LEAWOOD, KANSAS—Dec. 10, 2003—Euronet Worldwide, Inc. (Nasdaq: EEFT), a leading electronic payments provider, today announced a multiyear ATM Network agreement with ING Bank Slaski, one of Poland's five largest banks.

ING Bank Slaski, with 331 branches, will offer expanded ATM services to their 1.4 million cardholders on Euronet's 450 ATMs in Poland. Now ING Bank Slaski customers will have access to more than 1,000 ATMs, when combining Euronet's ATM count and the bank's 553 ATMs. Euronet enables the bank to offer more convenience and distribution points to customers without any additional bank charges to the customers.

"ING Bank Slaski's major objective is to develop and strengthen its position in the Polish banking sector by providing integrated financial services, while maintaining our customer focus," said Marian Czakanski, ING Bank Slaski, S.A. management board president. "To achieve this objective, we look for business partners that provide modern technology and expansion of distribution channels, as well as providing top quality service. We have found all of these qualities in Euronet in our current software relationship and look forward to expanding on it."

The ING Bank Slaski transactions initiated at Euronet's ATMs will be switched directly to the bank for authorization and settlement. The bank has agreed to minimum monthly transaction amounts within the Euronet network and will pay a fixed fee per transaction to Euronet. As an existing client, the Bank already has Euronet's software suite implemented; therefore implementing the ATM network solution will be quick and easy. ING is the twelfth bank to join Euronet's Poland ATM network. Now, Euronet has ATM network participation agreements with six of Poland's 10 largest retail banks.

"ING Bank Slaski really understands the need to offer their customers added convenience, and Euronet's strategy is to help them meet their goals," said Daniel R. Henry, Euronet president and COO. "Providing comprehensive combination software and network solutions is a win-win for both us and our clients. We are committed to delivering the most effective and convenient secure financial transaction solutions in Poland and throughout Europe."
