5. SCOPE OF THE PLEDGE

5.1 This pledge shall be a continuing security, shall remain in force until expressly released in accordance with Clauses 8.1 or 8.2 and shall in particular not be discharged by reason of the circumstance that there is at any time no Secured Liability currently owing from the Pledgor to the Pledgee.

5.2 This pledge shall not be discharged by the entry of any Secured Liabilities into any current account, in which case this pledge shall secure any provisional or final balance of such current account up to the amount in which the Secured Liabilities were entered therein.

5.3 The Pledgee may at any time without discharging or in any way affecting this pledge (a) grant the Pledgor any time or indulgence, (b) concur in any moratorium of the Secured Liabilities, (c) amend the terms and conditions of the Secured Liabilities, (d) abstain from taking or perfecting any other security and discharge any other security, (e) abstain from exercising any right or recourse or from proving or claiming any debt and waive any right or recourse, and (f) apply any payment received from the Pledgor or for its account towards obligations of the Pledgor other than the Secured Liabilities secured hereby.

6. RIGHTS ATTACHING TO THE SHARES

6.1 Cash and non-cash returns on the Shares

(a) Any cash return on the Shares, irrespective of whether in the form of dividends, repayment of capital, scripts or otherwise, shall be paid exclusively to the Cash Account. Except as provided for in clause 6.1(b) below or unless agreed otherwise by the Pledgee, the Pledgee shall then apply such cash returns towards the Secured Liabilities. In the absence of Secured Liabilities currently due and payable, the Pledgee may, at its option, either refund the amount of such cash return to the Pledgor, or hold such amount as part of the Pledged Assets and hold it in pledge as collateral for the Secured Liabilities, provided in the latter case that the Pledgee shall credit the Pledgor with interest on such amount at the rate usually paid by the Pledgee on similar customer, any such interest becoming part of the Pledged Assets and being in turn subject to this Clause 6.1 as if it were a return on the Shares.

(b) The Pledgee hereby authorises the Pledgor to withdraw cash amounts standing to the credit of the Cash Account and representing cash Dividends provided the below conditions are met:

- 4 -

Execution version

(i) at the time of the withdrawal, no Enforcement Event has occurred,

(ii) any instruction to debit any such cash amount from the Cash Account can only be given, and any such cash debit may only be made, if a cash Dividend has actually been declared and paid by the Company and credited to the Collateral Account (“Eligible Dividend Amount”), and

(iii) such withdrawal or debit shall not exceed the Maximum Permitted Dividend Amount. “Maximum Permitted Dividend Amount” means in respect of a declared cash Dividend an amount equal to 7% of the closing price of a Share on the Exchange on the Business Day immediately preceding the related Ex-Dividend Date multiplied by the number of Shares held by the Pledgor at the time that the relevant cash Dividend was declared. The Pledgor and the Account Bank shall ensure that all Dividends from time to time to be paid or made by or on behalf of the Company in respect of any of the Shares shall directly be paid or credited to the Collateral Account. The Pledgor shall notify the Pledgee and the Account Bank of his intention to withdraw a cash amount standing to the credit of the Collateral Account representing cash Dividends at least two Business Days prior to the intended withdrawal date which notice shall contain (i) the proposed amount to be withdrawn and details of the components of the relevant Maximum Permitted Dividend Amount (it being understood that information in relation to the relevant closing price of the Shares shall be provided by the Pledgee to the Pledgor in accordance with the provisions of the Put Option Transaction) and (ii) a confirmation by the Pledgor that such withdrawal complies with the provisions of this Clause 6.1. b).

(c) Any return on the Shares other than a cash return, irrespective of whether in the form of dividend shares, bonus shares, shares allocated on the occasion of a partial division or otherwise, shall be delivered exclusively to the Collateral Account and shall be part of the Pledged Assets.

(d) In the event that any return on the Shares which, pursuant to paragraph (a), is payable or deliverable to the Pledgee shall entitle the Pledgor to a tax credit on account of withholding taxes, the Pledgor shall, forthwith upon the declaration of such return, pay to the Pledgee an amount equivalent to such tax credit and such amount shall be deemed a cash return on the Shares for the purposes of this Clause 6.1.

6.2 Voting rights

(a) Subject to paragraph (b) below, the Pledgor shall be entitled to exercise all voting rights on the Shares. The Pledgor shall exercise its voting rights in respect of the Shares in a manner consistent with the interests of the Pledgee. In particular, and unless agreed otherwise by the Pledgee, the Pledgor shall

cast his votes against any proposal for the liquidation, merger, split-up, conversion or bankruptcy of the Company, this being understood that the Pledgee will not unreasonably withhold its agreement for proposals for the merger, split-up or conversion of the Company.

(b) If an Enforcement Event has occurred and is continuing, however, the Pledgor shall cast the votes attaching to the Shares in accordance with the Pledgee’s instructions, which instructions the Pledgor shall promptly request.

(c) If an Enforcement Event has occurred and is continuing the Pledgor shall forthwith give the Pledgee a copy of any convening notice or agenda of general shareholders meetings of the Company, and shall give the Pledgee notice of any proposed written shareholders resolution at least fifteen days before its adoption. The Pledgor shall not, unless with the Pledgee’s prior consent, waive the right (whether statutory or in accordance with the Company’s statutes) to any notice period in respect of the convening of general shareholders meetings of the Company. This Clause 6.2(c) shall not apply, however, to shareholders meetings or written resolutions dealing exclusively with Routine Agenda Items.

6.3 Subscription rights

The shares resulting from the exercise of any subscription rights to which the Shares may be entitled shall be held in pledge by the Pledgee as collateral for the Secured Liabilities, shall be part of the Shares for the purposes of this Agreement, and shall be credited to the Collateral Account.

6.4 Contribution calls

The Pledgor shall forthwith pay up any contribution duly called in respect of the Shares.

7. ENFORCEMENT

7.1 The Pledgee shall be entitled to enforce the security created by this Agreement in accordance with the procedure set out in article 7, §2 of the Royal Decree No. 62 (ie pursuant to the rules of Belgian law and without the need of a prior authorization from the Belgian courts). Such enforcement may take place at any time upon or after the occurrence of an Enforcement Event, howsoever described, in connection with the Secured Liabilities and as long as such event of default shall be continuing.

7.2 Without prejudice to Clause 7.1, the Pledgee shall also be entitled (but shall have no obligation), upon the occurrence of an Enforcement Event and at any time as long as such event shall be continuing, to forfeit and appropriate all or part of the Pledged Assets and to apply the value thereof against the Secured Liabilities. For the purposes of this application, the value of the Shares shall be the market opening price of the Shares on the day of appropriation.

The valuation of the Pledged Assets referred to under clause 6.1 c), if any, shall be made in accordance with the above rules applied mutatis mutandis.

8.2 The Pledgee shall grant an express release of this pledge, without delay upon demand of the Pledgor, as soon as all Secured Liabilities shall have been finally discharged. Forthwith upon such release being granted, the Pledgee shall notify the Account Bank of the release of this pledge and authorise the Account Bank to transfer the Shares and the other Pledged Assets, if any, as the Pledgor may instruct.

8.3 The Pledgee shall, without delay upon demand of the Pledgor, grant an express release of the pledge over 200,000 Shares as soon as all obligations of the Pledgor under the May Put Option Transaction have been finally discharged. Forthwith upon such release being granted, the Pledgee shall notify the Account Bank of the release of this pledge and authorise the Account Bank to transfer the Shares the release of which has been authorised, as the Pledgor may instruct.

8.4 Any release of this pledge shall be null and void and without effect if any payment received by the Pledgee and applied towards satisfaction of all or part of the Secured Liabilities (a) is avoided or declared invalid as against the creditors of the maker of such payment, or (b) becomes repayable by the Pledgee to a third party, or (c) proves not to have been effectively received by the Pledgee.

9. PLEDGEE’S AND ACCOUNT BANK’S DUTIES

9.1 The Pledgee shall not be liable for any acts or omissions with respect to the Pledged Assets or the enforcement of this pledge, except in case of its gross negligence or wilful misconduct.

If any such expenses are borne by the Pledgee, the Pledgor shall on first demand reimburse the Pledgee therefor, and this reimbursement obligation shall be part of the Secured Liabilities.

9.2 The Account Bank may rely on any notice from the Pledgee to the effect that an Enforcement Event has occurred and is continuing, shall have no obligation whatsoever to enquire about or verify the same, and shall not be bound to have regard to any disagreement in this respect between the Pledgor and the Pledgee.
