Explanatory Note

This Current Report on Form 8-K/A is being filed as Amendment No. 2 to our Current Report on Form 8-K, which was originally filed with the Securities and Exchange Commission on October 27, 2005 and subsequently amended on September 29, 2006. Amendment No. 1 was filed to reflect the restatement of our financial statements for the period from April 12, 2005 (date of inception) through October 25, 2005 to reflect the classification and accounting for the warrants to purchase common stock associated with the units sold in our initial public offering.

This Amendment No. 2 does not amend the financial data as reflected in Amendment No. 1, and is filed for the sole purpose of conforming certain disclosures in Note B[5] to the financial statements with disclosures that will be reflected in the definitive proxy statement for our special meeting of stockholders at which our proposed acquisition of Advanced Technology Systems, Inc., among other proposals, will be voted upon.
