ITEM 1: BUSINESS
 
  Silicon Gaming, Inc. ("SGI" or the "Company") is engaged in the design and
development of what it believes will be the next generation of interactive
slot machines for use in casinos and other gaming establishments. The
Company's product combines an advanced multimedia gaming platform with
software-based games that the Company believes will be more engaging and
entertaining than other gaming devices currently available and will, as a
result, generate increased gaming revenue per device ("win per machine") for
the casino operator. On March 20, 1997, the Company's product was granted
final approval by the Nevada Gaming Commission, thereby allowing the Company
to ship its first product for commercial trial. As of December 31, 1996, the
Company had received nonbinding commitments to install and evaluate its gaming
platform from Bally's Las Vegas, Bally's Park Place Casino, Boulder Station
Hotel and Casino, Caesars Palace Las Vegas, California Hotel & Casino, Circus
Circus Hotel & Casino, Excalibur Hotel Casino, the Flamingo Hilton, Grand
Casino Biloxi, Grand Casino Gulfport, Grand Casino Tunica, Hard Rock Hotel &
Casino, Harrah's Las Vegas, ITT Sheraton Desert Inn, ITT Sheraton Tunica, Las
Vegas Hilton, Luxor Hotel Casino, MGM Grand Hotel/Casino, New York-New York
Hotel/Casino, Palace Station Hotel & Casino, Stardust Resort & Casino, Station
Casino Kansas City, St. Charles Riverfront Station, Stratosphere Hotel &
Casino, Texas Station and Treasure Island, each of which has agreed to install
and evaluate from 8 to 40 of the Company's machines. Collectively, these
casinos have agreed to install over 500 units. During the first quarter of
1997, the Company commenced installations of its product in certain Las Vegas
casinos.
 
  The Company's gaming platform features high resolution video presented
across the full surface of a large touchscreen display. The games feature high
quality animation, video clips, digital sound and a level of visual appeal and
interactivity that the Company believes is unattainable by the current
generation of slot machines. The Company is attempting to maximize the
entertainment value offered on the two-dimensional surface of the video screen
by providing multiple levels of achievement within select games, so that,
through successful play over a period of time, a player may advance to a
bonusing sequence and win additional jackpots. Utilizing these features, SGI
believes that its product will encourage longer and more frequent periods of
play by existing slot machine customers and attract new gaming customers who
are seeking greater entertainment value than that offered by the current
generation of slot machines. In addition, the Company has designed its
machines with a number of features, such as play stoppage entertainment(TM),
modular components and the Company's Machine Management System(TM) software,
which provides casino operators streamlined access to the advanced diagnostic,
configuration, and accounting capabilities of the machine.
 
INDUSTRY BACKGROUND
 
  The U.S. gaming machine market is currently dominated by reel-based slot
machines, which were broadly introduced in the 1960s, when the free-spinning
reel was made possible by advances in electro-mechanical circuitry. The free-
spinning reel enabled manufacturers to create different versions of the same
product by varying such things as the number of reels, the number of stops on
each reel and the number and variety of payoff combinations. The 1980s saw the
introduction of virtual reel "stepper" technology which allowed for a greater
number of stops, or outcomes, on a reel, enabling casino operators to offer
larger jackpots due to the lower likelihood of their being hit. Another
significant development was the installation of electronic memory in machines,
allowing players to keep an "account" of credits on the machine consisting of
the initial amount inserted plus winnings minus losses. Since the player did
not have to reinsert coins for every pull of the handle, the number of pulls
per hour was increased significantly, and players tended to rewager much of
the amounts won, raising the total win per machine. Except for the addition of
features such as bill acceptors and player tracking systems, the technology
employed by slot machines in the 1970s and 1980s still predominates in
current-generation machines.
 
  In the 1980s, hardware and software advances allowed for application of
video graphics to gaming devices. Using these techniques, International Game
Technology ("IGT") was the first company to introduce video
 
                                       2
<PAGE>
 
poker. Video poker offers slot players two important advantages. First, the
game is interactive, since the player has to decide which cards to hold or
discard during the hand. This feature allows the outcome to be influenced
somewhat by the player, an attribute unavailable on reel-based machines.
Second, the use of a video screen allows machine manufacturers to develop more
interesting and attractive graphics than are available on reel-based slot
machines. Recently, Bally Gaming International, Inc. ("Bally Gaming") expanded
the capabilities of video-based devices when it introduced GameMaker, a
popular video-based machine which offers the player a choice of up to ten
different games on a single machine. The Company believes that the popularity
of video poker and multi-game machines suggests that customers may be
receptive to a more complex and interactive slot experience.
 
  In the late 1980s, a category of slot machine games called "progressives"
was introduced and became very popular. The progressive configuration
generally consists of traditional reel-based machines linked together by a
computer network that allows them to share a common jackpot which is usually
much larger than the jackpot that a single, unlinked machine could support.
Progressive jackpots are usually several million dollars, and have
occasionally exceeded $10 million. Progressives may be linked locally within a
bank of a few machines, across an entire casino, or across an entire state.
IGT is the dominant competitor in the progressives market.
 
  According to industry sources, casino gaming revenue in the United States in
1991, 1992, 1993, 1994 and 1995 were approximately $9.0 billion, $9.9 billion,
$12.6 billion, $14.0 billion and $18.0 billion, respectively, and continued
growth was forecasted for 1996 and 1997. Slot machines, video gaming machines
and similar devices are the dominant source of gaming revenue for casino
operators in most U.S. markets. Slot revenue as a percentage of total gaming
revenue in 1996 was 63% in Nevada and 69% in Atlantic City. Jurisdictions
where gaming has recently been legalized have reported similar statistics. For
example, in 1996, slot machines accounted for 69% of casino revenue in
Illinois and 62% in Louisiana. In addition to constituting the largest portion
of gaming revenue, slot revenue is more profitable than table games for casino
operators, since slot machines require much lower labor costs.
 
  All casino games offer the same underlying proposition: the opportunity to
win money in varying amounts and with varying frequency, but with the
statistical certainty of losing money to the casino operator over an extended
period of time. With slot machines, the prospect of winning can be varied
across the spectrum from many small jackpots won frequently to one very large
jackpot won very rarely. Players' risk/reward appetites will determine what
type of machine they will want to play, and the nature of the payoffs can be
deduced from the "pay table," a chart that graphically shows how much can be
won based on various outcomes and various amounts of money wagered.
Notwithstanding the differences in jackpot frequency and size, however, all
slot machines retain a net amount of the money wagered through them over time.
This amount is referred to as the "hold" and is generally expressed as a
percentage of the amount of money inserted into the machine, which is called
the "handle." The hold percentage in any given machine is preset by the
manufacturer based on specifications from the casino, subject to legal
parameters in some jurisdictions, and may differ from machine to machine on a
casino floor.
 
  The Company believes that slot machines offer their owners an attractive
return on investment. In January 1996, the average win per machine per day,
defined as the average amount of money inserted into the machine less the
average jackpot payoffs, on the Las Vegas Strip was $101. A new slot machine
from a major manufacturer, equipped with player tracking and slot accounting
software, costs approximately $8,000 and generally has a useful life exceeding
five years. At this price, a new slot machine earning the Las Vegas Strip
average would recoup its purchase price in 80 days. While certain markets have
lower average wins per day than the Las Vegas Strip, many other markets have
win per day figures that are significantly higher. For example, in January
1996, the Trump Taj Mahal casino in Atlantic City reported win per machine per
day of $151, Foxwoods Hotel and Casino in Ledyard, Connecticut reported win
per machine per day of $359, and Harrah's riverboat casino in Joliet, Illinois
reported win per machine per day of $411.
 
  Because of the importance of slot win to casino operators and the high
returns available from an investment in slot machines, the Company believes
that casino operators are willing to try new slot machine products that
 
                                       3
<PAGE>
 
offer the prospect of higher win per machine per day. At the same time,
operators are motivated to remove any machines that are performing
significantly below expectations. SGI believes that its machines will generate
win per machine per day that will exceed that of the average installed
machine, and therefore, it believes that it will be able to penetrate the
market, generate orders for its machines and maintain a share of casino floor
space. However, the tastes and playing styles of slot players are difficult to
predict with certainty, and there can be no assurance that SGI's machines will
outperform competing machines in win per machine per day.
 
  Growth in demand for slot machines has historically been driven by the
opening of new casinos, including casinos in jurisdictions where gaming has
recently been legalized. However, in recent years, the legalization of gaming
in new jurisdictions has been significantly reduced; therefore, demand based
on new openings will be largely limited to new projects in existing markets.
Several new projects are under construction or have been announced in Las
Vegas, Atlantic City, on the Gulf Coast and in the Midwest.
 
  While the physical useful life of a slot machine can be up to a decade or
more, casino operators have tended to replace machines on a cycle closer to
every five years. Also, the development of certain new features which offer
the prospect of significantly increased slot earnings, such as the advent of
bill acceptors in the 1990s, can encourage operators to replace machines even
more rapidly.
 
  Because of the slowing in demand from new casino projects, and because the
large number of machines installed during the high growth period of the early
1990's will soon be reaching their normal replacement time, the Company
believes that the new slot machine sales in the replacement category will
surpass gaming machine sales for new installations in the near future. The
Company believes that it will more easily penetrate the replacement segment of
the slot machine market than the market for new installations, since the
operators of a newly-opened casino may be less likely to risk overall success
on the trial of a relatively unproven product.
 
  The market for slot machines outside of North America is relatively small,
with the exception of Australia, and is generally difficult to forecast. In
addition, international markets have often served as an outlet for used
machines. While SGI intends to take advantage of certain opportunities in
international markets, the Company intends to pursue these markets only after
successfully establishing its market position in North America.
 
SGI PARADIGM
 
  The Company believes it has identified an underlying structure to the
typical slot play session, consisting of four distinct phases: initial
attraction; initial play; extended play; and completion. During each of these
phases, certain factors determine whether the player advances from one phase
to the next. SGI has sought to understand these four phases so that (1) it can
maximize the likelihood that a slot customer will play its machine, (2) once
playing, the player will stay at the machine for a long period of time, and
(3) the player will return frequently to play the same or similar SGI
machines.
 
    Initial Attraction. The Company believes that the factors that determine
  whether a customer will initiate play include the machine's visual appeal,
  the payout structure, promotional graphics and other external attributes
  that convey the impression that the machine would be entertaining to play.
 
    Initial Play. Once play commences, the customer makes an initial decision
  about whether to continue. The Company believes that factors affecting this
  decision include whether the game meets the customer's entertainment
  expectations, conforms to his or her payout expectations, is easy to
  understand and play, and is relatively trouble-free.
 
    Extended Play. Extended play occurs when the player has become fully
  engaged in the entertainment experience provided by the game. Because
  extended play eliminates idle machine time, this phase is strongly desired
  by casino operators. Once the player commits to extended play, any
  interruption in play, such as a fill, malfunction or reset for change
  service, becomes an excuse to end the session.
 
    Completion. Completion is the final phase of the play session and can
  occur, for example, when the customer runs out of money, runs out of time,
  or achieves a targeted jackpot level. One of the Company's
 
                                       4
<PAGE>
 
  goals in designing its gaming platform is to increase the likelihood that
  the player will leave the completion phase with the desire to play the same
  machine at a later time based on a number of factors, including winnings
  and entertainment value.
 
PRODUCT
 
  The Company has developed a product it believes represents the next
generation of interactive gaming devices for use in casinos and other gaming
establishments in the United States and worldwide. The Company's product
utilizes multimedia technologies to present casino games that it believes will
be more engaging and entertaining than other gaming devices currently
available. The Company's games feature high-resolution video presented across
the full surface of a large touchscreen display. The games feature high
quality animation, video clips, digital sound and a level of game
attractiveness and interaction that the Company believes is unavailable from
and unachievable by current-generation slot machines. Unlike traditional
"hardware-dominant" slot machines, the principal features of each of SGI's
proprietary games are software based, allowing SGI and its customers to adapt
their game offerings to evolving technologies and changing consumer tastes
without structural change to, or replacement of, the gaming platform.
 
 Platform, Hardware and Other Physical Attributes
 
  SGI's gaming platform is designed to resemble a traditional slot machine in
many respects. The machine occupies the same footprint as a traditional slot
machine and is of roughly the same general size and shape, enabling casino
operators to replace traditional slot machines with SGI's machines without any
reconfiguration of the casino floor. The most distinctive attribute of the
product is its vertically-oriented, 26-inch-diagonal touchscreen video
monitor. A player's sense of interactivity is heightened by the ability to
make all the required decisions on the screen, within the game itself. For
players who are uncomfortable or unfamiliar with touchscreen devices, however,
all of the traditional slot machine controls have been included as well. Thus,
a player can control the game by using the touchscreen, by pushing a series of
buttons similar to those found on current slot or video poker machines, or by
pulling a handle as on traditional slot machines. Coin handling mechanisms,
bill acceptors, card readers and other devices related to cash deposit, credit
and win payout are similar to those used in current gaming machines. The
music, voice and other audible features of the Company's games are played on a
digital sound system.
 
  The principal electronic hardware used in SGI's gaming platform consists of
high-end multimedia and personal computer ("PC") components. The central
processing unit is an Intel 133-MHz Pentium chip. This processor is
accompanied by a variety of video and auxiliary controllers, some of which
have been developed exclusively for use with the Company's product. To achieve
optimal multimedia performance from the system, the Company's machine uses 64
megabytes of random access memory. Storage for the vast array of audio and
visual media elements of the games, as well as the product software itself, is
provided by a high-capacity 4 gigabyte hard disk drive. These components are
connected internally by a high-speed PCI bus. SGI's reliance on sophisticated
full-motion video and high-quality audio presentations requires the use of
state-of-the-art technology, and SGI expects to upgrade the performance of its
platform periodically as higher-performance components become available. SGI
machines are intended to be easily reconfigurable in the field through the
replacement of hardware components such as computer motherboards and video and
auxiliary controllers, allowing casino operators to upgrade hardware in a cost
effective manner.
 
  The Company's gaming platform is assembled almost entirely from off-the-
shelf hardware, which the Company anticipates will reduce the chance of a
parts shortage and will enable the Company to continue to manufacture its
devices using state-of-the-art components as PC and multimedia technologies
advance. There can be no assurance, however, that the Company will continue to
enjoy a reliable supply of hardware components. Moreover, certain components
such as the touchscreen display and monitor are manufactured by single sources
and may be particularly susceptible to interruptions in supply. Although SGI
does develop proprietary components in order to meet certain specialized
requirements of its platform, the Company intends
 
                                       5
<PAGE>
 
to primarily use commercially available computer hardware components as a
regular part of its product development process.
 
  SGI's machines have been designed to accept future hardware upgrades that
will take advantage of networking capabilities. When networked, two or more
machines can be linked, facilitating activities such as group play,
tournaments and progressives. For example, a particular group of platforms can
be configured to announce to players that a tournament will begin at a
particular time and allow each player the option to participate. Similarly,
platforms can be configured so that when one machine hits a jackpot, a player
at another machine can win a bonus award; the two affected platforms then
display a coordinated audio/video simulation of a coin flying out of one tray
and into the other. The Company believes that features of this kind will
promote interaction among players at adjacent platforms and thereby maintain
player interest for longer periods of time.
 
  SGI has incorporated numerous features into its gaming platform that are
designed both to attract the player and to maintain his or her interest over
an extended period of time. For example, SGI's gaming platform can be
programmed to allow for a free spin following a specified number of
unsuccessful attempts in order to ensure a minimum level of reward to the
player. Similarly, SGI's machines are capable of running promotional or
entertainment video programs during play stoppages such as those caused by a
hopper refill, malfunction or request for change. These features have been
designed to reduce the likelihood that a player will leave the machine during
a play stoppage event. These features may also provide an additional revenue
or promotional source to the operator by providing a medium for commercial
messages.
 
  SGI's gaming platform employs modular construction at almost every level,
facilitating upgrades and minimizing machine down-time. Such modularity
permits the rapid exchange of components for upgrades or to replace defective
parts. Using SGI's proprietary Machine Management System, casino personnel can
run a variety of diagnostic programs or review detailed performance data
directly from the gaming platform itself. In the case of a malfunctioning
component, a casino technician can quickly restore play simply by swapping out
the failed component with a new one. The modularity of SGI's platform will
also facilitate upgrades of hardware components such as card readers and bill
validators as new components become available. The Company believes that these
features may allow casino operators to reduce platform down-time and shorten
the time required to fix any malfunction, thereby increasing the time the
platform is available for play and reducing the risk that a player will elect
to terminate a gaming session as a result of play stoppage.
 
  To address the desire of slot machine operators to respond efficiently to
service calls that cause stoppages in play, SGI's slot machine incorporates
what SGI believes to be a significant improvement over the traditional
"candle" (the light on the top of a slot machine). SGI's multi-state candle
uses variable color and strobe rate displays to convey more information than a
simple call for help. Different colors signify different service calls, and
changes in strobe rate signify how long the customer has been waiting,
features that the Company believes will assist the casino floor staff in
prioritizing responses to customer needs.
 
 Games and Other Software
 
  While SGI believes that the design of its machine and its hardware
components are important to its operation and its ability to foster initial
and extended play, it believes that the most important factor affecting the
success of its platform will be the games themselves and the software that
controls those games. The majority of the Company's development efforts to
date have been devoted to hardware, system software and game development, and
the Company expects that, in the future, game development will be its
principal development activity.
 
  The SGI machine, called Odyssey(TM), is a multi-game platform. The Company's
initial release of its product includes nine gaming options consisting of six
separate game themes, play stoppage entertainment and the Machine Management
System. The Company intends to develop at least six new games per year.
 
 
                                       6
<PAGE>
 
  The Company's games have been designed to present traditional casino games
with the benefit of video and audio enhancements that are afforded by the
Company's use of high-end multimedia hardware. While the underlying game may
consist of a traditional casino game such as poker, keno or a reel-based slot
machine, the game itself is only one aspect of the entertainment experience.
Some of SGI's games embed an engaging and entertaining story. As examples,
Fort Knox, SGI's basic three-reel slot game, places the experience in the
context of a player trying to gain access to Fort Knox, with payouts being
depicted as gold coins spilling from a secure vault. In Phantom Belle, a video
poker game, the player is pitted against the disembodied hands of a ghostly
dealer aboard a 19th century riverboat.
 
  Some of the games that the Company plans to offer include the following:
 
    Fort Knox--A variation on the traditional three-reel slot game in which
  the player enters the main vault room of Fort Knox and spins the giant
  combination reels. If the symbols match those on the pay table, a series of
  vault doors swing open, spilling coins into the tray. If the player matches
  the numbers to the bonus combination, he will be given access to the main
  vault's interior, where he can win an additional jackpot.
 
    Phantom Belle--The Phantom Belle series provides players with a variety
  of traditional five-card poker games, enhanced by thematic and rich playing
  experience. Played on a 19th century haunted river boat, cards are dealt by
  the floating hands of a phantom dealer.
 
    Krazy Keno--A version of keno in which balls shoot into the air through a
  transparent tube. If enough of the flying balls land on the spots selected
  by the player, he wins a jackpot according to the pay table.
 
    Win-O-Matic--A classic three-reel slot game reminiscent of that played on
  mechanical devices in the 1950s featuring traditional reel symbols like
  cherries, lemons and oranges. Win-O-Matic combines simplicity of play with
  the flexibility of modern game percentaging technology.
 
    Dazzling Diamonds--This variation on the traditional, three-reel game
  features a large photo-realistic diamond and a host of sounds. When the
  dazzling diamond symbol appears on the pay line, it doubles all jackpot
  combinations.
 
    Star Spangled Keno--This rendition of a traditional keno game features a
  patriotic theme. The play is faster and the rules simpler than in
  traditional keno. If enough numbers are matched, a colorful marching band
  appears to celebrate the jackpot.
 
  The Company believes that the combination of its attractive machine, high-
level graphics and sound, bonusing features and the pursuit of an interesting
and entertaining story will make SGI's product outperform conventional slot
machines at each of the four phases of slot machine play--initial attraction,
initial play, extended play and completion.
 
    Initial Attraction. The Company believes that the physical appearance of
  its machines will be more attractive than conventional machines and will
  entice customers to play. In addition to the physical attributes of its
  machines, the Company has included a suite of video images that run when
  the machine is not being played. These include short, animated vignettes
  from the Company's games and "help" screens, as well as a menu page
  identifying all of the games available on that particular machine.
  Information regarding any game can be viewed through the push of a "Help"
  button. These merchandising segments feature the same quality of graphics,
  sound, video and animation that distinguish all of SGI's games.
 
    Initial Play. In the initial play period, SGI believes it is necessary to
  quickly engage the customer in the story line and to avoid any confusion,
  unfamiliarity or negative experiences which might cause the customer to
  discontinue play. For this reason, the Company has produced an initial
  suite of games that consist of enhanced versions of traditional casino
  games, including reel-based slot games, so that the rules of the game will
  be well known. SGI intends to present these games using enhanced graphics
  and sound to enrich the play experience, but will not change the
  fundamental characteristics or objective of the game. In addition, the
  machine will offer traditional game controls for those players unfamiliar
  or uncomfortable with the touchscreen interface.

    Extended Play. The Company believes that the enhancements it has made to
  traditional casino games by the addition of high level graphics, sound,
  animation and storyline will encourage extended play, as well as more
  frequent play, and thereby generate greater win per machine than the
  unenhanced versions of these games available in conventional machines.
 
    A significant feature which the Company believes will contribute
  significantly to extended play, is the introduction of advanced play levels
  in which a player, by virtue of having played a certain amount of time or
  achieved a certain number of jackpots at one level, gains access to a bonus
  sequence in which larger jackpots become available. For example, in Fort
  Knox a 10-digit master combination to the main vault appears in the play
  field. At random time intervals during play, another digit on the main
  vault lock is matched. When the main vault is opened, a player may select
  from one of three vault drawers to receive an additional bonus.
 
    To facilitate extended play, the Company has developed a sophisticated
  on-line tutorial, help features and play stoppage entertainment. The
  tutorial and help features generally consist of video inserts designed to
  provide orientation, instruction and assistance before or during the game.
  In Fort Knox, for example, Seymour Bucks, the main security guard at Fort
  Knox, can appear if there is a call for change and provide assistance. If
  there is a machine play stoppage, a hopper fill requirement, or a jackpot
  requiring the player to be hand paid, Professor Jack Potts, the absent-
  minded slot genius, will appear to explain the cause of the malfunction and
  present trivia, other game information, video clips advertising the
  casino's amenities or upcoming promotions and tournaments, or other
  commercial material.
 
    Completion. The Company believes that the principal events that lead to
  completion of play include the player's running out of money, running out
  of time or achieving a targeted jackpot level. The Company believes that
  the unique features and entertainment value of its games will entice
  players to remain in the extended play phase for longer periods of time
  than are generally fostered by current generation slot machines. Moreover,
  the design of the Company's platform and games is intended to provide an
  entertainment experience that will encourage repeated play.
 
  In addition to features that are designed to enhance the entertainment value
of SGI's machine and its ability to generate incremental revenue for the
casino, SGI's platform incorporates proprietary features that are designed to
overcome certain hurdles that may be involved in the licensing of a slot
machine design, as well as to facilitate easy maintenance and supervision by
casino personnel. These features are as follows:
 
    Random Number Generator. At the core of every gaming machine is a random
  number generator that determines the outcome of every gaming proposition.
  To eliminate what the Company believes are some of the impediments to
  randomness that characterize random number generators, SGI engaged Dr.
  Evangelos Yfantis, a recognized authority in the field of random number
  algorithms, to develop a proprietary random number generator algorithm for
  the Company. The Company has filed a U.S. patent application with respect
  to its algorithm.
 
    Software Authentication. A critical element of all gaming machines is an
  authentication mechanism to determine that the software being used is
  identical to the software that has been approved by regulatory authorities
  and is operating correctly. This is necessary to ensure that the game being
  played corresponds exactly to that designed by the manufacturer and
  approved by regulatory authorities. Traditional slot machines need to be
  authenticated manually, a process usually performed only after a sizable
  jackpot award. The infrequency of checks offer greater opportunities to
  breach the security of traditional machines. The Company has developed a
  proprietary authentication process which leverages the advanced
  capabilities of the Company's machine to verify the integrity of a game
  each time it is selected for play. This process combines sophisticated
  authentication routines developed by RSA Data Security, Inc. with a
  proprietary methodology developed by the Company. The Company's
  authentication process provides continual checking of the machine's
  software for both accidental corruptions or malicious attempts to cheat the
  machine. Any detected anomalies will cause the machine to signal the loss
  of integrity immediately. The Company has filed for patent protection for
  certain aspects of its authentication methodology.
 
 
                                       8
<PAGE>
 
    Machine Management System. The Company's Machine Management System is
  designed to provide easy access to the configuration, accounting, and
  diagnostic capabilities of the machine. The Machine Management System's
  accounting functions are designed to provide a rapid, easy-to-interpret
  report of all key machine metering data, as well as detailed accounting and
  statistics, on a game-by-game basis. The Machine Management System uses the
  full benefit of the machine's touchscreen to make installation and setup of
  the machine easier than traditional slot machines. The diagnostic programs
  comprise a user-friendly maintenance and troubleshooting system that allows
  casino floor personnel to quickly and effectively assess the cause of a
  play stoppage or other malfunctions or to examine transaction history where
  the validity of a jackpot or other transaction must be verified. For
  example, if a player asserts that the machine has not given full credit for
  a jackpot or has not properly recorded a cash input, a floor manager, using
  the touchscreen and a key, can access comprehensive data to review
  transaction and event history. With this information, the floor manager can
  rapidly evaluate the merit of the player's claim and take appropriate
  action. In this way, disputes can be quickly resolved at the machine's
  location without the operator having to consult back office records or
  review surveillance videotape.
 
PRODUCT DEVELOPMENT
 
  The Company's product development efforts, particularly its game development
efforts, will be critical to its success in the gaming market. Research and
development expenses have increased significantly since inception and are
expected to continue to increase in the future. At December 31, 1996, 40 of
the Company's 98 full-time employees were engaged in research and development.
 
  Ideas for new games are derived from customer needs as perceived by the
Company or ascertained through the Company's market research and direct
feedback from slot machine operators. The initial designs for the Company's
games are conceived by a design team, which outlines the appearance and
features of each game. A prototype is developed by a production team that
includes a producer, product manager, artists, computer graphics engineers and
entertainment software engineers. The game is then evaluated by SGI's
marketing and sales staff, after which it is modified into its final form. The
Company estimates that the development of a typical game takes approximately
three to eight months and costs approximately $100,000 to $300,000.
 
  SGI is seeking to develop a variety of specific games which management
believes will appeal to casino operators and their customers. Currently, the
Company is engaged in the development of games based on traditional slot
machine games such as animated reel slots, video poker and keno. The Company
is also in the process of creating slot machine versions of popular casino
games such as blackjack and roulette. These initial games are intended to help
customers look beyond the unfamiliar technology to recognizable game types. In
addition, the Company is developing a line of Magic Windows(TM) type games.
The proprietary Magic Windows game type introduces decision making into a
traditional reel-slot experience by allowing the player to select from a
number of available symbols.
 
  Some of the games currently under development include the following:
 
    Meteors--A Magic Windows version of a traditional three-reel game in
  which the player fires three laser blasts at a meteor field. As the meteors
  explode and disintegrate, reel symbols are revealed. Symbol combinations
  matching the pay table win jackpot awards. As a bonus feature, at random
  intervals, the player is sent into "hyperspace" mode in which all jackpots
  are doubled.
 
    Roulette Royale--A slot version of roulette in which the player can place
  bets in the same fashion as in a traditional roulette game. The player then
  "spins" the wheel on the video screen to determine the outcome based on the
  number or color at which the wheel stops.
 
    Buccaneer Gold--A three-reel slot machine game in which the player aims
  his cannons at three combination wheels set in the flank of a pirate ship.
  When symbols on the wheels are matched according to the pay table, the
  player wins, and the screen displays a jackpot celebration such as gold
  coins being spilled from a treasure chest or fired from a musket. Upon
  certain combinations on the reel, a pirate sticks a dagger into the deck
  railing; an accumulation of five daggers leads to a bonusing sequence.
 
                                       9
<PAGE>
 
  Mayan Riches--A Magic Windows version of a three-reel game in which the
  player finds himself in front of a large pyramid uncovered in an
  archaeological dig. Embedded in the pyramid are nine stone reels, over
  which stone doors close as the reels begin to spin. The player is required
  to pick three of the doors to reveal hidden symbols, the object being to
  match one of the jackpot combinations on the pay table. After the outcome
  is revealed, the remaining symbols are uncovered and the game is ready to
  resume.
 
  Completion of the games under development is subject to various risks and
uncertainties. Such games may be subject to further creative decisions that
could alter the game implementation or marketing considerations that could
result in a shift of the Company's development focus to different types of
games altogether. Successful completion of any game will also be subject to
risks typically associated with the creative process, such as the risk that
the Company's creative team will be unable to achieve the desired results in
terms of the game's entertainment quality.
 
  Over time, SGI expects to introduce additional games that offer a wider
range of gaming experiences as players become more familiar with the
capabilities of advanced video gaming platforms. For example, the Company may
introduce games with sports attributes such as baseball, football or golf. The
Company also anticipates developing some of its games for progressive formats
in which the Company's machines would be networked to support a common jackpot
that is significantly larger than that which a stand-alone machine could
offer.
 
  During the year ended March 31, 1995, the nine month period ended December
31, 1995 and the year ended December 31, 1996, the Company's research and
development expenses were $1,539,000, $3,137,000 and $7,030,000, respectively.
 
SALES AND MARKETING
 
  The ultimate success of SGI's gaming platform depends on its acceptance by
casino operators and casino patrons. The Company believes that, from the point
of view of casino operators, the attractiveness of any gaming platform depends
on win per machine, ease of upgrade, maintenance and game change and
information management. The Company believes that, from the casino patron's
perspective, the attractiveness of a platform is a function of entertainment
value. SGI's sales and marketing strategy is to generate product sales by
highlighting the advantages presented by its gaming platform to casino
operators, such as potential for increased win per machine, and by developing
processes focused on key operator values. SGI's marketing strategy also
targets casino players and will focus on developing brand recognition for
SGI's games, which the Company believes can be accomplished through the
development of proprietary games that deliver greater entertainment value for
the gaming dollar.
 
  SGI intends to position itself as a partner with casino operators in
establishing the next generation of wagering entertainment. The Company
recognizes the important role that casino operations personnel play in
establishing market acceptance for new machines and thus will target this
group with products, sample game platforms and training.
 
  Because SGI's games are software-based, SGI believes that there will be a
significant opportunity for game customization and the development of games
for the exclusive use of one or more casino customers. It is already
commonplace for casinos to ask that conventional slot machines be customized
with the casino's logo or theme. SGI believes that it can significantly exceed
this level of customization by inserting the casino's logo or theme right in
the game, by presenting images of the casino's other games and amenities, or
by creating a new game entirely based on the casino's theme. The Company
intends to charge customers a fee for this work.
 
 Three-Phase Product Introduction
 
  The Company intends to introduce its product and begin its marketing and
sales efforts in a controlled and deliberate manner, following a three-phase
program through 1998:
 
  1996: In the initial phase, the Company's primary objective was to complete
  development of the product and to have it licensed and available for sale
  in one or more jurisdictions. The Company was approved by
 
                                      10
<PAGE>
 
  the Nevada Gaming Control Board to conduct a 60-day field trial of its
  product in December 1996. Final approval was granted on March 20, 1997,
  allowing the Company to make its first customer shipment into Nevada. The
  Company has received nonbinding commitments to install and evaluate its
  gaming platform from several leading Las Vegas casinos.
 
  1997: The Company commenced installations of its product in certain Las
  Vegas casinos during the first quarter of 1997. However, the Company's plan
  is to limit the number of machines it sells in 1997 so that it can
  carefully monitor the reactions of gaming patrons and casino customers to
  its platform, game software and product support features. The Company
  expects to incorporate any changes it deems advisable based on these
  surveys into revised and new versions of its platform and games. At the
  same time, the Company will be building its sales and support
  infrastructure in order to properly support customers when full roll-out
  planned for 1998 takes place.
 
  1998: In 1998, the Company expects to broadly market and sell its platform
  and software-based games. Because of the restraints imposed by its product
  introduction program, the Company currently believes that 1998 will be the
  first year in which a reasonable assessment of the commercial potential of
  its product can be made.
 
  The successful introduction of the Company's product will be subject to
substantial risks and uncertainties, including the risk of technical or
manufacturing difficulties, the possibility that the SGI platform will not
receive the anticipated market acceptance and possible delays or hurdles
associated with licensing of the Company's product in various jurisdictions.
 
  The Company will be required to be licensed in each jurisdiction in which it
expects to sell product. As of January 31, 1997, the Company had filed
applications to sell its product in Nevada, New Jersey, Mississippi, Missouri
and Colorado. To date, the Company has received both corporate approval and
approval to sell its product in Nevada and has also received corporate
approval in Mississippi, Missouri and Colorado. The Company has also filed an
application for approval of its gaming platform in Mississippi and New Jersey
and with Gaming Laboratories International, Inc., an independent testing
facility which grants product approval for many jurisdictions worldwide. See
"Gaming Regulation and Licensing."
 
  Although the Company plans to file applications in other jurisdictions,
there can be no assurance that the Company will be ready to file future
applications or that any licenses will be granted on a timely basis, or at
all.
 
 Sales Organization
 
  The Company is building a sales and support organization to handle sales and
after-sales service to the Company's casino customers. As of December 31,
1996, the Company had 15 employees in its sales and support area, and the
Company plans to continue to build its sales and support organization
throughout 1997. The Company intends to sell its product by developing close
working relationships with casino operators, through SGI's direct sales
representatives and support team. Where appropriate, the Company may enter
into distribution arrangements or other strategic relationships to enter
additional markets.
 
  The Company has entered into non-binding commitments for trial shipments
with casinos, principally in Las Vegas. In accordance with industry practice,
these casinos will accept such units, without payment to the Company, for a
45-day installation and evaluation period. During this period, each casino
operator will evaluate the performance of the machine against other machines
on its floor or available for purchase and will make a determination whether
or not to purchase units at the end of the trial period. At the end of the
trial period, such customers may purchase the trial machines. If a casino
declines to purchase a machine, SGI will remove the machine from that casino's
premises. The Company has received nonbinding commitments to install and
evaluate its gaming platform from Bally's Las Vegas, Bally's Park Place
Casino, Boulder Station Hotel and Casino, Caesars Palace Las Vegas, California
Hotel & Casino, Circus Circus Hotel & Casino, Excalibur Hotel Casino,
 
                                      11
<PAGE>
 
the Flamingo Hilton, Grand Casino Biloxi, Grand Casino Gulfport, Grand Casino
Tunica, Hard Rock Hotel & Casino, Harrah's Las Vegas, ITT Sheraton Desert Inn,
ITT Sheraton Tunica, Las Vegas Hilton, Luxor Hotel Casino, MGM Grand
Hotel/Casino, New York-New York Hotel/Casino, Palace Station Hotel & Casino,
Stardust Resort & Casino, Station Casino Kansas City, St. Charles Riverfront
Station, Stratosphere Hotel & Casino, Texas Station and Treasure Island, each
of which has agreed to install and evaluate from 8 to 40 of the Company's
machines. Collectively, these casinos have agreed to install over 500 units.
During the first quarter of 1997, the Company commenced installations of its
product in certain Las Vegas casinos.
 
 Pricing
 
  The Company intends to offer its product to casino operators and other
potential purchasers using two alternative purchase programs, consisting
either of (i) the sale of the hardware unit bundled with a specific package of
games and other software for a fixed price, or (ii) the sale of the hardware
unit alone combined with a renewable one-year software license, including
games. The Company expects that the prices of both of the packages described
above will be higher than the current prices for most conventional slot
machines. The Company may also consider cost-sharing and revenue-sharing
arrangements. Because software-based gaming machines represent a new
development for the casino industry, potential purchasers' preferences in this
area have not been determined. The Company plans to evaluate its pricing and
sales methods and to incorporate changes as appropriate. The Company believes
that license revenue from game software may eventually constitute a
substantial portion of its revenue.
 
COMPETITION
 
  The current slot machine market is highly competitive and is dominated by a
small number of manufacturers, some of whom have significantly greater
financial and other resources than the Company. The Company believes that the
principal competitive factors in this market are the appeal of the machine to
players, knowledge of customer requirements and player preferences, service,
support and training, distribution, name and product recognition and price.
The principal competitors in the slot machine market are IGT and Bally Gaming.
IGT may be viewed as a dominant competitor, with a 1996 market share estimated
at 75%; Bally Gaming's 1996 market share is estimated at 15%. Additional
competitors or potential competitors include WMS Industries Inc., Video
Lottery Consultants, Aristocrat Leisure Industries, Universal Distributing,
Sigma Games, Casino Data Systems, Acres Gaming Inc. and Innovative Gaming
Corporation of America. Companies in historically unrelated industries, such
as Sega Enterprises LTD ("Sega"), have technological resources that could
offer them a competitive advantage in developing multimedia-based gaming
machines. There can be no assurance that other companies in the video game or
multimedia market will not successfully enter the market for video slot
machines, nor can there be any assurance that the manufacturers of traditional
slot machines will not develop products that are superior to, or that achieve
greater market acceptance than, the Company's product. In general, the
Company's existing competitors, as well as many potential new competitors,
have significantly greater financial and technical resources than the Company,
as well as more established customer bases and distribution channels, which
may afford them competitive advantages. Increased competition is likely to
result in price reductions, reduced operating margins and loss of market
share, any of which could materially and adversely affect the Company's
business, operating results or financial condition.
 
PROPRIETARY RIGHTS AND LICENSES
 
  The Company's computer programs and technical know-how are both novel and
proprietary, and management believes that they can best be protected by use of
technical devices to protect the computer programs and by enforcement of
contracts and covenants not to compete with certain employees and others with
respect to the use of the Company's proprietary information and trade secrets.
The Company has registered copyrights with respect to various aspects of its
games, and has filed several U.S. patent applications for protection of
certain technology it has created or licensed. These patent applications cover
various aspects of the gaming machine hardware and software. No assurance can
be given that the pending applications will be granted, nor can there be any
assurance that the patents will not be infringed or that others will not
develop technology that does not violate such patents.
 
                                      12
<PAGE>
 
  SGI has developed a proprietary method of authentication for disk drive-
based gaming machines, for which it has submitted a patent application. Since
modern gaming technology requires the handling and processing of large amounts
of on-line data, establishing a method for storing and retrieving data that
meets the approval requirements of the regulatory authorities while meeting
adequate standards of internal performance requires use of a comprehensive
authentication system to assure both the casino operator and requisite gaming
authorities that the software is an exact copy of what was generated by SGI
and approved by such gaming authorities.
 
  In addition, SGI owns exclusive rights to the algorithm for its random
number generator, the key component of the Company's gaming machines which
determines the outcome of each proposition. SGI's algorithm, which may have
uses outside the gaming industry, was developed by Dr. Evangelos A. Yfantis, a
professor of Computer Science at the University of Nevada, Las Vegas.
 
  In developing its games, the Company relies on certain software that it
licenses from Duck Corporation ("Duck") on a nonexclusive basis. This license
may be terminated by Duck only in the event of a material breach of its terms
by the Company or in the event of a bankruptcy petition with respect to the
Company.
 
EMPLOYEES
 
  As of December 31, 1996, the Company had 98 full-time employees, including
40 in research and development. The Company also retains independent
contractors to provide certain services, primarily in connection with its
product development activities. The Company and its full-time employees are
not subject to any collective bargaining agreements and the Company believes
that its relations with its employees are good. From time to time the Company
has retained actors and/or "voice over" talent to perform in certain of the
Company's games, and expects to continue this practice in the future. The
Company's future success depends in large part on its ability to attract and
retain management and other key personnel.
 
MANUFACTURING
 
  The Company intends to manufacture product in-house or contract product
assembly to a licensed manufacturer. All of the Company's initial
manufacturing will be performed at the Palo Alto and Mountain View facilities.
The Company intends to continue investing significantly in leasehold
improvements and manufacturing equipment at these facilities. In 1996, the
Company established its manufacturing process and commenced commercial
production. As of December 31, 1996, the company had 19 full-time employees in
manufacturing and had manufacturing development expenses of $2,458,000. The
Company expects the manufacturing process to consist primarily of assembly of
components obtained from third-party suppliers and testing software systems
and applications.
 
GAMING REGULATION AND LICENSING
 
  General Regulation of Shareholders of Publicly Traded Corporations. In most
jurisdictions, any beneficial owner of the Company's Common Stock is subject
on a discretionary basis to being required to file applications with gaming
regulatory authorities, be investigated and found suitable or qualified as
such. In addition, shareholders whose holdings of Common Stock exceed certain
designated percentages are subject to certain reporting and qualification
requirements imposed by state and federal gaming regulators and, any
shareholder, if found to be unsuitable, may be required to immediately dispose
of its holdings of Common Stock. See "--Nevada Regulatory Matters," "--
Missouri Regulatory Matters," "--Colorado Regulatory Matters," "--New Jersey
Regulatory Matters," and "--Mississippi Regulatory Matters."
 
  Nevada Regulatory Matters. The Company must obtain a registration, license,
approval or finding of suitability, and equipment approval in all
jurisdictions before it can offer gaming devices for sale to licensed gaming
operations within those jurisdictions. The licensing process usually involves
the licensing or approval of certain officers, directors, and shareholders of
the corporation, and approval of the specific product that the Company wants
to offer for sale. On June 19, 1996 the Nevada Commission registered SGI and
licensed Silicon Gaming-Nevada ("SGI-Nevada"), a wholly-owned subsidiary of
SGI, as a manufacturer, distributor and operator of a slot machine route. The
Company's initial public offering was also approved by the Nevada Commission
on June 19, 1996. On March 20, 1997, the Nevada Commission granted final
approval of the Company's product for sale to licensed casinos in Nevada.
 
                                      13
<PAGE>
 
  The manufacture, sale and distribution of gaming devices for use or play in
Nevada or for distribution outside of Nevada, the manufacture and distribution
of associated equipment for use in Nevada, and the ownership and operation of
slot machine routes in Nevada are subject to: (i) the Nevada Gaming Control
Act and the regulations promulgated thereunder (collectively, "Nevada Act");
and (ii) various local ordinances and regulations. Such activities are subject
to the licensing and regulatory control of the Nevada Commission, the Nevada
Board, and various local, city and county regulatory agencies (collectively
referred to as the "Nevada Gaming Authorities").
 
  The laws, regulations and supervisory procedures of the Nevada Gaming
Authorities are based upon declarations of public policy which are concerned
with, among other things: (i) the prevention of unsavory or unsuitable persons
from having a direct or indirect involvement with gaming, or manufacturing or
distribution of gaming devices at any time or in any capacity; (ii) the strict
regulation of all persons, locations, practices, associations and activities
related to the operation of licensed gaming establishments and the manufacture
or distribution of gaming devices and equipment; (iii) the establishment and
maintenance of responsible accounting practices and procedures; (iv) the
maintenance of effective controls over the financial practices of licensees,
including the establishment of minimum procedures for internal fiscal affairs
and the safeguarding of assets and revenue, providing reliable record keeping
and requiring the filing of periodic reports with the Nevada Gaming
Authorities; (v) the prevention of cheating and fraudulent practices; and (vi)
the provision of a source of state and local revenue through taxation and
licensing fees. Change in such laws, regulations and procedures could have an
adverse effect on the Company's operations.
 
  On June 19, 1996 the Company was registered by the Nevada Commission as a
publicly-traded corporation (a "Registered Corporation"), and SGI-Nevada was
approved as a manufacturer, distributor and operator of a slot machine route.
On March 20, 1997, the Nevada Commission granted final approval of the
Company's product. Such gaming approvals require the periodic payment of fees
and taxes and are not transferable. As a Registered Corporation, the Company
is required periodically to submit detailed financial and operating reports to
the Nevada Commission and furnish any other information which the Nevada
Commission may require. No person may become a shareholder of, or receive any
profit from SGI-Nevada without first obtaining licenses and approvals from the
Nevada Gaming Authorities. The Company and SGI-Nevada have applied for, and in
some cases received, the various registrations, approvals, permits and
licenses in order to engage in manufacturing, distribution and slot route
activities in Nevada.
 
  All gaming devices that are manufactured, sold or distributed for use or
play in Nevada, or for distribution outside of Nevada, must be manufactured by
licensed manufacturers and distributed or sold by licensed distributors. All
gaming devices manufactured for use or play in Nevada must be approved by the
Nevada Commission before distribution or exposure for play. The approval
process for gaming devices includes rigorous testing by the Nevada Board, a
field trial and a determination as to whether the gaming device meets strict
technical standards that are set forth in the regulations of the Nevada
Commission. Associated equipment must be administratively approved by the
Chairman of the Nevada Board before it is distributed for use in Nevada.
 
  The Nevada Gaming Authorities may investigate any individual who has a
material relationship to, or material involvement with, a Registered
Corporation or its subsidiaries in order to determine whether such individual
is suitable or should be licensed as a business associate of a gaming
licensee. Officers, directors and certain key employees of the Company and
SGI-Nevada are required to file applications with the Nevada Gaming
Authorities and may be required to be licensed or found suitable by the Nevada
Gaming Authorities. The Nevada Gaming Authorities may deny an application for
licensing for any cause which they deem reasonable. A finding of suitability
is comparable to licensing, and both require submission of detailed personal
and financial information followed by a thorough investigation. The applicant
for licensing or a finding of suitability must pay all the costs of the
investigation. Changes in licensed positions must be reported to the Nevada
Gaming Authorities and in addition to their authority to deny an application
for a finding of suitability or licensure, the Nevada Gaming Authorities have
jurisdiction to disapprove a change in a corporate position. On June 19, 1996
SGI's Chief Executive Officer, Chief Financial Officer, the required directors
and SGI-Nevada's sole officer and director were found suitable by the Nevada
Commission.
 
 
                                      14
<PAGE>
 
  If the Nevada Gaming Authorities were to find an officer, director or key
employee unsuitable for licensing or unsuitable to continue having a
relationship with SGI or SGI-Nevada, the Company would have to sever all
relationships with such person. In addition, the Nevada Commission may require
the Company or SGI-Nevada to terminate the employment of any person who
refuses to file appropriate applications. Determination of suitability or of
questions pertaining to licensing are not subject to judicial review in
Nevada.
 
  The Company and SGI-Nevada will be required to submit detailed financial and
operating reports to the Nevada Commission. Substantially all material loans,
leases, sales of securities and similar financing transactions by the Company
will be required to be reported to or approved by the Nevada Commission.
 
  If it were determined that the Nevada Act was violated by the Company or
SGI-Nevada, the registration and gaming licenses it holds could be limited,
conditioned, suspended or revoked, subject to compliance with certain
statutory and regulatory procedures. In addition, the Company, SGI-Nevada and
the persons involved could be subject to substantial fines for each separate
violation of the Nevada Act at the discretion of the Nevada Commission.
Limitation, conditioning or suspension of any gaming license could (and
revocation of any gaming license would) materially adversely affect the
Company's gaming operations.
 
  Any beneficial holder of a Registered Corporation's voting securities,
regardless of the number of shares owned, may be required to file an
application, be investigated, and have his suitability determined as a
beneficial holder of the Registered Corporation's voting securities if the
Nevada Commission has reason to believe that such ownership would otherwise be
inconsistent with the declared policies of the State of Nevada. The applicant
must pay all costs of investigation incurred by the Nevada Gaming Authorities
in conducting any such investigation.
 
  The Nevada Act requires any person who acquires beneficial ownership of more
than 5% of a Registered Corporation's voting securities to report the
acquisition to the Nevada Commission. The Nevada Act requires that beneficial
owners of more than 10% of a Registered Corporation's voting securities apply
to the Nevada Commission for a finding of suitability within thirty days after
the Chairman of the Nevada Board mails the written notice requiring such
filing. Under certain circumstances, an "institutional investor," as defined
in the Nevada Act, which acquires more than 10% but not more than 15%, of the
Registered Corporation's voting securities may apply to the Nevada Commission
for a waiver of such finding of suitability if such institutional investor
holds the voting securities for investment purposes only. An institutional
investor shall not be deemed to hold voting securities for investment purposes
unless the voting securities were acquired and are held in the ordinary course
of business as an institutional investor and not for the purpose of causing,
directly or indirectly, the election of a majority of the members of the board
of directors of the Registered Corporation, any change in the Registered
Corporation's corporate charter, bylaws, management, policies or operations of
the Registered Corporation, or any of its gaming affiliates, or any other
action which the Nevada Commission finds to be inconsistent with holding the
Registered Corporation's voting securities for investment purposes only.
Activities which are not deemed to be inconsistent with holding voting
securities for investment purposes only include: (i) voting on all matters
voted on by shareholders; (ii) making financial and other inquiries of
management of the type normally made by securities analysts for informational
purposes and not to cause a change in its management, policies or operations;
and (iii) such other activities as the Nevada Commission may determine to be
consistent with such investment intent. If the beneficial holder of voting
securities who must be found suitable is a corporation, partnership or trust,
it must submit detailed business and financial information including a list of
beneficial owners. The applicant is required to pay all costs of
investigation.
 
  Any person who fails or refuses to apply for a finding of suitability or a
license within thirty days after being ordered to do so by the Nevada
Commission or the Chairman of the Nevada Board, may be found unsuitable. The
same restrictions apply to a record owner if the record owner, after request,
fails to identify the beneficial owner. Any shareholder found unsuitable and
who holds, directly or indirectly, any beneficial ownership of the Common
Stock beyond such period of time as may be prescribed by the Nevada Commission
may be guilty of a criminal offense. The Company will be subject to
disciplinary action if, after it receives notice that a person is unsuitable
to be a shareholder or to have any other relationship with the Company or SGI-
 
                                      15

Nevada, the Company (i) pays that person any dividend or interest upon voting
securities of the Company, (ii) allows that person to exercise, directly or
indirectly, any voting right conferred through securities held by that person,
(iii) pays remuneration in any form to that person for services rendered or
otherwise, or (iv) fails to pursue all lawful efforts to require such
unsuitable person to relinquish his voting securities including, if necessary,
the immediate purchase of said voting securities for cash at fair market
value.
 
  The Nevada Commission may, in its discretion, require the holder of any debt
security of a Registered Corporation to file applications, be investigated and
be found suitable to own the debt security of a Registered Corporation. If the
Nevada Commission determines that a person is unsuitable to own such security,
then pursuant to the Nevada Act, the Registered Corporation can be sanctioned,
including the loss of its approvals, if without the prior approval of the
Nevada Commission, it: (i) pays to the unsuitable person any dividend,
interest, or any distribution whatsoever; (ii) recognizes any voting right by
such unsuitable person in connection with such securities; (iii) pays the
unsuitable person remuneration in any form; or (iv) makes any payment to the
unsuitable person by way of principal, redemption, conversion, exchange,
liquidation, or similar transaction.
 
  The Company will be required to maintain a current stock ledger in Nevada
which may be examined by the Nevada Gaming Authorities at any time. If any
securities are held in trust by an agent or by a nominee, the record holder
may be required to disclose the identity of the beneficial owner to the Nevada
Gaming Authorities. A failure to make such disclosure may be grounds for
finding the record holder unsuitable. The Company will also be required to
render maximum assistance in determining the identity of the beneficial owner.
The Nevada Commission has the power to require the stock certificates of the
Company to bear a legend indicating that the securities are subject to the
Nevada Act. However, the Nevada Commission has not imposed such a requirement
on the Company to date, but it is unknown whether the Nevada Commission will
impose such a requirement on the Company in the future.
 
  As a Registered Corporation, the Company may not make a public offering of
its securities, such as an IPO, without the prior approval of the Nevada
Commission if the securities or proceeds therefrom are intended to be used to
construct, acquire or finance gaming facilities in Nevada, or to retire or
extend obligations incurred for such purposes. Approval of a public offering,
if given, does not constitute a finding, recommendation or approval by the
Nevada Commission or the Nevada Board as to the accuracy or adequacy of the
prospectus or the investment merits of the securities offered. Any
representation to the contrary is unlawful.
 
  Changes in control of a Registered Corporation through merger,
consolidation, stock or asset acquisitions, management or consulting
agreements, or any act or conduct by a person whereby he obtains control, may
not occur without the prior approval of the Nevada Commission. Entities
seeking to acquire control of a Registered Corporation must satisfy the Nevada
Board and the Nevada Commission in a variety of stringent standards prior to
assuming control of such Registered Corporation. The Nevada Commission may
also require controlling shareholders, officers, directors and other persons
having a material relationship or involvement with the entity proposing to
acquire control, to be investigated and licensed as part of the approval
process relating to the transaction.
 
  The Nevada legislature has declared that some corporate acquisitions opposed
by management, repurchases of voting securities and corporate defense tactics
affecting Nevada corporate gaming licensees, and Registered Corporations that
are affiliated with those operations, may be injurious to stable and
productive corporate gaming. The Nevada Commission has established a
regulatory scheme to ameliorate the potentially adverse effects of these
business practices upon Nevada's gaming industry and to further Nevada's
policy to: (i) assure the financial stability of corporate gaming licensees
and their affiliates; (ii) preserve the beneficial aspects of conducting
business in the corporate form; and (iii) promote a neutral environment for
the orderly governance of corporate affairs. Approvals are, in certain
circumstances, required from the Nevada Commission before the Registered
Corporation can make exceptional repurchases of voting securities above the
current market price thereof and before a corporate acquisition opposed by
management can be consummated. The Nevada Act also requires prior approval of
a plan of recapitalization proposed by the Registered Corporation's Board of
Directors
 
                                      16

in response to a tender offer made directly to the Registered Corporation's
shareholders for the purposes of acquiring control of the Registered
Corporation.
 
  License fees and taxes, computed in various ways depending on the type of
gaming or activity involved, are payable to the State of Nevada and to the
counties and cities in which gaming operations are to be conducted. Depending
upon the particular fee or tax involved, these fees and taxes are payable
either monthly, quarterly or annually and are based upon either: (i) a
percentage of the gross revenue received; or (ii) the number of gaming devices
operated. Annual fees are also payable to the State of Nevada for renewal of
licenses as a manufacturer, distributor and operator of a slot machine route.
 
  Any person who is licensed, required to be licensed, registered, required to
be registered, or is under common control with such persons (collectively,
"Licensees"), and who proposes to become involved in a gaming venture outside
of Nevada, is required to deposit with the Nevada Board, and thereafter
maintain, a revolving fund in the amount of $10,000 to pay the expenses of
investigation by the Nevada Board of their participation in such foreign
gaming. The revolving fund is subject to increase or decrease in the
discretion of the Nevada Commission. Thereafter, Licensees are required to
comply with certain reporting requirements imposed by the Nevada Act.
Licensees are also subject to disciplinary action by the Nevada Commission if
they knowingly violate any laws of the foreign jurisdiction pertaining to the
foreign gaming operation, fail to conduct the foreign gaming operation in
accordance with the standards of honesty and integrity required of Nevada
gaming operations, engage in activities that are harmful to the state of
Nevada or its ability to collect gaming taxes and fees, or employ a person in
the foreign operation who has been denied a license or finding of suitability
in Nevada on the ground of personal unsuitability.
 
  In the future, SGI intends to seek the necessary registrations, licenses,
approvals, and findings of suitability for the Company, its product and its
personnel in other jurisdictions throughout the world. However, there can be
no assurances that such registrations, licenses, approvals or findings of
suitability will be obtained. Many other jurisdictions in which the Company
wishes to do business require various licenses, permits, and approvals in
connection with the manufacture and/or distribution of gaming devices,
typically involving restrictions similar in most respects to those of Nevada.
 
  Missouri Regulatory Matters. Gaming was originally authorized in the state
of Missouri in November 1992. On April 29, 1993, new legislation (the
"Missouri Act") was enacted which replaced the 1992 legislation. In January
1994 the Missouri Supreme Court handed down a decision which held that the
operation of certain games of chance such as traditional slot machines was
prohibited by the constitution of the state of Missouri. On November 8, 1994,
the people of Missouri voted in favor of an amendment to the Missouri
constitution to allow slot machine gaming in the state. The Missouri Act
provides for the licensing and regulation of excursion gambling boat
operations on the Mississippi and Missouri Rivers in the state of Missouri and
the licensing and regulation of persons who distribute gaming equipment and
supplies to gaming licensees. An excursion gambling boat is a boat, ferry or
other floating facility on which gaming is allowed. The Missouri Act limits
the loss per individual on each excursion to $500, but does not otherwise
limit the amount which may be wagered on any bet or the amount of space in the
vessel which may be utilized for gaming.
 
  The Missouri Act is to be implemented and enforced by a five-member Missouri
Commission. The Missouri Commission is empowered to issue such number of
riverboat gaming licenses as it determines to be appropriate. A gaming license
cannot be granted to any gaming operator unless the voters in such operator's
"home dock" city or county have authorized gaming activities on gaming
riverboats.
 
  On September 1, 1993, the Missouri Commission adopted rules and regulations
(the "Missouri Regulations") governing the licensing, operation and
administration of riverboat gaming in the state of Missouri and the form of
application for such licensure. The Missouri Regulations generally provide for
four types of licenses--a Class A owner's license; a Class B operator's
license; a supplier's license; and an occupational license. In addition, the
Missouri Regulations remain subject to amendment and interpretation, and may
further limit or otherwise adversely affect the Company and its Missouri
gaming operations.
 
                                      17
<PAGE>
 
  Directors and certain officers and key persons of the Company and Silicon
Gaming-Missouri ("SGI-Missouri"), a wholly-owned subsidiary of SGI, must file
personal disclosure forms with the gaming license application and must be
found suitable by the Missouri Commission. Further, the Missouri Regulations
require that all employees of SGI-Missouri who are involved in gaming
operations and who are employed on the licensed premises must file
applications for and receive Missouri gaming occupational licenses. The
Missouri regulations require disclosure by the Company and SGI-Missouri of any
person or entity holding any direct or indirect ownership interest in SGI-
Missouri. SGI-Missouri is also required to disclose the names of the holders
of all of the Company's and SGI-Missouri's debt including a description of the
nature and terms of such debt. The Missouri Commission may, in its sole
discretion, request additional information with respect to such holders.
Missouri suppliers' gaming licenses must be renewed annually for a fee of
$5,000 or such greater amount as may be determined by the Commission. On
November 8, 1996, SGI-Missouri was granted a temporary supplier's license by
the Missouri Commission.
 
  Under Missouri law, gaming licenses are not transferable, and under the
Missouri Regulations the transfer of (i) any ownership interest in a privately
held business entity or (ii) a 5% or greater interest in a publicly traded
company directly or indirectly holding a Missouri gaming license is prohibited
without the approval of the Missouri Commission. Further, without the prior
approval of the Missouri Commission, the Missouri Regulations prohibit
withdrawals of capital, loans, advances or distribution of any assets in
excess of 5% of accumulated earnings by a license holder to anyone with an
ownership interest in the license holder.
 
  The Missouri Regulations specifically provide that any action of the
Missouri Commission shall not indicate or suggest that the Missouri Commission
has considered or passed in any way on the marketability of the applicant or
licensee's securities, or on any other matter, other than the applicant or
licensee's suitability for licensure under Missouri law. A Missouri gaming
license holder can be disciplined in Missouri for gaming-related acts
occurring in another jurisdiction which result in disciplinary action in the
other jurisdiction.
 
  The Missouri Commission has broad powers to require additional disclosure by
an applicant during the processing of a gaming application, to deny gaming
licensure and to administratively fine or suspend or revoke a gaming license
for failure to comply with or for violation of the Missouri Act or Missouri
Regulations.
 
  Colorado Regulatory Matters. The State of Colorado created the Division of
Gaming (the "Division") within the Department of Revenue to license,
implement, regulate and supervise the conduct of limited gaming. The Director
of the Division, under the supervision of a five-member Colorado Commission,
has been granted broad power to ensure compliance with the Colorado
Regulations. The Director may inspect, without notice, impound or remove any
gaming device. He may examine and copy any licensee's records, may investigate
the background and conduct of licensees and their employees, and may bring
disciplinary actions against licensees and their employees. He also may
conduct detailed background investigations of persons who loan money to the
Company.
 
  The Colorado Commission is empowered to issue five types of gaming and
gaming-related licenses. The failure or inability of the Company or Silicon
Gaming-Colorado, Inc. (the "Colorado subsidiary"),or others associated with
the Company or the Colorado subsidiary, to obtain or maintain necessary gaming
licenses will have a material adverse affect on the operations of the Company.
All persons employed by the Company and the Colorado subsidiary and involved,
directly or indirectly, in gaming operations in Colorado also are required to
obtain a Colorado gaming license. All licenses must be renewed annually. On
January 24, 1997, the Company and its wholly-owned subsidiary, Silicon Gaming-
Colorado, Inc., were granted a manufacture and distribution license by the
Colorado Limited Gaming Commission.
 
  In addition, pursuant to the Colorado Regulations, no manufacturer or
distributor of slot machines may have an interest in any casino operator,
allow any of its officers to have such an interest, employ any person if such
person is employed by a casino operator, or allow any casino operator or
person with a substantial interest therein to have an interest in a
manufacturer's or distributor's business. The Commission has ruled that a
person does not have a "substantial interest" if it directly or indirectly has
less than a five percent (5%) interest in such
 
                                      18
<PAGE>
 
voting securities of a licensee. Some Division Staff informally have
interpreted the Regulations to prohibit a casino operator from having any
interest in a slot machine manufacturer or distributor.
 
  Under the Colorado Regulations, any person or entity having any direct or
indirect interest in a gaming licensee or an applicant for a gaming license,
including, but not limited to, the Company and shareholders of the Company,
may be required to supply the Colorado Commission with substantial
information, including, but not limited to, background information, source of
funding information, a sworn statement that such person or entity is not
holding his interest for any other party, and fingerprints. Such information,
investigation and licensing as an "associated person" automatically will be
required of all persons (other than certain institutional investors discussed
below) which directly or indirectly own ten percent (10%) or more of a direct
or indirect legal, beneficial or voting interest in the Colorado subsidiary,
through their ownership in the Company. Such persons must report their
interest and file appropriate applications within 45 days after acquiring such
interest. Persons directly or indirectly having a five percent (5%) or more
interest (but less than 10%) in the Colorado Subsidiary, through their
ownership in the Company, must report their interest to the Colorado
Commission within ten (10) days after acquiring such interest and may be
required to provide additional information and to be found suitable. If
certain institutional investors provide certain information to the Colorado
Commission, such investors, at the Colorado Commission's discretion, may be
permitted to own up to 14.99% of the Colorado Subsidiary, through their
ownership in the Company, before being required to be found suitable. All
licensing and investigation fees will have to be paid for by the person in
question. The associated person investigation fee currently is $48.00 per
hour.
 
  The Colorado Commission also has the right to request information from any
person directly or indirectly interested in, or employed by, a licensee, and
to investigate the moral character, honesty, integrity, prior activities,
criminal record, reputation, habits and associations of (i) all persons
licensed pursuant to the Colorado Limited Gaming Act, (ii) all officers,
directors and shareholders of a licensed privately held corporation, (iii) all
officers, directors and shareholders holding either a five percent (5%) or
greater interest or a controlling interest in a licensed publicly traded
corporation, (iv) all general partners and all limited partners of a licensed
partnership, (v) all persons who have a relationship similar to that of an
officer, director or shareholder of a corporation (such as members and
managers of a limited liability company), (vi) all persons supplying financing
or loaning money to any licensee connected with the establishment or operation
of limited gaming, and (vii) all persons having a contract, lease or ongoing
financial or business arrangement with any licensee, where such contract,
lease or arrangement relates to limited gaming operations, equipment, devices
or premises.
 
  In addition, under the Colorado Regulations, every person who is a party to
a "gaming contract" with an applicant for a license, or with a licensee, upon
the request of the Colorado Commission or the Director, promptly must provide
to the Colorado Commission or Director all information which may be requested
concerning financial history, financial holdings, real and personal property
ownership, interests in other companies, criminal history, personal history
and associations, character, reputation in the community, and all other
information which might be relevant to a determination whether a person would
be suitable to be licensed by the Colorado Commission. Failure to provide all
information requested constitutes sufficient grounds for the Director or the
Colorado Commission to require a licensee or applicant to terminate its
"gaming contract" (as defined below) with any person who failed to provide the
information requested. In addition, the Director or the Colorado Commission
may require changes in "gaming contracts" before an application is approved or
participation in the contract is allowed. A "gaming contract" is defined as an
agreement in which a person does business with or on the premises of a
licensed entity.
 
  An application for licensure or suitability may be denied for any cause
deemed reasonable by the Colorado Commission or the Director, as appropriate.
Specifically, the Colorado Commission and the Director must deny a license to
any applicant who (i) fails to prove by clear and convincing evidence that the
applicant is qualified, (ii) fails to provide information and documentation
requested; (iii) fails to reveal any fact material to qualification, or
supplies information which is untrue or misleading as to a material fact
pertaining to qualification; (iv) has been, or has any director, officer,
general partner, shareholder, limited partner or other person who has a
financial or equity interest in the applicant who has been, convicted of
certain crimes, including
 
                                      19
<PAGE>
 
the service of a sentence upon conviction of a felony in a correctional
facility, city or county jail, or community correctional facility or under the
state board of parole or any probation department within ten years prior to
the date of the application, gambling-related offenses, theft by deception or
crimes involving fraud or misrepresentation, is under current prosecution for
such crimes (during the pendency of which license determination may be
deferred), is a career offender or a member or associate of a career offender
cartel, or is a professional gambler; or (v) has refused to cooperate with any
state or federal body investigating organized crime, official corruption or
gaming offenses.
 
  If the Colorado Commission determines that a person or entity is unsuitable
to own interests in the Company, then the Company or the Colorado Subsidiary
may be sanctioned, which may include the loss by the Company or the Colorado
Subsidiary of their respective approvals and licenses.
 
  The Colorado Commission does not need to approve in advance a public
offering of securities, but rather requires a filing of notice and additional
documents with regard to such public offering prior to such public offering.
The Company has filed the required notice with the Colorado Commission. Under
the regulations, the Colorado Commission may, in its discretion, require
additional information and prior approval of such public offering.
 
  In addition, the Colorado Regulations prohibit a licensee or affiliated
company thereof, such as the Company, from paying dividends, interest or other
remuneration to any unsuitable person, or recognizing the exercise of any
voting rights by any unsuitable person. Further, the Company may repurchase
the shares of anyone found unsuitable at the lesser of the cash equivalent to
the original investment in the Company or the current market price. Further,
the regulations require anyone with a material involvement with a licensee,
including a director or officer of a holding company, such as the Company, to
file for a finding of suitability if required by the Colorado Commission.
 
  In addition to its authority to deny an application for a license or
suitability, the Colorado Commission has jurisdiction to disapprove a change
in corporate position of a licensee and may have such authority with respect
to any entity which is required to be found suitable by the Colorado
Commission. The Colorado Commission has the power to require the Company and
the Colorado Subsidiary to suspend or dismiss managers, officers, directors
and other key employees or sever relationships with other persons who refuse
to file appropriate applications or whom the authorities find unsuitable to
act in such capacities, and may have such power with respect to any entity
which is required to be found suitable.
 
  A person or entity may not sell, lease, purchase, convey or acquire a
controlling interest in the Company without the prior approval of the Colorado
Commission. The Company may not sell any interest in the Colorado Subsidiary
without the prior approval of the Colorado Commission.
 
  Limited gaming facilities in Colorado must not exceed certain gaming square
footage limits as a total of each floor and the full building. Casinos in
Colorado may operate only between 8:00 a.m. and 2:00 a.m., and may permit only
individuals 21 years or older to gamble in the casino. The law permits slot
machines, blackjack and poker, with a maximum single bet of $5.00. Casinos may
not provide credit to their gaming patrons.
 
  The Colorado Constitution permits a gaming tax of up to 40% on adjusted
gross gaming proceeds. The Colorado Commission has set a gaming tax rate of 2%
on adjusted gross gaming proceeds of up to and including $2 million, 8% over
$2 million and including $4 million, 15% over $4 million up to and including
$5 million and 18% on adjusted gross gaming proceeds in excess of $5 million.
The Colorado Commission also has imposed an annual device fee of $75 per
gaming device. The Colorado Commission may revise the gaming tax rate and
device fee from time to time. Central City Black Hawk and Cripple Creek each
have imposed annual device fees of approximately $1,000 per gaming device and
may revise the same from time to time.
 
  Colorado has certain unique regulatory laws which, if adversely interpreted
or not modified, may limit or adversely affect the ability of the Company to
enter in, or compete within, the Colorado market. First, as noted,
 
                                      20
<PAGE>
 
gaming in Colorado constitutionally is limited to slot machines, blackjack and
poker. Although no manufacturer or distributor has attempted to distribute the
Company's type of interactive game, it should be included within the
definition of "slot machine." In preliminary discussions, Division personnel
have stated that the device likely is a "slot machine," although neither the
Division nor the Commission have formally ruled on the issue and will not do
so until the product is submitted to the Division for approval.
 
  Second, Colorado constitutionally limits the maximum single bet to $5.00.
Colorado statutes define a bet to be an amount placed as a wager in a game of
chance. If the Company's product permits multiple rounds of betting at $5.00
per round, it would be unclear whether Colorado would permit such betting. If
Colorado does not permit multiple round bets in excess of $5.00, then the
Company would need to adjust its machines to limit the total bets to $5.00,
including all rounds.
 
  Third, Commission Regulations define the requirements of slot machines,
including limitations on the ability to alter the slot machine's program and
the internal requirements of the slot machine itself. The Company's proposed
machines do not comply with existing Regulations. Although the Company intends
to seek a change in the Commission's Regulations, there can be no assurance
that such changes will be made. If the Regulations are not changed, then the
Company will need to modify its machines to conform to Colorado requirements.
Even as so modified, the Company's machines must be approved by the Division
as meeting existing Regulations and there is no assurance that the Company
will receive such approval or will receive such approval in a timely basis.
 
  New Jersey Regulatory Matters. Casino gaming in New Jersey is regulated by
the New Jersey Casino Control Act, N.J.S.A. 5:12-1 et seq., and regulations
promulgated thereunder (the "NJCCA"). The NJCCA created the New Jersey Casino
Control Commission ("NJCCC"), which is authorized to decide all license
applications and other matters and to promulgate regulations, and created the
New Jersey Division of Gaming Enforcement (the "NJDGE"), which is authorized
to investigate all license applications, make recommendations to the NJCCC,
and prosecute violations of the NJCCA. Under the NJCCA, any enterprise
providing goods or services to a casino must register with or be licensed by
the NJCCC. The Company and its wholly-owned subsidiary, Silicon Gaming-New
Jersey, Inc., filed the necessary documents in order to be licensed by the
NJCCC and the NJDGE.
 
  Business enterprises providing goods or services directly related to casino
gaming or simulcast wagering must be licensed as a gaming related Casino
Service Industry ("CSI") prior to conducting business with New Jersey casino
licensees or must have filed a complete application for CSI licensure with the
NJCCC and received the permission of the NJCCC for each business transaction.
 
  A CSI license application consists of a Business Entity Disclosure Form for
the applicant and each of its holding companies and Personal History
Disclosure Forms for each individual required to be found qualified. The
application fee consists of a non-refundable deposit of $5,000 and an
obligation to pay an additional $5,000 if the processing of the application
requires more than 1,000 but less than 2,000 hours and a further $5,000 if the
processing of the application exceeds 2,000 hours. The same fee structure
applies to any renewal application.
 
  In connection with a license application, the NJDGE conducts an
investigation of the Company to determine its suitability for licensure. In
order for the requisite CSI license to be issued by the NJCCC to the Company
and maintained, the Company's officers, directors and key employees and all
beneficial owners of more than five percent (5%) of the Company's Common Stock
must be found qualified by the NJCCC. In order to be found qualified, the
Company, its officers, directors, key employees and five percent (5%)
shareholders must demonstrate by clear and convincing evidence their good
character, honesty and integrity, their financial stability, integrity and
responsibility and their business ability. Any other shareholder or other
person associated with the Company whom the NJCCC deems appropriate, in its
discretion, is also required to be qualified. If a person is required to and
fails to submit to qualification or submits to qualification and is found
disqualified by the NJCCC, the NJCCC may prohibit casinos in New Jersey from
doing business with the Company.
 
 
                                      21
<PAGE>
 
  However, "institutional investors" (as defined in the NJCCC) may be granted
a waiver of the requirement to be found qualified by the NJCCC. An
institutional investor includes any retirement fund administered by a public
agency for the exclusive benefit of federal, state or local public employees,
investment company registered under the Investment Company Act of 1940,
collective investment trust organized by banks under Part Nine of the Rules of
the Comptroller of the Currency, closed end investment trust, chartered or
licensed life insurance company or property and casualty insurance company,
banking and other chartered or licensed lending institution, and investment
advisor registered under The Investment Advisors Act of 1940. At the
discretion of the NJCCC, a waiver of qualification may be granted to such
institutional investors provided the securities are owned for investment
purposes only and the institutional investor certifies that it has no
intention of influencing or affecting the affairs of the issuer or its holding
companies.
 
  After 30 days following the filing of a CSI license application with the
NJCCC, the Company may seek permission from the NJCCC to conduct certain
business transactions with a New Jersey casino. Such "transactional waivers"
will only be granted in the absence of an objection by the NJDGE. Such
approvals are granted for a maximum term of six (6) months subject to renewal.
 
  A CSI license is issued for an initial period of two years and is thereafter
renewable for four year periods. There is no guarantee that the Company will
be granted an initial license or that, following the issuance of an initial
CSI license or any renewal thereof, the Company will continue to be granted
renewals of the license. Additionally, upon application of the NJDGE, the
NJCCC may at any time review any license issued by it and determine to
suspend, revoke or place conditions on such license.
 
  In addition to the required licensure from the NJCCC, the gaming equipment
manufactured, distributed or sold by the Company to New Jersey casinos is
subject to a technical examination by the NJDGE and approval by the NJCCC for,
at a minimum, quality, design, integrity, fairness, honesty and suitability.
The approval process includes the submission of a model of the machine to the
NJDGE for testing, examination and analysis and for comparison with
documentation of the schematics, block diagram, circuit analysis and written
explanation of the method of operation, odds determination and all other
pertinent information. The model remains in the custody of the NJDGE unless
otherwise directed by the NJCCC. All costs of such testing, examination and
analysis are borne by the Company. As part of this approval process, the NJCCC
may require that the manufacturer of any component of the gaming equipment
which the NJCCC, in its discretion, determines is essential to the gaming
operation of the device submit to licensing. Such components would include the
computer control circuitry which causes or allows the device to operate as a
gambling device. The failure or refusal of such a manufacturer to submit to
licensing or the denial of a license by the NJCCC to such manufacturer would
result in the inability of the Company to distribute and market that gambling
device to New Jersey casinos. Prior to a decision by the NJCCC to approve a
particular model of machine, it may require up to 60 days trial period to test
the machine in a licensed casino. During the trial period, the manufacturer or
distributor of the machine shall not be entitled to receive revenue of any
kind whatsoever. Once a model is approved by the NJCCC, all machines of that
model placed in operation in licensed casinos shall operate in conformity with
the model tested by the NJDGE. Any changes in the design, function or
operation of the machine are subject to prior approval by the NJCCC in
consultation with the NJDGE.
 
  Mississippi Regulatory Matters. The manufacture, sale and distribution of
gaming devices for use or play in Mississippi are subject to the Mississippi
Gaming Control Act and the regulations promulgated thereunder (collectively,
the "Mississippi Act"). Such activities are subject to the licensing and
regulatory control of the Mississippi Gaming Commission (the "Mississippi
Commission") and the Mississippi State Tax Commission (collectively referred
to as the "Mississippi Gaming Authorities"). Although not identical, the
Mississippi Act is similar to the Nevada Gaming Control Act and regulations
promulgated thereunder.
 
  On June 20, 1996 the Company was registered by the Mississippi Commission as
a publicly traded corporation (a "Registered Corporation") and the holding
company of Silicon Gaming-Mississippi, Inc. (the "Mississippi Subsidiary").
Also on June 20, 1996 the Mississippi Subsidiary was licensed as a
manufacturer and distributor. SGI and the Mississippi Subsidiary are required
to periodically submit detailed financial and
 
                                      22
<PAGE>
 
operating reports to the Mississippi Commission and furnish any other
information which the Mississippi Commission may require. The Company and the
Mississippi Subsidiary have received the various registrations, approvals,
permits and licenses in order to engage in manufacturing, distribution and
gaming activities as presently conducted in Mississippi. Such licenses,
registrations and approvals are not transferable, are initially issued for a
two-year period and must be renewed periodically thereafter.
 
  Similar to Nevada, the Mississippi Commission may investigate and find
suitable any individual who has a material relationship to, or material
involvement with, the Company or the Mississippi Subsidiary, including record
or beneficial holders of any of the voting securities of the Company, holders
of debt obligations, and officers, directors and employees of the Company and
the Mississippi Subsidiary. The Company and the Mississippi Subsidiary are
required to maintain a current stock ledger in Mississippi which may be
examined by the Mississippi Commission at any time. The Company believes that
all required findings of suitability currently required have been applied for
or obtained. Any applicant for a finding of suitability must pay all
investigative fees and costs of the Mississippi Commission in connection with
such an investigation.
 
  The Mississippi Act requires any person who acquires beneficial ownership of
more than 5% of a Registered Corporation's voting securities to report the
acquisition to the Mississippi Commission and such person may be required to
be found suitable. The Mississippi Act requires that beneficial owners of more
than 10% of a Registered Corporation's voting securities apply to the
Mississippi Commission for a finding of suitability. The Mississippi
Commission has generally exercised its discretion to require a finding of
suitability of any beneficial owner of more than 5% of a Registered
Corporation's Common Stock. Under certain circumstances, an "institutional
investor," as defined by Mississippi Commission policy, which acquires more
than 5%, but not more than 10%, of the Registered Corporation's voting
securities may apply to the Mississippi Commission for a waiver of such
finding of suitability if such institutional investor holds the voting
securities for investment purposes only.
 
  The Company may not make a public offering of its securities without the
approval of the Mississippi Commission if the securities or proceeds therefrom
are intended to be used to construct, acquire or finance gaming facilities in
Mississippi, or to retire or extend obligations incurred for such purposes.
 
  If it were determined that the Mississippi Act was violated by the
Mississippi Subsidiary, the licenses it holds could be limited, condition,
suspended or revoked, subject to compliance with certain statutory and
regulatory procedures, which action, if taken, could materially adversely
affect the Company's manufacturing and distribution.
 
  Federal Regulation. The Federal Gambling Devices Act of 1962 (the "Federal
Act") makes it unlawful, in general, for a person to manufacture, deliver, or
receive gaming machines, gaming machine type devices and components across
state lines or to operate gaming machines unless that person has first
registered with the Attorney General of the United States. The Company is
required to register and renew its registration annually. The Company has
complied with such registration requirements. In addition, various record
keeping equipment identification requirements are imposed by the Federal Act.
Violation of the Federal Act may result in seizure and forfeiture of the
equipment, as well as other penalties.
 
  Native American Gaming. Gaming on Native American lands, including the terms
and conditions under which gaming equipment can be sold or leased to Native
American tribes, is or may be subject to regulation under the laws of the
tribes, the laws of the host state, the Indian Gaming Regulatory Act of 1988
("IGRA"), which is administered by the National Indian Gaming Commission (the
"NIGC") and the Secretary of the U.S. Department of the Interior (the
"Secretary"), and also may be subject to the provisions of certain statutes
relating to contracts with Native American tribes, which are administered by
the Secretary. As a precondition to gaming involving gaming machines, IGRA
requires that the tribe and the state have entered into a written agreement (a
"tribal-state compact") that specifically authorizes such gaming, and that has
been approved by the Secretary, with notice of such approval published in the
Federal Register. Tribal-state compacts vary from state to state. Many require
that equipment suppliers meet ongoing registration and licensing requirements
of the
 
                                      23
<PAGE>
 
state and/or the tribe and some impose background check requirements on the
officers, directors, and shareholders of gaming equipment suppliers. Under
IGRA, tribes are required to regulate all commercial gaming under ordinances
approved by the NIGC. Such ordinances may impose standards and technical
requirements on gaming hardware and software, and may impose registration,
licensing and background check requirements on gaming equipment suppliers and
their officers, directors, and shareholders.
 
  Application of Future or Additional Regulatory Requirements. In the future,
the Company intends to seek the necessary registrations, licenses, approvals
and findings of suitability for the Company, its product and its personnel in
other U.S. and foreign jurisdictions in which the Company identifies
significant sales potential for its product. However, there can be no
assurance that such registrations, licenses, approvals or findings of
suitability will be obtained and will not be revoked, suspended or conditioned
or that the Company will be able to obtain the necessary approvals for its
future products as they are developed in a timely manner, or at all. If a
registration, license, approval or finding of suitability is required by a
regulatory authority and the Company fails to seek or does not receive the
necessary registration, license, approval or finding of suitability, the
Company may be prohibited from selling its product for use in the respective
jurisdiction or may be required to sell its product through other licensed
entities at a reduced profit to the Company.
 
ITEM 2: PROPERTIES
 
  In February 1996, the Company moved from its facilities in Saratoga,
California to a 28,000 square foot leased facility in Palo Alto, California
consisting of 17,000 square feet of office space and 11,000 square feet of
manufacturing space. The lease expires in January 2006. In September 1996, the
Company occupied a 12,000 square foot office building designated primarily for
its sales and support organization in Las Vegas, Nevada. The lease expires in
October 1997. In January 1997, the Company executed a lease for an additional
29,000 square foot manufacturing facility in Mountain View, California
commencing in March 1997 and expiring in February 2006. Also in January 1997,
the Company entered into leases for up to 4,000 square feet of office space
for sales and support in Reno, Nevada.
 
  In connection with the Company's occupancy of the Mountain View
manufacturing site, the 11,000 square feet in Palo Alto previously allocated
to manufacturing will be converted to office space. The Company believes that
its existing manufacturing facility is adequate to meet its production
requirements through 1998.

auditors' report on the Company's financial statements containing an adverse
opinion or disclaimer of opinion or that was qualified or modified as to
uncertainty, audit scope or accounting principles. During such period, there
were no disagreements with Coopers on any matter of accounting principle or
practice, financial statement disclosure or auditing scope or procedure, which
disagreements, if not resolved to Coopers' satisfaction, would have caused it
to make reference to the subject matter of the disagreements in connection
with its report. Further, during this period, there were no events of the type

ARTICLE 2  PREMISES

  2.01  Leased Premises: Lessor leases to Lessee and Lessee rents from Lessor
the premises (herein the "Premises"), containing the rental area set forth in
Section 1.01b of the Basic Lease Terms. The Premises are located at the building
identified in the Basic Lease Terms (which together with underlying real
property is called herein the "Building"), and is a portion of the project
including other buildings described in Section 1.02a of the Basic Lease Terms
(herein the "Center"). The premises and the Center are indicated on a site plan
attached hereto as Exhibit "A". If, upon completion of the space plans for the
Premises, Lessor's architect or space planner determines that the rentable
square footage of the Premises differs from that set forth in the Basic Lease
Terms, then Lessor shall so notify Lessee, and the Base Rent (as shown in
Section 1.04 of the Basic Lease Terms) shall be promptly adjusted in proportion
to the change in square footage. Within ten (10) days following Lessor's
request, the parties shall memorialize the adjustments by executing a
certificate to this Lease prepared by Lessor, provided that the failure or
refusal by Lease prepared by either party to execute the amendment shall not
affect its validity. The form of such certificate is attached as Exhibit "B".

  2.02  Delivery and Acceptance of Premises: Lessor shall deliver the Premises
to Lessee clean and free of debris, on the Commencement Date (unless Lessee is
already in possession), and Lessor further warrants to Lessee that the Common
Facilities referred to in Article 6, plumbing, healing, air conditioning,
ventilating, electrical, lighting facilities and equipment with the Premises,
fixtures, walls (interior and exterior), foundations, ceilings, roofs, floors,
windows, access doors, loading doors, plate glass and skylights shall be in good
operating condition on the Commencement Date. In the event that it is determined
that this warranty has been violated, then it shall be the obligation of the
Lessor, after receipt of written notice from Lessee setting forth with
specificity the nature of the violation, to promptly, at Lessor's sole cost,
rectify such violation. Lessee's failure to give such written notice to Lessor
within six (6) months after the Commencement Date shall cause the conclusive
presumption that Lessor has complied with all of Lessor's obligations hereunder.
The warranty contained in this Section shall be of no force or effect if prior
to the date of This Lease Lessee was the owner or occupant of the Premises.

     Except as otherwise provided in this Lease, Lessee hereby accepts the
Premises in their condition existing as of the Commencement Date or the date
that Lessee takes possession of the Premises, whichever is earlier, subject to
all applicable zoning, municipal, county and state laws, ordinances and
regulations governing and regulating the use of the Premises and any covenants
or restrictions of record, and accepts this Lease subject thereto and to all
matters disclosed thereby and by any exhibits attached hereto. Lessee
acknowledges that neither Lessor nor Lessor's agent has made any representation
or warranty as to the present or future suitability of the Premises for the
conduct of Lessee's business.

  2.03  Building Name and Address: Lessee shall not utilize any name selected by
Lessor from time to time for the Building and/or the Center as any part of
Lessee's corporate or trade name. Lessor shall have the right to change the
name, number or designation of the Building without notice or liability' to
Lessee.

ARTICLE 3  TERM

  3.01  General: the term shall be for the period shown in Section 1.03b of the
Basic Lease Terms. Subject to the provisions of Section 3.03, the term shall
commence on the commencement date (herein "Commencement Date") on the earliest
of (a) the Estimated Commencement Date as set forth in Section 1.03a of the
Basic Lease Terms, or (b) the date Lessee acquires possession or commences use
of the Premises for any purpose other than construction. Within ten (10) days
after possession of the Premises is tendered to Lessee, the parties shall
execute the Exhibit "B" Certificate form provided by Lessor, which shall state
the Commencement Date and the expiration date ("Expiration Date") of the Lease.
Lessee's failure to execute that form shall not affect the validity of Lessor's
determination of those dates.

  3.02  Tender of Possession by Lessor: the premises shall be deemed ready for
occupancy upon the tendered date, but only if and when Lessor, to the extent
applicable, (a) has provided reasonable access to the Premises for Lessee so
that it may be used without unnecessary interference, (b) has substantially
completed all the work required to be done by Lessor in this Lease, and (c) has
obtained requisite governmental approvals to Lessee's occupancy.

  3.03  Delay in Possession: Notwithstanding the provisions of Section 3.01, if
Lessor, for any reason whatsoever, cannot deliver possession of the Premises to
Lessee on/or before the Estimated Commencement Date, this Lease shall not be
void or voidable nor shall Lessor be liable to Lessee for any resulting loss or
damage. However, Lessee shall not be liable for any rent and the Commencement
Date shall not occur until Lessor delivers possession of the Premises and the
Premises are in fact ready for occupancy in accordance with Section 3.02; except
that if Lessor's failure to so deliver possession on the Estimated Commencement
Date is attributable to any action or inaction by Lessee (including any tenant
improvement construction change orders requested by Lessee or Lessee's failure
to supply any information required from Lessee or the furnishing by Lessee of
inaccurate or erroneous estimates, specifications, data or other information),
then the Commencement Date shall not be advanced to the date on which possession
of the Premises is tendered to Lessee, and Lessor shall be entitled to full
performance by Lessee (including the payment of rent) from the Estimated
Commencement Date.

  3.04  Early Occupancy: if Lessee occupies the Premises prior to the Estimated
Commencement Date, Lessee's occupancy of the Premises shall be subject to all of
the provisions of this Lease. Early occupancy of the Premises shall not advance
the expiration date of this Lease. Lessee shall pay Base Rent and all other
charges specified in this Lease for the early occupancy period.

  3.05  Option Term(s): Lessor is hereby granted the right and option to extend
this Lease for the additional term or terms as provided in Section 1 .03c
(herein "Option Term" or "Option Terms") commencing at the expiration of the
initial Term. Such option is granted upon the following terms and conditions:


                                       2                            Initial____

months and no later than six (6) months prior to the expiration of the term
immediately preceding the Option Term(s) to be exercised, time being of the
essence. If said notification is not given and received, the option to be
exercised shall automatically expire. Failure to exercise the first option shall
result in automatic expiration of the second if one so exists.

computed as provided in Section 4.05 below.

shall deposit with Lessor the sum stated in Section 1.05 of the Basic Lease
Terms, to secure the faithful performance of Lessee's obligations hereunder. If

which Lessor may suffer thereby. If Lessor so uses or applies all or any portion
of said deposit, Lessee shall, within ten (10) days after written demand
therefor, deposit cash with Lessor in an amount sufficient to restore said
deposit to the full amount hereinabove stated and Lessee's failure to do so
shall be a material breach of this Lease. If the Base monthly rent shall, from
time to time, increase during the Term, Lessee shall thereupon deposit with

to Lessee (or, at Lessor's option, to the last assignee, if any, of Lessee's
interest hereunder) at the expiration of the Term hereof, and after Lessee has
vacated the Premises. No trust relationship is created herein between Lessor and
Lessee with respect to said security deposit. in no event may Lessee
unilaterally apply or credit its deposit against the last month's rent. Should
Lessor sell its interest in the Premises during the Term hereof and if Lessor
deposits with the Purchaser thereof, the then unappropriated funds deposited by
Lessee as aforesaid, thereupon Lessor shall be discharged from any further
liability with respect to such deposit.

  4.05  Option Rent:

        a.  In the event Lessee duly exercises its option to extend this Lease
as provided in Section 3.05 above, the rent payable during the Option Term(s)
shall be computed and payable as follows: commencing on the first (1st) day of
the Option Term and upon the expiration of each twelve (12) calendar months
thereafter during such Option Term, that portion of the rent constituting the
Base Rent shall be adjusted by multiplying the rent as referenced in Section
1.04a by. a fraction, which fraction shall have as its numerator the Consumer
Price Index For All Urban Consumers using the U.S. City Average (or alternative
thereto as hereinafter provided) is maintained (Base Period 1982-84 = 100), as
published by the U.S. Department of Labor, Bureau of Labor Statistics for the
calendar month, which is four (4) months prior to the)e applicable adjustment
date, and which such fraction shall have as its denominator said Consumer Price
Index, as published for the calendar month which is four (4) months prior to the
commencement of the Initial Term. If the present base of said Index should
hereafter be changed, then the new base shall be converted to the base now used.
in the event that said Bureau: should cease to publish said index figure, then
any similar Index published by any other branch or department of


                                       4                            Initial____

<PAGE>
 
the U.S. Government shall be used. In the event that said Bureau shall publish
more than one such index, then the index showing the greater proportionate
increase shall be sued, and if none is so published, then another index
generally recognized as authoritative shall be substituted by agreement the
parties hereto, or if no such agreement is reached within a reasonable time,
either party may make application to any court of competent jurisdiction to
designate such other index. In any event, the base used by any new index shall
be reconciled to the 1982-84 = 100 base index. In no event shall the Base Rent
to be paid by Lessee pursuant hereto be less than the rent set forth in Section
1.04a or the Base Rent for the twelve (12) month period immediately preceding
the adjustment date, whichever is the greater. In the event the numerator of
said fraction is not available at the time of adjustment of the rent as provided
herein, Lessee shall continue to pay the rent established for the next prior
twelve (12) month period; provided, however, Lessee shall promptly pay to Lessor
any deficiency at such time as said rent is adjusted.

proportion that the floor area of the Premises that is rendered unusable by the
damage from time to time bears to the total floor area of the Premises.

        d.  Notwithstanding the provisions of subsections "a", "b" and "c" of
this Section, the cost of any repairs shall be borne by Lessee, and Lessee shall
not be entitled to rental abatement or termination rights if the damage is due
to the fault or neglect of Lessee or its employees, subtenants, invitees or
representatives. In addition, the provisions of this Section shall not be deemed
to require Lessor to repair any improvements or fixtures that Lessee is
obligated to repair or insure pursuant to any other provisions of this Lease.

ARTICLE 13  EMINENT DOMAIN

  13.01 Total or Partial Taking: if all or a material portion of the Premises is
taken by any lawful authority by exercise of the right of eminent domain, or
sold to prevent a taking, either Lessee or Lessor may terminate this Lease
effective as of the date possession is required to be surrendered to the
authority. In the event title to a portion of the Building or Center, other than
the Premises, is taken or sold in lieu of taking, and if Lessor elects to
restore the Building in such a way as to alter the Premises materially, Lessor
may terminate this Lease, by written notice to Lessee, effective on the date of
vesting of title. In the event neither party has elected to terminate this Lease
as provided above, then Lessor shall promptly, after receipt of a sufficient
condemnation award, proceed to restore the premises to substantially their
condition prior to the taking, and a proportionate allowance shall be made to
Lessee for the rent corresponding to the time during which, and to the part of
the Premises of which, Lessee is deprived on account of the taking and
restoration. In the event of a taking, Lessor shall be entitled to the entire
amount of the condemnation award without deduction for any estate or interest of
Lessee; provided that nothing in this Section shall be deemed to give Lessor any
interest in, or prevent Lessee from seeking any award against the taking
authority for, the taking of personal property and fixtures belonging to Lessee
or for relocation or business interruption expenses recoverable from the taking
authority.

  13.02   Temporary Taking: No temporary taking of the Premises shall terminate
this Lease or give Lessee any right to abatement of rent, and any award
specifically attributable to a temporary taking of the Premises shall belong
entirely to Lessee. A temporary taking shall be deemed to be a taking of the use
or occupancy of the Premises for a period not to exceed ninety (90) days.

  13.03   Taking of Parking Area: in the event there shall be a taking of the
Parking Area such that Lessor can no longer provide sufficient parking to comply
with this tease, Lessor may substitute reasonably equivalent parking in a
location reasonably close to the Building; provided that if Lessor fails to make
that substitution within ninety (90) days following the taking and if the taking
materially Impairs Lessee's use and enjoyment of the Premises, Lessee may, at
its option, terminate this Lease by notice to Lessor. If this Lease is not so
terminated by Lessee, there shall be no abatement of rent and this Lease shall
continue in effect.

ARTICLE 14  SUBORDINATION; ESTOPPEL CERTIFICATE

  14.01     Subordination:

            a.  At the option of Lessor, this Lease shall be either superior or
subordinate to all ground or underlying teases, mortgages, deeds of trust and
conditions, covenants and restrictions, reciprocal easements and rights of way,
if any, which may hereafter affect the Premises or Center, and to all renewals,
modifications, consolidations, replacements


                                      10                            Initial____

and extensions thereof; provided, that so long as Lessee is not in default under
this Lease, this Lease shall not be terminated or Lessee's quiet enjoyment of
the Premises is disturbed in the event of termination of any such ground or
underlying lease, or the foreclosure of any such mortgage or deed of trust, to
which Lessee has subordinated this Lease pursuant to this Section. In the event
of a termination or foreclosure, Lessee shall become a tenant of and attorney to
the successor-in-interest to Lessor upon the same terms and conditions as are
contained in this Lease, and shall execute any instrument reasonably required by
Lessor's successor for that purpose. Lessee shall also, upon written request of
Lessor, execute and deliver all instruments as may be required from time to time
to subordinate the rights of Lessee under this Lease to any ground or underlying
lease or to the lien of any mortgage or deed of trust, or if requested by
Lessor, to subordinate, in whole or in part, any ground or underlying lease or
the heir of any mortgage or deed of trust to this Lease.

     b.  Failure of Lessee to execute any statements or instruments necessary or
desirable to effectuate the provisions of this Article  within ten (10) days
after written request by Lessor, shall constitute a default under this Lease. In
that event, Lessor, in addition to any other rights or remedies it might have,
shall have the right, by written notice to Lessee, to terminate this Lease as of
a date not less than twenty (20) days after the date of Lessor's notice.
Lessor's election to terminate shall not relieve Lessee of any liability for its
default.

  14.02 Estoppel Certificate:

        a.  Lessee shall, at any time not less than twenty (20) days' prior
written notice from Lessor, execute, acknowledge and deliver to Lessor, in any
form that Lessor may reasonably require, a statement, in writing (i) certifying
that this Lease is unmodified and in full force and effect (or, if modified,
slating the nature of the modification and certifying that this Lease is
unmodified and in full force and effect) and the dates to which the rental,
additional rent and other charges have been paid in advance, if any, and (ii)
acknowledging that, to Lessee's knowledge, there are no uncured defaults on the
part of Lessor, or specifying each default if any are claimed, and (iii) setting
forth all further information that Lessor may reasonably require. Lessee's
statement may be relied upon by any prospective purchaser or encumbrancer of all
or any portion of the Building or Center.

        b.  Lessee's failure to deliver any estoppel statement Within the
provided time shall be conclusive upon Lessee that (i) this Lease is in full
force and effect without modification except as may be represented by Lessor,
(ii) there are no uncured defaults in Lessor's performance, and (iii) not more
than one month's rental has been paid in advance.

ARTICLE 15  DEFAULTS AND REMEDIES

  15.01 Lessee's Defaults: In addition to any other event of default set for in
this Lease, the occurrence of any one or more of the following events shall
constitute a default by Lessee:

        a.  the abandonment of the Premises by Lessee. Abandonment is defined to
include, but not limited to, any absence by Lessee from the Premises for ten
(10) days or longer.

        b.  the failure by Lessee to make any payment of rent or additional rent
required to be made by Lessee, as and when due, where the failure continues for
a period of three (3) days after written notice from Lessor to Lessee. For
purposes of these default and remedies provisions, the term "additional rent"
shall be deemed to include all amounts of any type whatsoever, other than Base
Rent, to be paid by Lessee pursuant to the terms of this Lease.

        c.  Assignment, sublease, encumbrance or other transfer of the Lease by
Lessee, either voluntarily or by operation of law, whether by judgment,
execution transfer by intestacy or testacy, or other means, without the prior
written consent of Lessor.

        d.  the discovery by Lessor that any financial statement provided by
Lessee, or by any affiliate, successor or guarantor of Lessee was materially
false.

        e.  the failure or inability by Lessee to observe or perform any of the
express or implied covenants or provisions of this Lease to be observed or
performed by Lessee, other than as specified in any other subsection of this
Section, where the failure continues for a period of thirty (30) days after
written notice from Lessor to Lessee. However, if the nature of the failure is
such that more than thirty (30) days are reasonably required for its cure, then
Lessee shall not be deemed to be in default if Lessee commences the cure within
thirty (30) days and thereafter diligently pursues the cure to completion.

        f.  (i) the making by Lessee of any general assignment for the benefit
of creditors; (ii) the filing by or against Lessee of a petition to have Lessee
adjudged a Chapter 7 debtor under the Bankruptcy Code or to have debts
discharged or a petition for reorganization or arrangement under any law
relating to bankruptcy (unless, in the case of a petition filed against Lessee,
the same is dismissed within sixty (60) days); (iii) the appointment of a
trustee or receiver to take possession of substantially all of Lessee's assets
located at the Premises or of Lessee's interest in this Lease, if possession is
not restored to Lessee within thirty (30) days; (iv) the attachment, execution
or other judicial Seizure of substantially all of Lessee's assets located at the
Premises or of Lessee's interest in this Lease where the seizure is not
discharged within thirty (30) days; or (v) Lessee's convening of a meeting of
its creditors for the purpose of effecting a moratorium upon or composition of
its debts. Lessor shall not be deemed to have knowledge of any event described
in this subsection unless notification in writing is received by Lessor, nor
shall there be any presumption attributable to Lessor of Lessee's insolvency. In
the event that any provision of this subsection is contrary to applicable law,
the prevision shall be of no force or effect.

  15.02 Lessor's Remedies: On the occurrence of any material default by Lessee,
Lessor may, at any time thereafter, with or without notice or demand and without
limiting Lessor in the exercise of any right or remedy which Lessor may have:


                                      11                            Initial____

<PAGE>
 
        a.  Terminate Lessee's right to possession of the Premises by any lawful
means, in which case this Lease shall terminate and Lessee shall immediately
surrender possession of the premises to Lessor. In such event, Lessor shall be
entitled to recover from Lessee all damages incurred by Lessor by reason of
Lessee's default, including (i) the worth at the time of the award of the unpaid
Base Rent, additional rent and other charges which had been earned at the time
of the termination; (ii) the worth at the time of the award of the amount by
which the unpaid Base Rent, additional rent and other charges which would have
been earned after termination until the time of the award exceeds the amount of
such rental loss that Lessee proves could have been reasonably avoided; (iii)
the worth at the time of the award of the amount by which the unpaid Base Rent,
additional rent and other charges which would have been paid for by the balance
of the term after the time of award exceeds the amount of such rental loss that
Lessee proves could have been reasonably avoided; and (iv) any other amount
necessary to compensate Lessor for all the detriment proximately caused by
Lessee's failure to perform its obligations under the Lease or which in the
ordinary course of things would be likely to result therefrom, including, but
not limited to, any costs or expenses incurred by Lessor in maintaining or
preserving the Premises after such default, the cost of recovering possession of
the Premises, expenses of reletting, including necessary renovation or
alteration of the Premises, Lessor's reasonable attorneys' fees incurred in
connection therewith, and any real estate commission paid or payable. As used in
subparts "(i)" and "(ii)" above, the "worth at the time of the award' is
computed by allowing interest on unpaid amounts at the rate of fifteen percent
(15%) per annum, or such lesser amount as may be then the maximum lawful rate.
As used in subpart "(iii)' above, the "worth at the time of the award' is
computing by discounting such amount at the discount rate of the Federal Reserve
Bank of San Francisco at the time of the award, plus one percent (1%). If Lessee
shall have abandoned the Premises, Lessor shall have the option of (i) retaking
possession of the Premises and recovering from Lessee the amount specified in
this Section 15.02a, or (ii) proceeding under Section 1 5.02b.

        b.  Maintain Lessee's right to possession, in which case this Lease
shall continue in effect whether or not Lessee shall have abandoned the
Premises. In such event, Lessor shall be entitled to enforce all of Lessor's
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

        c.  Pursue any other remedy now or hereafter available to Lessor under
the laws or judicial decisions of the state in which the Property is located.

  15.03  Repayment of "Free" Rent: if this Lease provides for a postponement of
any monthly rental payments, a period of "free" rent, or other rent concession,
such postponed rent or "free" rent is called the "Abated Rent". Lessee shall be
credited with having paid all of the Abated Rent on the expiration of the Lease
Term only if Lessee has fully, faithfully and punctually performed all of
Lessee's obligations hereunder, including the payment of all rent (other than
Abated Rent) and all other monetary obligations and the surrender of the
property in the physical condition required by this Lease. Lessee acknowledges
that us right to receive credit for the Abated Rent is absolutely conditioned
upon Lessee's full, faithful and punctual performance of is obligations under
this Lease. If Lessee defaults and does not cure within any applicable grace
period, the Abated Rent shall immediately become due and payable in full and
this Lease shall be enforced as if there were no such rent abatement or other
rent concession. In such case, Abated Rent shall be calculated based on the full
initial rent payable under this Lease.

  15.04  Cumulative remedies: Lessor's exercise of any right or remedy shall not
prevent it from exercising any other right or remedy.

  15.05  Late Payments: Any rent due under this Lease that is not paid to Lessor
within ten (10) days of the date when due shall bear interest at the maximum
rate permitted by law from the date due until fully paid. The payment of
interest shall not cure any default by Lessee under this Lease. In addition,
Lessee acknowledges that the late payment by Lessee to Lessor, of rent, will
cause Lessor to incur costs not contemplated by this Lease, the exact amount of
which will be extremely difficult and impractical to ascertain. Those costs may
include, but are not limited to, administrative, processing and accounting
charges, and late charges which may be imposed on Lessor by the terms of any
ground lease, mortgage or trust deed covering the Premises. Accordingly, if any
rent due from Lessee shall not be received by Lessor or Lessor's designee within
ten (10) days after the date due, then Lessee shall pay to Lessor, in addition
to the interest provided above, a late charge in the amount of ten percent (10%)
of each delinquent payment. Acceptance of a late charge by Lessor shall not
constitute a waiver of Lessee's default with respect to the overdue amount, nor
shall it prevent Lessor from exercising any of its other rights and remedies.

  15.06  Right of Lessor to Perform: All covenants and agreements to be
performed by Lessee under this Lease shall be performed at Lessee's sole cost
and expense and without any abatement of rent or Right of set off. If Lessee
fails to pay any sum of money, other than rent, or fails to perform any other
act on its part to be performed under this Lease, and the failure continues
beyond any applicable grace period set forth in Section 15.01, then in addition
to any other available remedies, Lessor may, at its election, make the payment
or perform the other act on Lessee's part. Lessor's election to make the payment
or perform the act on Lessee's part shall not give rise to any responsibility of
Lessor to continue making the same or similar payments or performing the same or
similar acts. Lessee shall, promptly upon demand by Lessor, reimburse Lessor for
all sums paid by Lessor and all necessary incidental costs, together with
interest at the maximum rate permitted by law from the date of the payment by
Lessor. Lessor shall have the same rights and remedies if Lessee fails to pay
those amounts as lessor would have in the event of a default by Lessee in the
payment of rent.

  15.07  Default by Lessor: Lessor shall no be deemed to be in default in the
performance of any obligation under this Lease unless, and until, it has failed
to perform the obligation within thirty (30) days after written notice by Lessee
to Lessor specifying in reasonable detail the nature and extent of the failure;
provided, however, that if the nature of Lessor's obligation is such that more
than thirty (30) days are required for its performance, then Lessor shall not be
deemed to be in default if it commences performance within the thirty (30) day
period and thereafter diligently pursues the cure to completion.



                                      12                            Initial____

<PAGE>
 
  15.08  Expenses and Legal Fees: Lessee shall reimburse Lessor upon demand, for
any costs or expenses, incurred by Lessor in connection with any breach or
default of Lessee under this Lease, whether or not suit is commenced or judgment
entered. Such costs shall include legal fees and costs incurred for the
negotiation of a settlement, enforcement of rights or otherwise. Furthermore, if
any action for breach of, or 10 enforce, the provisions of this Lease is
commenced, the court in such action shall award to the party in whose favor a
judgment is entered. a reasonable sum as attorneys' fees and costs. Such
attorneys' fees and costs shall be paid by the losing party in such action.
Lessee shall also indemnity Lessor against and hold lessor harmless from all
costs, expenses. demands and liability incurred by Lessor if Lessor becomes or
is made a party to any claim or and/or (a) instituted by Lessee, or by any third
party against Lessee. or by or against any person holding any interest under or
using the Premises by license of or agreement with Lessee; (b) for foreclosure
for any lien for labor or material furnished to or for Lessee or such other
person; (c) otherwise arising out of or resulting from any act or transaction of
Lessee or such other person; or (d) necessary to protect Lessor's interest under
this Lease in a bankruptcy proceeding. or other proceeding under Title 11 of the
United Slates Code, as amended. Lessee shall defend Lessor against any such
claim or action at Lessee's expense with counsel reasonably acceptable to lessor
or, at Lessee's election, Lessee shall reimburse Lessor for any legal fees or
costs incurred by Lessor in any such claim or action.

ARTICLE 16   END OF TERM

  16.01 Holding Over: This Lease shall terminate without further notice upon the
expiration of the Term (herein "Expiration Date"), and any Holding over by
Lessee after the expiration shall not constitute a renewal or extension of this
Lease, or give Lessee any rights under this Lease, except when in writing,
signed by both parties. If Lessee holds over for any period after the expiration
(or earlier termination) of the Term, Lessor may, at its option. treat Lessee as
a tenant at sufferance only, commencing on the first (1st) day following the
termination of this Lease and subject to all of the terms of this Lease. except
that the monthly rental shall be one hundred twenty percent (120%) of the
greater of (a) the total monthly rental for the month immediately preceding the
date of termination, or (b) the then currently scheduled rent for comparable

expiration of this Lease despite demand to do so by Lessor, Lessee shall
indemnify and hold Lessor harmless from all loss or liability, including,
without limitation, any claims made by any succeeding tenant relating to such
failure to surrender. Acceptance by Lessor of rent after the termination shall
not constitute a consent to a holdover or result in a renewal of this Lease. The
foregoing provisions of this Section are in addition to, and do not effect,
Lessor's right of re-entry or any other rights of Lessor under this Lease or at
law.

  16.02 Merger on Termination: the voluntary or other surrender of this Lease by
Lessee, or mutual termination of this Lease, shall terminate any or all existing

Landlord at the office of the Building or at such other place as Landlord
designates:

i.        Base rent ("Base Rent") to be paid in monthly installments in the
amounts set forth in Item 4 of the Schedule, in advance on or before the first
                     ------

Adjustment Rent due for such calendar year, as shown in said statement,  minus
any payments of estimated Adjustment Rent made by Tenant for such year. If
Tenant's estimated payments of Adjustment Rent exceed the amount due Landlord
for such calendar year, Landlord shall apply such excess as a credit against
Tenant's other obligations under this Lease, unless the Term has expired and
Tenant is not in default hereunder, in which case such amount shall be refunded
to Tenant promptly after determination of said overpayment. In no case shall any
overpayment by Tenant earn interest.

months thereafter.  Rent shall be determined based on the increase in the CPI

due until the date paid at the annual rate of ten percent (10%)  from the date
the payment was due (or the first business day thereafter), which rate shall not
exceed the maximum rate permitted by law (the "Default Rate"); and, in addition,
in recognition of the fact that Landlord will incur certain administration costs
and other damages, the amount of which are not readily quantifiable, but of
which the Late Charge (as defined herein) shall be an approximation, Tenant
shall, in addition to interest at the Default Rate, pay Landlord a late charge
for any Rent payment which is paid more than five (5) days after its due date
equal to five percent (5%) of such payment (the "Late Charge");  iv.  Tenant
shall have the right to inspect Landlord's accounting records relative to
Expenses and Taxes during normal business hours at any time within ninety (90)

statement within such ninety (90) day period, such statement shall be considered
as final and accepted by Tenant; v.  in the event of the termination of this
Lease prior to the determination of any Adjustment Rent , Tenant's agreement to
pay any such sums and Landlord's obligation to refund any such sums (provided
Tenant is not in default hereunder) shall survive the termination of this Lease;
vi.  no adjustment to the Rent by virtue of the operation of the rent adjustment
provisions in this Lease shall result in the payment by Tenant in any year of
less than the Base Rent shown on the Schedule;  vii. Landlord may at any time
change the fiscal year of the Building; viii.  each amount owed to Landlord
under this Lease for which the date of payment is not expressly fixed shall be
due on the same date as the Rent listed on the statement showing such amount is
due; and ix. if Landlord fails to give Tenant an estimate of Adjustment Rent
prior to the beginning of any calendar year, Tenant shall continue to pay
Adjustment Rent  at the rate for the previous calendar year until Landlord
delivers such estimate, at which time Tenant shall pay retroactively the
increased amount for all previous months of such calendar year.

term of this Lease occurring after the expiration of any period during which

9.        ALTERATIONS

a.        Requirements. Tenant shall not make any replacement, alteration,
          -------------                                                   
improvement or addition to or removal from the Premises (collectively an
"Alteration") that shall either (a) cost in excess of $10,000 or (b) affect a
Building system, or the Building structure or external appearance without the
prior written consent of Landlord, which consent shall not be unreasonably
withheld unless such Alteration affects the structure or systems of the Building
or affects the exterior appearance of the Building.   Alterations permitted
hereunder without the consent of Landlord will be referred to as "Permitted
Alterations." In the event Tenant proposes to make any Alteration that is not a
Permitted Alteration,  Tenant shall, prior to commencing such Alteration, submit
to Landlord for prior written approval: i.  detailed plans and specifications;
ii. the names, addresses and copies of contracts for all contractors (other than
subcontractors who shall supply materials or services costing less than $5000 in
connection with said work); iii.  all necessary permits evidencing compliance
with all applicable governmental rules, regulations and requirements; iv.
certificates of insurance in form and amounts required by Landlord, naming
Landlord, its managing agent, and any other parties designated by Landlord as
additional insureds; and v.  all other documents and information as Landlord may
reasonably request in connection with such Alteration. Tenant agrees to pay
Landlord's reasonable charges for review of all such items and supervision of
the Alteration.  Neither approval of the plans and specifications nor
supervision of the Alteration by Landlord shall constitute a representation or
warranty by Landlord as to the accuracy, adequacy, sufficiency or propriety of
such plans and specifications or the quality of workmanship or the compliance of
such Alteration with applicable law. Tenant shall pay the entire cost of the
Alteration and, if requested by Landlord, shall deposit with Landlord, prior to
the commencement of the Alteration, security for the payment and completion of
the Alteration in form and amount reasonably required by Landlord.  Each
Alteration shall be performed in a good and workmanlike manner, in accordance
with the plans and specifications approved by Landlord, and shall meet or exceed
the standards for construction and quality of materials reasonably established
by Landlord for the Building. In addition, each Alteration shall be performed in
compliance with all applicable governmental laws and regulations and insurance
company requirements.  Each Alteration that is not a Permitted Alteration shall
be performed under Landlord's supervision, and in harmony with Landlord's
employees, contractors and other tenants. Each Alteration, whether temporary or
permanent in character, made by Landlord or Tenant in or upon the Premises
(excepting only Tenant's furniture, equipment and trade fixtures) shall become
Landlord's property and shall remain upon the Premises at the expiration or
termination of this Lease without compensation to Tenant; provided, however,
that Landlord shall have the right to require Tenant to remove such Alteration
at Tenant's sole cost and expense in accordance with the provisions of Section
14 of this Lease, which required removal shall be specified by Landlord when
Landlord consents to Tenant's requested Alterations.

b.        Liens.  Upon completion of any alteration, Tenant shall promptly
          ------                                                          
furnish Landlord with sworn owner's and contractors' statements and full and
final waivers of lien covering all labor and materials included in such
alteration.  Tenant shall not permit any mechanic's lien to be filed against the
Building, or any part thereof, arising out of any alteration performed, or
alleged to have been performed, by or on behalf of Tenant. If any such lien is
filed, Tenant shall within ten (10) days thereafter have such lien 

                                       11
<PAGE>
 
released of record or diligently contest and deliver to Landlord a bond in form,
amount, and issued by a surety satisfactory to Landlord, indemnifying Landlord
against all costs and liabilities resulting from such lien and the foreclosure
or attempted foreclosure thereof. If Tenant fails to have such lien so released
or to contest and deliver such bond to Landlord, Landlord, without investigating
the validity of such lien, may pay or discharge the same; and Tenant shall
reimburse Landlord upon demand for the amount so paid by Landlord, including
Landlord's expenses and attorneys' fees.

c.        Americans With Disabilities Act.  Replacements, alterations,
          --------------------------------                            
improvements or additions to or removals from the Premises required to achieve
compliance with the Americans With Disabilities Act ("ADA") shall be completed
at Tenant's expense in accordance with the procedures set forth in paragraphs 9
A. and B. of this Lease. Landlord shall be responsible for the cost of any
improvements required by the ADA to be made to the Building or Common Areas, to
the extent any such requirement does not relate to Tenant's particular use of
the Premises, but would be required for any tenant of the Building.


10.       INSURANCE AND INDEMNIFICATION

In consideration of the leasing of the Premises at the Rent stated herein,
Landlord and Tenant agree to provide insurance and allocate the risks of loss as
follows:

a.        Tenant's Insurance. Tenant, at its sole cost and expense but for the
          -------------------                                                 
mutual benefit of itself and Landlord, agrees to purchase and keep in force and
effect during the Term hereof, insurance which is available at commercially
reasonable rates and otherwise commonly carried by tenants in the area, under
policies issued by insurers licensed to do business in the state in which the
Building is located with a Best's rating of A-, class VIII or higher on all
alterations, additions, and improvements owned by Tenant, and on all personal
property located in the Premises, protecting Landlord and Tenant from damage or
other loss caused by perils covered under an All Risk Property Policy, and
Boiler and Machinery Policy, in amounts not less than the full insurable
replacement value of such property. Such insurance shall provide that it is
specific and not contributory and shall name the Landlord and its management
agent as additional insureds and shall contain an agreed amount endorsement.
Such insurance shall also contain a clause pursuant to which the insurance
carriers waive all rights of subrogation against the Landlord with respect to
losses payable under such policies.

Tenant also agrees to maintain commercial general liability insurance covering
Tenant as the insured party, and naming Landlord and its managing agent as an
additional insured, against claims for bodily injury and death and property
damage occurring in or about the Premises, with limits of not less then Two
Million Dollars ($2,000,000.00) per occurrence and Five Million Dollars
($5,000,000.00) general aggregate.

Tenant shall, prior to commencement of the Term, furnish to Landlord
certificates evidencing such coverage, which certificates shall state that such
insurance coverage may not be changed or canceled without at least thirty (30)
days prior written notice to Landlord and Tenant.  In the event Tenant shall
fail to procure such insurance, Landlord may at its option, after giving Tenant
no less than fourteen (14) days prior written notice of its election to do so,
procure the same for the account of Tenant and the cost thereof shall be paid to
Landlord as additional Rent upon receipt by Tenant of bills therefor.  When used
in this Section 10. A the term "Landlord" shall include Landlord's partners,
beneficiaries, officers, agents, servants and employees and the term "Tenant"
shall include Tenant's partners, beneficiaries, officers, agents, servants and
employees.

b.        Landlord's Insurance.  Landlord agrees to purchase and keep in force
          ---------------------                                               
and effect commercial general liability insurance in an amount not less than
Three Million Dollars ($3,000,000.00) per occurrence and Five Million Dollars
($5,000,000.00) general aggregate, and All Risk property insurance with an
agreed amount endorsement, on the Building and Common Areas, insuring 100% of
replacement value (subject to customary deductibles in the market area of the
property on policies maintained by commercial landlords of properties similar to
the Premises and Project), subject to the reimbursement of the full amount
thereof as Expenses.  Notwithstanding the foregoing, during the time that
Prudential shall own the Premises and Project, Prudential's insurance program
maintained for its equity or separate account properties shall be deemed to
satisfy the foregoing.   Subject to the foregoing sentence, such insurance shall
provide that it is specific and not contributory and shall contain a clause
pursuant to which the 

                                       12
<PAGE>
 
insurance carriers waive all rights of subrogation against the Tenant with
respect to losses payable under such policies.


c.        Risk of Loss.  By this Section 10, Landlord and Tenant intend that the
          -------------                                                         
risk of loss or damage as described above be borne by responsible insurance
carriers to the extent above provided, and Landlord and Tenant hereby agree to
look solely to, and to seek recovery only from, their respective insurance
carriers in the event of a loss of a type described above to the extent that
such coverage is agreed to be provided hereunder.  For this purpose, any
applicable deductible amount shall be treated as though it were recoverable
under such policies.  Landlord and Tenant agree that applicable portions of all
monies collected from such insurance shall be used toward the full compliance
with the obligations of Landlord and Tenant under this Lease in connection with
damage resulting from fire or other casualty.  This Paragraph 10.c shall
                                                    --------------      
supersede any provision of this Lease that shall allocate liability for an
insured event to Landlord or Tenant.

d.        Indemnification of Landlord.  Tenant shall indemnify and defend
          ---------------------------                                    
Landlord, its employees and agents and save them harmless from and against any
and all loss and against all claims, actions, damages, liability and expenses,
in connection with loss of life, bodily and personal injury, or property damage
arising from any occurrence in, upon or at the Premises or any part thereof, or
occasioned wholly or in part by any act or omission of Tenant, its agents,
contractors, employees or invitees or by anyone permitted to be on the Premises
by Tenant, except to the extent caused by the negligence or willful misconduct
of Landlord, its employees or agents.  In case Landlord, its employees or agents
shall be made a party to any litigation commenced by or against Tenant, then
Tenant shall indemnify, defend and hold them harmless and shall pay all costs,
expenses, and reasonable attorneys' fees incurred or paid by them in connection
with such litigation.  The obligations assumed herein shall survive the
expiration or sooner termination of this Lease.

11.       FIRE OR OTHER CASUALTY

a.        Destruction of the Building.  If fifty percent (50%) of the area of
          ----------------------------                                       
the Building should be substantially destroyed by fire or other casualty, either
party hereto may, at its option, terminate this Lease by giving written notice
thereof to the other party within thirty (30) days of such casualty.  In such
event, Rent shall be apportioned to and shall cease as of the date of such
casualty. In the event neither party exercises this option, then the Premises
shall be reconstructed and restored as set forth below.

b.        Destruction of the Premises.  If the Premises should be rendered
          ---------------------------                                     
untenantable for the purpose for which they were leased, by fire or other
casualty, but the Building is not substantially destroyed as provided above,
then the parties hereto shall have the following options:

i.    If, in Landlord's reasonable judgment, the Premises cannot be
reconstructed or restored within one hundred eighty (180) days of such casualty
to substantially the same condition as they were prior to such casualty,
Landlord shall so notify Tenant within thirty (30) days of the casualty and
either Landlord or Tenant may elect, within fifteen (15) days thereafter, to
terminate this Lease.   If Tenant makes no election within such fifteen (15) day
period, Landlord shall then have the right, to be exercised within fifteen (15)
days following the expiration of Tenant's election period, by giving written
notice to Tenant, to reconstruct and restore the Premises to substantially the
same condition as they were prior to the casualty.  In such event this Lease
shall continue in full force and effect to the balance of the term, upon the
same terms, conditions and covenants as are contained herein; provided, however,
that the Rent shall be abated in the proportion which the approximate area of
the damaged portion bears to the total area in the Premises from the date of the
casualty until substantial completion (as defined in Exhibit B) of the
                                                     ---------        
reconstruction of the Premises.  If Landlord fails to exercise such right, this
Lease shall be terminated as of the date of the casualty, to which date Rent
shall be apportioned and shall thereafter cease.

Notwithstanding the above, if the casualty occurs during the last twelve (12)
months of the Term of this Lease, either party hereto shall have the right to
terminate this Lease as of the date of the casualty, which right shall be
exercised by written notice to be given by either party to the other party
within thirty (30) days therefrom. If this right is exercised, Rent shall be
apportioned to and shall cease as of the date of the casualty.  If a casualty
occurs during the last twelve (12) months of the term of the Lease, Tenant may
not exercise any extension options without first obtaining Landlord's written
consent.

ii.    If, in Landlord's reasonable judgment, the Premises are able to be
restored within one hundred eighty (180) days to substantially the same
condition as they were prior to such casualty, Landlord shall so notify 

                                       13
<PAGE>
 
Tenant within fifteen (15) days of the casualty, and Landlord shall then proceed
to reconstruct and restore the damaged portion of the Premises, at Landlord's
expense, to substantially the same condition as it was prior to the casualty;
Rent shall be abated in the proportion which the approximate area of the damaged
portion bears to the total area in the Premises from the date of the casualty
until substantial completion (as defined in Exhibit B) of the reconstruction
                                            ---------
repairs, and this Lease shall continue in full force and effect for the balance
of the Term.

iii.      In the event Landlord undertakes reconstruction or restoration of the
Premises pursuant to subparagraph (i) or (ii) above, Landlord shall use
reasonable diligence in completing such reconstruction repairs, but in the event
Landlord fails to substantially complete the same within two hundred forty (240)
days from the date of the casualty, except as a result of any of the occurrences
set forth in subparagraph 25 (j) below, Tenant may, at its option, terminate
this Lease upon giving Landlord written notice to that effect, whereupon both
parties shall be released from all further obligations and liability hereunder.

12.       CONDEMNATION

If the Premises or the Building is rendered untenantable by reason of a
condemnation (or by a deed given in lieu thereof), then either party may
terminate this Lease by giving written notice of termination to the other party
within thirty (30) days after such condemnation, in which event this Lease shall
terminate effective as of the date that possession of such property is required
to be delivered to the condemning authority.  If this Lease so terminates, Rent
shall be paid through and apportioned as of the date of such condemnation.  If
such condemnation does not render the Premises or the Building untenantable, or
if such condemnation affects the Common Areas but not the Premises, and after
such condemnation Landlord shall have sufficient Common Areas in the Project to
enable it to meet all of its obligations to tenants of the Project, including
Tenant, this Lease shall continue in effect and Landlord shall promptly restore
the portion not condemned to the extent reasonably possible to the condition
existing prior to the condemnation and Tenant shall be entitled to an abatement
of Rent based on the extent of Tenant's impairment of the use of its Premises.
In such event, however, Landlord shall not be required to expend an amount in
excess of the proceeds received by Landlord from the condemning authority.
Landlord reserves all rights to compensation for any condemnation, except for
such amount the condemning authority attributes to the value of Tenant's
leasehold interest in the Premises and relocation expenses, but only to the
extent that any such award to Tenant does not reduce the amount payable to
Landlord on account of such condemnation.   Tenant hereby assigns to Landlord
any right Tenant may have to such compensation, and Tenant shall make no claim
against Landlord or the condemning authority for compensation for termination of
Tenant's leasehold interest under this Lease or interference with Tenant's
business.


13.       ASSIGNMENT AND SUBLETTING

a.        Landlord's Consent.  Tenant shall not, without the prior written
          -------------------                                             
consent of Landlord, which shall not be unreasonably withheld:  i.  assign,
convey, mortgage or otherwise transfer this Lease or any interest hereunder, or
sublease the Premises, or any part thereof, whether voluntarily or by operation
of law; or ii. permit the use of the Premises by any person other than Tenant
and its employees.  Any such transfer, sublease or use described in the
preceding sentence (a "Transfer") occurring without the prior written consent of
Landlord shall be void and of no effect.  Landlord's consent to any Transfer
shall not constitute a waiver of Landlord's right to withhold its consent to any
future Transfer.  Landlord's consent to any Transfer or acceptance of rent from
any party other than Tenant shall not release Tenant from any covenant or
obligation under this Lease.  Landlord may require as a condition to its consent
to any assignment of this Lease that the assignee execute an instrument in which
such assignee assumes the obligations of Tenant hereunder.  For the purposes of
this paragraph, however, the transfer (whether direct or indirect) of all or a
majority of the capital stock in a corporate Tenant (other than the shares of
the capital stock of a corporate Tenant whose stock is publicly traded) or the
merger, consolidation or reorganization of such Tenant and the transfer of all
or any general partnership interest in any partnership Tenant shall not be
considered a Transfer, so long as the transferee of the Lease or any successor
or surviving entity shall have a net worth not less than the net worth of Tenant
as of the date of this Lease and shall otherwise agree in writing to be bound by
this Lease.

b.        Standards for Consent.  If Tenant desires the consent of Landlord to a
          ----------------------                                                
Transfer, Tenant shall submit to Landlord, at least twenty (20) days prior to
the proposed effective date of the Transfer, a written notice which includes
such information as Landlord may reasonably require about the proposed Transfer

                                       14
<PAGE>
 
and the transferee, together with a non-refundable processing fee in the amount
of five hundred dollars ($500.00).  Tenant shall also pay all reasonable
attorneys' or other fees and expenses incurred by Landlord in connection with
any proposed Transfer, whether or not Landlord consents to such Transfer.
Landlord's consent or lack thereof shall be provided within twenty (20) days of
receipt of Tenant's notice.  If Landlord shall not respond within such twenty
(20) day period, it shall be deemed to have consented to the proposed transfer.
Landlord shall not be deemed to have unreasonably withheld its consent if, in
the judgment of Landlord: i.  the transferee is of a character or engaged in a
business which is not in keeping with the standards or criteria used by Landlord
in leasing the Building; ii. the financial condition of the transferee is such
that it may not be able to perform its obligations in connection with this
Lease; iii.  the transferee is a tenant of or negotiating for space in the
Building; iv. the transferee is a governmental unit; v. Tenant is in Default
under this Lease; or vi. in the judgment of Landlord, such a Transfer would
violate any term, condition, covenant, or agreement of the Landlord involving
the Building or any other tenant's lease within it.  If Landlord wrongfully
withholds its consent to any Transfer, Tenant's sole and exclusive remedy
therefor shall be to seek specific performance of Landlord's obligation to
consent to such Transfer.

c.        Recapture.    If Landlord consents to any Transfer, Tenant shall pay
          ----------                                                          
to Landlord fifty percent (50%) of all rent and other consideration received by
Tenant in excess of the Rent paid by Tenant hereunder for the portion of the
Premises so transferred. Such rent shall be paid as and when received by Tenant.
Tenant shall have the right to deduct from such excess rent, on a pro-rata
basis, Tenant's reasonable costs and expenses directly related to the Transfer
including, but not limited to, broker's commissions, tenant improvements, and
legal fees.


14.       SURRENDER

Upon expiration or sooner termination of the Term or Tenant's right to
possession of the Premises, Tenant shall return the Premises to Landlord in
substantially the same order and condition when received, except for, ordinary
wear and damage by fire or other casualty or any other damage that Tenant has no
obligation to repair.   Tenant shall remove any of the initial improvements
required to be removed pursuant to Exhibit B hereof, at its sole costs and
                                   ---------                              
expense, prior to the surrender of the Premises, and restore any areas damaged
by such removal to a reasonably good condition consistent with the required
condition of the balance of the Premises under this paragraph.  If Landlord
requires Tenant to remove any alterations pursuant to Section 9, then such
removal shall be done in a good and workmanlike manner; and upon such removal
Tenant shall restore the Premises to its condition prior to the installation of
such alterations. If Tenant does not remove such alterations after request to do
so by Landlord, Landlord may remove the same and restore the Premises; and
Tenant shall pay the cost of such removal and restoration to Landlord upon
demand.  Tenant shall also remove its furniture, equipment, trade fixtures and
all other items of personal property from the Premises prior to termination of
the Term or Tenant's right to possession of the Premises.  If Tenant does not
remove such items, Tenant shall be conclusively presumed to have conveyed the
same to Landlord without further payment or credit by Landlord to Tenant; or at
Landlord's sole option such items shall be deemed abandoned, in which event
Landlord may cause such items to be removed and disposed of at Tenant's expense,
which shall be 115% of Landlord's actual cost of removal, without notice to
Tenant and without obligation to compensate Tenant.


15.       DEFAULTS AND REMEDIES

          a.   Default.  The occurrence of any of the following shall constitute
               --------                                                         
a default (a "Default") by Tenant under this Lease: (i) Tenant fails to pay any
Rent when due, including, without limitation, Adjustment Rent,  and such failure
is not cured within three (3) business days after notice from Landlord (which
notice may be in the form of a statutory notice to pay rent or quit); (ii)
Tenant fails to perform any other provision of this Lease and such failure is
not cured within thirty (30) days (or immediately if the failure involves a
hazardous condition) after notice from Landlord (unless the nature of the
default is such that it cannot reasonably be cured in thirty (30) days, in which
event Tenant shall not be in Default so long as Tenant commences the cure within
thirty (30) days and thereafter diligently prosecute the cure to completion);
(iii) the leasehold interest of Tenant is levied upon or attached under process
of law; (iv) Tenant abandons the Premises; or (v) any voluntary or involuntary
proceedings are filed by or against Tenant or any guarantor of this Lease under
any bankruptcy, insolvency or similar laws and, in the case of any involuntary
proceedings, are not dismissed within thirty (30) days after any filing by
Tenant or sixty (60) days after any involuntary filing.

                                       15
<PAGE>
 
          b.   Remedies Upon Tenant's Default.  Upon a Default, Landlord shall
               -------------------------------                                
have the following remedies, in addition to all other rights and remedies
provided by law, equity, statute or otherwise provided in this Lease, to which
Landlord may resort cumulatively or in the alternative:

Landlord may continue this Lease in full force and effect, and this Lease shall
continue in full force and effect as long as Landlord does not terminate
Tenant's right to possession, and Landlord shall have the right to collect Rent
when due.  During the period Tenant is in default, Landlord may enter the
Premises and relet it, or any part of it, to third parties for Tenant's account,
provided that any Rent in excess of the Rent due hereunder shall be payable to
Landlord, but shall be applied to Tenant's obligations hereunder.  Tenant shall
be liable immediately to Landlord for all costs Landlord incurs in reletting the
Premises, including, without limitation, brokers' commissions, expenses of
cleaning and redecorating the Premises required by the reletting and like costs.
Reletting may be for a period shorter or longer than the remaining Term of this
Lease.  Tenant shall pay to Landlord the Rent and other sums due under this
Lease on the dates the Rent is due, less the Rent and other sums Landlord
receives from any reletting.  No act by Landlord allowed by this Section 15.b
                                                                 ------------
shall terminate this Lease unless Landlord notifies Tenant in writing that
Landlord elects to terminate this Lease.

     "THE LESSOR HAS THE REMEDY DESCRIBED IN CIVIL CODE SECTION 1951.4
     (LESSOR MAY CONTINUE THE LEASE IN EFFECT AFTER LESSEE'S BREACH OR
     ABANDONMENT AND RECOVER RENT AS IT BECOMES DUE, IF LESSEE HAS THE RIGHT TO
     SUBLET OR ASSIGN SUBJECT ONLY TO REASONABLE LIMITATIONS)."

Landlord may terminate Tenant's right to possession of the Premises at any time
by giving written notice to that effect.  No act by Landlord other than giving
written notice to Tenant shall terminate this Lease.  Acts of maintenance,
efforts to relet the Premises or the appointment of a receiver on Landlord's
initiative to protect Landlord's interest under this Lease shall not constitute
a termination of Tenant's right to possession.  On termination, Landlord shall
have the right to remove all personal property of Tenant and store it at
Tenant's cost and to recover from Tenant as damages: (1) the worth at the time
of award of unpaid Rent and other sums due and payable which had been earned at
the time of termination; plus (2) the worth at the time of award of the amount
by which the unpaid Rent and other sums due and payable which would have been
payable after termination until the time of award exceeds the amount of the Rent
loss that Tenant proves could have been reasonably avoided; plus (3) the worth
at the time of award of the amount by which the unpaid Rent and other sums due
and payable for the balance of the Term after the time of award exceeds the
amount of the Rent loss that Tenant proves could be reasonably avoided; plus (4)
any other amount necessary to compensate Landlord for all the detriment
proximately caused by Tenant's failure to perform Tenant's obligations under
this Lease, or which, in the ordinary course of things, would be likely to
result therefrom, including, without limitation, any costs or expenses incurred
by Landlord: (a) in retaking possession of the Premises, including reasonable
attorneys' fees and costs therefor; (b) maintaining or preserving the Premises
for reletting to a new tenant, including repairs or alterations to the Premises
for the reletting; (c) leasing commissions attributable to the new lease; (d)
any other costs necessary or appropriate to relet the Premises; and (e) at
Landlord's election, such other amounts in addition to or in lieu of the
foregoing as may be permitted from time to time by the laws of the State of
California.

The "worth at the time of award" of the amounts referred to in Sections 15.b (1)
                                                               -----------------
and (2) is computed by allowing interest at the lesser of twelve percent (12%)
- -------                                                                       
per annum or the maximum rate permitted by law, on the unpaid Rent and other
sums due and payable from the termination date through the date of award.  The
"worth at the time of award" of the amount referred to in Section 15.b.3 is
                                                          --------------   
computed by discounting the amount at the discount rate of the Federal Reserve
Bank of San Francisco at the time of award, plus one percent (1%).  Tenant
waives redemption or relief from forfeiture under California Code of Civil
Procedure Sections 1174 and 1179, or under any other present or future law, if
Tenant is evicted or Landlord takes possession of the Premises by reason of any
default of Tenant hereunder.

          c.   Other Remedies. Landlord may but shall not be obligated to
               ---------------                                           
perform any obligation of Tenant under this Lease and if Landlord so elects, all
costs and expenses paid by Landlord in performing such obligation, together with
interest at the Default Rate, shall be reimbursed by Tenant to Landlord on
demand. Any and all remedies set forth in this Lease: (i) shall be in addition
to any and all other remedies Landlord may have at law or in equity, (ii) shall
be cumulative, and (iii) may be pursued successively or concurrently as Landlord
may elect. The exercise of any remedy by Landlord shall not be deemed an
election of remedies or preclude Landlord from exercising any other remedies in
the future.

          d.   Bankruptcy. If Tenant becomes bankrupt, the bankruptcy trustee
               -----------                                                   
shall not have the right to assume or assign this Lease unless the trustee
complies with all requirements of the United States Bankruptcy Code; and
Landlord expressly reserves all of its rights, claims, and remedies thereunder.

          e.   Waiver of Trial by Jury. Landlord and Tenant waive trial by jury
               ------------------------                                        
in the event of any action, proceeding or counterclaim brought by either
Landlord or Tenant against the other in connection with this Lease.

          f.   Counterclaims.  Tenant hereby waives the right to interpose any
               --------------                                                 
counterclaim in any proceeding instituted by Landlord against Tenant to
terminate the Lease, to obtain possession of the Premises, or to recover Rent.

          g.   Venue. If either Landlord or Tenant desires to bring an action
               ------                                                        
against the other in connection with this Lease, such action shall be brought in
the federal or state courts located in the state in which the Building in
located.  Landlord and Tenant consent to the jurisdiction of such courts and
waive any right to have such action transferred from such courts on the grounds
of improper venue or inconvenient forum.


16.       HOLDING OVER

If Tenant retains possession of the Premises after the expiration or termination
of the Term or Tenant's right to possession of the Premises, Tenant shall pay
Rent during such holding over at one hundred fifty percent (150%) the rate in
effect immediately preceding such holding over computed on a monthly basis for
each month or partial month that Tenant remains in possession. Tenant shall also
pay, indemnify and defend Landlord from and against all claims and damages,
consequential as well as direct, sustained by reason of Tenant's holding over.
The provisions of this Section do not waive Landlord's right of re-entry or
right to regain possession by actions at law or in equity or any other rights
hereunder, and any receipt of payment by Landlord shall not be deemed a consent
by Landlord to Tenant's remaining in possession or be construed as creating or
renewing any lease or right of tenancy between Landlord and Tenant.


17.       SECURITY DEPOSIT

          a.   On or before the Commencement Date, Tenant shall deliver to
Landlord cash or a  letter of credit having a term of at least one year (the
"Letter of Credit") in an amount equal to the amounts expended by Landlord for
leasing commissions and the amount reimbursed to Tenant for Tenant Improvements
to be made pursuant to Exhibit B hereto, which amount is estimated by Landlord
                       ---------                                              
to be approximately $196,762.  Any Letter of Credit shall be reduced by 1/5 on
each anniversary of the Commencement Date, provided when the balance shall be
reduced to $34,848 (the "Minimum Balance") or less, Tenant shall deliver cash in
the amount of the Minimum Balance in lieu of the Letter of Credit and the Letter
of Credit shall be returned to Tenant.  If the Letter of Credit is replaced with
cash in excess of the Minimum Balance and the conditions to a reduction of the
security shall have been met, then the amount of cash security shall be reduced
on each anniversary of the Commencement Date to the amount of the Letter of
Credit that would otherwise be required hereunder, and any excess shall be
promptly refunded to Tenant.   While any Letter of Credit is outstanding: 1.
Tenant shall replace the letter of credit at least thirty (30) days before the
due date thereof, and if Tenant does not do so, Landlord shall be entitled to
draw on the Letter of Credit for the full amount thereof and shall hold the
proceeds thereof until applied as provided herein, or until Tenant delivers to
Landlord a substitute Letter of Credit ; 2. the issuing bank and the form of the
Letter of Credit shall be satisfactory to Landlord in its sole discretion; 3. if
Landlord shall transfer the property, Tenant shall, provided Landlord shall
agree as a condition to Tenant's obligation hereunder to replace such Letter of
Credit, to return any superseded Letter of Credit to Tenant, cause its bank to
issue a replacement letter of credit or amendment to any existing Letter of
Credit naming the new owner as beneficiary, and if it fails to do so within ten
(10) business days after Landlord's request therefor, Landlord is authorized to
cash the Letter of Credit and deliver the proceeds thereof to any successor
owner, to be applied as provided herein; and 4) the Letter of Credit shall be
security for Tenant's timely performance of its obligations hereunder, and if a
default shall occur under the Lease, Landlord may cash the Letter of Credit and
apply the proceeds thereof as described in the next succeeding subsection of
this Paragraph.

                                       17
<PAGE>
 
          b.    The Letter of Credit and any cash held by Landlord pursuant to
the preceding subsection of this Paragraph  (the "Security Deposit") shall be
security for the performance of Tenant's obligations under this Lease. Upon the
occurrence of a Default, Landlord may use all or any part of the Security
Deposit for the payment of any Rent or for the payment of any amount which
Landlord may pay or become obligated to pay by reason of such Default, or to
compensate Landlord for any loss or damage which Landlord may suffer by reason
of such Default. If any portion of the Security Deposit is used, Tenant shall
within five (5) business days after written demand therefor deposit cash with
Landlord in an amount sufficient to restore the Security Deposit to its original
amount. Landlord shall not be required to keep the Security Deposit separate
from its general funds, and Tenant shall not be entitled to interest on the
Security Deposit, except to the extent required by law. In no event shall the
Security Deposit be considered an advanced payment of Rent, and in no event
shall Tenant be entitled to use the Security Deposit for the payment of Rent.
The Security Deposit or any balance thereof after applying said security deposit
to the obligations of Tenant under this Lease, shall be returned to Tenant
within thirty (30) days after the expiration of the Term and vacation of the
Premises by Tenant.  Landlord shall have the right to transfer the Security
Deposit to any purchaser of the Building. Upon transfer of the Security Deposit,
Tenant shall look solely to such purchaser for return of the Security Deposit;
and Landlord shall be relieved of any liability with respect to the Security
Deposit.


18.       [INTENTIONALLY DELETED]

19.       ESTOPPEL CERTIFICATE

a.        Tenant shall within ten (10) business days following written request 
by Landlord:

          1.   Execute and deliver to Landlord any documents, including estoppel
          certificates, in the form prepared by Landlord:

               (i)    certifying that this Lease is unmodified and in full force
               and effect or, if modified, stating the nature of such
               modification and certifying that this Lease, as so modified, is
               in full force and effect, and the date to which the rent and
               other charges are paid in advance, if any; and

               (ii) acknowledging that there are not, to Tenant's knowledge, any
               uncured defaults on the part of Landlord hereunder, or if there
               are uncured defaults on the part of the Landlord, stating the
               nature of such uncured defaults; and

               (iii)  evidencing the status of the Lease as may be required
               either by a lender making a loan to Landlord to be secured by
               deed of trust or mortgage covering the Premises or a purchaser of
               the Property from Landlord.

          Tenant's failure to deliver an estoppel certificate within ten
          (10) business days after delivery of Landlord's written request
          therefor shall be conclusive upon Tenant:

               (x)    that this Lease is in full force and effect, without
                      modification except as may be represented by Landlord;

               (y)    that there are then no uncured defaults in Landlord's
                      performance; and

               (z)    that no rent has been paid in advance.


b.        Landlord shall, within twenty (20) days following written request by
Tenant execute and deliver to Tenant an estoppel certificate in a form
reasonably satisfactory to Landlord certifying (i) that this Lease is unmodified
and in full force and effect or, if modified, stating the nature of such
modification, and (ii) acknowledging that there are not, to Landlord's
knowledge, any uncured defaults on the part of Tenant hereunder, or if there are
uncured defaults on the part of the Landlord, stating the nature of such uncured
defaults.

20.       SUBORDINATION

This Lease is and shall be expressly subject and subordinate at all times to (i)
any ground or underlying lease of the Building, now or hereafter existing, and
all amendments, renewals and modifications to any such lease, and (ii) the lien
of any mortgage or trust deed now or hereafter encumbering fee title to the
Building and/or the leasehold estate thereunder, and all amendments, renewals,
modifications and extensions thereof unless such ground lease or ground lessor,
mortgage or mortgagee, or trust deed or trustee or beneficiary, expressly
provides or elects that the Lease shall be superior to such lease, mortgage, or
trust deed.  Without limiting the foregoing, such subordination may be effected
by notice by any ground lessor, mortgagee, trustee or beneficiary to Tenant, or
by a unilateral instrument of subordination executed by such mortgagee, trustee,
or ground lessor and recorded in the records of the county in which the Building
is located, without the necessity of written notice to or further agreement of
Tenant.  If any such mortgage or trust deed is foreclosed, or if any such ground
lease is terminated, upon request of the mortgagee, holder or lessor, as the
case may be and regardless of whether such mortgagee or lessee shall have
subordinated its interest to the interest of Tenant under this Lease, Tenant
will attorn to the purchaser at the foreclosure sale or to the lessor under such
lease, as the case may be on the terms and conditions contained in this Lease,
or shall execute a new lease with such purchaser at the foreclosure sale or to
the lessor under such lease, as the case may be, on all of the terms and
conditions contained in this Lease.  The foregoing provisions are declared to be
self-operative and no further instruments shall be required to effect such
subordination and/or attornment; provided, however, that Tenant agrees upon
request by any such mortgagee, holder, lessor or purchaser at foreclosure, to
execute and deliver such subordination and/or attornment instruments as may be
required by such person to confirm such subordination and/or attornment, or any
other documents required to evidence superiority of the ground lease or
mortgage, should ground lessor or mortgagee elect such superiority, provided it
shall be a condition of Tenant's obligation to execute any such subordination
agreement that the beneficiary of such agreement agree in the same agreement
that in the event of a foreclosure, such beneficiary shall recognize the Lease
and Tenant's right to posses the Premises shall not be disturbed so long as it
shall not be in Default under this Lease.  If Tenant fails to execute and
deliver any instrument or document required under this paragraph, within ten
(10) days after request, Tenant shall be deemed to have irrevocably appointed
Landlord and Landlord's beneficiaries as Tenant's attorneys-in-fact to execute
and deliver such instrument or document in Tenant's name.


21.       QUIET ENJOYMENT

Landlord represents that it has the authority to enter into this Lease.  As long
as no Default exists, Tenant shall peacefully and quietly have and enjoy the
Premises for the Term, free from interference by Landlord, subject, however, to
the provisions of this Lease. The loss or reduction of Tenant's light, air or
view will not be deemed a disturbance of Tenant's occupancy of the Premises nor
will it affect Tenant's obligations under this Lease or create any liability of
Landlord to Tenant.


22.       BROKER

Tenant represents to Landlord that Tenant has dealt only with the broker(s) set
forth in Item 7 of the Schedule (collectively, the "Broker") in connection with
         ------                                                                
this Lease and that, insofar as Tenant knows, no other broker negotiated this
Lease or is entitled to any commission in connection herewith. Tenant agrees to
indemnify, defend and hold Landlord and Landlord's beneficiaries and agents
harmless from and against any claims for a fee or commission made by any broker,
other than the Broker, claiming to have acted on behalf of Tenant in connection
with this Lease. Landlord agrees to pay the Broker a commission in accordance
with a separate agreement between Landlord and the Broker.


23.       NOTICES

All notices and demands to be given by one party to the other party under this
Lease shall be given in writing, mailed or delivered to Landlord or Tenant, as
the case may be, at the address set forth in the Schedule or at such other
address as either party may hereafter designate.  Notices shall be delivered by
hand or by United States certified or registered mail, postage prepaid, return
receipt requested, or by a nationally recognized overnight air courier service.
Notices shall be considered to have been given upon  actual receipt or refusal
of delivery.

          -----------------------                                          
provision of this Lease shall extend to, bind and inure to the benefit of
Landlord and Tenant and their respective legal representatives, successors and
assigns; and all references herein to Landlord and Tenant shall be deemed to
include all such parties.  The term "Landlord" as used in this Lease, so far as
covenants or obligations on the part of Landlord are concerned, shall be limited
to mean only the owner or owners of the Building at the time in question.

b.        Entire Agreement.  This Lease, and the riders and exhibits, if any,
          -----------------                                                  
attached hereto which are hereby made a part of this Lease, represent the
complete agreement between Landlord and Tenant; and Landlord has made no
representations or warranties except as expressly set forth in this Lease. No
modification or amendment of or waiver under this Lease shall be binding upon
Landlord or Tenant unless in writing signed by Landlord and Tenant.

c.        Time of Essence.  Time is of the essence of this Lease and each and
          ----------------                                                   
all of its provisions.

d.        Execution and Delivery. Submission of this instrument for examination
          -----------------------                                              
or signature by Tenant does not constitute a reservation of space or an option
for lease, and it is not effective until execution and delivery by both Landlord
and Tenant. Execution and delivery of this Lease by Tenant to Landlord shall
constitute an irrevocable offer by Tenant to lease the Premises on the terms and
conditions set forth herein, which offer may not be revoked for fifteen (15)
days after such delivery.

e.        Severability. The invalidity or unenforceability of any provision of
          -------------                                                       
this Lease shall not affect or impair any other provisions.

f.        Governing Law. This Lease shall be governed by and construed in
          --------------                                                 
accordance with the laws of the state in which the Building is located.

g.        Attorneys' Fees.  In the event of a litigation arising out of this
          ----------------                                                  
Lease, the prevailing party shall be entitled to be paid all costs and expenses,
including reasonable attorneys' fees, incurred by such party in any such action.

h.        Delay in Possession.  In no event shall Landlord be liable to Tenant
          --------------------                                                
if Landlord is unable to deliver possession of the Premises to Tenant on the
Commencement Date for causes outside Landlord's reasonable control.  If Landlord
is unable to deliver possession of the Premises to Tenant by the Commencement
Date, the Commencement Date shall be deferred until Landlord can deliver
possession to Tenant.  If the Commencement Date is so delayed and as a result
would occur on a day other than the first day of the month; (i) the Commencement
Date shall be further delayed until the first day of the following month, (ii)
Tenant shall be allowed to take occupancy of the Premises prior to the
Commencement Date, subject to all of the terms and conditions of this Lease and
shall pay the pro-rata Rent for such partial month, and (iii) the Expiration
Date shall be extended so that the Term will continue for the full period
contemplated in the Schedule.

i.        Joint and Several Liability.  If Tenant is comprised of more than one
          ----------------------------                                         
party, each such party shall be jointly and severally liable for Tenant's
obligations under this Lease.

j.        Force Majeure. Landlord shall not be in default hereunder and Tenant
          --------------                                                      
shall not be excused from performing any of its obligations hereunder if
Landlord is prevented from performing any of its obligations hereunder due to
any accident, breakage, strike, shortage of materials, acts of God or other
causes beyond Landlord's reasonable control ("Force Majeure").

k.        Captions. The headings and titles in this Lease are for convenience
          ---------                                                          
only and shall have no effect upon the construction or interpretation of this
Lease.

l.        No Waiver. No receipt of money by Landlord from Tenant after
          ----------                                                  
termination of this Lease or after the service of any notice or after the
commencing of any suit or after final judgment for possession of the Premises
shall renew, reinstate, continue or extend the Term or affect any such notice or
suit.  No waiver 

                                       20
<PAGE>
 
of any default of Tenant shall be implied from any omission by Landlord to take
any action on account of such default if such default persists or is repeated,
and no express waiver shall affect any default other than the default specified
in the express waiver and then only for the time and to the extent therein
stated.

m.        Limitation of Liability. Any liability of Landlord under this Lease
          ------------------------                                           
shall be limited solely to its interest in the Project (including sale proceeds,
insurance proceeds and current rents), and in no event shall any personal
liability be asserted against Landlord in connection with this Lease nor shall
any recourse be had to any other property or assets of Landlord.

25.       PARKING

          Tenant shall have the right to park in the Building's parking
facilities in common with other tenants of the Building upon terms and
conditions, including imposition of a reasonable parking charge, as may from
time to time be established by Landlord, provided Tenant shall have at least 109
spaces allocated to it.  Tenant acknowledges that parking is currently on a
first-come, first-served basis.   Tenant agrees not to use in excess of the
number of spaces allocated to it and agrees to cooperate with Landlord and other
tenants in the use of the parking facilities.  Landlord reserves the right, in
its absolute discretion, to determine whether the parking facilities are
becoming crowded and to allocate and assign parking spaces among Tenant and the
other tenants, so long as the number of spaces allocated to Tenant shall not be
reduced unless Landlord is required by law to do so.  Landlord shall not be
liable to Tenant, nor shall this Lease be affected, if any parking is impaired
by moratorium, initiative, referendum, law, ordinance, regulation or order
passed, issued or made by any governmental or quasi-governmental body.

26.       SIGNAGE

          Tenant shall be entitled to a monument sign identifying its Premises
of a size and configuration consistent with the character of the Project and any
other signs in the Project, provided the sign shall be reasonably visible from
Highway 101 and provided further that the final plans relating to any such
monument sign shall be approved by Landlord in its reasonable discretion.

IN WITNESS WHEREOF, the parties hereto have executed this Lease in manner
sufficient to bind them as of the day and year first above written.

and Silicon Gaming, Inc. ("Lease") relating to certain premises ("Premises")
which are more particularly described in Exhibit A of this Lease.  Landlord and
                                         ---------                             
Tenant agree as follows with respect to the Tenant Improvements to be installed
in the Premises:

1.   PLANS AND SPECIFICATIONS.  Plans and specifications and Working Drawings
     ------------------------                                                
     sufficient for the construction of the Tenant Improvements to be installed
     in the Premises (the "Drawings") shall be prepared by Tenant's Architect
     ("Architect") and submitted to Landlord.  Within five (5) business days
     after Drawings have been delivered to Landlord,  Landlord shall reasonably
     approve or disapprove the preliminary plans and specifications, provided
     Landlord shall specify in writing any objections it shall have to the
     Drawings.  If Landlord fails to disapprove the Drawings, within five (5)
     business days after delivery thereof to Landlord, the Drawings shall be
     deemed approved.  If Landlord reasonably disapproves the Drawings,
     Landlord  shall, in its notice of disapproval, provide sufficient
     information to Architect so that revised Drawings can be prepared.  If
     Landlord and Tenant shall disagree on any aspect of the  Drawings, Landlord
     and Tenant will meet and promptly attempt to resolve any differences.
     Architect shall revise the Drawings based on Landlord's suggested changes
     or the changes agreed between Landlord and Tenant, and resubmit the revised
     Drawings until the parties are able to agree on the final form of Drawings.
     The parties will agree on the final form of Drawings within twenty (20)
     business days of the date of Architect's initial submittal, provided in any
     and all events Landlord shall have at least three (3) business days to
     review and respond to the final version of the Drawings.    The working
     drawings and specifications which have been approved by Landlord and Tenant
     are hereinafter referred to as the "Approved Working Drawings."  At the
     time of final approval of the Working Drawings, Landlord shall specify
     which of the improvements shown on the Working Drawings shall be required
     to be removed by Tenant at Tenant's sole costs, upon the expiration of the
     Term and/or surrender of the Premises.

          Construction Contract, including, without limitation, the schedule of
          progress payments and the amount of retention provided therein shall
          be subject to the reasonable approval of Landlord.  The Tenant

     Premises or (c)  the date that Tenant shall commence its business
     operations from Premises. As used herein (and throughout the lease), the
     term "substantial completion" shall mean  the date on which all of the
     following have occurred: (i) the work contemplated has been completed
     substantially in  accordance with the plans and specifications therefor in
     a good and workmanlike  manner and in compliance with applicable laws and
     (ii) a certificate of occupancy or other governmental approval shall have
     been issued which shall permit the legal occupancy of the Premises.  The

     omission of Landlord (wrongful, negligent or otherwise), its employees,
     agents or contractors (including acts or omissions while acting as agent or
     contractor for Tenant).  The term Landlord Delay shall include, but shall
     not be limited to, any of the following, to the extent that such act or
     omission of Landlord actually delays Tenant in the completion of the Tenant
     Improvements:  (i) delay in the giving of authorizations or approvals by
     Landlord beyond any period specified in the Lease; (ii) delay attributable
     to the acts or failure to act, whether willful, negligent or otherwise, of
     Landlord, its agents or contractors, where such acts or failures to act
     delay the completion of the Tenant Improvements; or (iii) delay
     attributable to the interference of Landlord, its agents or contractors
     with the completion of the Tenant Improvements or the failure or refusal of
     any such part to permit Tenant, its agents or contractors,  access to and
     use of the Building or any Building facilities or services, including
     loading docks, which access and use are required for the orderly and
     continuous performance of the work necessary to complete the Tenant
     Improvements.  Tenant shall give Landlord notice within five (5) days after
     the alleged occurrence of a Landlord Delay, which notice shall reasonably
     describe the nature and duration of the Landlord Delay, as a condition to
     the occurrence of a Landlord Delay, or it shall waive any right to assert a
     Landlord Delay.

     ---------

     of the Lease.

                of rent after the date on which it is due. The parties hereby
                agree that such late charge represents a fair and reasonable

                payment by Lessee. Acceptance of such late charge by Lessor
                shall in no event constitute a waiver of Lessee's default with

                by Lessee under this Lease, nor prevent Lessor from excising any

                faithful performance of the terms, conditions, covenants, and
                agreements of this Lease. The security deposit may not be
                applied against rental payments by the Lessee. If the Lessee
                fully complies with all the terms, conditions, covenants and
                agreements of the Lease, then within thirty (30) days after the

                interest shall be refunded to Lessee (or, at Lessor's option at
                the last permitted assignee of Lessee's interests hereunder)
                less the reasonable value of damages suffered by the Lessor,
                including but not limited to rental delinquencies, costs of

                or acts done, which will increase the rate of insurance upon the

                 statement from Lessor's insurance carrier stating that the rate
                 of increase was caused solely by an activity of Lessee on the
                 premises as permitted in this Lease. Any other provision hereof
                 to the contrary notwithstanding, Lessee shall not do or permit

                 occupants of the Building or injure or annoy them or use or
                 allow the premises to be used for any improper, immoral,
                 unlawful or objectionable purpose, nor shall Lessee cause,
                 maintain or permit any nuisance in, on or about the premises.
                 Lessee will not commit or suffer to be committed any waste in

ENTRY BY        15. Lessee shall permit Lessor and its agents to enter the
LESSOR          Demised Premises at all reasonable times for any of the
                following purposes: To inspect same; to show said premises to
                prospective purchasers; to maintain the Building; to make such
                repairs to the Demised Premises as Lessor is obligated or elects
                to make; to make repairs, alterations, additions or utility
                installations to any other portion of the Building; to post

TOTAL           under a standard form of fire and extended coverage policy and
DESTRUCTION     in the event of partial destruction of the Demised Premises
                during the term of this Lease from any cause insured under said
                policy, Lessor shall forthwith repair the same, provided such
                repairs can be made within ninety (90) days from date of such
                destruction, under the then applicable laws and regulations of
                Federal, State, County and Municipal Authorities and in light of
                the extent of such damage and the then condition of the labor
                market and availability of materials and supplies, but such
                partial destruction shall in no way annul or void this Lease,
                except that Lessee shall be entitled to a proportionate
                reduction of rent while such repairs are being made, such
                proportionate reduction to be based upon the extent to which the
                making of such repairs shall interfere with the business carried
                on by Lessee in the Demised Premises. In the event that the
                Building is destroyed to the extent of not less than fifty
                percent (50%) of the replacement cost of the Building, Lessor

                less than two (2) months term remaining on this Lease, than this
                Lease may, at the option of Lessor, be canceled by notice in

                person, WITHOUT THE WRITTEN CONSENT OF LESSOR FIRST HAND AND
                OBTAINED, and a consent td one assignment, subletting, occupancy

                assignment, subletting, occupancy or use. The Lessor may refuse
                its consent without giving any reason whatsoever, and such

DEFAULT         18. If default shall be made in the payment of rent or any
GROUNDS         installment thereof or in the payment of any other amount

                assets and/or this Lease shall be levied on or seized under

                filed by or against Lessee to declare Lessee bankrupt or to
                delay, reduce or modify Lessee's debts or obligations or if any
                petition shall be filed or other action taken to reorganize or
                modify Lessee's capital structure, or if Lessee be declared
                insolvent according to law, or if any assignment of Lessee's
                property shall be made for the benefit of creditors, or if a
                receiver or trustee is appointed for Lessee or its property, or
                if Lessee shall abandon or vacate the Demised Premises during
                the term of this Lease, and thereupon at its option may, without
                notice or demand of any kind to Lessee or any other person, have
                any one or more of the remedies specified in Paragraph 19, in
                addition to all other rights and remedies provided by law or in
                equity.

DEFAULT         19. (a) Lessor may re-enter the Demised Premises with or
REMEDIES        without the process of law and take possession of the same and
                of all equipment and fixtures of Lessee therein and expel or
                remove Lessee and all other parties occupying the Demised
                Premises, using such force as may be reasonably necessary to do
                so, without being liable to any prosecution for such re-entry or
                for the use of such force and without terminating this Lease, at
                any time and from time to time to re-let the Demised Premises or
                any part thereof for the account of Lessee, for such term, upon
                such conditions and at such rental as Lessor may deem proper.
                In such event Lessor may receive and collect rent from such
                re-letting and apply it against any amounts due from Lessee
                hereunder (including without limitation such expenses as Lessor
                may have incurred in recovering possession of the Demised
                Premises, placing same in good order and condition, altering or
                repairing the same for re-letting, and all other expenses,
                commissions, and charges including attorney's fees which
                Lessor may have paid or incurred in connection with such
                repossession and re-letting). Lessor may execute any lease made
                pursuant hereto in Lessor's name or in the name of Lessee as
                Lessor may see fit, and Lessee thereunder shall be under no
                obligation to see to the application by Lessor of any rent
                collected by Lessor nor shall Lessee have any right to collect
                any rent thereunder. Whether or not the Demised Premises are re-
                let, Lessee shall pay Lessor all amounts required to be paid by
                Lessee up to the date of Lessor's re-entry and thereafter Lessee
                shall pay Lessor, until the end of the term hereof, the amount
                of all rent and other charges required to be paid by Lessee
                hereunder, less the proceed of such re-letting during the term
                hereof, if any, after payment of Lessor's expenses as provided
                above. Such payments by Lessee shall be due at such times as are
                provided elsewhere in this Lease, and Lessor need not wait until
                the termination of this Lease to recover them by legal action or
                otherwise Lessor shall not, by any re-entry or other act, be
                deemed to have terminated this Lease or the liability of Lessee
                for the total rent hereunder unless Lessor shall give Lessee
                written notice of Lessor's election to terminate this Lease.

                 (b) Lessor may give written notice to Lessee of Lessor's
                election to terminate this Lease, re-enter the Demised Premises
                with or without process of law and take possession of the same
                and of all equipment and fixtures therein, and expel or remove
                Lessee and all other parties occupying the premises, using such
                force as may be reasonably necessary to do so, without being
                liable to any prosecution for such re-entry of for the use of
                such force. In such event Lessor shall thereupon be entitled to
                recover from Lessee the worth, at the time of such termination,
                of the excess, if any, of the rent and other charges required to
                be paid by Lessee hereunder for the balance of the term hereof

                period.

                (c) Lessee hereby releases, indemnifies, and holds harmless
                Lessor from any liability whatsoever for the removal of persons
                and the removal and storage of property pursuant to
                subparagraphs (a) and (b) of this Paragraph 19.

                (d) To secure the full and timely performance of all the 
                Lessee's obligations under this Lease, Lessee hereby grants to
                Lessor a security interest and lien in all of Lessee's
                equipment, goods, fixtures, furnishings, furniture, inventory,
                machinery, trade fixtures, other property, and the proceeds
                therefrom, now or hereafter to be located within the Demised
                Premises. In the event of default or breach by Lessee, then with
                respect to that security interest, Lessor may exercise all of
                the rights and remedies granted a secure party under the Uniform
                Commercial Code as adopted in Nevada in effect at the time.

                (e) The remedies given to Lessor in this Paragraph 19 shall be
                in addition to and supplemental to all other rights and remedies
                which Lessor may have under the laws then in force.

HOLDING OVER    20. If Lessee holds possession of all or a part of the Demised
                Premises after the expiration of the term of this Lease, with or
                without the express or implied consent of Lessor, Lessee shall
                become a tenant from month-to-month only, upon the terms,
                covenants, conditions, and agreements herein specified, so far
                as applicable. Such holding over shall not constitute an
                extension or renewal of this Lease. During such holding over,
                the Base Monthly Rental shall be increased fifty (50%) percent
                over the Base Monthly Rental provided in Paragraph 2.

WAIVER          21. No covenant, term, condition or agreement or the breach
                thereof shall be deemed waived, except by written consent of the
                party against whom the waiver is claimed, and any waiver or the
                breach of any covenant, term, condition or agreement shall not
                be deemed to be a waiver of any preceding or succeeding breach
                of the same or any other covenant, term, condition or agreement.
                Acceptance by Lessor of any performance by Lessee after the time
                the same shall become due shall not constitute a waiver by
                Lessor of the breach or default of any covenant, term, condition
                or agreement unless other wise expressly agreed to by Lessor in
                writing.

NOTICES         22. Except as otherwise provided in this Lease, all notices or
                demands of any kind required or desired to be given by Lessor to
                Lessee hereunder shall be in writing and shall be deemed
                delivered when hand delivered or forty eight (48) hours after
                depositing the notice or demand in the United States Mail,
                certified or registered, postage prepaid, addressed to the
                Lessee at the Demised Premises, whether or not Lessee has
                departed from, abandoned or vacated the Demised Premises. All

                States Mail, certified or registered, postage prepaid, addressed
                to the Lessor at such address as shall from time to time be
                designated by Lessor to Lessee in writing.

CONDEMNATION    23. In the event any condemnation proceedings shall be commenced
                affecting the Demised Premises, Lessee shall have no right to
                claim any valuation for its leasehold interest or otherwise by

                to use the common area, and Lessee shall not obstruct the
                common areas, including the sidewalks, landscaped areas, paved

LESSOR          Lessor fails to perform obligations required of Lessor within a
                reasonable time, but in no event later than thirty (30) days
                after written notice by Lessee to Lessor, specifying wherein
                Lessor has failed to perform such obligation; provided, however,
                that if the nature of Lessor's obligation is such that more than
                thirty (30) days are required for performance, then Lessor shall
                not be in default if Lessor commences performance within such
                thirty (30) day period and thereafter diligently prosecutes the
                same to completion.

LIABILITY       29. Lessee shall, at Lessee's sole cost and expense, obtain and
                keep in force during the term of this Lease a policy of
                comprehensive public liability insurance insuring Lessor, Lessee
                and Lessor's mortgage against any liability arising out of the
                ownership, use, occupancy or maintenance of the Premises and all
                areas appurtenant thereto. Such insurance shall be in the amount
                of not less than $1,000,000.00 for injury or death of one person
                                 -------------                                  
                in any one accident or occurrence and in the amount of not less
                than $1,000,000.00 for injury or death of more than one person
                     -------------                                            
                in any one accident or occurrence. Such insurance shall further
                insure Lessor and Lessee against liability for property damage
                of at least $500,000.00. The limit of any such insurance shall
                            -----------                                       
                not, however, limit the liability of the Lessee hereunder.
                 Lessee may provide this insurance under a blanket policy,
                provided that said insurance shall have a Lessor's protective
                liability endorsement attached thereto. If Lessee shall fail to
                procure and maintain said insurance, Lessor may, but shall not
                be required to, procure and maintain same, but at the expense of
                Lessee. Insurance required hereunder shall be in companies
                approved by Lessor which approval shall not be unreasonably
                withheld. Lessee shall deliver to Lessor, upon request, copies
                of policies of liability insurance required herein or
                certificates evidencing the existence and amounts of such
                insurance with loss payable clauses satisfactory to Lessor. No
                policy shall be cancelable or subject to reduction of coverage

                deliver to Lessor a statement in writing; (i) certifying that
                this Lease is unmodified in full force and effect, (or if
                modified, state the nature of such modification and certifying
                that this Lease, as so modified, is in full force and effect)
                and the date to which the rent and other charges are paid in
                advance, if any and (ii) acknowledging that there are not, to
                Lessee's knowledge, any uncured defaults on the part of Lessor
                hereunder, or specifying such defaults, if any, are claimed. Any
                such statement may be conclusively relied upon by a prospective
                purchaser or encumbrance of the Demised Premises. Lessee's
                failure to deliver such statement within such time shall be
                conclusive upon Lessee (i) that this Lease is in full force and
                effect, without modification except as may be represented by
                Lessor, (ii) that there are no uncured defaults in Lessor's
                performance, and (iii) that not more than one (1) month's rent
                has been paid in advance. If Lessor desires to finance or
                refinance the Demised Premises, or any part thereof, Lessee
                hereby agrees to deliver to any lender designated by Lessor such
                financial statements of Lessee as may be reasonably required by
                such lender. Such statements shall include the past three (3)
                years financial statements of Lessee. All such financial
                statements shall be received by Lessor in confidence and shall
                be used only for the purposes herein set forth.

COSTS OF SUIT   31. (a) If Lessee or Lessor shall bring any action for any
                relief against the other, declaratory or otherwise, arising out
                of this Lease, including any suit by Lessor for the recovery of
                rent or possession of the Demised Premises, the prevailing party
                is entitled to an award of reasonable attorney's fees which
                shall be deemed to have accrued on the commencement of such
                action and shall be paid whether or not such action is
                prosecuted to judgment.

                party to any litigation instituted by Lessee or by a third
                party against Lessee, or by or against any person holding over

                 DUTIES OWED BY A NEVADA REAL ESTATE LICENSEE

In Nevada, a real estate licensee can (1) act for only one party to a real 
estate transaction, (2) act for more than one party to a real estate transaction
with written consent of each party, (3) act as a broker who assigns different
licensees affiliated with the broker's company to separate parties to a real
estate transaction. A licensee, acting as an agent, must act in one of the above
capacities in every real estate transaction. If this form is used for a lease,
the term Seller shall mean Landlord/Lessor and the term Buyer means
Tenant/Lessee.

LICENSEE:  The licensee in the real estate transactions is Edward G. Yuill

                which said premises are hereby leased; and no use shall be made
                of the Demised Premises, or acts done, which will increase the

                OBTAINED, and a consent to one assignment, subletting, occupancy
                or use, shall not be construed as a consent to any subsequent
                assignment, subletting, occupancy or use. The Lessor may refuse
                its consent without giving any reason whatsoever, and such
                refusal shall nevertheless be binding on Lessee.

DEFAULT         18. If default shall be made in the payment of rent or any
GROUNDS         installment thereof or in the payment of any other amount
                required to be paid by Lessee under this Lease, or any other
                agreement between Lessor and Lessee, or if in default shall be
                made in the performance of any of the other covenants, terms,
                conditions, or agreements which Lessee is required to observe

                filed by or against Lessee to declare Lessee bankrupt or to
                delay, reduce or modify Lessee's debts or obligations or if any
                petition shall be filed or other action taken to reorganize or
                modify Lessee's capital structure, or if Lessee be declared
                insolvent according to law, or if any assignment of Lessee's
                property shall be made for the benefit of creditors, or if a
                receiver or trustee is appointed for Lessee or its property, or
                if Lessee shall abandon or vacate the Demised Premises during
                the term of this Lease, and thereupon at its option may, without
                notice or demand of any kind to Lessee or any other person, have

                addition to all other rights and remedies provided by law or in
                equity.

DEFAULT         19. (a) Lessor may re-enter the Demised Premises with or
REMEDIES        without the process of law and take possession of the same and
                of all equipment and fixtures of Lessee therein and expel or
                remove Lessee and all other parties occupying the Demised
                Premises, using such force as may be reasonably necessary to do
                so, without being liable to any prosecution for such re-entry or
                for the use of such force and without terminating this Lease, at
                any time and from time to time to re-let the Demised Premises or
                any part thereof for the account of Lessee, for such term, upon
                such conditions and at such rental as Lessor may deem proper.
                In such event Lessor may receive and collect the rent from such
                re-letting and apply it against any amounts due from Lessee
                hereunder (including without limitation such expenses as Lessor
                may have incurred in recovering possession of the Demised
                Premises, placing same in good order and condition, altering or
                repairing the same for re-letting, and all other expenses,
                commissions, and charges including attorney's fees which
                Lessor may have paid or incurred in connection with such
                repossession and re-letting). Lessor may execute any lease made
                pursuant hereto in Lessor's name or in the name of Lessee as
                Lessor may see fit, and Lessee thereunder shall be under no
                obligation to see to the application by Lessor of any rent
                collected by Lessor nor shall Lessee have any right to collect
                any rent thereunder. 
                 Whether or not the Demised Premises are re-let, Lessee shall
                pay Lessor all amounts required to be paid by Lessee up to the
                date of Lessor's re-entry and thereafter Lessee shall pay
                Lessor, until the end of the term hereof, the amount of all rent
                and other charges required to be paid by Lessee hereunder, less
                the proceed of such re-letting during the term hereof, if any,
                after payment of Lessor's expenses as provided above. Such
                payments by Lessee shall be due at such times as are provided
                elsewhere in this Lease, and Lessor need not wait until the
                termination of this Lease to recover them by legal action or
                otherwise Lessor shall not, by any re-entry or other act, be

                deemed to have terminated this Lease or the liability of Lessee
                for the total rent hereunder unless Lessor shall give Lessee
                written notice of Lessor's election to terminate this Lease.

                (b) Lessor may give written notice to Lessee of Lessor's
                election to terminate this Lease, re-enter the Demised Premises
                with or without process of law and take possession of the same
                and of all equipment and fixtures therein, and expel or remove
                Lessee and all other parties occupying the premises, using such
                force as may be reasonably necessary to do so, without being
                liable to any prosecution for such re-entry of for the use of
                such force. In such event Lessor shall thereupon be entitled to
                recover from Lessee the worth, at the time of such termination,
                of the excess, if any, of the rent and other charges required to
                be paid by Lessee hereunder for the balance of the term hereof
                (if this lease had not been so terminated) over the then
                reasonable rental value of the Demised Premises for the same
                period.

                (c) Lessee hereby releases, indemnifies, and holds harmless
                Lessor from any liability whatsoever for the removal of persons
                and the removal and storage of property pursuant to
                subparagraphs (a) and (b) of this Paragraph 19.

                (d) To secure the full and timely performance of all the Lessee
                5 obligations under this Lease, Lessee hereby grants to Lessor a
                security interest and lien in all of Lessee's equipment, goods,
                fixtures, furnishings, furniture, inventory, machinery, trade
                fixtures, other property, and the proceeds therefrom, now or
                hereafter to be located within the Demised Premises. In the
                event of default or breach by Lessee, then with respect to that
                security interest, Lessor may exercise all of the rights and
                remedies granted a secure party under the Uniform Commercial
                Code as adopted in Nevada in effect at the time.

                (e) The remedies given to Lessor in this Paragraph 19 shall be
                in addition to and supplemental to all other rights and remedies
                which Lessor may have under the laws then in force.

HOLDING OVER    20. If Lessee holds possession of all or a part of the Demised
                Premises after the expiration of the term of this Lease, with or
                without the express or implied consent of Lessor, Lessee shall
                become a tenant from month-to-month only, upon the terms,
                covenants, conditions, and agreements herein specified, so far
                as applicable. Such holding over shall not constitute an
                extension or renewal of this Lease. During such holding over,
                the Base Monthly Rental shall be increased fifty (50%) percent
                over the Base Monthly Rental provided in Paragraph 2.

WAIVER          21. No covenant, term, condition or agreement or the breach
                thereof shall be deemed waived, except by written consent of the
                party against whom the waiver is claimed, and any waiver or the
                breach of any covenant, term, condition or agreement shall not
                be deemed to be a waiver of any preceding or succeeding breach
                of the same or any other covenant, term, condition or agreement.
                Acceptance by Lessor of any performance by Lessee after the time
                the same shall become due shall not constitute a waiver by
                Lessor of the breach or default of any covenant, term, condition
                or agreement unless other wise expressly agreed to by Lessor in
                writing.

NOTICES         22. Except as otherwise provided in this Lease, all notices or
                demands of any kind required or desired to be given by Lessor to
                Lessee hereunder shall be in writing and shall be deemed

                to the Lessor at such address as shall from time to time be
                designated by Lessor to Lessee in writing.

CONDEMNATION    23. In the event any condemnation proceedings shall be commenced
                affecting the Demised Premises, Lessee shall have no right to
                claim any valuation for its leasehold interest or otherwise by
                reason of its occupancy of or improvements to said premises, and
                any condemnation award (Whether adjudicated or by way of
                settlement) shall belong in its entirety to Lessor. In the event
                of condemnation of a part of the Demised Premises, the rent
                shall be reduced in the proportion that the floor area taken
                bears to the total floor area prior to the taking. If
                condemnation takes more than twenty five percent (25%) of the
                floor area of the Demised Premises or if the amount of Lessee's
                parking area following condemnation is not sufficient to meet
                the deed restrictions, if any, concerning parking on the real
                property on which the Demised Premises are situated, or the
                local parking ordinances, if any, only then, may Lessee, at
                Lessee's option, terminate this Lease as of the date the
                condemning authority takes possession of said condemned portion
                by giving written notice of termination to Lessor within ten
                (10) days after the condemning authority takes such
                possession. 
                 If Lessee does not terminate this Lease as herein above
                immediately provided, then the rent payable shall be reduced as
                set forth above.

SUBORDINATION   24.  This Lease at Lessor's option shall be subject and
                subordinate to the lien of any mortgages or deeds of trust in
                any amount or amounts whatsoever now or hereafter placed on or
                against the real property or improvements, or either thereof, of
                which the Demised Premises are a part, or on or against Lessor's
                interest or estate therein, without the necessity of the
                execution and delivery of any further instruments on the part of
                Lessee to effectuate such subordination. If any mortgage or
                trustee shall elect to have this Lease prior to the lien of its
                mortgage or deed of trust, and shall give written notice thereof
                to Lessee, this Lease shall be deemed prior to such mortgage or
                deed or trust, whether this Lease is dated prior or subsequent
                to the date of said mortgage or deed of trust or the date of the
                recording thereof. Lessee covenants and agrees to execute and
                deliver upon demand, without charge therefore, such further
                instruments evidencing such subordination of this Lease to the
                lien of any such mortgages or deeds of trust as may be required
                by Lessor. Lessee hereby appoints Lessor as Lessee's attorney-
                in-fact, irrevocably, to execute and deliver any such
                agreements, instruments, releases or other documents.

PARKING         25. (a) Lessee and its customers, employees and tradesmen may
                park only operative vehicles on the surfaced parking lot
                adjacent to the Demised Premises only during Lessee's normal
                business hours on terms and conditions as may be established by
                Lessor from time to time during the term of this Lease. The
                parking areas referred to in this Paragraph 25 shall be used on
                a non-exclusive basis with other occupants of the Building. THE
                PARKING LOT MAY NOT BE USED TO STORE VEHICLES OR TO WORK ON
                VEHICLES. NO VEHICLE SHALL BE PARKED IN A PARKING LOT FOR MORE
                THAN TWENTY FOUR (24) CONSECUTIVE HOURS. Any vehicles parked in
                the parking lots in breach of these terms may be towed away at
                Lessee's expense. Lessee releases, indemnifies, and holds
                harmless Lessor and Lessor's officers, employees, and agents
                from any claims arising from or relating to such towing of
                vehicles including any consequential damages or loss of property
                or the use of the vehicle or other. property. The right to tow a
                vehicle is in addition to Lessor's rights under the Lease for
                default or breach of any of the terms hereof.

                (b) Other than parking, egress and ingress, Lessee has no right
                to use the common area, and Lessee shall not obstruct the
                common areas, including the sidewalks, landscaped areas, paved
                areas, parking, lots, or driveways. ANIMALS, INCLUDING
                WATCHDOGS, ARE NOT ALLOWED ON THE DEMISED PREMISES OR COMMON
                AREAS.

                upon and inure to the benefit of the heirs, executors,
                administrators, successors, and assigns of the parties hereto,
                provided that nothing in this paragraph shall be deemed to

                the provisions of Paragraph 17.

                reasonable time, but in no event later than thirty (30) days
                after written notice by Lessee to Lessor, specifying wherein
                Lessor has failed to perform such obligation; provided, however,
                that if the nature of Lessor's obligation is such that more than
                thirty (30) days are required for performance, then Lessor shall
                not be in default if Lessor commences performance within such
                thirty (30) day period and thereafter diligently prosecutes the
                same to completion.

                Lessee may provide this insurance under a blanket policy,
                provided that said insurance shall have a Lessor's protective
                liability endorsement attached thereto. If Lessee shall fail to
                procure and maintain said insurance, Lessor may, but shall not
                be required to, procure and maintain same, but at the expense of
                Lessee. Insurance required hereunder shall be in companies
                approved by Lessor which approval shall not be unreasonably
                withheld. Lessee shall deliver to Lessor, upon request, copies
                of policies of liability insurance required herein or
                certificates evidencing the existence and amounts of such
                insurance with loss payable clauses satisfactory to Lessor. No
                policy shall be cancelable or subject to reduction of coverage
                which Lessor may carry.

ESTOPPEL        30. Lessee shall at any time upon not less than ten (10) days
CERTIFICATE     prior written notice from Lessor execute, acknowledge and
                deliver to Lessor a statement in writing; (i) certifying that
                this Lease is unmodified in full force and effect, (or if
                modified, state the nature of such modification and certifying
                that this Lease, as so modified, is in full force and effect)
                and the date to which the rent and other charges are paid in
                advance, if any and (ii) acknowledging that there are not, to
                Lessee's knowledge, any uncured defaults on the part of Lessor
                hereunder, or specifying such defaults, if any, are claimed. Any
                such statement may be conclusively relied upon by a prospective
                purchaser or encumbrance of the Demised Premises. Lessee's
                failure to deliver such statement within such time shall be
                conclusive upon Lessee (i) that this Lease is in full force and
                effect, without modification except as may be represented by
                Lessor, (ii) that there are no uncured defaults in Lessor's

                 DUTIES OWED BY A NEVADA REAL ESTATE LICENSEE

In Nevada, a real estate licensee can (1) act for only one party to a real 
estate transaction, (2) act for more than one party to a real estate transaction
with written consent of each party, (3) act as a broker who assigns different
licensees affiliated with the broker's company to separate parties to a real
estate transaction. A licensee, acting as an agent, must act in one of the above
capacities in every real estate transaction. If this form is used for a lease,
the term Seller shall mean Landlord/Lessor and the term Buyer means
Tenant/Lessee.

LICENSEE:  The licensee in the real estate transactions is Edward G. Yuill 
                                                           ---------------

    (d)  Any changes in Licensee's relationship to a party to the real estate 
         transaction.
2.  Disclose, if applicable, that Licensee is acting for more than one party to

in chapters 119, 119A, 119B, 645, 645A and 645C of the NRS.

                         (A DEVELOPMENT STAGE COMPANY)

OVERVIEW

THIS DISCUSSION INCLUDES A NUMBER OF FORWARD-LOOKING STATEMENTS WHICH REFLECT
THE COMPANY'S CURRENT VIEWS WITH RESPECT TO FUTURE EVENTS AND FINANCIAL
PERFORMANCE. THESE FORWARD-LOOKING STATEMENTS ARE SUBJECT TO CERTAIN RISKS AND
UNCERTAINTIES, INCLUDING THOSE REFERRED TO IN THE RISK FACTORS SECTION BELOW AND
ELSEWHERE HEREIN AND CONTAINED IN THE COMPANY'S PREVIOUSLY FILED FORM 10 AND
FORM S-1 REGISTRATION STATEMENTS, THAT COULD CAUSE ACTUAL RESULTS TO DIFFER
MATERIALLY FROM HISTORICAL RESULTS OR THOSE ANTICIPATED. IN THIS DISCUSSION, THE
WORDS "ANTICIPATES," "BELIEVES," "EXPECTS," "INTENDS," "FUTURE" AND SIMILAR
EXPRESSIONS IDENTIFY FORWARD-LOOKING STATEMENTS. READERS ARE CAUTIONED NOT TO
PLACE UNDUE RELIANCE ON THESE FORWARD-LOOKING STATEMENTS, WHICH SPEAK ONLY AS OF
THE DATE HEREOF.

The following discussion should be read in conjunction with the audited
consolidated financial statements and notes thereto included in this Annual
Report.

The Company was incorporated on July 27, 1993 to design, develop, manufacture
and distribute interactive gaming devices that implement advanced multimedia
technologies using state-of-the-art, off-the-shelf components. Since its
formation, the Company has been in the development stage, and its principal
activities have consisted of assembling a technical, marketing and executive
staff, developing its gaming platform, raising capital, and initiating
applications for regulatory approvals in Nevada and other jurisdictions to
manufacture and distribute its gaming devices. To date, the Company has
generated no sales or other revenue and has had negative operating cash flows.

The Company's first commercial product was approved for product field testing in
Nevada in December 1996. Following the completion of field testing, the product
was approved for sale to licensed casinos in Nevada by the Nevada Gaming
Commission on March 20, 1997. Accordingly, the Company is now commencing the
next phase in its transition to making commercial sales of its product.
Consistent with industry practice, the Company's product will first be installed
on a trial basis on casino floors for a period of 45 days before a sales
decision is made by the customer. In the fourth quarter of 1996, the Company
commenced manufacture of commercial units and, in 1997, the Company intends to
transition from the development stage to commercial distribution of its product.
The Company plans to limit the number of machines it sells in 1997, however, in
order to carefully monitor reactions to its platform, game software and product
support features. In 1998, the Company expects to broadly market and sell its
product; thus, the Company believes that 1998 will be the first year in which a
reasonable assessment can be made of its product's commercial potential. Future
revenue, profits, and cash flows will depend on market acceptance of the
Company's product, the ability of such product to generate higher revenue for
casinos as compared to competitive products and the technical performance of the
Company's product. The Company's success will also depend on, among other
factors, the Company's ability to attract, retain and motivate qualified
personnel and meet all the initial and ongoing licensing requirements in key
jurisdictions.

Effective April 1, 1995, the Company changed its fiscal year end from March 31
to December 31. Accordingly, the period ended December 31, 1995 is a nine-month
period.

RESULTS OF OPERATIONS

The Company is in the development stage and has not generated any revenue to
date. As of December 31, 1996, the Company had net losses since inception of
$19,614,000. To date, the Company has focused its resources on product
development, including system hardware and software, game concept development
and software coding, hiring additional marketing and administrative staff,
ramping up its marketing activities and starting up the manufacturing
operations. In addition to increasing expenditures in research and development,
the Company will need to incur significant expenses and other costs associated
with the commencement of manufacturing operations and building sales, support
and

                                      27
<PAGE>
 
administrative infrastructure. During 1996, units were manufactured primarily
for testing and engineering, game development, licensing approval and regulatory
field trials. In the fourth quarter of 1996, the Company commenced
manufacture of units for commercial distribution, although volume shipments are
not expected to commence until the second quarter of 1997. The Company did not
generate any product sales or any revenue from other sources in 1996. The
Company's plan for 1997 is to limit the number of machines it sells so that it
can collect feedback from casino operators and gaming patrons before commencing
a full roll-out of its product. Accordingly, the Company expects only limited
revenue in 1997 and expects to incur substantial losses and negative operating
cash flows at least through the second quarter of 1998.

Amounts for the year ended March 31, 1995, the nine-month period ended December
31, 1995, and the year ended December 31, 1996 may not be comparable due to the
Company's change in fiscal year-end. The Company believes that operating
expenses will increase in the future as it continues to develop its product and
emerges from the development stage to begin commercial operations, including
manufacturing, marketing and sales. Accordingly, the Company expects that future
results will differ materially from, and may not be comparable to, prior
periods.


Research and Development
- ------------------------
Research and development ("R&D") expenses include payroll and related costs of
employees engaged in ongoing design and development activities, fees to outside
contractors, early prototype development expenses, overhead costs, equipment
depreciation and costs of supplies. To date, the Company has expensed all costs
associated with the research, design and development of its product. R&D
expenses were $1,539,000, $3,137,000 and $7,030,000 for the year ended March 31,
1995, the nine-month period ended December 31, 1995, and the year ended December
31, 1996, respectively. Increases over the periods have resulted from the
incremental hiring of personnel, increased usage of engineering consultants and
license fees and similar costs associated with the acquisition of outside
technologies. The Company believes that a significant level of R&D expense is
required due to the technical nature of the product and the elaborate
requirements of the game development process. Accordingly, the Company
anticipates devoting substantial resources, including additional personnel, to
R&D and that these costs will continue to increase in absolute dollars in future
periods.

Manufacturing Development
- -------------------------
Manufacturing development expenses include payroll and related costs for
manufacturing personnel, overhead costs, reserves against inventory and
depreciation. In the fourth quarter of 1996, the Company completed initial
development of its manufacturing process and commenced commercial production.
Manufacturing development expenses were $2,458,000 for the year ended December
31, 1996. There were no manufacturing development expenses in prior
periods. Manufacturing expenses are expected to increase through 1997 as the
Company expands its manufacturing capacity and infrastructure to produce its
product in commercial quantities. Upon commencement of sales of its product,
manufacturing costs will be matched to the corresponding revenue or included in
inventory prior to product sale. Due to the significant resources required to
manufacture its product and the early stage of its manufacturing processes, the
Company believes the fixed costs associated with its manufacturing activities
will increase significantly in absolute dollars in future periods.

Selling, General and Administrative
- -----------------------------------
Selling, general and administrative ("SG&A") expenses include payroll and
related costs for administrative and executive personnel and sales and marketing
personnel, overhead costs, legal and associated costs, costs associated with
obtaining corporate and product licenses in various jurisdictions and fees for
professional services. SG&A expenses were $312,000, $922,000 and $5,045,000 for
the year ended March 31, 1995, the nine-month period ended December 31, 1995,
and the year ended December 31, 1996, respectively. Increases over the periods
result from the incremental hiring of personnel and expenses associated with
applying for corporate and product licensing in various jurisdictions. SG&A
expenses are expected to increase substantially in absolute dollars as the
Company invests in sales and marketing activities to launch its product and in
administrative personnel to support its growing infrastructure and comply with
regulatory requirements.

Income Taxes
- ------------
The Company has not been required to pay income taxes due to its net operating
losses in each period since inception. As of December 31, 1996, the Company had
net operating loss carryforwards of approximately $18,600,000 for federal
purposes and $17,200,000 for state purposes. These loss carryforwards will
expire beginning in 2000, if not utilized. The Company also has R&D credit
carryforwards of approximately $490,000 for federal and state purposes as of
December 31, 1996, which expire beginning in 2010. A valuation allowance has
been recorded for these deferred tax assets as a result of uncertainties
regarding the realization of these assets due to the lack of earnings history of
the Company. Due to changes in ownership, as defined by Section 382 of the
Internal Revenue Code, that may have resulted from the sale of Series B and
Series C Redeemable Convertible Preferred Stock in private placements and the
sale of Common Stock in the Company's initial public offering, the annual
deductibility of a substantial portion of the federal net operating loss and tax
credit carryforwards may be limited. See Note 7 of Notes to Consolidated
Financial Statements.

LIQUIDITY AND CAPITAL RESOURCES

To date, the Company has financed its operations primarily through the issuance
of Common Stock in its initial public offering, private placements of Redeemable
Convertible Preferred Stock and loans from shareholders which were subsequently
converted to Redeemable Convertible Preferred Stock. In August 1996, the Company
completed its initial public offering, in which the Company received proceeds,
net of underwriting discounts and offering expenses, of $32,855,000. Through
December 31, 1996, the amounts raised in the private placements of Redeemable
Convertible Preferred Stock, net of issuance costs, totaled $22,943,000. As of
December 31, 1996, the Company had $35,266,000 of cash and cash equivalents and
short-term investments to fund operations.

The Company's operating activities used cash of $1,696,000, $3,731,000 and
$11,991,000 for the year ended March 31, 1995, the nine-month period ended
December 31, 1995 and the year ended December 31, 1996, respectively. Cash used
in operating activities primarily reflects net losses, partially offset by
depreciation and amortization and changes to working capital.

From inception through December 31, 1996, the Company acquired a total of
$3,930,000 in fixed assets, primarily computer equipment, of which $1.0 million
was financed under a capital lease.

In the future, the Company expects to significantly increase cash used in
operating activities in order to commence commercial production and distribution
of its product, enhance manufacturing capabilities, expand sales and support
operations, increase research and development activities and add administrative
infrastructure. The Company believes that its cash on hand will be sufficient to
meet its anticipated cash needs for working capital, capital expenditures and
business expansion. However, the Company may need to raise additional funds to
finance more rapid expansion, to develop its product, to respond to competitive
pressures or to acquire complementary products, businesses or technologies. No
assurance can be given that additional financing will be available or that, if
available, it will be available on terms acceptable to the Company or its
shareholders. If adequate funds are not available to satisfy either the short-
term or long-term capital requirements, the Company may be required to limit its
operations significantly. The Company's capital requirements will depend on many
factors, including, but not limited to, the rate at which the Company can
introduce its product, the market acceptance and competitive position of such
product, the response of competitors to the Company's product, and the ability
of the Company to satisfy the licensing requirements in various jurisdictions
applicable to the Company, its product, and in some jurisdictions, its officers,
directors, employees or principal shareholders.

                                      29

RISK FACTORS

SINGLE PRODUCT; RISK OF TECHNICAL ERRORS; UNCERTAIN MARKET ACCEPTANCE. The
Company's success will depend on the success of a single product. There can be
no assurance that a substantial technical difficulty with, or an undetected
error in, the Company's software or hardware will not arise, possibly resulting
in unanticipated costs, production delays, temporary revocation of existing
product licenses or delays in future product licensing.

To achieve commercial success, the Company's gaming platform must be accepted
both by casino operators and by gaming patrons. Because acceptance of the
platform by casino operators will ultimately depend on win per machine, the
Company believes that its ultimate success will depend on player acceptance. The
Company has performed only limited market studies to support its belief that its
platform design will be perceived by slot players as an improvement in slot
machine design, and there can be no assurance that its gaming platform will be
accepted by casino patrons. Player preferences are highly subjective, vary
substantially among geographic and demographic markets and are subject to
unpredictable change. Because the Company's gaming platform contains features
not found on traditional slot machines, it may not appeal to the player for whom
familiarity and predictability are an important consideration. As a new and
relatively small entrant in a market dominated by larger companies, the Company
believes that its success will require that its gaming platform demonstrate
superior, as opposed to merely comparable, win per machine when compared to
traditional slot machines and other gaming platforms offered by more established
competitors. The Company also believes its product must have superior
performance since its price is expected to exceed that of its competitors'
products. Although several casinos have agreed to install and evaluate the
Company's gaming platform, any purchases of gaming platforms by such casinos, or
by others that may conduct similar evaluations in the future, will likely
require that the Company's machine outperform competing machines on the casino
floor. If the Company's gaming platform does not perform well in its initial
evaluations, the Company's business, financial condition and results of
operations will be materially and adversely affected, and investors will be
exposed to the risk of loss of at least a portion of their investment.

REGULATORY APPROVAL.  The Company will be required to obtain the necessary
licenses, approvals, findings of suitability and product approvals in all
jurisdictions in which it intends to distribute its product. The licensing and
approval processes can involve extensive investigation into the Company and its
officers, directors, employees, principal shareholders and product, and can
require significant expenditures of time and resources by the Company. The
Company and certain of its subsidiaries have been approved as manufacturers and
distributors of gaming devices in Nevada, Mississippi, Missouri and Colorado.
The Company has also applied for the requisite corporate and individual
approvals in New Jersey and intends to file for the requisite approvals in other
jurisdictions wherein its product can be legally sold. The Company's gaming
platform was approved for sale in Nevada on March 20, 1997. In addition, the
Company has submitted its product for testing in Mississippi and New Jersey and
with Gaming Laboratories International, Inc., an independent testing facility
located in Tom's River, New Jersey. There can be no assurance that the Company's
product will be approved in any additional jurisdiction other than Nevada. The
regulations relating to Company and product licensing are subject to change, and
other jurisdictions, including the federal government, may elect to regulate or
tax gaming activities. The Company cannot predict the nature of any such changes
or their impact on the Company.

Any beneficial holder of the Company's Common Stock may be subject to
investigation by any gaming authority in any jurisdiction in which the Company
does business if such authorities have reason to believe that such ownership may
be inconsistent with the gaming policies of that jurisdiction. Persons who
acquire beneficial ownership of more than certain designated percentages of the
Common Stock may be subject to certain reporting and qualification procedures.
In addition, changes in control of the Company and certain other corporate
transactions may not be effected without the prior approval of gaming
authorities in other jurisdictions in which the Company plans to do business.
Such provisions could adversely affect the marketability of the Company's Common
Stock or prevent certain corporate transactions, including mergers or other
business combinations.

In the future, the Company intends to store its game software and Machine
Management System/TM/ on a writeable internal hard disk drive that will enhance
data storage and facilitate upgrades to game software. Current technical
standards in Nevada and Colorado prohibit the storage of software affecting game
outcome in a medium that can be altered through the circuitry or programming of
the gaming device. Accordingly, implementation of a writeable internal disk
drive will require a modification to the applicable technical standard or any
similar regulations of any other jurisdictions where the Company intends to sell
its machine. Although the Company believes that the Nevada gaming authorities
may modify the technical standard in the near future in a manner that will
permit the implementation of the Company's current design, there can be no
assurance that such modification will occur in the near future or at all, or
that a similar modification will be made to the regulations of any other
jurisdiction. Moreover, any such modification will be subject to administrative
procedures in Nevada that allow for comment by certain parties currently
licensed under Nevada gaming regulations.  Thus, certain existing or potential
competitors of the Company will have the opportunity to object to modifications
to the technical standard that may be necessary to permit the Company to
implement a writeable hard disk design. There can be no assurance that such
objection will not affect the outcome of this administrative procedure in a
manner that would prevent the Company's implementation of its current platform
design. The Company has altered its product to comply with existing regulations
in Nevada by disabling the write feature of its hard drive in a manner that
could not be changed without violating the integrity of the machine. Although
this alternative limits the machine's ability to store substantial quantities of
game history data during play and the ease of software upgrades, the Company
does not believe that this alternative affects the actual play characteristics
of the Company's games or the operation of the Machine Management System./TM/

DEVELOPMENT STAGE COMPANY; EXPECTATION OF LOSSES; NEGATIVE CASH FLOWS.  The
Company was founded in July 1993 and, as a development stage company, has not
yet generated revenue from product sales or other sources. As of December 31,
1996, the Company had cumulative net losses since inception of $19,614,000, and
the Company expects to continue to incur substantial losses and negative
operating cash flows at least through mid-1998. There can be no assurance that
the Company will become profitable or cash flow positive at any time in the
future. The likelihood of the success of the Company must be considered in light
of the expenses, difficulties, complications and delays frequently encountered
in connection with the formation of a new business and the competitive and
regulatory environment in which the Company must operate. In particular, the
Company's operations to date have focused primarily on product development, and
the Company has little or no experience in the areas of manufacturing, sales,
product distribution or customer support. It is not possible to estimate future
operating expenses and revenue based upon historical operating performance.
Operating results will depend, in part, on matters over which the Company has no
control, including, without limitation, general economic conditions, gaming
regulations and taxes, the ability of the Company to obtain the licenses
necessary to conduct its business, competition, the actual number of orders for
its product and the availability of qualified personnel.

COMPETITION.  The gaming machine industry is characterized by intense
competition, which is based on, among other things, a device's ability to
generate win per machine through product appeal to players, knowledge of
customer requirements such as ease of use, ease of service, support and
training, distribution, name recognition and price. In recent years, the gaming
machine market has been dominated by International Game Technology ("IGT")
which, according to industry sources, captured approximately 75% of the market
in 1996. Because of its extensive market presence, distribution capacity, player
acceptance and financial, technological and other resources, IGT represents
formidable competition.  Several other companies, including Bally Gaming
International, Inc., are established in, or are seeking to enter, the gaming
machine business. Companies in historically unrelated industries, such as Sega
Enterprises LTD ("Sega"), have technological resources that could offer them a
competitive advantage in developing multimedia-based gaming machines. In
general, the Company's existing competitors, as well as many potential new
competitors, have significantly greater financial and technical resources than
the Company, as well as more established customer bases and distribution
channels, which may allow them to move rapidly into the Company's market and
acquire significant market share. Increased competition could result in price
reductions, reduced operating margins and loss of market share, any of which

                                       31
<PAGE>
 
could materially and adversely affect the Company's business, operating results
or financial condition. Furthermore, any success the Company might have may
benefit existing competitors and induce new competitors to enter the market.
There can be no assurance that the Company will be a successful competitor in
the gaming machine industry.

MANAGEMENT OF GROWTH.  Execution of the Company's plan of operation will require
significant growth. The Company's current plans for growth will place a
significant strain on the Company's financial, managerial and other resources.
The Company's ability to manage its growth effectively will require it to
continue to improve its operational, financial and management information
systems and to attract, motivate and train key employees. If the Company's
executives are unable to manage growth effectively, the Company's business,
operating results and financial condition would be materially and adversely
affected.

DEPENDENCE ON KEY PERSONNEL.  The operations of the Company depend a great
extent on the management efforts of its officers and other key personnel and on
the ability to attract new key personnel and retain existing key personnel.
Competition is intense for highly skilled product development employees in
particular. There can be no assurance that the Company will be successful in
attracting and retaining such personnel or that it can avoid increased costs in
order to do so. In addition, the Company's officers and key employees are not
bound by noncompetition agreements that extend beyond their employment at the
Company, and there can be no assurance that employees will not leave the Company
or compete against the Company. The Company's failure to attract additional
qualified employees or to retain the services of key personnel could have a
material adverse effect on the Company's operating results and financial
condition. The Company currently maintains a "key-man" life insurance policy in
the amount of $3 million on the life of Andrew S. Pascal, the Company's
Executive Vice President-Marketing and Game Development.

LIMITED PROTECTION OF INTELLECTUAL PROPERTY RIGHTS; RISK OF LITIGATION.  The
Company regards its product as proprietary and relies primarily on a combination
of trademark, copyright and trade secret laws and employee and third-party
nondisclosure agreements to protect its proprietary rights. Defense of
intellectual property rights can be difficult and costly, and there can be no
assurance that the company will be able effectively to protect its technology
from misappropriation by competitors. In addition, the protections offered by
trademark, copyright and trade secret laws would not prevent a competitor from
designing games having appearance and functionality that closely resemble the
company's games. At present, the company's principal proprietary technology
consists of its game authentication algorithm, which is designed to inhibit the
ability of any person to tamper with the game software resident in its product,
and its random number generator algorithm, which determines the outcome of each
gaming proposition. While the company believes that these algorithms are unique
at present, the algorithms are not patented, and there can be no assurance that
a competitor of the company will not succeed in developing an authentication
algorithm or a random number generator algorithm that performs as well as, or
better than, the company's. Although the company has applied for a U.S. patent
with respect to its authentication algorithm, there can be no assurance that
such patent will be issued or, if issued, that such patent will not be
successfully challenged in subsequent litigation.

As the number of software products in the industry increases and the
functionality of these products further overlaps, software developers and
publishers may increasingly become subject to infringement claims. The Company
may also become subject to infringement claims, with or without merit, that are
brought by competitors who are motivated by a desire to disrupt the Company's
business. Although the Company is not currently aware of any claim that it is
infringing upon any of its intellectual property rights, there can be no
assurance that the Company will not face claims, with or without merit, in the
future. Any such claims or litigation could be costly and could result in a
diversion of management's attention, which could have a material adverse effect
on the Company's business and financial condition. Any settlement of such claims
or adverse determinations in such litigation could also have a material adverse
effect on the Company's business, operating results and financial condition.

RAPIDLY CHANGING TECHNOLOGY.  The Company's product utilizes hardware components
that have been developed primarily for the personal computer and multimedia
industries. These industries are characterized by rapid technological change 

                                      32
<PAGE>
 
and product enhancements. The Company's ability to remain competitive and retain
any technological lead may depend in part upon its ability to continually
develop new slot machine games that take full advantage of the technological
possibilities of state-of-the-art hardware. Should any current or potential
competitor of the Company succeed in developing a competing software-based
gaming platform, such competitor could be in a position to outperform the
Company in its ability to exploit developments in microprocessor, video or other
multimedia technology. The emergence of a suite of slot machine games that is
superior to the Company's in any respect could substantially diminish the
Company's product sales and thereby have a material adverse effect on the
Company's operating results.

CAPITAL REQUIREMENTS.  The Company believes that its cash and equivalents and
short-term investments will be sufficient to fund its capital and operating
requirements. No assurance can be given, however, that the Company will not be
required to seek additional financing to fund its operations. In that event,
there can be no assurance that the Company will be able to obtain such
financing, or that, if it is able to obtain such financing, it will be able to
do so on satisfactory terms or on a timely basis. If additional funds are raised
through the issuance of equity, convertible debt or similar securities, the
percentage of ownership of the Company's shareholders will be reduced,
shareholders may experience additional dilution, and such securities may have
rights or preferences senior to those of the Common Stock. Moreover, if adequate
funds were not available to satisfy the Company's short-term or long-term
capital requirements, the Company would be required to limit its operations
significantly. The Company's capital requirements will depend on many factors,
including, but not limited to, the rate at which the Company can introduce its
product, the market acceptance and competitive position of such product, the
response of competitors to the product and the ability of the Company's
management and its product to satisfy the corporate licensing and product
licensing requirements in various jurisdictions.

LIMITED MANUFACTURING EXPERIENCE.  In order for the Company to be successful,
its product must be manufactured to meet high quality standards in commercial
quantities at competitive prices. Although the Company has produced small
quantities of prototype devices for testing, design, licensing and field testing
purposes, it has only recently attempted to manufacture its product for
commercial distribution. The transition to commercial manufacturing of the
Company's product, either by the Company or by a contract manufacturer, will
involve various risks and uncertainties including unforeseen costs or assembly
difficulties and the possibility that anticipated efficiencies or economies of
scale will fail to materialize as the Company begins manufacturing in greater
volumes. A failure by the Company to successfully manage this transition would
have a material adverse affect on the Company's business, operating results or
financial condition.

DEPENDENCE ON SINGLE-SOURCE SUPPLIERS.  The Company currently obtains a number
of its system's components from single-source suppliers. In particular, the
touchscreen and picture tube that comprise the video display are supplied by
MicroTouch Systems, Inc. and Philips Display Components Company, respectively.
The Company does not have long-term supply contracts with these suppliers but
rather obtains these components on a purchase order basis. Although the design
of these components is not unique or proprietary and the Company believes that
it could identify alternative sources of supply, if necessary, there can be no
assurance that the Company would be able to procure, substitute or produce such
components without a significant interruption in its assembly process in the
event that these single sources were unable to supply these components. The
failure or delay by any supplier to furnish the Company with any such components
would have a material adverse effect on the Company's business, financial
condition and results of operations.

SLOWING IN TREND TO LEGALIZE GAMING.  Growth in demand for slot machines
historically has been driven by the opening of new casinos, including casinos in
jurisdictions where gaming has recently been legalized. However, in recent
years, the legalization of gaming in new jurisdictions has been significantly
reduced; therefore, demand based on new openings will be largely limited to new
projects in existing markets. There can be no assurance that the slot machine
industry will sustain the rate of growth that was possible in the first half of
this decade.

NO DIVIDENDS.  The Company has not paid any cash dividends in the past and does
not expect to do so in the foreseeable future.

1. BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES


BUSINESS--Silicon Gaming, Inc. (the Company) was incorporated on July 27, 1993
to develop and market innovative gaming devices through the use of advanced
multimedia and interactive technologies.

In May 1996, the Board of Directors of the Company approved a two-for-three

shareholders and effected in July 1996. All share and per share amounts in these
financial statements have been adjusted to reflect this split.

As of December 31, 1996, the Company was a development stage company. Successful
completion of the Company's development program and, ultimately, the attainment
of profitable operations is dependent upon future events, including obtaining
regulatory approval of its products and achieving a level of sales adequate to
support the Company's cost structure.

</TABLE>

CONSOLIDATION--The consolidated financial statements include the Company and its
wholly-owned subsidiaries (formed in February 1996) after elimination of
intercompany accounts and transactions.

ESTIMATES--The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of expenses during the reporting period.
Actual results could differ from those estimates.

CASH EQUIVALENTS--The Company considers all highly liquid debt instruments
purchased with an original maturity of three months or less to be cash
equivalents.

SHORT-TERM INVESTMENTS--Short-term investments represent debt securities which
are stated at fair value. The difference between amortized cost (cost adjusted
for amortization of premiums and accretion of discounts which are recognized
as adjustments to interest income) and fair value representing the unrealized
holding gains and losses are recorded as a separate component of shareholders'
equity until realized. While the Company's intent is to hold debt securities to
maturity, they are classified as available-for-sale securities because the sale
of such securities may be required prior to maturity. Any gains or losses on
the sale of debt securities are determined on a specific identification
basis.Inventories--Inventories consist of raw materials and work-in-process and
are stated at the lower of cost or market on a first-in, first-out basis.

                                      38
<PAGE>
 
PROPERTY AND EQUIPMENT--Property and equipment are stated at cost. Depreciation
and amortization are computed using the straight-line method over estimated
useful lives of three to ten years.

RESEARCH AND DEVELOPMENT EXPENSES--Research and development expenses are charged
to operations as incurred. In connection with the Company's product development
efforts, it develops software applications which are integral to the operation
of the product. The costs to develop such software have not been capitalized as
the Company believes its current software development process is essentially
completed concurrent with the establishment of technological feasibility and/or
development of the related hardware.

INCOME TAXES--The Company accounts for income taxes in accordance with Statement
of Financial Accounting Standards No. 109, "Accounting for Income Taxes," which
requires an asset and liability approach for financial reporting of income
taxes.

STOCK-BASED COMPENSATION--The Company accounts for stock-based awards to
employees using the intrinsic value method in accordance with APB No. 25,
Accounting for Stock Issued to Employees.

NET LOSS PER SHARE--Net loss per share is based on the weighted average number
of common shares outstanding subsequent to the Company's initial public offering
in 1996. Common share equivalents including stock options, warrants and
redeemable convertible preferred stock have been excluded, as their effect would
be antidilutive. Pursuant to rules of the Securities and Exchange Commission
Staff, all common and common equivalent shares issued by the Company at a price
less than the initial public offering price during the 12 months preceding the
offering date (using the treasury stock method until shares are issued) have
been included in the calculation of common and common equivalent shares
outstanding for all periods presented prior to the July 1996 initial public
offering.

Realized gains or losses on sales of available-for-sale securities for the year
ended December 31, 1996 were not significant. The cost of securities sold is
based on the specific identification method. Fair values are based on quoted
market prices obtained from independent brokers. Available-for-sale investments
have been classified as current assets as all maturities are within one year.

4. LEASES


In October 1995, the Company obtained a lease line of credit to acquire up to
$1,000,000 of equipment under capital leases with a term of 48 months. The
Company granted the leasing company a warrant to purchase 40,936 shares of
Common Stock at a price of $1.71 per share; such warrant expires in the year
2002 and may be net-exercised by the holder. The estimated fair value of the
warrant, $25,000, has been recorded as a deferred financing cost in other
assets, and is being amortized over the term of the related leases. In December
1995 and during 1996, the Company entered into sale/leaseback arrangements under
this lease line for equipment with an original cost of $333,000 and $667,000,
respectively; no gains or losses were recorded on these transactions.

In September 1995, the Company entered into a facility lease agreement which
expires in 2006 and requires the Company to incur at least $175,000 for net
leasehold improvements in the first three years of occupancy, which the Company
completed in 1996.

Future minimum operating and capital lease commitments at December 31, 1996 are
as follows:

These warrants are exercisable for 116,666 shares of Common Stock at an
exercise price of $7.50 per share. In connection with the initial public
offering, the Company issued 5-year warrants to purchase an aggregate of 177,777
shares of Common Stock to other financial advisors at an exercise price of
$12.60 per share. Warrants to purchase 40,936 shares of Common Stock at an
exercise price of $1.71 were issued to a leasing company in 1995 in connection
with a lease line of credit (See Note 4). All warrants expire in 2001.

Stock Option Plans
- ------------------
Under the 1994 Stock Option Plan (the "Option Plan"), the Company may grant
incentive or nonstatutory stock options up to 2,866,666 shares of Common Stock
to employees, directors and consultants at prices not less than fair
market value for incentive stock options and not less than 85% of fair market
value for nonstatutory stock options. These options generally expire five to ten
years from the date of grant. Options normally vest at a rate of 25% on the
first anniversary of the grant date and 1/48 per month thereafter and may be
exercised at any time, subject to the Company's right to repurchase unvested
shares at the original exercise price upon termination. During the nine months
ended December 31, 1995 and the year ended December 31, 1996, employees
exercised options in exchange for notes payable to the Company of $75,000 and
$152,000, respectively.

In 1996, the Board of Directors adopted the 1996 Outside Directors Stock Option
Plan (the "Directors Plan"). Under this plan, non-employee directors of the
Company are automatically granted initial options to purchase 15,000 shares of
Common Stock and additional options to purchase 5,000 shares of Common Stock in
each subsequent year that such person remains a director of the Company. Options
under the Directors Plan have an exercise price equal to fair market value at
the grant date, vest at a rate of 1/36 per month over three years and expire 10
years from the date of grant. The number of shares authorized under this plan is
200,000.

</TABLE>

At December 31, 1996, 540,908 and 140,000 shares were available for future
grants under the Option Plan and Directors Plan, respectively. At December 31,
1996, 966,471 shares exercised were subject to repurchase.

Employee Stock Purchase Plan
- ----------------------------
In 1996, the Board of Directors adopted the 1996 Employee Stock Purchase Plan
(the 'Purchase Plan'). Under the Purchase Plan, eligible employees are permitted
to purchase shares of Common Stock through salary withholding at a price equal
to 85% of the lower of the market value of the stock at the beginning of the 24-
month offering period or the end of each six-month purchase period, subject to
certain limitations. No shares have been issued under the Purchase Plan as of
December 31, 1996; 300,000 shares were reserved for future issuance.

Additional Stock Plan Information
- ---------------------------------
As discussed in Note 1, the Company continues to account for its stock-based
awards using the intrinsic value method in accordance with APB No. 25,
Accounting for Stock Issued to Employees, and its related interpretations.
Accordingly, no compensation expense has been recognized in the financial
statements for employee stock arrangements.

Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation (SFAS 123), requires the disclosure of pro forma net income and
earnings per share had the Company adopted the fair value method as of the
beginning of fiscal 1995. Under SFAS 123, the fair value of stock-based awards
to employees is calculated through the use of the minimum value method for all
periods prior to the initial public offering, and subsequently through the use
of option pricing models, even though such models were developed to estimate the
fair value of freely tradable, fully transferable options without vesting
restrictions, which significantly differ from the Company's stock option awards.
These models also require subjective assumptions, including future stock price
volatility and expected time to exercise, which greatly affect the calculated
values. The Company's calculations were made using the minimum and Black-Scholes
option pricing models with the following weighted average assumptions: expected
life, 12 months following vesting; stock

                                       43
<PAGE>
 
volatility, 39.2% subsequent to the initial public filing in 1996; risk-free
interest rates, 6% in 1995 and 6.7% in 1996; and no dividends during the
expected term. The Company's calculations are based on a multiple option
valuation approach and forfeitures are recognized as they occur. If the computed
fair values of the 1995 and 1996 awards had been amortized to expense over the
vesting period of the awards, pro forma net loss would have been $3,982,000
($0.49 per share) in 1995 and $14,345,000 ($1.45 per share) in 1996. However,
because options vest over several years and grants prior to 1995 are excluded
from these calculations, these amounts may not be representative of the impact
on future years' earnings, assuming grants are made in those years.


7. INCOME TAXES

The Company has had losses since inception and therefore has not provided for
income taxes.

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amount of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes, as well as operating loss
and tax credit carryforwards. Significant components of the Company's deferred
income tax assets as of December 31, 1995 and 1996 are as follows:

                                                     December 31,

Total                                            $     -    $     -
                                                 ==================

Due to the uncertainty surrounding the realization of the benefits of its
favorable tax attributes in future tax returns, the Company has fully reserved
its net deferred tax assets as of December 31, 1995 and 1996, respectively.

At December 31, 1996, the Company had net operating loss carryforwards of
approximately $18,600,000 and $17,200,000 for federal and state income tax
purposes, respectively. These carryforwards begin to expire in 2000.

The Company also has research and development credit carryforwards of
approximately $240,000 and $250,000 available to offset future federal and state
income taxes, respectively, as of December 31, 1996. These carryforwards begin
to expire in 2010.

Section 382 of the Internal Revenue Code and the applicable California law
impose annual limitations on the use of net operating loss and tax credit
carryforwards if there is a change in ownership, as defined, within any three-
year period. As a result of certain stock offerings, the annual deductibility of
a substantial portion of the federal net operating loss and tax carryforwards
may be limited.


8. RELATED PARTIES

For the year ended March 31, 1995, the nine-month period ended December 31, 1995
and the year ended December 31, 1996, the Company paid approximately $166,000,
$23,000 and $8,000, respectively, to a partnership in which a founder of the
Company is a partner in exchange for management services and administrative
support. Additionally, for the year ended March 31, 1995 and the nine-month
period ended December 31, 1995, payroll and other expenses, including rent,
utilities and travel, amounting to $467,000 and $71,000, respectively, were paid
on behalf of the Company by affiliated companies and were subsequently
reimbursed by the Company.
