1. Warrant.
THIS CERTIFIES THAT, pursuant to that certain Underwriting Agreement by and between China Eco-Materials Group Co. Limited, a Cayman
Islands company (the “Company”) and Network 1 Financial Securities, Inc. (“Network 1”), as
representative (the “Representative”) of the several underwriters listed in Schedule A thereto (the “Underwriters”),
dated [●], 2021 (the “Underwriting Agreement”), Network 1 (in such capacity with its permitted successors
or assigns, the “Holder”), as registered owner of this Warrant, is entitled, at any time or from time to time

not thereafter, to subscribe for, purchase and receive, in whole or in part, up to [●] ordinary shares, $0.0001 par value,
of the Company (the “Ordinary Shares”), subject to adjustment as provided in Section 6 hereof. If the
Expiration Date is a day on which banking institutions are authorized by law or executive order to close, then this Warrant may
be exercised on the next succeeding business day which is not such a day in accordance with the terms herein, provided, however,
for clarification, that banking institutions shall not be deemed to be authorized or required by law to remain closed due to “stay
at home”, “shelter-in-place”, “non-essential employee” or any other similar orders or restrictions
or the closure of any physical branch locations at the direction of any governmental authority so long as the electronic funds
transfer systems (including for wire transfers) of banking institutions in The City of New York generally are open for use by customers
on such day. During the period commencing on the date hereof and ending on the Expiration Date, the Company agrees not to take
any action that would terminate this Warrant. This Warrant is initially exercisable at $[●] per Ordinary Share (the “Exercise

2. Exercise.

 

2.1. Exercise Form.
In order to exercise this Warrant, the exercise form attached hereto as Exhibit A (the “Exercise Form”)
must be duly executed and completed and delivered to the Company, together with this Warrant and payment of the Exercise Price
for the Shares (payable in cash by wire transfer of immediately available funds to an account designated by the Company or by certified
check or official bank check to the order of the Company). If the rights represented hereby shall not be exercised at or before
5:00 p.m., Eastern time, on the Expiration Date, this Warrant shall become and be void without further force or effect, and all
rights represented hereby shall cease and expire.

 

2.2. Cashless Exercise.
In lieu of exercising this Warrant by payment of cash or check payable to the order of the Company pursuant to Section 2.1
above, Holder may elect to receive the number of Ordinary Shares equal to the value of this Warrant (or the portion thereof being
exercised), by surrender of this Warrant to the Company, together with the Exercise Form, in which event the Company shall issue
to Holder, Ordinary Shares in accordance with the following formula:

 

	 	Y (A-B)	 
	X=	________	 
	 	A	 

 

	Where,	 	X	=	The number of Ordinary Shares to be issued to Holder;
	 	 	Y	=	The number of Ordinary Shares for which the Warrant is being exercised;
	 	 	A	=	The fair market value of one Ordinary Share; and
	 	 	B	=	The Exercise Price.

 

For purposes
of this Section 2.2, the fair market value of an Ordinary Share is defined as follows:

 

(i) if the Ordinary
Shares are traded on a securities exchange, the value shall be deemed to be the average closing price of the Ordinary Shares on
such exchange for the five consecutive trading days ending on the day immediately prior to the Exercise Form being submitted in
connection with the exercise of this Warrant; or

 

(ii) if the Ordinary
Shares are actively traded over-the-counter, the value shall be deemed to be the average closing price of the Ordinary Shares for
the five consecutive trading days ending on the trading day immediately prior to the Exercise Form being submitted in connection
with the exercise of the Warrant; or

 

(iii) if there is no
active public market, the value shall be the fair market value thereof, as determined in good faith by the Company’s Board
of Directors.

 

2.3. Legend. Each
certificate for the Ordinary Shares purchased under this Warrant shall bear the following legends unless such securities have been
registered under the Securities Act of 1933, as amended (the “Act”):

 

(i) “The securities represented
by this certificate have not been registered under the Securities Act of 1933, as amended (the “Act”), or applicable
state law. Neither the securities nor any interest therein may be offered for sale, sold or otherwise transferred except pursuant
to an effective registration statement under the Act, or pursuant to an exemption from registration under the Act and applicable
state law which, in the opinion of counsel to the Company, is available”; or

 

(ii) Any legend required by the
securities laws of any state to the extent such laws are applicable to the Shares represented by a certificate, instrument, or
book entry so legended.

3.1. General Restrictions.
The registered Holder of this Warrant agrees by his, her or its acceptance hereof, that such Holder will not: (a) sell, transfer,

or selected dealer participating in the offering (the “Offering”) contemplated by the Underwriting Agreement,
or (ii) other persons set forth in FINRA Rule 5110(e)(2), each of whom shall have agreed to the restrictions contained herein,
in accordance with FINRA Rule 5110(e), or (b) cause this Warrant or the securities issuable hereunder to be the subject of any
hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of this Warrant
or the securities hereunder, except as provided for in FINRA Rule 5110(e)(2), until the end of the 180 day period beginning on
the date of commencement of sales of the Offering. On and after that date that is 180 days period beginning on the date of commencement
of sales of the Offering, transfers to others may be made subject to compliance with or exemptions from applicable securities laws.
In order to make any permitted assignment, the Holder must deliver to the Company the assignment form, attached hereto as Exhibit

therewith. The Company shall within five business days transfer this Warrant on the books of the Company and shall execute and
deliver a new Warrant or Warrants of like tenor to the appropriate assignee(s) expressly evidencing the right to purchase the aggregate
number of Ordinary Shares purchasable hereunder or such portion of such number as shall be contemplated by any such assignment.
For the avoidance of doubt, the restricted activities mentioned above do not include the rights of the registered Holder of this
Warrant to exercise this Warrant and receive the securities issuable hereunder at any time after the Issuance Date.

 

3.2. Restrictions
Imposed by the Act. The securities evidenced by this Warrant shall not be transferred unless and until: (i) the Company has
received the opinion of counsel for the Holder that the securities may be transferred pursuant to an exemption from registration
under the Act and applicable state securities laws, the availability of which is established to the reasonable satisfaction of
the Company, (ii) a registration statement relating to the offer and sale of such securities that includes a current prospectus
with respect to which the Holder has exercised its registration rights pursuant to Section 4.2 herein, has been filed and

4. Registration
Rights.

 

4.1. “Piggy-Back”
Registration.

 

4.1.1. Grant of
Right. Unless all of the Registrable Securities are included in an effective registration statement with a current prospectus
or a qualified offering statement with a current offering circular, the Holder shall have the right, for a period of five years
commencing on the date of sales of the Offering, to include the remaining Registrable Securities as part of any other registration
of securities filed by the Company (other than in connection with a transaction contemplated by Rule 145 promulgated under the
Act or pursuant to Form F-3 or any equivalent form).

 

4.1.2. Terms.
The Company shall bear all fees and expenses attendant to registering the Registrable Securities pursuant to Section 4.1.1 hereof,
but the Holders shall pay any and all underwriting commissions and the expenses of any legal counsel selected by the Holders to
represent them in connection with the sale of the Registrable Securities. In the event of such a proposed registration, the Company
shall furnish the then Holders of outstanding Registrable Securities with not less than 30 days written notice prior to the proposed
date of filing of such registration statement. Such notice to the Holders shall continue to be given for each registration statement
filed by the Company until such time as all of the Registrable Securities have been registered under an effective registration
statement. The holders of the Registrable Securities shall exercise the “piggy-back” rights provided for herein by
giving written notice, within ten days of the receipt of the Company’s notice of its intention to file a registration statement.
Except as otherwise provided in this Warrant, there shall be no limit on the number of times the Holder may request registration
under this Section 4.1.2. Notwithstanding the provisions of this Section 4.1.2, such piggyback registration rights
shall terminate on the fifth anniversary of the commencement of sales of the Offering in accordance with FINRA 5110(g)(8)(D).

 

    4

     

    

 

4.2. General Terms.

 

4.2.1. Indemnification.
The Company shall indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any registration statement hereunder
and each person, if any, who controls such Holders within the meaning of Section 15 of the Act or Section 20(a) of the Securities
Exchange Act of 1934, as amended (“Exchange Act”), against all loss, claim, damage, expense or liability (including
all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending against any
claim whatsoever) to which any of them may become subject under the Act, the Exchange Act or otherwise, arising from such registration
statement but only to the same extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify
the Underwriters contained in Section 7.1 of the Underwriting Agreement. The Holder(s) of the Registrable Securities to be sold
pursuant to such registration statement, and their successors and assigns, shall severally, and not jointly, indemnify the Company,
against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other expenses reasonably
incurred in investigating, preparing or defending against any claim whatsoever) to which they may become subject under the Act,
the Exchange Act or otherwise, arising from information furnished by or on behalf of such Holders, or their successors or assigns,
in writing, for specific inclusion in such registration statement to the same extent and with the same effect as the provisions
contained in Section 7.2 of the Underwriting Agreement pursuant to which the Underwriters have agreed to indemnify the Company.

 

4.2.2. Exercise
of Warrant. Nothing contained in this Warrant shall be construed as requiring the Holder(s) to exercise this Warrant prior
to or after the initial filing of any registration statement or the effectiveness thereof.

 

4.2.3. Documents
Delivered to Holders. If the registration statement includes an underwritten public offering of the Company, the Company shall
also deliver promptly to each Holder participating in the offering requesting the correspondence and memoranda described below
and to the managing underwriter, if any, copies of all correspondence between the Commission and the Company, its counsel or auditors
and all memoranda relating to discussions with the Commission or its staff with respect to the registration statement and permit
each Holder to do such investigation, upon reasonable advance notice, with respect to information contained in or omitted from
the registration statement as it deems reasonably necessary to comply with applicable securities laws or rules of FINRA. Such investigation
shall include access to books, records and properties and opportunities to discuss the business of the Company with its officers
and independent auditors, all to such reasonable extent and at such reasonable times as any such Holder shall reasonably request.

 

4.2.4. Underwriting
Agreement. If the registration statement for the Holders’ Registrable Securities includes an underwritten public offering
of the Company, the Company shall enter into an underwriting agreement with the managing underwriter(s), if any. Such agreement
shall be reasonably satisfactory in form and substance to the Company, each Holder and such managing underwriter, and shall contain
such representations, warranties and covenants by the Company and such other terms as are customarily contained in agreements of
that type used by the managing underwriter. The Holders shall be parties to any underwriting agreement relating to an underwritten
sale of their Registrable Securities and may, at their option, require that any or all the representations, warranties and covenants
of the Company to or for the benefit of such underwriter(s) shall also be made, when applicable to the Holders Registrable Securities,
to and for the benefit of such Holders. Such Holders shall not be required to make any representations or warranties to or agreements
with the Company or the underwriter(s) except as they may relate to such Holders, their Shares and their intended methods of distribution.

the Holder(s), be entitled to obtain specific performance or other equitable (including injunctive) relief against the threatened
breach of such provisions or the continuation of any such breach, without the necessity of posting bond or other security.

 

4.2.7. Rule 144
Registration. The provisions of this Section 4 shall be inapplicable to the extent the Registrable Securities become

the Act.

 

5. New Warrants
to be Issued.

 

5.1. Partial Exercise
or Transfer. Subject to the restrictions in Section 3 hereof, this Warrant may be exercised or assigned in whole or
in part. In the event of the exercise or assignment hereof in part only, upon surrender of this Warrant for cancellation, together
with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price and/or transfer tax if exercised
pursuant to Section 2.1 hereof, the Company shall cause to be delivered to the Holder without charge a new Warrant of like
tenor to this Warrant in the name of the Holder evidencing the right of the Holder to purchase the number of Shares purchasable
hereunder as to which this Warrant has not been exercised or assigned.

 

5.2. Lost Certificate.
Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this Warrant and of
reasonably satisfactory indemnification or the posting of a bond, the Company shall execute and deliver a new Warrant of like tenor
and date. Any such new Warrant executed and delivered as a result of such loss, theft, mutilation or destruction shall constitute
a substitute contractual obligation on the part of the Company.

 

6. Adjustments.

 

6.1. Adjustments to
Exercise Price and Number of Ordinary Shares. The Exercise Price and the number of Ordinary Shares underlying this Warrant
shall be subject to adjustment from time to time as hereinafter set forth:

 

6.1.1. Share Dividends;
Split Ups. If, after the date hereof, and subject to the provisions of Section 6.3 below, the number of outstanding
Ordinary Shares is increased by a stock dividend payable in Ordinary Shares or by a split up of Ordinary Shares or other similar
event, then, on the effective day thereof, the number of Ordinary Shares purchasable hereunder shall be increased in proportion
to such increase in outstanding Ordinary Shares, and the Exercise Price shall be proportionately decreased.

 

6.1.2. Aggregation
of Ordinary Shares. If, after the date hereof, and subject to the provisions of Section 6.3 below, the number of outstanding
Ordinary Shares is decreased by a consolidation, combination or reclassification of Ordinary Shares or other similar event, then,
on the effective date thereof, the number of Ordinary Shares purchasable hereunder shall be decreased in proportion to such decrease
in outstanding Ordinary Shares, and the Exercise Price shall be proportionately increased.

 

    6

     

    

 

6.1.3. Replacement
of Ordinary Shares upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding Ordinary
Shares other than a change covered by Section 6.1.1 or Section 6.1.2 hereof or that solely affects the par value
of such Ordinary Shares, or in the case of any share reconstruction or amalgamation or consolidation of the Company with or into
another corporate entity (other than a consolidation or share reconstruction or amalgamation in which the Company is the continuing
entity 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 corporate entity of the property of the Company as an entirety or substantially as an entirety
in connection with which the Company is dissolved, the Holder of this Warrant shall have the right thereafter (until the expiration
of the right of exercise of this Warrant) to receive upon the exercise hereof, for the same aggregate Exercise Price payable hereunder
immediately prior to such event, the kind and amount of shares of stock or other securities or property (including cash) receivable
upon such reclassification, reorganization, share reconstruction or amalgamation, or consolidation, or upon a dissolution following
any such sale or transfer, by a Holder of the number of Ordinary Shares obtainable upon exercise of this Warrant immediately prior
to such event; and if any reclassification also results in a change in Ordinary Shares covered by Section 6.1.1 or Section
6.1.2, then such adjustment shall be made pursuant to Section 6.1.1, Section 6.1.2 and this Section 6.1.3.
The provisions of this Section 6.1.3 shall similarly apply to successive reclassifications, reorganizations, share reconstructions
or amalgamations, or consolidations, sales or other transfers.

 

6.1.4. Changes in
Form of Warrant. This form of Warrant need not be changed because of any change pursuant to this Section 6.1, and any
Warrant issued after such change may state the same Exercise Price and the same number of Ordinary Shares as are stated in the
Warrant initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance of a new Warrant reflecting a
required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the date hereof or the computation
thereof.

 

6.2. Substitute Warrant.
In case of any consolidation of the Company with, or share reconstruction or amalgamation of the Company with or into, another
corporate entity (other than a consolidation or share reconstruction or amalgamation which does not result in any reclassification
or change of the outstanding Ordinary Shares), the entity formed by such consolidation or share reconstruction or amalgamation
shall execute and deliver to the Holder a substitute Warrant providing that the holder of each Warrant then outstanding or to be
outstanding shall have the right thereafter (until the stated expiration of such Warrant) to receive, upon exercise of such Warrant,
the kind and amount of shares of stock and other securities and property receivable upon such consolidation or share reconstruction
or amalgamation, by a holder of the number of Ordinary Shares of the Company for which such Warrant might have been exercised immediately
prior to such consolidation, share reconstruction or amalgamation, sale or transfer. Such substitute Warrant shall provide for
adjustments which shall be identical to the adjustments provided for in this Section 6. The above provision of this Section
6 shall similarly apply to successive consolidations or share reconstructions or amalgamations.

 

6.3. Elimination of
Fractional Interests. The Company shall not be required to issue certificates representing fractions of Ordinary Shares upon
the exercise of the Warrant, nor shall it be required to issue scrip or pay cash in lieu of any fractional interests, it being
the intent of the parties that all fractional interests shall be eliminated by rounding any fraction up or down, as the case may
be, to the nearest whole number of Shares or other securities, properties or rights.

 

7. Reservation
and Listing. The Company shall at all times reserve and keep available out of its authorized Ordinary Shares, solely for the
purpose of issuance upon exercise of this Warrant, such number of Ordinary Shares or other securities, properties or rights as
shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of this Warrant and payment of
the Exercise Price therefor, in accordance with the terms hereby, all Ordinary Shares and other securities issuable upon such exercise
shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any shareholder. As long
as this Warrant shall be outstanding, the Company shall use its best efforts to cause all Ordinary Shares issuable upon exercise
of this Warrant to be listed (subject to official notice of issuance) on all national securities exchanges (or, if applicable,
on the OTC Bulletin Board or any successor trading market) on which the Ordinary Shares issued to the public in the Offering may
then be listed and/or quoted.

 

    7

     

    

 

8. Certain
Notice Requirements.

 

8.1. Holder’s
Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent or to
receive notice as a shareholder for the election of directors or any other matter, or as having any rights whatsoever as a shareholder
of the Company. If, however, at any time prior to the expiration of the Warrant and its exercise, any of the events described in

such notice is given to the shareholders.

shall offer to all the holders of its Ordinary Shares any additional shares of capital stock of the Company or securities convertible
into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor, or (iii)
a dissolution, liquidation or winding up of the Company (other than in connection with a consolidation or share reconstruction
or amalgamation) or a sale of all or substantially all of its property, assets and business shall be proposed.

 

8.3. Notice of Change
in Exercise Price. The Company shall, promptly after an event requiring a change in the Exercise Price pursuant to Section

to pay to the order of Elliott International, L.P. and Elliott Associates, L.P., or each of their respective registered assigns or successors in interest (the “Payees”), or order, the principal sum of three hundred thousand U.S.

on the terms and conditions described below. All payments on this Note shall be made by check or wire transfer of immediately available funds or as otherwise determined by the Maker to such account as the applicable Payee may from time to time
designate by written notice in accordance with the provisions of this Note. 
 1. Principal. The principal balance of this Note shall be payable on
the earlier of: (i) December 31, 2021 and (ii) the date on which Maker consummates an initial public offering of its securities (such earlier date, the “Maturity Date”). The principal balance may be prepaid at any
time. 
 2. Drawdown Requests. Maker and Payees agree that Maker may request, from time to time, up to three hundred thousand dollars ($300,000) in
draw downs under this Note to be used for costs and expenses related to Maker’s formation and the proposed initial public offering of its securities (the “IPO”). Principal of this Note may be drawn down from time to time prior
to the Maturity Date upon request from Maker to Payees (each, a “Drawdown Request”). Each Drawdown Request must state the amount to be drawn down, and must not be an amount less than Ten Thousand Dollars ($10,000). Payees shall, on
a several and not joint basis, fund each Drawdown Request, allocated in the manner set forth on Schedule I, no later than three (3) business days after receipt of a Drawdown Request; provided, however, that the maximum amount of
drawdowns outstanding under this Note at any time may not exceed three hundred thousand dollars ($300,000). No fees, payments or other amounts shall be due to Payees in connection with, or as a result of, any Drawdown Request by Maker. 

3. Interest. No interest shall accrue on the unpaid principal balance of this Note. 

4. Application of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any sum due under this
Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note. 

5. Events of Default. The following shall constitute an event of default (“Event of Default”): 

(a) Failure to Make Required Payments. Failure by Maker to pay the principal amount due pursuant to this Note within five (5) business days of the
date specified above. 
 (b) Voluntary Bankruptcy, Etc. The commencement by Maker of a voluntary case under any applicable bankruptcy, insolvency,
reorganization, rehabilitation or other similar law, or the consent by it to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of Maker or for any substantial
part of its property, or the making by it of any assignment for the benefit of creditors, or the failure of Maker generally to pay its debts as such debts become due, or the taking of corporate action by Maker in furtherance of any of the foregoing.

 (c) Involuntary Bankruptcy, Etc. The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of Maker in an
involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of Maker or for any substantial part of its property, or
ordering the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days. 

 

 6. Remedies. 

(a) Upon the occurrence of an Event of Default specified in Section 4(a) hereof, Payees may, by written notice to Maker, declare this Note to be due
immediately and payable, whereupon the unpaid principal amount of this Note, and all other amounts payable thereunder, shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby
expressly waived, anything contained herein or in the documents evidencing the same to the contrary notwithstanding. 
 (b) Upon the occurrence of an Event
of Default specified in Sections 4(b) and 4(c), the unpaid principal balance of this Note, and all other sums payable with regard to this Note, shall automatically and immediately become due and payable, in all cases without any action on the part
of Payees. 
 7. Waivers. Maker and all endorsers and guarantors of, and sureties for, this Note waive presentment for payment, demand, notice of
dishonor, protest, and notice of protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted by Payees under the terms of this Note, and all benefits that might accrue to Maker by virtue of any present or
future laws exempting any property, real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing for any stay of execution, exemption from civil process, or
extension of time for payment; and Maker agrees that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof, on any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order
desired by Payees. 
 8. Unconditional Liability. Maker hereby waives all notices in connection with the delivery, acceptance, performance, default,
or enforcement of the payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other party, and shall not be affected in any manner by any indulgence, extension of time, renewal, waiver or
modification granted or consented to by Payees, and consents to any and all extensions of time, renewals, waivers, or modifications that may be granted by Payees with respect to the payment or other provisions of this Note, and agrees that
additional makers, endorsers, guarantors, or sureties may become parties hereto without notice to Maker or affecting Maker’s liability hereunder.

the registration statement and prospectus to be filed with the Securities and Exchange Commission in connection with the IPO, and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the trust account for
