Condensed Consolidated Financial Statements at June 30, 2005 Statements of Stockholders` Deficit, page F-23 11. Refer to your response to comment 33. We note here and in your December 31, 2004 financial statements that it appears that you pushed the entire capital structure back over the years presented. Please note that the recapitalization should be pushed back and restated in a manner similar to a reverse acquisition, so the 4 million shares retained by the previous owners of the public company would not be outstanding for all periods presented. Please revise your presentation to reflect this treatment. (1) Business and Summary of Significant Accounting Policies, page F- 25 Formation and Business of the Company, page F-25 12. Please revise your discussion of the recapitalization to appropriately characterize it as such instead of the current characterization as a reverse merger. In addition, please provide a more detailed discussion related to this transaction. (5) Warrant Liability, page F-31 13.
