Rule 424(b)(8)

The notes are designed for investors who seek to participate in the appreciation of the closing price of one share of the Reference Stock, up to the Maximum Return of 20.00% at maturity, and who anticipate that the closing price of one share of the Reference Stock on the Observation Date (i.e., the Final Share Price) will not be less than the Initial Share Price by more than 30.00%. Investors should be willing to forgo interest and dividend payments and, if the Final Share Price is less than the Initial Share Price by more than 30.00%, be willing to lose some or all of their principal. If the Final Share Price is not less than the Initial Share Price by more than 30.00%, investors have the opportunity to receive the greater of (a) the Share Return and (b) the Contingent Minimum Return of 17.65% at maturity, subject to the Maximum Return of 20.00%. Any payment on the notes is subject to the credit risk of JPMorgan Chase & Co.

Senior unsecured obligations of JPMorgan Chase & Co. maturing November 28, 2012^†

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

The notes priced on November 11, 2011 and are expected to settle on or about November 16, 2011.

If a Knock-Out Event has occurred, you will receive a cash payment at maturity that will reflect the performance of the Reference Stock, subject to the Maximum Return. Under these circumstances, your payment at maturity per $1,000 principal amount note will be calculated as follows:

$1,000 + ($1,000 × Share Return), subject to the Maximum Return

If a Knock-Out Event has occurred, you will lose more than 30.00% of your initial investment and may lose all of your initial investment at maturity.

If a Knock-Out Event has not occurred, you will receive a cash payment at maturity that will reflect the performance of the Reference Stock, subject to the Contingent Minimum Return and the Maximum Return. If a Knock-Out Event has not occurred, your payment at maturity per $1,000 principal amount note will equal $1,000 plus the product of (a) $1,000 and (b) the greater of (i) the Contingent Minimum Return and (ii) the Share Return, subject to the Maximum Return. For additional clarification, please see “What Is the Total Return on the Notes at Maturity, Assuming a Range of Performances for the Reference Stock?” in this pricing supplement.

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 17.65% on the notes, for a minimum payment at maturity of $1,176.50 for every $1,000 principal amount note, subject to the Maximum Return of 20.00%. The maximum payment at maturity is $1,200 per $1,000 principal amount note. 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 Dow Chemical. For additional information see “The Reference Stock” in this 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 on the Observation Date (i.e., the Final Share Price) is less than the Initial Share Price by more than the Knock-Out Buffer Amount of 30.00%, a Knock-Out Event has occurred, and the benefit provided by the Knock-Out Buffer Amount of 30.00% will terminate. If a Knock-Out Event has occurred, for every 1% that the Final Share Price is less than the Initial Share Price, you will lose an amount equal to 1% of the principal amount of your notes. Under these circumstances, you will lose more than 30.00% of your initial investment and may lose all of your initial investment at maturity.

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.

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.

THE BENEFIT PROVIDED BY THE KNOCK-OUT BUFFER MAY TERMINATE ON THE OBSERVATION DATE — If the closing price of one share of the Reference Stock on the Observation Date (i.e., the Final Share Price) is less than the Initial Share Price by more than the Knock-Out Buffer Amount of 30.00%, the benefit provided by the Knock-Out Buffer Amount will terminate and you will be fully exposed to any depreciation in the closing price of one share of the Reference Stock. Because the Final Share Price will be determined based on the closing price on a single day near the end of the term of the notes, the price of the Reference Stock at the maturity date or at other times during the term of the notes could be at a level above the Initial Share Price minus the Knock-Out Buffer Amount. This difference could be particularly large if there is a significant decrease in the price of the Reference Stock during the later portion of the term of the notes or if there is significant volatility in the price of the Reference Stock during the term of the notes, especially on dates near the Observation Date.

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 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 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 on the Observation Date (i.e., the Final Share Price) will be less than the Initial Share Price by more than the Knock-Out Buffer Amount of 30.00%, 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.

PS-4        

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.

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. It is possible that such hedging or trading activities could result in substantial returns for us or our affiliates while the value of the notes declines.

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

the time to maturity of the notes;

whether a Knock-Out Event is expected to occur;

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.
