UNX Catalyst(R) Goes Live with International Trading at UBS

NEW YORK, November 18, 2010 - UNX LLC (www.unx.com), a leading provider of innovative trading
technology solutions, now supports international electronic trading with UBS
through the UNX Catalyst trading platform.

Catalyst users can access markets across Canada, Europe and South America
when they trade using UBS direct market access (DMA) and algorithmic trading
strategies. Clients already have had access to electronic trading
capabilities from UBS for the U.S. since 2009.

UNX's CEO, Thomas Kim, states: "We're excited to mark another significant
milestone in the growth of our innovative offering. By making international
trading via UBS available to our clients, they can tap the global firm's
unparalleled footprint of exchanges and alternative liquidity."

UNX will next focus on making UBS's electronic trading capabilities
available in Brazil, where international clients may trade on the Bovespa
using DMA and algorithmic trading strategies, and in Mexico, where UBS
recently launched DMA.

UNX recently enhanced the real-time benchmarking, portfolio and
single-stock trading capabilities of its Catalyst EMS, and continues to
integrate broker algorithms, portfolio trading and other electronic trading
services into the Catalyst Portal.
