All or a portion of the notes may be redeemed by STATS at any time on or after
March 18, 2004 at a price to yield 4.91% per year to the redemption date if the
closing price of STATS' ordinary shares or ADSs is at least 125% of the
conversion price. Convertible note-holders may require STATS to repurchase all
or a portion of their convertible notes on March 18, 2005 at a price equal to
the principal amount of the convertible notes being redeemed together with a
premium of 10.081%, plus any accrued and unpaid interest accrued to the date of
redemption.
