Open Solutions Canada Selects Hypercom’s HBNet for One of Canada’s Largest Off-Premise ATM and POS Networks

PHOENIX and GLASTONBURY, May 21, 2008 – Open Solutions Inc.® and Hypercom Corporation (NYSE: HYC) today announced HBNet, Inc., a Hypercom® subsidiary, will provide high speed transaction transport services for Open Solutions Canada, the Canadian subsidiary of Open Solutions, which operates one of Canada’s largest off-premise ATM and point-of-sale networks. Open Solutions is a leading provider of integrated enabling technologies for financial service providers across the United States, Canada and internationally.

“HBNet brings us the exact specifications we need in terms of stability and security that would be impossible to replicate internally,” says Rob Palin, general manager of the Payment Solutions Group at Open Solutions Canada. “We believe HBNet is the fastest and most reliable network and that it will make our payment processing in Canada even more competitive.”

The use of HBNet will enhance Open Solutions Canada’s ability to smoothly and securely process millions of ATM and POS transactions each month to financial institutions. HBNet’s unparalleled performance is achieved through multiple network and equipment redundancies that guarantee the seamless routing of all transactions. HBNet also provides the industry’s highest level of security for dial and Internet transaction processing.

“Open Solutions Canada is a premiere Canadian account and one that validates HBNet’s offering of performance, price, service and know-how,” says Connie Festa, HBNet Vice President Network Services at Hypercom.

Hypercom’s HBNet network speeds the authorization and processing of electronic transactions for retail point-of-sale, financial, government, health care and other customers in both the dial and IP POS markets.

HBNet is powered by robust, ultra high-density MegaNAC® 180 Network Access Controllers (NACs) strategically positioned within the North American Public Switching Telephone Network (PSTN) and at processor data centers. It supports all POS terminal protocols at any modem speed up to V.92 and provides uninterrupted service with no single point of failure, seamless load balancing, state-of-the-art Web-based reporting, and simple all-inclusive pricing.
