Stamps.com Prints Its 100,000,000th Internet Postage Stamp Further Solidifying Company’s Industry Leadership

Corporate Milestone Coincides with Signing of Extended Agreement with the United States Postal Service

Santa Monica, Calif. – April 22, 2002 – Stamps.com (Nasdaq: STMP) today announced from the National Postal Forum that it has printed postage for more than one hundred million pieces of mail. In addition, the company finalized an agreement with the United States Postal Service (USPS) to introduce new point-of-purchase displays in more than 2,500 retail post office lobbies. The displays will educate post office visitors on the benefits of Stamps.com Internet Postage™ and encourage adoption of the online service. The deal, which will span across the Midwest and East Coast regions, is a broad expansion of a previous agreement with the USPS that promoted Stamps.com in retail post offices in the California market.

“We’re pleased to be the first Internet postage vendor to reach the 100 million mark, further underscoring our leadership in the Internet postage space,” said Kyle Huebner, Vice President of Marketing and Strategy for Stamps.com. “This accomplishment, combined with the continued support from the USPS demonstrated by this new agreement, further supports our confidence in the widespread adoption of Internet postage.”

These significant milestones come on the heels of continued discussions with the USPS regarding the use of Internet postage as a part of future mail security efforts. “We believe that Internet postage has the potential to help the USPS increase mail security, reduce costs and save consumers and businesses time and money,” said John Wargo, Vice President of Service and Market Development for the U.S. Postal Service. “In light of our recent Transformation Plan, we look to companies like Stamps.com to make postage more accessible to customers and to provide cost-effective, secure mail delivery options.”

Stamps.com launched its Internet postage service in 1999 and was the first company to enable consumers and businesses to print postage any time using just a computer, printer and Internet connection. Stamps.com is currently in the USPS approval process for a new form of postage that will enable customers to print sheets of stamps which are not linked to an address and can be stored for later use. Upon approval, Stamps.com will launch this enhanced version of its current product. Additionally, later this year, the company plans to launch a Web-based version of its current offering that will further simplify the registration process and reduce the time and complexity involved in becoming a Stamps.com customer.
