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.	Events of Default. The following shall constitute an event of default (“Event of Default”):

taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of Maker or for any substantial part of its property, or the making by it of any assignment for the benefit of creditors, or the
failure of Maker generally to pay its debts as such debts become due, or the taking of corporate action by Maker in furtherance of any of the foregoing.

of any such decree or order unstayed and in effect for a period of 60 consecutive days. 

  

	 	6.	Remedies. 

  

	 	(a)	Upon the occurrence of an Event of Default specified in Section 5(a) hereof, Payee may, by written notice to Maker, declare this Note to be due immediately and payable, whereupon the unpaid principal amount of this
Note, and all other amounts payable thereunder, shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived, anything contained herein or in the documents
evidencing the same to the contrary notwithstanding. 

  

	 	(b)	Upon the occurrence of an Event of Default specified in Sections 5(b) or 5(c), the unpaid principal balance of this Note, and all other sums payable with regard to this Note, shall automatically and immediately become
due and payable, in all cases without any action on the part of Payee.

proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing for any stay of execution, exemption from civil process, or extension of time for payment; and Maker agrees that any real estate that
may be levied upon pursuant to a judgment obtained by virtue hereof, on any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order desired by Payee. 


 

	 	8.	Unconditional Liability. Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or enforcement of the payment of this Note, and agrees that its liability shall be
unconditional, without regard to the liability of any other party, and shall not be affected in any manner by any indulgence, extension of time, renewal, waiver or modification granted or consented to by Payee, and consents to any and all extensions
of time, renewals, waivers, or modifications that may be granted by Payee with respect to the payment or other provisions of this Note, and agrees that additional makers, endorsers, guarantors, or sureties may become parties hereto without notice to
Maker or affecting Maker’s liability hereunder. 

  

	 	9.	Trust Waiver. Notwithstanding anything herein to the contrary, the Payee hereby waives any and all right, title, interest or claim of any kind (“Claim”) in or to any distribution of or
from the trust account to be established in which the proceeds of the IPO (including the deferred underwriters discounts and commissions) and the proceeds of the sale of the units issued in a private placement to occur prior to the effectiveness of
the IPO are to be deposited, as described in greater detail in the registration statement and prospectus to be filed with the Securities and Exchange Commission in connection with the IPO, and hereby agrees not to seek recourse, reimbursement,
