Investors are exposed to full downside exposure to the lesser performing of the Underlyings if either Underlying declines by more than the applicable Protection Amount from the Pricing Date to the Observation Date. The notes are callable quarterly at par at the issuer’s discretion.

The payment at maturity will be paid in cash based on the lesser performing of the Underlyings.

Any payment on the notes is subject to the credit risk of JPMorgan Chase & Co.

Return Profile

Interest will be payable monthly in arrears. If an interest payment date is not a business day, payment will be made on the next business day immediately following such day, but no additional interest will accrue as a result of the delayed payment.

Payment at maturity for each $1,000 principal amount note will be a cash payment of $1,000 or, if either of the Underlyings declined by more than the Protection Amount from the Pricing Date to the Observation Date, a cash payment of less than $1,000 that reflects the negative return of the lesser performing Underlying. In the event both Underlyings appreciate relative to their initial values, the investor will receive $1,000 for each $1,000 principal amount invested, subject to the credit risk of JPMorgan Chase & Co. In all cases, payment will include any accrued and unpaid interest.

If the notes are called by the issuer, the investor will receive a cash payment of $1,000 for each $1,000 principal amount note, plus any accrued and unpaid interest.

15month Callable Yield Note

North America Structured Investments

Selected Benefits

• The notes offer a higher interest rate than the yield currently available on debt securities of comparable maturity issued by the Issuer or an issuer with a comparable credit rating

• Monthly interest payments

• The Protection Amount offers some contingent protection against a decrease in the prices of the Underlyings

• Minimum denomination of $1,000 and integral multiples thereof

Selected Risks

• Your investment in the notes may result in a loss. If either of the Underlyings declines by more than the applicable Protection Amount from the Pricing Date to the Observation Date, you could lose up to $875.00 for each $1,000 note.

• Any payment on the notes is subject to the credit risk of JPMorgan Chase & Co. Therefore the value of the notes prior to maturity are subject to changes in the market’s view of JPMorgan Chase & Co.’s creditworthiness.

• Return is limited to the principal amount plus accrued interest regardless of any appreciation of the Underlyings.

• You are exposed to the risks associated with small capitalization companies.

• You are exposed to the risks of the decline in the closing level of each Underlying.

• Your payment at maturity may be determined by the lesser performing of the Underlyings.

• No dividend payments or ownership rights or affiliation with the Underlyings.

• The optional call feature may force a potential early exit. There is no guarantee you will be able to reinvest the proceeds at a comparable interest rate for a similar level of risk.

• Lack of liquidity: JPMorgan Securities LLC, acting as agent for the Issuer (and who we refer to as JPMS), intends to offer to purchase the notes in the secondary market but is not required to do so. The price, if any, at which JPMS will be willing to purchase notes from you in the secondary market, if at all, may result in a significant loss of your principal.

• Many economic and market factors, such as index volatility, time to maturity, interest rates and creditworthiness of the Issuer, will impact the value of the notes prior to maturity.

Investors should be willing to hold their investment until maturity.

• Potential conflicts: we and our affiliates play a variety of roles in connection with the issuance of notes, including acting as calculation agent and hedging our obligations under the notes.

• Tax consequences of the notes may be uncertain.

General

Key Terms

Underlyings:

The S&P 500® Index and the Russell 2000® Index (each an “Underlying,” and collectively, the “Underlyings”)

Interest Rate:

Between 10.00%* and 11.00%* per annum over the term of the notes, assuming no Optional Call, paid monthly and calculated on a 30/360 basis

*The actual Interest Rate will be determined on the Pricing Date and will not be less than 10.00% or greater than 11.00% per annum.

The notes may be called, in whole but not in part, at our option (such an event, an “Optional Call”) on any of the Optional Call Dates set forth below.

Protection Amount:

With respect to each Underlying, an amount that represents 25.00% of the Starting Underlying Level of such Underlying

Pricing Date:

On or about September 30, 2011

Settlement Date:

On or about October 7, 2011

Observation Date**:

December 31, 2012

Maturity Date**:

January 8, 2013

CUSIP:

48125XU61

Interest Payment Dates:

Interest on the notes will be payable monthly in arrears on the 7th calendar day of each month, except for the final monthly interest payment, which will be payable on the Maturity Date or the relevant Optional Call Date, as applicable (each such day, an “Interest Payment Date”), commencing November 7, 2011.  See “Selected Purchase Considerations — Monthly Interest Payments” in this amended and restated term sheet for more information.

Payment at Maturity:

If the notes are not called, the payment at maturity, in excess of any accrued and unpaid interest, will be based on whether a Trigger Event has occurred and the performance of the Lesser Performing Underlying.  If the notes are not called, for each $1,000 principal amount note, you will receive $1,000 plus any accrued and unpaid interest at maturity, unless a Trigger Event has occurred.

If the notes are not called and a Trigger Event has occurred, at maturity you will lose 1% of the principal amount of your notes for every 1% that the Ending Underlying Level of the Lesser Performing Underlying is less than the Starting Underlying Level of such Underlying.  Under these circumstances, your payment at maturity per $1,000 principal amount note, in addition to any accrued and unpaid interest, will be calculated as follows:

$1,000 + ($1,000 × Lesser Performing Underlying Return)

You will lose some or all of your principal at maturity if the notes are not called and if a Trigger Event has occurred.

Trigger Event:

A Trigger Event occurs if the Ending Underlying Level of either Underlying is less than the Starting Underlying Level of such Underlying by more than the applicable Protection Amount.

Underlying Return:

With respect to each Underlying, the Underlying Return is calculated as follows:

Ending Underlying Level – Starting Underlying Level
Starting Underlying Level

Optional Call:

We, at our election, may call the notes, in whole but not in part, on any of the Optional Call Dates prior to the Maturity Date at a price for each $1,000 principal amount note equal to $1,000 plus any accrued and unpaid interest to but excluding the applicable Optional Call Date.  If we intend to call your notes, we will deliver notice to DTC at least five business days before the applicable Optional Call Date.

Optional Call Dates**:

January 9, 2012, April 9, 2012, July 9, 2012 and October 9, 2012

Other Key Terms:

The price to the public includes the estimated cost of hedging our obligations under the notes through one or more of our affiliates.

(2)

If the notes priced today, J.P. Morgan Securities LLC, which we refer to as JPMS, acting as agent for JPMorgan Chase & Co., would receive a commission of approximately $25.00 per $1,000 principal amount note and would use a portion of that commission to allow selling concessions to other affiliated or unaffiliated dealers of approximately $15.00 per $1,000 principal amount note.  The concessions of approximately $15.00 per $1,000 principal amount note include concessions to be allowed to selling dealers and concessions to be allowed to any arranging dealer.  This commission includes the projected profits that our affiliates expect to realize, some of which may be allowed to other unaffiliated dealers, for assuming risks inherent in hedging our obligations under the notes.  The actual commission received by JPMS may be more or less than $25.00 and will depend on market conditions on the Pricing Date.  In no event will the commission received by JPMS, which includes concessions and other amounts that may be allowed to other dealers, exceed $40.00 per $1,000 principal amount note.  See “Plan of Distribution (Conflicts of Interest)” beginning on page PS-95 of the accompanying product supplement no. 192-A-III.

You may revoke your offer to purchase the notes at any time prior to the time at which we accept such offer by notifying the applicable agent.  We reserve the right to change the terms of, or reject any offer to purchase, the notes prior to their issuance.  In the event of any changes to the terms of the notes, we will notify you and you will be asked to accept such changes in connection with your purchase.  You may also choose to reject such changes in which case we may reject your offer to purchase.

You should read this amended and restated term sheet together with the prospectus dated November 21, 2008, as supplemented by the prospectus supplement dated November 21, 2008 relating to our Series E medium-term notes of which these notes are a part, and the more detailed information contained in product supplement no. 192-A-III dated March 10, 2011.  This amended and restated term sheet, together with the documents listed below, contains the terms of the notes and supersedes all other prior or contemporaneous oral statements as well as any other written materials including preliminary or indicative pricing terms, correspondence, trade ideas, structures for implementation, sample structures, fact sheets, brochures or other educational materials of ours.  This amended and restated term sheet amends and restates and supersedes the term sheet related hereto dated September 2, 2011 in its entirety.  You should rely only on the information contained in this amended and restated term sheet and in the documents listed below in making your decision to invest in the notes.  You should carefully consider, among other things, the matters set forth in “Risk Factors” in the accompanying product supplement no. 192-A-III, as the notes involve risks not associated with conventional debt securities.  We urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the notes.

Additional Key Terms

Starting Underlying Level:

With respect to each Underlying, the closing level of such Underlying on the Pricing Date

Ending Underlying Level:

With respect to each Underlying, the closing level of such Underlying on the Observation Date

Supplemental Terms of the Notes

For purposes of the notes offered by this amended and restated term sheet, the concept of a “Monitoring Period,” as described in the accompanying product supplement no. 192-A-III, is not applicable.  Instead, whether a Trigger Event has occurred and your payment, at maturity, if any, will depend on the closing level of each Underlying on a single day (the Observation Date) only, which we also refer to as the Ending Underlying Level.  See “Key Terms — Payment at Maturity” and “Key Terms — Trigger Event” in this amended and restated term sheet for more information.  Accordingly, you should disregard the definition for the “Monitoring Period” in the accompanying product supplement no. 192-A-III, and you should deem references in the accompanying product supplement no. 192-A-III to (i) “the Monitoring Period” to be “the Observation Date,” and (ii) “on any day during the Monitoring Period” or “during the Monitoring Period” to be “on the Observation Date.”

Historical Information

The following graphs show the historical weekly performance of the S&P 500® Index and the Russell 2000® Index from January 6, 2006 through September 16, 2011.  The closing level of the S&P 500® Index on September 19, 2011 was 1204.09.  The closing level of the Russell 2000® Index on September 19, 2011 was 702.23.

We obtained the various closing levels of the Underlyings below from Bloomberg Financial Markets.  We make no representation or warranty as to the accuracy or completeness of information obtained from Bloomberg Financial Markets.  The historical levels of each Underlying should not be taken as an indication of future performance, and no assurance can be given as to the closing level of any Underlying on the Pricing Date or the Observation Date.  We cannot give you assurance that the performance of the Underlyings will result in the return of any of your initial investment.

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

The following table and examples illustrate the hypothetical total return at maturity on the notes.  The “note total return” as used in this amended and restated term sheet is the number, expressed as a percentage, that results from comparing the payment at maturity plus the interest payments received over the term of the notes per $1,000 principal amount note to $1,000.  The table and examples below assume that the notes are not called prior to maturity and that the Lesser Performing Underlying is the S&P 500® Index.  We make no representation or warranty as to which of the Underlyings will be the Lesser Performing Underlying for purposes of calculating your actual payment at maturity.  In addition, the following table and examples assume a Starting Underlying Level for the Lesser Performing Underlying of 1200 and an Interest Rate of 10.00% per annumover the term of the notes and reflect the Protection Amount of 25.00%.  In addition, if the notes are called prior to maturity, your note total return and total payment may be less than the amounts indicated below.  The hypothetical note total returns and total payments set forth below are for illustrative purposes only and may not be the actual note total returns or total payments applicable to a purchaser of the notes.  The numbers appearing in the following table and examples have been rounded for ease of analysis.

(1) A Trigger Event occurs if the Ending Underlying Level of either Underlying is less than the Starting Underlying Level of such Underlying by more than 25.00%.

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

Example 1: The level of the Lesser Performing Underlying increases from the Starting Underlying Level of 1200 to an Ending Underlying Level of 1260 — a Trigger Event has not occurred.  Because the notes are not called prior to maturity and a Trigger Event has not occurred, the investor receives total payments of $1,125 per $1,000 principal amount note over the term of the notes, consisting of interest payments of $125 per $1,000 principal amount note over the term of the notes and a payment at maturity of $1,000 per $1,000 principal amount note.  This represents the maximum total payment an investor may receive over the term of the notes.

Example 2: The level of the Lesser Performing Underlying decreases from the Starting Underlying Level of 1200 to an Ending Underlying Level of 960 — a Trigger Event has not occurred.  Because the notes are not called prior to maturity and a Trigger Event has not occurred, even though the Ending Underlying Level of the Lesser Performing Underlying of 960 is less than its Starting Underlying Level of 1200, the investor receives total payments of $1,125 per $1,000 principal amount note over the term of the notes, consisting of interest payments of $125 per $1,000 principal amount note over the term of the notes and a payment at maturity of $1,000 per $1,000 principal amount note. This represents the maximum total payment an investor may receive over the term of the notes.

Example 3: The level of the Lesser Performing Underlying decreases from the Starting Underlying Level of 1200 to an Ending Underlying Level of 720 — a Trigger Event has occurred.  Because the notes are not called prior to maturity and a Trigger Event has occurred, the investor receives total payments of $725 per $1,000 principal amount note over the term of the notes, consisting of interest payments of $125 per $1,000 principal amount note over the term of the notes and a payment at maturity of $600 per $1,000 principal amount note, calculated as follows:

[$1,000 + ($1,000 × -40%)] + $125 = $725

Example 4: The level of the Lesser Performing Underlying decreases from the Starting Underlying Level of 1200 to an Ending Underlying Level of 0 — a Trigger Event has occurred.  Because the notes are not called prior to maturity and a Trigger Event has occurred, the investor receives total payments of $125 per $1,000 principal amount note over the term of the notes, consisting solely of interest payments of $125 per $1,000 principal amount note over the term of the notes, calculated as follows:

[$1,000 + ($1,000 × -100%)] + $125 = $125

The hypothetical returns and hypothetical payouts 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 payouts shown above would likely be lower.

Supplemental Plan of Distribution

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 amended and restated term sheet, which will be the fifth business day following the expected Pricing Date of the notes (this settlement cycle being referred to as T+5).  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 advisors.
