A Postilion customer for more than 10 years, Bank of Blue Valley is at the forefront of regional banking with its unique brand of community banking, community partnership, and commercial banking for all types of businesses from start-ups to major regional businesses. The bank provides Internet banking services to more than 9,000 consumer and business banking users today and chose to implement the newest Postilion Retail Internet Banking solution in order to provide its customers with industry leading usability, increased security, and a more modern look and feel.

"Our bank is known for providing convenient, comprehensive financial services coupled with state-of-the-art technology," said Bob Regnier, President, Bank of Blue Valley. "The Postilion Retail Internet Banking solution has generated tremendous excitement among our employees and customers with new features like the Web-based administrative portal and a number of convenient, email banking alerts. We look forward to working with Postilion to deliver even more innovative solutions to our consumer and business customers in the future."

"Bank of Blue Valley is a community bank with a vision toward innovation and we are committed to helping them deliver the mission critical self-service banking applications that enable superior service and support," said Pierre Naude, President, Postilion Banking. "We are excited about the positive response they have already received from the launch of the Postilion Retail Internet Banking solution and look forward to a continued successful relationship as they move forward with implementing additional Postilion solutions."

Separately, Postilion, a leading provider of software solutions for self-service banking and payments and a division of S1 Corporation (Nasdaq: SONE), today announced the signing of four new Latin American customers: Banco Micasa, Banco Corp Banca, and Banco Banorte, all based in Venezuela, and Banco Mercantil Santa Cruz, headquartered in Bolivia.

Postilion's Latin American presence has now grown to 32 customers across 11 countries. The rich functionality of the Postilion platform allows financial institutions not only to manage their ATM estates and merchant acquiring programs efficiently, but also provide their customers with a superior level of service. To secure these deals, Postilion has worked closely with its Latin American reseller, Advance Service International (ADSI).

"Postilion now has a significant presence and market share in the Venezuelan payments market, and is gaining traction across the Latin American region. Our long-term partnership with Postilion allows us to offer financial institutions a flexible suite of payments products suitable for ATM owners and deployers, merchant acquirers, retailers, and card issuers," says Juan Samaniego, CEO of ADSI.

When Corp Banca and Banco Banorte decided to migrate from their legacy payments switch, they were driven by their desire to move to an open-systems platform, the greater availability of trained resources, and a lower total cost of ownership. Banco Micasa and Banco Mercantil Santa Cruz both cited aggressive growth plans as the leading factor in their selection of Postilion.

These new Latin American customers will use Postilion's functionality in the following ways:

• Banco Micasa Venezuela Banco Micasa will use the Postilion solution for ATM owners and deployers to drive approximately 150 ATMs. The Postilion platform will connect with the MasterCard Debit and Visa networks using off- the-shelf Postilion functionality. Micasa is a credit union, currently engaged in changing its profile to a full-service bank.
• Banco Corp Banca Venezuela Recently acquired by Banco Occidental de Descuento (BOD) Venezuela, Banco Corp Banca selected Postilion to replace its legacy payments platform and to interface with American Express International and Consorcio Credicard (CC), a Venezuelan network.
• Banco Banorte Venezuela Banco Banorte has chosen the Postilion solution for merchant acquirers to drive approximately 10,000 POS terminals across Venezuela.
• Banco Mercantil Santa Cruz Bolivia This bank selected the Postilion solution for ATM owners and deployers to drive more than 150 ATMs connected to their core banking solution, FISA, and the local network, ATC. The bank is Postilion's first customer in Bolivia.

"Our presence in Latin America has grown significantly over the past several years and today's announcement of the addition of four Latin American customers is a gratifying sign of the success we are having in the market," says Doug Parr, SVP and General Manager, Postilion Payments, Americas. "As these customers have noted, Postilion's open-systems platform and modern architecture offer financial institutions the benefits of flexibility, scalability, and reduced total cost of ownership."
