     3.3  Training, Assistance and Technical Support. Subject to the terms of
          ------------------------------------------
this Agreement, InterTrust agrees to provide the following training, assistance
and technical support to SSG for a period of thirty-six (36) months from the
Effective Date (the "Support Period"):
                     --------------

          (a) Training and Assistance. In order to assist SSG in its evaluation
              -----------------------
     and/or use of InterTrust Technology products, the InterTrust Dedicated
     Personnel (as defined in Section 3.3(d)) shall provide to SSG account
     management, at no further cost to SSG and subject to applicable terms and
     conditions of this Agreement, training, consulting, relationship
     assistance, project management, and other assistance directly related
     thereto ("Assistance") [*]. Such Dedicated Personnel shall provide up to
               ----------
     two thousand (2,000) hours per annum of such Assistance, as described in
     Section 3.3(d) hereof, so long as SSG is entitled to favorable treatment
     under this Article 3. InterTrust shall further provide, as may be requested
     by SSG, up to one hundred (100) hours of Assistance by persons other than
     the Dedicated Personnel for general training and support purposes. All such
     Assistance will be measured based upon InterTrust's man-hours expended
     (excluding time expended to travel or perform administrative tasks related
     to the relationship), and shall be subject to reasonable agreement between
     the Parties on scheduling, availability of resources and related matters.
     As appropriate, such Assistance may include certain training sessions to
     which certain other InterTrust licensees (in addition to SSG) may be
     invited to attend. In such an event, InterTrust will notify SSG in advance
     of such other participants. SSG shall be responsible for all expenses
     incurred by SSG's personnel in traveling to and attending any training and
     support meetings. In the event InterTrust's personnel travel from
     InterTrust's facilities (upon InterTrust's and SSG's mutual agreement), SSG
     shall reimburse InterTrust for all actual and reasonable travel, living and
     out-of-pocket expenses incurred by InterTrust's personnel based on SSG's
     standard policies and procedures for reimbursement of its independent
     contractors and its own employees.

          (b) Correction of Material Defects. In addition to InterTrust's own
              ------------------------------
     ongoing quality assurance efforts, InterTrust shall use reasonable prompt
     efforts in accordance with reasonable U.S. software industry practices, at
     InterTrust's expense and subject to InterTrust's standard support policies
     as relevant, to correct Material Defects, or otherwise reasonably adjust
     InterTrust Technology to mitigate Material Defects, identified by SSG to
     InterTrust in a writing describing the alleged Material Defects in detail.
     InterTrust shall have no obligation to: (i) investigate or correct any
     Material Defects at any site other than an InterTrust facility, except that
     InterTrust will visit SSG's facilities as may be required in the reasonable
     judgment of both InterTrust and SSG to investigate Material Defects that
     severely and critically degrade operation of InterTrust Technology and
     cannot otherwise be diagnosed by SSG; (ii) communicate on the subject of
     Material Defects with any Person other than SSG; or (iii) correct any
     Material Defects that have been properly identified by SSG but that cannot
     be reliably reproduced. Notwithstanding the foregoing, SSG shall reimburse
     InterTrust for all actual and reasonable travel, living and out-of-pocket
     expenses incurred by InterTrust's personnel (based on SSG's standard
     policies and procedures for reimbursement of its independent contractors
     and its own employees) for any site visit referenced in this Section 3.3(b)
     after the second such site visit per calendar year.

          (c) Status Meetings. To assist the Parties in sharing information,
              ---------------
     and coordinating and evaluating their efforts relating to InterTrust
     Technology and their mutual technical and business objectives, following
     the Effective Date the Parties shall meet from time to time to discuss,
     among other things: (i) InterTrust's progress in development of the
     InterTrust Technology; (ii) implementation of such technology by SSG; (iii)
     feedback concerning Assistance provided to SSG and product development and
     marketing progress by SSG; and (iv) other issues concerning the Parties'
     mutual technical and business objectives (the "Status Meetings"). Such
                                                    ---------------
     Status Meetings shall: (1) be attended at a minimum by each Party's
     Relationship Manager and Technical Project Manager (as defined in Section
     3.3(d)); and (2) take place not less frequently than once every two (2)
     months until January 1, 1998, and, thereafter, as may be agreed by the
     Parties.

          (d) Dedicated Personnel. InterTrust and SSG will each appoint a
              -------------------
     relationship manager, to coordinate its activities pursuant to this Section
     3.3 and Article 4 ("Relationship Manager"), and a technical project
                         --------------------
     manager, to coordinate and provide the Assistance set forth in Section
     3.3(a) and 3.3(b), 3.3(b) ("Technical Project Manager") (collectively, the
                                 -------------------------
     "Dedicated Personnel"). Not less than one-half (1/2) of such InterTrust
      -------------------
     Relationship Manager's and such InterTrust Technical Project Manager's
     working time shall be devoted exclusively to providing services and
     Assistance for SSG as set forth herein, if reasonably required by the
     circumstances or reasonably requested by SSG, so long as SSG is entitled to
     most favored treatment under Section 3.2(b) hereof.

     3.4  Additional Assistance. During the Support Period, additional
          ---------------------
Assistance may be made available by InterTrust to SSG beyond the one hundred
(100) hours allocated under Section 3.3(a) hereunder. To the extent SSG
requests, and InterTrust decides (in the exercise of its sole discretion) to
provide, such additional Assistance, and SSG continues to be entitled to most
favored treatment under Section 3.2(b) hereof, SSG shall pay to InterTrust [*].
After the Support Period, any further support or Assistance desired by SSG shall
be subject to InterTrust's standard support policies and support packages, and
any fees charged to SSG in this regard shall be [*]. To the extent InterTrust
requires all of its Core Partners or customers who have license rights and
obligations comparable to SSG, as may be applicable, to maintain a basic level
of support, SSG shall maintain such basic support policy in the same manner as
is generally provided by InterTrust Core Partners or customers.

               ARTICLE 4. COOPERATIVE PROJECTS AND APPLICATIONS.

     4.1  Cooperative Projects. From time to time during the term of this
          --------------------
Agreement, the Parties may discuss the terms and conditions under which they may
cooperate with respect to Cooperative Applications, including discussing the
types of projects and formulating the terms of a project plan (a "Cooperative
                                                                  -----------

respect to one or more Cooperative Applications (which may include the
applications set forth in Section 4.2 below), but agreement to such terms and
conditions shall be in the reasonable discretion of each Party, and any failure
to agree shall not constitute a breach of this Agreement. The Parties' intent

respect to information to be contained within a Cooperative Application Project
Plan is described in Exhibit E hereto, as may be amended from time to time upon
the mutual agreement of the Parties (each in the exercise of its sole
discretion). Exhibit E further includes other information appropriate to
represent any agreement between the Parties related to any such project plan.
The provisions of this Agreement shall govern the Parties' actions in
implementing any Cooperative Application Project Plan to which the Parties
agree, except to the extent that such provisions herein are inconsistent with
explicit provisions of that specific Cooperative Application Project Plan, in
which event the provision of such Cooperative Application Project Plan shall
govern. A breach of a Cooperative Application Project Plan, other than those
terms relating to Intellectual Property Rights, ownership or licenses thereof
granted by InterTrust, shall not constitute a material breach of this Agreement,
unless expressly stipulated to the contrary in such Cooperative Application
Project Plan.

     4.2  Potential Cooperative Applications. The Parties have, to date, had
          ----------------------------------
preliminary discussions concerning two potential Cooperative Applications:

          (i)  an information delivery model, tentatively denominated
"Electronic Express(TM)," supporting security for, and the auditing, validation,
and/or authentication of electronically delivered information (e.g., contracts
or other documents, multimedia, video transmissions, etc.), and further
including (a) a third party service provider that receives and/or can access
information that may be used to identify or validate at least a portion of the
delivered information for the purpose of verifying or reconstructing (in whole
or in part) facts relating to delivery of the information (e.g., the
transmitting party, transmitted content, and/or the receipt, identity and/or use
by the intended recipient of transmitted content) and/or (b) the distribution of
content in software containers to recipients employing secure, interoperable,
auditing and control means that make accessible to sending and/or receiving
parties explicit event validation and/or one or more facts for potential
identification purposes, wherein: (1) such containers have specified Rules and
Controls that manage use of the content and (2) one or more potential uses of
the content are controlled, at least in part, by one or more Rules and Controls
specified by a sending party; and

          (ii) an application, tentatively denominated "Publish America(TM),"
that enables individual users and organizations to become cyberspace publishers
through the packaging of digital content in Secure Containers utilizing one or
more material portions of any Special Advanced Technologies.

     Clearinghouse Functions solely under the SSG Trademarks, and solely in
     cases in which SSG performs and controls such Clearinghouse Functions in
     Compliance with InterTrust Specifications. Such Clearinghouse Functions may
     be performed solely: (i) to service Rights User Nodes, each such node
     having been provided by (1) an SSG Product and/or Cooperative Application,
     and solely in connection with such SSG Product and/or Cooperative
     Application, or (2) such Compliant products for which InterTrust has
     expressly granted a license to have Authorized Clearinghouse Providers

     products and applications employing InterTrust Technology and/or Modified
     Technology, and in related documentation and marketing materials.

     5.2  Sublicense Rights. In accordance with the terms of this Section 5.2,
          -----------------
SSG may enter into sublicense agreements pursuant to which SSG may authorize
certain other entities to perform portions of the actions licensed to SSG under
Sections 5.1(a) and 5.1(b) hereof. Sublicense agreements relating to SSG's
rights under: (i) Sections 5.1(a)(i), 5.1(a)(ii), 5.1(a)(iii) and 5.1(a)(iv)
shall be governed by Section 5.2(a), below; and (ii) Section 5.1(b) shall be
governed by Section 5.2(b), below. All sublicensees must enter into a written
sublicense agreement with SSG, the form and content of which agreement (or
agreements, as appropriate) are fully consistent with the provisions of this
Section 5.2 and have been previously approved by InterTrust in writing (such
approval not to be withheld unless such form agreements do not reasonably
protect InterTrust's rights as set forth in this Agreement or its Intellectual
Property Rights). Upon approval, each sublicense form shall be attached as an
Exhibit hereto and may be used by SSG as appropriate under the circumstances,
unless and until InterTrust reasonably requires that one or more approved
sublicense forms be modified, to accommodate, for example, modified provisions
or additional provisions reasonable under the circumstances. Such sublicense
form agreement shall, at minimum, require each sublicensee to agree in writing:
(a) to be subject to SSG's obligations under this Agreement; (b) to perform
obligations identical to the obligations of SSG under Sections 5.1, 5.3, 5.4,
6.1, 6.2, 6.3, 6.4, 6.5 (to the extent any sublicensee marks may be used in
connection with products), 6.6 and 10.2, and Articles 7, 8, 11, 12, 13, 15 and
16 of this Agreement to the extent of their activities under the sublicense, and
(c) to agree to provisions substantially as set forth in Sections 8.4 and 10.2.
In addition, each sublicensee shall enter into a written agreement with
InterTrust, in the form of a certification form to be attached as an Exhibit to
the sublicense agreement, pursuant to which such sublicensee agrees that
InterTrust shall have the right to enforce the terms of the sublicense agreement
between SSG and such sublicensee. Prior to granting any such sublicense, SSG
shall provide InterTrust with the name of the proposed sublicensee and a
certification that the proposed sublicense agreement includes all of the
provisions contained in the approved sublicense form. Where the proposed
sublicensee is not a SSG and/or SOFTBANK Affiliate, InterTrust shall have thirty
(30) days to authorize such proposed sublicensee. InterTrust's decision to
authorize or refuse to authorize a proposed sublicensee that is not a SSG and/or
SOFTBANK Affiliate shall be in InterTrust's sole discretion, and can be
exercised on any basis. If InterTrust fails to authorize the sublicensee, the
sublicense agreement shall not take effect. Any sublicense granted to an
Affiliate of SSG or SOFTBANK shall remain effective only so long as such
sublicensee remains an Affiliate of SSG or SOFTBANK. SSG shall guarantee and
remain liable to InterTrust for all sublicensees' performance of such
obligations. Sublicensees shall have no further right to sublicense any right
received. SSG agrees and acknowledges that SSG'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 granting of other licenses under Article 5 hereof.

          (a) Non-Clearinghouse Sublicenses. SSG may enter into sublicense
              -----------------------------
     agreements pursuant to which SSG may grant sublicensees some or all of the
     rights licensed to SSG under Sections 5.1(a)(i), 5.1(a)(ii), 5.1(a)(iii),
     5.1(a)(iv) and 5.1(c). In addition to other terms set forth in this Section
     5.2 above, such sublicenses shall be subject to the following terms and
     conditions:

               (i)    SSG shall grant sublicenses only to SOFTBANK or its
          Affiliates (and only while SSG is a SOFTBANK Affiliate);

               (ii)   Products distributed to, and/or services performed by,
          Persons other than SSG must be performed and branded solely under SSG
          Trademarks or, as applicable, other SSG Affiliate or SOFTBANK
          Affiliate trademarks as set forth herein (except where use of
          InterTrust Trademarks is required herein), but in the case of a SSG or
          SOFTBANK Affiliate, only for so long as such SSG or SOFTBANK Affiliate
          remains such an Affiliate;

               (iii)  Activities authorized under the sublicense shall be
          limited to the development of SSG Products or Cooperative
          Applications.

          (b)  Clearinghouse Function Sublicenses. SSG may enter into sublicense
               ----------------------------------
     agreements pursuant to which SSG may authorize performance of some or all
     of the activities licensed to SSG under Section 5.1(b) by any Person, but
     solely to perform Clearinghouse Functions on behalf of SSG, and solely
     under SSG Trademarks or, as applicable hereunder, any other SSG or SOFTBANK
     Affiliate trademarks as set forth herein and in accordance with Section
     5.1(b) hereof.

     5.3  No Additional Licenses. SSG understands and acknowledges that
          ----------------------
InterTrust is licensing to SSG only certain limited rights to use InterTrust
Technology (including performing Clearinghouse Functions and sublicensing
certain rights granted SSG) as described herein. Thus, notwithstanding the
generality of any other provision herein, SSG acknowledges and agrees that the
licenses granted under Sections 5.1 and 5.2 are the only licenses granted to
SSG, and that no other licenses are granted, expressly, or by implication or
estoppel, now or in the future. All rights not expressly granted to SSG under
this Agreement are reserved and retained by InterTrust.

     5.4  General Restrictions. SSG covenants that it shall not: (i) during
          --------------------
the term of this Agreement, reverse engineer any technology that has been
supplied to SSG in Object Code form only, or emulate the functionality of,
and/or modify any portion of the Core Technology; or (ii) after the term of this
Agreement, use or exploit the InterTrust Technology for any purpose whatsoever.
Any use by SSG of any portion of the InterTrust Technology and/or Modified
Technology outside the scope of the licenses granted by InterTrust hereunder
shall constitute a material breach of this Agreement.

          (a) SSG Use of InterTrust Technology. In accordance with the
              --------------------------------
     licenses granted to SSG and the other terms hereunder, SSG agrees to
     develop, produce, and generally distribute, or use for commercial purposes,
     a SSG Product and/or a Cooperative Application as soon as commercially
     reasonable and practicable, and in any case within eighteen (18) months
     following the date InterTrust makes available to SSG the System Developer
     Kit 1.0 in beta format. Such time period shall be extended by any period in
     which: (i) there exists a Material Defect in the InterTrust Technology that
     materially impedes SSG's development efforts as relevant, but only from the
     date that SSG documents such defect as provided in Section 3.3(b) hereof to
     the date InterTrust has reasonably corrected or removed such Material
     Defect as provided hereunder; or (ii) InterTrust materially fails to
     provide any of the support services required in Section 3.3 (other than
     Section 3.3(b)) and such material failure actually impedes SSG's
     development efforts, as relevant, but only to the extent of any delay
     reasonably and solely attributable to such material failure.

          (b) Compliance with InterTrust Specifications. SSG shall not commence
              -----------------------------------------
     the distribution, sale or other transfer of any specific SSG Product or
     Cooperative Application, or perform any service directly relating to such
     products or applications, unless such SSG Product, Cooperative Application
     and/or service is in Compliance with InterTrust Specifications. InterTrust
     may, from time to time in its sole discretion, modify InterTrust
     Specifications to accommodate changes in InterTrust Technology, and any
     related InterTrust product development, for purposes of, for example,
     improving architectural integrity, functional capability, standardization,
     security capability, efficiency, and/or interoperability of InterTrust
     Commerce-based technology, components, products and services (a "New
                                                                      ---
     Specification"). InterTrust shall use commercially reasonable efforts to
     -------------
     maintain compatibility 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 releases a New
     Specification that applies to any portion of a Cooperative Application, SSG
     Product and/or service then being performed or distributed by SSG (as
     applicable), SSG shall bring any further such products delivered to
     customers, and/or any services for any such products (as applicable), 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, SSG Product and/or service (the "Next Version"), as earlier
                                                   ------------
     applicable, but only to the extent that SSG receives notice of such New
     Specification within a reasonably sufficient time of such Next Version to
     accommodate new aspects of such New Specification; and (ii) [*] ([*])
     months after SSG receives a released copy of such New Specification.
     InterTrust and SSG further agree that SSG shall, within [*] ([*]) months
     after receiving a released copy of such New Specification, implement such
     new aspects of such New Specification for all applicable services
     supporting and/or employing SSG Products and Cooperative Applications
     and/or any other products employing InterTrust Technology provided to
     customers and not meeting such New Specification. Notwithstanding the
     foregoing, should serious technical interoperability and/or security
     requirements commercially necessitate more prompt action, SSG and
     InterTrust will confer and agree upon the most aggressive, practical
     schedule feasible to ensure Compliance with the New Specification for all
     SSG Products, Cooperative Applications, and any services relating to such
     products or applications. Under such conditions, SSG shall take whatever
     commercially

     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. SSG acknowledges that: (i) in support of
              ------------------
     InterTrust Technology, InterTrust may implement one or more certification
     programs designed to ensure that licensed products and/or associated
     services (including SSG Products and any Cooperative Applications) use
     InterTrust Technology and/or Modified Technology in Compliance with
     InterTrust Specifications in accordance with this Agreement (the
     "Certification Program(s)"); and (ii) such a Certification Program(s) is
      ------------------------
     important 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. Such Certification Programs may, in
     InterTrust's sole discretion, require, for example, SSG: (a) to use a suite
     of test software provided by InterTrust for use by SSG to test and verify
     that Cooperative Applications and SSG Products (and/or associated services)
     are in Compliance with InterTrust Specifications; (b) to submit samples of
     Cooperative Applications and SSG Products and associated programs,
     parameter data, and other information (in object code form unless source
     code is necessary or reasonably appropriate) that may be technically
     material to Compliance with InterTrust Specifications, prior to first
     commercial distribution, sale, other transfer to, or use by, a customer or
     SSG service, as applicable, so as to allow InterTrust (or an InterTrust
     delegate) to perform confidential testing ("Certification Testing"); and
                                                 ---------------------
     (c) to the extent that options (a) or (b) immediately above do not, or can
     not reasonably be anticipated to, provide sufficient information to verify
     Compliance, to provide InterTrust with full and detailed specifications and
     documentation related to SSG's use of InterTrust Technology and Modified
     Technology for SSG Products, Cooperative Applications, and any associated
     services, but only to the extent that any such specifications and
     documentation may be material to Certification Testing. SSG shall comply
     with any Certification Program established by InterTrust in accordance
     herewith, and all specifications and documentation provided shall be
     certified by an authorized representative of SSG. In connection with any
     such Certification Testing, particularly the testing of products and/or
     services, as applicable, InterTrust (or an InterTrust delegate) will
     respond in a reasonably prompt manner following receipt of submitted
     products and access to, or receipt of technology supporting, such service,
     unless commercially reasonable factors prolong such testing. Such response
     shall be in the form of: (1) a written approval that the product or service
     is certified (such SSG Products and Cooperative Applications not being
     Compliant until such certification has been granted); or (2) 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.

          (d) Costs. To defray costs associated with the performance and
              -----
     administration of the Certification Program, in connection with the
     certification of any product or service SSG shall be charged a reasonable
     fee not to exceed industry norms for similar testing activities (and, if
     conducted by InterTrust, the full cost incurred by InterTrust in performing
     and administering such tests). An estimate of such fee shall be provided to

     SSG, as applicable, as soon as reasonably practical upon SSG's submission
     of samples, or documentation for and access to services, for testing, and
     such fee shall be paid by SSG in accordance with standard industry
     practices, as available.

          (e) Translation of Material in Foreign Languages. InterTrust shall
              --------------------------------------------
     have the right to receive and approve (to the extent referencing InterTrust
     Technology or capabilities and/or functions enabled by InterTrust
     Technology) any non-English translations made by or for SSG of
     documentation provided by SSG concerning SSG Products, and Cooperative
     Applications, and any related services (including Distributable
     Documentation), legends and Notices required pursuant to Section 6.3 hereof
     and other required notices, and all versions of InterTrust Technology.

     6.2  Customer Agreements. SSG shall not distribute any Cooperative
          -------------------
Application or SSG Product to any Person unless SSG shall have first notified
and required such Person to execute a form of customer agreement (the "Customer
                                                                       --------
Agreement(s)") provided by SSG, such Customers Agreement forms having: (i)
------------
terms relating to InterTrust Technology and InterTrust's rights and interests
consistent with and reflective of the terms of this Agreement; and (ii) been
previously approved in writing by InterTrust (such approval not to be withheld
unless such Customer Agreement(s) does not reasonably protect InterTrust's
rights under this Agreement or sufficiently protect InterTrust's Intellectual
Property Rights. Once approved by InterTrust, the Customer Agreement(s) shall be
set forth as an Exhibit to this Agreement and may be used, as applicable, by SSG
as a form agreement unless and until: (a) SSG modifies such agreement (provided
that InterTrust has approved such modification in writing); or (b) InterTrust
reasonably requires that SSG alter the Customer Agreement to protect
InterTrust's rights under this Agreement or to protect its Intellectual Property
Rights, for example in view of court decisions and/or applicable regulations
under the circumstances. At a minimum, the Customer Agreement forms will: (i)
prohibit customers from disassembling, modifying or reverse engineering any
portion of the InterTrust Technology incorporated in the SSG Product or
Cooperative Application; (ii) stipulate that such customer has no right to use
the SSG Product or Cooperative Application to engage in or perform any
Clearinghouse Functions whatsoever unless such customer is an Authorized
Clearinghouse Provider or an authorized sublicensee under Section 5.2 hereof;
(iii) grant such customer only a limited license to use the Cooperative
Application or SSG Product, and, as applicable, to (A) incorporate Authorized
Application Software into such customer's software product to provide a Rights
User Node that is Compliant with InterTrust Specifications or (B) develop and
incorporate software components that provide the interface for and support
operation in conjunction with a Rights User Node provided by InterTrust Commerce
Technology; (iv) permit such customer to engage SSG and/or an Authorized
Clearinghouse Provider to perform Clearinghouse Functions with respect to such
software product; (v) provide that if such customer is permitted to modify any
portion of InterTrust Technology, such customer shall grant to InterTrust a
license on substantially the same terms as Section 8.4; (vi) provide that the
Customer Agreement is to and for InterTrust's benefit and may be enforced by
InterTrust at its discretion; and (vii) contain such other provisions as
stipulated herein. SSG agrees that to the extent any form of Customer Agreement
might be deemed to be unenforceable or otherwise ineffective in any
jurisdiction, SSG shall, upon notification by InterTrust, 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. SSG agrees and acknowledges that SSG'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. SSG shall not be obligated to file any claim in
litigation to enforce the terms of Customer Agreement(s); provided that SSG
                                                          -------- ----
shall, if requested by InterTrust, terminate such Customer Agreement(s) upon a
material breach by such customer(s).

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

          (a) Product Legends and Notices. SSG shall, in accordance with
              ---------------------------
     InterTrust's instructions and/or approved exemplars and samples provided
     from time to time by InterTrust to SSG, place Notices (as hereinafter
     defined) on all Cooperative Applications, SSG Products, documentation,
     marketing and advertising materials therefor, and for associated services,
     on all packaging for any physical media containing any such products, and
     on all initialization and/or start-up screens of any stand-alone software
     developed by or for SSG 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 SSG Products and Cooperative
     Applications are "InterTrustworthy" and are being delivered using
     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 (a) in the opinion of InterTrust's
     counsel, assist in protecting InterTrust intellectual property and other
     InterTrust rights under the laws of any relevant jurisdiction, (b) are
     commercially reasonable means to protect InterTrust rights without being
     overly intrusive or unreasonably costly to SSG's sales and marketing
     efforts, and (c) in InterTrust's reasonable opinion or upon written opinion
     of InterTrust's outside legal counsel, cannot be adequately addressed in
     the Customer Agreement. Before any Notices are omitted pursuant to
     subsections (b) and (c) immediately above, SSG shall advise InterTrust in
     writing of the circumstances and the Parties' Project Managers shall
     directly discuss the issue. SSG shall not, and shall not permit any Person
     to, remove, alter, cover, obfuscate or otherwise deface any InterTrust
     Trademarks or Notices on any InterTrust Technology or associated
     documentation, marketing and advertising materials therefor. Compliance
     with subsections (i) and (iv) above shall constitute conditions precedent
     to the licenses granted under Article 5 hereof.

          (b) Network Notices. SSG shall, in accordance with InterTrust's
              ---------------
     instructions or approved exemplars and samples provided from time to time
     by InterTrust to SSG: (i) place Notices specified by InterTrust, which
     Notices shall not unreasonably detract from, or interfere with, SSG content
     or branding, on all of SSG's start-up screens or initial user interface
     menus of any server host environment generated by or referencing the
     Cooperative Applications and/or the SSG Products or any associated
     services; and (ii) include a link from any home pages or any Web page of
     SSG, any other SOFTBANK Affiliate, and any SSG customer or licensee (who
     does not object to such link), that uses InterTrust Commerce Technology in
     its products or in connection with its services, which materially promotes
     or otherwise supports SSG Products, Cooperative Applications and associated
     services, to a home page that InterTrust may provide for such purpose on
     the World Wide Web or the equivalent thereof on any other electronic
     network.

     Notwithstanding the foregoing, neither SSG nor any SOFTBANK Affiliate shall
     have any obligation to provide any such link to the extent that
     InterTrust's home page: (a) references any software distributor other than
     SSG, SOFTBANK, or a SOFTBANK Affiliate as an InterTrust provider of
     software distribution clearinghouse transaction services; or (b) contains
     materials, or points to another website that contains materials, directly
     and substantially in conflict with SSG's material commercial interests.
     Before any such link is removed or not established for the reasons set
     forth in subsection (a) and (b) immediately above, SSG shall provide
     InterTrust with four (4) days prior written notice describing any such
     material conflict and afford InterTrust the opportunity to comment upon
     and, if appropriate, correct such conflict. InterTrust shall be afforded
     the opportunity to have a link re-established promptly upon any
     rectification of a material conflict.

          (c) Prospective Notice. The Notices shall be effective beginning on
              ------------------
     the date InterTrust gives SSG written notice thereof and SSG shall as soon
     as reasonably commercially practicable implement and/or comply with
     applicable portions thereof.

     6.4  InterTrust Trademarks.
          ---------------------

          (a) Standards. SSG expressly recognizes the importance of
              ---------
     InterTrust's reputation and goodwill, and of maintaining high, uniformly
     applied standards of quality in connection with SSG's use and distribution
     of products, applications, and services pursuant hereto bearing InterTrust
     Trademarks. Consequently, to maintain InterTrust's interest in and rights
     to the InterTrust Trademarks, products, and associated services, and to
     maintain in the mind of the public and customers that InterTrust Technology
     and its components represent sufficient levels of quality, trust and
     reliability, SSG shall utilize the InterTrust Trademarks in accordance with
     trademark guidelines (including approved samples and exemplars) as provided
     herein and as may be provided to SSG by InterTrust. Such trademark
     guidelines shall: (i) include a list of InterTrust trademarks that have
     been registered, or applied for, and shall specify restrictions on use, if
     any, including permitted and prohibited countries and jurisdictions; and
     (ii) may be revised from time to time by InterTrust. InterTrust Trademarks,
     as listed on Exhibit C attached hereto, may be reasonably modified by
     InterTrust from time to time upon InterTrust's provision to SSG of
     reasonable prior written notice. Any such modification shall not include
     any names, logos or marks that substantially conflict with any then-
     existing trademark rights of SSG.

          (b) Trademark Ownership; Contestability. SSG acknowledges and agrees
              -----------------------------------
     that all uses of InterTrust Trademarks as permitted hereunder, and the
     goodwill associated therewith, shall inure solely to the benefit of
     InterTrust. SSG 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. SSG agrees to make available to InterTrust,
     upon request, copies of SSG'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
     InterTrust Trademarks by SSG in each country.

          (c) Confusing Similarity. SSG shall not use any marks identical with
              --------------------
     or confusingly similar to any of the InterTrust Trademarks, shall not
     register or attempt to

     register any marks identical with or confusingly similar to InterTrust's
     Trademarks, and shall not permit any SOFTBANK Affiliate to use or affix any
     trademark of such Affiliate on any SSG Product supplied to such Affiliate,
     to the extent such Affiliate distributes, provides services for, or
     transfers to others any product other than a product incorporating
     InterTrust Technology, using Secure Containers that bears a trademark of
     such Affiliate.

          (d) Prospective Notice. Changes in the InterTrust Trademarks and such
              ------------------
     standards of quality shall be effective beginning on the date InterTrust
     gives SSG written notice thereof and SSG shall, as soon as reasonably
     commercially practicable thereafter, implement and/or comply with such
     respective portions thereof.

     6.5  SSG's Use of SSG Trademarks on Cooperative Applications and SSG
          ---------------------------------------------------------------
Products. To promote the branded and distinct identity of any InterTrust
--------
Compliant Cooperative Application, SSG Products, associated services or any
other such products used in commerce by SSG and/or distributed, sold or
otherwise transferred by SSG to Customers as provided hereunder, SSG
acknowledges and agrees that any trademark or logo used by SSG in commerce to
specifically identify, label or market a Cooperative Application, SSG Product,
or services associated therewith (other than trademark or logos that serve to
generally identify SSG or SOFTBANK, or any Affiliate or sublicensee thereof)
shall not, concurrently or thereafter, be used to identify any product or
services other than such SSG Products, Cooperative Applications and associated
services, whether by SSG or pursuant to license or sublicense from SSG.

     6.6  SSG Trademarks. Subject to the terms and conditions of this
          --------------
Agreement, SSG grants to InterTrust during the term of this Agreement a limited,
nonexclusive, royalty-free, worldwide license, without the right of sublicense
except to InterTrust's Affiliates, to use the SSG Trademarks solely in
connection with any publicity pursuant to Article 8 hereof, unless otherwise
agreed by SSG. InterTrust shall obtain permission from SSG for any further use
of SSG's Trademarks and shall comply with SSG instructions provided in writing
by SSG concerning such further use of any SSG Trademarks. InterTrust shall
comply with any reasonable guidelines provided in writing by SSG concerning such
use of any SSG Trademarks and shall comply with the provisions of Section 6.4 as
reasonably applied to the use of SSG Trademarks. Such SSG Trademark guidelines
shall include a list of SSG Trademarks that have been registered, applied for,
or used in interstate commerce and shall specify restrictions on use, including
permitted countries and jurisdictions. SSG Trademarks, as listed on Exhibit C
attached hereto, may be reasonably modified by SSG from time to time upon SSG's
provision to InterTrust of reasonable prior written notice thereof. Any such
modification will not include any names, logos or marks that substantially
conflict with then-existing trademark rights of InterTrust.

     7.3  Currency. Gross Commercial Value and all consideration received by
          --------
SSG pursuant to Sections 7.1(a)(ii) or 7.1(a)(iii) in a currency other than U.S.
dollars shall be converted by SSG to U.S. dollars on a monthly basis for
purposes of payment to InterTrust on a quarterly basis (unless otherwise
specified by InterTrust in its sole discretion to be paid in another single
alternative currency upon providing ninety (90) days prior written notice
thereof) according to the official rate of exchange for such currency, as
published by the Marine Midland Bank on the last business day during each
calendar month of a calendar quarter for which such royalties are due. If the
Marine Midland Bank ceases or fails to publish such official rate of 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 (San Francisco, California) or its legal successor on the last working
day of such calendar quarter for which such royalties are due.

     7.4  Taxes. SSG shall pay taxes, including but not limited to withholding

sales, use, value-added and other taxes, duties and other charges that may fall
due with respect to the transfer to or licensing, reproduction, distribution,

hereunder shall bear interest (compounded daily) at the rate of [*] percent
([*]%) 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 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 SSG 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 SSG's express obligation to timely provide any and all payments due to
InterTrust hereunder.

     7.6  Audit. SSG shall maintain at its principal place of business during
          -----
the term of this Agreement and for a period of five (5) years thereafter all

SSG will permit an auditor or agent of InterTrust's choice (subject to SSG's
consent, which shall not be unreasonably withheld or delayed) 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
SSG's reported royalty statements and payments provided by SSG or compliance
with the license terms and other material obligations hereunder. SSG shall pay
any unpaid delinquent amounts within ten (10) days of InterTrust's request. To
the extent such examination: (a) discloses an underpayment of more than [*]
dollars ($[*]) and such underpayment represents a sum greater than [*] percent
([*]%) of the sums paid to InterTrust by SSG during the applicable period
subject to such audit; or (b) discloses an underpayment of more than [*] dollars
($[*]), SSG 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. If an audit reveals an overpayment, InterTrust shall
notify SSG of such overpayment and SSG will apply the amount of such overpayment
against future royalties due and payable to InterTrust. Notwithstanding the
foregoing, within thirty (30) days of a request by SSG, InterTrust shall
reimburse SSG up to [*] dollars ($[*]) of any such overpayment amount; provided
that InterTrust posted a profit in accordance with GAAP in the calendar year
preceding such request. Any balance will be paid from future royalties as
provided for above.

application products and client software) shipped annually (based on annualized
volumes measured in the highest volume quarter for such units within the
previous five (5) calendar quarters preceding such agreement, or reasonably
projected for such units in the next four (4) calendar quarters if such
application product has not been shipped in each of the previous five (5)
quarters). The Additional Period shall cease immediately (i) upon a failure by
SSG to spend four million dollars ($4,000,000) in the aggregate in the technical
development and/or promotion and sale of SSG Products or Cooperative Application
Products directly related to supporting Clearinghouse Function services on or
before the first anniversary of SSG's receipt of InterTrust's SDK 1.0 (beta
version) (such amount to be calculated in accordance with generally accepted US
accounting principles consistently applied (GAAP) and excluding any fees or
royalties paid to InterTrust pursuant to this Agreement) or (ii) should SSG fail
to commercially release a SSG Product on or before twelve (12) months after
InterTrust has provided SSG with its SDK 1.0 (beta version). InterTrust may, at
any time, relieve itself of all of the obligations set forth in this Section
10.1 by, at its discretion, either: (a) paying to SSG an amount equal to twice
SSG's direct expenses (the "Direct Expenses") incurred, limited to the amount of
                            ---------------
money that SSG can demonstrate through financial records (kept in accordance
with GAAP) that it has directly expended in connection with the technical
development or promotion and sale of SSG Products or Cooperative Applications as
contemplated hereunder, provided that such payment amount shall not exceed ten
million dollars ($10,000,000) in the aggregate; or (ii) transferring to SSG (at
no cost) 174,947 shares of InterTrust's equity securities, such type of equity
securities being Class A Common Stock or a more senior security, and otherwise
the type of security being within InterTrust's sole reasonable commercial
discretion, and the method of transfer being such method as upon which the
Parties may agree in the exercise of their discretion.  Notwithstanding the
foregoing, in the event that InterTrust chooses to transfer such 174,947 shares
to SSG and the fair market value of such shares, as determined by InterTrust's
board of directors in the exercise of good faith, is less than the Direct
Expenses, InterTrust shall pay to SSG an amount equivalent in cash and/or the
value of additional shares equal to the difference between the amount of the
Direct Expenses and such fair market value of such shares.  To the extent
InterTrust complies with this Section 10.1, InterTrust shall not be restricted
from working with or licensing any technology or Intellectual Property to any
Person.

     10.2  SSG Partnering Commitment.  In partial consideration for:  (i)
           -------------------------
InterTrust's performance of its obligations hereunder, including providing to
SSG material access to confidential InterTrust Technology and Intellectual
Property; (ii) the rights granted to SSG hereunder; and (iii) InterTrust's
partnering commitment to SSG as set forth in Section 10.1 hereof, SSG agrees to
the following partnering commitment (the "SSG Partnering Commitment").  Without

obtaining the express prior written consent of a Designated Officer of
InterTrust (as defined in Section 11.2(b) hereof), which consent InterTrust may
grant or deny in its sole discretion, during the First Period, SSG shall: (a)
exclusively use the InterTrust Technology as its Secure Container and rights
management technology solution and refrain from performing any transactions or
engaging in the creation of any business relationships relating to Secure
Containers other than those employing the InterTrust Technology; and (b) not
participate in, assist, or promote the development, use or exploitation of any
technology or products (other than the InterTrust Technology) that contain or
include any material portion of the capabilities set forth in the "Special
                                                                   -------

---------------------
to the subject matter of subparagraph (b) immediately above, the First Period
shall automatically (and without any further action) be extended for a period
ending eighteen (18) months from the Effective Date.  Notwithstanding the
foregoing:  (1) any obligation pursuant to this Section 10.2 shall immediately
cease, at SSG's option (upon the agreement of both UCA and SIS), if InterTrust
has not provided the SDK 1.0 to SSG by the end of the second quarter (Q2) 1997;
and (2) after such First Period, SSG may participate in, assist, or promote the
development, use or exploitation of (A) any technology or products, so long as
such technology or products do not include, and are not specially adapted to
enable, any material portion of the Special Advanced Technologies and (B) any
technology or products that include, or are specially adapted to enable, any
material portion of the Special Advanced Technologies to the extent that such
Special Advanced Technologies may be incorporated by InterTrust in InterTrust
Technology or rightfully provided to SSG by another InterTrust licensee, and
whereby such right to use said Special Advanced Technologies is derived
exclusively from and used solely pursuant to this Agreement, or from such other
InterTrust licensee as expressly allowed in its license agreement with
InterTrust.  To the extent SSG complies with this Section 10.2, SSG shall not be
restricted from developing or pursuing any business models or activities
consistent with its licenses hereunder with any Person.

     10.3  Additional Provisions.  Any material breach of the foregoing
           ---------------------
provisions by a Party shall be subject to the specific remedies set forth in
Section 13.3, in addition to other remedies available to thee other party under
this Agreement, at law, or in equity.  If one Party has been relieved of its
Partner Commitment as set forth in this Article 10, the other Party shall be
relieved of its Partnering Commitment as well.  In all events (except pursuant
to Section 15.4 hereof), neither Party's Partnering Commitment to the other
shall extend beyond eighteen (18) months after the Effective Date.

                         ARTICLE 11. CONFIDENTIALITY.

     11.1  Classification of Technology and Documents For Confidentiality
           --------------------------------------------------------------
Purposes.  For ease in complying with the terms of this Article 11, information
--------
and documents to be exchanged by the Parties shall be marked, as appropriate, to
identify the confidential or nonconfidential nature of the information.  As
regards InterTrust Technology (including Documentation) and other documents or
information provided by InterTrust to SSG hereunder, such information shall be
marked or indicated as:  (i) "Unclassified"; (ii) "Confidential"; or (iii) "Top
Secret."  SSG information shall be marked as:  (a) "Unclassified" or (b)
"Confidential."  A Party and its authorized personnel shall exercise careful
judgment when they are in possession of information of the other Party that has
not been marked or indicated with one of the above-described classifications.
If any information provided by one Party has not been marked or indicated as
above and is not known with certainty by the receiving Party to have been either
publicly released or otherwise classified as "Unclassified," then such other
Party, its employees and any other person authorized to possess such information
shall treat such information as "Confidential" except information provided by
InterTrust relating to security capabilities, trustedness, and architecture (or
design) integrity of the InterTrust Technology, which shall be considered to be
"Top Secret" and shall be handled as provided by Section 11.2(b) hereof.

     11.2  InterTrust Information.
           ----------------------

           (a)  Confidential Information.  To the extent that SSG 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

     ("InterTrust Confidential Information"), SSG shall hold such InterTrust
     -------------------------------------
     Confidential Information in strict confidence and in a manner that:  (i) is
     sufficiently secure for the character and content of the InterTrust
     Confidential Information; and (ii) is not less secure than procedures used
     by SSG to protect its comparably important information and technology. SSG
     shall not, without InterTrust's prior written consent, use, disclose,
     provide or otherwise make available any InterTrust Confidential Information
     to any person, except to any employee, director, consultant, agent or
     professional consultant ("Agents") of SSG or one or more of SSG's permitted
                               ------
     sublicensees as authorized under the terms and conditions of this
     Agreement, and their Agents of which each shall operate under the same
     restrictions as SSG.  Furthermore, in each case of disclosure to an Agent
     of SSG or an authorized sublicensee, access to such InterTrust Confidential
     Information shall be allowed only to Agents who have a reasonable need to
     know such InterTrust Confidential Information, and then only to the extent
     necessary to enable SSG or any such authorized sublicensee to use
     InterTrust Confidential Information solely to exercise its license (or
     sublicense) hereunder and/or as expressly allowed hereunder.  SSG and any
     such sublicensees, as the case may be, shall:  (a) require their Agents
     having access to any portion of InterTrust Confidential Information to
     strictly maintain its confidentiality; and (b) ensure that each such Agent
     shall have executed with SSG and/or an authorized sublicensee (as
     applicable) a written non-disclosure/non-use agreement in the form set
     forth on Exhibit G at all hereto or as subsequently provided by InterTrust,
     or SSG's or such sublicensee's applicable form agreement which shall
     effectively and comparably bind such Agent to the same scope as
     InterTrust's form agreement, and which SSG's or sublicensee's form
     agreement shall be subject to InterTrust's reasonable prior written
     approval. SSG shall notify InterTrust

                                      -33-
<PAGE>

                                                                    CONFIDENTIAL

     promptly in writing of any unauthorized disclosure or other misuse or
     misappropriation of any portions of the InterTrust Confidential
     Information. SSG and any sublicensee (as appropriate) shall be fully
     responsible for any breach of SSG's or sublicensees' obligations under this
     Agreement by any Agent to whom such InterTrust Confidential Information has
     been disclosed. Any obligation of SSG to keep InterTrust Confidential
     Information in confidence shall expire thirty-six (36) months after
     disclosure of such information by InterTrust to SSG.

          (b)  Top Secret Information.  In order to protect InterTrust's rights,
               ----------------------
     the rights of InterTrust licensees, and the secure interoperability and
     reputation of InterTrust implementations, SSG 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 SSG'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.
     SSG shall allow disclosure of such Top Secret Information to no more than
     six (6) designated individual employees of SSG at any time (and to no
     sublicensee Agents), 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 SSG to use
     Top Secret Information solely to exercise its rights and perform its
     obligations under this Agreement. SSG shall not substitute any employee
     designated to receive Top Secret Information with another employee, unless
     such designated employee's employment with SSG has been terminated and such
     person is no longer able to serve the intended role. None of such employees
     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 G 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 SSG, which such receipt may
     be provided by fax communication if so requested in writing.
     Notwithstanding the foregoing, SSG and SSG 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 SSG signed by InterTrust's Chairman of the Board (the

     "Designated Officers"), nor shall SSG or such SSG employees disclose any
     --------------------
     Top Secret Information to any Person, except as described in this Section
     11.2(b).  If SSG becomes aware that any Top Secret Information has been
     disclosed or treated other than as set forth in this Section 11.2(b),
     and/or as specified in a Top Secrecy Agreement, SSG shall immediately
     inform InterTrust of such occurrence and take immediate steps to correct
     such compromise.  SSG shall maintain a log of the employees accessing and
     location of all originals and other tangible embodiments of all Top Secret
     Information.  SSG shall be fully responsible for any breach by any SSG
     employee of this Agreement related to the unauthorized use or disclosure of
     Top Secret Information.

     11.3  SSG Information.  To the extent that InterTrust receives SSG
           ---------------
confidential information that is either marked "confidential" when disclosed in
written form or indicated as "confidential" when disclosed orally ("SSG
                                                                    ---

InterTrust shall hold said SSG 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 SSG 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 SSG of the Modified Technology or such disclosures inherent in the
Certification Testing of SSG Products, Cooperative Applications and/or any
associated services pursuant hereto and only to the extent expressly specified
by InterTrust Specifications, SSG shall not disclose or otherwise provide or
make available any SSG Confidential Information 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 use, disclose, provide or otherwise make available any SSG
Confidential Information it has received in any form to any person except an
Agent of InterTrust. In a disclosure to Agents of InterTrust, access to SSG
Confidential Information shall be allowed only to Agents who have a reasonable
need to know such confidential information and only to the extent necessary to
enable InterTrust to use confidential information to exercise its rights and
perform its obligations hereunder. InterTrust shall: (a) require its Agents
having access to any portion of confidential information to strictly maintain
its confidentiality; and (b) ensure that each such Agent shall have executed
with InterTrust a written non-disclosure/non-use agreement provided by SSG, or
InterTrust's applicable form agreement which shall effectively and comparably
bind such Agent to the same scope as SSG's form agreement, and which InterTrust
form agreement shall be subject to SSG's reasonable prior written approval. Upon
such approval the SSG form agreement will be attached as an Exhibit hereto.
InterTrust agrees to notify SSG promptly in writing of any unauthorized
disclosure or other misuse or misappropriation of SSG 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 any Agent to whom such SSG Confidential Information has
been disclosed. Any obligation of InterTrust to keep SSG information in
confidence shall expire thirty-six (36) months after disclosure of such
information by SSG to InterTrust.

     11.4  Exceptions.  Notwithstanding the provisions of Sections 11.2 and 11.3
           ----------
above, and except as to "Top Secret" information as provided in Section 11.2(b),
the confidentiality restrictions herein shall not apply to 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 by 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 the discloser of such
information), as of the date such information is so received.  In the event any
Party is required by law, regulation or order of a court or other authority of
competent jurisdiction to disclose the other Party's Confidential Information,
such Party shall notify such other Party as promptly as possible, and shall,
upon such other Party's request, reasonably assist in challenging or restricting
the scope of such required disclosure.  Top Secret information may be disclosed
only upon InterTrust's prior written approval.  In all events, a Party subject
to such required disclosure shall disclose only such information that is
strictly required pursuant thereto and no further information.

     11.5  Confidentiality of Agreement and Publicity.  Except as otherwise
           ------------------------------------------
provided in Sections 9.1 and 11.4 hereof, neither Party hereto shall at any
time, without the prior written

conditions of this Agreement to any Person, other than: (i) Agents having a
substantial need to know; (ii) as required by law in connection with any initial
public offering of securities pursuant to a registration under the Securities

percent (1%) or more of the outstanding equity shares of such Party prior to an
IPO and having no reasonably anticipated conflict of interest with the

percent (1%) or more of the outstanding equity shares of such Party prior to an
IPO and having no reasonably anticipated conflict of interest with the
disclosing party; and/or (v) financial institutions, professional advisors
and/or other consultants having a reasonable need to know and having no
reasonably anticipated conflict of interest with the disclosing party. In each
and every case set forth above, the receiving Person shall be bound by a
confidentiality agreement sufficient in scope to protect the Parties' rights and
interests hereunder. Notwithstanding the foregoing provisions of this Section
11.5: (a) either Party may publicly discuss or otherwise disclose that an
agreement exists between the Parties to develop InterTrust Compliant electronic
commerce industry standards, products and services, 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 (b) either Party may

     use of any InterTrust Technology in any manner inconsistent with InterTrust
     Specifications or Documentation (collectively, the "Indemnification

     Exclusions").
     ----------

           (b)  SSG Indemnification.  Each of UCA and SIS shall jointly and
                -------------------
     severally 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) SSG's or any of its
     sublicensees' breach of any of its obligations, representations or
     warranties hereunder; (ii) InterTrust's proper use of SSG Trademarks as set
     forth herein; (iii) the design, manufacture, use, distribution and/or
     disposition by or for SSG of Modified Technology, Cooperative Applications
     or SSG Products, or performance of any service associated therewith, that
     would not have otherwise arisen out of SSG's use of the InterTrust
     Technology alone, except to the extent SSG is indemnified by InterTrust
     under Section 13.1(a) hereof; (iv) any Claim relating to the
     Indemnification Exclusions; and (v) any exercise by SSG or any of its
     sublicensees of the licenses hereunder that would not have otherwise arisen
     out of SSG's use of the InterTrust Technology alone, except to the extent
     SSG is indemnified by InterTrust under Section 13.1(a) hereof.

           (c)  Third Party Claims. In case any Claim is brought by a third
     party for which Claim indemnification is or may be provided hereunder the
     indemnified Party shall provide prompt written notice thereof to the other
     Party. Where obligated to indemnify such Claim, 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 reasonable attorneys' fees,
     incurred by such Party in defending itself. The Parties shall

                                                                    CONFIDENTIAL

     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 prior notice of
     any settlement of any Claim to be entered into by the other Party and to
     reasonable approval of a settlement to the extent such Party's rights
     would be directly and materially impaired. Without limiting the
     foregoing, in the event of any Claim or threatened Claim of [*] involving
     a portion of the [*]: (a) upon SSG's request and at SSG's expense,
     InterTrust will attempt to [*] the [*] or [*] SSG to continue to [*] and
     [*] in accordance with the terms hereof such portion of [*] on [*] to
     InterTrust (except that SSG may reasonably approve any terms relating to
     payment of any fees or royalties); or (b) at InterTrust's sole
     discretion, InterTrust may [*], [*] or [*] any [*] of the [*], as the
     case may be, so as to make [*] of the [*] while maintaining [*] of [*] or
     [*] of the [*] that are material to SSG's then-current or demonstrably
     anticipated use of such technology. If options (a) and (b) are not [*] as
     to such portion: (1) SSG may terminate the licenses granted hereunder in
     its sole discretion; and (2) to the extent InterTrust used reasonable
     commercial efforts to obtain a license or modify the technology as set
     forth in subsections (a) or (b), and InterTrust is reasonably exposed to
     liability from SSG's or its sublicensee's continued use of such portion
     of InterTrust Technology, InterTrust may in its discretion terminate the
     licenses granted hereunder with respect to such portion.

     13.2  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.

     13.3  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 5.3, 5.4, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 7.6,
10.1, 10.2, 15.3, 16.5 and 16.8 and Articles 8 and 11 hereof. Accordingly, each
Party agrees that if it or any of such Party's 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 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, each Party agrees that, in the event a Party
breaches any of its Partnering Commitments under Article 10 to the other Party,
the non-breaching Party shall be entitled, in addition to any other remedies
available at law or in equity, to extend the Partnering Commitment by the
amount of time left on such period (measured from the later of the date such
breach is admitted by breaching Party or established by a final judgment

                       ARTICLE 15. TERM AND TERMINATION.

     15.1 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 15.2. At the end of such twenty-five (25)
year term, this Agreement shall automatically renew for subsequent one (1) year
periods 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.

     15.2 Events of Termination. This Agreement, the licenses granted
          ---------------------
hereunder, and/or 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"):
                                                  --------------------

          (a)  If either Party, or, as relevant, any of its permitted
     sublicensees, materially defaults on any of its material obligations under
     this Agreement, the non-defaulting Party shall have the right, exercisable
     in its sole discretion, to initiate a termination procedure under this
     Agreement by written notice (sent in accordance with the provisions of
     Section 16.6 hereof) describing with reasonable specificity the nature of
     the default and requiring 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
     earnest due diligence

                                                                    CONFIDENTIAL

     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 SSG's breach of its payment
     obligations in accordance with Section 7.1 shall be five (5) business days.
     Notwithstanding any of the foregoing, a Party shall have the right both to
     immediately terminate this Agreement and to obtain injunctive relief in the
     event the other Party or any of its Agents or authorized sublicensees
     engages in any: (a) intentional, material unauthorized use of technology
     outside of the rights granted hereunder (or, in the case of SSG, any
     unauthorized disclosure of InterTrust Top Secret Information) and/or (b)
     willful, material unauthorized disclosure of Confidential Information.
     Further notwithstanding the foregoing, in the event the Closing fails to
     occur on or before August 19, 1996 pursuant to Section 2.1 hereof, SSG
     shall be in material breach of this Agreement and InterTrust may
     immediately, upon providing written notice to SSG and without opportunity
     to cure, terminate this Agreement.

          (b)  By a Party at its option, 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 the other Party 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 assignment or attempted assignment for the
     benefit of creditors for all or substantially all of its properties
     relevant to its business activities 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;

          (c)  Upon written notice to SSG, InterTrust may immediately terminate
     this Agreement in its sole discretion in the event SSG fails: (i) to
     distribute SSG Products and/or Cooperative Applications within sixty (60)
     months from the date InterTrust first delivers the SDK 1.0 to SSG, subject
     to any extension permitted under Section 6.1(a); (ii) to comply with the
     terms of Section 10.2 hereof; (iii) 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 SSG, whichever is earlier; or (iv) fails
     to timely make payments due under this Agreement on two or more occasions
     over a twelve (12) month period. Upon written notice to InterTrust, SSG may
     immediately terminate this Agreement in its sole discretion in the event
     InterTrust fails to comply with the terms of Section 10.1 hereof.

          (d)  A party to 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.

     15.3 Effect of Termination. Upon the expiration or termination hereof: (i)
          ---------------------
all licenses granted hereunder, all sublicenses granted by SSG pursuant to
Section 5.2, and all cooperative development efforts then being conducted
pursuant to all Cooperative Application Project Plans shall automatically
terminate; (ii) InterTrust shall have the right to retain all sums already paid
by SSG (and all SSG sublicensees) hereunder, and SSG (and all SSG sublicensees)
shall pay to

InterTrust all sums accrued but unpaid within thirty (30) days thereafter; and
(iii) SSG (and all SSG sublicensees) shall immediately discontinue use of
InterTrust Technology and/or the use of any portion of such InterTrust
Technology in any Modified Technology, and discontinue making, using, selling or
otherwise transferring or exploiting any product or service that in the absence
of a license hereunder would infringe any InterTrust Intellectual Property
Rights (including termination of distribution of Cooperative Applications and
SSG Products and any associated services); provided, however, that all licenses
                                           --------  -------  ----
granted to end-users pursuant to the then-existing Customer Agreements solely
for Applications Products shall continue in full force and effect in accordance
with the terms thereof (provided that such licenses do not provide any rights to
such end-users with respect to Clearinghouse Functions, other than as expressly
provided hereunder). 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, including all copies under its control of its sublicensees or their
Agents. 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 instruction to SSG: (a) by physical and secure pickup at SSG's offices
by an InterTrust officer designated in writing by such Designated Officer; or
(b) as otherwise may be determined by InterTrust in its discretion, as
commercially reasonable. Such delivery shall be during normal business hours and
in each instance to the hands of an InterTrust officer who receives a listing of
the contents of such delivery certified by an officer of SSG and audited and
countersigned by such InterTrust officer. 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.

     15.4 Survival. The respective rights and obligations of InterTrust and SSG
          --------
under the provisions of Sections 5.4, 6.5, 7.6 (but only for a period of five
years), 8.1, 8.2, 8.3, 8.4 (but only provision (i) thereof), 15.3, this Section
15.4, and Articles 11, 13 and 16 hereof shall survive expiration or termination
of this Agreement. Section 10.1 shall survive termination to the extent the
Agreement is properly terminated by SSG due to a material breach of the
Agreement by InterTrust pursuant to Section 15.2(a) hereof. Sections 9.3(c) and
10.2 shall survive termination to the extent the Agreement is properly
terminated by InterTrust due to a material breach of the Agreement by SSG
pursuant to Section 15.2(a) hereof. In the event that such a termination
pursuant to Section 15.2(a) occurs prior to delivery of SDK 1.0, such Partnering
Commitment as set forth in Sections 10.1 and 10.2, as applicable, shall run from
the Estimated date for delivery of such SDK as set forth on Exhibit B hereto as
of the Effective Date.

                          ARTICLE 16. MISCELLANEOUS.

     16.1 Governing Law. This Agreement, any and all actions arising out of or
          -------------
in any manner affecting the interpretation of this Agreement, and any actions
between the Parties involving the InterTrust Technology, any InterTrust Property
and/or any Confidential or Top Secret Information ("Party Disputes") shall be
                                                    --------------
governed solely by, and construed solely in accordance with, the laws of the
United States of America and the Commonwealth of Virginia, excluding that body
of law relating to conflict of laws. The Parties hereby acknowledge and agree
that the Convention on Contracts for the International Sale of Goods shall not
apply to this Agreement. To the extent permitted by law, the provisions of this
Agreement shall supersede any provisions of the Uniform Commercial Code as
adopted or made applicable to this Agreement in any competent jurisdiction.

     16.2 Venue and Jurisdiction. In connection with any litigation between the
          ----------------------
Parties involving a Party Dispute, each Party hereby unconditionally and
irrevocably consents to the exclusive jurisdiction and venue, as relevant, in
the Courts of the Commonwealth of Virginia and in the U.S. Federal District
Court, located in the City of Alexandria, Virginia (or any direct successor
thereto), and irrevocably: (i) waives any objection whatsoever (including any
objection with respect to venue) that any Party may now or hereafter have to the
jurisdiction or venue of said courts; and (ii) irrevocably consents to the
service of process of said courts in any matter relating to this Agreement by
the mailing of process by registered or certified mail, postage prepaid, at the
addresses specified in this Agreement. If necessary, SSG shall appoint a
registered agent in the State of Virginia for acceptance of service of process
and/or other notices provided for under this Agreement and shall notify
InterTrust of the identity of such registered agent within thirty (30) days
after the Effective Date.

     16.3 Compliance with Law and Export Controls. The Parties shall at all
          ---------------------------------------
times comply with all applicable U.S. and foreign federal, state, and local
laws, rules and regulations relating to the execution, delivery and performance
of this Agreement and to the InterTrust Technology Products and Modified
Technology. Additionally, SSG acknowledges that because one or more aspects of
the InterTrust Technology Products is likely to be subject to the export control
laws, regulations and requirements of the United States and other jurisdictions,
SSG Products and Cooperative Applications likely will require export and other
approvals as well. InterTrust shall use reasonable efforts at InterTrust's
expense, and SSG shall at InterTrust's request reasonably assist InterTrust at
SSG's expense, to obtain any license or other approval, if any, that may be
required for InterTrust to make the InterTrust Technology Products and/or
Documentation or information relating thereto available to and SSG or SOFTBANK
Affiliates. SSG shall, at SSG's expense, comply with all applicable laws
(including applicable U.S. export control laws and regulations) and obtain all
necessary governmental consents and approvals in connection with any sublicense
or with respect to the distribution of or export or re-export of the SSG
Products and Cooperative Applications (as well as other technology as expressly
permitted hereunder) that contain any part of the InterTrust Technology Products
or Modified Technology in accordance herewith. The Parties expressly agree that
any failure to obtain or any delay in obtaining such approval as to InterTrust
Technology or in connection with any SSG Product or Cooperative Application
shall not relieve SSG from its obligations under this Agreement. As relevant and
applicable, SSG and InterTrust shall: (a) promptly deliver to the other, as
available, documentation reasonably confirming that it has complied with its
responsibilities under this Section 16.3; and (b) obtain such consents and
approvals from appropriate governmental entities

as reasonably determined to be necessary for such further distribution,
exportation or re-exportation.

     16.4 Amendment or Modification. This Agreement may not be amended,
          -------------------------
modified or supplemented by the Parties in any manner, except by an instrument
in writing signed by the President or Chairman of InterTrust and a duly
authorized officer of SSG.

     16.5 No Assignment. Except as expressly provided in Section 5.2, SSG shall
          -------------
not assign or transfer its rights or obligations hereunder, without InterTrust's
prior written consent, which consent shall not be unreasonably withheld.
Notwithstanding the foregoing, SSG shall be entitled to assign or transfer such
rights or obligations hereunder to a SOFTBANK Affiliate in connection with any
merger or sale of substantially all of SSG's assets or business related to this
Agreement to such SOFTBANK Affiliate without such InterTrust consent; provided
                                                                      --------
that such SOFTBANK Affiliate does not own, control, or is not developing,
----
promoting, licensing or acquiring any Competitive Technology. InterTrust shall
not assign or transfer this Agreement or its rights or obligations hereunder to
any Person without SSG's prior written consent, which consent shall not be
unreasonably withheld. Notwithstanding the foregoing, InterTrust shall be
entitled to assign or transfer such rights or obligations hereunder in
connection with any merger or sale of substantially all of assets or business
related to this Agreement without such SSG consent. Subject to the foregoing,
this Agreement will benefit and bind the successors and permitted assigns of the
Parties. Any attempted transfer or assignment without such approval shall be
null and void ab initio and of no force or effect.

     16.8  No Third Party Beneficiaries. Nothing express or implied in this
           ----------------------------
Agreement is intended to confer, nor shall anything herein confer, upon any
Customer or any Person other than the Parties and any respective successors or

liabilities whatsoever. Notwithstanding the foregoing, to the extent permitted
by law, SSG grants InterTrust the right to enforce against any of SSG's
sublicenses the terms of the applicable sublicenses or agreements between SSG
and its sublicensees for the purpose of asserting SSG's rights in order to
protect and enforce InterTrust's rights to InterTrust Property and any other
InterTrust rights under this Agreement.

     16.9  No Agency. Nothing herein contained shall be construed to constitute
           ---------
the Parties hereto as partners or joint venturers or the agent of the other
Party in any sense of those terms whatsoever. Neither Party assumes any
liability of the other Party nor shall have any authority to enter into any
binding obligation on behalf of the other Party.

     16.10 Recovery of Costs and Expenses. If any Party to this Agreement
           ------------------------------
brings an action against the other Party to enforce its rights under this
Agreement, the prevailing Party shall be entitled to recover its costs and
expenses, including without limitation, reasonable attorneys' fees and costs
incurred in connection with such action, including any appeal of such action.

     16.11 Severability. If the application of any provision or provisions of
           ------------
this Agreement to any particular facts or circumstances shall be held to be
invalid or unenforceable by any court of competent jurisdiction, then: (i) the
validity and enforceability of such provision or provisions as applied to any
other particular facts or circumstances and the validity of other provisions of
this Agreement shall not in any way be affected or impaired thereby; and (ii)
such provision or provisions shall be reformed without further action by the
Parties hereto and only to the extent necessary to make such provision or
provisions valid and enforceable when applied to such particular facts and
circumstances.

     16.12 Counterparts; Facsimiles. This Agreement may be executed in any
           ------------------------
number of counterparts, each of which when so executed and delivered shall be
deemed an original, and such counterparts together shall constitute one and the
same instrument. Each Party shall receive a duplicate original of the
counterpart copy or copies executed by it. For purposes hereof, a facsimile copy

reason of labor dispute, strike, inability to obtain labor or materials, fire or
other action of the elements, accident, administrative or governmental
restriction or appropriation or other causes, 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. 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 force majeure shall use good faith efforts to comply as closely
as possible with the provisions of this Agreement and to avoid the effects of
such event to the extent possible.

     16.14 Entire Agreement. This Agreement represents the entire agreement of

<PAGE>

Preferred Stock to be received by such Purchaser and the Class A Voting Common
Stock issuable upon conversion thereof (collectively, the "Securities") will be
acquired for investment for such Purchaser's own account, not as a nominee or
agent, and not with a view to the resale or distribution of any part thereof,
and that such Purchaser has no present intention of selling, granting any
participation in, or otherwise distributing the same. By executing this
Agreement, such Purchaser further represents that such Purchaser does not have
any contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participation to such person or to any third person, with
respect to any of the Securities.

          3.3  Disclosure of Information.  Such Purchaser represents that it has

condition and results of operations of the Company.

able to fend for himself, can bear the economic risk of his investment, and has
such knowledge and experience in financial or business matters that he is
capable of evaluating the merits and risks of the investment in the Series B
Preferred Stock.  If other than an individual, Purchaser also represents either
(i) that it has not been organized for the purpose of acquiring the Series B
Preferred Stock or (ii) that if such Purchaser has been organized for the
purpose of acquiring the Series B Preferred Stock, that each of the equity
owners of such Purchaser is an investor of companies in the development stage

applicable regulations such Securities may be resold without registration under
the Act only in certain limited circumstances.  In this connection, such
Purchaser represents that it is familiar with SEC Rule 144, as presently in
effect, and understands the resale limitations imposed thereby and by the Act.

requested by the Company, with an opinion of counsel, reasonably satisfactory to
the Company that such disposition will not require registration of such shares

hereof, or to a shareholder of an investment corporation, or to the estate of
any such partner or retired partner or shareholder or the transfer by gift, will

Securities may bear one or all of the following legends:

                         B.   Prior to 270 days following the effective date of
the Initial Public Offering;

                         C.   During the period starting with the date of filing
of, and ending on the date 180 days immediately following the effective date of,

registration statement to be filed at the date filing would be required, in
which case the Company's obligation to use its reasonable efforts to register
under this Section 4.1(b) shall be deferred for a period not to exceed 120 days
from the date of receipt of the Request, provided that the Company may not
exercise this deferral right more than once during any twelve (12) month period.

               (ii)  Underwriting. If any registration pursuant to Section
                     ------------
4.1(b) shall be underwritten, the right of any Holder to registration pursuant
to Section 4.1(b) shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in such
underwriting as prescribed herein (unless otherwise mutually agreed by a
majority in interest of the Initiating Holders and each such Holder). The
Company shall (together with all Holders proposing to distribute their
securities through such underwriting) enter into an underwriting agreement in
customary form with the managing underwriter selected by the Company for such
underwriting (the "Managing Underwriter"). Notwithstanding any other provision
of this Section 4.1(b), if the Managing Underwriter advises

                                      -11-
<PAGE>

the Initiating Holders or the Company in writing that the number of Registrable
Securities proposed to be registered by such Initiating Holder or Holders
exceeds the maximum number of such shares which the Managing Underwriter
considers, in good faith, to be appropriate based upon market conditions and
other relevant factors (the "Maximum Number"), then (1) the 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.

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

                         ----------------------
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,

                                      -14-

<PAGE>

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.

                    (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.

                                      -15-
<PAGE>

                    (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

                                      -16-
<PAGE>

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

                           (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.  Notwithstanding the
immediately preceding sentence, a Purchaser may assign the rights to cause the
Company to register Registrable Securities pursuant to this Section 4.1 to an
investment fund or funds managed by it (a "Permitted Fund Transferee") which
acquires less than all of the Purchaser's shares if prior to such assignment and
transfer, the Purchaser submits to the Company an irrevocable, joint and several
undertaking for the benefit of the Company executed by the Purchaser and the
Permitted Fund Transferee(s) to exercise all of their rights to register
Registrable Securities pursuant to this Section 4.1 in tandem, in a manner
consistent with holding such rights as a group and exclusively represented on
all matters arising under this Agreement by a single Purchaser or Permitted Fund
Transferee appointed in such undertaking by the other parties thereto.

               (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

                                      -17-
<PAGE>

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).

               (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

                                      -18-
<PAGE>

have been converted) to a Permitted Fund Transferee or Transferees 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 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

                                      -19-
<PAGE>

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 if such assertion of appraisal rights would
prevent, restrict or otherwise inhibit such transaction from being accorded
pooling accounting treatment.

               (b)  Agreement 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 4.3.

               (c)  Termination of Agreement. The agreement of this Section 4.3
                    ------------------------
shall terminate at the earlier of (i) consummation of the Initial Public
Offering or (ii) ten (10) years from the Closing Date.

          4.4  Financial Information.
               ---------------------

               (a)  Annual and Quarterly Information.  The Company will mail the
                    --------------------------------
following reports to each Purchaser for so long as such Purchaser is a holder
(or such Purchaser and a Permitted Fund Transferee or Transferees are the
collective holders) of at least eighty (80%) percent of shares of Series B
Preferred Stock purchased by such person hereunder (or shares of Class A Voting
Common Stock issued upon conversion of shares of Series B Preferred Stock):

                    (i)  As soon as practicable after the end of each fiscal
year, and in any event within 120 days thereafter, audited consolidated balance
sheets of the Company and its subsidiaries, if any, as of the end of such fiscal
year, and consolidated statements of income, consolidated statements of changes
in financial position and consolidated statements of stockholders' equity of the
Company and its subsidiaries, if any, for such year, prepared in accordance with
generally accepted accounting principles ("GAAP") and setting forth in each case
in comparative form the figures for the previous fiscal year; and

                    (ii) As soon as practicable after the end of each fiscal
quarter in each fiscal year of the Company and in any event within 60 days
thereafter, an unaudited consolidated balance sheet of the Company and its
subsidiaries, if any, as of the end of each such quarter, and unaudited
consolidated statements of income, unaudited consolidated statements of cash
flow and unaudited consolidated statements of stockholders' equity of the
Company and its subsidiaries, if any, for such period and for the current fiscal
year to date, prepared in accordance with GAAP (subject to normal year-end audit
adjustments).

this Section 4.4 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.

               4.5  Confidentiality.  Each Purchaser shall maintain in strictest
                    ---------------
confidence all financial information furnished to it by the Company pursuant to
Section 4.4 or otherwise and shall not use any of such financial information for
any purpose other than monitoring its equity investment in the Company.  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 4.5.

              CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS
                          OF SERIES B PREFERRED STOCK

                                       OF

                      INTERTRUST TECHNOLOGIES CORPORATION


     Pursuant to the provisions of Section 151 of the General Corporation Law of
the State of Delaware.

     INTERTRUST TECHNOLOGIES CORPORATION, a Delaware corporation (the
"Corporation"), certifies that pursuant to the authority conferred in Article
IVB of its Amended and Restated Certificate of Incorporation, and in accordance
with the provisions of Section 151 of the General Corporation Law of the State
of Delaware, its Board of Directors has adopted the following resolution
creating a series of 1,399,575 shares of Preferred Stock designated as Series B
Preferred Stock:

     RESOLVED, that a series of the Corporation's Preferred Stock consisting of
1,399,575 shares of Preferred Stock, be and hereby is designated as "Series B
Preferred Stock," par value $.001 per share, and that the Series B Preferred
Stock shall have the designations, powers, preferences and relative,
participating, optional or other rights and such qualifications, limitations and
restrictions as set forth in the Certificate of Designations, Preferences and
Rights of Series B Preferred Stock.

     This Certificate states that the Board of Directors does hereby fix and
herein state and fix such designations, powers, preferences, rights,
qualifications, limitations and restrictions thereof as follows:

          1.  Designation and Amount.  The shares of such series shall be
              ----------------------
designated as "Series B Preferred Stock" and the number of shares constituting
such series shall be 1,399,575.

          2.  Dividends and Distributions.
              ---------------------------

              (a) Subject to the rights of Series A Preferred Stock of the
Corporation, par value $0.001 per share (the "Series A Preferred Stock") and any
other series of Preferred Stock of the Corporation, par value $0.001 per share
(the "Preferred Stock") that may from time to time come into existence, the
holders of outstanding Series B Preferred Stock shall be entitled to receive the
same per share dividend as declared or paid on shares of Common Stock of the
Corporation, par value $0.001 per share (the "Common Stock") (other than
dividends on shares of Common Stock payable solely in shares of the Common
Stock).  Such dividends will be in an amount determined by the Board of
Directors of this Corporation (the "Board of Directors") and shall be payable,
when, as and if declared by the Board of Directors out of funds legally
available therefor.  Subject to the rights of Series A Preferred Stock and the
rights of other series of Preferred Stock that may from time to time come into
existence, dividends or distributions (other than dividends payable solely in
shares of Common Stock) may
<PAGE>

be declared and paid upon Common Stock in any fiscal year of this Corporation
only if dividends shall have been paid on or declared and set apart upon all
shares of Series B Preferred Stock on the same per share basis. The right to
such dividends on shares of Series B Preferred Stock shall not be cumulative and
no right shall accrue to holders of Series B Preferred Stock by reason of the
fact that dividends on such shares are not declared in any prior year, nor shall
any undeclared or unpaid dividend bear or accrue interest.

              (b) In the event this Corporation shall declare a distribution to
the holders of Common Stock (other than distributions payable solely in shares
of Common Stock) payable in cash, securities of other persons, evidences of
indebtedness issued by this Corporation or other persons, assets or options or
rights to purchase any such securities or evidences of indebtedness, then, in
each such case the holders of the Series B Preferred Stock shall be entitled to
a proportionate share of any such distribution as though the holders of the
Series B Preferred Stock were the holders of the number of shares of Class A
Voting Common Stock of the Corporation, par value $0.001 per share (the "Class A
Voting Common Stock") into which their respective shares of Series B Preferred
Stock are convertible as of the record date fixed for the determination of the
holders of Common Stock of this Corporation entitled to receive such
distribution.

          3.  Liquidation Preference.
              ----------------------

              (a) For purposes hereof, the original purchase price (the
"Original Series B Purchase Price") of the Series B Preferred Stock is $8.57 per
share of Series B Preferred Stock.

              (b) In the event of the liquidation, dissolution or winding up of
the Corporation, either voluntary or involuntary, subject to the rights of
series of Preferred Stock that may from time to time come into existence, the
holders of the Series A Preferred Stock will be entitled to receive out of the
assets of this Corporation, as a first preference prior and in preference to any
distribution of any of the assets or surplus funds of this Corporation to the
holders of Series B Preferred Stock and Common Stock by reason of their
ownership thereof, an amount per share equal to $5.11 per share (the "Original
Series A Purchase Price"), as appropriately adjusted for stock splits and
combinations, plus all declared and unpaid dividends with respect thereto. If
upon the occurrence of such event the assets and funds thus distributed among
the holders of the Series A Preferred Stock are insufficient to permit the
payment to such holders of the full amount of the first preference, then,
subject to the rights of series of Preferred Stock that may from time to time
come into existence, the entire assets and funds of the Corporation legally
available for distribution will be distributed ratably among the holders of the
Series A Preferred Stock (so that each holder receives for each share of Series
A Preferred Stock the same percentage of the applicable amount of the first
preference). Upon completion of the first preference distributions and any other
distribution that may be required with respect to any series of Preferred Stock
that may from time to time come into existence, the remaining assets of the
Corporation available for distribution to shareholders shall be distributed as a
second preference among the holders of Series A Preferred Stock, Series B
Preferred Stock and Common Stock pro rata based on (i) the number of shares of
Class A Voting Common Stock into which the then outstanding shares of Series A
Preferred Stock may be converted (assuming conversion into Class A Voting Common
Stock of all such Series A Preferred Stock at the then effective conversion
price as specified in the Corporation's Certificate of Incorporation) (the
"Series A Conversion Shares"), (ii) three times the number of shares of Class A
Voting Common Stock into which the then outstanding shares of Series B Preferred
Stock may be converted (assuming

                                      -2-
<PAGE>

conversion into Class A Voting Common Stock of all of such Series B Preferred
Stock at the then effective Conversion Price, as defined in Section 5(a)) (the
"Series B Conversion Shares") and (iii) the number of the then outstanding
shares of Common Stock until the holders of the Series B Preferred Stock shall
have received an aggregate of the Original Series B Purchase Price; provided,
                                                                    --------
that upon the holders of Series A Preferred Stock receipt of an aggregate of
$15.33 per share (including any other amounts paid pursuant to this Section
3(b)), the holders of the Series A Preferred Stock shall not be entitled to any
further distribution of the remaining assets of the Corporation available for
distribution to shareholders and such remaining assets shall be distributed
among the holders of Series B Preferred Stock and Common Stock pro rata based on
(m) three times the number of Series B Conversion Shares and (n) the sum of the
number of the then outstanding shares of Common Stock and the number of Series A
Conversion Shares until the holders of the Series B Preferred Stock shall have
received an aggregate amount per share equal to the Original Series B Purchase
Price, as appropriately adjusted for stock splits and combinations. Upon
completion of such second preference distributions and any other distribution
that may be required with respect to any series of Preferred Stock that may from
time to time come into existence, the remaining assets of the Corporation
available for distribution to shareholders shall be distributed as a third
preference among the holders of Series A Preferred Stock and Common Stock pro
rata based on (q) the number of Series A Conversion Shares and (r) the number of
shares of Common Stock then outstanding until the holders of Common Stock shall
have received an aggregate amount per share equal to the Original Series B
Purchase Price (including any other amounts paid pursuant to this Section 3(b)),
as appropriately adjusted for stock splits and dividends; provided, that upon
                                                          --------
the holders of Series A Preferred Stock receipt of an aggregate of $15.33 per
share (including any other amounts paid pursuant to this Section 3(b)), the
holders of Series A Preferred Stock shall not be entitled to any further
distribution of the remaining assets of the Corporation available for
distribution to shareholders. Thereafter, subject to the rights of series of
Preferred Stock that may from time to time come into existence, if any assets or
funds remain in this Corporation, all such remaining assets or funds shall be
distributed as a fourth preference among the holders of Series A Preferred
Stock, Series B Preferred Stock and Common Stock pro rata based on (v) the
number of Series A Conversion Shares, (w) the number of Series B Conversion
Shares and (x) the number of the then outstanding shares of Common Stock;
provided, that upon the holders of Series A Preferred Stock receipt of an
--------
aggregate of $15.33 per share (including any other amounts paid pursuant to
Section 3(b)), the holders of Series A Preferred Stock shall not be entitled to
any further distribution of the remaining assets of the Corporation available
for distribution to shareholders and such remaining assets shall be distributed
among the holders of Series B Preferred Stock and Common Stock pro rata based on
(y) the number of Series B Conversion Shares and (z) the number of shares of
Common Stock then outstanding.

              (c) For purposes of this Section 3 neither (i) an acquisition of
this Corporation by means of merger, consolidation or other form of corporate
reorganization nor (ii) a sale, lease or other transfer of all or substantially
all of the assets of this Corporation, shall

                                      -3-
<PAGE>

be treated as a liquidation, dissolution or winding up of this Corporation
within the meaning of this Section 3 unless such sale, lease or other transfer
shall be in connection with a plan of liquidation, dissolution or winding up of
the Corporation.

              (d) Any securities to be delivered to the holders of the Preferred
Stock and/or Common Stock pursuant to this Section 3 shall be valued as follows:

                  (i) Securities not subject to investment letter or other
similar restrictions on free marketability:

                      (A) If traded on a securities exchange or The Nasdaq
National Market or its successor or equivalent, the value shall be deemed to be
the average of the closing prices of the securities on such exchange over the
30-day period ending three (3) days prior to the closing;

                      (B) If actively traded over-the-counter, the value shall
be deemed to be the average of the closing bid prices over the 30-day period
ending three (3) days prior to the closing; and

                      (C) If there is no active public market, the value shall
be the fair market value thereof, as determined in good faith by the Board of
Directors.

                  (ii) The method of valuation of securities subject to
investment letter or other restrictions on free marketability shall be to make
an appropriate discount from the market value determined as above in (i) (A),
(B) or (C) to reflect the approximately fair market value thereof, as determined
in good faith by the Board of Directors.

          4.  Voting Rights.  Except as otherwise expressly provided in Section
              -------------
6 or as required by law, the holder of each share of Series B Preferred Stock
shall be entitled to the number of votes equal to the number of shares of Class
A Voting Common Stock into which such share of Series B Preferred Stock could
then be converted, and with respect to such share, shall have full voting rights
and powers equal to the voting rights and powers of the holders of Common Stock
(except as otherwise expressly provided herein or as required by law), voting
together with the Common Stock as a single class, and shall be entitled to
notice of any stockholders' meeting in accordance with the Bylaws of this
Corporation.  Fractional votes shall not, however, be permitted and any
fractional voting rights resulting from the above formula (after aggregating all
shares into which shares of Series B Preferred Stock held by each holder could
be converted) shall be rounded to the nearest whole number (with one-half being
rounded upward).

                                      -4-
<PAGE>

          5.  Conversion Rights.
              -----------------

              (a)  Right to Convert.
                   ----------------

                   (i) Optional Conversion. Each share of Series B Preferred
                       -------------------
Stock will be convertible, at the option of the holder thereof, at the office of
this Corporation or any transfer agent for the Preferred Stock, into Class A
Voting Common Stock. The number of shares of Class A Voting Common Stock into
which each share of Series B Preferred Stock will be converted will be equal to
the Original Series B Purchase Price of such Series B Preferred Stock divided by
the Conversion Price (as hereafter defined) for such Series B Preferred Stock,
such conversion ratio being referred to as the "Conversion Rate" for such Series
B Preferred Stock. The initial Conversion Price for the Series B Preferred Stock
will be the Original Purchase Price of such Series B Preferred Stock. The
initial Conversion Price for the Series B Preferred Stock will be subject to
adjustment as provided herein and the term "Conversion Price" shall mean, as of
any date, the initial Conversion Price as the same has been adjusted from time
to time pursuant to the provisions of Sections 5(c) and 5(d).

                   (ii) Automatic Conversion of Preferred Stock. Each share of
                        ---------------------------------------
Series B Preferred Stock will be converted automatically into shares of Class A
Voting Common Stock at the then effective Conversion Rate for such Series B
Preferred Stock (i) upon the written approval of a majority of the holders of
the shares of Series B Preferred Stock then outstanding, voting together as a
series or (ii) immediately prior to the closing of a public offering pursuant to
a registration statement (other than a registration statement relating either to
the sale of securities to employees of the Corporation pursuant to a stock
option, stock purchase or similar plan or a transaction pursuant to Rule 145
under the Securities Act of 1933, as amended (the "Act")) under the Act covering
the Common Stock with a price per share in excess of $7.50 and aggregate
proceeds to the Corporation, net of underwriting discounts and commissions, in
excess of $10,000,000 (the "Initial Public Offering").

                   (iii) Fractional Shares Upon Conversion. No fractional shares
                         ---------------------------------
of Class A Voting Common Stock will be issued upon conversion of the Series B
Preferred Stock and any fractional share which otherwise would result from
conversion by a holder of all of his or her shares of Series B Preferred Stock
(with all the shares of a series taken together as a group) will be redeemed by
payment in an amount equal to the fair market value thereof as determined by the
Board of Directors for such series as promptly as funds are legally available
therefor. If more than one share of Series B Preferred Stock is surrendered for
conversion at any one time by the same holder, the number of full shares of
Class A Voting Common Stock to be issued upon conversion shall be computed on
the basis of the aggregate number of shares of Series B Preferred Stock so
surrendered.

              (b) Mechanics of Conversion. Before any holder of Series B
                  -----------------------
Preferred Stock will be entitled to convert the same into shares of Class A
Voting Common Stock, such holder will surrender the certificate or certificates
therefor, duly endorsed, at the office of this Corporation or of any transfer
agent for the Preferred Stock, and he will give written notice to the
Corporation stating the name or names in which the certificate or certificates
for shares of Class A Voting Common Stock are to be issued. This Corporation, as
soon as reasonably practicable

                                      -5-
<PAGE>

thereafter, will issue and deliver at such office to such holder or to the
nominee or nominees of such holder, a certificate or certificates for the number
of shares of Class A Voting Common Stock to which such holder will be entitled
as aforesaid. Such conversion will be deemed to have been made immediately prior
to the close of business on the date of notice of conversion provided by the
holder to this Corporation, and the person or persons entitled to receive the
shares of Class A Voting Common Stock issuable upon conversion will be treated
for all purposes as the record holder or holders of such shares of Class A
Voting Common Stock on such date. If the conversion is in connection with the
Initial Public Offering, the conversion will be conditioned upon the closing
with the underwriter of the sale of securities pursuant to such offering, in
which event the persons entitled to receive the Class A Voting Common Stock
issuable upon such conversion of the Series B Preferred Stock shall not be
deemed to have converted such Series B Preferred Stock until immediately prior
to the closing of such sale of securities.

              (c) Adjustment for Subdivisions or Combinations of Common Stock.
                  -----------------------------------------------------------
In the event this Corporation at any time or from time to time after the
effective date of the initial sale of Series B Preferred Stock (in each case,
the "Original Issue Date" for such series) effects a subdivision or combination
of its outstanding Common Stock into a greater or lesser number of shares
without a proportionate and corresponding subdivision or combination of its
outstanding shares of Series B Preferred Stock, then the existing Conversion
Price for such Series B Preferred Stock will be decreased or increased
proportionately.

              (d) Adjustment for Dividends, Distributions and Common Stock
                  --------------------------------------------------------
Equivalents.  In the event this Corporation at any time or from time to time
-----------
after the Original Issue Date for the Series B Preferred Stock, as applicable,
makes or issues, or fixes a record date for the determination of holders of
Common Stock (but not holders of such Series B Preferred Stock) entitled to
receive a dividend or other distribution payable in additional shares of Common
Stock or other securities or rights (hereinafter referred to as "Common Stock
Equivalents") convertible into or entitling the holder thereof to receive
additional shares of Common Stock without payment of any consideration by such
holder for such Common Stock Equivalents or the additional shares of Common
Stock, for the purpose of protecting the holders of Series B Preferred Stock
from any dilution in connection therewith, then and in each such event the
maximum number of shares (as set forth in the instrument relating thereto
without regard to any provisions contained therein for a subsequent adjustment
of such number) of Common Stock issuable in payment of such dividend or
distribution or upon conversion or exercise of such Common Stock Equivalents
will be deemed to be issued and outstanding as of the time of such issuance or,
in the event such a record date has been fixed, as of the close of business on
such record date.  In each such event the then existing Conversion Rate for
Series B Preferred Stock will be increased as of the time of such issuance or,
in the event such a record date has been fixed, as of the close of business on
such record date, by multiplying the Conversion Rate for such Series B Preferred
Stock by a fraction,

                                      -6-
<PAGE>

                  (1) the numerator of which will be the total number of shares
of Common Stock issued and outstanding immediately prior to the time of such
issuance or the close of business on such record date plus the number of shares
of Common Stock issuable in payment of such dividend or distribution or upon
conversion or exercise of such Common Stock Equivalents; and

                  (2) the denominator of which will be the total number of
shares of Common Stock issued and outstanding immediately prior to the time of
such issuance or the close of business on such record date; provided, however,
(i) if such record date has been fixed and such dividend is not fully paid or if
such distribution is not fully made on the date fixed therefor, the Conversion
Rate for the Series B Preferred Stock will be recomputed accordingly as of the
close of business on such record date and thereafter the Conversion Rate for the
Series B Preferred Stock will be adjusted pursuant to this Section as of the
time of actual payment of such dividends or distribution; (ii) if such Common
Stock Equivalents provide, with the passage of time or otherwise, for any
decrease in the number of shares of Common Stock issuable upon conversion or
exercise thereof, the Conversion Rate for the Series B Preferred Stock shall,
upon any such decrease becoming effective, be recomputed to reflect such
decrease insofar as it affects the rights of conversion or exercise of the
Common Stock Equivalents then outstanding, and (iii) upon the expiration of any
conversion rights or exercise under any unexercised Common Stock Equivalents,
the Conversion Rate for the Series B Preferred Stock computed upon the original
issue thereof shall, upon such expiration, be recomputed as if the only
additional shares of Common Stock issued were the shares of such stock, if any,
actually issued upon the conversion or exercise of such Common Stock
Equivalents.

              (e) No Impairment.  This Corporation, whether by amendment of its
                  -------------
Certificate of Incorporation or through any reorganization, transfer of assets,
merger, dissolution, issue or sale of securities or any other voluntary action,
will not avoid or seek to avoid the observance or performance of any of the
terms to be observed or performed hereunder by this Corporation, but at all
times in good faith will assist in the carrying out of all of such action as may
be necessary or appropriate in order to protect the conversion rights pursuant
to this Section 5(e) of the holders of the Series B Preferred Stock against
impairment.

              (f) Certificate as to Adjustments.  Upon the occurrence of each
                  -----------------------------
adjustment or readjustment of the Conversion Rate for the Series B Preferred
Stock pursuant to this Section 5, the Corporation at its expense promptly will
compute such adjustment or readjustment in accordance with the terms hereof and
prepare and furnish to each holder of such Series B Preferred Stock a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based.  This
Corporation, upon the written request at any time of any holder of Series B
Preferred Stock, will furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Rate for the Series B Preferred Stock at the time in effect, and
(iii) the number of shares of Class A Voting Common Stock and the amount, if
any, of other property which at the time would be received upon the conversion
of the Series B Preferred Stock held by such holder.

                                      -7-
<PAGE>

              (g) Notices of Record Date.  In the event of any taking by this
                  ----------------------
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any Common Stock
Equivalents or any right to subscribe for, purchase or otherwise acquire any
shares of stock of any class or any other securities or property, or to receive
any other right, the Corporation will mail to each holder of Series B Preferred
Stock at least ten (10) days prior to the date specified therein, a notice
specifying the date on which any such record is to be taken for the purpose of
such dividend, distribution or rights, and the amount and character of such
dividend, distribution or right.

              (h) Reservation of Stock Issuable Upon Conversion. This
                  ---------------------------------------------
Corporation at all times will reserve and keep available out of its authorized
but unissued shares of Class A Voting Common Stock solely for the purpose of
effecting the conversion of the shares of Series B Preferred Stock such number
of its shares of Class A Voting Common Stock as from time to time will be
sufficient to effect the conversion of all then outstanding shares of Series B
Preferred Stock; and if at any time the number of authorized but unissued shares
of Class A Voting Common Stock is not sufficient to effect the conversion of all
then outstanding shares of Series B Preferred Stock, in addition to such other
remedies as may be available to the holders of Series B Preferred Stock for such
failure, the Corporation will take such corporate action as, in the opinion of
its counsel, may be necessary to increase its authorized but unissued shares of
Class A Voting Common Stock to such number of shares as will be sufficient for
such purpose.

              (i) Notices. Any notices required by the provisions of this
                  -------
Section 5 to be given to the holders of shares of Series B Preferred Stock shall
be given in writing and shall be conclusively deemed effectively given to
persons located in the United States five days after deposit in the United
States mail, by registered or certified mail postage prepaid, or upon actual
receipt if given by any other method or to persons located outside of the United
States, addressed to such holder at his address appearing on the books of the
Corporation. To persons located outside of the United States, such notice will
be sent by telex or facsimile in cases where the corporation has notice of a
telex or facsimile number for such person.

              (j) Recapitalizations.  If at any time or from time to time there
                  -----------------
shall be a recapitalization of the Common Stock (other than a subdivision or
combination provided for in Section 5(d)), provision shall be made so that the
holders of the Series B Preferred Stock shall thereafter be entitled to receive
upon conversion of such shares of such Series B Preferred Stock the number of
shares of stock or other securities or property of the Corporation or otherwise,
to which a holder of Common Stock deliverable upon conversion of such Series B
Preferred Stock would have been entitled on such recapitalization.


          6.  Protective Provisions.  So long as any shares of Series B
              ---------------------
Preferred Stock are outstanding, this Corporation shall not without first
obtaining the approval (by vote or written consent, as provided by law) of the
holders of a majority of the then outstanding shares of Series B Preferred
Stock;

                                      -8-
<PAGE>

              (a) take any action that reclassifies any outstanding shares of
this Corporation's capital stock into shares of capital stock having preferences
or priority as to assets senior to the preferences and priority of the Series B
Preferred Stock;

              (b) authorize or issue, or obligate itself to issue, any equity
security other than the Series A Preferred Stock, including any other security
convertible into or exercisable for any equity security, having a preference or
priority as to assets senior to the preferences and priorities of the Series B
Preferred Stock;

              (c) amend or repeal Section 4 in any manner adversely affecting
the voting rights granted to the Series B Preferred Stock; or

              (d)  amend this Section 6.

     IN WITNESS WHEREOF, INTERTRUST TECHNOLOGIES CORPORATION has caused this
Certificate of Designations, Preferences and Rights of Series B Preferred Stock
to be executed by its Chairman and Chief Executive Officer and attested by its
Secretary, this 1st day of August, 1996.

     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

if such disclosure is not repeated in the other section.

     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 not waive did not exercise its right of first
             offer within the time period prescribed by the Series A Preferred
             Stock Agreement.

     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. As
             of July 17, 1996, the Company has not received any response to its
             March 12, 1996 letter to E-Data Corp.

          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

<PAGE>

             Company has initiated a dialogue with counsel to DI and believes
             that the demand and claims in the June 26, 1996 letter are
             unjustified.

             incorporating the Company's technology or covered by certain of the
             Company's patents. To date the Company has received non-refundable

             resolution allowing the officers of the Company to offer warrants
             to certain service providers in consideration of services rendered
             by such service providers. The Company is currently negotiating
             with certain of its service providers to issue such service
             providers warrants for the purchase of Class A Voting Common Stock
             and/or Class B Non-Voting Common Stock in lieu of services
             rendered, and anticipates that it will be necessary to issue
             warrants for the purchase of no more than an aggregate of 25,000 of
             such shares to such service providers.

          5. The Company has entered into an agreement with Robertson, Stephens
             & Co. for the purposes of raising capital and pursuing strategic
             relationships. The fees structure for this agreement ranges from 4%

                FORM OF LEGAL OPINION OF COUNSEL TO THE COMPANY
                -----------------------------------------------
<PAGE>

                                        August , 1996

SOFTBANK Holdings Inc.
10 Langley Road
Suite 403
Newton Center, Massachusetts 02159

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 583,431 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 August 1, 1996 (the "Purchase Agreement") between
the Company and SOFTBANK Holdings Inc., a Delaware corporation (the
"Purchaser").  This opinion is being delivered pursuant to Section 6.7 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 a basis for the opinions set forth
below.  In our examination we have assumed the genuineness of all signatures,
the legal 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 its 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 force and elect, 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 not 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
<PAGE>

SOFTBANK Holdings Inc.

Page 3

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 to 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 in 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 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
<PAGE>

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 set 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
<PAGE>

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 opinion, 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

          NEITHER THIS WARRANT NOR ANY OF THE SECURITIES ISSUABLE HEREUNDER HAVE
          BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "ACT"), AND AS SUCH MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED,

          OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH
          OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
          WITH THE ACT OR UNLESS SOLD IN FULL COMPLIANCE WITH RULE 144

                      INTERTRUST TECHNOLOGIES CORPORATION
                         Class B Common Stock Warrant



                               August ____, 1996

          THIS CERTIFIES THAT for value received, and subject to the provisions
and upon the terms and conditions hereinafter set forth, Upgrade Corporation of
America (the "Holder") is entitled to subscribe for and purchase shares (the
"Shares") of Class B Common Stock of InterTrust Technologies Corporation, a
Delaware corporation (the "Company"), at a price per share of $50.00, which
price may be reduced to $12.86 per share pursuant to the terms below (such price
and such other price as shall result, from time to time, from adjustments
specified below is referred to herein as the "Warrant Price"). The term "Grant
Date" shall mean the date set forth above.

          1.   Voluntary Exercise.  This Warrant may be exercised in full or in
               ------------------
part at any time or from time to time after the seven-year anniversary of the
Grant Date (the "Exercise Date") at a per share price of $50.00; provided,
however, that this Warrant may be exercised prior to the Exercise Date upon the
earlier to occur of the following events: (i) the Holder (alone or in
combination with other affiliates of Softbank Holding Ltd.) expends an aggregate
of $3,000,000 to develop, promote and market compliant electronic clearinghouse
technology and services using the Company's technology pursuant to the
Technology Development and License Agreement dated as of the date hereof (the
"Technology License") whereby such development, promotion or marketing activity
is specifically directed toward clearinghouse transactions involving the
original equipment manufacturer ("OEM") and independent software vendor ("ISV")
markets, and such aggregate amount is expended by the Holder within twenty-four
(24) months of the date the Company provides its SDK 1.0 product to the Holder
under the Technology License; or (ii) the Holder executes agreements with ten
(10) of its largest thirty (30) ISV and/or OEM customers (measured, consistent
with the Holder's practices, according to the
<PAGE>

                                                                    CONFIDENTIAL

Holder's revenue generated by such customers) to incorporate capabilities that
enable DigiBox creation and use within software programs produced by such
customers (and wherein such agreements can be publicly announced by the Holder
and the Company) (each of (i) and (ii) of this Paragraph 1 being referred to
herein as an "Early Exercise Event"). Upon the occurrence of an Early Exercise
Event, this Warrant shall be exercisable (a) at a price per share of $12.86
(subject to adjustment provided herein), and (b) for a period of 24 months after
the later of (x) the Early Exercise Event or (y) the consummation by the Company
of an IPO (as hereinafter defined) after which time this Warrant shall
terminate and be of no further force and effect. Notwithstanding the foregoing,
Holder's right to exercise this Warrant at the Warrant Price of $12.86 is
subject to Holder's continued commitment to the exploitation of the InterTrust
Technology, by Holder: (i) performing clearing services primarily for
transactions related to and/or derived from use of SSG Products (as defined in
the Technology License) or performed pursuant to the Clearinghouse Function
license granted in the Technology License; and (ii) refraining from: (a)
developing, promoting, or acquiring any technology directly competitive with
InterTrust Special Advanced Technologies or InterTrust Secure Container
technology (as such terms are defined in Exhibit F and Article 1, respectively,
of the Technology License) (the "Competitive Technology"); and (b) licensing
Competitive Technology, other than as necessary for clearing transactions
(collectively the "InterTrust Commitment").

          2.  Termination.  Notwithstanding paragraph 1 above, this Warrant
              -----------
shall terminate and be of no further force and effect upon the earlier of: (i)
the ten (10) year anniversary of the Grant Date; (ii) at the sole discretion of
the Company, upon the consummation of an underwritten public offering of the
Company's equity securities pursuant to a registration statement (an "IPO")
under the Securities Act of 1933, as amended (the "Act"), in which case this
Warrant shall be exercisable immediately prior to the consummation of the IPO at
a Warrant Price equal to the lower of $12.86 or the IPO Price (the "IPO Price"
shall be the initial "Price to Public" specified in the final prospectus with
respect to the IPO); and (iii) at the sole discretion of the Company, upon the
closing of (a) a sale of all or substantially all of the Company's assets or (b)
the merger or consolidation of the Company with another corporation whereby the
Company's stockholders immediately prior to such merger or consolidation will
hold less than 50% of the outstanding securities of the surviving corporation
immediately following such merger or consolidation (such sale, merger or
consolidation shall be referred to herein as a "Sale of the Company"), in which
case this Warrant shall be exercisable immediately prior to the consummation of
the Sale of the Company at a Warrant Price equal to the lower of $12.86 or the
value received for each share of Class B Common Stock in the Sale of the Company
(the "Sale Price"); provided, however that holder's right to exercise this
Warrant under subparagraphs 2(ii) and 2(iii) above at either Warrant Price is
subject to Holder's prior continuous InterTrust Commitment. If Holder (i)
exercises this Warrant at either the IPO Price or the Sale Price and (ii) has
not previously satisfied either Early Exercise Event, or within twenty-four (24)
months of the date the Company provides its SDK 1.0 product to the Holder under
the Technology License fails to satisfy either Early Exercise Event, then Holder
shall immediately remit to the Company or, in the case of the Sale of the
Company, to the successor company, an amount equal to the following:

          If this Warrant is exercised in connection with an IPO, the amount
equal to the product of multiplying (x) and (y) where:


<PAGE>
                                                                    CONFIDENTIAL


          (x)=the number of shares received upon exercise of this Warrant; and

          (y)=the difference between $12.86 and the IPO Price.

          If this Warrant is exercised in connection with a Sale of the Company,
the amount equal to the product of multiplying (x) and (y) where:

          (x)=the number of shares received upon exercise of this Warrant; and

          (y)=the difference between $12.86 and the Sale Price.

          3.  Number of Shares.  Subject to the terms and conditions hereinafter
              ----------------
set forth, the Holder is entitled, upon surrender of this Warrant, to purchase
One Hundred Fifty-Five Thousand Five Hundred Eight (155,508) shares of Class B
Common Stock from the Company.

          4.  Method of Exercise; Net Issue Exercise.
              --------------------------------------

              a.  Method of Exercise; Payment; Issuance of New Warrant.  The
                  ----------------------------------------------------
purchase right represented by this Warrant may be exercised by the Holder, in
whole or in part, from time to time at the election of the Holder, by the
surrender of this Warrant (with the notice of exercise form attached hereto as
Exhibit A duly executed) at the principal office of the Company and by the
---------
payment to the Company, by check, of an amount equal to the then applicable
Warrant Price per share multiplied by the number of Shares then being purchased.
A new warrant for the remaining purchase rights will be issued if the Warrant is
exercised in part.  The person or persons in whose name(s) any certificate(s)
representing Shares shall be issuable upon exercise of this Warrant shall be
deemed to have become the holder(s) of record of, and shall be treated for all
purposes as the record holder(s) of, the shares represented thereby (and such
shares shall be deemed to have been issued) immediately prior to the close of
business on the date or dates upon which this Warrant is exercised.  In the
event of any exercise of the rights represented by this Warrant, certificates
for the shares of stock so purchased shall be delivered to the Holder as soon as
possible and in any event within thirty (30) days of receipt of such notice and,
unless this Warrant has been fully exercised or expired, a new warrant
representing the portion of the Shares, if any, with respect to which this
Warrant shall not then have been exercised shall also be issued to the Holder as
soon as possible and in any event within such thirty (30)-day period.


              b.  Net Issue Exercise.  In lieu of exercising this Warrant
                  ------------------
pursuant to subparagraph 4(a) above and subject to the Company's prior written
consent, the Holder may elect to receive shares equal to the value of this
Warrant (or the portion thereof being canceled) by surrender of this Warrant at
the principal office of the Company together with notice of such election in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                               X=Y(A-B)
                                 ------
                                   A

      Where:      X=    The number of Shares to be issued to the Holder.


                                       3

<PAGE>

                                                                    CONFIDENTIAL


              Y=    the number of Shares purchasable under this Warrant (or the
                    portion thereof being canceled) at the time of such
                    exercise.

              A=    the fair market value of one share of Class B Common Stock
                    at the time of such exercise.

              B=    Warrant Price (as adjusted to the date of such calculation).

For purposes of this subparagraph 4(b), the fair market value of the Class B
Common Stock shall be determined as follows:

                    (i)    if this Warrant is exercised prior to an initial
public offering of the Company's Common Stock, the fair market value of the
Class B Common Stock shall be determined by the Company's Board of Directors;

                    (ii)   if the exercise is in connection with an initial
public offering of the Company's Common Stock, and if the Company's registration
statement relating to such public offering has been declared effective by the
Securities and Exchange Commission ("SEC"), then the fair market value per share
shall be the initial "Price to Public" specified in the final prospectus with
respect to the offering; or

                    (iii)  if this Warrant is exercised after, and not in
connection with, the Company's initial public offering, and:

                           (a)  if traded on a securities exchange, the fair
              market value shall be deemed to be the average of the closing
              prices over the ten (10) day trading period immediately preceding
              three days before the day the current fair market value of the
              securities is being determined; or

                           (b)  if actively traded over-the-counter, the fair
              market value shall be deemed to be the average of the closing bid
              and asked prices quoted on the Nasdaq system (or similar system)
              over the ten (10) day trading period immediately preceding three
              days before the day the current fair market value of the
              securities is being determined.

          5.  Stock Fully Paid; Reservation of Shares. All Shares that may be
              ---------------------------------------
issued upon the exercise of the rights represented by this Warrant shall, upon
issuance, be fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof. During the period within which the
rights represented by the Warrant may be exercised, the Company will at all
times have authorized and reserved for the purpose of issuance upon exercise of
the purchase rights evidenced by this Warrant, a sufficient number of shares of
Class B Common Stock to provide for their exercise of the right represented by
this Warrant.

          6.  Adjustment of Warrant Price and Number of Shares. The number and
              -----------------------------------------------
kind of securities purchasable upon the exercise of the Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the occurrence of
certain events as follows:
<PAGE>

                                                                    CONFIDENTIAL


              a.   Reclassification.  In case of any reclassification, change or
                   ----------------
conversion of Class B Common Stock issuable upon exercise of this Warrant (other
than a change in par value, or from par value to no par value, or from no par
value to par value, or as a result of a subdivision or combination), the Company
shall execute a  new Warrant (in form and substance satisfactory to the Holder,
as the holder of this Warrant) providing that the Holder shall have the right to
exercise such new Warrant and upon such exercise to receive, in lieu of each
share of Class B Common Stock theretofore issuable upon exercise of this
Warrant, the kind and amount of shares of stock, other securities, money and
property receivable upon such reclassification or change by a holder of one
share of Class B Common Stock.  Such new Warrant shall provide for adjustments
that shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Paragraph 6.  The provisions of this subparagraph 6(a)
shall similarly apply to successive reclassifications or changes.

              b.   Subdivisions or Combination of Shares.  If the Company at any
                   -------------------------------------
time while this Warrant remains outstanding and unexpired shall subdivide or
combine its Class B Common Stock, the Warrant Price and the number of shares of
Class B Common Stock issuable upon exercise hereof shall be proportionately
adjusted such that the aggregate exercise price of this Warrant shall at all
times remain equal.

              c.   Dividends.  If the Company at any time prior to the
                   ---------
expiration of this Warrant shall pay a dividend with respect to the Company's
Class B Common Stock payable in shares of Class B Common Stock, or make any
distribution with respect to the Company's Class B Common Stock, then the
purchase price per share shall be appropriately decreased, and the number of
Shares shall be appropriately increased in proportion to such dividend.

              d.   Merger or Consolidation.  Subject to Paragraph 2 above, upon
                   -----------------------
a Sale of the Company, the Company, or such successor or purchasing corporation,
as the case may be, shall execute a new Warrant (in form and substance
satisfactory to the Holder) providing that the HOlder shall have the right to
exercise such new Warrant and upon such exercise to receive, in lieu of each
share of Class B Common Stock theretofore issuable upon exercise of this
Warrant, the kind and amount of shares of stock, other securities, money and
property receivable upon such merger or consolidation by a holder of one share
of Class B Common Stock. Such new Warrant shall provide for adjustments that
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Paragraph 6. The provisions of this subparagraph 6(d) shall
similarly apply to successive mergers and consolidations.

              e.   No Impairment.  The Company will not, by amendment of its
                   -------------
Restated Certificate of Incorporation or through any reorganization,
recapitalization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in the
carrying out of all the provisions of this Paragraph 6 and in the taking of
all such action as may be necessary or appropriate in order to protect the
rights of the Holder as the holder of this Warrant against impairment.

                                                                    CONFIDENTIAL

              f.   Notices of Record Date.  In the event of any taking by the
                   ----------------------
Company of a record of its stockholders for the purpose of determining
stockholders who are entitled to receive payment of any dividend (other than a
cash dividend) or other distribution, any right to subscribe for, purchase or
otherwise acquire any share of any class or any other securities or property, or
to receive any other right, or any proposed liquidation, dissolution or winding
up of the Company, the Company shall mail to the Holder, as the holder of the
Warrant, at least twenty (20) days prior to the date specified therein, a notice
specifying the date on which any such record is to be taken for the purpose of
such dividend, distribution or right, and the amount and character of such
dividend, distribution or right.

              g.   Automatic Conversion.  Upon the consummation of an IPO, each
                   ---------------------
share issued upon exercise of this Warrant shall automatically convert into one
share (subject to stock splits and combinations as permitted by this Warrant) of
the securities issued in the IPO.

          7.  Notice of Adjustments. Whatever the Warrant Price shall be
              ---------------------
adjusted pursuant to the provisions hereof, the Company shall within twenty (20)
days of such adjustment deliver a certificate signed by its chief financial
officer to the Holder as the registered holder hereof setting forth, in a
reasonable detail, the event requiring the adjustment, the amount of the
adjustment, the method by which such adjustment was calculated, and the Warrant
Price after giving effect to such adjustment.

          8.  Right of First Refusal:  Restriction on Transfer.
              ------------------------------------------------

              a.   Grant.  The Company is hereby granted the right of first
                   -----
refusal (the "First Refusal Right"), exercisable in connection with any proposed
transfer of the shares.  For purposes of this Paragraph 8, the term "transfer"
shall include any sale, assignment, pledge, encumbrance or other disposition for
value of the shares intended to be made by the Holder; provided, however, that
the Holder may transfer any Shares to an investment fund or funds managed by
Holder or an affiliate of Holder (a "Permitted Transferee"), and provided that
Holder submits to the Company an irrevocable joint and several undertaking for
the benefit of the Company executed by the Holder or an affiliate of Holder and
the Permitted Transferee(s) that Holder or an affiliate of Holder may represent
the Permitted Transferee(s) on all matters related to the Shares, without first
making such an offer to the Company.

              b.   Notice of Intended Disposition.  In the event the Holder
                   -----------------------------
desires to accept a bona fide third-party offer for any or all of the shares
(the shares subject to such offer to be hereinafter call the "Target Shares"),
Holder shall promptly deliver to the Corporate Secretary of the Company written
notice (the "Disposition NOtice") in accordance with this Warrant of the terms
and conditions of the offer, including the purchase price and the identity of
the third-party offeror.

              c.   Exercise of Right.  The Company (or its assignees) shall, for
                   -----------------
a period of thirty (30) days following receipt of the Disposition Notice, have
the right to repurchase all but not less than all of the Target Shares specified
in the Disposition Notice upon substantially the same terms and conditions
specified therein.  Such right shall be exercisable by delivery of written
notice (the "Exercise Notice") in accordance with this Warrant to Holder prior
to the


















<PAGE>

                                                                    CONFIDENTIAL

expiration of the thirty (30) day exercise period.  If the First Refusal Right
is exercised with respect to the Target Shares specified in the Disposition
Notice, then the Company (or its assignees) shall effect the repurchase of the
Target Shares, including payment of the purchase price, not more than fifteen
(15) business days after delivery of the Exercise Notice; and at such time
Holder shall deliver to the Company the certificates representing the Target
Shares to be repurchased, each certificate to be properly endorsed for transfer.

          d.  Non-Exercise of Right.  In the event that Exercise Notice is not

                   -----------------
that Holder is acquiring this Warrant, and any Shares issued upon exercise of
this Warrant, for Holder's own account and not with a view to their resale or
distribution.

               b.  Exempt from Registration.  Holder acknowledges that this
                   ------------------------
Warrant has not been registered under the Act on the ground that the issuance
of this Warrant is exempt from registration pursuant to Section 4(2) of the Act,
and that the Company's reliance on such exemption is predicated on the
representations of Holder set forth herein.

               c.  Investment Experience.  In connection with the investment
                   ---------------------
representations made herein Holder represents that it is able to fend for itself
in the transactions contemplated by this Warrant, has such knowledge and
experience in financial and business matters as to be capable of evaluating the
merits and risks of its investment, has the ability to bear the economic risks
of its investment, and has been furnished with and has had access to such
information as it has requested and deemed appropriate to its investment
decision.

                   ---------------------
has been informed that this Warrant, and the Shares issued upon exercise of this
Warrant, are restricted securities under the Act and may not be resold or
transferred unless this Warrant, and the Shares issued upon exercise of this
Warrant, are first registered under the federal securities laws or unless an
exemption from such registration is available.  Accordingly, Holder hereby
acknowledges that Holder is prepared to hold this Warrant, and the Shares issued
upon exercise of this Warrant, for an indefinite period and that Holder is aware

not presently available to exempt the issuance of this Warrant from the
registration requirements of the Act.

               of the Purchased Shares under the Act, or (ii) all appropriate
               action necessary for compliance with the registration
               requirements of the Act or of any exemption from registration
               available under the Act (including Rule 144) has been taken.

consideration for said information being provided to Recipient, Recipient agrees
to be bound by the terms of this Agreement.

     (b)  InterTrust wishes to protect the InterTrust Top Secret Information
from unauthorized use and disclosure.  Disclosure of InterTrust Top Secret

     (b)  Notwithstanding the foregoing, Recipient shall be entitled to disclose
Top Secret Information pursuant to a court order issued by a court of competent
jurisdiction or as otherwise required by law; provided that Recipient shall
provide prompt advance notice thereof to InterTrust to enable InterTrust to seek
a protective order or otherwise prevent such disclosure and shall disclose no
more than the minimum information required by such court order or by law.

in such court, the Commonwealth courts in Alexandria, Virginia.  The parties
consent to the personal and exclusive jurisdiction and venue of such court and
waive any argument that jurisdiction or venue in such court is improper or
inconvenient.

6.   Severability.  If any provision or portion thereof in this Agreement shall
be found or be held to be illegal, invalid or unenforceable in any jurisdiction
in which this Agreement is being performed, then this Agreement shall
nevertheless be given full force and effect without said provision or portion.
