Number One Internet Postage(TM) Company Forms Alliance With The Leader In Home and Office Printing

SANTA MONICA, Calif. – January 18, 2000 – Stamps.com™ (NASDAQ: STMP) today announced a distribution and marketing alliance with Hewlett-Packard Company to provide the cost-effectiveness and time savings of Internet Postage(TM) to new HP customers and the more than 100 million existing HP printer owners. As part of this relationship, Stamps.com’s Internet Postage software will be bundled with select HP OfficeJet products, as well as personal and workgroup HP LaserJet printer installation CDs; and will also be accessible through a co-branded Web page (www.hpaffiliates.com). Stamps.com Chairman and Chief Executive Officer John Payne announced the relationship today at the Thomas Weisel Partners Business-To-Business Conference in Boston.

“This relationship gives Stamps.com a giant leap ahead of its competitors by giving HP customers the power to print postage online using only a PC, printer and an Internet connection,” said Loren Smith, Chief Operating Officer and President of Stamps.com. “Our software-only Internet Postage service gives us a competitive advantage because we are the only solution in the market that can be bundled onto installation CDs. Through this new bundling agreement with HP, Stamps.com will provide HP customers with a more cost-effective and efficient way to manage their mail.”

Stamps.com is the only Internet Postage service that requires no hardware or metering device and no start-up fees or long-term contracts. Stamps.com is also the only Internet Postage provider to offer customer support 24 hours a day, seven days a week by phone, on e-mail or through live messaging.

Stamps.com’s Internet Postage service brings HP’s OfficeJet, personal and workgroup LaserJet printer customers the convenience of printing postage directly from their printers. Select OfficeJet and LaserJet owners will find Stamps.com software conveniently accessible on their installation CD and will also receive free postage and a free month of service when they sign-up and install or download the software. In the near future, HP customers will also have access to Stamps.com’s full-service shipping service to manage all their mail and parcel shipments.
