Kookmin Bank Finalizes Stock Transfer Ratios

for the Establishment of the Financial Holding Company

Kookmin Bank (the “Bank”) disclosed that its Board of Directors, in a meeting held on April 30, 2008, approved the share transfer plan for the establishment a financial holding company.

Each of the Bank and the Bank’s subsidiaries held a meeting of its board of directors on April 30, 2008 and finalized the stock transfer ratio to be applied to the stock transfer between it and the financial holding company. The stock transfer ratio between the Bank and the financial holding company has been determined as 1:1. As a result, in the stock transfer between the Bank and the financial holding company, each holder of one share of the Bank’s common stock will receive one share of the financial holding company’s common stock.

With respect to stock transfers between the subsidiaries of the Bank and the financial holding company, the stock transfer ratio applicable to each of KB Real Estate Trust Co., Ltd., KB Investment Co., Ltd., KB Credit Information Co., Ltd., KB Data Systems Co., Ltd., KB Asset Management Co., Ltd., KB Futures Co., Ltd. and KB Investment & Securities Co., Ltd. has been determined as 1:0.2292600, 1:0.2157556, 1:0.4372667, 1:0.9163507, 1:0.8417392, 1:01683928 and 1:0.3823499, respectively.

The Bank, which is planning to establish the financial holding company in late September 2008, also determined the Bank’s proposed purchase price for shares of the Bank’s common stock for which appraisal rights are exercised as Won 63,293 per share. Stockholders of the Bank who oppose the stock transfer must dissent in writing to the Bank before the stockholders’ meeting to approve the stock transfer, which will be held in late August 2008, and exercise their appraisal rights during the appraisal right exercise period.

The Bank calculated its proposed purchase price for shares for which appraisal rights are exercised as the arithmetic average of the weighted average daily closing price of the Bank’s common stock for the two month period, one month period and one week period ending immediately prior to April 29, 2008, the date immediately prior to the date of its Board of Directors’ resolution.



The Bank plans to submit the stock transfer plan, as approved by the Bank’s Board of Directors on April 30, 2008, to the Financial Services Commission for regulatory approval of the establishment of the financial holding company.
