Re:         Base
Capped Call Option Transaction

 

The
purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the call option transaction
entered into between [Dealer Name] (“Dealer”) and Innoviva, Inc. (“Counterparty”) as
of the Trade Date specified below (the “Transaction”). This letter agreement constitutes a “Confirmation”
as referred to in the ISDA Master Agreement specified below. Each party further agrees that this Confirmation together with the Agreement
evidence a complete binding agreement between Counterparty and Dealer as to the subject matter and terms of the Transaction to which
this Confirmation relates, and shall supersede all prior or contemporaneous written or oral communications with respect thereto.

 

The
definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”), as
published by the International Swaps and Derivatives Association, Inc. (“ISDA”) are incorporated into this Confirmation.
In the event of any inconsistency between the Equity Definitions and this Confirmation, this Confirmation shall govern. Certain defined
terms used herein are based on terms that are defined in the Preliminary Offering Memorandum dated March 2, 2022 (the “Offering
Memorandum”) relating to the 2.125% Convertible Senior Notes due 2028 (as originally issued by Counterparty, the “Convertible
Notes” and each USD 1,000 principal amount of Convertible Notes, a “Convertible Note”) issued by Counterparty
in an aggregate initial principal amount of USD 225,000,000 (as increased by up to an aggregate principal amount of USD 45,000,000
if and to the extent that the Initial Purchasers (as defined herein) exercise their option to purchase additional Convertible Notes pursuant
to the Purchase Agreement (as defined herein)) pursuant to an Indenture to be dated March 7, 2022 between Counterparty and The Bank
of New York Mellon Trust Company, N.A., as trustee (the “Indenture”). In the event of any inconsistency between the
terms defined in the Offering Memorandum, the Indenture and this Confirmation, this Confirmation shall govern. The parties acknowledge
that this Confirmation is entered into on the date hereof with the understanding that (i) definitions set forth in the Indenture
which are also defined herein by reference to the Indenture and (ii) sections of the Indenture that are referred to herein will
conform to the descriptions thereof in the Offering Memorandum. If any such definitions in the Indenture or any such sections of the
Indenture differ from the descriptions thereof in the Offering Memorandum, the descriptions thereof in the Offering Memorandum will govern
for purposes of this Confirmation. The parties further acknowledge that the Indenture section numbers used herein are based on the draft
of the Indenture last reviewed by Dealer as of the date of this Confirmation, and if any such section numbers are changed in the Indenture
as executed, the parties will amend this Confirmation in good faith to preserve the intent of the parties. Subject to the foregoing,
references to the Indenture herein are references to the Indenture as in effect on the date of its execution, and if the Indenture is
amended or supplemented following such date (other than any amendment or supplement (x) pursuant to Section 8.01(I) of
the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering
Memorandum or (y) pursuant to Section 5.09 of the Indenture, subject, in the case of this clause (y), to the second paragraph
under “Method of Adjustment” in Section 3), any such amendment or supplement will be disregarded for purposes of this
Confirmation (other than as provided in Section 9(i) below) unless the parties agree otherwise in writing.

 

Each
party is hereby advised, and each such party acknowledges, that the other party has engaged in, or refrained from engaging in, substantial
financial transactions and has taken other material actions in reliance upon the parties’ entry into the Transaction to which this
Confirmation relates on the terms and conditions set forth below.

 

1.            This
Confirmation evidences a complete and binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this
Confirmation relates. This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA
Master Agreement (the “Agreement”) as if Dealer and Counterparty had executed an agreement in such form on the Trade
Date (but without any Schedule except for (i) the election of the laws of the State of New York as the governing law (without reference
to choice of law doctrine) and the election of USD as the Termination Currency, (ii) in respect of Section 5(a)(vi) of
the Agreement, (a) the “Cross Default” provisions shall apply to Dealer with a “Threshold Amount” of three
percent of the shareholders’ equity of [Dealer][Dealer’s ultimate parent] as of the Trade Date, (b) the
phrase “or becoming capable at such time of being declared” shall be deleted from clause (1) and (c) the following
language shall be added to the end thereof: “Notwithstanding the foregoing, a default under subsection (2) hereof shall not
constitute an Event of Default if (x) the default was caused solely by error or omission of an administrative or operational nature;
(y) funds were available to enable the party to make the payment when due; and (z) the payment is made within two Local Business
Days of such party’s receipt of written notice of its failure to pay.” and (iii) the term “Specified Indebtedness”
shall have the meaning specified in Section 14 of the Agreement, except that such term shall not include obligations in respect
of deposits received in the ordinary course of a party’s banking business).

In
the event of any inconsistency between provisions of the Agreement and this Confirmation, this Confirmation will prevail for the purpose
of the Transaction to which this Confirmation relates. The parties hereby agree that no transaction other than the Transaction to which
this Confirmation relates shall be governed by the Agreement. If there exists any ISDA Master Agreement between Dealer and Counterparty
or any confirmation or other agreement between Dealer and Counterparty pursuant to which an ISDA Master Agreement is deemed to exist
between Dealer and Counterparty, then notwithstanding anything to the contrary in such ISDA Master Agreement, such confirmation or agreement
or any other agreement to which Dealer and Counterparty are parties, and that the Transaction shall be deemed not to be a Transaction
under, or otherwise be governed by, any other existing or deemed ISDA Master Agreement between the parties hereto.

    Settlement Method for such Option shall be Cash Settlement.

    Value for such Valid Day, divided by (b) the Relevant Price on such Valid Day, divided by (ii) the number
    of Valid Days in the Settlement Averaging Period; provided that in no event shall the Net Share Settlement Amount for any
    Option exceed a number of Shares equal to the Applicable Limit for such Option divided by the Applicable Limit Price on the

    at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

		 	(i)	cash
                                            (the “Combination Settlement Cash Amount”) equal to the sum, for each
                                            Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the
                                            “Daily Combination Settlement Cash Amount”) equal to the lesser of (1) the
                                            product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus
                                            USD 1,000 and (2) the Daily Option Value for such Valid Day, divided by (B) the
                                            number of Valid Days in the Settlement Averaging Period; provided that if the calculation
                                            in clause (A) above results in zero or a negative number for any Valid Day, the Daily

                                            Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for
                                            such Valid Day (the “Daily Combination Settlement Share Amount”) equal
                                            to (A) (1) the Daily Option Value for such Valid Day minus the Daily Combination

                                            Averaging Period; provided that if the calculation in sub-clause (A)(1) above
                                            results in zero or a negative number for any Valid Day, the Daily Combination Settlement
                                            Share Amount for such Valid Day shall be deemed to be zero;

    Settlement Share Amount for such Option multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the
    Applicable Limit for such Option.

    that if the calculation contained in clause (ii) above results in a negative number, the Daily Option Value for such Valid
    Day shall be deemed to be zero. In no event will the Daily Option Value be less than zero.
	 	 	 
	 	Applicable
    Limit:	For
    any Option, an amount of cash equal to the Applicable Percentage multiplied by the excess of (i) the aggregate of (A) the
    amount of cash, if any, paid to the Holder of the related Convertible Note upon conversion of such Convertible Note and (B) the
    number of Shares, if any, delivered to the Holder of the related Convertible Note upon conversion of such Convertible Note multiplied

    [“Daily VWAP”] (each as defined in the Indenture) or other calculation the adjustment of which is contemplated by Section 5.05(G) of
    the Indenture. For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment

	 	Method
    of Adjustment:	Calculation
    Agent Adjustment, which means that, notwithstanding Section 11.2(c) of the Equity Definitions, upon any Potential Adjustment
    Event, the Calculation Agent, acting in good faith and commercially reasonably, taking into account the relevant provisions of the

    any other variable relevant to the exercise, settlement or payment for the Transaction.
	 	 	 
	 	 	Notwithstanding
    the foregoing and “Consequences of Merger Events / Tender Offers” below:

	 		(i)	if
                                            the Calculation Agent in good faith disagrees with any adjustment to the Convertible Notes
                                            that involves an exercise of discretion by Counterparty or its board of directors (including,
                                            without limitation, pursuant to Section 5.05(G) of the Indenture, Section 5.09
                                            of the Indenture or any supplemental indenture entered into thereunder or in connection with
                                            any proportional adjustment or the determination of the fair value of any securities, property,
                                            rights or other assets), then in each such case, the Calculation Agent will determine the
                                            adjustment to be made to any one or more of the Strike Price, Number of Options, Option Entitlement
                                            and any other variable relevant to the exercise, settlement or payment for the Transaction
                                            in a commercially reasonable manner, taking into account the relevant provisions of the Indenture;
                                            provided that, notwithstanding the foregoing, if any Potential Adjustment Event occurs
                                            during the Settlement Averaging Period but no adjustment was made to any Convertible Note
                                            under the Indenture because the relevant Holder (as such term is defined in the Indenture)
                                            was deemed to be a record owner of the underlying Shares on the related Conversion Date,
                                            then the Calculation Agent shall make a commercially reasonable adjustment, consistent with
                                            the methodology set forth in the Indenture, to the terms hereof in order to account for such
                                            Potential Adjustment Event;

                                            connection with any Potential Adjustment Event as a result of an event or condition set forth
                                            in Section 5.05(A)(ii) of the Indenture or Section 5.05(A)(iii) of the
                                            Indenture where, in either case, the period for determining “Y” (as such term
                                            is used in Section 5.05(A)(ii) of the Indenture) or “SP” (as such term
                                            is used in Section 5.05(A)(iii) of the Indenture), as the case may be, begins before
                                            Counterparty has publicly announced the event or condition giving rise to such Potential
                                            Adjustment Event, then the Calculation Agent shall have the right to adjust, in good faith
                                            and in a commercially reasonable manner, any variable relevant to the exercise, settlement
                                            or payment for the Transaction as appropriate to reflect reasonable costs (including, but
                                            not limited to, hedging mismatches and market losses) and expenses that would be incurred
                                            by Dealer assuming Dealer is maintaining a commercially reasonable hedge position (subject
                                            to requirements set forth under Hedging Adjustments below) as a result of such event or condition
                                            not having been publicly announced prior to the beginning of such period; and

 

	 		(iii)	if
                                            any Potential Adjustment Event is declared and (a) the event or condition giving rise
                                            to such Potential Adjustment Event is subsequently amended, modified, cancelled or abandoned,
                                            (b) the “Conversion Rate” (as defined in the Indenture) is otherwise not
                                            adjusted at the time or in the manner contemplated by the relevant Dilution Adjustment Provision
                                            based on such declaration or (c) the “Conversion Rate” (as defined in the
                                            Indenture) is adjusted as a result of such Potential Adjustment Event and subsequently re-adjusted
                                            (each of clauses (a), (b) and (c), a “Potential Adjustment Event Change”)
                                            then, in each case, the Calculation Agent shall have the right to adjust, in good faith and
                                            in a commercially reasonable manner, any variable relevant to the exercise, settlement or
                                            payment for the Transaction as appropriate to reflect the reasonable costs (including, but
                                            not limited to, hedging mismatches and market losses customary for transactions of this type)
                                            and commercially reasonable expenses that would be incurred by Dealer assuming Dealer is
                                            maintaining a commercially reasonable hedge position (subject to the requirements set forth
                                            under Hedging Adjustments below) as a result of such Potential Adjustment Event Change.

	 	Consequences
    of Merger Events/Tender Offers:	Notwithstanding
    Section 12.2 and Section 12.3 of the Equity Definitions, upon the occurrence of a Merger Event or a Tender Offer, the Calculation
    Agent shall make a corresponding adjustment in respect of any adjustment under the Indenture to any one or more of the nature of
    the Shares (in the case of a Merger Event), Strike Price, Number of Options, Option Entitlement and any other variable relevant to
    the exercise, settlement or payment for the Transaction to the extent that an analogous adjustment is required to be made pursuant
    to the Indenture in respect of such Merger Event or Tender Offer, subject to the second paragraph under “Method of Adjustment”;
    provided, however, that such adjustment shall be made without regard to any adjustment to the Conversion Rate pursuant
    to any Excluded Provision; provided further that if (x) with respect to any Merger Event or any Tender Offer, (A) the

    organized under the laws of the United States, any State thereof or the District of Columbia or (B) the Counterparty to the

    for U.S. federal income tax purposes or will not be organized under the laws of the United States, any State thereof or the District
    of Columbia then, in the case of either clause (x) or clause (y), Cancellation and Payment (Calculation Agent Determination)
    may apply at Dealer’s commercially reasonable election; provided further that, for the avoidance of doubt, adjustments
    shall be made pursuant to the provisions set forth above regardless of whether any Merger Event or Tender Offer gives rise to an
    Early Conversion

 

	 	Consequences
    of Announcement Events:	Modified
    Calculation Agent Adjustment as set forth in Section 12.3(d) of the Equity Definitions; provided that, in respect
    of an Announcement Event, (w) references to “Tender Offer” shall be replaced by references to “Announcement
    Event” and references to “Tender Offer Date” shall be replaced by references to “date of such Announcement
    Event”, (x) the word “shall” in the second line shall be replaced with “may”, (y) the phrase
    “exercise, settlement, payment or any other terms of the Transaction (including, without limitation, the spread)” shall
    be replaced with the phrase “Cap Price (provided that in no event shall the Cap Price be less than the Strike Price)”,
    and (z) for the avoidance of doubt, the Calculation Agent may determine whether the relevant Announcement Event has had an economic
    effect on the Transaction (the terms of which include, among other terms, the Strike Price and Cap Price) (and, if so, shall adjust
    the Cap Price accordingly) on one or more occasions on or after the date of the Announcement Event up to, and including, the Expiration
    Date, any Early Termination Date and/or any other date of cancellation, it being understood that any adjustment in respect of an
    Announcement Event shall take into account any earlier adjustment relating to the same Announcement Event. An Announcement Event
    shall be an “Extraordinary Event” for purposes of the Equity Definitions, to which Article 12 of the Equity Definitions
    is applicable.

 

    11

     

    

 

	 	Announcement
    Event:	(i) The
    public announcement by Issuer, any subsidiary of Issuer, any affiliate of Issuer, any agent of Issuer or any Valid Third Party Entity
    of (x) any transaction or event that is reasonably likely to be completed (as determined by the Calculation Agent taking into
    account the effect of such announcement on the market for the Shares and/or options on the Shares) and, if completed, would constitute
    a Merger Event or Tender Offer, (y) any potential acquisition or disposition by Issuer and/or its subsidiaries where the aggregate
    consideration exceeds 35% of the market capitalization of Issuer as of the date of such announcement (a “Transformative
    Transaction”) or (z) the intention to enter into a Merger Event or Tender Offer or a Transformative Transaction, (ii) the
    public announcement by Issuer of an intention to solicit or enter into, or to explore strategic alternatives or other similar undertakings
    that may include, a Merger Event or Tender Offer or a Transformative Transaction or (iii) any subsequent public announcement
    by any entity specified in clause (i) or (ii) of this sentence, as the case may be, of a change to a transaction or intention
    that is the subject of an announcement of the type described in clause (i) or (ii) of this sentence (including, without
    limitation, a new announcement, whether or not by the same party, relating to such a transaction or intention or the announcement
    of a withdrawal from, or the abandonment or discontinuation of, such a transaction or intention), as determined by the Calculation
    Agent. For the avoidance of doubt, the occurrence of an Announcement Event with respect to any transaction or intention shall not
    preclude the occurrence of a later Announcement Event with respect to such transaction or intention. For purposes of this definition
    of “Announcement Event,” (A) “Merger Event” shall mean such term as defined under Section 12.1(b) of
    the Equity Definitions (but, for the avoidance of doubt, the remainder of the definition of “Merger Event” in Section 12.1(b) of
    the Equity Definitions following the definition of “Reverse Merger” therein shall be disregarded) and (B) “Tender
    Offer” shall mean such term as defined under Section 12.1(d) of the Equity Definitions; provided that Section 12.1(d) of
    the Equity Definitions is hereby amended by replacing “10%” with “15%” in the third line thereof.
	 	 	 
	 	Valid
    Third Party Entity:	In
    respect of any transaction, any third party that has a bona fide intent to enter into or consummate such transaction (it being understood
    and agreed that in determining whether such third party has such a bona fide intent, the Calculation Agent may take into consideration
    of the effect of the relevant announcement by such third party on the Shares and/or options relating to the Shares).
	 	 	 
	 	Nationalization, Insolvency
    or Delisting:	Cancellation
    and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of
    the Equity Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not
    immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The Nasdaq Global Select Market or The Nasdaq
    Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any of the New
    York Stock Exchange, The Nasdaq Global Select Market or The Nasdaq Global Market (or their respective successors), such exchange
    or quotation system shall thereafter be deemed to be the Exchange.

	 	Change
    in Law:	Applicable;
    provided that Section 12.9(a)(ii) of the Equity Definitions is hereby amended by (i) replacing the phrase “the
    interpretation” in the third line thereof with the phrase “, or public announcement of, the formal or informal interpretation”,
    (ii) replacing the word “Shares” where it appears in clause (X) thereof with the words “Hedge Position”,
    (iii) replacing the parenthetical beginning after the word “regulation” in the second line thereof the words “(including,
    for the avoidance of doubt and without limitation, (x) any tax law or (y) adoption, effectiveness or promulgation of new
    regulations authorized or mandated by existing statute)”, and (iv) adding the words “provided that in the
    case of clause (Y) hereof and any law, regulation or interpretation is applied consistently by Dealer to all of its similarly
    situated counterparties and/or similar transactions;” after the semi-colon in the last line thereof.

                                            the Equity Definitions is hereby amended by (a) inserting the following words at the
                                            end of clause (A) thereof: “in the manner contemplated by the Hedging Party on
                                            the Trade Date” and (b) inserting the following two phrases at the end of such
                                            Section:

 

	 		 	“For
                                            the avoidance of doubt, the term “equity price risk” shall be deemed to include,
                                            but shall not be limited to, stock price and volatility risk. And, for the further avoidance
                                            of doubt, any such transactions or assets referred to in phrases (A) or (B) above
                                            must be available on commercially reasonable pricing terms.”; and

  

	 		(ii)	Section 12.9(b)(iii) of
                                            the Equity Definitions is hereby amended by inserting in the third line thereof, after the
                                            words “to terminate the Transaction”, the words “or, if a portion of the
                                            Transaction is affected by such Hedging Disruption (as commercially reasonably determined
                                            by the Hedging Party), such portion of the Transaction affected by such Hedging Disruption”.

 

	 	Increased

	 	Hedging
    Party:	For
    all applicable Additional Disruption Events, Dealer.

                                            with respect to which Dealer is the sole Defaulting Party, if the Calculation Agent fails

and Warranties of Counterparty.

 

Each
of the representations and warranties of Counterparty set forth in Section 1 of the Purchase Agreement (the “Purchase Agreement”)
dated as of March 2, 2022, between Counterparty and Goldman Sachs & Co. LLC and Moelis & Company LLC (the “Initial
Purchasers”), are true and correct and are hereby deemed to be repeated to Dealer as if set forth herein. Counterparty hereby
further represents and warrants to Dealer on the date hereof and on and as of the Premium Payment Date that:

 

		(a)	Counterparty
                                            has all necessary corporate power and authority to execute, deliver and perform its obligations
                                            in respect of the Transaction; such execution, delivery and performance have been duly authorized
                                            by all necessary corporate action on Counterparty’s part; and this Confirmation has
                                            been duly and validly executed and delivered by Counterparty and constitutes its valid and
                                            binding obligation, enforceable against Counterparty in accordance with its terms, subject
                                            to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
                                            similar laws affecting creditors’ rights and remedies generally, and subject, as to
                                            enforceability, to general principles of equity, including principles of commercial reasonableness,
                                            good faith and fair dealing (regardless of whether enforcement is sought in a proceeding
                                            at law or in equity) and except that rights to indemnification and contribution hereunder
                                            may be limited by federal or state securities laws or public policy relating thereto.

 

		(b)	Neither
                                            the execution and delivery of this Confirmation nor the incurrence or performance of obligations
                                            of Counterparty hereunder will conflict with or result in a breach of the certificate of
                                            incorporation or by-laws (or any equivalent documents) of Counterparty, or any applicable
                                            law or regulation, or any order, writ, injunction or decree of any court or governmental
                                            authority or agency, or any material agreement or instrument to which Counterparty or any
                                            of its subsidiaries is a party or by which Counterparty or any of its subsidiaries is bound
                                            or to which Counterparty or any of its subsidiaries is subject, or constitute a default under,

                                            law, rule, regulation or regulatory order applicable to the Shares would give rise to any
                                            reporting, consent, registration or other requirement (including without limitation a requirement
                                            to obtain prior approval from any person or entity) as a result of Dealer or its affiliates

                                            (B) will exercise independent judgment in evaluating the recommendations of any broker-dealer

                                                               this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any commercially

                                                               failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify

                                                               hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all
                                                               liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person.
                                                               Counterparty shall not be liable for any losses, claims, damages or liabilities (or expenses thereto) of any Indemnified Person that
                                                               result from the bad faith, gross negligence, willful misconduct or fraud of such Indemnified Person. If the indemnification provided
                                                               for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or
                                                               liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall
                                                               contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The
                                                               remedies provided for in this paragraph (b) are not exclusive and shall not limit any rights or remedies which may otherwise be
                                                               available to any Indemnified Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall
                                                               remain operative and in full force and effect regardless of the termination of the Transaction.

 

 

1  To
be modified for Dealers as appropriate.

2
Insert the number of Shares outstanding that would cause the current position in the Shares underlying the Transaction of
the Dealer with the highest Applicable Percentage (including the number of Shares underlying any additional transaction if the greenshoe
is exercised in full, and any Shares under pre-existing call option transactions with Counterparty) to increase by 0.5%.

3
Insert the number of Shares that, if repurchased, would cause the current position in the Shares underlying the Transaction
of the Dealer with the highest Applicable Percentage (including the number of Shares underlying any additional transaction if the greenshoe
is exercised in full, and any Shares under pre-existing call option transactions with Counterparty) to increase by a further 0.5% from
the threshold for the first Repurchase Notice.

 

    17 

     

    

 

		(c)	Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term
is used in Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), of any securities
of Counterparty, other than a distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of
Regulation M. Counterparty shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any such
distribution.

 

    18 

     

    

 

		(d)	No Manipulation. Counterparty is not entering into the Transaction to create actual or apparent
trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate
the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act.

 

		(e)	Transfer or Assignment.

 

		(i)	Counterparty shall have the right to transfer or assign its rights and obligations hereunder with respect
to all, but not less than all, of the Options hereunder (such Options, the “Transfer Options”); provided that
such transfer or assignment shall be subject to reasonable conditions that Dealer may impose, including but not limited, to the following
conditions:

 

		(A)	With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification
obligations pursuant to Section ‎9(a) or any obligations under Section ‎9(n) or ‎9(s) of this Confirmation;

 

		(B)	Any Transfer Options shall only be transferred or assigned to a third party that is a United States person
(as defined in the Internal Revenue Code of 1986, as amended);

 

		(C)	Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such
third party (including, but not limited to, an undertaking with respect to compliance with applicable securities laws in a manner that,
in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable securities laws) and execution of any
documentation and delivery of legal opinions with respect to securities laws and other matters by such third party and Counterparty, as
are requested and reasonably satisfactory to Dealer;

 

		(D)	Under the applicable law effective on or of the date of such transfer and assignment, (1) Dealer
will not, as a result of such transfer and assignment, be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of
the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment
and (2) Dealer will not, as a result of such transfer and assignment, receive from the transferee on any payment date an amount under
Section 2(d)(i)(4) of the Agreement that is less than the amount that Dealer would have received from Counterparty in the absence
of such transfer and assignment;

 

		(E)	An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such
transfer and assignment;

 

		(F)	Without limiting the generality of clause (B), Counterparty shall cause the transferee to make such Payee
Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that
results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and

 

		(G)	Counterparty shall be responsible for all reasonable costs and expenses, including reasonable counsel
fees, incurred by Dealer in connection with such transfer or assignment.

 

		(ii)	Dealer may transfer or assign (a “Transfer”) all or any part of its rights or obligations
under the Transaction (A) without Counterparty’s consent, to any affiliate of Dealer (1) that has a long-term issuer rating
that is equal to or better than Dealer’s credit rating at the time of such transfer or assignment, or (2) whose obligations
hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions,
by Dealer or Dealer’s ultimate parent, or (B) with Counterparty’s consent (not to be unreasonably withheld), to any person,
or any person whose obligations would be guaranteed by a person, in either case, with a long-term issuer rating equal to or better than
the greater of (1) the credit rating of Dealer at the time of the transfer and (2) A- by Standard and Poor’s Rating Group, Inc.
or its successor (“S&P”), or A3 by Moody’s Investor Service, Inc. (“Moody’s”)
or, if either S&P or Moody’s ceases to rate such debt, at least an equivalent rating or better by a substitute rating agency
mutually agreed by Counterparty and Dealer; provided that, in the case of any Transfer (I) an Event of Default, Potential
Event of Default or Termination Event will not occur as a result of such Transfer; (II) at the time of such Transfer either (i) each
of Dealer and the transferee in any such Transfer is a “dealer in securities” within the meaning of Section 475(c)(1) of
the Revenue Code or (ii) the Transfer does not result in a deemed exchange by Counterparty within the meaning of Section 1001
of the Revenue Code; and (III) after any such Transfer (a) Counterparty will not, as a result of any withholding or deduction
made by the transferee or assignee as a result of any Tax, receive from the transferee or assignee on any payment date or delivery date
(after accounting for amounts paid by the transferee or assignee under Section 2(d)(i)(4) of the Agreement as well as such withholding
or deduction) an amount or a number of Shares, as applicable, lower than the amount or the number of Shares, as applicable, that Dealer
would have been required to pay or deliver to Counterparty in the absence of such Transfer (except to the extent such lower amount or
number results from a change in law after the date of such Transfer), and (b) Dealer shall cause the transferee or assignee to make
such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Counterparty to permit Counterparty
to make any necessary determinations pursuant to clause (III)(a) of this proviso; provided further that Dealer shall promptly provide
written notice to Counterparty following such Transfer. If at any time at which (A) the Section 16 Percentage exceeds 7.5%,
(B) the Option Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies)
(any such condition described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer is unable after
using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party on pricing terms reasonably acceptable
to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate
any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”),
such that following such partial termination no Excess Ownership Position exists. In the event that Dealer so designates an Early Termination
Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an
Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options
equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such
partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions
of Section ‎9(l) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty
was not the Affected Party). The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage,
(A) the numerator of which is the number of Shares that Dealer and any of its affiliates or any other person subject to aggregation
with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group”
(within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within
the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent
calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher
number) and (B) the denominator of which is the number of Shares outstanding on such day. The “Option Equity Percentage”
as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number
of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by
Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “Share Amount”
as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer
or any such person, a “Dealer Person”) under any law, rule, regulation, regulatory order or organizational documents
or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”),
owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership
under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “Applicable Share Limit”
means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations
(except for any filings of Form 13F, Schedule 13D or Schedule 13G under the Exchange Act as in effect on the Trade Date) or other
requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could result in an adverse effect on
a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the
number of Shares outstanding.

 

    19 

     

    

 

		(iii)	Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer
to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Counterparty,
Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or to make or receive
such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume
such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

 

		(f)	Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory
requirements, including any requirements relating to Dealer’s commercially reasonable hedging activities hereunder, Dealer reasonably
determines that it would not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered
by Dealer on any Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date (a “Nominal
Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”)
as follows:

 

		(i)	in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (the first
of which will be on or prior to such Nominal Settlement Date and the last of which will be no later than the twentieth (20th)
Exchange Business Day following such Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement
Date;

 

		(ii)	the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered
Settlement Dates will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date; and

 

		(iii)	if the Net Share Settlement terms or the Combination Settlement terms set forth above were to apply on
the Nominal Settlement Date, then the Net Share Settlement terms or the Combination Settlement terms, as the case may be, will apply on
each Staggered Settlement Date, except that the Shares otherwise deliverable on such Nominal Settlement Date will be allocated among such
Staggered Settlement Dates as specified by Dealer in the notice referred to in clause (i) above.

 

		(g)	Dividends. If at any time during the period from and including the Effective Date, to and
including the last Expiration Date, an ex-dividend date for a cash dividend occurs with respect to the Shares, then the Calculation Agent
will adjust the Cap Price to preserve the fair value of the Transaction to Dealer after taking into account such dividend or lack thereof.

 

		(h)	Additional Termination Events.

 

		(i)	Notwithstanding anything to the contrary in this Confirmation, upon any Early Conversion in respect of
which a Notice of Conversion that is effective as to Counterparty has been delivered by the relevant converting Holder:

 

		(A)	Counterparty shall, within five Scheduled Trading Days of the Conversion Date for such Early Conversion,
provide written notice (an “Early Conversion Notice”) to Dealer specifying the number of Convertible Notes surrendered
for conversion on such Conversion Date (such Convertible Notes, the “Affected Convertible Notes”), and the giving of
such Early Conversion Notice shall constitute an Additional Termination Event as provided in this clause (i);

 

    20 

     

    

 

		(B)	upon receipt of any such Early Conversion Notice, within a commercially reasonable period of time thereafter,
Dealer shall designate an Exchange Business Day as an Early Termination Date (which Exchange Business Day shall be on or as promptly as
reasonably practicable after the Conversion Date for such Early Conversion) with respect to the portion of the Transaction corresponding
to a number of Options (the “Affected Number of Options”) equal to the lesser of (x) the number of Affected Convertible
Notes and (y) the Number of Options as of the Conversion Date for such Early Conversion;

 

		(C)	any payment hereunder with respect to such termination shall be calculated pursuant to Section 6
of the Agreement as if (x) an Early Termination Date had been designated in respect of a Transaction having terms identical to the
Transaction and a Number of Options equal to the Affected Number of Options, (y) Counterparty were the sole Affected Party with respect
to such Additional Termination Event and (z) the terminated portion of the Transaction were the sole Affected Transaction; provided
that the amount payable with respect to such termination shall not be greater than (1) the Applicable Percentage, multiplied by
(2) the Affected Number of Options, multiplied by (3) (x) the sum of (i) the amount of cash paid (if any)
to the [Holder] (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible
Note and (ii) the number of Shares delivered (if any) to the [Holder] (as such term is defined in the Indenture) of an Affected Convertible
Note upon conversion of such Affected Convertible Note, multiplied by the Applicable Limit Price, minus (y) USD 1,000;

 

		(D)	for the avoidance of doubt, in determining the amount payable in respect of such Affected Transaction
pursuant to Section 6 of the Agreement, the Calculation Agent shall assume that (x) the relevant Early Conversion and any conversions,
adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, (y) no
adjustments to the Conversion Rate have occurred pursuant to any Excluded Provision and (z) the corresponding Convertible Notes remain
outstanding; and

 

		(E)	the Transaction shall remain in full force and effect, except that, as of the Conversion Date for such
Early Conversion, the Number of Options shall be reduced by the Affected Number of Options.

 

		(ii)	Notwithstanding anything to
the contrary in this Confirmation if an event of default with respect to Counterparty occurs under the terms of the Convertible Notes
as set forth in Section 7.01 of the Indenture that results in the Convertible Notes becoming or being declared due and payable pursuant
to the terms of the Indenture, then such acceleration shall constitute an Additional Termination Event applicable to the Transaction and,
with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction
shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant
to Section 6(b) of the Agreement.

 

		(iii)	Within seven Scheduled Trading Days following any Repayment Event (as defined below), Counterparty shall
notify Dealer of such Repayment Event and the aggregate principal amount of Convertible Notes subject to such Repayment Event (any such
notice, a “Repayment Notice. Such Repurchase Notice shall contain the representation and warranty that Counterparty is not,
on the date thereof, in possession of any material non-public information with respect to Counterparty or the Shares. The receipt by Dealer
from Counterparty of any Repayment Notice shall constitute an Additional Termination Event as provided in this Section 9(h)(iii).
Upon receipt of any such Repayment Notice, within a commercially reasonable period of time thereafter, Dealer shall designate an Exchange
Business Day following receipt of such Repayment Notice as an Early Termination Date (which Exchange Business Day shall be on or as promptly
as reasonably practicable after the settlement date of the relevant Repayment Event) with respect to the portion of the Transaction corresponding
to a number of Options (the “Repayment Options”) equal to the lesser of (A) (x) the aggregate principal amount
of such Convertible Notes specified in such Repayment Notice, divided by USD 1,000, and (B) the Number of Options as of the
date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Repayment
Options. Any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if
(1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number
of Options equal to the number of Repayment Options, (2) Counterparty were the sole Affected Party with respect to such Additional
Termination Event and (3) the terminated portion of the Transaction were the sole Affected Transaction; provided that, in
the event of a Repayment Event pursuant to Section 4.02 of the Indenture or Section 4.03 of the Indenture, the amount payable
with respect to such termination shall not be greater than (x) the number of Repayment Options multiplied by (y) the
product of (A) the Applicable Percentage and (B) the excess of (I) the amount paid by the Counterparty per Convertible
Note pursuant to the relevant sections of the Indenture over (II) USD 1,000. “Repayment Event” means that (i) any
Convertible Notes are repurchased (whether in connection with or as a result of a fundamental change, howsoever defined, or for any other
reason) by Counterparty or any of its subsidiaries, (ii) any Convertible Notes are delivered to Counterparty or any of its subsidiaries
in exchange for delivery of any property or assets of such party (howsoever described), (iii) any principal of any of the Convertible
Notes is repaid prior to the final maturity date of the Convertible Notes (for any reason other than as a result of an acceleration of
the Convertible Notes that results in an Additional Termination Event pursuant to Section 9(h)(ii)), or (iv) any Convertible
Notes are exchanged by or for the benefit of the [“Holders”] (as defined in the Indenture) thereof for any other securities
of Counterparty or any of its subsidiaries (or any other property, or any combination thereof) pursuant to any exchange offer or similar
transaction. For the avoidance of doubt, any conversion of Convertible Notes (whether into cash, Shares, “Reference Property”
(as defined in the Indenture) or any combination thereof) pursuant to the terms of the Indenture shall not constitute a Repayment Event.

 

    21 

     

    

 

		(i)	Amendment Event.
Notwithstanding anything to the contrary in this Confirmation, if an Amendment Event has occurred, the Calculation Agent shall determine
whether such occurrence has had or will have a material economic effect on the Transaction and, if so, shall, adjust the Cap Price to
preserve the fair value of the Options to Dealer (taking into account, for the avoidance of doubt, such economic effect on both the Strike
Price and Cap Price); provided that in no event shall the Cap Price be less than the Strike Price.. If the Calculation Agent determines
that no adjustment that it can make pursuant to the immediately preceding sentence will produce a commercially reasonable result (including
after giving effect to the proviso thereof), it shall constitute an Additional Termination Event applicable to the Transaction and, with
respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction
shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant
to Section 6(b) of the Agreement. “Amendment Event” means that Counterparty amends, modifies, supplements,
waives or obtains a waiver in respect of any term of the Indenture or the Convertible Notes governing the principal amount, coupon, maturity,
repurchase obligation of Counterparty, any term relating to conversion of the Convertible Notes (including changes to the conversion rate,
conversion rate adjustment provisions, conversion settlement dates or conversion conditions), or any term that would require consent of
the holders of not less than 100% of the principal amount of the Convertible Notes to amend (other than, in each case, any amendment or
supplement (x) pursuant to Section 8.01(I) of the Indenture that, as determined by the Calculation Agent, conforms the
Indenture to the description of Convertible Notes in the Offering Memorandum, (y) pursuant to Section 5.09 of the Indenture
or (z) pursuant to Section 8.01(J) of the Indenture that, as determined by the Calculation Agent, cures any ambiguity,
omission, defect or inconsistency in the Indenture or in the Notes in a manner that does not adversely affect any Holder in any material
respect), in each case, without the consent of Dealer.

 

    22 

     

    

 

		(j)	Amendments to Equity Definitions.

 

		(i)	Solely in respect of adjustments to the Cap Price pursuant to Section 9(x), Section 11.2(e)(vii) of
the Equity Definitions is hereby amended by deleting the words “that may have a diluting or concentrative effect on the theoretical
value of the relevant Shares” and replacing them with the words “that is the result of a corporate event involving the Issuer
or its securities that has a material economic effect on the Shares or options on the Shares; provided that such event is not based on
(a) an observable market, other than the market for the Issuer’s own stock or (b) an observable index, other than an index
calculated and measured solely by reference to Issuer’s own operations.”

 

		(ii)	Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) inserting “(1)”
immediately following the word “means” in the first line thereof and (2) inserting immediately prior to the semi-colon
at the end of subsection (B) thereof the following words: “or (2) the occurrence of any of the events specified in Section 5(a)(vii)(1) through
(9) of the ISDA Master Agreement with respect to that Issuer”.

 

		(iii)	Section 12.9(b)(i) of
the Equity Definitions is hereby amended by replacing “either party may elect” with “Dealer may elect or, if Counterparty
represents to Dealer in writing at the time of such election that (i) it is not aware of any material nonpublic information with
respect to Counterparty or the Shares and (ii) it is not making such election as part of a plan or scheme to evade compliance
with the U.S. federal securities laws, Counterparty may elect.”

 

		(iv)	Section 12.9(b)(vi) of the Equity Definitions is hereby amended by adding the phrase “, provided that
in connection with any election by the Non-Hedging Party to terminate the Transaction, it acknowledges to Dealer, as of the date of such
election, its responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of the Exchange
Act and the rules and regulations thereunder” at the end of subsection (C).

 

		(k)	No Netting or Set-off. The provisions of Section 2(c) of the Agreement shall not
apply to the Transaction. Each party waives any and all rights it may have to set-off delivery or payment obligations it owes to the other
party under the Transaction against any delivery or payment obligations owed to it by the other party under any other agreement between
the parties hereto, by operation of law or otherwise.

 

		(l)	Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events.
If (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with
respect to the Transaction or (b) the Transaction is cancelled or terminated upon the occurrence of an Extraordinary Event (except
as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to holders of Shares
consists solely of cash, (ii) an Announcement Event, Merger Event or Tender Offer that is within Counterparty’s control, or
(iii) an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected
Party other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement
or a Termination Event of the type described in Section 5(b) of the Agreement, in each case that resulted from an event or events
outside Counterparty’s control), and if Dealer would owe any amount to Counterparty pursuant to Section 6(d)(ii) of the
Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”),
then Dealer shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty
gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 5:00 p.m. (New
York City time) on the date of the Announcement Event, Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency
or Delisting), Early Termination Date or date of cancellation, as applicable, of its election that the Share Termination Alternative shall
not apply, (b) Counterparty remakes the representation set forth in Section 8(f) as of the date of such election and (c) Dealer
agrees, in its sole discretion, to such election, in which case the provisions of Section 12.7 or Section 12.9 of the Equity
Definitions, or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply.

 

    23 

     

    

 

	 	Share Termination Alternative:	 If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable
period of time after, the date when the relevant Payment Obligation would otherwise be due pursuant to Section 12.7 or 12.9 of the
Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable, in satisfaction of such Payment Obligation
in the manner reasonably requested by Counterparty free of payment.

 

	 	Share Termination Delivery Property:	 A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the
Share Termination Unit Price. The Calculation Agent shall adjust the Share Termination Delivery Property by replacing any fractional
portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate
the Share Termination Unit Price.

 

	 	Share Termination Unit Price:	The value to Dealer of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in its discretion
by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of notification of the Payment Obligation.
For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may
consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.

 

	 	Share Termination Delivery Unit:	 One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result
of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “Exchange Property”),
a unit consisting of the type and amount of such Exchange Property received by a holder of one Share (without consideration of any requirement
to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger
Event, as determined by the Calculation Agent.

 

	 	Failure to Deliver:	 Applicable

 

	 	Other applicable provisions:	 If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions
and the provisions set forth opposite the caption “Representation and Agreement” in Section 2 will be applicable, except
that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled”
and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share
Termination Settled” in relation to the Transaction means that Share Termination Alternative is applicable to the Transaction.

 

    24 

     

    

 

		(m)	Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law,
any right it may have to a trial by jury in respect of any suit, action or proceeding relating to the Transaction. Each party (i) certifies
that no representative, agent or attorney of either party has represented, expressly or otherwise, that such other party would not, in
the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other
party have been induced to enter into the Transaction, as applicable, by, among other things, the mutual waivers and certifications provided
herein.

 

		(n)	Registration. Counterparty hereby agrees that if, in the good faith reasonable judgment
of Dealer, based on the advice of counsel, the Shares (“Hedge Shares”) acquired by Dealer for the purpose of hedging
its obligations pursuant to the Transaction cannot be sold in the public market by Dealer without registration under the Securities Act,
Counterparty shall, at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make
available to Dealer an effective registration statement under the Securities Act and enter into an agreement, in form and substance satisfactory
to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering of similar size; provided, however,
that if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the results of its due diligence
investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) or clause (iii) of
this paragraph shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge Shares in a private placement,
Counterparty will use its best efforts to enter into a private placement agreement substantially similar to private placement purchase
agreements customary for private placements of equity securities of similar size, in form and substance satisfactory to Dealer (in which
case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its reasonable judgment,
to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement
of similar size), or (iii) purchase the Hedge Shares from Dealer at the then-current market price on such Exchange Business Days,
and in the amounts and at such time(s), requested by Dealer.

 

		(o)	Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction,
Counterparty and each of its employees, representatives, or other agents may disclose to any and all persons, without limitation of any
kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses)
that are provided to Counterparty relating to such tax treatment and tax structure.

 

		(p)	Right to Extend. Dealer may postpone or add, in a commercially reasonable manner in whole
or in part, any Valid Day or Valid Days during the Settlement Averaging Period or any other date of valuation, payment or delivery by
Dealer, with respect to some or all of the Options hereunder, if Dealer reasonably determines, in its discretion, based on the advice
of counsel in the case of clause (ii) below, that such action is reasonably necessary or appropriate (i) to preserve Dealer’s
commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions (but only if there is a material
decrease in liquidity relative to Dealer’s expectations on the Trade Date) or (ii) to enable Dealer to effect purchases of
Shares in connection with its commercially reasonable hedging, hedge unwind or settlement activity hereunder in a manner that would, if
Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory
requirements of organizations with jurisdiction over Dealer or its affiliates, or with related policies and procedures which would generally
be applicable to counterparties similar to Counterparty and/or transactions similar to the Transaction; provided that no such Valid
Day or other date of valuation, payment or delivery may be postponed or added more than 40 Valid Days after the original Valid Day or
other date of valuation, payment or delivery, as the case may be; provided further that any such postponement or addition may only
be in whole, and not in part, in case any event described in clause (ii) relating solely to a self-regulatory requirement applicable
to Dealer.

 

    25 

     

    

 

		(q)	Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is
not intended to convey to Dealer rights against Counterparty with respect to the Transaction that are senior to the claims of common stockholders
of Counterparty in any United States bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall
be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Counterparty of its obligations and agreements
with respect to the Transaction; provided, further that nothing herein shall limit or shall be deemed to limit Dealer’s
rights in respect of any transactions other than the Transaction.

 

		(r)	Securities Contract; Swap Agreement. The parties hereto intend for (i) the Transaction
to be a “securities contract” and a “swap agreement” as defined in the Bankruptcy Code, and the parties hereto
to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the
Bankruptcy Code, (ii) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of
any Event of Default under the Agreement with respect to the other party to constitute a “contractual right” as described
in the Bankruptcy Code, and (iii) each payment and delivery of cash, securities or other property hereunder to constitute a “margin
payment” or “settlement payment” and a “transfer” as defined in the Bankruptcy Code.

 

		(s)	Notice of Certain Other Events. Counterparty covenants and agrees that:

 

		(i)	promptly following the public announcement of the results of any election by the holders of Shares with
respect to the consideration due upon consummation of any Merger Event, Counterparty shall give Dealer written notice of the weighted
average of the types and amounts of consideration received by holders of Shares upon consummation of such Merger Event (the date of such
notification, the “Consideration Notification Date”); provided that in no event shall the Consideration Notification
Date be later than the date on which such Merger Event is consummated; and

 

		(ii)	(A) Counterparty shall give Dealer commercially reasonable advance (but in no event less than one
Exchange Business Day) written notice of the section or sections of the Indenture and, if applicable, the formula therein, pursuant to
which any adjustment will be made to the Convertible Notes in connection with any Potential Adjustment Event, Merger Event or Tender Offer
and (B) promptly following any such adjustment, Counterparty shall give Dealer written notice of the details of such adjustment.

 

		(t)	Wall Street Transparency and Accountability Act. In connection with Section 739 of
the Wall Street Transparency and Accountability Act of 2010 (“WSTAA”), the parties hereby agree that neither the enactment
of WSTAA or any regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA, shall limit or otherwise impair
either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement,
as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under
this Confirmation, the Equity Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from Change
in Law, Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position, or Illegality (as defined in the Agreement)).

 

		(u)	Agreements and Acknowledgements Regarding Hedging. Counterparty understands, acknowledges
and agrees that: (A) at any time on and prior to the Expiration Date, Dealer and its affiliates may buy or sell Shares or other securities
or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to adjust its hedge position with
respect to the Transaction; (B) Dealer and its affiliates also may be active in the market for Shares other than in connection with
hedging activities in relation to the Transaction; (C) Dealer shall make its own determination as to whether, when or in what manner
any hedging or market activities in securities of Issuer shall be conducted and shall do so in a manner that it deems appropriate to hedge
its price and market risk with respect to the Relevant Prices; and (D) any market activities of Dealer and its affiliates with respect
to Shares may affect the market price and volatility of Shares, as well as the Relevant Prices, each in a manner that may be adverse to
Counterparty.

 

    26 

     

    

 

		(v)	Early Unwind. In the event the sale of the “Initial Securities” (as defined
in the Purchase Agreement (the “Purchase Agreement”) dated as of March 2, 2022, between Counterparty and Goldman
Sachs & Co. LLC and Moelis & Company LLC, as representatives of the Initial Purchasers party thereto (the “Initial
Purchasers”)) is not consummated with the Initial Purchasers for any reason, or Counterparty fails to deliver to Dealer opinions
of counsel as required pursuant to Section 9(a), in each case by 5:00 p.m. (New York City time) on the Premium Payment Date,
or such later date as agreed upon by the parties (the Premium Payment Date or such later date the “Early Unwind Date”),
the Transaction shall automatically terminate (the “Early Unwind”), on the Early Unwind Date and (i) the Transaction
and all of the respective rights and obligations of Dealer and Counterparty under the Transaction shall be cancelled and terminated and
(ii) each party shall be released and discharged by the other party from and agrees not to make any claim against the other party
with respect to any obligations or liabilities of the other party arising out of and to be performed in connection with the Transaction
either prior to or after the Early Unwind Date. Each of Dealer and Counterparty represents and acknowledges to the other that, upon an
Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

 

		(w)	Payment by Counterparty. In the event that, following payment of the Premium, (i) an
Early Termination Date occurs or is designated with respect to the Transaction as a result of a Termination Event or an Event of Default
(other than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Counterparty
owes to Dealer an amount calculated under Section 6(e) of the Agreement, or (ii) Counterparty owes to Dealer, pursuant
to Section 12.7 or Section 12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions,
such amount shall be deemed to be zero.

 

		(x)	Other Adjustments Pursuant to the Equity Definitions. Notwithstanding anything to the contrary
in this Confirmation, solely for the purpose of adjusting the Cap Price, the terms “Potential Adjustment Event,” “Merger
Event” and “Tender Offer” shall each have the meanings assigned to such term in the Equity Definitions (as amended by
Section 9(i) above), and upon the occurrence of a Merger Date, the occurrence of a Tender Offer Date, or declaration by Counterparty
of the terms of any Potential Adjustment Event, respectively, as such terms are defined in the Equity Definitions, the Calculation Agent
shall determine whether such occurrence or declaration, as applicable, has had a material economic effect on the Transaction and, if so,
shall, adjust the Cap Price to preserve the fair value of the Options to Dealer (taking into account, for the avoidance of doubt, such
economic effect on both the Strike Price and Cap Price); provided that in no event shall the Cap Price be less than the Strike
Price.

 

		(y)	Dealer Representation. Dealer is an “eligible contract participant” (as such
term is defined in Section 1a(18) of the Commodity Exchange Act, as amended).

 

		(z)	Tax Matters.

 

		(i)	Withholding Tax Imposed on Payments to Non-U.S. Counterparties under the United States Foreign Account
Tax Compliance Provisions of the HIRE Act. “Indemnifiable Tax,” as defined in Section 14 of the Agreement,
shall not include any U.S. federal withholding tax imposed or collected pursuant to Sections 1471 through 1474 of the U.S. Internal Revenue
Code of 1986, as amended (the “Code”), any current or future regulations or official interpretations thereof, any agreement
entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted
pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code (a “FATCA
Withholding Tax”). For the avoidance of doubt, a FATCA Withholding Tax is a Tax the deduction or withholding of which is required
by applicable law for the purposes of Section 2(d) of the Agreement.

 

    27 

     

    

 

		(ii)	HIRE Act. “Indemnifiable
Tax”, as defined in Section 14 of the Agreement, shall not include any tax imposed on payments treated as dividends from sources
within the United States under Section 871(m) of the Code or any regulations issued thereunder. For the avoidance of doubt,
any such tax imposed under Section 871(m) of the Code is a Tax the deduction or withholding of which is required by applicable
law for the purposes of Section 2(d) of the Agreement.

 

		(iii)	Tax Documentation. For the purpose
of Sections 4(a)(i) and 4(a)(ii) of the Agreement, Dealer shall provide to Counterparty a valid U.S. Internal Revenue Service
Form [W-9]4, or any successor thereto, and Counterparty shall provide to Dealer a valid U.S. Internal Revenue Service
Form W-9, or any successor thereto, or if Counterparty is an entity disregarded as separate from its owner for U.S. federal income
tax purposes, Counterparty agrees to deliver or cause to be delivered a valid U.S. Internal Revenue Service Form W-9, or any successor
thereto, of such owner. In each case, such tax form shall be completed accurately and in a manner reasonably acceptable to the other
party and shall be delivered (i) on or before the date of execution of this Confirmation and (ii) promptly upon learning that
any such tax form previously provided by it has become obsolete or incorrect. Additionally, each party shall, promptly upon request by
the other party, provide such other tax forms and documents reasonably requested by the other party.

 

		(iv)	Payor Tax Representations. For the purpose of Section 3(e) of the Agreement, each party
makes the following representation: It is not required by any applicable law, as modified by the practice of any relevant governmental
revenue authority, of any Relevant Jurisdiction to make any deduction or withholding for or on account of any Tax from any payment (other
than interest under Section 9(h) of the Agreement or amounts payable hereunder that are considered to be interest for U.S. federal
income tax purposes) to be made by it to the other party under the Agreement. In making this representation, it may rely on (i) the
accuracy of any representations made by the other party pursuant to Section 9(x)(iv) of this Confirmation, (ii) the satisfaction
of the agreement contained in Section 4(a)(i) or 4(a)(iii) of the Agreement and the accuracy and effectiveness of any document
provided by the other party pursuant to Section 4(a)(i) or 4(a)(iii) of the Agreement, (iii) the satisfaction of the
agreement of the other party contained in Section 9(x)(iv)(C) of this Confirmation and (iv) the documentation provided
by Counterparty pursuant to Section 9(x)(ii) of this Confirmation, except that in no event may a Payee’s claim of material
prejudice to its legal or commercial position excuse Payee from providing a form or document under Section 4(a)(iii) of the
Agreement.

 

		(v)	Payee Tax Representations.

 

		(A)	Counterparty is (i)(x) a “U.S. person” (as that term is used in section 1.1441-4(a)(3)(ii) of
United States Treasury Regulations) for U.S. federal income tax purposes and (y) an exempt recipient under United States Treasury
Regulation Section 1.6049-4(c)(1)(ii) or (ii) disregarded as an entity separate from its owner for U.S. federal income
tax purposes. For the avoidance of doubt, if Counterparty is or becomes a disregarded entity for U.S. federal income tax purposes, as
described in clause (ii) of the preceding sentence, the representations contained in clause (i) of the preceding sentence shall
be deemed to be made in respect of such owner.

 

 

4 To be modified for Dealers as appropriate.

 

    28 

     

    

 

		(B)	[Dealer is a “U.S. person” (as that term is used in section 1.1441-4(a)(3)(ii) of United
States Treasury Regulations) for U.S. federal income tax purposes and an exempt recipient under Treasury Regulation Section 1.6049-4(c)(1)(ii).]

 

		(C)	Each party agrees to give notice of any failure of a representation made by it under this Section 9(y)(iv) to
be accurate and true promptly upon learning of such failure.

 

		(aa)	Counterparts. This Confirmation may be executed in several counterparts, each of which shall
be deemed an original but all of which together shall constitute one and the same instrument. Delivery of an executed signature page by
facsimile or electronic transmission (e.g. “pdf” or “tif”), or any electronic signature complying with the U.S.
federal ESIGN Act of 2000, Uniform Electronic Transactions Act or other applicable law, e.g., www.docusign.com, shall be effective as
delivery of a manually executed counterpart hereof.

 

		(bb)	Conduct Rules. Each of Dealer and Counterparty acknowledges and agrees to be bound by the
Conduct Rules of the Financial Industry Regulatory Authority, Inc. applicable to transactions in options, and further agrees
not to violate the position and exercise limits set forth therein.

 

		(cc)	Risk Disclosure Statement. Counterparty represents and warrants that it has received, read
and understands the OTC Options Risk Disclosure Statement and a copy of the most recent disclosure pamphlet prepared by The Options Clearing
Corporation entitled “Characteristics and Risks of Standardized Options”.

 

		(dd)	[Insert any Dealer Agency Language][Reserved].

 

		(ee)	U.S. Resolution Stay Protocol.
The parties acknowledge and agree that (i) to the extent that prior to the date hereof both parties have adhered to the 2018
ISDA U.S. Resolution Stay Protocol (the “Protocol”), the terms of the Protocol are incorporated into and form a part
of the Agreement, and for such purposes the Agreement shall be deemed a Protocol Covered Agreement, Dealer shall be deemed a Regulated
Entity and Counterparty shall be deemed an Adhering Party; (ii) to the extent that prior to the date hereof the parties have executed
a separate agreement the effect of which is to amend the qualified financial contracts between them to conform with the requirements of
the QFC Stay Rules (the “Bilateral Agreement”), the terms of the Bilateral Agreement are incorporated into and
form a part of the Agreement, and for such purposes the Agreement shall be deemed a Covered Agreement, Dealer shall be deemed a Covered
Entity and Counterparty shall be deemed a Counterparty Entity; or (iii) if clause (i) and clause (ii) do not apply, the
terms of Section 1 and Section 2 and the related defined terms (together, the “Bilateral Terms”) of the form
of bilateral template entitled “Full-Length Omnibus (for use between U.S. G-SIBs and Corporate Groups)” published by ISDA
on November 2, 2018 (currently available on the 2018 ISDA U.S. Resolution Stay Protocol page at www.isda.org and, a copy of
which is available upon request), the effect of which is to amend the qualified financial contracts between the parties thereto to conform
with the requirements of the QFC Stay Rules, are hereby incorporated into and form a part of the Agreement, and for such purposes the
Agreement shall be deemed a “Covered Agreement,” Dealer shall be deemed a “Covered Entity” and Counterparty shall
be deemed a “Counterparty Entity.” In the event that, after the date of the Agreement, both parties hereto become adhering
parties to the Protocol, the terms of the Protocol will replace the terms of this paragraph. In the event of any inconsistencies between
the Agreement and the terms of the Protocol, the Bilateral Agreement or the Bilateral Terms (each, the “QFC Stay Terms”),
as applicable, the QFC Stay Terms will govern. Terms used in this paragraph without definition shall have the meanings assigned to them
under the QFC Stay Rules. For purposes of this paragraph, references to “the Agreement” include any related credit enhancements
entered into between the parties or provided by one to the other. In addition, the parties agree that the terms of this paragraph shall
be incorporated into any related covered affiliate credit enhancements, with all references to Dealer replaced by references to the covered
affiliate support provider. “QFC Stay Rules” means the regulations codified at 12 C.F.R. 252.2, 252.81–8, 12
C.F.R. 382.1-7 and 12 C.F.R. 47.1-8, which, subject to limited exceptions, require an express recognition of the stay-and-transfer powers
of the FDIC under the Federal Deposit Insurance Act and the Orderly Liquidation Authority under Title II of the Dodd Frank Wall Street
Reform and Consumer Protection Act and the override of default rights related directly or indirectly to the entry of an affiliate into
certain insolvency proceedings and any restrictions on the transfer of any covered affiliate credit enhancements.

WARRANT
AGENT AGREEMENT

 

WARRANT
AGENT AGREEMENT (this “Warrant Agreement”) dated as of February 10, 2022 (the “Issuance
Date”) between TC BioPharm (Holdings) plc, a company incorporated in Scotland, under the law of the United Kingdom (the
“Company”), and Computershare Inc., a Delaware corporation (“Computershare”), and its wholly
owned subsidiary, Computershare Trust Company, N.A., a federally chartered trust company (the “Warrant
Agent”).

 

WHEREAS,
pursuant to the terms of that certain Underwriting Agreement (“Underwriting Agreement”), dated February 10,
2022, between the Company and EF Hutton, division of Benchmark Investments, LLC, as representative of the underwriters set forth therein,
the Company is engaged in a public offering (the “Offering”) of up to 4,117,648 American Depositary Shares
(“ADSs”), each ADS representing one ordinary share of the Company, par value £0.01 per share (“Ordinary
Shares”), and up to 8,235,296 Warrants (the “Warrants”), with each Warrant representing the right
of the holder thereof to purchase two ADSs (each, a “Warrant ADS”) for $4.25 per ADS, subject to adjustment
as described herein, plus applicable fees, charges and taxes;

 

WHEREAS,
the ADSs are issuable under the Deposit Agreement dated as of February 10, 2022 (the “Deposit Agreement”) among
the Company, The Bank of New York Mellon, as depositary (the “Depositary”), and all Owners and Holders (each as defined
in the Deposit Agreement) from time to time of the ADSs issued thereunder;

 

WHEREAS,
the Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form
F-1, File No. 333-260492 (as the same may be amended from time to time, the “Registration Statement”) for the registration,
under the Securities Act of 1933, as amended (the “Securities Act”), of, among other securities, the Ordinary Shares,
the Warrants and the Ordinary Shares underlying the Warrant ADSs issuable upon exercise of the Warrants (the “Warrant Shares”),
and the Registration Statement was declared effective on February 10, 2022;

 

WHEREAS,
the Depositary has filed with the Commission a Registration Statement on Form F-6, File No. 333-262149 (the “ADS Registration
Statement”) for the registration under the Securities Act of the ADSs that may be issued in exchange for Ordinary Shares and
the Warrant Shares, and the Registration Statement was declared effective on February 10, 2022.

 

WHEREAS,
the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in accordance with
the terms set forth in this Warrant Agreement in connection with the issuance, registration, registration of transfer and exercise of
the Warrants;

 

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

 

WHEREAS,
the Company has duly authorized the execution and delivery of this Warrant Agreement and all other acts and things necessary to make
the Warrants the legal, valid and binding obligations of the Company have been done and performed.

 

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

 

1.
Appointment of Warrant Agent. The Company hereby
appoints the Warrant Agent to act as agent for the Company with respect to the Warrants, and the Warrant Agent hereby accepts such appointment
and agrees to perform the same in accordance with the express terms and conditions set forth in this Warrant Agreement (and no implied
terms or conditions).

 

    	1

     

    

 

2.
Warrants.

 

2.1
Form of Warrants. The Warrants shall be registered securities in book entry form and shall be evidenced by a global certificate
(“Global Certificate”) in the form of Annex C to this Warrant Agreement, which shall be deposited on behalf
of the Company with a custodian for The Depository Trust Company (“DTC”) and registered in the name of Cede &
Co., as nominee of DTC or as otherwise directed by DTC. If DTC subsequently ceases to make its book-entry settlement system available
for the Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event
that the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Company
may instruct the Warrant Agent to provide written instructions to DTC to deliver to the Warrant Agent for cancellation the Global Certificate,
and the Company shall instruct the Warrant Agent to deliver each holder of the Warrants separate certificates in the form of Annex
A evidencing Warrants (“Definitive Certificates” and, together with the Global Certificate, “Warrant
Certificates”) registered as requested through the DTC system. In the event Definitive Certificates are delivered to the holders,
the transfer, exchange or exercise of the Warrants shall be conducted in accordance with the customary procedures of the Warrant Agent.
The Company shall use its best efforts to enable the Warrants be “DTC eligible” so that the interests in the Warrants may
be held in book-entry through DTC for the term of the Warrants.

 

2.1.1
Exchange of Interest in Global Certificate for Definitive Certificate. Notwithstanding Section 2.1 above, a holder of a security
entitlement in Warrants evidenced by the Global Certificate has the right to elect at any time to exchange it for a Definitive Certificate
evidencing the same number of Warrants. Upon written notice by a Participant having Warrants credited to its DTC account for the exchange
of some or all that entitlement for a Definitive Certificate evidencing the same number of Warrants, which request shall be in the form
attached hereto as Annex B (a “Warrant Certificate Request Notice” and the date of delivery of such Warrant
Certificate Request Notice by the Holder, the “Warrant Certificate Request Notice Date” and the exchange made pursuant
to the Warrant Certificate Request Notice, a “Warrant Exchange”), and upon surrender by that Participant of the Warrants
to be exchanged to the Warrant Agent through DTC’s system, the Warrant Agent shall, without unreasonable delay, effect the Warrant
Exchange by issuing and delivering a Definitive Certificate for such number of Warrants in the name and mailed to the address set forth
in the Warrant Certificate Request Notice. Such Definitive Certificate shall be dated the original issue date of the Warrants, shall
be manually executed by an authorized signatory of the Company and shall be in the form attached hereto as Annex A In connection
with a Warrant Exchange, the Company agrees to deliver, or to direct the Warrant Agent to deliver, the Definitive Certificate to the
specified holder within ten (10) Business Days of the Warrant Certificate Request Notice pursuant to the delivery instructions in the
Warrant Certificate Request Notice (the “Warrant Certificate Delivery Date”). “Business Day” means
any day other than a Saturday, Sunday, or a day on which banking institutions in the State of New York are authorized or obligated by
law or executive order to close.

 

2.1.2
Opinion of Counsel. The Company shall provide to the Warrant Agent an opinion of counsel on or prior to the issuance of
Warrants to set up a reserve of Warrant Shares for the outstanding Warrants. The opinion shall state that all Warrants or Warrant Shares,
as applicable, are (i) registered under the Securities Act of 1933, as amended, and (ii) validly issued, fully paid and non-assessable.

 

2.2
Issuance and Registration of Warrants.

 

2.2.1
Warrant Register. Upon the receipt of all relevant information from the Company or its agents, the Warrant Agent shall maintain
books (“Warrant Register”) for the registration of original issuance and the registration of transfer of the Warrants.

 

2.2.2
Issuance of Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall issue the Global Certificate and deliver
the Warrants in the DTC book-entry settlement system in accordance with written instructions delivered to the Warrant Agent by the Company.
Ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records
maintained (i) by DTC and (ii) by institutions that have accounts with DTC (each, with respect to a Warrant in its account, a “Participant”).

 

    	2

     

    

 

2.2.3
Beneficial Owner; Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent
may deem and treat the person in whose name that Warrant shall be registered on the Warrant Register (the “Holder”,
which shall include, if the Warrants are held in “street name,” a Participant or a designee appointed by such Participant)
as the absolute owner of such Warrant for purposes of any exercise thereof, and for all other purposes, and neither the Company nor the
Warrant Agent shall be affected by any notice to the contrary. Notwithstanding the foregoing, nothing herein shall prevent the Company,
the Warrant Agent or any agent of the Company or the Warrant Agent from giving effect to any written certification, proxy or other authorization
furnished by DTC governing the exercise of the rights of a holder of a beneficial interest in any Warrant. The rights of beneficial owners
in a Warrant evidenced by the Global Certificate shall be exercised by the Holder through the DTC system.

 

2.2.4 Execution.
The Warrant Certificates shall be executed on behalf of the Company by any authorized officer of the Company (an “Authorized
Officer”), which need not be the same authorized signatory for all of the Warrant Certificates, either manually or by facsimile
signature. The Warrant Certificates shall be countersigned by an authorized signatory of the Warrant Agent either by manual, electronic
or facsimile signature, which need not be the same signatory for all of the Warrant Certificates, and no Warrant Certificate shall be
valid for any purpose unless so countersigned. In case any Authorized Officer of the Company that signed any of the Warrant Certificates
ceases to be an Authorized Officer of the Company before countersignature by the Warrant Agent and issuance and delivery by the Company,
such Warrant Certificates, nevertheless, may be countersigned by the Warrant Agent, issued and delivered with the same force and effect
as though the person who signed such Warrant Certificates had not ceased to be such officer of the Company; and any Warrant Certificate
may be signed on behalf of the Company by any person who, at the actual date of the execution of such Warrant Certificate, shall be an
Authorized Officer of the Company authorized to sign such Warrant Certificate, although at the date of the execution of this Warrant
Agreement any such person was not such an Authorized Officer. The rights of holders of Warrant Certificates shall be identical regardless
of the Authorized Officer signing for and on behalf of the Company and of the authorized signatory of the Warrant Agent signing such
certificates.

 

2.2.5
Registration of Transfer. At any time at or prior to the Expiration Date (as defined below), a transfer of any Warrants may be
registered and any Warrant Certificate or Warrant Certificates may be split up, combined or exchanged for another Warrant Certificate
or Warrant Certificates evidencing the same number of Warrants as the Warrant Certificate or Warrant Certificates surrendered. Any Holder
desiring to register the transfer of Warrants or to split up, combine or exchange any Warrant Certificate shall make such request in
writing delivered to the Warrant Agent, and shall surrender to the Warrant Agent the Warrant Certificate or Warrant Certificates evidencing
the Warrants the transfer of which is to be registered or that is or are to be split up, combined or exchanged and, in the case of registration
of transfer, shall provide a signature guarantee by an “eligible guarantor institution” that is a member or participant in
the Securities Transfer Agents Medallion Program or other comparable “signature guarantee program.” Thereupon, the Warrant
Agent shall countersign and deliver to the person entitled thereto a Warrant Certificate or Warrant Certificates, as the case may be,
as so requested. The Company and the Warrant Agent may require payment by the Holder requesting a registration of transfer of Warrants
or a split-up, combination or exchange of a Warrant Certificate (but, for purposes of clarity, not upon the exercise of the Warrants
and issuance of Warrant ADS to the Holder) of a sum sufficient to cover any tax or governmental charge that may be imposed in connection
with such registration of transfer, split-up, combination or exchange, together with reimbursement to the Company and the Warrant Agent
of all reasonable expenses incidental thereto. The Warrant Agent shall not have any duty or obligation to take any action under any section
of this Warrant Agreement that requires the payment of taxes and/or charges unless and until it is satisfied that all such payments have
been made.

 

2.2.6
Loss, Theft and Mutilation of Warrant Certificates. Upon receipt by the Company and the Warrant Agent of evidence reasonably satisfactory
to them of the loss, theft, destruction or mutilation of a Warrant Certificate, and, in case of loss, theft or destruction, of indemnity
or security acceptable to the Warrant Agent, and reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental
thereto, and upon surrender to the Warrant Agent and cancellation of the Warrant Certificate if mutilated, the Warrant Agent shall, on
behalf of the Company, countersign and deliver a new Warrant Certificate of like tenor to the Holder in lieu of the Warrant Certificate
so lost, stolen, destroyed or mutilated. The Warrant Agent may charge the Holder an administrative fee for processing the replacement
of lost Warrant Certificates, which shall be charged only once in instances where a single surety bond obtained covers multiple certificates.
The Warrant Agent may receive compensation from the surety companies or surety agents for administrative services provided to them. Notwithstanding
anything herein to the contrary, in connection with a Warrant in book-entry form through DTC, no posting of a bond shall be required
under this Section 2.2.6.

 

    	3

     

    

 

2.2.7
Proxies. The Holder of a Warrant may grant proxies or otherwise authorize any person, including Participants and beneficial holders
that may own interests through Participants, to take any action that a Holder is entitled to take under this Warrant Agreement or the
Warrants; provided, however, that at all times that Warrants are evidenced by a Global Certificate, exercise of those Warrants
shall be effected on their behalf by Participants through DTC in accordance with the procedures administered by DTC.

 

3.
Terms and Exercise of Warrants.

 

3.1
Exercise Price. Each Warrant shall entitle the Holder, subject to the provisions of the applicable Warrant Certificate and of
this Warrant Agreement, to purchase from the Company the number of ADSs stated therein, at the price of $4.25 per ADS, subject to the
subsequent adjustments provided in Section 4 hereof. The term “Exercise Price” as used in this Warrant Agreement refers
to the price per ADS at which ADSs may be purchased at the time a Warrant is exercised.

 

3.2
Duration of Warrants. Warrants may be exercised only during the period (“Exercise Period”) commencing on the
Issuance Date and terminating at 5:00 P.M., New York City time (the “close of business”) on February 10, 2028
(“Expiration Date”). Each Warrant not exercised on or before the Expiration Date shall become void, and all rights
thereunder and all rights in respect thereof under this Warrant Agreement shall cease at the close of business on the Expiration Date.

 

3.3
Exercise of Warrants.

 

3.3.1
Exercise and Payment. (a) Subject to the provisions of this Warrant Agreement, a Holder (or a Participant acting on behalf of
a Holder in accordance with DTC procedures) may exercise Warrants by delivering to the Warrant Agent, not later than 5:00 P.M., New York
City time, on any Business Day during the Exercise Period an election to purchase the Warrant ADSs to be exercised (A) in the form included
in Exhibit A to the Warrant or (B) via an electronic warrant exercise through the DTC system (each, an “Election to Purchase”).
Within one Trading Day following the delivery of the Election to Purchase, the Holder shall deliver (i) the Warrants to be exercised
by (A) surrender of the Warrant Certificate evidencing the Warrants to the Warrant Agent at its office designated for such purpose or
(B) delivery of the Warrants to an account of the Warrant Agent at DTC designated for such purpose in writing by the Warrant Agent to
DTC from time to time, and (ii) the Exercise Price for each Warrant to be exercised (and, if applicable, any taxes or charges due in
connection with the exercise of such Warrants), in lawful money of the United States of America by (A) certified or official bank check
or wire transfer from a United States bank payable to the Warrant Agent or (B) payment to the Warrant Agent through the DTC system.
Upon giving irrevocable instructions to its DTC participant to exercise Warrants, solely for purposes of Regulation SHO, the holder whose
interest in the Warrant is a beneficial interest shall be deemed to have exercised such Warrant, regardless of when the applicable Warrant
ADSs are delivered to such holder.

 

(b)
Upon receipt of a Notice of Exercise for a Cashless Exercise provided by a holder to the Depositary and/or the Company, as applicable
(as provided in Section 3.3.1(a) above), the Company will promptly calculate and transmit to the Warrant Agent the number of Warrant
Shares issuable in connection with such Cashless Exercise and deliver a copy of the Notice of Exercise to the Warrant Agent, which shall
cause to be delivered in accordance with the provisions of Section 7(c) such number of Warrant Shares in connection with such Cashless
Exercise.

 

(c)
Upon the exercise of the Warrant pursuant to the terms of Section 4(c) of the Warrant Certificate, the Warrant Agent shall cause the
Warrant Shares underlying such Definitive Certificate or Global Warrant to be delivered to or upon the order of the Holder of such Definitive
Certificate or Global Warrant, registered in such name or names as may be designated by such Holder, no later than the Warrant Share
Delivery Date (as such term is defined in the Warrant Certificate). If the Company is then a participant in the DWAC system of the Depositary
and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant
Shares by Holder or (B) the Warrant is being exercised via Cashless Exercise, then the certificates for Warrant Shares shall be transmitted
by the Warrant Agent to the Holder by crediting the account of the Holder’s broker with the Depositary through its DWAC system.
For the avoidance of doubt, if the Company becomes obligated to pay any amounts to any Holders pursuant to Section 4(e)(i) or 4(m) of
the Warrant Certificate, such obligation shall be solely that of the Company and not that of the Warrant Agent. Notwithstanding anything
else to the contrary in this Agreement, except in the case of a Cashless Exercise, if any Holder fails to duly deliver payment to the
Company of an amount equal to the aggregate Exercise Price of the Warrant Shares to be purchased upon exercise of such Holder’s
Warrant as set forth in this Section 3.3.1 by the Warrant Share Delivery Date, the Warrant Agent will not be obligated to deliver such
Warrant Shares (via DWAC or otherwise) until following receipt by the Company of such payment, and the applicable Warrant Share Delivery
Date shall be deemed extended by one day for each day (or part thereof) until such payment is delivered to the Company.

 

    	4

     

    

 

(d)
If any of (i) the Warrants, (ii) the Election to Purchase, or (iii)
the Exercise Price therefor (and, if applicable, any taxes or charges due in connection with the exercise of such Warrants), is received
by the Warrant Agent on any date after 5:00 P.M., New York City time, or on a date that is not a Trading Day, the Warrants with respect
thereto will be deemed to have been received and exercised on the Trading Day next succeeding such date. The “Exercise Date”
will be the date on which the Election to Purchase is delivered to the Warrant Agent; however, the Warrants shall not be deemed to be
exercised if the Warrants and the Exercise Price therefor are not received by the Warrant Agent on or prior to the Trading Day following
the delivery of the Election to Purchase. If the Warrants are received or deemed to be received after the Expiration Date, the exercise
thereof will be null and void and any funds delivered to the Warrant Agent will be returned to the Holder or Participant, as the case
may be, as soon as practicable. “Trading Day” means any day on which the ADSs are traded on the Trading Market, or,
if the Trading Market is not the principal trading market for the ADSs, then on the principal securities exchange or securities market
in the United States on which the ADSs are then traded. “Trading Market” means NYSE American, the Nasdaq Capital Market,
the Nasdaq Global Market, the Nasdaq Global Select Market or the New York Stock Exchange.

  

(e)
The Warrant Agent shall deposit all funds received
by it in payment of the Exercise Price in the account maintained by the Warrant Agent in its name as agent for the Company. The Warrant
Agent shall remit to the Company funds received for warrant exercises in a given month by the fifth Business Day of the following month
by wire transfer to an account designated by the Company, or as otherwise from time to time as reasonably requested by the Company. All
funds received by Computershare under this Agreement that are to be distributed or applied by Computershare in the performance of services
hereunder (the “Funds”) shall be held by Computershare as agent for the Company and deposited in one or more bank
accounts to be maintained by Computershare in its name as agent for the Company. Until paid pursuant to the terms of this Warrant Agreement,
Computershare will hold the Funds in deposit accounts with U.S. commercial banks with Tier 1 capital exceeding $1 billion or with ratings
above investment grade by S&P Global Ratings (LT Local Issuer Credit Rating), Moody’s Investors Service (Long Term Rating)
and Fitch Ratings, Inc. (LT Issuer Default Rating) (each as reported by Bloomberg L.P.). Computershare shall have no responsibility or
liability for any diminution of the Funds that may result from any deposit made by Computershare in accordance with this Section 3.3.1(c),
including any losses resulting from a default by any bank, financial institution or other third party. Computershare may from time to
time receive interest, dividends or other earnings in connection with such deposits. Computershare shall not be obligated to pay such
interest, dividends or earnings to the Company, any holder or any other party.

 

(f)
If less than all the Warrants evidenced by a surrendered
Warrant Certificate are exercised, the Warrant Agent shall split up the surrendered Warrant Certificate and return to the Holder a Warrant
Certificate evidencing the Warrants that were not exercised.

 

3.3.2
Issuance of Warrant Shares. (a) The Warrant Agent shall, by 11:00 a.m., New York City time, on the Trading Day following the Exercise
Date of any Warrant, advise the Company, the transfer agent and registrar for Ordinary Shares and the Depositary, in respect of (i) the
number of Warrant Shares indicated on the Election to Purchase as issuable upon such exercise with respect to such exercised Warrants,
(ii) the instructions of the Holder or Participant, as the case may be, provided to the Warrant Agent with respect to the delivery of
the Warrant ADSs and the number of Warrants that remain outstanding after such exercise and (iii) such other information as the Company
or the Depositary shall reasonably request.

 

(b)
The Company shall, by no later than 5:00 P.M., New York City time, on the Trading Day following the Exercise Date of any Warrant,
provided the funds in payment of the Exercise Price for each Warrant to be exercised have cleared on the Trading Day following the Exercise
Date, cause its registrar to deliver the Warrant Shares issuable upon that exercise to the Depositary’s custodian for deposit under
the Deposit Agreement and instruct the Depositary to deliver the Warrant ADSs issuable upon that deposit of Warrant Shares as requested
in the Election to Purchase.

 

    	5

     

    

 

(c)
The Company shall, by no later than 5:00 P.M., New York City time, on the second Trading Day following the Exercise Date of any
Warrant, provided the funds in payment of the Exercise Price for each Warrant to be exercised have cleared on the Trading Day following
the Exercise Date, cause the Depositary to deliver the Warrant ADSs to the Holder pursuant to the Election to Purchase (the “Warrant
ADS Delivery Date”).

 

3.3.3
Valid Issuance. All Warrant Shares and Warrant ADSs issuable by the Company upon the proper exercise of a Warrant in conformity
with this Warrant Agreement shall be validly issued, fully paid and non-assessable.

 

3.3.4
No Fractional Exercise. No fractional Warrant ADSs will be issued upon the exercise of the Warrant, but rather the Company shall
adjust the number of Warrant Shares issued up or down to the nearest integral multiple of the number of Ordinary Shares at the time represented
by one ADS.

 

3.3.5
No Transfer Taxes. The Company shall not be required to pay any stamp or other tax or charge required to be paid in connection
with the exercise of Warrants; and the Company shall not be required to issue or deliver any Warrant ADSs until such tax or other charge
shall have been paid or it has been established to the satisfaction of the Company and the Warrant Agent that no such tax or other charge
is due. For purposes of clarity, the Company shall pay any stamp or other tax or charge required to be paid in connection with any issuance
to the Holder of the Warrant ADSs upon the exercise of Warrants.

 

3.3.6
Date of Issuance. (a) The Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant
ADSs only on the Warrant ADS Delivery Date, except that, if the Exercise Date is a date when the stock transfer books of the Company
are closed, such person shall be deemed to have become the holder of such shares at the open of business on the next succeeding date
on which the stock transfer books are open; provided, however, Warrant ADSs will not be registered or issued until the Depositary receives
notice from its custodian that the Warrant Shares have been deposited under the Deposit Agreement; provided further, however, that the
Company shall take all reasonable steps to ensure the Warrant ADSs are delivered to the Holder on or prior to the Warrant ADS Delivery
Date in accordance with Section 3.3.2(c) hereof and, if the Warrant ADSs are not delivered to the Holder on or prior to the Warrant ADS
Delivery Date, the provisions of Section 3.3.9 shall apply.

  

(b)
No exercising Holder, which Holder effected a Warrant Exchange pursuant to Section 2.1.1 prior to the Exercise Date, shall be required
to surrender its Warrant to the Warrant Agent, unless such exercise is for the remaining numbers of ADSs issuable upon exercise of such
Warrant, in which case the Holder shall deliver the Warrant Certificate to the Warrant Agent within three (3) Business Days.

 

3.3.7
Restrictive Legend Events. (a) The Company shall use its reasonable efforts to maintain the effectiveness of the Registration
Statement and the ADS Registration Statement and the current status of the prospectuses included therein or to file and maintain the
effectiveness of another registration statement and another current prospectus covering the Warrants and the Warrant Shares at any time
that the Warrants are exercisable. The Company shall provide to the Warrant Agent and each Holder prompt written notice of any time that
the Company is unable to deliver the Warrant ADSs via DTC transfer or otherwise upon a cash exercise without restrictive legend
because (A) the Commission has issued a stop order with respect to the Registration Statement or the ADS Registration Statement, (B)
the Commission otherwise has suspended or withdrawn the effectiveness of the Registration Statement or the ADS Registration Statement,
either temporarily or permanently, (C) the Company has suspended or withdrawn the effectiveness of the Registration Statement or the
ADS Registration Statement, either temporarily or permanently, (D) the prospectuses contained in the Registration Statement and the ADS
Registration Statement are not available for the issuance of the Warrant ADSs to the Holder, (E) the Registration Statement or the ADS
Registration Statement or the prospectuses contained therein are not current and do not conform to the requirements of the applicable
rules and regulations, or the SEC has not declared effective a post-effective amendment to the Registration Statement or the ADS Registration
Statement if one is required to be filed to update the disclosures therein, or (F) otherwise (each a “Restrictive Legend Event”).
To the extent that the Warrants cannot be exercised for cash as a result of a Restrictive Legend Event, the Company shall, at
the election of the Holder, which shall be given within five (5) days of receipt of such notice of the Restrictive Legend Event, either
(A) rescind the previously submitted Election to Purchase and the Company shall return all consideration paid by registered holder
for such shares upon such rescission or (B) treat the attempted exercise as a cashless exercise as described in Section 3.3.7 (a)
below and refund the cash portion of the exercise price to the Holder.

 

    	6

     

    

 

(b)
If a Restrictive Legend Event has occurred, the Warrant may also be exercisable on a cashless basis. Notwithstanding anything herein
to the contrary, but without limiting the rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant
to this Section 3.3.7 or to receive cash payments, the Company shall not be required to make any cash payments or net cash settlement
to the Holder in lieu of delivery of the Warrant Shares. Upon a “cashless exercise”, the Holder shall be entitled to receive
the number of Warrant Shares equal to the quotient (if such quotient would be a positive number) 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 on a day
                                            that is not a Trading Day or (2) both executed and delivered on a Trading Day prior to the
                                            opening of “regular trading hours” (as defined in Rule 600(b)(77) 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 Common Stock 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 3.3.7 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 after the close of “regular trading hours” on
                                            such Trading Day;

		(B)
                                            =	the
                                            Exercise Price of the Warrant, as adjusted as set forth herein; and
	 	(X) =	the number of Warrant Shares that would be issuable
      upon exercise of the Warrant in accordance with the terms of the Warrant if such exercise were by means of a cash exercise rather
      than a cashless exercise.

 

(c)
If the Warrant Shares are issued in such a cashless exercise, the Company acknowledges and agrees that, in accordance with Section 3(a)(9)
of the Securities Act, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised and the Company
agrees not to take any position contrary thereto. Upon receipt of a Notice of Exercise for a cashless exercise, the Warrant Agent will
promptly deliver a copy of the Notice of Exercise to the Company to confirm the number of Warrant Shares issuable in connection with
the cashless exercise. The Company shall calculate and transmit to the Warrant Agent in a written notice, and the Warrant Agent shall
have no duty, responsibility or obligation under this Section 3.3.7 to calculate, the number of Warrant Shares issuable in connection
with any cashless exercise. The Warrant Agent shall be entitled to rely conclusively on any such written notice provided by the Company,
and the Warrant Agent shall not be liable for any action taken, suffered or omitted to be taken by it in accordance with such written
instructions or pursuant to this Warrant Agreement.

 

3.3.8
Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of
Warrant ADSs issuable in connection with any exercise, the Company shall promptly deliver to the Holder the number of Warrant ADSs that
are not disputed.

 

3.3.9
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 deliver the Warrant ADSs to the Holder pursuant to Section 3.3.2, and if
after such date the beneficial owner is required by its broker to purchase (in an open market transaction or otherwise) or the beneficial
owner’s brokerage firm otherwise purchases, ADSs or Ordinary Shares to deliver in satisfaction of a sale by the beneficial owner
of the Warrant ADSs, which the beneficial owner 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 beneficial owner’s total purchase price (including brokerage
commissions, if any) for the Warrant ADSs or Warrant Shares so purchased exceeds (y) the amount obtained by multiplying (i) the number
of Warrant ADSs or Warrant Shares, as applicable, that the Company was required to deliver to the Holder in connection with the exercise
at issue times (ii) 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 or Warrant Shares, as applicable, for which
such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of Warrant
ADSs or Warrant Shares, as applicable, that would have been issued had the Company timely complied with its delivery obligations. For
example, if the beneficial owner purchases ADSs or Ordinary Shares having a total purchase price (including brokerage commissions) of
$11,000 to cover a Buy-In with respect to an attempted exercise of Warrant ADSs 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
for the benefit of the beneficial owner. 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 right of a
Holder 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 Warrant ADSs upon exercise of Warrants
as required pursuant to the terms of this Warrant Agreement. The Warrant Agent shall have no liability for the Company’s failure
to deliver to the Holders the Warrant ADSs as set forth in this Section 3.3.9.

 

    	7

     

    

 

In
addition, if the Company fails for any reason to deliver to the Holder the Warrant ADSs subject to an Election to Purchase 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 ADSs on the date of the applicable Election to Purchase), $10 per Trading Day
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 transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and
exercisable. In addition, if the Company fails to cause the Depository to transmit to the Holder the Warrant ADSs by the Warrant ADS
Delivery Date, then the Holder will have the right to rescind such exercise.

 

For
purposes of this Warrant Agreement:

 

“VWAP”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the ADSs are then listed
or quoted on a Trading Market, the daily volume weighted average price of the ADSs for such date (or the nearest preceding date) on the
Trading Market on which the ADSs are 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) the volume weighted average price of the ADSs for such date (or the nearest preceding
date) on the OTC Bulletin Board, (c) if the ADSs are not then listed or quoted for trading on the OTC Bulletin Board and if prices for
the ADSs are then reported in the OTCQB maintained by OTC Markets Group, Inc. (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 Company, the fees and expenses of which shall be paid by
the Company, and

 

“Bid
Price” means, for any date, the price determined by the first of the following clauses that applies: (a) if the ADSs are then
listed or quoted on a Trading Market, the Bid Price of the ADSs for the time in question (or the nearest preceding date) on the Trading
Market on which the ADSs 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 ADSs
for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the ADSs are not then listed or quoted for trading
on OTCQB or OTCQX and if prices for the ADSs are then reported on the Pink Open Market (or a similar organization or agency succeeding
to its functions of reporting prices), the most recent Bid Price per share of the ADSs 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 Holders of a majority in interest of the
Warrants then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

 

3.3.10
The Company shall pay all Warrant Agent and Depositary fees required for timely processing of any Election to Purchase and all fees to
DTC (or another established clearing corporation performing similar functions) required for electronic issuance and delivery of the Warrant
ADSs for timely delivery of Warrant ADSs on or prior to the Warrant ADSs Delivery Date. The Company shall pay all applicable fees and
expenses of the Depositary in connection with the issuance of the Warrants ADSs hereunder.

 

    	8

     

    

 

4.
Adjustments.

 

The
Exercise Price, the number of Warrant ADSs covered by each Warrant and the number of Warrants outstanding are subject to adjustment from
time to time as provided in Section 5 of the Warrant Certificate. In the event that at any time, as a result of an adjustment made pursuant
to Section 5 of the Warrant Certificate, the Holder of any Warrant thereafter exercised shall become entitled to receive any shares of
capital stock of the Company other than Warrant ADSs, thereafter the number of such other shares so receivable upon exercise of any Warrant
shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with
respect to the shares contained in Section 5 of the Warrant Certificate with respect to the Warrant ADSs shall apply on like terms to
any such other shares. All Warrants originally issued by the Company subsequent to any adjustment made to the Exercise Price pursuant
to the Warrant Certificate shall evidence the right to purchase, at the adjusted Exercise Price, the number of Warrant ADSs purchasable
from time to time hereunder upon exercise of the Warrants, all subject to further adjustment as provided herein.

  

5.
Restrictive Legends; Fractional Warrants.

 

In
the event that a Warrant Certificate surrendered for transfer bears a restrictive legend, the Warrant Agent shall not register that transfer
until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether
the Warrants must also bear a restrictive legend upon that transfer. The Warrant Agent shall not be required to effect any registration
of transfer or exchange which will result in the transfer of or delivery of a Warrant Certificate for a fraction of a Warrant.

 

6.
Expense Reimbursement.

 

The
Company shall reimburse the Holder, upon the Holder’s request, for any reasonable fees charged to the Holder by the Depositary
in connection with the issuance or holding or sale of ADSs, Warrant ADSs and/or Ordinary Shares.

 

7.
Other Provisions Relating to Rights of Holders of
Warrants.

 

7.1
No Rights as Stockholder. Except as otherwise specifically provided herein, a Holder, solely in its capacity as a holder of Warrants,
shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall
anything contained in this Warrant Agreement be construed to confer upon a Holder, solely in its capacity as the registered holder of
Warrants, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether

officer, agent, representative or employee from acting in any other capacity for the Company or for any other person; and

 

(o)
shall not be required to take notice or be deemed to have notice of any event or condition hereunder, including any event or condition
that may require action by the Warrant Agent , unless the Warrant Agent shall be specifically notified in writing of such event or condition

under this Warrant Agreement or the rights of the Company or of any Holder, the Warrant Agent shall not be required to act and shall

be construed and enforced as if such provision had not been contained herein and shall be deemed an agreement among the parties to it
to the full extent permitted by applicable law; provided, however, that if such excluded provision shall adversely affect the rights,

a default under the articles of association, bylaws or any similar document of the Company or any indenture, agreement or instrument
to which it is a party or is bound, (c) this Warrant Agreement has been duly executed and delivered by the Company and constitutes the
legal, valid, binding and enforceable obligation of the Company, (d) the Warrants will comply in all material respects with all applicable

other party, which the other party will not unreasonably withhold, condition or delay; except that (i) consent is not required for an
assignment or delegation of duties by Warrant Agent to any affiliate of Warrant Agent and (ii) any reorganization, merger, consolidation,

of this Warrant Agreement.

 

(c)
No provision of this Warrant Agreement may be amended, modified or waived, except in a written document signed by both parties. The Company
and the Warrant Agent may amend or supplement this Warrant Agreement without the consent of any Holder for the purpose of curing any
ambiguity, or curing, correcting or supplementing any defective provision contained herein or adding or changing any other provisions
with respect to matters or questions arising under this Warrant Agreement as the parties may deem necessary or desirable and that the

Warrant Agent, after giving thirty (30) days’ notice in writing to the Warrant Agent or successor Warrant Agent. In the event any

resigned automatically and be discharged from its duties under this Warrant Agreement as of the effective date of such termination, If
the office of the Warrant Agent becomes vacant by resignation, termination or incapacity to act or otherwise, the Company shall appoint
in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period
of 30 days after it has been notified in writing of such resignation or incapacity by the Warrant Agent, then the Warrant Agent or any
Holder may apply to any court of competent jurisdiction for the appointment of a successor Warrant Agent at the Company’s cost.
Pending appointment of a successor to such Warrant Agent, either by the Company or by such a court, the duties of the Warrant Agent shall
be carried out by the Company. Any successor Warrant Agent (but not including the initial Warrant Agent), whether appointed by the Company
or by such court, shall be a person organized and existing under the laws of any state of the United States of America, in good standing,
and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority.
After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations
of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed,
and except for executing and delivering documents as provided in the sentence that follows, the predecessor Warrant Agent shall have
no further duties, obligations, responsibilities or liabilities hereunder, but shall be entitled to all rights that survive the termination
of this Warrant Agreement and the resignation or removal of the Warrant Agent , including but not limited to its right to indemnity hereunder.
If for any reason it becomes necessary or appropriate or at the request of the Company, the predecessor Warrant Agent shall execute and
deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights
of such predecessor Warrant Agent hereunder, except the rights and immunities retained by the predecessor Warrant Agent under the terms
hereof; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver at the expense of the
Company any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all
such authority, powers, rights, immunities, duties, and obligations.

 

8.13.2
Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof
to the predecessor Warrant Agent and the transfer agent for the ADSs not later than the effective date of any such appointment.

 

    	14

     

    

 

8.13.3

may be consolidated or any person resulting from any merger, conversion or consolidation to which the Warrant Agent shall be a party
or any person succeeding to the shareowner services business of the Warrant Agent or any successor Warrant Agent shall be the successor
Warrant Agent under this Warrant Agreement, without any further act or deed. For purposes of this Warrant Agreement, “person”

stipulation, promise, or agreement hereof.

Section
2. Warrants.

 

a)
Form of Warrants. The Warrants shall be registered securities in book entry form and shall be evidenced by a global certificate
(“Global Certificate”) in the form of this Annex A to the Warrant Agreement, which shall be deposited on behalf
of the Company with a custodian for The Depository Trust Company (“DTC”) and registered in the name of Cede &
Co., as nominee of DTC. If DTC subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may
instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Warrants are not eligible
for, or it is no longer necessary to have the Warrants available in, book-entry form, the Company may instruct the Warrant Agent to provide
written instructions to DTC to deliver to the Warrant Agent for cancellation the Global Certificate, and the Company shall instruct the
Warrant Agent to deliver each holder of the Warrants separate certificates in the form of Annex A evidencing Warrants (“Definitive
Certificates” and, together with the Global Certificate, “Warrant Certificates”) registered as requested
through the DTC system. In the event Definitive Certificates are delivered to the holders, the transfer, exchange or exercise of the
Warrants shall be conducted in accordance with the customary procedures of the Warrant Agent. The Company shall use its best efforts
to enable the Warrants be “DTC eligible” so that the interests in the Warrants may be held in book-entry through DTC for
the term of the Warrants.

 

b)
Exchange of Interest in Global Certificate for Definitive Certificate. Notwithstanding Section 2(a) above, a holder of a security
entitlement in Warrants evidenced by the Global Certificate has the right to elect at any time to exchange it for a Definitive Certificate
evidencing the same number of Warrants. Upon written notice by a participant having Warrants credited to its DTC account for the exchange
of some or all that entitlement for a Definitive Certificate evidencing the same number of Warrants, which request shall be in the form
attached to the Warrant Agreement in the form of Annex B (a “Warrant Certificate Request Notice” and the date
of delivery of such Warrant Certificate Request Notice by the Holder, the “Warrant Certificate Request Notice Date”
and the exchange made pursuant to the Warrant Certificate Request Notice, a “Warrant Exchange”), and upon surrender
by that Participant of the Warrants to be exchanged to the Warrant Agent through DTC’s system, the Warrant Agent shall, without
unreasonable delay, effect the Warrant Exchange by issuing and delivering a Definitive Certificate for such number of Warrants in the
name and mailed to the address set forth in the Warrant Certificate Request Notice. Such Definitive Certificate shall be dated the original
issue date of the Warrants, shall be manually executed by an authorized signatory of the Company and shall be in the form attached to
the Warrant Agreement as Annex A In connection with a Warrant Exchange, the Company agrees to deliver, or to direct the Warrant
Agent to deliver, the Definitive Certificate to the specified holder within ten (10) Business Days of the Warrant Certificate Request
Notice pursuant to the delivery instructions in the Warrant Certificate Request Notice (the “Warrant Certificate Delivery Date”).

 

    	20

     

    

 

Section
3. Issuance and Registration of Warrants.

 

a)
Warrant Register. Upon the receipt of all relevant information from the Company or its agents, the Warrant Agent shall maintain
books (“Warrant Register”) for the registration of original issuance and the registration of transfer of the Warrants.

 

b)
Issuance of Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall issue the Global Certificate and deliver
the Warrants in the DTC book-entry settlement system in accordance with written instructions delivered to the Warrant Agent by the Company.
Ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records
maintained (i) by DTC and (ii) by institutions that have accounts with DTC (each, with respect to a Warrant in its account, a “Participant”).

 

c)
Beneficial Owner; Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent
may deem and treat the person in whose name that Warrant shall be registered on the Warrant Register (the “Holder”,
which shall include, if the Warrants are held in “street name,” a participant or a designee appointed by such participant)
as the absolute owner of such Warrant for purposes of any exercise thereof, and for all other purposes, and neither the Company nor the
Warrant Agent shall be affected by any notice to the contrary. Notwithstanding the foregoing, nothing herein shall prevent the Company,
the Warrant Agent or any agent of the Company or the Warrant Agent from giving effect to any written certification, proxy or other authorization
furnished by DTC governing the exercise of the rights of a holder of a beneficial interest in any Warrant. The rights of beneficial owners
in a Warrant evidenced by the Global Certificate shall be exercised by the Holder through the DTC system.

 

d)
Execution. The Warrant Certificates shall be executed on behalf of the Company by any authorized officer of the Company (an “Authorized
Officer”), which need not be the same authorized signatory for all of the Warrant Certificates, either manually or by facsimile
signature. The Warrant Certificates shall be countersigned by an authorized signatory of the Warrant Agent either by manual, electronic
or facsimile signature, which need not be the same signatory for all of the Warrant Certificates, and no Warrant Certificate shall be
valid for any purpose unless so countersigned. In case any Authorized Officer of the Company that signed any of the Warrant Certificates
ceases to be an Authorized Officer of the Company before countersignature by the Warrant Agent and issuance and delivery by the Company,
such Warrant Certificates, nevertheless, may be countersigned by the Warrant Agent, issued and delivered with the same force and effect
as though the person who signed such Warrant Certificates had not ceased to be such officer of the Company; and any Warrant Certificate
may be signed on behalf of the Company by any person who, at the actual date of the execution of such Warrant Certificate, shall be an
Authorized Officer of the Company authorized to sign such Warrant Certificate, although at the date of the execution of this Warrant
Agreement any such person was not such an Authorized Officer. The rights of holders of Warrant Certificates shall be identical regardless
of the Authorized Officer signing for and on behalf of the Company and of the authorized signatory of the Warrant Agent signing such
certificates.

 

e)
Registration of Transfer. At any time at or prior to the Expiration Date (as defined below), a transfer of any Warrants may be
registered and any Warrant Certificate or Warrant Certificates may be split up, combined or exchanged for another Warrant Certificate
or Warrant Certificates evidencing the same number of Warrants as the Warrant Certificate or Warrant Certificates surrendered. Any Holder
desiring to register the transfer of Warrants or to split up, combine or exchange any Warrant Certificate shall make such request in
writing delivered to the Warrant Agent, and shall surrender to the Warrant Agent the Warrant Certificate or Warrant Certificates evidencing
the Warrants the transfer of which is to be registered or that is or are to be split up, combined or exchanged and, in the case of registration
of transfer, shall provide a signature guarantee by an “eligible guarantor institution” that is a member or participant in
the Securities Transfer Agents Medallion Program or other comparable “signature guarantee program.” Thereupon, the Warrant
Agent shall countersign and deliver to the person entitled thereto a Warrant Certificate or Warrant Certificates, as the case may be,
as so requested. The Company and the Warrant Agent may require payment by the Holder requesting a registration of transfer of Warrants
or a split-up, combination or exchange of a Warrant Certificate (but, for purposes of clarity, not upon the exercise of the Warrants
and issuance of Warrant ADS to the Holder) of a sum sufficient to cover any tax or governmental charge that may be imposed in connection
with such registration of transfer, split-up, combination or exchange, together with reimbursement to the Company and the Warrant Agent
of all reasonable expenses incidental thereto. The Warrant Agent shall not have any duty or obligation to take any action under any section
of this Warrant that requires the payment of taxes and/or charges unless and until it is satisfied that all such payments have been made.

 

    	21

     

    

 

f)
Loss, Theft and Mutilation of Warrant Certificates. Upon receipt by the Company and the Warrant Agent of evidence reasonably satisfactory
to them of the loss, theft, destruction or mutilation of a Warrant Certificate, and, in case of loss, theft or destruction, of indemnity
or security acceptable to the Warrant Agent, and reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental
thereto, and upon surrender to the Warrant Agent and cancellation of the Warrant Certificate if mutilated, the Warrant Agent shall, on
behalf of the Company, countersign and deliver a new Warrant Certificate of like tenor to the Holder in lieu of the Warrant Certificate
so lost, stolen, destroyed or mutilated. The Warrant Agent may charge the Holder an administrative fee for processing the replacement
of lost Warrant Certificates, which shall be charged only once in instances where a single surety bond obtained covers multiple certificates.
The Warrant Agent may receive compensation from the surety companies or surety agents for administrative services provided to them. Notwithstanding
anything herein to the contrary, in connection with a Warrant in book-entry form through DTC, no posting of a bond shall be required
under this Section 3(f).

 

g)
Proxies. The Holder of a Warrant may grant proxies or otherwise authorize any person, including participants and beneficial holders
that may own interests through participants, to take any action that a Holder is entitled to take under this Warrant; provided,
however, that at all times that Warrants are evidenced by a Global Certificate, exercise of those Warrants shall be effected on
their behalf by participants through DTC in accordance with the procedures administered by DTC.

 

Section
4. Exercise.

 

a)
Exercise Price. Each Warrant shall entitle the Holder, subject to the provisions of the of this Warrant, to purchase from the
Company the number of ADSs stated therein, at the price of $4.25 per ADS, subject to the subsequent adjustments provided in Section 5
hereof.

 

b)
Duration of Warrants. Warrants may be exercised only during the period (“Exercise Period”) commencing on the
Issuance Date and terminating at 5:00 P.M., New York City time (the “close of business”) on February 10, 2028
(“Expiration Date”). Each Warrant not exercised on or before the Expiration Date shall become void, and all rights
thereunder and all rights in respect thereof under this Warrant Agreement shall cease at the close of business on the Expiration Date.

 

c)
Exercise. Subject to the provisions of this Warrant, a Holder (or a participant acting on behalf of a Holder in accordance with
DTC procedures) may exercise Warrants by delivering to the Warrant Agent, not later than 5:00 P.M., New York City time, on any Business
Day during the Exercise Period an election to purchase the Warrant ADSs to be exercised (A) in the form included in Exhibit A
to this Warrant or (B) via an electronic warrant exercise through the DTC system (each, an “Election to Purchase”).
Within one Trading Day following the delivery of the Election to Purchase, the Holder shall deliver (i) the Warrants to be exercised
by (A) surrender of the Warrant Certificate evidencing the Warrants to the Warrant Agent at its office designated for such purpose or
(B) delivery of the Warrants to an account of the Warrant Agent at DTC designated for such purpose in writing by the Warrant Agent to
DTC from time to time, and (ii) unless the cashless exercise procedure specified in Section 4(d) below is specified in the applicable
Notice of Exercise, the Exercise Price for each Warrant to be exercised (and, if applicable, any taxes or charges due in connection
with the exercise of such Warrants), in lawful money of the United States of America by (A) certified or official bank check or wire
transfer from a United States bank payable to the Warrant Agent or (B) payment to the Warrant Agent through the DTC system.

 

    	22

     

    

 

If
any of (i) the Warrants, (ii) the Election to Purchase, or (iii) the Exercise Price therefor (and, if applicable, any taxes or charges
due in connection with the exercise of such Warrants), is received by the Warrant Agent on any date after 5:00 P.M., New York City time,
or on a date that is not a Trading Day, the Warrants with respect thereto will be deemed to have been received and exercised on the Trading
Day next succeeding such date. The “Exercise Date” will be the date on which the Election to Purchase is delivered
to the Warrant Agent; however, the Warrants shall not be deemed to be exercised if the Warrants and the Exercise Price therefor are not
received by the Warrant Agent on or prior to the Trading Day following the delivery of the Election to Purchase. If the Warrants are
received or deemed to be received after the Expiration Date, the exercise thereof will be null and void and any funds delivered to the
Warrant Agent will be returned to the Holder or participant, as the case may be, as soon as practicable.

 

The
Warrant Agent shall deposit all funds received by it in payment of the Exercise Price in the account maintained by the Warrant Agent
in its name as agent for the Company. The Warrant Agent shall remit to the Company funds received for warrant exercises in a given month
by the fifth Business Day of the following month by wire transfer to an account designated by the Company, or as otherwise from time
to time as reasonably requested by the Company. All funds received by Computershare under this Agreement that are to be distributed or
applied by Computershare in the performance of services hereunder (the “Funds”) shall be held by Computershare as agent for
the Company and deposited in one or more bank accounts to be maintained by Computershare in its name as agent for the Company. Until
paid pursuant to the terms of this Warrant Agreement, Computershare will hold the Funds in deposit accounts with U.S. commercial banks
with Tier 1 capital exceeding $1 billion or with ratings above investment grade by S&P Global Ratings (LT Local Issuer Credit Rating),
Moody’s Investors Service (Long Term Rating) and Fitch Ratings, Inc. (LT Issuer Default Rating) (each as reported by Bloomberg
L.P.). Computershare shall have no responsibility or liability for any diminution of the Funds that may result from any deposit made
by Computershare in accordance with this Section 4(c), including any losses resulting from a default by any bank, financial institution
or other third party. Computershare may from time to time receive interest, dividends or other earnings in connection with such deposits.
Computershare shall not be obligated to pay such interest, dividends or earnings to the Company, any holder or any other party.

 

If
less than all the Warrants evidenced by a surrendered Warrant Certificate are exercised, the Warrant Agent shall split up the surrendered
Warrant Certificate and return to the Holder a Warrant Certificate evidencing the Warrants that were not exercised.

 

(d)
Cashless Exercise. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus
contained therein is not available for the issuance of the Warrant Shares to the Holder, then 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 Shares 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)(77) 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 Common Stock on the principal Trading Market as reported by Bloomberg L.P. (“Bloomberg”) 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

 

    	23

     

    

 

	 	(X)
    =	the
    number of Warrant Shares 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.

 

Notwithstanding
anything herein to the contrary, but without limiting the rights of a Holder to receive Warrant Shares on a “cashless exercise”
pursuant to this Section 2(d) or to receive cash payments pursuant to Section 4(e)(i) and Section 4(m) herein, the Company shall not
be required to make any cash payments or net cash settlement to the Holder in lieu of delivery of the Warrant Shares. The original Holder
has paid $0.005 towards the nominal value of the Warrant Shares to be used in the event of a cashless exercise and, no additional consideration
for the nominal value shall be required to be paid by the Holder to effect an exercise of this Warrant. The Holder shall not be entitled
to the return or refund of all, or any portion, of such pre-funded nominal value under any circumstance or for any reason whatsoever,
including in the event this Warrant shall not have been exercised prior to the Termination Date. If Warrant 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 Warrant Shares
shall take on the registered characteristics of the Warrants being exercised. The Company agrees not to take any position contrary to
this Section 2(d).

 

(e)
Mechanics of Exercise.

 

i.
Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by
the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository
Trust Company through its Deposit and Withdrawal at Custodian system (“DWAC”) if the Company is then a participant
in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale
of the Warrant Shares by Holder or (B) this Warrant is being exercised via cashless exercise, and otherwise by physical delivery of a
certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant Shares
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 earliest of (i) two (2) Trading Days after the delivery to the Company of the Notice of Exercise, (ii) one (1) Trading Day
after delivery of the aggregate Exercise Price to the Company and (iii) 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 Share Delivery Date”).
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 Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares,
provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within the earlier
of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period following delivery of the Notice
of Exercise. If the Company fails for any reason to deliver to the Holder the Warrant Shares subject to a Notice of Exercise by the Warrant
Share 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
Shares subject to such exercise (based on the VWAP of the Common Stock 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 Share Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise. The Company agrees to maintain
a transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. As used herein,
“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 Common Stock 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 Underwriting Agreement, the Company agrees to deliver the
Warrant Shares 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 Share Delivery Date for purposes hereunder, provided that payment of the aggregate Exercise Price (other than in
the case of a cashless exercise) is received by such Warrant Share Delivery Date

 

    	24

     

    

 

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 certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant
evidencing the rights of the Holder to purchase the unpurchased Warrant Shares 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 Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section
4(e)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

 

f)
Issuance of Warrant Securities. The Warrant
Agent shall, by 11:00 a.m., New York City time, on the Trading Day following the Exercise Date of any Warrant, advise the Company, the
transfer agent and registrar for ordinary shares and the Depositary, in respect of (i) the number of Warrant ADSs indicated on the Election
to Purchase as issuable upon such exercise with respect to such exercised Warrants, (ii) the instructions of the Holder or Participant,
as the case may be, provided to the Warrant Agent with respect to the delivery of the Warrant ADSs and the number of Warrants that remain
outstanding after such exercise and (iii) such other information as the Company or the Depositary shall reasonably request.

 

The
Company shall, by no later than 5:00 P.M., New York City time, on the Trading Day following the Exercise Date of any Warrant,
provided the funds in payment of the Exercise Price for each Warrant to be exercised have cleared on the Trading Day following the Exercise
Date, cause its registrar to deliver the Warrant ADSs issuable upon that exercise to the Depositary’s custodian for deposit under
the Deposit Agreement and instruct the Depositary to deliver the Warrant ADSs issuable upon that deposit of ordinary shares as requested
in the Election to Purchase Warrant ADSs.

 

The
Company shall, by no later than 5:00 P.M., New York City time, on the second Trading Day following the Exercise Date of any Warrant,
provided the funds in payment of the Exercise Price for each Warrant to be exercised have cleared on the Trading Day following the Exercise
Date, cause the Depositary to deliver the Warrant ADSs to the Holder pursuant to the Election to Purchase (the “Warrant ADS Delivery
Date”).

 

g)
Valid Issuance. All Warrant ADSs issuable
by the Company upon the proper exercise of a Warrant in conformity with this Warrant Agreement shall be validly issued and fully paid.

 

h)
No Fractional Exercise. No fractional Warrant
ADSs will be issued upon the exercise of the Warrant, but rather the Company shall adjust the number of Warrant ADSs issued up or down
to the nearest integral multiple of the number of ADSs representing the ordinary shares.

 

i)
No Transfer Taxes. The Company shall not
be required to pay any stamp or other tax or charge required to be paid in connection with the exercise of Warrants; and the Company
shall not be required to issue or deliver any ADSs until such tax or other charge shall have been paid or it has been established to
the satisfaction of the Company and the Warrant Agent that no such tax or other charge is due. For purposes of clarity, the Company shall
pay any stamp or other tax or charge required to be paid in connection with any issuance to the Holder of the Warrant ADSs upon the exercise
of Warrants.

 

j)
Date of Issuance. (a) The Holder shall be
deemed for all corporate purposes to have become the holder of record of the Warrant ADSs only on the Warrant ADS Delivery Date, except
that, if the Exercise Date is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become
the holder of such shares at the open of business on the next succeeding date on which the stock transfer books are open; provided, however,
Warrant ADSs will not be registered or issued until the Depositary receives notice from its custodian that the ordinary shares relating
to the ADSs have been deposited under the Deposit Agreement; provided further, however, that the Company shall take all reasonable steps
to ensure the Warrant ADSs are delivered to the Holder on or prior to the Warrant ADS Delivery Date in accordance with Section 4(d) hereof
and, if the Warrant ADSs are not delivered to the Holder on or prior to the Warrant ADS Delivery Date, the provisions of Section 4(m)
shall apply.

exercising Holder, which Holder effected a Warrant Exchange pursuant to Section 2(b) prior to the Exercise Date, shall be required to
surrender its Warrant to the Warrant Agent, unless such exercise is for the remaining numbers of ADSs issuable upon exercise of such
Warrant, in which case the Holder shall deliver the Warrant Certificate to the Warrant Agent within three (3) Business Days.

 

k)
Restrictive Legend Events. The Company shall
use its commercially reasonable efforts to maintain the effectiveness of the Registration Statement and the ADS Registration Statement
and the current status of the prospectuses included therein or to file and maintain the effectiveness of another registration statement
and another current prospectus covering the Warrants and the Warrant ADSs (and related ordinary shares) at any time that the Warrants
are exercisable. The Company shall provide to the Warrant Agent and each Holder prompt written notice of any time that the Company is
unable to deliver the Warrant ADSs via DTC transfer or otherwise upon a cash exercise without restrictive legend because (A) the
Commission has issued a stop order with respect to the Registration Statement or the ADS Registration Statement, (B) the Commission otherwise
has suspended or withdrawn the effectiveness of the Registration Statement or the ADS Registration Statement, either temporarily or permanently,
(C) the Company has suspended or withdrawn the effectiveness of the Registration Statement or the ADS Registration Statement, either
temporarily or permanently, (D) the prospectuses contained in the Registration Statement and the ADS Registration Statement are not available
for the issuance of the Warrant ADSs to the Holder, (E) the Registration Statement or the ADS Registration Statement or the prospectuses
contained therein are not current and do not conform to the requirements of the applicable rules and regulations, or the SEC has not
declared effective a post-effective amendment to the Registration Statement or the ADS Registration Statement are if one is required
to be filed to update the disclosures therein, or (F) otherwise (each a “Restrictive Legend Event”). To the extent
that the Warrants cannot be exercised for cash as a result of a Restrictive Legend Event, the Company shall, at the election of
the Holder, which shall be given within five (5) days of receipt of such notice of the Restrictive Legend Event, either (A) rescind
the previously submitted Election to Purchase and the Company shall return all consideration paid by registered holder for such shares
upon such rescission or (B) treat the attempted exercise as a cashless exercise as described in Section 4(d) above.

 

l)
Disputes. In the case of a dispute as to
the determination of the Exercise Price or the arithmetic calculation of the number of Warrant ADSs issuable in connection with any exercise,
the Company shall promptly deliver to the Holder the number of Warrant ADSs that are not disputed.

 

m)
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 deliver the Warrant ADSs to the Holder pursuant to Section 4(e), and if after such date the beneficial owner is required by
its broker to purchase (in an open market transaction or otherwise) or the beneficial owner’s brokerage firm otherwise purchases,
ADSs or ordinary shares to deliver in satisfaction of a sale by the beneficial owner of the Warrant ADSs, which the beneficial owner
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 beneficial owner’s total purchase price (including brokerage commissions, if any) for the Warrant ADSs
so purchased exceeds (y) the amount obtained by multiplying (i) the number of Warrant ADSs, as applicable, that the Company was required
to deliver to the Holder in connection with the exercise at issue times (ii) 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, as applicable, for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the
Holder the number of Warrant ADSs, as applicable, that would have been issued had the Company timely complied with its delivery obligations.
For example, if the beneficial owner purchases ADSs having a total purchase price (including brokerage commissions) of $11,000 to cover
a Buy-In with respect to an attempted exercise of Warrant ADSs 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 for the benefit
of the beneficial owner. 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 right of a Holder 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 Warrant ADSs upon exercise of Warrants as required
pursuant to the terms of this Warrant Agreement. The Warrant Agent shall have no liability for the Company’s failure to deliver
to the Holders the Warrant ADSs as set forth in this Section 4(m).

 

    	26

     

    

 

In
addition, if the Company fails for any reason to deliver to the Holder the Warrant ADSs subject to an Election to Purchase 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 ADSs on the date of the applicable Election to Purchase), $10 per Trading Day
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 transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and
exercisable. In addition, if the Company fails to cause the Depository to transmit to the Holder the Warrant ADSs by the Warrant ADS
Delivery Date, then the Holder will have the right to rescind such exercise.

 

n)
Expenses. The Company shall pay all Warrant
Agent and Depositary fees required for timely processing of any Election to Purchase and all fees to DTC (or another established clearing
corporation performing similar functions) required for electronic issuance and delivery of the Warrant ADSs for timely delivery of Warrant
ADSs on or prior to the Warrant ADSs Delivery Date. The Company shall pay all applicable fees and expenses of the Depositary in connection
with the issuance of the Warrants ADSs hereunder.

 

Section
5. Certain Adjustments.

 

	 	a)	Stock
                                            Dividends and Splits. If the Company, at any time while this Warrant is outstanding:
		i)	pays
                                            a stock dividend or otherwise makes a distribution or distributions on Ordinary Shares or
                                            any other equity or Equivalent Securities payable in Ordinary Shares (which, for avoidance
                                            of doubt, shall not include any Warrant ADSs issued by the Company upon exercise of this
                                            Warrant), 

		ii)	subdivides
                                            outstanding Ordinary Shares into a larger number of shares, 

		iii)	combines
                                            (including by way of reverse stock split) outstanding Ordinary Shares into a smaller number
                                            of shares, or 

		iv)	issues
                                            by reclassification of Ordinary Shares any shares of capital stock of the Company, 

 

then
in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of Ordinary Shares and such
other capital stock of the Company (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator
shall be the number of Ordinary Shares and such other capital stock of the Company (excluding treasury shares, if any) outstanding immediately
after such event, and the number of ADSs 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 5(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.

 

b)
Subsequent Equity Sales. If the Company or any Subsidiary thereof, as applicable, at any time while this Warrant is outstanding,
shall sell, enter into an agreement to sell, or grant any option to purchase, or sell, enter into an agreement to 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 Equivalent Securities, at an effective price per share less than the Exercise Price then in effect (such lower
price, the “Base Share Price” and such issuances collectively, a “Dilutive Issuance”) (it being
understood and agreed that if the holder of the Ordinary Shares or such other securities so issued shall at any time, whether by operation
of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options
or rights per share which are issued in connection with such issuance, be entitled to receive Ordinary Shares at an effective price per
share that is less than the Exercise Price, such issuance shall be deemed to have occurred for less than the Exercise Price on such date
of the Dilutive Issuance at such effective price), then simultaneously with the consummation (or, if earlier, the announcement) of each
Dilutive Issuance the Exercise Price shall be reduced and only reduced to equal the Base Share Price provided that the Base Share Price
shall not be less than $0.50 (subject to adjustment for reverse and forward stock splits, recapitalizations and similar transactions
following the Initial Issuance Date). Notwithstanding the foregoing, no adjustments shall be made, paid or issued under this Section
5(b) in respect of an Exempt Issuance. The Company shall notify the Holder, in writing, no later than the Trading Day following the issuance
or deemed issuance of any Ordinary Shares Stock or Equivalent Securities subject to this Section 5(b), indicating therein the applicable
issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such notice, the “Dilutive
Issuance Notice”). For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to
this Section 5(b), upon the occurrence of any Dilutive Issuance, the Holder is entitled to receive a number of Warrant Shares based upon
the Base Share Price regardless of whether the Holder accurately refers to the Base Share Price in the Notice of Exercise. If the Company
enters into a Variable Rate Transaction, the Company shall be deemed to have issued Ordinary Shares or Equivalent Securities at the lowest
possible price, conversion price or exercise price at which such securities may be issued, converted or exercised.

 

    	27

     

    

 

c)
Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 5(a) above, if at any time the Company grants,
issues or sells any Equivalent Securities or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of Common Stock (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 ADSs acquirable upon complete exercise of this Warrant 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 are to be
determined for the grant, issue or sale of such Purchase Rights.

 

d)
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, by way of return of capital or otherwise
(including, without limitation, any distribution of cash, stock 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 ADSs acquirable upon complete exercise
of this Warrant 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 are to be determined for the participation in such Distribution. To the extent that
this Warrant has not been partially or completely exercised at the time of such Distribution, such portion of the Distribution shall
be held in abeyance for the benefit of the Holder until the Holder has exercised this Warrant.

  

e)
Fundamental Transaction. If, at any time while the Warrants are 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, 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 ordinary shares (including those
                                            represented by 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 total voting
                                            power of the Company’s ordinary shares (including those represented by ADSs) (not including
                                            any ordinary shares (including those represented by ADSs) held by the other person or other
                                            persons making or party to, or associated or affiliated with the other persons making, such
                                            purchase offer, tender offer or exchange offer); 

 

    	28

     

    

 

		(iv)	the
                                            Company, directly or indirectly, in one or more related transactions effects any reclassification,
                                            reorganization or recapitalization of ADSs or ordinary shares or any compulsory share exchange
                                            pursuant to which the ADSs or ordinary shares are 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 or scheme of arrangement) with another person
                                            or group of persons whereby such other person or group acquires more than 50% of the total
                                            voting power of the Company’s ordinary shares (including those represented by ADSs)
                                            (not including any ordinary shares (including those represented by ADSs) held by the other
                                            person or group or other persons or group making or party to, or associated or affiliated
                                            with the other persons or group making or party to, such stock or share purchase agreement
                                            or other business combination) (each a “Fundamental Transaction”), 

 

then,
upon any subsequent exercise of a Warrant, the Holder shall have the right to receive, for each Warrant ADS that would have been issuable
upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder, the number of shares
of capital stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, or depositary shares
representing those shares, 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. For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such
Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one ADS in such Fundamental Transaction
and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value
of any different components of the Alternate Consideration. 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.

 

Notwithstanding
anything to the contrary, in the event of a Fundamental Transaction, the Company or any Successor Entity (as defined below) shall, at
the Holder’s option, exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction
(or, if later, the date of the public announcement of the applicable Fundamental Transaction), purchase this Warrant from the Holder
by paying to the Holder an amount of cash equal to the Black Scholes Value (as defined below) of the remaining unexercised portion of
this Warrant on the date of the consummation of such Fundamental Transaction; provided, however, that, if the Fundamental Transaction
is not within the Company’s control, including not approved by the Company’s Board of Directors, Holder shall only be entitled
to receive from the Company or any Successor Entity the same type or form of consideration (and in the same proportion), at the Black
Scholes Value of the unexercised portion of this Warrant, that is being offered and paid to the holders of ordinary shares (including
those represented by ADSs) of the Company in connection with the Fundamental Transaction, whether that consideration be in the form of
cash, stock or any combination thereof, or whether the holders of ordinary shares (including those represented by ADSs) are given the
choice to receive from among alternative forms of consideration in connection with the Fundamental Transaction; provided, further, that
if holders of ordinary shares (including those represented by ADSs) of the Company are not offered or paid any consideration in such
Fundamental Transaction, such holders will be deemed to have received common stock of the Successor Entity (which Entity may be the Company
following such Fundamental Transaction) in such Fundamental Transaction.

 

    	29

     

    

 

“Black
Scholes Value” means the value of this Warrant based on the Black-Scholes Option Pricing Model obtained from the “OV”
function on Bloomberg determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting
(A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement
of the applicable Fundamental Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and the 100
day volatility obtained from the HVT function on Bloomberg (determined utilizing a 365 day annualization factor) as of the Trading Day
immediately following the public announcement of the applicable Fundamental Transaction, (C) the underlying price per share used in such
calculation shall be the greater of (i) the sum of the price per share being offered in cash, if any, plus the value of any non-cash
consideration, if any, being offered in such Fundamental Transaction and (ii) the highest VWAP during the period beginning on the Trading
Day immediately preceding the announcement of the applicable Fundamental Transaction (or the consummation of the applicable Fundamental
Transaction, if earlier) and ending on the Trading Day of the Holder’s request pursuant to this Section 3(e) and (D) a remaining
option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination
Date and (E) a zero cost of borrow. The payment of the Black Scholes Value will be made by wire transfer of immediately available funds
(or such other consideration) within the later of (i) five (5) Business Days of the Holder’s election and (ii) the date of consummation
of the 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 in accordance with the provisions of
this Section 5(e) pursuant to written agreements in form 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 such 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 that
is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the
Warrant ADSs acquirable and receivable upon exercise of this Warrant prior to such Fundamental Transaction and with an exercise price
which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the ADSs or
ordinary shares prior to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital
stock and such exercise price being for the purpose of protecting the economic value this Warrant had immediately prior to the consummation
of such Fundamental Transaction). 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 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 Agreement and the Warrant with the same effect as if such Successor Entity had
been named as the Company herein.

 

The
Company shall instruct the Warrant Agent in writing to mail, by first class mail, postage prepaid, to each Holder, written notice of
the execution of any such amendment, supplement or agreement with the Successor Entity. Any supplemented or amended agreement entered
into by the successor corporation or transferee shall provide for adjustments, which shall be as nearly equivalent as may be practicable
to the adjustments provided for in this Section 5(e). The Warrant Agent shall have no duty, responsibility or obligation to determine
the correctness of any provisions contained in such agreement or such notice, including but not limited to any provisions relating either
to the kind or amount of securities or other property receivable upon exercise of warrants or with respect to the method employed and
provided therein for any adjustments, and shall be entitled to rely conclusively for all purposes upon the provisions contained in any
such agreement. The provisions of this Section 5(e) shall similarly apply to successive reclassifications, changes, consolidations, mergers,
sales and conveyances of the kind described above.

  

f)
Calculations. All calculations under this Section 5 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 5, the number of shares deemed to be issued and outstanding as of a given date shall be the sum
of the number shares (excluding treasury shares, if any) issued and outstanding.

 

g)
Notice to Holder.

 

i.
Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 5, the
Company shall promptly deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment
and any resulting adjustment to the number of Warrant ADSs and setting forth a brief statement of the facts requiring such
adjustment.

 

    	30

     

    

 

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 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 shareholders of the Company shall be required in connection with any reclassification
of Ordinary Shares, any consolidation or merger to which the Company (or any of its Subsidiaries) is a party, any sale or transfer of
all or substantially all of the assets of the Company, or any compulsory share exchange whereby 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 record of Ordinary Shares 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 record of the Ordinary Shares 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 8-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.

 

h)
Voluntary Adjustment by Company. Subject to the rules and regulations of the Trading Market, the Company may at any time during the term
of this Warrant, subject to the prior written consent of the Holder, reduce the then current Exercise Price to any amount and for any
period of time deemed appropriate by the board of directors of the Company.

 

Section
6.  Miscellaneous.

 

a)
No Rights as Stockholder. Except as otherwise specifically provided herein, a Holder, solely in its capacity as a holder of Warrants,
shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall
anything contained in this Warrant be construed to confer upon a Holder, solely in its capacity as the registered holder of Warrants,
any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any
reorganization, issue of stock, reclassification of share capital, consolidation, merger, conveyance or otherwise), receive notice of
meetings, receive dividends or subscription rights or rights to participate in new issues of shares, or otherwise, prior to the issuance
to the Holder of the Warrant ADSs which it is then entitled to receive upon the due exercise of Warrants. Without limiting any rights
of a Holder to receive Warrant Shares on a “cashless exercise” pursuant to Section 4(d) or to receive cash payments pursuant
to Section 4(e)(i) and Section 4(m) herein, in no event shall the Company be required to net cash settle an exercise of this Warrant.

 

b)
Due Authorization. The Company represents and warrants that (a) it is duly incorporated and validly existing under the laws of
its jurisdiction of incorporation, (b) the offer and sale of the Warrants and the execution, delivery and performance of all transactions
contemplated thereby (including this Warrant) have been duly authorized by all necessary corporate action and will not result in a breach
of or constitute a default under the articles of association, bylaws or any similar document of the Company or any indenture, agreement
or instrument to which it is a party or is bound, (c) this Warrant has been duly executed and delivered by the Company and constitutes
the legal, valid, binding and enforceable obligation of the Company, (d) the Warrants will comply in all material respects with all applicable
requirements of law and (e) to the best of its knowledge, there is no litigation pending or threatened as of the date hereof in connection
with the offering of the Warrants.

 

    	31

     

    

 

c)
Reservation of Ordinary Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued
ordinary shares that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Warrant Agreement.

 

d)
Authorized Shares. The Company 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 purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such Warrant ADSs 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 ordinary shares may be listed. The Company
covenants that all Warrant ADS which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise
of the purchase rights represented by this Warrant and payment for such Warrant ADS in accordance herewith, be duly authorized, validly
issued and fully paid 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).

 

e)
Restrictive Legends; Fractional Warrants. In the event that a Warrant Certificate surrendered for transfer bears a restrictive
legend, the Warrant Agent shall not register that transfer until the Warrant Agent has received an opinion of counsel for the Company
stating that such transfer may be made and indicating whether the Warrants must also bear a restrictive legend upon that transfer. The
Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the transfer of or delivery
of a Warrant Certificate for a fraction of a Warrant. The Holder acknowledges that the Warrant ADSs 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 securities laws.

 

f)
Expense Reimbursement. The Company shall reimburse the Holder, upon the Holder’s request, for any reasonable fees charged
to the Holder by the Depositary in connection with the issuance or holding or sale of ADSs, Warrant ADSs and/or ordinary shares.

 

g)
Notices to Warrant Agent. Except as expressly set forth elsewhere in this Warrant Agreement, all notices, instructions and communications
under this Warrant Agreement shall be in writing, by overnight delivery service, first-class mail, postage prepaid, properly addressed
shall be effective upon receipt (or in the case of notice via e-mail, the notice shall be deemed delivered upon sending as long as
an automated e-mail is not generated indicating that the e-mail has not been delivered)  and shall be addressed, if to the Company,
to its address set forth beneath its signature to this Warrant Agreement, or, if to the Warrant Agent, to:

or
to such other address of which a party hereto has notified the other party; and, if to a Holder made if sent by first-class mail, postage
prepaid, or overnight delivery service, addressed to such Holder at the last address of such Holder set forth for such holder in the
Warrant Register.

h)
Governing Law. This Warrant shall be governed by and construed in accordance with the law of the State of New York.
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 and County of
New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City and
County of New York 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.

 

i)
Payment of Taxes. The Company will from time to time promptly pay all taxes and charges that may be imposed upon the Company or
the Warrant Agent in respect of the issuance or delivery of Warrant ADSs upon the exercise of Warrants, but the Company may require the
Holders to pay any transfer taxes in respect of the Warrants or such shares. The Warrant Agent may refrain from registering any transfer
of Warrants or any delivery of any Warrant ADSs unless or until the persons requesting the registration or issuance shall have paid to
the Warrant Agent for the account of the Company the amount of such tax or charge, if any, or shall have established to the reasonable
satisfaction of the Company and the Warrant Agent that such tax or charge, if any, has been paid.

 

j)
Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant
to purchase 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 Warrant ADSs or as a shareholder 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, on
the one hand, and the Holder or the beneficial owner of this Warrant, on the other hand.

 

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.

 

p)
Warrant Agency Agreement. If this Warrant is held in global form through DTC (or any successor depositary), this Warrant is issued
subject to the Warrant Agency Agreement. Without limiting any of the rights and immunities of the Warrant Agent or modifying the Warrant
Agent’s express duties and obligations under the Warrant Agreement, to the extent any provision of this Warrant conflicts
with the express provisions of the Warrant Agency Agreement, the provisions of this Warrant shall govern and be controlling.
