Units.

 

Each
Unit (“Unit”) consists of one Class A ordinary share, with a par value $0.0001 per share (“Class A Ordinary
Share”), of PROTONIQ Acquisition Corp., a Cayman Islands exempted company (the “Company”), one-half of one redeemable
warrant (“Warrant”), and one right to receive one-tenth (1/10) of one Class A ordinary share upon consummation of the initial
business combination. Each redeemable Warrant entitles the holder thereof to purchase one Class A Ordinary Share at a price of
$11.50 per full share (subject to adjustment), upon the later to occur of (i) 30 days after the Company’s completion of a merger,
share exchange, asset acquisition, share purchase, recapitalization, reorganization or other similar business combination with one or
more businesses or entities (a “Business Combination”) or (ii) one year from the closing of the Company’s initial public
offering and one right, each of which entitles the holder to receive one-tenth (1/10) of one Class A Ordinary Share upon consummation
of the Business Combination . The Class A Ordinary Shares, Warrants and Rights comprising the Units represented by this certificate
are not transferable separately prior to the fifty-second (52nd) day after the date of the prospectus relating to the Company’s
initial public offering, unless JonesTrading Institutional Services LLC (“JonesTrading”) determines that an earlier date
is acceptable, but in no event will the Class A Ordinary Shares and Warrants be traded separately until the Company files with
the Securities and Exchange Commission (the “SEC”) a current report on Form 8-K which includes an audited balance sheet reflecting
the receipt by the Company of the gross proceeds from its initial public offering including the proceeds received by the Company from
the exercise of the over-allotment option thereto, if the over-allotment option is exercised. If the over-allotment option is exercised
after the date of the prospectus, we will file an amendment to the Form 8-K or a new Form 8-K to provide updated financial information
to reflect the exercise of the over-allotment option. We will also include in the Form 8-K, or amendment thereto, or in a subsequent
Form 8-K, information indicating if the underwriters has allowed separate trading of the Class A Ordinary Shares and Warrants
prior to the 52nd day after the date of the prospectus.
