Accordingly, information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted from the accompanying statements. These interim financial statements should be read in conjunction with the audited financial statements and related notes thereto, which are included in our Annual Report on Form 10-K for the year ended December 31, 2009 (the “2009 Form 10-K”).

(the “Common Stock Purchase Agreement”), from the calculation of diluted net loss per common share because such securities are antidilutive to the computation of net loss per share. As of June 30, 2010 and 2009, shares excluded from the computation of net loss per share were 22,639,752 and 31,029,660, respectively. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif"> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock Description containing the entire organization, consolidation and basis of presentation of financial statements disclosure.
