 Exhibit 4.4 

WARRANT AGREEMENT 
 THIS
WARRANT AGREEMENT (this “Agreement”), dated as of         , 2020, is by and between Thayer Ventures Acquisition Corporation, a Delaware corporation (the
“Company”), and Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (in such capacity, the “Warrant Agent”, and also referred to herein as the
“Transfer Agent”). 
 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 Class A common stock of the Company, par value $0.0001 per share (“Common Stock”), and
one-half of one redeemable Public Warrant (as defined below) (the “Units”) and, in connection therewith, has determined to issue and deliver up to 7,500,000 warrants (or up to 8,625,000 warrants to the extent the
Over-allotment Option (as defined below) is exercised) to public investors in the Offering (the “Public Warrants”); 

WHEREAS, the Company has entered into that certain Private Placement Warrants Purchase Agreement with Thayer Ventures Acquisition Holdings
LLC, a Delaware limited liability company (the “Sponsor”), pursuant to which the Sponsor agreed to purchase an aggregate of 8,000,000 warrants (or up to 8,900,000 warrants to the extent the Over-allotment Option is exercised)
simultaneously with the closing of the Offering (and the closing of the Over-allotment Option, if applicable) hereto (the “Private Placement Warrants”) at a purchase price of $1.00 per Private Placement Warrant; 

WHEREAS, in order to finance the Company’s transaction costs in connection with an intended initial Business Combination (as defined
below), the Sponsor or an affiliate of the Sponsor or the Company’s officers and directors may, but are not obligated to, loan to the Company funds as the Company may require, of which up to $1,500,000 of such loans may be converted into up to
an additional 1,500,000 warrants at a price of $1.00 per warrant (the “Working Capital Warrants,” and, together with the Private Placement Warrants and the Public Warrants, the “Warrants”); 

WHEREAS, the Company has filed with the U.S. Securities and Exchange Commission (the “Commission”) a registration
statement on Form S-1, File No. 333-249390 (the “Registration Statement”), and 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; 
 WHEREAS, each
whole Warrant entitles the holder thereof to purchase one share of Common Stock for $11.50 per whole 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; 
 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; 
 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. 

  
 1 














 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. 

2.1 Form of Warrant. Each Warrant shall be initially issued in registered form only, and, if a physical certificate is
issued, shall be in substantially the form of Exhibit A hereto, the provisions of which are incorporated herein and shall be signed by, or bear the facsimile signature of, the Chairperson of the Board of Directors
(“Board”), Co-President, 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. All of the Public Warrants shall
initially be represented by one or more book-entry certificates (each, a “Book-Entry Warrant Certificate”). 

2.2 Effect of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant
to this Agreement, a Warrant certificate 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. All of the Public Warrants shall initially be represented by one or more Book-Entry Warrant Certificates deposited with The Depository
Trust Company (the “Depositary”) and registered in the name of Cede & Co., a nominee of the Depositary. 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 (i) the Depositary or its nominee for each Book-Entry Warrant Certificate, or (ii) institutions that have accounts with the Depositary (each 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 Warrant Certificate, and the Company shall instruct the Warrant Agent to deliver to the
Depositary definitive certificates in physical form evidencing such Warrants (“Definitive Warrant Certificate”). Such Definitive Warrant Certificate shall be in the form annexed hereto as Exhibit A, with
appropriate insertions, modifications and omissions, as provided above. 
 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 (notwithstanding any notation of ownership or other writing on a Definitive Warrant Certificate made by anyone other than the Company or the Warrant Agent), 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 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 

  
 2 














 
normal business (a “Business Day”), then on the immediately succeeding Business Day following such date, or earlier (the “Detachment Date”) with
the consent of Stifel, Nicolaus & Company, Incorporated and Oppenheimer & Co. Inc., as the representatives of the several underwriters, but in no event shall the 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
Form 8-K, and (B) the Company issues a press release and files with the Commission a Current Report on Form 8-K 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 share of Common Stock and one-third of one whole Public Warrant. If, upon the detachment of Public Warrants from 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 of Warrants to be issued to such holder. 
 2.6 Private Placement Warrants and Working Capital
Warrants. The Private Placement Warrants and the Working Capital 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), as applicable, the
Private Placement Warrants and the Working Capital Warrants: (i) may be exercised for cash or on a cashless basis, pursuant to subsection 3.3.1(b) hereof, (ii) including the shares of Common Stock issuable upon exercise of the
Private Placement Warrants and the Working Capital Warrants, may not be transferred, assigned or sold until the date that is thirty (30) days after the completion by the Company of an initial Business Combination (as defined below), and
(iii) shall not be redeemable by the Company (except as provided in Section 6.2); provided, however, that in the case of (ii), the Private Placement Warrants and the Working Capital Warrants and any shares of Common
Stock held by the Sponsor or its Permitted Transferees, as applicable, and issued upon exercise of the Private Placement Warrants and the Working Capital Warrants may be transferred by the holders thereof: 

(a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, to
the Sponsor, any members or partners of the Sponsor or their affiliates, or any affiliates of the Sponsor, or any employees of such affiliates; 

(b) in the case of an individual, by gift to a member of such individual’s immediate family or to a trust, the beneficiary of which
is a member of such individual’s immediate family, an affiliate of such individual or to a charitable organization; 
 (c) in the
case of an individual, by virtue of laws of descent and distribution upon death of such person; 
 (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 initial Business Combination at prices no greater than the price at which the Warrants or shares of Common Stock were originally purchased; 

(f) by virtue of the laws of the State of Delaware or the limited liability company agreement of the Sponsor upon dissolution of the
Sponsor; 
 (g) to the Company for no value for cancellation in connection with the consummation of its initial Business Combination;

 (h) in the event of the Company’s liquidation prior to the consummation of a Business Combination; or 

  
 3 














 (i) in the event that, subsequent to the consummation of the Company’s initial
Business Combination, the Company completes a liquidation, merger, capital stock exchange or other similar transaction which results in all of the Company’s public stockholders having the right to exchange their shares of Common Stock for cash,
securities or other property; provided, however, that, in the case of clauses (a) through (f), any such transferees (the “Permitted Transferees”) enter into a written agreement with the Company agreeing to
be bound by the transfer restrictions in this Agreement and the other restrictions contained in the letter agreement, dated as of the date hereof, by and among the Company, the Sponsor and the Company’s officers and directors. 

2.7 Working Capital Warrants. Each of the Working Capital Warrants shall be identical to the Private Placement Warrants. 

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 the 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 fifteen (15) 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 five
(5) Business 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”)
commencing on the later of: (i) the date that is thirty (30) days after the first date on which the Company completes a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination,
involving the Company and one or more businesses (a “Business Combination”), and (ii) the date that is twelve (12) months from the date of the closing of the Offering, and terminating at the earlier to occur of:
(a) 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, (b) 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, (c) other than with respect to the Private Placement Warrants or the Working Capital Warrants to the extent then held
by the Sponsor or its 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 6.3 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 or a Working Capital 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 outstanding Warrant (other than a Private Placement Warrant or a Working Capital Warrant to the extent 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. 

  
 4 














 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 Book-Entry Warrant Certificate, 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”) 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 Certificate, properly delivered by the Participant in accordance with the Depositary’s procedures, and (iii) payment in full of the Warrant Price for each full 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 good bank draft payable to the order of the Warrant Agent or by wire
transfer of immediately available funds; 
 (b) with respect to any Private Placement Warrant or Working Capital Warrant, so long as
such Private Placement Warrant or Working Capital Warrant is held by the Sponsor or its Permitted Transferees, by surrendering the Warrants for that number of shares of Common Stock equal to 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 “Historical Fair Market Value”, as defined in this subsection 3.3.1(b), over the Warrant Price by (y) the Historical Fair Market
Value. Solely for purposes of this subsection 3.3.1(b), the “Historical Fair Market Value” shall mean the average last reported sale price of the Common Stock for the ten (10) trading days ending on the third trading day prior
to the date on which notice of exercise of the Warrant is sent to the Warrant Agent; or 
 (c) as provided in Section 6.2
or 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 full 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, and if such Warrant shall not have been exercised in full, a new book-entry position
or countersigned Warrant, as applicable, for the number of shares of Common Stock as to which such Warrant shall not have been exercised. If fewer than all the Warrants evidenced by a Book-Entry Warrant Certificate are exercised, a notation shall be
made to the records maintained by the Depositary, its nominee for each Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance of the Warrants remaining after such exercise. 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 Common Stock issuable upon such Warrant exercise has 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. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Warrant, the
holder of such Warrant shall not be entitled to exercise such Warrant and such Warrant may have no value and expire worthless, in which case the purchaser of a Unit containing such Public Warrants shall have paid the full purchase price for the Unit
solely for the shares of Common Stock underlying such Unit. In no event will the Company be required to net cash settle the exercise of a Warrant. 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. A Registered Holder of Warrants may exercise its Warrants only for a whole number of shares of Common Stock.


  
 5 














 3.3.3 Valid Issuance. All shares of Common Stock issued upon the proper
exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and non-assessable. 
 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 4.9% or 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 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 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 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
outstanding shares of Common Stock is increased by a stock dividend payable in 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 outstanding shares of Common Stock. A rights offering to holders of the Common Stock entitling holders to purchase
shares of Common Stock at a price less than the “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 

  
 6 














 
Common Stock) and (ii) one (1) minus the quotient of (x) the price per share of Common Stock paid in such rights offering divided by (y) the Fair Market Value. For purposes of
this subsection 4.1.1, (i) if the rights offering is for securities convertible into or exercisable for Common Stock, in determining the price payable for 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) “Fair Market Value” means the volume weighted average price of the Common Stock as reported 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 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,
shall pay a dividend or make a distribution in cash, securities or other assets to all or substantially all of the holders of the Common Stock on account of such shares of Common Stock (or other shares of the Company’s capital stock into which
the Warrants are convertible), other than (a) as described in subsection 4.1.1 above, (b) Ordinary Cash Dividends (as defined below), (c) to satisfy the redemption rights of the holders of the 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 amended and restated certificate of incorporation (as amended from time
to time, the “Charter”) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the shares of Common Stock included in
the Units sold in the Offering if the Company does not complete the initial Business Combination within the time period set forth in the Charter or with respect to any other provisions relating to stockholders’ rights or pre-initial Business
Combination activity, or (e) in connection with the redemption of the shares of Common Stock included in the Units sold in the Offering upon the failure of the Company to complete its initial Business Combination and any subsequent distribution
of its assets upon its liquidation (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such
Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined by the Board, in good faith) of any securities or other assets paid on each share of Common Stock in respect of such Extraordinary Dividend. For purposes of
this subsection 4.1.2, “Ordinary Cash Dividends” means any cash dividend or cash distribution which, when combined on a per share basis, with the per share amounts of all other cash dividends and cash distributions
paid on the Common Stock during the 365-day period ending on the date of declaration of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and
excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of shares of Common Stock issuable on exercise of each Warrant) does not exceed $0.50 (being 5% of the offer price of the Units in
the Offering). 
 4.2 Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.6
hereof, the number of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split or 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 outstanding shares of Common Stock. 

4.3 Adjustments in Warrant Price. 

4.3.1 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. 

4.3.2 If (x) the Company issues additional shares of Common Stock or securities convertible into or exercisable or exchangeable for
shares of Common Stock for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per share (as adjusted for stock splits, stock dividends, rights
issuances, subdivisions, reorganizations, recapitalizations and the like) 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 (as defined below) held by the Sponsor or such affiliates, as applicable, prior to such 

  
 7 














 
issuance (the “Newly Issued Price”)), (y) the aggregate gross proceeds from such issuances represent more than 50% of the total equity proceeds (net of redemptions),
and interest thereon, available for funding the initial Business Combination, and (z) the volume weighted average trading price of the Common Stock during the 10 trading day period starting on the trading day after the day on which the Company
consummates the Business Combination (such price, the “Market Value”) is below $9.20 per share (as adjusted for stock splits, stock dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like),
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, and the $18.00 per share redemption trigger price described under Section 6.1 and Section 6.2 will
be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price and the $10.00 per share redemption trigger price described under Section 6.2 will be adjusted (to the nearest cent) to be equal
to the higher of the Market Value and the Newly Issued Price. 
 4.4 Replacement of Securities upon Reorganization, etc. In
case of any reclassification or reorganization of the outstanding shares of Common Stock (other than a change under subsections 4.1.1 or 4.1.2 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 entity or conversion of the Company as another entity (other than a consolidation or merger in which the Company is the continuing corporation and that
does not result in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another 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 of stock or other 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 the 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 consolidation or merger, 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 consolidation or merger 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 the 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 Charter or as a result of the redemption 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 (or any successor rule)) 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 (or any successor rule)) 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 (or any successor rule)) more than 50% of the
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 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 provided for in this Section 4; provided further that if less than 70% of the consideration
receivable by the holders of the 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 (but in no event less than zero) of (i) the Warrant Price in effect prior
to such reduction minus (ii) (A) the Per Share Consideration (as defined below) 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 (“Bloomberg”). 

  
 8 














 For purposes of calculating such amount, (1) Section 6 of this Agreement shall be taken
into account, (2) the price of each share of Common Stock shall be the volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the effective date of the
applicable event, (3) 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 (4) 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 the 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 as reported 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 will the Warrant Price be reduced to less than the par value per share issuable upon exercise of the Warrant. 

4.5 Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares of Common Stock 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 of Common Stock
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 or 4.4, 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. 
 4.6 No
Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional shares of Common Stock 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. 
 4.7 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 of Common Stock 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. 

4.8 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 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 4.8 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. 
 4.9 No Adjustment. For the avoidance of doubt, no
adjustment shall be made to the terms of the Warrants solely as a result of an adjustment to the conversion ratio of the Company’s Class B common stock (the “Class B Common Stock”) into shares of Common Stock
or the conversion of the shares of Class B Common Stock into shares of Common Stock, in each case, pursuant to the Charter.

 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, in the case of a certificated Warrant, 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 in any Book-Entry Warrant Certificate or Definitive Warrant Certificate, each Book-Entry Warrant Certificate and Definitive Warrant
Certificate may be transferred only in whole and only to the Depositary, to another nominee of the Depositary, to a successor depositary, or to a nominee of a successor depositary; 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 and the Working Capital 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 6.5 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 6.3 below, at the Redemption Price of
$0.01 per Warrant, provided that (a) the Reference Value (as defined below) 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 6.3 below). 

6.2 Redemption of Warrants for Shares of Common Stock. Not less than all of the outstanding Warrants may be redeemed, at the
option of the Company, commencing ninety (90) days after they are first exercisable and prior to their expiration, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in
Section 6.3 below, at a Redemption Price of $0.10 per Warrant, provided 

  
 10 














 
that (i) the Reference Value equals or exceeds $10.00 per share (subject to adjustment in compliance with Section 4 hereof) and (ii) if 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 shares of Common Stock
for 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 (as defined below) 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 will 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. 
 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. If the number of shares issuable upon exercise of a Warrant is adjusted pursuant to Section 4, the
adjusted stock prices in the column headings will equal the stock prices immediately prior to such adjustment, multiplied by a 

  
 11 














 
fraction, the numerator of which is the Exercise Price of the Warrant after such adjustment and the denominator of which is the price of the warrant immediately prior to such adjustment. In such
an event, the number of shares in the table above shall be adjusted by multiplying such share amounts 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. If the Exercise Price of a Warrant is adjusted, 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. In no event shall
the number of shares issued in connection with a Make-Whole Exercise exceed 0.361 shares of Common Stock per Warrant (subject to adjustment). 

6.3 Date Fixed for, and Notice of, Redemption. In the event that the Company elects to redeem all of the Warrants pursuant to
Section 6.1 or Section 6.2, the Company shall fix a date for the redemption (the Redemption Date”). In the event that the Company elects to redeem all of the Warrants pursuant to Section 6.2,
the Company shall fix a date for the redemption (the “30-day 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 (such period, the “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 Section 6.1 or Section 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 trading day prior to the date on which notice of the redemption is given. 

6.4 Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance
with Section 6.2 hereof) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.3 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. 
 6.5 Exclusion of
Private Placement Warrants and Working Capital Warrants. The Company agrees that the redemption rights provided in Section 6.1 shall not apply to the Private Placement Warrants or the Working Capital Warrants if at the time of the
redemption such Private Placement Warrants or Working Capital Warrants continue to be held by the Sponsor or its Permitted Transferees, as applicable. However, once such Private Placement Warrants or Working Capital Warrants are transferred (other
than to Permitted Transferees under Section 2.6), the Company may redeem the Private Placement Warrants and the Working Capital Warrants pursuant to Section 6.1 hereof, provided that the criteria for redemption are met,
including the opportunity of the holder of such Private Placement Warrants or Working Capital Warrants to exercise the Private Placement Warrants and the Working Capital Warrants prior to redemption pursuant to Section 6.1. Private
Placement Warrants and Working Capital Warrants that are transferred to persons other than Permitted Transferees shall upon such transfer cease to be Private Placement Warrants or Working Capital Warrants and shall become Public Warrants under this
Agreement. The restrictions set forth under this Section 6.5 shall not apply to redemptions pursuant to Section 6.2 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. 

  
 12 














 7.3 Reservation 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 Common Stock; Cashless Exercise at Company’s Option. 

7.4.1 Registration of the 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 best efforts to file with the Commission and have an effective registration statement registering, under the Securities Act, the issuance of the shares
of Common Stock issuable upon exercise of the Warrants. The Company shall use its best efforts to cause the same to become effective within sixty (60) Business Days after the closing of the Company’s initial Business Combination and to
maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared
effective by the 60th Business Day following the closing of the Business Combination, holders of the Warrants shall have the right, during the period beginning on the 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 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 any successor rule) or another exemption) for that number of shares of Common
Stock equal to the lesser of (A) 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) over the
Warrant Price by (y) the Fair Market Value and (B) 0.361 per whole Warrant. Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the average reported last sale price of the Common Stock for 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 (or any successor rule)) 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 any 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 is at the time of any exercise of a Warrant not
listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act (or any successor statute), the Company may, at its option, 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 (or any successor statute) as described in subsection 7.4.1 and
(i) in the event the Company so elects, the Company shall 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 or (ii) if the Company does not so elect, the Company agrees to use its best efforts to register or qualify for sale the shares of Common Stock issuable upon exercise of the
Public Warrants under the blue sky laws to the extent an exemption is not available. Notwithstanding anything herein to the contrary, but without limiting the rights of the Holder to receive shares of Common Stock issuable upon exercise of the
Warrants on a “cashless exercise,” in the event there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the shares of Common Stock issuable upon exercise of the
Warrants to the Holder, under no circumstance will the Company be required to net cash settle the Warrants.

 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 of Common Stock. 

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 organized and existing under the laws of the State
of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, 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 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 Common Stock not later than the effective date of any such appointment. 

8.2.3 Merger or Consolidation of Warrant Agent. Any corporation into which the Warrant Agent may be merged or with which it may
be consolidated or any corporation 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, Co-President, Secretary or Chairperson of the Board 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. 

  
 14 














 8.4.2 Indemnity. The Warrant Agent shall be liable hereunder only for its own
gross negligence, willful misconduct 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 non-assessable. 
 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. 

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 the Warrant Agent 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. Notwithstanding the foregoing, the
provisions of this paragraph will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal district courts of the United States of America are the sole and exclusive forum. 

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
the forum provisions in this Section 9.3. If any action, the subject matter of which is within the scope the forum provisions above, is filed in a court other than a court located within the State of New York or the United States District Court
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 or corporation 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. 

9.5 Examination of the Warrant Agreement. A copy of this Agreement shall be available at all reasonable times at the office of the
Warrant Agent in the Borough of Manhattan, City and State of New York, 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 (i) for the purpose of curing any ambiguity or to correct any mistake, including to conform the provisions hereof to the description of the terms of the Warrants and this Agreement set forth in the Prospectus, or curing,
correcting or supplementing any defective provision contained herein, or 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
shall not adversely affect the rights of the Registered Holders under this Agreement, or (ii) to provide for the delivery of Alternative Issuance pursuant to Section 4.4. All other modifications or amendments, including any modification or
amendment to increase the Warrant Price or shorten the Exercise Period shall require the vote or written consent of the Registered Holders of 50% of the then-outstanding Public Warrants and, solely with respect to any amendment to the terms of the
Private Placement Warrants or Working Capital Warrants or any provision of this Agreement with respect to the Private Placement Warrants or Working Capital Warrants, 50% of the number of then outstanding Private Placement Warrants and Working
Capital Warrants. Notwithstanding the foregoing, the Company may lower the Warrant Price or extend the duration of the Exercise Period pursuant to Sections 3.1 and 3.2, respectively, without the consent of the Registered Holders. 

9.9 Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof
shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of
