        “Corporation”),
        and
        one warrant (“Warrant”).
        Each
        Warrant entitles the holder to purchase one (1) share of Common Stock for

        per share (subject to adjustment). The Common Stock and Warrants comprising
        the
        Units represented by this certificate shall commence separate trading on

over-allotment option, or (ii) its exercise in full; provided, that, in no
        event
        may the Common Stock and Warrants be traded separately until the Corporation
        has
        filed a Current Report on Form 8-K which includes an audited balance sheet
        reflecting its receipt of the proceeds of its initial public offering of
        securities, including any proceeds received from the exercise by the underwriter
        of its over-allotment option, if so exercised as of the date of the
        Corporation’s prospectus relating to its initial public offering. The terms of
        the Warrants are governed by a Warrant Agreement, dated as of [•],
        2007,
        between the Corporation and Continental Stock Transfer & Trust Company, as
        Warrant Agent, and are subject to the terms and provisions contained therein,
        all of which terms and provisions the holder of this certificate consents
        to by
        acceptance hereof. Copies of the Warrant Agreement are on file at the office
        of
        the Warrant Agent at 17 Battery Place, New York, New York 10004, and are
