Key Terms

Index:	The EURO STOXX 50® Index (the “Index”)
Knock-Out Buffer Amount:	28.00%
Payment at Maturity:	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.  Accordingly, if the Ending Index Level is greater than the Initial Index Level, your payment at maturity per $1,000 principal amount note will be calculated as follows:
	$1,000 + ($1,000 × Index Return)

	If the Ending Index Level is less than the Initial Index Level and a Knock-Out Event has occurred, 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, and your payment at maturity per $1,000 principal amount note will be calculated as follows:
	$1,000 + ($1,000 × Index Return)
	If the Ending Index Level is less than the Initial Index Level by more than the Knock-Out Buffer Amount, a Knock-Out Event has occurred, and the benefit provided by the Knock-Out Buffer Amount will terminate.  Under these circumstances, you will lose more than 28.00% of your initial investment and may lose all of your initial investment at maturity.

What Is the Total Return on the Notes at Maturity, Assuming a Range of Performances for the Index?

The following table illustrates the hypothetical total return at maturity on the notes. The “total return” as used in this pricing supplement is the number, expressed as a percentage, that results from comparing the payment at maturity per $1,000 principal amount note to $1,000. Each hypothetical total return set forth below assumes an Initial Index Level of 2,700 and reflects the Knock-Out Buffer Amount of 28.00%. Each hypothetical total return set forth below is for illustrative purposes only and may not be the actual total return applicable to a purchaser of the notes. The numbers appearing in the following table and examples have been rounded for ease of analysis.

		Total Return if Knock- Out Event Has Not Occurred (1)	Total Return if Knock-Out Event Has Occurred (2)
Ending Index Level	Index Return
4,860.00	80.00%	80.00%	N/A

270.00	-90.00%	N/A	-90.00%
0.00	-100.00%	N/A	-100.00%

(1) The Ending Index Level is greater than or equal to 1,944.00 (72.00% of the hypothetical Initial Index Level).

(2) The Ending Index Level is less than 1,944.00 (72.00% of the hypothetical Initial Index Level).

Hypothetical Examples of Amounts Payable at Maturity

The following examples illustrate how the total returns set forth in the table above are calculated.

Example 1: The level of the Index increases from the Initial Index Level of 2,700 to an Ending Index Level of 2,835 — a Knock-Out Event has not occurred. Because the Ending Index Level of 2,835 is greater than the Initial Index Level of 2,700 and the Index Return is 5.00%, the investor receives a payment at maturity of $1,050 per $1,000 principal amount note, calculated as follows:

$1,000 + ($1,000 × 5%) = $1,050

Example 2: The level of the Index decreases from the Initial Index Level of 2,700 to an Ending Index Level of 1,944— a Knock-Out Event has not occurred. Although the Ending Index Level of 1,944 is less than the Initial Index Level of 2,700, because a Knock-Out Event has not occurred, the investor receives a payment at maturity of $1,000 per $1,000 principal amount note.

Example 3: The level of the Index decreases from the Initial Index Level of 2,700 to an Ending Index Level of 1,620 — a Knock-Out Event has occurred. Because the Ending Index Level of 1,620 is less than the Initial Index Level of 2,700 by more than the Knock-Out Buffer Amount of 28.00%, a Knock-Out Event has occurred and the investor receives a payment at maturity of $400 per $1,000 principal amount note, calculated as follows:

$1,000 + ($1,000 × -60%) = $400

The hypothetical returns and hypothetical payments on the notes shown above do not reflect fees or expenses that would be associated with any sale in the secondary market. If these fees and expenses were included, the hypothetical returns and hypothetical payments shown above would likely be lower.

Selected Purchase Considerations

· UNLEVERAGED AND UNCAPPED APPRECIATION POTENTIAL — The notes provide the opportunity to earn an unleveraged return equal to any positive Index Return. The notes are not subject to a predetermined maximum gain and, accordingly, any return at maturity will be determined based on the movement of the Index. Because the notes are our unsecured and unsubordinated obligations, payment of any amount on the notes is subject to our ability to pay our obligations as they become due.

· LIMITED PROTECTION AGAINST LOSS — We will pay you your principal back at maturity if the Ending Index Level is not less than the Initial Index Level by more than the Knock-Out Buffer Amount (i.e., if a Knock-Out Event has not occurred). If the Ending Index Level is less than the Initial Index Level by more than the Knock-Out Buffer Amount (i.e., if a Knock-Out Event has occurred), the benefit provided by the Knock-Out Buffer will terminate, and for every 1% that the Ending Index Level is less than the Initial Index Level by more than the Knock-Out Buffer Amount, you will lose an amount equal to 1% of the principal amount of your notes. See “What Is the Total Return on the Notes at Maturity, Assuming a Range of Performances for the Index?” on PS-2 of this pricing supplement.

· RETURN LINKED TO THE EURO STOXX 50^® INDEX — The EURO STOXX 50^® Index consists of 50 component stocks of market sector leaders from within the Eurozone. The EURO STOXX 50^® Index and STOXX^® are the intellectual property (including registered trademarks) of STOXX Limited, Zurich, Switzerland and/or its licensors (the “Licensors”), which are used under license. The notes based on the EURO STOXX 50^® Index are in no way sponsored, endorsed, sold or promoted by STOXX Limited and its Licensors and neither of the Licensors shall have any liability with respect thereto. For additional information about the Index, see the information set forth under “Equity Index Descriptions — The EURO STOXX 50^® Index” in the accompanying underlying supplement no. 1-I.

· CAPITAL GAINS TAX TREATMENT — You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 4-I. The following discussion, when read in combination with that section, constitutes the full opinion of our special tax counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of notes.

Based on current market conditions, in the opinion of our special tax counsel it is reasonable to treat the notes as “open transactions” that are not debt instruments for U.S. federal income tax purposes. Assuming this treatment 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 treatment of the notes, in which case the timing and character of any income or loss on the notes could be materially 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. The notice focuses in particular on whether to require investors in 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. investors 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 a notional 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. You should consult your tax adviser 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.

Selected Risk Considerations

An investment in the notes involves significant risks. Investing in the notes is not equivalent to investing directly in the Index or any of the component securities of the Index. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement no. 4-I dated November 14, 2011 and “Risk Factors” in the accompanying underlying supplement no. 1-I dated November 14, 2011.

· 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 Index and will depend on whether a Knock-Out Event has occurred and whether, and the extent to which, the Index Return is positive or negative. If the Ending Index Level is less than the Initial Index Level by more than the Knock-Out Buffer Amount, a Knock-Out Event has occurred, and the benefit provided by the Knock-Out Buffer Amount will terminate. Under these circumstances, you will at maturity be fully exposed to any depreciation in the Index. If a Knock-Out Event has occurred, for every 1% that the Ending Index Level is less than the Initial Index Level, you will lose an amount equal to 1% of the principal amount of your notes. Accordingly, you will lose more than 28.00% of your initial investment and may lose all of your initial investment at maturity.

· 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, 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 adversely affect the value of the notes.  If we were to default on our payment obligations, you may not receive any amounts owed to you under the notes and you could lose your entire investment.

· 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, our economic interests and the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the notes. In addition, our business activities, including hedging and trading activities, could cause our economic interests to be adverse to yours and could adversely affect any payment on the notes and the

JPMorgan Structured Investments —	PS-3
Single Observation Knock-Out Buffered Equity Notes Linked to the EURO STOXX 50® Index

value of the notes. It is possible that hedging or trading activities of ours or our affiliates could result in substantial returns for us or our affiliates while the value of the notes declines. Please refer to “Risk Factors — Risks Relating to the Notes Generally” in the accompanying product supplement no. 4-I for additional information about these risks.

· THE BENEFIT PROVIDED BY THE KNOCK-OUT BUFFER AMOUNT MAY TERMINATE ON THE OBSERVATION DATE — If the Ending Index Level is less than the Initial Index Level by more than the Knock-Out Buffer Amount of 28.00%, the benefit provided by the Knock-Out Buffer Amount will terminate and you will be fully exposed to any depreciation in the Index. Because the Ending Index Level will be determined based on the Index closing level on a single day near the end of the term of the notes, the Index closing level at the maturity date or at other times during the term of the notes could be less than the Ending Index Level by not more than the Knock-Out Buffer Amount, or could be equal to or greater than the Initial Index Level. This difference could be particularly large if there is a significant decrease in the level of the Index during the later portion of the term of the notes or if there is significant volatility in the level of the Index 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 any payment on the notes 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, and as a general matter, 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. This secondary market price will also be affected by a number of factors aside from the agent’s commission and hedging costs, including those set forth under “Many Economic and Market Factors Will Impact the Value of the Notes” below.

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 INTEREST OR DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the notes, you will not receive interest payments, and you will not have voting rights or rights to receive cash dividends or other distributions or other rights that holders of securities composing the Index would have.

· RISK OF A KNOCK-OUT EVENT OCCURRING IS GREATER IF THE INDEX IS VOLATILE — The likelihood that the Ending Index Level will be less than the Initial Index Level by more than the Knock-Out Buffer Amount of 28.00%, thereby triggering a Knock-Out Event, will depend in large part on the volatility of the Index — the frequency and magnitude of changes in the level of the Index.

· NON-U.S. SECURITIES RISK — The equity securities that compose the Index 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, governmental intervention in those markets and cross shareholdings in companies in certain countries. Also, there is generally less publicly available information about companies in some of these jurisdictions than about U.S. companies that are subject to the reporting requirements of the SEC, and generally non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements and securities trading rules different from those applicable to U.S. reporting companies. The prices of securities in foreign markets may be affected by political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws. Moreover, the economies in such countries may differ favorably or unfavorably from the economy in the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

· NO DIRECT EXPOSURE TO FLUCTUATIONS IN FOREIGN EXCHANGE RATES — The value of your notes will not be adjusted for exchange rate fluctuations between the U.S. dollar and the currencies upon which the equity securities underlying the Index are based, although any currency fluctuations could affect the performance of the Index. Therefore, if the applicable currencies appreciate or depreciate relative to the U.S. dollar over the term of the notes, you will not receive any additional payment or incur any reduction in your payment at maturity.

· 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.

· MANY ECONOMIC AND MARKET FACTORS WILL IMPACT THE VALUE OF THE NOTES— In addition to the level of the Index on any day, the value of the notes will be impacted by a number of economic and market factors that may either offset or magnify each other, including:

· the actual and expected volatility of the Index;

· the time to maturity of the notes;

· whether a Knock-Out Event is expected to occur;

· the dividend rates on the equity securities underlying the Index;

· interest and yield rates in the market generally;

· the exchange rate and the volatility of the exchange rate between the U.S. dollar and the European Union euro;

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

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