J.P. Morgan Strategic Volatility Dynamic Index OVERVIEW The J.P. Morgan Strategic Volatility Dynamic Index (the "Index") aims to provide exposure to volatility by combining a long position and a contingent short position in futures contracts on the CBOE Volatility Index([R]) (the "VIX") futures curve. The index maintains a systematic long position in 3(rd), 4(th), 5(th) and 6(th) month futures contracts and progressively activates a short position in 2(nd) and 3(rd) month VIX futures contracts if the VIX Index was less than the rolling weighted average of the 2(nd) and 3(rd) month futures contracts for each of the 3 preceding Index Business Days (i.e. when the market is in contango). Under these circumstances, the short position is weighted such that the Index retains a net flat-to-long volatility position. The index is therefore designed to "carry flat" in normal market conditions while providing enhanced protection in the event of spikes in volatility. You may lose some or all of your principal at maturity. Any payment on the notes is subject to the credit risk of J.P. Morgan Chase & Co. Brief Background on Volatility Investing [] The VIX Index, published by the Chicago Board of Options Exchange ("CBOE"), is viewed as the benchmark index for measuring the market's expectation of the near-term (30 days) volatility of the S&P 500[R] Index. [] Volatility, as measured by the VIX Index, has historically increased during periods of decline in the equity markets. (See the chart below.) However, the VIX Index is not an investable index. [] Futures contracts on the VIX Index were introduced by the CBOE in 2004 to provide investable access to volatility. [] The VIX futures curve is often in "contango"(1) which can, all else being equal, result in negative returns for a strategy that is long VIX futures.

Morgan. As of 3/31/2015. PAST PERFORMANCE AND BACK-TESTED PERFOMANCE ARE NOT INDICATIVE OF FUTURE RESULTS. The J.P. Morgan Strategic Volatility Dynamic Index was launched on 8/31/2012, and therefore any data used for that index prior to that date is back-tested and does not represent actual historical data. The hypothetical back-tested performance of the Index is calculated on materially the same basis as the performance of the Index is now calculated, but does not represent the actual historical performance of the Index and has not been verified by an independent third party. Alternative modeling techniques or assumptions may produce different hypothetical historical information that might prove to be more appropriate and that might differ significantly from the hypothetical historical information of the Index. In addition, back-tested, hypothetical historical results 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. How the Index Works [] Maintains long exposure to the 4-month point VIX futures curve. [] A contingent short position at the 2-month point on the VIX future curve is activated during certain market scenarios (as described below) and beta adjusted in an attempt to maintain a net flat to long volatility exposure. [] When activated, the short position is increased in daily increments with a maximum daily change in exposure of 25%; when de-activated it is decreased in 25% daily decrements. The short position ranges from 0% to 100%. [] The synthetic long position in the futures contracts measures the return from rolling a synthetic position from the third-month into the sixth-month VIX futures contract (while maintaining positions in the four-month and fifth-month VIX futures contracts). [] The synthetic short exposure to the futures contracts, when activated, measures the return from rolling a synthetic short position from the second-month to the third-month VIX futures contract. [] Volatile Markets: Relative move of the short leg vs. long leg increases, weight on short leg decreases [] Normal Markets: Relative move of the short leg vs long leg decreases weight on short leg increases. [] Activation Signal: On any day if the level of the VIX Index is below the rolling weighted average of the second and third-month futures for each of the 3 preceding Index Business Days (as would typically be the case when the curve is in contango). [] Deactivation Signal: On any day that the level of the VIX Index is at or above the rolling weighted average of the second and third-month VIX futures for each of the 3 preceding Index Business Days the short position is de-activated (in 25% decrements). [] The level of the Index incorporates the daily deduction of (a) the index fee of 0.75% per annum and (b) a "daily rebalancing adjustment amount" that is determined by applying a rebalancing adjustment factor of between 0.20% and 0.50% per day, both to the aggregate notional amount of each of the VIX futures contracts hypothetically traded that day and the amount of the change, if any, in the level of the exposure to the synthetic short position. Please review the relevant product supplement we have filed and any relevant term sheet or pricing supplement for further details on the J.P. Morgan Strategic Volatility Dynamic Index, including the daily rebalancing adjustment amount. J.P.

Hypothetical historical illustration of the exposure to the short component of the Strategic Volatility Dynamic Index: September 2008 to March 2015 [GRAPHIC OMITTED] Source: J.P. Morgan. As of 3/31/2015. PAST PERFORMANCE AND BACK-TESTED PERFORMANCE ARE NOT INDICATIVE OF FUTURE LEVELS. The Strategic Volatility Dynamic Index was launched on 8/30/2012; therefore any data used for that Index prior to that date is back-tested. The hypothetical, exposure to the short leg obtained from such back-testing should not be considered indicative of the actual exposure that would be realized during an investment in the Index. The information in this chart is provided solely for reference. Index fee and deductions for rebalancing adjustments [] The reported level of the Index incorporates the daily deduction of (a) an index fee of 0.75% per annum and (b) a "daily rebalancing adjustment amount" that is determined by applying a rebalancing adjustment factor of between 0.20% and 0.50% per day, both to the aggregate notional amount of each of the VIX futures contracts hypothetically traded that day and the amount of the change, if any, in the level of the exposure to the synthetic short position. [] The daily rebalancing adjustment amount is intended to approximate the "slippage costs" that would be experienced by a professional investor seeking to replicate the hypothetical portfolio contemplated by the Index at prices that approximate the official settlement prices (which are not generally tradable) of the relevant VIX futures contracts. Glossary of Select Terms "contango" is used to describe the shape of a futures curve when the price of a futures contract with a later expiration is higher than that of a futures contract with an earlier expiration. "backwardation" is the opposite of contango and is used to describe the shape of a futures curve when the price of a futures contract with a later expiration is lower than the price of a futures contract with an earlier expiration. "negative roll yield" / "positive roll yield": Because futures contracts have specific expiration dates, in order for an investor to maintain exposure, the investor needs to sell a futures contracts as it gets close to expiration and purchase another contract with a later expiration date. This process is known as "rolling" the futures position. When a futures curve is in "contango" (see above), all else being equal, an investor in a long futures position pays a higher price to buy a later expiration futures contract than the price at which the investor sells the contract as it nears expiration, thus suffering negative returns ("negative roll yield"). Whereas when the futures curve is in "backwardation" (see above), all else being equal, an investor in a long futures position pays a lower price to buy a later expiring futures contract than the price at which the investor sells the contract as it nears expiration thus generating positive returns ("positive roll yield"). What are the main risks in the Index? [] Any securities we may issue linked to the Index may result in a loss, and are exposed to the credit risk of J.P. Morgan Chase & Co. [] The Index has limited operating history. [] The reported level of the Index incorporates the daily deduction of (a) an index fee of 0.75% per annum and (b) a "daily rebalancing adjustment amount" (as described above). [] The daily rebalancing adjustment amount is likely to have a substantial adverse effect on the level of the Index. [] The Index may not be successful and may not outperform any alternative strategy. [] Strategies that provide exposure to equity volatility, which are subject to significant fluctuations, are not suitable for all investors. [] When the synthetic short position is activated, your return on the notes is dependent on the net performance, not the absolute performance, of the long and short positions. [] Due to the time lag inherent in the Index, the exposure to the synthetic short position may not be adjusted quickly enough to offset loss or generate profit. [] The Index comprises only notional assets and liabilities. [] The Index is an excess return index and reflects the performance of an uncollateralized investment in futures contracts. [] The level of the Index may not increase even when the synthetic long position and the synthetic short positions, when activated, generates a positive return. [] Because there is no limit to possible increases in the value of VIX futures contracts underlying the synthetic short position, when activated, the potential drag of this short exposure on the closing level of the Index is unlimited. In no event, however, will you lose more than your entire investment linked to the performance of the Index. [] Our affiliate, J.P.
