TURKCELL PROVIDES UPDATE ON NATIONAL ROAMING DISPUTE

Subject: Statement made pursuant to Circular VIII, No: 39 of the Capital Markets Board.

Istanbul Stock Exchange

ISTANBUL        

Special Subjects:

Previously, Turkcell announced that following the failure of the negotiations between Turkcell and Is-Tim Telekomunikasyon Hizmetleri A.S. regarding national roaming, the Telecommunications Authority (“TA”) intervened in the talks and with a written statement, gave Turkcell 30 days to come to an agreement with the operators holding GSM1800 licenses on the basis of issued regulations. Accordingly, Turkcell initiated proceedings before the International Chamber of Commerce (“ICC”) against application of the new regulations and that the TA is not authorized to intervene in the negotiation process.

On January 23, 2004, ICC rendered a decision stating that the case is not under its jurisdiction and Turkcell appealed the decision before the Ankara 21st Court of First Instance. On December 14, 2004 the Court has rejected Turkcell’s request.

Turkcell will apply for an appeal when the written decision regarding the case is submitted.

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.
