I4 Commerce and CyberSource Bring `Bill Me Later(R)` to Merchants Seeking Higher Sales and Lower Costs Through Expanded Payment Choice

New Payment Option Helps Merchants Reach Out to More Customers

TIMONIUM, Md. and MOUNTAIN VIEW, Calif., Oct. 1 -- I4 Commerce Inc., a developer of alternative payment solutions for merchants, and CyberSource Corporation (Nasdaq: CYBS), a leading provider of electronic payment and risk management solutions for enterprise businesses, today announced the integration of I4 Commerce`s new payment method, "Bill Me Later," into CyberSource`s payment processing service, providing online merchants with a powerful new tool to help boost sales and reduce transaction costs.

"With Bill Me Later, merchants can better meet the demands of today`s online shoppers for greater payment security, convenience and choice," said Steve Klebe, Vice President of Strategic Alliances at CyberSource. "Most new payment options are introduced as separate technologies requiring significant implementation and maintenance resources. With this alliance, merchants gain access to Bill Me Later through their existing relationship with CyberSource, making the benefits of this new payment method easily accessible through our standard application programming interface."

Bill Me Later simplifies the catalog and web purchase experience by eliminating the need for a credit card. Customers receive instant purchase approval during the checkout process without providing an account number or needing to complete a lengthy applications process. A monthly bill aggregates all purchases made at Bill Me Later Merchants, allowing the consumer to finance the purchase or pay the balance in full at no charge. Merchants receive authorizations, settlements and reporting in a manner similar to credit card transactions.
