WALL STREET SYSTEMS ENABLES BANKS TO DELIVER COMPREHENSIVE ONLINE SERVICES WITH INTERNET EXTENSIONS

New York and London, April 30, 2003 - Wall Street Systems, Inc., a leading
provider of global treasury and capital markets solutions and services,
today announced the launch of its Internet Extensions Hub, enabling banks to
offer a wide range of services to their customers via the Internet. Based on
The Wall Street System Object Toolkit, Internet Extensions gives banks the
ability to brand, customize and extend the functionality of The Wall Street
System® to their customers online.

Using Internet Extensions customers can now obtain competitive rates on a
variety of products, including foreign exchange, money markets and
fixed-income securities; execute trades against these rates and obtain trade
confirmations via the web. This enables them to exploit the full benefit of
online services to make investments and funding decisions. Furthermore it
replaces more traditional proprietary terminals, which are typically both
difficult and expensive to maintain. An additional suite of analytical
features is available to customers for trade analysis and reporting.

A quarter of the top 75 global banks are Wall Street Systems customers.
Internet Extensions provides bank relationship managers and sales desks with
a rich communication channel to their customers. This channel, which
incorporates multiple language capabilities, enables banks to offer a wide
range of services to their clients over the Internet - from front office
pricing and execution through to risk management, analytical and operational
facilities. This gives them the ability to enhance their local customer
relationships through a single global solution. Internet Extensions also
offers enhanced STP by interfacing directly with the bank's back office,
custody, and rate feed systems.

Internet Extensions is a J2EE-compliant, servlet-based application that
dynamically generates HTML rendered in the user's browser. It communicates
with The Wall Street System® core engine using XML via The Wall Street
System Object Toolkit. Using industry-standard branding techniques, such as
eXtensible Stylesheet Language (XSL), banks can ensure the look and feel of
the customer interface is consistent with their own brand guidelines. They
also have the ability to support multiple languages within one single
software platform.

Mike Thrower, director of marketing, Wall Street Systems, said: "Wall Street
Systems remains dedicated to responding to its customers' changing
requirements. We are pleased to be able to offer our banking clientele a way
to enhance their client relationships through a new communication channel.
Through Internet Extensions they are able to offer superior instrument and
currency coverage and greater geographic reach. The potential opportunities
are there for the taking."
