Morgan Structured Investments | 800 576 3529 | JPM_Structured_Investments@jpmorgan.com OVERVIEW May be appropriate for investors anticipating moderate appreciation in the Index during the term of the note and those seeking to enhance returns through leverage within the specified range of performance in exchange for a maximum return. Downside market out performance relative to the Index is achieved by virtue of the Buffer. The payment at maturity references the Index directly and is not subject to any tracking error at maturity.

Return Profile If the ending Index level is greater than its initial level, you will receive a cash payment that provides you with a return per $1,000 principal amount note equal to the Index return multiplied by the Upside Leverage Factor, subject to the Maximum Total Return on the notes. If the Ending Index Level is equal to or less than the Initial Index Level by up to the buffer amount, you will receive the principal amount of your notes at maturity. If the Index declines from its initial level by greater than the Buffer Amount, you will lose 1% of the principal amount of your notes for every 1% that the Index has declined beyond the buffer. * To be determined on the Pricing Date, but not less than 14% ** Reflects a Maximum Total Return of 14% for illustrative purposes and assumes a $1,000 investment 1

[] Potential for Long Term Capital Gains tax treatment if held longer than one year. Selected Risks [] Your investment in the notes may result in a loss. [] Payment on the notes at maturity 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.

[] JPMS' estimated value does not represent future values and may differ from others' estimates. [] The value of the notes which may be reflected in customer account statements may be higher than JPMS' current estimated value for a limited time period. [] Lack of liquidity: JPMorgan Securities, LLC, acting as agent for the Issuer (and who we refer to as JPMS), intends to offer to purchase 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. [] Potential conflicts: we and our affiliates play a variety of roles in connection with the issuance of notes, including acting as calculation agent and hedging our obligations under the notes, and making the assumptions used to determine the pricing of the notes and the estimated value of the notes when the terms of the notes are set. 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.
