Annual General Meeting 2003

Item 6: Capital reduction

6.1. Cancellation of shares repurchased under the 2002/2003 and 2002 b share buyback programs and respective amendment of article 4 of the Articles of Association

A. Motion
The Board of Directors proposes that 67,700,000 shares repurchased under the buyback program approved by the 2002 AGM and 8,270,080 shares repurchased under an additional buyback program approved by the Board of Directors, therefore a total of 75,970,080 shares, be cancelled and the share capital of the Corporation accordingly reduced by CHF 60,776,064.

Article 4 of the Articles of Association shall be amended as follows:

B. Explanations
The AGM on 18 April 2002 authorized the Board of Directors to buy back UBS shares in a maximum amount of CHF 5 billion via a second trading line on the virt-x exchange and subsequently to cancel them. Until 8 October 2002 a total of 67,700,000 shares with an overall market value of CHF 4,999,258,226.95 were repurchased under this program. The average purchase price was CHF 73.84. On 27 September 2002, the Board of Directors decided to launch an additional buyback program. Until 5 March 2003 8,270,080 shares were purchased under this program via the second trading line on the virt-x exchange with an aggregate value of CHF 529,878,075.05 and an average purchase price of CHF 64.07. The Board of Directors now proposes to the AGM to approve the cancellation of the 75,970,080 shares repurchased and to reduce the share capital in article 4 of the Articles of Association accordingly.

Ernst&Young as Statutory Auditors have confirmed in a special audit report on behalf of the AGM that as at 31 December 2002 the claims of creditors were fully covered even after the reduction in capital and that the Bank has adequate liquidity.

6.2. Approval of a new 2003 / 2004 share buyback program

A. Motion
The Board of Directors proposes that the following resolution be approved:

“The Board of Directors shall be authorized to buy back a maximum amount of CHF 5 billion in UBS shares via a second trading line on the virt-x exchange. These shares are to be cancelled definitively and are not therefore regarded as own shares within the meaning of Article 659 of the Swiss Code of Obligations. The required amendment to the Articles of Association (reduction of share capital) will be submitted to the AGM in 2004 for approval.”

B. Explanations
Shares shall be repurchased for cancellation if the firm’s capitalization remains at its current high level. The Board of Directors again requests the AGM to authorize the repurchase of a maximum amount of CHF 5 billion in UBS shares. The new buyback program 2003/2004 was announced on 6 March 2003.

The Board of Directors has again decided to proceed in two stages, with shareholders taking the decision in principle at the first AGM and deciding on the definitive cancellation of the shares at the next AGM. By obtaining shareholders’ approval for the future cancellation of the repurchased shares, these shares no longer fall under the statutory limit of Swiss Company Law, which prohibits companies from holding more than 10% of their own shares. The proposed procedure provides greater flexibility, which UBS believes to be in the interests of efficient capital management and the ongoing trading activities of the Bank.

Ernst&Young Ltd. as Statutory Auditors have confirmed in a special audit report on behalf of the Board of Directors that the claims of creditors were fully covered even after this additional capital reduction and that the Bank has adequate liquidity.
