SAN MATEO, CA., February 28, 2002 - Siebel Systems, Inc. (Nasdaq: SEBL), the world's leading provider of eBusiness applications software, today announced that Victoria-based gas and electricity provider TXU and NSW-based energy supplier Country Energy have both successfully deployed Siebel eEnergy Call Center in line with deregulation of the Australian electricity market from January this year.

Recognizing that customer relationship management (CRM) deployment timeframes can be as swift as two to four months, Siebel eEnergy Call Center, Siebel Systems' call center solution designed specifically to meet the unique needs of the energy industry, was deployed at both Country Energy and TXU in nine and 16 weeks, respectively, providing the functionality required to give online quotations to, and manage contact with, customers shopping around for the best electricity deal.

Country Energy's Siebel eBusiness Applications solution went live on January 1, 2002, and TXU deployed on January 13, 2002, in time for the official opening dates of the electricity market to Full Retail Competition (FRC) in NSW and Victoria, respectively.

"Historically, the concept of customer contact in the energy sector has been equivalent to billing," said Murray Creighton, VP and GM Asia-Pacific, Siebel Systems. "Contestability has put the spotlight onto the value of customer relationships for energy providers. Many of our customers in this sector are viewing their initial compliance-driven Siebel eBusiness implementations as the catalyst for a broader change in business philosophy and processes built around customer satisfaction-a fundamental shift that will equip them for the competitive environment ahead."

At TXU, which serves 510,000 electricity customers in eastern Victoria, as well as 410,000 gas customers in western Victoria, Siebel eEnergy Call Center was deployed to 40 operators in the electricity sales call center based in Melbourne. In addition to providing quotations and collecting information on new customers, the Siebel Call Center solution initiates and tracks customer switching between retailers through integration with TXU's connection brokering system, which in turn interacts with the government-run National Electricity Market Management Company (NEMMCO) Web site that manages customer churn. Siebel eEnergy Call Center also interfaces with TXU's mail house, allowing requests received over the phone for brochure information to be streamlined in real time directly through to the fulfillment center. TXU has also deployed Siebel eEnergy globally, with users both in Texas and the U.K.

David Walker, Operations Manager Customer Services at TXU, said, "Using the industry-specific Siebel eEnergy solution was a big advantage in getting this project live in time for Full Retail Competition. The quotation system had to be deployed very quickly, so using as much out-of-the-box functionality as we could-'keeping it simple'-was a key success factor. It was also essential that we had rigorous project management to carefully manage the scope and schedule of the implementation.

"Looking forward, our initial Siebel eBusiness solution gives us the opportunity to consolidate our gas and electricity CRM systems down the track. Integrating CRM across these two marketplaces will give us one consolidated view of the customer and helps us understand and meet their needs more effectively."

At Country Energy, which serves more than 750,000 customers across NSW and parts of southern Queensland, Siebel eEnergy Call Center was deployed to 45 sales and service call center operators based in Port Macquarie and Queanbeyan.

Patrick Cooper, FRC Project Director, Country Energy, said, "As Australia's newest energy company, Country Energy has a very keen focus on looking after both existing and prospective electricity customers in the newly contestable marketplace. We see our Siebel Call Center solution as an integral part of maintaining a competitive advantage."

PricewaterhouseCoopers was the systems integrator for both deployments and was instrumental to implementation success.
