UBS Announces New Commodity ETN linked to the Dow Jones UBS Commodity Index

NEW YORK--(Business Wire)--
UBS Investment Bank announced today that it has expanded its UBS E-TRACS
Exchange Traded Notes (ETNs) platform by adding a new ETN linked to the Dow
Jones-UBS Commodity Index. The new note called UBS E-TRACS Dow Jones-UBS
Commodity Index Total Return (DJ-UBSCI TR) began trading today on NYSE Arca
under the ticker symbol, DJCI.

The DJ-UBSCI TR is UBS`s first ETN linked to the Dow-Jones UBS Commodity Index,
which UBS purchased from AIG in May 2009. The DJ-UBSCI TR measures
collateralized returns from a diversified basket of 19 commodity futures
contracts from sectors spanning energy, precious metals, industrial metals,
grains and livestock.

"This new note linked to the Dow Jones-UBS Commodity Index offers clients easy
accessibility to a variety of hard to access commodities at a very compelling
price," said Christopher Yeagley, Managing Director and US Head of Equity
Structured Products. "We are thrilled to be able to add the UBS E-TRACS Dow
Jones-UBS Commodity Index Total Return to our stable of ETNs."

ETNs are primarily used as access products, combining exposure to various
markets such as commodities with the investment ease of listed securities. UBS
E-TRACS belong to an innovative class of investment products offering access to
markets and strategies that had not previously been readily available to
individual investors.

"UBS E-TRACS offer unique diversification opportunities in a number of commodity
sectors, and with the addition of the DJ-UBS Commodity Index to the platform, we
now can give access to both of our highly successful commodity indexes, the Dow
Jones-UBS Commodity Index and the UBS Bloomberg Constant Maturity Commodity
Index," said Yeagley.

UBS's 10 existing E-TRACS ETNs track the performance of various UBS Bloomberg
CMCI indexes, like platinum, silver, gold, livestock, food, etc, and are traded
like any other security on NYSE Arca. UBS E-TRACs are senior unsecured notes
issued by UBS AG, and can be bought and sold through a broker or financial
advisor. For more information about UBS E-TRACs, please visit
