4.Eligibility.

Unless otherwise determined by the Committee in a manner that is consistent with Section 423 of the Code, any individual who is an Eligible Employee as of the first day of an Offering Period shall be eligible to participate in such Offering Period, subject to the requirements of Section 423 of the Code.
b.Limits on Participation. Notwithstanding any provision of the Plan to the contrary, no Eligible Employee shall be granted an option under the Plan if:
a.immediately after the grant of the option, such Eligible Employee (or any other person whose stock would be attributed to such Eligible Employee pursuant to Section 424(d) of the Code) would own capital stock of the Company and/or hold outstanding options to purchase stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or any Subsidiary, or
b.such option would permit his or her rights to purchase stock under all employee stock purchase plans (described in Section 423 of the Code) of the Company and its Subsidiaries to accrue at a rate that exceeds $15,000 (or such other amount as the Committee may determine in its discretion, which amount may in no event exceed $25,000) of the Fair Market Value of such stock (determined at the time the option is granted) for each calendar year in which such option is outstanding at any time.
5.Offering Periods. The Plan shall be implemented by a series of Offering Periods, each of which shall be six (6) months in duration, with new Offering Periods commencing on or about January 1st and July 1st of each year (or such other times as determined by the Committee). The Committee shall have the authority to change the duration, frequency, start and end dates of Offering Periods.
6.Participation.
a.Enrollment; Payroll Deductions. An Eligible Employee may elect to participate in the Plan by properly completing an Enrollment Form and submitting it to the Company, in accordance with the
-3-

enrollment procedures and deadlines established by the Committee. Such Enrollment Form may be an electronic document completed by the Eligible Employee or generated by the Eligible Employee via participation in an interactive voice response system. Participation in the Plan is entirely voluntary. By submitting an Enrollment Form, the Eligible Employee authorizes payroll deductions from his or her pay check in an amount equal to at least two percent (2%), but not more than ten percent (10%) (only in whole percentages) of his or her Compensation on each pay day occurring during an Offering Period (or such other maximum percentage as the Committee may establish from time to time in its discretion before an Offering Period begins). A Participant may not make any additional contributions to his or her plan notional account. Payroll deductions shall commence on the first payroll date following the Offering Date and end on the last payroll date on or before the Purchase Date. The Company shall maintain records of all payroll deductions but shall have no obligation to pay interest on payroll deductions or to hold such amounts in a trust or in any segregated account.
a.Election Changes. During an Offering Period, a Participant may elect to decrease or increase his or her rate of payroll deductions applicable to such Offering Period only once. To make such a change, the Participant must submit a new Enrollment Form authorizing the new rate of payroll deductions, which Enrollment Form must be submitted at least thirty (30) days prior to the Purchase Date. Any such election to increase or decrease payroll deductions will be effective as soon as reasonably practicable after the Company’s receipt of the new Enrollment Form. A Participant may decrease or increase his or her rate of payroll deductions for any future Offering Period by submitting a new Enrollment Form authorizing the new rate of payroll deductions during the enrollment period established pursuant to Section 6.1 for that Offering Period.
b.Automatic Re-enrollment. The deduction rate selected in the Enrollment Form shall remain in effect for subsequent Offering Periods unless the Participant (a) submits a new Enrollment Form authorizing a new level of payroll deductions in accordance with Section 6.2, (b) withdraws from the Plan in accordance with Section 10, or (c) terminates employment or otherwise ceases to be an Eligible Employee in accordance with Section 11.
c.Automatic Decrease. Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 4 above, a Participant’s payroll deductions will be decreased to zero percent (0%). Payroll deductions will recommence at the rate provided in such Participant’s Enrollment Form when permitted under Section 423(b)(8) of the Code and Section 4 unless the Participant sooner withdraws from the Plan in accordance with Section 10 or terminates employment or otherwise ceases to be an Eligible Employee in accordance with Section 11.
7.Grant of Option. On each Offering Date, each Participant in the applicable Offering Period shall be granted an option to purchase, on the Purchase Date, a number of shares of Common Stock determined by dividing the Participant's accumulated payroll deductions by the applicable Purchase Price, subject to the terms and conditions of this Plan.
8.Exercise of Option/Purchase of Shares. A Participant's option to purchase shares of Common Stock will be exercised automatically on the Purchase Date of each Offering Period, subject to the terms and conditions of this Plan. The Participant's accumulated payroll deductions will be used to purchase the maximum number of whole shares that can be purchased with the amounts in the Participant's notional account. No fractional shares may be purchased under the Plan unless otherwise provided by the Committee. Any cash in lieu of fractional shares remaining after the purchase of whole shares upon exercise of the option will be credited to a Participant’s notional account and carried forward and applied toward the purchase of whole shares for the next following Offering Period, subject to earlier withdrawal by the Participant in accordance with Section 10 or termination of employment or cessation as an Eligible Employee in accordance with Section 11. Shares issued pursuant to the Plan may be evidenced in such manner as the Committee may determine and may be issued in certificated form or issued pursuant to book-entry procedures.
9.Transfer of Shares. The Company will arrange for the delivery to each Participant of the shares of Common Stock purchased upon exercise of his or her option as soon as reasonably practicable. The Committee may permit or require that the shares be deposited directly into an ESPP Share Account established in the name of the Participant with a Designated Broker and may require that the shares of Common Stock be retained with such Designated Broker for a specified period of time. Participants will not have any voting, dividend or other rights of a shareholder with respect to the shares of Common
-4-

Stock subject to any option granted hereunder until such shares have been delivered pursuant to this Section 9.
10.Withdrawal.
a.Withdrawal Procedure. A Participant may withdraw from an Offering by submitting a revised Enrollment Form indicating his or her election to withdraw more than thirty (30) days prior to the Purchase Date. All (but not less than all) of the accumulated payroll deductions held on behalf of a Participant in his or her notional account (that have not been used to purchase shares of Common Stock) shall be paid to the Participant as soon as administratively practicable following receipt of the Participant's Enrollment Form indicating his or her election to withdraw, and the Participant's option shall be automatically terminated. If a Participant submits a revised Enrollment Form indicating his or her election to withdraw within the thirty (30) day period prior to the Purchase Date, the accumulated payroll deductions shall be used to purchase shares on such Purchase Date, the Participant's participation in the Plan shall thereafter be automatically terminated, and any payroll deductions remaining in the Participant's notional account shall be returned to the Participant as soon as administratively practicable following such Purchase Date. If a Participant withdraws from an Offering Period, no payroll deductions will be made during any succeeding Offering Period, unless the Participant re-enrolls in accordance with Section 6.1 of the Plan.
b.Effect on Succeeding Offering Periods. A Participant's election to withdraw from an Offering Period will not have any effect upon his or her eligibility to participate in succeeding Offering Periods that commence following the completion of the Offering Period from which the Participant withdraws subject to eligibility and compliance with Section 6.1 and other requirements set forth in this Plan and established by the Committee.
11.Termination of Employment; Change in Employment Status. Upon termination of a Participant's employment for any reason, or a change in the Participant's employment status following which the Participant is no longer an Eligible Employee, which in either case occurs more than thirty (30) days prior to the Purchase Date, the Participant will be deemed to have withdrawn from the Plan, the Participant’s option shall be automatically terminated, and the payroll deductions in the Participant's notional account (that have not been used to purchase shares of Common Stock) shall be returned to the Participant, or in the case of the Participant's death, to any person(s) entitled to such amounts under Section 17, as soon as administratively practicable following such termination or change in status. If the Participant's termination of employment or change in status occurs within the thirty (30) days prior to a Purchase Date, the accumulated payroll deductions shall be used to purchase shares on such Purchase Date, the Participant's participation in the Plan shall thereafter be automatically terminated, and any payroll deductions remaining in the Participant's notional account shall be returned to the Participant, or in the case of the Participant's death, to any person(s) entitled to such amounts under Section 17, as soon as administratively practicable following such Purchase Date.
12.Interest. No interest shall accrue on or be payable with respect to the payroll deductions of a Participant in the Plan.
13.Shares Reserved for Plan.
a.Number of Shares. A total of 2,500,000 shares of Common Stock have been reserved as authorized for the grant of options under the Plan. The shares of Common Stock may be newly issued shares, treasury shares or shares acquired on the open market.
b.Over-subscribed Offerings. The number of shares of Common Stock that a Participant may purchase in an Offering under the Plan may be reduced if the Offering is over-subscribed. No option granted under the Plan shall permit a Participant to purchase shares of Common Stock which, if added together with the total number of shares of Common Stock purchased by all other Participants in such Offering would exceed the total number of shares of Common Stock remaining available under the Plan. If the Committee determines that, on a particular Purchase Date, the number of shares of Common Stock with respect to which options are to be exercised exceeds the number of shares of Common Stock then available under the Plan, the Company shall make an allocation of the shares of Common Stock remaining available for purchase in as uniform a manner as practicable and as the Committee determines to be equitable.

-5-

14.Transferability. No payroll deductions credited to a Participant, nor any rights with respect to the exercise of an option or any rights to receive Common Stock hereunder may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution, or as provided in Section 17 hereof) by the Participant. Any attempt to assign, transfer, pledge or otherwise dispose of such rights or amounts shall be without effect.
15.Application of Funds. All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose to the extent permitted by applicable law, and the Company shall not be required to segregate such payroll deductions.
16.Statements. Participants will be provided with statements at least annually and shall have electronic access to account information, including the Participant’s payroll deduction amounts under the Plan, the Purchase Price of any shares of Common Stock purchased with accumulated funds, the number of shares of Common Stock purchased, and any payroll deduction amounts remaining in the Participant's notional account.
17.Designation of Beneficiary. A Participant may file, on a form supplied by the Committee, a written designation of beneficiary who, in the event of such Participant’s death, is to receive, as applicable (i) any shares of Common Stock and cash in respect of any fractional shares of Common Stock, if any, from the Participant's ESPP Share Account under the Plan and (ii) in the event of the Participant’s death more than thirty (30) days prior to the Purchase Date of an Offering Period, any cash withheld through payroll deductions and credited to the Participant’s notional account.
18.Adjustments Upon Changes in Capitalization; Dissolution or Liquidation; Corporate Transactions.
a.Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, or other change in the Company's structure affecting the Common Stock occurs, then in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, the Committee will, in such manner as it deems equitable, adjust the number of shares and class of Common Stock that may be delivered under the Plan, the Purchase Price per share and the number of shares of Common Stock covered by each outstanding option under the Plan, and the numerical limits of Section 7 and Section 13.
b.Dissolution or Liquidation. Unless otherwise determined by the Committee, in the event of a proposed dissolution or liquidation of the Company, any Offering Period then in progress will be shortened by setting a new Purchase Date on which the Offering Period will end. The new Purchase Date will occur before the date of the dissolution or liquidation. The Committee shall notify each Participant in writing, prior to the new Purchase Date, that the Purchase Date for the Participant’s option has been changed to the new Purchase Date and that the Participant’s option shall be exercised automatically on the new Purchase Date, unless prior to such date the Participant has withdrawn from an Offering then in progress or the Plan as provided in Section 10.
c.Change in Control. In the event of a Change in Control, any Offering then in progress shall be shortened by setting a new Purchase Date specified before the date of the Change in Control, unless the Committee shall, in its sole discretion, provide for the assumption or substitution of outstanding options in a manner complying with Section 424(a) of the Code. The Committee shall notify each Participant in writing, prior to any new Purchase Date, that the Purchase Date for the Participant’s option has been changed to the new Purchase Date and that the Participant’s option shall be exercised automatically on the new Purchase Date, unless prior to such date the Participant has withdrawn from an Offering then in progress or the Plan as provided in Section 10.
19.Accommodation of Local Laws; Foreign Employees.
a.The Committee may adopt rules or procedures relating to the operation and administration of this Plan to accommodate the specific requirements of local laws and procedures, tax policies or custom. Without limiting the generality of the foregoing, the Committee is specifically authorized to adopt rules and procedures regarding, among other items, the handling of payroll deductions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and other matters that vary with local requirements; however, if such varying provisions are not in accordance with the provisions of Code Section 423(b), including but
-6-

not limited to the requirement that all options granted under the Plan shall have the same rights and privileges unless otherwise provided under the Code and the regulations promulgated thereunder, then the individuals affected by such varying provisions shall be deemed to be participating under a sub-plan and not the Plan. The Committee may also adopt rules, procedures or sub-plans applicable to particular Subsidiaries or locations, which may be designed to be within or outside the scope of Code Section 423. Such rules or sub-plans may take precedence over other provisions of the Plan, but unless otherwise superseded by the terms of such rules or sub-plan, the provisions of the Plan shall govern.
a.An Eligible Employee who works for a Participating Subsidiary and is a citizen or resident of a jurisdiction other than the U.S. (without regard to whether such individual also is a citizen or resident of the U.S. or is a “resident alien” within the meaning of Section 7701(b)(1)(A) of the Code) may be excluded from participation in the Plan or an Offering if the participation of such Eligible Employee is prohibited under the laws of the applicable jurisdiction or if complying with the laws of the applicable jurisdiction would cause the Plan or an Offering to violate Section 423 of the Code.

a.Equal Rights and Privileges. In accordance with Section 423 of the Code, all Eligible Employees who are granted options under the Plan shall have the same rights and privileges.

d.Successors and Assigns. The Plan shall be binding on the Company and its successors and assigns.
e.Entire Plan. This Plan constitutes the entire plan with respect to the subject matter hereof and supersedes all prior plans with respect to the subject matter hereof.
f.Compliance with Law. The obligations of the Company with respect to payments under the Plan are subject to compliance with all applicable laws and regulations. Common Stock shall not be issued with respect to an option granted under the Plan unless the exercise of such option and the issuance and delivery of the shares of Common Stock pursuant thereto shall comply with all applicable provisions of law, including, without limitation, the Securities Act, the Exchange Act, and the requirements of any stock exchange upon which the shares may then be listed.
g.Term of Plan. The Plan shall become effective on the Effective Date and, unless terminated earlier pursuant to Section 20.8, shall have a term of ten (10) years.
h.Amendment or Termination.
a.The Committee may, in its sole discretion, amend, suspend or terminate the Plan at any time and for any reason. If the Plan is terminated, the Committee may elect to terminate all outstanding Offering Periods either immediately or once shares of Common Stock have been purchased on the next Purchase Date (which may, in the discretion of the Committee, be accelerated) or permit Offering Periods to expire in accordance with their terms (and subject to any adjustment in accordance with Section 18). If any Offering Period is terminated before its scheduled expiration, all amounts that have not been used to purchase shares of Common Stock will be returned to Participants (without interest, except as otherwise required by law) as soon as administratively practicable.
b.An amendment to the Plan must be approved by stockholders within twelve (12) months of being adopted by the Board if such amendment would increase the number of shares reserved for issuance under Section 13.1 above (other than any increase under Section 18.1) or if the amendment involves any change that would be considered the adoption of a new plan under Section 423 of the Code and Treas. Reg. Sect. 1.423-2(c)(4).

a.Governing Law. The Plan and all determinations made and actions taken pursuant hereto shall be governed by the laws of the State of Delaware without giving effect to the conflict of laws principles thereof.
b.Shareholder Approval. The Plan shall be subject to approval by the shareholders of the Company within twelve (12) months before or after the date the Plan is adopted by the Board.

d.Withholding. To the extent required by applicable Federal, state or local law, a Participant must make arrangements satisfactory to the Company for the payment of any withholding or similar tax obligations that arise in connection with the Plan.
e.Tax Qualification. Although the Company may endeavor to (a) qualify an option for specific tax treatment under the laws of the U.S. or jurisdictions outside of the U.S. or (b) avoid adverse tax treatment, the Company makes no representation to that effect and expressly disavows any covenant to maintain favorable or avoid unfavorable tax treatment, notwithstanding anything contrary in the Plan.

g.Severability. If any provision of the Plan shall for any reason be held to be invalid or unenforceable, such invalidity or unenforceability shall not affect any other provision hereof, and the Plan shall be construed as if such invalid or unenforceable provision were omitted.
h.Headings. The headings of sections herein are included solely for convenience and shall not affect the meaning of any of the provisions of the Plan.
i.Data Privacy. By participating in the Plan, each Participant agrees to the collection, processing, use and transfer of personal information by the Participating Subsidiary that employs the Participant, the Company and its designees in order to administer the Plan.

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 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

     

    

 

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 Credit Suisse Securities (USA) LLC, 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 underwriters of their right to purchase additional
Units in the Offering (the “Over-allotment Option”), if the Over-allotment Option is exercised prior to the
filing of the Current Report on Form 8-K, and (B) the Company issues a press release announcing when such separate trading shall begin.

 

2.5. Fractional Warrants. The Company shall
not issue fractional Warrants other than as part of the Units, each of which is comprised of one Ordinary Share and one-half 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. Only
whole Warrants may be exercised.

 

2.6. Private Placement Warrants and Forward Purchase
Warrants.

 

2.6.1. Private Placement Warrants. The Private
Placement Warrants and Forward Purchase 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 and Forward Purchase Warrants, including
the Ordinary Shares issuable upon exercise of the Private Placement Warrants and Forward Purchase Warrants, may not be transferred, assigned
or sold until thirty (30) days after the completion by the Company of an initial Business Combination; provided, however, that, the Private
Placement Warrants and Forward Purchase Warrants and any Ordinary Shares issued upon exercise of the Private Placement Warrants and Forward
Purchase 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 any forward purchase agreement or similar agreement or 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 the Company’s initial Business Combination;

 

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

 

    3

     

    

 

(i)                 
 with respect to Forward Purchase Warrants, such transferees as described in the Forward Purchase Agreement; or

 

(j)                 
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.

 

2.6.2. Forward Purchase Warrants. Each of
the Forward Purchase Warrants shall be identical to the Private Placement Warrants.

 

3.
Terms and Exercise of Warrants.

 

3.1. Warrant Price. Each whole Warrant shall
entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the
number of 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 (5) 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 the date that is thirty (30) days after
the first date on which the Company completes a Business Combination, 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) with respect to a redemption pursuant to Section
6.1 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) in the
event of a redemption (as set forth in Section 6 hereof), each Warrant not exercised on or before the Expiration Date shall become
void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m. New York City time on
the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided
that the Company shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders of the Warrants
and, provided further that any such extension shall be identical in duration among all the Warrants.

 

    4

     

    

 

3.3. Exercise of Warrants.

 

3.3.1. Payment. Subject to the
provisions of the Warrant and this Agreement, a Warrant may be exercised by the Registered Holder thereof by delivering to the
Warrant Agent at its corporate trust department (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised, or,
in the case of a 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 order of the Warrant Agent or wire transfers;
or

 

(b)               
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 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 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.

 

    5

     

    

 

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, 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).

 

    6

     

    

 

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, reverse share split or reclassification of Ordinary Shares or other similar event, then, on the effective
date of such consolidation, combination, reverse share split, 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 shall be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued
Price.

 

4.5. Replacement of Securities upon
Reorganization, etc. In case of any reclassification or reorganization of the issued and outstanding 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 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. 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.

 

    7

     

    

 

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

 

5.2. Procedure for Surrender of
Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and
thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the
Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that except as otherwise provided
herein or 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 and Forward Purchase 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.

 

    8

     

    

 

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. 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) or the Company has elected to require the exercise of Warrants on a “cashless basis” pursuant to
Section 7.4; 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. [Reserved].

 

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, 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 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 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.

 

    9

     

    

 

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 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. 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.

 

    10

     

    

 

7.4.2. Cashless Exercise at
Company’s Option. If the Ordinary Shares are at the time of any exercise of a 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 Warrants who exercise 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 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.

 

    11

     

    

 

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 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.

 

9.
Miscellaneous 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

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.

 

    13

     

    

 

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 or, (ii) making any amendments that are necessary in the good faith determination of the Board
(taking into account then existing market precedents for initial public offerings of special purpose acquisition companies underwritten
by bulge bracket investment banks) to allow for the Warrants to continue to be classified as equity in the Company’s financial statements;
provided that no such amendment shall increase the Warrant Price, shorten the Exercise Period or will, in the aggregate, materially affect
the legal rights of Registered Holders of the then-outstanding Public Warrants under this Agreement, (iii) removing or reducing the Company’s
ability to redeem the Warrants or (iv) 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, provided that in the case of this clause (iv) the approval by the Registered Holders of at least 50% of the then-outstanding
Public Warrants is required to make any change that adversely affects the legal rights of the Registered Holders of the Public Warrants
under this Agreement. The Company may amend the terms of the Public Warrants in a manner adverse to a Registered Holder if holders of
at least 50% of the then-outstanding Public Warrants approve of such amendment and, solely with respect to any amendment to the terms
of the Private Placement Warrants or Forward Purchase Warrants or any provision of this Agreement with respect to the Private Placement
Warrants or Forward Purchase Warrants, 50% of the number of the then outstanding Private Placement Warrants or Forward Purchase Warrants;
provided that this Agreement may be amended by the parties hereto with the vote or written consent of Registered Holders of at least 50%
of the then outstanding Private Placement Warrants or Forward Purchase Warrants without the consent of any other Registered Holder to
provide that the Private Placement Warrants or Forward Purchase Warrants (a) will remain Private Placement Warrants or Forward Purchase
Warrants, as applicable, when transferred to any party, including parties that are not Permitted Transferees, or (b) have the same terms
as the Public Warrants, subject to any applicable contractual restrictions or securities law restrictions. 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 Avista Public Acquisition Corp. II, 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 , 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 Avista Public Acquisition Corp. II (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
