      disclosure. For the purpose of the foregoing exceptions, disclosures which
      are specific as to engineering and design practices and techniques,
      products, software, operating parameters and know-how shall not be deemed
      to be within the foregoing exceptions merely because they are embraced by
      general disclosures which are in the public domain or in the possession of
      the receiving party. In addition, any combination of features shall not be
      deemed to be within the

      foregoing exceptions merely because individual features thereof are in the
      public domain or in the possession of the receiving party, but only if the
      combination itself and its principle of operation are in the public domain
      or in the possession of the receiving party. When Confidential Information
      is disclosed in written or other tangible form, it shall be clearly marked
      with a legend identifying it as confidential. Also, if disclosed in oral

      confidential in accordance with the terms of the applicable Services
      Schedule.

2.    DEVELOPMENT

2.1.  Services Schedule. In the event that the parties hereto shall reach
      agreement with respect to a particular Port, a Services Schedule for said
      Port shall be attached to this Agreement and the two shall collectively,
      independent from other Services Schedules, constitute the entire agreement
      for the specific Port. No Services Schedule shall be attached to this
      Agreement without first being executed by the parties hereto. To the
      extent that any terms set forth in a Services Schedule shall conflict with
      the terms set forth in this Agreement, the terms of this Agreement shall
      control unless otherwise specifically set forth in the Services Schedule.

2.2   Services. HSNS hereby agrees to provide the Services for Samsung, as set
      forth in each Services Schedule attached hereto.

2.3   Porting Team. HSNS shall provide the facilities and assign personnel to
      each Porting Team under a Services Schedule. Samsung shall provide the
      development tools and, to the extent requested or required by HSNS,
      personnel to the Porting Team under a Services Schedule.

            (20) business days after Samsung's receipt of the beta version of
            the Deliverables and thirty (30) days after receipt of the final
            version of the Deliverables. Acceptance shall be in writing, and
            Samsung shall not unreasonably withhold its acceptance. If Samsung
            identifies Errors in any Deliverable prior to acceptance, then the
            applicable Porting Team shall correct such Errors within fourteen
            (14) days


                      HSNS Confidential & Proprietary               Page 3 of 15
<PAGE>
            following receipt of notice thereof during acceptance testing for
            the particular Deliverable and within the time specified in Exhibit
            A with respect to Errors discovered after acceptance testing for the
            Deliverables.

      2.4.2 For documentation or report Deliverables under any Services
            Schedule, Samsung shall evaluate each version of such Deliverable.
            In the event that it requires corrections, Samsung shall specify the
            corrections needed and the applicable Porting Team shall deliver an
            amended version of such documentation within five (5) business days.

      2.4.3 If the applicable Porting Team fails to deliver any Deliverable
            within the dates specified in the applicable Services Schedule and
            if any Errors discovered before acceptance cannot be eliminated in
            the correction period specified in Sections 2.4.1 and 2.4.2 above,
            then Samsung may, at its option: (i) extend the correction period or
            (ii) suspend its performance and/or terminate such Services Schedule
            for cause pursuant to Section 8.3, provided, however, that Samsung
            need not provide HSNS the cure period specified in Section 8.3.

2.5   Design Review and Specifications Changes. HSNS understands that there may
      be additions, deletions or other changes that may affect the Requirements
      at any time during the term of this Agreement. In the event that HSNS is
      requested by Samsung or required to perform services beyond those, which
      are specifically set forth in a Services Schedule, any such additional
      services and a compensation schedule therefor shall be mutually agreed
      upon by the parties in writing prior to the provision of said services.
      Said mutually agreed upon writing shall be an amendment to the pertinent
      Services Schedule and appended thereto, and the services set forth therein
      shall be deemed to be Services as the term is used in this Agreement.

3.    PAYMENT FOR SERVICES

3.1   Payments. Except as otherwise expressly provided in a payment schedule
      attached to an applicable Services Schedule, HSNS shall submit to Samsung
      an invoice, on a monthly basis, describing the Services performed in
      connection with each Port, individually, and, where applicable, costs
      incurred, for each preceding month, and Samsung shall pay each such
      invoice within thirty (30) days of receipt.

3.2   Payment upon Termination. In the event any Services Schedule, or this
      Agreement, is terminated by Samsung pursuant to Section 8 of this
      Agreement, including a termination under Section 2.4.3 above, HSNS shall
      be compensated for all fees and costs incurred for actual work performed
      under each terminated Services Schedule(s) prior to the date HSNS receives
      notice of such termination. Additionally, HSNS shall be reimbursed for any
      and all non-cancelable third party obligations related to such terminated
      Services Schedule(s) that are incurred prior to HSNS's receipt of notice
      of such termination, provided that HSNS shall use its best efforts to
      mitigate same. Any funds paid by Samsung to HSNS, which shall be shown by
      Samsung to be unearned at the date of termination shall be returned to
      Samsung within thirty (30) days of any Services Schedule termination.
      Certain Services of HSNS may require greater


                      HSNS Confidential & Proprietary               Page 4 of 15
<PAGE>
      utilization of resources at the outset such that compensation based on a
      percentage of the Services completed prior to HSNS completing the full
      Services set forth in a Services Schedule would work to the detriment of
      HSNS. Accordingly, the parties agree that in the event of early
      termination by Samsung, compensation for partially completed Services
      shall be made on a time and materials basis.

4.    OWNERSHIP RIGHTS

4.1   HSNS.

      4.1.1 HSNS shall own all right, title, and interest in and to all HSNS

            any United States or foreign patents or copyright registrations

            Samsung Technology, Samsung Confidential Information, the Products,

            of the foregoing, by whomever made, and all intellectual property
            rights related thereto. In the event that any HSNS personnel make a
            contribution to the Samsung Technology, Samsung Confidential
            Information, the Products, or any Derivative Technology created
            from, based on, or related to any of the foregoing, including,
            without limitation, all rights in and to any inventions and designs

            copyrights, patents or other intellectual property rights relating
            thereto, in any and all countries, and to execute all documents
            reasonably necessary for Samsung to do so.

      4.2.3 HSNS agrees that if Samsung is unable, because of HSNS's
            unavailability, dissolution, or for any other reason, to secure any

            United States or foreign patents or copyright registrations covering

            documentation and materials.

      4.3.3 Samsung agrees that it and its employees, consultants, agents and
            representatives will not directly or indirectly (i) disassemble,
            decompile or otherwise reverse engineer any Deliverable or otherwise

sublicense, or distribute for itself, or have others acquire, develop, import,
manufacture, market, sell, license, sublicense, or distribute for HSNS, the

      6.2   Samsung's Confidential Information. HSNS shall protect Samsung's

            care. HSNS will not use Samsung's Confidential Information for
            purposes other than those necessary to directly further the purposes
            of this Agreement. For a period of five (5) years, HSNS will not
            disclose to third parties Samsung's Confidential Information without

      this Agreement in accordance with its terms.

9.    LIMITATION OF LIABILITY

EXCEPT FOR BREACHES OF SECTIONS 4, 6, 7.1, AND 7.2 HEREUNDER, NEITHER PARTY
SHALL BE LIABLE UNDER ANY CONTRACT, NEGLIGENCE, STRICT LIABILITY OR OTHER THEORY
FOR ANY INDIRECT, INCIDENTAL, PUNITIVE, SPECIAL, OR CONSEQUENTIAL DAMAGES,
INCLUDING, WITHOUT LIMITATION, LOSS OF BUSINESS, REVENUE, PROFITS, USE, DATA, OR
OTHER ECONOMIC ADVANTAGE, WITH RESPECT TO ANY SUBJECT MATTER OF THIS AGREEMENT,
EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

10.   ARBITRATION

10.1  Procedure. The parties shall make diligent and reasonable efforts to
      amicably settle all disputes, controversies, or differences, which may
      arise between the parties hereto, out of or in relation to or in
      connection with this Agreement. Upon the occurrence of a dispute between
      the parties, including, without limitation, any breach of this Agreement
      or any obligation relating thereto, the matter shall be referred first to
      the managers of HSNS and Samsung having responsibility for the subject
      matter of the dispute, or their designees. The managers, or their
      designees, as the case may be, shall negotiate in good faith to resolve
      such dispute in a mutually satisfactory manner for thirty days. If such
      efforts do not result in mutually satisfactory resolution of the dispute,
      the matter shall be referred to the chief executive officer of each party,
      or their respective designees. The chief executive officers, or their
      designees, as the case may be, shall negotiate in good faith to resolve
      such dispute in a mutually satisfactory manner for thirty days, or such
      longer period of time to which the chief executive officers may agree. If
      such efforts do not result in a mutually satisfactory resolution, the
      dispute shall be finally settled by arbitration in New York, New York in
      accordance with the then-current Commercial Rules


                      HSNS Confidential & Proprietary               Page 9 of 15
<PAGE>
      of Arbitration of the American Arbitration Association, and the award of
      the arbitration shall be final and binding on both parties. The parties
      shall use their best efforts to mutually agree upon one arbitrator
      provided, however, that if the parties have not done so within ten days
      after initiation of arbitration hereunder, or such longer period of time
      as the parties have agreed to in writing, then there shall be three
      arbitrators, including one nominee of HSNS, one nominee of Samsung, and a
      third person selected by said nominees. Judgment upon the award rendered
      may be entered in the highest court or forum, state or federal, having
      jurisdiction; provided, however, that the provisions of this Section 10
      shall not apply to any dispute or controversy as to which any treaty or
      law prohibits such arbitration. The prevailing party shall be entitled to
      reasonable attorneys' fees and costs to be fixed by the arbitrators. At
      least one arbitrator shall be an attorney with expertise in intellectual
      property law and practice and the software arts.

10.2  Injunctive Relief. Notwithstanding the above, pending the outcome of any
      arbitration proceedings, in the event that either party is in breach of,
      or threatens to breach, any obligation of confidentiality hereunder, the
      non-breaching party shall be entitled to apply to any court having
      jurisdiction over the breaching party seeking injunctive relief (interim,
      interlocutory, and/or final) to prevent the breaching party from breaching
      or continuing to breach any such obligation.

11.2  Independent Contractors. Samsung and HSNS are independent contractors as
      to each other, and at no time shall either be deemed to be or hold itself
      out as the agent, partner or representative of the other. Nothing in this
      Agreement shall be construed to form a joint venture or partnership
      between the parties.


11.3  Press Releases. The parties will cooperate with each other on press
      releases and similar communications regarding the non-confidential subject
      matter of this Agreement. The content, timing and necessity of any and all
      press releases or similar communications will be agreed upon in writing by
      both parties prior to any such release or communication.

11.4  Taxes. In the event taxes are required to be withheld on payments made
      under this Agreement by any U.S. (state or federal) or foreign government,
      Samsung may deduct such taxes from the amount owed HSNS and pay them to
      the appropriate taxing authority. Samsung shall in turn promptly secure
      and deliver to HSNS an official receipt for any taxes withheld. Samsung
      will use reasonable efforts to minimize such taxes to the extent permitted
      under applicable law. Additionally, Samsung shall promptly provide HSNS
      with copies of tax certificates showing that such tax payments have been
      made by Samsung. Under the Convention for the Avoidance of Double Taxation
      between the Republic of Korea and the U.S. and the Convention and
      Agreement of Tax Exemption and Reduction between the Republic of Korea and
      U.S., engineering support, including, without limitation, the provision of
      engineering support services, is not taxable.

11.5  Governing Law. This Agreement shall be governed and interpreted in all
      respects under the laws of the State of New York, without regard to any
      conflicts of law provisions thereof.

11.6  Assignment. This Agreement shall be binding upon and inure to the benefit
      of each party's respective successors and lawful assigns; provided,
      however, that Samsung may not assign this Agreement, in whole or in part,
      without the prior written approval of HSNS. An "assignment" shall be
      deemed to include, without limitation, a merger of one party with a third
      party, whether or not the party is the surviving entity, any transaction
      or series of transactions whereby a third party acquires direct or
      indirect power to control the management and policies of the party,
      whether through the acquisition of voting securities, by contract, or
      otherwise, or the sale of more than fifty (50%) percent of the party's
      assets (whether in a single transaction or series of transactions). Any
      attempted assignment in violation of this Section 11.6 shall be void and
      of no effect.

11.7  Force Majeure. Each party to this Agreement shall be excused from any
      performance required of such party hereunder if, and only to the extent,
      such performance is rendered impossible or unfeasible due to any
      catastrophe or other


                      HSNS Confidential & Proprietary              Page 11 of 15
<PAGE>
      major event beyond such party's reasonable control and not due to the
      fault or negligence of such party, including, without limitation, war,
      riot, and insurrection; laws, proclamations, edicts, ordinances or
      regulations; strikes, lockouts or serious labor disputes; floods, fires,
      explosions, or other natural disasters. In the event of the occurrence of
      such a force majeure event, the party unable to perform shall promptly
      notify the other party, shall suspend performance only for such period of
      time as is necessary as a result of the force majeure event, and shall use
      its commercially reasonable best efforts to resume performance as quickly
      as possible.

11.8  Construction. If any one or more provisions of this Agreement shall be
      found to be illegal or unenforceable by a court of competent jurisdiction
      in any respect, the validity, legality and enforceability of the remaining
      provisions shall not in any way be affected or impaired thereby, provided
      the surviving agreement materially comports with the parties' original
      intent, and the remainder of this Agreement will continue in full force
      and effect. Failure by either party to enforce any provision of this
      Agreement will not be deemed a waiver of future enforcement of that or any
      other provision. This Agreement has been negotiated by the parties and
      their respective counsel and will be interpreted fairly in accordance with
      its terms and without any strict construction in favor of or against
      either party.

11.9. Entire Agreement. This Agreement constitutes the entire agreement between
      the parties with respect to the Services and all other subject matter
      hereof and merges all prior and contemporaneous communications. It shall
      not be modified except by a written agreement dated subsequent to the date
      of this Agreement and signed on behalf of Samsung and HSNS by their
      respective duly authorized representatives.

      IN WITNESS WHEREOF, the parties have entered into this Agreement as of the
Effective Date written above.

1.    Error Reporting. Samsung's designated technical contact shall promptly
      report via e-mail to HSNS all Errors in the Deliverables of which it

            performance in accordance with the Specifications of a major
            function.

            performance in accordance with the Specifications of a minor
            function.

      Term, if applicable, HSNS shall use reasonable efforts to respond to and
      resolve (to the extent reasonably possible) Errors reported in accordance
      with 1 above as set forth below (for the purposes of this Section, a day
      refers to a business day as opposed to calendar day):
