DXO PowerShares DB Crude Oil Double Long ETN
OLO PowerShares DB Crude Oil Long ETN
SZO PowerShares DB Crude Oil Short ETN
DTO PowerShares DB Crude Oil Double Short ETN

(collectively, the “PowerShares DB Crude Oil ETNs”) are
the first United States exchange traded products that
provide investors with a cost-effective and convenient
way to take a long, short or leveraged view on the
performance of an oil-based commodity index.

All of the PowerShares DB Crude Oil ETNs are based
on a total return version of the Deutsche Bank Liquid
Commodity Index—Oil, which is composed of certain
crude oil futures contracts. The Long and Double
Long ETNs are based on the Optimum Yield™ version
of the Index, and the Short and Double Short ETNs
are based on the standard version of the index.
