either (i) upon consummation of the Maker’s initial business combination out of the proceeds of the Trust Account released to the
Maker or (ii) at the Payee’s discretion, converted, in full or in part, upon consummation of the Maker’s business combination
into additional private units at a price of $10.00 per unit (the “Conversion”). Under no circumstances shall any individual,
including but not limited to any officer, director, employee or shareholder of the Maker, be obligated personally for any obligations

fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note.



 


	5.	Conversion and Repayment.

into private units, the Payee shall surrender this Note to the Maker and deliver to the Maker any documentation reasonably required by
