STAMPS.COM AND HP TEAM UP TO PROVIDE AFFORDABLE INTERNET POSTAGE THROUGH PRINT-TO-MAIL SYSTEM

HP’s LaserJet Print-to-Mail Solution to Be Integrated with Stamps.com Allows
Users to Print Internet Postage on Specialized Mail Pieces in One Easy Step

SANTA MONICA, Calif. – May 1, 2000 – Stamps.com™ (Nasdaq: STMP), the leading provider of Internet mailing and shipping services, partnered with Hewlett-Packard Company (NYSE: HWP), to provide the Stamps.com Internet Postage™ service to small-to-medium size businesses as part of the HP LaserJet Print-to-Mail System, a one-step desktop printing solution. Compatible with the HP LaserJet 4000 or 4050 printers, the solution coupled with other business software services will enable professionals to seamlessly print, fold, seal and stamp business-related documents including payroll checks, billing statements and other office correspondence in minutes.

“HP has partnered with Stamps.com to couple a leading e-service with our award-winning printers,” said Manny Kostas, marketing manager for HP’s Business LaserJet Printing. “The integration of Stamps.com Internet Postage service and the HP Print-to-Mail System offers small businesses a cost effective, all-in-one solution that will automatically print postage on mail documents.”

The desktop mailing system simplifies the sometimes tedious task of folding, stuffing and sealing office mailings. Ideal for companies who service mailings between 50 and 10,000 pieces per month, the Print-to-Mail solution streamlines billing statements, payroll checks, reminder notices, and automatically applies postage, all in one step.

Conveniently attached to the rear output tray of a HP LaserJet 4050 or 4000 printer, the Print-to-Mail accessory allows customers to use forms that replace the envelope and paper used with conventional mail, therefore reducing mail preparation costs. The Stamps.com Internet Postage integration will save additional time by allowing customers to print postage directly on the Print-to-Mail forms as they are fed through the system.

The printing solution also includes software from industry leaders such as Capella Technologies, Mindgate, Moore and Peachtree. The HP LaserJet Print-to-Mail System is available for $649. The Stamps.com integration with the HP LaserJet Print-to-Mail solution will be available later this year.
