His responsibilities will include managing a number of the Company’s operating functions — Technical Strategy and Development, Information Technology (IT) and Logistics.

Mr. Eric Franke assumes his new position from October 3, 2005. Mr. Adam Wojacki, UMC’s Deputy Director General and Director of Marketing, will serve as Acting Director General of UMC.

The Corporate Development and Strategy functions have been integrated into one division. Ms. Tatiana Evtushenkova, previously Vice-President for Investments and Corporate Development, has been appointed Vice-President for Strategy and Corporate Development.

Mr. Dmitry Prokhorenko, previously Director of Human Resources (HR) at MTS, has been appointed Vice-President for Human Resources. Raising the status of the HR division highlights the importance placed by the Company on applying an efficient staffing policy and implementing uniform talent management standards at MTS.

These new positions have been created within the framework of the management optimization program initiated in 2003. A vital stage of this program was the implementation of a three-tiered management structure comprising of the Corporate Center, Macro-Regional and Regional business units, as well as a greater degree of centralization in such key functions as Strategy, Marketing, Sales and Customer Service, Technical, IT, and Finance and Investments.
