Furthermore, the Company proposes to the AGM to distribute € 4.00 (four Euro) per common share from the cash proceeds of the placement of the Company's 37,000,000 common shares of ASM Pacific Technology Ltd. To do this in a tax efficient manner, it is proposed that the distribution is effected as a repayment of capital to the shareholders by way of a reduction of the par value of the common shares. For that purpose, it is proposed to first increase the issued capital of the Company by increasing the par value of all common shares by amending Article 3 of the Articles of Association and subsequently, after the mandatory procedure has been followed, to decrease the issued capital of the Company by decreasing the par value of all common shares - with the same amount as the increase - by amending Article 3 of the Articles of Association.
