          - each CD-Audio Disc with an outer diameter equal to, or greater
                 than, 90mm;

which is made, used, sold or otherwise disposed of by Licensee or an

5.03  A Licensed Product shall be considered sold when invoiced, or if
      not invoiced, when delivered to a party other than the manufacturer.

      5.04 Within thirty (30) days after the 31st March, the 30th June, the 30th
           September and the 31st December of each year during the period this
           Agreement shall be in force and effect, Licensee shall submit to
           USPC, even if there are no sales, a statement in writing, duly
           certified by an officer of the Licensee, setting forth with respect
           to the preceding quarterly period:

           (i)  The quantities of Licensed Products sold by Licensee and its
                Associated Companies, specifying the quantities for each of the
                following individual type of Licensed Products:

                (a)  CD-Audio Discs with an outer diameter smaller than 90
                     mm;

                (b)  CD-Audio Discs with an outer diameter equal to, or
                     greater than 90 mm;

                (c)  CDV Discs with an outer diameter equal to, or greater
                     than 130 mm;

                (d)  CDV Discs with an outer diameter smaller than 130 mm;

                (e)  CD-ROM Discs;

                (f)  CD-i Discs;

                                       22
<PAGE>

                  (g)  Enhanced Music DC Discs;

        and

             (ii) the royalty payable to USPC as calculated under the terms of
        this Agreement.

             Licensee shall pay to USPC the royalty due hereunder in U.S.
        dollars concurrently with submission of the above mentioned
        statement.

        5.05 Royalties shall be due and payable on all Licensed Products
             manufactured prior to, but remaining in stock with Licensee and
             its Associated Companies at the date of expiration or
             termination of this Agreement. Certified reports on the number
             of Licensed Products in stock at the time of expiration or
             termination of this Agreement shall be submitted to USPC within
             thirty (30) days after such expiration or termination. For the
             purpose of royalty computation it shall be assumed that all
             Licensed Products in stock will be sold, leased or otherwise
             disposed of in the same countries and in proportionally the same
             quantities as in the last full six (6) months period reported on
             during the term of this Agreement. Payment of royalties due
             shall be effected concurrently with the

                                       23
<PAGE>

             submission of said certified report.

        5.06 All payments which are not made on the dates specified herein,
             shall accrue interest at the rate of two percent (2%) per month
             or the maximum permitted by applicable law, whichever is less.

        5.07 All costs, such as stamp duties, taxes and other similar levies
             originating from or in connection with the conclusion of this
             Agreement shall be borne by Licensee. However, in the event that
             the government of a country imposes any income taxes on payments
             hereunder by Licensee to USPC and requires Licensee to withhold
             such tax from such payments, Licensee may deduct such tax from
             such payments. In such event, Licensee shall promptly furnish
             USPC with tax receipts issued by appropriate tax authorities so
             as to enable USPC to support a claim for credit against income
             taxes which may be payable by USPC and/or its Associated
             Companies in the Netherlands.

        5.08 In order that the royalties and reports provided for in this
             Article V may be verified, Licensee agrees to ensure that full,
             complete and accurate books and records shall be kept covering
             all sales or other disposals of Licensed

                                       24
<PAGE>

             Products by Licensee and/or its Associated Companies, for a
             period of three (3) years following such sales or other
             dispositions. It is agreed that the books and records of
             Licensee and/or its Associated Companies may be audited from
             time to time, but not more than once in each calendar year, by
             an independent certified public accountant appointed by USPC and
             reasonably acceptable to Licensee, to the extent necessary to
             verify the accuracy of the aforementioned statements and
             payments. Such inspection shall be completed at USPC's own
             expense provided that if any discrepancy or error exceeding
             three percent (3%) of the money actually due is found in
             connection with the computation, the cost of such inspection
             shall be borne by Licensee.

        5.09 Notwithstanding the provisions of Paragraph 5.08 of this Article
             V, Licensee shall furnish whatever additional information as
             USPC may reasonably request from time to time to enable USPC to
             ascertain which products sold, leased or put into use by
             Licensee and/or its Associated Companies are subject to the
             payment of royalties to USPC hereunder, the patent rights which
             have been utilized in

                                       25
<PAGE>

             connection with such products, and the amount of royalties payable.

                    ARTICLE VI - MOST FAVORABLE CONDITIONS

     If under otherwise substantially the same conditions as contained in
this Agreement, licenses under the patent rights referred to and licensed
pursuant to Article II should be granted for Licensed Products to any third
party at a royalty rate more favorable than the rate payable by Licensee
under this Agreement, Licensee shall be entitled to have the royalty rate
applicable to it modified to such extent that the same shall be as favorable
as that available to such third party, provided always that such obligation
shall not apply in respect of cross-license agreements and other agreements,
in which the consideration for such licenses shall not be wholly expressed in
payment of royalties and shall also not apply to licenses or other
arrangements made pursuant to a court decision or a settlement of a dispute
between USPC and a Licensee or between USPC and a third party. Without
limiting the foregoing, this Article VI shall not apply to terms entered into
in settlement of a filed court action regardless of the nature of such action
or settlement terms.

                           ARTICLE VII - DISCLAIMER

     USPC warrants that it shall furnish the information to be supplied by it
to the best of its ability, but it makes no representation or warranty as to
the value of the information transmitted or the ability of Licensee to make
use thereof to secure interchangeability. USPC makes no warranty whatsoever
that the use of information supplied by USPC does not infringe or may not
cause infringement of patent rights owned or controlled by third parties, or
of patent rights owned or controlled by USPC or an Associated Company of USPC
not licensed pursuant to Article II.

     In further certainty the parties of this Agreement recognize that third
parties own patent rights in the field of Licensed Products and Licensee
accepts that USPC makes no warranty whatsoever that any manufacture, use,
sale, lease or other disposition of Licensed Product will be free from
infringement of any patent other than Licensed Patents.


                            ARTICLE VIII - SECRECY

     Licensee agrees that, subject to what has been provided for in Article
IV of this Agreement, Licensee and its Associated Companies shall not
disclose to any third party

                                       27
<PAGE>

information relative to the manufacture and sale of Licensed Products
acquired from USPC or USPC's Associated Companies. This obligation, which
shall run for the period of this Agreement and for a period of three (3)
years thereafter, shall not apply to the extent information so acquired:

(a)  was known to Licensee or its Associated Companies prior to the date
     said information was acquired from USPC or its Companies, as shown by
     records of Licensee or any Company of Licensee or otherwise demonstrated
     to Philips' satisfaction;

(b)  is or has become available to the public in general through no fault of
     Licensee or its Companies;

(c)  was or is received from a third party who was free and had a legal right
     to disclose the same.

     In protecting information acquired from USPC or their Companies
pertaining to Licensed Products, Licensee has agreed that Licensee and its
Companies will take all necessary measures and precautions, including, but
not limited to, measures requiring their present and future employees to give
suitable undertakings of secrecy both for the period of their employment and
thereafter, and that in general such information

                                       28
<PAGE>

will be treated in the same manner and with the same degree of care as
Licensee applies and has applied to its own information of a sensitive or
confidential nature.

                     ARTICLE IX - PATENT MARKINGS AND LOGO

9.01  If requested by USPC, Licensee shall place appropriate patent markings on
      an exposed surface of the Licensed Products made, used, sold and/or
      otherwise disposed of hereunder. The content, form, location and language
      used in such markings shall be in accordance with the laws and practices
      of the country, where such markings are used.

9.02  In addition, Licensed Products may be provided with respective logos in
      accordance with the instructions laid down in the CD Logo Guide which is
      available from USPC on request (hereinafter referred to as "the Logo"). In
      advertisements and sales literature with respect to Licensed Products sold
      by Licensee and/or its Companies the Logo may similarly be used and
      applied.

9.03  USPC grants Licensee and its Companies a royalty free, non-exclusive, non-
      transferable, indivisible right to use the Logo on and with respect to
      Licensed Products manufactured by or for Licensee and/or its

                                       29
<PAGE>

      Companies in accordance with the instructions laid down in Exhibit AA.

9.04  Licensee understands and agrees that USPC makes no warranty whatsoever
      that any use of the Logo will be free from infringement of intellectual
      property rights owned by third parties.

                            ARTICLE X - ASSIGNMENT

      This Agreement shall inure to the benefit of and be binding upon each of
the parties hereto and their respective assigns. It may not be assigned in whole
or in part by Licensee without the prior consent in writing of USPC except to
the surviving corporation of a merger, consolidation or other transfer of all or
substantially all the assets of Licensee and except that Licensee may assign
this Agreement to one of its Companies provided that Licensee remains liable
hereunder and the transferee has the capability to perform all obligations to be
performed hereunder.

                       ARTICLE XI - TERM AND TERMINATION

11.01 This Agreement shall be effective from the date first written above, if
      and unless otherwise terminated shall

                                       30
<PAGE>

       remain in force for a period of ten (10) years from the effective date
       of this Agreement. Notwithstanding the foregoing, this Agreement shall
       expire on the expiration date of the last to expire of the Licensed
       Patents licensed and referred to in Article II.

11.02  Either party may terminate this Agreement at any time on thirty (30)
       days notice to the other party in the event that the latter shall fail
       to perform any obligation under this Agreement and such default is not
       remedied within thirty (30) days after receipt of a notice specifying
       the nature of the default. Such right of termination shall not be
       exclusive of any other remedies or means of redress to which the
       non-defaulting party may be lawfully entitled, it being intended that
       all such remedies shall be cumulative. Any such termination shall not
       affect any payments, the rights to which may have fallen due  under
       this Agreement prior to such termination. Notwithstanding anything to
       the contrary herein, USPC shall have the right, at its sole option and
       discretion, to terminate this Agreement without advance notice (but
       with written notice) in the event that Licensee shall fail to abide by

                                       31
<PAGE>

       the obligations as set forth in Article V hereof for three (3)
       consecutive quarters.

11.03  The obligations set forth in paragraphs 2.02, 2.03, 2.04, 2.05, 5.05,
       12.05 and Article VIII shall survive termination of this Agreement.
       Notwithstanding the foregoing, in the event termination is due to the
       breach of the Agreement by Licensee, paragraphs 2.02 and 2.03 shall
       not survive termination.

11.04  If Licensee should be dissolved or file a voluntary petition in
       bankruptcy or seek any court of governmental protection from creditors
       or make any assignment for creditors, or should an order be entered
       pursuant to any law relating to bankruptcy or insolvency appointing a
       receiver or trustee for Licensee, and if any such receivership is not
       terminated within sixty (60) days, then, in any of the events
       specified in this paragraph 11.04, USPC may give written notice to
       Licensee terminating this Agreement and this Agreement shall be
       terminated in accordance with the notice.

                          ARTICLE XII - MISCELLANEOUS

12.01  This Agreement sets forth the entire agreement and

                                       32
<PAGE>

       understanding between the parties as to the subject matter hereof and
       merges all prior discussions between them and neither of the parties
       shall be bound by any conditions, definitions, warranties, waivers,
       releases or representations (either expressed or implied) with respect
       to the subject matter of this Agreement, other than expressly
       provided for herein, or as duly set forth on or subsequent to the date
       hereof in writing signed by a duly authorized representative of the
       party to be bound thereby.

12.02  Nothing contained in this Agreement shall be construed:

       (a)  as imposing on either party any obligation to institute any suit
            or action for infringement of any of the patent rights licensed
            hereunder or to defend any suit or action brought by a third
            party which challenges or concerns the validity of any of such
            patent rights, it being expressly understood that Licensee shall
            have no right to institute any such suit or action for
            infringement of any of the patent rights licensed by USPC
            hereunder, nor the right to defend any such suit or action which
            challenges or

                                       33
<PAGE>

            concerns the validity of any such USPC patent right;

       (b)  as imposing any obligation to file any patent application or to
            secure any patent or to maintain any patent in force;

       (c)  as conferring any license or right to copy or to simulate the
            appearance and/or design of any product of USPC or its Companies;

       (d)  as conferring any license under the patent rights licensed
            pursuant to Article II hereof to manufacture, use, sell, lease or
            otherwise dispose of any product or device other than a Licensed
            Product.

12.03  If at any time a party shall elect not to assert its rights under any
       provision of this Agreement, such action or lack of action in that
       respect shall not be construed as a waiver of its rights under said
       provision or of any other provision of this Agreement.

12.04  Any notice or request required or permitted to be given under or in
       connection with this Agreement or the subject matter hereof shall be
       in writing and shall be deemed to have been sufficiently given when,
       if given to Licensee,
