WARRANT
AGREEMENT

 

This
WARRANT AGREEMENT (this “Agreement”) is made as of [_____], 2021 between Kairous Acquisition Corp. Limited, a Cayman
Islands exempted company with limited liability, with its principal executive office at Unit 9-3, Oval Tower @ Damansara, No. 685, Jalan
Damansara, 60000 Taman Tun Dr. Ismail, Kuala Lumpur, Malaysia (the “Company”), and Continental Stock Transfer &
Trust Company, a New York corporation, as warrant agent (the “Warrant Agent”).

 

WHEREAS,
the Company is engaged in a public offering (the “Public Offering”) of up to 5,750,000 units (including 750,000 units
which may be issued pursuant to an over-allotment option granted to the underwriters of the Public Offering), each unit (the “Public
Units”) comprised of one ordinary share of the Company, par value $0.0001 each (“Ordinary Share”), one-half
of one redeemable warrant and one right to acquire one-tenth of one Ordinary Share. Each whole redeemable warrant entitles the holder
to purchase one Ordinary Share at a price of $11.50 per share, subject to adjustment as described herein, and, in connection therewith,
the Company will issue and deliver up to 2,875,000 warrants (the “Public Warrants”) to the public investors in connection
with the Public Offering; and

 

WHEREAS,
the Company has filed with the Securities and Exchange Commission (the “SEC”) a Registration Statement on Form S-1,
No. 333-[_____] (as amended, the “Registration Statement”) and prospectus (the “Prospectus”), for
the registration, under the Securities Act of 1933, as amended (the “Act”) of, among other securities, the Public
Warrants; and

 

WHEREAS,
the Company will issue and deliver 125,000 warrants (or 143,750 warrants if the over-allotment option is exercised in full) underlying
a unit purchase option to Maxim Group LLC (the “Representative”) or its designees, which warrants will be identical
to the Public Warrants, subject to compliance with FINRA Rule 5110 (“Representative Warrants”); and

 

WHEREAS,
the Company has received binding commitments (the “Subscription Agreements”) from the Company’s sponsor, Kairous
Asia Limited (the “Sponsor”), to purchase, simultaneously with the closing of the Public Offering, up to an aggregate
of 270,000 units (292,500 units if the over-allotment option is exercised in full) (the “Private Units”), each containing
one Ordinary Share, one-half of one redeemable warrant (the “Private Warrants”, including the warrants underlying
the units that may be issued upon conversion of working capital loans and together with the Public Warrants and the Representative Warrants,
the “Warrants”), and one right to acquire one-tenth of one Ordinary Share. Each whole Private Warrant is exercisable
to purchase one Ordinary Share at a price of $11.50 per share, bearing the legend set forth in Exhibit B hereto; 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, 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 be issued in registered form only, shall be in substantially the form of Exhibit A
hereto, the provisions of which are incorporated herein and shall be signed by, or bear the facsimile signature of, the Chairman of the
Board of Directors or Chief Executive Officer or Chief Financial Officer and Treasurer, Secretary or Assistant Secretary of the Company
and shall bear a facsimile of the Company’s seal. 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.

 

2.2.
Uncertificated Warrants. Notwithstanding anything herein to the contrary, any Warrant, or portion thereof, may be issued as part
of, and be represented by, a Unit, and any Warrant may be issued in uncertificated or book-entry form through the Warrant Agent and/or
the facilities of The Depository Trust Company (the “Depositary”) or other book-entry depositary system, in each case
as determined by the Board of Directors of the Company or by an authorized committee thereof. Any Warrant so issued shall have the same
terms, force and effect as a certificated Warrant that has been duly countersigned by the Warrant Agent in accordance with the terms
of this Agreement.

 

2.3.
Effect of Countersignature. Except with respect to uncertificated Warrants as described above, unless and until countersigned
by the Warrant Agent pursuant to this Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

 

2.4.
Registration.

 

2.4.1.
Warrant Register. The Warrant Agent shall maintain books (“Warrant Register”) for the registration of original
issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants, 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.

 

2.4.2.
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 then registered in the Warrant Register (“registered holder”)
as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing
on the Warrant certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, and
for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

 

2.5.
Detachability of Warrants. The securities comprising the Units will not be separately transferable until the 52nd Business Day
(as defined below) or earlier with the consent of Maxim Group LLC (the “Representative”), but in no event will the
Representative allow separate trading of the securities comprising the Units until (i) the Company has filed a Current Report on Form
8-K which includes an audited balance sheet reflecting the receipt by the Company of the gross proceeds of the Public Offering including
the proceeds received by the Company from the exercise of the underwriters’ over-allotment option in the Public Offering, if the
over-allotment option is exercised prior to the filing of the Form 8-K, and (ii) the Company has issued a press release and has filed
a Current Report on Form 8-K announcing when such separate trading shall begin (the “Detachment Date”). A “Business
Day” means a day, other than a Saturday, Sunday or federal holiday, on which banks in New York City are generally open for normal
business.

 

2.6.
Private Warrant and Representative Warrants Attributes. The Private Warrants and the Representative Warrants will be identical
to the Public Warrants subject to the adjustments provided in Section 5.6.

 

3.
Terms and Exercise of Warrants

 

3.1.
Warrant Price. Each Warrant shall, when countersigned by the Warrant Agent (except with respect to uncertificated Warrants), 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 full 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 refers to the price per share
at which the Ordinary Shares may be purchased at the time a Warrant is exercised. No fractional warrants will be issued upon separation
of the units and only whole warrants will trade. Any fractional warrants will be canceled for no consideration. As a result, such Registered
Holder must hold and separate units in multiples of two to not have any fractional warrants canceled. The Company in its sole discretion
may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than twenty (20) Business
Days; provided, that the Company shall provide at least twenty (20) days’ prior written notice of such reduction to registered
holders of the Warrants and, provided further that any such reduction shall be applied consistently to all of the Warrants.

 

    	2

     

    

 

3.2.
Duration of Warrants. A Warrant may be exercised only during the period commencing 30 days after the consummation by the Company
of a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or other similar business combination
with one or more businesses or entities (“Business Combination”) (as described more fully in the Registration Statement),
and terminating at 5:00 p.m., New York City time on the earlier to occur of (i) the date that is five (5) years after the date on which
the Company consummates a Business Combination, (ii) at 5:00 p.m., New York City time on the Redemption Date as provided in Section 6.2
of this Agreement and (iii) the liquidation of the Trust Account (defined below) (“Expiration Date”). The period of
time from the date the Warrants will first become exercisable until the expiration of the Warrants shall hereafter be referred to as
the “Exercise Period.” Except with respect to the right to receive the Redemption Price (as set forth in Section 6 hereunder),
as applicable, each outstanding 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 the close of business on the Expiration Date. The Company in its sole
discretion may extend the duration of the Warrants by delaying the Expiration Date; provided, however, that the Company will provide
at least twenty (20) days’ prior written notice of any such extension to registered holders and, provided further that any such
extension shall be applied consistently to all of the Warrants.

 

3.3.
Exercise of Warrants.

 

3.3.1.
Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant, when countersigned by the Warrant Agent, may
be exercised by the registered holder thereof by surrendering it, at the office of the Warrant Agent, or at the office of its successor
as Warrant Agent, in the Borough of Manhattan, City and State of New York, with the subscription form, as set forth in the Warrant, duly
executed, and by paying in full the 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, as follows:

 

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

 

(b)
in the event of a redemption pursuant to Section 6.1 hereof in which the Company’s management has elected to force all holders
of Warrants to exercise such Warrants on a “cashless basis,” by surrendering the Warrants for that number of Ordinary Shares
equal to 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” (defined below) over the Warrant Price by (y) the Fair Market Value. Solely for purposes
of this Section 3.3.1(b), the “Fair Market Value” shall mean the average reported closing price of the Ordinary Shares for
the ten (10) trading days ending on the third trading day prior to the date of exercise on which the notice of redemption is sent to
holders of the Warrants pursuant to Section 6 hereof; or

 

(c)
in the event the registration statement required by Section 7.4 hereof is not effective and current within ninety (90) days after the
closing of a Business Combination, by surrendering such Warrants for that number of Ordinary Shares equal to 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” over the Warrant Price by (y) the Fair Market Value; provided, however, that no cashless exercise shall be permitted unless
the Fair Market Value is equal to or higher than the Warrant Price. Solely for purposes of this Section 3.3.1(c), the “Fair Market
Value” shall mean the average reported last sale price of the Ordinary Shares for the ten (10) trading days ending on the third
trading day prior to the date of exercise.

 

3.3.2.
Issuance of Ordinary Shares. As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment
of the Warrant Price (if any), the Company shall issue to the registered holder of such Warrant a certificate or certificates, or book
entry position, 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, and if such Warrant shall not have been exercised in full, a new countersigned Warrant, or book entry position, for
the number of shares as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, in no event will the Company
be required to net cash settle the Warrant exercise. No Warrant shall be exercisable for cash 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 under the securities laws of the state of residence of the registered holder of the Warrants. In the
event that the condition in the immediately preceding sentence is not satisfied with respect to a Warrant, the holder of such Warrant
shall not be entitled to exercise such Warrant for cash and such Warrant may have no value and expire worthless, in which case the purchaser
of a Unit containing such Warrants shall have paid the full purchase price for the Unit solely for the Ordinary Shares underlying such
Unit. Warrants may not be exercised by, or securities issued to, any registered holder in any state in which such exercise or issuance
would be unlawful.

 

    	3

     

    

 

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 non-assessable.

 

3.3.4.
Date of Issuance. Each person in whose name any book entry position or certificate for Ordinary Shares is issued shall for all
purposes be deemed to have become the holder of record of such 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, except
that, if the date of such surrender and payment is a date when the share transfer books of the Company or book entry system of the Warrant
Agent are closed, such person shall be deemed to have become the holder of such shares 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 cause 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 SEC
as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Warrant 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 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 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 Dividends; Split Ups. If after the date hereof, and subject to the provisions of Section 4.6 below, the number of outstanding
Ordinary Shares is increased by a share dividend payable in Ordinary Shares, or by a split up of Ordinary Shares, or other similar event,
then, on the effective date of such share dividend, split up or similar event, the number of Ordinary Shares issuable on exercise of
each Warrant shall be increased in proportion to such increase in outstanding Ordinary Shares.

 

4.2.
Aggregation of Shares. If after the date hereof, the number of 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 outstanding Ordinary Shares.

 

4.3
Extraordinary Dividends. If the Company, at any time while the Warrants (or rights to purchase the Warrants) are outstanding and
unexpired, shall pay a dividend or make a distribution in cash, securities or other assets to the holders of the Ordinary Shares on account
of such Ordinary Shares (or other shares of the Company’s capital stock into which the Warrants are convertible), other than (a)
as described in subsection 4.1 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) as a result of the repurchase of Ordinary Shares
by the Company in connection with an initial Business Combination or as otherwise permitted by the Investment Management Trust Agreement
between the Company and the Warrant Agent dated of even date herewith, (e) or as a result of the issuance of Ordinary Shares as a result
of conversion of the Rights issued in the Public Offering, or (f) in connection with the Company’s liquidation and the distribution
of its assets upon its failure to consummate a Business Combination (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 the fair market value (as determined by the Company’s board of directors, 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 4.3, “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 (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section
4 and excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of Ordinary
Shares issuable on exercise of each Warrant) does not exceed $0.50 (being 5% of the offering price of the Units in the Offering).

 

4.4
Adjustments in Exercise Price.

 

4.4.1
Whenever the number of Ordinary Shares purchasable upon the exercise of the Warrants is adjusted, as provided in Sections 4.1 and 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, (a) the numerator of which shall be the number of Ordinary Shares purchasable upon the exercise of the Warrants immediately
prior to such adjustment, and (b) the denominator of which shall be the number of Ordinary Shares so purchasable immediately thereafter,
provided that no adjustment shall be made to the Warrant Price if this would result in the Warrant Price falling below the par value
of the Ordinary Shares. In such cases, the Warrant Price would be equal to the par value of the Ordinary Shares.

 

4.4.2
If (i) the Company issues additional Ordinary Shares or securities convertible into or exercisable or exchangeable for Ordinary Shares
for capital raising purposes in connection with the closing of the initial business combination at an issue price or effective issue
price of less than $9.35 per share of Ordinary Share, with such issue price or effective issue price to be determined in good faith by
the Board, (ii) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon,
available for funding the initial business combination, and (iii) the volume weighted average trading price of the Ordinary Shares during
the 20 trading day period starting on the trading day prior to the day on which the Company consummates the initial business combination
(the “Market Value”) is below $9.35 per share, the Warrant Price shall be adjusted (to the nearest cent) to be equal
to 115% of the Market Value, and the $16.50 per share redemption triggers the Company’s right to redeem the Warrants pursuant to
Section 6.1 below shall be adjusted (to the nearest cent) to be equal to 165% of the Market Price.

 

    	5

     

    

 

4.5.
Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding Ordinary
Shares (other than a change covered by Section 4.1, 4.2 or 4.3 hereof or that solely affects the par value of the 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 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 Warrant holders 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 of stock or other securities or property (including cash) receivable upon such reclassification, reorganization,
merger or consolidation, or upon a dissolution following any such sale or transfer, that the Warrant holder would have received if such
Warrant holder had exercised his, her or its Warrant(s) immediately prior to such event. If any reclassification also results in a change
in the Ordinary Shares covered by Section 4.1, 4.2 or 4.3, then such adjustment shall be made pursuant to Sections 4.1, 4.2, 4.3, 4.4
and this Section 4.5. The provisions of this Section 4.5 shall similarly apply to successive reclassifications, reorganizations, mergers
or consolidations, sales or other transfers. In no event will the Warrant Price be reduced to less than the par value per share issuable
upon exercise of the Warrant. Notwithstanding anything to the contrary herein, in the event of any tender offer for Ordinary Shares,
the offeror shall not make any tender offer for Warrants if the effect of such offer would be to require the Warrants to be accounted
for as liabilities under applicable accounting principles.

 

4.6.
Issuance in connection with a Business Combination. If, in connection with a Business Combination, the Company (a) issues additional
Ordinary Shares or equity-linked securities at an issue price or effective issue price of less than $9.35 per share (with such issue
price or effective issue price as determined by the Company’s Board of Directors, in good faith, and in the case of any such issuance
to the Company’s initial shareholders, or their affiliates, without taking into account any founders’ shares held by them
prior to such issuance), (b) 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 Business Combination on the date of the consummation of such Business Combination
(net of redemptions), and (c) the Fair Market Value (as defined below) is below $9.35 per share, the exercise price of the warrants will
be adjusted (to the nearest cent) to be equal to 115% of the greater of (i) the Fair Market Value or (ii) the price at which the Company
issues the Ordinary Shares or equity-linked securities, and the $16.50 per share redemption trigger price will be adjusted (to the nearest
cent) to be equal to 165% of the higher of the Fair Market Value and the price at which the Company issues Ordinary Shares or equity-linked
securities. Solely for purposes of this Section 4.6, the “Fair Market Value” shall mean the volume weighted average
reported trading price of the Ordinary Shares for the twenty (20) trading days starting on the trading day prior to the date of the consummation
of the Business Combination.

 

4.7
Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares issuable upon exercise of a
Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from
such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant,
setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence
of any event specified in Sections 4.1, 4.2, 4.3, 4.4, 4.5, or 4.6, then, in any such event, the Company shall give written notice to
each Warrant holder, 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.

 

4.8.
No Fractional Warrants or Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall
not issue fractional shares upon exercise of Warrants or fractional warrants upon separation of the units and only whole warrants will
trade. 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 up to the nearest whole number
of Ordinary Shares to be issued to the Warrant holder.

 

4.9.
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. However, 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.

 

    	6

     

    

 

4.10
Other Events. In case any event shall occur affecting the Company as to which none of the provisions of preceding subsections
of this Section 4 are strictly applicable, but which would require an adjustment to the terms of the Warrants in order to (i) avoid an
adverse impact on the Warrants and (ii) effectuate the intent and purpose of this Section 4, then, in each such case, the Company shall
appoint a firm of independent public accountants, investment banking or other appraisal firm of recognized national standing, which shall
give its opinion as to whether or not any adjustment to the rights represented by the Warrants is necessary to effectuate the intent
and purpose of this Section 4 and, if they determine that an adjustment is necessary, the terms of such adjustment. provided, however,
that under no circumstances shall the Warrants be adjusted pursuant to this Section 4.10 as a result of any issuance of securities in
connection with a Business Combination. The Company shall adjust the terms of the Warrants in a manner that is consistent with any adjustment
recommended in such opinion.

 

5.
Transfer and Exchange of Warrants.

 

5.1.
Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the
Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures, in the case of certificated Warrants,
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, either in certificated form or in book
entry position, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor
one or more new Warrants, or book entry positions, as requested by the registered holder of the Warrants so surrendered, representing
an equal aggregate number of Warrants; provided, however, that in the event that a Warrant surrendered for transfer bears a restrictive
legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange therefor 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 will result
in the issuance of a warrant certificate or book-entry position for a fraction of a Warrant.

 

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, will supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

 

5.6.
Private Warrants. The Warrant Agent shall not register any transfer of Private Warrants until 30 days after the consummation by
the Company of an initial Business Combination, except for transfers (i) among the initial shareholders or to the initial shareholders’
or the Company’s officers, directors, consultants or their affiliates, (ii) to a holder’s shareholders or members upon the
holder’s liquidation, in each case if the holder is an entity, (iii) by bona fide gift to a member of the holder’s immediate
family or to a trust, the beneficiary of which is the holder or a member of the holder’s immediate family, in each case for estate
planning purposes, (iv) by virtue of the laws of descent and distribution upon death, (v) pursuant to a qualified domestic relations
order, (vi) to the Company for no value for cancellation in connection with the consummation of a Business Combination, (vii) in connection
with the consummation of a Business Combination by private sales at prices no greater than the price at which the Private Warrants were
originally purchased, (viii) in the event of the Company’s liquidation prior to its consummation of an initial Business Combination
or (ix) in the event that, subsequent to the consummation of an initial Business Combination, the Company completes a liquidation, merger,
share exchange or other similar transaction which results in all of the Company’s shareholders having the right to exchange their
Ordinary Shares for cash, securities or other property, in each case (except for clauses (vi), (viii) or (ix) or with the Company’s
prior written consent) on the condition that prior to such registration for transfer, the Warrant Agent shall be presented with written
documentation pursuant to which each transferee (each, a “Permitted Transferee”) or the trustee or legal guardian
for such transferee agrees to be bound by the transfer restrictions contained in this section and any other applicable agreement the
transferor is bound by.

 

    	7

     

    

 

5.7.
Transfers prior to Detachment. Prior to the Detachment Date, the Public Warrants may be transferred or exchanged only together
with the Unit in which such Warrants are included, and only for the purpose of effecting, or in conjunction with, a transfer or exchange
of such Units. Furthermore, each transfer of a Unit on the register relating to such Unit shall operate also to transfer the Warrants
included in such Unit. Notwithstanding the foregoing, the provisions of this Section 5.7 shall have no effect on any transfer of Warrants
on or after the Detachment Date.

 

6.
Redemption.

 

6.1.
Redemption. 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 the notice referred to in Section 6.2, at the price of $0.01 per Warrant (“Redemption
Price”), provided that the closing price of the Ordinary Shares equals or exceeds $16.50 per share (subject to adjustment in
accordance with Section 4 hereof), on each of twenty (20) trading days within any thirty (30) trading day period commencing after the
Warrants become exercisable and ending on the third trading day prior to the date on which notice of redemption is given and provided
that there is an effective registration statement covering the Ordinary Shares issuable upon exercise of the Warrants, and a current
prospectus relating thereto, available throughout the 30-day redemption or the Company has elected to require the exercise of the Warrants
on a “cashless basis” pursuant to subsection 3.3.1(b); provided, however, that if and when the Warrants become redeemable
by the Company, the Company may not exercise such redemption right if the issuance of Ordinary Shares upon exercise of the Warrants is
not exempt from registration or qualification under applicable state blue sky laws or the Company is unable to effect such registration
or qualification.

 

6.2.
Date Fixed for, and Notice of, Redemption. In the event the Company shall elect to redeem all of the Warrants, the Company shall
fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first class mail, postage
prepaid, by the Company not less than thirty (30) days prior to the Redemption Date to the registered holders of the Warrants to be redeemed
at their last addresses as they shall appear on the registration books. Any notice mailed in the manner herein provided shall be conclusively
presumed to have been duly given whether or not the registered holder received such notice.

 

6.3.
Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance
with Section 3 of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2
hereof and prior to the Redemption Date. In the event the Company determines to require all holders of Warrants to exercise their Warrants
on a “cashless basis” pursuant to Section 3.3.1(b), the notice of redemption will contain the information necessary to calculate
the number of Ordinary Shares to be received upon exercise of the Warrants, including the “Fair Market Value” (as such term
is defined in subsection 3.3.1(b) hereof) in such case. On and after the Redemption Date, the record holder of the Warrants shall have
no further rights except to receive, upon surrender of the Warrants, the Redemption Price.

 

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.

 

    	8

     

    

 

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 will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.

 

7.4.
Registration of Ordinary Shares. The Company agrees that as soon as practicable after the closing of its initial Business Combination,
it shall use its best efforts to file with the Securities and Exchange Commission a registration statement for the registration, under
the Act, of the Ordinary Shares issuable upon exercise of the Warrants, and it shall use its best efforts to take such action as is necessary
to register or qualify for sale, in those states in which the Warrants were initially offered by the Company and in those states where
holders of Warrants then reside, the Ordinary Shares issuable upon exercise of the Warrants, to the extent an exemption is not available.
The Company will use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement,
and a current prospectus relating thereto, until the expiration of the Warrants in accordance with the provisions of this Agreement.
If any such registration statement has not been declared effective by the 90th day following the closing of the Business Combination,
holders of the Warrants shall have the right, during the period beginning on the 91st day after the closing of the Business Combination
and ending upon such registration statement being declared effective by the Securities and Exchange Commission, and during any other
period when the Company shall fail to have maintained an effective registration statement covering the Ordinary Shares issuable upon
exercise of the Warrants, to exercise such Warrants on a “cashless basis” as determined in accordance with Section 3.3.1(c).
The Company shall 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 Section 7.4 is not required
to be registered under the Act and (ii) the Ordinary Shares issued upon such exercise will be freely tradable under U.S. federal securities
laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Act) of the Company and, accordingly, will not
be required to bear a restrictive legend. For the avoidance of any doubt, unless and until all of the Warrants have been exercised or
have expired, the Company shall continue to be obligated to comply with its registration obligations under the first three sentences
of this Section 7.4. The provisions of this Section 7.4 may not be modified, amended, or deleted without the prior written consent of
the Representative.

 

8.
Concerning the Warrant Agent and Other Matters.

 

8.1.
Payment of Taxes. The Company will 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 Warrants, but the Company shall not
be obligated to pay any transfer taxes in respect of the Warrants or such Ordinary 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 the Warrant
(who shall, with such notice, submit his Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme
Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost.
Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the
laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York,
and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority.
After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations
of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed;
but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of
the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant
Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all
instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers,
rights, immunities, duties, and obligations.

 

    	9

     

    

 

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

 

8.3.
Fees and Expenses of Warrant Agent.

 

8.3.1.
Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder
and will 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 or Chairman of the Board of Directors 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 fraud, gross negligence, willful misconduct or bad faith.
The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and
reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement except as a result of the
Warrant Agent’s fraud, gross negligence, willful misconduct, or bad faith.

 

8.4.3.
Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the
validity or execution of any Warrant (except its countersignature thereof); nor shall it be responsible for any breach by the Company
of any covenant or condition contained in this Agreement or in any Warrant; nor shall it 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, the Amended and Restated
Memorandum and Articles of Association of the Company, or any Warrant or as to whether any Ordinary Shares will, when issued, be valid
and fully paid and non-assessable.

 

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

9.3.
Applicable Law and Exclusive Forum. The validity, interpretation, and performance of this Agreement and of the Warrants shall
be governed in all respects by the laws of the State of New York, without giving effect to conflicts of law principles that would result
in the application of the substantive laws of another jurisdiction. Each of the Company and the Warrant Agent 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.
Each of the Company and the Warrant Agent 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 courts of the United States of America have exclusive jurisdiction
or any complaint asserting a cause of action arising under the Securities Act against us or any of our directors, officers, other employees
or agents. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability
created by the Exchange Act or the rules and regulations thereunder. Any such process or summons to be served upon the Company may be
served by transmitting a copy thereof by registered or certified mail, return receipt requested, postage prepaid, addressed to it at
the address set forth in Section 9.2 hereof. Such mailing shall be deemed personal service and shall be legal and binding upon the Company
in any action, proceeding or claim.

 

9.4.
Persons Having Rights under this Agreement. Nothing in this Agreement expressed and nothing that may be implied from any of the
provisions hereof is intended, or shall be construed, to confer upon, or give to, any person or corporation other than the parties hereto
and the registered holders of the Warrants and, for the purposes of Sections 7.4, 9.4 and 9.8 hereof, the Representative, any right,
remedy, or claim under or by reason of this Warrant Agreement or of any covenant, condition, stipulation, promise, or agreement hereof.
The Representative shall be deemed to be a third-party beneficiary of this Agreement with respect to Sections 7.4, 9.4 and 9.8 hereof.
All covenants, conditions, stipulations, promises, and agreements contained in this Warrant Agreement shall be for the sole and exclusive
benefit of the parties hereto (and the Representative with respect to the Sections 7.4, 9.4 and 9.8 hereof) and their successors and
assigns and of the registered holders of the Warrants.

 

9.5.
Examination of the Warrant Agreement. A copy of this Agreement shall be available at all reasonable times at the office of the
Warrant Agent in the Borough of Manhattan, City and State of New York, for inspection by the registered holder of any Warrant. The Warrant
Agent may require any such holder to submit his Warrant for inspection by it.

 

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

 

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

 

9.8
Amendments. This Agreement may be amended by the parties hereto without the consent of any registered holder for the purpose of
curing any ambiguity, including to conform the provisions hereof to the description of the terms of the Warrants and this Agreement set
forth in the Prospectus, or curing, correcting or supplementing any defective provision contained herein or adding or changing any other
provisions with respect to matters or questions arising under this Agreement as the parties may deem necessary or desirable and that
the parties deem shall not adversely affect the interest of the registered holders. All other modifications or amendments, including
any amendment to increase the Warrant Price or shorten the Exercise Period, shall require the written consent or vote of the registered
holders of a majority of the then outstanding 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. The
provisions of this Section 9.8 may not be modified, amended or deleted without the prior written consent of the Representative.

 

9.9
Trust Account Waiver. The Warrant Agent acknowledges and agrees that it shall not make any claims or proceed against the trust
account established by the Company in connection with the Public Offering (as more fully described in the Registration Statement) (“Trust
Account”), including by way of set-off, and shall not be entitled to any funds in the Trust Account under any circumstance.
In the event that the Warrant Agent has a claim against the Company under this Agreement, the Warrant Agent will pursue such claim solely
against the Company and not against the property held in the Trust Account.

 

9.10
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.

RIGHTS
AGREEMENT

 

This
Rights Agreement (this “Agreement”) is made as of [*], 2021 between Kairous Acquisition Corp. Limited, a Cayman Islands
company, with its principal executive office at Unit 9-3, Oval Tower @ Damansara, No. 685, Jalan Damansara, 60000 Taman Tun Dr. Ismail,
Kuala Lumpur, Malaysia (the “Company”), and Continental Stock Transfer & Trust Company, a New York corporation
(the “Right Agent”).

 

WHEREAS,
the Company has received a firm commitment from Maxim Group LLC (“Maxim”), as representative of the several underwriters,
to purchase up to an aggregate of 5,000,000 units, each unit (“Unit”) comprised of one ordinary share of the Company, par
value $0.0001 per share (the “Ordinary Shares”), one-half (1/2) of one redeemable warrant entitling the holder thereof
to purchase one Ordinary Share, and one right to receive one-tenth of one Ordinary Share (a “Public Right”). Upon
the happening of the triggering event described herein, and in connection therewith, the Company will issue and deliver up to an aggregate
of 5,750,000 Public Rights upon consummation of such public offering, 750,000 of which are attributable to the over-allotment option
(“Public Offering”);

 

WHEREAS,
simultaneously with the consummation of the Public Offering, the Company will issue and deliver up to an aggregate of 270,000 rights
(or 292,500 rights if the over-allotment option is exercised in full) underlying private units (the “Private Rights”);

 

WHEREAS,
in connection with the Public Offering, the Company will issue and deliver up to 287,500 rights (underlying unit purchase options) to
Maxim or its designees (“Maxim Rights”);

 

WHEREAS,
the Company may issue up to an additional 100,000 Rights, which will be identical to the Private Rights, in consideration of certain
working capital loans that may be made by Kairous Asia Limited, the Company’s sponsor, or the Company’s officers, directors
or affiliates (together with the Public Rights, the Private Rights, the Maxim Rights, and along with such other rights as the Company
issues from time to time hereunder, the “Rights”);

 

WHEREAS,
the Company has filed with the Securities and Exchange Commission (the “SEC”) a Registration Statement on Form S-1,
File No. 333-[_______] (“Registration Statement”), for the registration, under the Securities Act of 1933, as amended
(“Act”) of, among other securities, the Public Rights and the Ordinary Shares issuable to the holders of the Public
Rights;

 

WHEREAS,
the Company desires the Right Agent to act on behalf of the Company, and the Right Agent is willing to so act, in connection with the
issuance, registration, transfer and exchange of the Rights;

 

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

 

WHEREAS,
all acts and things have been done and performed which are necessary to make the Rights, when executed on behalf of the Company and countersigned
by or on behalf of the Right Agent, as provided herein, the valid, binding and legal obligations of the Company, and to authorize the
execution and delivery of this Agreement.

 

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

 

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

 

2.
Rights.

 

2.1
Form of Rights. Each Right shall be issued in registered form only, shall be in substantially the form of Exhibit A hereto, the
provisions of which are incorporated herein and shall be signed by, or bear the facsimile signature of, the Chairman of the Board or
any Director or Chief Executive Officer and Treasurer, Secretary or Assistant Secretary of the Company and shall bear a facsimile of
the Company’s seal. In the event the person whose facsimile signature has been placed upon any Right shall have ceased to serve
in the capacity in which such person signed the Right before such Right 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.

 

    	 

     

    

 

2.2
Effect of Countersignature. Unless and until countersigned by the Right Agent pursuant to this Agreement, a Right shall be invalid
and of no effect and may not be exchanged for Ordinary Shares.

 

2.3
Registration.

 

2.3.1
Right Register. The Right Agent shall maintain books (“Right Register”) for the registration of original issuance
and the registration of transfer of the Rights. Upon the initial issuance of the Rights, the Right Agent shall issue and register the
Rights in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to
the Right Agent by the Company.

 

2.3.2
Registered Holder. Prior to due presentment for registration of transfer of any Right, the Company and the Right Agent may deem
and treat the person in whose name such Right shall be registered upon the Right Register (“registered holder”) as
the absolute owner of such Right and of each Right represented thereby (notwithstanding any notation of ownership or other writing on
the Right Certificate made by anyone other than the Company or the Right Agent), for the purpose of the exchange thereof, and for all
other purposes, and neither the Company nor the Right Agent shall be affected by any notice to the contrary.

 

2.4
Detachability of Rights. The securities comprising the Units, including the Rights, will not be separately transferable until
the fifty-second (52nd) day after the date of the prospectus unless Maxim informs the Company of its decision to allow earlier
separate trading, but in no event will separate trading of the securities comprising the Units begin until (i) the Company files a Current
Report on Form 8-K which includes an audited balance sheet reflecting the receipt by the Company of the gross proceeds of the Public
Offering including the proceeds received by the Company from the exercise of the over-allotment option, if the over-allotment option
is exercised on the date hereof, and (ii) the Company issues a press release and files a Current Report on Form 8-K announcing when such
separate trading shall begin.

 

3.
Terms and Exchange of Rights.

 

3.1
Rights. Each Right shall entitle the holder thereof to receive one-tenth of one Ordinary Share upon the happening of the Exchange
Event (described below). No additional consideration shall be paid by a holder of Rights in order to receive his, her or its Ordinary
Shares upon the Exchange Event as the purchase price for such Ordinary Shares has been included in the purchase price for the Units.
In no event will the Company be required to net cash settle the Rights or issue fractional Ordinary Shares.

 

3.2
Exchange Event. The Exchange Event shall be the Company’s consummation of an initial Business Combination (as defined in
the Company’s Amended and Restated Memorandum and Articles of Association).

 

3.3
Exercise of Rights.

 

3.3.1
Issuance of Certificates. As soon as practicable upon the occurrence of the Exchange Event, the Company shall direct holders of
the Rights to return their Rights Certificates to the Right Agent. If the Company is not the surviving entity in a Business Combination,
the holder of Rights must affirmatively elect to such conversion. Upon receipt of a valid Rights Certificate, the Company shall issue
to the registered holder of such Right(s) a certificate or certificates for the number of full 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. Notwithstanding the foregoing, or any provision contained
in this Agreement to the contrary, in no event will the Company be required to net cash settle the Rights. The Company shall not issue
fractional shares upon exchange of Rights. At the time of the Exchange Event, the Company will instruct the Right Agent to round down
to the nearest whole Ordinary Share or otherwise inform it how fractional shares will be addressed in accordance with Cayman Islands
law.

 

    	2 

     

    

 

3.3.2
Valid Issuance. All Ordinary Shares issued upon an Exchange Event in conformity with this Agreement shall be validly issued, fully
paid and non-assessable.

 

3.3.3
Date of Issuance. Each person in whose name any such certificate for Ordinary Shares is issued shall for all purposes be deemed
to have become the holder of record of such shares on the date of the Exchange Event, irrespective of the date of delivery of such certificate.

 

3.3.4
Company Not Surviving Following Exchange Event. If the Exchange Event results in the Company not continuing as a publicly held
reporting entity, the definitive agreement will provide for the holders of Rights to receive the same per share consideration as the
holders of the Ordinary Shares will receive in with the Exchange Event, for the number of shares such holder is entitled to pursuant
to Section 3.1 above.

 

3.4
Duration of Rights. If the Exchange Event does not occur within 12 months from the closing of the Public Offering (or up to 21
months from the closing of the Public Offering if the Company extends the period of time to consummate a Business Combination, as described
in the Registration Statement), and such Business Combination has not yet been consummated within the applicable time period, the Rights
shall expire and shall be worthless; provided that, for as long as any of the Maxim Right are held by Maxim, or its designees or affiliates,
such Rights may not be converted after five years, from the effective date of the Registration Statement.

 

4.
Transfer and Exchange of Rights.

 

4.1
Registration of Transfer. The Right Agent shall register the transfer, from time to time, of any outstanding Right upon the Right
Register, upon surrender of such Right for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate
instructions for transfer. Upon any such transfer, a new Right representing an equal aggregate number of Rights shall be issued and the
old Right shall be cancelled by the Right Agent. The Rights so cancelled shall be delivered by the Right Agent to the Company from time
to time upon request.

 

4.2
Procedure for Surrender of Rights. Rights may be surrendered to the Right Agent, together with a written request for exchange
or transfer, and thereupon the Right Agent shall issue in exchange therefor one or more new Rights as requested by the registered holder
of the Rights so surrendered, representing an equal aggregate number of Rights; provided, however, that in the event that a Right surrendered
for transfer bears a restrictive legend, the Right Agent shall not cancel such Right and issue new Rights in exchange therefor until
the Right Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the
new Rights must also bear a restrictive legend. Extraordinary Dividends.

 

4.3
Fractional Rights. The Right Agent shall not
be required to effect any registration of transfer or exchange which will result in the issuance of a Right Certificate for a fraction
of a Right.

 

4.4
Service Charges. No service charge shall be made for any exchange or registration of transfer of Rights.

 

4.5
Adjustments to Conversion Ratios. The number of Ordinary Shares that the holders of Rights are entitled to receive as a result
of the occurrence of an Exchange Event shall be equitably adjusted to reflect appropriately the effect of any share split, reverse share
split, share dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with
respect to the Ordinary Shares occurring on or after the date hereof and prior to the Exchange Event.

 

4.6
Right Execution and Countersignature. The Right Agent is hereby authorized to countersign and to deliver, in accordance with the
terms of this Agreement, the Rights required to be issued pursuant to the provisions of this Section 4, and the Company, whenever required
by the Right Agent, will supply the Right Agent with Rights duly executed on behalf of the Company for such purpose.

5.
Other Provisions Relating to Rights of Holders of
Rights.

 

5.1
No Rights as Shareholder. Until exchange of a Right for Ordinary Shares as provided for herein, a Right 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

 

5.2
Lost, Stolen, Mutilated, or Destroyed Rights. If any Right is lost, stolen, mutilated, or destroyed, the Company and the Right
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
Right, include the surrender thereof), issue a new Right of like denomination, tenor, and date as the Right so lost, stolen, mutilated,
or destroyed. Any such new Right shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost,
stolen, mutilated, or destroyed Right shall be at any time enforceable by anyone.

 

5.3
Reservation of Ordinary Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued
Ordinary Shares that will be sufficient to permit the exchange of all outstanding Rights issued pursuant to this Agreement.

 

6.
Concerning the Right Agent and Other Matters.

 

6.1
Payment of Taxes. The Company will from time to time promptly pay all taxes and charges that may be imposed upon the Company or
the Right Agent in respect of the issuance or delivery of Ordinary Shares upon the exchange of Rights, but the Company shall not be obligated
to pay any transfer taxes in respect of the Rights or such shares.

 

6.2
Resignation, Consolidation, or Merger of Right Agent.

 

6.2.1
Appointment of Successor Right Agent. The Right 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 Right Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a
successor Right Agent in place of the Right Agent. If the Company shall fail to make such appointment within a period of 30 days after
it has been notified in writing of such resignation or incapacity by the Right Agent or by the holder of the Right (who shall, with such
notice, submit his, her or its Right for inspection by the Company), then the holder of any Right may apply to the Supreme Court of the
State of New York for the County of New York for the appointment of a successor Right Agent at the Company’s cost. Any successor
Right Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State
of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and authorized
under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment,
any successor Right Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor
Right Agent with like effect as if originally named as Right Agent hereunder, without any further act or deed; but if for any reason
it becomes necessary or appropriate, the predecessor Right Agent shall execute and deliver, at the expense of the Company, an instrument
transferring to such successor Right Agent all the authority, powers, and rights of such predecessor Right Agent hereunder; and upon
request of any successor Right 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 Right Agent all such authority, powers, rights, immunities, duties,
and obligations.

 

6.2.2
Notice of Successor Right Agent. In the event a successor Right Agent shall be appointed, the Company shall give notice thereof
to the predecessor Right Agent and the transfer agent for the Ordinary Shares not later than the effective date of any such appointment.

 

6.2.3
Merger or Consolidation of Right Agent. Any corporation into which the Right Agent may be merged or with which it may be consolidated
or any corporation resulting from any merger or consolidation to which the Right Agent shall be a party shall be the successor Right
Agent under this Agreement without any further act.

duties hereunder.

 

6.3.2
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 Right Agent for the carrying
out or performing of the provisions of this Agreement.

 

6.4
Liability of Right Agent.

 

6.4.1
Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Right 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 or Chief Financial Officer and delivered to the Right Agent. The Right
Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement.

 

6.4.2
Indemnity. The Right Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith. Subject
to Section 6.6, the Company agrees to indemnify the Right Agent and save it harmless against any and all liabilities, including judgments,
costs and reasonable counsel fees, for anything done or omitted by the Right Agent in the execution of this Agreement except as a result
of the Right Agent’s gross negligence, willful misconduct, or bad faith.

 

6.4.3
Exclusions. The Right Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the
validity or execution of any Right (except its countersignature thereof); nor shall it be responsible for any breach by the Company of
any covenant or condition contained in this Agreement or in any Right; 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 Right or as
to whether any Ordinary Shares will, when issued, be valid and fully paid and non-assessable.

 

6.5
Acceptance of Agency. The Right Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon
the terms and conditions herein set forth.

 

6.6
Waiver. The Right Agent hereby waives any right of set-off or any other right, title, interest or claim of any kind (“Claim”)
in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of the date
hereof, by and between the Company and the Right Agent as trustee thereunder) and hereby agrees not to seek recourse, reimbursement,
payment or satisfaction for any Claim against the Trust Account for any reason whatsoever.

7.3
Applicable Law. The validity, interpretation, and performance of this Agreement and of the Rights shall be governed in all respects
by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the
substantive laws of another jurisdiction. Each of the Company and the Right Agent 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. Each of the Company and the Right Agent hereby waives any objection to such exclusive jurisdiction and that such
courts represent an inconvenient forum. Notwithstanding the foregoing, this exclusive forum provision shall not apply to suits brought
to enforce a duty or liability created by the Securities Exchange Act of 1934 (“Exchange Act”), any other claim for which
the federal courts have exclusive jurisdiction or any complaint asserting a cause of action arising under the Securities Act against
us or any of our directors, officers, other employees or agents. Section 27 of the Exchange Act creates exclusive federal jurisdiction
over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Any such
process or summons to be served upon the Company may be served by transmitting a copy thereof by registered or certified mail, return
receipt requested, postage prepaid, addressed to it at the address set forth in Section 7.2 hereof. Such mailing shall be deemed personal
service and shall be legal and binding upon the Company in any action, proceeding or claim.

 

7.4
Persons Having Rights under this Agreement. Nothing in this Agreement expressed and nothing that may be implied from any of the
provisions hereof is intended, or shall be construed, to confer upon, or give to, any person or corporation other than the parties hereto
and the registered holders of the Rights and, for the purposes of Sections 3.1, 3.2, 7.4 and 7.8 hereof, Maxim, any right, remedy, or
claim under or by reason of this Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. Maxim shall be deemed
to be a third-party beneficiary of this Agreement with respect to Sections 3.1, 3.2, 7.4 and 7.8 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 Maxim with
respect to Sections 3.1, 3.2, 7.4 and 7.8 hereof) and their successors and assigns and of the registered holders of the Rights.

 

7.5
Examination of this Agreement. A copy of this Agreement shall be available at all reasonable times at the office of the Right
Agent in the Borough of Manhattan, City and State of New York, for inspection by the registered holder of any Right. The Right Agent
may require any such holder to submit his, her or its Right for inspection by it.

 

7.6
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.

7.7
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.

 

7.8
Amendments. This Agreement may be amended by the parties hereto without the consent of any registered holder for the purpose of
curing any ambiguity, or of curing, correcting or supplementing any defective provision contained herein or adding or changing any other
provisions with respect to matters or questions arising under this Agreement as the parties may deem necessary or desirable and that
the parties deem shall not adversely affect the interest of the registered holders. All other modifications or amendments shall require
the written consent or vote of the registered holders of a majority of the then outstanding Rights. The provisions of this Section 7.8
may not be modified, amended or deleted without the prior written consent of Maxim.

 

7.9
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.
