UBS Investment Bank Announces the Launch of UBS E-TRACS Exchange Traded Note Platform

UBS announced today that eight UBS E-TRACS Exchange Traded Notes
(ETNs) began trading on NYSE Arca. UBS E-TRACS belong to an innovative
class of investment products offering easy access to markets and
strategies that had not been readily available to individual
investors.

ETNs are primarily used as access products, combining exposure to
various markets like futures and commodities with the investment ease
of listed securities. These ETNs track the performance of the UBS
Bloomberg Constant Maturity Commodity Index (CMCI), the first
benchmark commodity index to diversify across both commodities and
maturities.

"UBS is thrilled to enter the ETN market with the launch of these
eight notes," said Kurt Nelson, Managing Director and Head of ETNs at
UBS. "These products offer unique diversification opportunities in a
number of commodities, and give accessibility to the UBS Bloomberg
CMCI to a broader range of investors."

These first eight products are linked to corresponding UBS
Bloomberg CMCI indices. These ETNs trade on NYSE Arca under the
following ticker symbols: CMCI Index (UCI), CMCI Agriculture Index
(UAG), CMCI Livestock Index (UBC), CMCI Industrial Metals Index (UBM),
CMCI Food Index (FUD), CMCI Energy Index (UBN), CMCI Gold Index (UBZ),
and CMCI Silver Index (USV).

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
