Capped Buffered Return Enhanced Notes Linked to the S&P GSCI™ Excess Return due September 23, 2013

General

· The notes are designed for investors who seek a return of 1.5 times the appreciation of the S&P GSCI™ Excess Return, up to a maximum return of 11.00% at maturity. Investors should be willing to forgo interest payments and, if the Ending Index Level is less than the Index Strike Level by more than 10%, be willing to lose up to 90% of their principal. Any payment on the notes is subject to the credit risk of JPMorgan Chase & Co.

· Unsecured and unsubordinated obligations of JPMorgan Chase & Co. maturing September 23, 2013*

· Minimum denominations of $1,000 and integral multiples thereof

· The notes priced on September 11, 2012 and are expected to settle on or about September 14, 2012.

· The notes are not commodity futures contracts and are not regulated under the Commodity Exchange Act of 1936, as amended (the “Commodity Exchange Act”). The notes are offered pursuant to an exemption from regulation under the Commodity Exchange Act, commonly known as the hybrid instrument exemption, that is available to securities that have one or more payments indexed to the value, level or rate of one or more commodities, as set out in section 2(f) of that statute. Accordingly, you are not afforded any protection provided by the Commodity Exchange Act or any regulation promulgated by the Commodity Futures Trading Commission.

Key Terms

Index:	The S&P GSCI™ Excess Return (the “Index”). The official weekday closing level of the S&P GSCI™ Excess Return is published each trading day under the Bloomberg ticker symbol “SPGCCIP.” For more information on the Index, please see “Selected Purchase Considerations — Return Linked to the S&P GSCITM Excess Return” in this pricing supplement.
Upside Leverage Factor:	1.5
Payment at Maturity:	If the Ending Index Level is greater than the Index Strike 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 multiplied by 1.5, subject to the Maximum Return. Accordingly, if the Ending Index Level is greater than the Index Strike Level, your payment at maturity per $1,000 principal amount note will be calculated as follows:
	$1,000 + ($1,000 × Index Return × 1.5), subject to the Maximum Return
	If the Ending Index Level is equal to the Index Strike Level or is less than the Index Strike Level by up to 10%, you will receive the principal amount of your notes at maturity. If the Ending Index Level is less than the Index Strike Level by more than 10%, you will lose 1% of the principal amount of your notes for every 1% that the Ending Index Level is less than the Index Strike Level by more than 10%, and your payment at maturity per $1,000 principal amount note will be calculated as follows:
	$1,000 + [$1,000 × (Index Return + 10%)]
	If the Ending Index Level is less than the Index Strike Level by more than 10%, you could lose up to $900 per $1,000 principal amount note.
Maximum Return:	11.00%. For example, if the Index Return is equal to or greater than 7.33%, you will receive the Maximum Return, which entitles you to a maximum payment at maturity of $1,110 per $1,000 principal amount note that you hold.
Buffer Percentage:	10%
Index Return:	Ending Index Level – Index Strike Level Index Strike Level
Index Strike Level:	501.8351, which is the closing level of the Index on the pricing date.
Ending Index Level:	The Index Closing Level on the Observation Date
Observation Date*:	September 18, 2013
Maturity Date*:	September 23, 2013
CUSIP:	48125V6K1

Capped Buffered Return Enhanced Notes Linked to the S&P GSCI™ Excess Return

Selected Purchase Considerations

· CAPPED APPRECIATION POTENTIAL — The notes provide the opportunity to enhance returns by multiplying a positive Index Return by 1.5, up to the Maximum Return of 11.00%, for a maximum payment at maturity of $1,110 per $1,000 principal amount note. 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 Index Strike Level by more than 10%. If the Ending Index Level is less than the Index Strike Level by more than 10%, for every 1% that the Ending Index Level is less than the Index Strike Level by more than 10%, you will lose an amount equal to 1% of the principal amount of your notes. Accordingly, you could lose up to $900 for each $1,000 principal amount note that you invest in.

· RETURN LINKED TO THE S&P GSCI&™ Excess Return — The return on the notes is linked to the S&P GSCI™ Excess Return, the excess return version of the S&P GSCI™, a composite index of commodity sector returns, calculated, maintained and published daily by Standard & Poor’s Financial Services LLC. The S&P GSCI™ is a world production-weighted index that is designed to reflect the relative significance of principal non-financial commodities (i.e., physical commodities) in the world economy. The S&P GSCI™ represents the return of a portfolio of the futures contracts for the underlying commodities. The S&P GSCI™ Excess Return is an excess return index and not a total return index. An excess return index reflects the returns that are potentially available through an investment in the contracts composing the index. By contrast, a “total return” index, in addition to reflecting those returns, also reflects interest that could be earned on funds committed to the trading of the underlying futures contracts. See “The S&P GSCI Indices” in the accompanying product supplement no. 2-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. 2-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 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, which might include 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.

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 in any futures contracts or exchange-traded or over-the-counter instruments based on, or other instruments linked to, the Index. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement no. 2-I dated November 14, 2011.

· YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS — The notes do not guarantee any return of principal at maturity in excess of $100 per $1,000 principal amount note, subject to the credit risk of JPMorgan Chase & Co. The return on the notes at maturity is linked to the performance of the Index and will depend on whether, and the extent to which, the Index Return is positive or negative. If the Ending Index Level is less than the Index Strike Level by more than 10%, you will lose 1% of the principal amount of your notes for every 1% that the Ending Index Level is less than the Index Strike Level by more than 10%. Accordingly, you could lose up to $900 for each $1,000 principal amount note that you invest in.

· YOUR MAXIMUM GAIN ON THE NOTES IS LIMITED BY THE MAXIMUM RETURN — If the Ending Index Level is greater than the Index Strike Level, 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 11.00%, regardless of the appreciation in the Index, 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, 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.

Recent events affecting us have led to heightened regulatory scrutiny, may lead to additional regulatory or legal proceedings against us and may adversely affect our credit ratings and credit spreads and, as a result, the market value of the notes. See “Executive Overview — Recent Developments,” “Liquidity Risk Management — Credit Ratings,” “Item 4. Controls and Procedures” and “Part II. Other Information — Item 1A. Risk Factors” in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2012.

· POTENTIAL CONFLICTS — We and our affiliates play a variety of roles in connection with the issuance of the notes, including acting as Note Calculation Agent and hedging our obligations under the notes. In performing these duties, our economic interests and the economic interests of the Note 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 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” in the accompanying product supplement no. 2-I for additional information about these risks.

· 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.

· PRICES OF COMMODITY FUTURES CONTRACTS ARE CHARACTERIZED BY HIGH AND UNPREDICTABLE VOLATILITY, WHICH COULD LEAD TO HIGH AND UNPREDICTABLE VOLATILITY IN THE INDEX — Market prices of the commodity futures contracts included in the Index tend to be highly volatile and may fluctuate rapidly based on numerous factors, including the factors that affect the price of the commodities underlying the commodity futures contracts included in the Index. See “The Market Prices of the Commodities Underlying the Futures Contracts Included in the Index Will Affect the Value of the Notes” below. The prices of commodity futures contracts are subject to variables that may be less significant to the values of traditional securities, such as stocks and bonds. These variables may create additional investment risks that cause the value of the notes to be more volatile than the values of traditional securities. As a general matter, the risk of low liquidity or volatile pricing around the maturity date of a commodity futures contract is greater than in the case of other futures contracts because (among other factors) a number of market participants take physical delivery of the underlying commodities. Many commodities are also highly cyclical. The high volatility and cyclical nature of commodity markets may render such an investment inappropriate as the focus of an investment portfolio.

· WE MAY ACCELERATE YOUR NOTES IF A COMMODITY HEDGING DISRUPTION EVENT OCCURS — If we or our affiliates are unable to effect transactions necessary to hedge our obligations under the notes due to a commodity hedging disruption event, we may, in our sole and absolute discretion, accelerate the payment on your notes and pay you an amount determined in good faith and in a commercially reasonable manner by the Note Calculation Agent. If the payment on your

JPMorgan Structured Investments —	PS-3
Capped Buffered Return Enhanced Notes Linked to the S&P GSCI™ Excess Return

notes is accelerated, your investment may result in a loss and you may not be able to reinvest your money in a comparable investment. Please see “General Terms of Notes — Consequences of a Commodity Hedging Disruption Event — Early Acceleration of Payment on the Notes” in the accompanying product supplement no. 2-I for more information.

· COMMODITY FUTURES CONTRACTS ARE SUBJECT TO UNCERTAIN LEGAL AND REGULATORY REGIMES — The commodity futures contracts that underlie the Index are subject to legal and regulatory regimes in the United States and, in some cases, in other countries that may change in ways that could adversely affect our ability to hedge our obligations under the notes and affect the level of the Index. Any future regulatory changes, including but not limited to changes resulting from the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), which was enacted on July 21, 2010, may have a substantial adverse effect on the value of your notes. Additionally, in accordance with the Dodd-Frank Act, the U.S. Commodity Futures Trading Commission has adopted regulations that establish position limits for certain commodity-based futures contracts, such as futures contracts on certain energy, agricultural and metals based commodities. These regulations may reduce liquidity in the exchange-traded market for those commodity-based futures contracts. Furthermore, we or our affiliates may be unable as a result of those restrictions to effect transactions necessary to hedge our obligations under the notes, in which case we may, in our sole and absolute discretion, accelerate the payment on your notes. See “We May Accelerate Your Notes If a Commodity Hedging Disruption Event Occurs” above.

· THE MARKET PRICES OF THE COMMODITIES UNDERLYING THE FUTURES CONTRACTS INCLUDED IN THE INDEX WILL AFFECT THE VALUE OF THE NOTES — The prices of the commodities upon which the futures contracts that compose the Index are based are affected by numerous factors, including: changes in supply and demand relationships, governmental programs and policies, national and international monetary, trade, political and economic events, wars and acts of terror, changes in interest and exchange rates, speculation and trading activities in commodities and related contracts, general weather conditions, and agricultural, trade, fiscal and exchange control policies. Many commodities are also highly cyclical. These factors, some of which are specific to the market for each such commodity, may cause the value of the different commodities upon which the futures contracts that compose the Index are based, as well as the futures contracts themselves, to move in inconsistent directions at inconsistent rates. This, in turn, will affect the value of the notes linked to the Index. It is not possible to predict the aggregate effect of all or any combination of these factors.

· A DECISION BY AN EXCHANGE ON WHICH THE FUTURES CONTRACTS UNDERLYING THE INDEX ARE TRADED TO INCREASE MARGIN REQUIREMENTS MAY AFFECT THE LEVEL OF THE INDEX — If an exchange on which the futures contract underlying the Index are traded increases the amount of collateral required to be posted to hold positions in those futures contracts (i.e., the margin requirements), market participants who are unwilling or unable to post additional collateral may liquidate their positions, which may cause the level of the Index to decline significantly.

· THE NOTES DO NOT OFFER DIRECT EXPOSURE TO COMMODITY SPOT PRICES — The notes are linked to the Index, which tracks commodity futures contracts, not physical commodities (or their spot prices). The price of a futures contract reflects the expected value of the commodity upon delivery in the future, whereas the spot price of a commodity reflects the immediate delivery value of the commodity. A variety of factors can lead to a disparity between the expected future price of a commodity and the spot price at a given point in time, such as the cost of storing the commodity for the term of the futures contract, interest charges incurred to finance the purchase of the commodity and expectations concerning supply and demand for the commodity. The price movements of a futures contract are typically correlated with the movements of the spot price of the referenced commodity, but the correlation is generally imperfect and price movements in the spot market may not be reflected in the futures market (and vice versa). Accordingly, the notes may underperform a similar investment that is linked to commodity spot prices.

· OWNING THE NOTES IS NOT THE SAME AS OWNING ANY COMMODITIES OR COMMODITY FUTURES CONTRACTS — The return on your notes will not reflect the return you would realize if you actually purchased the futures contracts composing the Index, the commodities upon which the futures contracts that compose the Index are based, or other exchange-traded or over-the-counter instruments based on the Index. You will not have any rights that holders of those assets or instruments have.

· HIGHER FUTURES PRICES OF THE COMMODITY FUTURES CONTRACTS UNDERLYING THE INDEX RELATIVE TO THE CURRENT PRICES OF THOSE CONTRACTS MAY AFFECT THE LEVEL OF THE INDEX AND THE VALUE OF THE NOTES — The Index is composed of futures contracts on physical commodities. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, commodity futures contracts normally specify a certain date for delivery of the underlying physical commodity. As the exchange-traded futures contracts that compose the Index approach expiration, they are replaced by contracts that have a later expiration. Thus, for example, a contract purchased and held in August may specify an October expiration. As time passes, the contract expiring in October is replaced with a contract for delivery in November. This process is referred to as “rolling.” If the market for these contracts is (putting aside other considerations) in “contango,” where the prices are higher in the distant delivery months than in the nearer delivery months, the purchase of the November contract would take place at a price that is higher than the price of the October contract, thereby creating a negative “roll yield.” Contango could adversely affect the level of the Index and thus the value of notes linked to the Index. The futures contracts underlying the Index have historically been in contango.

· SUSPENSION OR DISRUPTIONS OF MARKET TRADING IN THE COMMODITY MARKETS AND RELATED FUTURES MARKETS MAY ADVERSELY AFFECT THE LEVEL OF THE INDEX, AND THEREFORE THE LEVEL OF THE NOTES — The commodity markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention. In addition, U.S. futures exchanges and some

JPMorgan Structured Investments —	PS-4
Capped Buffered Return Enhanced Notes Linked to the S&P GSCI™ Excess Return

foreign exchanges have regulations that limit the amount of fluctuation in futures contract prices that may occur during a single day. These limits are generally referred to as “daily price fluctuation limits” and the maximum or minimum price of a contract on any given day as a result of these limits is referred to as a “limit price.” Once the limit price has been reached in a particular contract, no trades may be made at a different price. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices. These circumstances could adversely affect the level of the Index and, therefore, the value of your notes.

· The notes are linked to an excess return index and not a total return index — The notes are linked to an excess return index and not a total return index. An excess return index, such as the Index, reflects the returns that are potentially available through an unleveraged investment in the contracts composing that index. By contrast, a “total return” index, in addition to reflecting those returns, also reflects interest that could be earned on funds committed to the trading of the underlying futures contracts.

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

· 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 and the underlying futures contracts;

· the time to maturity of the notes;

· the market price of the physical commodities upon which the futures contracts underlying the Index are based;

· interest and yield rates in the market generally;

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

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

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

The following table and examples illustrate 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 500 and reflects the Maximum Return of 11.00% and the Buffer Percentage of 10%. 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.

Ending Index Level	Index Return	Total Return
900.00	80.00%	11.00%
825.00	65.00%	11.00%
750.00	50.00%	11.00%
700.00	40.00%	11.00%
650.00	30.00%	11.00%
600.00	20.00%	11.00%
575.00	15.00%	11.00%
550.00	10.00%	11.00%
535.00	7.33%	11.00%
525.00	5.00%	7.50%
505.00	1.00%	1.50%
500.00	0.00%	0.00%
475.00	-5.00%	0.00%
450.00	-10.00%	0.00%
425.00	-15.00%	-5.00%
400.00	-20.00%	-10.00%

0.00	-100.00%	-90.00%

Hypothetical Examples of Amounts Payable at Maturity

The following examples illustrate how the payment at maturity in different hypothetical scenarios is calculated.

Example 1: The level of the Index increases from the Index Strike Level of 500 to an Ending Index Level of 525. Because the Ending Index Level of 525 is greater than the Index Strike Level of 500 and the Index Return of 5% multiplied by 1.5 does not exceed the Maximum Return of 11.00%, the investor receives a payment at maturity of $1,075 per $1,000 principal amount note, calculated as follows:

$1,000 + ($1,000 × 5% × 1.5) = $1,075

Example 2: The level of the Index decreases from the Index Strike Level of 500 to an Ending Index Level of 450. Although the Index Return is negative, because the Ending Index Level of 450 is less than the Index Strike Level of 500 by not more than the Buffer Percentage of 10%, the investor receives a payment at maturity of $1,000 per $1,000 principal amount note.

Example 3: The level of the Index increases from the Index Strike Level of 500 to an Ending Index Level of 650. Because the Ending Index Level of 650 is greater than the Index Strike Level of 500 and the Index Return of 30% multiplied by 1.5 exceeds the Maximum Return of 11.00%, the investor receives a payment at maturity of $1,110 per $1,000 principal amount note, the maximum payment on the notes.

Example 4: The level of the Index decreases from the Index Strike Level of 500 to an Ending Index Level of 350. Because the Index Return is negative and the Ending Index Level of 350 is less than the Index Strike Level of 500 by more than the Buffer Percentage of 10%, the investor receives a payment at maturity of $800 per $1,000 principal amount note, calculated as follows:

$1,000 + [$1,000 × (-30% + 10%)] = $800

Example 5: The level of the Index decreases from the Index Strike Level of 500 to an Ending Index Level of 0. Because the Index Return is negative and the Ending Index Level of 0 is less than the Index Strike Level of 500 by more than the Buffer Percentage of 10%, the investor receives a payment at maturity of $100 per $1,000 principal amount note, which reflects the benefit provided by the Buffer Percentage of 10%, calculated as follows:

$1,000 + [$1,000 × (-100% + 10%)] = $100

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 total returns and payments shown above would likely be lower.
