Term Sheet to

Product Supplement No. 206-A-I

Registration Statement No. 333-155535

Dated November 1, 2011; Rule 433

The notes are designed for investors who seek a return of at least three times the appreciation above the Call Price of the Contract Price of the first nearby month (or, in some circumstances, the second nearby month) futures contract on Brent crude oil, stated in U.S. dollars per barrel, as made public by ICE Futures Europe, up to a maximum total return on the notes of at least 60.00% at maturity, or early exit prior to maturity at a premium if, on any one of the three Review Dates, the Contract Price is at or above the Call Price applicable to that Review Date. If the notes are not automatically called, investors will lose some or all of their principal if the Ending Contract Price is less than the Initial Contract Price by more than 10%. Investors in the notes should be willing to accept this risk of loss and be willing to forgo interest payments, in exchange for the opportunity to receive a premium payment if the notes are automatically called or a capped, leveraged upside payment if the notes are not automatically called. Any payment on the notes is subject to the credit risk of JPMorgan Chase & Co.

The notes are linked to the Contract Price of the Commodity Futures Contract, as described below. See “Selected Purchase Considerations — Return Linked Solely to the Contract Price of Brent Crude Oil Futures Contracts” and “Selected Risk Considerations — The Notes Do Not Offer Direct Exposure to Commodity Spot Prices” in this term sheet for more information.

The first Review Date, and therefore the earliest date on which a call may be initiated, is February 6, 2012.

The notes are not 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 that is available to securities that have one or more payments indexed to the value, level or rate of one or more commodities, which is 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.

Senior unsecured obligations of JPMorgan Chase & Co. maturing November 15, 2012^†

Minimum denominations of $20,000 and integral multiples of $1,000 in excess thereof

The notes are expected to price on or about November 4, 2011 and are expected to settle on or about November 9, 2011.

•     at least 4.00* × $1,000 if called on the first Review Date

•     at least 8.00%* × $1,000 if called on the second Review Date

•     at least 12.00%* × $1,000 if called on the final Review Date

If the notes have not been automatically called and the Ending Contract Price is greater than or equal to the Initial Contract Price or less than the Initial Contract Price by up to 5%, you will receive at maturity a cash payment that provides you with a return per $1,000 principal amount note equal to the Contract Return plus 5%, multiplied by the Upside Leverage Factor, subject to a Maximum Return on the notes of at least 60.00%**. For example, assuming the Maximum Return is 60.00%** and the Upside Leverage Factor is 3, if the Contract Return is equal to or greater than 15%, you will receive the Maximum Return on the notes of 60.00%**, which entitles you to a maximum payment at maturity of $1,600** for every $1,000 principal amount note that you hold. Accordingly, if the Ending Contract Price is greater than or equal to the Initial Contract Price or less than the Initial Contract Price by up to 5%, your payment at maturity per $1,000 principal amount note will be calculated as follows, subject to the Maximum Return:

$1,000 + [$1,000 × (Contract Return + 5%) × Upside Leverage Factor]

** The actual Maximum Return on the notes and the actual maximum payment at maturity will be set on the pricing date and will not be less than 60.00% and $1,600 per $1,000 principal amount note, respectively.

If the Ending Contract Price is less than the Initial Contract Price by more than 5% but is not less than the Initial Contract Price by more than 10%, you will receive the principal amount of your notes at maturity.

If the Ending Contract Price is less than the Initial Contract Price by more than 10%, you will lose 1.1111% of the principal amount of your notes for every 1% that the Ending Contract Price is less than the Initial Contract Price by more than 10%. Under these circumstances, your payment at maturity per $1,000 principal amount note will be calculated as follows:

$1,000 + [$1,000 × (Contract Return + 10%) × 1.1111]

If the notes have not been automatically called, you will lose some or all of your initial investment at maturity if the Ending Contract Price is less than the Initial Contract Price by more than 10%.

Subject to postponement in the event of a market disruption event and as described under “Description of Notes — Payment at Maturity” and “Description of Notes — Postponement of a Determination Date — A. Notes linked to a single Commodity or a single Commodity Futures Contract” in the accompanying product supplement no. 206-A-I or early acceleration in the event of a commodity hedging disruption event as described under “General Terms of Notes — Consequences of a Commodity Hedging Disruption Event — C. Early Acceleration of Payment on the Notes” in the accompanying product supplement no. 206-A-I and in “Selected Risk Considerations — We May Accelerate Your Notes If a Commodity Hedging Disruption Event Occurs” in this term sheet.

POTENTIAL EARLY EXIT WITH APPRECIATION AS A RESULT OF AUTOMATIC CALL FEATURE — While the original term of the notes is just over one year, the notes will be called before maturity if the Contract Price is at or above the relevant Call Price on the applicable Review Date and you will be entitled to the applicable payment corresponding to such Review Date set forth on the cover of this term sheet.

LIMITED PROTECTION AGAINST LOSS — If the notes have not been automatically called, we will pay you your principal back at maturity if the Ending Contract Level is not less than the Initial Contract Price by more than 10.00%. If the Ending Contract Price is less than the Initial Contract Price by more than 10.00%, for every 1% that the Ending Contract Price is less than the Initial Contract Price by more than 10.00%, you will lose an amount equal to 1.1111% of the principal amount of your notes. Under these circumstances, you will lose some or all of your initial investment at maturity. For additional clarification, please see “Hypothetical Examples of Amounts Payable upon Automatic Call or at Maturity” in this term sheet.

RETURN LINKED SOLELY TO THE CONTRACT PRICE OF BRENT CRUDE OIL FUTURES CONTRACTS — The return on the notes is linked solely to the official settlement price on ICE Futures Europe of the first nearby month (or, in some circumstances, the second nearby month) futures contract for Brent crude oil, stated in U.S. dollars per barrel, as made public by ICE Futures Europe. The Contract Return reflects the performance of the Commodity Futures Contract, expressed as a percentage, from the Initial Contract Price to the Contract Price on the final Review Date. For additional information about the Commodity Futures Contract, see the information set forth under “Description of Notes — Payment at Maturity” and “The Commodity Futures Contracts” in the accompanying product supplement no. 206-A-I.

CAPITAL GAINS TAX TREATMENT — You should review carefully the section entitled “Certain U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 206-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, as described in the section entitled “Certain U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders — Notes Treated as Open Transactions” in the accompanying product supplement. Assuming this characterization is respected, the gain or loss on your notes should be treated as short-term capital gain or loss unless you hold your notes for more than a year, in which case the gain or loss should be long-term capital gain or loss, 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, 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. 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 at maturity. If the notes have not been automatically called, the return on the notes at maturity is linked to the performance of the Commodity Futures Contract and will depend on whether, and the extent to which, the Contract Price is positive or negative. Your investment will be exposed to loss on a leveraged basis if the notes have not been automatically called and the Ending Contract Price is less than the Initial Contract Price by more than the Buffer Percentage of 10.00%. For every 1% that the Ending Contract Price is less than the Initial Contract Price by more than 10.00%, you will lose an amount equal to 1.1111% of the principal amount of your notes. Under these circumstances, you will lose some or 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 at maturity or upon an automatic call, 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. It is possible that such hedging or other trading activities of ours or our affiliates could result in substantial returns for us or our affiliates while the value of the notes declines.

CERTAIN BUILT-IN COSTS ARE LIKELY TO AFFECT ADVERSELY THE VALUE OF THE NOTES PRIOR TO MATURITY — While the payment at maturity or upon an automatic call described in this term sheet 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 J.P. Morgan Securities LLC, which we refer to as 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 the notes to maturity.

IF THE NOTES ARE CALLED EARLY, YOUR RETURN IS LIMITED TO THE CALL PREMIUM — If the notes are automatically called, your potential gain on the notes will be limited to the call premium, as set forth on the cover of this term sheet, regardless of the appreciation in the Contract Price, which may be significant. Because the Contract Price at various times during the term of the notes could be higher than on a Review Date or at maturity, you may receive a lower payment if called or at maturity, as the case may be, than you would have if you had invested directly in the Commodity Futures Contract.

IF THE NOTES ARE NOT CALLED EARLY, YOUR RETURN IS LIMITED TO THE MAXIMUM RETURN — In addition, if the notes have not been automatically called and the Ending Contract Price is greater than or equal to the Initial Contract Price or is less than the Initial Contract Price by up to 5%, for each $1,000 principal amount note, you will receive at maturity $1,000 plus an additional return that will not exceed a predetermined percentage of the principal amount, regardless of the appreciation in the Contract Price, which may be significant. We refer to this predetermined percentage as the Maximum Return, which will be set on the pricing date and will not be less than 60.00%.

REINVESTMENT RISK — If your notes are automatically called, the term of the notes may be reduced to as short as three months. There is no guarantee that you would be able to reinvest the proceeds from an investment in the notes at a comparable return for a similar level of risk in the event the notes are automatically called prior to the maturity date.

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 calculation agent. If the payment on your 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 — C. Early Acceleration of Payment on the Notes” in the accompanying product supplement no. 206-A-I for more information.

COMMODITY FUTURES CONTRACTS ARE SUBJECT TO UNCERTAIN LEGAL AND REGULATORY REGIMES — Commodity futures contracts 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 value of the Commodity Futures Contract. 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 is drafting regulations that will affect market participants’ position limits in certain commodity-based futures contracts, such as futures contracts on certain agricultural commodities, energy commodities and metals. These proposed regulations, when final and implemented, may reduce liquidity in the exchange-traded market for such commodity-based futures contracts. Furthermore, we or our affiliates may be unable as a result of such 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.

PRICES OF COMMODITY FUTURES CONTRACTS ARE CHARACTERIZED BY HIGH AND UNPREDICTABLE VOLATILITY — Market prices of commodity futures contracts tend to be highly volatile and may fluctuate rapidly based on numerous factors, including the factors that affect the price of the commodity underlying the Commodity Futures Contract. See “The Market Price of Brent Crude Oil Will Affect the Value of the Notes” below. The Contract Price of the Commodity Futures Contract is subject to variables that may be less significant to the values of traditional securities, such as stocks and bonds. These additional 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.

THE MARKET PRICE OF BRENT CRUDE OIL WILL AFFECT THE VALUE OF THE NOTES — Because the notes are linked to the performance of the Contract Price of the Commodity Futures Contract, we expect that generally the market value of the notes will depend in part on the market price of Brent crude oil. The price of IPE brent blend crude oil futures is primarily affected by the global demand for and supply of crude oil, but is also influenced significantly from time to time by speculative actions and by currency exchange rates. Crude oil prices are generally more volatile and subject to dislocation than prices of other commodities. Demand for refined petroleum products by consumers, as well as the agricultural, manufacturing and transportation industries, affects the price of crude oil. Crude oil’s end-use as a refined product is often as transport fuel, industrial fuel and in-home heating fuel. Potential for substitution in most areas exists, although considerations including relative cost often limit substitution levels. Because the precursors of demand for petroleum products are linked to economic activity, demand will tend to reflect economic conditions. Demand is also influenced by government regulations, such as environmental or consumption policies. In addition to general economic activity and demand, prices for crude oil are affected by political events, labor activity and, in particular, direct government intervention (such as embargos) or supply disruptions in major oil producing regions of the world. Such events tend to affect oil prices worldwide, regardless of the location of the event. Supply for crude oil may increase or decrease depending on many factors. These include production decisions by the Organization of the Petroleum Exporting Countries (“OPEC”) and other crude oil producers. Crude oil prices are determined with significant influence by OPEC. OPEC has the potential to influence oil prices worldwide because its members possess a significant portion of the world’s oil supply. In the event of sudden disruptions in the supplies of oil, such as those caused by war, natural events, accidents or acts of terrorism, prices of oil futures contracts could become extremely volatile and unpredictable. Also, sudden and dramatic changes in the futures market may occur, for example, upon a cessation of hostilities that may exist in countries producing oil, the introduction of new or previously withheld supplies into the market or the introduction of substitute products or commodities. Crude oil prices may also be affected by short-term changes in supply and demand because of trading activities in the oil market and seasonality (e.g., weather conditions such as hurricanes). It is not possible to predict the aggregate effect of all or any combination of these factors.

FUTURES CONTRACTS ON BRENT CRUDE OIL ARE THE BENCHMARK CRUDE OIL CONTRACTS IN EUROPEAN AND ASIAN MARKETS — Because futures contracts on Brent crude oil are the benchmark crude oil contracts in European and Asian markets, the Commodity Futures Contract will be affected by economic conditions in Europe and Asia. A decline in economic activity in Europe or Asia could result in decreased demand for crude oil and for futures contracts on crude oil, which could adversely affect the value of the Commodity Futures Contract and, therefore, the notes.

THE CONTRACT PRICE OF THE COMMODITY FUTURES CONTRACT IS DETERMINED BY REFERENCE TO THE OFFICIAL SETTLEMENT PRICE OF BRENT CRUDE OIL FUTURES CONTRACTS AS DETERMINED BY ICE FUTURES EUROPE, AND THERE ARE CERTAIN RISKS RELATING TO THE CONTRACT PRICE OF THE COMMODITY FUTURES CONTRACT BEING DETERMINED BY ICE FUTURES EUROPE — Futures contracts on Brent crude oil are traded on ICE Futures Europe. The Contract Price of the Commodity Futures Contract will be determined by reference to the official settlement price on ICE Futures Europe of the Commodity Futures Contract, stated in U.S. dollars per barrel, as made public by ICE Futures Europe. Investments in securities linked to the value of commodity futures contracts that are traded on non-U.S. exchanges, such as ICE Futures Europe, involve risks associated with the markets in those countries, including risks of volatility in those markets and governmental intervention in those markets.

A DECISION BY ICE FUTURES EUROPE TO INCREASE MARGIN REQUIREMENTS FOR BRENT CRUDE FUTURES CONTRACTS MAY AFFECT THE CONTRACT PRICE OF THE COMMODITY FUTURES CONTRACT — If ICE Futures Europe increases the amount of collateral required to be posted to hold positions in the futures contracts on Brent crude oil (i.e. the margin requirements), market participants who are unwilling or unable to post additional collateral may liquidate their positions, which may cause the Contract Price of the Commodity Futures Contract to decline significantly.

THE NOTES DO NOT OFFER DIRECT EXPOSURE TO COMMODITY SPOT PRICES — The notes are linked to the Commodity Futures Contract, which reflects the price of a futures contract, not a physical commodity (or its spot price). 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.

SINGLE COMMODITY FUTURES CONTRACT PRICES TEND TO BE MORE VOLATILE THAN, AND MAY NOT CORRELATE WITH, THE PRICES OF COMMODITIES GENERALLY — The notes are linked exclusively to the Commodity Futures Contract and not to a diverse basket of commodities or commodity futures contracts or a broad-based commodity index. The Contract Price of the Commodity Futures Contract may not correlate to the price of commodities or commodity futures contracts generally and may diverge significantly from the prices of commodities or commodity futures contracts generally. Because the notes are linked to the price of

JPMorgan Structured Investments —

Autocallable Buffered Return Enhanced Notes Linked to a Brent Crude Oil Futures Contract

TS-6        

a single commodity futures contract, they carry greater risk and may be more volatile than notes linked to the prices of multiple commodities or commodity futures contracts or a broad-based commodity index.

OWNING THE NOTES IS NOT THE SAME AS OWNING THE COMMODITY FUTURES CONTRACT — The return on your notes will not reflect the return you would realize if you actually purchased the Commodity Futures Contract or other exchange-traded or over-the-counter instruments based on the Commodity Futures Contract. You will not have any rights that holders of such assets or instruments have.

SUSPENSION OR DISRUPTIONS OF MARKET TRADING IN THE COMMODITY MARKETS AND RELATED FUTURES MARKETS MAY ADVERSELY AFFECT THE PRICE OF THE COMMODITY FUTURES CONTRACT, AND THEREFORE THE VALUE 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 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 price of the Commodity Futures Contract and, therefore, the value of your notes.

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 AFFECT THE VALUE OF THE NOTES — In addition to the price of the Commodity Futures Contract 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 volatility, frequency and magnitude of changes in the Contract Price of the Commodity Futures Contract;

supply and demand trends for Brent crude oil and the Commodity Futures Contract;

the time to maturity of the notes;

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.
