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 BRC Inc., a Delaware public benefit corporation (the “Company”). Each whole 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 “Warrant 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 Warrant 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 whole Warrant is initially exercisable for one fully paid and
non-assessable share of Common Stock. 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 of the number of shares of Common Stock to be issued to the holder. The number of shares of Common Stock issuable
upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events as set forth in the Warrant Agreement

 

The initial Warrant Price per share of Common Stock for any Warrant
is equal to $11.50 per share. The Warrant Price is subject to adjustment upon the occurrence of certain events as 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 null and void. The Warrants may be redeemed, subject to certain conditions, as set forth in the Warrant Agreement.

 

     

     

    

 

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.

 

This Warrant Certificate shall be governed by and construed in accordance
with the internal laws of the State of New York.

[Form of Warrant Certificate]

 

[Reverse]

 

The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants entitling the holder on exercise to receive shares of Common Stock and are issued or to be issued pursuant
to a Warrant Agreement, dated as of February 25, 2021, as amended by the Warrant Assumption Agreement, dated as of February 9,
2022 (as so amended, the “Warrant Agreement”), duly executed and delivered by the Company to Continental Stock Transfer &
Trust Company, a New York corporation, as warrant agent (or successor warrant agent) (collectively, the “Warrant Agent”),
which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description
of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the
words “holders” or “holder” meaning the Registered Holders or Registered Holder, respectively) of
the Warrants. A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the Company. Defined terms
used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

 

Warrants may be exercised at any time during the Exercise Period set
forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering this Warrant
Certificate, with the form of election to purchase set forth hereon properly completed and executed, together with payment of the Warrant
Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in the Warrant Agreement) at the
designated office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised
shall be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee,
a new Warrant Certificate evidencing the number of Warrants not exercised.

 

Notwithstanding anything else in this Warrant Certificate or the Warrant
Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering the shares of Common
Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the shares of
Common Stock is current, except through “cashless exercise” as provided for in the Warrant Agreement.

 

The Warrant Agreement provides that upon the occurrence of certain
events the number of shares of Common Stock issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain
conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest in a share
of Common Stock, the Company shall, upon exercise, round down to the nearest whole number of shares of Common Stock to be issued to the
holder of the Warrant.

 

Warrant Certificates, when surrendered at the designated office of
the Warrant Agent by the Registered Holder thereof in person or by legal representative or attorney duly authorized in writing, may be
exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge,
for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants.

 

    

     

    

 

Upon due presentation for registration of transfer of this Warrant
Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate
a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations
provided in the Warrant Agreement, without charge except for any tax or other third-party charges imposed in connection therewith.

 

The Company and the Warrant Agent may deem and treat the Registered
Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing
hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for all other purposes,
and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate
entitles any holder hereof to any rights of a stockholder of the Company.

pursuant to which, on the terms and subject to the conditions set forth therein, among other things: (i) SilverBox will merge with
and into Merger Sub 1 (the “PubCo Merger”), with Merger Sub 1 being the surviving entity of the PubCo Merger, as a
result of which, among other things, (a) each SilverBox Class A Share outstanding immediately prior to the PubCo Merger will
no longer be outstanding and will automatically be converted into the right of the holder thereof to receive a PubCo Class A Share
on a one-for-one basis, (b) each SilverBox Class B Share outstanding immediately prior to the PubCo Merger will no longer be
outstanding and will automatically be converted into the right of the holder thereof to receive a combination of PubCo Class A Shares
and PubCo Class C Shares, and (c) each outstanding warrant (each, a “SilverBox Warrant”) to purchase SilverBox
Class A Shares outstanding immediately prior to the PubCo Merger will become a warrant of PubCo (each, a “PubCo Warrant”)
exercisable for PubCo Class A Shares on a one-for-one basis; (ii) Merger Sub 2 will merge with and into Blocker Corp (the “Blocker

WHEREAS, pursuant to the terms
and conditions of each of the Warrant Agreement and the Business Combination Agreement, upon the PubCo Merger Effective Time, each SilverBox
Warrant issued and outstanding immediately prior to the PubCo Merger Effective Time will automatically become a PubCo Warrant at the same
exercise price per share and on the same terms in effect immediately prior to the PubCo Merger Effective Time, and the rights and obligations
of SilverBox under the Warrant Agreement will be irrevocably assigned and assumed by PubCo; and

 

WHEREAS, as a result of this
Warrant Assumption Agreement, at the PubCo Merger Effective Time, PubCo will assume all of the obligations of SilverBox with respect to
each SilverBox Warrant, each of which will, at the PubCo Merger Effective Time, become a warrant to purchase PubCo Class A Shares
pursuant to the terms and conditions of the Warrant Agreement.

 

NOW, THEREFORE, in consideration
of the foregoing and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, SilverBox,
PubCo and the Warrant Agent hereby agree as follows:

 

		1.	Assignment and Assumption.

 

(a)            Upon
and subject to the occurrence of the PubCo Merger Effective Time, SilverBox hereby assigns, and PubCo hereby assumes, the rights and obligations
of SilverBox under the Warrant Agreement and the SilverBox Warrants (which shall be converted into PubCo Warrants), including the obligation
to issue PubCo Class A Shares upon the exercise of the PubCo Warrants, and PubCo hereby agrees to faithfully perform, satisfy and
discharge when due, the liabilities and obligations of SilverBox under the Warrant Agreement and the SilverBox Warrants (which shall be
converted into PubCo Warrants). As a result of the PubCo Merger, upon and subject to the occurrence of the PubCo Merger Effective Time,
each SilverBox Warrant will be automatically and irrevocably modified, pursuant to and in accordance with Section 4.4 of the Warrant
Agreement, with the effect that, at the PubCo Merger Effective Time, each SilverBox Warrant will be exchanged for a warrant to purchase
shares of PubCo Class A Shares pursuant to the terms and conditions of the Warrant Agreement.

 

    

     

    

 

(b)            PubCo
acknowledges and agrees that, subject to the terms of the Warrant Agreement, the SilverBox Warrants and this Warrant Assumption Agreement,
the Warrant Agreement and the SilverBox Warrants (which shall be converted into PubCo Warrants) shall continue in full force and effect
following the PubCo Merger Effective Time and that, from and after the PubCo Merger Effective Time, all of SilverBox’s obligations
thereunder shall be valid and enforceable as against PubCo and shall not be impaired or limited by the execution or effectiveness of this
Warrant Assumption Agreement.

 

(c)            This
Warrant Assumption Agreement is being executed and delivered pursuant and subject to the Warrant Agreement. Nothing in this Warrant Assumption
Agreement shall, or shall be deemed to, defeat, limit, alter, impair, enhance or enlarge any right, obligation, claim or remedy created
by the Warrant Agreement or any other document or instrument delivered pursuant to or in connection with it.

 

(d)            The
choice of law and jurisdiction provisions set forth in the Warrant Agreement and this Warrant Assumption Agreement shall continue to govern
the rights and obligations of the parties to the Warrant Agreement and this Warrant Assumption Agreement in all respects. The Company
hereby waives any objection to the jurisdiction provision governing the terms of the Warrant Agreement and this Warrant Assumption Agreement.

 

		2.	Miscellaneous.

 

(a)            Governing
Law and Jurisdiction. The validity, interpretation, and performance of this Warrant Assumption Agreement shall be governed in all
respects by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application
of the substantive laws of another jurisdiction. The Company hereby agrees that any action, proceeding or claim against it arising out
of or relating in any way to this Warrant Assumption Agreement shall be brought and enforced in the courts of the State of New York or
the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction. The Company hereby
waives any objection to such jurisdiction and that such courts represent an inconvenient forum. Any such process or summons to be served
