Item 4.  Ownership.

Ownership is incorporated by reference to items 5-9 and 11 of the cover page of
each Reporting Person.

The percentage disclosed in item 11 of the cover page of each Reporting Person
is calculated based upon 51,750,000 shares of common stock reported to be
outstanding as of November 12, 2008 by the Issuer in its Form 10-Q for the
quarterly period ended September 30, 2008 filed with the Securities and
Exchange Commission on November 12, 2008.

As part of its initial public offering, the Issuer issued Units (the "Units"),
each Unit having a price of $10.00 and consisting of one ordinary share of
Common Stock, par value $0.0001 per share (the "Shares"), and one warrant,
each warrant entitling the holder to purchase one Share at a price of $7.50
(the "Warrants"). Each Warrant will become exercisable upon completion by the
Issuer of a business combination and will expire on October 17, 2011, or
earlier upon redemption. Because the Issuer has not completed a business
combination as of the filing date of this Schedule 13G, the shares of common
stock into which the Warrants are exercisable have not been included in the
number of shares beneficially owned by any Reporting Person.
