The Tax Office delivered to Turkcell a notice in 2002, based on the board of
accounting experts of the Ministry of Finance opinion stating that GSM licensees
in Turkcell should pay VAT on the ongoing 15% license fee paid to the Turkish
Treasury starting from April 1998. Turkcell began discussions with the Tax
Office to discuss their deficiency notice before initiating a legal action.

Even though, there were no legal actions taken, Turkcell booked a provision in
its Turkish Lira accounts as of December 31, 2002; TL 154.5 trillion for the VAT
in the balance sheet which will be offset by a VAT recoverable and TL 353.4
trillion in the profit and loss statement for the interest and penalty fees.

Turkcell initiated the process to benefit from the new Tax Amnesty Law that has
entered into force in February 2003 for the amounts covering the April 1998 -
November 2001 period. Due this fact, Turkcell will reverse the provisions both
for the VAT and the interest and penalt fees correspoding to the April 1998 -
November 2001 period amounting to TL 331 trillion in its first quarter 2003
financial statements.

In January 2002, Turkcell applied to the Telecommunication Authority ("Telecom
Authority") requesting the Telecom Authority to review the protocol obligating
Turkcell to collect frequency usage fees from the taxpayers using mobile phones.
stating that it was impossible to collect these fees from prepaid subscribers.
In February 2002, the Telecom Authority requested us to pay the frequency usage
fees in line with the existing regulation with Turkcell bearing the risk of
non-collection. Upon this request Turkcell filed a lawsuit at the Ankara 7th
Court of First Instance against the Telecom Authority requesting cancellation of
the protocols obligating it to collect the frequency usage fees from the
subscribers and to pay it to the Telecom Authority. In July 2002, the court
decided in favour of Turkcell. Telecom Authority has appealed the decision. The
frequesncy usage fees from prepaid subscribers amount to TL 52.3 trillion for
2002 and TL 76.2 trillion for 2003 and Turkcell has not made any provisions in
its consolidated financial statements.

Turkcell has been informed that the Supreme Court has annuled the decision of
the Ankara 7th Court of First Instance. Turkcell will take necessay actions and
initiate legal procedures about this decision.



We hereby confirm that the above-mentioned explanations are furnished as per the
