General

· The notes are designed for investors who seek interest payments linked to the Six-Month USD LIBOR and the Russell 2000^® Index, while seeking payment of their principal in full at maturity. For each interest payment period, interest will accrue at the Interest Factor of 7.00% per annum only on calendar days with respect to which (a) the Six-Month USD LIBOR as of the applicable Accrual Determination Date is less than or equal to the LIBOR Strike of 6.00% and (b) the closing level of the Russell 2000^® Index as of the applicable Accrual Determination Date is greater than or equal to the Index Strike of 620. Any payment on the notes is subject to the credit risk of JPMorgan Chase & Co.

· Senior unsecured obligations of JPMorgan Chase & Co. maturing April 17, 2027, subject to postponement as described below

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

· At our option, we may redeem the notes, in whole but not in part, on any of the specified Redemption Dates by providing at least 5 business days’ notice. If the notes are redeemed, you will receive on the applicable Redemption Date a cash payment equal to $1,000 for each $1,000 principal amount note redeemed.

· The terms of the notes as set forth below, to the extent they differ or conflict with those set forth in the accompanying product supplement no. 1-I, will supersede the terms set forth in product supplement no. 1-I. In particular, whether the Accrual Provision is satisfied will depend on the Six-Month USD LIBOR and the Index Level on the applicable Accrual Determination Date (rather than on the Six-Month USD LIBOR on a LIBOR Determination Date and the Index Level on an Equity Index Determination Date as described in product supplement 1-I), as set forth below, and interest will be payable to the holders of record at the close of business on the business day immediately preceding the applicable Interest Payment Date or Redemption Date. Please refer to “Additional Key Terms — Accrual Provision,” “Additional Key Terms — Accrual Determination Date,” “Key Terms — Redemption Feature” and “Selected Purchase Considerations — Quarterly Interest Payments” in this pricing supplement for more information.

· The notes priced on April 11, 2012 and are expected to settle on or about April 17, 2012.

Redemption Feature:	At our option, we may redeem the notes, in whole but not in part, on the 17th calendar day of January, April, July and October of each year, commencing April 17, 2013 (each, a “Redemption Date”) by providing at least 5 business days’ notice; provided, however, that if any Redemption Date is not a business day, then such Redemption Date shall be the following business day. If the notes are redeemed, you will receive on the applicable Redemption Date a cash payment equal to $1,000 for each $1,000 principal amount note redeemed. Any accrued and unpaid interest on notes redeemed will be paid to the person who is the holder of record of such notes at the close of business on the business day immediately preceding the applicable Redemption Date.

Additional Key Terms

Interest Payment Dates:	Interest on the notes will be payable quarterly in arrears on the 17th calendar day of January, April, July and October of each year (each such date, an “Interest Payment Date”), commencing July 17, 2012, up to and including the Interest Payment Date corresponding to the Maturity Date, or, if the notes have been redeemed, the applicable Redemption Date.  See “Selected Purchase Considerations — Quarterly Interest Payments” in this pricing supplement for more information.
Accrual Provision:	For each Interest Period, the Accrual Provision shall be deemed to have been satisfied on each calendar day during such Interest Period on which both (a) the Six-Month USD LIBOR, as determined on the Accrual Determination Date relating to such calendar day, is less than or equal to the LIBOR Strike and (b) the Index Level, as determined on the Accrual Determination Date relating to such calendar day, is greater than or equal to the Index Strike.  If the Six-Month USD LIBOR determined on any Accrual Determination Date relating to a calendar day is greater than the LIBOR Strike and/or the Index Level as determined on the Accrual Determination Date relating to such calendar day is less than the Index Strike, then the Accrual Provision shall be deemed not to have been satisfied for such calendar day.
LIBOR Strike:	6.00%
Index Strike:	620
Six-Month USD LIBOR:	For each Accrual Determination Date, the Six-Month USD LIBOR refers to the London Interbank Offered Rate for deposits in U.S. dollars with a Designated Maturity of six months that appears on Reuters page “LIBOR01” under the heading “6Mo” (or any successor page) at approximately 11:00 a.m., London time, on such Accrual Determination Date, as determined by the calculation agent.  If on such Accrual Determination Date, the Six-Month USD LIBOR cannot be determined by reference to Reuters page “LIBOR01” (or any successor page), then the calculation agent will determine the Six-Month USD LIBOR in accordance with the procedures set forth in the accompanying product supplement no. 1-I under “Description of Notes — Interest — The Underlying Rates— LIBOR Rate.”
Index Level:	On any Trading Day, the official closing level of the Russell 2000® Index (the “Index”) published following the regular official weekday close of trading for the Russell 2000® Index on Bloomberg Professional® Service page “RTY Index” on such Trading Day. If a market disruption event exists with respect to the Russell 2000® Index on any Accrual Determination Date, the Index Level on the immediately preceding Accrual Determination Date for which no market disruption event occurs or is continuing will be the Index Level for such disrupted Accrual Determination Date (and will also be the Index Level for the originally scheduled Accrual Determination Date). In certain circumstances, the Index Level will be based on the alternative calculation of the Russell 2000® Index as described under “General Terms of Notes — Discontinuation of an Equity Index; Alteration of Method of Calculation” in the accompanying product supplement no. 1-I.
Accrual Determination Date:	For each calendar day during an Interest Period, the second Trading Day prior to such calendar day.  Notwithstanding the foregoing, for all calendar days in the Exclusion Period, the Accrual Determination Date will be the first Trading Day that precedes such Exclusion Period.
Exclusion Period:	The period commencing on the seventh Business Day prior to but excluding each Interest Payment Date.
Trading Day:	A day, as determined by the calculation agent, on which (a) trading is generally conducted on (i) the relevant exchanges for securities underlying the Russell 2000® Index or the relevant successor index, if applicable, and (ii) the exchanges on which futures or options contracts related to the Russell 2000® Index or the relevant successor index, if applicable, are traded, other than a day on which trading on such relevant exchange or exchange on which such futures or options contracts are traded is scheduled to close prior to its regular weekday closing time, and (b) commercial banks and foreign exchange markets settle payments and are open for general business (including dealings in foreign exchange and foreign currency deposits) in London.
Maturity Date:	If the notes have not been redeemed, April 17, 2027, or if such day is not a business day, the next succeeding business day
Business Day:	Any day other than a day on which banking institutions in the City of New York are authorized or required by law, regulation or executive order to close or a day on which transactions in dollars are not conducted

Selected Purchase Considerations

· PRESERVATION OF CAPITAL AT MATURITY OR UPON REDEMPTION — We will pay you at least 100% of the principal amount of your notes if you hold the notes to maturity or upon redemption, regardless of whether the Accrual Provision is satisfied for any calendar day of any Interest Period. Because the notes are our senior unsecured obligations, payment of any amount at maturity or upon redemption is subject to our ability to pay our obligations as they become due.

· QUARTERLY INTEREST PAYMENTS — The notes offer quarterly interest payments at the applicable Interest Rate. Interest will accrue at a rate per annum equal to the product of (1) the Interest Factor and (2) the Variable Days divided by the Actual Days. Interest, if any, will be payable quarterly in arrears on the 17th calendar day of January, April, July and October of each year (each such date, an “Interest Payment Date”), commencing July 17, 2012, to and including the Interest Payment Date corresponding to the Maturity Date, to the holders of record at the close of business on the business day immediately preceding the applicable Interest Payment Date. If an Interest Payment Date is not a business day, payment will be made on the next business day immediately following such day, provided that any interest payment on such Interest Payment Date, as postponed, will accrue to but excluding such Interest Payment Date, as postponed.

· POTENTIAL QUARTERLY REDEMPTION BY US AT OUR OPTION — At our option, we may redeem the notes, in whole but not in part, on the 17th calendar day of January, April, July and October of each year (each such date, a “Redemption Date”), commencing April 17, 2013, for a cash payment equal to $1,000 for each $1,000 principal amount note redeemed. Any accrued and unpaid interest on notes redeemed will be paid to the person who is the holder of record of such notes at the close of business on the business day immediately preceding the applicable Redemption Date.

· DIVERSIFICATION OF THE Russell 2000^® INDEX — The return on the notes is linked to the Russell 2000^® Index. The Russell 2000^® Index consists of the middle 2,000 companies included in the Russell 3000^™ Index and, as a result of the index calculation methodology, consists of the smallest 2,000 companies included in the Russell 3000^® Index. The Russell 2000^® Index is designed to track the performance of the small capitalization segment of the U.S. equity market. For additional information about the Index, see the information set forth under “The Russell 2000^® Index” in the accompanying underlying supplement no. 1-I.

· TREATED AS VARIABLE RATE DEBT INSTRUMENTS — You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 1-I. You and we agree to treat the notes as “variable rate debt instruments” for U.S. federal income tax purposes. Assuming this characterization is respected, interest paid on the notes will generally be taxable to you as ordinary interest income at the time it accrues or is received in accordance with your method of accounting for U.S. federal income tax purposes.  In general, gain or loss realized on the sale, exchange or other disposition of the notes will be capital gain or loss.  Prospective purchasers are urged to consult their own tax advisers regarding the U.S. federal income tax consequences of an investment in the notes.  Purchasers who are not initial purchasers of notes at their issue price on the issue date should consult their tax advisers with respect to the tax consequences of an investment in the notes, and the potential application of special rules.

Subject to certain assumptions and representations received from us, the discussion in this section entitled “Treated As Variable Rate Debt Instruments”, when read in combination with the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement, constitutes the full opinion of Sidley Austin llp regarding the material U.S. federal income tax treatment of owning and disposing of the notes.

Selected Risk Considerations

An investment in the notes involves significant risks. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement no. 1-I dated November 14, 2011 and the accompanying underlying supplement no. 1-I dated November 14, 2011.

· THE NOTES ARE NOT ORDINARY DEBT SECURITIES; THE INTEREST RATE ON THE NOTES IS NOT FIXED BUT IS VARIABLE, WILL NOT EXCEED THE INTEREST FACTOR AS SET FORTH ABOVE AND MAY BE EQUAL TO 0.00% — The rate of interest paid by us on the notes for each Interest Period is not fixed, but will vary depending on whether the Accrual Provision is satisfied, and whether such Accrual Provision is satisfied will depend on the daily fluctuations in the Six-Month USD LIBOR and the Index Level. Additionally, there is a maximum Interest Rate per annum for any Interest Period equal to the Interest Factor set forth above on the cover of this pricing supplement. This is because the variable Interest Rate on the notes, while determined by reference to the level of Six-Month USD LIBOR and the official closing level of the Russell 2000^® Index as described on the cover of this pricing supplement, does not actually pay an amount based on such levels. Your interest rate on your notes for any Interest Period will not exceed the applicable Interest Factor for such Interest Period, regardless of the decline in Six-Month USD LIBOR or appreciation in the Russell 2000^® Index, which may be significant. Moreover, each calendar day during an Interest Period on which the level of Six-Month USD LIBOR is greater than the LIBOR Strike or the official closing level of the Russell 2000^® Index is less than the Index Strike (each as determined based on the levels of Six-Month USD LIBOR and the Russell 2000^® Index on the applicable Accrual Determination Date) will result in a reduction of the Interest Rate per annum payable for the corresponding Interest Period. If the level of Six-Month USD LIBOR is greater than the LIBOR Strike or the official closing level of Russell 2000^® Index is less than the Index Strike for an entire Interest Period, the Interest Rate for such Interest Period will be equal to 0.00% and you will not receive any interest payment for such Interest Period. In that event, you will not be compensated for any loss in value due to inflation and other factors relating to the value of money over time during such period.

JPMorgan Structured Investments —	PS-3
Callable Range Accrual Notes linked to the Six-Month USD LIBOR and the Russell 2000® Index

· THE INTEREST RATE ON THE NOTEs MAY BE BELOW THE RATE OTHERWISE PAYABLE ON SIMILAR VARIABLE RATE NOtes ISSUED BY US — The value of the notes will depend on the Interest Rate on the notes which will be affected by the level of Six-Month USD LIBOR and the level of the Russell 2000^® Index. If the level of Six-Month USD LIBOR or the level of the Russell 2000^® Index changes beyond the thresholds specified above, the Interest Rate on the notes may be less than returns on similar variable rate notes issued by us that are not linked to Six-Month USD LIBOR and the Russell 2000^® Index, or are only linked to one of the Six-Month USD LIBOR and the Russell 2000^® Index. We have no control over any fluctuations in Six-Month USD LIBOR or the Russell 2000^® Index.

· 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, on any Interest Payment Date or upon redemption by us, 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.

· 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 for our own accounts or on behalf of customers, could cause our economic interests to be adverse to yours and could adversely affect any payments 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 — Risks Relating to the Notes Generally” in the accompanying product supplement for additional information about these risks.

· THE REDEMPTION FEATURE MAY FORCE A POTENTIAL EARLY EXIT — If we redeem the notes, the amount of interest payable on the notes will be less than the full amount of interest that would have been payable if the notes were held to maturity, and, for each $1,000 principal amount note, you will receive $1,000 plus accrued and unpaid interest to but excluding the applicable Redemption Date.

· MARKET FACTORS MAY INFLUENCE WHETHER WE EXERCISE OUR RIGHT TO REDEEM THE NOTES PRIOR TO THEIR SCHEDULED MATURITY — We have the right to redeem the notes prior to the Maturity Date, in whole but not in part, on the specified Redemption Dates. It is more likely that we will redeem the notes prior to the Maturity Date if Six-Month USD LIBOR is below the LIBOR Strike and the Russell 2000^® Index is above the Index Strike resulting in an Interest Rate on the notes that is greater than instruments trading in the market of a comparable maturity and credit rating. If the notes are called prior to the Maturity Date, you may be unable to invest in notes with similar risk and yield as the notes. Your ability to realize the yield on the notes is limited by our right to redeem the notes prior to their scheduled maturity, and our ability to redeem the notes may adversely affect the value of the notes in the secondary market, if any.

· REINVESTMENT RISK — If we redeem the notes, the term of the notes may be reduced to as short as one year and you will not receive interest payments after the applicable Redemption Date. There is no guarantee that you would be able to reinvest the proceeds from an investment in the notes at a comparable return and/or with a comparable interest rate for a similar level of risk in the event the notes are redeemed prior to the Maturity Date.

· AN investment in the notes is subject to risks associated with small capitalization stocks —The stocks that constitute the Russell 2000^® Index are issued by companies with relatively small market capitalization.  The stock prices of smaller companies may be more volatile than stock prices of large capitalization companies.  Small capitalization companies may be less able to withstand adverse economic, market, trade and competitive conditions relative to larger companies.  Small capitalization companies are less likely to pay dividends on their stocks, and the presence of a dividend payment could be a factor that limits downward stock price pressure under adverse market conditions.

· The Six-Month USD LIBOR AND the INDEX may be volatile — The Six-Month USD LIBOR is subject to volatility due to a variety of factors affecting interest rates generally and the rates of U.S. Treasury securities specifically, including:

· sentiment regarding underlying strength in the U.S. and global economies;

· expectation regarding the level of price inflation;

· sentiment regarding credit quality in U.S. and global credit markets;

· central bank policy regarding interest rates; and

· performance of capital markets.

Recently, the Russell 2000^® Index has experienced significant volatility. Increases in the Six-Month USD LIBOR or decreases in the Index Level could result in the Accrual Provision not being satisfied and thus in the reduction of interest payable on the notes.

· WHETHER THE Accrual PROVISION IS SATISFIED WILL DEPEND ON A NUMBER OF FACTORS, WHICH MAY RESULT IN AN INTEREST RATE OF ZERO — The amount of interest, if any, payable on the notes will depend on a number of factors that can affect the levels of the Six-Month USD LIBOR and the Index Level including, but not limited to:

· changes in, or perceptions about, future Six-Month USD LIBOR and Index Levels;

· general economic conditions;

· prevailing interest rates;

· the dividend rates on the equity securities underlying the Russell 2000^® Index; and

· policy of the Federal Reserve Board regarding interest rates.

These and other factors may have a negative impact on the payment of interest on the notes. In addition, these and other factors may have a negative impact on the value of your notes in the secondary market.

· the method of determining the interest rate for any Interest Period may not directly correlate with actual levels of the applicable Six-Month USD LIBOR OR THE INDEX LEVEL — The determination of the Interest Rate payable for any Interest Period will be based, in part, on the Six-

JPMorgan Structured Investments —	PS-4
Callable Range Accrual Notes linked to the Six-Month USD LIBOR and the Russell 2000® Index

Month USD LIBOR and the Index Level, but it will not directly correlate with actual levels of the underlying Six-Month USD LIBOR or the Index Level. We will use the Six-Month USD LIBOR and Index Level on each Accrual Determination Date to determine whether the Accrual Provision is satisfied for any calendar day in the applicable Interest Period.

· 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.

· NO DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the notes, you will not have voting rights or rights to receive cash dividends or other distributions or other rights that holders of the securities included in the Russell 2000^® Index would have.

· HEDGING AND TRADING IN THE UNDERLYINGS — While the notes are outstanding, we or any of our affiliates may carry out hedging activities related to the notes, including trading instruments related to the Six-Month USD LIBOR, the Index and the equity securities included in the Index. We or our affiliates may also trade in the equity securities included in the Index from time to time. Any of these hedging or trading activities as of the Pricing Date and during the term of the notes could affect adversely the likelihood of a redemption or our payment to you at maturity.

· 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, 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.

· Variable price reoffering risks — JPMS sold the notes at market prices prevailing, at prices related to then-prevailing prices or at negotiated prices, provided that such prices were not less than $970.00 per $1,000 principal amount note or more than $1,000 per $1,000 principal amount note. Accordingly, there is a risk that the price you pay for the notes will be higher than the prices paid by other investors based on the date and time you make your purchase, from whom you purchase the notes (e.g., directly from JPMS or through a broker or dealer), any related transaction cost (e.g., any brokerage commission), whether you hold your notes in a brokerage account, a fiduciary or fee-based account or another type of account and other market factors beyond our control.

· MANY ECONOMIC AND MARKET FACTORS WILL IMPACT THE VALUE OF THE NOTES — In addition to the levels of the Six-Month USD LIBOR and the Index Level on any day of an Interest Period, 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 of the Six-Month USD LIBOR and the Russell 2000^® Index;

· the time to maturity of the notes;

· the redemption feature and whether we are expected to redeem the notes, which are likely to limit the value of the notes;

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

· the expected positive or negative correlation between the Six-Month USD LIBOR and the Russell 2000^® Index, or the expected absence of any such correlation;

· interest and yield rates in the market generally, as well as the volatility of those rates;

· the likelihood, or expectation, that the notes will be redeemed by us, based on prevailing market interest rates or otherwise;

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

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

Supplemental Underwriting Information

We expect that delivery of the notes will be made against payment for the notes on or about the settlement date set forth on the front cover of this pricing supplement, which will be the fourth business day following the pricing date of the notes (this settlement cycle being referred to as T+4). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the pricing date or the succeeding business day will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisers.

Hypothetical Examples of Calculation of the Interest Rate on the Notes for an Interest Period

The following examples illustrate how to calculate the Interest Rate on the notes for three hypothetical Interest Periods. For purposes of the following examples, we have assumed that there are 90 days in the applicable Interest Period and that the Six-Month USD LIBOR is less than or equal to the LIBOR Strike of 6.00% per annum. The hypothetical Six-Month USD LIBOR, Index Levels and Interest Rates in the following examples are for illustrative purposes only and may not correspond to the actual Six-Month USD LIBOR, Index Levels or Interest Rates for any Interest Period applicable to a purchaser of the notes. The numbers appearing in the following examples have been rounded for ease of analysis.

Example 1: The Index Level is greater than or equal to the Index Strike on 70 calendar days during the Interest Period. Because the Accrual Provision is satisfied for 70 calendar days and the Interest Factor is 7.00% per annum, the Interest Rate for the Interest Period is 5.44% per annum, calculated as follows:

7.00% × ( 70 / 90 ) = 5.44% per annum

Example 2: The Index Level is greater than or equal to the Index Strike on 45 calendar days during the Interest Period. Because the Accrual Provision is satisfied for 45 calendar days and the Interest Factor is 7.00% per annum, the Interest Rate for the Interest Period is 3.50% per annum, calculated as follows:

7.00% × ( 45 / 90 ) = 3.50% per annum

Example 3: The Index Level is less than the Index Strike on each calendar day during the Interest Period. Regardless of the Interest Factor, because the Accrual Provision is not satisfied on any calendar day, the Interest Rate for the Interest Period is 0.00% per annum.
