ISWI Subsidiary Launches New Integrated Service with Sportingbet.

WEST PATERSON, N.J. -- Interactive Systems Worldwide, Inc. (NASDAQ: ISWI), through its wholly-owned subsidiary, Global Interactive Gaming Limited (GIG), has launched an enhanced in-run live betting product with Sportingbet Plc, the online sports betting and gaming group.

GIG is providing software and services to allow Sportingbet to offer timely, play-by-play betting throughout the course of a sporting event. The betting markets, which are integrated and offered alongside Sportingbet's existing offerings, are deployed across Sportingbet's websites throughout Europe.

This new service provides GIG with a share of the wagering revenue. GIG is managing certain in-run "play-by-play" wagering markets that are offered in conjunction with other more traditional markets that were already managed by Sportingbet. The management functions performed by GIG will include creating, opening, suspending, closing and settling the markets. The service will also include the setting of the initial odds as well as the subsequent changing of the odds as the game situation dictates. GIG will not be involved in the acceptance of any wagers and Sportingbet will manage the financial risk for these new markets.

Bernard Albanese, President and CEO of ISWI, said, "We are very pleased to have launched this fantastic new service with Sportingbet. To receive this level of endorsement by such a prominent online bookmaker is very gratifying. We expect that this enhanced product, offered throughout Europe on more than twenty websites, will result in an increase in revenues for both companies."

Matt Jellicoe, Sales Director of Sportingbet Europe, said, "We are excited to be able to offer this seamless solution for the innovative betting opportunities made possible by the SportXction([R] )System. We fully expect this service to enhance our own new live betting service by significantly increasing our customers' betting opportunities and helping to increase revenues."

The service is for an initial 18-month term, and Sportingbet will make available the SportXction([R]) system for all of the currently available sports of football, cricket, golf, tennis, rugby, basketball, NFL, snooker and darts. The markets will be offered in multiple languages, and wagers will be accepted in multiple currencies. GIG utilizes the SportXction([R]) System, developed by ISWI, to manage primarily short-term, play-by-play oriented, betting opportunities ("propositions" or "markets") during a live sporting event.
