Special Subjects:

This is an additional announcement following our previous announcements on January 21, 2009 regarding Cosmofon, a company that operates in Macedonia and on January 27, 2009 regarding the capital advance payment to Turktell Bilisim Hizmetleri A.S(“Turktell Bilisim”):

Cosmofon’s main shareholder Greece based operator OTE started a process for the sale of Cosmofon, which is the second largest GSM operator with 650,000 subscribers and 30% market in Macedonia, where population is 2 million.

The non-binding offer that our company had submitted in this context on December 17, 2009 is for us to be able to get involved in this process with respect to the required procedures, and just to have access to the necessary data for us to make a final evaluation on this investment opportunity in the country. Currently, no definitive decision has been taken by our Board of Directors related to this subject.

As per our company’s Board of Directors’ decision on January 27, 2009, it had been decided to pay capital advance to our 100% subsidiary Turktell Bilisim Servisleri A.S. (“Turktell Bilisim”) in the amount of TL250,000,000. Aforementioned capital advance will be, in general, used in 2009 for working capital and investment needs of the direct subsidiaries of Turktell Bilisim operating in Turkey. Capital advance payment will be added to Turktell Bilisim’s capital based on the decision that will be taken during Turktell Bilisim’s 2009 General Assembly meeting.

We hereby confirm that the above-mentioned explanations are furnished as per the provisions of the Communiqué Serial no VIII/39, that they reflect all information we have gathered so far, that they are in accordance with our corporate documents, that we have used all endeavors to collect the complete and true related information and that we assume the responsibility for this disclosure.
