4.2 The Board shall, with the prior approval of the Supervisory Board, have the authority, on behalf of the Company, to:

i) prescribe, amend and rescind rules and regulations relating to this Option Plan unless, with respect to any Option previously granted to the Participant and without his or her consent, such action would adversely materially affect the rights or position of the Participant in that respect;

ii) construe and interpret this Option Plan, any Option Agreement and any other agreement or document executed pursuant to this Option Plan;

iii) make all other determinations deemed necessary or desirable for the administration of this Option Plan.

4.3 The Board’s interpretation and construction of any provision of this Option Plan, of any Option granted under this Option Plan or of any Option Agreement shall be final and binding on all persons claiming an interest in an Option granted under this Option Plan. The Board, the Supervisory Board and/or the Company shall not be liable for any action or determination made in good faith with respect to this Option Plan. Without limiting the generality of the foregoing, the Board, the Supervisory Board and/or the Company shall not be liable to any Participant or to the estate or beneficiary of any

8

Participant or to any other holder of an Option granted under the Option Plan by reason of any acceleration of income, or any additional tax (including any interest and penalties), asserted by reason of the failure of an Option to satisfy the requirements of Sections 422 or 409A of the Code or by reason of Section 4999 of the Code, or otherwise asserted with respect to the Option.

Article 5. Eligibility and Participation

5.1 Employees, Directors, Supervisory Directors, consultants, but also other persons, in each case who are United States citizens or are otherwise subject to taxation in the United States, may become Participants to this Option Plan. The Board shall have complete discretion to select Participants (not being Supervisory Directors) who are eligible for participation, it being understood that such determination and granting of Options shall be subject to the prior approval of the Supervisory Board when it concerns the determination of eligible Employees, Directors, consultants and other persons not being Supervisory Directors. The GM shall have complete discretion to select the Supervisory Directors that are eligible for participation and to determine the size of their Grant. Options may be granted to a Participant upon the commencement of his/her engagement and/or may be granted on regular, periodical basis.

5.2 A Grant in one year does not create rights for future years. A Grant does not qualify as a term of employment for Employees and shall not be included in the calculation of any termination payment for an Employee. Neither this Option Plan nor the grant of Options under the Option Agreement shall confer upon the Participant any right to receive additional or future Options or similar rights.

5.3 This Option Plan shall not at any time affect the rights of the (shareholders of the) Company or a company within the Group to terminate such Participant’s status as an Employee, Director, Supervisory Director or consultant (whether with or without Cause).

Article 6. Shares

6.1 Options granted under this Option Plan shall be granted only on Shares.

6.2 The Shares acquired upon exercise of the Option may not and cannot, without the prior written approval of the Board and the Supervisory Board, be assigned or transferred, unless in accordance with or otherwise provided for in this Option Plan (for instance in case of death of the Participant) and/or the Option Agreement. The Shares may not be pledged, encumbered or otherwise used for the purpose of creating security title or interest of whatsoever nature, without the prior written approval of the Board, subject to the prior approval of the Supervisory Board.

9

Article 7. Granting, vesting and terms of Options

7.1 Subject to Article 4 and Article 5, Options shall be granted by the Board, subject to prior approval of the Supervisory Board or the GM, as the case may be, to the Participants.

7.2 Each Grant shall be evidenced by a written Option Agreement, setting forth the specific terms and conditions pertaining to such Option.

7.3 An Option starts Vesting on the Vesting Date as specified in the Option Agreement, and Vests in accordance with the following vesting scheme:

i) 25% of the Options granted at any moment shall have Vested upon the first anniversary of the Date of Grant; and

ii) the remaining 75% of the Options shall Vest with 2.083% per month and on a linear basis over a period of three years from the first anniversary of the Date of Grant (i.e. in total 50% upon the second anniversary of the Date of Grant and in total 62.5% six months after the second anniversary of the Date of Grant).

Should the Vesting result in an Option that entitles a Participant to a fraction of a Share, this fraction of a Share shall at the discretion of the Board, subject to the prior approval of the Supervisory Board either (i) be paid to the Participant in cash at fair market value, or (ii) be rounded down to the nearest number of Shares.

7.4 Notwithstanding Article 7.3, the unvested Options held by Participants (other than Supervisory Directors) shall at the sole discretion of the Supervisory Board in whole or in part become Vested upon the occurrence of a Liquidity Event, provided that the Participant on the date that the Liquidity Event occurs still qualifies as an Employee, Director, consultant and/or another capacity it has when it received its Options. Unvested Options held by Supervisory Directors shall at the sole discretion of the GM in whole or in part become Vested upon the occurrence of a Liquidity Event, provided that the Supervisory Director on the date that the Liquidity Event occurs still qualifies as a Supervisory Director.

7.5 Each Option Agreement shall state the Exercise Price for the Shares to which the Option pertains. The Exercise Price of each Option shall be at least the Fair Market Value of one Share on the Date of Grant; provided, that in the event that a Participant is a Ten Percent Stockholder, the Exercise Price of an Option granted to such Participant that is intended to be an Incentive Stock Option shall be not less than one hundred ten percent (110%) of the Fair Market Value of one Share on the Date of Grant.

10

7.6 Only Vested Options can be exercised within an Exercise Period. Once a year in the month June and in any event also upon the expected occurrence of a Liquidity Event, the Board shall inform all Participants in writing of the possibility to exercise any Vested Options. A Participant may exercise an Option by delivering an Exercise Notice to the Company. A Participant exercising an Option shall pay the Exercise Price in conformity with Article 9. Any Shares issuable upon the exercise of an Option shall be issued as soon as possible after the Board having received the duly executed Exercise Notice and in any event within 20 business days thereafter, provided the Exercise Price was paid by the respective Participant.

7.7 In the event of a Liquidity Event whereby a third party is involved, the Board may, with the prior approval of the Supervisory Board, decide that upon exercise of an Option by a Participant, the Shares will not be issued to the Participant against payment of the Exercise Price, but instead (i) the Option will be cancelled without issuance of Shares to the Participant on the condition that (ii) the Exercise Price is set off against the purchase price which purchase price the Participant would have received would he/she have sold his/her Shares to a third party in case of a Liquidity Event (the Purchase Price) whilst (iii) the balance of the Purchase Price and the Exercise Price for his/her Shares is transferred to a bank account in the name of the Participant as soon as reasonably possible.

The Board may, with the prior approval of the Supervisory Board, for reasons of efficiency (though at its sole discretion) decide to handle the exercise (including the Participant’s decision to exercise) of the Options in any alternative manner, provided however this alternative manner (i) does not materially adversely and financially affect the position of the Participant and (ii) is merely construed for cost or time-efficient, logistic and pragmatic reasons and does not negatively change the end result for the Participants e.g. the entitlement of the Participants to cash may not be converted into an entitlement to Shares.

7.8 An Option granted to a Participant is strictly personal and shall be exercisable only by the Participant and shall neither be assignable nor transferable, unless in in accordance with or otherwise provided for in this Option Plan (for instance in case of death of the Participant) and/or the Option Agreement. Any attempted assignment or transfer (not in accordance with or otherwise provided for in this Option Plan (for instance in case of death of the Participant) and/or the Option Agreement) shall be deemed to be null and void and the Option shall lapse with immediate effect.

7.9 A Participant shall not have the rights of holders of Shares, until the date of issuance of Shares to the Participant. No adjustment shall be made for dividends (ordinary or extraordinary or whether in currency, securities, or other property), distributions or other rights accruing prior to the date of issuance of the Shares to the Participant.

11

7.10 Each Option granted under the Option Plan shall terminate, and all rights to purchase Shares thereunder shall cease, on the day before the tenth (10th) anniversary of the Date of Grant of such Option, or under such circumstances and on such date prior thereto as is set forth in the Option Plan or as may be fixed by the Board, subject to the prior approval of the Supervisory Board, and stated in the Option Agreement relating to such Option; provided, that in the event that the Participant is a Ten Percent Stockholder, an Option granted to such Participant that is intended to be an Incentive Stock Option shall not be exercisable after the day before the fifth (5th) anniversary of the Date of Grant of such Option.

7.11 An Option Agreement may contain such other provisions as are deemed desirable by the Board provided these provisions are not inconsistent with the terms of this Option Plan, including but not limited to: restrictions on the exercise of Options, restrictions on the disposal of the Shares, restrictions on continued ownership of Shares following the date of termination of employment, submission by the Participant of such forms and documents as the Board may reasonably require, obligations for the Participant to mandatory sell the Shares to a third party in case of a Liquidity Event (drag along rights), and/or procedures to facilitate the payment of the Exercise Price of an Option.

7.12 An Option shall constitute an Incentive Stock Option only (a) if the Participant of such Option is an Employee, (b) to the extent specifically provided in the related Option Agreement, and (c) to the extent that the aggregate Fair Market Value (determined at the time such Option is granted) of the Shares with respect to which all Incentive Stock Options held by such Participant become exercisable for the first time during any calendar year (under the Option Plan and all other plans of the Company and its parent and subsidiary corporations (as defined in Section 424 of the Code)) does not exceed one hundred thousand dollars ($100,000). Except to the extent provided in the regulations under Section 422 of the Code, this limitation shall be applied by taking Options into account in the order in which they were granted.

12

Article 8. Internal Reorganisation, takeover, merger and liquidation

8.1 In the event of an internal reorganisation, recapitalisation or refinancing of the Company and/or companies of the Group, the Board, subject to the prior approval of the Supervisory Board, may make or cause to make any adjustments to the Options such as but not limited to: the class and/or number of Shares covered by this Option Plan, the number of Shares for which each outstanding Option pertains, the Exercise Price of an Option and/or any other aspect of this Option Plan.

8.2 All adjustments described in this Article 8 shall be made by the Board, subject to approval of the Supervisory Board, in its complete discretion, and such determination shall be conclusive and binding on all Participants.

8.3 The Grant of an Option pursuant to this Option Plan shall not affect in any way the right or power of the Company to effectuate an internal reorganisation, recapitalisation, merger, takeover, refinancing or liquidation of the Group.

Article 9. Payment of the Exercise Price

9.1 Payment of the Exercise Price for any Shares acquired pursuant to this Option Plan shall be made by the Participant via a bank transfer to the bank account of the Company or a third party bank account designated by the Board.

The Company or the Group may require the Participant to remit to the Company an amount sufficient to satisfy all withholding tax requirements (other than the withholding of personal tax and employee social security levies).

13

10.4 This Option Plan is governed by the applicable tax and social security legislation and regulations prevailing at the date of the adoption of this Option Plan by the Supervisory Board. If any tax and/or social security legislation or regulations are amended in the future and any tax or employee social security levies become payable, the costs and risks related thereto shall be borne by the Participant, unless otherwise decided by the Supervisory Board or the GM.

10.5 The Company shall be entitled to set off all taxes and employee social security levies as paid by the Company in connection with the exercise of any Option against any payment obligation it may have towards the Participants (such as the payment of the salary or management fee of the Participant).

10.6 The Participant indemnifies the Company and the Group for all of the Company and Group’s costs resulting from the fact that the Participant did not fully comply with its fiscal obligations in connection with the exercise of an Option, such as the payment of income tax (as far as applicable).

Article 11. Other Restrictions

13.2 Any other notice or communication to be provided under this Option Plan shall be deemed to have been delivered: (i) on the date of hand delivery to the parties’ addresses as specified in the Participant’s Option Agreement or at such other delivery addresses which have been provided, which delivery is evidenced by a receipt signed by the receiving party; or (ii) on the date of expedition by registered mail to the parties’ addresses as specified in the Participant’s Option Agreement or at such other mailing address which has been provided.

Article 14. Requirements of Law

The Company shall not be required to offer, sell, or issue any Shares under any Option, whether pursuant to the exercise of an Option or otherwise, if the offer, sale, or issuance of such Shares would constitute a violation by the Participant, the Company, any company within the Group or any other person, of any provision of applicable law. If at any time the Company shall determine, in its discretion, that the listing, registration, or qualification of any Shares subject to an Option upon any securities exchange or under any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the offering, issuance, sale, or purchase of Shares in connection with any Option, no Shares may be offered, issued, or sold to the Participant or any other person under such Option, whether pursuant to the exercise of an Option or otherwise, unless such listing, registration, or qualification shall have been effected or obtained free of any conditions not acceptable to the Company, and any delay caused thereby shall in no way affect the date of termination of such Option. Without limiting the generality of the foregoing, upon the exercise of any Option, unless a registration statement under the Securities Act of 1933, as amended (the Securities Act), is in effect with respect to the Shares subject to such Option, the Company shall not be required to offer, sell, or issue such Shares unless the Board, subject to the prior approval of the Supervisory Board, shall have received evidence satisfactory to it that the Participant or any other person exercising such Option may acquire such Shares pursuant to an exemption from registration under the Securities Act. Any determination in this connection by the Board shall be final, binding, and conclusive. The Company may register, but shall in no event be obligated to register, any Shares or other securities issuable pursuant to the Option Plan pursuant to the Securities Act. The Company shall not be obligated to take any affirmative action in order to cause the exercise of an Option or the issuance of Shares or other securities issuable pursuant to the Option Plan or any Option to comply with any applicable law. As to any jurisdiction that expressly imposes the requirement that an Option that may be settled in Shares shall not be exercisable or issued until the Shares subject to such Option are registered under the securities laws thereof or are exempt from such registration, the exercise of such Option and issuance of Shares pursuant to such Option under circumstances in which the laws of such jurisdiction apply shall be deemed conditioned upon the effectiveness of such registration or the availability of such an exemption.

16

Article 15. Conflict with Option Agreement

In case of a conflict between the provisions of an Option Agreement and this Option Plan, the provisions of the Option Agreement shall prevail.

Article 20. Parachute Limitations

If any Participant is a “disqualified individual” (as defined in Section 280G(c) of the Code), then, notwithstanding any other provision of the Option Plan or of any other agreement, contract, or understanding heretofore or hereafter entered into by such Participant with the Company or any company within the Group (an Other Agreement), and notwithstanding any formal or informal plan or other arrangement for the direct or indirect provision of compensation to the Participant (including groups or classes of Participants or beneficiaries of which the Participant is a member), whether or not such compensation is deferred, is in cash, or is in the form of a benefit to or for the Participant (a Benefit Arrangement), any right of the Participant to any exercise, vesting, payment, or benefit under the Option Plan shall be reduced or eliminated:

(a) to the extent that such right to exercise, vesting, payment, or benefit, taking into account all other rights, payments, or benefits to or for the Participant under the Option Plan, all Other Agreements, and all Benefit Arrangements, would cause any exercise, vesting, payment, or benefit to the Participant under the Option Plan to be considered a “parachute payment” within the meaning of Section 280G(b)(2) of the Code as then in effect (a Parachute Payment); and

(b) if, as a result of receiving such Parachute Payment, the aggregate after-tax amounts received by the Participant from the Company under the Option Plan, all Other Agreements, and all Benefit Arrangements would be less than the maximum after-tax amount that could be received by the Participant without causing any such payment or benefit to be considered a Parachute Payment.

Except as required by Section 409A of the Code or to the extent that Section 409A of the Code permits discretion, the Board shall have the right, in the Board’s sole discretion, to designate those rights, payments, or benefits that should be reduced or eliminated so as to avoid having such rights, payments, or benefits be considered a Parachute Payment; provided, however, to the extent any payment or benefit constitutes deferred compensation under Section 409A of the Code, in order to comply with Section 409A of the Code, the Board shall instead accomplish such reduction by first reducing or eliminating any cash payments (with the payments to be made furthest in the future being reduced first), then by reducing or eliminating any accelerated vesting of Options (with the vesting to occur furthest in the future being reduced first), then by reducing or eliminating any other remaining Parachute Payments.

Article 21. Section 409A

21.1 The Option Plan and Options granted thereunder are intended to be exempt from Section 409A of the Code, and, accordingly, to the maximum extent permitted, the Option Plan will be interpreted and administered to be exempt from Section 409A of the Code. Notwithstanding any provision of the Option Plan to the contrary, to the extent required to avoid accelerated taxation and tax penalties under Section 409A of the Code, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to the Option Plan during the six (6)-month period immediately following the Participant’s “separation from service” (as defined for purposes of Section 409A of the Code) will instead be paid on the first payroll date after the six (6)-month anniversary of the Participant’s separation from service (or the Participant’s death, if earlier).

18

21.2 To the extent that the Board determines that a Participant would be subject to the additional twenty percent (20%) tax imposed on certain nonqualified deferred compensation plans pursuant to Section 409A of the Code as a result of any provision of any Option granted under the Option Plan, such provision shall be deemed amended to the minimum extent necessary to avoid application of such additional tax. The nature of any such amendment shall be determined by the Board, subject to the prior approval of the Supervisory Board. Notwithstanding the foregoing, neither the Company, the Board nor the Supervisory Board will have any obligation to take any action to prevent the assessment of any excise tax or penalty on any Participant under Section 409A of the Participant, and neither the Company, any company within the Group, the Board nor the Supervisory Board will have any liability to any Participant for such tax or penalty.

Article 22. Governing Law. Competent Court

22.1 This Option Plan shall be governed by and construed in accordance with the laws of the Netherlands.

22.2 The district court in Amsterdam, the Netherlands shall have exclusive jurisdiction over a dispute arising out of or in connection with this Option Plan, as well as over any claims to demand performance under this Option Plan.
