Securities linked to JPMorgan ETF Efficiente 5 Index (the "Strategy") are our
senior unsecured obligations and are not secured debt. Investing in these
securities is not equivalent to a direct investment in the Strategy or any
index fund that forms part of the Strategy.

Investments in securities linked to the Index require investors to assess
several characteristics and risk factors that may not be present in other types
of transactions. In reaching a determination as to the appropriateness of any
proposed transaction, clients should undertake a thorough independent review of
the legal, regulatory, credit, tax, accounting and economic consequences of such
transaction in relation to their particular circumstances. This free writing
prospectus contains market data from various sources other than us and our
affiliates, and, accordingly, we make no representation or warranty as to the
market data's accuracy or completeness. All information is subject to change

included in this free writing prospectus are hypothetical and it should be noted
that the constituents have not traded together in the manner shown in the
composite historical replication of the indices included in this free writing
prospectus. No representation is being made that the indices will achieve a
composite performance record similar to that shown. In fact, there are
frequently sharp differences between a hypothetical historical composite
performance record and the actual record that the combination of those
underlying elements subsequently achieved. Use of Simulated Returns Back-testing

have performed prior to its actual existence. For time periods prior to the
launch of an exchange-traded fund included in the Strategy and such
exchange-traded fund's initial satisfaction of a minimum liquidity standard,
back-testing uses alternative performance information derived from a related
index, after deducting hypothetical fund fees, rather than performance
information for such exchange-traded fund. The results obtained from
"back-testing" information should not be considered indicative of the actual

Overview

The JPMorgan ETF Efficiente 5 Index (the "Index" or the "Strategy" or "ETF
Efficiente") is a member of J.P. Morgan's family of Efficiente indices which
generally seek to provide exposure to a range of asset classes and geographic
regions based on the modern portfolio theory approach to asset allocation. ETF
Efficiente leverages the convenience of exchange-traded funds ("ETF"s) as well
as the rapidly growing investment options available with ETFs to provide
exposure to a wide range of asset classes and regions. The Index selects from a
basket of 12 ETFs (the "ETF Constituents") and the JPMorgan Cash Index USD 3
Month (the "Cash Index"). The ETF Constituents, together with the Cash Index,
are referred to as the Basket Constituents.

Key features of the Index include:

[]   the use of ETFs to provide access to a broad range of asset classes and
     geographic regions;

[]   exposure to developed market equities, bonds (including Treasuries and
     corporate bonds), emerging markets, alternative investments (broad
     commodities exposure, gold and real estate) and inflation;

[]   the weights allocated to the Basket Constituents are dynamic and are
     determined monthly based on a rules-based methodology that targets an
     annualized volatility of 5% or less;

[]   an algorithmic portfolio construction which utilizes momentum and
     correlation across asset classes;

[]   the Index is an excess return index and reflects the weighted performance
     of the Basket Constituents (including reinvested dividends for the ETF
     Constituents) in excess of the Cash Index; and

[]   the Index levels incorporate a fee of 0.50% per annum and are published on
     Bloomberg under the ticker EEJPUS5E.

The table and graph below illustrate the performance of the Index based on the
hypothetical back-tested closing levels from September 28, 2001 through October
29, 2010 and actual performance from October 30, 2010 to September 30, 2011.
Based on the hypothetical back- tested performance, the Index realized
annualized returns of 7.96% per annum over the period, and outperformed both the
S-P 500 Index and the Barclays Capital U.S. Aggregate Bond Index (the "Barclays
Aggregate Bond Index"), on an excess return basis, as well as the S-P 500 on a
price return basis. There is no guarantee that ETF Efficiente will outperform
the S-P 500 Index or the Barclays Capital Aggregate Index during the term of
your investment in securities linked to the Index.

Strategy description

The Index employs an allocation strategy based on modern portfolio theory. The
modern portfolio theory approach to asset allocation suggests how a rational
investor should allocate capital across the available universe of assets to
maximize return for a given risk appetite. The Index uses the concept of an
"efficient frontier" to define the asset allocation of the Index. An efficient
frontier for a portfolio of assets defines the optimal return of the portfolio
for a given amount of risk, using the volatility of returns of hypothetical
portfolios as the measure of risk.

Illustration of the Efficient Frontier

[GRAPHIC OMITTED]

On a monthly basis, J.P. Morgan Securities Ltd., acting as the ETF Efficiente
calculation agent, will rebalance the Index to determine the allocations to the
Basket Constituents based on the mathematical rules that govern the Index. The
weights for each Basket Constituent will be determined subject to certain
weighting constraints, including constraints on the weight of each Basket
Constituent as well as constraints on the sum of the weights of Basket
Constituents within a sector. For more information on the weighting constraints
related to the Basket Constituents comprising the Index, see "What are the
Basket Constituents?". The Index seeks to identify the weights for each Basket
Constituent that would have resulted in the hypothetical portfolio with the
highest return over the previous six months while realizing an annualized
volatility over the same period of 5% or less. Thus, the portfolio exhibiting
the highest return with an annualized volatility of 5% or less is selected, and
the weighting for such portfolio is applied to the Basket Constituents. This
forms the practical application of the modern portfolio theory and the efficient
frontier. No assurance can be given that the ETF Efficiente Index will achieve
its target volatility of 5%. The actual realized volatility of the Index may be
greater or less than 5%.

On each selection date for the monthly rebalancing of the Index, the weighting
algorithm implements the following steps:

[]   ETF Efficiente identifies all Eligible Portfolios as described under "What
     are the Basket Constituents?" and calculates the performance for each
     portfolio for an observation period over the previous six months.

[]   For each Eligible Portfolio, ETF Efficiente calculates the annualized
     realized volatility over that same observation period.

[]   The performance and the volatilities of the Eligible Portfolios are used to
     construct the "efficient frontier."

[]   ETF Efficiente selects the Eligible Portfolio with the strongest
     performance that has an annualized realized volatility equal to or less
     than 5%. If no such portfolio exists, the target volatility is increased in
     increments of 1%, and the selection procedure is repeated until a
     portfolio is identified.
                                                                               3

 
 
 
 

 
 
 


The ETF Efficiente calculation agent will publish the index values for the
Index on Bloomberg, subject to the occurrence of a market disruption event. You
can find the current Index value on Bloomberg under the ticker EEJPUS5E.

There is no guarantee that the concept of an efficient frontier combined with
modern portfolio theory will generate positive returns for the Index or that
other theories applied to the portfolio of the Basket Constituents would not
produce a better result than an investment linked to the Index.

What are the Basket Constituents?

The following table sets forth the Basket Constituents that comprise the Index
and the maximum weighting constraints assigned to each asset as well as
specific groups of assets ("sectors").

Basket Constituents

                               [GRAPHIC OMITTED]

Note: See the relevant disclosure statement for more information on the Index
and the Basket Constituents. An Eligible Portfolio is any hypothetical portfolio
composed of the above Basket Constituents whose weights satisfy the following
weighting constraints:

[]   The minimum possible weight assigned to any Basket Constituent is 0%.
[]   The weight assigned to each Basket Constituent is an integral multiple of 5%.
[]   The maximum possible weight assigned to any Basket Constituent is 20%, with
     the exception of (i) the JPMorgan Cash Index USD 3 Month or the iShares
     Barclays TIPS Bond Fund, each of which have a maximum possible weight of
     50%; and (ii) the iShares Russell 2000 Index Fund, the iShares S-P GSCI
     Commodity-Indexed Trust or the SPDR Gold Trust, each of which have a
     maximum possible weight of 10%.
[]   The maximum possible weight assigned to (i) either the Developed Equity or
     the Bonds sector is 50%; and (ii) either the Emerging Markets or the
     Alternative Investments sector is 25%. In addition, the sum of the weights
     assigned to the JPMorgan Cash Index USD 3 Month and the iShares Barclays
     TIPS Bond Fund cannot exceed 50%.
[]   The sum of the weights assigned to all Basket Constituents will be equal to
     100%.
                                                                               4

 
 
 
 

 
 
 


Historical analysis

The Index aims to provide exposure across a diverse spectrum of asset classes
and geographic regions.

Diversified exposure

As illustrated in the table below, equities (as represented by the S-P 500
Index) and bonds (as represented by the Barclays Capital Aggregate Index) have
historically displayed negative correlation. Correlation can be described as a
measure of the degree to which two components change relative to each other. A
diversified approach to investing would stipulate maintaining exposure to a
variety of asset classes to attempt to generate positive returns in a wide
range of market environments.

Based on the rebalancing methodology and the constraints described in "What are
the Basket Constituents?", ETF Efficiente can dynamically allocate to the
Basket Constituents in response to the current market environment, with the
potential to exploit any low historical correlations exhibited by the Basket
Constituents. The hypothetical correlations below illustrate that returns of
the Index have historically not been overly dependent on either bonds or
equities.

Note: Based on the daily hypothetical back-tested returns. The correlations
shown above are for informational purposes only. Hypothetical, historical
performance of the Index. Future correlations may be higher or lower than the
hypothetical, historical correlations in the summary above. Targeting volatility

As described in "Strategy description," the Index targets an annualized realized
volatility of 5%. The graph below illustrates the hypothetical six-month
realized volatility of the Index as well as that of the S-P 500 Index and the
Barclays Capital Aggregate Index between September 2001 and September 2011.

Volatility is a measurement of the variability of returns. The historical, or
"realized," volatility of a portfolio can be measured in a number of ways. For
the purposes of the graph below, volatility is calculated from the historical
daily returns of the indices over a six-month observation period. For any given
day, the "six-month annualized volatility" is the annualized standard deviation
of the daily returns of the relevant index using the closing levels of the index
during the 126 index- day period preceding that day. For example, for the day,
September 30, 2010, the data point on the graph for that day represents the
annualized standard deviation of the daily returns using closing levels of the
relevant index during the 126 index-days up to and including September 30, 2010.
                                                                               5

Note: The hypothetical, historical six-month annualized volatility levels of ETF
Efficiente, the S-P 500 Index, and the Barclays Aggregate Index, are presented
for informational purposes only. The back-tested, hypothetical, historical six-
month annualized volatility has inherent limitations. These volatility levels
reflect historical performance (and in the case of the Index hypothetical
historical performance). No representation is made that in the future ETF
Efficiente, the S-P 500 Index or the Barclays Aggregate Index will have the
volatilities as shown above. There is no guarantee that ETF Efficiente will
outperform any alternative investment strategy, including the Barclays Aggregate
Index or the S-P 500 Index. Alternative modeling techniques or assumptions might
produce significantly different results and may prove to be more appropriate.
Actual six-month annualized volatilities will vary, perhaps materially, from
this analysis. Please see "Important Information" at the front of this
publication for a discussion of certain additional limitations of back-testing
and simulated returns.

Hypothetical historical sector weightings

The following graph illustrates the hypothetical historical allocation to the
various sectors, the Cash Index (labeled as "Cash") or the iShares TIPS Bond
Fund (labeled as "Inflation") based on the rebalancing mechanics set forth under
the "Strategy description." For a detailed description of which Basket
Constituents make up each sector displayed in this graph, please see "What are
the Basket Constituents?". Although ETF Efficiente rebalances on a monthly
basis, for ease of display, allocations are shown on a semi-annual basis in the
chart below.
                                                                               6

Risks associated with the Strategy

THE STRATEGY COMPRISES NOTIONAL ASSETS AND LIABILITIES--The exposures to the
dynamic basket that tracks the excess returns of the Basket Constituents above
the JPMorgan Cash Index USD 3 Month are purely notional. There is no actual
portfolio of assets to which any person is entitled or in which any person has
any ownership interest.

THERE ARE RISKS ASSOCIATED WITH A MOMENTUM-BASED INVESTMENT STRATEGY--The
Strategy employs a mathematical model intended to implement what is known as a
momentum-based investment strategy, which seeks to capitalize on positive market
price trends based on the supposition that positive market price trends may
continue. This Strategy is different from a strategy that seeks long-term
exposure to a portfolio consisting of constant components with fixed weights.
The Strategy may fail to realize gains that could occur from holding assets that
have experienced price declines, but experience a sudden price spike thereafter.

CORRELATION OF PERFORMANCES AMONG THE BASKET CONSTITUENTS MAY REDUCE PERFORMANCE
OF THE STRATEGY--Performances among the Basket Constituents may become highly
correlated from time to time during the term of your investment. High
correlation during periods of negative returns among Basket Constituents
representing any one sector or asset type that have a substantial weighting in
the Strategy could have a material adverse effect on the performance of the
Strategy.

THE COMMODITY FUTURES CONTRACTS UNDERLYING THE ISHARES S-P GSCI
COMMODITY-INDEXED TRUST ARE SUBJECT TO UNCERTAIN LEGAL AND REGULATORY
REGIMES--The commodity futures contracts that underlie the iShares S-P GSCI
Commodity-Indexed Trust are subject to legal and regulatory regimes that may
change in ways that could adversely affect our ability to hedge our obligations
under the Strategy or your investment linked to the Strategy. Under these
circumstances, we may, in our sole and absolute discretion, determine your
payment at maturity early. Because we will not make this early determination
payment until the maturity date, the amount you receive at maturity will not
reflect any further appreciation of the Strategy after such early determination.

OUR AFFILIATE, J.P. MORGAN SECURITIES LTD., OR JPMSL, IS THE CALCULATION AGENT
AND MAY ADJUST THE STRATEGY IN A WAY THAT AFFECTS ITS LEVEL--The policies and
judgments for which JPMSL is responsible could have an impact, positive or
negative, on the level of the Strategy and the value of your investment. JPMSL
is under no obligation to consider your interest as an investor in securities
linked to the Strategy.

OTHER KEY RISKS:

[]   The Strategy may not be successful, may not outperform any alternative
     strategy related to the Basket Constituents, or may not achieve its target
     volatility of 5%.
[]   The investment strategy involves monthly rebalancing and maximum weighting
     caps that are applied to the Basket Constituents by asset type and
     geographical region.
[]   Changes in the value of the Basket Constituents may offset each other.
[]   An investment in securities linked to the Strategy is subject to risks
     associated with non-U.S. markets, including emerging markets.
[]   The securities linked to the Strategy are subject to currency exchange
     risk.
[]   The Index was established on October 29, 2010, and therefore has no
     operating history.
[]   J.P. Morgan Securities LLC., one of our affiliates, is the sponsor of the
     JPMorgan Cash Index USD 3 Month and of the index that underlies the iShares
     JPMorgan USD Emerging Markets Bond Fund.
