| | --- | ----------------------------------------------------------------------------------------------------------------------------



| | (C) | This Warrant.
| | --- | -------------

Execution and delivery of the Notice of Exercise shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Exercise
Shares, if any. This Warrant shall be deemed to have been exercised on the date the Exercise Price is received by the Company (such date, the Exercise Date).

Upon the valid exercise of this Warrant, the Company shall promptly (but in no event later than three Trading Days after the
Exercise Date) issue or cause to be issued and cause to be delivered to or upon the written order of the Holder and in such name or names as the Holder may designate, a certificate for the Exercise Shares issuable upon such exercise, free of

restrictions pursuant to Rule 144 under the Securities Act. The Company shall, upon request of the Holder, use commercially reasonable efforts to deliver Exercise Shares hereunder electronically through The Depository Trust Company or another
established clearing corporation performing similar functions if, at the time of delivery of such Warrant Shares, the Company is generally able to so deliver Ordinary Shares electronically.

The person in whose name any certificate or certificates for Exercise Shares are to be issued upon exercise of this Warrant shall
be deemed to have become the holder of record of such shares on the date on which this Warrant was surrendered and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate or certificates, except that, if the
date of such surrender and payment 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 close of business on the next succeeding date on which the stock
transfer books are open.

Subject to the final sentence of this paragraph and to the extent permitted by law, the
Companys obligations to issue and deliver Exercise Shares in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any
provision hereof, the recovery of any judgment against any person or entity or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other person or
entity of any obligation to the Company or any violation or



---

alleged violation of law by the Holder or any other person or entity, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in
connection with the issuance of Exercise Shares. The Holder shall, subject to the following proviso, have the right to pursue any 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 Exercise Shares upon exercise of this Warrant as required pursuant to the terms hereof.



| | 2.1. | ISSUANCE OF NEW WARRANTS. Upon any partial exercise of this Warrant, the Company, at its expense, will forthwith and, in any event within five
(5) Business Days, issue and deliver to the Holder a new warrant or warrants of like tenor, registered in the name of the Holder, exercisable, in the aggregate, for the balance of the number of Ordinary Shares remaining available for purchase
under this Warrant.

involved in the issuance of, and the preparation and delivery of certificates (if applicable) representing, (i) any Exercise Shares purchased upon exercise of this Warrant and/or (ii) new or replacement warrants in the Holders name
or the name of any transferee of all or any portion of this Warrant; provided, however,that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance, delivery or registration
of any certificates for Exercise Shares or Warrants in a name other than that of the Holder. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Exercise Shares
upon exercise hereof.

|3. | COVENANTS OF THE COMPANY.
|-- | -------------------------



| | 3.1. | COVENANTS AS TO EXERCISE SHARES. The Company covenants and agrees that all Exercise Shares that may be issued upon the exercise of the rights
represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid up and free from all taxes, liens and charges with respect to the issuance thereof. The Company further covenants and agrees that the Company will at all
times during the Exercise Period, have authorized and reserved, free from preemptive rights, a sufficient number of Ordinary Shares to provide for the exercise of the rights represented by this Warrant. If at any time during the Exercise Period the
number of authorized but unissued Ordinary Shares shall not be sufficient to permit exercise of this Warrant, the Company will use its commercially reasonable best efforts to take such corporate action in compliance with applicable law as may, in
the opinion of its counsel, be necessary to increase its authorized but unissued Ordinary Shares to such number of shares as shall be sufficient for such purposes.
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3.2. | NOTICES OF RECORD DATE AND CERTAIN OTHER EVENTS. In the event of any taking by the Company of a record of the holders of any class of securities for
the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, the Company shall mail to the Holder, at least fifteen (15) days prior to the date on which any such record is to be taken for the
purpose of such dividend or distribution, a notice specifying such date. In the event of any voluntary dissolution, liquidation or winding up of the Company, the Company shall mail to the Holder, at least fifteen (15) days prior to the date of
the occurrence of any such event, a notice specifying such date. In the event the Company authorizes or approves, enters into any agreement contemplating, or solicits stockholder approval for any Fundamental Transaction, as defined in
Section 6 herein, the Company shall mail to the Holder, at least fifteen (15) days prior to the date of the occurrence of such event, a notice specifying such date. Notwithstanding the foregoing, the failure to deliver such notice
or any defect therein shall not affect the validity of the corporate action required to be described in such notice.
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4. | ADJUSTMENT OF EXERCISE PRICE AND SHARES.
|-- | ----------------------------------------



---

The Exercise Price and number of Exercise Shares issuable upon exercise of this
Warrant are subject to adjustment from time to time as set forth in this Section 4.



| | (D) | If the Company, at any time while this Warrant is outstanding, (i) pays a dividend on its Ordinary Shares or otherwise makes a distribution on any class
of capital stock that is payable in Ordinary Shares, (ii) subdivides outstanding Ordinary Shares into a larger number of shares, or (iii) combines outstanding Ordinary Shares into a smaller number of shares, then in each such case the
number of Exercise Shares issuable upon exercise of this Warrant shall be proportionately adjusted to reflect the distribution, subdivision or combination and the Exercise Price shall be multiplied by a fraction of which the numerator shall be the
number of Ordinary Shares outstanding immediately before such event and of which the denominator shall be the number of Ordinary Shares outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall
become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective
immediately after the effective date of such subdivision or combination.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (E) | If the Company, at any time while this Warrant is outstanding, distributes to holders of Ordinary Shares (i) evidences of its indebtedness, (ii) any
security (other than a distribution of Ordinary Shares covered by the preceding paragraph), (iii) rights or warrants to subscribe for or purchase any security, or (iv) any other asset (in each case, Distributed
Property),then in each such case the Holder shall be entitled upon exercise of this Warrant for the purchase of any or all of the Exercise Shares, to receive the amount of Distributed Property which would have been payable to
the Holder had such Holder been the holder of such Exercise Shares on the record date for the determination of stockholders entitled to such Distributed Property. The Company will at all times set aside in escrow and keep available for distribution
to such holder upon exercise of this Warrant a portion of the Distributed Property to satisfy the distribution to which such Holder is entitled pursuant to the preceding sentence.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (F) | Upon the occurrence of each adjustment pursuant to this Section 4, the Company at its expense will, at the written request of the Holder, promptly
compute such adjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Exercise Shares or other securities
issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the Company will promptly deliver a copy
of each such certificate to the Holder and to the Companys transfer agent.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5. | FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All
Exercise Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in
the issuance of a fractional share, the number of Exercise Shares to be issued will be rounded down to the nearest whole share.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|6. | FUNDAMENTAL TRANSACTIONS. If any capital reorganization, reclassification of the share capital of the Company, consolidation or merger of the Company
with another entity in which the Company is not the survivor or the shareholders of the Company
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | immediately prior to such transaction own less than 50% of the voting power of the surviving entity immediately after such transaction, or sale, transfer or other disposition of all or
substantially all of the Companys assets to another entity shall be effected (any such transaction being hereinafter referred to as a Fundamental Transaction),then the Company shall use its commercially
reasonable efforts to ensure that lawful and adequate provision shall be made whereby the Holder shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions herein specified and in lieu of the Exercise
Shares immediately theretofore issuable upon exercise of this Warrant, such shares of stock, securities or assets as would have been issuable or payable with respect to or in exchange for a number of Exercise Shares equal to the number of Exercise
Shares immediately theretofore issuable upon exercise of this Warrant, had such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition not taken place, and in any such case appropriate provision shall be made
with respect to the rights and interests of the Holder to the end that the provisions hereof (including, without limitation, provision for adjustment of the Exercise Price) shall thereafter be applicable, as nearly equivalent as may be practicable
in relation to any share of stock, securities or assets thereafter deliverable upon the exercise thereof. The Company shall not effect any such consolidation, merger, sale, transfer or other disposition unless prior to or simultaneously with the
consummation thereof the successor entity (if other than the Company) resulting from such consolidation or merger, or the entity purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume the obligation to
deliver to the Holder, at the last address of the Holder appearing on the books of the Company, such shares of stock, securities or assets as, in accordance with the foregoing provisions, the Holder may be entitled to purchase, and the other
obligations under this Warrant. The provisions of this Section 6 shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales, transfers or other dispositions, each of which transactions shall also
constitute a Fundamental Transaction.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7. | NO SHAREHOLDER RIGHTS. Other than as provided in Section 3.2 or otherwise herein, this Warrant in and of itself shall not entitle the
Holder to any voting rights or other rights as a shareholder of the Company.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|8. | TRANSFER OF WARRANT. Subject to applicable laws and the restrictions on transfer set forth in Section 4.1 of the Purchase Agreement, this Warrant
and all rights hereunder are transferable, by the Holder in person or by duly authorized attorney, upon delivery of this Warrant and the form of assignment attached hereto to any transferee designated by Holder. The transferee shall sign an
investment letter in form and substance reasonably satisfactory to the Company and its counsel. Any purported transfer of all or any portion of this Warrant in violation of the provisions of this Warrant or Section 4.1 of the Purchase Agreement
shall be null and void.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9. | LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnity
or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed. Any such new
Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|10. | NOTICES. Any notice, request or other document required or permitted to be given or delivered hereunder shall be delivered in accordance with the
notice provisions of the Purchase Agreement.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|11. | ACCEPTANCE. Receipt of this Warrant by the Holder shall constitute acceptance of
|--- | --------------------------------------------------------------------------------



---

| | and agreement to all of the terms and conditions contained herein.
| | ------------------------------------------------------------------



|12. | GOVERNING LAW. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by and construed
and enforced in accordance with the internal laws of the State of California, without regard to the principles of conflicts of law thereof. Each of the Company and the Holder hereby irrevocably waives personal service of process and consents to
process being served in any 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 the Purchase Agreement 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 manner permitted by law.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|13. | AMENDMENT OR WAIVER. Any term of this Warrant may be amended or waived (either generally or in a particular instance and either retroactively or
prospectively) with the written consent of the Company and the Holder. No waiver of any default with respect to any provision, condition or requirement of this Warrant shall be deemed to be a continuing waiver in the future or a waiver of any
subsequent default or a waiver of any other provision, condition or requirement hereof.
