BT Openzone deploys new billing solution

CUPERTINO, CA (June 16, 2004)-Portal Software, Inc., (Nasdaq: PRSF) today
announced that its flagship billing solution has been deployed by BT
Openzone, BT Group PLC's Wireless Broadband business. With Portal's billing
solution, BT is now able to launch a self-sign-on option for its wireless
broadband service and automate provisioning for BT Openzone's corporate
licensees.

The Portal solution has been deployed as a link between BT Openzone's
provisioning and billing systems, which in turn has enabled BT to let
individuals sign up online for the WiFi service. Portal's solution has also
made it possible to automate a manual provisioning of services for BT
Openzone corporate license customers.

"Thanks to Portal, BT Openzone now has automated provisioning for
customers," said Chris Clark, CEO, BT Wireless Broadband. "In addition, the
Portal solution enabled us to launch the self-sign-on facility." BT opted
for Portal, he added, because "it is an industrial-strength product in the
right marketplace and offered the best time to market."

Alan Laing, Portal's vice president and general manager, Europe, Middle
East, and Africa commented, "We are delighted that our solution has enabled
BT to automate provisioning for its BT Openzone corporate customers while
also making it possible for individuals to sign up online for the service.
The fact that the supplementary code required less than six months from
drawing board to going live is another source of satisfaction to us, as it
keeps BT ahead of its competitors in terms of meeting customer requirements
and launching new offerings on its WiFi service."
