Commences Consent Solicitation for its 12.75% Senior Notes Due 2005 Istanbul, Turkey and Curacao, Netherlands Antilles-September 19, 2003-Turkcell Iletisim Hizmetleri A.S. ("Turkcell"; NYSE:TKC, ISE:TCELL), a Turkish joint stock company, and Cellco Finance N.V. ("Cellco"), a Netherlands Antilles limited liability company, announced today that on September 19, 2003, Cellco will commence a solicitation of consents from the holders of its 12 3/4% Senior Notes due 2005 to a proposed amendment to the indenture governing the Senior Notes (the "Senior Notes Indenture"). The Solicitation is being made pursuant and subject to the terms and conditions set forth in Cellco's Consent Solicitation Statement, dated September 19, 2003, and related documents. The proposed amendment would permit Cellco to, among other things, redeem, prepay or purchase its subordinated indebtedness, including its 15% Senior Subordinated Notes due 2005, prior to any scheduled maturity, prepayment or sinking fund payment, by using the proceeds of permitted investments or restricted payments (as such terms are defined in the Senior Notes Indenture) made by Turkcell in compliance with the covenants set forth in the Senior Notes Indenture. Adoption of the proposed amendment requires the consent of the holders of at least a majority of the principal amount of the Senior Notes outstanding. Cellco will pay a consent fee of $15 per $1,000 principal amount of Senior Notes, payable only to holders who validly deliver their consents prior to the consent expiration date and subject to other conditions set forth in the consent solicitation documents being sent to the holders of the Senior Notes. Holders who do not consent to the proposed amendment will not receive a consent fee. The consent solicitation will expire at 5:00 p.m., New York City time, on October 3, 2003, unless terminated or extended. Consents may be revoked prior to such date and time but may not be revoked thereafter. Cellco's sole business is to issue debt securities and lend the proceeds of those debt securities to Turkcell.
