Notes
(1) Represents the performance of the Index based on, as applicable to the
relevant measurement period, the hypothetical backtested daily Index closing
levels from February 28, 2001 through May 13, 2009, and the actual historical
performance of the Index based on the daily Index closing level from May 14,
2009 through July 29, 2011, as well as the performance of the SandP 500[R] Index
over the same period. For purposes of these examples, each index was set equal
to 100 at the beginning of the relevant measurement period and returns
calculated arithmetically (not compounded). There is no guarantee the Index will
outperform the SandP 500[R] Index or any alternative investment strategy.
Source: Bloomberg and JPMorgan.

(2) Volatility is calculated from the historical returns, as applicable to the
relevant measurement period, of the SandP 500[R] Total Return Index (the
"Underlying Index") over a six-month observation period. For any given day,
represents the annualized standard deviation of the Underlying Index's
arithmetic daily returns for the 126-index day period preceding that day. The
index leverage is the hypothetical back-tested amount of exposure of the Index
to the Underlying Index and should not be considered indicative of the actual
leverage that would be assigned during your investment in the Index. The
back-tested, hypothetical, historical six-month annualized volatility and index
leverage have inherent limitations. These volatility and leverage 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 Underlying Index will have the volatility as shown. Alternative
modeling techniques or assumptions might produce significantly different results
and may prove to be more appropriate. Actual six-month annualized volatilities
and leverage may vary materially from this analysis. Source: Bloomberg and
JPMorgan.

(3) Calculated based on the annualized standard deviation for the ten year
period prior to July 29, 2011.

(4) For the above analysis, the Sharpe Ratio, which is a measure of
risk-adjusted performance, is computed as the ten year annualized historical
return divided by the ten year annualized volatility. (5) Correlation refers to
the degree the SandP 500[R] Risk Control 10% Excess Return Index has changed
relative to daily changes in the SandP 500[R] Index for the ten year period
prior to July 29, 2011.

Key Risks
[] The Index has a limited operating history and may perform in unexpected ways
-- The Index began publishing on May 13, 2009 and, therefore, has a limited
history. SandP has calculated the returns that hypothetically might have been
generated had the Index existed in the past, but those calculations are subject
to many limitations and do not reflect actual trading, liquidity constraints,
fees and other costs.
[] The Index may not be successful, may not outperform the Underlying Index and
may not achieve its target volatility --No assurance can be given that the
volatility strategy will be successful or that the Index will outperform the
Underlying Index or any alternative strategy that might be employed to reduce
the level of risk of the Underlying Index. We also can give you no assurance
that the Index will achieve its target volatility of 10%.
[] The Index is not a total return index and is subject to short-term money
market fund borrowing costs-- As an "excess return" index, the SandP 500[R] Risk
Control 10% Excess Return Index calculates the return on a leveraged or
deleveraged investment in the Underlying Index where the investment was made
through the use of borrowed funds. Investments linked to this "excess return"
index, which represents an unfunded position in the Underlying Index, will be
subject to short-term money market fund borrowing costs and will not include the
"total return" feature or the cash component of the "total return" index, which
represents a funded position in the Underlying Index.
[] The Index represents a portfolio consisting of the Underlying Index and a
borrowing cost component accruing interest based on U.S. overnight LIBOR. The
Index dynamically adjusts its exposure to the Underlying Index based on the
Underlying Index's historic volatility. The Index's exposure to the Underlying
Index will decrease when historical volatility causes the risk level of the
Underlying Index to reach a high threshold. If, at any time, the Index exhibits
low exposure to the Underlying Index and the Underlying Index subsequently
appreciates significantly, the Index
will not participate fully in this appreciation.
