Item 4   Ownership:

  Provide the following information regarding the aggregate number and percentage of the class of securities of the issuer identified in Item 1.

(a) Amount Beneficially Owned

     As of the date of this filing, each Reporting Person may be deemed to be the beneficial owner of the following

(i)      20,500 shares of Common Stock owned outright by Millenco, L.P., a Delaware limited partnership (“Millenco”), which shares are held as part of the Company’s Units (“Units”). Each Unit consists of (1) one share of Common Stock, and (2) two Warrants (“Warrants”); and

(ii)     501,000 shares of Common Stock owned outright by Millenco.

     In addition to the Warrants exercisable into 41,000 shares of Common Stock, which are held as part of Units, Millenco owns Warrants exercisable into 84,000 shares of Common Stock. Each Warrant entitles the holder to purchase one share of the Company's Common Stock at a price of $5.00. Each Warrant will become exercisable on the later of the Company’s completion of a business combination and July 13, 2006, and will expire on July 12, 2009, or earlier upon redemption. As of the date of this filing, the Company has not announced the completion of a business combination.

    Millennium Management, L.L.C., a Delaware limited liability company ("Millennium Management"), is the general partner of Millenco, and consequently may be deemed to have voting control and investment discretion over securities owned by Millenco.  Israel A. Englander ("Mr. Englander") is the managing member of Millennium Management.  As a result, Mr. Englander may be deemed to be the beneficial owner of any shares deemed to be beneficially owned by Millennium Management. The foregoing should not be construed in and of itself as an admission by Millennium Management or Mr. Englander as to beneficial ownership of the shares owned by Millenco.

    Note: Millennium Partners, L.P., a Cayman Islands limited partnership ("Partners"), is a limited partner of Millenco. As a limited partner, Partners has no investment or voting control over Millenco or its securities positions.

(b) Percent of Class

    5.5% of the Company’s Common Stock (see Item 4(a) above), which percentage was calculated based on an aggregate amount of 9,550,000 shares of Common Stock outstanding as of August 1 2006, as reported in the Company's Quarterly Report on Form 10-QSB, dated as of August 14, 2006.
