Dated as of [●], 2021


 


THIS WARRANT AGREEMENT (this “Agreement”),
dated as of [●], 2021, is by and between Spring Valley Acquisition Corp. II, a Cayman Islands exempted company (the “Company”),
and Continental Stock Transfer & Trust Company, a New York limited purpose trust company, as warrant agent (the “Warrant
Agent,” also referred to herein as the “Transfer Agent”).


 


WHEREAS, on [●], 2021, the Company entered
into that certain Private Placement Warrants Purchase Agreement with Spring Valley Acquisition Sponsor II, LLC, a Delaware limited liability
company (the “Sponsor”), pursuant to which the Sponsor will purchase an aggregate of 7,000,000 warrants (or up to 7,600,000
warrants if the over-allotment option is exercised in full) simultaneously with the closing of the Offering (as defined below) (and the
closing of the over-allotment option, if applicable) bearing the legend set forth in Exhibit A hereto (the “Private
Placement Warrants”) at a purchase price of $1.00 per Private Placement Warrant;


 


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


 


WHEREAS, the Company is engaged in an initial public
offering (the “Offering”) of units of the Company’s equity securities, each such unit comprised of one Class A
ordinary share of the Company, par value $0.0001 per share (“Ordinary Shares”), and one-half of one public warrant
(the “Units”) and, in connection therewith, has determined to issue and deliver up to 11,500,000 warrants (including
up to 1,500,000 warrants subject to the Over-allotment Option) to public investors in the Offering;


 


WHEREAS, the Company has filed with the U.S. Securities
and Exchange Commission (the “Commission”) a registration statement on Form S-1, File No. 333-2531569 (the
 “Registration Statement”) and prospectus (the “Prospectus”), for the registration, under the Securities
Act of 1933, as amended (the “Securities Act”), of the issuance of the Units, the Warrants and the Ordinary Shares
included in the Units;


 


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 and exercise of the Warrants;


 






    


     


    

 


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


 


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


 


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 express 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 the initial issuance
of the Warrants 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. If requested, the Registered Holder of a Warrant shall be issued a definitive
certificate in physical form evidencing such Warrants which shall be in the form attached hereto as Exhibit B.


 


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


 






    2


     


    

 


2.3.2            Registered
Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat
the person in whose name such Warrant is registered in the Warrant Register (the “Registered Holder”) as the absolute
owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on any physical
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.


 


3.             Terms
and Exercise of Warrants.


 


3.1           Warrant
Price. Each whole Warrant, when countersigned by the Warrant Agent, 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 penultimate sentence of this Section 3.1.
The term “Warrant Price” as used in this Agreement shall mean the price per share at which each Ordinary Share 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 twenty (20) Business Days, provided, that the Company shall provide
at least twenty (20) days prior written notice of such reduction to Registered Holders of the Warrants and, provided, further, that any
such reduction shall be identical among all of the Warrants. The term “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.


 


3.2           Duration
of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”) commencing on the later
of: (i) the date that is thirty (30) days after the first date on which the Company completes a merger, consolidation, share exchange,
asset acquisition, share purchase, reorganization or similar business combination, involving the Company and one or more businesses or
entities (a “Business Combination”), or (ii) the date that is twelve (12) months from the date of the closing
of the Offering and terminating at the earlier to occur of; (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 and (y) the liquidation of the Company (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 hereof, with respect to an effective registration statement. Each Warrant not exercised on or
before the Expiration Date shall become null and void, and all rights thereunder and all rights in respect thereof under this Agreement
shall cease at 5:00 p.m., New York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the
Warrants by delaying the Expiration Date; provided, that the Company shall provide at least twenty (20) days prior written notice of
any such extension to Registered Holders of the Warrants and, provided, further, that any such extension shall be identical in duration
among all the Warrants.


 






    3


     


    

 


3.3           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 (if evidenced by definitive certificate) 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 full 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 Share, as follows:


 


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


 


    (b)            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 10-Day Average Closing Price, as of the date prior to the
date on which notice of exercise is sent or given to the Warrant Agent, less the Warrant Price by (y) the 10-Day Average Closing
Price. “10-Day Average Closing Price” means, as of any date, the average last reported sale price of the Ordinary Shares
as reported during the ten (10) trading day period ending on the trading day prior to such date. “Last Reported Sale Price”
shall mean the last reported sale price of the Ordinary Shares on the date prior to the date on which notice of exercise of the Warrant
is sent to the Warrant Agent; or


 


    (c)            as
provided in Section 6.4 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) hereof), the Company shall issue to the Registered Holder
of such Warrant a book-entry position or certificate, as applicable, 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, 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 Ordinary 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 Warrants is then effective and a prospectus relating thereto is current 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 has been registered, qualified or deemed to
be exempt from registration or qualification under the securities laws of the state of residence of the Registered Holder of the Warrants.
In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Warrant, the holder of
such Warrant shall not be entitled to exercise such Warrant and such Warrant may have no value and expire worthless, in which case the
purchaser of a Unit containing such Warrants shall have paid the full purchase price for the Unit solely for the Ordinary Shares underlying
such Unit. In no event will the Company be required to net cash settle the Warrant exercise. 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. Notwithstanding anything in this Agreement, for so long as any Warrant is held by the Sponsor, such Warrant will not be exercisable
more than five (5) years from the effective date of the Registration Statement, in accordance with Financial Industry Regulatory
Authority, Inc. (“FINRA”) Rules. In addition, no such Warrant will contain terms which allow the Sponsor to receive
or accrue cash dividends prior to the exercise of the Warrants.


 






    4


     


    

 


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, as applicable, for Ordinary Shares is issued 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 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 Ordinary Shares at the close of business on the next succeeding date on which the share transfer books or book-entry system of
the Warrant Agent are open.


 


3.3.5            Maximum
Percentage. A holder of a Warrant may notify the Company in writing in the event it elects to be subject to the provisions contained
in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection 3.3.5 unless he, she or it
makes such election. If the election is made by a holder, the Warrant Agent shall not effect the exercise of the holder’s Warrant,
and such holder shall not have the right to exercise such Warrant, to the extent that after giving effect to such exercise, such person
(together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially own in excess of 9.8%,
or such other amount as a holder may specify (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 issued and outstanding Ordinary Shares,
the holder may rely on the number of issued and 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 the Transfer
Agent setting forth the number of Ordinary Shares issued and 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.


 






    5


     


    

 


3.3.6            Lock-up
of Private Placement Warrants. The Warrants held by the Sponsor and the Ordinary Shares that are issuable upon exercise of such Warrants
have been deemed compensation by the FINRA and are therefore subject to a 180-day lock-up pursuant to FINRA Rule 5110(e)(1), commencing
on the effective date of the Registration Statement. Pursuant to FINRA Rule 5110(e)(1), these securities will not be sold during
the Offering, or sold, transferred, assigned, pledged, or hypothecated, or be the subject of any hedging, short sale, derivative, put
or call transaction that would result in the economic disposition of the securities by any person for a period of 180 days immediately
following the effective date of the Registration Statement or commencement of sales of the Offering, except to any underwriter and selected
dealer participating in the Offering and their bona fide officers or partners (provided that all securities so transferred remain subject
to the lockup restriction above for the remainder of the time period) or pursuant to another exception to the applicability of FINRA Rule 5110(e)(1).


 


4.             Adjustments.


 


4.1           Share
Dividends.


 


4.1.1            Share
Dividends and Split-Ups. If after the date hereof, and subject to the provisions of Section 4.6 hereof, the number of
issued and 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 the issued and outstanding Ordinary Shares. A rights
offering to holders of Ordinary Shares entitling holders to purchase Ordinary Shares at a price less than the “Fair Market Value”
(as defined below) shall be deemed a share dividend 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 Fair Market Value. For purposes of this subsection 4.1.1, if the rights
offering is for securities convertible into or exercisable for Ordinary Shares, in determining the price payable for the 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. “Fair Market Value” means the 10-Day Average Closing Price as of the first (1st) 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.
Notwithstanding anything to the contrary herein, no Ordinary Shares shall be issued at less than their par value.


 






    6


     


    

 


4.1.2            Extraordinary
Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or make a distribution
in cash, securities or other assets to the holders of the Ordinary Shares on account of such Ordinary Shares (or other shares of the Company’s
share capital 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 Ordinary Shares in connection with
a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association to modify
the substance or timing of the Company’s obligation to redeem 100% of the Ordinary Shares if the Company does not complete its initial
Business Combination within the period set forth in the Company’s amended and restated memorandum and articles of association, or
(e) in connection with the redemption of the Ordinary Shares included in the Units sold in the Offering upon the Company’s
failure to complete the Company’s initial 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/or the fair market value (as determined by 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 (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.


 


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 Warrant Price. Whenever the number of Ordinary Shares purchasable upon the exercise of the Warrants is adjusted, as provided in
Section 4.1 or 4.2 hereof, 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.


 






    7


     


    

 


4.4           Replacement
of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the issued and outstanding Ordinary
Shares (other than a change covered by Section 4.1 or 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 entity in which any “person” or
 “group” (as such terms are used in Section 13(d) and 14(d) of the Exchange Act) acquires more than 50% of
the voting power of the Company’s securities, 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, 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 of stock or other securities or property (including cash) receivable upon such reclassification, reorganization,
merger or consolidation, 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; provided, further, that if less than seventy percent (70%)
of the consideration receivable by the holders of the Ordinary Shares in the applicable event is payable in the form of shares in the
successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market,
or is to be so listed for trading or quoted immediately following such event, and if the Registered Holder properly exercises the Warrant
within thirty (30) days following the public disclosure of the consummation of such applicable event by the Company pursuant to a current
report on Form 8-K filed with the Commission, the Warrant Price shall be reduced by an amount (in dollars) equal to the difference
of (i) the Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below)
(but in no event less than zero) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant
Value” means the value of a Warrant immediately prior to the consummation of the applicable event based on the Black-Scholes
Warrant Model for an uncapped American Call on Bloomberg Financial Markets (“Bloomberg”), as calculated by an accounting,
appraisal, investment banking firm or consultant of nationally recognized standing that is, in the good faith judgment of the Board,
qualified to make such calculation. For purposes of calculating such amount, (1) the price of each Ordinary Share shall be the average
last reported sale price of the Ordinary Shares as reported during the ten (10) trading day period ending on the trading day prior
to the applicable event, (2) the assumed volatility shall be the ninety (90) day volatility obtained from the HVT function on Bloomberg
determined as of the trading day immediately prior to the day of the announcement of the applicable event, and (3) the assumed risk-free
interest rate shall correspond to the U.S. Treasury rate for a period equal to the remaining term of the Warrant. “Per Share
Consideration” means (i) if the consideration paid to holders of the Ordinary Shares consists exclusively of cash, the
amount of such cash per Ordinary Share, and (ii) in all other cases, the average last reported sale price of the Ordinary Shares
as reported during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event.
If any reclassification or reorganization also results in a change in Ordinary Shares covered by subsection 4.1.1 hereof, then
such adjustment shall be made pursuant to subsection 4.1.1 or Sections 4.2, or 4.3 hereof and this Section 4.4.
The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations,
sales or other transfers. In no event will the Warrant Price be reduced to less than the par value per share issuable upon exercise of
the Warrant.


 






    8


     


    

 


4.5           Notices
of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of Ordinary 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 Ordinary 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; provided, however, that no adjustment
to the number of Ordinary Shares issuable upon exercise of a Warrant shall be required until cumulative adjustments amount to one percent
(1%) or more of the number of Ordinary Shares issuable upon exercise of a Warrant as last adjusted; provided, further, that any such
adjustments that are not made are carried forward and taken into account in any subsequent adjustment. Notwithstanding the foregoing,
all such carried forward adjustments shall be made (i) in connection with any subsequent adjustment that (taken together with such
carried forward adjustments) would result in a change of at least one percent (1%) in the number of Ordinary Shares issuable upon exercise
of a Warrant and (ii) on the exercise date of any Warrant. Upon the occurrence of any event specified in Sections 4.1, 4.2,
4.3 or 4.4 hereof, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at
the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event. Failure to
give such notice, or any defect therein, shall not affect the legality or validity of such event.


 


4.6           No
Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue a fractional
Ordinary Share 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.


 


4.7           Form of
Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued
after such adjustment may state the same Warrant Price and the same number of Ordinary 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           Transferability.
Subject to compliance with applicable law, the Warrants may be transferred, assigned or sold to any person.


 






    9


     


    

 


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


 


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


 


5.4           Transfers
of Fractions of Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange of Warrants
which would require the issuance of a Warrant certificate or book-entry position for a fraction of a Warrant.

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


 


5.6            Warrant

of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever

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


 


6.1           No
Rights as Shareholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a shareholder of the Company,

or to receive notice as shareholder in respect of the meetings of shareholders or the election of directors of the Company or any other

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,

6.3           Reservation

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

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 and to maintain the effectiveness of such registration

the Warrant Agent and Other Matters.

shall not be obligated to pay any transfer taxes in respect of the Warrants or such Ordinary Shares.


 


7.2           Resignation,
Consolidation, or Merger of Warrant Agent.


 


7.2.1            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 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.


 






    11


     


    

 


7.2.2            Notice

7.2.3            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.

incur in the execution of its duties hereunder.

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.


 


7.4           Liability
of Warrant Agent.


 


7.4.1            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 Chairman of the Board, Chief Executive Officer, Chief Financial Officer, the President or the Secretary or
other principal officer 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.


 


7.4.2            Indemnity.
The Warrant Agent shall be liable hereunder only for its own, or its representatives’, gross negligence, willful misconduct, fraud,
bad faith or material breach of this Agreement. 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 or its representatives’ gross negligence,
willful misconduct, fraud, bad faith or material breach of this Agreement.

7.4.3            Exclusions.

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 non-assessable.


 


7.5           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.


 


7.6           Waiver.
The Warrant Agent has no right of set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any
distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of the date hereof, by
and between the Company and the Warrant Agent as trustee thereunder) and hereby agrees not to seek recourse, reimbursement, payment or
satisfaction for any Claim against the Trust Account for any reason whatsoever. The Warrant Agent hereby waives any and all Claims against
the Trust Account and any and all rights to seek access to the Trust Account.


 


8.             Miscellaneous
Provisions.


 


8.1           Successors.
All the covenants and provisions of this Agreement by or for the benefit of the Company or the Warrant Agent shall bind and inure to
the benefit of their respective successors and assigns.

8.3           Applicable
Law; 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. 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 of the forum provisions above, is filed in a court other than a court located
within the State of New York or the United States District Court for the Southern District of New York (a “foreign action”)
in the name of any Warrant holder, such Warrant holder shall be deemed to have consented to: (x) the personal jurisdiction of the
state and federal courts located within the State of New York or the United States District Court for the Southern District of New York
in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”), and (y) having
service of process made upon such Warrant holder in any such enforcement action by service upon such warrant holder’s counsel in
the foreign action as agent for such warrant holder.


 


8.4           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.


 


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

8.6           Counterparts;
Electronic Signatures. 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.
A signature to this Agreement transmitted electronically shall have the same authority, effect and enforceability as an original signature.


 


8.7           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.


 


8.8           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 (ii) 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. All other modifications or amendments, including any modification or amendment to increase the Warrant Price or shorten
the Exercise Period shall require the vote or written consent of the Registered Holders of fifty percent (50%) 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 hereof, respectively, without the consent of the Registered Holders.


 


8.9           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) evidenced hereby
(the “Warrants” and each, a “Warrant”) to purchase Class A ordinary shares, $0.0001
par value per share (“Ordinary Shares”), of Spring Valley Acquisition Corp. II, a Cayman Islands exempted company
(the “Company”). Each whole Warrant entitles the holder, upon exercise during the period set forth in the Warrant
Agreement referred to below, to receive from the Company that number of fully paid and non-assessable Ordinary Shares as set forth below,
at the exercise price (the “Warrant Price”) as determined pursuant to the Warrant Agreement, payable in lawful
money of the United States of America upon surrender of this Warrant Certificate and payment of the Warrant Price (or through “cashless
exercise” as provided for in the Warrant Agreement) 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. No fractional shares will be issued upon exercise of any Warrant. If, upon the exercise
of Warrants, a holder would be entitled to receive a fractional interest in an Ordinary Share, the Company will, upon exercise, round
down to the nearest whole number of the number of Ordinary Shares to be issued to the holder of the Warrant. 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 Warrant Price per Ordinary Share for
any Warrant is equal to $11.50 per share. The Warrant 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 null and void.


 






    B-1


     


    

 


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


 


This Warrant Certificate shall not be valid unless
countersigned by the Warrant Agent, as such term is used in the Warrant Agreement.


 


This Warrant Certificate shall be governed by and
construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles thereof.

[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 [__], 202[_] (the “Warrant Agreement”), duly executed and delivered
by the Company to Continental Stock Transfer & Trust Company, a New York limited purpose trust company, as warrant agent (or
successor warrant agent) (collectively, 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 Warrant 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 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 and the Warrant Price 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 Ordinary Shares, 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.


 






    B-3


     


    

 


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.

In the event that the Warrant is to be exercised
on a “cashless” basis pursuant to Section 7.4 of the Warrant Agreement, the number of Ordinary Shares

exercisable for would be determined in accordance with the relevant section of the Warrant Agreement which allows for such cashless exercise
and (ii) the holder hereof shall complete the following: The undersigned hereby irrevocably elects to exercise the right, represented
by this Warrant Certificate, through the cashless exercise provisions of the Warrant Agreement, to receive Ordinary Shares. If said number
of Ordinary Shares is less than all of the Ordinary Shares purchasable hereunder (after giving effect to the cashless exercise), the undersigned
