PRICING SUPPLEMENT (To Prospectus dated January 11, 2012 and Product Supplement dated March 7, 2013)

UBS AG $1,593,000 Return Notes

Linked to a Basket of Equities due March 26, 2014

Investment Description

UBS AG Return Notes (the Notes) are unsubordinated, unsecured debt securities issued by UBS AG (UBS) and are designed for investors who seek exposure to an equally weighted basket (the underlying basket) of common stocks (each, a basket equity), subject to an adjustment factor. If the price of the underlying basket declines during the term of the Notes or if the final basket price is not greater than the initial basket price by at least approximately 1.0101%, UBS will repay less than the full principal amount at maturity resulting in a loss of some or all of your investment. Investing in the Notes involves significant risks. The Notes do not pay interest. You may lose all or a significant portion of your principal amount. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of the Issuer. If UBS were to default on its payment obligations you may not receive any amounts owed to you under the Notes and you could lose your entire investment.

Features

o Adjustment Factor: The amount payable at maturity, if any, will reflect the performance of the basket equities, subject to a reduction by the adjustment factor. Because the adjustment factor reduces the payment at maturity, if the final basket price is not greater than the initial basket price by at least approximately 1.0101%, you will lose some or all of your investment in the Notes.

o Full Downside Market Exposure: If the underlying return is negative, investors will be exposed to the negative underlying return at maturity, along with the adjustment factor, resulting in a loss of principal. Investors could lose some or all of their initial investment. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of UBS.

NOTICE TO INVESTORS: THE NOTES ARE SIGNIFICANTLY RISKIER THAN CONVENTIONAL DEBT INSTRUMENTS. UBS IS NOT NECESSARILY OBLIGATED TO REPAY THE FULL PRINCIPAL AMOUNT OF THE NOTES AT MATURITY. THE NOTES CAN HAVE A DOWNSIDE MARKET RISK SIMILAR TO THE DECLINE IN THE UNDERLYING BASKET, WHICH CAN RESULT IN A LOSS OF ALL OR A SUBSTANTIAL PORTION OF YOUR INVESTMENT AT MATURITY. THIS MARKET RISK IS IN ADDITION TO THE CREDIT RISK INHERENT IN PURCHASING A DEBT OBLIGATION OF UBS. YOU SHOULD NOT PURCHASE THE NOTES IF YOU DO NOT UNDERSTAND OR ARE NOT COMFORTABLE WITH THE SIGNIFICANT RISKS INVOLVED IN INVESTING IN THE NOTES.

YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED UNDER KEY RISKS BEGINNING ON PAGE 5 AND UNDER RISK FACTORS BEGINNING ON PAGE PS-12 OF THE RETURN NOTES PRODUCT SUPPLEMENT BEFORE PURCHASING THE NOTES. EVENTS RELATING TO ANY OF THOSE RISKS, OR OTHER RISKS AND UNCERTAINTIES, COULD ADVERSELY AFFECT THE MARKET VALUE OF, AND THE RETURN ON, YOUR NOTES. YOU MAY LOSE SOME OR ALL OF YOUR INITIAL INVESTMENT IN THE NOTES.

Investment Timeline

INVESTING IN THE NOTES INVOLVES SIGNIFICANT RISKS. THE NOTES DO NOT PAY INTEREST. YOU MAY LOSE SOME OR ALL OF YOUR PRINCIPAL AMOUNT. ANY PAYMENT ON THE NOTES, INCLUDING ANY REPAYMENT OF PRINCIPAL, IS SUBJECT TO THE CREDITWORTHINESS OF THE ISSUER. IF THE ISSUER WERE TO DEFAULT ON ITS PAYMENT OBLIGATIONS, YOU MAY NOT RECEIVE ANY AMOUNTS OWED TO YOU UNDER THE NOTES AND YOU COULD LOSE YOUR ENTIRE INVESTMENT.

Key Risks

An investment in the Notes involves significant risks. Some of the risks that apply to the Notes are summarized here, but we urge you to read the more detailed explanation of risks relating to the Notes generally in the Risk Factors section of the Return Notes product supplement. We also urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the Notes.

Ø Risk of loss The Notes differ from ordinary debt securities in that the issuer will not necessarily repay the full principal amount of the Notes. The amount payable at maturity, if any, will reflect the performance of the underlying basket, subject to a reduction by the adjustment factor. Because the adjustment factor reduces the payment at maturity, if the final basket price is not greater than the initial basket price by at least approximately 1.0101%, you will lose some or all of your investment in the notes.

Ø The adjustment factor will diminish any positive underlying return of the underlying basket and magnify any negative underlying return of the underlying underlying basket If the underlying return is negative or is less than approximately 1.0101%, at maturity, you will lose some or all of your investment. In addition, the adjustment factor will diminish any positive return of the underlying basket and magnify any negative return of the underlying basket. For each 1% that the final basket price is greater than the initial basket price, the return on your investment will increase by less than 1%. In addition, for each 1% that the final basket price is less than the initial basket price, you will lose more than 1% of your investment in the Notes, provided that the payment at maturity will not be less than zero.

Ø No interest You will not receive any periodic interest payments on the Notes.

Ø Credit risk of UBS The Notes are unsubordinated, unsecured debt obligations of the issuer, UBS, and are not, either directly or indirectly, an obligation of any affiliate of UBS or any third party. Any payment to be made on the Notes, including any repayment of principal, depends on the ability of UBS to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of UBS may affect the market value of the Notes and, in the event UBS were to default on its obligations, you may not receive any amounts owed to you under the terms of the Notes and you could lose your entire initial investment.

Ø Market risk The price of any basket equity can rise or fall sharply due to factors specific to that basket equity and the issuer of such basket equity such as price volatility, earnings, financial conditions, corporate, industry and regulatory developments, management changes and decisions and other events, as well as general market factors, such as general stock market volatility and prices, interest rates and economic and political conditions.

Ø Owning the Notes is not the same as owning the basket equities The return on your Notes may not reflect the return you would realize if you actually owned the basket equities. For instance, you will not receive or be entitled to receive any dividend payments or other distributions during the term of the Notes, and any such dividends or distributions will not be factored into the calculation of the payment at maturity on your Notes. In addition, as an owner of the Notes, you will not have voting rights or any other rights that a holder of the basket equities may have.

Ø No assurance that the investment view implicit in the Notes will be successful It is impossible to predict whether and the extent to which the price of the underlying basket will rise or fall. There can be no assurance that the price of the underlying basket will rise above the initial basket price. The price of the underlying basket will be influenced by complex and interrelated political, economic, financial and other factors that affect the issuer(s) of the basket equities. You should be willing to accept the risks of owning equities in general and the basket equities in particular, and the risk of losing some or all of your initial investment.

Ø Changes in the prices of the basket equities may offset each other The Notes are linked to an equally weighted basket comprised of the basket equities. Where the market price of one or more of the basket equities appreciates, the market price of one or more of the other basket equities may not appreciate by the same amount or may even decline. Therefore, in determining whether the final basket price and the payment at maturity on the Notes, increases in the prices of one or more of the basket equities may be moderated, or offset, by lesser increases or declines in the prices of one or more of the other basket equities.

Ø The Notes are considered hold to maturity products. Generally, there is no liquid market for the Notes.

Ø There may be little or no secondary market for the Notes The Notes will not be listed or displayed on any securities exchange or any electronic communications network. There can be no assurance that a secondary market for the Notes will develop. UBS Securities LLC and other affiliates of UBS may make a market in the Notes, although they are not required to do so and may stop making a market at any time. The price, if any, at which you may be able to sell your Notes prior to maturity could be at a substantial discount from the issue price and to the intrinsic value of the product; and as a result, you may suffer substantial losses.

Ø Price of Notes prior to maturity The market price of the Notes will be influenced by many unpredictable and interrelated factors, including the price of the underlying basket; the volatility of the basket equities; the dividends paid on the basket equities; the time remaining to the maturity of the Notes; interest rates in the markets in general; geopolitical conditions and economic, financial, political and regulatory, judicial or other events; and the creditworthiness of UBS.

Ø Impact of fees on the secondary market price of the Notes Generally, the price of the Notes in the secondary market is likely to be lower than the issue price to public since the issue price to public included, and the secondary market prices are likely to exclude, commissions, hedging costs or other compensation paid with respect to the Notes.

Ø Potential UBS impact on price Trading or transactions by UBS or its affiliates in the basket equities and/or over-the-counter options, futures or other instruments with returns linked to the performance of the underlying basket may adversely affect the performance of the basket equities and, therefore, the market value of the Notes.

Ø Potential conflict of interest UBS and its affiliates may engage in business with the issuers of the basket equities or trading activities related to the underlying basket or any basket equity, which may present a conflict between the interests of UBS and you, as a holder of the Notes. There are also potential conflicts of interest between you and the calculation agent, which will be an affiliate of UBS. The calculation agent will determine the underlying return and the payment at maturity of the Notes based on the final basket price of the underlying basket on the final valuation date. The calculation agent can postpone the determination of the underlying return or the maturity date if a market disruption event occurs and is continuing on the final valuation date.

Ø Potentially inconsistent research, opinions or recommendations by UBS UBS and its affiliates publish research from time to time on financial markets and other matters that may influence the value of the Notes, or express opinions or provide recommendations that are inconsistent with purchasing or holding the Notes. Any research, opinions or recommendations expressed by UBS or its affiliates may not be consistent with each other and may be modified from time to time without notice. Investors should make their own independent investigation of the merits of investing in the Notes and the underlying basket to which the Notes are linked.

Ø Uncertain tax treatment Significant aspects of the tax treatment of the Notes are uncertain. You should consult your tax advisor about your own tax situation. See What Are the Tax Consequences of the Notes beginning on page 9.

Hypothetical Examples and Return Table of the Notes at Maturity

The examples and table below illustrate the Payment at Maturity for a $1,000.00 Note on a hypothetical offering of the Notes, with the following assumptions (amounts have been rounded for ease of analysis):

●	●
Investment Term:	Approximately 12 months
Initial Basket Price:	100.00
Range of Basket Performance:*	75% to -75%

** The underlying return excludes any cash dividend payments

Example 1 The price of the underlying basket increases 20.00% from the initial basket price of 100.00 to a final basket price of 120.00. The investor receives a payment at maturity of $1,188.00 per $1,000.00 principal amount of the Notes, representing a return on the Notes of 18.80%, calculated as follows:

$1,000.00 × [(1 + 20%) × 99%] = $1,188.00

Example 2 The price of the underlying basket increases 1.0101% from the initial basket price of 100.00 to a final basket price of 101.0101. The investor receives a payment at maturity of $1,000.00 per $1,000.00 principal amount of the Notes, representing a return on the Notes of 0.00%, calculated as follows:

$1,000.00 × [(1 + 1.0101%) × 99%] = $1,000.00

Example 3 The initial basket price and the final basket price are both 100.00. The investor receives a payment at maturity of $990.00 per $1,000.00 principal amount of the Notes, representing a return on the Notes of -1.00%, calculated as follows:

$1,000.00 × [(1 + 0.00%) × 99%] = $990.00

Example 4 The price of the underlying basket decreases 30.00% from the initial basket price of 100.00 to a final basket price of 70.00. The investor receives a payment at maturity of $693.00 per $1,000.00 principal amount of the Notes, representing a return on the Notes of -30.70%, calculated as follows:

$1,000.00 × [(1 + -30.00%) × 99%] = $693.00

Accordingly, if the final basket price is below the initial basket price or if the final basket price is not greater than the initial basket price by at least approximately 1.0101%, UBS will pay you less than the full principal amount, if anything, resulting in a loss on your investment. You may lose up to 100% of your principal.

What Are the Tax Consequences of the Notes?

The United States federal income tax consequences of your investment in the Notes are uncertain. Some of these tax consequences are summarized below, but we urge you to read the more detailed discussion in Supplemental U.S. Tax Considerations beginning on page PS-41 of the Return Notes product supplement and discuss the tax consequences of your particular situation with your tax advisor.

There are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as the Notes. Pursuant to the terms of the Notes, UBS and you agree, in the absence of a statutory or regulatory change or an administrative or judicial ruling to the contrary, to characterize your Notes as a pre-paid derivative contract with respect to the underlying index. If your Notes are so treated, you should generally not recognize any income or loss with respect to your Notes prior to their maturity, redemption, sale or exchange and you should generally recognize capital gain or loss upon the sale, exchange, redemption or maturity of your Notes in an amount equal to the difference between the amount you receive at such time and the amount you paid for your Notes. Such gain or loss should generally be long-term capital gain or loss if you have held your Notes for more than one year.

In the opinion of our counsel, Cadwalader, Wickersham & Taft LLP, it would be reasonable to treat your Notes in the manner described above. However, because there is no authority that specifically addresses the tax treatment of the Notes, it is possible that your Notes could alternatively be treated for tax purposes in a manner described under Supplemental U.S. Tax Considerations Alternative Treatments on page PS-43 of the product supplement.

The Internal Revenue Service, for example, might assert that you should be required to recognize taxable gain on any rebalancing, replacement, or rollover of the underlying index.

In 2007, the Internal Revenue Service released a notice that may affect the taxation of holders of the Notes. According to the notice, the Internal Revenue Service and the Treasury Department are actively considering whether the holder of an instrument similar to the Notes should be required to accrue ordinary income on a current basis, and they are seeking taxpayer comments on the subject. It is not possible to determine what guidance they will ultimately issue, if any. It is possible, however, that under such guidance, holders of the Notes will ultimately be required to accrue income currently and this could be applied on a retroactive basis. The Internal Revenue Service and the Treasury Department are also considering other relevant issues, including whether additional gain or loss from such instruments should be treated as ordinary or capital, whether foreign holders of such instruments should be subject to withholding tax on any deemed income accruals, and whether the special constructive ownership rules of Section 1260 of the Internal Revenue Code of 1986, as amended (the Code) should be applied to such instruments. Holders are urged to consult their tax advisors concerning the significance, and the potential impact, of the above considerations. Except to the extent otherwise required by law, UBS intends to treat your Notes for United States federal income tax purposes in accordance with the treatment described above and under Supplemental U.S. Tax Considerations beginning on page PS-41 of the Return Notes product supplement, unless and until such time as the Treasury Department and Internal Revenue Service determine that some other treatment is more appropriate.

Moreover, in 2013, the House Ways and Means Committee released in draft form certain proposed legislation relating to financial instruments. If enacted, the effect of this legislation generally would be to require instruments such as the Notes to be marked to market on as annual a basis with the all gains and losses to be treated as ordinary, subject to certain exceptions. You are urged to consult your tax advisor regarding the draft legislation and its possible impact on you.

Beginning in 2013, U.S. holders that are individuals, estates, and certain trusts will be subject to an additional 3.8% tax on all or a portion of their net investment income, which may include any gain realized with respect to the Notes, to the extent of their net investment income that when added to their other modified adjusted gross income, exceeds $200,000 for an unmarried individual, $250,000 for a married taxpayer filing a joint return (or a surviving spouse), or $125,000 for a married individual filing a separate return. U.S. holders should consult their tax advisors with respect to their consequences with respect to the 3.8% Medicare tax.

Under recently enacted legislation, individuals (and to the extent provided in future regulations, entities) that own specified foreign financial assets in excess of an applicable threshold may be required to file information with respect to such assets with their income tax returns, especially if such assets are held outside the custody of a U.S. financial institution. You are urged to consult your tax advisor as to the application of this legislation to your ownership of the Notes.

Non-United States Holders. Subject to the discussion below regarding Section 871(m) and FATCA, if you are not a United States holder, you should generally not be subject to United States withholding tax with respect to payments on your Notes or be subject to generally applicable information reporting and backup withholding requirements with respect to payments on your Notes if you comply with certain certification and identification requirements as to your foreign status including providing an IRS form W-8BEN. Gain from the sale or exchange of a Note or settlement at maturity generally will not be subject to U.S. tax unless such gain is effectively connected with a trade or business conducted by the non-U.S. holder in the United States or unless the non-U.S. holder is a non-resident alien individual and is present in the U.S. for 183 days or more during the taxable year of such sale, exchange or settlement and certain other conditions are satisfied.

Section 871(m) . Section 871(m) of the Code requires withholding (up to 30%, depending on the applicable treaty) on certain financial instruments to the extent that the payments or deemed payments on the financial instruments are contingent upon or determined by reference to U.S.-source dividends. Under proposed U.S. Treasury Department regulations, certain payments that are contingent upon or determined by reference to U.S. source dividends, including payments reflecting adjustments for extraordinary dividends, with respect to equity-linked instruments, including the Notes, may be treated as dividend equivalents. If enacted in their

current form, the regulations may impose a withholding tax on payments made on the notes on or after January 1, 2014 that are treated as dividend equivalents. In that case, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld. Further, Non-U.S. Holders may be required to provide certifications prior to, or upon the sale, redemption or maturity of the Notes in order to minimize or avoid U.S. withholding taxes.

Foreign Account Tax Compliance Act. The Foreign Account Tax Compliance Act (FATCA) was enacted on March 18, 2010, and imposes a 30% U.S. withholding tax on withholdable payments (i.e., certain U.S. source payments, including interest (and OID), dividends, other fixed or determinable annual or periodical gain, profits, and income, and on the gross proceeds from a disposition of property of a type which can produce U.S. source interest of dividends) and pass-thru payments ( i.e , certain payments attributable to withholdable payments) made to certain foreign financial institutions (and certain of their affiliates) unless the payee foreign financial institution agrees, among other things, to disclose the identity of any U.S. individual with an account of the institution (or the relevant affiliate) and to annually report certain information about such account. FATCA also requires withholding agents making withholdable payments to certain foreign entities that do not disclose the name, address, and taxpayer identification number of any substantial U.S. owners (or certify that they do not have any substantial United States owners) withhold tax at a rate of 30%. Under certain circumstances, a holder may be eligible for refunds or credits of such taxes.

Pursuant to final Treasury regulations published in the Federal Register on January 28, 2013, the withholding and reporting requirements will generally apply to certain withholdable payments made after December 31, 2013, certain gross proceeds on sale or disposition occurring after December 31, 2016, and certain pass-thru payments made after December 31, 2016. This withholding tax would not be imposed on withholdable payments pursuant to obligations that are outstanding on January 1, 2014 (and are not materially modified after December 31, 2013) or to pass-thru payments pursuant to obligations that are outstanding six months after final regulations regarding such payments become effective (and such obligations are not subsequently modified in a material manner). If, however, withholding is required as a result of future guidance, we (and any paying agent) will not be required to pay additional amounts with respect to the amounts so withheld.

Significant aspects of the application of FATCA are not currently clear and the above description is based on regulations and interim guidance. Investors should consult their own advisor about the application of FATCA, in particular if they may be classified as financial institutions under the FATCA rules.

Section 871(m) of the Code requires withholding (up to 30%, depending on the applicable treaty) on certain financial instruments to the extent that the payments or deemed payments on the financial instruments are contingent upon or determined by reference to U.S.-source dividends. Under proposed U.S. Treasury Department regulations, certain payments that are contingent upon or determined by reference to U.S. source dividends, including payments reflecting adjustments for extraordinary dividends, with respect to equity-linked instruments, including the Notes, may be treated as dividend equivalents. If enacted in their current form, the regulations may impose a withholding tax on payments made on the Notes on or after January 1, 2014 that are treated as dividend equivalents. In that case, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld. Further, Non-U.S. Holders may be required to provide certifications prior to, or upon the sale, redemption or maturity of the Securities in order to minimize or avoid U.S. withholding taxes.

Foreign Account Tax Compliance Act . Sections 1471 through 1474 of the Code (which are commonly referred to a FATCA ) generally impose a 30% withholding tax on certain payments, including pass-thru payments to certain persons if the payments are attributable to assets that give rise to U.S.-source income or gain. However, the Internal Revenue Service has recently issued final regulations extending the FATCA grandfathering date such that FATCA withholding tax would not apply to any payment made under obligations outstanding on January 1, 2014 (and not materially modified after December 31, 2013). If the Notes are not materially modified, FATCA withholding generally is not expected to be required on the Notes. If, however, withholding is required as a result of future guidance, we (and any paying agent) will not be required to pay additional amounts with respect to the amounts so withheld. Significant aspects of the application of FATCA are not currently clear and investors should consult their own advisors about the application of FATCA, in particular if they may be classified as financial institutions under the FATCA rules.
