3. Explanation of the dividend and reservation policy (discussion item)
   The Company has formulated a dividend and reservation policy consistent with its current strategy. The Company's policy in this respect is not to distribute any profits in the near future and to add any such profits to the Company's reserves for purposes such as funding the development and expansion of the Company's business, making future investments, financing capital expenditures and enhancing the Company's liquidity position. If and when the Company does intend to distribute a dividend, such dividend may be distributed in the form of cash only or shares only, through a combination of the foregoing (cash and shares) or through a choice dividend (cash or shares), in each case subject to applicable law.

This proposal is based on the positive outcome of a thorough selection procedure performed by the Company and the supervisory board's approval of the terms of engagement proposed by EY for these services (including the scope of the audit, the materiality to be used and compensation for the audit). The main conclusion of the selection procedure is that, because of the importance of continuity of the audit activities, it is desirable to extend EY's current engagement as the Company's external auditor.
