PROMISSORY
NOTE

 

	Principal
    Amount: $75,030.26	Dated
    as of December 8, 2022

 

Nova
Pulsar Holdings Limited (the “Maker”), promises to pay to the order of Nova Vision Acquisition Corp. or its registered
assigns or successors in interest (the “Payee”) the principal sum of Seventy-five-thousand, thirty U.S.

Dollars
and twenty-six cents ($75,030.26) in lawful money of the United States of America, on the terms and conditions described below. All payments
on this Note shall be made by check or wire transfer of immediately available funds or as otherwise determined by the Maker to such account
as the Payee may from time to time designate by written notice in accordance with the provisions of this Note.

 

	1.	Principal. The principal balance of this Promissory
Note (this “Note”) shall be payable promptly after the date on which the Maker consummates an initial business combination
(a “Business Combination”) with a target business (as described in its initial public offering prospectus dated August
5, 2021 (the “Prospectus”)). In the event that a Business Combination does not close on or prior to January 10, 2023,
as such deadline may be further extended, this Note shall be deemed to be terminated and no amounts will thereafter be due from Maker
to Payee under the terms hereof. The principal balance may not be prepaid without the consent of the Payee.
	 	 
	2.	Conversion Rights. The Payee has the right, but not
the obligation, to convert this Note, in whole or in part, into private units (the “Units”) of the Maker, as described in
the Prospectus, by providing the Maker with written notice of its intention to convert this note at least one business day prior to the
closing of a Business Combination. The number of Units to be received by the Payee in connection with such conversion shall be an amount
determined by dividing (x) the sum of the outstanding principal amount payable to such Payee by (y) $10.00.

 

	 	(a)	Fractional Shares. No fractional Units will be issued upon conversion of this Note. In lieu
of any fractional Units to which Payee would otherwise be entitled, Maker will pay to Payee in cash the amount of the unconverted principal
balance of this note that would otherwise be converted into such fractional share.
	 	 	 
	 	(b) 	Effect of Conversion. If the Maker timely receives notice of the Payee’s intention to
convert this note at least one business day prior to the closing of a Business Combination, this Note shall be deemed to be converted
on the date the Business Combination closes. At its expense, the Maker will, as soon as practicable after receiving this Note for cancellation
after the closing of a Business Combination (assuming receipt of timely notice of conversion), issue and deliver to Payee, at Payee’s
address set forth on the signature page hereto or such other address requested by Payee, a certificate or certificates for the number
of Units to which Payee is entitled upon such conversion (bearing such legends as are customary pursuant to applicable state and federal
securities laws), including a check payable to Payee for any cash amounts payable as a result of any fractional shares as described herein.

 

	3.	Interest. No interest shall accrue on the unpaid principal
balance of this Note.
	 	 
	4.	Application of Payments. All payments shall be applied
first to payment in full of any costs incurred in the collection of any sum due under this Note, including (without limitation) reasonable
attorney’s 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”):

 

	 	(a)	Failure
    to Make Required Payments. Failure by Maker to pay the principal of this Note within five (5) business days following the date
    when due.

 

    	1

     

    

 

	 	(b)	Voluntary
    Liquidation, Etc. The commencement by Maker of a proceeding relating to its bankruptcy, insolvency, reorganization, rehabilitation
    or other similar action, or the consent by it to the appointment of, or taking possession by, a receiver, liquidator, assignee, trustee,
    custodian, sequestrator (or other similar official) for 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.
	 	 	 
	 	(c)	Involuntary
    Bankruptcy, Etc. The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of maker
    in an involuntary case under any applicable bankruptcy, insolvency or similar law, for the appointing of a receiver, liquidator,
    assignee, custodian, trustee, sequestrator (or similar official) for Maker or for any substantial part of its property, or ordering
    the winding-up or liquidation of the affairs of Maker, and the continuance 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 hereunder, 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) and 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.

 

	7.	Waivers.
    Maker and all endorsers and guarantors of, and sureties for, this Note waive presentment for payment, demand, notice of dishonor,
    protest, and notice of protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted by Payee
    under the terms of this Note, and all benefits that might accrue to Maker by virtue of any present or future laws exempting any property,
    real or personal, or any part of the 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.	Notices.
    Any notice called for hereunder shall be deemed properly given if (i) sent by certified mail, return receipt requested, (ii)
    personally delivered, (iii) dispatched by any form of private or governmental express mail or delivery service providing receipted
