                the owner of
                __________________________________________________________________________________________
                Units.

            

    

     

    Each
      Unit
      (“Unit”) consists of one (1) ordinary share, par value $.001 per share
      (“Ordinary Share”), of HAMBRECHT ASIA ACQUISITION CORP., a Cayman Islands
      corporation (the “Company”), and one warrant (the “Warrant”). Each Warrant
      entitles the holder to purchase one (1) Ordinary Share for $6.00 per share
      (subject to adjustment). Each Warrant will become exercisable on the later
      of
      (i) the Company’s completion of an initial business combination with one or more
      target business or (ii) one (1) year from the date of the prospectus covering
      the Warrants and will expire unless exercised before 5:00 p.m., New York City
      Time, on ____________, 2012, or earlier upon redemption (the “Expiration Date”).
      The Ordinary Share and Warrant comprising the Units represented by this
      certificate may trade separately on the 45th
      day
      after
      the date of the prospectus unless the representative of the underwriters
      determines that an earlier date is acceptable; provided, however, in no event
      will the representative allow separate trading of the ordinary share and
      warrants until the Company files an audited balance sheet reflecting the
      Company’s receipt of the gross proceeds of the offering. The terms of the
      Warrants are governed by a Warrant Agreement, dated as of _______, 2007, between
      the Company 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
      available to any Warrant holder on written request and without cost. This
      certificate is not valid unless countersigned by the Transfer Agent and
      Registrar of the Company.
