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”), Sponsor or any of its affiliates, or certain of the Company’s
executive officers or directors may loan to 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 150,000 units of the Company’s equity securities (the
“Working Capital Units” and, together with the Public Units and the Private Units, the “Units”), each such Working Capital Unit comprised of one share of Common Stock
and one-third of one warrant to purchase one share of Common Stock at an initial exercise price of $11.50 per share of Common Stock (the “Working Capital Warrants” and,
together with the Public Warrants and the Private Warrants, the “Warrants”), at a price of $10.00 per Working Capital Unit; 












 WHEREAS, each whole Warrant entitles the holder thereof to purchase one share of Common
Stock for $11.50 per share, subject to adjustment as described herein; 
 WHEREAS, the Company has filed with the Securities and Exchange
Commission (the “Commission”) a registration statement on Form S-1, File No. 333-255234 (the “Registration
Statement”), and prospectus (the “Prospectus”) for the registration, under the Securities Act of 1933, as amended (the “Securities Act”), of the Offering; 

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, 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. 

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 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 Warrants shall be shown on, and the transfer of such ownership shall be effected through,
records maintained by institutions that have accounts with the Depositary (such institution, with respect to a Warrant in its account, a “Participant”). 

If The Depository Trust Company (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 which shall be in the form annexed hereto as Exhibit A. Notwithstanding anything herein to the contrary, any Warrant, or portion thereof,
may be issued as part of, and be represented by, a 












 
Unit. Any Warrant so issued shall have the same terms, force and effect as a certificated Warrant that has been duly countersigned by the Warrant Agent in accordance with the terms of this
Agreement. Certificates representing the Warrants, if issued, shall be signed by, or bear the facsimile signature of, the Chairman of the Board, President, Chief Executive Officer, Chief Financial Officer, Secretary or other executive 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 Common Stock and 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 Oppenheimer and William Blair as representatives of the Underwriters, but in no event shall the Common
Stock and the 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 received by the Company from the exercise by the Underwriters of their right to purchase additional Public 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 No
Fractional Warrants Other Than as Part of Units. 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 Warrant. If, upon the detachment of 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 the number of Warrants to be issued to such holder. 
 2.6 Private Warrants and Working Capital
Warrants. The Private Warrants and the Working Capital Warrants shall be identical to the Public Warrants, except that so long as they are held by the Sponsor, an Underwriter or any of their respective Permitted Transferees (as defined below),
the Private Warrants and the Working Capital Warrants: (i) may be exercised for cash or on a cashless basis, pursuant to subsection 3.3.1(c) hereof, (ii) shall be subject to
the Lock-up (as defined below), and (iii) shall not be redeemable by the Company; provided, however, that in the case of (ii), the Private Warrants, the
Working Capital Warrants and any shares of Common Stock held by the Sponsor, the Underwriters or their Permitted Transferees and issued upon exercise of the Private Warrants and the Working Capital Warrants may be transferred by the holders thereof:

 (a) amongst the Sponsor and its affiliates, to the Company’s executive officers or directors, or to any affiliate or family member
of any of the Company’s executive officers or directors; 
 (b) in the case of an entity, as a distribution to its partners,
stockholders or members upon its liquidation; 
 (c) in the case of an individual, (i) by bona fide gift to such person’s
immediate family or to a trust, the beneficiary of which is a member of such person’s immediate family, an affiliate of such person or to a charitable organization, (ii) by virtue of the laws of descent and distribution upon death of such
person, (iii) pursuant to a qualified domestic relations order; 
 (d) by certain pledges to secure obligations incurred in connection
with purchases of the Company’s securities; 
 (e) through 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 Private Warrants were originally purchased; 












 (f) in the case of an Underwriter, to such Underwriter’s affiliates or any entity
controlled by such Underwriter; or 
 (g) to the Company for no value for cancellation in connection with the consummation of the Business
Combination; 
 provided, however, that, in each case (except clause (g)), these transferees (the
“Permitted Transferees”) shall enter into a written agreement with the Company agreeing to be bound by the transfer restrictions agreed to by the original holder in connection with the purchase of the securities being
transferred. 
 For the purposes of this Agreement, the term “Lock-up” means
the restrictions on transfer set forth in Section 7 of the Unit Purchase Agreements. 
 2.7 Exercise Period for
Underwriters. Notwithstanding anything herein to the contrary, any Private Warrants held by the Underwriters or their respective designees or affiliates shall not be exercisable on the date immediately following the fifth anniversary of the
effective date of the Registration Statement. 
 3. Terms and Exercise of Warrants. 

3.1 Exercise Price. Each whole Warrant shall, when countersigned by the Warrant Agent, 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 “Exercise Price” as used in this Agreement shall mean the price per
share 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 Exercise Price at any time prior to the Expiration Date (as defined below) for a period of not less than
twenty (20) Business Days, 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”) commencing on the later of: (i) the date that is thirty (30) days after the first date on which the Company completes its initial Business Combination, or (ii) the date that is twelve
(12) months from the date of the closing of the Offering, and terminating at 5:00 p.m., New York City time on the earlier to occur of: (x) 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’s trust account in accordance with the Company’s amended and restated certificate of incorporation, as amended from time to time, if the Company fails to consummate an initial
Business Combination, or (z) other than with respect to the Private Warrants and the Working Capital Warrants to the extent then held by the original purchasers thereof or their Permitted Transferees, the Redemption Date (as defined below) as
provided in Section 6.2 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. Except with respect to the right to receive the Redemption Price (as defined below) (other than with
respect to a Private Warrant or a Working Capital Warrant to the extent then held by the original purchasers thereof or their Permitted Transferees) in the event of a redemption (as set forth
in Section 6 hereof), each Warrant (other than a Private Warrant or a Working Capital Warrant in the event of a redemption to the extent then held by the original purchasers thereof or their Permitted
Transferees) 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, when countersigned by the Warrant
Agent, may be exercised by the Registered Holder thereof by surrendering it, at the office of the Warrant Agent, or at the office of its successor as Warrant Agent, in the Borough of Manhattan, City and State of New York, with the subscription form,
as set forth in the Warrant, duly executed, and by paying in full the Exercise 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 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; 
 (b) in the event of a redemption pursuant
to Section 6 hereof in which the Company’s board of directors (the “Board”) has elected to require all holders of the Warrants to exercise such Warrants on a “cashless
basis,” 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 difference between
the Exercise Price and the Fair Market Value, as defined in this subsection 3.3.1(b) by (y) the Fair Market Value. Solely for purposes of this subsection
3.3.1(b) and Section 6.3, the “Fair Market Value” shall mean the average reported last sale price of the Common Stock for the five (5) trading days ending on the third
trading day prior to the date on which the notice of redemption is sent to the holders of the Warrants, pursuant to Section 6 hereof; 

(c) with respect to any Private Warrant or Working Capital Warrant, so long as such Private Warrant or Working Capital Warrant is held by the
Sponsor, the Underwriters or their respective Permitted Transferees, by surrendering such Private Warrants or Working Capital 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 difference between the Exercise Price and the Fair Market Value, as defined in this subsection 3.3.1(c), by (y) the Fair Market Value. Solely for
purposes of this subsection 3.3.1(c), the “Fair Market Value” shall mean the average reported last sale price of the Common Stock for the five (5) 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 
 (d) 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 Exercise 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. Notwithstanding the foregoing, the Company
shall not be obligated to deliver any shares of Common Stock pursuant to the exercise of a Public Warrant and shall have no obligation to settle such Public 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. No Public
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 Public 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 Public Warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a
Public Warrant, the holder of such Warrant shall not be entitled to exercise such Public Warrant and such Public Warrant may have no value and expire worthless, in which case the purchaser of a Public Unit containing such Public Warrant shall have
paid the full purchase price for the Public Unit solely for the share of Common Stock underlying such Public Unit. In no event will the Company be required to net cash settle the Public Warrant exercise. The Company may require holders of Public
Warrants to settle the Public 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 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 Exercise 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% (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 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. 

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 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) (an
“Extraordinary Dividend”), then the Exercise 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; provided, however, that none of the following shall be deemed an Extraordinary Dividend for purposes of this
provision: (a) any adjustment described in subsection 4.1.1 above, (b) 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 does not exceed $0.50 (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 Exercise Price or to the number of shares of Common Stock issuable on exercise of each Warrant) but only with respect to the amount of the aggregate cash dividend or cash distribution equal to or less than $0.50, (c) any payment to
satisfy the redemption rights of the holders of the shares of Common Stock in connection with a proposed initial Business Combination or (d) any payment in connection with the Company’s liquidation and the distribution of its assets upon
its failure to consummate a Business Combination. Solely for purposes of illustration, if the Company, at a time while the Warrants are outstanding and unexpired, pays a cash dividend of $0.35 and previously paid an aggregate of $0.40 of cash
dividends and cash distributions on the Common Stock during the 365-day period ending on the date of declaration of such $0.35 dividend, then the Warrant Price will be decreased, effectively
immediately after the effective date of such $0.35 dividend, by $0.25 (the absolute value of the difference between $0.75 (the aggregate amount of all cash dividends and cash distributions paid or made in
such 365-day period, including such $0.35 dividend) and $0.50 (the greater of (x) $0.50 and (y) the aggregate amount of all cash dividends and cash distributions paid or made in such 365-day period prior to such $0.35 dividend)). 
 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 Exercise 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 Exercise Price shall be adjusted (to the nearest cent) by multiplying such Exercise 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 (a) the Company issues additional shares of Common Stock or
equity-linked securities 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 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 Founders or their affiliates, without taking into account any founder shares held by them prior to such issuance), (b) the aggregate gross proceeds from
such issuances represent more than 65% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and
(c) the volume weighted average trading price of Common Stock during the 20 trading-day period starting on the trading day prior to the day on which the Company consummates the initial Business
Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the greater of (i) the Market Value or (ii) the
price at which the Company issues the additional shares of Common Stock or equity-linked securities. 
 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 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 entity or conversion of the Company into 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; and if any reclassification also













 
results in a change in shares of Common Stock covered by Sections 4.1 or 4.2, then such adjustment shall be made pursuant to Sections 4.1, 4.2 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 Exercise 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 Exercise 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 Exercise 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 Exercise 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 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 the initial 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, in the case of certificated Warrants, 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 in the event that a Warrant surrendered for transfer bears a restrictive legend (as in the case of the Private 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 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. Subject to Section 6.4 hereof, not less than all of the
outstanding Warrants may be redeemed, at the option of the Company, at any time while they are 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 6.2 below, at the price of $0.01 per Warrant (the “Redemption Price”), provided that the last sales price of the Common Stock reported has been at least $18.00 per share
(subject to adjustment in compliance with Section 4 hereof), on each of twenty (20) trading days within the thirty (30) trading-day period ending
on the third Business Day prior to the date on which notice of the redemption is given and provided that there is an effective registration statement covering 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 6.2 below) or the Company has elected to require the
exercise of the Warrants on a “cashless basis” pursuant to subsection 3.3.1; provided, however, that if and when the Public Warrants become redeemable by the Company, the Company may not exercise such redemption right if
the issuance of shares of Common Stock upon exercise of the Public Warrants is not exempt from registration or qualification under applicable state blue sky laws or the Company is unable to effect such registration or qualification. 

6.2 Date Fixed for, and Notice of, Redemption. In the event that the Company elects to redeem all of the Warrants, 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 (such 30-day 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. 

6.3 Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in
accordance with subsection 3.3.1(b) of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2 hereof and prior to the
Redemption Date. In the event that the Company determines to require all holders of Warrants to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1, the notice of redemption shall contain the
information necessary to calculate the number of shares of Common Stock to be received upon exercise of the Warrants, including the Fair Market Value (as such term is defined in subsection 3.3.1(b) hereof) in such case. 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. 

6.4 Exclusion of Private Warrants and Working Capital Warrants. The Company agrees that the redemption rights provided in
this Section 6 shall not apply to the Private Warrants or the Working Capital Warrants if at the time of the redemption such Private Warrants or Working Capital Warrants continue to be held by the Sponsor,
the Underwriters or their respective Permitted Transferees. However, once such Private Warrants or Working Capital Warrants are transferred (other than to Permitted Transferees under Section 2.6), the Company
may redeem the Private Warrants and the Working Capital Warrants, provided that the criteria for redemption are met, including the opportunity of the holder of such Private Warrants or Working Capital Warrants to exercise the Private Warrants and
the Working Capital Warrants prior to redemption pursuant to Section 6.3. Private Warrants and Working Capital Warrants that are transferred to persons other than Permitted Transferees shall upon such transfer
cease to be Private Warrants and shall become Public Warrants under this Agreement. 












 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 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 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 best efforts to cause the same to become effective 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 90th day following the closing of the Business Combination, holders of the Warrants shall have the right, during
the period beginning on the 91st 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 quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the
difference between the Exercise Price and the Fair Market Value (as defined below) by (y) the Fair Market Value. Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the volume
weighted average price of the Common Stock as reported during the five (5) 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, 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 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 rule), 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 (or any successor rule) as
described in subsection 7.4.1 and (ii) 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 Common Stock issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary. If
the Company does not elect at the time of exercise to require a holder of Public Warrants who exercises Public Warrants to exercise such Public Warrants on a “cashless basis,” it agrees to use its best efforts to register or qualify for
sale the Common Stock issuable upon exercise of the Public Warrant under the blue sky laws of the state of residence in those states in which the Public Warrants were initially offered by the Company of the exercising Public Warrant holder 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 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 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 President, Chief Executive Officer or Chairman 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. 
 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, costs and
reasonable 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 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. Miscellaneous Provisions. 

9.1 Successors. All the covenants and provisions of this Agreement by or for the benefit of the Company or the Warrant
Agent shall bind and inure to the benefit of their respective successors and assigns. 
 9.2 Notices. Any notice,
statement or demand authorized by this Agreement to be given or made by the Warrant Agent or by the holder of any Warrant to or on the Company shall be sufficiently given when so delivered if by hand or overnight delivery or if sent by certified

 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, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The
Company hereby agrees that any action, proceeding or claim against it arising out of or relating in any way to this Agreement, including under the Securities Act, 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 the exclusive forum for any such action, proceeding or claim. Subject to applicable law, the Company hereby waives
any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. 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 of 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 his Warrant for inspection by it. 
 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 curing any ambiguity, or curing, correcting or supplementing any defective provision contained herein or adding or changing any other 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 interest of the Registered Holders. All other modifications or amendments, including any amendment to increase the Exercise Price
or shorten the Exercise Period and any amendment to the terms of only the Private Warrants or Working Capital Warrants, shall require the vote or written consent of the Registered Holders of 50% of the then outstanding Public Warrants. Any amendment
solely to the Private Warrants or the Working Capital Warrants shall also require the vote or written consent of a majority of the holders of the then-outstanding Private Warrants or the Working Capital Warrants, as applicable. Notwithstanding the
foregoing, the Company may lower the Exercise 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 this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable. 












 IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of
the date first above written.

WARRANT AGREEMENT DESCRIBED BELOW

CUSIP 37518W 114 
 Warrant
Certificate 
 This Warrant Certificate certifies
that                , or its registered assigns, is the registered holder of
                 warrant(s) evidenced hereby (the “Warrants” and each, a “Warrant”)
to purchase shares of Common Stock, $0.0001 par value (“Common Stock”), of GigInternational1, Inc., a Delaware corporation (the “Company”). Each whole Warrant
entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and non-assessable shares of
Common Stock as set forth below, at the exercise price (the “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. No fractional shares will be issued upon exercise of any Warrant. If, upon the exercise of Warrants, a holder would be entitled to receive a
fractional interest in a share of Common Stock, the Company will, upon exercise, round down to the nearest whole number 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 set forth in the Warrant Agreement. 
 The initial
Exercise Price per 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 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. 
 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, without regard to conflicts of laws principles thereof.

 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) 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 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.
