WEST PATERSON, N.J., July 22 /EMWNews/ -- Interactive

Systems Worldwide Inc. (OTC Bulletin Board: ISWI) today announced today

that its wholly-owned subsidiary, Global Interactive Gaming Limited

("GIG"), and Hipodromo de Agua Caliente S.A. de C.V. ("Caliente"), have

revised their licensing and technical support agreements originally signed

in August 2006.



    In connection with these revised agreements, GIG will provide software

and services that enable Caliente to offer the Company's enhanced

play-by-play sports betting service on-line on Caliente's Internet website.

It is expected that this version will launch in time for the upcoming

American football season, and will run through the end of the calendar

year.



    Caliente is operating the play-by-play betting service using its own

personnel. The wagering opportunities will be offered in both English and

Spanish to the patrons. GIG will provide initial set-up support, software

customization, and will provide on-going technical assistance. These

services will be provided on a "time and materials" basis. The agreement

specifies an up-front payment to GIG, as well as monthly license fees based

on a share of the revenue derived from the enhanced play-by-play betting

service.



    Under these revised agreements, the SportXction(R) System will no

longer be offered in the Race & Sports Books operated by Caliente.
