entity (the “New Units”) equal to: (i) the portion of the principal amount of the Note being converted pursuant to this Section 3, divided by (ii) $10.00, rounded down to the nearest whole number. Each New Unit shall have
the same terms and conditions as private placement units issued simultaneously with the Maker’s initial public offering. 
 (b) Upon any complete or
partial conversion of the principal amount of this Note (i) such principal amount shall be so converted and such converted portion of this Note shall become fully paid and satisfied, (ii) the Payee shall surrender and deliver this Note,
duly endorsed, to Maker or such other address which Maker shall designate against delivery of the New Units, (iii) Maker shall promptly deliver a new duly executed Note to the Payee in the principal amount that remains outstanding, if any,
after any such conversion and (iv) in exchange for all or any portion of the surrendered Note described in Section 3(a), Maker shall deliver to Payee the New Units, which shall bear such legends as are required, in the opinion of counsel
to Maker or by any other agreement between Maker and the Payee and applicable state and federal securities laws. 
 (c) The Maker shall pay any and all
issue and other taxes that may be payable with respect to any issue or delivery of the New Units upon conversion of this Note pursuant hereto; provided, however, that the Payee shall pay any transfer taxes resulting from any transfer requested by
the Payee in connection with any such conversion.
