When used in the filings the words "anticipate", "believe", "estimate", "expect", "future", "intend", "plan" or the negative of these terms and similar expressions as they relate to Registrant or Registrant's management identify forward looking statements.

Should one or more of these risks or uncertainties materialize, or should the underlying assumptions prove incorrect, actual results may differ significantly from those anticipated, believed, estimated, expected, intended or planned.

Item 4. Changes in Registrant's Certifying Accountant On April 18, 2005, the Registrant engaged Sherb & Co. LLP as the Registrant's independent registered public accounting firm.

Manning's report on the Registrant's consolidated financial statements for the audit reports fiscal years ended December 31, 2004 and December 31, 2003 (the "Reports") did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles except as follows: In Manning's audit reports dated April 7, 2005 and March 25, 2004 for the Registrant's fiscal years ended December 31, 2004 and December 31, 2003, respectively, Manning indicated that: "The accompanying financial statements have been prepared assuming the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has not generated any revenue since inception and will need additional financing to sustain operations. These factors raise substantial doubt about the Company's ability to continue as a going concern. Management's plans in regard to these matters are also discussed in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty." During the Registrant's former fiscal years ended December 31, 2004 and December 30, 2003 and until Manning's resignation, there were no disagreements with Manning within the meaning of item 304 of regulation S-B or any matter of accounting principles or practices, financial disclosure, or auditing scope or procedure, which disagreements if not resolved to Manning`s satisfaction, would have caused Manning to make reference to the subject matter of the disagreements in connection with its reports. During the Registrant's former fiscal years ended December 31, 2004 and December 31, 2003, until Manning's resignation, there were no "reportable events" (as such term is defined in item 304(a)(1)(v) of regulation S-K). During the Registrant's two most recent fiscal years and any subsequent interim period prior to the engagement of Sherb & Co.

LLP, regarding either (i) the application of accounting principles to a specified transaction, either contemplated or proposed, or the type of audit opinion that might be rendered on the Registrant's financial statements or (ii) any matter that was either the subject of a "disagreement" or a "reportable event." The Registrant has requested Manning to review the disclosure contained herein and has asked Manning to furnish the Registrant with a letter addressed to the Commission containing any new information, clarification of the Registrant's expression of Manning's views, or the respects in which Manning does not agree with the statements contained herein.
