SAN MATEO, CA., February 28, 2002 - Siebel Systems, Inc. (Nasdaq: SEBL), the world's leading provider of eBusiness applications software, today announced new and enhanced functionality for Siebel eEnergy 7. Reflecting Siebel Systems' proven domain, industry, and technology expertise, Siebel eEnergy 7 for utilities and energy service providers delivers depth and breadth of functionality in sales, marketing, service, and other customer-touching business processes tailored specifically for the utilities and energy services industries, resulting in faster deployments, high rates of end user adoption, and a rapid return on investment.

Unparalleled CRM Functionality Delivers Compelling Return on Investment
Siebel eEnergy 7 for utilities and energy services launches with the industry's most comprehensive, out-of-the-box eBusiness functionality mapped to support the business processes and best practices of the utilities and energy services industries. Siebel eEnergy 7 meets the specific requirements of these complex industries by delivering new specific enhancements that support integration to existing systems, improve back account and service management, and facilitate complex order management.

More than 100 energy companies worldwide are already benefiting from Siebel eBusiness Applications tailored specifically to the energy industry. Siebel eEnergy has been selected by industry leaders, including TXU, Country Energy, npower, Ruhrgas' Energy Service Center and VECTOR, as their CRM standard. VECTOR owns and operates more than one billion dollars worth of infrastructure assets in New Zealand's largest city, Auckland, and is one of New Zealand's largest electricity networks. Vector selected Siebel eEnergy to streamline its business and customer-facing systems and develop direct lines of communication with its end-customers-the families and businesses that consume electricity across its network.

"We didn't want to do a lot of customization, or build anything from scratch, and we had an extremely tight timeframe for implementation," says Maxine Elliott, General Manager-Commercial, VECTOR. "We evaluated different solutions from the user perspective as well as the technical perspective. We saw the potential of the workflow design and architecture of Siebel eEnergy, and it fit our model closely, both in terms of what we need now, and what we will need in the future. And we saw particular potential in the new Smart Web Architecture of Siebel 7. Siebel eBusiness Applications will help us to reach our customer service targets, such as reducing the time it takes to restore power after an interruption, reducing the average duration of power loss for customers connected to our network, and providing real time information to customers during faults. By partnering with Siebel Systems, we haven't just installed an eBusiness system, we're busy embedding a whole customer philosophy."

Siebel eEnergy 7 is designed specifically for utilities and energy service providers to resolve critical pain points across key business processes, leading to increased revenue and profitability. By implementing Siebel eEnergy 7, energy companies can realize benefits including:

• Billing Efficiencies: Extends the capabilities of the account structure to support typical account hierarchies in the various energy industries. For example, Siebel eEnergy allows companies to capture the corporate structure of business customers, enabling billing to be split among various billing accounts. In addition, the account hierarchy can be used to aggregate bills or service usage.
• Improved Account and Service Management: Includes extensible pre-built customer and service profiles that help utility and energy services companies to capture important information about their customers. Profiles allow companies to track marketing and churn management attributes, billing preferences, credit profiles, and service profiles.
• Complex Order Processing: Delivers out-of-the-box workflows to guide customers, employees, and partners to perform industry standard ordering. For example, with the click of a button, "move" functionality allows a default function to translate existing services to a new location. In addition, supplemental orders can be created to change an order that is currently being provisioned.

Additional enhancements improve the areas of complex pricing, including predefined workflows, business processes, product models, and account structures; premise management; trouble tickets and network management; and billing and credit management. These enhancements are enabling Siebel eEnergy 7 to deliver on key strategic imperatives to the energy and related industries, including the need to target, win, and retain the best customers, accelerate time to profit, increase operational efficiencies, and deliver superior, personalized customer service.

"The energy industry is undergoing continued upheaval due to increased globalization, privatization, deregulation, and ongoing corporate restructuring through merger and acquisition activities," said Jim McCray, General Manager for Siebel Energy. "These emerging companies are now grappling with a new set of issues critical to their success, such as determining which products to sell, which markets and customers to target, and building a business infrastructure to better serve customers and collect revenues. With this in mind, Siebel eEnergy 7 was developed to leverage the industry's best practices for increased customer satisfaction, revenues, and competitive advantage. By delivering the only eBusiness solution developed in close collaboration with the world's leading energy companies, we provide energy companies of all sizes with the most comprehensive suite of packaged applications designed to meet industry-specific 'pain points,' such as managing customer churn, regulatory requirements, and service efficiencies, while ensuring the lowest total cost of ownership."

Smart Web Architecture Enables Rapid Deployment and High User Acceptance
Siebel eEnergy 7 was built on the foundation of the newly announced Siebel 7 platform. With the release of Siebel 7, Siebel Systems introduced the Siebel Smart Web Architecture, the industry's first and only zero-footprint Web architecture that provides high levels of interactivity previously available only from Windows desktop applications. Siebel 7 was built from the ground up to operate in heterogeneous environments and by supporting integration via an "application network," organizations can not only integrate front office and back office systems, but also hundreds of other applications essential to the utility and energy services industries. By offering robust application network support, Siebel eEnergy 7 ensures interoperability with the many applications within a utility or energy services organization's systems environment, including homegrown legacy systems, industry-specific niche applications, and external applications for collaborating with partner systems.

Application Network Support Allows for Seamless Integration with Existing IT Investments
Siebel eEnergy applications have been successfully integrated with most of the common packaged back office applications. In addition, Siebel Systems has been actively engaged with selected application vendors, such as CIS (SPL Worldgroup and Lodestar Corporation) to provide validated integrated solutions.

"In today's rapidly evolving energy marketplace, it is imperative that energy companies invest in customer-focused solutions that are relevant, upgradeable, and allow them the ability to adapt to changing market conditions," said J. Guerry Waters, Senior Vice President of Marketing and Strategy for SPL WorldGroup. "Siebel 7 and CorDaptix assure this flexibility through their power to deliver multipoint integration with customer data across customer-facing and back office systems and operational support applications. Together, we now provide a sophisticated and available alternative that will allow current and future energy customers to excel in delivering 'real' service value to energy consumers worldwide."

Robust Analytical Capabilities Provide Customer and Business Insight
Siebel eEnergy 7 is also shipping with Siebel Analytics 7, which includes visual, prepackaged, and fully configurable reports and interactive dashboards with best practice metrics for sales, marketing, service, partner management, and executive users. All Siebel Industry Applications deliver tailored and robust analytical and reporting capabilities that provide role-based analytics with insight into customer trends and overall business performance.

Automated Upgrade Path Provides Low Total Cost of Ownership
Siebel eEnergy 7 offers a clear and easy upgrade path for customers, including automated upgrade functionality, resulting in reduced deployment times and the lowest total cost of ownership. Unlike most applications software, Siebel eEnergy 7 allows existing customers to employ an automated process to upgrade to the latest version of the application by combining and merging customizations with new functionality on the enhanced platform.
