Calculations and determinations will be made in the sole discretion of JPMS, as calculation agent, and may be potentially adverse to your interests as an investor in the notes. MANY ECONOMIC AND MARKET FACTORS WILL IMPACT THE VALUE OF THE NOTES - In addition to the closing price of one share of the Reference Stock on any day, the value of the notes will be impacted by a number of economic and market factors that may either offset or magnify each other including the actual and expected volatility in the closing price of the Reference Stock; time to maturity of the notes; the dividend rate of the Reference Stock; interest and yield rates in the market generally; a variety of economic, political, regulatory and judicial events; and the creditworthiness of JPMorgan Chase n Co. THE AUTOMATIC CALL FEATURE MAY FORCE A POTENTIAL EARLY EXIT - If the notes are automatically called, the amount of Contingent Interest Payments made on the notes may be less than the amount of Contingent Interest Payments that would have been payable if the notes were held to maturity, and, for each $1,000 principal amount note, you will receive $1,000 plus the Contingent Interest Payment applicable to the relevant Review Date. RISK OF THE CLOSING PRICE OF THE REFERENCE STOCK FALLING BELOW THE INTEREST BARRIER OR THE TRIGGER LEVEL IS GREATER IF THE CLOSING PRICE OF THE REFERENCE STOCKS IS VOLATILE - The likelihood of the closing price of one share of the Reference Stock falling below the Interest Barrier or the Trigger Level will depend in large part on the volatility of the closing price of the Reference Stock - the frequency and magnitude of changes in the closing price of the Reference Stock. YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS - The notes do not guarantee any return of principal. If the notes are not automatically called, we will pay you your principal back at maturity only if the Final Stock Price is greater than or equal to the Trigger Level. If the notes are not automatically called and the Final Stock Price is less than the Trigger Level, you will lose 1% of your principal amount at maturity for every 1% that the Final Stock Price is less than the Initial Stock Price. Accordingly, under these circumstances, you will lose more than 25% of your principal amount and could lose up to the entire principal amount of your notes. THE APPRECIATION POTENTIAL OF THE NOTES IS LIMITED, AND YOU WILL NOT PARTICIPATE IN ANY APPRECIATION IN THE PRICE OF THE REFERENCE STOCK - The appreciation potential of the notes is limited to the sum of any Contingent Interest Payments that may be paid over the term of the notes, regardless of any appreciation in the price of the Reference Stock, which may be significant. You will not participate in any appreciation in the price of the Reference Stock. Accordingly, the return on the notes may be significantly less than the return on a direct investment in the Reference Stock during the term of the notes. THE BENEFIT PROVIDED BY THE TRIGGER LEVEL MAY TERMINATE ON THE FINAL REVIEW DATE - If the Final Stock Price is less than the Trigger Level, the benefit provided by the Trigger Level will terminate and you will be fully exposed to any depreciation in the closing price of one share of the Reference Stock. Because the Final Stock Price will be determined based on the closing price on a single day near the end of the term of the notes, the price of the Reference Stock at the maturity date or at other times during the term of the notes could be greater than or equal to the Trigger Level. This difference could be particularly large if there is a significant decrease in the price of the Reference Stock during the later portion of the term of the notes or if there is significant volatility in the price of the Reference Stock during the term of the notes, especially on dates near the final Review Date. REINVESTMENT RISK - If your notes are automatically called, the term of the notes may be reduced to as short as three months and you will not receive any Contingent Interest Payments after the applicable Call Settlement Date. There is no guarantee that you would be able to reinvest the proceeds from an investment in the notes at a comparable return and/or with a comparable interest rate for a similar level of risk in the event the notes are automatically called prior to the maturity date. In particular, on June 21, 2012, Moody's Investors Services downgraded our long-term senior debt rating to "A2" from "Aa3" as part of its review of 15 banks and securities firms with global capital markets operations. Moody's also maintained its "negative" outlook on us, indicating the possibility of a further downgrade. In addition, on May 11, 2012, Fitch Ratings downgraded our long-term senior debt rating to "A+" from "AA-" and placed us on negative rating watch for a possible further downgrade, and Standard n Poor's Ratings Services changed its outlook on us to "negative" from "stable," indicating the possibility of a future downgrade. These downgrades may adversely affect our credit spreads and the market value of the notes. See "Risk Factors" in our annual report on Form 10-K for the year ended December 31, 2011. In addition, on July 13, 2012, we reported that we had reached a determination to restate our previously filed interim financial statements for the first quarter of 2012. The restatement relates to valuations of certain positions in the synthetic credit portfolio of our Chief Investment Office. We also reported, on July 13, 2012, management's determination that a material weakness existed in our internal control over financial reporting at March 31, 2012. The reported trading losses have led to heightened regulatory scrutiny, and any future losses related to these positions and the material weakness in our internal control over financial reporting 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 "Recent Developments" in the accompanying term sheet and Item 4.02(a) of our Current Report on Form 8-K dated July 13, 2012 for further discussion. We and/or our affiliates may also currently or from time to time engage in business with the issuer of the Reference Stock including extending loans to, or making equity investments in, the issuer of the Reference Stock or providing advisory services to the issuer of the Reference Stock. In addition, one or more of our affiliates may publish research reports or otherwise express opinions with respect to the issuer of the Reference Stock, and these reports may or may not recommend that investors buy or hold the Reference Stock. As a prospective purchaser of the notes, you should undertake an independent investigation of the Reference Stock issuer that in your judgment is appropriate to make an informed decision with respect to an investment in the notes. The risk considerations identified below are not exhaustive. Please see the accompanying term sheet and product supplement for a more detailed discussion of risks, conflicts of interest and tax consequences associated with an investment in the notes. THE ANTI-DILUTION PROTECTION FOR THE REFERENCE STOCK IS LIMITED AND MAY BE DISCRETIONARY - The calculation agent will make adjustments to the Stock Adjustment Factor for certain corporate events affecting the Reference Stock. However, the calculation agent will not make an adjustment in response to all events that could affect the Reference Stock. If an event occurs that does not require the calculation agent to make an adjustment, the value of the notes may be materially and adversely affected. You should also be aware that the calculation agent may make adjustments in response to events that are not described in the accompanying product supplement to account for any diluting or concentrative effect, but the calculation agent is under no obligation to do so or to consider your interests as a holder of the notes in making these determinations. LACK OF LIQUIDITY - The notes will not be listed on any securities exchange. JPMS 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 the notes easily. Because other dealers are not likely to make a secondary market for the notes, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which JPMS is willing to buy the notes. HEDGING AND TRADING IN THE REFERENCE STOCK - While the notes are outstanding, we or any of our affiliates may carry out hedging activities related to the notes, including in the Reference Stock or instruments related to the Reference Stock. We or our affiliates may also trade in the Reference Stock or instruments related to the Reference Stock from time to time. Any of these hedging or trading activities as of the pricing date and during the term of the notes could adversely affect our payment to you at maturity. It is possible that these hedging or trading activities could result in substantial returns for us or our affiliates while the value of the notes declines. THE NOTES DO NOT GUARANTEE THE PAYMENT OF INTEREST AND MAY NOT PAY ANY INTEREST AT ALL - The terms of the notes differ from those of conventional debt securities in that, among other things, whether we pay interest is linked to the performance of the Reference Stock. We will make a Contingent Interest Payment with respect to a Review Date only if the closing price of one share of the Reference Stock on that Review Date is greater than or equal to the Interest Barrier. If the closing price of one share of the Reference Stock on that Review Date is less than the Interest Barrier, no Contingent Interest Payment will be made with respect to that Review Date, and the Contingent Interest Payment that would otherwise have been payable with respect to that Review Date will not be accrued and subsequently paid. Accordingly, if the closing price of one share of the Reference Stock on each Review Date is less than the Interest Barrier, you will not receive any interest payments over the term of the notes. CREDIT RISK OF JPMORGAN CHASE n CO. - The notes are subject to the credit risk of JPMorgan Chase n Co., and our credit ratings and credit spreads may adversely affect the market value of the notes. Investors are dependent on JPMorgan Chase n 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
