_____________is the registered holder of a warrant or warrants (the “Warrant” or “Warrants,” respectively), each whole Warrant entitling the holder thereof to purchase one ordinary share, par value $0.0001 per share (“Ordinary Shares”), of FUTUREWAVE ACQUISITION CORP. (the “Company”), at an exercise price of $11.50 per whole Ordinary Share, subject to adjustment as described in the warrant agreement (the “Warrant Agreement”), including in connection with certain issuances of ordinary shares or equity-linked securities below $9.20 per share in connection with the closing of the Company’s initial business combination, between the Company and Continental Stock Transfer & Trust Company (the “Warrant Agent”). The Warrants will become exercisable on the later of 30 days after the completion of the Company’s initial business combination and 12 months from the closing of the Company’s initial public offering, and will expire five years after the completion of the Company’s initial business combination or earlier upon liquidation, in each case as described in the Prospectus and the Warrant Agreement. In no event will the Company be required to net cash settle any Warrant.

Upon liquidation of the Company in the event an initial business combination is not consummated during the required period as identified in the Company’s Amended and Restated Memorandum and Articles of Association, as the same may be amended from time to time, the Warrant(s) shall expire and be worthless. The holder of a Warrant or Warrants shall have no right or interest of any kind in the Company’s trust account, as defined in the Prospectus.

Upon due presentment for registration of transfer of the Warrant Certificate at the office or agency of the Warrant Agent, a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee in exchange for this Warrant Certificate, without charge except for any applicable tax or other governmental charge.

The Company and the Warrant Agent may deem and treat the registered holder as the absolute owner of this Warrant Certificate, notwithstanding any notation of ownership or other writing hereon made by anyone, for the purpose of any exercise hereof, of any distribution to the registered holder, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

Holders of a Warrant or Warrants are not entitled to any of the rights of a shareholder of the Company.
