exceed such limits, MBC shall reimburse InterTrust no later than thirty (30)
days after submission by InterTrust to MBC of commercially reasonable
documentation of such costs and expenses above such limits, except insofar as
alternative cost and expense terms and conditions are required by any
Cooperative Application Project Plan, such as prepayment for contemplated costs
to be incurred. Calculations of InterTrust's costs and expenses shall be made
net of reimbursement payments made by MBC (e.g., if MBC reimburses InterTrust
                                           ---
for costs and expenses in excess of US$100,000 during a calendar year, such
reimbursed costs and expenses shall not count against such US$200,000 limit).

               ------------------------------------------
     and conditions of this Agreement, InterTrust grants to MBC during the term
     of this Agreement a limited, nonexclusive, nontransferable (except as
     expressly provided in Section 5.3), worldwide right and license under the
     Licensed Rights to perform Clearinghouse Functions solely under the MBC
     Trademarks, and solely in cases in which MBC performs and controls such

              Model Exclusive Right shall be solely of the scope granted
              pursuant to Sections 4.1 and 5.2(a) hereof, as applicable.

          (d) License to InterTrust Trademarks.  Subject to the terms and
              --------------------------------
     conditions of this Agreement, InterTrust grants to MBC during the term of
     this Agreement a limited, nonexclusive, nontransferable, worldwide license
     to use and display the InterTrust Trademarks solely: (i) on MBC Products,
     Cooperative Applications, and with respect to associated services to

     and marketing materials to identify that InterTrust Technology is being
     utilized by MBC; and (iii) as may be reasonably stipulated in writing by
     InterTrust.  InterTrust shall have the right to approve all uses of
     InterTrust Trademarks, including use thereof on MBC Products and
     Cooperative Applications, in connection with services (including
     performance of Clearinghouse Functions) provided by MBC relating to such
     products and applications, and in related documentation and marketing
     materials.  MBC shall comply with InterTrust's trademark guidelines as set
     forth herein, including in Section 6.4 hereof.

     5.3  Sublicense Rights.   Upon MBC's exercise of the Option in accordance
          -----------------
with Section 5.1, and solely as stipulated in this Section 5.3, MBC may enter
into sublicense agreements pursuant to which MBC may authorize certain other
entities to perform portions of the actions licensed to MBC under Sections
5.2(a) and 5.2(b) hereof. Sublicense agreements relating to MBC's rights under:
(i) Sections 5.2(a)(i), 5.2(a)(ii) and 5.2(a)(iii) shall be governed by Section
5.3(a), below; and (ii) Section 5.2(b) shall be governed by Section 5.3(b),
below. All sublicensees must, at a minimum, enter into an agreement with MBC and
with InterTrust pursuant to which such sublicensee agrees in writing to perform
all obligations of MBC and to be bound by all restrictions on MBC under Sections
5.2, 5.4, 5.5, 6.1, 6.2, 6.3, 6.4 and 6.5, and Articles 7, 8, 9, 10, 11, 12, 13
and 14 of this Agreement. In addition, MBC shall guarantee and remain liable to
InterTrust for all sublicensees' performance of such obligations. Sublicensees
shall have no further right to sublicense any right under this Agreement. Prior
to granting any such sublicenses, MBC shall provide InterTrust with the name of
the proposed sublicensee and a copy of the proposed sublicense agreement.
InterTrust shall then have thirty (30) days to authorize such proposed
sublicense in which event InterTrust shall provide MBC with a copy of an
agreement containing the terms upon which InterTrust grants such authorization,
that shall be executed by InterTrust, MBC and the sublicensee prior to the
execution of any sublicense agreement hereunder. InterTrust's decision to
authorize or refuse to authorize the sublicensee shall be in InterTrust's sole
discretion, and can be exercised on any basis. If InterTrust fails to authorize
the sublicense, the sublicense agreement shall not take effect.

          (a)  Non-Clearinghouse Sublicenses.  MBC may enter into sublicense
               -----------------------------
     agreements with a maximum of [*] sublicensees, pursuant to which MBC may
     grant such sublicensees some or all of the rights licensed to MBC under
     Sections 5.2 (a)(i), 5.2 (a)(ii) and 5.2 (a)(iii). In addition to other
     terms set forth in this Section 5.3 above, such sublicenses shall be
     subject to the following terms and conditions:

               (i)  Products distributed to, and/or services performed by,
          Persons other than MBC, must be performed solely under MBC Trademarks
          (except where use of InterTrust Trademarks is required herein); and

               (ii) Activities authorized under the sublicense shall be limited
          to: (a) the development of MBC Products or Cooperative Applications,
          which MBC Products or Cooperative Applications shall be solely owned
          by MBC; and (b) the development, manufacturing and marketing of
          Vertical Applications of InterTrust Technology.

                                                                    CONFIDENTIAL

          (b)  Clearinghouse Function Sublicenses. MBC may enter into sublicense
               ----------------------------------
     agreements pursuant to which MBC may authorize performance of some or all
     of the activities licensed to MBC under Section 5.2 (b) by Persons that are
     Authorized Clearinghouse Providers, wherein such Persons have been
     expressly authorized by InterTrust in writing to perform those
     Clearinghouse Functions that form the basis of such sublicense.

     5.4  No Additional Licenses.  MBC understands and acknowledges that
          ----------------------
InterTrust is licensing to MBC only certain limited rights to use InterTrust
Technology, which are further limited in certain ways and with respect to
certain fields of use (such as the performance of Clearinghouse Functions),
subject to the terms and conditions herein.  Thus, notwithstanding the
generality of any other limitations or restrictions contained in this Agreement,
MBC acknowledges and agrees that the licenses that may be granted under Sections
5.2 and 5.3 are the only licenses granted to MBC, and that no other licenses are
granted, expressly, or by implication or estoppel, now or in the future.  In
particular, and without limitation, MBC acknowledges that it: (i) shall have no
license to perform Clearinghouse Functions, or to authorize or assist others to
perform Clearinghouse Functions, other than as expressly set forth in Section
5.2(b); (ii) shall have no license to distribute to any Person any software or
hardware representation of InterTrust Technology other than the Application
Software and/or Authorized Clearinghouse Software as provided herein; and (iii)
shall have no right to enter into sublicenses other than as expressly set forth
in Section 5.3.

     5.5  General Restrictions.  Whether pursuant to Articles 4 or 5 hereof,
          --------------------
and except as specifically provided in this Agreement, MBC covenants that it
shall not during the term of this Agreement or thereafter make, have made, use,
have used, import, lease, sell, transfer, distribute, practice, or have
practiced, make derivative works of, commercially or publicly display or
perform, emulate the functionality of, reverse engineer and/or modify the
InterTrust Technology, the Kernel Technology and/or the Modified Technology. Any
use by MBC of any InterTrust Technology, the Cooperative Applications, the
Kernel Technology and/or Modified Technology outside the scope of the licenses
granted by InterTrust hereunder shall constitute a material breach of this
Agreement.


               ARTICLE 6.  MBC SUPPORT AND ADDITIONAL COVENANTS

     6.1  MBC Support of InterTrust Technology.
          ------------------------------------

          (a)  MBC Use of InterTrust Technology. If MBC exercises its Option in
               --------------------------------
     accordance with Article 5 hereof, in connection with the licenses granted
     to MBC and the other terms hereunder, MBC agrees to develop, produce and
     generally distribute an MBC Product, the Trading Model Cooperative
     Application and/or a Cooperative Application as soon as commercially
     reasonable and practicable, and in any case within twenty-four (24) months
     following the date InterTrust makes available to MBC the System Developer
     Kit 1.0. If MBC has good reason to believe that SDK 1.0 does not provide
     functionality necessary to develop a commercially reasonable trading model
     and such technology is not reasonably otherwise available, the Parties
     will, in good faith, enter into discussions
                                                                    CONFIDENTIAL


                                       17

     concerning possible extensions to such time period. Such time period may be
     extended in a project plan pursuant to Article 3 or by mutual written
     agreement of the Parties, as applicable; provided that: (i) the Parties
                                              -------- ----
     shall have no obligation to agree to any such extension; and (ii) in no
     case shall the total period from first delivery of any InterTrust
     Technology Requirements exceed forty-two (42) months.

          (b)  Compliance with InterTrust Specifications.  In addition to such
               -----------------------------------------
     other restrictions as provided herein, MBC shall not commence the
     distribution, sale or other transfer of any MBC Product and/or Cooperative
     Application, or perform any service using such MBC Product and/or
     Cooperative Application, unless such MBC Product, Cooperative Application
     and/or such service is in Compliance with InterTrust Specifications.
     InterTrust may, from time to time in its sole discretion, modify InterTrust
     Specifications to accommodate progress in InterTrust Technology and related
     product development, and, among other things, to promote architectural and
     functional integrity, standardization, security capability and
     interoperability of InterTrust-based technology, components, products and
     services (a "New Specification"). Such modifications shall be made at such
                  -----------------
     times and involve such modifications as reasonably determined by InterTrust
     in view of applicable prevailing U.S. software industry standards and the
     circumstances motivating such modification. InterTrust shall use
     commercially reasonable efforts to maintain compatability between a New
     Specification and the then preceding Specification, unless considerations
     of security, interoperability, performance, or functionality enhancement
     indicate that such compatibility is not commercially appropriate. To the
     extent InterTrust modifies or revises an InterTrust Specification, or
     releases a new InterTrust Specification, and such New Specification applies
     to any portion of a Cooperative Application and/or MBC Product then being
     used to perform services, and/or being distributed, by MBC (as applicable),
     MBC shall bring such products and/or services into Compliance with such New
     Specification as of the earliest to occur of: (i) the next version,
     release, or production cycle of such Cooperative Application, MBC Product
     and/or the next use thereof to provide any service related thereto (the
     "Next Version"), as earlier applicable, but only to the extent that MBC
      -------------
     receives notice of such New Specification (in accordance with the
     procedures of Section 14.5 hereof) within a reasonably sufficient time of
     such Next Version to accommodate new aspects of such New Specification; and
     (ii) [*] months after MBC receives a released copy of such New
     Specification (pursuant to the notice provision of Section 14.5 hereof).
     Subject to reasonable business circumstances, InterTrust and MBC may agree
     in writing, each in their sole discretion, to a set period of time longer
     than such [*] month period, but no longer than [*] months after MBC
     receives a released copy of such New Specification (pursuant to the notice
     provision of Section 14.5) to accommodate such new aspects of such New
     Specification for certain or all applicable, previously existing MBC
     Products, Cooperative Applications and/or related services. Notwithstanding
     the foregoing, should serious technical interoperability and/or security
     requirements commercially necessitate more prompt action, MBC and
     InterTrust will confer and agree upon the most aggressive, practical
     schedule feasible to reach Compliance with the New Specification, and MBC
     shall take whatever commercially
                                                                    CONFIDENTIAL

     appropriate steps are reasonable and required under the circumstances to
     minimize or eliminate a continuation of such interoperability and/or
     security problems.

          (c)  Compliance Testing. In order to maintain secure interoperability,
               ------------------
     reliability, and system-wide InterTrust integrity, MBC acknowledges that in
     support of InterTrust Technology, InterTrust may implement one or more
     certification programs designed to ensure that licensed products and/or
     associated services (including MBC Products and Cooperative Applications)
     use InterTrust Technology and/or Modified Technology in Compliance with
     InterTrust Specifications (the "Certification Program(s)"). Such
                                     ------------------------
     Certification Programs may, in InterTrust's sole discretion require, for
     example, MBC to: (i) use a suite of test software provided by InterTrust
     for use by MBC to internally test and verify that Cooperative Applications,
     MBC Products and/or associated services are in Compliance with InterTrust
     Specifications; (ii) submit samples of Cooperative Applications and MBC
     Products and any associated programs, parameter data, and any other product
     information that may be technically material to Compliance with InterTrust
     Specifications prior to first use, distribution, sale, or other transfer to
     a Customer other than limited beta testing and pilot model operation as
     specified by InterTrust Specifications, so as to allow InterTrust (or an
     InterTrust delegate) to perform confidential testing ("Certification
                                                            -------------
     Testing"); and/or (iii) provide InterTrust with full and detailed
     -------
     specifications and documentation related to MBC's use of InterTrust
     Technology and Modified Technology for MBC Products, Cooperative
     Applications and any associated services, wherein such specifications and
     documentation are material to such compliance testing and wherein all such
     specifications and documentation shall be certified by an authorized
     representative of MBC. MBC understands and acknowledges that such a
     Certification Program is critical to maintaining the reliability of
     products and services employing InterTrust Technology and/or Modified
     Technology, and in maintaining public confidence in the integrity of
     InterTrust brands as the resource for interoperable electronic commerce.
     MBC shall comply with the Certification Program established by InterTrust
     including, without limitation, provisions relating to delivery of samples,
     correction of non-Compliant products, and applications and associated
     services, and inclusion of certification marks or logos on Cooperative
     Applications, MBC Products and associated services. In connection with any
     Certification Testing, particularly the testing of submitted products
     and/or services, as applicable, InterTrust (or an InterTrust delegate) will
     respond in a prompt manner, and in no event later than one hundred twenty
     (120) days following its receipt of such submitted products, unless
     commercially reasonable factors prolong such testing. Such response shall
     be in the form of: (a) a written approval that the product or service is
     certified (such products and services not being Compliant until such
     certification has been granted); or (b) if not approved, a detailed summary
     of problems and, where feasible, suggested solutions. InterTrust (or an
     InterTrust delegate) will apply the Certification Program, as applicable,
     in a non-discriminatory and consistent manner with respect to similar
     products and/or services. InterTrust's rights under this Section 6.1 shall
     not be affected in any manner by an InterTrust decision not to perform such
     Certification Testing.

                                                                    CONFIDENTIAL

          (d)  Costs of Certification Program.  To defray costs associated with
               ------------------------------
     the performance and administration of the Certification Program, in
     connection with the certification of any MBC Product, Cooperative
     Application, and/or any related service, MBC shall be charged a reasonable
     fee not to exceed industry norms for similar testing activities (and, if
     conducted by InterTrust, the full cost of performing and administering such
     tests, except as set forth below concerning InterTrust payment of a portion
     of such costs). A written estimate of such fee shall be provided to MBC, as
     applicable, as soon as reasonably practical upon MBC's submission of
     samples (or other required material) for testing. Such fees shall be paid
     by MBC, in accordance with standard industry practices, except that
     InterTrust shall pay [*] of such fees for any specific certification test
     (once such fees in the aggregate have exceeded [*] dollars ($US[*]));
     provided that InterTrust's contribution to such fees for such certification
     -------- ----
     tests shall not exceed [*] dollars ($US[*]) in the aggregate.

          (e)  Translation.  MBC agrees that InterTrust shall have the right to
               -----------
     approve all versions of InterTrust Technology, documentation provided by
     MBC concerning MBC Products and Cooperative Applications (including
     Distributable Documentation), legends and Notices required pursuant to
     Section 6.3 hereof and other required notices that may be translated by or
     for MBC into any language other than English.

          (f)  Promotion and Marketing.  The Parties shall jointly participate
               -----------------------
     in, and from time to time (as they may agree) jointly fund, promotional,
     marketing, and sales activities designed to:  (i) increase industry
     awareness of both InterTrust and InterTrust Technology, including, in
     particular, InterTrust, and MBC, MBC Products, Cooperative Applications and
     any services associated therewith; (ii) attract content developers and
     users; (iii) encourage the development of tools and applications that
     employ InterTrust Technology, MBC Products and/or Cooperative Applications;
     (iv) identify potential development and/or licensing partners for
     InterTrust and/or MBC; and (v) encourage broad adoption of InterTrust
     Technology in the industry.  At no time shall MBC make any representation
     or warranty to any Person materially inconsistent with:  (a) InterTrust
     Specifications or Documentation; or (b) the efforts of the Parties with
     respect to promotion, marketing or other matters under this Agreement.

          (g)  Joint Press Releases.  After the Effective Date, the Parties may
               --------------------
     decide, each in their discretion, to make one or more mutually agreeable
     press releases (the "Joint Press Releases").  The content and timing of any
                          --------------------
     Joint Press releases will be subject to mutual agreement of the Parties.
     Any such Joint Press Releases might disclose, for example, the existence of
     this Agreement and the Parties' intentions to develop important electronic
     commerce industry standards and the Trading Model Cooperative Application.
     All other public disclosures with respect to the terms hereof shall be made
     in accordance with Section 9.4.

          (h)  Partnering Commitment.  During the Special Advanced Technology
               ---------------------
     Commitment Period, MBC shall not participate in, assist or promote in any
     manner the development, use or exploitation of any technology or products
     that enable or include any material portion of the Special Advanced
     Technologies (as defined in Exhibit F hereto) at least one embodiment of
     which is originally constructed and developed, or designed, by InterTrust,
     except to the extent such Special Advanced Technologies may be incorporated
     by InterTrust in the InterTrust Technology. However, nothing in the
     foregoing shall be construed to restrict MBC from the development, use or
     exploitation of any technology or the conduct of any business in the
     electronic commerce area, so long as such technology or business
     substantially differs from, and does not include any material portion of,
     the Special Advanced Technologies. If MBC becomes aware that any of its
     planned activities may be subject to the restrictions of this Section
     6.1(h), MBC shall inform InterTrust in writing of the nature of such

---------- * CONFIDENTIAL TREATMENT REQUESTED. CONFIDENTIAL PORTION HAS BEEN
FILED WITH THE SECURITIES AND EXCHANGE COMMISSION.
<PAGE>

planned activity, and, thereafter, the parties shall engage in good faith
discussions having the objective of determining whether such activities are
subject to the restrictions of this Section 6.1(h).  On the other hand, as a
precaution for MBC, InterTrust shall, from time to time, during the Special
Advanced Technology Commitment Period inform MBC of any electronic commerce
business which may become commercially available and is substantially similar to
the Special Advanced Technologies if InterTrust senior management become aware
of such substantially similar electronic commerce business.

Notwithstanding the foregoing and it being understood that (a) a research group
within MBC is currently developing the Active Key Technology (the "Active Key
                                                                   ----------
Group") and certain Independently Developed Technology (as defined below) and
(b) MBC has the opinion that such Active Key Technology was originally
developed from ideas and technology not falling within the Special Advanced
Technologies, MBC shall not be restricted from pursuing the Active Key
Technology and such Independently Developed Technology in the current
development stage thereof. Nonetheless, due to both Parties' concern that such
Active Key Technology and/or such Independently Developed Technology might be
developed in the future in a manner falling within the Special Advanced
Technologies (even if developed independently of and without reference to
InterTrust confidential information), to avoid potential conflicts or
controversy with respect to such development, the Parties agree (1) to set up
the following procedures and (2) that this Section 6.1(h) shall not preclude MBC
from promoting, using or exploiting any such Active Key Technology not based on
InterTrust confidential information and any Independently Developed Technology
so long as MBC abides by the following procedures:

          (A) MBC, prior to the Effective Date, establishes "Chinese Wall"
     procedures, including such procedures set forth on Exhibit G hereto, and
     throughout the duration of the Special Advanced Technology Commitment
     Period actively maintains such procedures, to prevent the exposure of any
     member of the Active Key Group to any Chinese Wall Information (as such
     term is defined in this Section 6.1 (h), below)--such procedures including
     mechanisms established to effectively separate the working activities of
     members of the Active Key Group from all persons and groups within MBC that
     may have knowledge of, or access or exposure to, such Chinese Wall
     Information;

          (B) MBC employees and consultants follow such "Chinese Wall"
     procedures; and

          (C) MBC provides InterTrust with written notice thirty (30) days
     before taking any action to plan or develop any product or service that may
     include any Special Advanced Technologies in any manner whatsoever, whether
     or not based on Independently Developed Technology (or disclosing such
     plan or development to any Person, or entering into discussions aimed at
     allowing any Person to implement or employ such planned or developed
     product or service).

As set forth above, "Independently Developed Technology" means any technology
                     ----------------------------------
developed without access to, including any benefit from, any confidential
Intertrust Technology, Modified Technology and/or any related Confidential or
Top Secret Information (as such terms are defined in Section 9.1 hereof), or any
InterTrust Technology Group information (as defined in Exhibit G) that should be
reasonably maintained as confidential to protect InterTrust's commercial
interests under this Agreement, whether or not such technology embodies or
includes any portion of the Special Advanced Technologies (such technology and
information to be defined collectively as "the Chinese Wall Information").
                                           ----------------------------

If MBC becomes aware of any breach of Sections (A) through (C) immediately above
(a "Compromising Event"), MBC shall immediately take such steps as appropriate
under the circumstances to cease such Compromising Event and to prevent the
reoccurrence of Compromising Events.  MBC shall also, at a minimum:  (W)
immediately inform InterTrust in writing of the occurrence of and
circumstances surrounding a Compromising Event; and (x) investigate the nature
and extent of the contamination caused by the Compromising Event (and report
such findings to InterTrust in writing).  In addition, MBC shall take immediate
and effective

                                      21
<PAGE>

measures to remedy all effects of such Compromising Event. If MBC fails to take
those actions set forth in subparagraphs (A), (C), and/or (w) and (x) of this
Section 6.1(h), or to promptly cure any other breach of this Section 6.1(h) in
the manner specified herein and in Section 12.2 (b) hereof, InterTrust shall be
entitled to immediately terminate this Agreement and to the specific remedies
set forth in Section 11.3, in addition to any other remedies available to
InterTrust under this Agreement, at law or in equity.

Promptly following an MBC notification to InterTrust as provided in subsection
(C) of this Section 6.1(h), InterTrust and MBC shall initiate discussions in
good faith with the objective of determining whether such planned product or
service would include any material portion of the Special Advanced Technologies.
If, as a result of such discussions, InterTrust and MBC agree that such product
or service: (y) would not include any material portion of the Special Advanced
Technologies, then this Section 6.1(h) shall not restrict MBC's pursuit of such
product or service; or (z) would include a material portion of the Special
Advanced Technologies, then MBC shall have the option to promptly give up any
pursuit of such technology or service using a material portion of the Special
Advanced Technologies or to terminate this Agreement upon thirty (30) days prior
written notice to InterTrust and fulfillment of the terms of Section 7.2 (ii),
hereof. If, despite such discussions, the Parties cannot agree and InterTrust
believes that such planned product or service would include any material portion
of the Special Advanced Technologies, InterTrust shall notify MBC in writing of
such belief and allow MBC to make the choice set forth in subparagraph z
immediately above; provided that if MBC has not notified InterTrust of its
                   -------- ----
decision within forty-five (45) days thereafter, InterTrust may immediately
terminate this Agreement and MBC shall be obligated to pay InterTrust the sum
specified in Section 7.2(ii).

     6.2  Customer Agreements.  In addition to other provisions hereof, MBC
          -------------------
shall not distribute any Cooperative Application or MBC Product to any Person
unless MBC shall have first notified and required such Person to execute a
customer agreement:  (i) provided by InterTrust; or (ii) provided by MBC that
(a) has been previously approved in writing by InterTrust and (b) is in
accordance with the terms of this Section 6.2 (the "Customer Agreement").  The
                                                    ------------------
terms of such Customer Agreement relating to InterTrust Technology may be
amended from time to time by InterTrust as may be reasonably necessary to
protect InterTrust's rights hereunder, but solely for subsequent executions of
such Customer Agreement and as herein provided.  The Customer Agreement shall
contain, at minimum and as relevant hereunder, terms that:  (1) notify MBC
customers of the restrictions on MBC's rights with respect to performing
Clearinghouse Functions, granting sublicenses, and otherwise restricting the
rights of such customers with respect to use of the MBC Product or Cooperative
Application, as applicable, especially the InterTrust Technology incorporated
therein; (2) prohibit customers from disassembling, modifying or reverse
engineering any portion of the InterTrust Technology incorporated in the MBC
Product or Cooperative Application; (3) stipulate that such customer has no
right to use the MBC Product or Cooperative Application to engage in or perform
any Clearinghouse Functions whatsoever without InterTrust's express
authorization pursuant to a written license agreement directly between such
customer and InterTrust; (4) prohibit such customer from using the Cooperative
Application or MBC Product to make and/or exploit any commercial product other
than a Vertical Application; (5) provide that the Customer Agreement is to and
for InterTrust's benefit and may be enforced by InterTrust at its discretion;
and (6) contain such other provisions as stipulated herein.  MBC agrees that to
the extent any form of Customer Agreement might be deemed to be unenforceable or
otherwise ineffective in any jurisdiction, MBC shall substitute other forms of
Customer Agreements, or take other actions, as reasonably specified by
InterTrust, including, for example, specifying other generally accepted, legally
effective forms of Customer Agreement, if such exists for a given jurisdiction,
in order to provide InterTrust with legally enforceable protection contemplated
hereunder, including protection against implied licenses and claims of patent
exhaustion relating to InterTrust Technology.  MBC agrees and acknowledges that
MBC's performance of its obligations hereunder is necessary for InterTrust to
adequately protect its Intellectual Property Rights made available hereunder,
and such performance shall constitute a condition precedent to the licenses
granted under Article 5 hereof.

     6.3  Legends and Notices.
          -------------------

          (a)  Product Legends and Notices. MBC shall, in accordance with

     initialization and/or start-up screens of any stand-alone software
     developed by or for MBC using or incorporating InterTrust Technology and/or
     Modified Technology. For purposes of this Agreement, the term "Notices"
     shall include: (i) Intellectual Property Rights, warranty, and disclaimer
     notices; (ii) any symbols or marks stipulating Compliance with InterTrust
     Specifications; (iii) a notice stating that MBC Products and Cooperative
     Applications are "InterTrust Aware" and are being "delivered using
     InterTrust DigiBox and InterTrust Technology" (as such notices may be
     amended by InterTrust from time to time); and (iv) other field of use and
     product notices stipulated by InterTrust, so long as such notices, in the
     reasonable opinion of InterTrust's counsel, assist in protecting InterTrust
     intellectual property and other InterTrust rights under the laws of any

     InterTrust's reputation and goodwill, and of maintaining high, uniformly
     applied standards of quality in connection with MBC's use and distribution
     of products, applications, and services pursuant hereto bearing InterTrust
     Trademarks.  Consequently, to maintain InterTrust's interest in and rights

     agrees that all uses of InterTrust Trademarks as permitted hereunder, and
     the goodwill associated therewith, shall inure solely to the benefit of
     InterTrust.  MBC agrees that it shall not contest the validity of any
     InterTrust Trademarks or registrations thereof or applications with respect
     thereto, or InterTrust's exclusive ownership of the InterTrust Trademarks
     or their associated goodwill.  MBC agrees to make available to InterTrust,
     upon request, copies of MBC's records and such other documentary evidence
     as is/are retained in the ordinary course of business regarding its use of
     the InterTrust Trademarks, and information regarding first use of the

               ------------------
     such standards of quality shall be effective beginning on the date
     InterTrust gives MBC written notice thereof and MBC shall, as soon as
     reasonably practicable thereafter, implement and/or comply with such
     respective portions thereof.

     6.5  MBC's Use of MBC Trademarks on Cooperative Applications and MBC
          ---------------------------------------------------------------

services associated therewith (other than trademark or logos that serve to
generally identify MBC) shall not, concurrently or thereafter, be used to
identify any product other than MBC Products, Cooperative Applications, or other
products or services licensed hereunder, whether by MBC or pursuant to license
or sublicense from MBC.

publicity pursuant to Sections 6.1 (f) or 6.1(g) hereof. InterTrust shall obtain
permission from MBC for any further use of MBC's name and shall comply with MBC
instructions provided in writing by MBC concerning such further use of any MBC

     7.3  Payment Procedure.  Except as otherwise expressly provided in this
          -----------------
Agreement, within [*] ([*]) days after the end of each calendar quarter, MBC
shall pay InterTrust all amounts due and/or payable pursuant to the licenses
granted hereunder, and received during such calendar quarter.  All such payments
shall be made in U.S. dollars ($US) and by wire transfer to such account as
designated by InterTrust in writing.  Concurrently with such royalty payment,
MBC shall provide to InterTrust a written royalty report, certified to be
accurate by an officer of MBC, specifying:  (i) the revenues derived by MBC that
are subject to royalties during each calendar month of such quarter; (ii) the
basis for calculation of the amounts due and payable; and (iii) summaries of
business records employed by MBC to arrive at the information set forth in (i)
and (ii) immediately above.  The manner of calculation of the amounts due and
payable to InterTrust hereunder shall be determined in accordance with
recognized and generally accepted U.S. accounting procedures and principles that
shall be consistently applied to all such payments.

     7.4  Currency.  Gross Commercial Value and all consideration to be paid to
          --------
InterTrust by MBC pursuant to Sections 7.1 (a)(v), 7.1 (a)(vi) or 7.1 (b) in a

quarterly basis (unless otherwise specified by InterTrust in its sole discretion
to be paid in an alternative currency) according to the official rate of
exchange for such currency, as published in the Wall Street Journal (Western
Edition) on its last publication day during each calendar quarter for which such
royalties are due.  If the Wall Street Journal (Western Edition) ceases to
publish such official rate of

                                                                    CONFIDENTIAL

exchange at any time during the term of this Agreement, the official rate of
exchange during any such period of cessation shall be such rate as published by
the Bank of America on the last working day of such calendar quarter for which
such royalties are due.

     7.5  Taxes.  MBC shall pay taxes, including but not limited to withholding
          -----
taxes, imposed by the government of Japan or other jurisdictions outside of the
United States on all fees and royalties payable to InterTrust under this
Agreement.  MBC shall be responsible for payment of all sales, use, value-added
and other taxes, duties and other charges that may fall due with respect to the
transfer to or licensing, reproduction or distribution by MBC of the Cooperative
Applications or the MBC Products, or with respect to MBC's activities in the
Clearinghouse Functions.  InterTrust shall be responsible for payment of all
sales, use, value-added and other taxes that may be imposed by the United States
government on InterTrust with respect to the transfer to or licensing to MBC of
the InterTrust Technology hereunder or with respect to the payments received
hereunder.

     7.6  Interest.  MBC agrees that all sums owed or payable to InterTrust
          --------
hereunder shall bear interest (compounded daily) at the rate of [*] ([*]%) per
month or [*] ([*]) points above the U.S. Prime Rate on an annualized basis as
published at the end of a calendar quarter for which such royalties are due,
whichever is higher, or such lower rate as may be the maximum rate permitted
under applicable U.S. law, from the date upon which payment of the same shall
first become due up to and including the date of payment thereof whether
before or after judgment, and that MBC shall be additionally liable for all
costs and expenses of collection, including, without limitation, reasonable
fees for attorneys and court costs. Notwithstanding the foregoing, such
specified rate of interest shall not excuse or in any way whatsoever be
construed as a waiver of MBC's express obligation to timely provide any and
all payments due to InterTrust hereunder.

     7.7  Audit.  MBC shall maintain at its principal place of business during
          -----
the term of this Agreement and for a period of five (5) years thereafter all
books, records, accounts, and technical materials regarding MBC's activities in

obligations and other material obligations hereunder.  Upon InterTrust's
request, MBC will permit an auditor or agent of InterTrust's choice to examine
and audit, during a reasonable time (but no more than once every six (6)
months), such books, records, accounts, documentation and materials, and take
extracts therefrom or make copies thereof for the purpose of verifying the
correctness of MBC's reported royalty statements and payments provided by MBC or
compliance with the license terms and other material obligations hereunder.  MBC
shall pay any unpaid delinquent amounts within ten (10) days of InterTrust's
request and shall apply any overpayment toward future royalties due and payable
to InterTrust.  To the extent such examination discloses an underpayment greater
than [*] percent ([*]%) of the sums paid to InterTrust by MBC during the
applicable period subject to such audit, and such underpayment is not due to
fraud or errors made by Persons other than MBC (except where such fraud or
errors should have been discovered by MBC in the exercise of reasonable
diligence), MBC shall fully reimburse InterTrust, promptly upon demand, for the
fees and disbursements due the auditor for such audit; provided that such prompt
                                                       -------- ----
payment shall not be in lieu of any other remedies or rights available to
InterTrust hereunder.

                         ARTICLE 9.  CONFIDENTIALITY.

     9.1  InterTrust Technical Information.
          --------------------------------

          (a)  Classification of InterTrust Technology and Documents. InterTrust
               -----------------------------------------------------
     Technology (including Documentation) and other documents provided by
     InterTrust to MBC hereunder shall be marked as one of the following: (i)
     "Unclassified"; (ii) "Confidential"; or (iii) "Top Secret." MBC and its
     employees shall exercise careful judgment when they are in possession of an
     InterTrust document that has not been marked with one of the above-
     described classifications. If any document provided by InterTrust to MBC
     contains any technical information that is not marked as indicated above
     and is not known with certainty to have been either publicly released by
     InterTrust or otherwise classified as "Unclassified" by InterTrust, then
     MBC, its employees and any other Person authorized to possess such
     information shall treat the document as "Confidential," as provided under
     Section 9.1 (b) hereof.

          (b)  Confidential Information.  To the extent that MBC receives from
               ------------------------
     InterTrust under this Agreement any InterTrust Technology or any other
     information or technology that is marked "Confidential" when disclosed in
     written form, or indicated as "Confidential" when disclosed orally
     ("Confidential Information"), MBC shall hold such Confidential Information
       --------------------------
     in strict confidence and in a manner that: (i) is sufficiently secure for
     the character and content of the Confidential Information; and (ii) is not
     less secure than procedures used by MBC to protect its comparably important
     information and technology. MBC shall not, without InterTrust's prior
     written consent, use, disclose, provide or otherwise make available any
     Confidential Information to any Person, except to one or more of MBC's
     permitted sublicensees as authorized under the terms and conditions of this
     Agreement, and their employees. Each of such sublicensees and employees
     shall have a reasonable need to know such Confidential Information, and
     each shall operate under the same restrictions as MBC. Furthermore, in each
     case of disclosure to an employee or authorized sublicensee, access to such
     Confidential Information shall be allowed only to the extent necessary to
     enable MBC or any such authorized sublicensee to exercise its license (or
     sublicense) hereunder and/or as expressly allowed hereunder. MBC and any
     such sublicensees, as the case may be, shall: (a) require their employees
     having access to any portion of Confidential Information to strictly
     maintain its confidentiality; and (b) ensure that each such employee shall
     have executed with MBC and/or an authorized sublicensee (as applicable) a
     written non-disclosure/non-use agreement in the form set forth on Exhibit E
     hereto or as subsequently provided by InterTrust, or MBC's or such
     sublicensee's applicable form agreement which shall effectively and
     comparably bind such employee

                                                                    CONFIDENTIAL

                                       31
<PAGE>


     to the same scope as InterTrust's form agreement, and which MBC's or
     sublicensee's form agreement shall be subject to InterTrust's reasonable
     prior written approval. MBC shall notify InterTrust promptly in writing of
     any unauthorized disclosure or other misuse or misappropriation of any
     portions of the Confidential Information. MBC and any sublicensee (as
     appropriate) shall be fully responsible for any breach of MBC's or
     sublicensees' obligations under this Agreement by any person to whom such
     Confidential Information has been disclosed. Any obligation of MBC with
     respect to Confidential Information pursuant to this Section 9.1(b) shall
     expire thirty-six (36) months after disclosure of such information by
     InterTrust to MBC.

          (c)  Top Secret Information. In order to protect InterTrust's rights,
               ----------------------
     the rights of InterTrust licensees, and the secure interoperability and
     reputation of InterTrust implementations, MBC shall treat any InterTrust
     Technology or other confidential information that is either marked "Top
     Secret" when disclosed in written form, or indicated as "Top Secret" when
     disclosed orally ("Top Secret Information") in a manner not less secure
                        ----------------------
     than MBC's most secret information and, in all events in a manner
     sufficient to reasonably ensure the security of such Top Secret
     Information, given such great sensitivity of such Top Secret Information.
     MBC shall not use, disclose, provide or otherwise make available such Top
     Secret Information to any Person, except to not more than six (6)
     individual employees of MBC, each of whom has a direct need to know such
     information or be exposed to such Top Secret Information (as agreed in each
     case by InterTrust) and then only to the extent necessary for MBC to
     exercise its rights and perform its obligations under this Agreement, and
     none of whom shall receive a disclosure of any such Top Secret Information
     until: (i) such employee becomes bound by personally executing an
     InterTrust Top Secrecy Agreement (in the form set forth in Exhibit E hereto
     or as subsequently provided by InterTrust) covering such information and
     exposure; and (ii) an original executed copy of such agreement is received
     by InterTrust, with return receipt provided to MBC, which such receipt may
     be provided by fax communication if so requested in writing.
     Notwithstanding the foregoing, MBC and MBC employees described above shall
     make no physical embodiments (for example, any reproduction or copy,
     including descriptive notes) whatsoever of Top Secret Information, without
     the prior express written authorization from InterTrust's Chairman of
     Board, President or any other InterTrust Officer designated in a written
     communication to MBC signed by InterTrust's Chairman of the Board (the
     "Designated Officers"), nor shall MBC or such MBC employees disclose any
      -------------------
     Top Secret Information to any Person, except as described in this Section
     9.1 (c). If MBC becomes aware that any Top Secret Information has been
     disclosed or treated other than as set forth in this Section 9.1 (c),
     and/or as specified in a Top Secrecy Agreement, MBC shall immediately
     inform InterTrust of such occurrence and take immediate steps to correct
     such compromise. MBC shall maintain a log of the employees accessing and
     location of all originals and other tangible embodiments of all Top Secret
     Information. MBC shall be fully responsible for any breach by any MBC
     employee of this Agreement related to the unauthorized use or disclosure of
     Top Secret Information.

                                                                    CONFIDENTIAL

     9.2  MBC Technical Information.  To the extent that InterTrust receives MBC
          -------------------------
confidential information that is either marked "confidential" when disclosed in
written form or indicated as "confidential" when disclosed orally, under this
Agreement, InterTrust shall hold said MBC confidential information in confidence
in a manner that is sufficiently secure for the character and content of the
information and under no circumstances shall such confidential information be
held in a manner that is less secure than procedures used by InterTrust in
connection with its comparably important information.  Except as to the
disclosure by MBC to InterTrust of the Modified Technology or such disclosures
inherent in the Certification Testing of MBC Products, Cooperative Applications
and/or any associated services pursuant hereto, and only to the extent expressly
specified by InterTrust Specifications, MBC shall not disclose or otherwise
provide or make available any confidential information of MBC which is directly
related to InterTrust Technology and InterTrust's business activities, without
first acquiring written approval from a Designated Officer of InterTrust.
InterTrust shall not disclose, otherwise provide or make available any MBC
confidential information it has received in any form to any Person who is not
bound by an applicable confidentiality agreement and has a reasonable need to
know such information.  InterTrust agrees to notify MBC promptly in writing of
any unauthorized disclosure of MBC confidential information provided to
InterTrust which may come to the attention of an InterTrust officer.  InterTrust
shall be fully responsible for any breach of InterTrust's obligations under this
Agreement by InterTrust or its employees, consultants, directors, principals, or
Affiliates.  Any obligation of InterTrust to keep MBC information in confidence
shall expire thirty-six (36) months after disclosure of such information by MBC
to InterTrust.

     9.3  Exceptions.  Notwithstanding the provisions of Sections 9.1 (a), 9.1
          ----------
(b) and 9.2 above, and except as to "Top Secret" information as provided in
Section 9.1 (c), the confidentiality restrictions herein shall not apply to
Confidential Information that the recipient thereof can demonstrate:  (i) is or
becomes generally known to the public through no breach of any of these
obligations, as of the date such information becomes so known; (ii) is or shall
have been independently developed by such recipient's employees who had no
access to such information; or (iii) is or shall have been rightfully received,
with no obligation of confidentiality or non-use, by such recipient from any
Person (other than as a result of another Person's breach of an obligation of
confidentiality to InterTrust), as of the date such information is so received.

     9.4  Confidentiality of Agreement and Publicity.  Except as otherwise
          ------------------------------------------
provided in Sections 6.1(h) and 9.3 hereof or as required by law or in
connection with a dispute between the Parties regarding the terms hereof,
neither Party hereto shall at any time, without the prior written consent of the
other Party, disclose the specific details of the terms and conditions of this
Agreement to any Person, other than Affiliates, employees, directors, investors
holding approximately one percent (1%) or more of the outstanding equity shares
and having no reasonably anticipated conflict of interest with the disclosing
party, potential investors who may purchase approximately one percent (1%) or
more of the outstanding equity shares, and/or financial institutions,
professional advisors and/or other consultants having a reasonable need to know
and covered by a confidentiality agreement sufficient in scope to protect the
Parties' rights and interests hereunder.  Notwithstanding the foregoing
provisions of this Section 9.4:  (i) either

                                                                    CONFIDENTIAL

Party may publicly discuss or otherwise disclose that an agreement exists
between the Parties to develop electronic commerce industry standards and the
Trading Model Cooperative Application, but may provide no further material
details as to the specific activities or commitments of the other Party without
the prior written consent of the other Party; and (ii) either Party may make
such disclosures to the extent permitted under this Section 9.4 in order to
comply with its obligations or enforce its rights under this Agreement.

     9.5  Confidentiality of Payments, Audit and Certification Testing.  All
          ------------------------------------------------------------

provided herein, and all information concerning Certification Testing (including
any results thereof), and any and all payment information received by either

Cooperative Application or an associated services being disseminated or used in
commerce is Compliant with InterTrust Specifications shall not be treated as

     11.1 Indemnification.
          ---------------

     hold MBC and its employees, officers and directors (the "MBC Parties")
                                                              -----------
     harmless from any and all liability, judgments, costs, damages, claims,

                                                ------
     the extent awarded by a court of competent jurisdiction or pursuant to a
     settlement as provided hereunder, resulting from controversies or
     litigation asserted by any Person against the MBC Parties arising directly

     this Agreement, or its representations and warranties set forth in Article
     10; and (ii) MBC's use of InterTrust Trademarks pursuant hereto; provided,
                                                                      --------
     however, that, with respect to InterTrust's representations under Section
     -------  ----
     10.2 (b) hereof, this indemnity does not extend to any Claim relating to:
     (1) any Modified Technology or other modifications thereto made by MBC or
     any Person or combinations of the InterTrust Technology with any product,
     technology or service of MBC or of any Person; or (2) the use of any
     InterTrust Technology in any manner inconsistent with InterTrust
     Specifications or Documentation (collectively, the "Indemnification
                                                         ---------------
     Exclusions").
     ----------

          (b)  MBC Indemnification. MBC shall indemnify and hold InterTrust, its
               -------------------
     employees, officers and directors (the "InterTrust Parties") harmless from
                                             ------------------
     any and all Claims or portions thereof to the extent awarded by a court of
     competent jurisdiction or pursuant to a settlement as provided hereunder,
     resulting from controversies or litigation asserted by any Person against
     the InterTrust Parties arising directly or indirectly from: (i) MBC's or
     any of its sublicensees' breach of any of any obligations, representations
     or warranties hereunder; (ii) InterTrust's use of MBC Trademarks pursuant
     hereto; (iii) the design, manufacture, use, distribution and/or disposition
     of Modified Technology, Cooperative Applications or MBC Products, or
     performance of any service associated therewith, that would not have
     otherwise arisen out of MBC's use of the InterTrust Technology alone,
     except to the extent MBC is indemnified by InterTrust under Section 11.1
     (a) hereof; (iv) any Claim relating to the Indemnification Exclusions; and
     (v) any exercise by MBC or any of its sublicensees of the licenses
     hereunder that would not have otherwise arisen out of MBC's use of the
     InterTrust Technology alone, except to the extent MBC is indemnified by
     InterTrust under Section 11.1 (a) hereof.

          (c)  Third Party Claims.  In case any Claim is brought by a third
               ------------------
     party for which Claim indemnification is provided hereunder: (i) the
     indemnified Party shall provide prompt written notice thereof to the Party
     obligated to indemnify such Claim; and (ii) the indemnifying Party shall,
     upon the demand and at the option of the indemnified Party, assume the
     defense thereof (at the expense of the indemnifying Party) within thirty
     (30) days or at least ten (10) days prior to the time a response is due in
     such case, whichever occurs first, or, alternatively upon the demand and at
     the option of the indemnified Party, pay to such Party all reasonable costs
     and expenses, including

                                                                    CONFIDENTIAL

                                       36
<PAGE>


     reasonable attorneys' fees, incurred by such Party in defending itself. The
     Parties shall cooperate reasonably with each other in the defense of any
     Claim, including making available (under seal if desired, and if allowed)
     all records reasonably necessary to the defense of such Claim, and the
     indemnified Party shall have the right to join and participate actively in
     the indemnifying Party's defense of the Claim. Notwithstanding the
     foregoing (and any other section of this Agreement), it is understood and
     acknowledged that InterTrust need not under any circumstance provide Top
     Secret Information related to the security capabilities of InterTrust
     Technology to any Person. Each Party shall be entitled to reasonable
     approval of the settlement of any Claim to be entered into by the other
     Party. Without limiting the foregoing, if as a result of such defense or
     settlement, an injunction is entered or threatened or an agreement is
     reached prohibiting MBC from using any portion of the InterTrust
     Technology, as MBC's sole remedy for such prohibition of such continued
     use, InterTrust may at InterTrust's sole option either: (a) [*] for MBC to
     [*] and [*] in accordance with the terms hereof such portion (at MBC's
     expense, should MBC desire to so continue to [*] such portion); (b) [*] or
     [*] of the [*] or Licensed Rights, as the case may be, so as to make it
     [*]; or (3) if options (a) and (b) are not [*] in InterTrust's
     determination, terminate the licenses granted hereunder as to such portion.
     In addition, as to any such portion, InterTrust may, at any time after such
     Claim is brought or threatened, notify MBC that InterTrust is electing one
     of the options (a), (b) or (c) as to such portion to be effective
     immediately or at such time specified by InterTrust subject in (a) to MBC's
     agreement.

     11.2  Cumulative Remedies.  Except as expressly provided herein to the
           -------------------
contrary, no remedy made available to a Party by any of the provisions of this
Agreement is intended to be exclusive of any other remedy, and each and every
remedy shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute or
otherwise.

     11.3  Equitable Remedies.  Each Party agrees that it may be impossible or
           ------------------
inadequate to measure and calculate a Party's damages from any breach of the
covenants set forth in Sections 4.2, 5.4, 5.5, 6.1(b), 6.1(h), 6.2, 6.3, 6.4,
6.5, 7.7, 12.3 and 14.7 and Articles 8 and 9 hereof. Accordingly, each Party
agrees that if it or any of such Party's employees, licensees, divisions or
Affiliates or agents thereof breach or threaten a breach or anticipatory
repudiation of any of such provisions, in addition to any other right or remedy
available, the other Party shall be entitled: (i) to obtain an injunction
against the breaching Party and such Party's employees, licensees, divisions,
Affiliates, and/or agents thereof, from a court of competent jurisdiction
restraining such breach or threatened breach; and (ii) to specific performance
of any such provision of this Agreement. In addition, MBC agrees that, in the
event MBC breaches any of its obligations under Section 6.1(h), InterTrust shall
be entitled, in addition to any other remedies available at law or in equity, to
extend the Special Advanced Technology Commitment Period for an additional
twenty-four (24) month period (measured from the later of the date such breach
is admitted by MBC or established by a final judgment pursuant to

                                                                    CONFIDENTIAL


---------- * CONFIDENTIAL TREATMENT REQUESTED. CONFIDENTIAL PORTION HAS BEEN

which all appeal rights have been exhausted), and MBC hereby irrevocably agrees
to an award of specific performance of such provision in InterTrust's favor.

     11.4  EXCLUSION OF DAMAGES.  EXCEPT AS SET FORTH IN THE IMMEDIATELY
           --------------------
FOLLOWING SENTENCE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY, ITS
AFFILIATES, DIVISIONS, CUSTOMERS, EMPLOYEES, OR ANY OTHER PERSONS, FOR ANY LOST
PROFITS, INCIDENTAL, INDIRECT, OR CONSEQUENTIAL DAMAGES, ARISING OUT OF THE
BREACH OF THIS AGREEMENT OTHER THAN UNDER SECTION 6.1(h) AND ARTICLES 8 AND 9.
NOTWITHSTANDING THE IMMEDIATELY PRECEDING SENTENCE, A PARTY SHALL BE LIABLE TO
THE OTHER PARTY FOR ALL DAMAGES, INCLUDING LOST PROFITS, INCIDENTAL, INDIRECT,
OR CONSEQUENTIAL DAMAGES SUFFERED OR INCURRED BY THE OTHER PARTY IN THE
FOLLOWING CIRCUMSTANCES: (i) THE MISAPPROPRIATION OF TRADE SECRETS OF THE
DAMAGED PARTY BY THE LIABLE PARTY, ITS DIRECTORS, OFFICERS, EMPLOYEES,
CONSULTANTS OR AGENTS; (ii) THE GROSS NEGLIGENCE OF THE LIABLE PARTY, ITS
DIRECTORS, OFFICERS, EMPLOYEES, CONSULTANTS OR AGENTS; (iii) THE WILLFUL
MISCONDUCT OR MATERIAL BREACH OF THIS AGREEMENT IN BAD FAITH BY THE LIABLE
PARTY, ITS DIRECTORS, OFFICERS, EMPLOYEES, CONSULTANTS OR AGENTS; OR (iv) THE
BREACH OF SECTION 6.1(h) AND ARTICLES 8 OR 9 HEREOF. IN ANY DISPUTE AS TO
DAMAGES, THE LIABLE PARTY SHALL BE REQUIRED TO PROVE THE ABSENCE OF MATERIAL
NEGLIGENCE, WILLFUL MISCONDUCT AND/OR INTENTIONAL MATERIAL BREACH OF THIS
AGREEMENT IN BAD FAITH, AS THE CASE MAY BE, REFERRED TO IN THE IMMEDIATELY
PRECEDING SENTENCE.


                      ARTICLE 12.  TERM AND TERMINATION.

     12.1  Agreement.  This Agreement shall commence on the Effective Date and
           ---------
shall continue for a period of twenty-five (25) years therefrom unless and until
terminated earlier pursuant to Section 12.2 below. At the end of such twenty-
five (25) year term, this Agreement shall automatically renew for subsequent one
(1) year period unless and until a Party notifies the other in writing of its
intent not to renew this Agreement prior to sixty (60) days before the beginning
of the next such one (1) year period.

     12.2  Events of Termination.  This Agreement, the licenses granted
           ---------------------
hereunder, and/or the Trading Model Cooperative Project Plan and all Cooperative
Application Project Plans shall be subject to termination upon the occurrence of
any of the following events and such other provisions hereof expressly so
stating (each, an "Event of Termination"):

     in its sole discretion, to initiate a

                                                                    CONFIDENTIAL

     termination procedure under this Agreement by written notice (sent in
     accordance with the provisions of Section 14.5 hereof) describing with
     reasonable specificity the nature of the default and requesting that such
     default be cured, wherein such termination notice shall automatically
     result in termination unless: (i) within sixty (60) calendar days of
     receiving such written notice of such default (the "Cure Period"), the
                                                         -----------
     defaulting Party (or such sublicensee) remedies the default; or (ii) in the
     case of a default that cannot with due diligence be cured within the Cure
     Period, the defaulting Party or such sublicensee institutes, by the date
     upon which one half of the Cure Period shall have expired, steps necessary
     to remedy the default and thereafter employs best efforts to diligently
     prosecute the same to completion. Notwithstanding the foregoing, the Cure
     Period associated with MBC's breach of its payment obligations in
     accordance with Sections 7.1 and 7.2 shall be five (5) business days.
     Notwithstanding any of the foregoing, InterTrust shall have the right both
     to immediately terminate this Agreement and to obtain injunctive relief in
     the event of any: (a) unauthorized disclosure of Top Secret Information or
     intentional, material unauthorized use of the InterTrust Technology or the
     Licensed Rights; and/or (b) willful, material unauthorized disclosure of
     Confidential Information, except as expressly provided for by this
     Agreement.

          (c)  By a Party, effective immediately upon written notice to the
     other Party, in the event of: (i) the filing by the other Party of a
     petition in bankruptcy or insolvency; (ii) the appointment of a receiver
     for all or substantially all of its property relevant to the business
     activities under this Agreement; (iii) the making by the other Party of any

     under this Agreement; or (iv) the institution of any proceedings for the
     liquidation or winding up of the other Party's business or for the
     termination of its corporate charter, if any such proceeding is not
     dismissed within one hundred and twenty (120) days of institution;

          (d) Upon written notice to MBC, InterTrust may immediately terminate

     Section 5.1; (iii) MBC does not develop the Trading Model Cooperative
     Application or an MBC Product implementing the Trading Model within forty-
     two (42) months from the date InterTrust first delivers any InterTrust
     Technology Requirements to MBC; (iv) MBC fails to terminate any sublicense
     pursuant to which the sublicensee thereunder materially defaults its
     obligations under this Agreement for a period of sixty (60) days after the
     date of written notice thereof from InterTrust or MBC, whichever is
     earlier; (v) MBC breaches any of its obligations under Section 6.1(h); or
     (vi) MBC fails to perform one or more of its material obligations under
     this Agreement on two or more occasions over a [*] year period. Upon thirty
     (30) days prior written notice to MBC, InterTrust may terminate this
     Agreement in its sole discretion if MBC notifies InterTrust, as provided in
     Section 6.1(h), that it plans to develop or employ a product or service
     within the Special Advanced Technologies employing Independently Developed
     Technology, or if it fails to so notify InterTrust as provided hereunder.

                                                                    CONFIDENTIAL

          (e)  A Party to a Trading Model Cooperative Project Plan or a
     Cooperative Application Project Plan shall have the right to terminate such
     plan if the other Party thereto materially breaches any of its material
     obligations thereunder.

     12.3 Effect of Termination. Upon termination hereof: (i) all licenses
          ---------------------
granted hereunder, all sublicenses granted by MBC pursuant to Section 5.3, and
all cooperative development efforts then being conducted pursuant to the Trading
Model Cooperative Project Plan and any Cooperative Application Project Plan
shall automatically terminate; (ii) InterTrust shall have the right to retain
all sums already paid by MBC (and all MBC sublicensees) hereunder, and MBC (and
all MBC sublicensees) shall pay to InterTrust all sums accrued but unpaid within
thirty (30) days thereafter; and (iii) MBC (and all MBC sublicensees) shall
immediately discontinue its use of InterTrust Technology and/or Modified
Technology, and discontinue any service associated therewith (including
termination of distribution of Cooperative Applications and MBC Products
incorporating or using InterTrust Technology and/or Modified Technology);
provided, however, that all licenses properly granted to end-users pursuant to
--------  -------  ----
the then-existing Customer Agreements shall continue in full force and effect in
accordance with the terms thereof (provided that such licenses shall in no event
provide any rights with respect to Clearinghouse Functions). Each Party shall
deliver to the other Party within ten (10) days from the date of termination of
this Agreement all copies of all materials protected as Confidential Information
or Top Secret Information under this Agreement. Return of Confidential
Information shall be by commercially secure means as reasonably specified by the
receiving Party. Return of Top Secret Information shall be made, at InterTrust's
option as designated by a Designated Officer by written authorization to MBC:
(a) by physical and secure pickup at MBC's offices by an InterTrust officer; (b)
by physical and secure delivery to InterTrust's offices in Japan (upon
establishment of such offices); and (c) as otherwise may be determined by
InterTrust as commercially reasonable. Such delivery shall be during normal
business hours and in each instance to the hands of an InterTrust officer who
audits and countersigns such delivery. Each Party shall return within said ten
(10) days to the other Party all copies of all confidential materials of such
other Party, including all physical embodiments of Confidential Information in
the possession or control of the other Party, its sublicensees, their employees,
consultants, or other agents. Within one (1) month after the termination of this
Agreement, each Party will certify in writing to the other Party that, to the
best of its knowledge, all such materials and tangible embodiments have been
delivered to the other Party.

     12.4 Survival. The respective rights and obligations of InterTrust and
          --------
MBC under the provisions of Sections 4.2(ii), 5.5, 6.1(h), 6.5, 7.2, 7.7 (but
only for a period of four years), 8.1, 8.2, 8.3, 12.3, this Section 12.4, and
Articles 9, 11, 13 and 14 hereof shall survive expiration or termination of this
Agreement.

                              ARTICLE 13. EXPORT.

     13.1 Compliance with Law and Export Controls. The Parties shall at all
          ---------------------------------------
times comply with all applicable U.S., Japanese and foreign federal, state, and
local laws, rules and regulations relating to the execution, delivery and
performance of this Agreement and to the

                                                                    CONFIDENTIAL

                                       40

InterTrust Technology Requirements and Modified Technology. Additionally, MBC
acknowledges that one or more aspects of the InterTrust Technology Requirements,
and/or Documentation and Assistance with respect thereto, is likely to be
subject to the export control laws, regulations and requirements of the United
States and other jurisdictions. InterTrust shall use reasonable efforts at
InterTrust's expense, and MBC shall at InterTrust's request reasonably assist
InterTrust at MBC's expense, to obtain any license or other approval that may be
required for InterTrust's initial export of the InterTrust Technology
Requirements and/or Documentation or information relating thereto from the
United States to Japan and MBC understands and agrees that certain modifications
to InterTrust Technology Requirements and/or Documentation may be required by
U.S. law and/or regulatory process and agrees to the implementation of such
modification by InterTrust, as necessary. In the event that InterTrust is unable
to comply with its obligations hereunder due to an inability to obtain any such
license or other approval, such inability to obtain approval shall be considered
a force majeure event under Section 14.12. MBC shall, at MBC's expense (subject
to InterTrust's right of approval), comply with all applicable laws (including
applicable U.S. export control laws and regulations) and obtain all necessary
governmental consents and approvals to: (i) further distribute the MBC Products
and Cooperative Applications (as well as other technology as expressly permitted
hereunder) that contain any part of the InterTrust Technology Requirements or
Modified Technology in accordance herewith; and (ii) further export and re-
export the InterTrust Technology Requirements and/or Modified Technology. MBC
shall: (a) promptly deliver, as available, to InterTrust documentation
confirming to InterTrust's reasonable satisfaction MBC's compliance with MBC's
responsibilities under this Section 13.1; and (b) obtain such consents and
approvals from appropriate governmental entities as InterTrust's counsel may
reasonably determine to be necessary (as relates to InterTrust Technology
Requirements or Modified Technology) for such further distribution, exportation
or re-exportation.

     13.2 Failure to Obtain Export Approval. In the event MBC exercises its
          ---------------------------------
Option and, thereafter, InterTrust has not yet received and further fails to
obtain approval from relevant authorities ("Export Approval") to export SDK 1.0
                                            ---------------
to MBC within six (6) months after InterTrust's first commercial shipment of its
FCS SDK 1.0 product to a Person not subject to such Export Approval (the
"Conversion Date"), MBC shall receive a warrant (the "Warrant") to receive that
----------------                                      -------
number of shares of InterTrust stock (the "Warrant Shares") determined by the
                                           --------------
following mathematical formula:

                Number of Shares = License Fee/ Price Per Share

Where "License Fee" is equal to the license fee paid to InterTrust pursuant to
Section 7.1(a)(i) hereof and,

               "Price Per Share" = Valuation/Outstanding Shares

Where "Valuation" is a number that is the greater of: (a) $US100,000,000; and
(b) one half (1/2) of the then-current value of InterTrust as determined in good
faith by InterTrust's Board of Directors as of the Conversion Date, and
"Outstanding Shares" is equal to the total number of InterTrust shares issued
and outstanding as of the Conversion Date. The Warrant Shares shall

                                                                    CONFIDENTIAL

                                       41
<PAGE>


be shares of InterTrust common stock and/or preferred stock as determined by
InterTrust's Board of Directors in good faith.

The Warrant shall be a written agreement with InterTrust containing terms and
provisions as reasonably established by InterTrust in view of, among other
things, the class of InterTrust stock to which such Warrant Shares belong and
InterTrust's extant agreements. Such Warrant shall not be convertable by MBC for
six (6) months after the Conversion Date and at any time during such six (6)
month period the Warrant shall terminate if InterTrust obtains Export Approval
and, notwithstanding any termination hereof, delivers or offers to deliver SDK
1.0 to MBC on the terms provided herein. If at any time subsequent to the
Conversion of such Warrant InterTrust obtains Export Approval and makes such SDK
1.0 available to MBC, and MBC accepts delivery of such SDK 1.0, InterTrust shall
have the right, exercisable in its discretion, to reacquire all such shares from
MBC by tendering to MBC such reasonable amount of interest on the sums then
tendered by MBC to InterTrust pursuant to Section 7.1(a) hereof as determined by
InterTrust's Board of Directors in good faith and as shall be set forth in the
Warrant Agreement.

whether like or unlike the foregoing, beyond the reasonable control of a Party
hereto, such Party is unable to perform in whole or in part its obligations set
forth in this Agreement, then such Party shall be relieved of those obligations
to the extent it is so unable to perform, and such inability to perform, so
caused, shall not make such Party liable to the other Party. Notwithstanding the
foregoing, in the event any such cause delays either Party's performance of any
of its material obligations under this Agreement, the other Party may suspend
its performance under this Agreement for the period such delay continues. Except
in the case of application of this Section 14.12 due to the provisions of
Article 13 hereof, this Agreement may be terminated by notice by the Party not
seeking excuse from performance, if such event shall prevent performance for
longer than one hundred and twenty (120) days. The Party subject to an event of

Company shall so advise all Holders, (2) the Lead Series A Investor shall be
entitled to include Registrable Securities in such underwriting up to the
Maximum Number, (3) if the Lead Series A Investor elects to include in such
underwriting a number of its Registrable Securities which is less than the
Maximum Number (the "Series A Portion"), the Initiating Holders of Series A
Registrable Securities (if different than the Lead Series A Investor) and those
Holders of Series A Registrable Securities (other than the Lead Series A
Investor) joining in the Request shall be entitled to include in such
underwriting their pro-rata share of Series A Registrable Securities up to that
number of shares equal to the difference between the Maximum Number and the
Series A Portion and (4) if the Holders of Series A Registrable Securities
(including the Lead Series A Investor) elect to include in such underwriting a
number of their Registrable Securities which is less than the Maximum Number,
the Holders of Other Series Registrable Securities joining in the Request shall
be entitled to include in such underwriting their pro-rata share of Other Series
Registrable Securities up to that number of shares equal to the difference
between the Maximum Number and the total number of shares that the Holders of
Series A Registrable Securities (including the Lead Series A Investor) elect to
include in such underwriting. For purposes of the preceding sentence, (x) a
Holder's "pro-rata share of Series A Registrable Securities" shall mean the
quotient obtained by dividing the number of Series A Registrable Securities held
by such Holder by the sum of all of the Series A Registrable Securities held by
the Initiating Holders (if different than the Lead Series A Investor) and those
Holders of Series A Registrable Securities (other than the Lead Series A
Investor) joining in the Request and (y) a Holder's "pro-rata share of the Other
Series Registrable Securities" shall mean the quotient obtained by dividing the
number of Other Series Registrable Securities held by such Holder by the sum of
all of the Other Series Registrable Securities held by the Initiating Holders
and those Holders of Other Series Registrable Securities joining in the Request.
No Registrable Securities excluded from the underwriting by reason of the
Managing Underwriter's marketing limitation shall be included in such
underwriting. To facilitate the allocation of shares in accordance with the
above provisions, the Company or the underwriters may round the number of shares
allocated to any Holder to the nearest 100 shares. If any Holder declines to
participate upon review of the terms of the underwriting, such Holder may elect
to withdraw therefrom by written notice to the Company, the Managing Underwriter
and the Initiating Holders. The Registrable Securities and/or other securities
so withdrawn shall also be withdrawn from registration, and such Registrable
Securities shall not be transferred in a public distribution prior to 180 days
after the effective date of such registration, or such other shorter period of
time as the underwriters may require. If the underwriter has not limited the
number of Registrable Securities to be underwritten, or if Holders have elected
to include less than the Maximum Number in such underwriting, the Company may
include securities for its own account (or for the account of other
stockholders) in such registration if the Managing Underwriter so agrees and if
the number of Registrable Securities that would otherwise have been included in
such registration and underwriting will not thereby be limited.

                    (iii) The Company shall pay the Expenses of Registration for
one (1) registration requested pursuant to this Section 4.1(b).  Notwithstanding
the immediately preceding sentence, in the event that the Company is obligated
to effect an additional registration pursuant to the proviso to Section
4.1(b)(2)(D), then the Company shall pay the Expenses of Registration for two
(2) registrations requested pursuant to this Section 4.1(b).

                    --------------------

                    (i)   Notice of Registration. If (but without any obligation
                          ----------------------
to do so) at any time after the Initial Public Offering the Company proposes to
register any of its Common Stock or other securities under the Act in connection
with the public offering of such securities solely for cash (other than a
registration relating either to the sale of securities to participants in a
Company stock option, stock purchase or similar plan or to an SEC Rule 145
transaction, or a registration on Form S-8, Form S-4 or any successors to such
forms, the Company shall, at such time, promptly give each Holder written notice
of such registration. Upon the written request of any Holder given within twenty
(20) days from receipt of such notice by the Company in accordance with Section
8.6, the Company shall, subject to the provisions of Section 4.1(c)(ii) and
4.1(d), cause to be registered under the Act all of the Registrable Securities
that each such Holder has requested to be registered.

                    (ii)  Underwriting Requirements. In connection with any
                          -------------------------
offering pursuant to this Section 4.1(c), the Company shall not be required to
include any of the Holders' securities in such underwriting unless they accept
the terms of the underwriting as agreed upon between the Company and the
underwriters selected by it, and then only in such quantity as will not, in the
opinion of the underwriters, adversely affect the success of the offering by the
Company. If the total amount of securities, including Registrable Securities,
requested by stockholders to be included in such offering exceeds the amount of
securities sold other than by the Company that the underwriters reasonably
believe would not adversely affect the success of the offering, then the Company
shall be required to include in the offering only that number of such
securities, including Registrable Securities, which the underwriters believe
will not adversely affect the success of the offering (the securities so
included to be apportioned first to the Company, then second pro rata among the
selling Holders of Series A Registrable Securities according to the total amount
of Series A Registrable Securities owned by each selling Holder, then third pro
rata among the selling Holders of Other Series Registrable Securities according
to the total amount of Other Series Registrable Securities owned by each selling
Holder and then fourth to all other selling stockholders, or in such other
proportions as shall mutually be agreed to by all such parties), it being
understood that all Registrable Securities may be excluded from the registration
on this basis. For any selling stockholder which is a holder of Registrable
Securities and which is a partnership or corporation, the partners, retired
partners and stockholders of such holder, or the estates and family members of
any such partners and retired partners and any trusts for the benefit of any of
the foregoing persons shall be deemed to be a single "selling stockholder," and
any pro rata reduction with respect to such "selling stockholder" shall be based
upon the aggregate amount of Registrable Securities owned by all entities and
individuals included in such "selling stockholder," as defined in this sentence.

                    (iii) The Company shall pay the Expenses of Registration for
two (2) registrations requested pursuant to this Section 4.1(c).

               (d)  Furnish Information. It shall be a condition precedent to
                    -------------------
the obligations of the Company to take any action pursuant to this Section 4.1
with respect to the Registrable Securities of any selling Holder that such
Holder shall furnish to the Company such

information regarding itself, the Registrable Securities held by it, and the
intended method of disposition of such securities as shall be required to effect
the registration of such Holder's Registrable Securities.

               (e)  Expenses of Registration. The term "Expenses of
                    ------------------------
Registration" means all expenses other than underwriting discounts and
commissions incurred in connection with registrations, filings or qualifications
pursuant to this Section 4.1, including (without limitation), all registration,
filing and qualification fees, printers and accounting fees, fees and
disbursements of counsel for the Company. Expenses of Registration does not
include the fees and disbursements of counsel for the selling Holders.

               (f)  No Delay of Registration. No Holder shall have any right to
                    ------------------------
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 4.1.

               (g)  Indemnification. In the event any Registrable Securities are
                    ---------------
included in a registration statement under this Section 4.1:

                    (i)   To the extent permitted by law, the Company will
indemnify and hold harmless each Holder of Series B Registrable Securities, any
underwriter (as defined in the Act) for such Holder and each person, if any, who
controls such Holder or underwriter within the meaning of the Act or the
Securities Exchange Act of 1934, as amended (the "1934 Act"), against any
losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Act, the 1934 Act or other federal or state law,
insofar as such losses, claims, damages, or liabilities (or actions in respect
thereof) that arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation"): (i) any untrue statement
of a material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation by the
Company of the Act, the 1934 Act, any state securities law or any rule or
regulation promulgated under the Act, the 1934 Act or any state securities law;
and the Company will pay, as incurred, to each such Holder, underwriter or
controlling person, to the extent (and only to the extent) that such losses,
claims, damages, or liabilities arise out of a Violation, any legal or other
expenses reasonably incurred by any person intended to be indemnified pursuant
to this Section 4.1(g) in connection with investigating or defending any such
loss, claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this Section 4.1(g) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company, nor shall the Company
be liable in any such case for any such loss, claim, damage, liability, or
action to the extent that it arises out of or is based upon a Violation which
occurs in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by any such Holder,
underwriter or controlling person.

<PAGE>

                    (ii)  To the extent permitted by law, each selling Holder of
Series B Registrable Securities will indemnify and hold harmless the Company,
each of its directors, each of its officers who has signed the registration
statement, each person, if any, who controls the Company within the meaning of
the Act, any underwriter, any other Holder selling securities in such
registration statement and any controlling person of any such underwriter or
other Holder, against any losses, claims, damages, or liabilities (joint or
several) to which any of the foregoing persons may become subject, under the
Act, the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereto) arise out of or are
based upon any Violation, in each case to the extent (and only to the extent)
that such Violation occurs in reliance upon and in conformity with information
furnished by such Holder expressly for use in connection with such registration;
and each such Holder will pay, as incurred, any legal or other expenses
reasonably incurred by any person intended to be indemnified pursuant to this
Section 4.1(g)(ii), in connection with investigating or defending any such loss,
claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this Section 4.1(g)(ii) shall not apply to amounts paid
in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Holder. Nothing contained in
this Section 4.1(g)(ii) is intended to preclude the underwriters in any offering
from requiring broader indemnities from the Holders participating in such
offering.

                    (iii) Promptly after receipt by an indemnified party under
this Section 4.1 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 4.1, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain separate counsel of its own, with the reasonable fees
and expenses to be paid by the indemnifying party, if representation of such
indemnified party by the counsel retained by the indemnifying party would be
inappropriate due to actual or potential differing interests between such
indemnified party and any other party represented by such counsel in such
proceeding; provided further that the indemnifying party shall not be
responsible for the fees and expenses of more than one separate counsel for all
indemnified parties.  The failure to deliver written notice to the indemnifying
party within a reasonable time of the commencement of any such action, if
prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
4.1 (to the extent of such prejudicial effect), but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section 4.1.

                    (iv)  No indemnifying party, in the defense of any claim
arising out of a Violation shall, except with the consent of each indemnified
party, consent to entry of any judgment or enter into any settlement which does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release from all liability in respect
to such claim or litigation and, in the event the terms of such judgment or
settlement include any term other than the payment by the indemnifying party of
money

damages, the indemnifying party shall not so consent or enter into such a
settlement without the consent of each indemnified party (which will not be
unreasonably withheld) whether or not the terms thereof include such a release.

                    (v)   The obligations of the Company and Holders under this
Section 4.1 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 4.1, and otherwise.

               (h)  Form S-3 Registration. In case the Company shall receive
                    ---------------------
from any Holder or Holders a written request that the Company effect a
registration on Form S-3 and any related qualification or compliance with
respect to all or a part of the Registrable Securities owned by such Holder or
Holders, the Company will:

                    (i)   Promptly give written notice of the proposed
registration, and any related qualification or compliance, to all other Holders;
and

                    (ii)  As soon as practicable, effect such registration and
all such qualifications and compliances as may be so requested and as would
permit or facilitate the sale and distribution of all or such portion of such
Holder's or Holders' Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any other
Holder or Holders joining in such request as are specified in a written request
given within twenty (20) days after receipt of such written notice from the
Company in accordance with Section 8.6; provided, however, that the Company
shall not be obligated to effect any such registration, qualification or
compliance, pursuant to this Section 4.1(h):

                          (1)  If Form S-3 is not available for such offering by
the Holders;

                          (2)  Unless the Holders, together with the holders of
any other securities of the Company entitled to inclusion in such registration,
propose to sell either (x) Registrable Securities having an aggregate price to
the public (net of any underwriters' discounts and commissions) in excess of
$2,000,000; or (y) not less than 15% of the Registrable Securities then
outstanding;

                          (3)  If the Company shall furnish to the Holders a
certificate signed by the Chief Executive Officer of the Company stating that in
the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company for such Form S-3 registration to be
effected at such time, in which event the Company shall have the right to defer
the filing of the Form S-3 registration statement for a period of not more than
120 days after receipt of the request of the Holder or Holders under this
Section 4.1(h); provided, however, that the Company shall not utilize this right
more than once in any twelve (12) month period;

                          (4)  If the Company has completed its Initial Public
Offering within 180 days of the Company's receipt of the request for the Form S-
3 registration; or

                                 CONFIDENTIAL

                          (5)  In any particular jurisdiction in which the
Company would be required to qualify to do business or to execute a general
consent to service of process in effecting such registration, qualification or
compliance.

                    (iii) Notwithstanding anything to the contrary herein, the
Company shall not be obligated to effect more than two (2) registrations
pursuant to this Section 4.1(h), and no more than one (1) such registration in
any twelve (12) month period.

                    (iv)  Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders. The Company shall pay the Expenses of
Registration for two (2) registrations requested pursuant to this Section
4.1(h). Registrations effected pursuant to this Section 4.1(h) shall not be
counted as registrations effected pursuant to Sections 4.1 (b) or (c).

               (i)  Assignment of Registration Rights.  The rights to cause the
                    ---------------------------------
Company to register Registrable Securities pursuant to this Section 4.1 may only
be assigned by a Holder to a transferee who acquires all of such Holder's
shares, provided the Company is, within a reasonable time after such transfer,
furnished with written notice of the name and address of such transferee; and
provided, further, that such assignment shall be effective only if immediately
following such transfer the further disposition of such securities by the
transferee or assignee is restricted under the Act.

               (j)  "Market Stand-Off" Agreement. Each Purchaser hereby agrees
                     ---------------------------
that during the 180 day period following the effective date of each of (i) a
registration statement of the Company filed under the Act in connection with the
Initial Public Offering and (ii) the registration statement filed under the Act
with respect to an underwritten offering of Common Stock (or securities which
are immediately convertible at the option of the holder or convertible within
twelve (12) months from the date of issuance into Common Stock) after the
Initial Public Offering, it shall not sell, offer to sell, or otherwise transfer
or dispose of any capital stock of the Company held by it at any time during
such period except to the extent such Purchaser participates as a selling
stockholder in such registrations. To enforce the foregoing covenant, the
Company may impose stop-transfer instructions with respect to the Registrable
Securities of the Purchaser (and the shares or securities of every other person
subject to the foregoing restriction) until the end of such period. Each Holder
agrees to execute the form of such market stand-off agreement as may be
reasonably requested by the underwriters.

               (k)  Termination or Amendment of Registration Rights. The
                    -----------------------------------------------
registration rights granted under this Section 4.1 may be terminated, waived or
amended with the written consent of the Company and the Holders of 66% of the
Series B Registrable Securities then outstanding. In addition, no Holder of
Series B Registrable Securities shall be entitled to exercise any right provided
for in this Agreement (a) after four (4) years following the closing of the
Initial Public Offering or (b) at such time following the Initial Public
Offering and for so long as such Holder may sell all of such Holder's Series B
Registrable Securities in any ninety (90) day period pursuant to Rule 144(k) (or
such successor rule as may be adopted).

                                 CONFIDENTIAL

               (l)  Registration Rights of Holders of Series A Registrable
                    ------------------------------------------------------
Securities. The rights granted to the Holders of Series B Registrable Securities
----------
in Sections 4.1(b), 4.1(c) and 4.1(h) of this Agreement to have Series B
Registrable Securities owned by them registered shall be subject to the rights
granted to the Holders of Series A Registrable Securities in Sections 4.1(b),
4.1(c) and 4.1(h) of the Series A Preferred Stock Agreement to have Series A
Registrable Securities owned by them registered.

          4.2  Restriction on Transfer; Right of First Refusal.
               -----------------------------------------------

               (a)  Restriction on Transfer. Neither any Purchaser nor any
                    -----------------------
transferee of any Purchaser shall sell or transfer in any manner any shares of
Series B Preferred Stock purchased hereunder (or any shares of the Class A
Voting Common Stock into which such shares of Series B Preferred Stock may be
converted) to any person or entity engaged in, or reasonably anticipated by the
Company to become engaged in, the business of providing electronic commerce
solutions or related technology (a "Restricted Party"). A Purchaser or any
transferee of any Purchaser may request that the Company waive the restriction
on the sale or transfer of shares described in the preceding sentence to a
Restricted Party as to a particular, proposed sale or transfer, but the Company
shall have no obligation to waive such restriction on the sale or transfer of
any such shares to any Restricted Party.

               (b)  Right of First Refusal. In the event, at any time after the
                    ----------------------
date of this Agreement, any Purchaser or its transferee desires to sell or
transfer in any manner any shares of Series B Preferred Stock purchased
hereunder (or any shares of the Class A Voting Common Stock into which such
shares of Series B Preferred Stock have been converted) to a person or entity
which is not a Restricted Party, it shall first offer such shares for sale to
the Company at substantially the same price, and upon substantially the same
terms (or terms as similar as reasonably possible) upon which it is proposing or
is to dispose of such shares; provided that a Purchaser may transfer all or part
of its shares of Series B Preferred Stock (or any shares of the Class A Voting
Common Stock into which such shares of Series B Preferred Stock have been
converted) to a corporation or other entity which is not a Restricted Party and
not less than fifty-one (51%) percent of whose outstanding capital stock or
other equity interests is owned beneficially and of record by the Purchaser
without first making such offer to the Company. Said right of first refusal
shall be provided to the Company for a period of fifteen (15) days following
receipt by the Company of written notice (the "Proposed Transfer Notice") by the
Purchaser of the terms and conditions of said proposed sale or transfer and the
name, address and phone number of each proposed buyer or transferee. The Company
may exercise such right of first refusal as to all, or some portion which is
less than all, of the shares proposed to be transferred by notifying the
Purchaser in writing within such fifteen day period, and paying such Purchaser
within thirty (30) days following receipt by the Company of the Proposed
Transfer Notice the relevant consideration therefor. If the Company and its
assigns do not complete the purchase of shares of Series B Preferred Stock (or
any shares of the Class A Voting Common Stock into which such shares of Series B
Preferred Stock have been converted) identified in the Proposed Transfer Notice
within thirty (30) days following receipt by the Company of the Proposed
Transfer Notice, the Purchaser may sell or transfer such shares in accordance
with the terms and conditions set forth in the Proposed Transfer Notice to the
person or entity identified

                                 CONFIDENTIAL

                                      -18-

in the Proposed Transfer Notice. If the Purchaser desires to sell or transfer in
any manner such shares either (i) upon terms and conditions which are different
than those specified in the Proposed Transfer Notice or to a person or entity
other than the person or entity identified in the Proposed Transfer Notice or
(ii) more than sixty (60) days after the Company's receipt of the Proposed
Transfer Notice, then the Purchaser shall comply with the provisions of this
Section 4.2(b) again prior to effecting any such sale or transfer.

               (c)  Assignment.  The Company may assign the rights granted to it
                    ----------
pursuant to this Section 4.2 in whole or in part to any stockholder or
stockholders of the Company or other persons or organizations.

               (d)  Restrictions Binding on Transferees. All transferees of
                    -----------------------------------
shares purchased pursuant to this Agreement, shares of the Class A Voting Common
Stock issued upon the conversion of such shares or any interest therein will
receive and hold such shares or interest subject to the provisions of this
Section 4.2.

               (e)  Termination of Right of First Refusal. The right of first
                    -------------------------------------
refusal granted the Company in Section 4.2(b) shall terminate upon consummation
of the Initial Public Offering, with such termination retroactive to the
effectiveness of the registration statement relating to the Initial Public
Offering.

          4.3  Mergers and Other Extraordinary Transactions.
               --------------------------------------------

               (a)  Agreement.  Each Purchaser shall either (i) take all actions
                    ---------
necessary to vote all shares of the Series B Preferred Stock (and all shares of
the Class A Voting Common Stock into which such shares of Series B Preferred
Stock may be converted) owned or held of record by such Purchaser at any annual
or special meeting of the Company (or by written consent in lieu of such
meeting) held for the approval of any merger, consolidation or sale or exchange
of all or substantially all of the Company's assets which has been approved by
the Board of Directors in favor of any such merger, consolidation or sale or
exchange of all or substantially all of the Company's assets and all
transactions and other matters incident thereto or (ii) refrain from taking any
action with respect to any merger, consolidation or sale or exchange of all or
substantially all of the Company's assets which has been approved by each of the
Board of Directors and the majority of the outstanding stock of the Company
entitled to vote thereon which prevents, restricts or otherwise inhibits such
merger, consolidation or sale or exchange of all or substantially all of the
Company's assets from being accorded pooling accounting treatment.  Without
limiting the generality of clause (ii) of the preceding sentence, the Purchaser
agrees to refrain from asserting any appraisal rights that it may have as a
consequence of any transaction described in the immediately preceding sentence

     Set forth below are exceptions to the representations and warranties of the
Company made in Sections 2 and 8.7 of the Agreement.  All disclosures and
exceptions set forth below modify all of the Company's representations and
warranties and a disclosure in one section of this Schedule shall modify the

 2.2      Capitalization and Voting Rights.
          --------------------------------

     The Company has granted the following preemptive rights with respect to its
     capital stock:

     1. Four of the Company's eight outstanding Common Stock Purchase Warrants
        provide their respective holders with a right of first offer with
        respect to certain issuances by the Company of its equity securities.
        The Company has made a written request that such holders waive their
        right of first offer with respect to the transactions contemplated by
        this Agreement. All of such holders have waived their rights of first
        offer with respect to the transactions contemplated by this Agreement.

     2. The Company has granted certain holders of shares of Series A Preferred
        Stock a right of first offer with respect to certain sales by the
        Company of certain of its securities in Section 4.2 of the Series A
        Preferred Stock Agreement. The Company has made a written request that
        such holders waive their right of first offer with respect to the
        transactions contemplated by this Agreement. All but one of such holders
        have waived their rights of first offer with respect to the transactions
        contemplated by this Agreement; the holder which did to waive did not
        exercise its right of first offer within the time period prescribed by
        the Series A Preferred Stock.

 2.08     Litigation.
          ----------

     1. On February 28, 1996 the Company received a letter from E-Data Corp.
        drawing the Company's attention to Patent No. 4,528,643 and alleging the
        need for the Company to obtain a license with respect to such patent.
        Upon review of the materials submitted with the February 28, 1996
        letter, the Company believes that the claims made therein are based upon
        incorrect assumptions and premature and the Company so advised E-Data
        Corp. by letter dated March 12, 1996. The Company has received no
        substantial response.

     2. On June 26, 1996 the Company received a letter from Dorsey & Whitney
        LLP, counsel to Digi International, Inc. ("DI"), drawing the Company's
        attention to U.S. Trademark Reg. No. 1,666,495 of DI for DIGIBOARD (R)
        and, among other things, requesting that the Company cease any planned
        use of the name DIGIBOX. The

Mitsubishi Corporation
3-1 Marunouchi 2-Chome, Chiyoda-Ku,
TOKYO 100-86, Japan

Ladies and Gentlemen:

          We have acted as counsel to InterTrust Technologies Corporation, a
Delaware corporation (the "Company"), in connection with the sale by the Company
of 116,685 shares of Series B Preferred Stock, $.001 par value, of the Company
(the "Series B Preferred Shares") pursuant to the Series B Preferred Stock
Purchase Agreement dated as of October 7, 1996 (the "Purchase Agreement")
between the Company and Mitsubishi Corporation, a Japanese corporation (the
"Purchaser").  This opinion is being delivered pursuant to Section 6.6 of the
Purchase Agreement.  Capitalized terms used and not otherwise defined herein
shall have the respective meanings assigned to such terms in the Purchase
Agreement.

          In connection with this opinion, we have examined and relied upon
originals or copies, certified or otherwise identified to our satisfaction, of
the Purchase Agreement and such other documents (including, without limitation,
corporate records of the Company and certificates of public officials) as we
have deemed necessary or appropriate as the basis for the opinions set forth
below.  In our examination we have assumed the genuineness of all signatures,
the legacy capacity of natural persons, the authenticity of all documents
submitted to us as originals, and the conformity to authentic original documents
of all documents submitted to us as certified or photostatic copies.  In
rendering the opinions set forth below, we have relied solely on certificates
from public officials as to the matters stated in such certificates.  As to
questions of fact material to this opinion, we have relied upon representations
(including without limitation, representations set forth in the Purchase
Agreement) and certificates of the Company and its officers and of public
officials, and we have not inquired of third parties or searched the records or
files of any governmental authority.

          Further, we have assumed that:  (a) the Purchaser is duly organized
and validly existing under the laws of its jurisdiction of incorporation and has
full power, authority and legal right to enter into and perform its obligations
under the Purchase Agreement; (b) the Purchase Agreement has been duly
authorized, executed and delivered by the Purchaser, (c) the Purchase Agreement
is the legal, valid and binding obligation of the Purchaser, enforceable against
the Purchaser in accordance with in terms; and (d) the Purchaser has received,
or will receive by the time required, and will, to the extent required by
applicable law, maintain in full force and effect,
<PAGE>

Mitsubishi Corporation

Page 2

all governmental approvals required for the due execution, delivery and
performance by the Purchaser of the Purchase Agreement, and that such
execution, delivery and performance by the Purchaser does nor conflict with
any provision of applicable law.

          Members of this firm are admitted to the bar of the District of
Columbia.  We express no opinion as to the laws of any jurisdiction other than
(i) the present Federal laws of the United States of America and the District of
Columbia, and to the extent required by the opinions expressed below, the
General Corporation Law of the State of Delaware, and our opinion is limited and
applies only insofar as such laws may be concerned.

          Based upon and subject to the foregoing, and subject to the other
qualifications, exceptions, limitations and assumptions set forth below, we are
of the opinion that:

          1.  The Company is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation. The Company
has the requisite corporate power and authority to execute, deliver and
perform the Purchase Agreement, to issue, sell and deliver the Series B
Preferred Shares and to issue and deliver the shares of Class A Voting Common
Stock, $.001 par value per share, of the Company issuable upon conversion of
the Series B Preferred Shares (the " Conversion Shares").

          2.  The Purchase Agreement has been duly authorized, executed and
delivered by the Company and constitutes the legal, valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms.

          3.  The execution and delivery by the Company of the Purchase
Agreement, the performance by the Company of its obligations thereunder, the
sale of the Series B Preferred Shares to the Purchaser and, upon conversion
thereof in accordance with the Certificate of Designations, Preferences and
Rights, the issuance and delivery of the Conversion Shares will not violate
any provision of the Certificate of Designations, Preferences and Rights, the
Restated Certificate of Incorporation or By-laws of the Company.

          4.  To our knowledge, there are no actions, suits, proceedings or
investigations pending or threatened against the Company before any court or
governmental agency that, either any individual case or in the aggregate,
could reasonably be expected to result in any material adverse change in the
business or financial condition of the Company and none that questions the
validity of the Agreement or any action to be taken in connection therewith.

          5.  The Series B Preferred Shares and the Conversion Shares have
been duly authorized. Upon issuance and delivery of the Series B Preferred
Shares, against payment of the consideration provided in the Purchase
Agreement, the Series B Preferred Shares will be validly issued and fully paid
and nonassessable. The issuance and delivery of the Conversion Shares, upon
conversion of the Series B Preferred Shares in accordance with the Certificate
of Designations, Preferences and Rights, have been duly authorized by all
requisite corporate action, the Conversion Shares have been duly reserved for
issuance upon conversion of the Series B Preferred Shares in accordance with
the Certificate of Designations, Preferences and
<PAGE>

Mitsubishi Corporation

Page 3

Rights and, when so issued, will be duly authorized, validly issued, fully
paid and nonassessable. Neither the issuance, sale or delivery of the Series B
Preferred Shares nor the issuance or delivery of the Conversion Shares is
subject to any preemptive right of stockholders of the Company arising under
law or the Certificate of Designations, Preferences and Rights, the Restated
Certificate of Incorporation or Bylaws of the Company or, to our knowledge,
any contractual right of first refusal or other right which has not heretofore
either been waived or not exercised by the holder thereof.

          6.  Assuming the accuracy of the representations and warranties of
the Purchaser set forth in Section 3 of the Purchase Agreement, no
registration or filing by the Company with, and no consent or approval of, or
other action by any Federal, state or other governmental agency or
instrumentality is or will be necessary for the valid execution and delivery
by the Company of the Purchase Agreement, the sale of the Series B Preferred
Shares, or, upon conversion thereof in accordance with the Certificate of
Designations, Preferences and Rights, the issuance and delivery of the
Conversion Shares, other than the filing pursuant to Section 25102(f) of the
California Corporate Securities Law of 1968, as amended, and the rules
thereunder.

          7.  Assuming the accuracy of the representations and warranties of
the Purchaser set forth in Section 3 of the Purchase Agreement, the sale of
the Series B Preferred Shares to the Purchaser on the Closing Date, under the
circumstances contemplated by the Purchase Agreement, is exempt from the
registration requirements of the Securities Act of 1933, as amended, and the
issuance and delivery of the Conversion Shares, upon conversion of such Series
B Preferred Shares in accordance with the Certificate of Designations,
Preferences and Rights, will be exempt from such registration requirements.

          The opinions set forth above are subject to the following limitations
and qualifications:

          (A)  We express no opinion as to (i) compliance with applicable
antifraud provisions of Federal or state securities laws or, except to the
extent set forth in paragraph 6, any matters arising under or relating to
state securities laws or "blue sky" laws; (ii) the validity, binding effect or
enforceability of any provision of the Purchase Agreement relating to
indemnification, contribution or exculpation in connection with violations of
any securities laws or statutory duties or public policy, or in connection
with willful, reckless or criminal acts or gross negligence of the indemnified
or exculpated party or the party to receive contribution; and (iii) the
enforceability of any provision or term of the Purchase Agreement which may be
found by a court to be rendered unenforceable due to the indefinite or
incomplete nature of such provision or term.

          (B)  Our opinion with respect to enforceability see forth in
paragraph 2 above is subject to (i) applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' rights
generally; (ii) general equitable principles (regardless of whether such,
principles are considered in a proceeding at law or in equity); and (iii) the
effect of judicial decisions which have held that certain provisions are
unenforceable when their enforcement

would violate the implied covenant of good faith and fair dealing, or would be
commercially unreasonable, or where their breach is not material. We have
assumed with your permission in providing our opinion with respect to
enforceability set forth in paragraph 2 above that the laws of the District of
Columbia are the same as the laws of the State of California (the laws
governing the construction of the Purchase Agreement).

          This opinion is rendered solely for your benefit in connection with
the transaction referred to in the first paragraph of this option, and may not
be relied upon in any manner or for any purpose by any other person or entity
without our prior written consent.  This opinion is based on our knowledge of
the law and the facts as of the date hereof, and we undertake no obligation to
update or supplement this opinion after the date hereof.

                    --------------------------------------


As a general matter, the Trading Model Cooperative Project Plan will: (i) set
forth terms and conditions (such as development milestones, cost estimates,
development fees, etc.) for the development of the Trading Model Cooperative
Application; and (ii) outline and embody a staged approach for the entire
development process, from project planning through quality and acceptance
testing of generated code.

It is contemplated that Trading Model Cooperative Project Plan will incorporate,
as agreed to by the Parties, the following terms:

          Trading Model Cooperative Application conforms to the specifications
          therefor and to InterTrust Specifications;

     .    an estimate of the costs for the Trading Model project, a development
          plan containing budgets and milestones and a specification of a
          formula for calculating any consideration that the MBC may pay to
          InterTrust, including any development fees consistent with Section 3.3
          hereof; and

     .    provisions concerning ownership of Intellectual Property Rights and
          other rights relating to the Trading Model Cooperative Application, if
          terms and conditions related to such rights differ in any way from
          this Agreement.

Furthermore, it is contemplated that the Trading Model Cooperative Project Plan
will comprise the development stages as set forth below:

     .    description of the Trading Model project and formulation of the
          desired behavior of the Trading Model Cooperative Application(s) from
