TURKCELL SETTLES ITS INTERCONNECTION DISPUTE WITH TURK TELEKOM

Istanbul, Turkey: December 24, 2004 – Turkcell (NYSE: TKC, ISE: TCELL), the leading provider of mobile communications in Turkey, announced today that it has settled its interconnection dispute regarding the call termination pricing, for the period between April 1998 and September 2003, with Turk Telekom by an amicable agreement. The dispute had originated upon Ankara 9th Administrative Court’s cancellation decision of the call termination pricing terms of the interconnection agreement dated April 24, 1998. The settlement talks followed the Cabinet of Ministers’ decree dated August 18, 2004, which set forth the rules and procedures to be followed by the government entities to settle their disputes with third parties through negotiation. The agreement was signed and became effective as of December 24, 2004.

Turkcell accepted and committed to pay TL997,644,669 million (US$725.6 million as of December 24, 2004) after the deduction of Turk Telekom’s collections through November 30, 2004, amounting to TL533,003,258 million (US$387.6 million as of December 24, 2004), including principal, interest, VAT and SCT according to the conditions described below.

The first installment on December 31, 2004 will be equal to the monthly interconnection fee receivables of Turkcell. The remaining balance as of January 1, 2005, will be paid in 17 equal monthly installments starting on January 1, 2005.

Interest will be paid on the installment amounts, according to the payment plan. The monthly interest rate will be calculated from the annual simple interest rate of the most recent TL denominated discount bond issued by the Turkish Treasury before the 15th of each month of the actual monthly installment. The interest payment for each installment will be calculated on the outstanding balance after the last payment.

Based on the Cabinet of Ministers’ decree dated August 18, 2004 and Turkcell’s estimates based on its settlement strategies, Turkcell provisioned for the interconnection dispute in its financial statements for the nine months ended September 30, 2004, for the above mentioned dispute.

FOR IMMEDIATE RELEASE

TURKCELL SETTLED ITS TREASURY SHARE DISPUTE UNTIL MAY 31, 2004 WITH THE TURKISH TREASURY

Istanbul, Turkey: December 24, 2004 – Turkcell (NYSE: TKC, ISE: TCELL), the leading provider of mobile communications in Turkey, announced today that it has settled the dispute on the calculation and payment of Turkcell’s ongoing 15% license fee to the Treasury accumulated from April 1998 through May 2004 and to end the related lawsuits by an amicable agreement. The agreement followed settlement talks conducted under the law dated June 16, 2004, which authorized State owned entities to settle their legal disputes out of court. The settlement agreement has been signed between Turkcell and the Minister of Finance and the Minister responsible for the Turkish Treasury, on behalf of the Turkish Treasury.

The parties agreed to exclude the frequency usage fee and the education fund from the gross revenue calculation upon which the 15% Treasury fee is calculated and to include other disputed items in the calculation for the period between April 1998 and May 2004.

The amount that Turkcell will pay to the Treasury includes both principal and interest. The interest charge is derived from a 1.9% monthly interest rate on the agreement amount, calculated until the last day of the month which the settlement agreement has been prepared, and considers the interconnection revenue calculation methodology applied between Turk Telekom and Turkcell.

According to the agreement, Turkcell agreed to pay TL866,506,909 million (US$630.2 million as of December 24, 2004) to the Treasury, which consists of TL596,704,023 million (US$433.9 million as of December 24, 2004) in principal and TL269,802,886 million (US$196.2 million as of December 24, 2004) in interest.

Turkcell has already paid TL450,000,000 million (US$327.3 million as of December 24, 2004) of the total TL866,506,909 (US$630.2 million as of December 24, 2004) to be paid. The remainder will be paid off in 4 installments. The first installment totaling to TL150,000,000 million (US$109.1 million as of December 24, 2004) will be paid on December 25, 2004 and the remaining balance will be paid in three equal payments no later than the 25th day of each month, starting by January 2005. Interest will be added to each payment, calculated from the previous months average annual simple interest rate of the TL denominated discount bonds issued by the Turkish Treasury.

TURKCELL PROVIDES UPDATE ON INTERNATIONAL VOICE TRAFFIC
INVESTIGATION

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

ISTANBUL    


Special Subjects:

As announced before, although, the license agreement signed between Turkcell and the Telecommunication Authority (“TA”) allows Turkcell to establish necessary infrastructure for the termination of both local and long distance voice traffic and the monopoly of Turk Telekom has ended as of December 31, 2003, the TA has fined Turkcell claiming that Turkcell has violated its license agreement by using infrastructure other than Turk Telekom’s for its services. The fine totaled TL31,730,818,040,000 (approximately US$23.1mn as of Dec. 24, 2004). Turkcell paid this penalty on April 9, 2004 and stated that it will take necessary legal actions against the TA’s ruling.

In response to the lawsuit filed by Turkcell regarding the TA’s ruling, the 10th Chamber of the Council of State in Turkey has issued an injunction to cease the decisions and actions that are the subject of a lawsuit until the case is finalized, but rejected Turkcell’s request for an injunction to cease implementation of the related items of the Telecom Authority’s regulation regarding application of administrative fines to operators. Although the case still continues, this development enables Turkcell to make a claim for the repayment of the fine previously paid.

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.
