Notes

(1) Represents the performance of the Index based on, as applicable to the
relevant measurement period, the hypothetical backtested weekly Index closing
levels from Sep 28, 2001 through May 2, 2008, and the actual historical
performance of the Index based on the weekly Index closing level from May 6,
2008 through September 30, 2011, as well as the performance of the S and P
GSCI[TM] Excess Return Index ("S and P GSCI[TM]") over the same period. For
purposes of these examples, each index was set equal to 100 at the beginning of
the relevant measurement period. There is no guarantee that Optimax will
outperform the S and P GSCI[TM] or any alternative strategy. Source: Bloomberg
and JPMorgan.

(2) Calculated from the historical returns, as applicable to the relevant
measurement period, of the indices using historical rolling weekly returns. For
any given day, represents the annualized volatility of each index's arithmetic
weekly returns for the 60-index day period preceding that day. The back-tested,
hypothetical, historical annualized volatility has inherent limitations. These
volatility results were achieved by means of a retroactive application of a
back-tested volatility model designed with the benefit of hindsight. No
representation is made that in the future the Index and the S and P GSCI[TM]
will have the volatilities as shown above or that the Index will outperform any
alternative investment strategy. Alternative modeling techniques or assumptions
might produce significantly different results and may prove to be more
appropriate. Actual annualized volatilities may vary materially from this
analysis. Source: Bloomberg and JPMorgan.

(3) On a monthly basis, J.P. Morgan Securities Ltd., or JPMSL, acting as the
Index calculation agent, will rebalance the Index to take synthetic long and
short positions in the Basket Constituents based on mathematical rules that
govern the Index and track the returns of the synthetic portfolio above cash.
The weights for each Basket Constituent will be adjusted to comply with certain
allocation constraints, including constraints on individual Basket Constituents,
as well as the individual sectors. The sum of the weights is zero.

(4) Volatility and correlation are based on daily returns over the past ten
years. Correlation refers to the degree the applicable index has changed
relative to changes in the JPMorgan Optimax Market-Neutral Index. The Sharpe
Ratio, which is a measure of risk-adjusted performance, is calculated as the
annualized ten year return divided by the annualized ten year volatility.

Key Risks

o There are risks associated with a momentum-based investment strategy. The
Index may fail to realize gains that could occur from holding assets that have
experienced price declines, but experience a sudden price spike thereafter.

o The Index may not be successful, may not outperform any alternative strategy
related to the Basket Constituents, or may not achieve its target volatility of
5%.

o The investment strategy involves monthly rebalancing and maximum weighting
caps applied to the Basket Constituents by sector and asset type.

o Changes in the value of the Basket Constituents may offset each other.

o The Index was established on May 6, 2008 and has a limited operating history
The Index may perform poorly in non-trending 'choppy' markets characterized by
short-term volatility.

o The reported level of the Index will include the deduction of a fee assessed
at 0.96% per annum.

o The momentum strategy embedded in the Index may not outperform other
strategies that do not rebalance monthly.

o The Index is not representative of a pure long-only commodities allocation and
is not designed to replicate commodities markets.

o Commodities futures contracts are subject to uncertain legal and regulatory
regimes that may adversely affect the timing and amount of your payment at
maturity.

o Commodities prices may change unpredictably, affecting the Index in
unforeseeable ways.

o If a negative weighting is assigned to a Basket Constituent, signifying a
short position relative to such constituent, there is an unlimited loss exposure
to such constituent and such exposure may result in a significant drop in the
level of the Index.

o Our affiliate, JPMSL, is the Calculation Agent and may adjust the Index in a
way that affects its level. JPMSL is under no obligation to consider your
interest as an investor in securities linked to the Index.
