Internet infrastructure services provider says

real-time customer management and billing platform is

critical to Pan-Asian business growth

Portal Software, Inc. (Nasdaq:PRSF), a leading provider of business infrastructure software for broadband, wireless Internet, and next-generation communications services, has signed a contract with @Network, Inc., a pan-Asian Internet infrastructure services provider. Under the terms of the contract, Portal will provide @Network with Infranet(R) software, Portal's real-time customer management and billing platform.

@Network, headquartered in the U.S., has built an advanced Internet network capable of handling mission-critical e-business systems and bandwidth-intensive content distribution. Its infrastructure, footprint, and ability to offer managed network services provides a bridge for organizations wishing to do business in the Asia Pacific region.

@Network, which has opened four Internet Data Centers (IDCs) in the Asia Pacific region since late 1999, chose Infranet to help launch and support a variety of services that expand beyond basic infrastructure and co-location.

"We provide comprehensive e-business solutions, including co-location, hosting, content distribution, and Internet call centers," said Fan Kau, cofounder and president of @Network. "In our business, it is critical to have a flexible billing platform. It enables us to offer a wide range of new services quickly to meet rapidly changing market demands.

The company offers many levels of enhanced network services tailored to meet the global needs of multinationals and companies engaged in e-business across and within the Pacific Rim.

@Network has two IDCs in Taiwan, one in Hong Kong, and another in Tokyo. The company is currently planning its IDC and Internet points of presence in China and Korea. In the meantime, @Network is constantly seeking alliances with other technology companies to extend its Internet backbone to provide better service and a first-class infrastructure to companies doing business in the Asia Pacific region. @Network will roll out Infranet in all locations, starting with Taiwan.

"Portal Software is a leader in providing customer management and billing solutions for IP-based services," said Robert Lau, vice president of Portal Software, Asia Pacific. "IDCs are becoming very popular in Asia. Infranet can provide them with a world-class IP infrastructure solution that supports current and future IP-based service offerings while managing the growth of the customer base."
