UBS: Repayment of Nominal Value / Stock Split UBS / Unaxis: Adjustment of Market Maker Obligations and Mistrade Ranges

On April 19, 2006, the annual general meeting of UBS decided on a repayment of nominal value of CHF 0.60 and a stock split at the ratio of 1:2. Consequently, one existing UBS stock will be divided into two new stocks of UBS.

Ex date for both transactions will be July 10, 2006.

As a consequence to both corporate actions, an adjustment to the Eurex option on shares of UBS (UBSN) as well as to the stock futures contract on UBS (UBSF) will become necessary.
This circular describes the adjustment procedure.

Effective August 1, 2006, Market Maker Obligations and Mistrade Ranges in options on UBS will be adjusted. Due to the current high volatility in Unaxis, the Minimum Quote Size in options on Unaxis will be reduced as of July 1, 2006.
