Source: J.P. Morgan. Past performance is not a guide to future performance. "EEJPDS5E Index" refers to the performance of J.P. Morgan ETF Efficiente DS 5 Index (Bloomberg: EEJPDS5E Index)(the "Index"). The levels of the Index incorporate an adjustment factor of 1.0% per annum. Hypothetical, historical performance measures: Represents the monthly and full calendar year performance of the Index based on as applicable to the relevant measurement period, the hypothetical back tested daily closing levels from December 31, 2003 through September 24, 2012, and the actual historical performance of the Index based on daily closing levels from September 25, 2012 through June 30, 2014. YTD reflects the year to date performance of the Index from the last business day of the previous calendar year through, and including June 28, 2013. The hypothetical historical values above have not been verified by an independent third party. The back-tested, hypothetical historical results above have inherent limitations. These back-tested results are achieved by means of a retroactive application of a back-tested model designed with the benefit of hindsight. No representation is made that an investment linked to the Index will or is likely to achieve returns similar to those shown. Alternative modelling techniques or assumptions would produce different hypothetical historical information that might prove to be more appropriate and that might differ significantly from the hypothetical historical information set forth above. Hypothetical back-tested results are neither an indicator nor a guarantee of future returns. Actual results will vary, perhaps materially, from the analysis implied in the hypothetical historical information that forms part of the information contained in the table above. 1 D E T A I L S P E R F O R M A N C E I N D E X 5 D S E F F I C I E N T E E T F J P M O R G A N

Key Risks [] There are risks associated with a momentum-based investment strategy- The Index is different from a strategy that seeks long-term exposure to a portfolio consisting of constant components with fixed weights. The Index may fail to realize gains that could occur from holding assets that have experienced price declines, but experience a sudden price spike thereafter. [] The Index may not achieve its target volatility-- The exposure of the Index to the synthetic portfolio of Basket Constituents is determined by a two-step process composed of 1) a monthly selection process to determine the weighting assigned to each Basket Constituent in the synthetic portfolio, and 2) a daily adjustment of the exposure to the synthetic portfolio intended to achieve a target annualized volatility of 5% on a daily basis. The monthly weights and daily adjustments are based on the historical volatility of the synthetic portfolio and are subject to certain constraints. However, there is no guarantee that historical trends will continue in the future. Accordingly, the actual realized annualized volatility of the Index may be greater than or less than 5%, which may adversely affect the level of the Index. [] The daily adjustment of the exposure of the index to the synthetic portfolio of basket constituents may impact performance -- Due to the daily exposure adjustments, the Index may fail to realize gains due to price appreciation of the synthetic portfolio at a time when the exposure is less than 100% or may suffer increased losses due to price depreciation of the synthetic portfolio when the exposure is above 100%. As a result, the Index may underperform an index that does not include a daily exposure adjustment. [] The Index may be partially uninvested -- The aggregate weight of the Cash Index at any given time represents the portion of the synthetic portfolio that is uninvested. In addition, when the exposure of the Index to the synthetic portfolio is less than 100%, a portion of the synthetic portfolio will be uninvested. The Index will reflect no return for any uninvested portion. [] Our affiliate, J.P. Morgan Securities plc, is the calculation agent for the Index and may adjust the Index in a way that affects its level--The policies and judgments for which J.P. Morgan Securities plc, is responsible could have an impact, positive or negative, on the level of the Index and the value of your investment. J.P. Morgan Securities plc is under no obligation to consider your interest as an investor with returns linked to the Index. [] The Index may not be successful and may not outperform any alternative strategy. [] The Index comprises notional assets and liabilities and therefore there is no actual portfolio of assets to which any person is entitled or in which any person has any ownership interest. [] The Index rebalances monthly and applies weighting caps to the Basket Constituents and sectors. [] The Index may be subject to increased volatility due to the use of leverage. [] Changes in the value of the Basket Constituents may offset each other, and correlation of performances among the Basket Constituents may reduce the performance of the Index. [] An investment linked to the Index is subject to risks associated with non-U.S securities markets, such as emerging markets and currency exchange risk. [] The Index was established on September 25, 2012 and has a limited operating history. DISCLAIMER JPMorgan Chase & Co. ("J.P.
