JPMorgan Chase & Co. Contingent Absolute Return Autocallable Optimization Securities

$6,922,220 Linked to the SPDR^® S&P^® Homebuilders ETF due on September 5, 2013

Investment Description

Contingent Absolute Return Autocallable Optimization Securities are unsecured and unsubordinated debt securities issued by JPMorgan Chase & Co. ("JPMorgan Chase") (each, a "Security" and collectively, the "Securities") linked to the performance of a specific exchange-traded fund (the "Fund"). The Securities are designed for investors who believe that the price of one share of the Fund will remain flat or increase during the term of the Securities, or not close below the Trigger Price on the Final Valuation Date. If the Fund closes at or above the Initial Share Price (subject to adjustments, in the sole discretion of the calculation agent, in the case of certain events described in the accompanying product supplement no. UBS-7-I under "General Terms of Securities — Anti-Dilution Adjustments") on any Observation Date, JPMorgan Chase will automatically call the Securities and pay you a Call Price equal to the principal amount per Security plus a Call Return. The Call Return increases the longer the Securities are outstanding. If by maturity the Securities have not been called and the closing price of one share of the Fund closes at or above the Trigger Price on the Final Valuation Date, JPMorgan Chase will repay the principal amount plus pay you a return at maturity equal to the absolute value of the percentage decline in the price of one share of the Fund from the Trade Date to the Final Valuation Date (the "Contingent Absolute Return"). If by maturity the Securities have not been called and the Fund closes below the Trigger Price on the Final Valuation Date, the Contingent Absolute Return will not apply and JPMorgan Chase will repay less than the principal amount, if anything, resulting in a loss that is proportionate to the decline in the price of one share of the Fund from the Trade Date to the Final Valuation Date. Investing in the Securities involves significant risks. The Securities do not pay interest. You may lose some or all of your principal amount. The Contingent Absolute Return, and any contingent repayment of principal, apply only if you hold the Securities to maturity. Any payment on the Securities, including any repayment of principal, is subject to the creditworthiness of JPMorgan Chase. If JPMorgan Chase were to default on its payment obligations, you may not receive any amounts owed to you under the Securities and you could lose your entire investment.


Features	Key Dates
❑ Call Return: JPMorgan Chase will automatically call the Securities for a Call Price equal to the principal amount plus a Call Return if the closing price of one share of the Fund on any Observation Date is equal to or greater than the Initial Share Price. The Call Return increases the longer the Securities are outstanding. If the Securities are not called, investors will have the potential for downside equity market risk at maturity. ❑ Contingent Absolute Return at Maturity: If by maturity the Securities have not been called and the price of one share of the Fund closes at or above the Trigger Price on the Final Valuation Date, JPMorgan Chase will repay the principal amount plus pay the Contingent Absolute Return. If the price of one share of the Fund closes below the Trigger Price on the Final Valuation Date, the Contingent Absolute Return will not apply and JPMorgan Chase will repay less than the principal amount, if anything, resulting in a loss that is proportionate to the decline in the price of the Fund from the Trade Date to the Final Valuation Date. The Contingent Absolute Return, and any contingent repayment of principal, apply only if you hold the Securities until maturity. Any payment on the Securities, including any repayment of principal, is subject to the creditworthiness of JPMorgan Chase.	Trade Date		August 29, 2012

NOTICE TO INVESTORS: THE SECURITIES ARE SIGNIFICANTLY RISKIER THAN CONVENTIONAL DEBT INSTRUMENTS. JPMORGAN CHASE IS NOT NECESSARILY OBLIGATED TO REPAY THE FULL PRINCIPAL AMOUNT OF THE SECURITIES AT MATURITY, AND THE SECURITIES CAN HAVE DOWNSIDE MARKET RISK SIMILAR TO THE FUND. THIS MARKET RISK IS IN ADDITION TO THE CREDIT RISK INHERENT IN PURCHASING A DEBT OBLIGATION OF JPMORGAN CHASE. YOU SHOULD NOT PURCHASE THE SECURITIES IF YOU DO NOT UNDERSTAND OR ARE NOT COMFORTABLE WITH THE SIGNIFICANT RISKS INVOLVED IN INVESTING IN THE SECURITIES.

YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED UNDER "KEY RISKS" BEGINNING ON PAGE 5 AND UNDER "RISK FACTORS" BEGINNING ON PAGE PS-7 OF THE ACCOMPANYING PRODUCT SUPPLEMENT NO. UBS-7-I AND UNDER "RISK FACTORS" BEGINNING ON PAGE US-1-I OF THE ACCOMPANYING UNDERLYING SUPPLEMENT NO. 1 BEFORE PURCHASING ANY SECURITIES. EVENTS RELATING TO ANY OF THOSE RISKS, OR OTHER RISKS AND UNCERTAINTIES, COULD ADVERSELY AFFECT THE MARKET VALUE OF, AND THE RETURN ON, YOUR SECURITIES. YOU MAY LOSE SOME OR ALL OF YOUR INITIAL INVESTMENT IN THE SECURITIES.

Investor Suitability


The Securities may be suitable for you if, among other considerations: ♦ You fully understand the risks inherent in an investment in the Securities, including the risk of loss of your entire initial investment. ♦ You can tolerate a loss of all or a substantial portion of your investment and are willing to make an investment that may have the same downside market risk as an investment in the Fund. ♦ You believe the Fund will close at or above the Initial Share Price on one of the specified Observation Dates or will close at or above the Trigger Price on the Final Valuation Date. ♦ You understand and accept that you will not participate in any appreciation in the price of one share of the Fund and that your potential return is limited to the Call Return or, if the Securities have not been called, to the Contingent Absolute Return (as limited by the Trigger Price). ♦ You can tolerate fluctuations in the price of the Securities prior to maturity that may be similar to or exceed the downside price fluctuations of the Fund. ♦ You are willing to invest in the Securities based on the Call Return rate of 10.57% per annum. ♦ You do not seek current income from this investment and are willing to forgo dividends paid on the Fund. ♦ You are willing to invest in securities that may be called early or you are otherwise willing to hold such securities to maturity, a term of approximately 12 months. ♦ You accept that there may be little or no secondary market for the Securities and that any secondary market will depend in large part on the price, if any, at which J.P. Morgan Securities LLC ("JPMS"), is willing to trade the Securities. ♦ You are willing to assume the credit risk of JPMorgan Chase for all payments under the Securities, and understand that if JPMorgan Chase defaults on its obligations you may not receive any amounts due to you including any repayment of principal.		The Securities may not be suitable for you if, among other considerations: ♦ You do not fully understand the risks inherent in an investment in the Securities, including the risk of loss of your entire initial investment. ♦ You cannot tolerate a loss of all or a substantial portion of your investment and are unwilling to make an investment that may have the same downside market risk as an investment in the Fund. ♦ You require an investment designed to provide a full return of principal at maturity. ♦ You believe that the price of one share of the Fund will decline during the term of the Securities and is likely to close below the Trigger Price on the Final Valuation Date exposing you to the full negative Fund Return at maturity. ♦ You seek an investment that participates in the full appreciation in the price of one share of the Fund or that has unlimited return potential. ♦ You cannot tolerate fluctuations in the price of the Securities prior to maturity that may be similar to or exceed the downside price fluctuations of the Fund. ♦ You are not willing to invest in the Securities based on the Call Return rate of 10.57% per annum. ♦ You prefer the lower risk, and therefore accept the potentially lower returns, of fixed income investments with comparable maturities and credit ratings. ♦ You seek current income from this investment or prefer to receive the dividends paid on the Fund. ♦ You are unable or unwilling to hold securities that may be called early, or you are otherwise unable or unwilling to hold such securities to maturity, a term of approximately 12 months, or you seek an investment for which there will be an active secondary market. ♦ You are not willing to assume the credit risk of JPMorgan Chase for all payments under the Securities, including any repayment of principal.

The suitability considerations identified above are not exhaustive. Whether or not the Securities are a suitable investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisers have carefully considered the suitability of an investment in the Securities in light of your particular circumstances. You should also review carefully the "Key Risks" beginning on page 5 of this pricing supplement, "Risk Factors" in the accompanying product supplement no. UBS-7-I and "Risk Factors" in the accompanying underlying supplement no. 1-I for risks related to an investment in the Securities.

Investment Timeline

Trade Date		The closing price of one share of the Fund is determined, the Trigger Price is determined and the Call Return rate is set.



Quarterly		The Securities will be called if the closing price of one share of the Fund on any Observation Date is equal to or greater than the Initial Share Price. If the Securities are called, JPMorgan Chase will pay the Call Price for the applicable Observation Date: equal to the principal amount plus an amount based on the Call Return rate.

If the Securities have not been called and the Final Share Price is equal to or greater than the Trigger Price, JPMorgan Chase will pay an amount in cash equal to: $10 × (1 + Contingent Absolute Return) per Security If the Securities have not been called and the Final Share Price is less than the Trigger Price, the Contingent Absolute Return will not apply and JPMorgan Chase will repay less than the principal amount, if anything, resulting in a loss proportionate to the decline of the Fund; equal to a return of: $10 × (1 + Fund Return) per Security


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

What Are the Tax Consequences of the Securities?

You should review carefully the section entitled "Material U.S. Federal Income Tax Consequences" in the accompanying product supplement no. UBS-7-I. The following discussion, when read in combination with that section, constitutes the full opinion of our special tax counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of Securities.

Based on current market conditions, in the opinion of our special tax counsel it is reasonable to treat the Securities as "open transactions" that are not debt instruments for U.S. federal income tax purposes. Assuming this treatment is respected, the gain or loss on your Securities should be treated as short-term capital gain or loss unless you hold your Securities for more than a year, in which case the gain or loss should be long-term capital gain or loss, whether or not you are an initial purchaser of Securities at the issue price. However, the Internal Revenue Service (the "IRS") or a court may not respect this treatment of the Securities, in which case the timing and character of any income or loss on the Securities could be significantly and adversely affected. In addition, in 2007 Treasury and the IRS released a notice requesting comments on the U.S. federal income tax treatment of "prepaid forward contracts" and similar instruments, which might include the Securities. The notice focuses in particular on whether to require holders of these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by Non-U.S. Holders should be subject to withholding tax; and whether these instruments are or should be subject to the "constructive ownership" regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose an interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Securities, possibly with retroactive effect. Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the Securities, including possible alternative treatments and the issues presented by this notice.

Non-U.S. Holders - Additional Tax Consideration

Non-U.S. Holders should note that recently proposed Treasury regulations, if finalized in their current form, could impose a withholding tax at a rate of 30% (subject to reduction under an applicable income tax treaty) on amounts attributable to U.S.-source dividends (including, potentially, adjustments to account for extraordinary dividends) that are paid or "deemed paid" after December 31, 2012 under certain financial instruments, if certain other conditions are met. While significant aspects of the application of these proposed regulations to the Securities are uncertain, if these proposed regulations were finalized in their current form, we (or other withholding agents) might determine that withholding is required with respect to Securities held by a Non-U.S. Holder or that the Non-U.S. Holder must provide information to establish that withholding is not required. Non-U.S. Holders should consult their tax advisers regarding the potential application of these proposed regulations. If withholding is so required, we will not be required to pay any additional amounts with respect to amounts withheld.

Key Risks

An investment in the Securities involves significant risks. Investing in the Securities is not equivalent to investing directly in the Fund. These risks are explained in more detail in the "Risk Factors" section of the accompanying product supplement no. UBS-7-I and the "Risk Factors" section of the accompanying underlying supplement no. 1-I. We also urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Securities.

Risks Relating to the Securities Generally

♦	Your Investment in the Securities May Result in a Loss — The Securities differ from ordinary debt securities in that JPMorgan Chase will not necessarily repay the full principal amount of the Securities. If the Securities are not called and the closing price of one share of the Fund has declined below the Trigger Price on the Final Valuation Date, you will be fully exposed to any depreciation in the closing price of one share of the Fund from the Initial Share Price to the Final Share Price and JPMorgan Chase will repay less than the full principal amount at maturity, resulting in a loss that is proportionate to the negative Fund Return. Under these circumstances, the Contingent Absolute Return will not apply and you will lose 1% of your principal for every 1% that the Final Share Price is less than the Initial Share Price and could lose your entire initial investment. As a result, your investment in the Securities may not perform as well as an investment in a security that does not have the potential for full downside exposure to the Fund at maturity.
♦	The Contingent Absolute Return Applies Only If You Hold the Securities to Maturity — If you are able to sell your Securities in the secondary market prior to maturity, you may have to sell them at a loss relative to your initial investment even if the closing price of one share of the Fund is above the Trigger Price. If by maturity the Securities have not been called, JPMorgan Chase will repay you the full principal amount per Security plus the Contingent Absolute Return, unless the price of one share of the Fund closes below the Trigger Price on the Final Valuation Date. Under these circumstances, the Contingent Absolute Return will not apply and JPMorgan Chase will repay less than the principal amount, if anything, resulting in a loss that is proportionate to the decline in the price of one share of the Fund from the Trade Date to the Final Valuation Date. The Contingent Absolute Return and any contingent repayment of principal are based on whether the Final Share Price is below the Trigger Price and apply only if you hold your Securities to maturity.
♦	Limited Return on the Securities — If the Securities are called, your potential gain on the Securities will be limited to the Call Return regardless of the appreciation in the closing price of one share of the Fund, which may be significant. Because the Call Return increases the longer the Securities have been outstanding and your Securities can be called as early as the first quarterly Observation Date, the term of the Securities could be cut short and the return on the Securities would be less than if the Securities were called at a later date. In addition, if the Securities are not called, your potential return on the Securities will be limited by the Trigger Price. Because JPMorgan Chase will pay you the principal amount plus the Contingent Absolute Return at maturity only when the Securities are not called and only if the Final Share Price is greater than or equal to the Trigger Price, your return on the Securities in this scenario is limited by the Trigger

	Price. Furthermore, because the closing price of one share of the Fund at various times during the term of the Securities could be higher than on the Observation Dates and on the Final Valuation Date, you may receive a lower payment if the Securities are automatically called or at maturity, as the case may be, than you would have if you had invested directly in the Fund.
♦	The Probability That the Final Share Price Will Fall Below the Trigger Price on the Final Valuation Date Will Depend on the Volatility of the Fund — "Volatility" refers to the frequency and magnitude of changes in the price of one share of the Fund. Greater expected volatility with respect to the Fund reflects a higher expectation as of the Trade Date that the price of one share of the Fund could close below its Trigger Price on the Final Valuation Date of the Securities, resulting in the loss of some or all of your investment. In addition, that Call Return rate is set on the Trade Date and depends in part on this expected volatility. However, the Fund's volatility can change significantly over the term of the Securities. The price of one share of the Fund could fall sharply, which could result in a significant loss of principal.
♦	Credit Risk of JPMorgan Chase & Co. — The Securities are unsecured and unsubordinated debt obligations of the issuer, JPMorgan Chase & Co., and will rank pari passu with all of our other unsecured and unsubordinated obligations. The Securities are not, either directly or indirectly, an obligation of any third party. Any payment to be made on the Securities, including any repayment of principal, depends on the ability of JPMorgan Chase & Co. to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of JPMorgan Chase & Co. may affect the market value of the Securities and, in the event JPMorgan Chase & Co. were to default on its obligations, you may not receive any amounts owed to you under the terms of the Securities and you could lose your entire investment.

Recent events affecting us have led to heightened regulatory scrutiny, may lead to additional regulatory or legal proceedings against us and may adversely affect our credit ratings and credit spreads and, as a result, the market value of the Securities. See "Executive Overview — Recent Developments," "Liquidity Risk Management — Credit Ratings," "Item 4. Controls and Procedures" and "Part II. Other Information — Item 1A. Risk Factors" in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2012.

♦	Reinvestment Risk — If your Securities are called early, the holding period over which you would receive the per annum return of 10.57% could be as little as three months. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Securities at a comparable rate of return for a similar level of risk in the event the Securities are called prior to the maturity date.
♦	No Periodic Interest Payments — You will not receive any periodic interest payments on the Securities.
♦	Potential Conflicts — We and our affiliates play a variety of roles in connection with the issuance of the Securities, including acting as calculation agent and hedging our obligations under the Securities. In performing these duties, our economic interests and the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the Securities. In addition, our business activities, including hedging and trading activities, could cause our economic interests to be adverse to yours and could adversely affect any payment on the Securities and the value of the Securities. It is possible that hedging or trading activities of ours or our affiliates could result in substantial returns for us or our affiliates while the value of the Securities declines. Please refer to "Risk Factors — Risks Relating to the Securities Generally" in the accompanying product supplement no. UBS-7-I for additional information about these risks.
♦	Certain Built-In Costs Are Likely to Affect Adversely the Value of the Securities Prior to Maturity — While the payment on any Call Settlement Date or at maturity, if any, described in this pricing supplement is based on the full principal amount of your Securities, the original issue price of the Securities includes UBS's commission and the estimated cost of hedging our obligations under the Securities. As a result, and as a general matter, the price, if any, at which JPMS will be willing to purchase Securities from you in secondary market transactions, if at all, will likely be lower than the original issue price and any sale prior to the maturity date could result in a substantial loss to you. This secondary market price will also be affected by a number of factors aside from UBS's commission and our hedging costs, including those set forth under "Many Economic and Market Factors Will Impact the Value of the Securities" below. The Securities are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your Securities to maturity.
♦	Investing in the Securities Is Not Equivalent to Investing in the Fund or the Stocks Composing the Fund — Investing in the Securities is not equivalent to investing in the Fund or the stocks held by the Fund. As an investor in the Securities, you will not have any ownership interest or rights in the Fund or the stocks held by the Fund, such as voting rights, dividend payments or other distributions.
♦	Your Return on the Securities Will Not Reflect Dividends on the Fund or the Stocks Composing the Fund — Your return on the Securities will not reflect the return you would realize if you actually owned the Fund or the stocks held by the Fund and received the dividends on the Fund or those stocks. This is because the calculation agent will calculate the amounts payable to you on the Securities by reference to the closing price of one share of the Fund on the Observation Dates without taking into consideration the value of dividends on the Fund or the stocks held by the Fund.
♦	No Affiliation with the Fund or the Issuers of the Equity Securities Composing the Fund — We are not affiliated with the Fund or to our knowledge the issuers of the equity securities composing the Fund. We have not independently verified the information about the Fund or the issuers of the equity securities composing the Fund contained in this pricing supplement. You should make your own investigation into the Fund and the issuers of the equity securities composing the Fund. We are not responsible for the public disclosure of information by the Fund or the issuers of the equity securities composing the Funds, whether contained in SEC filings or otherwise.
♦	No Assurances that the Investment View Implicit in the Securities Will Be Successful — While the Securities are structured to provide potentially enhanced returns in a flat or bullish environment or potential absolute returns in a negative environment above the Trigger Price, we cannot assure you of the economic environment during the term or at maturity of your Securities and you may lose some or all of your investment at maturity.

♦	Lack of Liquidity — The Securities will not be listed on any securities exchange. JPMS intends to offer to purchase the Securities in the secondary market, but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Securities easily. Because other dealers are not likely to make a secondary market for the Securities, the price at which you may be able to trade your Securities is likely to depend on the price, if any, at which JPMS is willing to buy the Securities.
♦	Anti-Dilution Protection Is Limited — Although the calculation agent will adjust the Initial Share Price and Trigger Price for certain events affecting the Fund, the calculation agent is not required to make an adjustment for every event that can affect the Fund. If an event occurs that does not require the calculation agent to adjust the Initial Share Price and the Trigger Price, the market value of your Securities and the payment at maturity if not previously called may be materially and adversely affected.
♦	There Are Risks Associated with the Fund — Although shares of the Fund are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and a number of similar products have been traded on NYSE Arca and other securities exchanges for varying periods of time, there is no assurance that an active trading market will continue for the shares of the Fund or that there will be liquidity in the trading market. The Fund is subject to management risk, which is the risk that the investment strategies of the Fund's investment adviser, the implementation of which is subject to a number of constraints, may not produce the intended results. These constraints could adversely affect the market price of the shares of the Fund, and consequently, the value of the Securities.
♦	Differences Between the Fund and its Underlying Index — The Fund does not fully replicate its underlying index, and may hold securities not included in its underlying index. In addition, its performance will reflect additional transaction costs and fees that are not included in the calculation of its underlying index. All of these factors may lead to a lack of correlation between the Fund and its underlying index. In addition, corporate actions with respect to the sample of equity securities (such as mergers and spin-offs) may impact the variance between the Fund and its underlying index. Finally, because the shares of the Fund are traded on NYSE Arca and are subject to market supply and investor demand, the market value of one share of the Fund may differ from the net asset value per share of the Fund. For all of the foregoing reasons, the performance of the Fund may not correlate with the performance of its underlying index.
♦	Hedging and Trading in the Fund — While the Securities are outstanding, we or any of our affiliates may carry out hedging activities related to the Securities, including in the Fund or instruments related to the Fund. We or our affiliates may also trade in the Fund or instruments related to the Fund from time to time. Any of these hedging or trading activities as of the Trade Date and during the term of the Securities could adversely affect our payment to you at maturity if not previously called. It is possible that these hedging or trading activities could result in substantial returns for us or our affiliates while the value of the Securities declines.

♦	Potentially Inconsistent Research, Opinions or Recommendations by JPMS, UBS or Their Affiliates — JPMS, UBS or their affiliates may publish research, express opinions or provide recommendations that are inconsistent with investing in or holding the Securities, and that may be revised at any time. Any such research, opinions or recommendations may or may not recommend that investors buy or hold the Fund and could affect the value of the Fund, and therefore the market value of the Securities.
♦	Tax Treatment — Significant aspects of the tax treatment of the Securities are uncertain. You should consult your tax adviser about your tax situation.
♦	Potential JPMorgan Chase & Co. Impact on Market Price of the Fund — Trading or transactions by JPMorgan Chase & Co. or its affiliates in the Fund and/or over-the-counter options, futures or other instruments with returns linked to the performance of the Fund may adversely affect the market price of the Fund and, therefore, the market value of the Securities.
♦	Market Disruptions May Adversely Affect Your Return — The calculation agent may, in its sole discretion, determine that the markets have been affected in a manner that prevents it from properly determining the closing price of one share of the Fund on an Observation Date, determining if the Securities are to be automatically called, calculating the Fund Return or Contingent Absolute Return if the Securities are not automatically called and calculating the amount that we are required to pay you, if any, upon an automatic call or at maturity. These events may include disruptions or suspensions of trading in the markets as a whole. If the calculation agent, in its sole discretion, determines that any of these events prevents us or any of our affiliates from properly hedging our obligations under the Securities, it is possible that one or more of the Observation Dates and the applicable payment date will be postponed and your return will be adversely affected. See "General Terms of Securities — Market Disruption Events" in the accompanying product supplement no. UBS-7-I.
♦	Many Economic and Market Factors Will Impact the Value of the Securities — In addition to the value of the Fund and interest rates on any trading day, the value of the Securities will be impacted by a number of economic and market factors that may either offset or magnify each other and which are set out in more detail in product supplement no. UBS-7-I.

Risks Relating to the Securities Generally

♦

The SPDR^® S&P^® Homebuilders ETF Is Linked to the Performance of the Homebuilding Industry — All or substantially all of the equity securities held by the SPDR^® S&P^® Homebuilders ETF are issued by companies whose primary lines of business are directly associated with the residential homebuilding industry. As a result, the value of the Securities may be subject to greater volatility and be more adversely affected by a single economic, political or regulatory occurrence affecting this industry than a different investment linked to securities of a more broadly diversified group of issuers. In addition, the homebuilding industry is significantly affected by a number of factors in general and local economic conditions and real estate markets as well as by weather conditions, natural disasters and geopolitical events, including those described under "Risk Factors" in the accompanying underlying supplement no. 1-I. These factors could cause an upturn or a downturn in the homebuilding industry generally or regionally and could cause the value of the equity securities held by the SPDR^® S&P^® Homebuilders ETF and the price of the Index Fund to decline during the term of the Securities.

Hypothetical Examples

The examples below illustrate the hypothetical payment upon a call or at maturity under different hypothetical scenarios for a $10.00 Security on an offering of the Securities based on the following information (amounts have been rounded for ease of reference):


Principal Amount:	$10.00
Term:	Approximately 12 months (unless earlier called)
Initial Share Price:	$23.48
Call Return Rate:	10.57% per annum (or 2.643% per quarter)
Observation Dates:	Quarterly
Trigger Price:	$17.61 (which is 75.00% of the Initial Share Price)

Example 1 — Securities are Called on the First Observation Date


Closing Price at first Observation Date:	$25.83 (at or above Initial Share Price, Securities are called)
Call Price (per Security):	$10.255

Because the Securities are called on the first Observation Date, we will pay you on the Call Settlement Date a total Call Price of $10.2643 per $10.00 principal amount (2.643% return on the Securities).

Example 2 — Securities are Called on the Final Valuation Date


Closing Price at first Observation Date:	$21.13 (below Initial Share Price, Securities NOT called)
Closing Price at second Observation Date:	$18.78 (below Initial Share Price, Securities NOT called)
Closing Price at third Observation Date:	$21.13 (below Initial Share Price, Securities NOT called)
Closing Price at Final Valuation Date:	$24.65 (at or above Initial Share Price, Securities are called)

Call Price (per Security):	$11.057

Because the Securities are called on the Final Valuation Date, we will pay you on the Call Settlement Date (which coincides with the Maturity Date in this example) a total Call Price of $11.057 per $10.00 principal amount (10.57% return on the Securities).

Example 3 — Securities are NOT Called and the Final Share Price is above the Trigger Price


Closing Price at first Observation Date:	$21.13 (below Initial Share Price, Securities NOT called)
Closing Price at second Observation Date:	$18.78 (below Initial Share Price, Securities NOT called)
Closing Price at third Observation Date:	$21.13 (below Initial Share Price, Securities NOT called)
Closing Price at Final Valuation Date:	$21.13 (below Initial Share Price, but above Trigger Price, Securities NOT called)

Settlement Amount (per Security):	$10.00 × (1 + Contingent Absolute Return) $10.00 × (1 + 10%) $11.00

Because the Securities are not called and the Fund Return is -10%, but the Final Share Price is above or equal to the Trigger Price, at maturity we will pay you a total of $11.00 per $10.00 principal amount (a 10% return on the Securities).

Example 4 — Securities are NOT Called and the Final Share Price is below the Trigger Price


Closing Price at first Observation Date:	$21.13 (below Initial Share Price, Securities NOT called)
Closing Price at second Observation Date:	$18.78 (below Initial Share Price, Securities NOT called)
Closing Price at third Observation Date:	$21.13 (below Initial Share Price, Securities NOT called)
Closing Price at Final Valuation Date:	$11.74 (below Initial Share Price and Trigger Price, Securities NOT called)

Settlement Amount (per Security):	$10.00 × (1 + Fund Return) $10.00 × (1 + -50%) $5.00

Because the Securities are not called and the Final Share Price is below the Trigger Price, at maturity we will pay you a total of $5.00 per $10.00 principal amount (a 50% loss on the Securities).

The hypothetical returns and hypothetical payments on the securities shown above do not reflect fees or expenses that would be associated with any sale in the secondary market. If these fees and expenses were included, the hypothetical returns and hypothetical payments shown above would likely be lower.
