SCHEDULE 13D

Item 1.	Security and Issuer.
This statement relates to the common stock, par value $0.0001 per share (the “Common Stock”) of the Company, which shares are a constituent part of or trade separately from the Company’s Units (“Units”), of which each Reporting Person may be deemed to hold the number set forth on such respective Row 11. Each Unit consists of (i) one share of Common Stock and (ii) one Warrant (“Warrant”). Each Warrant entitles the holder to purchase one share of the Company’s Common Stock at a price of $5.00. Each Warrant became exercisable on the Company’s completion of a business combination on October 31, 2008, and will expire on March 4, 2011, or earlier upon redemption. This statement is being filed pursuant to Rules 13d-1 and 13d-5 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), solely to reflect the change between sole and shared voting and/or dispositive power of the Reporting Parties as the result of cross trades among the accounts managed by Dorset.
