2year Contingent Coupon Autocallable Yield Notes [GRAPHIC OMITTED] ================================================================================ North America Structured Investments OVERVIEW May be appropriate for investors seeking contingent interest payments during the term of the notes. If any underlying is less than its Trigger Level on March 26, 2015 investors have full downside exposure to the least performing of the underlyings. Under these circumstances the payment at maturity will be made in cash based on the least performing Underlying. If on any Review Date, the closing level of each underlying is greater than its closing level on the Pricing Date, the Notes will be automatically called. The payment at maturity will be made in cash based on the return of the lesser performing of the Underlyings. Any payment on the notes is subject to the credit risk of JPMorgan Chase & Co.

2year Contingent Coupon Autocallable Yield Notes [GRAPHIC OMITTED] ================================================================================ North America Structured Investments Selected Benefits [] The notes offer a higher interest rate than the yield currently available on debt securities of comparable maturity issued by us. [] Quarterly contingent interest payments. [] Minimum denomination of $1,000 and integral multiples thereof. Selected Risks [] Your investment in the notes may result in a loss. The Notes do not guarantee any return of principal. [] The notes do not guarantee the payment of interest and may not pay interest at all. [] If the Notes have not been called and a Trigger Event has occurred, you will lose 1% of your principal amount at maturity for every 1% that the Final Level of the Least Performing Underlying is less than its Initial Level. [] Any payment on the notes is subject to our credit risk. Therefore the value of the notes prior to maturity are subject to changes in the market's view of our creditworthiness. [] You are exposed to the risks of the decline in the value of each Underlying. [] Your payment at maturity may be determined by the least performing of the Underlyings. [] Return is limited to the principal amount plus accrued interest regardless of any appreciation of the Underlyings, which may be significant. You will not participate in any appreciation in the value of any Underlying. []The automatic call feature may force a potential early exit. There is no guarantee you will be able to reinvest the proceeds at a comparable interest rate for a similar level of risk if the notes are redeemed early. [] The benefit provided by the Trigger Level may terminate on the final Review Date. [] No dividend payments, ownership rights or affiliation with the Underlyings. [] You are exposed to the risks associated with small capitalization companies. [] The notes are subject to currency exchange risk. [] The equity securities underlying the Fund have been issued by non-U.S. companies. Investments in securities linked to the value of such non-U.S. equity securities involve risks associated with the securities markets in those countries, including risks of volatility in those markets, government intervention in those markets and cross shareholdings in companies in certain countries. []The Anti-dilution protection for the Fund is limited, and there may be differences between the Fund and its underlying index. [] Certain built-in costs are likely to adversely affect the value of the Notes prior to maturity. The original issue price of the notes includes the agent's commission and the estimated cost of hedging our obligations under the notes. As a result, the price, if any, at which JPMS will be willing to purchase notes from you in secondary market transactions, if at all, will likely be lower than the original issue price and any sale prior to the maturity date could result in a substantial loss to you. [] 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. [] Many economic and market factors, such as volatility of the Underlyings, time to maturity, the Contingent Interest Rate, interest rates generally and creditworthiness of the Issuer, will impact the value of the notes prior to maturity. [] 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. 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. [] The tax consequences of the notes may be uncertain. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the notes. The risks identified above are not exhaustive. Please see "Risk Factors" in the applicable product supplement and "Selected Risk Considerations" to the applicable term sheet for additional information. --------------------------------------------------------------------------------------------------------- Disclaimer SEC Legend: JPMorgan Chase & Co. has filed a registration statement (including a prospectus) with the SEC for any offering to which these materials relate.
