the Company agrees to issue the Notes, and each Purchaser agrees to subscribe a Note with the principal amount set forth opposite such Purchaser’s name on Exhibit A at the issue price of 100% of the principal amount of such Note (the

Section 2.2 Interest Applicable. Interest shall accrue on the Accreted Principal Amount of the Note (in each case computed on the
basis of a 365/366-day year and the actual number of days elapsed in any year) at an annual rate equal to 7.0% per annum or (if less) at the highest rate then permitted under applicable law, which shall be payable by adding such interest to the
Accreted Principal Amount of the Note on each Interest Payment Date (as defined below), and on the final maturity of the Note (the “PIK Amount”). At any time, the outstanding principal amount of the Note, including all PIK Amounts
added thereto through such time, is referred to herein as the “Accreted Principal Amount.” The Company shall pay to the holder of the Note all accrued interest (including interest on the Accreted Principal Amount) on each
anniversary date of the Note (each, an “Interest Payment Date”), including the final maturity date of the Note. Interest shall accrue on any principal payment due under the Note (including as to accrued interest added to the
principal) until such time as payment therefor is actually delivered to the holder of the Note.

 Section 2.3 Closing. Subject to Sections 6.1 and 6.2, the closing (the
“Closing”) of the issuance and subscription of the Notes (the “Purchase”) shall occur on a date (the “Closing Date”) no later than three business days after the date of this Agreement. At the
Closing, (i) the Purchasers shall deliver or cause to be delivered to the Company the Issue Price, and (ii) the Company shall issue to the Purchasers the Notes. At each Closing, the Company shall deliver to each Purchaser the Note to be
purchased by such Purchaser.

conversion and acceleration of the Note are set forth in the form of Note attached hereto as Exhibit B. 
 Section 2.5
Subordination. With the exception of up to $10 million of secured indebtedness owed to Natixis under the factoring agreement between the Company and Natixis, the Note and the interest accrued under the Note are the senior obligations of the
Company and will rank pari passu in right of payment with all other senior and unsubordinated obligations of the Company. 

Section 2.6 No Preferential Right to Subscription. Pursuant to article L.225-132 of the French commercial code, the decision to
issue the Note automatically waives the right for any existing shareholder of the Company to a preferential right (droit préférentiel de souscription) for the subscription of the Underlying Shares to be issued by the Company

transaction, whether as underwriter, advisor, investor or otherwise) of Sanctions. 
 Section 4.24 Disclosure Controls and
Procedures. The Company has established and maintains disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) that are effective in all material respects to ensure that material information relating to the
Company, including any consolidated Subsidiaries, is made known to its chief executive officer and chief financial officer by others within those entities. The Company’s certifying officers have evaluated the effectiveness of the Company’s
controls and procedures as of the end of the period covered by the most recently filed annual report under the Exchange Act (such date, the “Evaluation Date”). The Company presented in its most recently filed annual report under the
Exchange Act the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no material changes in the

(A) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and (B) no change in the Company’s internal control over financial reporting that has materially affected, or is
reasonably likely to materially affect, the Company’s internal control over financial reporting. 
 Section 4.26 Absence of
Material Changes. Subsequent to the respective dates as of which information is given in the Company Reports, and except as may be otherwise disclosed in such Company Reports, there has not been (i) any Material Adverse Effect,
(ii) any transaction which is material to the Company, (iii) any obligation, direct or contingent (including any off-balance sheet obligations), incurred by the Company, which is material to the Company, (iv) any


  
 13 








 
dividend or distribution of any kind declared, paid or made on the capital stock of the Company, (v) any change in the capital stock (other than a change in the number of outstanding
Ordinary Shares or ADSs due to grants of stock under the Company’s stock incentive plans existing on the date hereof or the issuance of shares upon the exercise of outstanding options or warrants) or (vi) any issuance of options, warrants,
convertible securities or other rights to purchase the capital stock (other than grants of stock options under the Company’s stock option plans existing on the date hereof) of the Company. 

Section 4.27 Brokers Fees. Neither the Company nor any of its Subsidiaries is a party to any contract, agreement or understanding
with any person (other than the Engagement Letter, dated April 27, 2016, between the Company and B. Riley) that would give rise to a valid claim against the Company for a brokerage commission, finder’s fee or like payment in connection
with the offering and issuance of any Note or any transaction contemplated by this Agreement. 
 Section 4.28 Listing and
Maintenance Requirements. The Company is subject to and in compliance in all material respects with the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, as applicable. The ADSs are registered pursuant to
Section 12(b) of the Exchange Act and are listed on the New York Stock Exchange, and the Company has taken no action designed to, or reasonably likely to have the effect of, terminating the registration of the ADSs under the Exchange Act or
delisting the ADSs from the New York Stock Exchange, nor has the Company received any notification that either the SEC or the New York Stock Exchange is contemplating terminating such registration or listing. The Conversion Shares will be duly
authorized for listing on the New York Stock Exchange immediately upon conversion of each Note in accordance with the terms of each Note and the issuance of the ADSs by the Depositary following the deposit of the Underlying Shares. 

Section 4.29 Sarbanes-Oxley Act. The Company is in compliance in all material respects with all applicable provisions of the
Sarbanes-Oxley Act of 2002 and all applicable rules and regulations promulgated thereunder or implementing provisions thereof that are then in effect. 

Section 4.30 New York Stock Exchange Approval Rules. No further approval of the stockholders of the Company under the rules and
regulations of the New York Stock Exchange is required for the Company to issue and deliver the Notes to Purchaser or the Conversion Shares upon conversion of each Note. 

Section 4.31 No General Solicitation. Neither the Company nor any person acting on its or their behalf has engaged in any general
solicitation or general advertising in connection with the offering or issuance of any Note, including but not limited to the methods described in Rule 502(c) under the Securities Act. 

Section 4.32 Integration. No offers and sales of securities of the same or similar class as the Notes have been made by the
Company or on its behalf during the six-month period ending with the date of this Agreement and no such offers or sales are currently being made or contemplated (in each case, whether pursuant to outstanding warrants, options, convertible or
exchangeable securities, acquisition agreements or otherwise). Neither the Company nor any other person acting on its behalf will, directly or indirectly, offer or sell any securities of the same or similar class as the Notes, or take any other
action, so as to cause the offer and issuance of the Notes to fail to be entitled to the exemption afforded by Regulation D under the Securities Act.

 ARTICLE V 

OTHER AGREEMENTS 

Section 5.1 Depositary. As more fully described in the Notes, upon conversion of all or any portion of a Note held by a Purchaser
in accordance with the terms thereof, the Company will cause the Depositary to deliver the relevant number of Conversion Shares to such Purchaser against deposit of the Underlying Shares, pursuant to the Deposit Agreement dated as of April 14,
2011 (the “Deposit Agreement”) among the Company, The Bank of New York Mellon, as depositary (the “Depositary”), and the owners and holders from time to time of the ADSs issued thereunder, and such Purchaser shall
cooperate with the Company and the Depositary in connection therewith. 
 Section 5.2 Beneficial Ownership Limitation. 

(a) No Purchaser shall request that a Note held by it be converted, and the Company shall not effect the conversion of a Note to the extent
that, after giving effect to such issuance after conversion, such Purchaser (together with such Purchaser’s Affiliates and any other person or entity acting as a group together with such Purchaser or any of such Purchaser’s Affiliates
(collectively, the “Concert Parties”)), would beneficially own ADSs or Ordinary Shares in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of ADSs or Ordinary
Shares beneficially owned by a Purchaser and its Concert Parties shall include the number of Ordinary Shares issuable upon conversion of the portion of the Note with respect to which such determination is being made, but shall exclude the number of
Ordinary Shares which would be issuable upon (i) conversion of the remaining portion of the Note beneficially owned by such Purchaser and (ii) conversion or exercise of the unexercised or unconverted portion of any loan to or securities of
the Company (or any successor thereto) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Purchaser or any of its Concert Parties. Except as set forth in the preceding sentence,
for purposes of this Section 5.2, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by each Purchaser that the Company
is not representing to such Purchaser that such calculation is in compliance with Section 13(d) of the Exchange Act and such Purchaser is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the
limitation contained in this Section 5.2 applies, the determination of whether and the extent to which a Note may be converted (in relation to other loans or securities owned by a Purchaser together with any Affiliates) shall be made in good
faith by the Purchaser holding such Note in consultation with its own counsel. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and
regulations promulgated thereunder. For purposes of this Section 5.2, in determining the number of outstanding Ordinary Shares (including Ordinary Shares represented by ADSs), each Purchaser may rely on the number of outstanding Ordinary Shares
(including Ordinary Shares represented by ADSs) as reflected in (x) the Company’s (or its successor’s) most recent periodic or annual report, as the case may be, 

  
 15 








 
filed with the SEC, (y) a more recent public announcement by the Company (or its successor) or (z) any other notice by the Company or the Depositary (or its successor or
successor’s depositary) setting forth the number of Ordinary Shares (including Ordinary Shares represented by ADSs) outstanding. Upon the written or oral request of any Purchaser, the Company shall within two business days confirm orally and in
writing to such Purchaser the number of Ordinary Shares (including Ordinary Shares represented by ADSs) then outstanding. In any case, the number of Ordinary Shares (including Ordinary Shares represented by ADSs) outstanding shall be determined
after giving effect to the conversion or exercise of loans or securities of the Company, including the Notes, by the applicable Purchaser or its Concert Parties since the date as of which such number of outstanding Ordinary Shares (including
Ordinary Shares represented by ADSs) was reported. The “Beneficial Ownership Limitation” shall be 9.99% of the number of Ordinary Shares (including Ordinary Shares represented by ADSs) outstanding immediately after giving effect to
the issuance of the Conversion Shares issuable upon conversion of the applicable Note. Purchaser, upon not less than 61 days’ prior notice to the Company, may increase or decrease (including, for the avoidance of doubt, to 0%) the percentage
constituting the Beneficial Ownership Limitation, and the provisions of this Section 5.2 shall continue to apply to such increased or decreased Beneficial Ownership Limitation. Any such increase or decrease will not be effective until the 61st
day after such notice is delivered to the Company. The provisions of this Section 5.2 shall be construed and implemented in a manner otherwise than in strict conformity with the terms hereof in order to correct such terms (or any portion
thereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this
Section 5.2 shall apply to any successor to Purchaser. 
 (b) Notwithstanding the foregoing, the limitations contained in this
Section 5.2 shall not (i) restrict or limit any conversion or prepayment of the Notes in connection with an Organic Change as contemplated by and defined in the Notes, or (ii) apply to any Purchaser other than Nokomis. 

Section 5.3 Supplemental Listing Application. Within two business days following the Closing Date, the Company shall file with the
New York Stock Exchange a supplemental listing application reflecting the transactions contemplated hereby. 
 Section 5.4 Listing
of Shares; Certificates. The Company covenants that all Conversion Shares will, at all times that any Note is convertible, be duly approved for listing subject to official notice of issuance on the New York Stock Exchange. The Company covenants
that the certificates, if any, representing the ADRs to be issued to evidence any Conversion Shares issued upon conversion of Notes will comply with applicable law.

V, until such time as such Accreted Principal Amount (including any accrued and unpaid interest) has been paid. For the avoidance of doubt, any reference in this Note to the conversion of the Note into ADSs shall mean the issuance of ADSs following
conversion of the Note in accordance with the procedure set forth in Section 5.1(d). 
 ARTICLE IV

respective affiliates in an aggregate amount in excess of $10,000,000 (or its foreign currency equivalent), unless such indebtedness is discharged, or such acceleration is rescinded, stayed or annulled, within any applicable cure period set forth in
the relevant agreement or instrument; or 
 (f) one or more final non-appealable judgments for the payment of money in any aggregate amount
in excess of $10,000,000 shall be rendered against the Company, any subsidiary of the Company or any of their respective affiliates and the same shall remain undischarged for a period of sixty (60) days during which execution shall not be

(a) If an Event of Default with respect to the Company described in subsection (c) of Section 4.1 has occurred, the Note shall
automatically become immediately due and payable. 
 (b) If any other Event of Default has occurred and is continuing, the holder of the Note
may at any time at his, her or its option, by notice to the Company, declare the Note to be immediately due and payable. 
 (c) Upon the Note
becoming due and payable under this Section 4.2, whether automatically or by declaration, the Note will forthwith mature and the entire unpaid Accreted Principal Amount (including any accrued and unpaid interest) shall all be immediately due
and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. 

Section 4.3 Other Remedies. If any Event of Default has occurred and is continuing, and irrespective of whether the Note has
become or has been declared immediately due and payable under Section 4.2, the holder of the Note may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the
specific performance of any agreement contained herein, for an injunction against a violation of any of the terms hereof or thereof or in aid of the exercise of any power granted hereby or thereby or by law or otherwise. 

Section 4.4 No Waivers or Election of Remedies; Expenses. No course of dealing and no delay on the part of the holder of the Note

Note without any deduction for any setoff or counterclaim. No right, power or remedy conferred by the Purchase Agreement or by the Note upon the holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or
now or hereafter available at law, in equity, by statute or otherwise. The Company will pay to the holder of the Note on demand such further amount as shall be sufficient to cover all reasonable costs and expenses of such holder incurred in any
enforcement or collection under this Article IV, including, without limitation, reasonable attorneys’ fees, expenses and disbursements. 

Section 4.5 Waiver of Demand. The Company hereby waives diligence, presentment, protest and demand and notice of protest and

 ARTICLE V 

CONVERSION 

Section 5.1 Conversion Procedure. 

(a) At any time prior to the payment of this Note in full, the holder of this Note may convert all or any portion of the outstanding Accreted
Principal Amount (including any accrued and unpaid interest) of this Note into a number of ADSs (excluding any fractional ADS) equal to the product obtained by dividing (i) the portion of the Accreted Principal Amount designated by such holder
to be converted, by (ii) the Conversion Rate then in effect. 
 (b) Except as otherwise expressly provided herein, each conversion of
this Note shall be deemed to have been effected as of the close of business on the date on which this Note has been surrendered for conversion at the principal office of the Company (the “Conversion Date”). At such time as such
conversion has been effected, the rights of the holder of this Note as such holder to the extent of the conversion shall cease, and the Person or Persons in whose name or names the ADSs are to be issued upon such conversion shall be deemed to have
become the holder or holders of record of the ADSs represented thereby. 
 (c) Notwithstanding anything herein to the contrary, including any
adjustments to the Conversion Rate pursuant to Sections 5.3 or 5.4, the Company may not issue, upon conversion of this Note and any other Notes under the Purchase Agreement, a number of ADSs that would exceed in the aggregate 20,000,000 (subject to
adjustment as provided in Section 5.3 below) Ordinary Shares and ADSs as of the date of issuance of such ADSs (such number of shares, the “Issuable Maximum”). If, pursuant to any adjustment to the Conversion Rate contemplated
in this Article V, the conversion of the Note would result in the issuance of ADSs that would exceed the Issuable Maximum, then the Conversion Rate shall be further adjusted such that that maximum number of ADSs issuable upon conversion of the Note
shall not exceed the Issuable Maximum. 
 (d) As soon as possible after a conversion has been effected (but in any event within five
(5) business days in the case of clause (i) below), the holder of this Note shall subscribe for the number of Ordinary Shares issuable upon conversion (in whole or in part) of this Note, and the Company shall do the following: 

(i) register the issuance to the converting holder of the number of Ordinary Shares issuable upon conversion (in whole or in part) of this
Note (the “Underlying Shares”) in the Company’s share transfer registry; 
 (ii) issue the Underlying Shares and
deposit such Underlying Shares with The Bank of New York Mellon, as depositary (the “Depositary”), in the name and on behalf of the holder of the Note; 

(iii) cause the Depositary to issue and deliver to the converting holder certificates or a book-entry transfer for the number of ADSs to which
Purchaser shall be entitled against deposit of the Underlying Shares, pursuant to the Deposit Agreement dated as of April 14, 2011 (the “Deposit Agreement”) among the Company, the Depositary and the owners and holders from time
to time of the ADSs issued thereunder; and 

  
 6 








 (iv) deliver to the converting holder a new Note representing any portion of the Accreted
Principal Amount (including any accrued and unpaid interest) that was represented by the Note surrendered to the Company in connection with such conversion, but which was not converted or which could not be converted because it would have required
the issuance of a fractional Ordinary Share. 
 The converting holder shall cooperate with the Company and the Depositary to facilitate the process outlined
above, including through the execution of a subscription form for the Ordinary Shares satisfactory to the converting holder and the execution of a power of attorney authorizing the Company to deliver the Underlying Shares to the Depositary on such
holder’s behalf. 
 (e) If a fractional ADS would, except for the provisions hereof, be deliverable upon conversion of this Note, the
Company, in lieu of delivering such fractional share, shall in the event the conversion is being consummated in connection with repayment in full of the Note, pay in cash an amount equal to the market price of such fractional share based on the
closing price of the ADSs on the New York Stock Exchange (the “Closing Sale Price”) on the Conversion Date. 
 (f) The
issuance of the Underlying Shares and ADSs upon conversion of this Note shall be made without charge to the holder hereof for any issuance tax in respect thereof or other cost incurred by the Company in connection with such conversion and the
related issuance of Underlying Shares and ADSs, unless the tax is due because the holder requests such Underlying Shares and ADSs to be issued in a name other than the holder’s name, in which case the holder shall pay the tax. Upon conversion
of this Note, the Company shall take all such actions as are necessary in order to ensure that the Ordinary Shares and ADSs issuable with respect to such conversion shall be validly issued, fully paid and nonassessable. 

(g) The Company shall not close its books against the transfer of Ordinary Shares or ADSs issued or issuable upon conversion of this Note in
any manner which interferes with the timely conversion of this Note. 
 (h) The conversion of this Note shall be subject to the Beneficial
Ownership Limitations set forth in Section 5.2 of the Purchase Agreement, which are incorporated herein by reference. 

Section 5.2 Conversion Rate. The initial Conversion Rate shall be a number of Ordinary Shares (subject to adjustment as provided
in this Article V, the “Conversion Rate”) equal to US$1,000 divided by the Conversion Price, per US$1,000 Accreted Principal Amount (including any accrued and unpaid interest) of the Note. To address dilution of the conversion
rights granted under the Notes, the Conversion Rate shall be subject to adjustment from time to time pursuant to Sections 5.3 and 5.4. The “Conversion Price” shall be equal to 1.2 times the 10-trading day volume weighted average
price of the ADSs on the New York Stock Exchange beginning on April 28, 2016 and ending on May 12, 2016; provided, however, in no event shall the Conversion Price be below US$2.00 or exceed US$3.00. 

  
 7 








 Section 5.3 Adjustments to Conversion Rate. If the number of Ordinary Shares
represented by each ADS is changed, after the date of this Note, for any reason other than one or more of the events described in this Section 5.3, the Company shall make an appropriate adjustment to the Conversion Rate such that the number of
Ordinary Shares represented by the ADSs upon which conversion of the Notes is based remains the same. In addition, the Conversion Rate shall be adjusted from time to time by the Company as follows: 

(a) In case the Company shall, at any time or from time to time while any of the Notes are outstanding, pay a dividend in Ordinary Shares
(directly or in the form of ADSs) or make a distribution in Ordinary Shares to all or substantially all holders of Ordinary Shares (other than a dividend or distribution in connection with a transaction to which Section 5.4 applies), then the
Conversion Rate shall be adjusted based on the following formula: 
  

					
	CR1 = CR0 ×	  	OS1	  	
	  	OS0	  	

         where 

 

					
			
	        CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the trading day immediately preceding the ex-dividend date for such dividend or distribution;
			
	        CR1	  	=	  	the Conversion Rate in effect on the ex-dividend date for such dividend or distribution;
			
	        OS0	  	=	  	the number of Ordinary Shares outstanding at 5:00 p.m., New York City time, on the trading day immediately preceding the ex-dividend date for such dividend or distribution; and
			
	        OS1	  	=	  	the number of Ordinary Shares that would be outstanding immediately after, and solely as a result of, such dividend or distribution.

 Any adjustment made pursuant to this Section 5.3(a) shall become effective immediately prior to 9:00
a.m., New York City time, on the ex-dividend date for such dividend or distribution. If any dividend or distribution that is the subject of this Section 5.3(a) is declared but not so paid or made, the Conversion Rate shall be immediately
readjusted, effective as of the date the Board of Directors of the Company (the “Board of Directors”) publicly announces its decision not to pay or make such dividend or distribution, to the Conversion Rate that would then be in
effect if such dividend or distribution had not been declared. For purposes of this Section 5.3(a), the number of Ordinary Shares outstanding at 5:00 p.m., New York City time, on the trading day immediately preceding the ex-dividend date for
such dividend or distribution shall not include Ordinary Shares held in treasury, if any. The Company will not pay any dividend or make any distribution on Ordinary Shares held in treasury, if any. 

(b) In case outstanding Ordinary Shares (directly or in the form of ADSs) shall be subdivided or split into a greater number of Ordinary Shares
or combined or reverse split into a smaller number of Ordinary Shares (in each case, other than in connection with a transaction to which Section 5.4 applies), the Conversion Rate shall be adjusted based on the following formula: 

 

					
	CR1 = CR0 ×	  	OS1	  	
	  	OS0	  	


  
 8 








             where 

 

					
	        CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the trading day immediately preceding the effective date of such subdivision or combination;
			
	        CR1	  	=	  	the Conversion Rate in effect on the effective date of such subdivision or combination;
			
	        OS0	  	=	  	the number of Ordinary Shares outstanding at 5:00 p.m., New York City time, on the trading day immediately preceding the effective date of such subdivision or combination; and
	        OS1	  	=	  	the number of Ordinary Shares that would be outstanding immediately after, and solely as a result of, such subdivision or combination.

 Any adjustment made pursuant to this Section 5.3(b) shall become effective immediately prior to 9:00
a.m., New York City time, on the effective date of such subdivision or combination. 
 (c) In case the Company shall issue
rights (other than rights issued pursuant to a shareholders’ rights plan or a dividend or distribution on Ordinary Shares in Ordinary Shares as set forth in (a) above) or warrants to all or substantially all holders of its Ordinary Shares
(whether direct or in the form of ADSs), other than an issuance in connection with a transaction to which Section 5.4 applies, entitling them to purchase, for a period expiring within forty-five (45) calendar days of the date of issuance,
Ordinary Shares (directly or in the form of ADSs) at a price per Ordinary Share less than the average of the Closing Sale Prices of the ADSs divided by the number of Ordinary Shares then represented by each ADS during the ten (10) consecutive
trading day period ending on the trading day immediately preceding the ex-dividend date for the distribution, the Conversion Rate shall be adjusted based on the following formula: 

 

					
	CR1 = CR0 ×	 	OS0+X
	  	
	 	OS0+Y	  	

         where 

 

					
	        CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the trading day immediately preceding the ex-dividend date for such issuance;
			
	        CR1	  	=	  	the Conversion Rate in effect on the ex-dividend date for such issuance;
			
	        OS0	  	=	  	the number of Ordinary Shares outstanding at 5:00 p.m., New York City time, on the trading day immediately preceding the ex-dividend date for such issuance;
			
	        X	  	=	  	the total number of Ordinary Shares issuable (directly or in the form of ADSs) pursuant to such rights or warrants; and
			
	        Y	  	=	  	the number of Ordinary Shares equal to the quotient of (x) aggregate price payable to exercise such rights or warrants, divided by (y) the average of the Closing Sale Prices of the ADSs during the ten (10) consecutive trading day
period ending on the trading day immediately preceding the ex-dividend date for such issuance.


  
 9 








 Any adjustment made pursuant to this Section 5.3(c) shall become effective immediately prior
to 9:00 a.m., New York City time, on the ex-dividend date for such issuance. If any rights or warrants described in this Section 5.3(c) are not so issued, the Conversion Rate shall be immediately readjusted, effective as of the date the Board
of Directors publicly announces its decision not to issue such rights or warrants, to the Conversion Rate that would then be in effect if such issuance had not been declared. To the extent that such rights or warrants are not exercised prior to
their expiration or Ordinary Shares are otherwise not delivered pursuant to such rights or warrants upon the exercise of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the
adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of Ordinary Shares actually delivered. In determining the aggregate price payable to exercise such rights and warrants, there shall
be taken into account any consideration received by the Company for such rights or warrants and the value of such consideration (if other than cash, to be determined in good faith by the Board of Directors). For purposes of this Section 5.3(c),
the number of Ordinary Shares outstanding at 5:00 p.m., New York City time, on the trading day immediately preceding the ex-dividend date for such issuance shall not include Ordinary Shares held in treasury, if any. The Company will not issue any
such rights or warrants in respect of Ordinary Shares held in treasury, if any. 
 (d) In case the Company shall, by dividend or otherwise,
distribute to all or substantially all holders of its outstanding Ordinary Shares (whether direct or in the form of ADSs) of any class of capital stock of the Company or evidences of its indebtedness or assets (including securities, but excluding
(i) any dividends or distributions referred to in Section 5.3(a), (ii) any rights or warrants referred to in Section 5.3(c), (iii) any dividends or distributions referred to in Section 5.3(e), (iv) any dividends or
distributions in connection with a transaction to which Section 5.4 applies, or (v) any Spin-Offs to which the provisions set forth below in this Section 5.3(d) applies) (any of the foregoing hereinafter in this Section 5.3(d)
called the “Distributed Assets”), then, in each such case, the Conversion Rate shall be adjusted based on the following formula: 
  

					
	CR1 = CR0 ×	 	SP0	  	
	 	SP0 – FMV	  	

                 where 

 

					
	        CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the trading day immediately preceding the ex-dividend date for such distribution;
			
	        CR1	  	=	  	the Conversion Rate in effect on the ex-dividend date for such distribution;
			
	        SP0	  	=	  	the average of the Closing Sale Prices of the ADSs multiplied by the number of Ordinary Shares then represented by each ADS during the ten (10) consecutive trading day period ending on the trading day immediately preceding the
ex-dividend date for such distribution; and
			
	        FMV	  	=	  	the fair market value on the ex-dividend date for such distribution of the Distributed Assets so distributed applicable to one (1) Ordinary Share, as determined in good faith by the Board of Directors.

  

  
 10 








 In the event where there has been a payment of a dividend or other distribution on the Ordinary
Shares (directly or in the form of ADSs) or shares of capital stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company (a “Spin-Off”) that are, or when issued,
will be, traded or listed on the New York Stock Exchange, the Nasdaq Global Market, the Nasdaq Global Select Market or any other U.S. national securities exchange or market, then the Conversion Rate shall instead be adjusted based on the following
formula: 
  

					
	CR1 = CR0 ×	  	FMV0 + MP0	  	
	  	MP0	  	

             where 

 

					
	        CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the trading day immediately preceding the ex-dividend date for such distribution;
			
	        CR1	  	=	  	the Conversion Rate in effect on the ex-dividend date for such distribution;
			
	        FMV0	  	=	  	the average of the Closing Sale Prices of the Distributed Assets applicable to one (1) Ordinary Share during the ten consecutive trading day period commencing on and including the effective date of the Spin-Off (the
“Spin-Off Valuation Period”); and
			
	        MP0	  	=	  	the average of the Closing Sale Prices of the ADSs multiplied by the number of Ordinary Shares then represented by each ADS during the Spin-Off Valuation Period.

 Any adjustment made pursuant to this Section 5.3(d) shall become effective immediately prior to 9:00
a.m., New York City time, on the ex-dividend date for such distribution. If any dividend or distribution of the type described in this Section 5.3(d) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted,
effective as of the date the Board of Directors publicly announces its decision not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

Rights or warrants distributed by the Company to all holders of Ordinary Shares (whether direct or in the form of ADSs) entitling the holders
thereof to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”):
(i) are deemed to be transferred with such Ordinary Shares; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Ordinary Shares, shall be deemed not to have been distributed for purposes of this
Section 5.3 (and no adjustment to the Conversion Rate under this Section 5.3 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an
appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 5.3(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Note, are subject to
events, upon the occurrence of which such rights or warrants become exercisable 

  
 11 








 
to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record
date with respect to new rights or warrants with such rights. In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with
respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 5.3 was made, (A) in the case of any such rights or warrants that shall all have been
redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash
distribution, equal to the per share redemption or repurchase price received by a holder or holders of Ordinary Shares with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of
Ordinary Shares as of the date of such redemption or repurchase and (B) in the case of such rights or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if
such rights and warrants had not been issued. 
 No adjustment of the Conversion Rate shall be made pursuant to this Section 5.3(d) in
respect of rights or warrants distributed or deemed distributed on any Trigger Event to the extent that such rights or warrants are actually distributed to Purchaser upon conversion by Purchaser of this Note. 

(e) In case the Company shall pay a dividend or otherwise distribute to all or substantially all holders of its Ordinary Shares (direct or in
the form of ADSs) a dividend or other distribution of exclusively cash excluding (i) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary and (ii) any
dividend or distribution in connection with a transaction to which Section 5.4 applies, then the Conversion Rate shall be adjusted based on the following formula: 
  

					
	CR1 = CR0 ×	 	 SP0
	 	
	 	SP0 – DIV	 	

 where 
  

							
		 	CR0	 	=	 	the Conversion Rate in effect at 5:00 p.m., New York City time, on the trading day immediately preceding the ex-dividend date for such dividend or distribution;
				
		 	CR1	 	=	 	the Conversion Rate in effect on the ex-dividend date for such dividend or distribution;
				
		 	SP0	 	=	 	the average of the Closing Sale Prices of the ADSs multiplied by the number of Ordinary Shares then represented by each ADS during the ten (10) consecutive trading day period ending on the trading day immediately preceding the
ex-dividend date for such distribution; and
				
		 	DIV	 	=	 	the amount in cash per Ordinary Share the Company distributes to holders of its Ordinary Shares.


  
 12 








 Any adjustment made pursuant to this Section 5.3(e) shall become effective immediately prior
to 9:00 a.m., New York City time, on the ex-dividend date for such dividend or distribution. If any dividend or distribution of the type described in this Section 5.3(e) is declared but not so paid or made, the Conversion Rate shall be
immediately readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared. 
 (f) In case of purchases of the Ordinary Shares (directly or in the form of ADSs) pursuant to a tender offer or exchange offer
made by the Company or any Subsidiary of the Company for all or any portion of the Ordinary Shares (directly or indirectly in the form of ADSs), to the extent that the fair market value, as determined in good faith by the Board of Directors, of cash
and any other consideration included in the payment per Ordinary Share (or equivalent payment per Ordinary Share represented by the ADSs) exceeds the Closing Sale Price of the ADSs divided by the number of ADSs then represented by each ADS on the
trading day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (as it may be amended) (the “Expiration Date”), the Conversion Rate shall be adjusted based on the
following formula: 
  

					
	CR1 = CR0 ×	 	 FMV + (SP1 x OS1)
	 	
	 	SP1 x OS0	 	

 where 
  

							
		 	CR0	 	=	 	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Expiration Date;
				
		 	CR1	 	=	 	the Conversion Rate in effect immediately after 5:00 p.m., New York City time, on the Expiration Date;
				
		 	FMV	 	=	 	the fair market value, on the Expiration Date, of the aggregate value of all cash and any other consideration paid or payable for Ordinary Shares (directly or indirectly in the form of ADSs) validly tendered or exchanged and not
withdrawn as of the Expiration Date, as determined in good faith by the Board of Directors;
				
		 	OS1	 	=	 	the number of Ordinary Shares outstanding immediately after the last time tenders or exchanges may be made pursuant to such tender offer or exchange offer (the “Expiration Time”), after giving effect to the purchase
of all Ordinary Shares or ADSs, as the case may be, accepted for purchase or exchange in such tender or exchange offer;
				
		 	OS0	 	=	 	the number of Ordinary Shares outstanding immediately before the Expiration Time; and


  
 13 









							
		 	SP1	 	=	 	the average of the Closing Sale Prices of the ADSs multiplied by the number of Ordinary Shares then represented by each ADS during the ten (10) consecutive trading day period commencing on the trading day immediately after the
Expiration Date.

 Any adjustment made pursuant to this Section 5.3(f) shall become effective immediately prior to 9:00
a.m., New York City time, on the trading day immediately following the Expiration Date. If the Company, or one of its Subsidiaries, is obligated to purchase Ordinary Shares (directly or indirectly in the form of ADSs) pursuant to any such tender or
exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting all such purchases or all such purchases are rescinded, the Conversion Rate shall be readjusted to be the Conversion Rate that would then be
in effect if such tender or exchange offer had not been made. Except as set forth in the preceding sentence, if the application of this Section 5.3(f) to any tender offer or exchange offer would result in a decrease in the Conversion Rate, no
adjustment shall be made for such tender offer or exchange offer under this Section 5.3(f). 
 (g) In cases where: 

(i) the fair market value, as determined in good faith by the Board of Directors, of Distributed Assets and cash, including with respect to a
Spin-Off, as to which Sections 5.3(d) and 5.3(e) apply, applicable to one (1) Ordinary Share, distributed to holders of the Ordinary Shares (whether direct or in the form of ADSs) equals or exceeds the average of the Closing Sale Prices of the
