Today the Ankara Seventh Commercial Court decided that Turk Telekom's decision to offset against the amount of interconnect payments due to Turkcell its receivables in accordance with its claim that interconnect revenues should be shared equally, would be unlawful. The Court also decided that an injunction preventing this offset would remain until a new agreement has been reached and until then the terms of the above Interconnect Agreement would be in effect. Background Information on the Dispute In November 2000, Turk Telekom demanded that Turkcell share all interconnection fees equally with Turk Telekom going forward and retroactively from April 1998. This was the result of a successful lawsuit filed by the Turkish Electrical Engineer's Society against Turk Telekom with the Ankara Ninth Administrative Court in October 2000, which claimed that the interconnection fee regime set out in the Interconnection Agreement between Turkcell and Turk Telekom violated public policy. Although Turkcell was not a party to this lawsuit, the Ankara Ninth Administrative Court annulled the interconnection fee structure set out in the Interconnection Agreement between Turkcell and Turk Telekom. Turkcell obtained an injunction from the Ankara Seventh Commercial Court with respect to Turk Telekom's request until Turkcell reached an agreement with Turk Telekom to replace the annulled interconnection fee structure. On July 3th, 2003, Turkcell was informed by Turk Telekom that this injunction was lifted and Turk Telekom will calculate the sharing of its interconnection revenue with Turkcell on an equal basis. Accordingly, Turk Telekom informed Turkcell on the same day that it would not make the monthly interconnection payment for June 2003, of TL82 trillion (approx. US$58 million as of July 3, 2003) as it decided to offset this figure against the amount due to Turkcell its receivables calculated according to its claim that interconnection revenues should be shared equally. Today's decision by the Ankara Seventh Commercial Court prevents Turk Telekom from any such offsets in the future. www.turkcell.com.tr About Turkcell Turkcell is the leading GSM operator in Turkey with approximately 16.3 million postpaid and prepaid customers as of Mar 31, 2003.
