      Class B Warrant (“Class B Warrant”) where every two Class B Warrants
      automatically convert into one Class A Warrant upon the Company’s consummation
      of its initial business combination. Each Class A Warrant entitles the holder
      to

      the Company files an audited balance sheet reflecting the Company’s receipt of
      the gross proceeds of the Company’s initial public offering. The terms of the
      Class A Warrants and Class B Warrants are governed by a Warrant Agreement,
