EXTRAORDINARY GENERAL MEETING

Agenda and proposed resolutions: The agenda and proposed resolutions of the extraordinary general shareholders' meeting of the company, which, as the case may be, can be amended at the meeting by the chairman of the board of directors, are as follows:

1. Submission of special reports

• (a) Submission of the explanatory note prepared by the board of directors in relation to the proposal to reduce the fractional value of the company's shares through a reduction of the company's share capital with allocation of the amount of the share capital reduction to the issue premium account
• (b) Submission of the special report of the board of directors in accordance with Article 604 of the Belgian Company Code in relation to the proposal to renew the powers of the board of directors under the authorised capital of the company

2. Reduction of the fraction value of the company's shares

Proposed resolution: The general shareholders' meeting decides to reduce the fractional value of the company's shares to EUR 2.65 per share and to resolve, in implementation hereof, as follows (whereby the amounts or numbers referred to in the sub-sections between square brackets shall be determined at the time of the approval of the proposed resolution in accordance with the proposal set out in such sub-sections):

• (a) Subject to the application of the provisions of Article 612 and 613 of the Belgian Company Code, the share capital of the company shall be reduced with such amount so that the amount of the resulting share capital shall be equal to the number of outstanding shares multiplied by EUR 2.65, and whereby the amount of the capital reduction shall be booked immediately to an unavailable issue premium account. As a result hereof, the share capital of the company shall be reduced to the number of outstanding shares at the time of the approval of the proposed resolution multiplied by EUR 2.65.
• (b) The capital reduction shall occur without cancellation of existing shares of the company, is to be borne by each of the existing shares in the same manner, and shall be fully imputed on the fiscal paid-up share capital. Following the capital reduction, each share will represent the same fraction of the company's share capital. As a result, the company's share capital shall amount to [the number of outstanding shares at the time of the approval of the proposed resolution multiplied by EUR 2.65], represented by [the number of outstanding shares at the time of the approval of the proposed resolution], whereby each share shall have a fractional value of EUR 2.65.
• (c) In accordance with Article 613 of the Belgian Company Code, no distribution to the shareholders of the issue premium so booked shall be permitted as long as the demands for additional collateral, as the case may be, by creditors who within a term of two months following the publication of the present resolution in the annexes to the Belgian Official Gazette have made a demand for additional collateral for receivables that came into existence prior to, and that have not yet matured at, the date of such

publication, have not been satisfied, unless such demands for additional collateral have been rejected by an enforceable ruling by a competent court of law.

• (d) The amount of the capital reduction will be booked as issue premium. This issue premium will be accounted for on the liabilities side of the company's balance sheet under its net equity. The account on which the issue premium will be booked shall, like the share capital, serve as the guarantee for third parties and can only be reduced on the basis of a lawful resolution of the general shareholders' meeting passed in the manner required for an amendment to the company's articles of association.
• (e) Article 5 of the company's articles of association shall be amended and restated to take into account the aforementioned capital reduction.
• (f) The general shareholders' meeting confirms that all existing and future issue premium created and reflected on the account issue premium shall be unavailable. In view hereof, the general shareholders' meeting decides to make the following amendments to the articles of association:
• (i) The title and provisions of the current Article 7 of the company's articles of association shall be amended and restated to read as follows:

"Article 7 – Issue Premium

All issue premiums booked will be accounted for on the liabilities side of the company's balance under its net equity. The account on which the issue premiums are booked shall, like the share capital, serve as the guarantee for third parties and can only be reduced on the basis of a lawful resolution of the general shareholders' meeting passed in the manner required for an amendment to the company's articles of association."

(ii) The provisions of the current Article 7 of the company's articles of association prior to the amendment referred to in (i) shall be included in Article 6 (Nature of the Securities) of the company's articles of association by adding the following paragraph to this Article 6: "Unless otherwise provided by law, the transfer of securities is not subject to any restriction."

3. Reduction of the share capital

Proposed resolution: The general shareholders' meeting decides to reduce the share capital of the company through the distribution of an amount of EUR 0.15 per share to each of the outstanding shares (including the shares that prior to the Record Date (as defined below) will be issued upon the conversion of outstanding convertible bonds of the company), and to resolve, in implementation hereof, as follows (whereby the amounts or numbers referred to in the sub-sections between square brackets shall be determined at the time of the approval of the proposed resolution in accordance with the proposal set out in such sub-sections):

(a) Subject to the application of the provisions of Article 612 and 613 of the Belgian Company Code, and subject to the terms set out below, the share capital of the company shall be reduced with an amount equal to EUR 0.15 (the "Capital Reduction Amount"), multiplied by the sum of (i) all of the issued and outstanding shares of the company at the time of the approval of the present resolution, and (ii) all of the shares that as of the time of the approval of the present resolution until (and including) the Record Date can be issued upon conversion of the outstanding convertible bonds of the company that have been issued in 2009 (the "Convertible Bonds"). In implementation of the capital reduction, subject to the provisions set out below, an amount equal to the Capital Reduction Amount shall be distributed to each of the shares of the company that at the time of the approval of the present resolution is issued and outstanding, as well as to each share that as of the time of the approval of the present resolution until (and including) the Record Date shall be issued upon conversion of the outstanding Convertible Bonds.

• (b) The capital reduction shall occur without cancellation of shares of the company, is to be borne by each of the existing shares (including the shares that as of the time of the approval of the present resolution until (and including) the Record Date shall be issued upon the conversion of outstanding Convertible Bonds) in the same manner, and shall be fully imputed on the fiscal paid-up share capital. Following the capital reduction, each share (including the shares that as of the time of the approval of the present resolution until (and including) the Record Date shall be issued upon the conversion of outstanding Convertible Bonds) will represent the same fraction of the company's share capital.
• (c) In accordance with Article 613 of the Belgian Company Code, no distribution to the shareholders in implementation of the capital reduction shall be permitted as long as the demands for additional collateral, as the case may be, by creditors who within a term of two months following the publication of the present resolution in the annexes to the Belgian Official Gazette have made a demand for additional collateral for receivables that came into existence prior to, and that have not yet matured at, the date of such publication, have not been satisfied, unless such demands for additional collateral have been rejected by an enforceable ruling by a competent court of law.
• (d) In view of the provisions of paragraphs (a) to (c), the maximum amount of the capital reduction shall be equal to EUR [amount], being the sum of (i) the Capital Reduction Amount multiplied by all of the issued and outstanding shares of the company at the time of the approval of the present resolution (i.e. [amount]), and (ii) the Capital Reduction Amount multiplied by the maximum number of shares issuable at the time of the approval of the present resolution upon conversion of the Convertible Bonds at the conversion price applicable as at that time (i.e. [amount]). To the extent no new additional shares are issued upon conversion of Convertible Bonds prior to the end of the Record Date, the reduction of the share capital for an amount equal to the Capital Reduction Amount multiplied by the number shares issuable upon conversion of Convertible Bonds as reflected in point (ii) shall subsequently not be deemed made with respect to the number of new shares that are not so issued due to the fact that no such conversion of Convertible Bonds took place. The actual amount of the capital reduction shall become final on the Record Date, taking into account the shares that since the date of the present resolution until (and including) the Record Date shall have been actually issued upon conversion of the aforementioned outstanding Convertible Bonds, and taking into account that the amount to be distributed to each share outstanding on the Record Date shall be equal to the Capital Reduction Amount.
• (e) In view of the provisions of paragraphs (a) to (d), article 5 of the company's articles of association shall be amended at the time of the approval of the present resolution by reflecting a capital reduction equal to [the Capital Reduction Amount multiplied by all of the issued and outstanding shares of the company at the time of the approval of the present resolution], and by adding a separate paragraph with the sub-heading "Temporary provision" to article 5 that makes a reference to the provisions of paragraphs (a) to (d). Furthermore, until and including the Record Date, each time new shares are issued upon conversion of the Convertible Bonds, the amount of the share capital in article 5 shall be amended to take into account the amount of the share capital increase resulting from the conversion and the amount of the aforementioned capital reduction. The separate paragraph with the sub-heading "Temporary provision" to article 5 shall automatically expire and be deleted on the Record Date.
• (f) The general shareholders' meeting decides to authorize the board of directors (with power of substitution) to implement and execute the aforementioned capital reduction, including the power to determine the Record Date and the payment date of the distribution of the capital reduction in accordance with applicable legislation and

regulations, as well as the formalities for the distribution of the capital reduction. The "Record Date" for the capital reduction shall be the last trading day (prior to the payment date of the Capital Reduction Amount) on which the company's shares shall still trade "cum right" in relation to the right to receive the payment of the Capital Reduction Amount. The board of directors shall have the right to sub-delegate the exercise of the powers referred to in this paragraph (f) (in whole or in part) to one or two directors. Furthermore, the general shareholders' meeting decides to authorize one or two members of the board of directors in order to, as soon as reasonably and practicably possible after the Record Date, take all steps and carry out all formalities that shall be required to amend the articles of association in order to reflect the new share capital pursuant to paragraph (d).

4. Renewal of the powers of the board of directors under the authorised capital

Proposed resolution: Subject to the approval of the capital reduction referred to in item 2 of the agenda, the general shareholders' meeting resolves to amend and renew the powers of the board of directors within the framework of the authorised capital as follows (whereby the amount and date referred to in the sub-sections between square brackets shall be determined at the time of the approval of the proposed resolution in accordance with the proposal set out in such sub-sections):

This authorisation shall be valid for a period of five years as from the date of publication in the annexes to the Belgian State Gazette of an extract of the minutes of the extraordinary shareholders' meeting granting the authorisation, and shall otherwise have the terms and conditions as currently set out in Article 9 of the company's articles of association.
• (b) In view of the resolution set out in paragraph (a), Article 9 of the company's articles of association shall be amended and be restated to read as follows:

The board of directors may increase the capital by contributions in cash or in kind, by capitalisation of reserves, whether available or unavailable for distribution, with or without the issuance of new shares. The board of directors may use this authorisation for the issuance of the securities mentioned in article 11 below.

This authorisation is valid for a period of five years as from the date of publication in the Annex to the Belgian State Gazette of an extract of the minutes of the extraordinary shareholders' meeting of the company held on [the date of the approval of the proposed resolution].

In the event of a capital increase decided by the board of directors pursuant to the authorised capital, all issue premiums booked, if any, will be accounted for on the liabilities side of the company's balance under the net equity. The account on which the issue premiums are booked shall, like the share capital, serve as the guarantee for third parties and can only be reduced on the basis of a lawful resolution of the general shareholders' meeting passed in the manner required for an amendment to the company's articles of association.

In accordance with article 10 below, the board of directors may, in the interest of the company, restrict or cancel the preferential subscription right, including in favour of one or more specific persons other than employees of the company or of its subsidiaries."
