---------------------------------------------------------------------------

The Executive Board of Deutsche Börse AG in consultation with the Working
Committee for Equity Indices today decided to make additions to the Guide
to Equity Indices effective as per 3 November 2008.

Thus, an index constituent can be removed from the selection indices DAX,
MDAX or SDAX outside the regular adjustment dates, if its weighting in the
index concerned on a trading day is over 10,0 percent at the end of trading
due to its current free-float market capitalization and if the stock chart
shows an annualized volatility over the course of the preceding 30 trading
days (30-days-volatility) of more than 250 percent. The applicable figures
are being published by Deutsche Börse AG on a daily basis. The decision to
take out index constituents prematurely is made by the Executive Board of
Deutsche Börse AG in consultation with the Working Committee for Equity
Indices. Removing will be done by the end of the second trading day after
the decision.

Companies which would drop out due to these rules can only be included
again, if their 30-days-volatility (annualized volatility of the stock over
a period of 30 trading days) at the particular call date of the making of
the ranking and on the 14 preceding days is each under 150 percent.
