                                  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 fiscal 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 fiscal
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 recently launched a new platform.
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. In November


2001, Microsoft made the first shipments of its Xbox console system in North
America, and Microsoft released its Xbox console system in Europe and Japan in
the first quarter of calendar year 2002. In November 2001, Nintendo made the
first shipments of its Nintendo GameCube console system in North America, and
Nintendo released its GameCube console system in Europe in May 2002.
Additionally, in June 2001, Nintendo launched its Game Boy Advance hand held
device. Shortages of these platforms or lack of consumer acceptance could
adversely affect our sales of products for these platforms. Current sales of
some 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. An 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


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.; Sega Enterprises, 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., and Microsoft Corporation compete directly
with us in the development of software titles for their respective 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 the consideration we pay to vendors. 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 fiscal 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 fiscal 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 fiscal 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
fiscal 2000 (26% of our consolidated net revenues).

We may permit our customers to return our products and to receive pricing
concessions which could reduce our net revenues and results of operations.

     We are exposed to the risk of product returns and price protection with
respect to our distributors and retailers. We may permit product returns from or
grant price protection to our customers under certain conditions. Return
policies allow distributors and retailers to return defective, shelf-worn and
damaged products in accordance with terms granted. Price protection policies,
when granted 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 we may place limits on
product returns and price protection, we could be forced to accept 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 fiscal 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 fiscal 1999, 2000 and 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


regulatory requirements, tariffs and other barriers. Additionally, foreign sales
which are made in local currencies may fluctuate. Presently, we engage in
limited 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

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) under
certain circumstances 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 a 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 stock.

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

     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.

                                   THE COMPANY

     We are a leading international publisher of interactive entertainment
software products. We have built a company with a diverse portfolio of products
that spans a wide range of categories and target markets and that is used on a
variety of game hardware platforms and operating systems. We have created,
licensed and acquired a group of highly recognizable brands which we market to a
growing variety of consumer demographics. Our products cover the action,
adventure, extreme sports, racing, role playing, simulation and strategy game
categories. We offer our products in versions which operate on the Sony
PlayStation, Sony PlayStation 2, Nintendo 64, Nintendo GameCube, Microsoft Xbox
and Sega Dreamcast console systems, the Nintendo Game Boy Color and Game Boy
Advance hand held devices, as well as on personal computers. Over the next few
years, we plan to produce many titles for the recently released Sony PlayStation
2, Microsoft Xbox and Nintendo GameCube console systems and Game Boy Advance
hand held device. 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, Nintendo 64,
Nintendo GameCube, Microsoft Xbox and Sega Dreamcast console systems, Nintendo
Game Boy and Game Boy Advance hand held devices and the personal computer. 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 sales.

     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, Blade, Iron Man and
Fantastic Four. 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, Shaun
Murray in wakeboarding and Travis Pastrana in pro motorcross biking.

     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 we have a capital
investment. 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 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 thirteen 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.

distributions as may be declared from time to time by directors of the Company

                              PLAN OF DISTRIBUTION

     The Common Stock may be sold from time to time by the Selling Stockholder,
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
by one or more of the following, 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
Stockholder 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. Sales may
also take place from time to time through brokers pursuant to pre-arranged sales
plans intended to qualify under SEC Rule 10b5-1.

     From time to time the Selling Stockholder may pledge his shares pursuant to
the margin provisions of his customer agreements with his brokers. Upon a
default by the Selling Stockholder, the broker may offer and sell the pledged
shares of Common Stock from time to time as described under the heading "Plan of
Distribution" in this Prospectus, as supplemented.

and discounts of underwriters, dealers or agents), estimated to be approximately
$5,000, 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.

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

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.
