ARTICLE 7-1 CHARACTERISTICS OF SERIES A PREFERRED SHARES

(1)  Voting Rights and Dividend Preferences

     A.   Series A Preferred Shares, among the preferred shares to be issued by
          the Company, shall have voting rights. Series A Preferred Shares shall
          be entitled to an annual per share dividend equal to 30% of the par
          value of the Series A


                                        2



          Preferred Shares, payable when and if declared by the Board and the
          shareholders at a General Meetings of Shareholders of the Company.

     B.   The dividends would be non-cumulative and would be paid prior to
          payment of any dividend with respect to the common shares and the
          Series C Preferred Shares; provided, however, that the dividend
          priority of the Series A Preferred Shares and the Series B Preferred
          Shares shall be the same. In the event that the distributable profits
          of the Company are insufficient to cover the sum of the dividend
          preference amount of the holders of both the Series A Preferred Shares
          and the Series B Preferred Shares ("Dividend Preference Amount"), then
          such distributable profits shall be allocated among the holders of the
          Series A Preferred Share and the Series B Preferred Share on a pro
          rata basis.

     C.   After payment of the preferential dividend to the holders of the
          Preferred Shares, any further dividends would be paid pari passu to
          the holders of the Preferred Shares and common shares on a pro rata
          basis. For purposes of dividends on the common shares issued upon
          conversion of the Series A Preferred Shares, it shall be deemed that
          such common shares were issued at the end of the immediately preceding
          fiscal year of the Company.

(2)  Liquidation Preferences

     A.   Upon liquidation or dissolution of the Company, the holders of Series
          A Preferred Shares shall be entitled to be preferentially paid out of
          the remaining assets of the Company available for distribution to its
          shareholders ("Distributable Assets"), an amount equal to the sum of
          (a) 4,550 Won and (b) any declared but unpaid dividends on the Series
          A Preferred Shares, for each Series A Preferred Share (the "Series A
          Liquidation Preference"); provided, however, that (i) in the event of
          stock split or bonus issuance (each, a "Downward Adjustment Event"),
          each time there is a Downward Adjustment Event, the foregoing price of
          the Series A Preferred Share shall be downwardly adjusted, taking into
          account the number of Series A Preferred Shares increased as a result
          of the Downward Adjustment Event; and (ii) in the event of reverse
          stock split or consolidation (each, an "Upward Adjustment Event"),
          each time there is an Upward Adjustment Event, the foregoing price of
          the Series A Preferred Share shall be upwardly adjusted, taking into
          account the number of Series A Preferred Shares decreased as a result
          of the Upward Adjustment Event

     B.   The liquidation priorities of the Series A Preferred Shares and the
          Series B Preferred Shares shall be the same. In the event that the
          Distributable Assets are insufficient to pay both the Series A
          Liquidation Preference and the Series B Liquidation Preference (as
          defined in Paragraph (2)A of Article 7-2 below), then


                                        3



          the Distributable Assets shall be allocated among the holders of the
          Series A Preferred Shares and the Series B Preferred Shares according
          to the following formulas:

          (a)  For each holder of the Series A Preferred Shares: Distributable
               Assets multiplied by (the Series A Liquidation Preference
               associated with such holder's Series A Preferred Share divided by
               the sum of the aggregate Series A Liquidation Preference and the
               aggregate Series B Liquidation Preference).

          (b)  For each holder of the Series B Preferred Shares: Distributable
               Assets multiplied by (the Series B Liquidation Preference
               associated with such holder's Series B Preferred Share divided by
               the sum of the aggregate Series A Liquidation Preference and the
               aggregate Series B Liquidation Preference).

     C.   After the payment of all preferential amounts required to be paid to
          the holders of the Series A Preferred Shares and the Series B
          Preferred Shares upon the liquidation or dissolution of the Company,
          all of the remaining Distributable Assets shall be distributed ratably
          among the holders of the Company's common stock and the Series C
          Preferred Shares.

(3)  Conversion

     A.   Series A Preferred Shares issued by the Company may be converted into
          the common shares at any time at the conversion rate of one Series A
          Preferred Share to one (1) common share, upon request by each of
          holders of such Series A Preferred Share. Request for such conversion
          may be made at any time from the date of issuance of such Series A
          Preferred Shares. If, however, any reasons for adjustment of the
          conversion rate set forth in Paragraph (3)C below or the conversion
          price, a basis for the calculation of such conversion rate (the
          "Conversion Price"), occurs, such conversion rate or Conversion Price
          shall be adjusted in accordance with the provisions of Paragraph (3)C
          below.

     B.   Notwithstanding the provisions of Paragraph (3)A above, in the event
          of (i) a bona fide, underwritten public offering of shares of common
          stock listed on the KOSDAQ or KSE is made pursuant to a registration
          statement filed with the Financial Supervisory Commission in
          accordance with the Securities and Exchange Act of Korea resulting in
          proceeds to the Company of at least US$10,000,000 (or the equivalent
          in Korean Won, using the exchange rate as of the date that such
          proceeds are actually received by the Company) in the aggregate; or
          the listing of the Company's common stock, or depository receipts


                                        4



          representing such common stock, on the New York Stock Exchange, the
          Nasdaq stock market or any other "national securities exchange" which
          is registered pursuant to Section 6 of the Securities Exchange Act of
          1934, as amended ("Qualified IPO"), or (ii) the holders of a majority
          of the outstanding shares of Series A Preferred Shares provide their
          consent, the Series A Preferred Shares issued by the Company shall be
          automatically converted into common shares at the conversion rate of
          one Series A Preferred Share to one common share. If, however, any
          reasons for adjustment of either the conversion rate or the Conversion
          Price set forth in Paragraph (3)C below, occurs, such conversion rate
          or Conversion Price shall be adjusted in accordance with the relevant
          provisions of Paragraph (3)C below.

     C.   Adjustment to the Conversion Ratio and the Conversion Price

          (a)  In the event that the Company issues any new equity shares or
               equity-related securities without consideration or at a purchase
               price less than 4,550 Won (taking into account stock split, stock
               dividend and other similar event), the conversion ratio of the
               Series A Preferred Shares shall be subject to adjustment on a
               weighted average basis for a purchase price of new equity shares
               or equity-related securities less than the then-effective
               conversion price.

          (b)  The conversion ratio shall also be subject to anti-dilution
               protection for stock splits, stock dividends and similar events.
               The mathematical formula for adjustment on a weighted average
               basis is as follows and is subject to the more detailed textual
               description set forth thereafter:

                          ACP = OCP * (OS + (TNC/OCP))
                                ----------------------
                                    (OS + NS)

               WHERE:

               ACP  = adjusted conversion price

               TNC  = the total consideration received by the Company for the
                      additional common shares issued or sold

               NS   = the number of additional common shares issued or sold

               OCP  = old conversion price


                                        5



               OS   = the number of outstanding common shares immediately before
                      the additional common shares are issued or sold

          (c)  The newly adjusted conversion price shall be the amount equal to
               the price determined by multiplying the old conversion price, by
               a fraction,

               (i)  the numerator of which shall be the number of common shares
                    outstanding immediately prior to such issue, plus the number
                    of common shares which the total consideration received by
                    the Company for the additional common shares issued or sold
                    would purchase at the old conversion price; and

               (ii) the denominator of which shall be the number of outstanding
                    common shares immediately before the additional common
                    shares are issued or sold plus the number of additional
                    common shares issued or sold.

          (d)  Provided that, for the purposes of this Paragraph (3)C, all
               common shares issuable upon conversion of all outstanding
               preferred and outstanding convertible securities or exercise of
               outstanding options shall be deemed to be outstanding.
               Notwithstanding the foregoing, the adjusted conversion price
               shall not be less than the par value of the stock of the Company.

          (e)  For purpose of this Article, any new equity shares or
               equity-related securities as used in this Paragraph (3)C shall
               not include the securities described in Article 10(1)B(i) to
               (vii).

          (f)  No fractional shares shall be issued upon conversion of the
               Series A Preferred Shares. The total number of shares of common
               stock to be issued to each holder of Series A Preferred Shares
               upon such conversion shall be determined on the basis of the
               number of shares of common stock issuable upon conversion of the
               Series A Preferred Shares held by such holder at the time of such
               conversion.

     D.   To the extent permissible under Korean law, upon a Qualified IPO, the
          holders of Series A Preferred Shares shall be entitled to adjust the
          conversion ratio of their Series A Preferred Shares so that upon
          conversion thereof, the number of shares of common stock that such
          holders of the Series A Preferred Shares would be entitled to shall be
          the greater of (i) the number of common shares to be issued upon the


                                        6



          conversion of the Series A Preferred Shares, based on the then current
          conversion ratio and (ii) ( 4,550 Won per share plus interest accrued
          thereon at an annual rate of 4.42% from the Closing Date (as defined
          in the First Amended and Restated Preferred Stock Investors Rights
          Agreement) to the date of the Qualified IPO) divided by the offering
          price of the common stock in connection with such Qualified IPO.

(4)  Redemption.

     A.   The Series A Preferred Shares shall be redeemed by the Company out of
          the funds legally available for such purpose at the election of the
          holders of the Series A Preferred Shares at any time beginning from
          May 8, 2005. The redemption right by the holders of the Series A
          Preferred Shares under this Article shall terminate on the 10th
          anniversary of May 8, 2005.

     B.   The date of receipt of any notice (the "Series A Redemption Notice")
          evidencing a holder's election to redeem its Series A Preferred Shares
          provided pursuant to Paragraph (4)A above shall be the "Series A
          Redemption Notice Date". The Company may, no later than fifteen (15)
          calendar days after receipt of such notice, request that such
          holder(s) tender to the Company such transmittal or related materials
          as it may reasonably request. The Company shall, (i) no later than 90
          days from receipt of notice of redemption from the applicable holder,
          should the Company not timely request any transmittal materials, or
          (ii) within 75 days of receipt of requested transmittal materials from
          the redeeming stockholder (the "Series A Redemption Date"), redeem all
          applicable shares of the Series A Preferred Shares (such redeemed
          shares being referred to as the "Series A Redemption Shares"), by
          paying in cash, out of funds legally available therefor, an amount
          equivalent to 5,180 Won for each Series A Preferred Share (the "Series
          A Redemption Price"); provided, however, that (i) each time there is a
          Downward Adjustment Event, the Series A Redemption Price of the Series
          A Preferred Shares shall be downwardly adjusted, taking into account
          the number of Series A Preferred Shares increased as a result of the
          Downward Adjustment Event; and (ii) each time there is an Upward
          Adjustment Event, the Series A Redemption Price of the Series A
          Preferred Shares shall be upwardly adjusted, taking into account the
          number of Series A Preferred Shares decreased as a result of the
          Upward Adjustment Event.

     C.   If the holders of the Series A Preferred Shares make an election to
          redeem their Series A Preferred Shares pursuant to the above
          provisions, each holder of the Series A Preferred Shares shall
          surrender its certificates representing the applicable Series A
          Redemption Shares to the Company together with the Series A Redemption
          Notice. From and after the Series A Redemption Date and the


                                        7



          holders' receipt of the Series A Redemption Price, all rights of each
          holder with respect to such applicable Series A Redemption Shares
          shall cease and such Series A Preferred Shares shall not be deemed to
          be outstanding for any purpose whatsoever. Such holder's election to
          redeem the Series A Preferred Share may not be revoked without the
          written consent of the Company so long as the Company satisfies the
          redemption preference in full within the time period set forth in this
          Article 7-1 (4).

     D.   For the purpose of determining whether funds are legally available for
          redemption of shares of the Series A Preferred Shares as provided
          herein, the Company shall value its assets in accordance with the
          generally accepted accounting practice of Korea. The redemption
          obligation provided herein shall be continuous, so that, if on a
          Series A Redemption Date such obligation shall not be fully
          discharged, without further action by any holder of the Series A
          Preferred Shares, funds legally available shall be applied therefor
          until such obligation are fully discharged. The Series A Preferred
          Shares requested to be redeemed but not so redeemed as a result of
          insufficient legally available funds shall remain outstanding and
          entitled to all rights and preferences provided herein until the
          Series A Redemption Price for such shares is fully paid.

     E.   In the event that the Company does not have sufficient dividendable
          profits to satisfy the requests of redemption submitted by holders of
          the Series A Preferred Shares, the Series B Preferred Shares and the
          Series C Preferred Shares, then the dividendable profits shall be
          allocated among the holders of the Series A Preferred Shares, the
          Series B Preferred Shares and the Series C Preferred Shares according
          to the following formulas:

          (a)  For each holder of the Series A Preferred Shares: such
               dividendable profits multiplied by (the aggregate redemption
               amount associated with such Holder's Series A Preferred Shares
               under subparagraph 7-1(4)B divided by the sum of the redemption
               amounts payable to the holders of the Series A Preferred Shares,
               the Series B Preferred Shares and the Series C Preferred Shares,
               in the aggregate, pursuant to subparagraphs 7-1(4)B, 7-2(4)B and
               7-3(4)B);

          (b)  For each holder of the Series B Preferred Shares: such
               dividendable profits multiplied by (the aggregate redemption
               amount associated with such Holder's Series B Preferred Stock
               under subparagraph 7-2(4)B divided by the sum of the redemption
               amounts payable to the holders of the Series A Preferred Shares,
               the Series B Preferred Shares and the Series C Preferred Shares,
               in the aggregate, pursuant to subparagraphs 7-1(4)B, 7-2(4)B and
               7-3(4)B); and

          (c)  For each holder of the Series C Preferred Shares: such
               dividendable profits multiplied by (the aggregate redemption
               amount associated with such Holder's


                                        8



               Series C Preferred Stock under subparagraph 7-3(4)B divided by
               the sum of the redemption amounts payable to the holders of the
               Series A Preferred Shares, the Series B Preferred Shares and the
               Series C Preferred Shares, in the aggregate, pursuant to
               subparagraphs 7-1(4)B, 7-2(4)B and 7-3(4)B).

          Provided, however, that, when the Company receives a Series C
          Redemption Notice (as defined in subparagraph 7-3(4)B) from a holder
          of the Series C Preferred Shares, if (i) the Company have not received
          any Series A Redemption Notice and Series B Redemption Notice (as
          defined in subparagraph 7-2(4)B), or (ii) the redemption amounts
          payable to a holder of the Series A Preferred Shares or the Series B
          Preferred Shares, as the case may be, have been fully paid pursuant to
          a Series A Redemption Notice or a Series B Redemption Notice the
          Company have received prior to the Series C Redemption Notice, the
          redemption amounts payable to the holder of the Series C Preferred
          Shares shall be paid with priority over payment of redemption amounts
          to any holder of the Series A Preferred Shares and the Series B
          Preferred Shares.

     F.   To the extent legally permitted and so long as such redemption
          election occurs on or after October 8, 2007, PIK interest shall accrue
          on any amount that the Company fails to redeem under this Article 7-1
          (4) or (5) pursuant to the procedures set forth in the Article 7-1(4)
          B at a rate equal to twice the United States prime rate, as published
          by the Wall Street Journal on the date of the notice of redemption.

     G.   Notwithstanding any contrary provision, the holders of Series A
          Preferred Shares and the holders of Series B Preferred Shares may not
          exercise their redemption rights unless the number of issued and
          outstanding Series C Preferred Shares is below 500,000 shares.

(5)  Redemption upon Sale

     A.   In the event of a Sale (as defined below), the holders of Series A
          Preferred Shares shall be entitled to cause the Company to redeem the
          Series A Preferred Shares at the greater of (i) 4,550 Won per share
          plus the amount calculated by annual rate of 4.42% from the Closing
          Date (as defined in the First Amended and Restated Preferred Stock
          Investors Rights Agreement) to the date of redemption; provided,
          however, that (A) each time there is a Downward Adjustment Event, the
          foregoing price of the Series A Preferred Shares shall be downwardly
          adjusted, taking into account the number of shares of Series A
          Preferred Shares increased as a result of the Downward Adjustment
          Event; and (B) each time there is an Upward Adjustment Event, the
          foregoing price of the Series A Preferred Shares shall be


                                        9



          upwardly adjusted, taking into account the number of shares of Series
          A Preferred Shares decreased as a result of the Upward Adjustment
          Event, or (ii) what such holder would have received in connection with
          the Sale assuming conversion of the Series A Preferred Shares at the
          then applicable conversion ratio.

          A "Sale" shall mean (i) a sale of all or substantially all assets of
          the Company, (ii) a change of control of the Company, or (iii) merger
          or consolidation of the Company where the Company is not the surviving

          the Korean Fair Trade Commission from time to time); provided,
          however, the affiliate transferees agree to execute relevant documents
          and be bound by the terms and conditions applicable to the transferor
          under the First Amended and Restated Preferred Stock Investors Rights
          Agreement.

               amount associated with such Holder's Series B Preferred Stock
               under subparagraph 7-2(5)B divided by the sum of the redemption
               amounts payable to the holders of the Series A Preferred Stock
               and the Series B Preferred Stock, in the aggregate, pursuant to
               subparagraphs 7-1(5)A and 7-2(5)B)

          Preferred Shares except for the payment or distributions to the
          holders of the Series C Preferred Shares in

ARTICLE 7-2 CHARACTERISTICS OF SERIES B PREFERRED SHARES

(1)  Voting Rights and Dividend Preferences

     A.   The Series B Preferred Shares, among the preferred shares to be issued
          by the Company, shall have voting rights. The Series B Preferred
          Shares shall be entitled to an annual per share dividend equal to 30%
          of the par value of the Series B Preferred Shares, payable when and if
          declared by the Board and the shareholders at a General Meeting of
          Shareholders of the Company.

     B.   The dividends would be non-cumulative and would be paid prior to
          payment of any dividend with respect to the common shares and the
          Series C Preferred Shares; provided, however, that the dividend
          priority of the Series A Preferred Shares and the Series B Preferred
          Shares shall be the same. In the event that the distributable profits
          of the Company are insufficient to cover the Dividend Preference
          Amount, then such distributable profits shall be allocated among the
          holders of the Series A Preferred Share and the Series B Preferred
          Share on a pro rata basis.

     C.   After payment of the preferential dividend to the holders of the
          Preferred Shares, any further dividends would be paid pari passu to
          the holders of the Preferred Shares and common shares on a pro rata
          basis. For purposes of dividends on the common shares issued upon
          conversion of the Series B Preferred Shares, it shall be deemed that
          such common shares were issued at the end of the immediately preceding
          fiscal year of the Company.

(2)  Liquidation Preferences

     A.   Upon liquidation or dissolution of the Company, the holders of Series
          B Preferred Shares shall be entitled to be preferentially paid an
          amount equal to the greater of (i) 13,985.5472 Won multiplied by the
          number of Series B Preferred Share owned by such holder of Series B
          Preferred Share plus any declared but unpaid dividends on the Series B
          Preferred Share (the "Series B Liquidation Preference") or (ii) what
          such holder would have received at the time of such liquidation or
          dissolution assuming conversion of the Series B Preferred Share at


                                       11



          the then applicable conversion ratio, pari passu, out of the assets or
          surplus funds of the Company available for distribution to its
          shareholders ("Distributable Assets") before any payment shall be made
          to the holders of the common shares and the Series C Preferred Shares
          by reason of their ownership thereof; provided, however, that (i) each
          time there is a Downward Adjustment Event, the foregoing price of the
          Series B Preferred Shares shall be downwardly adjusted, taking into
          account the number of Series B Preferred Shares increased as a result
          of the Downward Adjustment Event; and (ii) each time there is an
          Upward Adjustment Event, the foregoing price of the Series B Preferred
          Shares shall be upwardly adjusted, taking into account the number of
          Series B Preferred Shares decreased as a result of the Upward
          Adjustment Event.

     B.   The liquidation priority of the Series A Preferred Shares and the
          Series B Preferred Shares shall be pari passu. In the event that the
          Distributable Assets are insufficient to pay both the Series A
          Liquidation Preference and the Series B Liquidation Preference, then
          the Distributable Assets shall be allocated in accordance with the
          provisions of Paragraph (2)B of Article 7-1.

     C.   After the payment of all preferential amounts required to be paid to
          the holders of the Series A Preferred Shares and the Series B
          Preferred Shares upon the liquidation or dissolution of the Company,
          all of the remaining Distributable Assets shall be distributed ratably
          among the holders of the Company's common stock and the Series C
          Preferred Shares.

(3)  Conversion.

     A.   The Series B Preferred Shares issued by the Company may be converted
          into the common shares at any time at the conversion rate of one
          Series B Preferred Share to one (1) common share, upon request by each
          of holders of such Series B Preferred Shares. Request for such
          conversion may be made at any time from the date of issuance of such
          Series B Preferred Shares; provided, however, that the provisions of
          Paragraph (3)C of Article 7-1 shall apply mutatis mutandis to the
          adjustment of the conversion ratio or the conversion price of the
          Series B Preferred Shares.

     B.   Notwithstanding the provisions of Paragraph (3)A above, in the event
          (i) of the completion of a Qualified IPO, or (ii) the holders of a
          majority of the outstanding shares of Series B Preferred Shares
          provide their consent, the Series B Preferred Shares issued by the
          Company shall be automatically converted into common shares at the
          conversion rate of one Series B Preferred Share to one common share;
          provided, however, that that the provisions of Paragraph (3)C of
          Article 7-1 shall apply mutatis mutandis to the adjustment of the
          conversion ratio or the


                                       12



          conversion price of the Series B Preferred Shares.

     C.   To the extent permissible under Korean law upon a Qualified IPO, the
          conversion ratio of the Series B Preferred Share shall automatically
          adjust so that the number of common shares into which each Series B
          Preferred Share may convert shall be the greater of (i) the number of
          common shares into which each Series B Preferred Share may convert
          prior to such adjustment, and (ii) 10,349.3049 Won plus interest
          accrued thereon at an annual rate of 4.42% from the date of issuance
          of such Series B Preferred Shares to the date of the Qualified IPO)
          divided by the offering price per share of the common shares upon such
          Qualified IPO.

(4)  Redemption.

     A.   The Series B Preferred Shares shall be redeemed by the Company out of
          the funds legally available for such purpose at the election of each
          of the holders of the Series B Preferred Shares at any time beginning
          from the earlier of (i) October 8, 2007 or (ii) the date upon which
          any shares of the Series A Preferred Shares are redeemed. The
          redemption right by the holders of the Series B Preferred Shares under
          this Article shall terminate 10 years from the date of issuance of the
          Series B Preferred Shares ("Redemption Deadline").

     B.   The date of receipt of any notice (the "Series B Redemption Notice")
          evidencing a holder's election to redeem its Series B Preferred Shares
          provided pursuant to Paragraph (4)A above shall be the "Series B
          Redemption Notice Date". The Company may, no later than fifteen (15)
          calendar days after receipt of such notice, request that such
          holder(s) tender to the Company such transmittal or related materials
          as it may reasonably request. The Company shall, (i) no later than 90
          days from receipt of notice of redemption from the applicable holder,
          should the Company not timely request any transmittal materials, or
          (ii) within 75 days of receipt of requested transmittal materials from
          the redeeming stockholder (the "Series B Redemption Date"), redeem all
          applicable shares of the Series B Preferred Shares (such redeemed
          shares being referred to as the "Series B Redemption Shares"), by
          paying in cash, out of funds legally available therefor, an amount set
          forth below:

          (a)  If the Series B Preferred Shares are redeemed on or prior to
               October 8, 2007, such Series B Preferred Shares shall be redeemed
               by the Company at a price of 5,180 Won per share; provided,
               however, that (i) each time there is a Downward Adjustment Event,
               the foregoing price of the Series B Preferred Shares shall be
               downwardly adjusted, taking into account the number of shares of
               Series B Preferred Shares increased as a result of the Downward


                                       13



               Adjustment Event; (ii) each time there is an Upward Adjustment
               Event, the foregoing price of the Series B Preferred Shares shall
               be upwardly adjusted, taking into account the number of shares of
               Series B Preferred Shares decreased as a result of the Upward
               Adjustment Event and (iii) if less than one hundred percent
               (100%) of the Series A Preferred Shares is being redeemed, the
               Company shall be required to redeem only the same percentage of
               Series B Preferred Shares, with each holder of the Series B
               Preferred Shares able to redeem a number of shares equal to such
               percentage of the total number of shares of the Series B
               Preferred Shares. For the avoidance of doubt, no interest shall
               accrue under sub-paragraph (4)B(b) of this Article 7-2 below on
               any amount redeemed on or prior to the October 8, 2007.

          (b)  If the Series B Preferred Share is redeemed after October 8,
               2007, such Series B Preferred Share shall be redeemed by the
               Company at a price of 11,781.4249 Won per share; provided,
               however, that (i) each time there is a Downward Adjustment Event,
               the Series B Redemption Price of the Series B Preferred Shares
               shall be downwardly adjusted, taking into account the number of
               shares of Series B Preferred Shares increased as a result of the
               Downward Adjustment Event; and (ii) each time there is an Upward
               Adjustment Event, the Series B Redemption Price of the Series B
               Preferred Shares shall be upwardly adjusted, taking into account
               the number of shares of Series B Preferred Shares decreased as a
               result of the Upward Adjustment Event.

          (c)  If the Series B Preferred Shares are redeemed after October 8,
               2007 ("Third Anniversary Redemption Date"), each holder of Series
               B Preferred Shares shall be entitled to redeem one-third (1/3) of
               the Series B Preferred Share (together with any accrued interest
               thereon pursuant to sub-paragraph (4)B(d) below, held by such
               holder of the Series B Preferred Shares as of the date of
               issuance of such Series B Preferred Shares, during each
               twelve-month period following the Third Anniversary Redemption
               Date up to the Redemption Deadline.

          (d)  Payment-in-kind, or "PIK" interest shall accrue at an annual rate
               of 4.42% on two-thirds (2/3) (no interest shall accrue on the
               remaining one-third (1/3) Series B Redemption Price) of the
               Series B Redemption Price (together with any interest accrued
               thereon, the "2/3 Redemption Price") beginning on the Third
               Anniversary Redemption Date and ending on the first anniversary
               thereof ("Fourth Anniversary Redemption Date"). Interest on
               one-half (1/2) of the 2/3 Redemption Price shall accrue at an
               annual rate of 4.42% beginning on the date following the Fourth
               Anniversary Redemption


                                       14



               Date and ending on the first anniversary thereof. No interest
               shall accrue on any Series B Redemption Price after the second
               anniversary of the Third Anniversary Redemption Date.

     C.   To the extent legally permitted and so long as such redemption
          election occurs on or after October 8, 2007, PIK interest shall accrue
          on any amount that the Company fails to redeem under this Article 7-2
          (4) or (5) pursuant to the procedure set forth in the Article 7-2 (4)B
          at a rate equal to twice the United States prime rate, as published by
          the Wall Street Journal on the date of the notice of redemption

     D.   If the holders of the Series B Preferred Shares make an election to
          redeem their Series B Preferred Shares pursuant to the above
          provisions, each holder of the Series B Preferred Shares shall
          surrender its certificates representing the applicable Series B
          Redemption Shares to the Company together with the Series B Redemption
          Notice. From and after the Series B Redemption Date and the date of
          the holders' receipt of the full Series B Redemption Price, all rights
          of each holder with respect to such applicable Series B Redemption
          Shares shall cease and such Series B Preferred Shares shall not be
          deemed to be outstanding for any purpose whatsoever. Such holder's
          election to redeem the Series B Preferred Share may not be revoked
          without the written consent of the Company so long as the Company
          satisfies the redemption preference in full within the time period set
          forth in this Article 7-2 (4).

     E.   For the purpose of determining whether funds are legally available for
          redemption of shares of the Series B Preferred Shares as provided
          herein, the Company shall value its assets in accordance with the
          generally accepted accounting practice of Korea. The redemption
          obligation provided herein shall be continuous, so that, if on a
          Series B Redemption Date such obligation shall not be fully
          discharged, without further action by any holder of the Series B
          Preferred Shares, funds legally available shall be applied therefor
          until such obligation are fully discharged. The Series B Preferred
          Shares requested to be redeemed but not so redeemed as a result of
          insufficient legally available funds shall remain outstanding and
          entitled to all rights and preferences provided herein until the
          redemption price set forth in Paragraph (4)(B)(a) of this Article 7-2
          or the Series B Redemption Price, as the case may be, for such shares
          is fully paid.

     F.   In the event that the Company does not have sufficient dividendable
          profits to satisfy the requests of redemption submitted by holders of
          the Series A Preferred Shares, the Series B Preferred Shares and the
          Series C Preferred Shares, then the dividendable profits shall be
          allocated in accordance with the provisions of Paragraph (4)E of
          Article 7-1.

     G.   Notwithstanding any contrary provision, the holders of Series A
          Preferred Shares and the holders of Series B Preferred Shares may not
          exercise their redemption rights unless the number of issued and
          outstanding Series C Preferred Shares is below 500,000 shares.


                                       15



(5)  Redemption upon Sale

     A.   To the extent permissible under Korean law, the holders of Series B
          Preferred Share shall be entitled to cause the Company to redeem until
          the Redemption Deadline the Series B Preferred Share in the event of a
          Sale (as defined Article 7-1 (5) A).

     B.   If the Series B Preferred Shares are redeemed upon a Sale, each Series
          B Preferred Share shall be redeemed by the Company at the greater of
          (i) 10,349.3049 Won plus the amount calculated by annual rate of 4.42%
          from the date of issuance of such Series B Preferred Share to the date
          of redemption; provided, however, that (A) each time there is a
          Downward Adjustment Event, the foregoing price of the Series B
          Preferred Share shall be downwardly adjusted, taking into account the
          number of shares of Series B Preferred Share increased as a result of
          the Downward Adjustment Event; and (B) each time there is an Upward
          Adjustment Event, the foregoing price of the Series B Preferred Share
          shall be upwardly adjusted, taking into account the number of shares
          of Series B Preferred Share decreased as a result of the Upward
          Adjustment Event, or (ii) what such holder would have received in
          connection with the Sale assuming conversion of the Series B Preferred
          Share at the then applicable conversion ratio.

     C.   Subparagraph 7-1(5)B shall be applied in the event that the Company
          does not have sufficient dividendable profits available for
          distribution in accordance with applicable law to pay the redemption
          amount set forth in subparagraphs 7-1(5)A and 7-2(5)B.

     D.   With regard to the redemption upon Sale, the provisions of Article
          7-2(4)B, C, D and E shall be applied mutatis mutandis.

          notice of redemption from the applicable holder, should the Company
          not timely request any transmittal materials, or (ii) within 30 days
          of receipt of requested transmittal materials from the redeeming
          stockholder (the "Series C Redemption Date"), redeem all applicable
          shares of the Series C Preferred Shares (such redeemed shares being
          referred to as the "Series C Redemption Shares"), by paying in cash,
          out of funds legally available therefor, an amount set forth below

               redeemed by the Company at the issuance price per share of the
               Series C Preferred Shares (the "Series C Issuing Price") plus an
               amount at an annual rate of 10% of the Series C Issuing Price
               beginning on the issuance date and ending on the Series C
               Redemption Date per share; provided, however, that (i) each time
               there is a Downward Adjustment Event, the foregoing price of the
               Series C Preferred Shares shall be downwardly adjusted, taking
               into account the number of shares of Series C Preferred Shares
               increased as a result of the Downward Adjustment Event; (ii) each
               time there is an Upward Adjustment Event, the foregoing price of
               the Series C Preferred Shares shall be upwardly adjusted, taking
               into account the number of shares of Series C Preferred Shares
               decreased as a result of the Upward Adjustment Event.

          (b)  If the Series C Preferred Share is redeemed after December 31,
               2006, such Series C Preferred Share shall be redeemed by the
               Company at 115% of the Series C Issuing Price per share;
               provided, however, that (i) each time there is a Downward
               Adjustment Event, the foregoing price of the Series C Preferred
               Shares shall be downwardly adjusted, taking into account the
               number of shares of Series C Preferred Shares increased as a
               result of the Downward Adjustment Event; (ii) each time there is
               an Upward Adjustment Event, the foregoing price of the Series C
               Preferred Shares shall be upwardly adjusted, taking into account
               the number of shares of Series C Preferred Shares decreased as a
               result of the Upward Adjustment Event.

          (c)  Notwithstanding (a) and (b) above, the redemption price of the
               Series C Preferred Shares may be reduced by an agreement of the
               Company and each holder of the Series C Preferred Shares
               exercising its redemption right under this Article 7-3(4).


                                       18

          surrender its certificates representing the applicable Series C
          Redemption Shares to the Company together with the Series C Redemption
          Notice. From and after the Series C Redemption Date and the date of
          the holders' receipt of the full Series C Redemption Price, all rights
          of each holder with respect to such applicable Series C Redemption
          Shares shall cease and such Series C Preferred Shares shall not be
          deemed to be outstanding for any purpose whatsoever. Such holder's
          election to redeem the Series C Preferred Share may not be revoked
          without the written consent of the Company so long as the Company
          satisfies the redemption preference in full within the time period set
          forth in this Article 7-3 (4).

     D.   For the purpose of determining whether funds are legally available for
          redemption of shares of the Series C Preferred Shares as provided
          herein, the Company shall value its assets in accordance with the
          generally accepted accounting practice of Korea. The Series C
          Preferred Shares requested to be redeemed but not so redeemed as a
          result of insufficient legally available funds shall remain
          outstanding and entitled to all rights and preferences provided herein
          until the Series C Redemption Price for such shares is fully paid or
          until December 1, 2007, whichever is earlier.

     E.   In the event that the Company does not have sufficient dividendable
          profits to satisfy the requests of redemption submitted by holders of
          the Series A Preferred Shares, the Series B Preferred Shares and the
          Series C Preferred Shares, then the dividendable profits shall be
