Warrantholder’s election to exercise the number of Warrants and the method of exercise specified therein, properly completed and duly executed by such Warrantholder, in the form attached hereto as Exhibit B (an “Exercise
Notice”), and the Warrant Agent will deliver such Exercise Notice to the Company as promptly as practicable; and 

(iii)    in all cases, (x) pay to the Warrant Agent an amount equal to the product of (A) the
Exercise Price and (B) the total number of Ordinary Shares for which such Definitive Warrants are exercisable (the “Aggregate Exercise Price”) together with any payment for transfer taxes as set forth in
Section 3.5. if and as applicable, in any combination of the following elected by such Warrantholder: (1) certified bank check or official bank check in New York Clearing House funds payable to the order of the Warrant
Agent and delivered to the Warrant Agent at the Corporate Agency Office, or (2) wire transfer in immediately available funds to an account specified in writing by the Company to the Warrant Agent and such Warrantholder in accordance with
Section 11.1(b); or (y) in lieu of making a cash payment, instruct the Company to withhold a number of Ordinary Shares issuable upon exercise of the Definitive Warrants being exercised with an aggregate Fair Market
Value as of the Exercise Date equal to the Aggregate Exercise Price, which shall be treated as the surrender of the Definitive Warrants being exercised in return for the issue of the relevant number of Ordinary Shares net of such withholding (the
“Cashless Exercise (by way of Net Issue)”). Each Ordinary Share issuable by the Company shall be issued at nominal value and no share premium shall be payable thereon. In such circumstances, the Company shall procure that the
nominal value of each Ordinary Share shall be paid up in cash at the time of issue of such Ordinary Shares without recourse to the relevant Warrantholder. 

  
 12 












 Any attempt to exercise Warrants not in compliance with this Agreement shall be null and void ab
initio, and the Company and the Warrant Agent shall not give effect in their respective records to any such attempted exercise of Warrants. 

(c)    Cashless Exercise (by way of Net Issue). Upon the Warrant Agent’s receipt of an Exercise Notice and
instructions to withhold a number of Ordinary Shares pursuant to Section 3.2(b)(iii)(y), the Company shall, as promptly as practicable, determine (or to the extent applicable pursuant to clause (b) of the definition of
Fair Market Value, cause the Independent Financial Expert to determine) the Fair Market Value of the Ordinary Shares and provide the Warrant Agent and Warrantholder with a calculation of the number of Ordinary Shares required to be withheld pursuant
to Section 3.2(b)(iii)(y), which the Warrant Agent shall rely upon to update the Warrant Register. The Warrant Agent shall have no obligation under this Agreement to perform or verify such calculation or otherwise determine
whether such calculation is correct. 
 (d)    Partial Exercise. If fewer than all the Definitive Warrants
represented by a Warrant Certificate are exercised, such Warrant Certificate shall be surrendered and a new Warrant Certificate of the same tenor and for the number of Definitive Warrants which were not exercised shall be executed by the Company.
The Warrant Agent shall countersign the new Warrant Certificate, registered in such name or names, subject to the provisions of Section 8 regarding registration of transfer and payment of governmental charges in respect
thereof, as may be directed in writing by the Warrantholder, and shall deliver the new Warrant Certificate to the Person or Persons in whose name such new Warrant Certificate is so registered. The Company, whenever required by the Warrant Agent,
will supply the Warrant Agent with Warrant Certificates duly executed on behalf of the Company for such purpose. 

(e)    Global Warrants. In the case of Warrants represented by a Global Warrant Certificate, the Warrants shall be
exercisable, at any time or from time to time during the Exercise Period, in accordance with the applicable practices and procedures of the Depositary and the relevant Agent Member. Following any such exercise, the number of Warrants represented by
the applicable Global Warrant Certificate shall be reduced in accordance with the applicable procedures of the Depositary, whether or not an adjustment is made to Annex A to such Global Warrant Certificate, so that the number of Warrants represented
thereby will be equal to the number of Warrants theretofore represented by such Global Warrant Certificate less the number of Warrants then exercised. An Agent Member, and any Person authorized by such Agent Member, may, without the consent of the
Warrant Agent or any other Person, on its own behalf and on behalf of the owner of a beneficial interest in the Global Warrant for which it is acting, enforce this Agreement and the Global Warrant, including its or such beneficial owner’s right
to exercise and receive beneficial ownership of Ordinary Shares issuable upon exercise of the Global Warrant, and may institute and maintain any suit, action or proceeding against the Company to enforce its rights in respect thereof. In connection
with (i) settlement pursuant to Section 3.2(b)(iii)(x), the Exercise Price in respect of the exercise of a Global Warrant shall be paid, and (ii) settlement pursuant to
Section 3.2(b)(iii)(y), the election to withhold a number of Ordinary Shares issuable upon exercise of the Global Warrants being exercised with an aggregate Fair Market Value as of the Exercise Date equal to the Aggregate
Exercise Price shall be made, in each case, in accordance with the applicable practices and procedures of the Depositary and its Agent Members. 

(f)    Issuance of Ordinary Shares. 

  
 13 












 (i)    Upon due exercise of Global Warrants in
accordance with the foregoing provisions of Section 3.2(e), Ordinary Shares issuable upon such exercise shall be issued and delivered in accordance with the applicable practices and procedures of the Depositary. The Company
shall use commercially reasonable efforts to cause the transfer agent of the Company to cooperate with the Depositary and the applicable Agent Member in order to effect the issuance and delivery of Ordinary Shares as promptly as practicable in
accordance with such practices and procedures. 
 (ii)    Upon due exercise of Definitive Warrants in
accordance with the foregoing provisions of Section 3.2(b), Section 3.2(c), Section 3.2(d) or Section 3.3 or
Section 5.1, as applicable, the Company shall cause the transfer agent of the Company, as promptly as practicable but in any event no later than four (4) Business Days after the Exercise Date, to cooperate with the
Agent Member designated by the Warrantholder on the Exercise Notice in order that the Ordinary Shares will be issued fully paid (at least as to one-quarter nominal value per Ordinary Share), delivered and
credited to the account of the Agent Member at the Depositary for the benefit of the Warrantholder through the Deposit/Withdrawal at Custodian (DWAC) function of the Depositary or such other function as may be adopted by the Depositary for that
purpose. Notwithstanding the foregoing, if. at or prior to the time of the exercise of any Definitive Warrant, the Depositary notifies the Company in writing that it is unwilling or unable to continue as Depositary for the Ordinary Shares issuable
upon exercise of such Definitive Warrant or if at any time the Depositary has ceased or ceases to be a “clearing agency” registered under the Exchange Act (and notifies the Company in writing of such cessation) and. in each such case, a
successor Depositary is not appointed by the Company within ninety (90) days of such notice, the Company shall issue the Ordinary Shares fully paid (at least as to one-quarter nominal value per Ordinary
Share) in such name or names as indicated on the Exercise Notice, provided the Warrantholder shall have furnished the Company with the appropriate tax identification information and, if the Ordinary Shares are to be issued in the name of any Person
other than the Warrantholder (a “Nominee”), evidence of the payment of any required transfer or similar tax shall have been furnished to the Company. The Ordinary Shares shall be issued by the registration of the issuance in the
name of the Warrantholder or its Nominee in the register of members of the Company. Where the Company determines, in accordance with the Articles of Association, that certificates will be issued for the Ordinary Shares, the Company shall cause the
certificates representing the Ordinary Shares to be physically delivered to the address specified in the Exercise Notice. The Company shall cause the Ordinary Shares to be issued and delivered as aforesaid, as promptly as practicable but in any
event no later than four (4) Business Days after the Exercise Date. 
 (g)    Time of Exercise. Each
exercise of a Warrant shall be deemed to have been effected immediately prior to the Close of Business on the first (1st) day on which each of the following has occurred (the “Exercise Date”): (i) in the case of the exercise of
Global Warrants, the date on which all actions required for such exercise, including, if applicable, payment of the Exercise Price therefor, in accordance with the applicable practices and procedures of the Depositary have been taken; and
(ii) in the case of the exercise of Definitive Warrants, (x) if the Definitive Warrant is represented by a Warrant Certificate, the Warrant Certificate representing such Definitive Warrant has been surrendered for exercise; (y) an
Exercise Notice has been duly 

  
 14 












 
executed by the Warrantholder and delivered to the Warrant Agent as provided in Section 3.2(b); and (z) if applicable, payment has been made to the Warrant Agent as
provided in Section 3.2(b) (unless such surrender, delivery and payment (if applicable) occur after Close of Business on a Business Day or on a date that is not a Business Day, in which event the Exercise Date shall be the
next following Business Day). On the Exercise Date, the exercising Warrantholder shall, as between such Person and the Company, be deemed to be and entitled to all rights of the holder or record of such Ordinary Shares then issued. For the avoidance
of doubt, Warrants do not entitle the Warrantholder or the owner of any beneficial interest in the Warrants to any voting rights or other rights as a holder of Ordinary Shares prior to the applicable Exercise Date. 

(h)    Expiration of Warrants. The Warrants, to the extent not exercised prior thereto, shall automatically expire,
terminate and become void as of 5:01 p.m. Eastern Time on the Expiration Date. No further action of any Person (including by. or on behalf of. any Warrantholder, the Company or the Warrant Agent) shall be required to effectuate the expiration of
Warrants pursuant to this Section 3.2(h). 
 3.3.    Reserved. 

3.4.    Funds; Application of Funds Upon Exercise of Warrants. 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 in trust 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 Agreement, the Funds shall be uninvested. The Warrant Agent shall promptly deliver and pay to the Company all funds received by it upon the
exercise of any Warrants by bank wire transfer to an account designated by the Company or as the Warrant Agent otherwise may be directed in writing by the Company. 

3.5.    Payment of Taxes. The Company shall pay any and all United Kingdom stamp duty or stamp duty reserve tax
that is payable in respect of the issue or delivery of Ordinary Shares to the exercising Warrantholder on exercise of Warrants pursuant hereto; provided that, as a condition to the exercise of any Warrant, the exercising Warrantholder shall
pay to the Company a sum sufficient to cover any documentary, stamp or similar issue or transfer taxes due because such Warrantholder requests Ordinary Shares to be issued in a name other than the name of the Warrantholder, and the Company may
refuse to deliver any such Ordinary Shares until it receives a sum sufficient to pay such taxes. The Warrant Agent shall not have any duty or obligation to take any action under any section of this Agreement that requires the payment of taxes and/or
charges unless and until it is satisfied that all such payments have been made. 
 3.6.    Surrender of
Certificates. Any Warrant Certificate surrendered for exercise shall be surrendered to the Warrant Agent at the office of the Warrant Agent designated for such purpose and, if surrendered to the Company, be delivered by the Company to the
Warrant Agent. All Warrant Certificates surrendered or so delivered to the Warrant Agent shall be promptly cancelled by the Warrant Agent and shall not be reissued by the Company, and the Warrant Agent shall deliver its certificate of cancellation
to the Company. Upon request of the Company, the Warrant Agent shall destroy such cancelled Warrant Certificates and deliver its certificate of destruction to the Company. 

  
 15 












 3.7.    Shares Issuable. The number of Ordinary Shares
“obtainable upon exercise” or “issuable upon exercise” of a Warrant at any time shall be the number of Ordinary Shares for which such Warrant is then exercisable. The number of Ordinary Shares “for which each Warrant is
exercisable” shall be one (1) share, subject to adjustment as provided in Section 4.1. 
  

	4.	 Adjustments. 



4.1.    Adjustments. In order to prevent dilution of the rights granted under the Warrants, the Exercise Price
shall be subject to adjustment from time to time as provided in this Section 4.1 and the number of Ordinary Shares obtainable upon exercise of the Warrants shall be subject to adjustment from time to time as provided in
this Section 4.1 (in each case, after taking into consideration any prior adjustments pursuant to this Section 4.1) provided that no single event shall give rise to an adjustment under more
than one subsection of this Section 4.1. 
 (a)    Subdivisions and Combinations. 

(i)    In the event the Company shall, at any time or from time to time after the Effective Date while the
Warrants remain outstanding and unexpired in whole or in part, effect a subdivision (by any stock split or otherwise) of the outstanding Ordinary Shares into a greater number of Ordinary Shares (other than (x) a stock split effected by means of
a stock dividend or stock distribution to which Section 4.1(b) applies or (y) a subdivision upon a transaction to which Section 5 applies), then and in each such event the Exercise Price then
in effect shall be decreased by multiplying the Exercise Price immediately in effect prior thereto by a fraction (i) the numerator of which shall be the total number of Ordinary Shares issued and outstanding immediately prior to such
subdivision and (ii) the denominator of which shall be the number of Ordinary Shares issued and outstanding immediately prior to such subdivision plus the number of Ordinary Shares issuable as a result of such subdivision. Conversely, if the
Company shall, at any time or from time to time after the Effective Date while the Warrants remain outstanding and unexpired in whole or in part effect a combination (by any reverse stock split or otherwise) of the outstanding Ordinary Shares into a
smaller number of Ordinary Shares (other than a combination upon a transaction to which Section 5 applies), then and in each such event the Exercise Price then in effect shall be increased by multiplying the Exercise Price
immediately in effect prior thereto by a fraction (i) the numerator of which shall be the total number of Ordinary Shares issued and outstanding immediately prior to such combination and (ii) the denominator of which shall be the number of
Ordinary Shares issued and outstanding immediately prior to such combination less the number of Ordinary Shares reduced as a result of such combination. 

(ii)    Subject to Section 4.1(f)(iii) and
Section 4.1(f)(iv), any adjustment under this Section 4.1(a) shall become effective immediately at the Open of Business on the day after the date upon which such subdivision or combination becomes
effective. 
 (b)    Ordinary Share Dividends. 

(i)    In the event the Company shall, at any time or from time to time after the Effective Date while the
Warrants remain outstanding and unexpired in whole or 

  
 16 












 
in part, pay or make to the holders of its outstanding Ordinary Shares, or shall fix a Record Date for the determination of holders of its Ordinary Shares to receive, a dividend or distribution
payable in Ordinary Shares, or otherwise pay or make, or shall fix a Record Date for the determination of holders of its Ordinary Shares to receive, a dividend or other distribution on any class of its share capital payable in Ordinary Shares, other
than a dividend or distribution upon a transaction to which Section 5 applies, then and in each such event the Exercise Price in effect on the Record Date for such dividend or distribution shall be decreased by multiplying
such Exercise Price by a fraction (not to be greater than one (1)), (A) the numerator of which shall be the total number of Ordinary Shares issued and outstanding immediately prior to such dividend or distribution and (B) the denominator of
which shall be the number of Ordinary Shares issued and outstanding immediately prior to such dividend or distribution plus the number of Ordinary Shares issuable in payment of such dividend or distribution. 

(ii)    Subject to Section 4.1(f)(ii),
Section 4.1(f)(iii) and Section 4.1(f)(iv), any adjustment under this Section 4.1(b) shall become effective immediately at the Open of Business on the day after the Record
Date for such dividend or distribution. 
 (c)    Repurchases. 

(i)    In the event the Company shall, at any time or from time to time after the Effective Date while the
Warrants remain outstanding and unexpired in whole or in part, offer to repurchase Ordinary Shares at a price per share that is greater than the Fair Market Value of such Ordinary Shares as of the tenth (10th) Trading Day immediately following the
date on which such offer to repurchase is consummated (other than a repurchase upon a transaction to which Section 5 applies) on the date on which such offer is consummated (an “Above FMV Repurchase”), then
the Exercise Price in effect on the date of the consummation of the Above FMV Repurchase shall be decreased to a price determined in accordance with the following formula: 

CPA2 = CPA1 * (FMV-P) ÷ FMV 
 For purposes of the foregoing formula, the following definitions shall apply: 

 

	 	•	 	 “CPA2” shall mean the Exercise Price in effect
immediately after the adjustment provided in this Section 4. l(c)(i); 


  

	 	•	 	 “CPA1” shall mean the Exercise Price in effect
immediately prior to such Above FMV Repurchase; 


  

	 	•	 	 “FMV” shall mean the Fair Market Value of the total number of Ordinary Shares outstanding prior to the
consummation of such Above FMV Repurchase, calculated based on the Fair Market Value of one Ordinary Share on the Business Day after the tenth (10th) Trading Day immediately following the date on which such Above FMV Repurchase is consummated; and




  
 17 













	 	•	 	 “P” shall mean the amount by which the Fair Market Value of all consideration paid or payable for
Ordinary Shares repurchased or redeemed in any Above FMV Repurchase exceeds the aggregate Fair Market Value for such Ordinary Shares on the Business Day after the tenth (10th) Trading Day immediately following the date on which such Above FMV
Repurchase is consummated. 


 (ii)    Subject to
Section 4.1(f)(iii) and Section 4.1(f)(iv), any adjustment under this Section 4.1(c) shall be effective as of the Open of Business on the Business Day immediately
following the date on which such Above FMV Repurchase is consummated. 
 (d)    Property Dividends. 

(i)    In the event the Company shall, at any time or from time to time after the Effective Date while the
Warrants remain outstanding and unexpired in whole or in part, make or issue, or shall fix a Record Date for the determination of holders of its Ordinary Shares to receive, a Property Dividend, then and in each such event the Exercise Price in
effect on the Record Date for such Property Dividend shall be decreased to a price determined in accordance with the following formula: 

EP2 = EP1 * (FMV - D)
÷ FMV 
 For purposes of the foregoing formula, the following definitions shall apply: 

 

	 	•	 	 “EP2” shall mean the Exercise Price in effect
immediately after the adjustment provided in this Section 4.1 (d)(i); 


  

	 	•	 	 “EP1” shall mean the Exercise Price in effect
on the Record Date for such Property Dividend; 


  

	 	•	 	 “FMV” shall mean the Fair Market Value of one Ordinary Share on the Record Date for such Property
Dividend; and 


  

	 	•	 	 “D” shall mean the Fair Market Value of such Property Dividend made per Ordinary Share as of the Record
Date for such Property Dividend. 


 (ii)    Subject to
Section 4.1(f)(ii), Section 4.1(f)(iii) and Section 4.1(f)(iv), any adjustment under this Section 4.1(d) shall become effective immediately at
the Open of Business on the day after the Record Date for such Property Dividend. 
 (e)    Rights Offerings.

 (i)    If the Company issues, or shall fix a Record Date for the determination of holders of its
Ordinary Shares to receive, as a dividend or distribution any right to the Shareholders permitting the Shareholders to subscribe for additional Ordinary Shares pursuant to a rights offering at a price per Ordinary Share less than the Fair Market
Value thereof as of the Trading Day immediately preceding the announcement date of the Rights Offering (a “Rights Offering”), then the Exercise Price in effect at the Open of Business on the Business Day immediately following the
date on which such Rights 

  
 18 












 
Offering is consummated shall be decreased to a price determined in accordance with the following formula: 

EP2 = EP1 * (O + Y) ÷
(O + X) 
  

	 	•	 	 “EP2” shall mean the Exercise Price in effect
immediately after the adjustment provided in this Section 4.1(e)(i); 


  

	 	•	 	 “EP1” shall mean the Exercise Price in effect
immediately before the adjustment provided in this Section 4.1(e)(i); 


  

	 	•	 	 “O” shall mean the number of Ordinary Shares outstanding immediately before the consummation of the
Rights Offering; 


  

	 	•	 	 “X” shall mean the number of Ordinary Shares issuable upon exercise of such rights pursuant to the
Rights Offering; and 


  

	 	•	 	 “Y” shall mean the number of Ordinary Shares equal to the aggregate price payable for the Ordinary
Shares in the Rights Offering divided by the Fair Market Value of one Ordinary Share as of the Trading Day immediately preceding the announcement date of the Rights Offering. 



For purposes of this Section 4.1(c)(i), if the applicable Rights Offering is for securities convertible into or
exercisable for Ordinary Shares, in determining the price payable for Ordinary Shares, there shall be taken into account all consideration received for such rights, as well as any additional amount payable upon exercise or conversion. 

(ii)    Subject to Section 4.1(f)(iii) and Section 4.
l(f)(iv), any adjustment under this Section 4.1(e) shall be effective as of the Open of Business on the Business Day immediately following the date on which such Rights Offering is consummated. 

(f)    Other Provisions Applicable to Adjustments. The following provisions shall be applicable to
the making of adjustments to the Exercise Price and the number of Ordinary Shares for which each Warrant is exercisable under this Section 4.1: 

(i)    When Adjustments Are to be Made. The adjustments required by Sections 4.1(a),
4.1(b), 4.1(c), 4.1(d) and 4.1(e) shall be made whenever and as often as any specified event requiring an adjustment shall occur. 

(ii)    Deferral of Issuance Upon Exercise. Notwithstanding anything in this Agreement to the
contrary, in any case in which this Section 4.1 shall require that a decrease in the Exercise Price be made effective prior to the occurrence of a specified event (which shall be deemed to mean, for purposes of
Section 4.1(b), 4.1(d) and 4.1(e). the dividend or distribution with respect to which a Record Date may be fixed) and any Warrant is exercised after the time at which the adjustment became effective but prior
to the occurrence of such specified event and, in connection therewith, Section 4.1(f) shall require a corresponding increase in the number of Ordinary Shares for which each Warrant is exercisable, the Company may elect to
defer until the occurrence of such 

  
 19 












 
specified event (A) the issuance to the Warrantholders of, and the registration of such Warrantholder (or other Person) as the record holder of, the Ordinary Shares over and above the
Ordinary Shares issuable upon such exercise on the basis of the number of Ordinary Shares obtainable upon exercise of such Warrant(s) immediately prior to such adjustment and to require payment in respect of such number of shares the issuance of
which is not deferred on the basis of the Exercise Price in effect immediately prior to such adjustment and (B) the corresponding reduction in the Exercise Price. 

(iii)    Notwithstanding anything in this Agreement to the contrary, in the event that an adjustment is
made pursuant to this Section 4.1 and either (x) the underlying event requiring such adjustment does not occur, including, in the case of any adjustment in respect of any dividend or distribution or the fixing of a
Record Date with respect thereto, where the Board publicly announces its decision not to pay or make such dividend or distribution, or (y) in the case of a Rights Offering pursuant to Section 4.1(e), upon the
expiration or termination of any unexercised right (or portion thereof) or any unconverted or unexchanged security that is convertible into or exercisable or exchangeable for Ordinary Shares, in each case, referred to in
Section 4.1(e), the Exercise Price and the number of Ordinary Shares for which a Warrant is exercisable shall be readjusted retroactively to the date of the original adjustment, to be the Exercise Price and the number of
Ordinary Shares for which a Warrant is exercisable that would then be in effect had the applicable adjustment not been made. 

(iv)    Notwithstanding anything in this Agreement to the contrary, no adjustment under this
Section 4.1 need be made to the Exercise Price unless such adjustment would require an increase or decrease of at least one percent (1.0%) of the Exercise Price then in effect. Any lesser adjustment shall be carried forward
and shall be made at the time of and together with the next subsequent adjustment, if any, which, together with any adjustment or adjustments so carried forward, shall amount to an increase or decrease of at least one percent (1.0%) of the Exercise
Price. 
 (g)    Adjustment to Shares Obtainable Upon Exercise. Subject to
Section 4.1(f)(ii) and Section 4. l(f)(iii), whenever the Exercise Price is adjusted as provided in Sections 4.1(a), 4.1(b), 4.1(c), 4.1(d) or 4.1(e) the number
of Ordinary Shares for which a Warrant is exercisable shall simultaneously be adjusted by multiplying such number of Ordinary Shares for which a Warrant is exercisable immediately prior to such adjustment by a fraction, the numerator of which shall
be the Exercise Price immediately prior to such adjustment, and the denominator of which shall be the Exercise Price immediately thereafter. 

(h)    Notice of Adjustment. Upon the occurrence of each adjustment of the Exercise Price or the number of
Ordinary Shares for which a Warrant is exercisable pursuant to this Section 4.1, the Company at its expense shall promptly: 

(i)    compute such adjustment in accordance with the terms hereof; 

(ii)    after such adjustment becomes effective, deliver or communicate to all Warrantholders and owners of
a beneficial interest in a Global Warrant, in accordance with Section 11.1(b), a notice setting forth such adjustment (including the kind and amount 

  
 20 












 
of securities, cash or other property for which the Warrants shall be exercisable and the Exercise Price) and setting forth a reasonably detailed statement of the facts requiring such adjustment;
provided that the failure of the Company to deliver such notice shall not affect the validity of the relevant adjustments or the events giving rise to such adjustments; provided, further. that, (x) the failure of the Company to
deliver such notice shall not limit the Company’s obligation to effectuate such adjustment in accordance with this Section 4.1 and (y) if the Company fails to deliver such notice after such adjustment becomes
effective, the Company shall promptly provide such notice to any Warrantholder upon its request; and 

(iii)    deliver to the Warrant Agent a certificate of the Chief Executive Officer, Chief Financial Officer
or Treasurer of the Company setting forth the Exercise Price and the number of Ordinary Shares for which each Warrant is exercisable after such adjustment and setting forth a reasonably detailed statement of the facts requiring such adjustment and
the computation by which such adjustment was made (including a description of the basis on which the fair market value of any evidences of indebtedness, shares of capital stock, securities or other assets or consideration used in the computation was
determined). As provided in Section 10.1, the Warrant Agent (x) shall be entitled to rely on such certificate, (y) shall be under no duty, liability or responsibility with respect to any such certificate, except
to exhibit the same from time to time to any Warrantholder desiring an inspection thereof during reasonable business hours and (z) shall not be deemed to have knowledge of any such adjustment or any such facts requiring any such adjustment
unless and until it shall have received such certificate. 
 (i)    Statement on Warrant Certificates.
Irrespective of any adjustment in the Exercise Price or amount or kind of shares for which the Warrants are exercisable, Warrant Certificates theretofore or thereafter issued may continue to express the same Exercise Price initially applicable or
amount or kind of shares initially issuable upon exercise of the Warrants evidenced thereby pursuant to this Agreement. 

4.2.    Fractional Interest. The Company shall not be required upon the exercise of any Warrant to issue any
fractional shares (or scrip representing fractional shares). In the event a Warrant becomes exercisable for fractional Ordinary Shares, the number of Ordinary Shares issuable upon exercise thereof will be rounded (i) up to the next higher whole
Ordinary Share if the fraction is equal to or greater than 1/2 and (ii) down to the next lower whole Ordinary Share if the fraction is less than 1/2. If Warrant Certificates evidencing more than one (1) Warrant shall be presented for
exercise at the same time by the same Warrantholder, the number of full Ordinary Shares which shall be issuable upon such exercise thereof shall be computed on the basis of the aggregate number of Warrants so to be exercised. The Warrantholders, and
any owners of a beneficial interest in a Global Warrant, by their acceptance of the Warrant Certificates, expressly waive their right to receive any fraction of an Ordinary Share, a share certificate representing a fraction of an Ordinary Share or
any cash consideration in lieu of a fractional Ordinary Share if such fractional share is rounded down. 
 4.3.    No
Other Adjustments. In each case except in accordance with Section 4.1, the applicable Exercise Price and the number of Ordinary Shares obtainable upon exercise of any Warrant will not be adjusted for the issuance of
Ordinary Shares or any securities convertible into or exchangeable for Ordinary Shares or carrying the right to purchase any of the foregoing, including: 

  
 21 












 (a)    upon the issuance of any other securities by the Company on or
after the Effective Date, or upon the issuance of Ordinary Shares upon the exercise of any such securities; 

(b)    upon the issuance of any Ordinary Shares or other securities or any payments pursuant to the any other equity
incentive plan of the Company; 
 (c)    upon the issuance of any Ordinary Shares pursuant to the exercise of the
Warrants, the Tranche 1 Warrants or the Tranche 2 Warrants; or 
 (d)    upon the issuance of any Ordinary Shares or
other securities of the Company in connection with a business acquisition transaction (except as expressly set forth in Section 4.1). 
  

	5.	 Fundamental Transaction; Organic Changes. 



5.1.    Fundamental Transaction. 

(a)    In the event the Company shall, at any time or from time to time after the Effective Date while the Warrants remain
outstanding and unexpired in whole or in part, consummate a Fundamental Transaction, each Warrantholder shall be entitled, following consummation of the Fundamental Transaction, upon surrender and delivery of the related Warrant Certificate to the
Warrant Agent (or. if applicable, on the records of the Depositary to an account of the Warrant Agent at the Depositary designated for such purposes in writing by the Warrant Agent to the Depositary from time to time), for each Warrant held by such
Warrantholder to exercise such Warrant to acquire the Fundamental Transaction Consideration multiplied by the Warrant Share Number; provided, that if the Fundamental Transaction Consideration consists solely of Cash Consideration, following
the consummation of the Fundamental Transaction, such Warrantholder shall be entitled to receive an amount of cash equal to the product of (A) the Warrant Share Number and (B) the amount, if any, by which (x) the Cash Consideration
exceeds (y) the Exercise Price, and upon such Warrantholder’s receipt of such cash (if any) in respect of such Warrant, such Warrant shall be deemed to have been exercised in full and cancelled. 

(b)    As used in Section 5.1, the terms set forth below shall have the respective meanings set
forth in this Section 5.1(b). 
 (i)    “Cash Consideration”

Fundamental Transaction. 
 (ii)    “Exercise Price” means the Exercise Price in effect
immediately prior to consummation of the Fundamental Transaction. 
 (iii)    “Fundamental
Transaction Consideration” means the cash, stock, securities or other assets or property (or any combination thereof) that a holder of Ordinary Shares receives or is entitled to receive with respect to or in exchange for each Ordinary Share
held by such holder upon consummation of a Fundamental Transaction. 

  
 22 












 (iv)    “Warrant Share Number” means
the number of Ordinary Shares for which a Warrant is exercisable immediately prior to the consummation of the Fundamental Transaction. 

(c)    If in any Fundamental Transaction a holder of Ordinary Shares shall be entitled to make an election to receive Cash
Consideration. Equity Consideration or Other Consideration, or a combination thereof, with respect to each Ordinary Share held by such holder, for purposes of this Section 5.1, the holder shall be deemed to receive or be
entitled to receive for each such Ordinary Share the aggregate amount of Cash Consideration. Equity Consideration or Other Consideration, or combination thereof, received or receivable by all holders of Ordinary Shares divided by the total number of
Ordinary Shares outstanding immediately prior to consummation of the Fundamental Transaction. 
 (d)    The Company
shall not effect any Fundamental Transaction unless, prior to the consummation thereof, the surviving Person (if other than the Company) resulting from such Fundamental Transaction, shall assume, by written instrument substantially similar in form
and substance to this Agreement in all material respects (including with respect to the provisions of this Section 5) and the obligation to distribute any warrants or make any cash payments to the Warrantholders in
accordance with this Section 5.1. The provisions of this Section 5.1 shall similarly apply to successive Fundamental Transactions. 

(e)    The provisions of this Section 5.1 are subject, in all cases, to any applicable
requirements under the Securities Act and the Exchange Act and the respective rules and regulations promulgated thereunder. 

5.2.    Organic Changes. In the event of any Organic Change, the Warrants shall, immediately after such Organic
Change, remain outstanding and shall thereafter, in lieu of or in addition to (as the case may be) the number of Ordinary Shares then issuable upon exercise of the Warrants, be exercisable for the kind and number of securities resulting from such
Organic Change to which the Warrantholders would have received upon the consummation of such Organic Change if the Warrantholders had exercised the Warrants in full immediately prior to the consummation of such Organic Change and acquired the
applicable number of Ordinary Shares then issuable upon exercise of the Warrants as a result of such exercise (without taking into account any limitations or restrictions on the exercisability of the Warrants). The Company shall not effect any
Organic Change unless, prior to the consummation thereof, the surviving Person (if other than the Company or where the Company continues into another jurisdiction) resulting from such Organic Change shall assume, by written instrument substantially
similar in form and substance to this Agreement in all material respects (including with respect to the provisions of this Section 5.2), the obligation to deliver to the Warrantholders such cash, stock, securities or other
assets or property which, in accordance with the foregoing provision, the Warrantholders shall be entitled to receive upon exercise of the Warrants. The provisions of this Section 5.2 shall similarly apply to successive
Organic Changes.

	6.	 Loss or Mutilation. 



If (i) any mutilated Warrant Certificate is surrendered to the Warrant Agent or (ii) both (x) there shall be delivered to the Company
and the Warrant Agent (A) a claim by a Warrantholder as to the destruction, loss or wrongful taking of any Warrant Certificate of such Warrantholder, evidence reasonably satisfactory to the Company of such destruction, loss or taking, and a
request for a new replacement Warrant Certificate, and (B) such open penalty surety bond or other indemnity bond as may be required by the Company and the Warrant Agent to save each of them and any agent of either of them harmless from any loss
that either of them may suffer if a Warrant Certificate is replaced and (y) such other reasonable requirements as may be imposed by the Company have been satisfied, then, the Company shall execute and upon its written request the Warrant Agent
shall countersign and deliver to the registered Warrantholder of the lost, wrongfully taken, destroyed or mutilated Warrant Certificate, in exchange therefor or in lieu thereof, a new Warrant Certificate of the same tenor and for a like aggregate
number of Warrants. At the written request of such registered Warrantholder, the new Warrant Certificate so issued shall be retained by the Warrant Agent as having been surrendered for exercise, in lieu of delivery thereof to such Warrantholder, and
shall be deemed for purposes of Section 3.2 to have been surrendered for exercise on the date the conditions specified in clauses (i) or (ii) of the preceding sentence were first satisfied. 

Upon the issuance of any new Warrant Certificate under this Section 6, each of the Company and the Warrant Agent may
require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and other expenses (including the fees and expenses of the Warrant Agent and of counsel to the Company) in connection
therewith. 
 Each new Warrant Certificate executed and delivered pursuant to this Section 6 in lieu of any lost,
wrongfully taken or destroyed Warrant Certificate shall constitute an additional contractual obligation of the Company, whether or not the allegedly destroyed, lost or wrongfully taken Warrant Certificate shall be at any time enforceable by any
other Person, and shall be entitled to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered hereunder. 

The provisions of this Section 6 are exclusive and shall preclude (to the extent lawful) all other rights or
remedies with respect to the replacement of mutilated, lost, wrongfully taken, or destroyed Warrant Certificates. 
  

	7.    Reservation	 and Authorization of Ordinary Shares. 



(a)    The Company covenants that, for the duration of the Exercise Period, the Board will at all times have authority
pursuant to the Articles of Association and any applicable legal and regulatory requirements to issue such number of Ordinary Shares as from time to time shall be issuable upon the exercise in full of all outstanding Warrants (in each case, free of pre-emptive rights). The Company further covenants that the Board shall, from time to time, take all steps necessary to increase its authority to issue Ordinary Shares issuable upon the exercise in full of all
outstanding Warrants if at any time the Board’s authority to issue a number of Ordinary Shares would otherwise be insufficient to allow delivery of all the Ordinary Shares then deliverable 

  
 24 












 
upon the exercise in full of all outstanding Warrants. The Company covenants that all Ordinary Shares issuable upon exercise of the Warrants will, upon issuance, be duly and validly issued and
fully paid. The Company shall take all such actions as may be necessary to ensure that all such Ordinary Shares may be so issued without violation of any applicable law or governmental regulation or any requirements of any Exchange (except for
official notice of issuance which shall be immediately delivered by the Company upon each such issuance to the extent required to list the Ordinary Shares so issued). The Company covenants that all such Ordinary Shares issued pursuant to the
Warrants shall be compliant with the Articles of Association. 
 (b)    If and to the extent that Ordinary Shares shall
be issuable in certificated form upon exercise of Definitive Warrants in accordance with the terms of this Agreement, the Company shall so notify the Warrant Agent. The Warrant Agent shall thereafter be authorized to request from time to time from
the Company’s transfer agent share certificates required to honor the exercise of outstanding Definitive Warrants, and the Company shall authorize and direct such transfer agent to comply with all such requests of the Warrant Agent. The Company
shall supply its transfer agent with duly executed share certificates for such purposes. 
 8.    Transfers; Warrant
Transfer Books. 
 8.1.    Corporate Agency Office. The Warrant Agent will maintain an office (the
“Corporate Agency Office”) in the United States of America, where Warrant Certificates may be surrendered for registration of Transfer or exchange in accordance with this Section 8 and where Warrant
Certificates may be surrendered for exercise of Warrants evidenced thereby, which office is, as of the date of this Agreement. 150 Royall Street. Canton. MA 0202. Attention: Client Services. The Warrant Agent will give prompt written notice to all
Warrantholders of any change in the location of such office. 
 8.2.    Warrant Register. 

(a)    Registration Generally. The Company shall cause to be kept at the office of the Warrant Agent
designated for such purpose a warrant register (the “Warrant Register”) in which, subject to such reasonable regulations as the Warrant Agent may prescribe and such regulations as may be prescribed by law, the Company shall
provide for the registration of Warrants or Warrant Certificates and of Transfers or exchanges of Warrants or Warrant Certificates as herein provided. The Company and the Warrant Agent may deem and treat any Person in whose name a Warrants or a
Warrant Certificate is registered in the Warrant Register as the absolute owner of such Warrants or Warrant Certificate for all purposes whatsoever and neither the Company nor the Warrant Agent shall be affected by notice to the contrary. 

(b)    Registration of Global Warrants. The holder of any Global Warrant will be the Depositary or a nominee
of the Depositary in whose name such Global Warrant is registered. The Warrant holdings of Agent Members will be recorded on the books of the Depositary. The beneficial interests in any Global Warrant held by customers of Agent Members will be
reflected on the books and records of such Agent Members, and none of the Warrant Agent, the Company or the Depositary shall be responsible for recording such beneficial interests or their exchange, exercise, cancellation or transfer. 

  
 25 












 8.3.    Transfers. 

(a)    Definitive Warrants 

(i)    The Warrant Agent will give prompt written notice to the Company of any Transfer requested by the
holder of a Definitive Warrant. 
 (ii)    If the Definitive Warrants are represented by Warrant
Certificates, any Transfer of such Warrants shall be subject to the requirement to deliver a properly completed and duly signed assignment to the Warrant Agent (who shall in turn provide a copy of same to the Company), such assignment to be in the
form of assignment attached to the form of Warrant Certificate attached hereto as Exhibit A accompanied by a signature guarantee from an eligible guarantor institution participating in an approved signature guarantee program pursuant to Rule 17Ad-15 of the Exchange Act. If the Definitive Warrants are issued in electronic entry registered form, any Transfer of such Definitive Warrants shall be subject to the requirement to deliver such assignment
documentation as shall be required by the Warrant Agent. 
 (iii)    Any attempt to Transfer any
Definitive Warrants not in compliance with this Agreement shall be null and void ab initio, and the Company and the Warrant Agent shall not give any effect in their respective records to such attempted Transfer. 

(b)    Global Warrants. 

(i)    In the case of a Global Warrant, then so long as the Global Warrant is registered in the name of the
Depositary, (x) the holders of beneficial interests in the Warrants evidenced thereby shall have no rights under the Warrant Certificate with respect to such Global Warrant held on their behalf by the Depositary or the Custodian, and
(y) the Depositary may be treated by the Company, the Warrant Agent and any agent of the Company or the Warrant Agent as the absolute owner of such Global Warrant for all purposes whatsoever, except, in each case, to the extent set forth
herein. Accordingly, any such owner’s beneficial interest in the Global Warrant will be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or the Agent Members, and neither the
Company nor the Warrant Agent shall have any responsibility with respect to such records maintained by the Depositary or the Agent Members. Notwithstanding the foregoing, nothing herein shall (I) 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 the Depositary or (II) impair, as between the Depositary and the Agent Members, the operation of applicable
practices governing the exercise of the rights of a holder of a beneficial interest in any Warrant. Except as otherwise may be provided in this Agreement, the rights of beneficial owners in a Global Warrant shall be exercised through the Depositary
subject to the applicable procedures of the Depositary. 
 (ii)    Any holder of any Global Warrant
shall, by acceptance of such Global Warrant, agree that (x) ownership of a beneficial interest in the Warrants represented thereby shall be required to be reflected in book-entry form, and (y) the transfer


  
 26 












 
and exchange of Global Warrants or beneficial interests therein shall be effected through the book-entry system maintained by the Depositary, in accordance with this Agreement and the Warrant
Certificates and the applicable procedures of the Depositary therefor. 
 (iii)    Notwithstanding any
other provisions of this Agreement (other than the provisions set forth in Section 2.4(c)(ii)), a Global Warrant may only be transferred as a whole, and not in part, and only by (A) the Depositary, to a nominee of the
Depositary, (B) a nominee of the Depositary, to the Depositary or another nominee of the Depositary, or (C) the Depositary or any such nominee to a successor Depositary or its nominee. 

(iv)    In the event that a Global Warrant is exchanged for Definitive Warrants pursuant to
Section 2.4(c)(ii), such Warrants may be exchanged only in accordance with the provisions of Section 8.3(a) and Section 2.4(c) and such other procedures as may from time
to time be adopted by the Company that are not inconsistent with the terms of this Agreement or of any Warrant Certificate. 

(v)    At such time as all beneficial interests in a Global Warrant have been exchanged for Definitive
Warrants, repurchased, exercised or canceled, such Global Warrant shall be returned by the Depositary for cancellation or retained and canceled by the Warrant Agent. At any time prior to such cancellation, if any beneficial interest in a Global
Warrant is exchanged (including for Definitive Warrants), repurchased, exercised or canceled, the number of Warrants represented by such Global Warrant shall be reduced and the Warrant Agent shall make an adjustment on its books and records to
reflect such reduction; provided that, in the case of an adjustment on account of an exercise of Warrants, the Warrant Agent shall have no duty or obligation to make such adjustment until it has received notice from the Warrantholder of the
amount thereof. 
 8.4.    Exchange of Definitive Warrants. If the Definitive Warrants are at the time
represented by Warrant Certificates, at the option of the Warrantholder, Warrant Certificates may be exchanged at the Corporate Agency Office upon payment of the charges hereinafter provided for other Warrant Certificates evidencing a like aggregate
number of Definitive Warrants. Whenever any Warrant Certificates are so surrendered for exchange, the Company shall execute, and the Warrant Agent shall countersign and deliver, the Warrant Certificates of the same tenor and evidencing the same
aggregate number of Definitive Warrants as evidenced by the Warrant Certificates surrendered by the Warrantholder making the exchange; provided that the Warrant Agent shall have received (i) a written instruction of exchange in form
satisfactory to the Warrant Agent, duly executed by the Warrantholder thereof or by his, her or its attorney, duly authorized in writing, and (ii) surrender of the Warrant Certificate(s) representing the Definitive Warrants, duly endorsed for
transfer. 
 8.5.    Valid Obligations. All Warrant Certificates issued upon any registration of Transfer or
exchange of Warrant Certificates pursuant to this Agreement shall be the valid obligations of the Company, evidencing the same obligations, and entitled to the same benefits under this Agreement, as the Warrant Certificates surrendered for such
registration of Transfer or exchange. 
 8.6.    No Service Charge. No service charge shall be made for any
registration of Transfer or exchange of Warrant Certificates; provided, however, the Company may require payment of a 

  
 27 












 
sum sufficient to cover any documentary, stamp or other tax or other charge that may be imposed in connection with any registration of Transfer or exchange of Warrant Certificates. The Warrant
Agent shall promptly forward any such sum collected by it to the Company or to such Persons as the Company shall specify by written notice. For the avoidance of doubt, the Warrantholder shall be responsible for any documentary, stamp or other tax or
other charge that may be imposed in connection with any Transfer, any registration of Transfer or exchange of Warrant Certificates. 

8.7.    Reports of Ownership. The Warrant Agent shall, upon request of the Company from time to time, deliver to
the Company such reports of registered ownership of the Warrants and such records of transactions with respect to the Warrants and the Ordinary Shares issuable upon exercise of the Warrants as the Company may request. The Warrant Agent shall also
make available to the Company for inspection by the Company’s agents or employees, from time to time as the Company may request, such original books of accounts and records maintained by the Warrant Agent in connection with the issuance and
exercise of Warrants hereunder, such inspections to occur at the Corporate Agency Office during normal business hours. 

8.8.    Copies; Notice. The Warrant Agent shall keep copies of this Agreement and any notices given to
Warrantholders hereunder available for inspection by the Warrantholders during normal business hours at the Corporate Agency Office. The Company shall supply the Warrant Agent from time to time with such numbers of copies of this Agreement as the
Warrant Agent may reasonably request. 
  

	9.	 Other Rights of Warrantholders. 



9.1.    No Voting or Dividend Rights. No Warrantholder shall have or exercise, and each Warrantholder acknowledges
and agrees that it shall not have or exercise, any rights held by holders of Ordinary Shares solely by virtue hereof as a holder of Warrants, including the right to vote and to receive dividends and other distributions as a holder of Ordinary
Shares. Except as may be specifically provided for herein with respect to the Ordinary Shares issuable upon exercise of the Warrants: 

(a)    the consent of any Warrantholder, solely by reason of the ownership or possession of a Warrant or the Warrant
Certificate representing the same, shall not be required with respect to any action or proceeding of the Company; 

(b)    no such Warrantholder, solely by reason of the ownership or possession of a Warrant or the Warrant Certificate
representing the same, shall have any right to receive any cash dividends, stock dividends, allotments or rights or other distributions paid, allotted or distributed or distributable to the holders of outstanding Ordinary Shares prior to, or for
which the relevant record date preceded, the Exercise Date of such Warrant; and 
 (c)    no such Warrantholder shall
have any right not expressly conferred hereunder or by applicable law with respect to the Warrant(s) held by such Warrantholder. 

9.2.    Rights of Action. All rights of action against the Company in respect of this Agreement, except rights of
action vested in the Warrant Agent, are vested in the Warrantholders, and any Warrantholder, without the consent of the Warrant Agent or any other Warrantholder, may, in such Warrantholder’s own behalf and for such Warrantholder’s own
benefit, enforce, institute and maintain any suit, action or proceeding against the Company suitable to enforce, or otherwise in respect of, such Warrantholder’s rights provided in this Agreement. 

  
 28 












 9.3.    Treatment of Holders of Warrant Certificates. Every
Warrantholder, by accepting any Warrant, consents and agrees with the Company, with the Warrant Agent and with every subsequent holder of such Warrant that, prior to due presentment of such Warrant for registration of Transfer in accordance with
Section 8, the Company and the Warrant Agent may treat the Person in whose name the Warrant is registered as the owner thereof in the Warrant Register for all purposes and as the Person entitled to exercise the rights
granted under the Warrants, and neither the Company, the Warrant Agent nor any agent thereof shall be affected by any notice to the contrary. 
  

	10.	 Concerning the Warrant Agent. 



10.1.    Nature of Duties and Responsibilities Assumed. The Company hereby appoints the Warrant Agent to act as
agent of the Company as expressly set forth in this Agreement (without any implied terms or conditions). The Warrant Agent hereby accepts the appointment as agent of the Company and agrees to perform that agency upon the express terms and conditions
set forth in this Agreement and in the Warrants or as the Company and the Warrant Agent may hereafter agree in writing, by all of which the Company and the Warrantholders, by their acceptance thereof, shall be bound; provided, however, that
the terms and conditions contained in the Warrants are subject to and governed by this Agreement or any other terms and conditions hereafter agreed to by the Company and the Warrant Agent in writing. 

The Warrant Agent shall not, by countersigning any Warrant Certificate or by any other act hereunder, be deemed to make any representations as
to validity or authorization of (i) the Warrants or the Warrant Certificates (except as to its countersignature thereon), (ii) any securities or other property delivered upon exercise of any Warrant, (iii) the accuracy of the computation
of the number or kind or amount of stock or other securities or other property deliverable upon exercise of any Warrant, (iv) the independence of any Independent Financial Expert or (v) the correctness of any of the representations of the
Company made in such certificates that the Warrant Agent receives. The Warrant Agent shall not at any time have any duty to calculate or determine whether any facts exist that may require any adjustments pursuant to
Section 4 hereof with respect to the kind and amount of shares or other securities or any property issuable to Warrantholders upon the exercise of Warrants required from time to time. The Warrant Agent shall have no duty,
liability or responsibility to determine the accuracy or correctness of such calculation or with respect to the methods employed in making the same. The Warrant Agent shall not be accountable with respect to the validity or value (or the kind or
amount) of any Ordinary Shares or of any securities or property which may at any time be issued or delivered upon the exercise of any Warrant or upon any adjustment pursuant to Section 4 hereof, and it makes no
representation with respect thereto. The Warrant Agent shall not be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any Ordinary Shares or share certificates or other securities or property upon
the surrender of any Warrant Certificate for the purpose of exercise or upon any adjustment pursuant to Section 4 hereof or to comply with any of the covenants of the Company contained in Section 4
hereof. 

  
 29 












 The Warrant Agent shall not (x) be liable for any recital or statement of fact
contained herein or in the Warrant Certificates or for any action taken, suffered or omitted by it in the absence of bad faith on the belief that any Warrant Certificate or any other documents or any signatures are genuine or properly authorized,
(y) be responsible for any failure on the part of the Company to comply with any of its covenants and obligations contained in this Agreement or in the Warrant Certificates or (z) be liable for any act or omission under this Agreement
except for its own gross negligence, bad faith, fraud or willful misconduct (each as determined by a court of competent jurisdiction in a final and non-appealable judgment). 

The Warrant Agent is hereby authorized to accept and is protected in accepting instructions with respect to the performance of its duties
hereunder by Company Order and to apply to any director or officer named in such Company Order for instructions (which instructions will be promptly given in writing when requested), and the Warrant Agent shall not be liable for any action taken or
suffered to be taken by it in accordance with the instructions in any Company Order. 
 The Warrant Agent may execute and exercise any of
the rights and powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Warrant Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such
attorney or agent or for any loss to the Company resulting from any such act, default, neglect or misconduct, absent gross negligence, bad faith, fraud or willful misconduct (each as determined by a final
non-appealable judgment of a court of competent jurisdiction) in the selection and continued employment thereof. 

The Warrant Agent shall not be under any obligation or duty to institute, appear in or defend any action, suit or legal proceeding in respect
hereof, unless first indemnified to its satisfaction, but this provision shall not affect the power of the Warrant Agent to take such action as the Warrant Agent may consider proper, whether with or without such indemnity. The Warrant Agent shall
promptly notify the Company in writing of any claim made or action, suit or proceeding instituted against it arising out of or in connection with this Agreement. The Warrant Agent shall not be obligated to expend or risk its own funds or to take any
action that it believes would expose or subject it to expense or liability or to a risk of incurring expense or liability, unless it has been furnished with assurances of repayment or indemnity satisfactory to it (it being understood that the
indemnification set forth in Section 10.3 is satisfactory to the Warrant Agent for the purposes set forth therein). 

The Company shall perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further
acts, instruments and assurances as may reasonably be required by the Warrant Agent in order to enable it to carry out or perform its duties under this Agreement. 

The Warrant Agent shall act solely as agent of the Company hereunder and does not assume any obligation or relationship of agency or trust for
or with any of the Warrantholders or any beneficial owners of Warrants. Notwithstanding anything contained herein to the contrary, the Warrant Agent’s aggregate liability with respect to, arising from or in connection with this Agreement, or
from services provided or omitted to be provided under this Agreement, whether in contract, in tort or otherwise (except for any liability resulting from the Warrant Agent’s gross negligence, bad faith, fraud or willful misconduct (each as
determined by a court of competent 

  
 30 












 
jurisdiction in a final and non-appealable judgment)), is limited to, and shall not exceed, the amounts paid hereunder by the Company to the Warrant Agent
as fees and charges, but not including reimbursable expenses, during the twelve (12) months immediately preceding the event for which recovery from the Warrant Agent is being sought. 

The Warrant Agent shall have no responsibility or obligation to any owner of a beneficial interest in a Global Warrant, any Agent Member or
other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with respect to any beneficial ownership interest in the Warrants represented by such Global Warrant or with respect
to the delivery to any Agent Member, beneficial owner or other Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such Warrants. All notices and communications to be given to the Warrantholders
and all payments to be made to Warrantholders under the Warrants shall be given or made only to or upon the order of the Warrantholders (which shall be the Depositary or its nominee in the case of a Global Warrant). Except as set forth herein, the
rights of owners of beneficial interests in any Global Warrant shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Warrant Agent may rely and shall be fully protected in relying upon
information furnished by the Depositary with respect to its members, participants and any beneficial owners. 

10.2.    Right to Consult Counsel. The Warrant Agent may at any time consult with legal counsel satisfactory to it
(who may be legal counsel for the Company), and the Warrant Agent shall incur no liability or responsibility to the Company or to any Warrantholder for any action taken, suffered or omitted by it in the absence of bad faith in accordance with the
opinion or advice of such counsel. 
 10.3.    Compensation, Reimbursement and Indemnification. The Company
agrees to pay the Warrant Agent from time to time reasonable compensation relating to its services hereunder as set forth in a mutually agreed upon fee schedule and to reimburse the Warrant Agent for reasonable and documented out-of-pocket expenses and disbursements, including reasonable and documented counsel fees incurred in the preparation, delivery, negotiation, amendment, administration and
execution of this Agreement and the exercise and performance of its duties hereunder. The Company further agrees to indemnify the Warrant Agent and its employees, officers and directors, and to hold such Persons harmless against, any and all loss,
liability, damage, judgment, fine, penalty, claim, demand, settlement and reasonable and documented out-of-pocket cost or expense (including, without limitation, the
reasonable and documented fees and expenses of legal counsel) that may be paid, incurred or suffered by any such Person, or to which any such Person may become subject, without gross negligence, bad faith, fraud or willful misconduct on the part of
the Warrant Agent (which gross negligence, bad faith, fraud or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction), for any action taken, suffered,
or omitted to be taken by the Warrant Agent in connection with the execution, acceptance, administration, exercise and performance of its duties under this Agreement, including the reasonable and documented out-of-pocket costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly, or enforcing its rights hereunder. The provisions under this
Section 10 concerning the rights and immunities of the Warrant Agent shall survive the expiration of any Warrant and the termination of this Agreement and the resignation, replacement or removal of the Warrant Agent. 

  
 31 












 10.4.    Warrant Agent May Hold Company Securities. The Warrant
Agent and any stockholder, director, officer or employee of the Warrant Agent may buy, sell or deal in any of the warrants or other securities of the Company or its Affiliates, become pecuniarily interested in transactions in which the Company or
its Affiliates may be interested, contract with or lend money to the Company or its Affiliates or otherwise act as fully and freely as though it were not the Warrant Agent under this Agreement. Nothing herein shall preclude the Warrant Agent from
acting in any other capacity for the Company or for any other legal entity. 
 10.5.    Resignation and Removal;
Appointment of Successor. 
 (a)    The Warrant Agent may resign its duties and be discharged from all further
duties and liability hereunder (except liability arising as a result of the Warrant Agent’s own gross negligence, bad faith, fraud or willful misconduct, each as determined by a final, non-appealable
judgment of a court of competent jurisdiction) after giving sixty (60) days’ prior written notice to the Company. In the event the transfer agency relationship in effect between the Company and the Warrant Agent terminates, the Warrant
Agent will be deemed to have resigned automatically and be discharged from its duties under this Agreement as of the effective date of such termination, and the Company shall be responsible for sending any required notice to Warrantholders and
owners of any beneficial interest in the Warrants. The Company may remove the Warrant Agent upon ninety (90) days’ written notice, and the Warrant Agent shall thereupon in like manner be discharged from all further duties and liabilities
hereunder (except liability arising as a result of the Warrant Agent’s own gross negligence, bad faith, fraud or willful misconduct, each as determined by a final, non-appealable judgment of a court of
competent jurisdiction). The Warrant Agent shall, at the expense of the Company, cause notice to be given in accordance with Section 11.1(b) to each Warrantholder and owner of a beneficial interest in a Global Warrant of
said notice of resignation or notice of removal, as the case may be. Upon such resignation or removal, the Company shall appoint in writing a new Warrant Agent. If the Company shall fail to make such appointment within a period of thirty
(30) days after it has been notified in writing of such resignation by the resigning Warrant Agent or after such removal, then the Warrant Agent may apply to any court of competent jurisdiction for the appointment of a new Warrant Agent. Any
new Warrant Agent, whether appointed by the Company or by such a court, shall be (i) a bank or trust company, (ii) organized under the laws of the United States of America or one of the states thereof, (iii) authorized under the laws
of the jurisdiction of its organization to exercise corporate trust powers, (iv) having a combined capital and surplus of at least $50,000,000 and (v) having an office in the Borough of Manhattan, the City of New York. The combined capital
and surplus of any such new Warrant Agent shall be deemed to be the combined capital and surplus as set forth in the most recent annual report of its condition published by such Warrant Agent prior to its appointment; provided, however, such
reports are published at least annually pursuant to law or to the requirements of a United States federal, state or other supervising or examining authority. After acceptance in writing of such appointment by the new Warrant Agent, it shall be
vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as the Warrant Agent, without any further assurance, conveyance, act or deed; but if for any reason it shall be reasonably necessary or
expedient to execute and deliver any further assurance, conveyance, act or deed, the same shall be done at the reasonable expense of the Company, without additional liability to the predecessor resigning or removed Warrant Agent, and shall be
legally and validly executed and delivered by the resigning or removed Warrant Agent. Not later than the effective date of any such appointment, the Company shall file notice thereof with the resigning


  
 32 












 
or removed Warrant Agent. Failure to give any notice provided for in this Section 10.5(a), however, or any defect therein, shall not affect the legality or validity of
the resignation of the Warrant Agent or the appointment of a new Warrant Agent as the case may be. 
 (b)    Any
corporation or other legal entity into which the Warrant Agent or any new Warrant Agent may be merged, or any corporation or other legal entity resulting from any consolidation to which the Warrant Agent or any new Warrant Agent shall be a party,
shall be a successor Warrant Agent under this Agreement without any further act, provided that it is open for business on each Business Day and (i) is organized under the laws of the United States of America or one of the states thereof,
(ii) is authorized under the laws of the jurisdiction of its organization to exercise corporate trust or stock transfer powers and (iii) has a combined capital and surplus of at least $50,000,000. Any such successor Warrant Agent shall
promptly cause notice of its succession as Warrant Agent to be given in accordance with Section 11.1(b) to each Warrantholder and owner of a beneficial interest in a Global Warrant, in the case of the Warrantholders at such
Warrantholder’s last address as shown on the Warrant Register. 
 11.    Notices. 

11.1.    Notices Generally.

other address as shall have been set forth in a notice delivered in accordance with this Section 11.1(a).

 All notices and other communications hereunder shall be deemed duly given (i) upon
delivery, if served by personal delivery upon the Person for whom it is intended, (ii) on the third (3rd) Business Day after the date mailed if delivered by registered or certified mail, return receipt requested, postage prepaid, (iii) on
the following Business Day if delivered by a nationally-recognized, overnight, air courier or (iv) when delivered or, if sent after the close of business, on the following Business Day if sent by email, in each case, to the address set forth on
such Person’s signature page hereto or to such other address as may be designated in writing, in the same manner, by such Person. 

(b)    Where this Agreement provides for notice to Warrantholders of any event or delivery of any information or documents
to Warrantholders, such notice or delivery shall be sufficiently given (unless otherwise herein expressly provided) if in writing (including electronic mail communication) and sent via electronic, registered or certified mail, or delivered by hand
or nationally-recognized, overnight, air courier, to each Warrantholder affected by such event or entitled to receive such delivery, at the address of such Warrantholder as it appears in the Warrant Register, not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice or the making of such delivery. Where this Agreement provides for notice to the owners of a beneficial interest in a Global Warrant, such notice shall be distributed through
the Depositary in accordance with the procedures of the Depositary. Communications to owners shall be deemed to be effective at the time of dispatch to the Depositary. Neither the failure to provide any such notice or delivery described in this
Section 11.1(b), nor any defect in any notice or delivery so otherwise provided, to any particular Warrantholder or owner of a beneficial interest in a Global Warrant shall affect the sufficiency of such notice or delivery
with respect to other Warrantholders. Such notice or delivery may be waived in writing by the Person entitled to receive such notice or delivery, either before or after the event, and such waiver shall be the equivalent of such notice or delivery.

 11.2.    Required Notices to Warrantholders. In the event the Company shall propose to take any action of the
types described in Section 4.1(a), Section 4.1(b), Section 4.1(c), Section 4.1(d), Section 4.1(e) or
Section 5 (but only if any such action (i) would result in an adjustment to the Exercise Price or Warrant Share Number or a change in the type of securities or property to be delivered upon exercise of a Warrant, or
(ii) but for Section 4.1(f)(iv) would result in such an adjustment or change) then, and in each such case, the Company shall cause to be filed with the Warrant Agent and shall give to each Warrantholder and owner of a
beneficial interest in a Global Warrant, in accordance with Section 11.1(b), a notice of such proposed action. Such notice shall: (i) in the case of any action of the types described in
Section 4.1(a), Section 4.1(c), Section 4.1(e) or Section 5.2, specify the date on which such action is to become effective; (ii) in the
case of any dividend or distribution described in Section 4.1(b) or Section 4.1(d), specify the date on which a record is to be taken for the purposes of any such dividend or distribution; or
(iii) in the case of a Fundamental Transaction described in Section 5.1, specify the date on which such Fundamental Transaction is expected to become effective and the date as of which it is expected that holders of
outstanding Ordinary Shares of record shall be entitled to exchange their Ordinary Shares for Fundamental Transaction Consideration. Such notice shall be given, (a) in the case of any dividend or distribution covered by the foregoing clause
(ii) above, at least ten (10) Business Days prior to the Record Date for such dividend or distribution, and (b) in the case of any other action covered by the foregoing clauses (i) and (iii), at least fifteen (15) Business
Days prior to the applicable effective date thereof. Notwithstanding anything to the contrary herein, and without limitation of 

  
 34 












 
Section 4.1(h)(ii), the failure of the Company to file with the Warrant Agent and give to each Warrantholder and owner of a beneficial interest in a Global Warrant, in
accordance with Section 11.1(b), a notice as required pursuant to this Section 11.2 shall not in any way impair or affect the validity of any action of the Company described in
Section 4.1(a), Section 4.1(b), Section 4.1(c), Section 4.1(d), Section 4.1(e), Section 5.1
and Section 5.2; provided, that the failure of the Company to deliver such notice shall not limit the Company’s obligations thereunder. 

If at any time the Company shall cancel or abandon any of the proposed transactions for which notice has been given under this
Section 11.2 prior to the consummation thereof the Company shall give each Warrantholder and each owner of a beneficial interest in a Global Warrant notice of such cancellation or abandonment in accordance with
Section 11.1(b) hereof as promptly as practicable. 
  

	12.	 Inspection. 



The Warrant Agent shall cause a copy of this Agreement to be available at all reasonable times at the office of the Warrant Agent for
inspection by the Warrantholders and any owner of a beneficial interest in a Global Warrant. The Warrant Agent may require any Warrantholder to submit his, her or its Warrant Certificate(s), if any, for inspection by it. 

 

	13.	 Amendments. 



The Company and the Warrant Agent may, without the consent or concurrence of any of the Warrantholders, by supplemental agreement or otherwise,
amend this Agreement for the purpose of making any changes or corrections in this Agreement that (i) are required to cure any ambiguity or to correct or supplement any defective or inconsistent provision or clerical omission or mistake or
manifest error herein contained, (ii) add to the covenants and agreements of the Company in this Agreement further covenants and agreements of the Company thereafter to be observed, or surrender any rights or powers reserved to or conferred
upon the Company in this Agreement or (iii) subject to the second proviso of this Section 13, are ministerial, administrative or de minimis and would enable the Warrants to be listed on a national or regional
securities exchange; provided, however, that in either case such amendment shall not adversely affect the rights or interests of the Warrantholders (or any Agent Member (on behalf of itself or any owner of a beneficial interest in a Global
Warrant)) hereunder in any respect. This Agreement may otherwise be amended by the Company and the Warrant Agent with the approval of the Required Warrantholders; provided that, (x) no such amendment shall materially and adversely affect
any Warrantholder or owner of a beneficial interest in a Global Warrant in a different and disproportionate manner relative to the other Warrantholders and owners of a beneficial interest in a Global Warrant unless such amendment is agreed to in
writing by such adversely affected Warrantholder or owner of a beneficial interest in a Global Warrant and (y) any amendment to Section 3.3, Section 4, Section 5,
this Section 13 or Section 14 (including any amendment to the definitions used in and material to such Sections) shall require the prior written consent of the Required Amendment Warrantholders.

 Upon the delivery of a certificate from an Appropriate Officer which states that the proposed amendment is in compliance with the terms
of this Section 13, the Warrant Agent shall join with the Company in the execution and delivery of any such amendment unless such 

  
 35 












 
amendment affects the Warrant Agent’s own rights, duties or immunities hereunder, in which case the Warrant Agent may, but shall not be required to, join in such execution and delivery. No
amendment to this Agreement shall be effective unless duly executed by the Warrant Agent. Upon execution and delivery of any amendment pursuant to this Section 13, such amendment shall be considered a part of this Agreement
for all purposes and every Warrantholder of a Warrant theretofore or thereafter countersigned and delivered hereunder shall be bound thereby. 

Promptly after the execution by the Company and the Warrant Agent of any such amendment, the Company shall give notice to the Warrantholders
and owners of a beneficial interest in a Global Warrant, providing a copy of such amendment, in accordance with the provisions of Section 11.1(b). Any failure of the Company to deliver such notice or any defect therein
shall not, however, in any way impair or affect the validity of any such amendment. 
  

	14.	 Waivers. 



The Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if (i) the
Company has obtained the prior written consent of the Required Warrantholders for such waiver (it being understood that any waiver by the Company with respect to Section 3.3, Section 4 or
Section 5 shall require the prior written consent of the Required Amendment Warrantholders), and (ii) an amendment to this Agreement is necessary for such waiver, any consent required pursuant to
Section 13 has been obtained. 
  

	15.	 Equitable Relief. 



Each of the Company, the Warrant Agent and the Warrantholders acknowledges that a breach or threatened breach by such party of any of its
obligations under Sections 6, 8.3, 8.4, 8.7, 12, 13, 14,.20, 21 and 23 of this Agreement would give rise to irreparable harm to the
non-breaching party for which monetary damages would not be an adequate remedy and hereby agrees that in the event of a breach or a threatened breach by any of them of any such obligations, the non-breaching party shall, in addition to any and all other rights and remedies that may be available to it in respect of such breach, be entitled to equitable relief, including a restraining order, an injunction,
specific performance and any other relief that may be available from a court of competent jurisdiction. 
  

	16.	 Headings. 



The section headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation
of this Agreement. 
  

	17.	 Counterparts. 



This Agreement may be executed in two or more counterparts, each of which will be deemed to be an original, but all of which together
constitute one and the same instrument. Any signature page delivered electronically or by facsimile (including transmission by .pdf, other fixed imaged form or DocuSign or similar program) will be binding to the same extent as an original signature
page.

	18.	 Severability. 



The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision hereof will not affect the
validity or enforceability of the other provisions hereof provided that if any provision of this Agreement, as applied to any party or to any circumstance, is adjudged by a court or governmental body not to be enforceable in accordance with
its terms, the parties agree that the court or governmental body making such determination will have the power to modify the provision in a manner consistent with its objectives such that it is enforceable, and/or to delete specific words or
phrases, and in its reduced form, such provision will then be enforceable and will be enforced; provided, further, that if such excluded provision shall adversely affect the rights, immunities, liabilities, duties or obligations of the
Warrant Agent, the Warrant Agent shall be entitled to resign upon ten (10) days’ prior written notice to the Company. 
  

	19.	 Persons Benefiting. 



This Agreement shall be binding upon and inure to the benefit of the Company, the Warrantholders and the Warrant Agent, and their respective
successors and assigns. Nothing in this Agreement, express or implied, is intended to confer upon any person other than the Company, the Warrant Agent, the Warrantholders and, to the extent provided herein, the owners of a beneficial interest in a
Global Warrant, any rights or remedies under or by reason of this Agreement or any part hereof provided that the Non-Recourse Parties are express third-party beneficiaries of
Section 22. Each Warrantholder, by acceptance of a Warrant, agrees to all of the terms and provisions of this Agreement applicable thereto. 
  

	20.	 Applicable Law. 



THIS AGREEMENT, EACH WARRANT ISSUED HEREUNDER AND ANY CONTRACTUAL AND NON-CONTRACTUAL RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO AND THERETO, INCLUDING THE INTERPRETATION, CONSTRUCTION, VALIDITY AND ENFORCEABILITY THEREOF, SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF NEW YORK. Each of the Company, each
Warrantholder and the Warrant Agent agrees that it shall bring any litigation with respect to any claim arising out of or related to this Agreement or any Warrant, exclusively in the courts of the State of New York located in New York County and of
the U.S. federal courts located in the Southern District of New York (together with the appellate courts thereof, the “Chosen Courts”). In connection with any claim arising out of or related to this Agreement or any Warrant, each of
the Company, each Warrantholder and the Warrant Agent hereby irrevocably and unconditionally (i) submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any objection that such Person may now or hereafter have to the laying
of venue of any action or proceeding arising out of or relating to this Agreement or any Warrant in the Chosen Courts, (iii) waives any objection that the Chosen Courts are an inconvenient forum or as not having jurisdiction over either the
Company, the Warrantholder or the Warrant Agent, (iv) agrees that service of process in any such action or proceeding shall be effective if notice is given in accordance with this Agreement, although nothing contained in this Agreement shall
affect the right to serve process in any other manner permitted by law, and (v) agrees not to seek a transfer of venue on the basis that another forum is more convenient. 

  
 37 












 
Notwithstanding anything herein to the contrary, (x) nothing in this Section 20 shall prohibit any Person from seeking or obtaining orders for conservatory or
interim relief from any court of competent jurisdiction and (y) each of the Company, each Warrantholder and the Warrant Agent agrees that any judgment issued by a Chosen Court may be recognized, recorded, registered or enforced in any
jurisdiction in the world and waives any and all objections or defenses to the recognition, recording, registration or enforcement of such judgment in any such jurisdiction. 

  
 38 












 21.    Waiver of Certain Damages. To the extent permitted by
applicable law, each of the Company, each Warrantholder and the Warrant Agent agrees not to assert, and hereby waives, any claim against any other party, on any theory of liability, for special, indirect, consequential or punitive damages (as
opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any Warrant or any of the transactions contemplated hereby, even if that party has been advised of or has foreseen the possibility of such
damages. 
 22.    No Recourse. Notwithstanding anything express or implied in this Agreement, each
Warrantholder and the Warrant Agent covenants, agrees and acknowledges that no recourse under this Agreement or any documents or instruments delivered in connection with this Agreement shall be had against any of the former, current or future direct
or indirect equityholders, unitholders, directors, officers, employees, agents, Affiliates, members, financing sources, managers, general or limited partners or assignees, in each case, of the Company or any of its subsidiaries (collectively, but
not including the Company itself or any of its subsidiaries, the “Non-Recourse Parties”), whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of
any applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any of the Non-Recourse Parties, as such, for any
obligation or liability of the Company under this Agreement or any documents or instruments delivered in connection herewith for any claim based on, in respect of or by reason of such obligations or liabilities or their creation; provided,
however, that nothing in this Section 22 shall relieve or otherwise limit the liability of (i) any of the Non-Recourse Parties or the Company in the case of fraud or
(ii) the Company for any breach or violation of its obligations under this Agreement or such agreements, documents or instruments. 

23.    Confidentiality. The Warrant Agent and the Company agree that the fee schedule contemplated by
Section 10.3, the Warrant Register, the number of Warrants held by each Warrantholder and other personal, non-public information of each Warrantholder which may be exchanged or
received pursuant to the negotiation or carrying out of this Agreement shall remain strictly confidential and shall not be disclosed to any other Person, except as may be required by applicable law or regulation, including pursuant to subpoenas from
applicable government authorities, or pursuant to the requirements of the Securities and Exchange Commission. However, each party may disclose relevant aspects of any such confidential information to its officers, affiliates, agents, subcontractors
and employees to the extent reasonably necessary to perform its duties and obligations under this Agreement and such disclosure is not prohibited by applicable law; provided that the disclosing party shall inform such other Persons of the
confidential nature of such information and be responsible for any breach of this Section 23 by any such other Person. 

24.    Force Majeure. Notwithstanding anything to the contrary contained herein, the Warrant Agent will not be liable
for any delays or failures in performance resulting from acts beyond its reasonable control including, without limitation, acts of God, pandemics, epidemics, terrorist acts, shortage of supply, breakdowns or malfunctions, interruptions or
malfunction of computer facilities, or loss of data due to power failures or mechanical difficulties with information storage or retrieval systems, labor difficulties, war, or civil unrest.
