Business Payments and Settlement Offering to Strengthen ValiCert e-Pay Secure Solution for Banks, Processors and Enterprises

MOUNTAIN VIEW, Calif., December 24, 2001 -- ValiCert, Inc. (NASDAQ: VLCT), a leading provider of secure solutions for paperless e-Business, today announced a definitive agreement to acquire business payments and settlement intellectual property, key personnel and other assets from privately held Tradenable Inc., of Redwood Shores, Calif., a leader in online financial settlement services. The payments-related intellectual property includes, but is not limited to, software code, trademarks and technical expertise. The acquisition of these assets builds on ValiCert’s strategy of providing leading solutions to specific industries including the financial services and healthcare insurance markets.

Tradenable’s proven software for business payments and settlements has been used by numerous business-to-business marketplaces and has processed over 500,000 payment transactions. Tradenable’s payments and settlement software enhances ValiCert’s recently announced ValiCert e-Pay Secure solution which features a suite of products and services, designed specifically for banks, clearing houses, payment networks and payment processors to allow them to deploy secure payment solutions for trusted e-Payments. Tradenable’s payments and settlement software complements ValiCert’s work in the banking industry, specifically with the Identrus security consortium and with SWIFT’s trusted transaction solutions.

(Note to editors: Please see release titled “ValiCert e-Pay Secure Solution Streamlines Payment Processes and Reduces Costs” dated 10/15/01.)

Under terms of the agreement, ValiCert will issue Tradenable Inc. a total consideration of up to one million shares of common stock for the assets acquired. This acquisition will be accounted for as a purchase and is expected to be closed in the fourth quarter of ValiCert’s fiscal year 2001. The acquisition has been approved by the board of directors of each company and is subject to various closing conditions.

According to TowerGroup, the global banking industry spends approximately $10.8 billion worldwide annually on information technology for payments processing, which represents approximately 12% of the industry's total current annual spending of about $88.8 billion.

“The addition of the Tradenable technology into the ValiCert e-Pay Secure solution will give us the ability to deliver a more robust e-Payments solution which is capable of securely delivering a full range of sophisticated business payment and settlement scenarios to global enterprise customers and their banks and processors,” said Yosi Amram, president and chief executive officer of ValiCert.
