                                  RISK FACTORS

     You should carefully consider the risks described below before investing in
our common stock. The occurrence of any of the following risks could harm our
business and our prospects. In that event, our business may be negatively
affected, the price of our stock may decline and you may lose part or all of
your investment.

We depend on a relatively small number of brands for a significant portion of
our revenues and profits.

     A significant portion of our revenues are derived from products based on a
relatively small number of popular brands each year. In addition, many of these
products have substantial production or acquisition costs and marketing budgets.
In our fiscal year ended March 31, 2001, 49% of our worldwide net publishing
revenues (37% of consolidated net revenues) was derived from two brands, one of
which accounted for 39% and the other of which accounted for 10% of worldwide
net publishing revenues (29% and 8%, respectively, of consolidated net
revenues). In our fiscal year ended March 31, 2000, two brands accounted for 34%
of our worldwide net publishing revenues (24% of consolidated net revenues), one
of which accounted for 19%, and the other of which accounted for 15% of
worldwide net publishing revenues (13% and 11%, respectively, of consolidated
net revenues). We expect that a limited number of popular brands will continue
to produce a disproportionately large amount of our revenues. Due to this
dependence on a limited number of brands, the failure of one or more products
based on these brands to achieve anticipated results may significantly harm our
business and financial results.

Our future success depends on our ability to release popular products.

     The life of any one game product is relatively short, in many cases less
than one year. It is therefore important for us to be able to continue to
develop many high quality new products that are popularly received. If we are
unable to do this, our business and financial results may be significantly

     We focus our development and publishing activities principally on products
that are, or have the potential to become, franchise brand properties. Many of
these products are based on intellectual property and other character or story
rights acquired or licensed from third parties. The license and distribution
agreements are limited in scope and time, and we may not be able to renew key
licenses when they expire or to include new products in existing licenses. The
loss of a significant number of our intellectual property licenses or of our
relationships with licensors could have a material adverse effect on our ability
to develop new products and therefore on our business and financial results.

The current transition in console platforms has a material impact on the market
for interactive entertainment software.

     When new console platforms are announced or introduced into the market,
consumers typically reduce their purchases of game console entertainment
software products for current console platforms in anticipation of new platforms
becoming available. During these periods, sales of our game console
entertainment software products can be expected to slow down or even decline
until new platforms have been introduced and have achieved wide consumer
acceptance. We are currently experiencing such a transition period. Each of the
three current principal hardware producers has either launched or announced that
it will launch a new platform in the near future. Sony made the first shipments
of its PlayStation 2 console system in North America and Europe in the fourth
quarter of calendar year 2000. During that quarter, Sony's manufacturing
shortages resulted in significant shipment delays of PlayStation 2 units in
North America and Europe. Nintendo announced that its new console system,
Nintendo GameCube, will be released in the fourth quarter of calendar year 2001
in Japan and North America and in calendar year 2002 in Europe. Microsoft
announced that its new console system, Xbox, will be released in the fourth
quarter of calendar year 2001 in North America and Japan and in calendar year
2002 in Europe. In June 2001, Nintendo launched its Game Boy Advance hand held
device. Delays in the launch, shortages of these platforms or lack of consumer
acceptance could adversely affect our sales of


products for these platforms. Current sales of our products for the existing
PlayStation and Nintendo 64 platforms have been negatively affected by the new
platform transition.

We must make significant expenditures to develop products for new platforms
which may not be successful or released when anticipated.

     The interactive entertainment software industry is subject to rapid
technological change. New technologies could render our current products or
products in development obsolete or unmarketable. We must continually anticipate
and assess the emergence and market acceptance of new interactive entertainment
software platforms well in advance of the time the platform is introduced to
consumers. New platforms have historically required the development of new
software and also have the effect of undermining demand for products based on
older technologies. Because product development cycles are difficult to predict,
we must make substantial product development and other investments in a
particular platform well in advance of introduction of the platform. If the
platforms for which we develop new software products or modify existing products
are not released on a timely basis or do not attain significant market
penetration, or if we develop products for a delayed or unsuccessful platform,
we may not be able to recover in revenues our development costs which could be
significant and our business and financial results could be significantly
harmed. A recent announcement by Sega Corporation that it has discontinued its
Dreamcast platform shows that even experienced hardware manufacturers are not
immune to failure.

We are exposed to seasonality in the purchases of our products.

     The interactive entertainment software industry is highly seasonal, with
the highest levels of consumer demand occurring during the year-end holiday
buying season. As a result, our net revenues, gross profits and operating income
have historically been highest during the second half of the year. Additionally,
in a platform transition period such as the one taking place now, sales of game
console software products can be significantly affected by the timeliness of
introduction of game console platforms by the manufacturers of those platforms,
such as Sony, Microsoft and Nintendo. The timing of hardware platform
introduction is also often tied to holidays and is not within our control.
Further, delays in development, licensor approvals or manufacturing can also
affect the timing of the release of our products, causing us to miss key selling
periods such as the year-end holiday buying season.

We depend on skilled personnel.

     Our success depends to a significant extent on our ability to identify,
hire and retain skilled personnel. The software industry is characterized by a
high level of employee mobility and aggressive recruiting among competitors for
personnel with technical, marketing, sales, product development and management
skills. We may not be able to attract and retain skilled personnel or may incur
significant costs in order to do so. If we are unable to attract additional
qualified employees or retain the services of key personnel, our business and
financial results could be negatively impacted.

We depend on Sony and Nintendo for the manufacture of products that we develop
for their hardware platforms.

     Generally, when we develop interactive entertainment software products for
hardware platforms offered by Sony or Nintendo, the products are manufactured
exclusively by that hardware manufacturer. Our hardware platform licenses with
Sony and Nintendo provide that the manufacturer may change prices for the
manufacturing of products. In addition, these agreements include other
provisions such as approval rights of all products and related promotional
materials that give the manufacturer substantial control over our costs and the
release of new titles. Since each of the manufacturers is also a publisher of
games for its own hardware platforms and manufactures products for all of its
other licensees, a manufacturer may give priority to its own products or those
of our competitors in the event of insufficient manufacturing capacity. Our
business and


financial results could be materially harmed by unanticipated delays in the
manufacturing and delivery of our products by Sony or Nintendo. In addition, our
business and financial results could be materially harmed if Sony or Nintendo
used their rights under these agreements to delay the manufacture or delivery of
our products, limit the costs recoverable by us to manufacture software for
their consoles, or elect to manufacture software themselves or use developers
other than us.

If our products contain defects, our business could be harmed significantly.

     Software products as complex as the ones we publish may contain undetected
errors when first introduced or when new versions are released. We cannot assure
you that, despite extensive testing prior to release, errors will not be found
in new products or releases after shipment, resulting in loss of or delay in
market acceptance. This loss or delay could significantly harm our business and
financial results.

Inadequate intellectual property protections could prevent us from enforcing or
defending our proprietary technology.

     We regard our software as proprietary and rely on a combination of
copyright, trademark and trade secret laws, employee and third party
nondisclosure agreements and other methods to protect our proprietary rights. We
own or license various copyrights and trademarks. While we provide "shrinkwrap"
license agreements or limitations on use with our software, it is uncertain to
what extent these agreements and limitations are enforceable. We are aware that
some unauthorized copying occurs within the computer software industry, and if a
significantly greater amount of unauthorized copying of our interactive
entertainment software products were to occur, it could cause material harm to
our business and financial results.

     Policing unauthorized use of our products is difficult, and software piracy
can be a persistent problem, especially in some international markets. Further,
the laws of some countries where our products are or may be distributed either
do not protect our products and intellectual property rights to the same extent
as the laws of the United States, or are poorly enforced. Legal protection of
our rights may be ineffective in such countries, and as we leverage our software
products using emerging technologies such as the Internet and online services,
our ability to protect our intellectual property rights and to avoid infringing
intellectual property rights of others may diminish. We cannot assure you that
existing intellectual property laws will provide adequate protection for our
products in connection with these emerging technologies.

We may be subject to intellectual property claims.

     As the number of interactive entertainment software products increases and
the features and content of these products continue to overlap, software
developers increasingly may become subject to infringement claims. Many of our
products are highly realistic and feature materials that are based on real world
examples, which may inadvertently infringe upon the intellectual property rights
of others. Although we believe that we make reasonable efforts to ensure that
our products do not violate the intellectual property rights of others, it is
possible that third parties still may claim infringement. From time to time, we
receive communications from third parties regarding such claims. Existing or
future infringement claims against us, whether valid or not, may be time
consuming and expensive to defend.

     Intellectual property litigation or claims could force us to do one or more
of the following:

     o    Cease selling, incorporating or using products or services that
          incorporate the challenged intellectual property;

     o    Obtain a license from the holder of the infringed intellectual
          property, which if available at all, may not be available on
          commercially favorable terms; or


     o    Redesign our interactive entertainment software products, which
          could cause us to incur additional costs, delay introduction and
          possibly reduce commercial appeal of our products.

     Any of these actions may cause material harm to our business and financial

We rely on independent third parties to develop many of our software products.

     We often rely on independent third party interactive entertainment software
developers to develop many of our software products. Since we depend on these
developers in the aggregate, we remain subject to the following risks:

     o    Continuing strong demand for developers' resources, combined with
          recognition they receive in connection with their work, may cause
          developers who worked for us in the past to either work for our
          competitors in the future or to renegotiate our agreements with them
          on terms less favorable to us.

     o    Limited financial resources and business expertise and inability to
          retain skilled personnel may force developers out of business prior to
          completing our products or require us to fund additional costs.

     Increased competition for skilled third party software developers also has
compelled us to agree to make significant advance payments on royalties to game
developers. If the products subject to these arrangements do not generate
sufficient revenues to recover these royalty advances, we would have to
write-off unrecovered portions of these payments, which could cause material
harm to our business and financial results. In a few cases, we also agree to pay
developers fixed per unit product royalties after royalty advances are fully
recouped. To the extent that sales prices of products on which we have agreed to
pay a fixed per unit royalty are marked down, our profitability could be
adversely affected.

We operate in a highly competitive industry.

     The interactive entertainment software industry is intensely competitive
and new interactive entertainment software products and platforms are regularly
introduced. Our competitors vary in size from small companies to very large
corporations with significantly greater financial, marketing and product
development resources than we have. Due to these greater resources, certain of
our competitors can undertake more extensive marketing campaigns, adopt more
aggressive pricing policies, pay higher fees to licensors of desirable motion
picture, television, sports and character properties and pay more to third party
software developers than we can. We believe that the main competitive factors in
the interactive entertainment software industry include: product features; brand
name recognition; compatibility of products with popular platforms; access to
distribution channels; quality of products; ease of use; price; marketing
support; and quality of customer service.

     We compete primarily with other publishers of personal computer and video
game console interactive entertainment software. Significant third party
software competitors currently include, among others: Acclaim Entertainment,
Inc.; Capcom Co. Ltd.; Eidos PLC; Electronic Arts Inc.; Infogrames SA; Konami
Company Ltd.; Namco Ltd.; Take-Two Interactive Software, Inc.; THQ Inc. and
Vivendi Universal Publishing. In addition, integrated video game console
hardware and software companies such as Sony Computer Entertainment, Nintendo
Co. Ltd., Microsoft Corporation and Sega Enterprises, Ltd. compete directly with
us in the development of software titles for their respective platforms. In
addition, Sega produces software titles for other platforms.


     We also compete with other forms of entertainment and leisure activities.
For example, we believe that the overall growth in the use of the Internet and
online services by consumers may pose a competitive threat if customers and
potential customers spend less of their available time using interactive
entertainment software and more using the Internet and online services.

We may face difficulty obtaining access to retail shelf space necessary to
market and sell our products effectively.

     Retailers of our products typically have a limited amount of shelf space
and promotional resources, and there is intense competition among consumer
interactive entertainment software products for high quality retail shelf space
and promotional support from retailers. To the extent that the number of
products and platforms increases, competition for shelf space may intensify and
may require us to increase our marketing expenditures. Retailers with limited
shelf space typically devote the most and highest quality shelf space to the
best selling products. We cannot assure you that our new products will
consistently achieve such "best seller" status. Due to increased competition for
limited shelf space, retailers and distributors are in an increasingly better
position to negotiate favorable terms of sale, including price discounts, price
protection, marketing and display fees and product return policies. Our products
constitute a relatively small percentage of any retailer's sale volume, and we
cannot assure you that retailers will continue to purchase our products or to
provide our products with adequate levels of shelf space and promotional support
on acceptable terms. A prolonged failure in this regard may significantly harm
our business and financial results.

Our sales may decline substantially without warning and in a brief period of
time because we generally do not have long-term contracts for the sale of our

     We currently sell our products directly through our own sales force to mass
merchants, warehouse club stores, large computer and software specialty chains
and through catalogs, as well as to a limited number of distributors, in the
United States and Canada. Outside North America, we sell our products directly
to retailers as well as third party distributors in certain territories. Our
sales are made primarily on a purchase order basis without long-term agreements
or other forms of commitments. The loss of, or significant reduction in sales
to, any of our principal retail customers or distributors could significantly
harm our business and financial results. Our two largest customers, Wal-Mart
Stores, Inc. and Toys "R" Us, Inc., accounted for approximately 13% and 12%,
respectively, of our worldwide net publishing revenues for our fiscal year ended
March 31, 2001 (10% and 9%, respectively, of our consolidated net revenues). Our
five largest retailers, including Wal-Mart and Toys "R" Us, accounted for
approximately 45% of our worldwide net publishing revenues for our fiscal year
ended March 31, 2001 (34% of our consolidated net revenues). Our two largest
customers, Wal-Mart and Toys "R" Us, accounted for approximately 13% and 9%,
respectively, of our worldwide net publishing revenues for our fiscal year ended
March 31, 2000 (9% and 6%, respectively, of our consolidated net revenues). Our
five largest retailers, including Wal-Mart and Toys "R" Us, accounted for
approximately 37% of our worldwide net publishing revenues for our fiscal year
ended March 31, 2000 (26% of our consolidated net revenues).

Our customers have the right to return our products and to receive pricing
concessions and such rights could reduce our net revenues and results of

     We are exposed to the risk of product returns and price protection with
respect to our distributors and retailers. Return policies allow distributors
and retailers to return defective, shelf-worn and damaged products in accordance
with negotiated terms. Price protection policies, when negotiated and
applicable, allow customers a credit against amounts they owe us with respect to
merchandise unsold by them. We provide price protection to a number of our
customers to manage our customers' inventory levels in the distribution channel.
We also offer a 90-day limited warranty to our end users that our products will
be free from manufacturing defects. Although we maintain a reserve for returns
and price protection, and although our agreements with a number of our customers
place limits on product returns and price protection, we could be forced to


substantial product returns and provide price protection to maintain our
relationships with retailers and our access to distribution channels. Product
returns and price protection that exceed our reserves could significantly harm
our business and financial results.

We may be burdened with payment defaults and uncollectible accounts if our
distributors or retailers cannot honor their credit arrangements with us.

     Distributors and retailers in the interactive entertainment software
industry have from time to time experienced significant fluctuations in their
businesses, and a number of them have failed. The insolvency or business failure
of any significant retailer or distributor of our products could materially harm
our business and financial results. We typically make sales to most of our
retailers and some distributors on unsecured credit, with terms that vary
depending upon the customer and the nature of the product. Although we have
insolvency risk insurance to protect against our customers' bankruptcy,
insolvency or liquidation, this insurance contains a significant deductible and
a co-payment obligation, and the policy does not cover all instances of
non-payment. In addition, while we maintain a reserve for uncollectible
receivables, the reserve may not be sufficient in every circumstance. As a
result, a payment default by a significant customer could significantly harm our
business and financial results.

We may not be able to maintain our distribution relationships with key vendors.

     Our CD Contact, NBG and CentreSoft subsidiaries distribute interactive
entertainment software products and provide related services in the Benelux
territories, Germany and the United Kingdom, respectively, and, via export, in
other European territories for a variety of entertainment software publishers,
many of which are our competitors. These services are generally performed under
limited term contracts. While we expect to use reasonable efforts to retain
these vendors, we may not be successful in this regard. The cancellation or
non-renewal of one or more of these contracts could significantly harm our
business and financial results. Sony and Eidos products accounted for
approximately 26% and 13%, respectively, of our worldwide net distribution
revenues for our fiscal year ended March 31, 2001.

Our international revenues may be subject to regulatory requirements as well as
currency fluctuations.

     Our international revenues have accounted for a significant portion of our
total revenues. International sales and licensing accounted for 66%, 51% and 43%
of our total net revenues in our fiscal years ended March 31, 1999, March 31,
2000 and March 31, 2001, respectively. We expect that international revenues
will continue to account for a significant portion of our total revenues in the
future. International sales may be subject to unexpected regulatory
requirements, tariffs and other barriers. Additionally, foreign sales which are
made in local currencies may fluctuate. Presently, we do not engage in currency
hedging activities. Although exposure to currency fluctuations to date has been
insignificant, fluctuations in currency exchange rates may in the future have a
material negative impact on revenues from international sales and licensing and
thus our business and financial results.

Our software may be subject to governmental restrictions or rating systems.

     Legislation is periodically introduced at the local, state and federal
levels in the United States and in foreign countries to establish a system for
providing consumers with information about graphic violence and sexually
explicit material contained in interactive entertainment software products. In
addition, many foreign countries have laws that permit governmental entities to
censor the content and advertising of interactive entertainment software. We
believe that mandatory government-run rating systems eventually may be adopted
in many countries that are significant markets or potential markets for our
products. We may be required to modify our products or alter our marketing
strategies to comply with new regulations, which could delay the release of our
products in those countries.


     Due to the uncertainties regarding such rating systems, confusion in the
marketplace may occur, and we are unable to predict what effect, if any, such
rating systems would have on our business. In addition to such regulations,
certain retailers have in the past declined to stock some of our products
because they believed that the content of the packaging artwork or the products
would be offensive to the retailer's customer base. While to date these actions
have not caused material harm to our business, we cannot assure you that similar
actions by our distributors or retailers in the future would not cause material
harm to our business.

Our software may be subject to legal claims.

     Within the past two years, two lawsuits, Linda Sanders, et al. v. Meow
Media, Inc., et al., United States District Court for the District of Colorado,
and Joe James, et al. v. Meow Media, Inc., et al., United States District Court
for the Western District of Kentucky, Paducah Division, have been filed against
numerous video game companies, including us, by the families of victims who were
shot and killed by teenage gunmen. These lawsuits allege that the video game
companies manufactured and/or supplied these teenagers with violent video games,
teaching them how to use a gun and causing them to act out in a violent manner.
While our general liability insurance carrier has agreed to defend us in these
lawsuits, it is uncertain whether or not the insurance carrier would cover all
or any amounts which we might be liable for if the lawsuits are not decided in
our favor. If either of the lawsuits are decided against us and our insurance
carrier does not cover the amounts we are liable for, it could have a material
adverse effect on our business and financial results. It is possible that
similar additional lawsuits may be filed in the future. Payment of significant
claims by insurance carriers may make such insurance coverage materially more
expensive or unavailable in the future, thereby exposing our business to
additional risk.

We may face limitations on our ability to integrate additional acquired
businesses or to find suitable acquisition opportunities.

     We intend to pursue additional acquisitions of companies, properties and
other assets that can be purchased or licensed on acceptable terms and which we
believe can be operated or exploited profitably. Some of these transactions
could be material in size and scope. While we will continually be searching for
additional acquisition opportunities, we may not be successful in identifying
suitable acquisitions. As the interactive entertainment software industry
continues to consolidate, we face significant competition in seeking and
consummating acquisition opportunities. We may not be able to consummate
potential acquisitions or an acquisition may not enhance our business or may
decrease rather than increase our earnings. In the future, we may issue
additional shares of our common stock in connection with one or more
acquisitions, which may dilute our existing stockholders. Future acquisitions
could also divert substantial management time and result in short term
reductions in earnings or special transaction or other charges. In addition, we
cannot guarantee that we will be able to successfully integrate the businesses
that we may acquire into our existing business. Our stockholders may not have
the opportunity to review, vote on or evaluate future acquisitions.

Our shareholder rights plan, charter documents and other agreements may make it
more difficult to acquire us without the approval of our Board of Directors.

     We have adopted a shareholder rights plan under which one right entitling
the holder to purchase one one-hundredth of a share of our Series A Junior
Preferred Stock at a price of $40 per share (subject to adjustment) is attached
to each outstanding share of common stock. Such shareholder rights plan makes an
acquisition of control in a transaction not approved by our Board of Directors
more difficult. Our Amended and Restated By-laws have advance notice provisions
for nominations for election of nominees to the Board of Directors which may
make it more difficult to acquire control of us. Our long-term incentive plans
provide for acceleration of stock options following a change in control, which
has the effect of making an acquisition of control more expensive. A change in
control constitutes a default under our revolving credit facility. In addition,
some of our officers have severance compensation agreements that provide for
substantial cash payments and acceleration of other benefits in the event of
change in control. These agreements and


arrangements may also inhibit a change
in control and may have a negative effect on the market price of our common

Our stock price is highly volatile.

     The trading price of our common stock has been and could continue to be
subject to wide fluctuations in response to certain factors, including:

          o    Quarter to quarter variations in results of operations

          o    Our announcements of new products

          o    Our competitors' announcements of new products

          o    Our product development or release schedule

          o    General conditions in the computer, software, entertainment,
               media or electronics industries

          o    Timing of the introduction of new platforms and delays in the
               actual release of new platforms

          o    Changes in earnings estimates or buy/sell recommendations by

          o    Investor perceptions and expectations regarding our products,
               plans and strategic position and those of our competitors and

Other events or factors.

     In addition, the public stock markets experience extreme price and trading
volume volatility, particularly in high technology sectors of the market. This
volatility has significantly affected the market prices of securities of many
technology companies for reasons often unrelated to the operating performance of
the specific companies. These broad market fluctuations may adversely affect the
market price of our common stock.

We do not pay dividends on our common stock.

     We have not paid any dividends on our common stock and do not anticipate
paying dividends in the near future. In addition, our revolving credit facility
currently prohibits us from paying dividends on our common stock.

and Nintendo GameCube console systems, which are expected to launch in North
America and Japan later this year and in Europe next year. At present we have
153 different titles in various stages of production, development and planning,
80 of which are in production and development and 73 of which are in various
planning stages. Driven partly by the enhanced capabilities of the next
generation of platforms, we believe that in the next few years there will be
significant growth in the market for interactive entertainment software and we
plan to leverage our skills and resources to extend our leading position in the

     Our publishing business involves the development, marketing and sale of
products, either directly, by license or through our affiliate label program
with third party publishers. In addition to publishing, we maintain distribution
operations in Europe that provide logistical and sales services to third party
publishers of interactive entertainment software, our own publishing operations
and manufacturers of interactive entertainment hardware.

     Our objective is to be a worldwide leader in the development, publishing
and distribution of quality interactive entertainment software products that
deliver a highly satisfying consumer entertainment experience. Our strategy
includes the following elements:

     Create and Maintain Diversity in Product Mix, Platforms and Markets. We
believe that maintaining a diversified mix of products can reduce our operating
risks and enhance profitability. Therefore, we develop and publish products
spanning a wide range of product categories, including action, adventure,
extreme sports, racing, role playing, simulation and strategy, and products
designed for target audiences ranging from game enthusiasts and children to mass
market consumers and "value priced" buyers. We develop, publish and distribute
products that operate on Sony PlayStation and PlayStation 2, Sega Dreamcast and
Nintendo 64 console systems, Nintendo Game Boy hand held devices and the
personal computer. In anticipation of the launch of Microsoft's Xbox and
Nintendo's GameCube and in response to the previous launch of other next
generation platforms, we currently have 57 titles under development for next
generation platforms. We typically release our console products for use on
multiple platforms in order to reduce the risks associated with any single
platform, leverage our costs over a larger installed base and increase unit

     Create, Acquire and Maintain Strong Brands. We focus development and
publishing activities principally on products that are, or have the potential to
become, franchise properties with sustainable consumer appeal and brand
recognition. These products can thereby serve as the basis for sequels, prequels
and related new products that can be released over an extended period of time.
We believe that the publishing and distribution of products based in large part
on franchise properties enhances predictability of revenues and the probability
of high unit volume sales and operating profits. We have entered into a series
of strategic relationships with the owners of intellectual property pursuant to
which we have acquired the rights to publish products based on franchises such
as Star Trek, various Disney films such as Toy Story 2 and Marvel Comics'
properties such as Spider?Man, X-Men and Blade. We have also capitalized on the
success of our Tony Hawk's Pro Skater products to sign long term agreements,
many of which are exclusive, with numerous other


extreme sports athletes including superstars Mat Hoffman in BMX pro biking,
Kelly Slater in pro surfing, Shaun Palmer in snowboarding and Shaun Murray in

     Enforce Disciplined Product Selection and Development Processes. The
success of our publishing business depends, in significant part, on our ability
to develop games that will generate high unit volume sales and that can be
completed up to our high quality standards. Our publishing units have
implemented a formal control process for the selection, development, production
and quality assurance of our products. We apply this process, which we refer to
as the "Greenlight Process," to products under development with external, as
well as internal resources. The Greenlight Process includes in-depth reviews of
each project at five intervals during the development process by a team that
includes several of our highest ranking operating managers and coordination
between our sales and marketing personnel and development staff at each step in
the process.

     We develop our products using a strategic combination of our internal
development resources and external development resources acting under contract
with us, some of whom are independent and some of whom are partly owned or
otherwise controlled by us. We typically select our external developers based on
their track record and expertise in producing products in the same category. One
developer will often produce the same game for multiple platforms and will
produce sequels to the original game. We believe that this selection process
allows us to strengthen and leverage the particular expertise of our internal
and external development resources.

     Continue to Improve Profitability. We are continually striving to reduce
our risk and increase our operating leverage and efficiency with the goal of
increased profitability. We believe the key factor affecting our profitability
will be the success rate of our product releases. Therefore, our product
selection and development process includes, as a significant component, periodic
evaluations of the expected commercial success of products under development.
Through this process, titles that we determine to be less promising are either
discontinued before we incur additional development costs, or if necessary,
corrections can be made in the development process. In addition, our focus on
cross platform releases and branded products will, we believe, contribute to
this strategic goal.

     In order to further our emphasis on improved profitability, we have
implemented a number of operational initiatives. We have significantly increased
our product development capabilities by allocating a larger portion of our
product development investments to experienced independent development companies
working under contract with us, thereby taking advantage of specialized third
party developers without incurring the fixed overhead obligations associated
with increased internally employed staff. Our sales and marketing operations
work with our studio resources to increase the visibility of new product
launches and to coordinate timing and promotion of product releases. Our finance
and administration and sales and marketing personnel work together to improve
inventory management and receivables collections. We have broadly instituted
objective-based reward programs that provide incentives to management and staff
throughout the organization to produce results that meet our financial

     Grow Through Continued Strategic Acquisitions and Alliances. The
interactive entertainment industry is consolidating, and we believe that success
in this industry will be driven in part by the ability to take advantage of
scale. Specifically, smaller companies are more capital constrained, enjoy less
predictability of revenues and cash flow, lack product diversity and must spread
fixed costs over a smaller revenue base. Several industry leaders are emerging
that combine the entrepreneurial and creative spirit of the industry with
professional management, the ability to access the capital markets and the
ability to maintain favorable relationships with strategic developers, property
owners and retailers. Through ten completed acquisitions since 1997, we believe
that we have successfully diversified our operations, our channels of
distribution, our development talent pool and our library of titles, and have
emerged as one of the industry's leaders. We intend to continue to expand our
resources through acquisitions, strategic relationships and key license
transactions. We expect to focus our acquisition strategy on increasing our
development capacity through the acquisition of


or investment in selected experienced development firms, and expanding our
intellectual property library through licenses and strategic relationships with
intellectual property owners.

* Less than 1%.

(1)  Percentages are based on 33,889,016 shares of common stock that were issued
     and outstanding as of October 10, 2001.

(2)  This amount does not include the following, which are more fully described
     below: (i) 153,992 shares of Common Stock subject to certain software
     program delivery and revenue and certain escrow requirements; and
     (ii)15,399 shares of Common Stock to be issued to certain Selling
     Stockholders upon completion of certain software program delivery and
     revenue requirements.

     The Company entered into an agreement and plan of merger (the "Merger
Agreement") with Activision Publishing Inc., Treyarch Invention LLC
("Treyarch"), Don Likeness, Peter Akemann, Eric Steinmann, Shawn Capistrano and
Eric Steinmann, as representative of the persons listed on Schedule 1 thereto
(the "Members"). The transaction contemplated by the Merger Agreement was
consummated on October 1, 2001.

     Pursuant to a warranty escrow agreement an aggregate of 153,993 shares of
Common Stock, or twenty-two percent (22%) of the total number of shares of
Common Stock issued have been deposited in an escrow account in connection with
the transaction (the "Escrow Shares"). The Escrow Shares have been deposited in
order to ensure that the representations, warranties and covenants made by the
former Treyarch Members under the Merger Agreement are not breached and in order
to provide a source of indemnification to Activision pursuant to the Merger
Agreement. In addition, the Escrow Shares are subject to release from escrow
upon fulfillment of certain software program delivery and ranking requirements
and certain revenue requirements, as described in the Merger Agreement. In the
event certain of the software program delivery and ranking requirements are met,
certain of the Selling Stockholders are entitled to receive, in addition to the
Escrow Shares, 15,399 shares of Common Stock.


     We will issue a prospectus supplement to reflect any increase in the number
of shares of Common Stock offered for sale in the event the conditions described
above are fulfilled.

     Prior to the acquisition of Treyarch by Activision, Treyarch was a party to
various development agreements with Activision. Other than such contracts and
the fact that the Selling Stockholders are employees of Treyarch, which became a
wholly owned subsidiary of Activision on October 1, 2001 pursuant to the Merger
Agreement, none of the Selling Stockholders has had a material relationship with
the Company within the past three years.

                          DESCRIPTION OF CAPITAL STOCK

     The authorized capital stock of Activision consists of 125,000,000 shares
of Common Stock, $.000001 par value, 4,500,000 shares of Preferred Stock,
$.000001 par value and 500,000 shares of Series A Junior Preferred Stock,
$.000001 par value. As of October 10, 2001, there were 33,889,016 shares of
Activision Common Stock issued and outstanding, no Activision Preferred Stock
issued and outstanding and no Activision Junior Preferred Stock issued and

     Each outstanding share of Common Stock entitles the holder to one vote on
all matters submitted to a vote of stockholders, including the election of
directors. There is no cumulative voting in the election of directors, which
means that the holders of a majority of the outstanding shares of Common Stock
can elect all of the directors then standing for election. Subject to
preferences which may be applicable to any outstanding shares of Preferred Stock
and Junior Preferred Stock, holders of Common Stock are entitled to such
distributions as may be declared from time to time by directors of the Company
out of funds legally available therefor. The Company has not paid, and has no
current plans to pay, dividends on its Common Stock. The Company intends to
retain all earnings for use in its business.

     Holders of Common Stock have no conversion, redemption or preemptive rights
to subscribe to any securities of the Company. All outstanding shares of Common
Stock are fully paid and nonassessable. In the event of any liquidation,
dissolution or winding-up of the affairs of the Company, holders of Common Stock
will be entitled to share ratably in the assets of the Company remaining after
provision for payment of liabilities to creditors and preferences applicable to
outstanding shares of Preferred Stock and Junior Preferred Stock.

     The rights, preferences and privileges of holders of Common Stock are
subject to the rights of the holders of any outstanding shares of Preferred
Stock and Junior Preferred Stock. As of October 10, 2001, the Company had
approximately 3,800 stockholders of record, excluding banks, brokers and
depository companies that are stockholders of record for the account of
beneficial owners.

     The transfer agent for the Common Stock of the Company is Continental Stock
Transfer & Trust Company, 2 Broadway, New York, New York 10004.

                              PLAN OF DISTRIBUTION

     The Common Stock may be sold from time to time by the Selling Stockholders,
or by pledgees, donees, transferees or other successors in interest. Such sales
may be made on one or more exchanges or in the over-the-counter market, or
otherwise, at prices and at terms then prevailing or at prices related to the
then current market price, or in negotiated transactions. The shares may be sold
from time to time in one or more of the following transactions, without
limitation: (a) a block trade in which the broker or dealer so engaged will
attempt to sell the shares as agent but may position and resell a portion of the
block as principal to facilitate the transaction, (b) purchases by a broker or
dealer as principal and resale by such broker or dealer or for its account
pursuant to the Prospectus, as supplemented, (c) an exchange distribution in
accordance with the rules of such exchange, and (d) ordinary brokerage
transactions and transactions in which the broker solicits

purchasers. In addition, any securities covered by this Prospectus which qualify
for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to
this Prospectus, as supplemented. From time to time the Selling Stockholders may
engage in short sales, short sales against the box, puts and calls and other
transactions in securities of the Company or derivatives thereof, and may sell
and deliver the shares in connection therewith.

     From time to time Selling Stockholders may pledge their shares pursuant to
the margin provisions of their respective customer agreements with their
respective brokers. Upon a default by a Selling Stockholder, the broker may
offer and sell the pledged shares of Common Stock from time to time as described

     All expenses of registration of the Common Stock (other than commissions
and discounts of underwriters, dealers or agents), estimated to be approximately
$28,809, shall be borne by the Company. As and when the Company is required to
update this Prospectus, it may incur additional expenses in excess of this
estimated amount.

                                  LEGAL MATTERS

     Certain legal matters in connection with the shares of Common Stock offered
hereby have been passed upon by Robinson Silverman Pearce Aronsohn & Berman
LLP, New York, New York. Kenneth L. Henderson, one of our directors, is a
managing partner of Robinson Silverman. In addition, Robinson Silverman owns
approximately 10,000 shares of our common stock.


     Our consolidated financial statements and financial statement schedule as
of March 31, 2000, and for each of the years in the two-year period ended March
31, 2000, have been incorporated by reference herein and in the registration
statement in reliance upon the report of KPMG LLP, independent certified public
accountants, incorporated by reference herein, and upon the authority of said
firm as experts in accounting and auditing.

     The consolidated financial statements as of and for the year ended March
31, 2001 incorporated by reference in this prospectus have been so incorporated
by reference in reliance on the report of PricewaterhouseCoopers LLP,
independent accountants, given on the authority of said firm as experts in
auditing and accounting.

     We replaced KPMG as our principal accountant with PricewaterhouseCoopers,
effective March 20, 2001. The action was recommended by the Audit Committee of
our board of directors and approved by our board of directors. During our two
fiscal years ended March 31, 2000 and three subsequent interim periods, there
were no disagreements with KPMG LLP on any matter of accounting principles or
practice, financial statement disclosure, or auditing scope or procedure, which,
if not resolved to the satisfaction of KPMG LLP, would have caused it to make a
reference to the subject matter of the disagreement in connection with its
report. KPMG LLP's reports on our financial statements for each of the years in
the two-year period ended March 31, 2000 did not contain an adverse opinion or a
disclaimer of opinion, nor were they qualified or modified as to uncertainty,
audit scope or accounting principles.
