"It is represented by [twenty nine million five hundred and fifty six thousand nine hundred twenty four] ([29.556.924]) shares without nominal value."

7. Renewal of the authorized capital

In respect of this agenda item, the board of directors has drafted a special report (art. 604 Companies' Code).

Proposed resolution:

Cancellation of the non-used balance of the authorized capital on the day of the publication of the decision and creation of a new authorized capital of fifty million (50.000.000) EUR for a term of five years.

Replace the current text of the fourth paragraph of Article 7 by the following text:

"According to the decision of the extraordinary general meeting of June 5th, 2012, the board of directors was granted the authority to increase the capital in one or more times, during the period and in the manner specified in the first three paragraphs of this article, up to a maximum amount of fifty million (50.000.000) EUR, exclusively within the frame of (i) capital increases reserved for the personnel of the company or of its affiliates, (ii) capital increases within the frame of the issue of warrants in favour of certain members of the personnel of the company or of its affiliates and, possibly, in favour of certain persons who are not part of the personnel of the company or of its affiliates, (iii) capital increases within the frame of an optional dividend, whether in this respect the dividend is directly distributed in the form of shares or is directly distributed in cash and afterwards the paid cash can be used to subscribe to shares, the case being by means of a surcharge and (iv) capital increases carried out by conversion of reserves or other entries of equity capital, so as to enable to round the amount of the capital to a convenient rounded amount."

while maintaining the current text of art. 8 (limitation or cancellation of the right of preference of existing shareholders) as follows:

"In the event of a capital increase by means of contribution of cash or in the event of issue of convertible bonds or of warrants, the general meeting may decide, in the interests of the company, to limit or cancel the existing shareholders' rights of preference.

The board of directors may also, for capital operations for which it has been granted authority within the frame of the authorized capital and in the interests of the company, decide to limit or cancel the existing shareholders' rights of preference, even if that limitation or cancellation is carried out in favour of one or more specific persons other than the personnel of the company or the personnel of one of the company's affiliates, insofar legally permitted."

8. Shares for personnel and capital increases

In respect of this agenda item, the board of directors and the statutory auditor have drafted a special report (art. 596 Companies' Code).

Proposed resolution:

Increase the capital of the company by a maximum amount of seven hundred and fifty one thousand two hundred and forty three (751.243 EUR) euro, through the issue of a maximum of one hundred and fifty thousand (150.000) new shares. These shares are to be of the same type as the existing VVPR shares, benefiting from the same rights and advantages, except that they will only share in potential profits as from the distribution of profits relating to the financial year started on January 1st, 2012.

These new shares will be subscribed and will be paid up in full in cash at par value, increased by an issue premium (to be decided), and will be offered for public subscription to the members of the Tessenderlo Group personnel.

The criteria, terms and conditions for the issuing and subscription of the new shares shall be as set out in the special report of the board of directors of March 28th, 2012, and the company capital shall be increased to the amount of the subscriptions made.

In the context of the aforesaid capital increase, cancel the shareholders' right of preference.

Increase the capital of the company a second time, to the extent deemed necessary, to round the amount of the capital to the nearest hundred thousand, by incorporation of all or part of the issue premiums resulting from the first capital increase, and also, where necessary, by incorporation of the necessary sum from available reserves, without issuing new shares.

Confer the powers necessary for carrying out the formalities and, in general, all that is necessary or useful for the execution of the decisions approved by the general meeting, and, especially, in order to have the number of newly subscribed shares, their payment in full, the realization of the relevant increase in capital, the incorporations which were made to achieve the end capital, and the adaptation of article 5 of the articles of association to the new situation of the company capital, authenticated in one or more times.

On the basis of the advice of the appointment and remuneration committee, the board of directors recommends to appoint Mr Guy de Gaulmyn as director, because of the professional skills of the latter as they are apparent from the below curriculum vitae.

Mr de Gaulmyn has amassed considerable experience in the chemistry industry, successively as Deputy Chief Executive Officer of the SNPE subsidiary Bergerac NC, as General Manager Chemicals and as Director Business Development Chemicals of the SNPE Group. In 2011, he joined Eurenco, a subsidiary of SNPE as Executive VP Additives. He currently holds the position of Chairman of Bergerac NC and of the joint venture companies of CNC in China and Korea. He is also Chairman of the Union of Chemical Industries of Ile de France and member of the board of directors of the French Chemical Industries Association. Mr de Gaulmyn graduated as an engineer from the Ecole Nationale Supérieure de Chimie of Toulouse (ENSIACET) and completed his education in management by a degree from the Institute of Management Control of Paris and then in strategy as an auditor of the Centre for Advanced Studies of Armament.

Proposed resolution:

The shareholders' meeting appoints Mr Guy de Gaulmyn as director for the remainder of the term of the mandate of Mr Schwartz, i.e. 3 years. His mandate will end after the shareholders' meeting approving the annual accounts for the financial year closed on December 31, 2014.

6. Approval of the US sub-plan relating to Warrant Plan 2011.

Proposed resolution:

The Warrant Plan 2011 of Tessenderlo Chemie NV, as amended and/or complemented by the "Sub-plan United States, Modifications to Plan 2011 for Residents of the United States", constitutes the US sub-plan relating to Warrant Plan 2011 (the "US Sub-plan"). For US purposes and to the extent necessary, the general meeting explicitly approves the US Sub-plan.

7. Approval of Warrant Plan 2012 and approval of change of control clauses relating thereto.

Proposed resolutions:

• a) The general meeting has been informed of the intention of the board of directors to issue, in 2012, warrants in the context of the authorized capital, which warrants will be granted to key employees of Tessenderlo Chemie NV. These warrants will be subject to the terms and conditions of the Warrant Plan 2012, the basic elements of which terms and conditions have been communicated to the general meeting and will be attached to the minutes. The members of the Group Management Committee are included in the group of potential beneficiaries. Taking into account the above, the general meeting approves the Warrant Plan 2012.
• b) In accordance with article 556 of the Belgian Companies' Code, the general meeting approves (i) the anti-dilution clauses in favour of Participants of the Warrant Plan 2012, (ii) each other clause of the aforesaid plan conferring rights to third parties which can have an influence on the patrimonium of Tessenderlo Chemie NV, or can create a debt or obligation for it, when the exercise of these rights is dependent on the launching of a public takeover bid on the shares of Tessenderlo Chemie NV or on a change of control over Tessenderlo Chemie NV as well as (iii) each operation done in execution of such clause. The anti-dilution clauses grant, in essence, the right to any warrant holder to immediately exercise their warrants in the event of a public takeover bid on the Tessenderlo Chemie NV shares or any other form of change of control. Such early exercise would allow warrant holders to take part in the above-mentioned operations at the same conditions as existing shareholders.

8. Digital registers of securities.

Proposed resolution:

The shareholders' meeting decides that all registers of securities held or to be held by the company, will be held in digital form.

(2) you must explicitly confirm to the company by Wednesday May 30th, 2012 that you wish to participate in these shareholders' meetings.

In order to meet these two conditions, shareholders are required to follow the below instructions:
