Exhibit 4.1


 


WARRANT AGREEMENT


 


PIONEER MERGER CORP.


 


and


 


CONTINENTAL STOCK TRANSFER & TRUST COMPANY


 


Dated January 12, 2021


 


THIS WARRANT AGREEMENT (this “Agreement”),
dated January 12, 2021, is by and between Pioneer Merger Corp., a Cayman Islands exempted company (the “Company”),
and Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (in such capacity, the “Warrant
Agent”).


 


WHEREAS, it is proposed that the Company enter into that certain
Sponsor Warrants Purchase Agreement, with Pioneer Merger Sponsor LLC, a Cayman Islands limited liability company (the “Sponsor”),
pursuant to which the Sponsor will purchase an aggregate of 6,000,000 warrants (or up to 6,700,000 warrants if the underwriter
in the Public Offering (defined below) exercises its Over-allotment Option (as defined below) in full) simultaneously with the
closing of the Offering (and the closing of the Over-allotment Option, if applicable), bearing the legend set forth in Exhibit B
hereto (the “Private Placement Warrants”) at a purchase price of $1.50 per Private Placement Warrant.
Each Private Placement Warrant entitles the holder thereof to purchase one Ordinary Share (as defined below) at a price of $11.50
per share, subject to adjustment as described herein; and


 


WHEREAS, in order to finance the Company’s transaction
costs in connection with an intended initial merger, share exchange, asset acquisition, share purchase, reorganization or similar
business combination, involving the Company and one or more businesses (a “Business Combination”), the
Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors may, but are not obligated to,
loan the Company funds as the Company may require, of which up to $1,500,000 of such loans may be convertible into up to an additional
1,000,000 Private Placement Warrants at a price of $1.50 per Private Placement Warrant; and


 


WHEREAS, the Company is engaged in an initial public offering
(the “Offering”) of units of the Company’s equity securities, each such unit comprised of one Ordinary
Share and one-third of one Public Warrant (as defined below) (the “Units”) and, in connection therewith,
has determined to issue and deliver up to 11,666,667 redeemable warrants (including up to 1,750,000 redeemable warrants subject
to the Over-allotment Option) to public investors in the Offering (the “Public Warrants” and, together
with the Private Placement Warrants, the “Warrants”). Each whole Warrant entitles the holder thereof
to purchase one Class A ordinary share of the Company, par value $0.0001 per share (“Ordinary Shares”),
for $11.50 per share, subject to adjustment as described herein. Only whole Warrants are exercisable. A holder of the Public Warrants
will not be able to exercise any fraction of a Warrant; and


 


WHEREAS, the Company has filed
with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1,
File No. 333-251556 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 Ordinary Shares
included in the Units; and


 


WHEREAS, the Company desires the Warrant
Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration,
transfer, exchange, redemption and exercise of the Warrants; and


 


WHEREAS, the Company desires to provide for the form and provisions
of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and
immunities of the Company, the Warrant Agent and the holders of the Warrants; and


 




    


     


    

 


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


 


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


 


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


 


2. Warrants.


 


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


 


2.2. Effect of
Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant to this
Agreement, a certificated Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.


 


2.3. Registration.


 


2.3.1. Warrant
Register. The Warrant Agent shall maintain books (the “Warrant Register”), for the registration of
original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants in book- entry form,
the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and
otherwise in accordance with instructions delivered to the Warrant Agent by the Company. Ownership of beneficial interests in the
Public Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by institutions
that have accounts with The Depository Trust Company (the “Depositary”) (such institution, with respect
to a Warrant in its account, a “Participant”).


 


If the Depositary subsequently ceases to make its book-entry
settlement system available for the Public Warrants, the Company may instruct the Warrant Agent regarding making other arrangements
for book-entry settlement. In the event that the Public Warrants are not eligible for, or it is no longer necessary to have the
Public Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver
to the Warrant Agent for cancellation each book-entry Public Warrant, and the Company shall instruct the Warrant Agent to deliver
to the Depositary definitive certificates in physical form evidencing such Warrants (“Definitive Warrant Certificates”)
which shall be in the form annexed hereto as Exhibit A.


 


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


 


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


 


2.4. Detachability
of Warrants. The Ordinary Shares and Public Warrants comprising the Units shall begin separate trading on the 52nd day following
the date of the Prospectus or, if such 52nd day is not on a day, other than a Saturday, Sunday or federal holiday, on which banks
in New York City are generally open for normal business (a “Business Day”), then on the immediately succeeding
Business Day following such date, or earlier (the “Detachment Date”) with the consent of Citigroup Global
Markets Inc., but in no event shall the Ordinary Shares 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 underwriter of its right to purchase additional Units in the Offering (the “Over-allotment Option”),
if the Over-allotment Option is exercised prior to the filing of the Current
Report on Form 8-K, and (B) the Company issues a press release announcing when such separate trading shall begin.


 




    


     


    

 


2.5. Fractional
Warrants. The Company shall not issue fractional Warrants other than as part of the Units, each of which is comprised of one
Ordinary Share and one-third of one whole Public Warrant. If, upon the detachment of Public Warrants from the Units or otherwise,
a holder of Warrants would be entitled to receive a fractional Warrant, the Company shall round down to the nearest whole number
the number of Warrants to be issued to such holder.


 


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


 


(ii) including the Ordinary Shares issuable upon exercise
of the Private Placement Warrants, may not be transferred, assigned or sold until thirty (30) days after the completion by the
Company of an initial Business Combination, (iii) shall not be redeemable by the Company pursuant to Section 6.1
hereof and (iv) shall only be redeemable by the Company pursuant to Section 6.2 if the Reference Value (as defined
below) is less than $18.00 per share (subject to adjustment in compliance with Section 4 hereof); provided,
however, that in the case of (ii), the Private Placement Warrants and any Ordinary Shares issued upon exercise of the Private
Placement 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, any members or partners
of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates;


 


(b) in the case of
an individual, by gift to a member of one of the individual’s immediate family or to a trust, the beneficiary of which is
a member of the individual’s immediate family, an affiliate of such person or to a charitable organization;


 


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


 


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


 


(e) by private sales
or transfers made in connection with the consummation of the Company’s Business Combination at prices no greater than the
price at which the Private Placement Warrants or Ordinary Shares, as applicable, were originally purchased;


 


(f) by virtue of the Sponsor’s
organizational documents upon liquidation or dissolution of the Sponsor;


 


(g) to the Company
for no value for cancellation in connection with the consummation of our initial Business Combination;


 


(h) in the event of the
Company’s liquidation prior to the completion of its initial Business Combination; or


 


(i) in the event of
the Company’s completion of a liquidation, merger, share exchange or other similar transaction which results in all of the
public shareholders having the right to exchange their Ordinary Shares for cash, securities or other property subsequent to the
completion of the Company’s initial Business Combination;


 


provided, however, that,
in the case of clauses (a) through (f), these permitted transferees (the “Permitted Transferees”)
must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions in this Agreement.


 


3. Terms and Exercise
of Warrants.


 


3.1. Warrant Price.
Each whole Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Agreement,
to purchase from the Company the number of Ordinary Shares stated therein, at the price of $11.50 per share, subject to the adjustments
provided in Section 4 hereof and in the last sentence of this Section 3.1. The term “Warrant
Price” as used in this Agreement shall mean the price per share (including in cash or by payment of Warrants pursuant
to a “cashless exercise,” to the extent permitted hereunder) described in the prior sentence at which Ordinary Shares
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 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 days’ prior written notice of such reduction to Registered
Holders of the Warrants; and provided further, that any such reduction shall be identical among all of the Warrants.


 




    


     


    

 


3.2. Duration
of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”)
(A) commencing on the later of: (i) the date that is thirty (30) days after the first date on which the Company
completes a Business Combination, and (ii) the date that is twelve (12) months from the date of the closing of the
Offering, and (B) terminating at the earliest to occur of (x) 5:00 p.m., New York City time on the date that is
five (5) years after the date on which the Company completes its initial Business Combination, (y) the liquidation
of the Company in accordance with the Company’s amended and restated memorandum and articles of association, as amended
from time to time, if the Company fails to complete a Business Combination, and (z) other than with respect to the
Private Placement Warrants then held by the Sponsor or its 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 then held by the Sponsor or its Permitted Transferees in connection with a redemption pursuant to Section 6.1 hereof
or, if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof), Section 6.2
hereof) in the event of a redemption (as set forth in Section 6 hereof), each Warrant (other than a Private
Placement Warrant then held by the Sponsor or its Permitted Transferees in the event of a redemption pursuant to Section 6.1
hereof or, if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4
hereof), Section 6.2 hereof) not exercised on or before the Expiration Date shall become void, and all rights
thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m. New York City time on the
Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided
that the Company shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders of
the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants.


 


3.3. Exercise of Warrants.


 


3.3.1. Payment.
Subject to the provisions of the Warrant and this Agreement, a Warrant may be exercised by the Registered Holder thereof by delivering
to the Warrant Agent at its corporate trust department (i) the Definitive Warrant Certificate evidencing the Warrants to be
exercised, or, in the case of a Warrant represented by a book- entry, the Warrants to be exercised (the “Book-Entry
Warrants”) on the records of the Depositary to an account of the Warrant Agent at the Depositary designated for such
purposes in writing by the Warrant Agent to the Depositary from time to time, (ii) an election to purchase (“Election
to Purchase”) any Ordinary Shares pursuant to the exercise of a Warrant, properly completed and executed by the Registered
Holder on the reverse of the Definitive Warrant Certificate or, in the case of a Book-Entry Warrant, properly delivered by the
Participant in accordance with the Depositary’s procedures, and (iii) the payment in full of the Warrant Price for each
Ordinary Share 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 Ordinary Shares and the issuance of such Ordinary Shares, as follows:


 


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


 


(b) [Reserved];


 


(c) with respect to
any Private Placement Warrant, so long as such Private Placement Warrant is held by the Sponsor or a Permitted Transferee, by surrendering
the Warrants for that number of Ordinary Shares equal to (i) if in connection with a redemption of Private Placement Warrants
pursuant to Section 6.2 hereof, as provided in Section


 


6.2 hereof with respect to a Make-Whole Exercise and
(ii) in all other scenarios the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying
the Warrants, multiplied by the excess of the “Sponsor Fair Market Value” (as defined in this subsection
3.3.1(c)) less the Warrant Price by (y) the Sponsor Exercise Fair Market Value. Solely for purposes of this subsection
3.3.1(c), the “Sponsor Fair Market Value” shall mean the average last reported sale price of the
Ordinary Shares for the ten (10) trading days ending on the third (3rd) trading day prior
to the date on which notice of exercise of the Private Placement Warrant is sent to the Warrant Agent;


 


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


 




    


     


    

 


(e) as provided in Section 7.4
hereof.


 


3.3.2. Issuance
of Ordinary Shares 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 Ordinary Shares to which he, she
or it is entitled, registered in such name or names as may be directed by him, her or it on the register of members of the Company,
and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for
the number of shares as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not
be obligated to deliver any Ordinary Shares 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 Ordinary Shares 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 Ordinary Shares upon exercise of a Warrant unless the Ordinary Shares issuable upon such Warrant exercise
have been registered, qualified or deemed to be exempt from registration or qualification under the securities laws of the state
of residence of the Registered Holder of the Warrants. Subject to Section 4.6 of this Agreement, a Registered Holder
of Warrants may exercise its Warrants only for a whole number of Ordinary Shares. 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 an Ordinary Share, the Company shall round down to the nearest whole number, the number of Ordinary Shares
to be issued to such holder.


 


3.3.3. Valid Issuance.
All Ordinary Shares issued upon the proper exercise of a Warrant in conformity with this Agreement and the amended and restated
memorandum and articles of association of the Company shall be validly issued, fully paid and nonassessable.


 


3.3.4. Date of
Issuance. Each person in whose name any book-entry position or certificate, as applicable, for Ordinary Shares is issued and
who is registered in the register of members of the Company shall for all purposes be deemed to have become the holder of record
of such Ordinary Shares 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 register of members 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 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 Ordinary Shares outstanding
immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of Ordinary Shares
beneficially owned by such person and its affiliates shall include the number of Ordinary Shares issuable upon exercise of the
Warrant with respect to which the determination of such sentence is being made, but shall exclude Ordinary Shares 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
shares 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 Ordinary Shares, the holder may rely on the number of outstanding Ordinary Shares as reflected
in (1) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report
on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent public announcement by the
Company or (3) any other notice by the Company or Continental Stock Transfer & Trust Company, as transfer agent (in
such capacity, the “Transfer Agent”), setting forth the number of Ordinary Shares 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 Ordinary Shares then outstanding. In any case, the number of issued
and outstanding Ordinary Shares shall be determined after giving effect to the conversion or exercise of equity securities of the
Company by the holder and its affiliates since the date as of which such number of issued and outstanding Ordinary Shares 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. Share Capitalizations.


 


4.1.1. Sub-Divisions.
If after the date hereof, and subject to the provisions of Section 4.6 below, the number of issued and
outstanding Ordinary Shares is increased by a capitalization or share dividend of Ordinary Shares to all or substantially all
holders of Ordinary Shares, or by a sub-division of Ordinary Shares or other similar event, then, on the effective date of
such share capitalization, sub- division or similar event, the number of Ordinary Shares issuable on exercise of each Warrant
shall be increased in proportion to such increase in the issued and outstanding Ordinary Shares. A rights offering made to
all or substantially all holders of Ordinary Shares entitling holders to purchase Ordinary Shares at a price less than the
 “Historical Fair Market Value” (as defined below) shall be deemed a capitalization of a number of Ordinary Shares
equal to the product of (i) the number of Ordinary Shares 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 Ordinary Shares)
multiplied by (ii) one (1) minus the quotient of (x) the price per Ordinary Share paid in such rights offering
divided by (y) the Historical Fair Market Value. For purposes of this subsection 4.1.1, (i) if the rights
offering is for securities convertible into or exercisable for Ordinary Shares, in determining the price payable for Ordinary
Shares, there shall be taken into account any consideration received for such rights, as well as any additional amount
payable upon exercise or conversion and (ii) “Historical Fair Market Value” means the volume
weighted average price of the Ordinary Shares during the ten (10) trading day period ending on the trading day prior to
the first date on which the Ordinary Shares trade on the applicable exchange or in the applicable market, regular way,
without the right to receive such rights. No Ordinary Shares shall be issued at less than their par value.


 


4.1.2. Extraordinary
Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, pays to all or substantially all
of the holders of the Ordinary Shares a dividend or make a distribution in cash, securities or other assets on account of
such Ordinary Shares (or other shares into which the Warrants are convertible), other than (a) as described in subsection
4.1.1 above, (b) Ordinary Cash Dividends (as defined below), (c) to satisfy the redemption rights of the
holders of the Ordinary Shares in connection with a proposed initial Business Combination, (d) to satisfy the redemption
rights of the holders of the Ordinary Shares in connection with a shareholder vote to amend the Company’s amended and
restated memorandum and articles of association (i) to modify the substance or timing of the Company’s obligation
to provide holders of Ordinary Shares the right to have their shares redeemed in connection with the Company’s initial
Business Combination or to redeem 100% of the Company’s public shares if it does not complete its initial Business
Combination within the time period required by the Company’s Amended and Restated Memorandum and Articles of
Association, as amended from time to time, or (ii) with respect to any other provision relating to the rights of holders
of Ordinary Shares, (e) as a result of the repurchase of Ordinary Shares by the Company if a proposed initial Business
Combination is presented to the shareholders of the Company for approval or (f) in connection with the redemption of
public shares upon the failure of the Company to complete its initial Business Combination and any subsequent distribution of
its assets upon its liquidation (any such non- excluded event being referred to herein as an “Extraordinary
Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such
Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined by the Company’s board of
directors (the “Board”), in good faith) of any securities or other assets paid on each Ordinary
Share 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 Ordinary Shares during the 365-day period ending
on the date of declaration of such dividend or distribution to the extent it does not exceed $0.50 (which amount shall be
adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and
excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of
Ordinary Shares issuable on exercise of each Warrant).


 




    


     


    

 


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


 


4.3. Adjustments
in Exercise Price. Whenever the number of Ordinary Shares 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 Ordinary
Shares purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which
shall be the number of Ordinary Shares so purchasable immediately thereafter.


 


4.4. Raising of
the Capital in Connection with the Initial Business Combination. If (x) the Company issues additional Ordinary Shares
or equity-linked securities for capital raising purposes in connection with the closing of its initial Business Combination at
an issue price or effective issue price of less than $9.20 per Ordinary Share (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 Class B ordinary shares, par value $0.0001 per share, of the Company held by the Sponsor or such affiliates,
as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds
from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the
Company’s initial Business Combination on the date of the completion of the Company’s initial Business Combination
(net of redemptions), and (z) the volume-weighted average trading price of Ordinary Shares during the twenty (20) trading
day period starting on the trading day prior to the day on which the Company consummates its initial Business Combination (such
price, the “Market Value”) is below $9.20 per share, the Warrant Price shall be adjusted (to the nearest
cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, the $18.00 per share redemption trigger
price described in Section 6.1 and Section 6.2 shall be adjusted (to the nearest cent) to be equal to 180%
of the higher of the Market Value and the Newly Issued Price and the $10.00 per share redemption trigger price described in Section 6.2
shall be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price.





 




    


     


    

 


4.5. Replacement
of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the issued and outstanding
Ordinary Shares (other than a change under Section 4.1 or Section 4.2 hereof or that solely affects the
par value of such Ordinary Shares), or in the case of any merger or consolidation of the Company with or into another corporation
(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 issued and outstanding Ordinary Shares), or in the case of any sale or conveyance to another corporation
or entity of the assets or other property of the Company as an entirety or substantially as an entirety in connection with which
the Company is dissolved, the holders of the Warrants shall thereafter have the right to purchase and receive, upon the basis and
upon the terms and conditions specified in the Warrants and in lieu of the Ordinary Shares of the Company immediately theretofore
purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares or 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 Ordinary Shares 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 Ordinary Shares 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 Ordinary Shares (other than a tender, exchange or redemption offer made by the Company in connection with
redemption rights held by shareholders of the Company as provided for in the Company’s amended and restated memorandum and
articles of association or as a result of the repurchase of Ordinary Shares by the Company if a proposed initial Business Combination
is presented to the shareholders of the Company for approval) under circumstances in which, upon completion of such tender or exchange
offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange
Act) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2
under the Exchange Act) and any members of any such group of which any such affiliate or associate is a part, own beneficially
(within the meaning of Rule 13d-3 under the Exchange Act) more than 50% of the issued and
outstanding Ordinary Shares, 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 shareholder 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 Ordinary Shares 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 Ordinary Shares in the applicable event is payable in the form of shares in the successor
entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market,
or is to be so listed for trading or quoted immediately following such event, and if the Registered Holder properly exercises
the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable event by the
Company pursuant to a Current Report on Form 8-K filed with the Commission, the Warrant Price shall be reduced by an
amount (in dollars) equal to the difference of (i) the Warrant Price in effect prior to such reduction minus (ii)
(A) the Per Share Consideration (as defined below) (but in no event less than zero) minus (B) the Black-Scholes
Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant
immediately prior to the consummation of the applicable event based on the Black-Scholes Warrant Model for a Capped American
Call on Bloomberg Financial Markets (assuming zero dividends) (“Bloomberg”). For purposes of
calculating such amount, (i) Section 6 of this Agreement shall be taken into account, (ii) the price of
each Ordinary Share shall be the volume weighted average price of the Ordinary Shares during the ten (10) trading day
period ending on the trading day prior to the effective date of the applicable event, (iii) the assumed volatility shall
be the 90 day volatility obtained from the HVT function on Bloomberg determined as of the trading day immediately prior to
the day of the announcement of the applicable event and (iv) the assumed risk-free interest rate shall correspond to the
U.S. Treasury rate for a period equal to the remaining term of the Warrant. “Per Share
Consideration” means (i) if the consideration paid to holders of the Ordinary Shares consists exclusively
of cash, the amount of such cash per Ordinary Share, and (ii) in all other cases, the volume weighted average price of
the Ordinary Shares 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 Ordinary Shares covered by subsection
4.1.1, then such adjustment shall be made pursuant to subsection 4.1.1 or Sections 4.2, 4.3 and this Section 4.4.
The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations,
mergers or consolidations, sales or other transfers. In no event shall the Warrant Price be reduced to less than the par
value per share issuable upon exercise of such Warrant.


 


4.6. Notices of
Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares issuable upon exercise of a Warrant,
the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such
adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant,
setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence
of any event specified in Sections 4.1, 4.2, 4.3, 4.4 or 4.5, the Company shall give written
notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder in the Warrant
Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not
affect the legality or validity of such event.


 


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


 


4.8. Form of
Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants
issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrants initially
issued pursuant to this Agreement; provided, however, that the Company may at any time in its sole discretion make
any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any
Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be
in the form as so changed.





 




    


     


    

 


5. Transfer and Exchange
of Warrants.


 


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


 


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


 


5.3. Fractional
Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall result in
the issuance of a warrant certificate or book-entry position for a fraction of a warrant, except as part of the Units.


 


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


 


5.5. Warrant Execution
and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of
this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever
required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.


 


5.6. Transfer of
Warrants. Prior to the Detachment Date, the Public Warrants may be transferred or exchanged only together with the Unit in
which such Warrant is included, and only for the purpose of effecting, or in conjunction with, a transfer or exchange of such Unit.
Furthermore, each transfer of a Unit on the register relating to such Units shall operate also to transfer the Warrants included
in such Unit. Notwithstanding the foregoing, the provisions of this Section 5.6 shall have no effect on any transfer
of Warrants on and after the Detachment Date.


 


6. Redemption.


 


6.1. Redemption
of Warrants for Cash. Subject to Section 6.5 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 a Redemption Price of $0.01 per Warrant, provided
that (a) the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4
hereof) and (b) there is an effective registration statement covering the issuance of the Ordinary Shares 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 Ordinary Shares. 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 a Redemption Price of $0.10 per Warrant,
provided that (i) the Reference Value equals or exceeds $10.00 per share (subject to adjustment in compliance with
Section 4 hereof) and (ii) if 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 Ordinary Shares 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 Ordinary Shares 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 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 Ordinary Shares to be issued for each Warrant exercised
in a Make- Whole Exercise shall be determined by a straight-line interpolation between the number of shares set forth for the higher
and lower Redemption Fair Market Values and the earlier and later redemption dates, as applicable, based on a 365- or 366-day year,
as applicable.


 


The share prices set forth in the column headings of the table
above shall be adjusted as of any date on which the number of shares issuable upon exercise of a Warrant or the Exercise Price
is adjusted pursuant to Section 4 hereof. If the number of shares issuable upon exercise of a Warrant is adjusted pursuant
to Section 4 hereof, the adjusted share prices in the column headings shall equal the share prices immediately prior to such
adjustment, multiplied by a fraction, the numerator of which is the number of shares deliverable upon exercise of a Warrant immediately
prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a Warrant as so adjusted.
The number of shares in the table above shall be adjusted in the same manner and at the same time as the number of shares issuable
upon exercise of a Warrant. If the Exercise Price of a warrant is adjusted, (a) in the case of an adjustment pursuant to Section 4.4
hereof, the adjusted share prices in the column headings shall equal the share prices immediately prior to such adjustment multiplied
by a fraction, the numerator of which is the higher of the Market Value and the Newly Issued Price and the denominator of which
is $10.00 and (b) in the case of an adjustment pursuant to Section 4.1.2 hereof, the adjusted share prices in the column
headings shall equal the share prices immediately prior to such adjustment less the decrease in the Exercise Price pursuant to
such Exercise Price adjustment. In no event shall the number of shares issued in connection with a Make-Whole Exercise exceed 0.361
Ordinary Shares per Warrant (subject to adjustment)


 


6.3. Date Fixed
for, and Notice of, Redemption; Redemption Price; Reference Value. In the event that the Company elects to redeem the Warrants
pursuant to Sections 6.1 or 6.2, the Company shall fix a date for the redemption (the “Redemption Date”).
Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than thirty (30) days prior
to the Redemption Date (the “30-day Redemption Period”) to the Registered Holders of the Warrants to
be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in the manner herein provided
shall be conclusively presumed to have been duly given whether or not the Registered Holder received such notice. As used in this
Agreement, (a) “Redemption Price” shall mean the price per Warrant at which any Warrants are redeemed pursuant to Sections
6.1 or 6.2 and (b) “Reference Value” shall mean the last reported sales price of the
Ordinary Shares 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
of this Agreement) 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. The Company agrees that (a) the redemption rights provided in Section 6.1 hereof
shall not apply to the Private Placement Warrants if at the time of the redemption such Private Placement Warrants continue to
be held by the Sponsor or its Permitted Transferees and (b) if the Reference Value equals or exceeds $18.00 per share (subject
to adjustment in compliance with Section 4 hereof), the redemption rights provided in Section 6.2 hereof
shall not apply to the Private Placement Warrants if at the time of the redemption such Private Placement Warrants continue to
be held by the Sponsor or its Permitted Transferees. However, once such Private Placement Warrants are transferred (other than
to Permitted Transferees in accordance with Section 2.6 hereof), the Company may redeem the Private Placement Warrants
pursuant to Section 6.1 or 6.2 hereof, provided that the criteria for redemption are met, including the opportunity
of the holder of such Private Placement Warrants to exercise the Private Placement Warrants prior to redemption pursuant to Section 6.4
hereof. Private Placement Warrants that are transferred to persons other than Permitted Transferees shall upon such transfer cease
to be Private Placement Warrants and shall become Public Warrants under this Agreement, including for purposes of Section 9.8
hereof.


 


7. Other Provisions
Relating to Rights of Holders of Warrants.


 


7.1. No Rights
as Shareholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a shareholder 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 shareholders in respect of the meetings of shareholders 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 Ordinary Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued Ordinary
Shares that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.


 






    


     


    

 


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


 


7.4.1. Registration
of the Ordinary Shares. The Company agrees that as soon as practicable, but in no event later than twenty (20) Business Days
after the closing of its initial Business Combination, it shall use its commercially reasonable efforts to file with the Commission
a registration statement for the registration, under the Securities Act, of the Ordinary Shares issuable upon exercise of the Warrants.
The Company shall use its commercially reasonable efforts to cause the same to become effective within sixty (60) Business Days
following the closing of its initial Business Combination and to maintain the effectiveness of such registration statement, and
a current prospectus relating thereto, until the expiration or redemption of the Warrants in accordance with the provisions of
this Agreement. If any such registration statement has not been declared effective by the sixtieth (60th)
Business Day following the closing of the Business Combination, holders of the Warrants shall have the right, during the period
beginning on the sixty-first (61st) Business Day after the closing of the Business
Combination and ending upon such registration statement being declared effective by the Commission, and during any other period
when the Company shall fail to have maintained an effective registration statement covering the issuance of the Ordinary Shares
issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless basis,” by exchanging the Warrants
(in accordance with Section 3(a)(9) of the Securities Act or another exemption) for that number of Ordinary Shares equal
to the lesser of (A) the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Warrants, multiplied by the excess of the
 “Fair Market Value” (as defined below) less the Warrant Price by (y) the Fair Market Value and
(B) 0.361. Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean
the volume-weighted average price of the Ordinary Shares as reported during the ten (10) trading day period ending on
the trading day prior to the date that notice of exercise is received by the Warrant Agent from the holder of such Warrants
or its securities broker or intermediary. The date that notice of “cashless exercise” is received by the Warrant
Agent shall be conclusively determined by the Warrant Agent. In connection with the “cashless exercise” of a
Public Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company (which
shall be an outside law firm with securities law experience) stating that (i) the exercise of the Warrants on a
 “cashless basis” in accordance with this subsection 7.4.1 is not required to be registered under the
Securities Act and (ii) the Ordinary Shares issued upon such exercise shall be freely tradable under United States
federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Securities Act)
of the Company and, accordingly, shall not be required to bear a restrictive legend. Except as provided in subsection
7.4.2, for the avoidance of doubt, unless and until all of the Warrants have been exercised or have expired, the Company
shall continue to be obligated to comply with its registration obligations under the first three sentences of this subsection
7.4.1.


 


7.4.2. Cashless
Exercise at Company’s Option. If the Ordinary Shares are at the time of any exercise of a Public Warrant not listed on
a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of
the Securities Act, the Company may, at its option, (i) require holders of Public Warrants who exercise Public Warrants to
exercise such Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities
Act as described in subsection 7.4.1 and (ii) in the event the Company so elects, the Company shall (x) not be
required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Ordinary
Shares issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary, and (y) use its
commercially reasonable efforts to register or qualify for sale the Ordinary Shares issuable upon exercise of the Public Warrant
under applicable blue sky laws to the extent an exemption is not available.


 


8. Concerning the Warrant
Agent and Other Matters.


 


8.1. Payment of
Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant
Agent in respect of the issuance or delivery of Ordinary Shares upon the exercise of the Warrants, but the Company shall not be
obligated to pay any transfer taxes in respect of the Warrants or such shares.


 


8.2. Resignation, Consolidation,
or Merger of Warrant Agent.


 


8.2.1. Appointment
of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged
from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the
office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing
a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of
thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder
of a Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the holder of any
Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant
Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation
or other entity organized and existing under the laws of the State of New York, in good standing and having its principal office
in the United States of America, and authorized under such laws to exercise corporate trust powers and subject to supervision or
examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with all the authority,
powers, rights, immunities, duties, and 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 Ordinary Shares not later than the effective date of any such appointment.


 


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


 


8.3. Fees and Expenses
of Warrant Agent.


 


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


 


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


 


8.4. Liability of Warrant
Agent.


 


8.4.1. Reliance
on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary
or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder,
such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively
proved and established by a statement signed by the Chief Executive Officer, the President, the Chief Financial Officer, Chief
Operating Officer, the General Counsel, the Secretary or the 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, fraud or bad faith. The Company
agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, out-of-pocket
costs and reasonable outside counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement,
except as a result of the Warrant Agent’s gross negligence, willful misconduct, fraud or bad faith.


 


8.4.3. Exclusions.
The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or
execution of any Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for any breach by the
Company of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent shall not be responsible
to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or
amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it
by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Ordinary Shares
to be issued pursuant to this Agreement or any Warrant or as to whether any Ordinary Shares shall, when issued, be valid and fully
paid and nonassessable.


 


8.5. Acceptance
of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the
terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised
and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the purchase of Ordinary Shares
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 Continental Stock Transfer & Trust Company as trustee thereunder) and
hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason
whatsoever. The Warrant Agent hereby waives any and all Claims against the Trust Account and any and all rights to seek access
to the Trust Account.

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.

9.3. Applicable
Law. The validity, interpretation, and performance of this Agreement and of the Warrants shall be governed in all respects
by the laws of the State of New York. Subject to applicable law, the Company hereby agrees that any action, proceeding or claim
against it arising out of or relating in any way to this Agreement shall be brought and enforced in the courts of the State of
New York or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction,
which jurisdiction shall be exclusive forum for any such action, proceeding or claim. 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 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, corporation
or other entity other than the parties hereto and the Registered Holders of the Warrants any right, remedy, or claim under or by
reason of this Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. All covenants, conditions, stipulations,
promises, and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their
successors and assigns and of the Registered Holders of the Warrants.


 




    


     


    

 


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 United States of America, for inspection by the Registered Holder of any Warrant. The Warrant Agent may require any
such holder to submit such holder’s Warrant for inspection by the Warrant Agent.


 


9.6. Counterparts.
This Agreement may be executed in any number of original or facsimile counterparts and each of such counterparts shall for all
purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.


 


9.7. Effect of
Headings. The section headings herein are for convenience only and are not part of this Agreement and shall not affect the
interpretation thereof.


 


9.8. Amendments.
This Agreement may be amended by the parties hereto without the consent of any Registered Holder for the purpose of (i) curing
any ambiguity or 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 defective provision contained herein, (ii) amending the definition of “Ordinary
Cash Dividend” as contemplated by and in accordance with the second sentence of subsection 4.1.2 or (iii) 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. All other
modifications or amendments, including any modification or amendment to increase the Warrant Price or shorten the Exercise Period
and any amendment to the terms of only the Private Placement Warrants, 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 any provision of this Agreement with respect to the Private Placement Warrants, 50% of the then-outstanding Private
Placement 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 this Agreement a provision
as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

Warrant Certificate


 


This Warrant Certificate certifies that                           ,
or registered assigns, is the registered holder of warrant(s) (the “Warrants” and each, a “Warrant”)
to purchase Class A ordinary shares, $0.0001 par value (“Ordinary Shares”), of Pioneer Merger Corp.,
a Cayman Islands exempted company (the “Company”). Each


 


Warrant entitles the holder, upon exercise during the period
set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and nonassessable Ordinary
Shares 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 Ordinary Share. Fractional shares shall not be issued upon exercise of any Warrant. If, upon the exercise of
Warrants, a holder would be entitled to receive a fractional interest in an Ordinary Share, the Company shall, upon exercise, round
down to the nearest whole number the number of Ordinary Shares to be issued to the Warrant holder. The number of Ordinary Shares
issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events as set forth in the Warrant
Agreement.


 


The initial Exercise Price per one Ordinary Share for any Warrant
is equal to $11.50 per share. The Exercise Price is subject to adjustment upon the occurrence of certain events as set forth in
the Warrant Agreement.


 


Subject to the conditions set forth in the Warrant Agreement,
the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period,
such Warrants shall become void. The Warrants may be redeemed, subject to certain conditions, as set forth in the Warrant Agreement.


 


Reference is hereby made to the further provisions of this Warrant
Certificate set forth on the reverse hereof and such further provisions shall for all purposes have the same effect as though fully
set forth at this place.


 


This Warrant Certificate shall not be valid
unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement. This Warrant Certificate shall be governed
by and construed in accordance with the internal laws of the State of New York.

[Form of Warrant Certificate]


 


[Reverse]


 


The Warrants evidenced by this Warrant Certificate are part
of a duly authorized issue of Warrants entitling the holder on exercise to receive                  Ordinary Shares
and are issued or to be issued pursuant to a Warrant Agreement dated as of January 12, 2021 (the “Warrant Agreement”),
duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant
agent (the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made
a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties
and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder”
meaning the Registered Holders or Registered Holder, respectively) of the Warrants. A copy of the Warrant Agreement may be obtained
by the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein
shall have the meanings given to them in the Warrant Agreement.


 


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


 


Notwithstanding anything else in this Warrant Certificate or
the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering the
issuance of the Ordinary Shares to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder
relating to the Ordinary Shares 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 Ordinary Shares 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 an Ordinary Share, the Company shall, upon exercise, round down to the nearest whole number of Ordinary Shares 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 shareholder of the Company.


 






    


     


    

 


Election to Purchase


 


(To Be Executed Upon Exercise of Warrant)


 


The undersigned hereby irrevocably elects to exercise the
right, represented by this Warrant Certificate, to receive Ordinary Shares and herewith tenders payment for such Ordinary
Shares to the order of Pioneer Merger Corp. (the “Company”) in the amount of
$                   in
accordance with the terms hereof. The undersigned requests that a certificate for such Ordinary Shares be registered in the
name of                  , whose
address
is                        and
that such Ordinary Shares be delivered
to                        whose
address
is                        .
If said                           number of Ordinary Shares is less than all of the Ordinary Shares purchasable hereunder, the undersigned requests
that a new Warrant Certificate representing the remaining balance of such Ordinary Shares be registered in the name
of                     , whose address
is                     and that such Warrant Certificate be delivered
to                    , whose address
is                        .


 


In the event that the Warrant has been called for redemption
by the Company pursuant to Section 6.2 of the Warrant Agreement and a holder thereof elects to exercise its Warrant
pursuant to a Make-Whole Exercise, the number of Ordinary Shares that this Warrant is exercisable for shall be determined in accordance
with subsection 3.3.1(c) or Section 6.2 of the Warrant Agreement, as applicable.


 


In the event that the Warrant is a Private Placement Warrant
that is to be exercised on a “cashless” basis pursuant to subsection 3.3.1(c) of the Warrant Agreement,
the number of Ordinary Shares that this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(c) of
the Warrant Agreement.


 


In the event that the Warrant is to be exercised on a “cashless”
basis pursuant to Section 7.4 of the Warrant Agreement, the number of Ordinary Shares that this Warrant is exercisable
for shall be determined in accordance with Section 7.4 of the Warrant Agreement.


 


In the event that the Warrant may be exercised, to the extent
allowed by the Warrant Agreement, through cashless exercise (i) the number of Ordinary Shares that this Warrant is exercisable
for would be determined in accordance with the relevant section of the Warrant Agreement which allows for such cashless exercise
and (ii) the holder hereof shall complete the following: The undersigned hereby irrevocably elects to exercise the right,
represented by this Warrant Certificate, through the cashless exercise provisions of the Warrant Agreement, to receive Ordinary
Shares. If said number of shares is less than all of the Ordinary Shares purchasable hereunder (after giving effect to the cashless
exercise), the undersigned requests that a new Warrant Certificate representing the remaining balance of such Ordinary Shares be
registered in the name of                            , whose address is                        and that such Warrant
Certificate be delivered to                        , whose address is                        .
