WEST PATERSON, New Jersey, January 30 /PRNewswire/ --

Interactive Systems Worldwide, Inc. (Pink Sheets: ISWI) has announced
that its wholly-owned subsidiary, Global Interactive Gaming Limited (GIG),
has extended its agreement with a subsidiary of Sportingbet Plc, the online
sports betting and gaming group, until the end of 2011.

The financial terms of the previous agreement regarding GIG's fees, which
specified that GIG's monthly revenue would be determined by the greater of a
revenue share percentage and a minimum monthly guarantee, are unchanged and
will remain in effect for the duration of the extended agreement. In
addition, Sportingbet has agreed to provide to GIG, in a series of four
quarterly payments, an advance payment of a portion of the next three years'
monthly minimums. The companies have agreed to a schedule of credits to be
provided by GIG to Sportingbet applicable to future monthly service invoices
to offset the advance payments.

As a part of this agreement, ISWI has issued to Sportingbet a 5-year
warrant to purchase 500,000 shares of ISWI common stock at a price of
US$0.50.

Bernard Albanese, the Company's CEO, stated, "We are extremely pleased
with Sportingbet's decision to extend the agreement for another three years.
It validates the uniqueness of our offering, and attests to their
satisfaction with our services. Sportingbet is one of the premier on-line
gaming companies in the world, and we are proud to be associated with them in
this strategic relationship."
