Senior Fixed Rate Step-Up Callable Notes due October 28, 2026

The Notes

The notes offered are senior unsecured obligations of JPMorgan Chase & Co. We describe the basic features of these notes in the sections of the accompanying prospectus called “Description of Debt Securities,” the accompanying prospectus supplement called “Description of Notes” and the accompanying product supplement no. MS-8-A-I called “Description of Notes,” subject to and as modified by the provisions described above. All payments on the notes are subject to the credit risk of JPMorgan Chase & Co.

Risk Factors

The following is a non-exhaustive list of certain key risk factors for investors in the notes. For further discussion of these and other risks, you should read the section entitled “Risk Factors” beginning on page PS-4 of the accompanying product supplement no. MS-8-A-I. We also urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the notes.

§ Early redemption risk. The issuer retains the option to redeem the notes on any semi-annual redemption date, beginning on October 28, 2012. It is more likely that the issuer will redeem the notes prior to their stated maturity date to the extent that the interest payable on the notes is greater than the interest that would be payable on other instruments of the issuer of a comparable maturity, terms and credit rating trading in the market. If the notes are redeemed prior to their stated maturity date, you may have to re-invest the proceeds in a lower rate environment. 
§ These notes may be riskier than notes with a shorter term. By purchasing a note with a longer term, you are more exposed to fluctuations in interest rates than if you purchased a note with a shorter term. Specifically, you may be negatively affected if certain interest rate scenarios occur. Generally, if the prevailing interest rate begins to rise, the market value of your notes may decline because the yield to maturity on the notes may be less than the interest rate on a note issued at such time. For example, if the yield to maturity on the notes at such time was 4.00% per annum, but a debt security issued in the then current market could yield an interest rate of 6.25% per annum, your note may be less valuable if you tried to sell your note in the secondary market. 
§ The notes are subject to the credit risk of JPMorgan Chase & Co., and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the notes. Investors are dependent on JPMorgan Chase & Co.’s ability to pay all amounts due on the notes at maturity, and therefore investors are subject to our credit risk and to changes in the market’s view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the value of the notes. 
§ Economic interests of the calculation agent and other affiliates of the issuer may be different from those of investors. We and our affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and hedging our obligations under the securities. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the securities. 
§ The market price of the notes is influenced by many unpredictable factors. Several factors will influence the value of the notes in the secondary market and the price at which JPMS may be willing to purchase or sell the notes in the secondary market, including: (i) changes in (and volatility of) U.S. interest rates, (ii) the likelihood, or expectation, that the notes will be redeemed by us prior to maturity (iii) any actual or anticipated changes in our credit ratings or credit spreads, (iv) a variety of economic, financial, regulatory and judicial events and (v) time remaining to maturity. 
§ The inclusion in the original issue price of commissions and estimated cost of hedging is likely to affect adversely secondary market prices. Assuming no change in market conditions or any other relevant factors, the price, if any, at which JPMS is willing to purchase the notes in secondary market transactions will likely be lower than the original issue price, because the original issue price will include, and secondary market prices are likely to exclude, commissions paid with respect to the notes, as well as the estimated cost of hedging the issuer’s obligations under the notes. In addition, any such prices may differ from values determined by pricing models used by JPMS, as a result of dealer discounts, mark-ups or other transaction costs. The notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your notes to maturity.

§ Secondary trading may be limited. The notes will not be listed on a securities exchange. There may be little or no secondary market for the notes. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. JPMS may act as a market maker for the notes, but is not required to do so. Because we do not expect that other market makers will participate significantly in the secondary market for the notes, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which JPMS is willing to buy the notes. If at any time JPMS or another agent does not act as a market maker, it is likely that there would be little or no secondary market for the notes
§ JPMS and its affiliates may have published research, expressed opinions or provided recommendations that are inconsistent with investing in or holding the notes. Any such research, opinions, or recommendations could affect the market value of the notes. JPMS and its affiliates publish research from time to time on movements in interest rates, the financial markets and other matters that may influence the value of the notes, or express opinions or provide recommendations that are inconsistent with purchasing or holding the notes. JPMS and its affiliates may have published research or other opinions that call into question the investment view implicit in an investment in the notes. Any research, opinions or recommendations expressed by JPMS or its affiliates may not be consistent with each other and may be modified from time to time without notice. Investors should make their own independent investigation of the merits of investing in the notes.

Supplemental Plan of Distribution

Subject to regulatory constraints, JPMS intends to use its reasonable efforts to offer to purchase the notes in the secondary market, but is not required to do so.

 

We or our affiliate may enter into swap agreements or related hedge transactions with one of our other affiliates or unaffiliated counterparties in connection with the sale of the notes and JPMS and/or an affiliate may earn additional income as a result of payments pursuant to the swap or related hedge transactions. See “Use of Proceeds” beginning on page PS-7 of the accompanying product supplement no. MS-8-A-I.
