      notices referred to in this CLAUSE 3.

3.2   The Pledgor and SLK shall each undertake to take all steps required under
      Korean law to perfect the Pledge, including but not limited to recording
      in the register of shareholders of SLK the existence of the Pledge and

      4.1   The Pledgor has full power and authority to execute and deliver and
            to perform all of its obligations under this Agreement. The
            execution, delivery or performance of this Agreement will not
            violate or constitute a default under any law, rule, regulation,
            order, decree, contract, agreement, or its constitution or
            obligation of, or applicable to, the Pledgor or regarding the
            Shares. This Agreement is a valid and binding obligation of the
            Pledgor, enforceable against the Pledgor in accordance with its
            terms, subject to applicable bankruptcy, reorganisation, insolvency,
            moratorium or similar laws affecting creditors' rights generally.

<PAGE>

      4.2   The Pledgor and SLK shall each execute, acknowledge and deliver or
            cause to be executed, acknowledged and delivered to the Pledgee and
            at any time or times hereinafter at the request of the Pledgee, all
            documents, instruments, letters of direction, notices, reports,
            acceptances, receipts, consents, waivers, affidavits and
            certificates as the Pledgee may reasonably request in writing, in
            form and substance satisfactory to the Pledgee, required under
            Korean laws to perfect and maintain the first priority security
            interest granted by the Pledgor pursuant to this Agreement and in
            order to consummate fully all of the transactions contemplated under
            this Agreement.

      4.3   It will give to the Pledgee such information and evidence and in
            such form as it shall reasonably require for the purpose of the
            discharge of the duties, trusts, powers, authorities and discretions
            vested in it under this Agreement, the Securities Purchase
            Agreement, the Transaction Documents or by operation of law.

      4.4   The Pledgor is the legal and beneficial owner of the Collateral, and
            in the case of after-acquired Collateral, will have at the time the
            Pledgor acquires rights in the Collateral, full, good and marketable
            title to the Collateral, free of all liens and encumbrances, and has
            or will have good, right and lawful authority to assign, transfer
            and pledge such Collateral under this Agreement.

      4.5   Upon completion of the actions described in CLAUSE 3 hereof relating
            to the perfection of the Pledge immediately after the execution of
            this Agreement, this Agreement creates a valid first lien upon and
            perfected security interest in the Collateral, subject to no prior
            security interest, lien, charge or encumbrance, or agreement
            purporting to grant any third party a security interest in the
            Collateral.

      4.6   Upon the Pledgor's failure to materially observe or perform any
            covenant, condition or agreement in this Agreement, the Pledgor
            shall give immediate notice in writing to the Pledgee.

      4.7   The representations, warranties and undertakings set out in this
            CLAUSE 4 are made on the date hereof. The representations and
            warranties shall be materially true and correct upon any exercise of
            Additional Investment Rights.

      4.8   The Shares are fully paid.

      regulations pertaining to it; (c) pay when due all taxes, licenses,
      charges and other impositions on or for it and the Collateral; (d)

      and agreements and take such action and obtain such certificates and
      documents in accordance with all applicable Korean laws, statutes and
      regulations, to perfect, evidence and continue the Pledgee's interest in
      the Collateral; and (f) promptly inform the Pledgee of any proceeds set
      forth in Section 2.1(b) and deliver to the Collateral Agent or, in the
      case of cash proceeds, account for the Pledgee, to be subject to this
      Agreement, all such proceeds; provided, however, that Pledgor agrees to
      promptly deliver by wire transfer of immediately available funds any such
      cash proceeds to one or more accounts specified by the Pledgee.

5.2   Until payment and satisfaction in full of the Obligations, the Pledgor
      shall not, without the prior written consent of the Pledgee permit
      anything to be done that may materially impair, or fail to do anything
      necessary to preserve the value of, the Collateral and will immediately
      notify the Pledgee of any material and actual loss or depreciation in the
      value of the Collateral. In particular, the Pledgor shall promptly inform
      the Pledgee upon any rights or powers becoming exercisable or being
      executed under or in relation to the Collateral and the Pledgor undertakes
      to act in accordance with the reasonable instructions of the Pledgee in
      all material matters in connection with the Collateral.

6.    EVENTS OF DEFAULT; CURE

6.1   The happening of any one or more of the following events shall constitute
      a "DEFAULT" under this Agreement and upon the occurrence of any such
      event, the Pledgee shall have the remedies specified herein:

      (a)   the occurrence of an Event of Default (as defined in the Notes) in
            respect of the Notes;

      (b)   except for delivery of the Share certificates, the failure by the
            Pledgor to perfect the Security in accordance with the provisions of
            CLAUSE 3;

      (c)   a material breach of any representation of, or warranty, by the
            Pledgor made in this Agreement which is materially prejudicial to
            the Collateral Agent or the Holders of the Note; or

      (d)   a failure by the Pledgor to substantially observe or perform any
            other covenant or condition of this Agreement to be observed or
            performed by it.

6.2   In any event of a Default, and if such Default can be cured, the Pledgor
      shall have at least ten (10) Business Days after receipt of a written
      notice from the Pledgee of the occurrence of a Default to cure such
      Default; provided, further, the Pledgor shall have an additional ten (10)
      Business Days, to cure the Default if reasonably required and the Pledgor
      is actively pursuing the cure of such Default in good faith ("CURE
      PERIOD"). Upon the lapse of the Cure Period and the Default has not been
      cured to the reasonable satisfaction of the Pledgee, such event shall be
      deemed a "TERMINATION EVENT."


                                       5
<PAGE>

7.    REMEDIES

      Upon the occurrence and during the continuance of a Termination Event, the
      Pledgee shall have all of the rights, powers and remedies granted to
      secured parties to enforce the Pledge and take possession and ownership of
      the Collateral as permitted under Korean law. In addition, all rights,
      powers and remedies of the Pledgee under this Agreement shall be
      cumulative and not alternative and shall be in addition to all rights,
      powers and remedies given to the Pledgee by virtue of any statute, rule of
      law or any other agreement between the Pledgee and the Pledgor to the
      extent not contrary to Korean laws. Any forbearance, failure or delay by
      the Pledgee in exercising any right, power or remedy under this Agreement
      shall not be deemed to be a waiver of such right, power or remedy, and any
      single or partial exercise of any such right, power or remedy under this
      Agreement shall not preclude the further exercise thereof, and every
      right, power and remedy of the Pledgee shall continue in full force and
      effect until such right, power or remedy is specifically waived by an
      instrument in writing executed by the Pledgee. Upon a Termination Event,
      the Pledgee shall have the right (i) to proceed against any person, firm
      or corporation; (ii) to exhaust any Collateral it may hold at any time;
      (iii) to apply any Collateral first to the repayment of the Obligations;
      or (iv) to pursue any other remedy whatsoever in the Pledgee's power and
      authorized under Korean laws.

8.    SALE OR DISPOSITION OF THE COLLATERAL

8.1   The Pledgor hereby authorizes the Pledgee to take full ownership
      (soyukwon) of the Collateral after compliance with foreign investment
      reporting regulations in Korea and sell in whole or any part thereof in
      any manner, which is permitted under Korean law, upon such terms and
      conditions as the Pledgee deems proper upon occurrence of a Termination
      Event provided, however, the Pledgor shall have the right to exclusively
      negotiate the purchase of the Collateral for a period of thirty (30) days
      prior to any sale or transfer of the Collateral to any third party and any
      sale thereafter to a third party shall be at a price no less than that
      offered by the Pledgor. Upon the exercise of such right, the Pledgee shall
      negotiate in good faith with the Pledgor. For the avoidance of doubt, the
      sale of the Collateral herein shall include, without limitation, all acts
      and things as may be done by the Pledgee to enforce its Security over the
      Collateral. Upon consummation of any such sale, the Pledgee shall have the
      right as the owner of the Collateral. Upon consummation of any such sale,
      the Pledgee may assign, transfer, endorse and deliver to the purchaser or
      purchasers thereof the Collateral, or any portion thereof or any interest
      therein, and each such purchaser shall hold the property sold absolutely
      free from any claim or right on the part of the Pledgor or any other
      person; provided, however, that if the Collateral has not been sold to a
      third party, the Pledgor may re-negotiate for the purchase of the
      Collateral. The Pledgor hereby waives (to the extent permitted by law) all
      rights of redemption, stay and/or appraisal which the Pledgor may have. In
      the event of a sale of the Collateral, or any part thereof, after
      deducting actual costs, fees and expenses incurred in connection with the
      disposition thereof, the Pledgee shall apply the residue of the proceeds
      thereof to the full payment of the Obligations.


                                       6
<PAGE>

8.2   If any consent, approval or authorisation of any state, municipal or other
      governmental department, agency or authority should be necessary to
      effectuate any sale or other disposition of the Collateral, receipt,
      conversion into foreign currency and remittance of the proceeds thereof
      whether within or outside of Korea, the Pledgor shall use reasonable best
      efforts to execute such applications and other instruments as may be
      required in connection with securing any such consent, approval or
      authorisation, and shall otherwise use its reasonable best efforts to
      secure the same. If the execution of the aforementioned applications and
      other instruments become necessary due to a Termination Event, the Pledgor
      shall bear all costs and expenses related to the performance of the
      foregoing. If the execution of the aforementioned applications and other
      instruments become necessary, in the absence of a Termination Event, the
      Pledgee shall bear the costs and expenses related to the performance of
      the foregoing.

9.    TERMINATION AND RELEASE OF THE COLLATERAL

On the date on which all of the Obligations have been fully and completely
discharged to the reasonable satisfaction of the Pledgee, this Agreement shall
be deemed to be immediately terminated without any further liability or
obligation by either party hereto and (i) the Pledgee shall promptly return the
Collateral to the Pledgor (or its designee) and (ii) the Pledgor may cause the
removal of the Pledge in the shareholders' registry of SLK. At the cost of the
Pledgor, the Pledgee shall assist the Pledgor in all reasonable requests to
cause the removal of the Pledge including, but not limited to, execution of any
documents or affidavits required under Korean laws to remove the Pledge.

Notwithstanding anything to the contrary contained herein, if (i) after the
Additional Investment Rights have either been exercised in full or terminated,
the aggregate unpaid principal balance of the Notes shall, at any time, be
indefeasibly reduced to less than $2,000,000 (after giving effect to any
indefeasible repayments and redemptions thereof, and any indefeasible partial
conversions thereof to shares of Common Stock), and (ii) the Pledgee receives
Pledgor's written request therefor 91 or more days after such indefeasible
reduction, then, so long as no Termination Event (and no event or circumstance
that, with the passage of time or the giving of notice, or both, would become a
Termination Event) shall have occurred and then be continuing, this Agreement
and the security interests created hereby shall be terminated immediately, and
all the rights to the Collateral shall revert to the Pledgor.

10.   FURTHER ASSURANCES

The Pledgor agrees that upon a Termination Event, the Pledgor will promptly
provide all assistance reasonably requested by Pledgee to protect any Security
over the Collateral or to enable the Pledgee to exercise and enforce its rights
and remedies hereunder with respect to the Collateral.

11.   BINDING AGREEMENT

      This Agreement shall bind and enure to the benefit of the parties hereto,
      their successors and permitted assigns.

      obligations under this Agreement to any successor Pledgee or Collateral
      Agent with prior notice to but without the consent of the Pledgor.

15.   SEVERABILITY

Any provision of this Agreement that is held to be invalid or unenforceable by
any court of competent jurisdiction shall be so only as to such jurisdiction and

      period, the dispute shall be finally resolved by arbitration in accordance

17.   COUNTERPARTS

This Agreement may be executed in counterparts, each of which shall be an
original but all of which together shall constitute one and the same instrument.

18.   INDEMNIFICATION

The Pledgor shall indemnify the Pledgee, each Buyer (as defined in the

connection with the amendment (if necessitated by any change in law) and
enforcement of this Agreement, including, without limitation, during any workout
in collecting any sum which becomes due to the Pledgee under this Agreement; in
connection with any action for declaratory relief, any counterclaim to any
action or cause of action, or any appeal; in the protection or preservation of
