Merger Decision (Revise)

Overview				NHN Games will be merged with and into Webzen under Korean law, pursuant to which NHN Games will cease to exist and Webzen will be the sole surviving entity.
Purpose of Merger				Through a merger with NHN Games, Webzen is expected to strengthen its online game development capabilities and expand of its online game service to enhance the profitability and value of the corporation..
Stock Exchange Ratio				1.57262712 common shares of Webzen per one NHN Games’ common share.
Exchange Ration calculation formula				Article 176-5 of the Enforcement Decree of the Financial Investment Services and Capital Markets Act of Korea (the “Enforcement Decree”) provides that, in cases of a merger between a “stock-listed corporation” and a “stock-unlisted corporation” (i.e., a private company), the stock exchange ratio shall be determined based upon the market price of the stock-listed corporation. The market price is calculated as lower of (a) the most recent closing price (April 14, 2010) and (b) the average of the following: arithmetic average of 1 month volume weighted average closing price, 1 week volume weighted average closing price, and the most recent closing price (April 14, 2010). For the stock-unlisted corporation, the formula is an average of the “intrinsic value” (the weighted average of “asset value” and “earnings value”) and “relative value” to comparable companies, provided that when relative value is unavailable, the intrinsic value can be used without counting in the relative value (the methods of calculating asset value, earnings value and relative value are to be prescribed by the Financial Services Commission (“FSC”)). In this transaction, the intrinsic value (calculated by the weighted average of asset value and earning value applying 1 to 1.5 ratio) was used. Based on the formula stated above, the appraised price per share of merger corporation is KRW 11,800 and such price per share of merged corporation is KRW 18,557, respectively. Thus the exchange ratio is calculated as 1:1.57262712
