UBS Share Repurchase Program (suspended)

During fourth quarter 2007, shares under 2007/10 program previously intended for cancellation were rededicated, and the program was suspended.

At the AGM on 18 April 2007, shareholders gave the BoD
a mandate to set up a repurchase program (2007 / 2010) for
a maximum amount of 10 % of shares totaling 210,527,328
shares. Between 14 March 2007 and 25 September 2007,
36.4 million shares in the total amount of CHF 2.6 billion were purchased for cancellation. As part of the capital measures
announced on 10 December 2007, the BoD has used
its discretion to rededicate for further use the 36.4 million
treasury shares previously intended for cancellation. At yearend,
no shares were held under the buyback program earmarked
for cancellation.
