MOSCOW, Russia, and ST. LOUIS, MO — March 16, 2004 — "Vimpel-Communications" ("VimpelCom") (NYSE: VIP), a leading provider of telecommunications services in Russia, and Amdocs (NYSE: DOX), the world's leading provider of billing and CRM for true integrated customer management, today announced that VimpelCom has successfully deployed Amdocs ClarifyCRM.

By implementing Amdocs ClarifyCRM, VimpelCom becomes the first Russian wireless telecommunications company to deploy an integrated customer management solution.

"In order to create a truly differentiated service experience for our growing base of customers, VimpelCom requires a system with the flexibility and scalability to support our frequently changing business processes and aggressive nationwide expansion," said Jere Calmes, Vice President of Customer Operations and Product Management at VimpelCom. "The Amdocs solution improves VimpelCom's operational efficiency, allows us to put our customers at the center of our business, and provides us with the advanced customer care capabilities and functionality critical for cost efficient and rapid expansion."

The initial rollout of Amdocs ClarifyCRM is complete in Moscow and the regional branches of the Central Super Region, currently serving approximately 7 million Bee Line customers. Throughout 2004, VimpelCom intends to deploy Amdocs ClarifyCRM across the remaining super regions of VimpelCom's growing nationwide footprint. This deployment also marks the first CRM system rollout for Amdocs in Russia.
