          in immediately available funds.

     3.8  Statements.  Licensee shall accompany each semi-annual payment with a
          statement showing in reasonable detail and separately identifying for
          each MPEG-2 Royalty Product the quantity Manufactured in each country
          and the quantity Sold in each country of any and all MPEG-2 Royalty
          Products Sold during such period by Licensee and its Affiliates, and
          a calculation of the royalties, if any, which are payable by virtue
          of such Manufacture and Sale of MPEG-2 Royalty Products during the
          semi-annual period when the payment, if any, accrued.

          3.8.1  Such statements shall be certified by an officer of Licensee
                 authorized to make such certification.

          3.8.2  The Licensing Administrator shall maintain all information in
                 such statements of Licensee as Confidential Information in
                 accordance with Article 5 of this Agreement, except to the
                 extent that the information is needed by the Licensing
                 Administrator to report to the Licensors the aggregate
                 royalties paid by all sublicensees of the Licensing
                 Administrator. In no event shall the Licensing Administrator
                 provide to any of the Licensors information on royalties paid
                 on a licensee-by-licensee or country-by-country basis unless
                 required by law.

     3.9  Audits.

          3.9.1  Books and Records.  Licensees shall keep and maintain accurate
                 and detailed books and records adequate for the Licensing
                 Administrator to ascertain the royalties payable hereunder.
                 Such books and records shall be maintained for three (3) years
                 from the end of each period when royalties are payable.

          3.9.2  Audit Rights.  The Licensing Administrator shall have the right
                 to audit or have audited the books and records of Licensee
                 relating to payments

                                      -15-

                   hereunder for the sole purpose of verifying the amounts due
                   and payable hereunder, not more than once per calender year
                   upon reasonable notice to the Licensee. All such audits shall
                   be conducted during reasonable business hours of the
                   Licensee.

          3.9.2.1  Any such audit shall be performed by an independent
                   certified public accountant(s) or equivalent (Auditor)
                   reasonably acceptable to Licensee in the country where the
                   audit is to take place. Licensee shall fully cooperate with
                   Auditor in conducting such audit and shall permit Auditor to
                   inspect and copy such portions of the Licensee's books and
                   records that the Auditor deems appropriate and necessary in
                   accordance with the professional standards applicable to the
                   Auditor in the country where the Audit is to take place.

          3.9.2.2  The Auditor (and each member or employee thereof
                   participating in the audit) shall agree not to disclose any
                   information learned by the Auditor in the audit to any
                   Licensor, nor use any such information, except for providing
                   the Licensing Administrator with a statement of payments due
                   by Licensee.

          3.9.2.3  The cost of an audit in accordance with Paragraph 3.9.2 of
                   this Agreement shall be at the expense of the Licensing
                   Administrator; provided, however, the Licensee shall bear the
                   cost of the audit if the audit reveals any underpayment which
                   in the aggregate is greater than five percent (5%) of the
                   amount actually due for the period being audited.

          3.9.2.4  Licensee shall pay any shortfalls uncovered in accordance
                   with Paragraph 3.9.2 of this Agreement, plus interest as set
                   forth in Section 3.6 herein, within thirty (30) Days after
                   receiving notice from the Licensing Administrator of such
                   shortfall.

4.   REPRESENTATIONS AND WARRANTIES

     4.1  The Licensing Administrator represents and warrants that it has the
          authority, power and right to grant the rights and licenses to
          Licensee under this Agreement.

                                      -16-
<PAGE>   17
     4.2  The Licensing Administrator makes no representation or warranty that
          the MPEG-2 Patent Portfolio Patent(s) sublicensed hereunder includes
          all MPEG-2 Essential Patent(s) throughout the world, or that the
          making, using or selling of products, or providing services covered
          by the claims of the MPEG-2 Patent Portfolio Patent(s) licensed
          hereunder will not infringe, directly, contributorily or by
          inducement under the laws of the United States or under equivalents
          thereof under the laws of a country other than the United States, any
          patent or other intellectual property right of a party other than the
          MPEG-2 Patent Portfolio Patent(s).

     4.3  Licensee represents and warrants that it is entering into this
          Agreement for its own convenience in acquiring patent rights necessary
          for compliance with the MPEG-2 Standard from multiple licensors in a
          single transaction rather than entering into separate license
          agreements with individual licensors, and that Licensee is fully aware
          that the patents in the MPEG-2 Patent Portfolio may not include all
          present and future MPEG-2 Essential Patent(s), and that this Agreement
          may not provide Licensee with all the patent rights needed to perform
          the activities contemplated by Licensee in entering into this
          Agreement. The Licensing Administrator and Licensee recognize that
          Licensee has the right to separately negotiate a license with any or
          all of the Licensors under any and all of the MPEG-2 Patent Portfolio
          Patents under terms and conditions to be independently negotiated by
          each Licensor.

     4.4  Licensee represents and warrants that it has not granted an exclusive
          license under an MPEG-2 Essential Patent owned by Licensee and has not
          assigned an MPEG-2 Essential Patent in anticipation of entering into
          this Agreement. Notwithstanding anything to the contrary in this
          Agreement, Licensors reserve the right to grant to Licensing
          Administrator an exclusive license under any MPEG-2 Patent Portfolio
          Patent with respect to any particular party.

     4.5  Each party represents and warrants that it will comply with all
          applicable laws, regulations or ordinances pertaining to its
          performance hereunder.

     4.6  Each party represents and warrants that this Agreement and the
          transactions contemplated hereby do not violate any agreements each
          party has with its agents, employees, or Affiliates or third parties.

     4.7  Each party further represents and warrants that in executing this
          Agreement, it does not rely on any promises, inducements, or
          representations made by any party or third party with respect to this
          Agreement or any other business dealings with any party or third
          party, now or in the future.

                                      -17-

<PAGE>   18
     4.8  Each party represents and warrants that it is not presently the
          subject of a voluntary or involuntary petition in bankruptcy or the
          equivalent thereof, does not presently contemplate filing any such
          voluntary petition, and does not presently have reason to believe
          that such an involuntary petition will be filed against it.

     4.9  Other than the express warranties of this Article, there are NO OTHER
          WARRANTIES, EXPRESS OR IMPLIED.

5.   CONFIDENTIAL INFORMATION

     5.1  For a period of five (5) years as measured from the first date of
          disclosure pursuant to this Agreement, the Licensing Administrator
          agrees to use reasonable care and discretion, at least commensurate
          with that degree of care it uses to protect similar information of
          its own, to avoid disclosure, publication, or dissemination of
          received Confidential Information, outside of those employees or
          consultants of the Licensing Administrator who have a need to know
          Confidential Information.

     5.2  Disclosure by the Licensing Administrator of Confidential Information
          under Section 5.1 of this Agreement shall be permitted in the
          following circumstances; provided, that the Licensing Administrator
          shall have first given reasonable notice to Licensee that such
          disclosure is to be made:

          5.2.1  In response to an order of a court or other governmental body;

          5.2.2  Otherwise required by law; or

          5.2.3  Necessary to establish rights under this Agreement.

     5.3  Notwithstanding any other provisions of this Agreement, the
          obligations specified in Section 5.1 of this Agreement will not apply
          to any information that:

          5.3.1  Is or becomes publicly available without breach of this
                 Agreement; or

          5.3.2  Is released for disclosure by written consent of the Licensee.

6.   TERM AND TERMINATION

     6.1  Term and Certain Royalty Rates on Renewal. This Agreement shall expire
          on December 31, 2004. Upon expiration, Licensee shall have the right
          to renew this sublicense for successive five year periods for the life
          of any MPEG-2 Patent Portfolio Patent, subject to reasonable amendment
          of the royalty terms and rates set forth in this sublicense. Such
          reasonable amendment may take into account prevailing market
          conditions, changes in technological environment, and available
          commercial products at the time of each five year renewal. In no event
          shall the royalty rates upon each renewal of this sublicense increase,
          if at all, by more than 25% of the royalty rates set forth in this
          sublicense immediately prior to renewal. The preceding sentence,
          however, shall not apply to the Licensing Administrator's request at
          the time of renewal that royalty rates for MPEG-2 Packaged Media which
          ultimately are offered for rental to consumers be higher than royalty
          rates for MPEG-2 Packaged Media set forth in this sublicense at the
          time of renewal. Such request for higher royalty rates shall only be
          made by the Licensing Administrator, if at all, in the event that the
          majority of Licensees which are unaffiliated with entities which own
          copyrights on Movies charge different rates for replication of MPEG-2
          Packaged Media depending on whether such MPEG-2 Packaged Media is
          offered to consumers for sale or rental.

     6.2  Termination for Material Breach. The Licensing Administrator shall
          have the right to terminate this Agreement upon breach of a material
          provision thereof by the Licensee. Such termination for material
          breach shall become effective upon the Licensing Administrator
          sending written notice to the Licensee specifying the breach, and the
          failure of the Licensee to demonstrate, to the satisfaction of the
          Licensing Administrator, that Licensee has cured such breach within
          sixty (60) Days of the sending of such notice. The following are
          examples of acts or omissions which constitute a material breach of
          this Agreement:

          6.2.1  Failure of the Licensee to make payments and provide
                 statements in accordance with Sections 3.2 and 3.8 of this
                 Agreement;

          6.2.2  Failure of the Licensee to maintain adequate books and records
                 in accordance with Paragraph 3.9.1 of this Agreement or to
                 permit an audit in accordance with Paragraph 3.9.2 of this
                 Agreement; or

          6.2.3  Failure of the Licensee to grant licenses to MPEG-2 Essential
                 Patent(s) licensable or sublicensable by Licensee in
                 accordance with Sections 7.3 or 7.4 of this Agreement.

                                      -19-
<PAGE>   20
          6.2.4  The foregoing list is by way of example and not limitation.

     6.3  Partial Termination in the Event of Litigation. The Licensing
          Administrator, upon the instruction of a Licensor, shall terminate
          Licensee's sublicense under any MPEG-2 Patent Portfolio Patent(s)
          licensed or sublicensed to the Licensing Administrator by such
          Licensor in the event that the Licensee has brought a lawsuit or other
          proceeding for infringement of an MPEG-2 Related Patent(s) and/or an
          MPEG-2 Essential Patent(s) against such Licensor, and Licensee has
          refused to grant the Licensor a license on fair and reasonable terms
          and conditions under the MPEG-2 Related Patent(s) and/or MPEG-2
          Essential Patent(s) upon which the lawsuit or other proceeding is
          based. For purposes of this Section 6.3 only, the Licensor's per
          patent share of royalties payable pursuant to Section 3.1 of this
          Agreement shall be presumed to be a fair and reasonable royalty rate
          for Licensee's Patent(s) considering the essential nature of
          Licensor's Patent(s) licensed hereunder.

     6.4  Voluntary Termination. Licensee may terminate this Agreement by
          providing thirty (30) Days written notice to the Licensing
          Administrator.

     6.5  Other Terminations. This Agreement may be terminated by the Licensing
          Administrator upon the occurrence of the following events:

          6.5.1  If Licensee files a petition in bankruptcy or the equivalent
                 thereof, or is the subject of an involuntary petition in
                 bankruptcy that is not dismissed within sixty (60) Days after
                 the filing date thereof, or is or becomes insolvent, or admits
                 of a general inability to pay its debts as they become due.

          6.5.2  Upon the de facto or de jure nationalization or expropriation
                 of Licensee by governmental or military action, whether or not
                 with valid authority.

          6.5.3  Upon any failure by Licensee to provide, within thirty (30)
                 Days after written notice from the Licensing Administrator,
                 satisfactory and adequate assurances that Licensee is able and
                 willing to fully and effectively perform its obligations under
                 this Agreement.

          6.5.4  In the event that any of the events listed in Sections 6.5.1,
                 6.5.2 or 6.5.3 hereof occur, this Agreement may be terminated
                 by the Licensing Administrator upon thirty (30) Days written
                 notice to Licensee, without right to cure.

                                      -20-
<PAGE>   21
     6.6  Survival. The following provisions of this Agreement shall survive
          expiration or termination of this Agreement:

          6.6.1  The obligation of Licensee to pay all royalties accrued as of
                 the effective date of expiration or termination pursuant to
                 Section 3.3 hereof;

          6.6.2  The obligation of Licensee to provide statements under Section
                 3.8 of this Agreement; and

          6.6.3  The obligation of the Licensing Administrator to maintain
                 confidentiality under Article 5 of this Agreement.

7.   MISCELLANEOUS PROVISIONS

     7.1  Assignment.

          7.1.1  In the event that the right of the Licensing Administrator to
                 grant MPEG-2 Patent Portfolio Licenses is transferred to a
                 successor Licensing Administrator, this Agreement shall be
                 deemed assigned to the successor Licensing Administrator.

          7.1.2  This Agreement may not be assigned by the Licensee, other than
                 to a successor of the entire interest of an Affiliate or
                 business division of Licensee manufacturing or selling Licensed
                 Products, or providing a service in compliance with the MPEG-2
                 Standard, or to a purchaser of substantially all of the assets
                 of Licensee or such Affiliate or business division thereof.

     7.2  Notice.

          7.2.1  All notices required or permitted under this Agreement shall be
                 sent by either Certified Mail with return receipt requested or
                 by overnight delivery by commercial or other service which can
                 verify delivery. Such notices so sent shall be effective as of

     7.3  Licensee Grant. Licensee agrees to grant a worldwide, nonexclusive
          license and/or sublicense under any and all MPEG-2 Essential Patent(s)
          that Licensee or its Affiliate(s), if any, has the right to license
          and/or sublicense, to any Licensor or any sublicensee of the Licensing
          Administrator desiring such a license and/or sublicense on fair and
          reasonable terms and conditions. For purposes of this Section 7.3
          only, the Licensors' per patent share of royalties payable pursuant to
          Section 3.1 of this

                                      -22-
<PAGE>   23
          Agreement shall be presumed to be a fair and reasonable royalty rate
          for the aforementioned license and/or sublicense to be granted by the
          Licensee.

          7.3.1  Licensee's obligation to grant licenses and/or sublicenses
                 pursuant to Section 7.3 of this Agreement shall be effective
                 upon execution of this Agreement.

     7.4  Licensee's Option. In lieu of Section 7.3 Licensee shall have the
          option to hereby grant a worldwide, nonexclusive, nontransferable,
          except to a successor Licensing Administrator, license and/or
          sublicense under any and all of its MPEG-2 Essential Patent(s) to the
          Licensing Administrator with the right by the Licensing Administrator
          to grant MPEG-2 Patent Portfolio Licenses that include the MPEG-2
          Essential Patent(s) that Licensee or its Affiliate(s), if any, has the
          right to license or sublicense. Licensee shall identify to the
          Licensors any and all of its patents and patents of its Affiliate(s),
          if any, which Licensee believes in good faith to be MPEG-2 Essential
          Patent(s). Licensors shall determine whether each of the patent(s)
          identified by Licensee is an MPEG-2 Essential Patent(s) according to
          an established procedure applicable to all new patents identified to
          the Licensors. The terms and conditions of the license and/or
          sublicense granted by the Licensee to the Licensing Administrator
          under this Section 7.4 shall be identical to the terms and conditions
          of the license and/or sublicense granted by each Licensor to the
          Licensing Administrator. If Licensee elects the option set forth in
          this Section 7.4, it shall be required to enter into an agreement
          referred to as the "Agreement Among Licensors," which has been entered
          into by all Licensors.

     7.5  Licensee Covenants.

          7.5.1  Licensee hereby covenants to promptly notify the Licensing
                 Administrator in the event that any allowed patent
                 application(s) published for opposition, which is licensed or
                 sublicensed to the Licensing Administrator pursuant to Section
                 7.4 of this Agreement as an MPEG-2 Essential Patent(s), does
                 not issue as an MPEG-2 Essential Patent(s).

          7.5.2  Licensee shall promptly identify to the Licensing Administrator
                 each patent(s), except for MPEG-2 Patent Portfolio Patents of
                 the Licensors, licensable or sublicensable by Licensee or its
                 Affiliate(s), if any, which Licensee believes in good faith to
                 be an MPEG-2 Essential Patent(s) within fourteen (14) Days of
                 execution of this Agreement.

          7.5.3  In the event that Licensee has granted an exclusive license to
                 a third party under an MPEG-2 Essential Patent(s) prior to the
                 date of execution of this Agreement, Licensee shall advise the
                 Licensing Administrator of such an exclusive license and
                 identify to the Licensing Administrator such third party.

     7.6  Licensing Administrator Covenants.

          7.6.1  The Licensing Administrator covenants that if during the term
                 of this Agreement, it acquires rights to grant sublicenses
                 under additional MPEG-2 Essential Patent(s), the MPEG-2 Patent
                 Portfolio License herein will be supplemented to include such
                 additional MPEG-2 Essential Patent(s).

          7.6.2  The Licensing Administrator covenants that, with the exception
                 of partial termination under Section 6.3 of this Agreement, any
                 deletion from the MPEG-2 Patent Portfolio shall occur only upon
                 a determination by the Licensors, or upon a final adjudication
                 of a tribunal of competent jurisdiction from which no appeal is
                 taken or allowed, that the deleted Patent(s) is invalid or
                 unenforceable in the country which issued or published the
                 Patent(s), and that any addition to the MPEG-2 Patent Portfolio
                 shall occur only upon the determination by the Licensors that
                 the additional Patent(s) is an MPEG-2 Essential Patent(s) in
                 the country which issued or published the Patent(s).

          7.6.3  The Licensing Administrator further covenants that if any
                 Patent(s) in the MPEG-2 Patent Portfolio is found not to be an
                 MPEG-2 Essential Patent(s) in the country which issued or
                 published the Patent(s), either by the Licensors or upon a
                 final adjudication of a tribunal of competent jurisdiction
                 from which no appeal is taken or allowed and such Patent(s) is
                 to be deleted from the MPEG-2 Patent Portfolio, the Licensing
                 Administrator shall give notice to Licensee of such deletion,
                 and Licensee shall have the option to retain its sublicense
                 under the deleted Patent(s) for the remainder of the term of
                 this Agreement, including any renewal pursuant to Section 6.1
                 hereunder.

          7.6.4  The Licensing Administrator covenants that it shall not delete
                 from or add to the MPEG-2 Patent Portfolio for reasons other
                 than stated in Paragraphs 7.6.1 and 7.6.2 and Section 6.3
                 herein.

          7.6.5  The Licensing Administrator covenants that the royalties set
                 forth in Section 3.1 of this Agreement shall not increase
                 during the term of this Agreement, as set forth in Article 6
                 of this Agreement.

     7.7  Most Favorable Royalty Rates. Except as provided in Paragraph 7.7.1 of
          this Agreement, in the event that the Licensing Administrator grants
          an MPEG-2 Patent Portfolio License to another party with royalty rates
          more favorable than those set forth in Section 3.1 of this Agreement,
          whether or not such more favorable royalty rates are on terms and/or
          conditions that are different than those set forth herein, the
          Licensing Administrator shall send written notice to Licensee
          specifying the more favorable royalty rates and any terms and/or
          conditions that are different than those set forth herein within
          thirty (30) Days of the granting of the MPEG-2 Patent Portfolio
          License providing for such more favorable royalty rates. Licensee
          shall be entitled to an amendment of this Agreement to the extent of
          providing for royalty rates as favorable as that available to such
          other party within thirty (30) Days of sending written notice to the
          Licensing Administrator requesting such amendment; provided, however,
          that this Agreement shall also be amended to include any additional
          benefits to the Licensing Administrator. Any amendment made pursuant
          to this Section 7.7 shall be effective as of the date it is made, and
          such more favorable royalty rates shall not be retroactively
          applicable in favor of the Licensee, and shall not be a basis for
          claiming any refund of royalties paid prior to such effective date.

          comply with the MPEG-2 Standard.

          a principal-agent relationship, partnership or joint venture between

          other party.

     7.10 Severability.  If any provision of this Agreement is held by a court
          of competent jurisdiction to be unenforceable or contrary to law, the
          remaining provisions of the Agreement will remain in full force and
          effect.

     7.11 No Waiver.  The failure of either party at any time to require
          performance by the other party of any provision of this Agreement
          shall not be construed as acquiescence or waiver of such failure to
          perform such provision. The failure of either party to take action
          upon the breach of any provision of this Agreement shall not be
          construed as acquiescence or waiver of any such breach.
