 15.       Conversion.


 


(a) Notwithstanding

Units shall be identical to the units issued by the Maker to the Payee in a private placement upon consummation of the Maker’s
initial public offering. The Conversion Units and their underlying securities, and any other equity security of Maker issued or
issuable with respect to the foregoing by way of a stock dividend or stock split or in connection with a combination of shares,
recapitalization, amalgamation, consolidation or reorganization, shall be entitled to the registration rights set forth in Section
16 hereof.


 






     


     


    

 


(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) Payee shall surrender and deliver this Note, duly endorsed, to
Maker or such other address which Maker shall designate against delivery of the Conversion Units, (iii) Maker shall promptly deliver
a new duly executed Note to 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, Maker shall, at the direction of Payee, deliver to Payee (or its members
or their respective affiliates) (Payee or such other persons, the “Holders”) the Conversion Units, which shall
bear such legends as are required, in the opinion of counsel to Maker or by any other agreement between Maker and Payee and applicable
state and federal securities laws.


 


(c) The Holders shall
pay any and all issue and other taxes that may be payable with respect to any issue or delivery of the Conversion Units upon conversion
of this Note pursuant hereto; provided, however, that the Holders shall not be obligated to pay any transfer taxes resulting from
any transfer requested by the Holders in connection with any such conversion.


 


(d) The Conversion
Units shall not be issued upon conversion of this Note unless such issuance and such conversion comply with all applicable provisions
of law.


 


16.       Registration
Rights.
