LEAWOOD, KANSAS — May 6, 2002 — Euronet Worldwide, Inc. (NASDAQ: EEFT), a leading provider of secure electronic financial transaction solutions, today announced Euronet ATM Recharge service agreements with Abbey National plc, the UK bank with relationships in one in three homes, and Orange, the UK's most popular mobile phone service with 12.7 million customers. This service marks the first time that consumers in the UK will be able to add airtime to their prepaid mobile phones via ATMs.

With the implementation of Euronet ATM Recharge, Orange UK's 8.6 million prepaid customers will be able to add minutes automatically to their accounts at any of Abbey National's 3,000 ATMs in bank branches as well as at remote locations. Euronet ATM Recharge is a convenient, secure alternative to vouchers for Abbey National customers with Orange prepay phones, enabling consumers to purchase prepaid minutes 24 hours a day, 7 days a week. Rollout of the recharge service will begin with a pilot project this month, with full coverage across the entire Abbey National ATM network in the UK to be completed by fall 2002.

"Abbey National and Euronet share our commitment to deliver innovative services and practical solutions to our customers," said Gordon Webber, Orange Head of Global Distribution. "This partnership will give our customers the ability to top up wherever, whenever and however they choose. We are delighted to offer our customers greater choice and flexibility in their payment methods and are pleased to be able to offer this new choice considerably ahead of other operators. Orange Belgium, where customers have had access to ATM top ups for three years, has seen 30% of its customers top up their talk time in this way, so the growth potential in the UK is huge."

By adding the recharge functionality to its ATMs, Abbey National expands its customer convenience and increases revenue opportunity. Mobile subscribers follow a simple three-step process. Customers insert their bank cards at an Abbey National ATM, enter their PIN, then select Automatic Recharge for their prepaid phones.

"Abbey National's innovative approach to banking has yet again taken financial services to the heart of where they are needed with a mobile phone prepaid service at ATMs," said Ambrose McGinn, Abbey National Director of Strategic Development. "We are fully committed to improving the convenience of our financial services, and this new service will give customers yet another opportunity to manage their finances in a way that suits them."

Euronet Worldwide offers mobile operators and financial institutions solutions that enable airtime to be added to consumers' prepaid accounts from ATMs, point-of-sales devices and directly from the mobile phone. The company provides its recharge solutions to 11 GSM mobile operators in Egypt, Poland, Hungary, the Czech Republic, Croatia, Norway, Curacao and Indonesia.

"Euronet is leading the way by using our technological expertise to prompt lifestyle breakthroughs for bank and mobile customers alike," said Michael J. Brown, Euronet Worldwide Chairman and CEO. "The synergy created by financial institutions and mobile operators enables us to revolutionize and optimize electronic payments."
