North America Structured Investments 13 month Return Notes linked to JPMorgan US Long Equity Dynamic Overlay Index Overview The J.P. Morgan US Long Equity Dynamic Overlay 80 Index (Series 1) (the "Index" or "LEDO") is a rules -based Index designed to provide a synthetic long position in the total return version of the S&P 500 [R] Index (the "Equity Index") and limited downside protection against adverse movements of the Equity Index through a synthetic collar strategy as an overlay to the synthetic long position in the total return version of the Equity Index, subject to fees and deductions. The Index consists of three positions: a synthetic long position in the S&P 500 [R] Total Return Index, a synthetic rolling collar strategy applied to the "price return" version of the Equity Index (the "Price Return Equity Index"), and a synthetic delta hedge position with respect to the synthetic short call position consisting of a variable synthetic exposure to futures contracts referencing the Price Return Equity Index. The notes are designed for investors who seek exposure to the J. P. Morgan U. S. Long Equity Dynamic Overlay 80 Index (Series 1), subject to the fees and deductions described below. Investors should be willing to forgo interest payments and, if, between the Pricing Date and the Observation Date, the level of the Index (which reflects the deductions described below) decreases or does not increase sufficiently to offset the fees and deductions described below, be willing to lose some or all of their principal.

While we intend to accept all requests for early repurchase of notes, we are not obligated to accept any repurchase request. We are not committed to purchasing any note at a particular time or price. ** The hypothetical returns and hypothetical payments on the notes shown above apply only at maturity. These hypotheticals do not reflect fees or expenses that would be associated with any sale in the secondary market.

You may also request that we repurchase your notes prior to maturity.* The notes provide the opportunity to obtain an uncapped return at maturity or upon early repurchase linked to the Index. Your payment at maturity, or upon early repurchase, is subject to the credit risk of JPMorgan Chase & Co. The level of the Index incorporates the daily deduction of (a) the index fee of 0.75% per annum (the "Only Index Fee"), (b ) the Call deduction and put deduction: on a monthly or quarterly basis, as applicable, when the Index's synthetic short call or long put exposure, as applicable, is rolled into a new option contract on the S&P 500[R] Index, a call deduction or put deduction, as applicable, is subtracted in the calculation of the Index. The call deduction or put deduction is calculated by multiplying a) the applicable volatility spread (which is between 0.30% and 3.00%) by b) the vega of the applicable option contract, subject to certain minimum and maximum amounts and (c) when the delta hedge implemented, 0.03% of any increase or decrease in the Index's exposure to the futures contracts on the Price Return Equity Index is deducted in the calculation of the Index. JPMS's estimated value reflects the Daily Index Fee that will accrue on a daily basis over the term of the notes. The call deduction and put deduction do not impact JPMS's estimated value. The level of the Index and the value of the notes will be adversely affected, perhaps significantly, if the performance of the S&P 500[R] Total Return Index (the "Total Return Equity Index") and the option contracts and futures contracts on the Price Return Equity Index included in the Index, in aggregate, is not sufficient to offset these fees and deductions.

[] The averaging convention used to calculate the ending index level could limit returns. [] Daily repurchases in minimum denominations equal to the principal amount. While we intend to accept all requests for early repurchase of notes, we are not obligated to accept any repurchase request. We are not committed to purchasing any note at a particular time or price. [] Potential for Long Term Capital Gains tax treatment if held longer than one year. Selected Risks [] The risks identified below are not exhaustive. Please see "Risk Factors" in the applicable product supplement and any applicable underlying supplement and "Selected Risk Considerations" to the applicable term sheet for additional information. [] Your investment in the notes may result in a loss. The return on your initial investment will reflect the daily deduction of the index fee and the daily rebalancing adjustment amount from the level of the Index and, in the case of an early repurchase, the deduction of the repurchase fee. If the Index declines by 100% from its initial level at maturity, you would lose all of your principal. There are no interest payment on the notes. [] Payment on the notes 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. [] You may receive less than your initial investment due to the index fee, call and put deduction, and delta hedge deduction . These fees and deductions are likely to have a substantial adverse effect on the level of the Index over time. Selected Risks (continued) [] Our affiliate, J.P.

[] The Index provides exposure to equity options and futures, which are subject to significant fluctuations, and are not suitable for all investors. [] There are risks associated with the delta hedging. [] There are risks associated with synthetic options. [] The Index references a synthetic portfolio of underlying assets. [] The Index may not be successful and may not outperform any alternative strategy. [] The cost of synthetically trading the options and futures constituents may negatively impact performance. [] Even with delta hedging, the Index may still underperform the underlying equity Index. [] Even though the Index maintains a long put position, the level of the Index may not increase when the market decreases. [] The Index is an excess return index, thought it tracks a total return index. [] JPMS's estimated value does not represent future values and may differ from others' estimates. [] The notes' value in customer account statements may be higher than JPMS's current estimated value for a limited time period.
