Item 4.01 Changes in Registrant’s Certifying Accountant.

On October 16, 2007, Marcum & Kliegman LLP resigned as the Registrant’s independent registered public accounting firm. The decision was not recommended or previously approved by the Registrant’s board of directors. The reports of Marcum & Kliegman LLP on the Registrant’s financial statements for the fiscal years ended December 31, 2006 and 2005 did not contain an adverse opinion or disclaimer of opinion and were not modified as to uncertainty, audit scope, or accounting principles, except the reports did contain an explanatory paragraph related to the Registrant’s ability to continue as a going concern. During the Registrant’s fiscal years ended December 31, 2006 and 2005, and the interim period from January 1, 2007 through October 16, 2007, there were no disagreements with Marcum & Kliegman LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Marcum & Kliegman LLP would have caused Marcum & Kliegman LLP to make reference to the subject matter of the disagreements in connection with its reports.
 
As of March 31, 2007, Marcum & Kliegman LLP had advised the Registrant that it identified certain deficiencies in the Registrant’s internal controls over financial reporting that constitute “material weaknesses.” The material weaknesses principally relate to the Registrant having limited segregation of duties within its accounting department, the need for the Registrant to strengthen its expertise with respect to the application of complex accounting pronouncements and the need for the Registrant to strengthen its expertise with respect to implementing a tax reporting structure to file, on a timely basis, Federal and state tax returns. The Registrant has attempted to remedy these deficiencies by engaging outside consultants and hiring internal personnel with the appropriate skills to address its ongoing accounting and finance needs.
 
The Registrant requested that Marcum & Kliegman LLP furnish it with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the Registrant’s statements in this Current Report on Form 8-K. A copy of the letter furnished by Marcum & Kliegman LLP in response to that request, dated October 22, 2007 is filed as Exhibit 16.1 to this Form 8-K.
