      This Amendment No. 7 to the Tender Offer Statement on Schedule TO (this “Amendment”), filed with the Securities and Exchange Commission (the “SEC”) on November 27, 2006, amends and supplements the Tender Offer Statement on Schedule TO filed with the SEC on September 29, 2006 (the “Initial Statement”) by (i) RN International Holdings B.V., a private company with limited liability organized under the laws of the Netherlands (the “Offeror”) and an indirect wholly-owned subsidiary of RealNetworks, Inc., a Washington corporation (the “Parent”) and (ii) the Parent. This Amendment relates to the offer by the Offeror to purchase all outstanding common shares, par value KRW500 per share (the “Common Shares”) and all outstanding American Depositary Shares, each representing one Common Share and evidenced by an American Depositary Receipt issued by JP Morgan Chase Bank, N.A. (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”). Following the expiration of the Offer (as the same may be extended pursuant to Article I of the Combination Agreement), the portion of the Offer consideration to be paid in exchange for ADSs will be delivered to Mellon Investor Services LLC (the “ADS Depositary”) and the portion of the Offer consideration to be paid in exchange for Common Shares will be delivered to Samsung Securities Co., Ltd. (the “Common Share Depositary”). Holders of ADSs will receive the Offer Price in U.S. dollars, net to the seller in cash without interest thereon, less any required withholding taxes. Holders of Common Shares will receive the Korean Won equivalent of the Offer Price, calculated by converting the Offer Price into Korean Won using the conversion rate available to the Offeror on the business day on which the Offer consideration is transferred to the Common Share Depositary, net to the seller in cash without interest thereon, less any required withholding taxes.

      Capitalized terms used and not defined herein shall have the meanings assigned to such terms in the Offer to Purchase.

      The Offer is made pursuant to the Combination Agreement, dated September 12, 2006, by and among the Parent, the Offeror and the Company.

      The information in the Offer to Purchase and the related Letter of Transmittal is incorporated in this Amendment by reference to all of the applicable items in the Initial Statement, except that such information is hereby amended and supplemented to the extent specifically provided herein.

Items 4 and 11. Terms of the Transaction; Additional Information

     Items 4 and 11 are hereby amended and supplemented by adding the following thereto:

     “The Subsequent Offering Period expired at 12:00 midnight, New York City time, on Friday, November 24, 2006. Based on the final count of the depositaries for the tender offer, an aggregate of 2,840,329 common shares and 16,898,820 ADSs, together representing approximately 99.7% of the outstanding common shares and ADSs of the Company, including common shares underlying ADSs, were validly tendered and accepted for payment.

     Pursuant to the Combination Agreement, the Company intends to apply for delisting of the ADSs from the Nasdaq Global Market and for termination of registration of the Common Shares and ADSs under the Exchange Act as soon as the requirements for such delisting and termination are met.”

      After due inquiry and to the best of its knowledge and belief, each of the undersigned certifies that the information set forth in this statement is true, complete and correct.
