Report to the Korea Stock Exchange

                         RE : REVISED GUIDANCE FOR 2004

     The following statements are current estimates and projections for 2004
reflecting management's judgment and involve a number of risks and uncertainties
that could cause actual results to differ materially from those suggested by
these forward-looking statements. These forward-looking information were based
on various factors and were derived utilizing numerous assumptions. Some of the
assumptions and other important factors that could cause actual results to
differ materially from those in the forward-looking information are identified
below.


1.   REVENUE TARGET FOR 2004: APPROXIMATELY KRW 9.8 TRILLION

     The Company has previously provided guidance for its revenues for the year
2004 at approximately KRW 10.2 trillion. The Company has adjusted its
expectations and now estimates its 2004 revenues to be KRW 9.8 trillion. The
adjustment was caused by the changes in the underlying assumptions for the
previously reported revenue guidance. Such changes were as follows:

o    The Company has adjusted its target with respect to the number of wireless
     subscribers in 2004 (discussed below);

o    The Company has revised its target with respect to the monthly average
     revenue per user ("ARPU") from KRW 46,000 to KRW 44,000 due to the reduced
     interconnection revenues, the contract-based discount plans and the
     relatively low ARPU among certain of the new subscribers compared to the
     existing subscribers given the mature market; and


o    The Company has been adversely affected by the changes in the policies
     regarding network interconnection fees among the telecommunications service
     providers by the Ministry of Information and Communication ("MIC").

     Since the Company's previous report, the MIC has also imposed sanctions on
the Company by suspending the Company from signing with new subscribers for 40
days based on its findings that the Company had provided handset subsidies. Such
sanctions have also led the Company to adjust its revenue guidance for 2004.


2.   SUBSCRIBER TARGET FOR 2004: APPROXIMATELY 18.7 MILLION

     The Company has previously reported that its estimate for the number of new
subscribers for 2004 was 18.8 million. The Company has modified its expectations
and revised its guidance for the number of new subscribers to 18.7 million. The
adjustment of the guidance was caused by the 40-day suspension on attracting new
subscribers described above as well as the Company's policy to improve the
quality of its subscriber base by disconnecting the subscribers who have been
suspended due to delinquent payments.


3.   EBITDA MARGIN TARGET: APPROXIMATELY 42%

     The Company has also adjusted its EBITDA margin target from 47% to 42%
primarily due to the new network interconnection rates set forth by the MIC and
the increased marketing expenses under the new mobile number portability policy.
These factors have led the Company to record an EBITDA margin of 40% during the
first half. The Company believes that the impact of these factors will stabilize
during the second half of 2004 and thus has adjusted the year-end EBITDA margin
target to 42%.

     You should not place undue reliance on forward-looking statements, which
are based on current expectations and speak only as of the date of this report.
The Company is not obligated to publicly release any revisions to
forward-looking statements to reflect events after the date of this report. The
Company provides a detailed discussion of risk factors in periodic SEC filings,
including its Form 20-F, and you are encouraged to review these filings.
