Moscow and New York (November 11, 2005) - Open Joint Stock Company "Vimpel-Communications" ("VimpelCom" or the "Company") (NYSE: VIP) today announced that, following the shareholder approval at the extraordinary meeting of shareholders held on September 14, 2005 (the "EGM"), it has consummated the purchase of CJSC "Ukrainian Radio Systems" ("URS") for an aggregate cash purchase price of $231.3 million. This price includes the purchase price of $206.5 million, plus certain expenditures in the amount of $24.8 million incurred by URS with prior approval from VimpelCom in accordance with the EGM approval. VimpelCom also assumed debt of approximately $23.5 million (including $22.8 million of indebtedness owed to an affiliate of the sellers).

Commenting on today's announcement, Alexander Izosimov, Chief Executive Officer of VimpelCom, said, "We are very pleased to announce this acquisition in Ukraine as VimpelCom's second expansion outside of Russia. We believe our entry into Ukraine is strategically important for VimpelCom and will increase shareholder value."

Following VimpelCom's acquisition of URS, Ericsson, a leading telecom equipment supplier, agreed to swap URS' existing equipment. Ericsson will pay approximately $52.6 million in cash for the existing equipment. URS has agreed to purchase $200 million worth of equipment and services from Ericsson to build out its network during the next three years. This agreement is part of an overall deal for the VimpelCom Group, under which it intends to purchase $500 million of equipment and services from Ericsson at an advantageous pricing level.

Commenting on this news, Mr. Izosimov said, "We are happy to expand our partnership with Ericsson into Ukraine. As a result of this agreement, we will be able to upgrade the network with state-of-the-art equipment and have tangibly reduced the originally budgeted level of investments required to build out the URS network through 2007."

Consistent with its commitment to act in the best interests of all of VimpelCom's shareholders, VimpelCom's management continued to communicate with Telenor following the EGM in an effort to address issues raised by Telenor regarding the URS acquisition, including the amount of investment needed for the URS acquisition and development. However, despite management's efforts to find an amicable resolution, Telenor has not yet withdrawn its previous threats, including its threat to take legal action against VimpelCom and its management to challenge the legality of the URS acquisition. To date, VimpelCom is not aware of any lawsuits filed by Telenor with respect to the EGM or VimpelCom's acquisition of URS.

VimpelCom has previously received several letters from Telenor challenging the sufficiency of the corporate authority of the decision of the VimpelCom shareholders approving the acquisition of URS at the EGM. Telenor stated in its most recent letter to VimpelCom's management that it reserves its rights to challenge the URS acquisition, apparently even after it is consummated. Telenor also stated that "....even if you were to succeed in causing VimpelCom to acquire URS, in addition to Telenor challenging the validity of such acquisition, Telenor's nominees on VimpelCom's Board will have the ability to vote against (and block) the approval of any change in VimpelCom's business plan to include expansion in Ukraine through the acquisition of URS, as well as any increase in VimpelCom's budget for the purpose of funding URS."

Commenting on the situation with Telenor, David Haines, Chairman of VimpelCom's Board, stated, "We regret that Telenor has not expressed support for this important transaction after it has been approved by an overwhelming majority of our public shareholders. We are also disappointed with Telenor's additional threat that their nominees to the Board of VimpelCom might "block" the approval of the Company's business plan and budget related to funding of URS. This would be an affront to the clear will of our shareholders and the principles of good corporate governance."

As previously disclosed, at the EGM held on September 14, 2005, shareholders approved the acquisition of URS as an interested party transaction. Approximately 89% of the votes cast by public shareholders who participated in the EGM (excluding Telenor and Eco Telecom Limited) were voted in favor of the transaction. In addition, as previously disclosed, at its meeting on September 16, 2005, VimpelCom's Board re-affirmed the validity of the shareholder decision of the EGM by a simple majority vote.

URS has a GSM-900 license that covers the entire territory of Ukraine, which has a population of approximately 47.6 million. URS also has a GSM-1800 license that covers 23 of Ukraine's 27 administrative regions (excluding City of Kyiv, the Kyiv Region, the Dnipropetrovsk Region and the Odessa Region).
