For the Purchase of [●] Class A Ordinary
Shares


of


Boustead Wavefront, Inc.


 


1. Purchase
Warrant. THIS CERTIFIES THAT, in consideration of funds duly paid by or on behalf of Revere Securities, LLC (“Holder”),
as registered owner of this Purchase Warrant, to Boustead Wavefront Inc., a Cayman Islands exempted company (the “Company”),
Holder is entitled, at any time or from time to time beginning [●], 2022 (the “Commencement Date”), and at or
before 5:00 p.m., Eastern time, [●], 20271
(the “Expiration Date”), but not thereafter, to subscribe for, purchase and receive, in whole or in part,
up to [●] Class A ordinary shares of the Company, par value $0.0001 per share (the “Class A shares” or “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 to close, then this Purchase Warrant may be exercised on the next succeeding day which is not such a day in accordance with the terms
herein. During the period ending on the Expiration Date, the Company agrees not to take any action that would terminate this Purchase
Warrant. This Purchase Warrant is initially exercisable at $[●]2
per Share; provided, however, that upon the occurrence of any of the events specified in Section 6 hereof, the rights granted
by this Purchase Warrant, including the exercise price per Share and the number of Shares to be received upon such exercise, shall be
adjusted as therein specified. The term “Exercise Price” shall mean the initial exercise price or the adjusted exercise
price, depending on the context.


 


2. Exercise.


 


2.1 Exercise
Form. In order to exercise this Purchase Warrant, the exercise form attached hereto must be duly executed and completed and delivered
to the Company, together with this Purchase Warrant and payment of the Exercise Price for the Shares being purchased 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. If
the subscription rights represented hereby shall not be exercised at or before 5:00 p.m., Eastern time, on the Expiration Date, this Purchase
Warrant shall become and be void without further force or effect, and all rights represented hereby shall cease and expire. Each exercise
hereof shall be irrevocable.


 


2.2 Cashless
Exercise. In lieu of exercising this Purchase Warrant by payment of cash or check payable to the order of the Company pursuant
to Section 2.1 above, this Purchase Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise”
in which the Holder shall be entitled to receive a number of Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:


 


(A) = the FMV of one Class
A share;


 


 






		1	[Shall be the five-year anniversary of the commencement date
of sales in the offering.]



		2	[100% of the public offering price.]



 






    1


     


    

 


(B) = the Exercise Price of
this Purchase Warrant, as adjusted hereunder; and


 


(X) = the number of Class
A shares underlying the Purchase Warrant that would be issuable upon exercise of this Purchase Warrant in accordance with the terms of
this Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.


 


If Shares are issued in such
a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the Shares shall
take on the registered characteristics of the Purchase Warrants being exercised. The Company agrees not to take any position contrary
to this Section 2.2.


 


Notwithstanding anything herein
to the contrary, on the Expiration Date, this Purchase Warrant shall be automatically exercised via cashless exercise pursuant to this
Section 2.2.


 


“FMV” means,
for any date, the price determined by the first of the following clauses that applies: (a) if the Class A shares are then listed or quoted
on a Trading Market, the value shall be deemed to be the highest intra-day or closing price on any trading day on such Trading Market
on which the Class A shares are then listed or quoted as reported by Bloomberg L.P. (“Bloomberg”) (based on a trading
day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)) during the five trading days preceding the exercise, (b) if
OTCQB or OTCQX is not a Trading Market, the value shall be deemed to be the highest intra-day or closing price on any trading day on the
OTCQB or OTCQX on which the Class A shares are then quoted as reported by Bloomberg L.P. (based on a trading day from 9:30 a.m. (New York
City time) to 4:02 p.m. (New York City time)) during the five trading days preceding the exercise, as applicable, (c) if the Class A shares
are not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Class A shares are then reported in the “Pink
Sheets” published by OTC Markets Group, Inc. (or a similar organization or agency succeeding to its functions of reporting prices),
the “OTC Markets Group”, the value shall be deemed to be the highest intra-day or closing price on any trading day on the
Pink Sheets on which the Class A shares are then quoted as reported by OTC Markets Group (based on a trading day from 9:30 a.m. (New York
City time) to 4:02 p.m. (New York City time)) during the five trading days preceding the exercise, or (d) in all other cases, the fair
market value of a Class A share as determined by an independent appraiser selected in good faith by the Holder and reasonably acceptable
to the Company, the fees and expenses of which shall be paid by the Company.


 


“Trading Market”
means the NASDAQ Stock Market LLC, or any of the following other markets or exchanges on which the Class A shares are listed or quoted
for trading on the date in question: the NYSE American, the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select
Market or the New York Stock Exchange (or any successors to any of the foregoing).


 


2.3  Legend.
Each certificate for the securities purchased under this Purchase Warrant shall bear a legend as follows unless such securities have been
registered under the Securities Act of 1933, as amended (the “Act”):


 


“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.”


 


3. Transfer.


 


3.1 General
Restrictions. The registered Holder of this Purchase Warrant agrees by his, her or its acceptance hereof, that such Holder will not:
(a) sell, transfer, assign, pledge or hypothecate this Purchase Warrant for a period of one hundred eighty (180) days following the Effective
Date to anyone other than: (i) Revere Securities, LLC (“Revere”) or an underwriter, placement agent, or a selected
dealer participating in the Offering, or (ii) an officer, partner, registered person or affiliate of Revere or of any such underwriter,
placement agent or selected dealer, in each case in accordance with FINRA Conduct Rule 5110(e)(1), or (b) cause this Purchase 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 Purchase Warrant or the securities hereunder, except as provided for in FINRA Rule 5110(e)(2).
After 180 days after the Effective Date, 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 duly executed
and completed, together with the Purchase Warrant and payment of all transfer taxes, if any, payable in connection therewith. The Company
shall within five (5) Business Days transfer this Purchase Warrant on the books of the Company and shall execute and deliver a new Purchase
Warrant or Purchase Warrants of like tenor to the appropriate assignee(s) expressly evidencing the right to purchase the aggregate number
of Shares purchasable hereunder or such portion of such number as shall be contemplated by any such assignment.


 






    2


     


    

 


3.2  Restrictions
Imposed by the Act. The securities evidenced by this Purchase Warrant shall not be transferred unless and until: (i) if required by
applicable law, the Company has received the opinion of counsel for the Company that the securities may be transferred pursuant to an
exemption from registration under the Act and applicable state securities laws, or (ii) a registration statement or a post-effective amendment
to the Registration Statement relating to the offer and sale of such securities has been filed by the Company and declared effective by
the U.S. Securities and Exchange Commission (the “Commission”) and compliance with applicable state securities
law has been established.


 


4. Piggyback
Registration Rights.


 


4.1 Grant
of Right. Whenever the Company proposes to register any Class A shares under the Act (other than (i) a registration effected solely
to implement an employee benefit plan or a transaction to which Rule 145 of the Act is applicable, or (ii) a registration statement on
Form S-4, S-8 or any successor form thereto or another form not available for registering the Shares issuable upon exercise of this Purchase
Warrant for sale to the public, whether for its own account or for the account of one or more stockholders of the Company (a “Piggyback
Registration”), the Company shall give prompt written notice (in any event no later than ten (10) Business Days prior to the
filing of such registration statement) to the Holder of the Company’s intention to effect such a registration and, subject to the
remaining provisions of this Section 4.1, shall include in such registration such number of Shares underlying this Purchase Warrant (the
“Registrable Securities”) that the Holders have (within ten (10) Business Days of the respective Holder’s receipt
of such notice) requested in writing (including such number) to be included within such registration. If a Piggyback Registration is an
underwritten offering and the managing underwriter advises the Company that it has determined in good faith that marketing factors require
a limit on the number of Class A shares to be included in such registration, including all Shares issuable upon exercise of this Purchase
Warrant (if the Holder has elected to include such shares in such Piggyback Registration) and all other Class A shares proposed to be
included in such underwritten offering, the Company shall include in such registration (i) first, the number of Class A shares that the
Company proposes to sell and (ii) second, the number of Class A shares, if any, requested to be included therein by selling stockholders
(including the Holder) allocated pro rata among all such persons on the basis of the number of Class A shares then owned by each such
person. If any Piggyback Registration is initiated as a primary underwritten offering on behalf of the Company, the Company shall select
the investment banking firm or firms to act as the managing underwriter or underwriters in connection with such offering. Notwithstanding
anything to the contrary, the obligations of the Company pursuant to this Section 4.1 shall terminate on the earlier of (i) the fifth
anniversary of the Effective Date and (ii) the date that Rule 144 would allow the Holder to sell its Registrable Securities during any
ninety (90) day period.


 


4.2 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 out-of-pocket 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 Revere contained
in the Underwriting Agreement between Revere and the Company, dated as of [●], 2022. 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 the Underwriting
Agreement pursuant to which Revere has agreed to indemnify the Company.


 






    3


     


    

 


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


 


4.4  Documents
Delivered to Holders. The Company shall deliver promptly to each Holder participating in the offering requesting the correspondence
and memoranda described below, 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 and underwriter
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, during normal business hours, as any such Holder shall reasonably request.


 


4.5  Underwriting
Agreement. The Holders shall be parties to any underwriting agreement relating to a Piggyback Registration. Such Holders shall not
be required to make any representations or warranties to or agreements with the Company or the underwriters except as they may relate
to such Holders, their Shares and the amount and nature of their ownership thereof and their intended methods of distribution.


 


4.6  Documents
to be Delivered by Holder(s). Each of the Holder(s) participating in any of the foregoing offerings shall furnish to the Company a
completed and executed questionnaire provided by the Company requesting information customarily sought of selling security holders.


 


4.7  Damages.
Should the Company fail to comply with such provisions, the Holder(s) shall, in addition to any other legal or other relief available
to 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 proving actual damages and without the necessity of
posting bond or other security.


 


5. New
Purchase Warrants to be Issued.


 


5.1 Partial
Exercise or Transfer. Subject to the restrictions in Section 3 hereof, this Purchase 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 Purchase 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 hereto, the Company shall cause to be delivered to the Holder without charge a new Purchase Warrant of like tenor
to this Purchase 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 Purchase 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 Purchase
Warrant and of reasonably satisfactory indemnification or the posting of a bond, determined in the sole discretion of the Company, the
Company shall execute and deliver a new Purchase Warrant of like tenor and date. Any such new Purchase 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 Securities. The Exercise Price and the number of Shares underlying the Purchase 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 Shares
is increased by a stock dividend payable in Shares or by a split up of Shares or other similar event, then, on the effective day thereof,
the number of Shares purchasable hereunder shall be increased in proportion to such increase in outstanding Shares, and the Exercise Price
shall be proportionately decreased.


 






    4


     


    

 


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


 


6.1.3  Replacement
of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding Shares other than a change
covered by Section 6.1.1 or 6.1.2 hereof or that solely affects the par value of such Shares, or in the case of any share reconstruction
or amalgamation or consolidation or merger of the Company with or into another corporation (other than a consolidation or share reconstruction
or amalgamation or merger in which the Company is the continuing corporation and that does not result in any reclassification or reorganization
of the outstanding Shares), or in the case of any sale or conveyance to another corporation or 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 Purchase Warrant shall
have the right thereafter (until the expiration of the right of exercise of this Purchase 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 Shares of the Company obtainable
upon exercise of this Purchase Warrant immediately prior to such event; and if any reclassification also results in a change in Shares
covered by Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections 6.1.1, 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 Purchase Warrant. This form of Purchase Warrant need not be changed because of any change pursuant to this Section 6.1,
and Purchase Warrants issued after such change may state the same Exercise Price and the same number of Shares as are stated in the Purchase
Warrants initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance of new Purchase Warrants reflecting
a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the Commencement Date or the
computation thereof.


 


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


 


6.3  Elimination
of Fractional Interests. The Company shall not be required to issue certificates representing fractions of Shares upon the exercise
of the Purchase 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.


 






    5


     


    

 


7.  Reservation.
The Company shall at all times reserve and keep available out of its authorized Shares, solely for the purpose of issuance upon exercise
of the Purchase Warrants, such number of Shares or other securities, properties or rights as shall be issuable upon the exercise thereof.
The Company covenants and agrees that, upon exercise of the Purchase Warrants and payment of the Exercise Price therefor, in accordance
with the terms hereby, all 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.


 


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 Purchase Warrants and their exercise, any of the events described in
Section 8.2 shall occur, then, in one or more of said events, the Company shall deliver to each Holder a copy of each notice relating
to such events given to the other shareholders of the Company at the same time and in the same manner that such notice is given to the
shareholders.


 


8.2  Events
Requiring Notice. The Company shall be required to give the notice described in this Section 8 upon one or more of the following events:

payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of retained earnings, as indicated by the
accounting treatment of such dividend or distribution on the books of the Company, or (ii) the Company shall offer to all the holders
of its 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.

6 hereof, send notice to the Holders of such event and change (“Price Notice”). The Price Notice shall describe the
event causing the change and the method of calculating same.

9.2  Headings.

9.3.  Entire
Agreement. This Purchase Warrant (together with the other agreements and documents being delivered pursuant to or in connection with
this Purchase Warrant) constitutes the entire agreement of the parties hereto with respect to the subject matter hereof, and supersedes

9.4  Binding

permitted assignees, respective successors, legal representative and assigns, and no other person shall have or be construed to have any

9.5.1 This
Purchase Warrant shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving

Company irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.


 






    7


     


    

 


9.5.2 By
the execution and delivery of this Purchase Warrant, the Company hereby irrevocably designates and appoints [●], located at [●]
as its authorized agent upon whom process may be served in any suit, proceeding or other action against it instituted by any Holder and
based upon this Purchase Warrant, or in any other action against the Company in the New York Supreme Court, County of New York or the
United States District Court for the Southern District of New York, arising out of this Purchase Warrant. The Company expressly accepts
jurisdiction of any such court in respect of any such suit, proceeding or other action and, without limiting other methods of obtaining
jurisdiction, expressly submits to nonexclusive personal jurisdiction of any such court in respect of any such suit, proceeding or other
action. Such designation and appointment shall be irrevocable, unless and until a successor authorized agent in the County and State of
New York reasonably acceptable to the Holder shall have been appointed by the Company, such successor shall have accepted such appointment
and written notice thereof shall have been given to the Holder. The Company further agrees that service of process upon its authorized
agent or successor shall be deemed in every respect personal service of process upon the Company in any such suit, proceeding or other
action. In the event that service of any process or notice of motion or other application to any such court in connection with any such
motion in connection with any such action or proceeding cannot be made in the manner described above, such service may be made in the
manner set forth in conformance with the Hague Convention on the Service Abroad of Judicial and Extrajudicial Documents on Civil and Commercial
Matters or any successor convention or treaty. The Company hereby irrevocably waives any objection that it may have or hereafter have
to the laying of venue of any such action or proceeding arising out of or based on this Purchase Warrant in any Federal or state court
sitting in the County of New York and hereby further irrevocably waives any claim that any such action or proceeding in any such court
has been brought in an inconvenient forum. The Company agrees that any final judgment after exhaustion of all appeals or the expiration
of time to appeal in any such action or proceeding arising out of this Purchase Warrant rendered by any such Federal court or state court
shall be conclusive and may be enforced in any other jurisdiction by suit on the judgment or in any other manner provided by law. Nothing
contained in this Purchase Warrant shall affect or limit the right of the Holder to serve any process or notice of motion or other application
in any other manner permitted by law or limit or affect the right of the Holder to bring any action or proceeding against the Company
or any of its properties in the courts of any other jurisdiction. The Company further agrees to take any and all action, including the
execution and filing of all such instruments and documents, as may be necessary to continue such designations and appointments or such
substitute designations and appointments in full force and effect. The Company hereby agrees with the Holder to the exclusive jurisdiction
of the New York Supreme Court, County of New York or the United States District Court for the Southern District of New York in connection
with any action or proceeding arising from this Purchase Warrant brought by the Company or the Holder. The Company (on its behalf and,
to the extent permitted by applicable law, on behalf of its stockholders and affiliates) and Holder hereby irrevocably waives, to the
fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this
Purchase Warrant or the transactions contemplated hereby.


 


9.5.3 The
Company agrees that in any suit (whether in a court in the United States or elsewhere) seeking enforcement of this Purchase Warrant or
provisions of this Purchase Warrant, if the plaintiffs therein seek a judgment in either United States dollars, the Company will not interpose
any defense or objection to or otherwise oppose judgment, if any, being awarded in such currencies. The Company agrees that it will not
initiate or seek to initiate any action, suit or proceeding, in any other jurisdiction other than in the United States, seeking damages
in respect of or for the purpose of obtaining any injunction or declaratory judgment against the enforcement of, or a declaratory judgment
concerning any alleged breach by the Company or other claim by the Holder, including without limitation any action, suit or proceeding
challenging the enforceability of or seeking to invalidate in any respect the submission by the Company hereunder to the jurisdiction
of the courts or the designation of the laws as the law applicable to this Purchase Warrant, in each case as set forth herein.


 


9.5.4 The
Company agrees that if any payment of any sum due under this Purchase Warrant from the Company is made to or received by the Holder in
a currency other than freely transferable United States dollars, whether by judicial judgment or otherwise, the obligations of the Company
under this Purchase Warrant shall be discharged only to the extent of the net amount of freely transferable United States dollars that
the Holder, in accordance with normal bank procedures, is able to lawfully purchase with such amount of such other currency. To the extent
that the Holder is not able to purchase sufficient United States dollars with such amount of such other currency to discharge the obligations
of the Company to the Holder, the obligations of the Company shall not be discharged with respect to such difference, and any such undischarged
amount will be due as a separate obligation and shall not be affected by payment of or judgment being obtained for any other sums due
under or in respect of this Purchase Warrant.


 


9.5.5 The
Company agrees that the prevailing party(ies) in any such action shall be entitled to recover from the other party(ies) all of its reasonable
attorneys’ fees and expenses relating to such action or proceeding and/or incurred in connection with the preparation therefor.
