7yr ETF Efficiente Contingent Annual Income Note Selected Benefits North America Structured Investments The Notes offer full return of principal at maturity, subject to the credit risk of JPMorgan Chase [AND] Co. The Notes will pay a coupon equal to at least the Minimum Interest Rate on an annual basis Minimum denominations of $10,000 and integral multiples of $1,000 in excess thereof The Index dynamically allocates among the following 12 ETFs (the "ETF Constituents") and the JPMorgan Cash Index USD 3 Month (the "Cash Constituent"), each a "Basket Constituent" ----------------------------------------------------------------------------------------- SPDR([R])S[AND]P 500([R])ETF iShares([R])Emerging Trust (SPY) Markets Bond Fund (EMB) SPDR([R])Gold Trust (GLD) ----------------------------------------------------------------------------------------- iShares([R])Russell 2000 iShares([R])Dow Jones Real iShares([R])Barclays TIPS Bond Index Fund (IWM) Estate Index Fund (IYR) Fund (TIP) ----------------------------------------------------------------------------------------- iShares([R])MSCI EAFE iShares([R])S[AND]P GSCI JPMorgan Cash Index USD 3 Index Fund (EFA) Commodity Indexed Month (JPCAUS3M) Trust (GSG) ----------------------------------------------------------------------------------------- ---------------------------------------------------- iShares([R])Barclays 20+Year iShares([R])MSCI Treasury Bond Fund (TLT) Emerging Markets Index Fund (EEM) ---------------------------------------------------- iShares([R])iBOXX $Investment Grade Corporate Bond Fund (LQD) ---------------------------------------------------- iShares([R])iBOXX$ High Yield Corporate Bond Fund (HYG) ---------------------------------------------------- Selected Risks For each Interest Determination Date, if the Cumulative Index Return is negative or less than the Minimum Interest Rate, your interest payment will equal the Minimum Interest Rate for that period. No guaranteed interest payment above the Minimum Interest Rate. Payment on the Notes at maturity, as well as any interest payment, is subject to our credit risk. Therefore the value of the Notes prior to maturity will be subject to changes in the market's view of our creditworthiness. Your aggregate interest payments may yield a lower return than the Index performance over the term of the Notes. The Index Factor negatively impacts the Interest Rate over time, which can result in lower interest payments later in the term of the Notes. The Index may not be successful. It may not outperform an alternative strategy related to the Basket Constituents. Changes in the value of Basket Constituents may offset each other. The Index is subject to emerging markets risk, fixed income risks, currency exchange risk, real estate risk, small capitalization stock risk and the uncertain legal and regulatory regimes which govern commodities future contracts. Upon the occurrence of a commodity hedging disruption event, the amount of your coupon payments may be reduced. Our affiliate, JPMSL, is the index calculation agent and may adjust the Index in a way that affects its level. No interest payments, dividend payments or voting rights with respect to assets underlying the Index. The tax consequences of the Notes may be uncertain. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the Notes. Certain built in costs are likely to adversely affect the value of the Notes prior to maturity. The original issue price of theNotes includes the agent's commission and the estimated cost of hedging our obligations under the Notes. As a result, the price, if any, at which JPMS 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. Lack of liquidity: JPMorgan Securities LLC, acting as agent for the Issuer (and who we refer to as JPMS), intends to offer topurchase the Notes in the secondary market but is not required to do so. The price, if any, at which JPMS will be willing to purchase Notes from you in the secondary market, if at all, may result in a significant loss of your principal. Many economic and market factors, such as Index volatility, time to maturity, interest rates and creditworthiness of the Issuer, will impact the value of the Notes prior to maturity. Potential conflicts: we and our affiliates play a variety of roles in connection with the issuance of Notes, including acting as note calculation agent and index calculation agent, and hedging our obligations under the Notes. It is possible that such hedging or other trading activities of JPMorgan or its affiliates could result in substantial returns for JPMorgan and its affiliates while the value of the Notes decline.
