7 TRANSFER OF SHARES AND SHARE TRANSFER RESTRICTIONS

7.1 Transfer of shares

Shares must be transferred by notarial deed.

7.2 Share transfer restrictions

A Transferor may transfer his shares after the management board has given its approval. This does not apply to the Company wanting to transfer shares.

7.3 Procedure

7.3.1 A Transferor requests approval for the transfer by notifying the management board. In this notification, the Transferor shall indicate:

(a) the number of shares he wants to transfer; and

(b) the persons who he wants to transfer those shares to.

7.3.2 The management board shall decide whether to grant its approval within forty-two days of receiving the notification referred to in article 7.3.1. If the management board does not come to a decision within that period, its approval will be deemed to have been granted.

7.3.3 If the management board refuses to grant its approval, it shall simultaneously designate one or more prospective purchasers who are willing to purchase the shares for cash. The price is determined in accordance with article 7.4.1. If the management board does not designate any prospective purchasers, its approval will be deemed to have been granted. The Company may only be a prospective purchaser if the Transferor agrees to this.

7.3.4 The Transferor may transfer the shares within ninety days after the approval has been granted or is deemed to have been granted.

7.4 Determining the price

7.4.1 The Transferor and each designated prospective purchaser shall consult each other to determine the price of the shares. If they fail to reach agreement, the price will be determined by an independent expert. The management board and the Transferor together designate the expert. If they fail to reach agreement on this, the expert will be designated by the chairman of the Royal Dutch Association of Civil-law Notaries (KNB).

7.4.2 After the expert has notified the Transferor of the price, the Transferor has thirty days to decide whether to transfer his shares to the prospective purchasers.

7.4.3 The costs of determining the price are paid by the Transferor.

7.5 Default

7.5.1 Each party may demand the transfer of the shares for cash immediately after the price has been determined in consultation or after the expiry of the period referred to in article 7.4.2, provided that neither the Transferor nor the prospective purchaser has withdrawn.

7.5.2 If there is only one prospective purchaser and that prospective purchaser has defaulted on payment, the Transferor may, within ninety days, transfer all the shares to the persons he has indicated as referred to in article 7.3.1 (b).

7.5.3 If there are multiple prospective purchasers and one of them has defaulted on payment, the Transferor shall notify all the prospective purchasers of that fact within seven days. The prospective purchasers who have not defaulted on payment will then have fourteen days to notify the Transferor whether they want to purchase the shares that had been allocated to the defaulting prospective purchaser. In doing so they shall indicate the maximum number of additional shares they would like to purchase. If all the shares that had been allocated to the defaulting prospective purchaser can be sold to the other prospective

purchasers, a purchase agreement will be concluded that is binding on the Transferor and the prospective purchasers. If no purchase agreement is concluded in this way for all these shares, any other purchase agreements will be deemed to have been terminated and the Transferor may, within ninety days, transfer all the shares to the persons he has indicated as referred to in article 7.3.1 (b).

7.5.4 If the Transferor defaults on the transfer of the shares, the Company is irrevocably authorised to transfer the shares. It shall do so within ten days of receiving such a request from a prospective purchaser.

If all managing director positions are vacant, that person shall as soon as possible take the necessary measures to make definitive arrangements. “Unable to act” means a managing director is temporarily unable to perform his duties as a result of:

(a) suspension;

(b) illness; or

(b) any damages or fines payable by them as a result of an act or failure to act as referred to under (a);

(c) the reasonable costs of appearing in other legal proceedings in which they are involved as current or former managing directors, with the exception of proceedings primarily aimed at pursuing a claim on their own behalf.

There shall be no entitlement to reimbursement as referred to above if and to the extent that (i) a Dutch court has established in a final and conclusive decision that the act or failure to act of the person concerned may be characterised as wilful (“opzettelijk”), intentionally reckless (“bewust roekeloos”) or seriously

culpable (“ernstig verwijtbaar”) conduct, unless Dutch law provides otherwise or this would, in view of the circumstances of the case, be unacceptable according to standards of reasonableness and fairness, or (ii) the costs or financial loss of the person concerned are covered by an insurance and the insurer has paid out the costs or financial loss. The Company may take out liability insurance for the benefit of the persons concerned. The managing board may by agreement or otherwise give further implementation to the above.

8.4.5 The management board may also adopt resolutions without holding a meeting, provided that these resolutions are adopted in writing or by reproducible electronic communication and all managing directors entitled to vote have consented to adopting the resolution outside a meeting. Articles 8.4.2 and 8.4.4 equally apply to adoption by the management board of resolutions without holding a meeting.

8.4.6 The General Meeting may make management board resolutions subject to its approval provided that those resolutions have been clearly specified and notified to the management board.
