effect to the stock dividend to prior year amounts.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&lt;i&gt;2012 Public Common Stock Offering&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;

The Company also granted the underwriter in the offering an option for 45&amp;#160;days to purchase up to an additional 165,000 shares of common stock to cover over-allotments, if any. In connection with the underwriter's partial exercise of this option, the Company issued an additional 65,000 shares of common stock at an offering price to the public of $3.75 per share on May&amp;#160;22, 2012. The Company received net proceeds of $3.8&amp;#160;million after deducting underwriting discounts and other offering-related expenses of $0.6&amp;#160;million.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&lt;i&gt;2011 Warrant Call&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In August 2011, the Company called for redemption the outstanding warrants to purchase shares of common stock sold in the Company's initial public offering and private placement offering. Each warrant exercised in response to the call was exercised for 1.05 shares of common stock at a price of $2.38 per share as adjusted for the 2010 stock dividend. Any warrants not exercised expired on the last day of the exercise period and were redeemed at $.10 per underlying share of common stock. In connection with the warrant call, the Company issued 2,897,149 shares of common stock. The Company received aggregate net proceeds of $6.3&amp;#160;million upon such exercises including issuance costs of $0.6&amp;#160;million. The remaining unexercised warrants expired requiring the Company to pay the aggregate call amount of $3,000.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&lt;i&gt;Preferred Stock&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On November&amp;#160;7, 2012, the Company announced a "best efforts" public offering of 450,000 shares of its newly designated Series&amp;#160;A Preferred Stock. The Series&amp;#160;A Preferred Stock was offered at $23 per share. In November 2012, the Company issued 450,000 shares of Series&amp;#160;A Preferred Stock at $23 per share, receiving proceeds of $9.2&amp;#160;million after deducting underwriting discounts and other offering-related expenses of $1.2&amp;#160;million. The liquidation preference per share is $25. Cumulative dividends accrue and are paid in the amount of $2.72 per share each year, which is equivalent to 10.875% of the $25.00 liquidation preference per share. The dividend rate may increase under certain circumstances.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Holders of the Series&amp;#160;A Preferred Stock generally have no voting rights but have limited voting rights under certain circumstances. The Company may not redeem the Series&amp;#160;A Preferred Stock before December&amp;#160;1, 2017, except the Company is required to redeem the Series&amp;#160;A Preferred Stock following a "Change of Control," as defined. On and after December&amp;#160;1, 2017, the Company may, at its option, redeem the Series&amp;#160;A Preferred Stock, in whole or in part, by paying $25.00 per share, plus any accrued and unpaid dividends to the redemption date.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The change-in-control provision requires the preferred stock to be classified as temporary equity because, although deemed a remote possibility, a purchaser could acquire a majority of the voting power of the outstanding common stock without company approval, thereby triggering redemption. FASB ASC Topic 480-10-S99-3A,&lt;/font&gt; &lt;font size="2"&gt;&lt;i&gt;SEC Staff Announcement: Classification and Measurement of Redeemable Securities&lt;/i&gt;&lt;/font&gt;&lt;font size="2"&gt;, requires classification outside of permanent equity for redeemable instruments for which the redemption triggers are outside of the issuer's control. The assessment of whether the redemption of an equity security could occur outside of the issuer's control is required to be made without regard to the probability of the event or events that may result in the instrument becoming redeemable.&lt;/font&gt;&lt;/p&gt;
