      (“Unit”) consists of one (1) ordinary share, par value $.0001 per share
      (“Ordinary Share”), of INDAS GREEN ACQUISITION CORPORATION, a Cayman Islands

      entitles the holder to purchase one (1) Ordinary Share for $5.00 per share
      (subject to adjustment). Each Warrant will become exercisable on the later
      of
      (i) the Company’s completion of an acquisition through a share capital exchange,
      share reconstruction or amalgamation, asset acquisition or other similar
      business combination (each a “Business Combination”) with a target business or
      (ii) [          ], 2009 [ONE YEAR
      FROM THE DATE OF THE FINAL PROSPECTUS RELATING TO THE COMPANY’S INITIAL PUBLIC
      OFFERING], and will expire unless exercised before 5:00 p.m., New York City
      Time, on [----], 2012 [FOUR YEARS FROM THE DATE OF THE FINAL PROSPECTUS RELATING
      THE COMPANY’S INITIAL PUBLIC OFFERING], or earlier upon redemption or
      liquidation of the Company’s trust account at [J.P. Morgan Chase Bank NA]
      maintained by Continental Stock Transfer & Trust Company acting as Trustee
      (the “Expiration Date”). 

    The
      Ordinary Share and Warrant comprising each Unit represented by this certificate
      are not separately transferable prior to the tenth (10th)
      day
      following the date of the earlier to occur: (i)  the expiration of the
      underwriters’ over-allotment option, (ii) its exercise in full, or
      (iii) the announcement by the representatives of the underwriters of their
      intention not to exercise all or any remaining portion of the over-allotment
      option, provided, however, in no event will the Ordinary Share and Warrant
      begin
      to trade separately until the Company files a report on Form 6-K containing
      an
      audited balance sheet reflecting its receipt of the gross proceeds of its
      initial public offering and issues a press release announcing when such separate
      trading will begin.
