2. Annually as at the last day of each financial year the Management Board shall prepare the Company’s annual accounts (consisting of the balance sheet and profit and loss account with explanatory notes thereto) within five months of the end of each financial year, unless this period is extended by the General Meeting by no

more than five months due to extraordinary circumstances and it shall deposit the accounts at the Company’s offices for inspection by the shareholders and other Persons entitled to attend meetings. The Management Board shall also, within the above-mentioned period, deliver a directors’ report.

The annual accounts will be signed by all Managing Directors; if any signature should be lacking, this fact and the reasons therefore will be indicated in the annual accounts.

Company after the distribution will not be able to keep up paying its debts that are due.

4. No distribution of profits for the benefit of the Company will be made on shares owned by the Company.

5. For the calculation of the amount of the profit to be distributed on each share, only the amount of the obligatory payments on the nominal amount of the shares shall be taken into account. With consent of all shareholders each time this provision can be derogated from.

General Meeting:

Article 15:

1. During each financial year at least one General Meeting shall be held or at least once a resolution shall be adopted in accordance with paragraph 5 of this article, within six months after the end of the financial year, - except in case a delay in drawing up the annual accounts has been approved - which among others shall be dealt with:

If a shareholder or a Person entitled to attend meetings has consented thereto, notice for a General Meeting can also be given by electronic communication to the address provided for this purpose to the Company, provided the message is capable of being produced in writing.

3. Nevertheless, resolutions may be adopted by the General Meeting if no notice convening a meeting was made in accordance with paragraph 2 of this article, or if the item in question was not mentioned in the notice, provided all Persons entitled to attend meetings consent to the decision-making of these items and the Managing Directors prior to the decision-making have been given the opportunity to render advice.

4. The General Meeting is held in the place where the Company has its official seat, as well as in Rotterdam, Den Haag, Schiphol (municipality of Haarlemmermeer) and Utrecht. It may be held in a different place, provided all Persons entitled to attend meetings consent to the place of the meeting and the Managing Directors prior to the decision-making have been given the opportunity to render advice.

Article 16:

1. In as far as not provided for otherwise by law or these articles of association, all resolutions of the General Meeting shall be adopted by absolute majority of the votes.

2. Each share confers the right to cast one vote.

4. Winding-up of the Company shall be performed by the Management Board, unless the General Meeting decides otherwise.

5.

No winding-up dividend may be distributed to the Company itself on shares held by the Company.

6. After the liquidation has been completed, the books and records of the Company shall be kept for seven years by the person appointed for that purpose in the resolution of the General Meeting to dissolve the Company.
