relevant company within the Group of such cessation, he shall be required to repay to the Company an amount equal to the difference between (i) the payment received on selling the Depositary
Receipts (acquired as a result of such exercise) at the Exercise Date; and (ii) the Purchase Price, unless the Supervisory Board, in its absolute discretion, decides otherwise. The amount of such repayment shall not be reduced to take into
account any taxes paid by the Participant in respect of such exercised Option.

from the date the Participant’s status as Employee or member of the Supervisory Board ceases, unless the Supervisory Board, in its absolute discretion, decides otherwise. For the purposes of this Article 7.10, the Participant’s status as
Employee or member of the Supervisory Board shall continue where the Participant retires or retires early or is on military leave, sick leave or other bona fide leave of absence. 

 

	7.11	Transfers within the Group. If a Participant, while continuing to be employed within the Group, is transferred or transfers to work in another country and the
CEO is satisfied that the rights of the Participants under the Plan are adversely affected by such transfer, the CEO may permit the Participant to exercise his Options in the period commencing three (3) months before and ending three
(3) months after the date of transfer. Upon the expiry of such period, any Option to the extent unexercised can no longer be exercised under this Article 7.11 and shall be exercisable at such other time as provided in the Option Agreement of
the Participant. The decisions taken by the CEO in all cases falling within the provisions of this Article 7.11 shall be final and binding.

cancellation referred to in subsection (i) pay to the Participant for each Depositary Receipt or Share subject to such Option, an amount in cash equal to the excess of the value of the property (including cash) received by the holder of a
Depositary Receipt or Share as a result of such event over the Exercise Price; or 

  

	 	(ii)	 provide for the exchange of each Option outstanding immediately prior to such event (whether or not then exercisable) with an option with respect to
some or all of the property for which Depositary Receipts or Shares are exchanged in such transaction and, as a result, make any necessary equitable

adjustment in the exercise price of the new option and/or the number of Depositary Receipts or Shares amount of property subject to the option or, as appropriate, provide for a cash payment to

	6.2	The total number of Shares in regard to which Options may be granted pursuant to this Plan is 5,273,371 Shares. 

 

	7	Terms and Conditions of Options 

  

	7.1	Power to grant Options 

Subject to Article 5, Options may be granted to Employees, Advisors and Board Members by the CEO, with the prior approval of the
Compensation Committee. 
  

	7.2	Option Agreements 

 Each
Option shall be evidenced by an Option Agreement to be entered into between: 
  

	 	a.	the relevant Employee and the Company, setting forth the terms and conditions pertaining to the Options granted. Such Option Agreements shall take into account the tax
regime in the country in which the relevant Employee is employed by the Company or by a Group Company; or 

  

	 	b.	the relevant Advisor or member of the Board or the board of a Group Company and the Company, setting forth the terms and conditions pertaining to the Options granted.
Such Option Agreements shall take into account the tax regime in the country in which the relevant Advisor or Board Member reside, 

 and shall in both cases, together and concurrently with this Plan set out the rights and obligations pertaining to the Options subject to local legal and regulatory requirements. 

 

	7.3	Exercise of Options 

Unless specified otherwise in each relevant Option Agreement, the Options shall be capable of being exercised in whole or in part in
accordance with the following vesting schedule: 
  

			
	 Percentage of the Option:
	  	 will become exercisable on:

		
	25%	  	the first year anniversary of the Grant Date;
		
	6.25%	  	the last day of each three month period following the first year anniversary of the Grant Date and ending on the fourth year anniversary of the Grant Date.

 Deviations from the above vesting schedule are allowed to be made by the CEO only and will be subject to
the prior approval of the Compensation Committee. 
  

	7.4	Term and expiration of Options 

 Unless provided otherwise in each relevant Option Agreement, the Options granted to a Participant shall immediately expire upon the occurrence of any of the following events: 

 

	 	7.4.1	the eighth year anniversary of the Grant Date; 

	 	7.4.2	termination of the Participant’s employment for Cause, in which event the provisions of Article 7.8 shall apply; 

 

	 	7.4.3	occurrence of any of the events set out in Article 8.2. 

  

	 	7.4.4	(as further detailed in article 7.9) all unvested options shall expire upon the Participant no longer being an Employee, Advisor, or Board Member.

Option will expire or has expired. 
  

	7.5	Exercise 

 A Participant
may exercise his Options on the terms set out in the relevant Option Agreement by delivering an unconditional notice to the Company in accordance with the provisions of the Option Agreement. A Participant shall be entitled to exercise his Options
subject to compliance with the tax and social security withholding requirements imposed by the Company and/or the relevant Group Company pursuant to Article 11. The Options are exercised on the first day the Shares are traded following receipt
by the Company of the unconditional notification. If the Participant has requested the Company to sell the Shares, the Participant agrees that the Company will sell such Shares “at best price” for the risk and account of the Participant.

event of the Participant’s death, the Options held by a Participant shall be transferable to the Participant’s beneficiaries only by last will and testament or by the applicable laws of descent and distribution. Any other assignment or
transfer shall be deemed to be null and void and Options allegedly so assigned or transferred shall lapse with immediate effect. 
  

	7.7	Death of Participant / Total and Permanent Disability of Participant 

 If a Participant, dies or ceases to be an Employee, Advisor or Board Member as a consequence of Total and Permanent Disability, any Option granted to such Participant which is vested at the day the
Participant dies or ceases to be an Employee, Advisor or member of the Board and any Option granted to such Participant that would have vested during the twelve months following the day the Participant died or ceased to be an Employee, Advisor or
Board Member, may be exercised at any time thereafter during the eighteen months following the day the Participant died or ceased to be an Employee, Advisor or Board Member by the Participant’s beneficiaries or the Participant respectively,
unless the Option Agreement provides otherwise. 
  

	7.8	Termination for Cause 

 If
a Participant ceases to be an Employee, Advisor or Board Member for Cause, all Options held by him whether vested or non-vested, exercised or not, will be immediately cancelled. If such Participant has exercised (part of) his Options within two
months prior to the date on which the notice of termination was made by the Company or the relevant Group Company, the relevant Participant shall be required to repay to the Company an amount equal to the difference between: (i) the amount
received upon selling the Shares (which were acquired by exercising the relevant Options); and (ii) the Purchase Amount initially paid upon exercising the Options, unless the Compensation Committee, in its absolute discretion, decides
otherwise. The amount so to be repaid shall not be reduced by any taxes or social security charges due by the Participant in respect of the Options that are exercised. 

	7.9	Other termination events 

  

	 	7.9.1	If the Participant ceases to be an Employee, Advisor or Board Member respectively for reasons other than Cause, all Options of a Participant that have vested on
or prior to the date of termination can be exercised for a period of ninety days following the date of termination. 

  

	 	7.9.2	All Options of Participants that have not vested on or prior to the date of termination shall lapse on the date on which the Participant ceases to be an
Employee, Advisor or Board Member, unless decided otherwise by the Compensation Committee. For the purposes of this Article 7.9, a Participant shall continue to be considered an Employee, Advisor or Board Member if he is on military leave, sick
leave or other bona fide leave of absence. 

  

	7.10	Rights as a holder of Shares 

 A Participant shall have no rights as a holder of Shares until the date on which such Shares shall have been issued to the Participant. No adjustments and exceptions shall be made in connection with
dividends (ordinary or extra-ordinary or whether in currency, securities, or other property), distributions or other rights accruing to holders of Shares prior to the date on which the relevant Shares have been acquired by the relevant Participant.

  

	7.11	Other Provisions 

 Each
Option Agreement shall contain such other provisions as are deemed desirable by the CEO provided that any provisions which deviate from this Plan shall require the prior approval of the Compensation Committee, including but not limited to:

  

	 	7.11.1	restrictions on the exercise of Options; 

  

	 	7.11.2	restrictions on continued ownership of Shares following termination of employment; 

 

	 	7.11.3	submission by the Participant of such forms and documents as the Company may reasonably require; and/or 

 

	 	7.11.4	procedures to facilitate payment of the Purchase Amount under any method permitted pursuant to Article 10 and the payment of withholding taxes and social
security charges in accordance with Article 11. 

  

	8	Corporate Reorganisation 

  

	8.1	Recapitalisation 

Notwithstanding any other provision of this Plan but subject to the prior written approval of the Compensation Committee and any other
shareholder approval required pursuant to the Company’s Articles, agreements binding on the Company and applicable legislation, the CEO shall be allowed (but for the avoidance of doubt not obliged) to make adjustments to the class and number of
Shares to which this Plan applies, to the number of Shares to which each Option may entitle a Participant, to the Exercise Price of Options and/or any other aspect of this Plan in each case to prevent dilution or appreciation of the rights of
Participants in connection with any increase or reduction of Shares which were issued without the Company receiving adequate consideration in exchange, such as (but not limited to) the payment of a Common Stock dividend, a stock split, a reverse
stock split, a re-capitalisation, a combination, or reclassification or any other similar event. Upon any such adjustments being made, fractions of a Share shall not be issued but shall either be paid to the Participant in cash at Fair Market Value
or shall be rounded down or up to the nearest Share. In any event, the Exercise Price shall not be reduced below the nominal value of Shares but may be decreased or increased in proportion to any adjustment made as aforesaid. 

	8.2	Dissolution, liquidation, sale of assets, merger, split change in control, share-for-share exchange 

Notwithstanding any other provision of this Plan (but subject to the prior written approval of the Compensation Committee and any other
approval required pursuant to the Company’s Articles, agreements binding on the Company and applicable legislation) upon the Company’s dissolution, liquidation, sale of all or substantially all of its assets, merger, split, consolidation,
the occurrence of a similar event relating to the Company or in the event of a change of control or share-for-share exchange, the CEO shall have the power to: 
  

	 	8.2.1	cancel each outstanding Option (whether vested or not vested) immediately prior to such event. If the consideration is higher than the Exercise Price, this will
be done against payment of an amount in cash for each cancelled Option equal to the difference between the value of the consideration (including cash) received by holders of Shares in connection with such event and the Exercise Price to be paid by
such holders; or 

  

	 	8.2.2	exchange each outstanding Option (vested or not vested) immediately prior to such event by an alternative option entitling the holder thereof to the
consideration against which Shares are exchanged in connection with such event and, as a result, make any necessary equitable adjustment in the exercise price of the new option and/or the number of Shares to which the alternative option will entitle
the holders thereof or, as appropriate, provide for a cash payment to the Participant to whom such Option was granted in partial consideration for the exchange of the Option. 

 

	8.3	Limitation on rights of Participants 

 Except as expressly provided in this Article 8, no Participant shall be afforded any rights whatsoever by reason of any capital or corporate reorganisation of the Group. 

 

	8.4	No limitation on the rights of the Company 

 The grant of one or more Options pursuant to this Plan shall not in any way affect the rights or power of the Company to effect any capital or corporate reorganisation. 

 

	9	Amendment or Termination of this Plan 

 Subject to the prior approval of the Compensation Committee and any other shareholder approval or approval from another corporate body or other requirement pursuant to the Company’s Articles,
agreements binding on the Company and applicable legislation, the CEO may revise, amend, suspend or terminate this Plan in whole or in part including, without limitation, the adoption of any amendment deemed necessary or desirable to have the
Options comply with and be aligned to the rules and regulations imposed on the Company by a recognised stock exchange and to correct any inconsistency, defect or omission in the Plan or in any Option granted pursuant to this Plan. 

	10	Payment of the Purchase Amount 

  

	10.1	All cash payments due for Shares acquired pursuant to this Plan shall be made by bank transfer and shall be made in Euros, net of any transfer fees.

  

	11	Tax, Social Security and other fees

 All applicable personal tax and social security levies due in respect of this Plan, as well as legal and professional fees incurred by the Company or the Participant upon and in relation to the exercise
of an Option, shall be borne by the Participant. 
  

	11.2	Withholding of equivalent tax amount 

 Upon Options being granted or exercised and/or Shares being issued or sold to a third party, the Company and/or the relevant Group Company may require the Participant (prior to the Options being granted
and/or Shares being issued or sold) to remit to the Company and/or the Group Company an amount sufficient to satisfy all withholding tax and social security changes due in connection with such grant or exercise of Options and/or issuance and sale of
Shares. 
  

	11.3	Party bearing risk for legislative change 

 If further tax and/or social security levies become payable after the Options have been granted as a result of changes in tax and/or social security legislation, the costs and risks arising out of such
changes shall be borne by each relevant Participant.

under, this Plan as a result of such termination.
