    (as set forth on the Schedule of Borrowings attached hereto)

    

    

    Twin Ridge Capital Acquisition Corp., a Cayman Islands exempted company and blank check company (the “Maker”), promises to pay to the order of Twin Ridge Capital Sponsor, LLC, a Delaware limited liability company, or its registered assigns or successors in interest (the “Payee”), or order, the principal sum of up to Three Hundred Thousand U.S. dollars ($300,000) (as set forth on the Schedule of Borrowings
      attached hereto) 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
                  Note shall be payable by the Maker on the earlier of: (i) November 30, 2021 or (ii) the date on which Maker consummates an initial public offering of its securities (the “IPO”). 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.

            	
              Interest. No interest shall accrue on
                  the unpaid principal balance of this Note.

            


    

     

    
      	
              3.

            	
              Drawdown Requests. Maker and Payee agree that Maker may request up to Three Hundred Thousand Dollars ($300,000) for costs reasonably related to Maker’s initial public offering
                  of its securities. The principal of this Note may be drawn down from time to time prior to the earlier of: (i) November 30, 2021
                  or (ii) the date on which Maker consummates an initial public offering of its securities, 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 One Thousand Dollars ($1,000) unless agreed upon by Maker and Payee. Payee shall fund each Drawdown Request no later than one (1) business day after receipt of a Drawdown Request;
                  provided, however, that the maximum amount of drawdowns collectively under this Note is Three Hundred Thousand Dollars ($300,000). No fees, payments or other amounts shall be due to Payee in connection with, or as a result of, any
                  Drawdown Request by Maker.
