Lillian Acquisition has accepted for payment all shares of Golden Telecom common stock that were validly tendered during the initial offering period and will make payment to the depositary for the accepted shares promptly.

In addition, VimpelCom announced that Lillian Acquisition has elected to provide a subsequent offering period for all remaining shares of Golden Telecom common stock to permit stockholders who have not yet tendered their shares, due to technical difficulties in the tendering process or otherwise, the opportunity to do so.  This subsequent offering period will commence immediately and will expire at 5:00 p.m., New York City time, on Tuesday, February 26, 2008.  All shares of Golden Telecom common stock properly tendered during the subsequent offering period will be accepted, and tendering stockholders will receive the same price of $105.00 per share in cash.  No shares of Golden Telecom common stock tendered during the initial offering period or the subsequent offering period may be withdrawn.

Following the subsequent offering period, VimpelCom Finance B.V., a direct wholly-owned subsidiary of VimpelCom, and Lillian Acquisition intend to effect a merger of Lillian Acquisition into Golden Telecom. In connection with the merger, all remaining Golden Telecom stockholders who did not tender their shares in the tender offer (other than those, if any, properly perfecting dissenters’ rights) will receive the same $105.00 per share in cash paid in the tender offer.
