Turk Telekom today partially resumed its monthly interconnection payments to Turkcell under the Agreement and paid TL 39.5 trillion (approximately US$ 27.8 million) for June 2003. However, Turkcell believes that this amount is substantially lower than the amount that Turk Telekom should have paid under the Agreement. Although Turkcell currently does not know how the calculation is made, Turk Telekom's basis for calculation violates the decision of the Ankara Seventh Commercial Court of July 17, 2003, that the terms of the Agreement should remain in effect until the parties reach a new interconnection agreement. Turkcell will continue to take necessary legal action against Turk Telekom. Additionally, Turkcell is currently engaged in negotiations with Turk Telekom to reach a consent on the new Interconnection Agreement which should be renewed according to the Access and Interconnection Regulation introduced recently. The new regulation directs that the interconnection tariffs should be based on the cost bases of the signing parties. Background to Dispute In November 2000, Turk Telekom demanded that Turkcell share all interconnection fees equally with Turk Telekom going forward and retrospectively from April 1998 as a result of the favorable decision obtained by the Turkish Electrical Engineer's Society in its lawsuit against Turk Telekom filed with the Ankara Ninth Administrative Court in October 2000. In that lawsuit, the Turkish Electrical Engineer's Society claimed that the interconnection fee regime set out in the Interconnection Agreement between Turkcell and Turk Telekom violated public policy. There are two pending lawsuits filed by Turkcell against Turk Telekom in the Turkish Commercial Courts. In June 2003, Turk Telekom stopped making monthly interconnection payments to Turkcell after the injunction ensuring the continuation of the monthly payments under the Agreement was lifted. However, on July 17, 2003, the Ankara Seventh Commercial Court decided that the terms of the Agreement should remain in effect until the parties reach a new interconnection agreement. 1 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.
