B. Riley Principal 250
Merger Corp. , a Delaware corporation and blank check company (the “Maker”), promises to pay to the order of B.
Riley Principal 250 Sponsor Co. LLC or its registered assigns or successors in interest (the
“Payee”), or order, the principal sum of up to Three Hundred Thousand Dollars ($300,000) 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) December 31, 2021 or (ii) the date on which Maker consummates an initial
public offering of its securities. 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) December
31, 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 Ten Thousand Dollars ($10,000) unless agreed upon by Maker and Payee. Payee 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 is Three Hundred Thousand Dollars ($300,000). Once an amount is drawn down under this Note, it shall not be available
for future Drawdown Requests even if prepaid. No fees, payments or other amounts shall be due to Payee in connection with, or as a result
of, any Drawdown Request by Maker. Notwithstanding the foregoing, 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 attorneys’ fees, and then to
the reduction of 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 amount due pursuant to this Note within five (5) business days of the date
specified above.


 


(b) Voluntary Bankruptcy,
Etc. The commencement by Maker of a voluntary case under any applicable bankruptcy, insolvency, reorganization, rehabilitation or
other similar law, or the consent by it to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian,
sequestrator (or other similar official) of 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 other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee,

its affairs, 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 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 or 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

11. 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.


  


12. Trust Waiver.  Notwithstanding
anything herein to the contrary, the Payee hereby waives any and all right, title, interest or claim of any kind (“Claim”)
in or to any distribution of or from the trust account to be established in which the proceeds of the initial public offering (the “IPO”)
to be conducted by the Maker (including the deferred underwriters discounts and commissions) and the proceeds of the sale of the units
to be issued in a private placement to occur prior to the closing of the IPO are to be deposited, as described in greater detail in the
registration statement and prospectus to be filed with the Securities and Exchange Commission in connection with the IPO, and hereby agrees
not to seek recourse, reimbursement, payment or satisfaction for any Claim against the trust account for any reason whatsoever.


 


13. Amendment; Waiver.  Any
