      Tiberius Acquisition Corporation, a Delaware corporation (“Maker”), promises to pay to the order of Lagniappe Ventures LLC or its registered
        assigns or successors in interest or order (“Payee”), the principal sum of up to One Million Dollars ($1,000,000.00) in lawful money of the United States of America, on the terms and conditions described
        below.  All payments on this Note (unless the full principal is converted pursuant to Section 16 below) shall be made by check or wire transfer of immediately available funds to such account as Payee may from time to time designate by written
        notice in accordance with the provisions of this Note.

      

      

      
        
          
            
              	 	
                      1.

                    	
                      Repayment. The principal balance of this Note shall be payable on the earliest to occur of (i) the date on which Maker consummates its
                        initial business combination, and (ii) the date that the winding up of Maker is effective (such date, the “Maturity Date”). The principal balance may not be prepaid without Payee’s written
                        consent.

                    


            

          

        

      

      

      

      
        
          
            
              	 	
                      2.

                    	
                      Interest. This Note shall be non-interest bearing.

                    


            

          

        

      

       

      
        
          
            
              	 	
                      3.

                    	
                      Drawdown Requests. Payee, in its sole and absolute discretion, may fund up to One Million Dollars ($1,000,000.00) for costs reasonably
                        related to Maker’s consummation of an initial business combination. The principal of this Note may be drawn down from time to time until the date on which Maker consummates its initial business combination, upon written request from
                        Maker to Payee (each, a “Drawdown Request”). Each Drawdown Request must state the amount to be drawn down, and must be in multiples of not less than Ten Thousand Dollars ($10,000) unless
                        agreed upon by Maker and Payee. Payee, in its sole discretion, shall fund each Drawdown Request no later than five (5) business days after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns
                        collectively under this Note shall not exceed One Million Dollars ($1,000,000.00). Once an amount is drawn down under this Note, it shall not be available for future Drawdown Requests even if prepaid. Except as set forth herein, no
                        fees, payments or other amounts shall be due to Payee in connection with, or as a result of, any Drawdown Request by Maker.

                    


            

          

        

      

      

      

      
        
          
            
              	 	
                      4.

                    	
                      Application of Payments. All payments received by Payee pursuant to this Note shall be applied first to the payment in full of any costs
                        incurred in the collection of any sum due under this Note, including (without limitation) reasonable attorney’s fees, and then to the reduction of the unpaid principal balance of this Note.

      6.    Remedies.

      

      

      (a)      Upon the occurrence of an Event of Default specified in Section 6(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) hereof, the unpaid principal balance of this Note and all other amounts payable hereunder,
        shall automatically and immediately become due and payable, in all cases without any action on the part of Payee.

      

      

      7.    Priorities. Maker and Payee acknowledge that Maker is the
          obligor under certain other promissory notes to Payee (the “Other Notes”). Notwithstanding anything to the contrary in the Other Notes, Maker and Payee agree that if the Maturity Date pursuant to this Note
          occurs for any reason, Maker shall repay all amounts due and payable under this Note and the Other Notes pari passu based upon the respective amounts due and payable under this Note and the Other Notes.

      

      

      8.    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 this 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 or personal property 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.

      

      

      9.    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.

       

      10.  Notices. All notices, statements or other documents which are
          required or contemplated by this Note shall be: (i) in writing and delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated in writing,
          (ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated in writing by such party and (iii) by electronic mail, to the electronic mail address most recently provided to such
          party or such other electronic mail address as may be designated in writing by such party.  Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if delivered personally, on the business day
          following receipt of written confirmation, if sent by facsimile or electronic transmission, one (1) business day after delivery to an overnight courier service or five (5) days after mailing if sent by mail.

      

      

      
        
          


      

      11.  Construction. THIS NOTE SHALL BE CONSTRUED AND ENFORCED IN
          ACCORDANCE WITH THE LAWS OF NEW YORK, WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS THEREOF.

      

      

      12.  Severability. Any provision contained in this Note which is
          prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or
          unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

       

      13.  Trust Waiver.  Notwithstanding anything herein to the contrary,
          Payee hereby waives any claim in or to any distribution of or from the trust account (the “Trust Account”) established in connection with Maker’s initial public offering (the “IPO”), and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any claim against the Trust Account for any reason whatsoever; provided, however, that on the Maturity Date, Maker shall repay the principal
          balance of this Note out of the proceeds released to Maker from the Trust Account.

      

      

      14.  Amendment; Waiver.  Any amendment hereto or waiver of any
          provision hereof may be made with, and only with, the written consent of Maker and Payee.

      

      

      15.  Assignment.  No assignment or transfer of this Note or any rights
          or obligations hereunder may be made by any party hereto (by operation of law or otherwise) without the prior written consent of the other party hereto and any attempted assignment without the required consent shall be void; provided, however, that the foregoing shall not apply to an affiliate of Payee who agrees to be bound to the terms of this Note.

      

      

      16.  Conversion.

      

      

      (a) At Payee’s option, at any time prior to payment in full of the principal balance of this Note, Payee may elect to convert all or any portion of the unpaid principal balance of
        this Note into that number of warrants issued by the Maker (the “Conversion Warrants”) equal to: (x) the portion of the principal amount of this Note being converted
        pursuant to this Section 17, divided by (y) $1.00, rounded up to the nearest whole number of warrants.

      

      

      (b) Upon any complete or partial conversion of the principal amount of this Note, (i) such principal amount shall be so converted and such converted portion of this Note shall
        become fully paid and satisfied, (ii) Payee shall surrender and deliver this Note, duly endorsed, to Maker or such other address which Maker shall designate against delivery of the Conversion Warrants, (iii) Maker shall promptly deliver a new duly
        executed Note to Payee in the principal amount that remains outstanding, if any, after any such conversion and (iv) in exchange for all or any portion of the surrendered Note, Maker shall, at the direction of Payee, deliver to Payee (or its members
        or their respective affiliates) (Payee or such other persons, the “Holders”) the Conversion Warrants, which shall bear such legends as are required, in the opinion of counsel to Maker or by any other
        agreement between Maker and Payee and applicable state and federal securities laws.

      

      

       (c) The Holders shall pay any and all issue and other taxes that may be payable with respect to any issue or delivery of the Conversion Warrants upon conversion of this Note
        pursuant hereto; provided, however, that the Holders shall not be obligated to pay any transfer taxes resulting from any transfer requested by the Holders in connection with any such conversion.

      

      

      
        
          
            17.  Registration Rights.

          

        

      

      

      

      (a) Reference is made to that certain Registration Rights Agreement between Maker and the parties thereto, dated as of March 15, 2018 (the “Registration

          Rights Agreement”). All capitalized terms used in this Section 18 shall have the same meanings ascribed to them in the Registration Rights Agreement.

      

      

      (b) The Holders shall be entitled to one Demand Registration, which shall be subject to the same provisions as set forth in Section 2.1 of the Registration Rights Agreement.

       

      

      
        
          


      

      (c) The Holders shall also be entitled to include the Conversion Warrants and shares underlying such warrants in Piggyback Registrations, which shall be subject to the same
        provisions as set forth in Section 2.2 of the Registration Rights Agreement; provided, however, that in the event that an underwriter advises Maker that the Maximum Number of Securities has been exceeded with respect to a Piggyback Registration,
        the Holders shall not have any priority for inclusion in such Piggyback Registration.

      

      

      (d) Except as set forth above, the Holders and Maker, as applicable, shall have all of the same rights, duties and obligations set forth in the Registration Rights Agreement.
