Annual General Meeting 2001

Item 8: Share split

A. Proposal
The Board of Directors proposes that the par value of the shares be reduced in a three-for-one split and that the number of shares be increased accordingly. Articles 4 and 4a will be amended to reflect this. The resolution will be adopted subject to the express condition that the revised Article 622 paragraph 4 of the Swiss Code of Obligations comes into force.

B. Explanations
The new provision of Article 622 paragraph 4 of the Code of Obligations allows a further reduction in the par value of the shares. Following the proposed three-for-one split, the UBS share will have a par value of CHF 2.80 and a market value more in line with that of its global peer group. UBS expects the lower market value to enhance the tradability and liquidity of the stock.
