[completed on General Meeting date] by the end of July 2012 (“first Partial Par Value reduction”); (2) for the second partial par value reduction from chf [completed on General Meeting date] by chf [aggregate reduction amount divided by four] to chf [completed on General Meeting date] by the end of september 2012 (“second Partial Par Value reduction”); (3) for the third partial par value reduction from chf [completed on General Meeting date] by chf [aggregate reduction amount divided by four] to chf [completed on General Meeting date] by the end of december 2012 (“third Partial Par Value reduction”); and (4) for the fourth partial par value reduction from chf [completed on General Meeting date] by chf [aggregate reduction amount divided by four] to chf [completed on General Meeting date] by the end of March 2013 (“fourth Partial Par Value reduction”).

(ii) the aggregate distribution amount pursuant to paragraph 1 shall be adjusted as follows: sum of the four (Quarterly distribution amounts (adjusted pursuant to paragraph 4(i)) x number of shares registered in the commercial register of the canton of Zurich as issued and outstanding on the date of the registration of the respective Partial Par Value reduction).
