AMENDED AND RESTATED PROMISSORY NOTE


 


	Principal Amount: $150,000	 	Dated as of October 1, 2021


 


 


Mericsson Acquisition Corporation, a Cayman Islands exempted company
and blank check company (the “Maker”), promises to pay to the order of Mericsson Sponsor LLC, a Cayman Islands limited
liability company, or its registered assigns or successors in interest (the “Payee”), or order, the principal sum of
one hundred and fifty thousand U.S. dollars ($150,000) or such lesser amount as shall have been advanced by Payee to Maker and that shall
remain unpaid under this Note on the Maturity Date (as defined below) 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. This Note amends and restates in its entirety the Promissory Note of the Maker (“Original Note”) dated
February 5, 2021 in the principal sum of up to One Hundred and Fifty Thousand Dollars ($150,000) previously issued by the Maker to the
Payee but does not constitute a novation or extinguishment of the debt represented by the Original Note.


 


1. Principal.  The entire unpaid principal
balance of this Note shall be payable by the Maker on the earlier of:  (i) September 30, 2022, or (ii) the date on
which Maker consummates an initial public offering of its securities (such earlier date, the “Maturity Date”). 
The principal balance may be prepaid at any time. 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 or liabilities of the Maker hereunder.


 


2. Drawdown Requests. Maker and Payee agree
that Maker may request, from time to time, up to one hundred and fifty thousand U.S. dollars ($150,000) in drawdown0s under this Note
to be used for costs and expenses related to Maker’s formation and the proposed initial public offering of its securities (the “IPO”). 
The principal of this Note may be drawn down from time to time prior to the Maturity Date upon written request from Maker to Payee (each,
a “Drawdown Request”).  Each Drawdown Request must state the amount to be drawn down, and must not be an amount
less than Ten Thousand Dollars ($10,000).  Payee shall fund each Drawdown Request no later than three (3) business days after
receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns outstanding under this Note at any time may not
exceed one hundred and fifty thousand U.S. dollars ($150,000).  No fees, payments or other amounts shall be due to Payee in connection
with, or as a result of, any Drawdown Request by Maker.


 


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

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.

obtained by virtue hereof, or any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order desired
