or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company and the Depositary, as applicable,
of a duly executed facsimile copy or PDF copy submitted by electronic mail (or e-mail attachment) of the Notice of Exercise in the form
annexed hereto (“Notice of Exercise”). Within the earlier of (i) two (2) Trading Days and (ii) the number
of Trading Days comprising the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise
as aforesaid, the Holder shall deliver the aggregate Exercise Price for the ADSs specified in the applicable Notice of Exercise by wire

c) Cashless
Exercise. This 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 Warrant ADSs equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

 

	 	(A) =	as applicable: (i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is (1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as defined in Rule 600(b)(68) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the option of the Holder, either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise or (z) the Bid Price of the ADS on the principal Trading Market as reported by Bloomberg L.P. as of the time of the Holder’s execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter (including until two (2) hours after the close of “regular trading hours” on a Trading Day) pursuant to Section 2(a) hereof, or (iii) the VWAP on the date of the applicable Notice of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered pursuant to Section 2(a) hereof after the close of “regular trading hours” on such Trading Day;
	 	 	 
	 	(B) =	the Exercise Price of this Warrant, as adjusted hereunder; and
	 	 	 
	 	(X) =	the number of Warrant ADSs that would be issuable upon exercise of this 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
Warrant ADSs 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 Warrant ADSs shall
take on the registered characteristics of the Warrants being exercised. The Company agrees not to take any position contrary to this Section 2(c).

 

“Bid Price”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the ADS is then listed or quoted
on a Trading Market, the bid price of the ADS for the time in question (or the nearest preceding date) on the Trading Market on which
the ADS is then listed or 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)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the ADS for
such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the ADS is not then listed or quoted for trading
on OTCQB or OTCQX and if prices for the ADS are then reported in The Pink Open Market (or a similar organization or agency succeeding
to its functions of reporting prices), the most recent bid price per ADS so reported, or (d) in all other cases, the fair market
value of an ADS as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities
then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

 

“VWAP”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the ADS is then listed or quoted
on a Trading Market, the daily volume weighted average price of the ADS for such date (or the nearest preceding date) on the Trading Market
on which the ADS is then listed or 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)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the
ADS for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the ADS is not then listed or quoted for
trading on OTCQB or OTCQX and if prices for the ADS are then reported in The Pink Open Market (or a similar organization or agency succeeding
to its functions of reporting prices), the most recent bid price per ADS so reported, or (d) in all other cases, the fair market
value of an ADS as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities
then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

 

     

     

    

 

d) Mechanics
of Exercise.

 

i. Delivery
of Warrant ADSs Upon Exercise. The Company shall cause its registrar to deposit the Warrant Shares subject to such exercise with
Depositary, and cause the Depositary to credit the account of the Holder’s or its designee’s balance account with The
Depository Trust Company (or another established clearing corporation performing similar functions) through its Deposit or
Withdrawal at Custodian system (“DWAC”) if the Depositary is then a participant in such system and either
(A) there is an effective registration statement permitting the issuance of the Warrant ADSs to or resale of the Warrant ADSs
by the Holder or (B) this Warrant is being exercised via cashless exercise, and otherwise by physical delivery of the Warrant
Shares, registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant ADSs
to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the
date that is the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard
Settlement Period after the delivery to the Company of the Notice of Exercise (such date, the “Warrant ADS Delivery
Date”) provided that the Warrant ADS Delivery Date shall not be deemed to have occurred until such time that the Company
has received the aggregate Exercise Price. Upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate
purposes to have become the holder of record of the Warrant ADSs with respect to which this Warrant has been exercised, irrespective
of the date of delivery of the Warrant ADSs. If the Company fails for any reason to deliver to the Holder the Warrant ADSs subject
to a Notice of Exercise by the Warrant ADS Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and
not as a penalty, for each $1,000 of Warrant ADSs subject to such exercise (based on the VWAP of the ADS on the date of the
applicable Notice of Exercise), $10 per Trading Day (increasing to $20 per Trading Day on the fifth Trading Day after such
liquidated damages begin to accrue) for each Trading Day after such Warrant ADS Delivery Date until such Warrant ADSs are delivered
or Holder rescinds such exercise. The Company agrees to maintain a registrar (which can be the depositary) that is a participant in
the FAST program so long as this Warrant remains outstanding and exercisable. “Standard Settlement Period” means
the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to
the ADSs as in effect on the date of delivery of the Notice of Exercise. Notwithstanding the foregoing, with respect to any
Notice(s) of Exercise delivered on or prior to 12:00 p.m. (New York City time) on the Initial Exercise Date, which may be
delivered at any time after the time of execution of the Purchase Agreement, the Company agrees to deliver the Warrant ADSs subject
to such notice(s) by 4:00 p.m. (New York City time) on the Initial Exercise Date and the Initial Exercise Date shall be
the Warrant ADS Delivery Date for purposes hereunder.

 

ii. Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and
upon surrender of this Warrant, at the time of delivery of the Warrant ADSs, deliver to the Holder a new Warrant evidencing the rights
of the Holder to exercise the unexercised Warrant ADSs called for by this Warrant, which new Warrant shall in all other respects be identical
with this Warrant.

 

iii. Rescission
Rights. If the Company fails to cause the Depositary to transmit to the Holder the Warrant ADSs pursuant to Section 2(c)(i) by
the Warrant ADS Delivery Date, then the Holder will have the right to rescind such exercise; provided, however,
that the Holder shall be required to return any Warrant ADSs or Ordinary Shares subject to any such rescinded exercise notice concurrently
and the restoration of Holder’s right to acquire such Warrant ADSs pursuant to this Warrant (including, issuance of a replacement
warrant certificate evidencing such restored right).

 

     

     

    

 

iv. Compensation
for Buy-In on Failure to Timely Deliver Warrant ADSs Upon Exercise. In addition to any other rights available to the Holder, if the
Company fails to cause the Depositary to transmit to the Holder the Warrant ADSs in accordance with the provisions of Section 2(c)(i) above
pursuant to an exercise on or before the Warrant ADS Delivery Date, and if after such date the Holder is required by its broker to purchase
(in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, ADSs to deliver in satisfaction
of a sale by the Holder of the Warrant ADSs which the Holder anticipated receiving upon such exercise (a “Buy-In”),
then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price
(including brokerage commissions, if any) for the ADSs so purchased exceeds (y) the amount obtained by multiplying (1) the number
of Warrant ADSs that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price
at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate
the portion of the Warrant and equivalent number of Warrant ADSs for which such exercise was not honored (in which case such exercise
shall be deemed rescinded) or deliver to the Holder the number of ADSs that would have been issued had the Company timely complied with
its exercise and delivery obligations hereunder. For example, if the Holder purchases ADSs having a total purchase price of $11,000 to
cover a Buy-In with respect to an attempted exercise of Warrants with an aggregate sale price giving rise to such purchase obligation
of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder
shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the
Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available
to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect
to the Company’s failure to timely deliver ADSs upon exercise of the Warrant as required pursuant to the terms hereof.

 

v. No Fractional
ADSs or Scrip. No fractional ADSs or scrip representing fractional ADSs shall be issued upon the exercise of this Warrant.

 

vi. Charges,
Taxes and Expenses. Issuance of Warrant ADSs shall be made without charge to the Holder for any issue or transfer tax or other incidental
expense in respect of the issuance of such Warrant ADSs, all of which taxes and expenses shall be paid by the Company, and such Warrant
ADSs shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however,
that in the event that Warrant ADSs are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise
shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition
thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Depositary
fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing
corporation performing similar functions) required for same-day electronic delivery of the Warrant ADSs.

 

vii. Closing
of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

 

     

     

    

 

e) Holder’s
Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise
any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise
as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting
as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would
beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number
of Ordinary Shares beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number of Ordinary Shares
held by the Holder and its Attribution Parties plus the number of Ordinary Shares underlying such Warrant ADSs issuable upon exercise
of this Warrant with respect to which such determination is being made, but shall exclude the number of Ordinary Shares underlying Warrant
ADSs which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder
or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any
other securities of the Company (including, without limitation, any other Ordinary Share Equivalents) subject to a limitation on conversion
or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties.
Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the
Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange
Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation
contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities
owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be
in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination
of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution
Parties) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company
shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status
as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder. For purposes of this Section 2(e), in determining the number of outstanding Ordinary Shares, a Holder may
rely on the number of outstanding Ordinary Shares as reflected in (A) the Company’s most recent periodic or annual report filed
with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice
by the Company or the Depositary setting forth the number of Ordinary Shares outstanding. Upon the written or oral request of a Holder,
the Company shall within one Trading Day confirm orally and in writing to the Holder the number of Ordinary Shares then outstanding. In
any case, the number of outstanding Ordinary Shares shall be determined after giving effect to the conversion or exercise of securities
of the Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number
of outstanding Ordinary Shares was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of Ordinary
Shares outstanding immediately after giving effect to the issuance of Ordinary Shares underlying the Warrant ADSs issuable upon exercise
of this Warrant. The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this
Section 2(e). Any increase in the Beneficial Ownership Limitation will not be effective until the 61st day after such notice is delivered
to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with
the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with
the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give
effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant. The Holder understands
and agrees that any increase in the Beneficial Ownership Limitation may result in such Holder becoming an affiliate of the Company and
triggering certain filing obligations with the SEC. The Company shall be responsible for payment for any such filings with the SEC; provided,
however, that the Holder shall be responsible for timely completing such filings upon triggering any such obligation.

 

     

     

    

 

Section 3. Certain
Adjustments.

 

a) Share
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a share dividend or otherwise
makes a distribution or distributions on its Ordinary Shares or ADSs or any other equity or equity equivalent securities payable in
Ordinary Shares or ADSs (which, for avoidance of doubt, shall not include any ADSs issued by the Company upon exercise of this
Warrant), as applicable, (ii) subdivides outstanding Ordinary Shares or ADSs into a larger number of shares or ADSs, as
applicable, (iii) combines (including by way of reverse share split) outstanding Ordinary Shares or ADSs into a smaller number
of shares or ADSs, as applicable, or (iv) issues by reclassification of Ordinary Shares, ADSs or any shares of capital stock of
the Company, as applicable, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be
the number of ADSs (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall
be the number of ADSs outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant
shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made
pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of
shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in
the case of a subdivision, combination or re-classification. For the purposes of clarification, the Exercise Price of this Warrant
will not be adjusted in the event that the Company or any Subsidiary thereof, as applicable, sells or grants any option to purchase,
or sell or grant any right to reprice, or otherwise dispose of or issue (or announce any offer, sale, grant or any option to
purchase or other disposition) any Ordinary Shares or Ordinary Share Equivalents, at an effective price per share less than the
Exercise Price then in effect.

 

b) Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues
or sells any Ordinary Share Equivalents or rights to purchase shares, warrants, securities or other property pro rata to the record holders
of any class of Ordinary Shares or ADSs (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms
applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number
of Ordinary Shares or ADSs acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including
without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance
or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Ordinary Shares or ADSs, as
applicable, are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the Holder’s
right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder
shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such Ordinary Shares or ADSs as
a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until
such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

 

c) Pro Rata
Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution
of its assets (or rights to acquire its assets) to holders of Ordinary Shares or ADSs, by way of return of capital or otherwise (including,
without limitation, any distribution of cash, shares or other securities, property or options by way of a dividend, spin off, reclassification,
corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance
of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the
Holder would have participated therein if the Holder had held the number of Ordinary Shares or ADSs acquirable upon complete exercise
of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation)
immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the
record holders of Ordinary Shares or ADSs, as applicable, are to be determined for the participation in such Distribution (provided, however,
to the extent that the Holder’s right to participate in any such Distribution would result in the Holder exceeding the Beneficial
Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership
of any Ordinary Shares or ADSs as a result of such Distribution to such extent) and the portion of such Distribution shall be held in
abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial
Ownership Limitation).

 

     

     

    

 

d) Fundamental
Transactions. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more
related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company (and all
of its Subsidiaries, taken as a whole), directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance
or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or
indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which
holders of ADSs are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted
by the holders of 50% or more of the outstanding ADSs, (iv) the Company, directly or indirectly, in one or more related
transactions effects any reclassification, reorganization or recapitalization of the ADSs or any compulsory share exchange pursuant
to which the ADSs is effectively converted into or exchanged for other securities, cash or property, or (v) the Company,
directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business
combination (including, without limitation, a reorganization, recapitalization, spin-off, merger or scheme of arrangement) with
another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding ADSs (not including
any ADSs held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or
party to, such stock or share purchase agreement or other business combination) (each a “Fundamental
Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each
Warrant Share underlying the Warrant ADSs that would have been issuable upon such exercise immediately prior to the occurrence of
such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the
exercise of this Warrant), the number of ADSs of the successor or acquiring corporation or of the Company, if it is the surviving
corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such
Fundamental Transaction by a holder of the number of ADSs for which this Warrant is exercisable immediately prior to such
Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise of this Warrant). If holders of
ADSs are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall
be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental
Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the
 “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other
Transaction Documents in accordance with the provisions of this Section 3(d) pursuant to written agreements in form and
substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental
Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a
corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the ADSs acquirable
and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such
Fundamental Transaction, and which required no additional consideration upon exercise, and which is reasonably satisfactory in form
and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be
substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other
Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every

of the number of Ordinary Shares (excluding treasury shares, if any) issued and outstanding.

the Commission pursuant to a Current Report on Form 6-K. The Holder shall remain entitled to exercise this Warrant during the period

herewith, may be exercised by a new holder for the purchase of Warrant ADSs without having a new Warrant issued.

Warrant except as to the number of Warrant ADSs issuable pursuant thereto.

 

     

     

    

 

c) Warrant
Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant

purposes, absent actual notice to the contrary.

 

Section 5. Miscellaneous.

 

a) Currency.
Unless otherwise indicated, all dollar amounts referred to in this Warrant are in United States Dollars (“U.S. Dollars”).

the U.S. Dollar equivalent amount in accordance with the Exchange Rate on the date of calculation. “Exchange Rate”
means, in relation to any amount of currency to be converted into U.S. Dollars pursuant to this Warrant, the U.S. Dollar exchange rate

b) No Rights
as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends or
other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set
forth in Section 3. Without limiting any rights of a Holder to receive cash payments pursuant to Section 2(d)(i), Section 2(d)(iv) and
or Section 3(d) herein, and without limiting the rights of the Holder to effect a cashless exercise or under Section 2(c) herein,
in no event shall the Company be required to net cash settle an exercise of this Warrant.

 

c) Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant ADSs, and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include
the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make
and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

 

d) Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or
granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business
Day.

 

e) Authorized
Shares.

 

The Company covenants
that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Ordinary Shares a sufficient number
of shares to provide for the issuance of the Warrant ADSs and the underlying Ordinary Shares upon the exercise of any rights under this
Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged
with the duty of issuing the necessary Warrant ADSs upon the exercise of the rights under this Warrant. The Company will take all such
reasonable action as may be necessary to assure that such Warrant ADSs and the underlying Ordinary Shares may be issued as provided herein
without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the ADS or Ordinary Shares
may be listed. The Company covenants that all Warrant ADSs and the underlying Ordinary Shares which may be issued upon the exercise of
the rights represented by this Warrant will, upon exercise of the rights represented by this Warrant, be duly authorized, validly issued,
fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other
than taxes in respect of any transfer occurring contemporaneously with such issue).

 

     

     

    

 

Except and to
the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its
certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be
necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the
generality of the foregoing, the Company will (i) not increase the par value of any Warrant ADSs above the amount payable
therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant ADSs and the underlying
Ordinary Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable
the Company to perform its obligations under this Warrant.

 

Before taking any
action which would result in an adjustment in the number of Warrant ADSs for which this Warrant is exercisable, the Company shall obtain
all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having
jurisdiction thereof.

 

f) Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by and
construed and enforced in accordance with the internal laws of the State of Delaware, without regard to the principles of conflicts of
law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions
contemplated by this Warrant (whether brought against a party hereto or their respective affiliates, directors, officers, shareholders,
partners, members, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of Dover, Delaware.
Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of Dover, Delaware
for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein,
and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject
to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding.
Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding
by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address
in effect for notices to it under this Warrant and agrees that such service shall constitute good and sufficient service of process and
notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted
by law. If either party shall commence an action, suit or proceeding to enforce any provisions of this Warrant, the prevailing party in
such action, suit or proceeding shall be reimbursed by the other party for their reasonable attorneys’ fees and other costs and
expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

 

g) Restrictions.
The Holder acknowledges that the Warrant ADSs and the underlying Ordinary Shares acquired upon the exercise of this Warrant, if not registered
and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal or foreign securities
laws.

 

h) Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as
a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this
Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results
in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and
expenses including, but not limited to, attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting
any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

 

     

     

    

 

i) Notices.
Any and all notices or other communications or deliveries to be provided by the Holders hereunder including, without limitation, any Notice
of Exercise, shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally recognized overnight courier
service, addressed to the Company, at 801 Bixing Street, Bihu County, Lishui, Zhejiang, Province, China, 323006, Attention: Dr, Chris

as the Company may specify for such purposes by notice to the Holders. Any and all notices or other communications or deliveries to be
provided by the Company hereunder shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally recognized
overnight courier service addressed to each Holder at the facsimile number, e-mail address or address of such Holder appearing on the
books of the Company. Any notice or other communication or deliveries hereunder shall be deemed given and effective on the earliest of
(i) the time of transmission, if such notice or communication is delivered via facsimile at the facsimile number or via e-mail at
the e-mail address set forth in this Section prior to 5:30 p.m. (New York City time) on any date, (ii) the next Trading
Day after the time of transmission, if such notice or communication is delivered via facsimile at the facsimile number or via e-mail at
the e-mail address set forth in this Section on a day that is not a Trading Day or later than 5:30 p.m. (New York City time)
on any Trading Day, (iii) the second Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier
service, or (iv) upon actual receipt by the party to whom such notice is required to be given. To the extent that any notice provided
hereunder constitutes, or contains, material, non-public information regarding the Company or any Subsidiaries, the Company shall simultaneously
file such notice with the Commission pursuant to a Current Report on Form 6-K.

 

j) Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to receive Warrant
ADSs, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase
price of any ADS or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

 

k) Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific
performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any
action for specific performance that a remedy at law would be adequate.

 

l) Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder.
The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable
by the Holder or holder of Warrant ADSs.

 

m) Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

 

n) Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the
extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

 

o) Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

	 	(B) =	the Exercise Price of this Warrant, as adjusted hereunder; and
	 	 	 
	 	(X) =	the number of Warrant ADSs that would be issuable upon exercise of this 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
Warrant ADSs 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 Warrant ADSs shall
take on the registered characteristics of the Warrants being exercised. The Company agrees not to take any position contrary to this Section 2(c).

on a Trading Market, the bid price of the ADS for the time in question (or the nearest preceding date) on the Trading Market on which

p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the ADS for
such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the ADS is not then listed or quoted for trading

ADS for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the ADS is not then listed or quoted for

then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

 

     

     

    

 

d) Mechanics
of Exercise.

 

i. Delivery
of Warrant ADSs Upon Exercise. The Company shall cause its registrar to deposit the Warrant Shares subject to such exercise with
Depositary, and cause the Depositary to credit the account of the Holder’s or its designee’s balance account with The
Depository Trust Company (or another established clearing corporation performing similar functions) through its Deposit or
Withdrawal at Custodian system (“DWAC”) if the Depositary is then a participant in such system and either
(A) there is an effective registration statement permitting the issuance of the Warrant ADSs to or resale of the Warrant ADSs
by the Holder or (B) this Warrant is being exercised via cashless exercise, and otherwise by physical delivery of the Warrant
Shares, registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant ADSs
to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the
date that is the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard
Settlement Period after the delivery to the Company of the Notice of Exercise (such date, the “Warrant ADS Delivery
Date”) provided that the Warrant ADS Delivery Date shall not be deemed to have occurred until such time that the Company
has received the aggregate Exercise Price. Upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate
purposes to have become the holder of record of the Warrant ADSs with respect to which this Warrant has been exercised, irrespective
of the date of delivery of the Warrant ADSs. If the Company fails for any reason to deliver to the Holder the Warrant ADSs subject
to a Notice of Exercise by the Warrant ADS Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and
not as a penalty, for each $1,000 of Warrant ADSs subject to such exercise (based on the VWAP of the ADS on the date of the
applicable Notice of Exercise), $10 per Trading Day (increasing to $20 per Trading Day on the fifth Trading Day after such
liquidated damages begin to accrue) for each Trading Day after such Warrant ADS Delivery Date until such Warrant ADSs are delivered
or Holder rescinds such exercise. The Company agrees to maintain a registrar (which can be the depositary) that is a participant in
the FAST program so long as this Warrant remains outstanding and exercisable. “Standard Settlement Period” means
the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to
the ADSs as in effect on the date of delivery of the Notice of Exercise. Notwithstanding the foregoing, with respect to any
Notice(s) of Exercise delivered on or prior to 12:00 p.m. (New York City time) on the Initial Exercise Date, which may be
delivered at any time after the time of execution of the Purchase Agreement, the Company agrees to deliver the Warrant ADSs subject
to such notice(s) by 4:00 p.m. (New York City time) on the Initial Exercise Date and the Initial Exercise Date shall be
the Warrant ADS Delivery Date for purposes hereunder.

 

ii. Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and
upon surrender of this Warrant, at the time of delivery of the Warrant ADSs, deliver to the Holder a new Warrant evidencing the rights
of the Holder to exercise the unexercised Warrant ADSs called for by this Warrant, which new Warrant shall in all other respects be identical
with this Warrant.

 

iii. Rescission
Rights. If the Company fails to cause the Depositary to transmit to the Holder the Warrant ADSs pursuant to Section 2(c)(i) by
the Warrant ADS Delivery Date, then the Holder will have the right to rescind such exercise; provided, however,
that the Holder shall be required to return any Warrant ADSs or Ordinary Shares subject to any such rescinded exercise notice concurrently
and the restoration of Holder’s right to acquire such Warrant ADSs pursuant to this Warrant (including, issuance of a replacement
warrant certificate evidencing such restored right).

 

     

     

    

 

iv. Compensation
for Buy-In on Failure to Timely Deliver Warrant ADSs Upon Exercise. In addition to any other rights available to the Holder, if the
Company fails to cause the Depositary to transmit to the Holder the Warrant ADSs in accordance with the provisions of Section 2(c)(i) above
pursuant to an exercise on or before the Warrant ADS Delivery Date, and if after such date the Holder is required by its broker to purchase
(in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, ADSs to deliver in satisfaction
of a sale by the Holder of the Warrant ADSs which the Holder anticipated receiving upon such exercise (a “Buy-In”),
then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price
(including brokerage commissions, if any) for the ADSs so purchased exceeds (y) the amount obtained by multiplying (1) the number
of Warrant ADSs that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price
at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate
the portion of the Warrant and equivalent number of Warrant ADSs for which such exercise was not honored (in which case such exercise
shall be deemed rescinded) or deliver to the Holder the number of ADSs that would have been issued had the Company timely complied with
its exercise and delivery obligations hereunder. For example, if the Holder purchases ADSs having a total purchase price of $11,000 to
cover a Buy-In with respect to an attempted exercise of Warrants with an aggregate sale price giving rise to such purchase obligation
of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder
shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the
Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available
to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect
to the Company’s failure to timely deliver ADSs upon exercise of the Warrant as required pursuant to the terms hereof.

 

v. No Fractional
ADSs or Scrip. No fractional ADSs or scrip representing fractional ADSs shall be issued upon the exercise of this Warrant.

 

vi. Charges,
Taxes and Expenses. Issuance of Warrant ADSs shall be made without charge to the Holder for any issue or transfer tax or other incidental
expense in respect of the issuance of such Warrant ADSs, all of which taxes and expenses shall be paid by the Company, and such Warrant
ADSs shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however,
that in the event that Warrant ADSs are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise
shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition
thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Depositary
fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing
corporation performing similar functions) required for same-day electronic delivery of the Warrant ADSs.

 

vii. Closing
of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

 

     

     

    

 

e) Holder’s
Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise
any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise
as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting
as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would
beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number
of Ordinary Shares beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number of Ordinary Shares
held by the Holder and its Attribution Parties plus the number of Ordinary Shares underlying such Warrant ADSs issuable upon exercise
of this Warrant with respect to which such determination is being made, but shall exclude the number of Ordinary Shares underlying Warrant
ADSs which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder
or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any
other securities of the Company (including, without limitation, any other Ordinary Share Equivalents) subject to a limitation on conversion
or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties.
Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the
Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange
Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation
contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities
owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be
in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination
of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution
Parties) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company
shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status
as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder. For purposes of this Section 2(e), in determining the number of outstanding Ordinary Shares, a Holder may
rely on the number of outstanding Ordinary Shares as reflected in (A) the Company’s most recent periodic or annual report filed
with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice
by the Company or the Depositary setting forth the number of Ordinary Shares outstanding. Upon the written or oral request of a Holder,
the Company shall within one Trading Day confirm orally and in writing to the Holder the number of Ordinary Shares then outstanding. In
any case, the number of outstanding Ordinary Shares shall be determined after giving effect to the conversion or exercise of securities
of the Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number
of outstanding Ordinary Shares was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of Ordinary
Shares outstanding immediately after giving effect to the issuance of Ordinary Shares underlying the Warrant ADSs issuable upon exercise
of this Warrant. The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this
Section 2(e). Any increase in the Beneficial Ownership Limitation will not be effective until the 61st day after such notice is delivered
to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with
the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with
the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give
effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant. The Holder understands
and agrees that any increase in the Beneficial Ownership Limitation may result in such Holder becoming an affiliate of the Company and
triggering certain filing obligations with the SEC. The Company shall be responsible for payment for any such filings with the SEC; provided,
however, that the Holder shall be responsible for timely completing such filings upon triggering any such obligation.

 

     

     

    

 

Section 3. Certain
Adjustments.

 

a) Share
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a share dividend or otherwise
makes a distribution or distributions on its Ordinary Shares or ADSs or any other equity or equity equivalent securities payable in
Ordinary Shares or ADSs (which, for avoidance of doubt, shall not include any ADSs issued by the Company upon exercise of this
Warrant), as applicable, (ii) subdivides outstanding Ordinary Shares or ADSs into a larger number of shares or ADSs, as
applicable, (iii) combines (including by way of reverse share split) outstanding Ordinary Shares or ADSs into a smaller number
of shares or ADSs, as applicable, or (iv) issues by reclassification of Ordinary Shares, ADSs or any shares of capital stock of
the Company, as applicable, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be
the number of ADSs (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall
be the number of ADSs outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant
shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made
pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of
shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in
the case of a subdivision, combination or re-classification. For the purposes of clarification, the Exercise Price of this Warrant
will not be adjusted in the event that the Company or any Subsidiary thereof, as applicable, sells or grants any option to purchase,
or sell or grant any right to reprice, or otherwise dispose of or issue (or announce any offer, sale, grant or any option to
purchase or other disposition) any Ordinary Shares or Ordinary Share Equivalents, at an effective price per share less than the
Exercise Price then in effect.

 

b) Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues
or sells any Ordinary Share Equivalents or rights to purchase shares, warrants, securities or other property pro rata to the record holders
of any class of Ordinary Shares or ADSs (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms
applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number
of Ordinary Shares or ADSs acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including
without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance
or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Ordinary Shares or ADSs, as
applicable, are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the Holder’s
right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder
shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such Ordinary Shares or ADSs as
a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until
such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

 

c) Pro Rata
Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution
of its assets (or rights to acquire its assets) to holders of Ordinary Shares or ADSs, by way of return of capital or otherwise (including,
without limitation, any distribution of cash, shares or other securities, property or options by way of a dividend, spin off, reclassification,
corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance
of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the
Holder would have participated therein if the Holder had held the number of Ordinary Shares or ADSs acquirable upon complete exercise
of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation)
immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the
record holders of Ordinary Shares or ADSs, as applicable, are to be determined for the participation in such Distribution (provided, however,
to the extent that the Holder’s right to participate in any such Distribution would result in the Holder exceeding the Beneficial
Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership
of any Ordinary Shares or ADSs as a result of such Distribution to such extent) and the portion of such Distribution shall be held in
abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial
Ownership Limitation).

 

     

     

    

 

d) Fundamental
Transactions. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more
related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company (and all
of its Subsidiaries, taken as a whole), directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance
or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or
indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which
holders of ADSs are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted
by the holders of 50% or more of the outstanding ADSs, (iv) the Company, directly or indirectly, in one or more related
transactions effects any reclassification, reorganization or recapitalization of the ADSs or any compulsory share exchange pursuant
to which the ADSs is effectively converted into or exchanged for other securities, cash or property, or (v) the Company,
directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business
combination (including, without limitation, a reorganization, recapitalization, spin-off, merger or scheme of arrangement) with
another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding ADSs (not including
any ADSs held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or
party to, such stock or share purchase agreement or other business combination) (each a “Fundamental
Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each
Warrant Share underlying the Warrant ADSs that would have been issuable upon such exercise immediately prior to the occurrence of
such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the
exercise of this Warrant), the number of ADSs of the successor or acquiring corporation or of the Company, if it is the surviving
corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such
Fundamental Transaction by a holder of the number of ADSs for which this Warrant is exercisable immediately prior to such
Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise of this Warrant). If holders of
ADSs are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall
be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental
Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the
 “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other
Transaction Documents in accordance with the provisions of this Section 3(d) pursuant to written agreements in form and
substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental
Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a
corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the ADSs acquirable
and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such
Fundamental Transaction, and which required no additional consideration upon exercise, and which is reasonably satisfactory in form
and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be
substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other
Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every
right and power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction
Documents with the same effect as if such Successor Entity had been named as the Company herein.

 

e) Change
in ADS Ratio. If after the Issuance Date the ADS ratio is increased or reduced, then the number of Warrant ADSs to be provided on
exercise of a Warrant will be reduced or increased (respectively) in inverse proportion to the change in the ADS ratio Ordinary Shares
per ADS.

 

f) Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For
purposes of this Section 3, the number of Ordinary Shares deemed to be issued and outstanding as of a given date shall be the sum
of the number of Ordinary Shares (excluding treasury shares, if any) issued and outstanding.

 

     

     

    

 

g) Notice
to Holder.

 

i. Adjustment.
Whenever this Warrant is adjusted pursuant to any provision of this Section 3, the Company shall promptly notify, in writing, the
Holder of the adjusted terms of this Warrant after such adjustment and any resulting adjustment to the number of Warrant ADSs or Warrant
Shares and setting forth a brief statement of the facts requiring such adjustment.

 

ii. Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the
Ordinary Shares, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Ordinary Shares, (C) the
Company shall authorize the granting to all holders of the Ordinary Shares rights or warrants to subscribe for or purchase any shares
of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection
with any reclassification of the Ordinary Shares, any consolidation or merger to which the Company is a party, any sale or transfer of
all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Ordinary Shares are converted into
other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding
up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile or email to the Holder at its
last facsimile number or email address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior to
the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for
the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the
holders of the Ordinary Shares of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined
or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective
or close, and the date as of which it is expected that holders of the Ordinary Shares of record shall be entitled to exchange their Ordinary
Shares for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange;
provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the
corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant constitutes, or contains,
material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with
the Commission pursuant to a Current Report on Form 6-K. The Holder shall remain entitled to exercise this Warrant during the period
commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set
forth herein.

 

Section 4. Transfer
of Warrant.

 

a) Transferability.
This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part,
upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this
Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney. Upon such surrender and, if required,
such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable,
and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing
the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the
contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant
in full, in which case, the Holder shall surrender this Warrant to the Company within ten (10) Trading Days of the date on which
the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance
herewith, may be exercised by a new holder for the purchase of Warrant ADSs without having a new Warrant issued.

 

b) New Warrants.
This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together
with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent
or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the
Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice. All Warrants issued on transfers or exchanges shall be dated the original Issue Date and shall be identical with this
Warrant except as to the number of Warrant ADSs issuable pursuant thereto.

 

     

     

    

 

c) Warrant
Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant
Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder
of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other
purposes, absent actual notice to the contrary.

 

Section 5. Miscellaneous.

 

a) Currency.
Unless otherwise indicated, all dollar amounts referred to in this Warrant are in United States Dollars (“U.S. Dollars”).
All amounts owing under this Warrant shall be paid in U.S. Dollars. All amounts denominated in other currencies shall be converted in
the U.S. Dollar equivalent amount in accordance with the Exchange Rate on the date of calculation. “Exchange Rate”
means, in relation to any amount of currency to be converted into U.S. Dollars pursuant to this Warrant, the U.S. Dollar exchange rate
as published in the Wall Street Journal (NY edition) on the relevant date of calculation.

 

b) No Rights
as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends or
other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set
forth in Section 3. Without limiting any rights of a Holder to receive cash payments pursuant to Section 2(d)(i), Section 2(d)(iv) and
or Section 3(d) herein, and without limiting the rights of the Holder to effect a cashless exercise or under Section 2(c) herein,
in no event shall the Company be required to net cash settle an exercise of this Warrant.

 

c) Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant ADSs, and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include
the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make
and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

 

d) Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or
granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business
Day.

 

e) Authorized
Shares.

 

The Company covenants
that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Ordinary Shares a sufficient number
of shares to provide for the issuance of the Warrant ADSs and the underlying Ordinary Shares upon the exercise of any rights under this
Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged
with the duty of issuing the necessary Warrant ADSs upon the exercise of the rights under this Warrant. The Company will take all such
reasonable action as may be necessary to assure that such Warrant ADSs and the underlying Ordinary Shares may be issued as provided herein
without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the ADS or Ordinary Shares
may be listed. The Company covenants that all Warrant ADSs and the underlying Ordinary Shares which may be issued upon the exercise of
the rights represented by this Warrant will, upon exercise of the rights represented by this Warrant, be duly authorized, validly issued,
fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other
than taxes in respect of any transfer occurring contemporaneously with such issue).

 

     

     

    

 

Except and to
the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its
certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be
necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the
generality of the foregoing, the Company will (i) not increase the par value of any Warrant ADSs above the amount payable
therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant ADSs and the underlying
Ordinary Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable
the Company to perform its obligations under this Warrant.

 

Before taking any
action which would result in an adjustment in the number of Warrant ADSs for which this Warrant is exercisable, the Company shall obtain
all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having
jurisdiction thereof.

 

f) Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by and
construed and enforced in accordance with the internal laws of the State of Delaware, without regard to the principles of conflicts of
law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions
contemplated by this Warrant (whether brought against a party hereto or their respective affiliates, directors, officers, shareholders,
partners, members, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of Dover, Delaware.
Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of Dover, Delaware
for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein,
and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject
to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding.
Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding
by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address
in effect for notices to it under this Warrant and agrees that such service shall constitute good and sufficient service of process and
notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted
by law. If either party shall commence an action, suit or proceeding to enforce any provisions of this Warrant, the prevailing party in
such action, suit or proceeding shall be reimbursed by the other party for their reasonable attorneys’ fees and other costs and
expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

 

g) Restrictions.
The Holder acknowledges that the Warrant ADSs and the underlying Ordinary Shares acquired upon the exercise of this Warrant, if not registered
and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal or foreign securities
laws.

 

h) Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as
a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this
Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results
in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and
expenses including, but not limited to, attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting
any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

 

     

     

    

 

i) Notices.
Any and all notices or other communications or deliveries to be provided by the Holders hereunder including, without limitation, any Notice
of Exercise, shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally recognized overnight courier
service, addressed to the Company, at 801 Bixing Street, Bihu County, Lishui, Zhejiang, Province, China, 323006, Attention: Dr, Chris
Chang Yu, email address: chris_yu@anpac.cn; telephone number: +8657820516666, or such other facsimile number, email address or address
as the Company may specify for such purposes by notice to the Holders. Any and all notices or other communications or deliveries to be
provided by the Company hereunder shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally recognized
overnight courier service addressed to each Holder at the facsimile number, e-mail address or address of such Holder appearing on the
books of the Company. Any notice or other communication or deliveries hereunder shall be deemed given and effective on the earliest of
(i) the time of transmission, if such notice or communication is delivered via facsimile at the facsimile number or via e-mail at
the e-mail address set forth in this Section prior to 5:30 p.m. (New York City time) on any date, (ii) the next Trading
Day after the time of transmission, if such notice or communication is delivered via facsimile at the facsimile number or via e-mail at
the e-mail address set forth in this Section on a day that is not a Trading Day or later than 5:30 p.m. (New York City time)
on any Trading Day, (iii) the second Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier
service, or (iv) upon actual receipt by the party to whom such notice is required to be given. To the extent that any notice provided
hereunder constitutes, or contains, material, non-public information regarding the Company or any Subsidiaries, the Company shall simultaneously
file such notice with the Commission pursuant to a Current Report on Form 6-K.

 

j) Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to receive Warrant
ADSs, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase
price of any ADS or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

 

k) Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific
performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any
action for specific performance that a remedy at law would be adequate.

 

l) Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder.
The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable
by the Holder or holder of Warrant ADSs.

 

m) Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

 

n) Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the
extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

 

o) Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.
