6yr DJUBS Contingent Buffered Notes OVERVIEW May be appropriate for investors who seek an uncapped exposure to the Dow Jones-UBS Commodity Index. Investors are exposed to the full downside of the Index if the Ending Index Level is less than the Initial Index Level by more than the Buffer Amount. The payment at maturity references the Index directly and is not subject to any tracking error at maturity. You may lose some or all of you principal at maturity. Any payment on the notes is subject to the credit risk of JPMorgan Chase and Co. Summary of Terms Issuer: JPMorgan Chase and Co. Minimum Denomination: $1,000 Index: Dow Jones-UBS Commodity Index Upside Leverage Factor: [1.0-1.1]* Contingent Buffer Amount: 35% Initial Index Level: The index closing level on the pricing date Ending Index Level: The index closing level on the Observation Date Pricing Date: July 19, 2013 Observation Date:: July 26, 2019 Maturity Date: July 31, 2019 CUSIP: 48126NHG5 Preliminary Term Sheet: http://www.sec.gov/Archives/edgar /data/19617/00008910921300585 3/e54388fwp.htm For information about the estimated value of the notes, which likely will be lower than the price you paid for the notes, see the hyperlink above. Return Profile If the Ending Index Level is greater than the Initial Index Level, at maturity 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. If the Ending Index Level is equal to or less than the Initial Index Level by up to the Contingent Buffer Amount, you will receive the principal amount of your notes at maturity. If the Ending Index Level is less than the Initial Index Level by more than the Contingent Buffer Amount, you will lose 1% of the principal amount of your notes for every 1% that the Ending Index Level is less than the Initial Index Level.

[] Minimum denominations of $10,000 and integral multiples of $1,000 in excess thereof [] 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.

[] 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. [] JPMS' estimated value is derived by reference to an internal funding rate. [] 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 asan agent of the offering of the notes 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.
