        The Subscription Agreement, dated as of August 9, 2019 (the “Subscription Agreement”), shall be amended as set forth below.  All capitalized terms used but not defined herein shall have the
          meanings set forth in the Subscription Agreement.

      

      
         

        

      

      
        WHEREAS, pursuant to the Subscription Agreement, the Company has, among other things, agreed to issue to the Subscriber concurrently with the Closing a number of warrants equal to the number of
          Initial Shares, on the terms and subject to the conditions contained therein;

      

      
        

        

      

      
        WHEREAS, as a condition to the closing of the Transaction, holders of at least 65% of those certain 34,500,000 outstanding public warrants of the SPAC (the “Public Warrants”), issued pursuant to
          that certain Warrant Agreement (as defined in the Merger Agreement), must approve and consent to the Warrant Amendment Proposal (as defined in the Merger Agreement), whereby the Warrant Agreement will be amended to remove the anti-dilution
          provisions contained in Section 4.1.2 of the Warrant Agreement relating to the payment of cash dividends, as set forth in Exhibit A;

      

      
        

        

      

      
        WHEREAS, to induce holders of the Public Warrants to approve and consent to the Warrant Amendment Proposal, the SPAC intends to seek to also amend the Warrant Agreement to provide for a cash
          payment of $1.60, payable in respect of each Public Warrant (the “Warrant Cash Payment”), and to reduce the number of shares of Common Stock for which each Public Warrant will be exercisable, in each case contingent upon the consummation of the
          Transaction; and

      

      
        

        

      

      
        WHEREAS, the parties desire to amend the terms of the Subscription Agreement to clarify (i) the exercise mechanics of the warrants to be issued to the Subscriber by the Company and (ii) that the

        Exhibit A

        Warrant Amendment Proposal

        

        

        
          The substantive text of the proposed Warrant Amendment is as follows:

        

        
          

          

          

          

        

        
          3.1           Warrant
                  Price.  Each Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the number of shares of Common
                Stock stated therein, at the price of $11.50 per share,, at such price equal to the Exercise Price described in Exhibit A for such Public
                  Warrants and Private Warrants, as applicable (each subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. 3.1); provided, however, that a Public Warrant may not be exercised for a fractional share, so that only a multiple of four Public Warrants
                  may be exercised at a given time.  The term “Warrant Price” as used in this Agreement shall mean the price per shareExercise Price (as specified in Exhibit A hereto) at which shares of Common Stock may be purchased at the time a Warrant is
                exercised. The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than twenty (20) Business Days, provided, that the Company shall provide at least
                twenty (20) days prior written notice of such reduction to Registered Holders of the Warrants and, provided further that any such reduction shall be identical among all of the Warrants.

          4.1.2          Extraordinary
                  Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or make a distribution in cash, securities or other assets to the holders of the
                Common Stock on account of such shares of Common Stock (or other shares of the Company’s capital stock into which the Warrants are convertible), other than (a) as described in subsection 4.1.1 above, (b) Ordinary Cash Dividends (as defined below), (cregular monthly, quarterly or other periodic cash dividends or cash distributions, (c) any other
                  cash dividend or distribution required to be paid in order for the Company to qualify or maintain its status as a real estate investment trust within the meaning of the Internal Revenue Code of 1986, as amended, or otherwise avoid the
                  imposition of U.S. federal and state income and excise taxes, so long as the Company qualifies or is seeking to maintain its status as a real estate investment trust at the time of such cash dividend or distribution, (d) to satisfy
                the redemption rights of the holders of the Common Stock in connection with a proposed initial Business Combination, (de) as a result
                of the repurchase of shares of Common Stock by the Company if a proposed Business Combination is presented to the stockholders of the Company for approval, (ef) to satisfy the redemption rights of the holders of Common Stock in connection with a stockholder vote to amend the Company’s amended and restated certificate of incorporation to modify the
                substance or timing of the Company’s obligation to redeem 100% of the public shares of Common Stock if the Company does not complete the Business Combination within the period set forth in 
                the Company’s amended and restated certificate of incorporation or (fg) in connection with the redemption of public shares of Common
                Stock upon the failure of the Company to complete its initial Business Combination and any subsequent distribution of its assets upon its liquidation (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the
                amount of cash and/or the fair market value (as determined by the Board, in good faith) of any securities or other assets paid on each share of Common Stock in respect of such Extraordinary Dividend.
                    For purposes of this subsection 4.1.2, “Ordinary Cash Dividends” means any cash
                    dividend or cash distribution which, when combined on a per share basis, with the per share amounts of all other cash dividends and cash distributions paid on the Common Stock during the 365-day period ending on the date of declaration
                    of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of shares of Common Stock issuable on exercise of each Warrant) does not
                    exceed $0.50 (being 5% of the offering price of the Units in the Offering).

          7.4.3          Mandatory Cash Distribution.  Notwithstanding anything contained in this Agreement to the contrary, at the Effective Time (as defined in the Merger
                  Agreement), each Public Warrant issued and outstanding immediately prior to the Effective Time shall, automatically and without any action by the Registered Holder thereof, be entitled to receive a cash distribution payable by or at the
                  direction of the Company as soon as reasonably practicable following the Effective Time, upon receipt of any documents as may reasonably be required by the Warrant Agent, in the amount of $1.60.

          Warrant Certificate

        

        
          

          

        

        
          This Warrant Certificate certifies that                    , or registered assigns, is the
              registered holder of warrant(s) evidenced hereby (the “Warrants” and each, a “Warrant”) to purchase shares of Class A common stock, $0.0001 par value per share (“Common Stock”), of Trinity Merger Corp., a Delaware corporation (the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and
              non-assessable shares of Common Stock as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise” as provided for in the Warrant Agreement) of the
              United States of America upon surrender of this Warrant Certificate and payment of the Exercise Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement.
              Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

        

        
          

          

        

        
          Each Public Warrant
            is initially exercisable for one-quarter of one
            fully paid and non-assessable share of Common Stock.  The Exercise Price per share of Common Stock for any Public Warrant is equal to $2.875 per one-quarter share ($11.50 per whole share); provided however, that a Public Warrant may not be exercised for a fractional share, so that only a
                multiple of four Public Warrants may be exercised at a given time.

          

          

          Each Private Warrant is exercisable for one fully paid and non-assessable share of Common
              Stock.  The Exercise Price per share of Common Stock for any Private Warrant is equal to $11.50 per share.

          

          

        

        
          No fractional shares will be issued upon exercise of any Warrant.  If, upon the exercise of Warrants, a holder would be entitled to receive a
            fractional interest in a share of Common Stock, the Company will, upon exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to the Warrant holder. The number of shares of Common
            Stock issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement.

        

        
           

            

        

        
          The initial Exercise Price per share of Common Stock for any Warrant is equal to $11.50 per share.
                The Exercise Price is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement.

        

        
          

          

        

        
          Subject to the conditions set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not
            exercised by the end of such Exercise Period, such Warrants shall become void.

        

        
          

          

        

        
          Reference is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions shall for
            all purposes have the same effect as though fully set forth at this place.

        

        
          

          

        

        This Warrant Certificate shall not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement.
