Issue of USD 30,000,000.00 Zero Coupon Callable Note due 20 May 2043 issued under the Euro Note Programme

PART A - CONTRACTUAL TERMS

Terms used herein shall be deemed to be defined as such for the purposes of the Conditions set forth in the Base Prospectus dated 27 June 2012, the Base Prospectus Supplement dated 30 August 2012, the Base Prospectus Supplement dated 08 November 2012, the Base Prospectus Supplement dated 03 January 2013, the Base Prospectus Supplement dated 18 February 2013, the Base Prospectus Supplement dated 25 March 2013 and any Base Prospectus Supplements dated thereafter but prior to the Issue Date of the Notes which together constitute a base prospectus for the purposes of the Prospectus Directive (Directive 2003/71/EC) (the "Prospectus Directive"). This document constitutes the Final Terms of the Notes described herein for the purposes of Article 5.4 of the Prospectus Directive and must be read in conjunction with such Base Prospectus as so supplemented.

Full information on the Issuer and the offer of the Notes described herein is only available on the basis of the combination of these Final Terms and the Base Prospectus. The Base Prospectus and the supplemental Base Prospectus are available for viewing at the website of the Irish Competent Authority (www.centralbank.ie) and copies may be obtained from the offices of the Paying Agents, The Bank of New York Mellon, acting through its London Branch, One Canada Square, London E14 5AL, The Bank of New York Mellon (Luxembourg) S.A., Vertigo Building - Polaris, 2-4 rue Eugène Ruppert, L-2453, Luxembourg and The Bank of New York Mellon (Ireland) Limited, 4th Floor, Hanover Building, Windmill Lane, Dublin 2, Ireland.

An investment in the Notes is subject to the credit risk of UBS AG and the actual and perceived creditworthiness of UBS AG may affect the market value of the Notes.

Any Notes purchased by any person for resale may not be offered in any jurisdiction in circumstances that would result in the Issuer being obliged to register any further prospectus or corresponding document relating to the Notes in that jurisdiction.

No secondary market for the Notes currently exists, nor is one likely to develop. Noteholders should have the ability and intent to hold the Notes until their Maturity Date.

The Notes have not been, and will not be, registered under the United States Securities Act of 1933, as amended (the "Securities Act"), or any state securities laws in the United States and are being offered and sold outside the United States to non-US persons (as such terms are defined in Regulation S under the Securities Act ("Regulation S")) in reliance on the exemption from registration provided pursuant to Regulation S. Notes sold in reliance on Regulation S will initially be represented by one or more permanent

global notes in registered form without interest coupons (each, a "Regulation S Global Note"), deposited with or on behalf of a common depository for Euroclear or Clearstream. Beneficial interests in a Regulation S Global Note may be held only through Euroclear or Clearstream, except in the limited circumstances described in the Base Prospectus. Investors may hold their interests in a Regulation S Global Note directly through Euroclear or Clearstream, if they are participants in such systems, or indirectly through organizations which are participants in such systems.
