Moscow and New York (June 29, 2005) — Open Joint Stock Company "Vimpel-Communications" ("VimpelCom" or the "Company") welcomes the decision by the Supreme Court invalidating the decision of the Temruksky district court of Krasnodarsky Krai in a case brought by a minority shareholder. The Temruksky district court decision suspended the effectiveness of the provision in the Company's charter requiring the supermajority vote of the Company's board with respect to a variety of strategic and important issues. In addition, the decision required the Company to amend this provision of its charter so that all board decisions, including those where there is a conflict of interest or a decision relating to an interested party transaction, would require a simple majority decision of the Company's board members present and having the right to vote on the issue. The Russian Supreme Court initially stayed the enforcement of the Temruksky district court decision in its decision of April 13, 2005. Today's decision by the Supreme Court is final and does not require any further consideration of the case by a Russian court.
