          - 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

      5.04 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,

                    NON-EXCLUSIVE PATENT LICENSE AGREEMENT
                                      FOR
                          DISC PRODUCT MANUFACTURERS

       This AGREEMENT is made effective this 1st day of June, 1996, by and
between DISCOVISION ASSOCIATES, a joint venture subject to the State of
California partnership law, having a place of business at 2355 Main Street,
Suite 200, Irvine, California 92714, United States of America (hereinafter
referred to as DVA) and FUTURE MEDIA PRODUCTIONS, a California corporation,
having a place of business at 25136 Anza Drive, Valencia, California 91355
(hereinafter referred to as LICENSEE), who agree as follows:

SECTION 1.0  RECITALS

1.1    DVA has the right to grant licenses under certain DVA-owned United
       States and Canadian patents relating to the design, manufacture,
       and sale of optical disc products such as compact discs and
       CD-ROM discs.

1.2    DVA is prepared to grant non-exclusive licenses under such patents on
       reasonable terms and conditions to financially sound and commercially
       responsible applicants.

1.3    LICENSEE has produced and/or sold and intends to continue producing
       and/or selling products which may embody patented inventions covered
       by such DVA patents or which may be made using apparatus or methods
       which may embody such patented inventions. These products are
       manufactured by: (1) LICENSEE; (2) manufacturers licensed by DVA who
       do not pay United States and Canadian royalty rates; (3)
       manufacturers licensed by DVA who pay United States and Canadian
       royalty rates; or (4) manufacturers not licensed by DVA. As
       specified later in this Agreement, the amount of any royalty to be
       paid by LICENSEE to DVA depends partly on the source of the product.

1.4    DVA is offering LICENSEE, as an option herein, a license under
       individual ones of its patents, the availability of such license
       under any one or more of DVA's patents being in no way conditioned on
       the need for LICENSEE to take a license under any other DVA's
       patents.
<PAGE>

1.5    LICENSEE has determined that its business interests will be best served
       by taking a license under the terms and conditions of this Agreement.
       In so doing, LICENSEE understands that if less than all DVA patents
       are licensed, then licenses under additional DVA patents may be
       required before LICENSEE can make or sell optical disc products free
       and clear of all claims of patent infringement by DVA. Information
       regarding infringement of additional DVA patents may be obtained by
       using the factory inspection provisions of Section 10.0 herein.

       insurance fees and

                                 Page 5 of 23
<PAGE>

       packing and transportation charges incurred by LICENSEE and invoiced
       separately to a third party; (3) duties and sales taxes actually incurred
       and paid by LICENSEE in connection with delivery of such Licensed
       Product; (4) the cost of any copyright license fee paid by LICENSEE in
       respect of information stored on the Licensed Product; and (5) pre-
       mastering charges incurred by LICENSEE and necessary for the manufacture
       of the Licensed Product, which pre-mastering charges are invoiced
       separately to a third party. Manufacturer's Net Selling Price shall
       include all mastering charges, including but not limited to charges
       incurred for Manufacturing Apparatus used in the mastering process,
       whether such mastering charges are incurred as the result of LICENSEE's
       own Manufacturing Apparatus, or from mastering charges invoiced
       separately to a third party, such as LICENSEE's purchase of a stamper
       from a third party. In respect of a Licensed Product used or leased by
       LICENSEE or its Affiliate or sold or Transferred in other than Arm's
       Length Trade by LICENSEE or its Affiliate, the Manufacturer's Net Selling
       Price shall be deemed to be equal to the average Manufacturer's Net
       Selling Price as defined above for the same or equivalent Licensed
       Product sold in Arm's Length Trade during the then current accounting
       period. In the event there are no sales in Arm's Length Trade during an
       accounting period, DVA and LICENSEE shall attempt to agree upon an amount
       to be regarded as the Manufacturer's Net Selling Price for such
       accounting period. If DVA and LICENSEE do not so agree, then
       Manufacturer's Net Selling Price shall mean the actual selling price to
       an ultimate consumer. If a Licensed Product is not separately sold and is
       included with other apparatus, then the Manufacturer's Net Selling Price
       of such Licensed Product shall be the Manufacturer's Net Selling Price of
       the equivalent Licensed Product which is separately sold, or, if no such
       equivalent Licensed Product exists, shall be, at LICENSEE's option,
       either: (1) the price as aforesaid of such other apparatus multiplied by
       the ratio of the Manufacturing Cost of such Licensed Product to the
       Manufacturing Cost of such other apparatus; or (2) one hundred and fifty
       percent (150%) of the Manufacturer's Net Selling Price of that part of
       the apparatus that constitutes the Licensed Product.

2.26   "Manufacturing Cost" shall mean total cost of direct materials, direct
       and indirect factory labor and factory overhead determined in accordance
       with sound accounting principles.

SECTION 3.0 NON-EXCLUSIVE LICENSE GRANT

3.1    DVA grants to LICENSEE a non-exclusive, royalty bearing license under
       the Licensed Patent(s):

       3.1.1  to make, have made, use, rent, lease, sell and/or Transfer
              Licensed Products in the United States of America and Canada and
              their territories and possessions; and

       3.1.2  to make, have made, use or have used Manufacturing Apparatus and
              to use or have used Manufacturing Processes in the United States
              of America and Canada and their territories and possessions to
              manufacture Licensed Products for LICENSEE.

       It is understood by LICENSEE that licenses under additional DVA Patent(s)
       not listed in Appendix B may be required before LICENSEE can make, use,
       rent, lease, sell and/or Transfer Licensed Products free and clear of all
       claims of patent infringement by DVA. LICENSEE may obtain from DVA a
       determination as to the applicability of any DVA Patent(s) to LICENSEE's
       products by use of the factory inspection provisions of Section 10.0 of
       this Agreement. In any event, DVA reserves the right to bring a patent
       infringement action against LICENSEE with respect to any DVA Patent(s)
       not listed in Appendix B.

3.2    No license is granted by DVA to LICENSEE in this Section 3.0, either
       expressly or by implication, estoppel, or otherwise:

       3.2.1  other than under the Licensed Patent(s) listed in Appendix B;

       3.2.2  with respect to any products other than Licensed Products;

       3.2.3  to rent, lease, sell and/or Transfer any Manufacturing Apparatus;
              or

       3.2.4  to rent, lease, sell and/or Transfer any Manufacturing Process or
              process step thereof.

3.3    The license granted herein shall include a sublicense to LICENSEE's
       Affiliates, identified in Appendix C, which are LICENSEE's Affiliates as
       of the effective date of this Agreement. LICENSEE shall pay and account
       to DVA for royalties hereunder with respect to the exercise by any
       Affiliate of LICENSEE of the sublicense granted to it hereunder, and if
       LICENSEE fails to make such payment or accounting, DVA reserves the right
       to seek directly from such Affiliate any

                                 PAGE 7 OF 23
<PAGE>

       royalties due and owing to DVA. Sublicenses will be granted to additional
       Affiliates of LICENSEE during the term of this Agreement upon receipt by
       DVA of written notices from LICENSEE setting forth the names and
       addresses of such additional Affiliates to be covered by this Agreement,
       provided each such notice is given before any sales of Licensed Products
       by the Affiliate named therein. Each Affiliate sublicensed under this
       Agreement shall be bound by the terms and conditions of this Agreement as
       if it were named herein in the place of LICENSEE. LICENSEE represents to
       DVA that it has the power to bind each such Affiliate to the terms and
       conditions of this Agreement and agrees to take whatever action is
       necessary to legally bind such Affiliates. The sublicense granted to an
       Affiliate shall terminate on the date such Affiliate ceases to be an
       Affiliate.

3.4    Except as set forth in Section 3.3, LICENSEE is expressly not granted
       the right to sublicense third parties under this Agreement.

SECTION 4.0 RELEASE
4.1    Upon payment of the consideration set forth in Section 5.8, DVA
       irrevocably releases LICENSEE and its Affiliates, identified in Appendix
       C, which are LICENSEE's Affiliates as of the effective date of this
       Agreement, from any and all claims of infringement of the Licensed
       Patent(s), which claims have been made or which might be made at any
       time, with respect to any Licensed Products used, rented, leased, sold,
       or otherwise Transferred by or for LICENSEE or its sublicensed Affiliates
       before the effective date of this Agreement, to the extent such Licensed
       Products would have been licensed hereunder had they been manufactured,
       used, rented, leased, sold, or otherwise Transferred after the effective
       date of this Agreement. This release shall not apply to any Licensed
       Product on which a royalty accrues after the effective date of this
       Agreement. This release applies only to the Licensed Patent(s) and does
       not apply to any other DVA Patent(s). LICENSEE may remain liable for
       infringement of other DVA Patent(s).

4.2    LICENSEE expressly represents that its Affiliates identified in Appendix
       C include all of LICENSEE's Affiliates as of the effective date of this
       Agreement.

SECTION 5.0  ROYALTIES AND OTHER PAYMENTS
5.1    LICENSEE shall pay, as hereinafter provided, earned royalties to DVA with
       respect to both of the following for:

                                 Page 8 of 23
<PAGE>

       5.1.1  each Licensed Product for which LICENSEE is licensed hereunder in
              the country of manufacture; and

       5.1.2  each Licensed Product for which LICENSEE is licensed hereunder in
              the country of use, rental, lease, sale or Transfer.

5.2    For each Licensed Product manufactured in the United States of America or
       Canada or their territories or possessions, no more than one royalty
       shall be due for such Licensed Product, regardless of the number of
       countries in which the use, distribution and sale of such Licensed
       Product occurs.

5.3    LICENSEE shall pay to DVA a royalty as set forth below in Section 5.4 or
       as set forth below in Section 5.5. LICENSEE's election between the
       royalty of Section 5.4 and the royalty of Section 5.5 shall be made in
       writing to DVA for each type of Licensed Product on or before submission
       of the royalty report for the first accounting period for which royalty
       is to be paid for such type of Licensed Product. This election, once
       made, cannot be changed except as provided herein. For any given
       accounting period, LICENSEE shall pay the same royalty for each Licensed
       Product of the same type.

       If Section 5.4 is selected, and LICENSEE subsequently wishes to change
       its royalty election, LICENSEE may change the royalty election by
       notifying DVA in writing, on or before submission of the royalty report
       for the next accounting period for which such royalties are to be paid,
       of LICENSEE'S election to pay royalties pursuant to Section 5.5 herein,
       and of the Licensed Patent(s) to be included in Appendix B. Appendix B
       shall thereupon be amended to list the Licensed Patent(s) in accordance
       with LICENSEE's written notification, LICENSEE shall be liable for
       royalty payments pursuant to Section 5.4 up to the date of DVA's receipt
       of written notice of LICENSEE's change of royalty election.

       If LICENSEE is considering an election to pay royalties pursuant to
       Section 5.5, LICENSEE may request a factory inspection in accordance with
       Section 10.0. If Section 5.5 is selected, DVA reserves the right to bring
       a patent infringement action against LICENSEE with respect to any DVA
       Patent(s) not listed in Appendix B.

       The royalty election may be changed from Section 5.5 to Section 5.4 by
       written agreement of the parties.

5.4    As a first option, LICENSEE shall pay to DVA each of the following
       royalties:

       5.4.1  For each Licensed Product which is manufactured, used, rented,
              leased, sold and/or Transferred by or for LICENSEE and/or its
              Affiliates, LICENSEE shall pay to DVA a royalty for:

              5.4.1.1   Digital Discs (except CD Single Discs): three cents
                        (U.S. $0.03) per information bearing layer; and

              5.4.1.2   CD Single Discs: two cents (U.S. $0.02) per information
                        bearing layer.

              5.4.1.3   With respect to each of the preceding Sections 5.4.1.1
                        and 5.4.1.2, LICENSEE shall have the option of paying a
                        royalty of three percent (3.0%) of the Manufacturer's
                        Net Selling Price.

5.5    As a second option, LICENSEE shall pay to DVA for each Licensed Product
       which is manufactured, used, rented, leased, sold and/or Transferred by
       or for LICENSEE and/or its Affiliates, a royalty equal to the sum total
       of the individual patent royalty rates of Licensed Patent(s) as a
       percentage of the Manufacturer's Net Selling Price of such Licensed
       Product, such individual rates being set forth in Appendix B.

5.6    No royalties shall be paid by LICENSEE for:

       5.6.1  Licensed Products manufactured for LICENSEE by any other DVA
              licensee, so long as the other DVA licensee has fully paid and
              reported royalties to DVA on such Licensed Products and has
              identified LICENSEE as the purchaser of such Licensed Products in
              its royalty reports to DVA. If the other DVA licensee has paid a
              partial royalty to DVA, then LICENSEE shall receive a credit for
              that partial royalty.

       5.6.2  Licensed Products manufactured by LICENSEE for any other DVA
              licensee, so long as the other licensee has fully paid and
              reported royalties to DVA on such Licensed Products, and LICENSEE
              has identified such other DVA licensee as the purchaser, and both
              LICENSEE and such other DVA licensee have both identified the
              other in their respective royalty reports due DVA reporting such
              transaction.

                               Page 10 of 23
<PAGE>

              If the other DVA licensee has paid a partial royalty to DVA, then
              LICENSEE shall a receive credit for that partial royalty.

5.7    Lists of manufacturers that have a valid patent license agreement for
       Licensed Products with DVA are listed in Appendix D-1 and D-2. These
       lists will be updated annually. If LICENSEE purchases Licensed Products
       from any manufacturer listed in Appendix D-2 (licensed manufacturers not
       paying U.S. and Canadian royalty rates), and uses, rents, leases, sells
       and/or Transfers such Licensed Products in the United States of America
       or Canada or their territories or possessions, then LICENSEE shall:

       5.7.1  pay to DVA a royalty of two United States cents (U.S. $0.02) per
              information bearing layer; or

       5.7.2  submit the royalty report described in Section 6.6 to both DVA and
              each such licensed manufacturer. If LICENSEE chooses this option,
              DVA will demand, where appropriate, payment of the owed royalties
              as specified in Section 5.7.1 from the licensed manufacturer. If
              the licensed manufacturer does not pay these royalties within
              sixty (60) days of DVA's demand, LICENSEE must pay these
              royalties. The fact that DVA seeks payment from the licensed
              manufacturer in no way absolves LICENSEE of liability for these
              royalties.

5.8    LICENSEE agrees to pay DVA within sixty (60) days of the execution of
       this Agreement, the sum of Twenty Thousand United States Dollars
       ($20,000) as additional consideration for the release granted LICENSEE in
       Section 4.0. This sum is not refundable and is not creditable toward
       royalties set forth in this Section 5.0. LICENSEE and its Affiliates are
       jointly and severally liable for this payment, and if LICENSEE fails to
       make this payment, then DVA reserves the right to seek such payment from
       any or all of LICENSEE's Affiliates.

Section 6.0  ACCRUALS, RECORDS AND REPORTS
6.1    Royalties shall accrue when any Licensed Product with respect to which
       royalty payments are required by Section 5.0 of this Agreement is sold
       (as evidenced by bill or invoice), first rented, first leased, first put
       into use or Transferred, whether or not payment is received by LICENSEE.
       On sales or Transfers between LICENSEE and its Affiliate for resale or
       for further Transfer, the royalty shall accrue at the time of sale or
       Transfer to the Affiliate.

       United States dollars. All royalties for an accounting period computed on
       invoiced amounts in currencies other than United States dollars shall be
       converted directly into United States dollars, without intermediate
       conversions to another currency, at the currency exchange rate quoted by
       either the United States edition of the Wall Street Journal or the head
       office of Citibank N.A. of New York, New York at the close of banking on
       the last business day of such accounting period.

6.3    An accounting period shall end on the last day of each March, June,
       September and December during the term of this Agreement. The first
       accounting period under this Agreement shall be for a period commencing
       as of the effective date of this Agreement. Within sixty (60) days after
       the end of each such period, LICENSEE shall furnish to DVA the written
       reports containing the information specified in Sections 6.4, 6.5 and 6.6
       hereof and shall pay to DVA all owed royalties accrued hereunder in favor
       of DVA to the end of each such period. If LICENSEE chooses the option
       specified in Section 5.7.2, LICENSEE shall also send the applicable
       licensed manufacturer a copy of the royalty report specified in Section
       6.6 within the same sixty-day period.

6.4    With respect to Licensed Products LICENSEE manufactures or purchases from
       a manufacturer not listed in either Appendix D-1 or D-2, LICENSEE shall
       submit a royalty report including the following information:

       6.4.1   identification by Type Number, brand name and/or label name,

               information required to show how such amount has been calculated

       In the event that Section 6.4.1. does not apply, LICENSEE shall so state.
       In the event no royalties are due, LICENSEE's report shall so state.

       manufacturer listed in Appendix D-1, LICENSEE shall submit a royalty
       report including the following information:

       6.5.1   identification by Type Number, brand name and/or label name,

               Product type pursuant to the provisions of Section 5.0, the
               amount of royalties due for each Licensed Product type, all
               information required to show how such amount has been calculated

       6.5.4   identification by Type Number, brand name and/or label name,
               Licensed Product type (for example, CD Digital Audio, CD-ROM,
               etc.), and quantity of each Licensed Product type which is
               available for sale by LICENSEE during the applicable account
               period which is exempt from royalty in accordance with Section
               5.6.

       In the event that either of Sections 6.5.1 and 6.5.4 do not apply,
       LICENSEE shall so state as to each such Section. In the event no
       royalties are due, LICENSEE's report shall so state.

6.6    With respect to Licensed Products LICENSEE purchases from a licensed,
       manufacturer listed in Appendix D-2, LICENSEE shall submit a royalty
       report for each such licensed manufacturer including the following
       information:

       6.6.2   the name of the licensed manufacturer, city and country of the
               manufacture, and the countries in which LICENSEE sold (as
               evidenced by bill or invoice), first rented, first leased, first
               put into use or Transferred those Licensed Products;

       6.6.3   the total number of Licensed Products purchased from the licensed
               manufacturer and the total number of information bearing layers;
               and

       6.6.4   the royalty rate specified in Section 5.7.1 (if applicable), the

               outstanding royalty owed DVA for Licensed Products purchased from
               the licensed manufacturer.

6.7    LICENSEE's royalty reports shall be certified by an officer of LICENSEE
       or by a designee of such officer to be correct to the best of LICENSEE's
       knowledge and information.

6.8    LICENSEE shall keep separate records in sufficient detail to permit the
       determination of royalties payable hereunder. At the request of DVA,
       LICENSEE will permit an independent auditor and/or technical consultant
       selected by DVA, or any other person or persons acceptable to both DVA
       and LICENSEE, to examine during ordinary business hours once in each
       calendar year such reports and other documents as may be necessary to
       verify or determine royalties paid or payable under this Agreement. Such
       auditor, technical consultant or other person(s) shall be instructed to
       report to DVA only the amount of royalties due and payable. If no request
       for examination of such records for any particular accounting period has
       been made by DVA within five (5) years after the end of said period, the
       right to examine such records for said period, and the obligation to keep
       such records for said period, shall terminate.

6.9    The fees and expenses of DVA's representatives performing any examination
       of record under Section 6.8 shall be borne by DVA. However, if an error
       in royalties of more than three percent (3.0%) if the total royalties due
       is discovered for any year examined, then the total fees and expenses of
       these representatives shall be borne by LICENSEE.

SECTION 7.0  INTEREST ON OVERDUE ROYALTIES AND OTHER PAYMENTS

       percent (1.5%) per month compounded monthly on any overdue royalty or
       other payment set forth in Section 5.0 herein, commencing on the date
       such royalty or other payment becomes due. If such interest rate exceeds
       the maximum legal rate in the jurisdiction where a claim therefor is
       being asserted, the interest rate shall be reduced to such maximum legal
       rate.

SECTION 8.0  ASSIGNMENTS
8.1    LICENSEE shall not assign any of its rights or privileges hereunder
       without the prior written consent of DVA, except to a successor in
       ownership of all or substantially all the assets of LICENSEE, which
       successor expressly assumes in writing the performance of all the terms
       and conditions of this Agreement to be performed by LICENSEE as if it
       were named herein in the place of LICENSEE. After any such assignment,
       LICENSEE shall no longer be licensed hereunder.

SECTION 9.0  LICENSE TO DVA
9.1    LICENSEE grants to DVA and its Affiliates an irrevocable, worldwide, non-
       exclusive, royalty-free license under LICENSEE's patents and patent
       applications to make, have made, use, lease, sell or otherwise Transfer
       products corresponding to the Licensed Products defined herein, and to
       make, have made, use or have used Manufacturing Apparatus in the
       manufacture of such products and to practice or have practiced
       Manufacturing Processes in the manufacture of such products. Said license
       to DVA and its Affiliates shall be effective as of the date LICENSEE
       first pays royalties in accordance with Section 5.0 hereof. Said license
       shall be with respect to all of LICENSEE's patents and patent
       applications, including utility models, design patents, divisionals,
       reissues, extensions, continuations, and reexaminations, under which
       patents and patent applications LICENSEE now has or hereafter, during the
       term of this Agreement, obtains the right to grant licenses to DVA of the
       scope granted herein.

9.2    The license as set forth in Section 9.1 shall not apply with respect to
       any patent of LICENSEE, if such grant would result in the payment of
       royalties by LICENSEE to third parties, except for payments to Affiliates
       of LICENSEE and payments to third parties for inventions made by said
       third parties while employed by LICENSEE or any of its Affiliates.

SECTION 10.0  FACTORY INSPECTION
10.1   At LICENSEE's request, DVA will perform a factory inspection at
       LICENSEE's Licensed Product manufacturing facility, or the Licensed
       Product manufacturing

                                 Page 15 of 23
<PAGE>

       facility of the manufacturer who supplies Licensed Products to LICENSEE,
       and thereafter provide LICENSEE with claim charts indicating which DVA
       Patent(s) listed in Appendix A apply to LICENSEE's products. If LICENSEE
       is not the manufacturer, it is LICENSEE's responsibility to obtain the
       authorization of the manufacturer for DVA to perform the desired factory
       inspection. LICENSEE shall pay to DVA an inspection fee of Fifty Thousand
       United States dollars (U.S. $50,000) for each Licensed Product
       manufacturing facility to be inspected, said fee to be paid prior to each
       inspection.

10.2   If LICENSEE notifies DVA that LICENSEE wishes to have the factory
       inspection set forth in Section 10.1, then LICENSEE agrees to allow, or
       to obtain authorization to allow, the representatives of DVA to inspect
       the manufacturing facility as follows:

       10.2.1  DVA's representatives shall be allowed to inspect those parts of
               the manufacturing facility which are directly related to the
               possible infringement of DVA Patent(s). The inspection shall be
               made during reasonable business hours as soon as practically
               possible after payment of the inspection fee by LICENSEE. DVA and
               LICENSEE shall determine by mutual agreement the time, duration
               and other detailed manner and schedule of such inspection.

       10.2.2  The employees at the manufacturing facility will be directed, to
               the best of LICENSEE's ability, to answer all questions asked by
               the DVA representatives and will allow the full and complete
               inspection, copying, videotaping and photographing of all
               documentation, machines, methods, and materials used in, at, or
               with a part of the manufacturing facility which LICENSEE has the
               right to disclose to others, as long as such questions and/or
               such part of the facility is directly related to the possible
               infringement. Any notes made by the DVA representatives and any
               documents, photographs, and videotapes shall be stamped
               "CONFIDENTIAL."

      10.2.3   Any inspection of a Licensed Product manufacturing facility shall
               be on a confidential basis, and information learned as a result
               thereof shall be used for no purpose other than the technical
               discussions set forth herein. DVA shall safeguard the
               confidential information learned with standards at least as high
               as those that it uses to safeguard its own confidential
               information.

                                 Page 16 of 23
<PAGE>

      10.2.4  DVA shall not divulge any information obtained or learned as a
              result of such inspection to any other person or entity other
              than LICENSEE, including but not limited to other DVA licensees.
              This obligation shall not apply to information which is or
              becomes publicly available through no fault of DVA or is
              rightfully obtained without a bind of secrecy.

      10.2.5  DVA shall use its best efforts to provide, within sixty (60)
              days from the inspection of the Licensed Product manufacturing
              facility, a report in writing to LICENSEE. The report shall
              include those DVA Patent(s) which DVA believes are infringed by
              such facility and shall be in the form of claim charts providing
              the basis and reasons for the possible infringement of the DVA
              Patent(s) in question.

              DVA shall use its best efforts to include in the report all DVA
              Patent(s) which DVA believes are infringed by such facility. It
              is understood and agreed by LICENSEE that the exclusion of one
              or more DVA Patents neither stops DVA from asserting a claim of
              infringement against LICENSEE under such DVA Patent(s), nor
              affects the rights of DVA in any way with respect to such DVA
              Patent(s).

              It is understood and agreed by LICENSEE that this report and
              these claim charts are for settlement purposes only and cannot
              and will not be used for any other purpose. LICENSEE agrees to
              keep this report and these claim charts confidential and not to
              disclose them to any other party.

10.3  LICENSEE can elect this inspection option once per calendar year. Any
      inspection of a Licensed Product manufacturing facility after the first
      inspection of such manufacturing facility shall be performed for a fee
      to be determined and agreed upon between DVA and LICENSEE.

Section 11.0 TERM OF AGREEMENT; TERMINATION
11.1  Subject to Section 11.5 below, the term of this Agreement shall be from
      the effective date hereof until the expiration of the last to expire of
      the Licensed Patent(s), unless previously terminated as hereinafter
      provided.

11.2  LICENSEE may terminate the license granted herein, but only in its
      entirety, at any time by giving notice in writing to DVA. Such
      termination shall be effective on the date such notice is received by
      DVA.
