UNX Upgrades Catalyst EMS to Support International Trading and Releases New Version of UNX Software Development Kit (SDK)

New offerings also include analytics from Goldman Sachs and QSG

NEW YORK, September 29, 2010 - UNX LLC (www.unx.com), a leading provider of innovative trading
technology solutions, has upgraded its Catalyst(R) Execution Management
System (EMS), an open-architecture electronic trading solution.

Catalyst now supports international equity trading in major European
markets as well as Canada, Brazil and Mexico. Other platform enhancements
include advanced real-time benchmarking capabilities and enhanced trade
management and OMS functionality.

Ruth Colagiuri, Head of Global Product Management for UNX, comments that
"Extending Catalyst to support international markets represents an important
milestone as we rapidly grow the core EMS capabilities across regions and
asset classes in response to client demand."

UNX also just released Version 4.0 of its Software Development Kit (SDK),
which now includes interfaces to support multi-currency, global market data
and order handling.

Available to clients, broker-dealers, exchanges and third-party
application vendors to develop applications or add-ins for use in Catalyst,
the UNX SDK includes multiple open APIs that provide access to thousands of
callable functions and support a broad range of programming languages. Users
can quickly add functionality, update their offerings and integrate
applications without having to involve the UNX development staff and incur
additional development costs.

Recent additions to the suite of available applications include pre-trade
analytics from Goldman Sachs and QSG's transaction cost analysis product.

Colagiuri further comments, "The SDK empowers market participants to
deliver proprietary content and value-added products directly to their
clients, leveraging the broker-neutral Catalyst Portal as a distribution
channel. The result is a new paradigm that extends beyond just an EMS to
create a community of participants who can access and contribute solutions
according to their business models and trading needs."

"We're seeing an increased demand for pre-trade analytics, and UNX's SDK
allowed us to develop and deploy our analytics to select Goldman Sachs
clients using Catalyst in record time," said Rishi Nangalia, Managing
Director and Head of Business Development, Goldman Sachs Electronic Trading.
"We plan to use the SDK to build and integrate future value-added products
and services into Catalyst."

Both Catalyst and the UNX SDK were built on open, modular architecture
using Microsoft .NET technology-enabling clients to integrate or build
exactly what they need at their discretion, based on their own unique
requirements. UNX is recognized by Microsoft as a pioneer of .NET technology
for the institutional trading community, and was showcased in a 2010
Microsoft Case Study for its use of .NET and WPF technology to create its
next-generation EMS.

"Microsoft is proud that UNX has chosen to champion .NET as the
technology core for their groundbreaking Catalyst EMS and Portal," comments
Joe Shirey, Director of Customer Innovation at Microsoft. "We're excited to
continue our mutual collaboration in delivering meaningful, next-generation
trading technology with the performance, reliability and flexibility that
customers require to adapt to changing market conditions and structures
quickly," he adds.
