(the “ADSs”) of WiderThan Co., Ltd, a company with limited liability organized under the laws of the Republic of Korea (the “Company”), at a purchase price of $17.05 per Common Share and per ADS (or any higher price per Common Share and per ADS that is paid in the tender offer the “Offer Price”), net to the seller in cash without interest thereon, less any required withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase dated September 29, 2006 (which, together with any amendments and supplements thereto, collectively constitute the “Offer to Purchase”) and in the related Letter of Transmittal (which, together with any amendments or supplements thereto, collectively constitute the “Offer”).
