KaR-Tel reports receipt of an order to pay from the Savings Deposit Insurance Fund of the Republic of Turkey

Almaty (January 18, 2005)— KaR-Tel today announced that it received an "order to pay" that was purportedly issued by the Savings Deposit Insurance Fund of the Republic of Turkey (the "Fund"). The order, dated as of October 7, 2004, was delivered to KaR-Tel last week by the Bostandykski Regional Court of Almaty. The order states that KaR-Tel owes "debt to the Treasury" in the amount of approximately US$5.5 billion (stated as approximately Turkish Lira 7.55 quadrillion and issued prior to the introduction of the New Turkish Lira which became effective as of January 1, 2005). The order does not provide any information regarding the nature of, or basis for, the asserted debt, other than to state that it is a debt to the Treasury and the term for payment is May 6, 2004. Yesterday, KaR-Tel delivered to the Turkish consulate in Almaty a petition to the Turkish court objecting to the propriety of the order. In addition, yesterday KaR-Tel also delivered a similar petition to the Ministry of Justice of the Republic of Kazakhstan for forwarding to the Ministry of Justice of the Republic of Turkey.

Konstantin Markov, General Director of KaR-Tel, stated, "We do not understand the nature or the grounds of the order as we believe that KaR-Tel does not have any obligations owing to the Turkish Government. 60% of KaR-Tel was previously owned by two Turkish entities. In November 2003, based upon Kazakh court decisions, including a decision of the Supreme Court of Kazakhstan, the interests of the Turkish entities were mandatorily redeemed for their nominal value by KaR-Tel. We believe that this order of the Fund is completely without merit and intend to defend our rights vigorously."

VimpelCom, through indirect subsidiaries, acquired 100% of KaR-Tel in September 2004 for $350 million plus the assumption of approximately $75 million in debt, based on VimpelCom's assessment at the time of the closing of the acquisition. As previously disclosed, just prior to its acquisition of KaR-Tel, VimpelCom received letters from the two Turkish entities whose shares had been mandatorily redeemed, stating among other things that their respective managements had been taken over by the Fund. As of September 30, 2004, KaR-Tel accounted for approximately 3.3% of VimpelCom's consolidated subscriber base.

There can be no assurance that VimpelCom and/or KaR-Tel will prevail with respect to the objections filed (either on substantive or procedural grounds, including that the above-mentioned petitions were filed in a valid and otherwise timely manner in accordance with applicable legal requirements) or that they will not be required to pay amounts owed in connection with the order from the Fund or on the basis of other claims made by authorities from the Republic of Turkey. The adverse resolution of this matter, and any others that may arise, could have a material adverse effect on VimpelCom's business, financial condition and results of operations, including an event of default under VimpelCom's outstanding indebtedness.
