Hypothetical Returns Hypothetical Range of Returns The following table illustrates the hypothetical Index Return for each Component Index and the corresponding Component Return for each Basket Component. Each hypothetical Index Return and Component Return set forth below assumes an Initial Index Level of 3,250, 9,280 and 9.344 for the EURO STOXX 50([R]) Index, the FTSE[] 100 Index and the TOPIX([R]) Index, respectively (based on a hypothetical closing level on the pricing date of 2,500, 5,800 and 730 for the EURO STOXX 50([R]) Index, the FTSE[] 100 Index and the TOPIX([R]) Index, respectively, and a hypothetical Exchange Rate on the pricing date of 1.30, 1.60 and 0.0128 for the EURO STOXX 50([R]) Index, the FTSE[] 100 Index and the TOPIX([R]) Index, respectively), and a Maximum Return of 17.90%, 17.90% and 17.90% for the Basket Components linked to the EURO STOXX 50([R]) Index, the FTSE[] 100 Index and the TOPIX([R]) Index, respectively. Each hypothetical Index Return and Component Return set forth below is for illustrative purposes only and may not be the actual Index Return and Component Return applicable to a purchaser of the notes. The numbers appearing in the following table have been rounded for ease of analysis. 275.000 Corresponding Graphs -3 Each graph below demonstrates the hypothetical Component Return applicable to an Index at maturity for a subset of Index Returns detailed for that Index in the table to the left. For example, the graph applicable to the 1,9 Euro STOXX 5 0([R]) represents 0.000 a subset of returns displayed in the first three columns in the table to the - left. None of these graphs, in isolation, reflect the payout formula applicable to your notes at maturity. Your investment may result in a loss of all of your principal at maturity.

Risk Considerations The risk considerations below are not considered exhaustive. Please see the accompanying term sheet for a more detailed discussion of risks, conflicts of interest, and tax consequences associated with an investment in the notes. YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS -- The notes do not guarantee any return of principal. The return on the notes at maturity is linked to the performance of the Component Indices and changes in the Exchange Rates and will depend on whether, and the extent to which, the Index Return of each Component Index is positive or negative. Your investment will be exposed to loss on a leveraged basis if the Ending Index Level for any Component Index is less than its Initial Index Level by more than 10%, including any decline caused by a change in the applicable Exchange Rate. Under these circumstances, you may lose some or all of your initial investment at maturity. CREDIT RISK OF JPMORGAN CHASE & CO. -- The notes are subject to the credit risk of JPMorgan Chase & Co., and our credit ratings and credit spreads may adversely affect the market value of the notes. Investors are dependent on JPMorgan Chase & Co.'s ability to pay all amounts due on the notes, and therefore investors are subject to our credit risk and to changes in the market's view of our creditworthiness. Any decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the value of the notes. If we were to default on our payment obligations, you may not receive any amounts owed to you under the notes 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 notes. 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. POTENTIAL CONFLICTS -- We and our affiliates may play a variety of roles in connection with the issuance of the notes, including acting as calculation agent and hedging our obligations under the notes. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the notes. It is possible that these hedging activities or other trading activities of ours or our affiliates could result in substantial returns for us or our affiliates while the value of the notes declines. THE COMPONENT RETURN FOR EACH BASKET COMPONENT IS LIMITED BY THE APPLICABLE MAXIMUM RETURN -- If the Ending Index Level of a Component Index is greater than its Initial Index Level, including any increase caused by a change in the applicable Exchange Rate, the Component Return for the Basket Component linked to such Component Index will not exceed a predetermined percentage, regardless of the appreciation in the applicable Component Index, which may be significant. Assuming a Maximum Return of 17.90% for each Basket Component, your payment at maturity will not exceed $1,179 for each $1,000 principal amount note. The actual Maximum Returns applicable to the Basket Components will be set on the pricing date and will not be less than 17.90% . A DECREASE IN THE VALUE OF THE COMPONENT CURRENCIES RELATIVE TO THE U.S. DOLLAR MAY ADVERSELY AFFECT YOUR RETURN ON THE NOTES -- The return on the notes is based on the performance of the Component Indices and changes in the Exchange Rates. The Ending Index Level of each Component Index is determined based on the Adjusted Closing Level of such Component Index, which is the closing level of such Component Index, converted into U.S. dollars based on the applicable Exchange Rate. Accordingly, any depreciation in the value of the Component Currencies relative to the U.S. dollar (or conversely, any increase in the value of the U.S. dollar relative to the Component Currencies) may adversely affect your return on the notes. CERTAIN BUILT-IN COSTS ARE LIKELY TO AFFECT ADVERSELY THE VALUE OF THE NOTES PRIOR TO MATURITY -- While the payment at maturity, if any, on the notes is based on the full principal amount of your notes, the original issue price of the notes includes the agent's commission and the estimated cost of hedging our obligations under the notes. As a result, and as a general matter, the price, if any, at which J.P. Morgan Securities LLC will be willing to purchase notes 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 the agent's commission and hedging costs, including those referred to under "Many Economic and Market Factors Will Impact the Value of the Notes" in the accompanying term sheet. MOVEMENTS IN THE LEVELS AND EXCHANGE RATES OF THE COMPONENT INDICES MAY BE HIGHLY CORRELATED -- Movements in the levels and Exchange Rates of the Component Indices may be highly correlated over the term of the notes. High correlation during periods of negative returns could have an adverse effect on your return on your investment at maturity. However, the movements in the levels and Exchange Rates of the Component Indices may become uncorrelated in the future. CHANGES IN THE VALUE AND EXCHANGE RATES OF THE COMPONENT INDICES MAY OFFSET EACH OTHER -- The notes are linked to a weighted Basket composed of the Basket Components, each of which is linked to a Component Index and each of which is converted into U.S. dollars. Price movements in the Component Indices may not correlate with each other. Therefore, in calculating the Basket Return, increases in the value of one or more of the Component Indices may be moderated, or more than offset, by lesser increases or declines in the level of one or more of the other Component Indices, particularly if the Component Indices that appreciate are of relatively low weight in the Basket. Similarly, movements in the Exchange Rates of the Component Indices may not correlate with each other. In addition, price movements in the Component Indices and movements in the Exchange Rates may not correlate with each other. At a time when the value or Exchange Rate of a Component Index increases, the Exchange Rate or value, respectively, of such Component Index may decline. Therefore, in calculating the Basket Return, increases in the value or Exchange Rate of a Component Index may be moderated, or more than offset, by declines in the Exchange Rate or value, respectively, of such Component Index. There can be no assurance that the Ending Index Level of each Component Index will be higher than the Initial Index Level of such Component Index. You may lose some or all of your investment in the notes if the Ending Index Levels of one or more Component Indices are lower than the Initial Index Levels of such Component Indices. THE NOTES ARE SUBJECT TO CURRENCY EXCHANGE RISK -- Foreign currency exchange rates vary over time, and may vary considerable and in unexpected ways during the term of the Notes. Changes in foreign currency exchange rates result over time from the interaction of many factors directly or indirectly affecting economic and political conditions in the underlying currencies' countries, and economic and political developments in other relevant countries. Of particular importance to potential currency exchange risk are existing and expected rates of inflation and interest rate levels, balance of payments in the underlying currencies' countries and between each country and its major trading partners, and the extent of government surplus or deficit in the underlying currencies' countries. NON-U.S. SECURITIES RISK -- The foreign equity securities included in the Component Indices have been issued by non-U.S. companies. Investments in notes linked to the value of such non-U.S. equity securities involve risks associated with the securities markets in those countries, including risks of volatility in those markets, governmental intervention in those markets and cross shareholdings in companies in certain countries. Also, there is generally less publicly available information about companies in some of these jurisdictions than about U.S. companies that are subject to the reporting requirements of the SEC, and generally non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements and securities trading rules different from those applicable to U.S. reporting companies. NO INTEREST OR DIVIDEND PAYMENTS OR VOTING RIGHTS -- As a holder of the notes, you will not receive any interest payments and you will not have voting rights or rights to receive cash dividends or other distributions or other rights that holders of securities composing the Component Indices would have. LACK OF LIQUIDITY -- The notes described above will not be listed on any securities exchange. J.P. Morgan Securities LLC intends to offer to purchase the notes 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 any notes issued by an issuer easily. Because other dealers are not likely to make a secondary market for such notes, prices for the notes described above in any secondary market are likely to depend on the price, if any, at which the issuer or the agent is willing to buy such notes. MANY ECONOMIC AND MARKET FACTORS WILL IMPACT THE VALUE OF THE NOTES -- In addition to the level of the underlying, the value of any notes that may be issued by an issuer described above will be affected by a number of economic and market factors that may either offset or magnify each other, including: the actual and expected volatility of the Component Indices; the time to maturity of the notes; the dividend rate on the equity securities that compose the Component Indices; interest and yield rates in the market generally; a variety of economic, financial, political, regulatory, and judicial events; and the creditworthiness of the issuer. The notes are not bank deposits and are not insured by the U.S. Federal Deposit Insurance Corporation or any other governmental agency, nor are they obligations of, or guaranteed by, a bank. Calculations and determinations will be made in the sole discretion of the calculation agent, JPMorgan Securities LLC, and may be potentially adverse to your interests as an investor in the notes.
