As we have stated before, with regards to the finalization of the 1st private GSM operator tender in Iran, to which we are a party through our stake in Irancell Consortium, the Iranian Telecommunication Ministry had set November 21, 2005 as the deadline for both our Company and the local partners of the Irancell. We also stated that we would work towards finalization of the Irancell project together with our local partners within the provided timeframe.

Although our efforts to finalize an acceptable structure among the consortium members of Irancell continue, the issue still remains unsettled as of this date. We have currently not been notified by the Authorities regarding any resolution of the first private GSM operator tender in Iran, which was won by the Irancell Consortium.

In case any material development occurs with regards to this subject, Turkcell will make necessary announcement according to the Circular VIII, No: 39 of the Capital Markets Board regulations.

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 endeavours to collect the complete and true related information and that we assume the responsibility for this disclosure.
