On April 24, 2006 Mr Vsevolod Rozanov was appointed to the position of Vice-President, CFO. He was previously Deputy General Director for Economics and Finance at Comstar – United TeleSystems OJSC (Comstar UTS).

Commenting on Mr Rozanov’s appointment, the Chairman of MTS’ Board of Directors and General Director of Sistema Telecom Sergey Schebetov said: “A top priority for MTS as dictated by its shareholders is to increase the Company’s efficiency and market capitalization. In order to do this, MTS needs to further strengthen its financial planning, maintain flexible cost management and have a clear understanding of investors’ expectations. In our opinion, Mr Rozanov possesses the relevant work experience needed at MTS. On the one hand, he worked for many years in management consulting and will be able to provide an objective view of the Company so as to propose effective professional solutions. On the other hand, he played an active role in the integration of Sistema’s fixed—line operators and in the successful Initial Public Offering (IPO) of Comstar UTS in February 2006.”

The acting President and CEO of MTS, Mr Leonid Melamed commented: “I have known Mr Vsevolod Rozanov for a long time. He possesses the required management experience in both the financial and the telecommunications industries. His appointment is an obvious strengthening of our management team at an important stage for the Company.”

Boris Podolski, the acting CFO, will return to his position as MTS’ Director of Corporate Reporting and Compliance.
