EX-4.4





 WARRANT AGREEMENT 

Dated [•], 2021 
 THIS
WARRANT AGREEMENT (this “Agreement”), dated [•], 2021, is by and between Build Acquisition Corp., a Delaware corporation (the “Company”), and Continental Stock Transfer & Trust Company, a
New York limited purpose trust company, as warrant agent (in such capacity, the “Warrant Agent”). 
 WHEREAS, it is
proposed that the Company enter into that certain Sponsor Warrants Purchase Agreement, with Build Acquisition Sponsor LLC, a Delaware limited liability company (the “Sponsor”), pursuant to which the Sponsor will purchase an
aggregate of 4,000,000 warrants (or up to 4,400,000 warrants depending on the extent to which the underwriters in the Offering (defined below) exercise their Over-allotment Option (as defined below)) simultaneously with the closing of the Offering
(and the closing of the Over-allotment Option, if applicable), bearing the legend set forth in Exhibit B hereto (the “Private Placement Warrants”) at a purchase price of $1.50 per Private Placement Warrant.
Each Private Placement Warrant entitles the holder thereof to purchase one shares of Common Stock (as defined below) at a price of $11.50 per share, subject to adjustment as described herein; and 

WHEREAS, in order to finance the Company’s transaction costs in connection with an intended initial merger, capital stock exchange, asset
acquisition, stock purchase, reorganization or similar business combination, involving the Company and one or more businesses (a “Business Combination”), the Sponsor or an affiliate of the Sponsor or certain of the
Company’s officers and directors may, but are not obligated to, loan the Company funds as the Company may require, of which up to $1,500,000 of such loans may be convertible into up to an additional 1,000,000 Private Placement Warrants at a
price of $1.50 per Private Placement Warrant; and 
 WHEREAS, the Company is engaged in an initial public offering (the
“Offering”) of units of the Company’s equity securities, each such unit comprised of one share of Common Stock and one-third of one Public Warrant (as defined below) (the
“Units”) and, in connection therewith, has determined to issue and deliver up to 7,666,667 redeemable warrants (including up to 1,000,000 redeemable warrants subject to the Over-allotment Option) to public investors in the
Offering (the “Public Warrants” and, together with the Private Placement Warrants, the “Warrants”). Each whole Warrant entitles the holder thereof to purchase one share of Class A common stock of
the Company, par value $0.0001 per share (“Common Stock”), for $11.50 per share, subject to adjustment as described herein. Only whole Warrants are exercisable. A holder of the Public Warrants will not be able to exercise any
fraction of a Warrant; and 
 WHEREAS, the Company has filed with the Securities and Exchange Commission (the
“Commission”) a registration statement on Form S-1, No. 333-[•], and a prospectus (the “Prospectus”), for the registration, under the Securities Act of
1933, as amended (the “Securities Act”), of the Units, the Public Warrants and the Common Stock included in the Units; and 

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with
the issuance, registration, transfer, exchange, redemption and exercise of the Warrants; and 
 WHEREAS, the Company desires to provide for
the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent and the holders of the Warrants; and 

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and
countersigned by or on behalf of the Warrant Agent (if a physical certificate is issued), as provided herein, the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Agreement. 

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows: 

1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the
Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement. 

2. Warrants. 

  
 1 













 2.1 Form of Warrant. Each Warrant shall initially be issued in registered form only.

 2.2 Effect of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant
to this Agreement, a certificated Warrant shall be invalid and of no effect and may not be exercised by the holder thereof. 
 2.3
Registration. 
 2.3.1 Warrant Register. The Warrant Agent shall maintain books (the “Warrant
Register”), for the registration of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants in book-entry form, the Warrant Agent shall issue and register the Warrants in the names
of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. Ownership of beneficial interests in the Public Warrants shall be shown on, and the transfer of such
ownership shall be effected through, records maintained by institutions that have accounts with The Depository Trust Company (the “Depositary”) (such institution, with respect to a Warrant in its account, a
“Participant”). 
 If the Depositary subsequently ceases to make its book-entry settlement system available for the
Public Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Public Warrants are not eligible for, or it is no longer necessary to have the Public Warrants available
in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver to the Warrant Agent for cancellation each book-entry Public Warrant, and the Company shall instruct the Warrant Agent to deliver to the
Depositary definitive certificates in physical form evidencing such Warrants (“Definitive Warrant Certificates”) which shall be in the form annexed hereto as Exhibit A. 

Physical certificates, if issued, shall be signed by, or bear the facsimile signature of, the Co-Chief
Executive Officer, Chief Financial Officer, Secretary or other principal officer of the Company. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person
signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance. 

2.3.2 Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may
deem and treat the person in whose name such Warrant is registered in the Warrant Register (the “Registered Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby, for the purpose of any
exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. 

2.4 Detachability of Warrants. The shares of Common Stock and Public Warrants comprising the Units shall begin separate trading on the
52nd day following the date of the Prospectus or, if such 52nd day is not on a day, other than a Saturday, Sunday or federal holiday, on which banks in New York City are generally open for normal business (a “Business Day”),
then on the immediately succeeding Business Day following such date, or earlier (the “Detachment Date”) with the consent of Cowen and Company, LLC and Allen & Company LLC, but in no event shall the shares of Common
Stock and the Public Warrants comprising the Units be separately traded until (A) the Company has filed a Current Report on Form 8-K with the Commission containing an audited balance sheet reflecting the
receipt by the Company of the gross proceeds of the Offering, including the proceeds then received by the Company from the exercise by the underwriters of their right to purchase additional Units in the Offering (the “Over-allotment
Option”), if the Over-allotment Option is exercised prior to the filing of the Current Report on Form 8-K, and (B) the Company issues a press release announcing when such separate trading
shall begin. 
 2.5 Fractional Warrants. The Company shall not issue fractional Warrants other than as part of the Units, each of
which is comprised of one shares of Common Stock and one-third of one whole Public Warrant. If, upon the detachment of Public Warrants from the Units or otherwise, a holder of Warrants would be entitled to
receive a fractional Warrant, the Company shall round down to the nearest whole number the number of Warrants to be issued to such holder. 

2.6 Private Placement Warrants. The Private Placement Warrants shall be identical to the Public Warrants, except that so long as they
are held by the Sponsor or any of its Permitted Transferees (as defined below) the Private Placement Warrants: (i) may be exercised for cash or on a “cashless basis,” pursuant to subsection 3.3.1(c) hereof,
(ii) including the shares of Common Stock issuable upon exercise of the Private 

  
 2 













 
Placement Warrants, may not be transferred, assigned or sold until thirty (30) days after the completion by the Company of an initial Business Combination, (iii) shall not be redeemable
by the Company pursuant to Section 6.1 hereof and (iv) shall only be redeemable by the Company pursuant to Section 6.2 if the Reference Value (as defined below) is less than $18.00 per share (subject to
adjustment in compliance with Section 4 hereof); provided, however, that in the case of (ii), the Private Placement Warrants and any shares of Common Stock issued upon exercise of the Private Placement Warrants may be
transferred by the holders thereof: 
 (a) to the Company’s directors or officers, any affiliates or family members of any of the
Company’s directors or officers, any members of the Sponsor or any affiliates of the Sponsor; 
 (b) in the case of an individual, by
gift to a member of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; 

(c) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; 

(d) in the case of an individual, pursuant to a qualified domestic relations order; 

(e) by private sales or transfers made in connection with the consummation of the Company’s Business Combination at prices no greater
than the price at which the securities were originally purchased; 
 (f) in the event of the Company’s liquidation prior to the
Company’s completion of its initial Business Combination; 
 (g) by virtue of the laws of Delaware or the Sponsor’s limited
liability company agreement, as amended, upon dissolution of the Sponsor; and 
 (h) in the event of the Company’s completion of a
liquidation, merger, stock exchange, reorganization or other similar transaction which results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property subsequent to
the completion of the Company’s initial Business Combination; 
 provided, however, that, in the case of clauses (a) through
(e), these permitted transferees (the “Permitted Transferees”) must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions in this Agreement. 

3. Terms and Exercise of Warrants. 

3.1 Warrant Price. Each whole Warrant shall 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, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section
3.1. The term “Warrant Price” as used in this Agreement shall mean the price per share (including in cash or by payment of Warrants pursuant to a “cashless exercise,” to the extent permitted hereunder) described
in the prior sentence 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 (unless otherwise required by the Commission, any national securities exchange on which the Warrants are listed or applicable law); 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. 

3.2 Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”)
(A) commencing on the later of: (i) the date that is thirty (30) days after the first date on which the Company completes a Business Combination, and (ii) the date that is twelve (12) months from the date of the closing of
the Offering, and (B) terminating at the earliest to occur of (x) 5:00 p.m., New York City time on the date that is five (5) years after the date on which the Company completes its initial Business Combination, (y) the
liquidation of the Company in accordance with the Company’s amended and restated certificate of incorporation, as amended from time to time, if the Company fails to complete a Business Combination, and (z) other than with respect to the
Private Placement Warrants then held by the Sponsor or its 

  
 3 













 
Permitted Transferees with respect to a redemption pursuant to Section 6.1 hereof or, if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in
compliance with Section 4 hereof), Section 6.2 hereof, 5:00 p.m., New York City time on the Redemption Date (as defined below) as provided in Section 6.4 hereof (the “Expiration
Date”); provided, however, that the exercise of any Warrant shall be subject to the satisfaction of any applicable conditions, as set forth in subsection 3.3.2 below, with respect to an effective
registration statement or a valid exemption therefrom being available. Except with respect to the right to receive the Redemption Price (as defined below) (other than with respect to a Private Placement Warrant then held by the Sponsor or its
Permitted Transferees in connection with a redemption pursuant to Section 6.1 hereof or, if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section
4 hereof), Section 6.2 hereof) in the event of a redemption (as set forth in Section 6 hereof), each Warrant (other than a Private Placement Warrant then held by the Sponsor or its Permitted Transferees in
the event of a redemption pursuant to Section 6.1 hereof or, if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof), Section
6.2 hereof) not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m. New York City time on the Expiration Date. The Company
in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided that the Company shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders
of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants. 
 3.3 Exercise of
Warrants. 
 3.3.1 Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant may be exercised by the
Registered Holder thereof by delivering to the Warrant Agent at its corporate trust department (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised, or, in the case of a Warrant represented by a book-entry, the
Warrants to be exercised (the “Book-Entry Warrants”) on the records of the Depositary to an account of the Warrant Agent at the Depositary designated for such purposes in writing by the Warrant Agent to the Depositary
from time to time, (ii) an election to purchase (“Election to Purchase”) any shares of Common Stock pursuant to the exercise of a Warrant, properly completed and executed by the Registered Holder on the reverse of the
Definitive Warrant Certificate or, in the case of a Book-Entry Warrant, properly delivered by the Participant in accordance with the Depositary’s procedures, and (iii) the payment in full of the Warrant Price for each share of Common Stock
as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the shares of Common Stock and the issuance of such shares of Common Stock, as follows: 

(a) in lawful money of the United States, in good certified check or wire payable to the Warrant Agent; 

(b) [Reserved]; 
 (c) with
respect to any Private Placement Warrant, so long as such Private Placement Warrant is held by the Sponsor or a Permitted Transferee, by surrendering the Warrants for that number of shares of Common Stock equal to (i) if in connection with a
redemption of Private Placement Warrants pursuant to Section 6.2 hereof, as provided in Section 6.2 hereof with respect to a Make-Whole Exercise (as defined below) and (ii) in all other scenarios the quotient
obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the excess of the “Sponsor Exercise Fair Market Value” (as defined in this subsection 3.3.1(c)) less the
Warrant Price by (y) the Sponsor Exercise Fair Market Value. Solely for purposes of this subsection 3.3.1(c), the “Sponsor Exercise Fair Market Value” shall mean the average last reported sale price of the shares of Common
Stock for the ten (10) trading days ending on the third (3rd) trading day prior to the date on which notice of exercise of the Private Placement Warrant is sent to the Warrant Agent; 

(d) as provided in Section 6.2 hereof with respect to a Make-Whole Exercise; or 

(e) as provided in Section 7.4 hereof. 

3.3.2 Issuance of Shares of Common Stock on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the
funds in payment of the Warrant Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall issue to the Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of shares of
Common Stock to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it on the register of members of the Company, and if such Warrant shall not have been exercised in full, a new book-entry position or
countersigned 

  
 4 













 
Warrant, as applicable, for the number of shares as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver any shares of
Common Stock pursuant to the exercise of a Warrant and shall have no obligation to settle such Warrant exercise unless a registration statement under the Securities Act with respect to the shares of Common Stock underlying the Public Warrants is
then effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section 7.4 or a valid exemption from registration is available. No Warrant shall be exercisable and the
Company shall not be obligated to issue shares of Common Stock upon exercise of a Warrant unless the shares of Common Stock issuable upon such Warrant exercise have been registered, qualified or deemed to be exempt from registration or qualification
under the securities laws of the state of residence of the Registered Holder of the Warrants. Subject to Section 4.6 of this Agreement, a Registered Holder of Warrants may exercise its Warrants only for a whole number of shares of
Common Stock. The Company may require holders of Public Warrants to settle the Warrant on a “cashless basis” pursuant to Section 7.4. If, by reason of any exercise of Warrants on a “cashless basis”, the holder of any
Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share of Common Stock, the Company shall round down to the nearest whole number, the number of shares of Common Stock to be issued to such holder.

 3.3.3 Valid Issuance. All shares of Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement
and the Company’s amended and restated certificate of incorporation shall be validly issued, fully paid and nonassessable. 
 3.3.4
Date of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for shares of Common Stock is issued shall for all purposes be deemed to have become the holder of record of such shares of Common Stock on the
date on which the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if
the date of such surrender and payment is a date when the share transfer books of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares of Common Stock at the close of
business on the next succeeding date on which the share transfer books or book-entry system are open. 
 3.3.5 Maximum Percentage. A
holder of a Warrant may notify the Company in writing in the event it elects to be subject to the provisions contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection
3.3.5 unless he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall not effect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the
extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially own in excess of 9.8% or such other amount as a holder may specify (the
“Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by
such person and its affiliates shall include the number of shares of Common Stock issuable upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock that would be
issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially owned by such person and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the
Company beneficially owned by such person and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained
herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”). For purposes of the Warrant, in determining the number of outstanding shares of Common Stock, the holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Annual
Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent
public announcement by the Company or (3) any other notice by the Company or Continental Stock Transfer & Trust Company, as transfer agent (in such capacity, the “Transfer Agent”), setting forth the number of
shares of Common Stock outstanding. For any reason at any time, upon the written request of the holder of the Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing to such holder the number of shares of Common
Stock then outstanding. In any case, the number of issued and outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the
date as of which such number of issued and outstanding shares of Common Stock was reported. By written notice to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to any
other percentage specified in such notice; provided, however, that any such increase shall not be effective until the sixty-first (61st) day after such notice is delivered to the Company.

 4. Adjustments. 

4.1 Stock Dividends. 

4.1.1 Split-Ups. If after the date hereof, and subject to the provisions of Section
4.6 below, the number of issued and outstanding shares of Common Stock is increased by a stock dividend of shares of Common Stock, or by a split-up of shares of Common Stock or other similar event,
then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased in proportion to such increase in the
issued and outstanding shares of Common Stock. A rights offering made to all or substantially all holders of shares of Common Stock entitling holders to purchase shares of Common Stock at a price less than the “Historical Fair Market
Value” (as defined below) shall be deemed a stock dividend of a number of shares of Common Stock equal to the product of (i) the number of shares of Common Stock actually sold in such rights offering (or issuable under any other equity
securities sold in such rights offering that are convertible into or exercisable for the shares of Common Stock) multiplied by (ii) one (1) minus the quotient of (x) the price per share of Common Stock paid in such rights offering divided
by (y) the Historical Fair Market Value. For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible into or exercisable for shares of Common Stock, in determining the price payable for shares of
Common Stock, there shall be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “Historical Fair Market Value” means the volume weighted average
price of the shares of Common Stock during the ten (10) trading day period ending on the trading day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular way, without
the right to receive such rights. No shares of Common Stock shall be issued at less than their par value. 
 4.1.2 Extraordinary
Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, pays to all or substantially all of the holders of Common Stock a dividend or make a distribution in cash, securities or other assets on account of such
shares of Common Stock (or other shares into which the Warrants are convertible), other than (a) as described in subsection 4.1.1 above, (b) Ordinary Cash Dividends (as defined below), (c) to satisfy the redemption rights
of the holders of Common Stock in connection with a proposed initial Business Combination, (d) to satisfy the redemption rights of the holders of Common Stock in connection with a stockholder vote to amend the Company’s second amended and
restated certificate of incorporation (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of the Company’s public
shares if it does not complete its initial Business Combination within the time period required by the Company’s second amended and restated certificate of incorporation, as amended from time to time, or (ii) with respect to any other
provision relating to stockholders’ rights or pre-initial Business Combination activity or (e) in connection with the redemption of public shares 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 Company’s board of directors (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 shares of Common Stock during the 365-day period ending on the date of declaration of such dividend or distribution to the extent it does not exceed $0.50 (which amount shall be 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). 

4.2 Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.6 hereof, the number of
issued and outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split, reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination,
reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease in issued and outstanding shares of Common Stock. 

  
 6 













 4.3 Adjustments in Exercise Price. Whenever the number of shares of Common Stock
purchasable upon the exercise of the Warrants is adjusted, as provided in subsection 4.1.1 or Section 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price
immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of
which shall be the number of shares of Common Stock so purchasable immediately thereafter. 
 4.4 Raising of the Capital in Connection
with the Initial Business Combination. If (x) the Company issues additional shares of Common Stock or equity-linked securities for capital raising purposes in connection with the closing of its initial Business Combination at an issue price
or effective issue price of less than $9.20 per share of Common Stock (with such issue price or effective issue price to be determined in good faith by the Board and, in the case of any such issuance to the Sponsor or its affiliates, without taking
into account any shares of Class B common stock, par value $0.0001 per share, of the Company held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate
gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the Company’s initial Business Combination on the date of the completion of the Company’s initial
Business Combination (net of redemptions), and (z) the volume-weighted average trading price of the Common Stock during the twenty (20) trading day period starting on the trading day prior to the day on which the Company consummates its
initial Business Combination (such price, the “Market Value”) is below $9.20 per share, the Warrant Price shall be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued
Price, the $10.00 per share redemption trigger price described in Section 6.2 shall be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption
trigger price described in Section 6.1 and Section 6.2 shall be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price. 

4.5 Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the issued and outstanding
shares of Common Stock (other than a change under Section 4.1 or Section 4.2 hereof or that solely affects the par value of such shares of Common Stock), or in the case of any merger or consolidation of the Company
with or into another corporation (other than a merger or consolidation in which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the issued and outstanding shares of Common Stock), or in
the case of any sale or conveyance to another corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the holders of the Warrants shall
thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the
exercise of the rights represented thereby, the kind and amount of shares, stock or other equity securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following
any such sale or transfer, that the holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s) immediately prior to such event (the “Alternative
Issuance”); provided, however, that (i) if the holders of Common Stock were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such merger
or consolidation, then the kind and amount of securities, cash or other assets constituting the Alternative Issuance for which each Warrant shall become exercisable shall be deemed to be the weighted average of the kind and amount received per share
by the holders of the Common Stock in such merger or consolidation that affirmatively make such election, and (ii) if a tender, exchange or redemption offer shall have been made to and accepted by the holders of Common Stock (other than a
tender, exchange or redemption offer made by the Company in connection with redemption rights held by stockholders of the Company as provided for in the Company’s second amended and restated certificate of incorporation or as a result of the
repurchase of shares of Common Stock by the Company if a proposed initial Business Combination is presented to the stockholders of the Company for approval) under circumstances in which, upon completion of such tender or exchange offer, the maker
thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) of which such maker is a part, and together with any affiliate or associate of such maker (within the
meaning of Rule 12b-2 under the Exchange Act) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule
13d-3 under the Exchange Act) more than 50% of the issued and outstanding shares of Common Stock, the holder of a Warrant shall be entitled to receive as the Alternative Issuance, the highest amount of cash,
securities or other property to which such holder would actually have been entitled as a stockholder if such Warrant holder had exercised the Warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the shares
of Common Stock held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments


  
 7 













 
provided for in this Section 4; provided further that if less than 70% of the consideration receivable by the holders of Common Stock in the applicable event is
payable in the form of common stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter
market, or is to be so listed for trading or quoted immediately following such event, and if the Registered Holder properly exercises the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable
event by the Company pursuant to a Current Report on Form 8-K filed with the Commission, the Warrant Price shall be reduced by an amount (in dollars) equal to the difference of (i) the Warrant Price in
effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) (but in no event less than zero) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant
Value” means the value of a Warrant immediately prior to the consummation of the applicable event based on the Black-Scholes Warrant Model for a Capped American Call on Bloomberg Financial Markets (assuming zero dividends)
(“Bloomberg”). For purposes of calculating such amount, (i) Section 6 of this Agreement shall be taken into account, (ii) the price of each share of Common Stock shall be the volume weighted average
price of the Common Stock during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event, (iii) the assumed volatility shall be the 90 day volatility obtained from the HVT function on
Bloomberg determined as of the trading day immediately prior to the day of the announcement of the applicable event and (iv) the assumed risk-free interest rate shall correspond to the U.S. Treasury rate for a period equal to the remaining term
of the Warrant. “Per Share Consideration” means (i) if the consideration paid to holders of Common Stock consists exclusively of cash, the amount of such cash per share of Common Stock, and (ii) in all other cases,
the volume weighted average price of the Common Stock during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event. If any reclassification or reorganization also results in a change in
shares of Common Stock covered by subsection 4.1.1, then such adjustment shall be made pursuant to subsection 4.1.1 or Sections 4.2, 4.3 and this Section 4.4. The provisions of
this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. In no event shall the Warrant Price be reduced to less than the par value per share
issuable upon exercise of such Warrant. 
 4.6 Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number
of shares issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of
shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Sections
4.1, 4.2, 4.3, 4.4, 4.5 or 4.9, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder in
the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event. 

4.7 No Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue
fractional shares upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a
share, the Company shall, upon such exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to such holder. 

4.8 Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and
Warrants issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrants initially issued pursuant to this Agreement; provided, however, that the Company may at any
time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an
outstanding Warrant or otherwise, may be in the form as so changed. 
 4.9 Other Events. In case any event shall occur affecting the
Company as to which none of the provisions of the preceding subsections of this Section 4 are strictly applicable, but which would require an adjustment to the terms of the Warrants in order to (i) avoid an adverse impact on
the Warrants and (ii) effectuate the intent and purpose of this Section 4, then, in each such case, the Company shall appoint a firm of independent registered public accountants, investment banking or other appraisal firm of
recognized national standing, which shall give its opinion as to whether or not any adjustment to the rights represented by the Warrants is necessary to effectuate the intent and purpose of this Section 4 and, if they determine that
an adjustment is necessary, the terms of such adjustment; provided, however, that under no circumstances shall the Warrants be adjusted pursuant to this Section 4.9 as a result of any issuance of securities
in connection with a Business Combination. The Company shall adjust the terms of the Warrants in a manner that is consistent with any adjustment recommended in such opinion.

 5. Transfer and Exchange of Warrants. 

5.1 Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the
Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate
number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. In the case of certificated Warrants, the Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon request.

 5.2 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for
exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of
Warrants; provided, however, that except as otherwise provided herein or with respect to any Book-Entry Warrant, each Book-Entry Warrant may be transferred only in whole and only to the Depositary, to another nominee of the
Depositary, to a successor depository, or to a nominee of a successor depository; provided further, however that in the event that a Warrant surrendered for transfer bears a restrictive legend (as in the case of the
Private Placement Warrants), the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating
whether the new Warrants must also bear a restrictive legend. 
 5.3 Fractional Warrants. The Warrant Agent shall not be required to
effect any registration of transfer or exchange which shall result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant, except as part of the Units. 

5.4 Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants. 

5.5 Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the
terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of
the Company for such purpose. 
 5.6 Transfer of Warrants. Prior to the Detachment Date, the Public Warrants may be transferred or
exchanged only together with the Unit in which such Warrant is included, and only for the purpose of effecting, or in conjunction with, a transfer or exchange of such Unit. Furthermore, each transfer of a Unit on the register relating to such Units
shall operate also to transfer the Warrants included in such Unit. Notwithstanding the foregoing, the provisions of this Section 5.6 shall have no effect on any transfer of Warrants on and after the Detachment Date. 

6. Redemption. 
 6.1
Redemption of Warrants for Cash. Subject to Section 6.6 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of the Company, at any time during the Exercise Period, at the office of the Warrant
Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.4 below, at a Redemption Price of $0.01 per Warrant, provided that (a) the Reference Value equals or exceeds $18.00 per
share (subject to adjustment in compliance with Section 4 hereof) and (b) there is an effective registration statement covering the issuance of the shares of Common Stock issuable upon exercise of the Warrants, and a current
prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in Section 6.4 below). 

6.2 Redemption of Warrants for shares of Common Stock. Subject to Section 6.6 hereof, not less than all of the
outstanding Warrants may be redeemed, at the option of the Company, at any time during the Exercise Period, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section
6.4 below, at a Redemption Price of $0.10 per Warrant, provided that (i) the Reference Value equals or exceeds $10.00 per share (subject to adjustment in compliance with Section 4 hereof) and
(ii) if 

  
 9 













 
the Reference Value is less than $18.00 per share (subject to adjustment in compliance with Section 4 hereof), the Private Placement Warrants are also concurrently called for
redemption on the same terms as the outstanding Public Warrants. During the 30-day Redemption Period in connection with a redemption pursuant to this Section 6.2, Registered Holders of the Warrants
may elect to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1 and receive a number of shares of Common Stock determined by reference to the table below, based on the Redemption Date (calculated
for purposes of the table as the period to expiration of the Warrants) and the “Redemption Fair Market Value” (as such term is defined in this Section 6.2) (a “Make-Whole Exercise”). Solely for purposes
of this Section 6.2, the “Redemption Fair Market Value” shall mean the volume weighted average price of the Common Stock during the ten (10) trading days immediately following the date on which notice of
redemption pursuant to this Section 6.2 is sent to the Registered Holders. In connection with any redemption pursuant to this Section 6.2, the Company shall provide the Registered Holders with the Redemption Fair Market
Value no later than one (1) Business Day after the ten (10) trading day period described above ends.

 The exact Redemption Fair Market Value and Redemption Date may not be set forth in the table above, in which
case, if the Redemption Fair Market Value is between two values in the table or the Redemption Date is between two redemption dates in the table, the number of shares of Common Stock to be issued for each Warrant exercised in a Make-Whole Exercise
shall be determined by a straight-line interpolation between the number of shares set forth for the higher and lower Redemption Fair Market Values and the earlier and later redemption dates, as applicable, based on a
365- or 366-day year, as applicable. 
 6.3 The stock prices
set forth in the column headings of the table above shall be adjusted as of any date on which the number of shares issuable upon exercise of a Warrant or the Exercise Price is adjusted pursuant to Section 4 hereof. If the number of
shares issuable upon exercise of a Warrant is adjusted pursuant to Section 4 hereof, the adjusted stock prices in the column headings shall equal the stock prices immediately prior to such adjustment, multiplied by a fraction, the
numerator of which is the number of shares deliverable upon exercise of a Warrant immediately prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a Warrant as so adjusted. The number of shares
in the table above shall be adjusted in the same manner and at the same time as the number of shares issuable upon exercise of a Warrant. If the Exercise Price is adjusted, (a) in the case of an adjustment pursuant to Section
4.4 hereof, the adjusted stock prices in the column headings shall equal the stock prices immediately prior to such adjustment multiplied by a fraction, the numerator of which is the higher of the Market Value and the Newly Issued Price and
the denominator of which is $10.00 and (b) in the case of an adjustment pursuant to Section 4.1.2 hereof, the adjusted stock prices in the column headings shall equal the stock prices immediately prior to such adjustment less
the decrease in the Exercise Price pursuant to such Exercise Price adjustment. In no event shall the Warrants be exercisable in connection with a Make-Whole Exercise for more than 0.361 shares of Common Stock per Warrant (subject to adjustment).

 6.4 Date Fixed for, and Notice of, Redemption; Redemption Price; Reference Value. In
the event that the Company elects to redeem the Warrants pursuant to Sections 6.1 or 6.2, the Company shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be
mailed by first class mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (the period lasting from such time until the Redemption Date, the “30-day
Redemption Period”) to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in the manner herein provided shall be conclusively presumed to have
been duly given whether or not the Registered Holder received such notice. As used in this Agreement, (a) “Redemption Price” shall mean the price per Warrant at which any Warrants are redeemed pursuant
to Sections 6.1 or 6.2 and (b) “Reference Value” shall mean the last reported sales price of the shares of Common Stock for any twenty (20) trading days within the thirty (30) trading-day period ending on the third (3rd) trading day prior to the date on which notice of the redemption is given. 

6.5 Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance
with Section 6.2 of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.4 hereof and prior to the Redemption Date. On and after the Redemption Date, the
record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price. 
 6.6
Exclusion of Private Placement Warrants. The Company agrees that (a) the redemption rights provided in Section 6.1 hereof shall not apply to the Private Placement Warrants if at the time of the redemption such Private
Placement Warrants continue to be held by the Sponsor or its Permitted Transferees and (b) if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof), the redemption
rights provided in Section 6.2 hereof shall not apply to the Private Placement Warrants if at the time of the redemption such Private Placement Warrants continue to be held by the Sponsor or its Permitted Transferees. However, once
such Private Placement Warrants are transferred (other than to Permitted Transferees in accordance with Section 2.6 hereof), the Company may redeem the Private Placement Warrants pursuant to Section
6.1 or 6.2 hereof, provided that the criteria for redemption are met, including the opportunity of the holder of such Private Placement Warrants to exercise the Private Placement Warrants prior to redemption pursuant
to Section 6.5 hereof. Private Placement Warrants that are transferred to persons other than Permitted Transferees shall upon such transfer cease to be Private Placement Warrants and shall become Public Warrants under this
Agreement, including for purposes of Section 9.8 hereof. 
 7. Other Provisions Relating to Rights of Holders of
Warrants. 
 7.1 No Rights as Stockholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a
stockholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders
or the election of directors of the Company or any other matter. 
 7.2 Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant
is lost, stolen, mutilated, or destroyed, the Company and the Warrant Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue
a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen,
mutilated, or destroyed Warrant shall be at any time enforceable by anyone. 
 7.3 Reservation of Shares of Common Stock. The Company
shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement. 

7.4 Registration of Shares of Common Stock; Cashless Exercise at Company’s Option. 

7.4.1 Registration of the shares of Common Stock. The Company agrees that as soon as practicable, but in no event later than fifteen
(15) Business Days after the closing of its initial Business Combination, it shall use its commercially reasonable efforts to file with the Commission a registration statement for the registration, under the Securities Act, of the shares of
Common Stock issuable upon exercise of the Warrants. The Company shall use its commercially reasonable efforts to cause the same to become effective within sixty (60) Business Days following the closing of its initial Business Combination and
to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration or 

  
 11 













 
redemption of the Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared effective by the sixtieth (60th) Business Day following the closing of the Business Combination, holders of the Warrants shall have the right, during the period beginning on the sixty-first (61st) Business Day after the closing of the Business Combination and ending upon such registration statement being declared effective by the Commission, and during any other period when the Company shall
fail to have maintained an effective registration statement covering the issuance of the shares of Common Stock issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless basis,” by exchanging the Warrants (in
accordance with Section 3(a)(9) of the Securities Act or another exemption) for that number of shares of Common Stock equal to the lesser of (A) the quotient obtained by dividing (x) the product of the number of shares of Common Stock
underlying the Warrants, multiplied by the excess of the “Fair Market Value” (as defined below) less the Warrant Price by (y) the Fair Market Value and (B) 0.361. Solely for purposes of this subsection 7.4.1,
“Fair Market Value” shall mean the volume-weighted average price of the shares of Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the date that notice of exercise is
received by the Warrant Agent from the holder of such Warrants or its securities broker or intermediary. The date that notice of “cashless exercise” is received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In
connection with the “cashless exercise” of a Public Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating
that (i) the exercise of the Warrants on a “cashless basis” in accordance with this subsection 7.4.1 is not required to be registered under the Securities Act and (ii) the shares of Common Stock issued upon such
exercise shall be freely tradable under United States federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Securities Act) of the Company and, accordingly, shall not be required to bear a
restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of doubt, unless and until all of the Warrants have been exercised or have expired, the Company shall continue to be obligated to comply with its registration
obligations under the first three sentences of this subsection 7.4.1. 
 7.4.2 Cashless Exercise at Company’s
Option. If the shares of Common Stock are at the time of any exercise of a Public Warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the
Securities Act, the Company may, at its option, (i) require holders of Public Warrants who exercise Public Warrants to exercise such Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act
as described in subsection 7.4.1 and (ii) in the event the Company so elects, the Company shall (x) not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of
the shares of Common Stock issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary, and (y) use its commercially reasonable efforts to register or qualify for sale the shares of Common Stock issuable
upon exercise of the Public Warrant under applicable blue sky laws to the extent an exemption is not available. 
 8. Concerning the
Warrant Agent and Other Matters. 
 8.1 Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges
that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants
or such shares. 
 8.2 Resignation, Consolidation, or Merger of Warrant Agent. 

8.2.1 Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and
be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company
shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by
the Warrant Agent or by the holder of a Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New
York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation or other entity organized and existing under the laws of the
State of New York, in good standing and having its principal office in the United States of America, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After
appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and 

  
 12 













 
obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or
appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and
upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority,
powers, rights, immunities, duties, and obligations. 
 8.2.2 Notice of Successor Warrant Agent. In the event a successor Warrant
Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the Transfer Agent for the shares of Common Stock not later than the effective date of any such appointment. 

8.2.3 Merger or Consolidation of Warrant Agent. Any entity into which the Warrant Agent may be merged or with which it may be
consolidated or any entity resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act. 

8.3 Fees and Expenses of Warrant Agent. 

8.3.1 Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent
hereunder and shall, pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder. 

8.3.2 Further Assurances. The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed, executed,
acknowledged, and delivered all such further and other acts, instruments, and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement. 

8.4 Liability of Warrant Agent. 

8.4.1 Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it
necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed
to be conclusively proved and established by a statement signed by the Co-Chief Executive Officer, Chief Financial Officer or Secretary of the Company and delivered to the Warrant Agent. The Warrant Agent may
rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement. 
 8.4.2
Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct, fraud or bad faith. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities,
including judgments, out-of-pocket costs and reasonable outside counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement,
except as a result of the Warrant Agent’s gross negligence, willful misconduct, fraud or bad faith. 
 8.4.3 Exclusions. The
Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or execution of any Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for any breach by
the Company of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent shall not be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the
manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or
reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant or as to whether any shares of Common Stock shall, when issued, be valid and fully paid and nonassessable. 

8.5 Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon
the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the
purchase of shares of Common Stock through the exercise of the Warrants. 

  
 13 













 8.6 Waiver. The Warrant Agent has no right of
set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust
Agreement, dated as of the date hereof, by and between the Company and Continental Stock Transfer & Trust Company as trustee thereunder) and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against
the Trust Account for any reason whatsoever. The Warrant Agent hereby waives any and all Claims against the Trust Account and any and all rights to seek access to the Trust Account.

 9.3 Applicable Law and Exclusive Forum. The validity, interpretation, and performance of this Agreement and
of the Warrants shall be governed in all respects by the laws of the State of New York. Subject to applicable law, the Company hereby agrees that any action, proceeding or claim against it arising out of or relating in any way to this 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, which jurisdiction shall be exclusive forum for any such

Any person or entity purchasing or otherwise acquiring any interest in the Warrants shall be deemed to have notice of and to have consented to

for the Southern District of New York (a “foreign action”) in the name of any warrant holder, such warrant holder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts
located within the State of New York or the United States District Court for the Southern District of New York in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”),
and (y) having service of process made upon such warrant holder in any such enforcement action by service upon such warrant holder’s counsel in the foreign action as agent for such warrant holder.

 9.4 Persons Having Rights under this Agreement. Nothing in this Agreement shall be
construed to confer upon, or give to, any person, corporation or other entity other than the parties hereto and the Registered Holders of the Warrants any right, remedy, or claim under or by reason of this Agreement or of any covenant, condition,
stipulation, promise, or agreement hereof. All covenants, conditions, stipulations, promises, and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their successors and assigns and of the
Registered Holders of the Warrants.

reasonable times at the office of the Warrant Agent in the United States of America, for inspection by the Registered Holder of any Warrant. The Warrant Agent may require any such holder to submit such holder’s Warrant for inspection by the
Warrant Agent. 
 9.6 Counterparts. This Agreement may be executed in any number of original or facsimile counterparts and each of
such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. 

9.7 Effect of Headings. The section headings herein are for convenience only and are not part of this Agreement and shall not affect the
interpretation thereof. 
 9.8 Amendments. This Agreement may be amended by the parties hereto without the consent of any Registered
Holder for the purpose of (i) curing any ambiguity or correcting any mistake, including conforming the provisions hereof to the description of the terms of the Warrants and this Agreement set forth in the Prospectus, or defective provision
contained herein or (ii) adding or changing any provisions with respect to matters or questions arising under this Agreement as the parties may deem necessary or desirable and that the parties deem to not adversely affect the rights of the

Warrants 
 THIS WARRANT

 THE EXPIRATION OF THE EXERCISE PERIOD PROVIDED FOR 

IN THE WARRANT AGREEMENT DESCRIBED BELOW 

Build Acquisition Corp. 

Incorporated Under the Laws of the State of Delaware 

CUSIP [•] 
 Warrant
Certificate 
 This Warrant Certificate certifies
that                , or registered assigns, is the registered holder of
                warrant(s) (the “Warrants” and each, a “Warrant”) to purchase shares of Class A common stock,
$0.0001 par value (“Common Stock”), of Build Acquisition 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 nonassessable 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 whole Warrant is initially exercisable for one fully paid and
non-assessable share of Common Stock. Fractional shares shall not 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 shall, 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 as set forth in the Warrant Agreement. 
 The initial Exercise Price per one
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 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 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                 , 2021 (the “Warrant Agreement”), duly executed and
delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (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 Exercise Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust
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 issuance of 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 principal corporate trust 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 governmental charge 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.

The undersigned hereby irrevocably elects to exercise the right, represented by this Warrant Certificate, to receive
                 shares of Common Stock and herewith tenders payment for such shares of Common Stock to the order of Build Acquisition Corp.

shares of Common Stock be registered in the name of                 , whose address is
                 and that such shares of Common Stock be delivered to                 
     whose address is                 . If said number of shares of Common Stock is less than all of the shares of Common Stock purchasable
hereunder, the undersigned requests that a new Warrant Certificate representing the remaining balance of such shares of Common Stock be registered in the name of
                , whose address is                and that such Warrant Certificate be delivered to
                , whose address is                 . 

In the event that the Warrant has been called for redemption by the Company pursuant to Section 6.2 of the Warrant Agreement
and a holder thereof elects to exercise its Warrant pursuant to a Make-Whole Exercise, the number of shares of Common Stock that this Warrant is exercisable for shall be determined in accordance with subsection
3.3.1(c) or Section 6.2 of the Warrant Agreement, as applicable. 
 In the event that the Warrant is a Private
Placement Warrant that is to be exercised on a “cashless” basis pursuant to subsection 3.3.1(c) of the Warrant Agreement, the number of shares of Common Stock that this Warrant is exercisable for shall be determined in
accordance with subsection 3.3.1(c) of the Warrant Agreement. 
 In the event that the Warrant is to be exercised on a
“cashless” basis pursuant to Section 7.4 of the Warrant Agreement, the number of shares of Common Stock that this Warrant is exercisable for shall be determined in accordance with Section 7.4 of the
Warrant Agreement. 
 In the event that the Warrant may be exercised, to the extent allowed by the Warrant Agreement, through cashless
exercise (i) the number of shares of Common Stock that this Warrant is exercisable for would be determined in accordance with the relevant section of the Warrant Agreement which allows for such cashless exercise and (ii) the holder hereof
shall complete the following: The undersigned hereby irrevocably elects to exercise the right, represented by this Warrant Certificate, through the cashless exercise provisions of the Warrant Agreement, to receive shares of Common Stock. If said
number of shares of Common Stock is less than all of the shares of Common Stock purchasable hereunder (after giving effect to the cashless exercise), the undersigned requests that a new Warrant Certificate representing the remaining balance of such
shares of Common Stock be registered in the name of                 , whose address is                and
that such Warrant Certificate be delivered to                 , whose address is
