Moscow (August 26, 2004) - Open Joint Stock Company "Vimpel-Communications" ("VimpelCom" or the "Company") (NYSE: VIP) today announced it has won a tender against international bidders and has signed an agreement to purchase "KaR-Tel", the second largest cellular operator in Kazakhstan, for a purchase price of US$350 million plus assumption of approximately $75 million in debt. KaR-Tel holds a national GSM-900 license and currently serves approximately 600,000 subscribers, representing, according to Company estimates, a 31% market share in Kazakhstan.

Recognizing the benefits of local expertise when entering a new country, VimpelCom is also in discussions with a Kazakh partner to sell for cash (at the same pricing terms as paid by VimpelCom) a minority interest of up to 50% minus one share in KaR-Tel. VimpelCom intends to retain control of Kar-Tel, with no less than 50% plus one share ownership. The closing of both the purchase of KaR-Tel by VimpelCom and the sale of a stake in KaR-Tel to a partner are expected to occur in the second half of 2004.

Commenting on today's announcement, Alexander Izosimov, Chief Executive Officer of VimpelCom, said, "We are very pleased to announce this acquisition in Kazakhstan as VimpelCom's first expansion outside of Russia. This move opens a new chapter in our development, reflecting our vision of VimpelCom as an international company with a strong presence in developing markets, particularly within the CIS. Kazakhstan, with the highest GDP per capita in the CIS after Russia and a cellular penetration rate of only 13%, offers tremendous opportunities."

Mr. Izosimov continued, "Building upon our achievements and experience operating across 11 time zones in Russia, we intend to expand decisively into Kazakhstan with the introduction of our Bee Line brand and the implementation of our unified business solutions for IT, marketing, distribution, customer service, billing and network operations."

Kazakhstan is located in Central Asia and borders Russia, Uzbekistan, Turkmenistan, Kyrgyzstan and China. With a population of approximately 15 million, Kazakhstan has the second highest GDP per capita in the CIS (after Russia) and had an annual rate of growth in 2003 of 9.2%. Kazakhstan has significant oil and gas deposits as well as metals and other important minerals. Kazakhstan is the only CIS country to have received investment ratings from both S&P's and Moody's.
