CAPPED APPRECIATION POTENTIAL — The notes provide the opportunity to participate in the appreciation of the Reference Stock, up to the Maximum Return of 20.00% at maturity. If a Knock-Out Event has not occurred, in addition to the principal amount, you will receive at maturity at least the Contingent Minimum Return of 14.90% on the notes, or a minimum payment at maturity of $1,149 for every $1,000 principal amount note. Even if a Knock-Out Event has occurred, if the Final Share Price is greater than the Initial Share Price, in addition to the principal amount, you will receive at maturity a return on the notes equal to the Share Return, subject to the Maximum Return of 20.00%. The maximum payment at maturity is $1,200 per $1,000 principal amount note, regardless of whether a Knock-Out Event has occurred. Because the notes are our senior unsecured obligations, payment of any amount at maturity is subject to our ability to pay our obligations as they become due.

RETURN LINKED TO A SINGLE REFERENCE STOCK — The return on the notes is linked to the performance of a single Reference Stock, which is the common stock of Deere. For additional information see “The Reference Stock” in this amended and restated pricing supplement.

CAPITAL GAINS TAX TREATMENT — You should review carefully the section entitled “Certain U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 195-A-I. Subject to the limitations described therein, and based on certain factual representations received from us, in the opinion of our special tax counsel, Davis Polk & Wardwell LLP, it is reasonable to treat the notes as “open transactions” for U.S. federal income tax purposes. Assuming this characterization is respected, the gain or loss on your notes should be treated as long-term capital gain or loss if you hold your notes for more than a year, whether or not you are an initial purchaser of notes at the issue price. However, the Internal Revenue Service (the “IRS”) or a court may not respect this characterization or treatment of the notes, in which case the timing and character of any income or loss on the notes could be significantly and adversely affected. In addition, in 2007 Treasury and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments, such as the notes. The notice focuses in particular on whether to require holders of these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by Non-U.S. Holders should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose an interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the notes, possibly with retroactive effect. Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the notes, including possible alternative treatments and the issues presented by this notice. Non-U.S. Holders should also note that they may be withheld upon at a rate of up to 30% unless they have submitted a properly completed IRS Form W-8BEN or otherwise satisfied the applicable documentation requirements.

YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS — The notes do not guarantee any return of principal. The return on the notes at maturity is linked to the performance of the Reference Stock and will depend on whether a Knock-Out Event has occurred and whether, and the extent to which, the Share Return is positive or negative. If the closing price of one share of the Reference Stock is less than the Initial Share Price by more than the Knock-Out Buffer Amount of 25.00% on any day during the Monitoring Period, a Knock-Out Event has occurred, and the protection provided by the Knock-Out Buffer Amount of 25.00% will terminate. Under these circumstances, you could lose some or all of your principal.

YOUR MAXIMUM GAIN ON THE NOTES IS LIMITED TO THE MAXIMUM RETURN — If the Final Share Price is greater than the Initial Share Price, for each $1,000 principal amount note, you will receive at maturity $1,000 plus an additional return that will not exceed the Maximum Return of 20.00%, regardless of the appreciation in the Reference Stock, which may be significant.

PS-3        

CREDIT RISK OF JPMORGAN CHASE & CO. — The notes are subject to the credit risk of JPMorgan Chase & Co. and our credit ratings and 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 decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to affect adversely the value of the notes.

POTENTIAL CONFLICTS — We and our affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent and hedging our obligations under the notes. 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 notes.

YOUR PROTECTION MAY TERMINATE ON ANY DAY DURING THE MONITORING PERIOD — If the closing price of one share of the Reference Stock on any day during the Monitoring Period is less than the Initial Share Price by more than the Knock-Out Buffer Amount of 25.00%, you will at maturity be fully exposed to any depreciation in the Reference Stock. We refer to this feature as a contingent buffer. Under these circumstances, if the Final Share Price is less than the Initial Share Price, you will lose 1% of the principal amount of your investment for every 1% that the Final Share Price is less than the Initial Share Price. You will be subject to this potential loss of principal even if the Reference Stock subsequently increases such that the closing price of one share of the Reference Stock is less than the Initial Share Price by not more than the Knock-Out Buffer Amount of 25.00%, or is equal to or greater than the Initial Share Price. If these notes had a non-contingent buffer feature, under the same scenario, you would have received the full principal amount of your notes plus the Contingent Minimum Return at maturity. As a result, your investment in the notes may not perform as well as an investment in a security with a return that includes a non-contingent buffer.

YOUR ABILITY TO RECEIVE THE CONTINGENT MINIMUM RETURN OF 14.90% MAY TERMINATE ON ANY DAY DURING THE MONITORING PERIOD — If the closing price of one share of the Reference Stock on any day during the Monitoring Period is less than the Initial Share Price by more than the Knock-Out Buffer Amount of 25.00%, you will not be entitled to receive the Contingent Minimum Return of 14.90% on the notes. Under these circumstances, you may lose some or all of your investment at maturity and will be fully exposed to any depreciation in the Reference Stock.

CERTAIN BUILT-IN COSTS ARE LIKELY TO AFFECT ADVERSELY THE VALUE OF THE NOTES PRIOR TO MATURITY — While the payment at maturity described in this amended and restated pricing supplement is based on the full principal amount of your notes, 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. The notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your notes to maturity.

NO OWNERSHIP OR DIVIDEND RIGHTS IN THE REFERENCE STOCK — As a holder of the notes, you will not have any ownership interest or rights in the Reference Stock, such as voting rights or dividend payments. In addition, the issuer of the Reference Stock will not have any obligation to consider your interests as a holder of the notes in taking any corporate action that might affect the value of the Reference Stock and the notes.

NO AFFILIATION WITH THE REFERENCE STOCK ISSUER — We are not affiliated with the issuer of the Reference Stock. We assume no responsibility for the adequacy of the information about the Reference Stock issuer contained in this amended and restated pricing supplement. You should undertake your own investigation into the Reference Stock and its issuer. We are not responsible for the Reference Stock issuer’s public disclosure of information, whether contained in SEC filings or otherwise.

SINGLE STOCK RISK — The price of the Reference Stock can fall sharply due to factors specific to the Reference Stock and its issuer, such as stock price volatility, earnings, financial conditions, corporate, industry and regulatory developments, management changes and decisions and other events, as well as general market factors, such as general stock market volatility and levels, interest rates and economic and political conditions.

NO INTEREST PAYMENTS — As a holder of the notes, you will not receive any interest payments.

RISK OF KNOCK-OUT EVENT OCCURRING IS GREATER IF THE CLOSING PRICE OF THE REFERENCE STOCK IS VOLATILE — The likelihood that the closing price of one share of the Reference Stock will be less than the Initial Share Price by more than the Knock-Out Buffer Amount of 25.00% on any day during the Monitoring Period, thereby triggering a Knock-Out Event, will depend in large part on the volatility of the closing price of the Reference Stock — the frequency and magnitude of changes in the closing price of the Reference Stock.

LACK OF LIQUIDITY — The notes will not be listed on any securities exchange. JPMS intends to offer to purchase the notes in the secondary market but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. Because other dealers are not likely to make a 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.

PS-4        

HEDGING AND TRADING IN THE REFERENCE STOCK — While the notes are outstanding, we or any of our affiliates may carry out hedging activities related to the notes, including in the Reference Stock or instruments related to the Reference Stock. We or our affiliates may also trade in the Reference Stock or instruments related to the Reference Stock from time to time. Any of these hedging or trading activities as of the pricing date and during the term of the notes could adversely affect our payment to you at maturity.

THE ANTI-DILUTION PROTECTION FOR THE REFERENCE STOCK IS LIMITED — The calculation agent will make adjustments to the Stock Adjustment Factor for certain corporate events affecting the Reference Stock. However, the calculation agent will not make an adjustment in response to all events that could affect the Reference Stock. If an event occurs that does not require the calculation agent to make an adjustment, the value of the notes may be materially and adversely affected.

MANY ECONOMIC AND MARKET FACTORS WILL IMPACT THE VALUE OF THE NOTES — In addition to the closing price of one share of the Reference Stock on any day, the value of the notes will be affected by a number of economic and market factors that may either offset or magnify each other, including:

the expected volatility in the closing price of the Reference Stock;

the time to maturity of the notes;

whether a Knock-Out Event has occurred;

the dividend rate on the Reference Stock;

the occurrence of certain events affecting the issuer of the Reference Stock that may or may not require an adjustment to the Stock Adjustment Factor, including a merger or acquisition;

interest and yield rates in the market generally;

a variety of economic, financial, political, regulatory and judicial events; and

our creditworthiness, including actual or anticipated downgrades in our credit ratings.
