                             MICROSOFT CORPORATION
                       XBOX PUBLISHER LICENSE AGREEMENT

This License Agreement (the "Agreement") is entered into and effective as of
October 12, 2000 (the "Effective Date") by and between Microsoft Corporation, a
Washington corporation ("Microsoft"), and INTERPLAY ENTERTAINMENT CORP.
("Licensee").

     A.  Whereas, Microsoft develops and licenses a computer game system, known
as the Xbox game system; and

     B.  Whereas, Licensee is an experienced publisher of software products that
wishes to develop and/or publish one or more software products running on the
Xbox game system, and to license proprietary materials from Microsoft, on the
terms and conditions set forth herein.

Accordingly, for and in consideration of the mutual covenants and conditions
contained herein, and for other good and valuable consideration, receipt of
which each party hereby acknowledges, Microsoft and Licensee agree as follows:

1.  DEFINITIONS.  For the purposes of this Agreement, the following terms will
have the respective indicated meanings.

     1.1  "Art & Marketing Materials" shall mean art and mechanical formats for
a Software Title including the retail packaging, end user instruction manual
with end user license agreement and warranties, Finished Product Unit media
label, and any promotional inserts and other materials that are to be included
in the retail packaging, as well as all press releases, marketing, advertising
or promotional materials related to the Software Title and/or Finished Product
Units (including without limitation web advertising and Licensee's web pages to
the extent they refer to the Software Title(s) or the Finished Product Units).

     1.2  "Authorized Replicator" shall mean a software replicator certified and
approved by Microsoft for replication of games that run on Xbox.  Upon
Licensee's written request, Microsoft will provide Licensee with a copy of the
then-current list of Authorized Replicators, but the status of a particular
replicator and such list may change from time to time in Microsoft's sole and
absolute discretion.

     1.3  "Branding Specifications" shall mean the specifications in Exhibit C,
and such other design specifications as Microsoft may hereafter provide from
time to time, for using the Licensed Trademarks on a Software Title and/or on
related product packaging, documentation, and other materials.

     1.4  "Commercial Release" shall mean (a) with respect to Xbox, the first
distribution of an Xbox to the public for payment, and (b) with respect to a
Software Title, the earlier of the first distribution of the Software Title for
payment or distribution of Finished Product Units that are not designated as
beta or prerelease versions.

     1.5  "Finished Product Unit" shall mean a DVD-9 copy, in software object
code only, of a Software Title, in whole or in part.

     1.6  "Licensed Trademarks" shall mean the Microsoft trademarks depicted in
Exhibit B (which Microsoft unilaterally may modify from time to time during the
term of this Agreement upon written notice to Licensee).

                                       1

     1.7  "Software Title" shall mean the single software product as described
in the applicable Exhibit A (i.e., Exhibit A-1, Exhibit A-2, or Exhibit A-n, as
the case may be), developed by Licensee, and running on Xbox.  A Software Title
shall include the improvements and patches thereto (if and to the extent
approved by Microsoft), but shall not include any "prequel," "sequel," or add-on
pack.  If Microsoft approves one or more additional concept(s) for another
single software product proposed by Licensee to run on Xbox (including, without
limitation, new software titles or prequels, sequels, or add-on packs to
previously approved Software Titles), pursuant to the procedure set forth in
Section 2.1.1 below and the Xbox Guide (as defined in Section 2.1), then upon
Microsoft's written approval of such concept, this Agreement, and the term
"Software Title," shall be broadened automatically to cover the respective new
software product and the parties will prepare, initial and append to this
Agreement a new Exhibit A-n for each such additional new software product.

     1.8  "Certification Requirements" shall mean the requirements specified in
this Agreement (including without limitation the Xbox Guide) for quality,
compatibility, and/or performance of a Software Title, and, to the extent not
inconsistent with the foregoing standards, the standards of quality and
performance generally accepted in the console game industry.

     1.9  "Territory" shall be determined on a Software Title-by-Software Title
basis, and shall mean such countries as may be specified in writing by Microsoft
when the concept of the applicable Software Title is approved pursuant to
Section 2.1.1 below.

     1.10  "Xbox" shall mean the first version (as of the Commercial Release) of
Microsoft's Xbox game system, including operating system software and hardware
design specifications.

2.  DEVELOPMENT; DELIVERY; APPROVAL

     2.1  Software Title Development.  Licensee's development activities with
respect to each Software Title shall be in accordance with the development
schedule set forth in the applicable Exhibit A-n.  Furthermore, Licensee agrees
to be bound by all provisions contained in the then-applicable version of the
"Xbox Guide", the current version of which Microsoft or its affiliate will
deliver to Licensee when it is completed, after the execution of this Agreement.
Licensee understands and agrees that Microsoft may, in its discretion,
supplement, revise and update the Xbox Guide from time to time and that upon
Licensee's receipt of the applicable supplement, revision or updated version,
Licensee automatically shall be bound by all provisions of the then-current Xbox
Guide; Microsoft will specify in each such supplement, revision or updated
version a reasonable effective date of each change if such change or revision is
not required to be effective immediately.  If Licensee proceeds with the
development of a Software Title, Licensee shall deliver each milestone (i.e.,
Concept milestone as described in Section 2.1.1, optional Preliminary Version
milestones(s) as described in Section 2.1.2, Feature-Complete Version milestone
as described in Section 2.1.3, and Final Release Version milestone as described
in Section 2.1.4) to Microsoft for approval in writing, and Microsoft agrees to
use good faith efforts to promptly review each milestone and render its
approvals or rejections thereof within a reasonable period of time.  All
certification and playtesting (and applicable fees therefor, if any) will be in
accordance with the then-applicable version of the Xbox Guide.  If Microsoft
does not approve Licensee's submission for a given milestone then Licensee shall
either correct the problems that contributed to the lack of approval or, if
Microsoft gives Licensee written notice to cease development, Licensee shall
immediately cease all development activities for the applicable Software Title's
subsequent milestones.  Each successive milestone shall comply in all material
respects with the characteristics of previously approved milestones.  Each
software milestone shall be delivered in compiled object code form.

     2.1.1  Concept.  Licensee shall deliver to Microsoft a written and
completed concept submission form (in the form provided by Microsoft to
Licensee), including without limitation: (a) a detailed description of the
Software Title, including but not limited to (to the extent applicable) title,
theme, plot, characters, play elements, and technical specifications; (b) the
identities of any proposed subcontractors, and general information about the
principal team of individual developers, and (c) an

                                       2
<PAGE>

explanation of the design, technical and marketing suitability of the Software
Title. Evaluation of the proposed design will be based on criteria including,
but not necessarily limited to, the following: (i) originality; (ii) play
breadth and depth; (iii) playability; (iv) replayability and long-term interest;
and (v) theme, characters and storyline. Technical evaluation of the concept
will be based on criteria including, but not necessarily limited to, feasibility
of execution and usage of system capabilities (such as graphics, audio, hard
drive, play control, online capabilities and peripherals). Marketing suitability
will be evaluated based on criteria including, but not necessarily limited to,
the following: (i) market viability; (ii) Licensee's marketing commitment (if
any); (iii) suitability to the target demographic; and (iv) overall fit with the
Xbox certified software products portfolio.

     2.1.2  Preliminary Versions.  Licensee may, but will not be required to,
deliver to Microsoft certain preliminary versions of the Software Title, as
addressed in the Xbox Guide.

     2.1.3  Feature-Complete Version.  Licensee shall deliver to Microsoft a
feature-complete version of the Software Title (the "Beta Version"), which
includes all features of the Software Title and such other content as may be
required under the Xbox Guide.  Concurrently with delivery of the Beta Version,
Licensee will disclose in writing to Microsoft the details about any and all so-
called "hidden characters," "cheats," "easter eggs," "bonus video and/or audio,"
and similar elements included in the Beta Version and/or intended to be included
in the final release version of the Software Title.

     2.1.4  Final Release Version.  Licensee shall deliver to Microsoft,
Licensee's proposed final release version of the applicable Software Title that
is complete and ready for manufacture and commercial distribution, with the
final content rating certification, with identified program errors corrected,
and with any and all changes previously requested by Microsoft implemented.
However, nothing herein will be deemed to relieve Licensee of its obligation to
correct program bugs and errors, whenever discovered (including without
limitation after Commercial Release), and Licensee agrees to correct such bugs
and errors as soon as possible after discovery (provided that, with respect to
bugs or errors discovered after Commercial Release of the applicable Software
Title, the parties will mutually agree to an appropriate fix and timetable for
the correction of the bug/error in all Finished Product Units manufactured after
discovery).  In addition, Licensee will comply with all certification
procedures, guidelines and standards set forth in the then-applicable version of
the Xbox Guide. Licensee shall not distribute the Software Title, nor
manufacture any Finished Product Units intended for distribution, unless and
until Microsoft shall have given its final certification and approval of the
final release version of the Software Title, and Microsoft shall have provided
the code for the final release version to the applicable Authorized
Replicator(s).

     2.1.5  Playtesting.  Microsoft will playtest the Beta Version and proposed
final release version of each Software Title; if Licensee delivers preliminary
versions of a Software Title, Microsoft may (but will not be obligated to)
playtest such versions.  Microsoft will provide written comments to Licensee
regarding the results of its playtest results, and Licensee shall comply with
any reasonable requests made by Microsoft to improve the applicable Software
Title based on such playtest results.  Licensee acknowledges that,
notwithstanding its receipt of approvals from Microsoft for prior milestones or
versions during the development process, Licensee's proposed final release
version of each Software Title must be approved by Microsoft, as set forth in
the Xbox Guide.  In addition to conforming with the approved concept, with all
technical specifications, and with all other requirements set by Microsoft
during the development and approval process, each Software Title must achieve a
satisfactory rating in final playtesting.  Notwithstanding anything to the
contrary contained herein, Licensee acknowledges and understands that, in part,
the results of playtesting will be subjective, that Microsoft will have the
right to deny final approval based on its determination, and that Licensee has
and will have no expectation of final approval of any Software Title regardless
of any approvals or assessments given or made by Microsoft, informally or
formally, at any time.

     2.1.6  Art & Marketing Materials.  Licensee shall deliver to Microsoft for
approval all Art & Marketing Materials as and when developed, whether during
development activities or thereafter.

                                       3
<PAGE>

Licensee shall not distribute any specific Art & Marketing Materials unless and
until Microsoft shall have given its final certification and approval of the
specific item. Microsoft agrees to use good faith efforts to promptly review
each submission and render its approvals or rejections thereof within a
reasonable period of time. Microsoft further agrees that if it approves any
particular Art & Marketing Materials, then subsequent uses of substantially
similar Art & Marketing Materials in substantially similar contexts shall
require no additional approvals.

     2.2  Content Rating.  Licensee understands and agrees that, without
limitation, Microsoft will not give final certification and approval of a
Software Title unless and until Licensee shall have obtained, at Licensee's sole
cost, a rating of no higher than "Mature (17+)" or its equivalent from the
appropriate rating bodies for the applicable Territory (such as, ESRB, ELSPA,
etc.) and/or any and all other independent content rating authority/authorities
reasonably designated by Microsoft.  Licensee shall make any changes to the
Software Title required to obtain a rating of no higher than "Mature (17+)" (or
its equivalent).  In no event shall Licensee distribute any Software Title under
an "Adults Only" or higher rating (or equivalent rating).  Licensee shall
include the applicable rating(s) prominently on Finished Product Units, in
accordance with the applicable rating body guidelines.

     2.3  Development Kit License.  Microsoft or its affiliate will offer to
Licensee the opportunity to enter into one or more development kit license(s)
(each an "XDK License") pursuant to which Microsoft would license to Licensee
software development tools and hardware to assist Licensee in the development of
Software Titles, including without limitation certain sample code and other
redistributable code which Licensee could incorporate into Software Titles, on
such terms and conditions as are contained in the XDK License.

     2.4  Subcontractors.  Licensee shall not use any subcontractors or any
other third parties to perform software development work in connection with a
Software Title unless and until (i) the proposed subcontractor or other third
party and (ii) Microsoft shall have executed an XDK license; provided that
nothing contained herein will be deemed to require Microsoft or its affiliate to
execute an XDK License with any particular person or entity if Microsoft or its
affiliate determines that it is not appropriate to execute such an XDK License.

     2.5  Changes of Requirements by Microsoft.  Unless otherwise reasonably
specified by Microsoft at the respective time: (a) after approval by Microsoft
of the Beta Version of a Software Title, Licensee will not be obligated to
comply, with respect to such Software Title only, with any subsequent changes
made by Microsoft to the technical or content requirements for Software Titles
generally in the Xbox Guide; and (b) subject to the immediately preceding clause
(a), any changes made by Microsoft in Branding Specifications or other
requirements after final certification of a Software Title by Microsoft will be
effective as to such Software Title only on a "going forward" basis (i.e., only
to such Art & Marketing Materials and/or Finished Product Units as are
manufactured after Microsoft notifies Licensee of the change), unless (i) the
change can be accommodated by Licensee with insignificant added expense, or (ii)
Microsoft pays for Licensee's direct, out-of-pocket expenses necessarily
incurred as a result of its retrospective compliance with the change.

3.  RIGHTS AND RESTRICTIONS

     3.1  Trademarks.

     3.1.1  License.  In each Software Title, and on each Finished Product Unit
(and the packaging therefor), Licensee shall incorporate the Licensed Trademarks
and include credit and acknowledgement to Microsoft as set forth in the Branding
Specifications and the Xbox Guide.  Microsoft grants to Licensee a non-
exclusive, non-transferable, personal license to use the Licensed Trademarks,
according to the Branding Specifications and other conditions herein, and solely
in connection with marketing, sale, and distribution in the Territory of
Finished Product Units that meet the Certification Requirements.

                                       4
<PAGE>

     3.1.2  Limitations.  Licensee is granted no right, and shall not purport,
to permit any third party to use the Licensed Trademarks in any manner without
Microsoft's prior written consent.  Licensee's license to use Licensed
Trademarks in connection with the Software Title and Finished Product Units
shall not extend to the merchandising or sale of related or promotional products
under the Licensed Trademarks.

     3.1.3  Branding Specifications.  Licensee's use of the Licensed Trademarks
(including without limitation in Finished Product Unit and Art & Marketing
Materials) shall comply with the Branding Specifications in Exhibit C.  Licensee
shall not use Licensed Trademarks in association with any third party trademarks
in a manner that might suggest co-branding or otherwise create potential
confusion as to source or sponsorship of the Software Title or Finished Product
Units or ownership of the Licensed Trademarks.  Upon notice or other discovery
of any non-conformance with the requirements or prohibitions of this section,
Licensee shall promptly remedy such non-conformance and notify Microsoft of the
non-conformance and remedial steps taken.

     3.1.4  Certification Requirements.  Licensee may use the Licensed
Trademarks only in connection with the copies of the Software Title that meet
the Certification Requirements.  Licensee shall test the Software Title and
Finished Product Units for conformance with the Certification Requirements
according to generally accepted and best industry practices, and shall keep
written or electronic records of such testing during the term of this Agreement
and for no less than two (2) years thereafter ("Test Records").  Upon
Microsoft's request, Licensee shall provide Microsoft with copies of or
reasonable access to inspect the Test Records, Finished Product Units and
Software Title (either in pre-release or commercial release versions, as
Microsoft may request).  Upon notice or other discovery of any non-conformance
with the Certification Requirements, Licensee shall promptly remedy such non-
conformance in all Finished Product Units wherever in the chain of distribution
(subject to Sections 2.1.4 and 2.5 above), and shall notify Microsoft of the
non-conformance and remedial steps taken.

     3.1.5  Protection of Licensed Trademarks.  Licensee shall assist Microsoft
in protecting and maintaining Microsoft's rights in the Licensed Trademarks,
including preparation and execution of documents necessary to register the
Licensed Trademarks or record this Agreement, and giving immediate notice to
Microsoft of potential infringement of the Licensed Trademarks.  Microsoft shall
have the sole right to and in its sole discretion may commence, prosecute or
defend, and control any action concerning the Licensed Trademarks, either in its
own name or by joining Licensee as a party thereto.  Licensee shall not during
the Term of this Agreement contest the validity of, by act or omission
jeopardize, or take any action inconsistent with, Microsoft's rights or goodwill
in the Licensed Trademarks in any country, including attempted registration of
any Licensed Trademark, or use or attempted registration of any mark confusingly
similar thereto.

     3.1.6  Ownership.  Licensee acknowledges Microsoft's ownership of all
Licensed Trademarks, and all goodwill associated with the Licensed Trademarks.
Use of the Licensed Trademarks shall not create any right, title or interest
therein in Licensee's favor.  Licensee's use of the Licensed Trademarks shall
inure solely to the benefit of Microsoft.

     3.1.7  No Bundling with Unapproved Peripherals, Products or Software.
Licensee shall not market or distribute any Finished Product Unit bundled with a
peripheral product software or other products which Microsoft has not already
approved for commercial distribution as part of the Xbox program, nor shall
Licensee knowingly permit or assist any third party in such bundling, without
Microsoft's prior written consent.  For avoidance of doubt, Licensee may market
and distribute any Finished Product unit bundled with Microsoft-approved Xbox
peripheral product software or other products, so long as Licensee provides
Microsoft with written notice of its intention to do so within a reasonable
period of time in advance of any marketing or distribution thereof.

                                       5
<PAGE>

     3.2  EULA.  Licensee shall distribute (directly or indirectly) the Software
Title to end users subject to an end user license agreement ("EULA") in a form
to be approved by Microsoft prior to any distribution of the Software Title;
provided that, in any event, Licensee's EULA for the Software Title shall (a)
name Microsoft as a third party beneficiary, with the right to enforce the
agreement, (b) grant the end user the right to use the Software Title on only
one Xbox console at a time, and (c) forbid the end user from reverse engineering
or decompiling the Software Title or Xbox.  Microsoft will have the right to
modify its requirements for the EULA at any time, in its discretion, and
Licensee shall implement, at its sole cost, all such new requirements as soon as
reasonably possible after receiving written notice from Microsoft of such
required modifications.

     3.3  No Electronic Transmission; No Online Activities.  Licensee shall
distribute the Software Title only as embodied in Finished Product Units;
specifically, but without limitation, Licensee shall not distribute the Software
Title by any means of electronic transmission without the prior written approval
of Microsoft, which Microsoft may grant or withhold in its discretion.
Furthermore, Licensee will not authorize or permit any online activities
involving the Software Title, including without limitation multiplayer, peer-to-
peer and/or online play, without the prior written approval of Microsoft, which
Microsoft may grant or withhold in its discretion.

     3.4  No Distribution Outside the Territory.  Licensee shall distribute
Finished Product Units only in the Territory.  Licensee shall not directly or
indirectly export any Finished Product Units from the Territory nor shall
Licensee knowingly permit or assist any third party in doing so, nor shall
Licensee distribute Finished Product Units to any person or entity that it has
reason to believe may re-distribute or sell such Finished Product Units outside
the Territory.

     3.5  No Reproduction of Finished Product Units Except by Microsoft or
Authorized Replicators.  Licensee acknowledges that this Agreement does not
grant Licensee the right to reproduce or otherwise manufacture Finished Product
Units itself, or on its behalf, other than with Microsoft or an Authorized
Replicator.  Licensee must use Microsoft or an Authorized Replicator to produce
Finished Product Units, pursuant to Section 4.

     3.6  No Reverse Engineering.  Licensee may utilize and study the design,
performance and operation of Xbox solely for the purposes of developing the
Software Title.  Notwithstanding the foregoing, Licensee shall not, directly or
indirectly, reverse engineer or aid or assist in the reverse engineering of all
or any part of Xbox except and only to the extent that such activity is
expressly permitted by applicable law notwithstanding this limitation.  Reverse
engineering includes, without limitation, decompiling, disassembly, sniffing,
peeling semiconductor components, or otherwise deriving source code.  In
addition to any other rights and remedies that Microsoft may have under the
circumstances, Licensee shall be required in all cases to pay royalties to
Microsoft in accordance with Section 6 below with respect to any games or other
products that are developed, marketed or distributed by Licensee, and derived in
whole or in part from the reverse engineering of Xbox or any Microsoft data,
code or other material.

     3.7  Reservation of Rights. Microsoft reserves all rights not explicitly
granted herein.

     3.8  Ownership of the Software Titles.  Except for the intellectual
property supplied by Microsoft to Licensee (including without limitation the
licenses in the Licensed Trademarks hereunder and the licenses in certain
software and hardware granted by an XDK License), ownership of which is retained
by Microsoft, insofar as Microsoft is concerned, Licensee will own all rights in
and to the Software Titles.

4.  MANUFACTURING

     4.1  Approved Replicators.  Licensee shall retain only an Authorized
Replicator to manufacture all Finished Product Units.

                                       6
<PAGE>

     4.2  Terms of Use of Authorized Replicator.  Licensee will notify Microsoft
in writing of the identity of the applicable Authorized Replicator and unless
Microsoft agrees otherwise, the agreement for such manufacturing/replication
services shall be as negotiated by Licensee and the applicable Authorized
Replicator, subject to the following requirements:

     4.2.1  Microsoft, and not Licensee, will provide to the single applicable
Authorized Replicator the final release version of the Software Title and all
specifications required by Microsoft for the manufacture of the Finished Product
Units (including without limitation the Security Technology (as defined in
Section 4.4 below); Licensee will be responsible for preparing and delivering to
the Authorized Replicator all other items required for manufacturing Finished
Product Units; and Licensee agrees that all Finished Product Units must be
replicated in conformity with all of the quality standards and manufacturing
specifications, policies and procedures that Microsoft requires of its
Authorized Replicators, and that all so-called "adders" must be approved by
Microsoft prior to packaging (in accordance with Section 2.1.6 above);

     4.2.2  Microsoft will have the right, but not the obligation, to be
supplied with up to fifty (50) Finished Product Units (including pre-production
samples and random units manufactured during production runs) at Licensee's cost
but without royalties, for quality assurance and archival purposes;

     4.2.3  the initial manufacturing order for Finished Product Units of each
Software Title may not be less than a number specified by Microsoft in the Xbox
Guide; although such number may change from time to time during the term of this
Agreement, initially it will be 35,000;

     4.2.4  as between Licensee and Microsoft, Licensee shall be responsible for
ensuring that all Finished Product Units are free of all defects;

     4.2.5  Licensee will use commercially reasonable efforts to cause the
Authorized Replicator to deliver to Microsoft true and accurate monthly
statements of Finished Product Units manufactured in each calendar month, on a
Software Title-by-Software Title basis and in sufficient detail to satisfy
Microsoft, within fifteen (15) days after the end of the applicable month, and
Microsoft will have reasonable audit rights to examine the records of the
Authorized Replicator regarding the number of Finished Product Units
manufactured;

     4.2.6  Microsoft will have the right to have included in the packaging of
Finished Product Units such marketing materials for Xbox and/or other Xbox
products or services as Microsoft may determine in its reasonable discretion.
Microsoft will be responsible for delivering to the Authorized Replicator all
such marketing materials as it desires to include with Finished Product Units,
and any incremental insertion costs relating to such marketing materials will be
borne by Microsoft;

     4.2.7  Microsoft does not guarantee any level of performance by its
Authorized Replicators, and Microsoft will have no liability to Licensee for any
Authorized Replicator's failure to perform its obligations under any applicable
agreement between Microsoft and such Authorized Replicator and/or between
Licensee and such Authorized Replicator;

     4.2.8  Prior to placing an order with a replicator/manufacturer for
Finished Product Units, Licensee shall confirm with Microsoft that such entity
is an Authorized Replicator; Microsoft will endeavor to keep an up-to-date list
of Authorized Replicators in the Xbox Guide.  Licensee will not place any order
for Finished Product Units with any entity that is not at such time an
Authorized Replicator.

     4.3  Approval of New Authorized Replicator.  If Licensee requests that
Microsoft certify and approve a third party replicator that is not then an
Authorized Replicator, Microsoft will consider such request in good faith.
Licensee acknowledges and agrees that Microsoft may condition certification and
approval of such third party on the execution of an agreement in a form
satisfactory to Microsoft pursuant to which such third party agrees to strict
quality standards, non-disclosure requirements, license fees for

                                       7
<PAGE>

use of Microsoft intellectual property and trade secrets, and procedures to
protect Microsoft's intellectual property and trade secrets. Notwithstanding
anything contained herein, Licensee acknowledges that Microsoft is not required
to certify or approve any particular third party as an Authorized Replicator,
and that the certification and approval process may be time-consuming.

     4.4  Security.  Microsoft will have the right to add, at its own cost, to
the final release version of the Software Title delivered by Licensee to
Microsoft, and to all Finished Product Units, such digital signature technology
and other security technology and copyright management information
(collectively, "Security Technology") as Microsoft may determine to be
necessary, and/or Microsoft may modify the signature included in any Security
Technology included in the Software Title by Licensee at Microsoft's direction.
Additionally, Microsoft may add, at its own cost, Security Technology that
prohibits the play of Software Titles on Xbox units manufactured in a region or
country different from the location of manufacture of the respective Finished
Product Units.

                                       8

5.  MARKETING, SALES AND SUPPORT

     5.1  Licensee Responsible.  As between Microsoft and Licensee, Licensee
shall be solely responsible for marketing and sales of the Software Title, and
for providing technical and all other support to the end users of the Finished
Product Units.  Licensee will provide all end users of Software Titles contact
information (including without limitation Licensee's street address and
telephone number, and the applicable individual/group responsible for customer
support).  Such end user support will be consistent with the then-applicable
console game industry standards.  Licensee acknowledges and agrees that
Microsoft will have no support responsibilities whatsoever to end users of the
Software Title or with respect to Finished Product Units.

     5.2  Art & Marketing Materials.  In accordance with Section 2.1.6 above,
Licensee shall submit all Art & Marketing Materials to Microsoft, and Licensee
shall not distribute such Art & Marketing Materials unless and until Microsoft
has approved them in writing.  Prior to publication of any Art & Marketing
Materials, Licensee agrees to incorporate all changes relating to use of the
Licensed Trademarks that Microsoft may request, and will use its commercially
reasonable efforts to incorporate other changes reasonably suggested by
Microsoft (provided, however, that Licensee shall at all times comply with the
requirements set forth in the Branding Specifications and/or the Xbox Guide).

     5.3  Warranty.  Licensee shall provide the original end user of any
Finished Product Unit a minimum ninety (90) day limited warranty that the
Finished Product Unit will perform in accordance with its user documentation or
Licensee will provide a replacement Finished Product Unit at no charge.

     5.4  Recall.  Notwithstanding anything to the contrary contained in this
Agreement (including without limitation Section 2.1.4), in the event of a
material defect in a Software Title and/or any Finished Product Units, which
defect in the reasonable judgement of Microsoft would significantly impair the
ability of an end user to play such Software Title or Finished Product Unit,
Microsoft may require Licensee to recall Finished Product Units and undertake
prompt repair or replacement of such Software Title and/or Finished Product
Units.

     5.5  Software Title License.  Subject to third party rights of which
Licensee shall have informed Microsoft in writing at the time of delivery of the
feature-complete version of the applicable Software Title, Licensee hereby
grants to Microsoft a fully-paid, royalty-free, non-exclusive license (i) to
publicly perform the Software Titles at conventions, events, trade shows, press
briefings, and the like; and (ii) to use the title of the Software Title, and
screen shots from the Software Title, in advertising and promotional material
relating to Xbox and related Microsoft products and services, as Microsoft may
reasonably deem appropriate.  The parties agree to discuss in good faith a
variety of scenarios and contexts for which Licensee approves such public
performances and uses of the title of the Software Title and screenshots
therefrom, provided that nothing shall prevent or restrict Microsoft at any time

</TABLE>

Notwithstanding the foregoing, no royalties will be payable hereunder with
respect to any Demo Finished Product Units.  For the purposes hereof, a "Demo
Finished Product Unit" will mean a Finished Product Unit that (i) contains only
a small portion of the applicable Software Title, (ii) is provided to end users
only to advertise or promote the applicable Software Title (although it may
include demonstration versions of other games for Xbox published by Licensee),
(iii) is manufactured in a number of units that has been approved in advance by
Microsoft, which approval Microsoft agrees not to unreasonably withhold, and
(iv) is distributed free or with a suggested retail price of not more than
US$5.00.

     6.2  Royalty Payments.  Licensee shall have the option of paying the above
royalties in US Dollars, Japanese Yen or Euros, according to the terms of this
Section.  By designating the appropriate box below, Licensee may choose to pay
royalties on either a "Worldwide" or "Regional" basis.  Such designation shall
be binding throughout the term of this Agreement for all of Licensee's Software
Titles.  If Licensee elects to pay on a Worldwide basis, it shall pay royalties
in US Dollars regardless of where the Finished Product Units are distributed or
manufactured.  If Licensee elects to pay on a Regional basis, it shall pay
royalties in US Dollars, Japanese Yen or Euros in accordance with the table set
forth in Section 6.1 but subject to the rest of this Section 6.2:

     (i) If the Authorized Replicator manufacturing the Finished Product Units
is located in Japan, Singapore, Malaysia or Taiwan, Licensee shall pay its
royalty denominated in Japanese Yen for such Finished Product Units.

     (ii) If the Authorized Replicator manufacturing the Finished Product Units
is located in a member country of the European Union, Licensee shall pay its
royalty denominated in Euros for such Finished Product Units.

     (iii)  If the Authorized Replicator manufacturing the Finished Product
Units is located in any other country or region of the world, Licensee shall pay
its royalty denominated in US Dollars for such Finished Product Units.

Notwithstanding the foregoing, in the event the conversion ratio for either Yen
or Euros to Dollars, as described in the US edition of the Wall Street Journal,
falls outside the foreign exchange trading range as set forth in the chart
below, for a period of time greater than 30 consecutive days, Microsoft may then

                                       10
<PAGE>

readjust the royalty amounts set forth in Section 6.1 for that currency.  Such
readjustments shall be made in Microsoft's good faith discretion according to
its normal practices.

     6.3  Payment Process.  After its receipt from the applicable Authorized
Replicator(s) of each monthly statement of Finished Product Units manufactured,
Microsoft will invoice Licensee for the amount owed to Microsoft pursuant to
Section 6.1 above based upon the applicable statement.  Licensee shall pay to
Microsoft the full amount invoiced within thirty (30) calendar days after the
date of the respective invoice.  Payment will be made by wire transfer, in
immediately available funds, to an account, and in accordance with a reasonable
procedure, to be specified in writing by Microsoft.

     6.4  Audit. Licensee shall keep all usual and proper records related to its
performance (and any subcontractor's performance) under this Agreement,
including support for any cost borne by or income due to Microsoft, for a
minimum period of three (3) years from the date they are created.  Such records,
books of account, and entries shall be kept in accordance with generally
accepted accounting principles.  Microsoft reserves the right, upon twenty-four
(24) hours' notice, to audit Licensee's records and consult with Licensee's
accountants for the purpose of verifying Licensee's compliance with the terms of
this Agreement and for a period of two (2) years thereafter.  Any such audit
shall be made by Microsoft's internal audit team or any Microsoft designee, and
shall be conducted during regular business hours at the Licensee's (or any
applicable subcontractor's) offices.  Any such audit shall be paid for by
Microsoft unless material discrepancies are disclosed.  "Material" shall mean
five percent (5%) of the royalties due to Microsoft within the audit period.  If
material discrepancies are disclosed, Licensee agrees to pay Microsoft for the
costs associated with the audit, as well as reimburse Microsoft for all over-
charged amounts, plus interest at a rate of 12% per annum.

     6.5  Taxes.

     6.5.1  The royalties to be paid by Licensee to Microsoft herein do not
include any foreign, U.S. federal, state, local, municipal or other governmental
taxes, customs and other duties, levies, fees, excises or tariffs, arising as a
result of or in connection with the transactions contemplated under this
Agreement including, without limitation, any state or local sales or use taxes
or consumption tax or any value added tax or business transfer tax now or
hereafter imposed on the provision of goods and services to Licensee by
Microsoft under this Agreement, regardless of whether the same are separately
stated by Microsoft (all such taxes and other charges being referred to herein
as "Taxes").  All Taxes (and any penalties, interest, or other additions to any
Taxes), with the exception of taxes imposed on Microsoft's net income or with
respect to Microsoft's property ownership, shall be the financial responsibility
of Licensee.  Licensee agrees to indemnify, defend and hold Microsoft harmless
from any such Taxes or claims, causes of action, costs (including, without
limitation, reasonable attorneys' fees) and any other liabilities of any nature
whatsoever related to such Taxes.

     6.5.2  Licensee will pay all applicable value added, sales and use taxes
and other taxes levied on it by a duly constituted and authorized taxing
authority on the XDKs or any transaction related thereto in each country in
which the services and/or property are being provided or in which the
transactions contemplated hereunder are otherwise subject to tax, regardless of
the method of delivery.

                                       11
<PAGE>

Any taxes that are owed by Licensee, (i) as a result of entering into this
Agreement and the payment of the fees hereunder, (ii) are required or permitted
to be collected from Licensee by Microsoft under applicable law, and (iii) are
based upon the amounts payable under this Agreement (such taxes described in
(i), (ii), and (iii) above the "Collected Taxes"), shall be remitted by Licensee
to Microsoft, whereupon, upon request, Microsoft shall provide to Licensee tax
receipts or other evidence indicating that such Collected Taxes have been
collected by Microsoft and remitted to the appropriate taxing authority.
Licensee may provide to Microsoft an exemption certificate acceptable to
Microsoft and to the relevant taxing authority (including without limitation a
resale certificate) in which case, after the date upon which such certificate is
received in proper form, Microsoft shall not collect the taxes covered by such
certificate.

     6.5.3  If, after a determination by foreign tax authorities, any taxes are
required to be withheld, on payments made by Licensee to Microsoft, Licensee may
deduct such taxes from the amount owed Microsoft and pay them to the appropriate
taxing authority; provided however, that Licensee shall promptly secure and
deliver to Microsoft an official receipt for any such taxes withheld or other
documents necessary to enable Microsoft to claim a U.S. Foreign Tax Credit.
Licensee will make certain that any taxes withheld are minimized to the extent
possible under applicable law.

     6.5.4  This tax Section 6.5 shall govern the treatment of all taxes arising
as a result of or in connection with this Agreement notwithstanding any other
section of this Agreement.

7.  NON-DISCLOSURE; ANNOUNCEMENTS

     7.1  Non-Disclosure Agreement.  The information, materials and software
exchanged by the parties hereunder or under an XDK License, including the terms
and conditions hereof and of the XDK License, shall be subject to the Non-
Disclosure Agreement between the parties attached hereto and incorporated herein
by reference as Exhibit D.

     7.2  Public Announcements.  The parties contemplate that they will
coordinate the issuance of initial press releases, or a joint press release,
announcing the relationship established by the execution of this Agreement.
However, neither party shall issue any such press release or make any such
public announcement(s) without the express prior consent of the other party,
which consent will not be unreasonably withheld or delayed.  Furthermore, the
parties agree to use their commercially reasonable efforts to coordinate in the
same manner any subsequent press releases and public announcements relating to
their relationship hereunder prior to the issuance of the same.  Nothing
contained in this Section 7.2 will relieve Licensee of any other obligations it
may have under this Agreement, including without limitation its obligations to
seek and obtain Microsoft approval of Art & Marketing Materials.

     7.3  Required Public Filings.  Notwithstanding Sections 7.1 and 7.2, the
parties acknowledge that this Agreement, or portions thereof, may be required
under applicable law to be disclosed, as part of or an exhibit to a party's
required public disclosure documents.  If either party is advised by its legal
counsel that such disclosure is required, it will notify the other in writing
and the parties will jointly seek confidential treatment of this Agreement to
the maximum extent reasonably possible, in documents approved by both parties
and filed with the applicable governmental or regulatory authorities, and/or
Microsoft will prepare a redacted version of this Agreement for filing.

8.  TERM AND TERMINATION

     8.1  Term.  The term of this Agreement shall commence on the Effective Date
and unless terminated earlier as provided herein, shall continue until three (3)
years after Commercial Release of Xbox.

     8.2  Termination for Breach.  In the event either party shall materially
fail to perform or comply with this Agreement or any provision thereof, and fail
to remedy the default within fifteen (15) days after the receipt of notice to
that effect, then the other party shall have the right, at its sole option and

                                       12
<PAGE>

upon written notice to the defaulting party, to terminate this Agreement upon
written notice.  Any notice of default hereunder shall be prominently labeled
"NOTICE OF DEFAULT"; provided, however, that if the default is of Section 3 or
7.1 above, or an XDK License, then the non-defaulting party may terminate this
Agreement immediately upon written notice, without being obligated to provide a
fifteen-day cure period.  The rights and remedies provided in this Section shall
not be exclusive and are in addition to any other rights and remedies provided
by law or this Agreement.  If the uncured default is related to a particular
Software Title, then the party not in default will have the right, in its
discretion, to terminate this Agreement in its entirety or with respect to the
applicable Software Title.

     8.3  Termination for Creative Reasons.  In the event that Microsoft
determines, at any time prior to the Commercial Release of a Software Title,
that such Software Title does not comply with the requirements set forth in the
Xbox Guide, then Microsoft will have the right to terminate this Agreement,
without cost or penalty, upon written notice to Licensee solely with respect to
such Software Title, in Microsoft's sole discretion and notwithstanding any
prior approvals given by Microsoft pursuant to Section 2 above.

     8.4  Effect of Termination; Sell-off Rights.  Upon termination or
expiration of this Agreement, Licensee shall have no further right to exercise
the rights licensed hereunder or otherwise acquired in relation to this
Agreement and shall promptly return any and all copies of the Licensed
Trademarks.  Licensee shall have a period of six (6) months following expiration
of this Agreement, or termination for a reason other than Licensee's breach, to
sell-off its inventory of Finished Product Units existing as of the date of
termination or expiration, after which sell-off period Licensee immediately
shall destroy all Finished Product Units then in its possession or under its
control.  All of Licensee's obligations under this Agreement shall continue to
apply during such six-month sell-off period.  If this Agreement is terminated
due to Licensee's breach, Licensee shall immediately destroy all Finished
Product Units not yet distributed to Licensee's distributors, dealers and/or end
users.  If requested by Microsoft in writing, Licensee will deliver to Microsoft
the written certification by an officer of Licensee confirming the destruction
of Finished Product Units required hereunder.

     8.5  Survival.  The following provisions shall survive termination of this
Agreement: 1, 3.6, 5.1, 5.3, 5.4, 6, 7, 8.4, 8.5, 9, 10, 11 and 12.

     9.1.1  It has the full power to enter into this Agreement;

     9.1.2  It has not previously and will not grant any rights to any third

Materials (excluding those portions that consist of the Licensed Material,
Licensed Trademarks, and redistributable components of the so-called "XDK" in
the form as delivered to Licensee by Microsoft pursuant to an XDK License) do
not and will not infringe upon or misappropriate any third party trade secrets,
copyrights, trademarks, patents, publicity, privacy or other proprietary rights.

     9.2  Microsoft.  Microsoft warrants and represents that:

     9.2.1  It has the full power to enter into this Agreement; and

     9.3  DISCLAIMER.  EXCEPT AS EXPRESSLY STATED IN THIS SECTION 9, MICROSOFT
PROVIDES ALL MATERIALS (INCLUDING WITHOUT LIMITATION THE SECURITY TECHNOLOGY)
AND SERVICES HEREUNDER ON AN "AS IS" BASIS, AND MICROSOFT DISCLAIMS ALL OTHER
WARRANTIES UNDER THE APPLICABLE LAWS OF ANY COUNTRY, EXPRESS OR IMPLIED,
REGARDING THE MATERIALS AND SERVICES IT PROVIDES HEREUNDER, INCLUDING ANY
IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR
WARRANTY OF FREEDOM FROM COMPUTER VIRUSES.  WITHOUT LIMITATION, MICROSOFT
PROVIDES NO WARRANTY OF NON-INFRINGEMENT.

     9.4  LIMITATION OF LIABILITY. THE MAXIMUM LIABILTY OF MICROSOFT TO LICENSEE
OR ANY THIRD PARTY ARISING OUT OF THIS AGREEMENT SHALL BE THE TOTAL AMOUNTS
RECEIVED BY MICROSOFT HEREUNDER.  FURTHERMORE, UNDER NO CIRCUMSTANCES SHALL
MICROSOFT BE LIABLE TO LICENSEE FOR ANY DAMAGES WHATSOEVER WITH RESPECT TO ANY
CLAIMS RELATING TO THE SECURITY TECHNOLOGY AND/OR ITS AFFECT ON ANY SOFTWARE
TITLE.

10.  INDEMNITY

     10.1  Indemnification. A claim for which indemnity may be sought hereunder
shall be referred to as a "Claim."

     10.1.1  Mutual Indemnification.  Each party hereby agrees to indemnify,
defend, and hold the other party harmless from any and all claims, demands,
costs, liabilities, losses, expenses and damages (including reasonable
attorneys' fees, costs, and expert witnesses' fees) arising out of or in
connection with any claim that, taking the claimant's allegations to be true,
would result in a breach by the indemnifying party of any of its warranties and
covenants set forth in Section 9.

     10.1.2  Additional Licensee Indemnification Obligation.  Licensee further
agrees to indemnify, defend, and hold Microsoft harmless from any and all
claims, demands, costs, liabilities, losses, expenses and damages (including
reasonable attorneys' fees, costs, and expert witnesses' fees) arising out of or
in connection with any claim regarding any Software Title or Finished Product
Unit, including without limitation any claim relating to quality, performance,
safety or conformance with the Certification Requirements, or arising out of
Licensee's use of the Licensed Trademarks in breach of this Agreement.

     10.2  Notice and Assistance.  The indemnified party shall:  (i) provide the
indemnifying party reasonably prompt notice in writing of any Claim and permit
the indemnifying party to answer and defend such Claim through counsel chosen
and paid by the indemnifying party; and (ii) provide information, assistance and
authority to help the indemnifying party defend such Claim.  The indemnified
party may participate in the defense of any Claim at its own expense.  The
indemnifying party will not be responsible for any settlement made by the
indemnified party without the indemnifying party's written permission, which
will not be unreasonably withheld or delayed.  In the event the indemnifying
party and the indemnified party agree to settle a Claim, the indemnified party
agrees not to publicize the settlement without first obtaining the indemnifying
party's written permission.

     10.3  Insurance.  Prior to distribution of any Software Title, Licensee at
its sole cost and expense shall have endorsed Microsoft as an additional insured
on Licensee's media perils errors and omissions liability policy for claims
arising in connection with production, development and distribution of each
Software Title in an amount no less than $2,000,000 on a per occurrence or per
incident basis.  Coverage provided to Microsoft under the policy shall be
primary to and not contributory with any insurance maintained by Microsoft.
Upon request, Licensee agrees to furnish copies of the additional insured
endorsement and/or a certificate of insurance evidencing compliance with this
requirement.

11.  PROTECTION OF PROPRIETARY RIGHTS

     11.1  Microsoft Intellectual Property.  In the event Licensee learns of any
infringement or imitation of the Licensed Trademarks, or Microsoft's proprietary
rights in or related to the Software Title or the Finished Product Units, it
will promptly notify Microsoft thereof.  Microsoft may take such action as it
deems advisable for the protection of its rights in and to such proprietary
rights, and Licensee shall, if requested by Microsoft, cooperate in all
reasonable respects therein at Microsoft's expense.  In no event, however, shall
Microsoft be required to take any action if it deems it inadvisable to do so.
Microsoft will have the right to retain all proceeds it may derive from any
recovery in connection with such actions.

     11.2  Licensee Intellectual Property.  Licensee, without the express
written permission of Microsoft, may bring any action or proceeding relating to
any infringement of its own proprietary rights in or relating to the Software
Title or the Finished Product Units (provided that Licensee will not have the
right to bring any such action or proceeding involving Microsoft's intellectual
property).  Licensee shall make reasonable efforts to inform Microsoft regarding
such actions in a timely manner.  Licensee will have the right to retain all
proceeds it may derive from any recovery in connection with such actions.
Licensee agrees to use all commercially reasonable efforts to protect and
enforce its proprietary rights in the Software Title.

     11.3  Joint Actions.  Licensee and Microsoft may agree to jointly pursue
cases of infringement involving the Software Titles (since such products will
contain intellectual property owned by each of them).  Unless the parties
otherwise agree, or unless the recovery is expressly allocated between them by
the court (in which case the terms of Sections 11.1 and 11.2 will apply), in the
event Licensee and Microsoft jointly prosecute an infringement lawsuit under
this provision, any recovery shall be used first to reimburse Licensee and
Microsoft for their respective reasonable attorneys' fees and expenses, pro
rata, and any remaining recovery shall also be given to Licensee and Microsoft
pro rata based upon the fees and expenses incurred in bringing such action.

12.  GENERAL

     12.1  Governing Law; Venue; Attorneys Fees. This Agreement shall be
construed and controlled by the laws of the State of Washington, U.S.A., and
Licensee consents to exclusive jurisdiction and venue in the federal courts
sitting in King County, Washington, U.S.A., unless no federal jurisdiction
exists, in which case Licensee consents to exclusive jurisdiction and venue in
the Superior Court of King County, Washington, U.S.A.  Licensee waives all
defenses of lack of personal jurisdiction and forum non conveniens.  Process may
be served on either party in the manner authorized by applicable law or court
rule.  If either party employs attorneys to enforce any rights arising out of or
relating to this Agreement, the prevailing party shall be entitled to recover
its reasonable attorneys' fees, costs and other expenses, but excluding the
prevailing party's in-house counsel costs and expenses.  This choice of
jurisdiction provision does not prevent Microsoft from seeking injunctive relief
with respect to a violation of intellectual property rights or confidentiality
obligations in any appropriate jurisdiction.

     12.2  Notices; Requests.  All notices and requests in connection with this
Agreement shall be deemed given as of the day they are (i) received in the U.S.
mails, postage prepaid, certified or registered, return receipt requested; or
(ii) sent by overnight courier, charges prepaid, with a confirming fax; and
addressed as follows:

     12.6  Injunctive Relief.  The parties agree that Licensee's threatened or
actual unauthorized use of the Licensed Trademarks whether in whole or in part,
may result in immediate and irreparable damage to Microsoft for which there is
no adequate remedy at law, and that either party's threatened or actual breach
of the confidentiality provisions may cause like damage to the nonbreaching
party, and in such event the nonbreaching party shall be entitled to appropriate
injunctive relief, without the necessity of posting bond or other security.

                            BRANDING SPECIFICATIONS

The following guidelines apply whenever Licensee places a copy of any Licensed
Trademark on the Software Title, or related collateral materials.

     .  Licensee may use the Licensed Trademarks solely on the retail box,
        documentation, and Art & Marketing Materials for the Software Title,
        and in no other manner.

     .  Licensee's name, logo, or trademark must appear on any materials where
        the Licensed Trademarks are used, and must be larger and more prominent
        than the Licensed Trademarks.

     .  The Licensed Trademarks may not be used in any manner that expresses or
        might imply Microsoft's affiliation, sponsorship, endorsement,
        certification, or approval, other than as contemplated by this
        Agreement.

     .  The Licensed Trademarks may not be included in any non-Microsoft trade
        name, business name, domain name, product or service name, logo, trade
        dress, design, slogan, or other trademark.

     .  Licensee may use the Licensed Trademarks only as provided by Microsoft
        electronically or in hard copy form. Except for size subject to the
        restrictions herein, the Licensed Trademarks may not be altered in any
        manner, including proportions, colors, elements, etc., or animated,
        morphed, or otherwise distorted in perspective or dimensional
        appearance.

     .  The Licensed Trademarks may not be combined with any other symbols,
        including words, logos, icons, graphics, photos, slogans, numbers, or
        other design elements.

     .  The Licensed Trademarks (including but not limited to Microsoft's logos,
        logotypes, trade dress, and other elements of product packaging and web
        sites) may not be imitated.

     .  The Licensed Trademarks may not be used as a design feature in any
        materials.

     .  The Licensed Trademarks must stand alone. A minimum amount of empty
        space must surround the Licensed Trademarks separating it from any other
        object, such as type, photography, borders, edges, and so on. The
        required area of empty space around the Licensed Trademarks must be
        1/2x, where x equals the height of the Licensed Trademarks.

     .  Each use of the Licensed Trademarks must include the notice: "Xbox is a
        trademark of Microsoft Corporation in the United States and/or other
        countries and is used under license from Microsoft".

Additional guidelines for proper use of the "Xbox" word mark:

     .  Use the trademark symbol ("(TM)") at the upper right corner or baseline
        immediately following the name "Xbox". This symbol should be used at the
        first or most prominent mention. Please be sure to spell Xbox as one
        word, with no hyphen and with no space between "X" and "box".

     .  Include the following notice on materials referencing Xbox:

            "Xbox is a trademark of Microsoft Corporation."

     .  Trademarks identify a company's goods or services. Xbox is not a generic
        thing, but rather a brand of game system from Microsoft. A trademark is
        a proper adjective that modifies the generic name or descriptor of a
        product or service. The descriptor for Xbox is "game system," i.e.,
        "Xbox(TM) game system." Use the descriptor immediately after mention of
        "Xbox". You should not combine the Xbox trademark with an improper
        generic name or descriptor. For example, game programs designed to run
        on the Xbox game system are not "Xbox games," but rather "games for the
                                    ---
        Xbox system" or "Xbox certified games."

     .    The Xbox trademark may never be abbreviated.  Do not use "X" by
          itself to represent "Xbox."

                                     TO THE
           MICROSOFT CORPORATION XBOX(TM) PUBLISHER LICENSE AGREEMENT

This Supplemental Agreement ("Agreement") is entered into on this 27th day of
March 2001 (the "Effective Date") by and between Microsoft Corporation
("Microsoft") and Interplay Entertainment Corp. ("Licensee") and supplements
that certain Xbox(TM) Publisher License Agreement dated October 12, 2000 (the
"Publisher Agreement").

Microsoft and Licensee hereby supplement the Publisher Agreement as follows:

  1. Definitions; Interpretation.
     ---------------------------

     1.1  Except as expressly provided otherwise in this Supplemental Agreement
("Agreement"), capitalized terms shall have the same meanings ascribed to them
in the Publisher Agreement.

     1.2  "Products" shall mean the following Software Titles, as further
described in Exhibit A-n1, A-n2, A-n3, and A-n4 to the Publisher Agreement
(currently anticipated to be those Software Titles currently known as Giants,
Sacrifice, Hunter and Galleon), or such other substitute Software Titles as the
parties may mutually agree at any time.

     1.3  "Matrix" shall be the Software Title known as the Matrix, and based on
the motion picture known as "The Matrix" (and/or sequels thereto) and as further
described in Exhibit A-n to the Publisher Agreement.

     1.4  If and to the extent that anything contained in this Agreement is
inconsistent with the Publisher Agreement, the terms of this Agreement shall be
deemed to govern.

  2.  Advance. On or before March 27, 2001, Microsoft shall pay Interplay an
      -------
advance payment (the "Advance") in the amount of Five Million Dollars
(US$5,000,000).  Microsoft shall recoup the advance in the manner described
below.

  3.  Recoupment.  Licensee shall make payments ("Recoupment Payments") to
      ----------
Microsoft in the time and manner set forth below in this Section 3.

      3.1  Licensee shall pay Microsoft One Million Dollars ($1,000,000) out of
the proceeds from each of the Products, payable in quarterly increments equal to
Twenty Dollars ($20.00) per Finished Product Unit of the Product sold by
Licensee in the Territory (as such term is defined in the Publisher Agreement)
encompassing the US and Canada (the "NA Territory") during the applicable
Statement Period (as defined below). For the purposes of this Agreement, the
number of Finished Product Units sold shall be calculated as the gross number of
Finished Product Units distributed less the number of Finished Product Units
returned.

      3.2  Licensee shall pay Microsoft $1,000,000 out of the proceeds from
Matrix ("Matrix"), payable in quarterly increments equal to $20.00 per Finished
Product Unit of Matrix sold in the NA Territory during the applicable Statement
Period.  However, if after Licensee pays $1,000,000 out of the proceeds from
Matrix, the aggregate Recoupment Payments received by

                                       1
<PAGE>

Microsoft is less than $5,000,000, Licensee shall continue to pay $20.00 per
Finished Product Unit of Matrix sold by Licensee worldwide calculated
retroactively to the first Finished Product Unit sold until Microsoft shall have
received an amount equal to $5,000,000.

      3.3  If, as of June 30, 2003, Microsoft has not received an aggregate
total of $5,000,000 in Recoupment Payments, Licensee shall pay by July 15, 2003
the difference between $5,000,000 and the Recoupment Payments actually received
by Microsoft as of such date, plus accrued interest at the prime lending rate
plus one percent (1%), calculated as if the $5,000,000 had been due as of the
Effective Date of this Agreement.

      3.4  If any of the following events occur prior to June 30, 2003, Licensee
shall pay the difference between $5,000,000 and the Recoupment Payments then
actually received by Microsoft plus accrued interest at the prime lending rate
plus one percent (1%), calculated as if the $5,000,000 had been due as of the
Effective Date of this Agreement: (a) Licensee ceases development of Matrix at
any time; (b) Matrix fails for any reason to be approved for publication and
distribution pursuant to the Publisher Agreement (provided that Microsoft's
approval or non-approval thereof shall be made in good faith); (c) Licensee
fails to Commercially Release Matrix in the NA Territory within three months
following the commercial theater release of the motion picture tentatively
titled "Matrix 2" or Licensee Commercially Releases Matrix later than the
Playstation 2 version thereof; or (d) if, at any stage in the Matrix development
process (but in no event earlier than June 1, 2002) Microsoft, in its reasonable
judgment, determines that any of the events as described in (a), (b) or (c)
herein is likely to occur. Payment shall be made within fifteen (15) business
days following the date of any such event.

      3.5  If at any time prior to the repayment of the Advance Licensee's
aggregate balance outstanding on (i) its line of credit from La Salle Business
Credit, Inc., (ii) its line of credit from Titus Interactive S.A. ("Titus), and
(iii) repayment of the Advance to Microsoft, exceeds $25,000,000 (the first
"Debt Threshold"), Licensee shall immediately notify Microsoft in writing and
pay Microsoft $1,000,000, within ten (10) business days following the occurrence
of the first Debt Threshold. Licensee shall make additional $1,000,000 payments
at each subsequent Debt Threshold, which shall occur at each $5,000,000
increment above the first Debt Threshold until such time Licensee has paid an
aggregate total of $5,000,000 in Recoupment Payments to Microsoft. All payments
hereunder shall be made within fifteen (15) business days following the date
upon which the payments are due.

      3.6  Interplay agrees that it will at no time prior to Microsoft's
recoupment of the Advance be indebted to Titus for an amount exceeding
$5,000,000, unless Titus' security interest in connection with any debt
exceeding $5,000,000 is subordinate to Microsoft's security interest as further
described in Section 6 and the Security Agreement.

      3.7  If prior to the earlier of (x) June 30, 2003 and (y) the occurrence
of (i) any event described in Section 3.4 above or (ii) an Event of Default
under the Security Agreement (defined herein), Licensee has paid an aggregate
total of Five Million Dollars in Recoupment Payments, Licensee shall have no
obligation to pay Microsoft any additional Recoupment Payments.

      3.8  Payment Process.  Licensee shall deliver to Microsoft true and
           ---------------
accurate statements ("Statements") of Finished Product Units of each Product and
Matrix distributed in each calendar quarter (each quarter, a "Statement Period")

with the payment due for such calendar quarter.  Each Statement shall

                                       2
<PAGE>

be a statement of Licensee's accounts and activities with respect to the
distribution of the Product for the corresponding Statement period, setting
forth information necessary for the calculation of the Recoupment Payments
payable for that Statement period, including, without limitation, Finished
Product Unit prices and units sold, gross receipts and returns. Payment shall be
made by wire transfer, in immediately available funds, to an account and in
accordance with a reasonable procedure, to be specified in writing by Microsoft.
Licensee shall keep all usual and proper records related to its performance
under this Agreement for a minimum period of three (3) years from the date they
are created, and Microsoft shall have the right to audit such records as set
forth in Section 6.4 of the Publisher Agreement. Payments pursuant to this
Agreement shall be in addition to any and all other payment obligations set
forth in the Publisher Agreement. Except as otherwise set forth herein, payments
set forth in this Section 3 shall be in accordance with Sections 6.4 and 6.5 of

Microsoft pursuant to Section 6 of the Publisher Agreement, Licensee shall pay
to Microsoft a supplemental royalty in the amount of $2.00 for each Finished
Product Unit of Matrix distributed by Interplay  in the NA Territory and the

obligation shall only commence, if at all, upon manufacture of the 750,001st
Finished Product Unit, and shall continue until the 1,250,000th Finished Product
Unit is manufactured (i.e., until such time as Microsoft has received a total of
$1,000,000 in supplemental royalties).

     4.2  Payment of the supplemental royalties set forth in this Section 4
shall be in accordance with Sections 6.3, 6.4 and 6.5 of the Publisher

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

     5.1  Product Development.  Licensee shall design and develop Matrix so as
          -------------------
to take advantage of the superior hardware capabilities of Xbox. Attached hereto

for differentiation of the Xbox version of Matrix as compared to other versions
of such game intended for play on game consoles other than Xbox, and the
differentiation implemented by Licensee for Matrix shall be generally consistent
with this Exhibit A, or as otherwise determined by the parties in good faith and
by mutual agreement.

<PAGE>

      5.3  Exclusivity.  Licensee agrees that only Matrix for Xbox, and no other
           -----------
platform version thereof, including without limitation any Playstation 2 version
thereof, shall include any online gameplay capability.  Licensee further agrees

Licensee shall not release in any Territory any interactive entertainment
software product based on or related to Matrix and/or "The Matrix" or "Matrix 2"

platform now known or hereafter developed, unless such product is an add-on or
sequel to Matrix for the Xbox platform and approved pursuant to the terms of the
Publisher Agreement.

      5.4  Nothing in this Agreement shall alter Licensee's responsibility for
performance of its obligations under this Agreement or the Publisher Agreement

intellectual property security agreements related thereto.  The Security
Agreement will contain a clause subordinating the liens granted thereunder to

the same assets of Microsoft's security interest therein.  Licensee agrees to
sign and deliver any documents required by the Security Agreement, which shall
be a condition precedent to the execution of this Agreement.  In order to
accommodate Licensee's other lenders, Microsoft will refrain from filing
financing statements and the Intellectual Property Security Agreements until
April 5, 2001; provided, however, that upon Interplay's written consent,
Microsoft may effect such filings earlier.  ORAL AGREEMENTS OR ORAL COMMITMENTS
TO LOAN MONEY, EXTEND CREDIT, MODIFY LOAN TERMS, OR TO FORBEAR FROM ENFORCING
REPAYMENT OF A DEBT ARE NOT ENFORCEABLE UNDER WASHINGTON LAW.

  7.  Warranty.  In addition to warranties set forth in the Publisher Agreement,
      --------

Products and Matrix to agree to the terms and conditions set forth in this
Agreement, and that it has not previously granted and will not grant any rights
to any third party (including without limitation any sublicenses of any or all
of the Products' and Matrix's distribution rights and/or the right to sublicense
to further third parties) that are inconsistent with such terms.

  8.  Incorporation of Certain Clauses.  Sections 7 and 12 of the Publisher
      --------------------------------
Agreement are incorporated into this Agreement by this reference, mutatis
mutandis.

  9.  Effect on Other Agreements.
      --------------------------

      9.1  Except and to the extent expressly modified by this Agreement,
Publisher Agreement shall remain in full force and effect and are hereby
ratified and confirmed.

      9.2  The breach by Licensee of any of this Agreement or the Publisher
Agreement shall constitute a breach by Licensee of each of this Agreement and
the Publisher Agreement.

     4.8  Attorney-in-Fact.  Debtor hereby irrevocably constitutes and appoints
          ----------------
Secured Party, with full power of substitution, as its true and lawful attorney-

     Instruments for the payment of moneys due under any Collateral and to file
     any claim or to take any other action or proceeding in any court of law or
     equity or otherwise deemed appropriate by Secured Party for the purpose of
     collecting any and all such moneys due under any Collateral whenever

     any court of law or equity or otherwise deemed appropriate by Secured Party
     for the purpose of collecting any and all such moneys due under any
     Collateral whenever payable;

          (b) to pay or discharge charges or liens levied or placed on or
     threatened against the Collateral other than the Permitted Liens, to effect
     any insurance called for by the terms of this Agreement and to pay all or

          (c) to direct any party liable for any payment under any of the
     Collateral to make payment of any and all moneys due, and to become due
     thereunder, directly to Secured Party or as Secured Party shall direct, and
     to receive payment of and receipt for any and all moneys, claims and other

          (d) to sign and indorse any invoices, freight or express bills, bills

     other documents constituting or relating to the Collateral;

          (e) to commence and prosecute any suits, actions or proceedings at law

          (f) to defend any suit, action or proceeding brought against Debtor
     with respect to any Collateral;

          (g) to settle, compromise or adjust any suit, action or proceeding
     described above and, in connection therewith, to give such discharges or
     releases as Secured Party may deem appropriate; and

          (h) generally to sell, transfer, pledge, make any agreement with
     respect to or otherwise deal with any of the Collateral as fully and
     completely as though Secured Party were the absolute owners thereof for all
     purposes, and to do, at Secured Party's option and at Debtor's expense, at
     any time, or from time to time, all acts and things which Secured Party
     reasonably deems necessary to protect, preserve or realize upon the
     Collateral and Secured Party's lien therein, in order to effect the intent
     of this Agreement, all as fully and effectively as Debtor might do.

     Debtor hereby ratifies, to the extent permitted by law, all that such
attorneys lawfully do or cause to be done by virtue hereof.  The power of
attorney granted hereunder is a power coupled with an interest and shall be
irrevocable until the Liabilities are indefeasibly paid in full.

                                       9
<PAGE>

     Debtor also authorizes Secured Party, at any time from and after the
occurrence and during the continuation of any Event of Default, (x) to
communicate in its own name with any party to any Contract with regard to the
assignment of the right, title and interest of Debtor in and under the Contracts
hereunder and other matters relating thereto and (y) to execute, in connection
with any sale of Collateral provided for in Section 4.5 hereof, any
endorsements, assignments or other instruments of conveyance or transfer with
respect to the Collateral.

     4.9   Perfection.  No earlier than April 5, 2001, Debtor shall file such
           ----------
financing statements, assignments for security and other documents in such
offices as may be necessary or as Secured Party or the Representative may
request to perfect the security interests granted by Section 3 of this
Agreement.  Debtor hereby authorizes Secured Party to file a financing statement
describing the Collateral

     4.10  Termination.  This Agreement and the liens and security interests
           -----------
granted hereunder shall not terminate until the complete performance and
indefeasible satisfaction of all the Liabilities, whereupon Secured Party shall
forthwith cause to be assigned, transferred and delivered, against receipt but
without any recourse, warranty or representation whatsoever, any remaining
Collateral to or on the order of Debtor.

     4.11  Further Assurances.  At any time and from time to time, upon the
           ------------------
written request of Secured Party or its Representative, and at the sole expense
of Debtor, Debtor will promptly and duly execute and deliver any and all such
further instruments, documents and agreements and take such further actions as
Secured Party or its Representative may reasonably require in order for Secured
Party to obtain the full benefits of this Agreement and of the rights and powers
herein granted in favor of Secured Party.

     4.12  Limitation on Duty of Secured Party.  The powers conferred on Secured
           -----------------------------------
Party under this Agreement are solely to protect Secured Party's interest in the
Collateral and shall not impose any duty upon it to exercise any such powers.
Secured Party shall be accountable only for amounts that it actually receives as
a result of the exercise of such powers and neither Secured Party nor its
Representative nor any of their respective officers, directors, employees or
agents shall be responsible to Debtor for any act or failure to act, except for
willful misconduct.  Without limiting the foregoing, Secured Party and any
Representative shall be deemed to have exercised reasonable care in the custody
and preservation of the Collateral in their possession if such Collateral is
accorded treatment substantially equivalent to that which the relevant Secured
Party or any Representative, in its individual capacity, accords its own
property consisting of the type of Collateral involved, it being understood and
agreed that neither Secured Party nor any Representative shall have any
responsibility for taking any necessary steps (other than steps taken in
accordance with the standard of care set forth above) to preserve rights against
any person with respect to any Collateral.

     Also without limiting the generality of the foregoing, neither Secured
Party nor any Representative shall have any obligation or liability under any
Contract or license by reason of or arising out of this Agreement or the
granting to Secured Party of a security interest therein or assignment thereof
or the receipt by Secured Party or any Representative of any payment relating to
any Contract or license pursuant hereto, nor shall Secured Party or any
Representative be required or obligated in any manner to perform or fulfill any
of the obligations of Debtor under or pursuant to any Contract or license, or to
make any payment, or to make any inquiry as to the nature or the sufficiency of
any payment received by it or the sufficiency of any performance by any party
under any Contract or license, or to present or file any claim, or to take any
action to collect or enforce any performance or the payment of any amounts which
may have been assigned to it or to which it may be entitled at any time or
times.

                              CONSULTING AGREEMENT

This CONSULTING AGREEMENT (this "Agreement") made as of this 12th day of April,
2001 is by and between Intraco Systems, Inc., a Nevada corporation, with its
principal place of business at 3998 FAU Blvd, Suite 210 Suite 300, Boca Raton,
FL 33431 (the "Company"), and Titlest Investments and Keva Martin, Principal,
with its principal place of business at 2901 Clint Moore Road, #339, Boca Raton,
FL (the "Consultant").

                                R E C I T A L S:

The Company is a public company whose stock is publicly traded on the NASDAQ BB,
and desires to retain Consultant.

Consultant is in the business of providing consulting services and desires to
provide certain additional consulting services to the Company in accordance with
the terms and conditions contained hereinafter.

The Company desires to pay consultant for such services and through the issuance
of common stock as compensation.

NOW, THEREFORE, the parties hereto hereby agree as follows:

         CONSULTING SERVICES. The Consultant is hereby retained by the Company
to provide consulting services to the Company, as said services relate to
corporate finance matters, including advice regarding acquisitions, mergers and
joint ventures. Consultant shall provide such consulting services as reasonably
requested by the Company during the term of this Agreement, provided that
nothing hereunder shall require Consultant to devote a minimum number of hours
per calendar month toward the performance of services. The level of services
that may reasonably be requested hereunder shall be dependent, in part, on the
amount of compensation to be paid Consultant by the Company hereunder. Unless
otherwise agreed to by Consultant, all services hereunder shall be performed by
Consultant, in its sole discretion, at its place of business or other offices.
Notwithstanding anything contained herein to the contrary, the services to be
performed by Consultant hereunder may be performed by any employee or consultant
to Consultant.

         COMPENSATION. In consideration for the performance of services
hereunder, the Company hereby agrees to pay Consultant the aggregate sum of
1,500,000 shares of the Company's common stock as full compensation for the term
of this Agreement, based on the current stock price of approximately $.05 per
share, as follows: (a) 500,000 shares shall be issued for services rendered and
to be rendered in fiscal 2001, (b) 500,000 shares shall be issued for services
to be rendered in fiscal 2002, and (c) 500,000 shares shall be issued for
introduction of potential customers and acquisitions. The Consultant is
responsible for all of his incidental out of pocket expenses. The Company hereby
agrees to pay on a pre-approval basis extraordinary expenses incurred by
Consultant in connection with such services to be rendered hereunder. Consultant
may, from time to time, deem it to be in the best interests of the Company to
retain an outside consultant in connection with certain specific acquisitions or
proposed transactions. In such event, the Company hereby agrees to pay any and
all fees and expenses of such consultant. In addition, Titlest shall receive
500,000 cashless options at a price of $.10.

         TERM. The term of this Agreement shall be for one year commencing as of
the date first written above and terminating one day prior to the first
anniversary hereof; provided, however, that this Agreement shall be renewable
for subsequent one year terms, by mutual agreement of the parties in writing, at
least thirty (30) days prior to the expiration of the then current term.
<PAGE>

         INDEMNIFICATION. The Company hereby agrees to indemnify, defend and
hold harmless Consultant, its officers, directors, principals, employees,
affiliates, and shareholders, and their successors and assigns from and against
any and all claims, damages, losses, liability, deficiencies, actions, suits,
proceedings, costs or legal expenses (collectively the "Losses") arising out of
or resulting from: (i) any breach of a representation, or warranty by the
Company contained in this Agreement; or (ii) any activities or services
performed hereunder by Consultant, unless such Losses were the result of the
intentional misconduct or gross misconduct of Consultant; or (iii) any and all
costs and expenses (including reasonable attorneys' and paralegals' fees)
related to the foregoing, and as more fully described below.

         REPRESENTATIONS OF THE COMPANY. The Company hereby represents and
warrants that any and all information supplied hereunder to Consultant in
connection with any and all services to be performed hereunder by Consultant for
and on behalf of the Company shall be true, complete and correct as of the date
of such dissemination and shall not fail to state a material fact necessary to
make any of such information not misleading. The Company hereby acknowledges
that the ability of Consultant to adequately provide accounting and acquisition
related consulting services hereunder and/or to initiate and/or effectuate
introductions on behalf of the Company with respect to potential acquisitions is
dependent upon the prompt dissemination of accurate, correct and complete
information to Consultant. In addition, and notwithstanding anything contained
herein to the contrary, nothing hereunder shall obligate Consultant to make any
minimum number of introductions hereunder or to initiate any merger or
acquisitions involving or relating to the Company. The Company further
represents and warrants hereunder that this Agreement and the transactions
contemplated hereunder, have been duly and validly authorized by all requisite
corporate action; that the Company has the full right, power and capacity to
execute, deliver and perform its obligations hereunder; and that this Agreement,
upon execution and delivery of the same by the Company, will represent the valid
and binding obligation of the Company enforceable in accordance with its terms.
The representations and warranties set forth herein shall survive the
termination of this Agreement.

         NOTICES. All notices, demands or other communications given hereunder
shall be in writing and shall be deemed to have been duly given when delivered
in person or transmitted by facsimile transmission or the third calendar day
after being mailed by United States registered or certified mail, return receipt
requested, postage prepaid, to the addresses herein above first mentioned or to
such other address as any party hereto shall designate to the other for such
purpose in the manner hereinafter set forth.

         ENTIRE AGREEMENT. This Agreement contains all of the understandings and
agreements of the parties with respect to the subject matter discussed herein.
All prior agreements, whether written or oral, are merged herein and shall be of
no force or effect.

         AMENDMENT. No modification, waiver, amendment, discharge or change of
this Agreement shall be valid unless the same is evidenced by a written
instrument, executed by the party against which such modification, waiver,
amendment, discharge, or change is sought.

         SEVERABILITY. The invalidity, illegality or unenforceability of any
provision or provisions of this Agreement will not affect any other provision of
this Agreement, which will remain in full force and effect, nor will the
invalidity, illegality or unenforceability of a portion of any provision of this
Agreement affect the balance of such provision. In the event that any one or
more of the provisions contained in this Agreement or any portion thereof shall
for any reason be held to be invalid, illegal or unenforceable in any respect,
this Agreement shall be reformed, construed and enforced as if such invalid,
illegal or unenforceable provision had never been contained herein.
<PAGE>

         CONSTRUCTION AND ENFORCEMENT. This Agreement shall be construed and
interpreted in accordance with the laws of the state of Florida. The parties
hereto agree that any dispute arising under this Agreement, whether during the
Term of at any subsequent time, shall be resolved exclusively through
arbitration in the state of Florida.

         BINDING NATURE. The terms and provisions of this Agreement shall be
binding upon and inure to the benefit of the parties, and their respective
successors and assigns.

         COUNTERPARTS. This Agreement may be executed in any number of
counterparts, including facsimile signatures which shall be deemed as original
signatures. All executed counterparts shall constitute one Agreement,
notwithstanding that all signatories are not signatories to the original or the
same counterpart.

IN WITNESS  WHEREOF,  the parties  hereto have executed this Agreement as of the
date first above written.
