Announcement by the board of directors of TVK Plc on adding items to the agenda of the 2008 Ordinary General Meeting of the company

The Board of Tisza Chemical Group Public Company Limited by Shares (3581 Tiszaújváros, TVK-Ipartelep, TVK Head Office, Lot number 2119/3 Building 136 Cg. 05-10-000065) hereby notifies its distinguished shareholders that the Company will add the following items to the agenda of its 2008 ordinary AGM convened for April 17, 2008 upon a request filed under Articles 217 and 300 of Act IV of 2006 on Economic Associations (the Company Act) by MOL Hungarian Oil and Gas Public Limited Company (head office: Budapest H-1117, Október huszonharmadika u. 18., Registration number: 01-10-041683), a shareholder holding directly and indirectly 94.86% of the shares of the Company:

5. Resolution on the option to discharge executive offices of their liability as provided in Section 30(5) of the Company Act

Shareholder MOL Hungarian Oil and Gas Public Limited Company offers the following proposed resolution and explanation to the new agenda item 5:

I. A resolution on this agenda item requires an amendment of Section 13 of the Articles of Association of the Company as part of the deliberations on agenda item 3 of the AGM.

Resolution proposed by MOL Plc. regarding the amendment of Section 13 of the Articles of Association and the related justification:

Section 30.§ (5) of the Company Act provides that the Articles of a Company may require the General Meeting to evaluate on an annual basis the work of executive officers in the previous business year, and to pass a resolution on discharging executive officers of their liability. By granting a discharge of liability, the General Meeting certifies that executive officers performed their work during the period under review by giving priority to the interests of the business association. The discharge of liability shall lose effect if a subsequent final court ruling declares the information underlying the discharge of liability false or insufficient.

Now, therefore shareholder MOL Plc. moves that the General Meeting should amend the Section 13 of the Articles of Association of the Company by altering the numbering of the section from the second sentence of the section to 13.1 and by adding a new section 13.2 as set out below:

Proposed Resolution:

Shareholder MOL Plc. proposes that the General Meeting of the Company should amend the Section 13 of the Articles of Association of the Company by altering the numbering of the section from the second sentence of the section to 13.1 and by adding a new section 13.2 as set out below:

“13.2. The General Meeting shall place on its annual agenda the evaluation of the work of executive officers in the previous business year and shall pass a resolution on discharging executive officers of their liability. By granting a discharge of liability, the General Meeting certifies that executive officers performed their work during the period under review by giving priority to the interests of the business association. The grant of discharge shall lose effect if a subsequent final court ruling declares the information underlying the discharge of liability false or insufficient.”

II. If the General Meeting decides to accept Section 13.2 of the Articles of Association as set out above, the GM may pass a resolution on granting a discharging of liability for the 2007 business year in a separate agenda item as proposed by MOL Plc.

The resolution proposed by shareholder MOL Plc. regarding that matter is laid out below:

Proposed Resolution:

Shareholder MOL Plc. proposes to the General Meeting to recognize and accept the work performed by the Board of Directors in the 2007 business year and to discharge directors of their liability as provided in section 30(5) of the Company Act.

Otherwise, the convocation of the General Meeting published on March 17, 2008 remains unchanged in every respect.
