      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;The

      accompanying condensed consolidated balance sheet as of

      December 31, 2012 has been derived from the Company&amp;#8217;s

      audited financial statements included in its Annual Report on

      Form 10-K for the year ended December 31, 2012. The

      accompanying unaudited condensed consolidated financial

      statements as of June 30, 2013 and for the three and six

      months ended June 30, 2013 and 2012 have been prepared in

      accordance with U.S. generally accepted accounting principles

      (&amp;#8220;GAAP&amp;#8221;) for interim financial information and

      pursuant to the rules and regulations of the Securities

      Exchange Commission (&amp;#8220;SEC&amp;#8221;). Certain information

      and note disclosures normally included in annual financial

      statements prepared in accordance with GAAP have been

      condensed or omitted pursuant to those rules and regulations,

      although the Company believes that the disclosures made are

      adequate to make the information not misleading. In the

      opinion of the Company&amp;#8217;s management, all adjustments

      (including normal recurring adjustments) necessary for a fair

      presentation for the periods presented have been reflected as

      required by Regulation S-X, Rule 10-01.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1827"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;The

      unaudited condensed consolidated statements of operations for

      the three and six months ended June 30, 2013 are not

      necessarily indicative of the results that may be expected

      for the entire year. These statements should be read in

      conjunction with the consolidated financial statements and

      related notes thereto included in the Company&amp;#8217;s Annual

      Report on Form 10-K for the year ended December&amp;#160;31,

      2012.&lt;/font&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;&amp;#160;&lt;b&gt;Use

      of Estimates&lt;/b&gt;&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1831"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;The

      preparation of financial statements in conformity with GAAP

      requires management to make estimates and assumptions that

      affect the reported amounts of assets and liabilities and

      disclosure of contingent assets and liabilities at the date

      of the financial statements and the reported amounts of

      revenue and expenses during the reporting period. Actual

      results could differ from those estimates.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; MARGIN: 0pt" id="PARA1833"&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1835"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;Basic

      and diluted loss per common share for all periods presented

      is calculated based on the weighted average common shares

      outstanding for the period. The following potentially

      dilutive securities were outstanding as of June 30, 2013 and

      2012 and were not included in the computation of dilutive

      loss per common share because the effect would have been

      anti-dilutive (in thousands):&lt;/font&gt;

      10-Q, for the quarters ended September 30, 2012, June 30,

      2012 and March 31, 2012 were changed by approximately
