#### Disclosures on share capital
Issued share capital is divided into Series A shares and Series B shares. All such shares are nominative, have no par value and are fully issued, subscribed and paid.

Series B shares may not exceed 50% of the total issued, subscribed and paid-in shares of the Company and have a limited voting right, in that all of them can only elect one director of the Company, regardless of their equity interest and preferences:

(a) require the calling of an Ordinary or Extraordinary Shareholders' Meeting when requested by Series B shareholders representing at least 5% of the issued shares thereof; and

(b) require the calling of an extraordinary meeting of the board of directors, without the president being able to qualify the need for such a request, when so requested by the director who has been elected by the shareholders of said Series B.
