Pitney Bowes Joins Siebel Alliance
Program as Strategic Platform Partner
Pitney Bowes Mail and Document Expertise
Complements Siebel eBusiness Applications

Stamford, Conn. and San Mateo, Calif. June 17, 2002 -- Pitney Bowes Inc. (NYSE: PBI), a four-billion dollar global provider of integrated mail and document management solutions, today announced that it has joined the Siebel Alliance Program as a Strategic Partner. Siebel Systems, Inc. (Nasdaq: SEBL) is the world's leading provider of eBusiness applications software. As a result of this alliance, Siebel Systems and Pitney Bowes will co-market solutions and integrate technology that help joint customers better utilize the information contained in their mail, document, and messaging processes and leverage this information for more effective Customer Relationship Management (CRM). Gartner forecasts that the overall CRM market will grow to $25.3 billion in 2002 and will reach $47 billion by 2006.

Siebel Systems provides an integrated family of eBusiness applications software, enabling multichannel sales, marketing, and customer service systems to be deployed over the Web, in call centers, in the field, through reseller channels, and across retail and dealer networks. Pitney Bowes provides core competencies in all aspects of the mail channel from document creation to distribution and receipt in traditional methods as well as the growing medium of digital document delivery. Pitney Bowes will integrate its document technology with Siebel eBusiness Applications, specifically Siebel Marketing 7¾which delivers a comprehensive solution for the complete design, execution, and management of personalized, permission-based campaigns across all channels of customer interaction; and Siebel Call Center 7¾the market-leading application for call centers to create a unique, market-leading solution for customers that utilize technologies from both companies.

"The integration of Pitney Bowes' solutions better enables users of Siebel eBusiness Applications to achieve an accurate and complete view of their customer, across multiple databases, to strengthen their customer interactions," said Brian Baxendale, group president, Pitney Bowes Document Messaging Technologies. "Together Siebel Systems and Pitney Bowes provide an integrated, multichannel, multiline of business, permission-based, personalized, measurable solution that builds long-lasting and profitable customer relationships."

"Joint customers can integrate the Pitney Bowes messaging solutions into a variety of Siebel eBusiness Applications," said Jeffrey Scheel, Vice President and General Manager, Alliances for Siebel Systems. "Pitney Bowes' expertise in statement processing, document tracking, address data quality, and message production and distribution analytics will enable our joint clients to increase response rates and expand their revenue opportunities."

The automated mail channel has many advantages for businesses seeking to manage their customer relationships. Mail is less intrusive than email or telemarketing campaigns and each piece has a longer shelf life. Consumer-focused studies from several sources support the conclusion that the arrival of mail is a meaningful and valued "moment." In addition, the results of direct mail are predictable and consistent from one campaign to another and can be easily refined and targeted for improved results.

The joint Pitney Bowes-Siebel Marketing 7 integration addresses the need to create high-value, customer-focused communications by blending one-to-one messages into mission-critical transactional documents. These are documents that the consumer opens and reviews with greater scrutiny than a general marketing piece, giving the marketing message greater opportunity for penetration and response. Pitney Bowes will integrate its data, address, and addressee quality solutions into Siebel Marketing 7 to ensure the right person in each household receives the right offer.

"The partnership between Pitney Bowes and Siebel Systems enables coordinated interaction with existing and potential customers across all touchpoints-mail, email, Web, parcel, and call center-according to customer preferences," said Mikael Hook of the independent research firm Current Analysis. "The value is that data from the entire process is gathered and made available to optimize each customer experience and better target the next communication."

The Pitney Bowes solution suite will also enable call center service representatives that use Siebel Call Center 7 to more rapidly and accurately respond to billing, invoice, statement, policy, and other physical and/or electronic statement inquiries by providing an "as-built" rendering of the document, thereby increasing customer satisfaction.
