This is an announcement as per the letter of Istanbul Stock Exchange dated June 21, 2005.

As per the letter sent by Istanbul Stock Exchange, in various news sources, Iranian officials stated that Turkcell has been excluded from the first private GSM license process in Iran.

There is no official information provided to our Company by Iranian officials regarding this issue. As we have indicated in several announcements, we still believe in the Iranian market and we are working to establish necessary conditions.

We believe that, in a structure in which, the management rights of Irancell, principally at General Shareholders and Board of Directors levels, are determined in accordance with the related local laws and regulations with the participation of Iranian private sector companies and our participation, and the parties fulfill their financial contribution proportionate to their stake in line with the business plans, Irancell consortium can be formed rapidly.

We do not have information regarding the basis of the decisions related to the above mentioned news but we are evaluating the potential outcome and if necessary will take legal actions.

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.
