Item 1.  Business

General

Tseng Labs, Inc. ("Tseng" or the "Company") is one of the foremost designers and
suppliers of high performance video graphic controller chips in the world. The
Company's accelerators are designed to enhance the personal computer's (PC(TM))
performance by reassigning the graphic function from the Central Processing Unit
(CPU) to the accelerator. By working in conjunction with the personal computer's
CPU, the graphic accelerator can offer significant improvement to the quality of
the graphics and also improve the system's overall performance.

Incorporated in 1983, Tseng has built a long-standing reputation as an
innovative company offering technological advancements and reliable products to
the graphics market. This reputation has resulted in Original Equipment
Manufacturers (OEM) agreements with some of the most respected names in the
computer industry. These OEMs, as well as many other customers, believe that
Tseng products provide the capabilities and reliability that are needed for PC
video solutions.

Tseng has long been considered a pioneer in the graphics market. The Company
successfully introduced the ET4000(TM) chip set in 1989. The ET4000 has the
distinction of being the most successful SVGA controller in history. Following
the debut of the ET4000, the Company offered a series of products designed to
accentuate its video capabilities and performance. The result was the systematic
introduction of the W32(TM), W32i(TM), W32p(TM) and the Video Image Processor
(VIPeR(TM)), respectively. As the demand for greater multimedia capabilities,
3D, and teleconferencing takes hold in the consumer marketplace, Tseng is
focused on offering solutions to meet and exceed those expectations. The Company
is currently in the process of bringing to market the ET6000(TM), the first in a
family of next generation graphics controller products.

Markets and Products

PC Graphics Since VGA

Following the advent of the IBM PS/2(TM) series of personal computers in 1987,
the era of video graphics array (VGA(TM)) arrived. Tseng Labs, on the strength
of its fast response to VGA with its ET3000(TM) controller, quickly became
recognized as a leader in the market of VGA-compatible video graphics products.
Operating at 640x480 screen resolution with 16 to 256 colors and a refresh rate
of 60Hz, VGA greatly improved the productivity of the PC user. Microsoft had
recently introduced Windows(R) 3.0 which utilized a graphical user interface
(GUI). GUI interfaces provide a more user-friendly environment while allowing
the user to use a mouse or pointing device to select particular applications or
documents. Graphics became extremely important following the Windows
introduction. With graphics, however, came the desire for greater speed and
higher screen resolutions. Unfortunately, higher speed and resolution placed a
heavy burden upon the resources of the CPU. Subsequently, graphic chips
represented a way to utilize the new interface while maintaining the speed and
power of the system. While the VGA standard represented a quantum leap ahead of
its predecessors, it had its own set of limitations, which drove graphic
companies in search of a higher standard. The VGA standard became the building
block for the next generation of graphic controllers, the Super VGA (SVGA(TM)).

The Company was influential as a pioneer of SVGA. Introduced as a solution to
limited screen resolution and colors, SVGA was later ratified by the Video
Electronics Standards Association (VESA) as the standard for the graphic
industry. Operating originally at 800x600 screen resolution while maintaining
the 16 to 256 color palette and between 60Hz and 72Hz refresh, SVGA was widely
accepted by third-party developers of standards and accelerated chip sets.
During this period, Tseng Labs reinforced its position as a leader in design and
engineering with the ET4000 chip set targeting the SVGA standard.

The advent of Microsoft Windows 3.0(TM) and 3.1(TM) allowed for GUI interfaces
for applications running on the PC. Unfortunately, Windows noticeably diminished
the processing power of the computer due to its highly graphical operating
environment. The Company, along with other graphics companies, realized that
high speed, high resolution graphical interfaces needed to be provided. The
graphics industry saw an opportunity in providing high resolution and color
while improving performance by reassigning video responsibilities to the
graphics card, thereby accelerating the entire system.

                                       1
<PAGE>

In 1989, the Company introduced the ET4000 controller. The ET4000 grew to become
one of the single highest volume SVGA-compatible devices ever produced,
permitting 1024x768 resolution at 256 colors, while using low cost DRAM. In
addition, the low cost ET4000-based adapters were capable of displaying 16.8
million colors simultaneously, allowing for "true color" imaging on a low cost
adapter. The ET4000 was the first SVGA class device to be connected to the CPU
directly, which is now referred to as a "local bus" implementation. With a
properly designed graphics chip, local bus provides the CPU with far greater
access to the graphics memory, increasing the performance of the entire display
subsystem. The ET4000 was noticeably faster than other SVGA chips, allowing the
CPU to write to the video card without losing access time to the video memory,
known as "wait states," typical in previous technology.

The next advance in GUI software required better acceleration than that
available from zero wait state and local bus operation. The Company answered
with the ET4000/W32, which retained full compatibility with the ET4000 software,
but increased it from a 16-bit to a 32-bit local bus which was more appropriate
for 486 CPU designs. The W32 allowed the CPU to write to the video memory at the
same or faster rates than to its own system memory, and included an ability to
power Windows and other applications between four and ten times faster than the
acceleration of the original ET4000. Because of its price/performance value, the
W32 was integrated onto the system motherboards of a number of leading OEMs.

Windows Acceleration for 2D and Developing 3D

The market demand for performance graphics increased substantially after the
release of Microsoft's Windows 3.0 and follow-up Windows 3.1. Many manufacturers
of PCs chose to bundle Windows, or other GUI software package such as OS/2(R),
with every system. An explosion of high-resolution and high-color applications
authored for Windows occurred. By the end of 1992, the best selling DOS
applications in word processing, spreadsheets, graphics and desktop publishing
among others, had migrated to the Windows GUI application interface. This
additional layer of software hampered the performance of many applications by
increasing software execution time.

Windows demanded more power from the graphic accelerator hence, the W32i and the
W32p were introduced to provide additional performance, resolution and color,
and higher levels of integration to reduce system chip count and cost. The W32i
was the direct replacement for the W32 on OEM designs. The W32p delivered the
memory interface of the W32i with the direct connection of PCI local bus
architecture, an emerging industry standard. Both the W32i and the W32p enhanced
graphic systems performance by using an approach known as memory interleaving
that doubled the graphics processing power of the device. The original W32 chip
provided a 32-bit path between the graphics controller and its memory. The W32i
and W32p used interleaving to effectively double the path to 64-bits, with only
a minimum incremental cost to deliver the enhanced performance. In addition, the
W32i and W32p could process 64-bits of graphic data in the same time that the
original W32 could process 32-bits of graphic data.

By 1992, many of the most popular applications which specified hardware sets
such as EGA(TM), or VGA/SVGA had been re-written to support the GUI environment.
PC users benefited from this trend by having a multitude of applications that
now run in higher resolution and/or higher color modes on their non-IBM
hardware. However, as the graphical environment has become more important, so
has the need for increasingly powerful graphics hardware to maintain the users'
expectation for GUI application performance.

The Company has always sought to further enhance video technologies through
additional advancements regarding their products. Additionally, the Company has
played an important role in the development and sanctioning of industry
standards. In 1995, Windows 95(TM) was introduced by Microsoft. The Windows 95
operating system offered software developers the capability of drastically
improving graphics and video performance over Windows 3.x. Game and
entertainment titles depend on quick screen updates driven by real-time input
from a mouse, joystick, or other device to maintain the illusion of realism.
These title developers largely avoided porting their products from DOS to
Windows, unable to accept the performance penalty Windows 3.x GDI (Graphics
Device Interface) presented. By accessing the PC graphics hardware directly
under DOS, interactive titles achieve the performance they need but lost the
hardware independence that Windows applications enjoy. Windows 95 offered the
best of both worlds, and represented an innovative departure from the
traditional GUI as a "layer" between user and the operating system.

Windows 95 offers application developers access to a set of programming
interfaces that provide a thin layer of abstraction over graphics and multimedia
hardware acceleration features. Writing to this set of interfaces, known as
DirectX(TM), gives applications high performance and hardware independence as
well as access to other Windows 95 features. This performance boost allows
Windows 95 to be positioned as a compelling multimedia operating system for home
as well as professional use. In late 1995, game developers began releasing the
first wave of titles to take advantage of DirectX. As this list of software


                                       2
<PAGE>

continues to grow, the Company believes that the demand for graphics solutions
that are optimized for Windows 95 performance will continue to increase.

In November 1995, the Company responded with the introduction of the ET6000
during Fall Comdex, and was awarded the Best of Comdex in the Sound and Display
category. The ET6000 is a state-of-the-art 128 bit graphics and multimedia
engine that integrates a high quality video processor, a revolutionary interface
to Multibank(TM) DRAM (MDRAM) and PCI bus interface. Optimized for Windows 95
graphics performance, the ET6000 was designed to offer high resolution and color
without system degradation. As has characterized the PC industry, users continue
to require greater video performance, speed, higher resolution, and greater
bandwidth between the graphics chip and graphics memory. The Company responded
with a 128-bit graphics and multimedia engine using MDRAM which resulted in a
high quality video processor. The ET6000 will also continue the Company's trend
of integrating technology by bringing two important circuits, the RAMDAC and
clock generator, inside one single chip, positioning the Company to more
effectively compete with a number of its competitors who currently offer this
level of integration.

To complement the ET6000 chip's internal video processing engine and to reduce
the required components for multimedia video applications, the Company
introduced two multimedia processors, the VPR6000(TM), a video image processor,
and the MPG9920(TM), and MPEG decoder with built-in scaling capabilities. The
VPR6000 processes video, enables live video input, and allows ISA and other
multimedia devices to reside on the Company's proprietary Image Memory Access
(IMA) multimedia bus. The MPG9920 allows glueless attachment to the ET6000 for
hardware playback of MPEG video. The MPG9920 also features an internal video
scaler and input for live video. Both devices were designed to allow OEMs to
create feature-rich, highly integrated, PCI compliant, low cost multimedia
solutions. The Company is currently working to bring the ET6000, VPR6000 and the
MPG9920 to commercial production.

Video, Multimedia, and Entertainment

Advancing technologies including faster microprocessors and higher performance
memory have allowed microcomputers to perform more than traditional data
processing applications. Multimedia is the mixing of entertainment,
communications, and data processing capabilities. The Company views multimedia
as an opportunity for growth in a rapidly emerging video market. The majority of
multimedia titles are based upon communications, productivity, information,
education and entertainment applications. Multimedia is a developing technology
that places increased burdens on system hardware due to full-motion video
requirements. An integral component of a multimedia computer is the display of
live and stored motion video, and audio at the highest resolution and refresh
rates.

Broadcast video displays at relatively low resolution, but high color. The
perceived quality of the display is created by rapid (30 times per second)
changes in the motion video. With the W32-family of graphic controllers, the
Company introduced a method to display color and resolution beyond the
television color standard. By bringing the motion data into memory, a PC can
digitally store or modify the motion data. In both engineering and market
opportunity, Multimedia represents a challenge and an opportunity for growth for
the Company.

Other Multimedia video solutions, including live video stored using the Motion
Picture Experts Group (MPEG) standard, have been introduced into the market.
MPEG compression enables feature film motion pictures to be compressed onto
standard CD-ROMs. Applications for MPEG technology include home entertainment,
education, information kiosks, and others. The Company's graphics and multimedia
products have been combined with MPEG-specific chips from other parties to form
solutions addressing this market. The Company believes that the demand of the
market for higher quality display will favor the currently emerging MPEG-2
standard. The new standard provides for greater throughput of the data resulting
in a smoother, more realistic picture, without losing any picture frames. To
accomplish this standard, MPEG-2 requires more performance from the graphics
chip. The Company believes the ET6000 is ideally suited for MPEG-2 applications
due to its increased bandwidth capacity, high resolution display capability, 128
bit GUI accelerator, use of MDRAM and advanced high quality multiple scaled
window display capability. The Company is also currently developing additional
products and evaluating technology from other parties to attempt to develop
solutions for this emerging market.

The Company has developed technology that responds to the trend toward more
feature oriented computer systems. All of the members of the W32- family of
graphic controllers include two input paths to the display memory. The first
path is for CPU bus data, and is standard on most SVGA and GUI accelerator
chips. The second path is proprietary to the Company and is called Image Memory
Access (IMA(TM)). IMA architecture allows video input from a live TV source or
multimedia coprocessor directly into the display memory. In 1994, the Company
provided the VIPeR chip as an IMA bus device to handle display and capture of
live motion video, and to accelerate replay of motion video playback from


                                       3
<PAGE>

inexpensive and popular software decompression products like Intel's Indeo. The
VIPeR allows motion data to be dynamically sized in a window in real time,
requiring no recalculation time by the system CPU, meaning that proportional
resizing of the video image window is virtually instantaneous. The video image
window can be adjusted for brightness, contrast, and saturation, and also
coexist on-screen with traditional data processing applications. The VIPeR, when
introduced, was found to be a cost-effective product for displaying broadcast
television in a digital window on the personal computer. The high quality image
processing of VIPeR allowed MPEG images to be enlarged without creating a
blocky, unrealistic image often found in other MPEG products. In 1995, the
Company introduced the VIPeR f/x which gave the user higher resolution video
display and other enhancements.

Computer purchasing trends in the US have leaned towards multimedia machines
since 1994. These PCs included a CD-ROM, speakers and a sound card, allowing the
user to access a host of information with high quality speed and sound.
Moreover, a greater percentage of computers began to ship to the home market as
opposed to the workplace. As a result, the computer industry now offers hardware
and software for home entertainment, education, on line accesses and searches,
and productivity.

The largest growth segments in home entertainment is internet access and gaming
applications, using home multimedia computers. Game applications have become the
testing grounds for today's processors, graphic cards, and audio. Historically,
the games applications were somewhat limited in terms of speed (if the
application was developed in Windows) or graphics (if the application was
developed in DOS). In 1995, Microsoft provided the interface and performance
necessary for the development of high quality video games for the PC with the
development of Windows 95, allowing all the performance of the DOS based
applications with the interface of a Windows application (see "DirectX" in the
previous section).

Through the use of DirectX, Windows 95 addresses the issues of performance and
graphics necessary in gaming and teleconferencing applications. DirectX allows
for a clear and direct path to real-time, real-motion video and the development
of true 3D applications. The ET6000 was designed to allow the user to take
advantage of the additional capabilities available in Windows 95. The ET6000
also included the capabilities of the entire W32-family of chip sets as well as
the integration of portions of the multimedia features currently available in
the VIPeR chip set series. The ET6000 and its emerging family of products is
being designed to produce high-performance graphics at the resolution and color
depths previously available on very high-end, more costly video solutions.

Factors Which May Affect Results

The Company cautions readers that it operates in a highly competitive and
rapidly changing technology marketplace and that there are many factors,
including those discussed below that, in some cases have, and may in the future,
affect the Company's operating results and could cause the Company's actual
consolidated results for one or more future periods to differ materially from
those expressed in any forward-looking statement made by, or on behalf of, the
Company. Statements in this section and other sections of this Form 10-K which
are not historical statements constitute forward looking statements.

The competition in the markets which the Company competes is intense. The market
is characterized by rapid technological change, short product lives (typically
less than 18 months) and severe price competition. The Company is continually
attempting to develop new products to address market requirements. If new
products are not brought to the market in a timely manner or do not address the
market performance and price requirements, then sales and operating results in
future periods could be adversely affected. In addition, if the Company is not
able to effect a smooth transition from one product to another, competitive
forces in the market, including pricing and margin pressures, could result in
substantial fluctuations in quarterly operating results and adversely impact
sales and operating results in future periods. Competitive factors to be
considered include but are not limited to, the timing of new products,
performance, features, price, product availability, breadth of product line and
customer support.

The Company's historical operating results have been, and its future operating
results may be, subject to fluctuations, including quarterly fluctuations due to
a variety of factors including, but not limited to, changes in pricing policies
by the Company or its competitors, including anticipated and unanticipated
decreases in average unit selling prices, concentration of a high percentage of


                                       4
<PAGE>

total sales in a few significant customers, gain or loss of significant
customers, cancellations or rescheduling of orders by customers, changes in
product or customer mix, new product introductions and acceptance by the Company
or its competitors, market acceptance of new or enhanced versions of the
Company's or competitors' products, strengths or weaknesses in the overall
markets in which the Company competes and sensational demand. In addition,
because the Company must order product and build inventory substantially in
advance of customer orders and product shipments and because the markets for the
Company's products are volatile and subject to rapid technological and price
changes, there is a risk that the Company will forecast incorrectly and produce
excess or insufficient inventories of particular products which could adversely
impact operating results.

The semiconductor industry as a whole is characterized by a high percentage of a
total sales in a quarter occurring in the third month of a quarter.
Historically, based upon customer demand, the Company has shipped more product
in the third month of each quarter than in either of the first two months. In
addition, shipments in the third month are often higher at the end of the month.
Accordingly, a disruption at the end of a quarter of either production or
shipping could materially impact operating results in that quarter. In addition,
such concentration can cause difficulties in both forecasting production
requirements for a product and/or forecasting operating results for a quarter.

The Company currently relies on outside foundries, packaging houses and test
houses for the manufacturing of its semiconductor devices. The use of third
parties involves many significant risks including, but not limited to, the
absence of adequate capacity to produce the Company's products, unavailability
of, or interruptions in access to the process technologies necessary to
manufacture the Company's products, the absence of guaranteed manufacturing
capacity, reduced control over delivery schedules, manufacturing yields and
costs. The Company is currently attempting to qualify a number of additional
foundries to provide additional production capacities for the Company's new
products. However, the qualification process and production ramp-up is a complex
process and could take longer than anticipated and there can be no assurance
that such foundries will be able or willing to produce parts in quantities, in
the time frames and at the price necessary to satisfy both the Company and
customer requirements. In addition, customers may be unable or unwilling to
qualify parts from multiple sources. The inability to meet customer requirements
and price points for delivery of products could adversely impact future
operating results.

In addition to the risks associated with delivery of the Company's products, the
PC and the graphics subsystem rely on a number of component parts produced by
third parties. In addition, the Company's ET6000 has been designed to attempt to
optimize the additional memory bandwidth of Multibank DRAM (MDRAM) by Mosys,
Inc. Mosys, Inc. is also a "fabless" semiconductor supplier and may be subject
to risks similar to the Company with respect to many of the business risks
discussed above including, but not limited to, reliance on outside foundries.
Any shortage of components used in the PC or graphics subsystem could affect the
Company's operating results.

Sales and Marketing

The Company employs traditional OEM channels to market its products. The Company
utilizes an internal sales and marketing team responsible for all aspects of
both domestic as well as international sales. Additionally, the Company uses a
series of independent manufacturers representatives and regional distributors,
to provide marketing and technical support for its customers. The Company
maintains close working relationships with its customers and potential customers
and periodically exchanges advance technical information with them under
nondisclosure agreements. The Company has initiated on-going programs for
continuous improvement geared towards customer satisfaction and fulfillment.

In North America, the Company uses a combination of a direct sales force
operating from the Company's main headquarters in Newtown, Pennsylvania and
independent manufacturers representatives. The manufacturers representatives are
located in Massachusetts, Alabama, Pennsylvania, North Carolina, Georgia,
California, Texas, Washington, and Oregon.

Internationally, the Company also operates an Asian sales and support office
located in Taipei, Taiwan with local distributors located in Hong Kong, Japan,
Korea, Singapore, as well as Taiwan. The European customers are serviced using a
direct sales labor force based at the Company's headquarters and manufacturers
representatives located in Belgium, Germany, and the United Kingdom.

As the Company's customer base has largely become OEM and add-in board
manufacturers, it has discontinued sales through distribution of its own brand
name products. The Company promotes the acceptance and use of its products
through direct contact with potential customers, coverage in trade and press
articles, and participation in industry trade shows.

During 1995, 1994, and 1993, sales to the Company's two largest customers
accounted for 37%, 51%, and 42% respectively, of the Company's revenues. One
customer represented 42% of revenues in 1994. This customer did not contribute
significantly to revenues in 1995. In addition, sales to unaffiliated
distributors, primarily in the Far East, accounted for 12%, 9% and 8% of total
revenues for 1995, 1994, and 1993, respectively. (See Note 7 to the Company's
consolidated financial statements). The Company expects a significant portion of
its future sales to remain concentrated within a limited number of strategic
customers. Sales to these customers can fluctuate significantly from quarter to
quarter. In addition, orders from these customers may be subject to cancellation
or rescheduling. There can be no assurance that loss or significant fluctuations
in quarterly sales to the Company's significant customers (including but not
limited to canceling and/or rescheduling orders) may not adversely impact the
Company's operating results in the future.

Foreign sales, including those to the Far East distributors, represented
approximately 59%, 43% and 41% of revenues during 1995, 1994, and 1993,
respectively. As a significant portion of the Company's sales are export sales,
the Company is subject to the risks of conducting business internationally,
including unexpected changes in regulatory requirements, fluctuations in the US
dollar which could increase the sales price in local currencies of the Company's
products in foreign markets, tariffs, and other barriers and restrictions and
the burden of complying with a wide variety of foreign laws.

Product Support and Service

The Company believes that customer service and technical support are of
paramount importance in obtaining and preserving a competitive advantage in the
graphic accelerator market. To that end, the Company provides technical support
to its OEM and add-in board manufacturers through support staffs located in its
Newtown headquarters and in its Taiwan office. Additional support for the
Company's products is provided by manufacturers representatives and
distributors. Tseng also offers support via an electronic bulletin board
service, evaluation boards, product design support, demonstration software, and
a soon to be completed world wide web site on the internet. Additionally, the
Company provides application design support and upgrading of customer software.
By providing the latest enhancements for its products through software upgrades,
the Company can extend the life and value of its products to the customer.

The Company will periodically provide product road maps, under non-disclosure
agreements, to OEMs and add-in board manufacturers. The Company believes that
such communication will improve customer satisfaction while enhancing the
Company's corporate image. Additionally, the Company believes it can better
understand current and future system requirements through a consistent dialog
with its customers. It is the Company's belief that customer satisfaction is
improved through open communication. Furthermore, the Company believes it can
identify important trends and concerns which assist in defining future products
and services.

Manufacturing

Historically, the Company has purchased all of its product from one foundry. The
Company has developed and is implementing a strategy for major new products of
utilizing a number of qualified foundries that it believes provide the
technology, capacity, quality and cost required to support production of that
product. The Company's products are manufactured utilizing CMOS processes with
line geometrics as small as 0.6 micron. Most of the Company's new products are
manufactured using advanced triple metal processes. The Company has an on-going
program of evaluating foundries with even smaller geometries for future
products. While the Company's strategy is to develop multiple sources for its
major new products to reduce its dependency on any single foundry, improve its
flexibility to respond to customer requirements, increase the Company's ability
to fulfill customer requirements, and gain greater control over its production
costs, the Company has not qualified second sources for certain of its products.
In addition, new products (including the ET6000) are typically produced
initially by a single foundry until alternate sources can be qualified. The
Company currently does not have long-term contractual supply agreements with its
foundries. Historically, the Company has conducted its business with its
foundries by written purchase orders which cover a period or range of periods.
Should a foundry terminate its relationship with the Company, or its supply from
a foundry be interrupted for any other reason, the Company may not be able to
replace, on a timely basis, the production loss from this foundry.

The Company is working with existing foundries to obtain additional production
for its new products (including the ET6000) and is working to qualify new
foundries to provide additional manufacturing capacity for its products
(including the ET6000). The Company has commenced product development with
additional foundries and has agreed to pay for certain non-recurring engineering
costs and initial production and, subject to qualification of these foundries,
has made certain purchase commitments. If there are significant delays in
qualifying new foundries, shipments of products could be delayed, which could
adversely affect operating results.



                                       6
<PAGE>

Prior to 1995, the Company's foundry also performed the packaging and testing
functions necessary to deliver finished, tested parts to the Company. The
Company paid only for finished, tested parts meeting predetermined
specifications. In 1995, the Company began purchasing product in wafer and
"known good die" forms and managed the subcontracting by third parties of the
assembly and test process. In 1996, the Company anticipates the majority of its
product will be purchased in wafer or "known good die" form. In the assembly
process, wafers are tested in accordance with predetermined specifications
established by the Company and assembled into packaged parts. The packaged parts
are again tested to the Company's specifications. Product returns to date have
not been significant.

The Company's reliance on third party foundries involves a number of risks
including, but not limited to, the absence of adequate capacity, the
unavailability of, or interruptions in access to the process technologies
utilized by the Company's products, the absence of guaranteed capacity, reduced
control over delivery schedules, manufacturing yields and costs. Inability to
obtain adequate, timely supply sources, whether due to capacity constraints,
disruption at foundry, assembly or test, delays in qualification of new
foundries or other reasons, could adversely affect the Company's operating
results.

In order to obtain an adequate supply of wafers, especially wafers manufactured
using advanced process technologies, the Company has considered and will
continue to consider various possible transactions, including the use of "take
or pay" contracts which commit the Company to purchase specified quantities of
wafers over specified periods or the use of standby letters of credit to secure
future capacity on a "take or pay" basis. In addition, a number of the Company's
competitors have entered into various transactions to secure wafer capacity
including equity investments in or advances to wafer foundries in exchange for
guaranteed production, or the formation of joint ventures to own, construct or
operate a wafer fabrication facility. The Company, to date, has not participated
in advance funding or joint ventures and will continue to work to secure
adequate capacity without such arrangements. Should the Company be required to
enter into any of the above manufacturing arrangements to secure foundry
capacity, such arrangements may require substantial capital investment, which
may require the Company to seek additional equity or debt financing, and there
can be no assurance that such additional financing, if required, will be
available when needed or, if available, will be on satisfactory terms. In
addition, the Company may, from time to time, as business conditions warrants,
invest in or acquire businesses, technology or products that complement the
business of the Company. No such investments or acquisitions are being
negotiated as of the date of this document.

The Company's current foundries and the additional foundries that it is working
to qualify are primarily located in the Far East, Europe and the Mid-East.
Fluctuations in the value of the US dollar against local currencies could impact
the price paid by the Company for its products.

In addition to adequate supply of the Company's products, PCs and graphics
subsystems rely on a number of other components, produced by third parties. Any
shortage of such components could adversely affect the Company's business and
operating results.

Research and Development

The Company believes that a continued investment in engineering personnel and
resources is critical to its ability to timely develop and introduce new
products and allow it to become or to remain a leader in the markets in which it
competes. This investment in the engineering personnel is viewed as critical to
this effort and competition for attracting and retaining qualified personnel is
intense. The Company conducts most of its product development in-house with an
engineering staff of 50 personnel. The Company is currently working to further
leverage its design resources by both jointly developing products with
technology partners (the MPG9920 is an example of this joint development) and/or
utilizing outside, third party contractors to assist in the development of new
products and the portation of existing products to additional foundries.

The Company uses advanced workstations, dedicated simulators, and a variety of
modeling and layout tools to design products. The engineers also use a high
level design language in the development of products. The Company is committed
to continuing to invest in state-of-the-art computer aided engineering (CAE) and
computer aided design (CAD) tools, to enable its engineers to effectively and
efficiently develop new products which are tested using a variety of hardware
and software modeling simulations. Additional support related to software driver
development and firmware are also located on-site to further enhance Tseng's
ability to bring product to market in the quickest, most cost-efficient manner.


                                       7
<PAGE>

Once developed, the Company offers development kits to customers and potential
customers to assist them in developing products based upon Tseng's technology.

The efforts of the Company resulted in the development of the ET6000 and its
family of products along with its predecessor W32 and ET4000 product families.
During 1995, 1994, and 1993 the Company spent approximately $3,440,000,
$1,922,000 and $1,011,000, respectively, on research and development activities.

Competition

The Company competes in a highly competitive marketplace numbering some 50+
participants. The principal competitive factors in the market for PC enhancement
products are price, performance, brand recognition, product quality,
availability, breadth of product line, service and OEM support, the timing of
new product introductions by the Company and its competitors and the emergence
of new standards for graphics, multimedia and PCs. Price competition in the
industry is intense and may increase.

The Company's principle competitors include S3, Inc., Cirrus Logic, Inc., ATI
Technologies, Inc., Trident Microsystems, Inc. and Matrox, Inc. Many of the
Company's competitors have greater financial resources, more extensive business
experience and greater design, development, manufacturing, marketing and service
capabilities than the Company. The rapid pace of technological change in the
computer and computer enhancement market places a premium on such factors as the
knowledge and experience of the Company's management and personnel and their
ability to develop and improve products. For these reasons, the Company believes
its future success to be directly linked to the development and introduction of
new products that are responsive to market needs. There can be no assurance that
the Company will be able to successfully develop or market such products in a
timely manner.

Licenses, Patents and Trademarks

Historically, the Company principally relied upon its advanced technological
innovations to enable it to compete in the graphics accelerator market. The
Company has recently applied for its first ever patent for certain proprietary
functions included in the newly developed ET6000 series. No patents have been
issued to the Company to date. The Company has attempted to protect its
technologies and proprietary information through non-disclosure agreements with
its customers, suppliers, employees, and consultants. The Company intends to
attempt to aggressively protect its intellectual property.

The Company has been issued trademarks for UltraPak and EVA (an application of
the ET2000 chip) and its ET3000, ET4000, ET4000/W32, W32i, and W32p-based chip
and board products. The Company has also filed trademark registrations for its
upcoming ET6000, VPR6000, and MPG9920 products. The Company believes that an
active trademark program is important to developing and maintaining recognition
in the market for its products.

Backlog

The Company's business, and to a large extent that of the entire semiconductor
industry, is characterized by short lead-time orders and frequent cancellation,
rescheduling and price negotiation of orders. Sales of the Company's products
have been historically made pursuant to purchase orders that are cancelable, at
the customers' option, without significant penalties. Because of the above
factors, the Company does not believe that backlog is a meaningful indicator of
sales in any future period.

Employees

As of March 1, 1996, the Company had 95 full-time employees. Of these, 9 were
engaged in operations; 50 in product and software development; 17 in marketing,
customer service and support; and 19 in management, administrative and financial
positions.

Item 2.  Properties

The Company owns a building with 34,000 square feet in an industrial and office
park in Newtown, Pennsylvania which is used as its advanced research and product
development facility, as well as its principal executive office. The Company
occupied this facility on February 1, 1992.

Item 3.  Legal Proceedings

In May 1993, two purported shareholders of the Company brought an action against
the Company and certain of its executive officers in the United States District
Court for the Eastern District of Pennsylvania, alleging that the defendants had
issued false and misleading statements concerning the Company and thus had
violated the federal securities laws and committed common law fraud and
negligent misrepresentation. Subsequently, several other purported shareholders
filed similar actions in the same forum against the Company and certain of its
executive officers. The actions have been consolidated. On July 8, 1994,
pursuant to stipulation, the Court certified a class for the federal securities
law claims and dismissed the state law claims, without prejudice. Discovery had
been completed and on August 21, 1995, the Company filed a motion for summary
judgment seeking to dismiss the action in its entirety. On March 19, 1996, the
Court ruled on the Company's motion and dismissed the action in its entirety.
The Company had recorded the expense in defending these complaints on an as
incurred basis.

On March 22, 1996, the closing bid price in the over-the-counter market of the
Company's Common Stock, as reported by the National Quotation Bureau was $9.63.
The high and low closing bid prices of the Company's Common Stock between
January 1, 1996 and March 22, 1996 were $8.63 and $10.63 respectively.

In August 1995, the Company's Board of Directors voted to suspend the Company's
quarterly cash dividend which had commenced in August 1993. Two dividends of
$.05 per share were paid to holders of the Company's Common Stock in 1995 and
four dividends of $.05 per share were paid in 1994. The Company does not
anticipate paying cash dividends in the foreseeable future and currently
intends, as most of its competitors currently do, to retain its cash and
earnings for the development of its business.

Item 7. Management's Discussion and Analysis of Financial Condition and Results
of Operations

Statements in this section other than historical statements constitute forward
looking statements and actual results could materially differ from those
expressed in any forward looking statements by the Company. See "Factors That
May Impact Results."

Results of Operations

Revenues for 1995 were $39,277,000 a 51% decrease from 1994 levels. The decrease
in revenues was due primarily to significantly lower shipments of the Company's
W32i-based products as these products reached maturation in a rapidly evolving
personal computer marketplace. Sales of W32i-based products to one customer
accounted for 42% of revenues in 1994. This entity discontinued its W32i-based
computer systems in the first quarter of 1995. Higher sales of W32p-based
products were not sufficient to offset lower unit shipments of the W32i and
lower selling prices on all of the Company's graphics accelerator products. The
Company introduced the first product of its third generation graphics and
multimedia family, the ET6000, at Comdex in November 1995. This product family
is not yet in full volume production. Due to short product design cycles in the
computer industry as a whole, announced and anticipated new product
introductions by competitors of the Company, and anticipated design changes from
major customers, the Company expects pricing and competitive market pressures on
existing products will continue to intensify and revenues and earnings will
continue to be lower than 1995 levels unless and until the ET6000 becomes a
commercially successful product. In addition, because of the risks in bringing
new technologies to market and market acceptance of new products, in the
production process of semiconductor devices, in the availability and cost of
materials from the Company's suppliers and due to the competitive nature of the
graphics and PC market, there can be no assurance that revenues and earnings
from the ET6000 will be sufficient to return the Company's operating results to
historic levels.

Revenues for 1994 and 1993 were $80,659,000 and $75,526,000, respectively. While
sales only increased 6.8% between periods, the product mix comprising the sales
changed significantly between years. The Company began a product transition late
in the first quarter of 1993 when sales of the Company's first generation
graphics accelerator product (the W32) began to contribute significantly to the
Company's revenues. The W32 was the first in a family of products introduced by
the Company to enhance video performance, especially in Microsoft Windows and
other Graphical User Interface (GUI) applications. The Company also introduced
its second generation accelerator products in 1993 and sales of the W32i and
W32p contributed significantly to revenues late in the third and fourth quarters
of 1993, respectively, and continued into 1994. For the years ended December 31,
1994 and 1993, sales of products of the full W32 family represented
approximately 90% and 71% of total revenues, respectively. In 1994 alone, sales
of the second generation accelerator products (W32i and W32p) represented
approximately 85% of total revenues. Also contributing to revenues in 1994 was
the Company's new video accelerator, VIPeR. Revenues based upon the newer
technologies substantially replaced revenues based upon the Company's older
ET4000-and W32-based technology. In addition to a change in the technology
underlying the Company's products, there was a change in product mix between
years. Unit shipments of the Company's VLSI graphics chips increased slightly in
1994. Sales of board level enhancement products continue to decrease primarily
due to lower cost alternatives available in other markets including the Far
Eastern markets. Average selling price on VLSI graphics chips also increased
slightly in 1994 as lower average selling prices on the ET4000-and W32-based
technology in 1994 were offset by higher selling prices for the Company's W32i
- -and W32p based family of products as well as the new VIPeR. The Company expects
selling prices on existing technologies to continue to decrease as a result of
the competitive nature of the graphics marketplace and the PC market as a whole.

Cost of sales as a percentage of revenues was 74% for 1995, 71% for 1994 and 69%
for 1993. The increase in cost of sales in 1995 and 1994 is due to the fact that
the impact of cost reduction programs on the W32i and W32p graphics accelerator
products has not been sufficient to offset lower selling prices on all of the
Company's products. Also contributing to the increase in 1995 was a one-time
reserve of $735,000 recorded by the Company in the fourth quarter related to
establishing a reserve for certain of its older technology-based inventory. In
addition, because of the price competitive nature of the market, anticipated
pricing pressures on mature products and the current volatility in the
yen/dollar exchange rate, the Company expects increased pricing pressures
impacting margins on its existing W32 product line.

In the future, the Company's gross margin percentages may be affected by factors
including but not limited to increased competition and related decreases in unit
average selling price (particularly with respect to mature products), timing of


                                       11
<PAGE>

volume shipments of new products, the introduction of new products by
competitors, the availability and cost of products from the Company's suppliers
and changes in the mix of products sold and customers.

Research and development expense in 1995 was $3,440,000, a 79% increase from
1994. Research and development expense in 1994 was $1,922,000, a 90% increase
from 1993. The increase in both periods is due primarily to increased personnel
and outside consulting costs to support development of its third generation
graphics products, including the ET6000, and due to the pursuit of new
opportunities to expand the Company's product line to address multimedia
applications. The Company expects that its research and development expenditures
will continue to increase in 1996 as the Company attempts to develop products
which respond to emerging markets in desktop PCs, home PCs and interactive
communication markets.

Selling, general and administrative expenses were 16%, 8% and 8% of revenues in
1995, 1994 and 1993, respectively. The increase in 1995 is due primarily to both
the fixed nature of certain of the Company's operating expenses and increased
legal costs associated with the class action lawsuit referred to in Note 6 of
the consolidated financial statements.

The Company's effective income tax rates were 17.6%, 35.8% and 34.2% for 1995,
1994 and 1993, respectively. The decrease in the effective tax rate in 1995 is
primarily due to estimated research and development credits representing a
higher percentage of pretax income. The increase in the effective tax rate in
1994 was primarily due to a higher effective state income tax.

Inflation is not expected to have an adverse significant impact on the Company's
operations.

LIQUIDITY AND CAPITAL RESOURCES

The Company's ability to generate cash adequate to meet its requirements results
primarily from cash on hand, operating cash flow and the availability of bank
borrowing. The Company believes that these sources are sufficient to fund the
Company's 1996 working capital requirements.

Total working capital was $47,155,000 and $50,431,000 at December 31, 1995 and
1994, respectively. The Company's cash and short-term investments increased to
$39,214,000 at December 1995 from $38,542,000 at December 31, 1994. The increase
is due primarily to the excess of cash generated from operations over that
required to fund its capital requirements, stock repurchases, and dividend
program. The Company also has a bank line of credit providing total availability
of $2,500,000. There were no borrowings on this line in 1995 or 1994.

The Company had capital expenditures of approximately $2,211,000 during 1995,
related primarily to the purchase of equipment and software utilized in the
Company's research and development activities. The Company expects its existing
sources of liquidity to be sufficient to fund its 1996 working capital and
capital expenditure requirements.

In order to obtain an adequate supply of wafers, especially wafers manufactured
using advanced process technologies, the Company has considered and will
continue to consider various possible transactions, including the use of "take
or pay" contracts which commit the Company to purchase specified quantities of
wafers over specified periods or the use of standby letters of credit to secure
future capacity on a "take or pay" basis. In addition, a number of the Company's
competitors have entered into various transactions to secure wafer capacity
including equity investments in or advances to wafer foundries in exchange for
guaranteed production, or the formation of joint ventures to own, construct or
operate a wafer fabrication facility. The Company, to date, has not participated
in advance funding or joint ventures and will continue to work to secure
adequate capacity without such arrangements. Should the Company be required to

Compensation Pursuant to Plans

The Company has adopted three Stock Option Plans (the 1984, 1991 and 1995 Stock
Option Plans) (the "Plans") The 1995 Plan, subject to shareholder approval,
provides for the grant of stock options to purchase up to 3,000,000 shares of
the Company's Common Stock. The 1991 and 1984 Stock Option Plans provide for the
grant of stock options to purchase an aggregate of 3,000,000 shares of the
Company's Common Stock. Eligible participants under the Plans include officers
and other key employees and consultants, as defined in the Plans.

Effective with the approval of the 1995 Plan, all three plans are administered
by a Committee composed of non-employee directors. The 1991 and 1984 Plans had
been administered by two Stock Option Committees. One Committee was composed of
non-employee directors with respect to principal officers of the Company (as the
term "officer" is defined in Rule 166-1(f) under the Securities Exchange Act of
1934, as amended), while the Committee with respect to non-principal officers
was comprised of three directors who are also officers of the Company.

Under the 1995 and 1991 Stock Option Plans, the Company may grant non-qualified
stock options, incentive stock options or a combination thereof. The 1984 Stock
Option Plan provides only for the granting of non-qualified stock options. The
option exercise price for both incentive and non-qualified stock options granted
under the Plans may not be less than the fair market value of the Common Stock
on the date the stock option is granted. To date, all grants under the Plans
have been non-qualified stock options. Participants who receive non-qualified
stock options will be deemed to receive taxable income at ordinary income rates
upon exercise for the difference between the exercise price and the fair market
value of the Company's Common Stock at the date of exercise.

At December 31, 1995, the Company had outstanding options to purchase an
aggregate of 1,659,300 shares of Common Stock at exercise prices ranging from
$3.00 to $13.75 per share, with a weighted average price per share exercise
price of $7.89. A total of 2,676,493 shares of Common Stock are available for
future issuance under the Plans.

Non-Employee Director Compensation

Directors who are not employees receive an annual retainer of $20,000 plus
reimbursement for out-of-pocket expenses. The Company also has a stock option
plan for non-employee directors ("Directors Plan") under which the outside
directors are granted options at fair market value to purchase Common Stock.
Directors receive options to purchase 20,000 shares of Common Stock upon their
initial election to the Board and additional options for every two years of
service on the Board. The options vest 50% at grant and 50% on the first
anniversary of grant. At December 31, 1995, a maximum of 80,000 additional
options may be granted under the plan. At December 31, 1995, 87,500 options were
outstanding under the plan at an average exercise price of $10.59 per share. The
outside directors exercised 2,500 options to acquire shares of the Company's
Common Stock in 1993. There were no options exercised by outside directors in
1995 and 1994.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Tseng Labs, Inc:

We have audited the accompanying consolidated balances sheets of Tseng Labs,
Inc. (a Utah corporation) and subsidiaries as of December 31, 1995 and 1994, and
the related consolidated statements of income, shareholders' equity and cash
flows for each of the three years in the period ended December 31, 1995. These
financial statements and the schedule referred to below are the responsibility
of the Company's management. Our responsibility is to express an opinion on
these financial statements and schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Tseng Labs, Inc. and
subsidiaries as of December 31, 1995 and 1994, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1995, in conformity with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in the index at Item
14 is presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in the audits of
the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                        TSENG LABS, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BACKGROUND:

Tseng Labs, Inc. is a developer of custom semiconductor devices and board level
enhancement products that expand the graphics capabilities and performance of
IBM and IBM-compatible personal computers.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Principles of Consolidation

The consolidated financial statements include the accounts of Tseng Labs, Inc.
and its wholly owned subsidiaries (the Company). All significant intercompany
transactions and balances have been eliminated. The preparation of financial
statements in conformity with generally accepted accounting principals requires
management to make estimates and assumptions that affect the reported amounts of
assets, liabilities, contingent liabilities, revenues and expenses during a
reporting period. The Company operates in very competitive and rapidly changing
markets. Actual results could differ from management estimates.

Inventories

Inventories, which consist of materials, labor and overhead, are stated at the
lower of weighted average cost or market and consist of the following (in
thousands):

                                                     December 31
                                          -----------------------------------
                                             1995                       1994
                                             ----                       ----
Purchased parts                           $   662                    $ 3,379
Finished goods                              2,746                        407
                                          --------                  ---------
                                          $ 3,408                    $ 3,786
                                          =======                    =======

The Company recorded a charge to cost of sales in the fourth quarter of 1995 of
approximately $735,000 related to a potential decline in value of certain older
technology-based inventory.

Plant and Equipment

Plant and equipment are stated at cost. Depreciation is computed using the
straight-line method over the following estimated useful lives:

Building                          25 years
Equipment                         5-7 years
Furniture and Fixtures            10 years

Depreciation expense was $1,080,000, $862,000 and $523,000 in 1995, 1994, and
1993, respectively.

                                       F-6
<PAGE>

Deferred Costs

Research and development costs incurred in developing the Company's proprietary
chips are charged to expense until technological feasibility has been
established. Thereafter, all costs incurred in refining and testing the chips
are capitalized. These deferred costs are amortized on a product-by-product
basis over the estimated revenue stream of the related product. Management
periodically evaluates whether factors indicate that there is an impairment of
the deferred costs and, accordingly, the carrying value is adjusted to reflect
such impairment, if any. During 1995, the Company wrote-off approximately
$307,000 of deferred costs which were identified as not recoverable over the
revenue stream of future generation products. Approximately $1,284,000 of the
unamortized deferred costs at December 31, 1995, relate to products for which
development has been completed and sales have commenced. Amortization was
$1,451,000 in 1995, $1,238,000 in 1994, and $825,000 in 1993.

Net Income Per Share

Net income per share is computed using the treasury stock method based on the
weighted average number of common stock and common stock equivalents outstanding
during each year.

Cash and Short-Term Investments

The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents for the purpose of
determining cash flows.

The Company adopted Statement of Financial Accounting Standard No. 115
"Accounting for Certain Investments in Debt and Equity Securities" (SFAS No.
115) effective January 1, 1994. Management determines the appropriate
classification of debt securities at the time of purchase and reevaluates such
designation as of each balance sheet date. As of December 31, 1995, all of the
Company's short-term investments were U.S. Government securities which have been
classified as hold to maturity and reflected at amortized cost in the
accompanying balance sheet. The estimated fair value of each investment
approximated cost at December 31, 1995. There was no cumulative effect as a
result of adopting SFAS No. 115 in 1994.

Concentration of Credit Risk

Financial instruments which potentially subject the Company to concentration of
credit risk consist primarily of cash equivalents, short-term investments and
accounts receivable. By policy, the Company places its investments only with
high-quality financial institutions and, other than U.S. government Treasury
instruments, limits the amounts invested in any one institution or type of
investment. Substantially all of the Company's accounts receivable are derived
from sales to manufacturers of computer systems, subsystems and value-added
resellers. The Company performs ongoing credit evaluations of its customers'
financial condition. Approximately 59%, 43% and 41% of the Company's sales in
1995, 1994 and 1993, respectively, were export sales. To date, substantially all
such sales have been in U.S. dollars. To reduce credit risk, the Company
generally requires international customers to furnish letters of credit.
Historically, the Company has not incurred material credit-related losses.

Revenue Recognition

Revenue is recognized upon product shipment. Accruals for estimated sales
returns and allowances are recorded at the time of sale. Also included in
revenues is interest income of $2,113,000, $1,241,000 and $881,000 for 1995,
1994 and 1993, respectively.

                                       F-7

Income Taxes

Effective January 1, 1993, the Company adopted Statement of Financial Accounting
Standard No. 109. "Accounting for Income Taxes" (SFAS No. 109). Under SFAS No.
109, the Company provides a deferred tax expense or benefit equal to the change
in the deferred tax liability or asset during the year. Deferred income taxes
reflect the net tax effects of temporary differences between the carrying
amounts of assets and liabilities for financial reporting purposes and the
amounts used for income tax purposes, as well as operating loss and tax credit
carry forward, if any.

Recently Issued Financial Standards

In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121 which establishes accounting standards
for the impairment of long-lived assets, certain identifiable intangibles and
goodwill related to those assets to be held and used for long-lived assets and
certain intangibles to be disposed of. The Company is required to adopt SFAS No.
121 effective January 1, 1996. The adoption of SFAS No. 121 is not expected to
have a material effect on the Company's financial condition or results of
operation.

In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No.123, "Accounting for Stock-Based
Compensation." The Company's adoption of SFAS 123 in 1996 is not expected to
have a material effect on the Company's financial position or results of
operations, as the Company intends to continue to measure the compensation cost
of stock option plans using the intrinsic value-based method.

Reclassifications

Certain prior year balances have been reclassified to conform to the current
year presentation.

3. LINE OF CREDIT:

The Company has an unsecured $2,500,000 demand line of credit with a bank. The
line bears interest at prime and places limits on, among other things,
additional long-term debt, payment of dividends and capital expenditures. There
were no borrowings under the line in 1995 and 1994.

4. INCOME TAXES:

As discussed in Note 2, the Company adopted SFAS No. 109 as of January 1, 1993.
The cumulative effect of the adoption was not material and, therefore, is not
reported separately in the statement of income.

Income taxes are comprised of the following (in thousands):

Income tax expense differs from the amount currently payable because certain
revenues and expenses are reported in different periods for financial reporting
and tax purposes. The principal differences involve the timing of deducting
software development costs and different methods used in computing financial
statement and tax depreciation.

A reconciliation of the statutory federal income tax rate to the Company's
effective tax rate follows:

The Company's deferred tax assets, both individually and in the aggregate, are
not material at December 31, 1995 and 1994.

5. STOCK OPTION PLANS:

During 1995, the Company adopted, subject to stockholder approval, the 1995
stock option plan which permits the issuance of either incentive or nonqualified
stock options to employees and nonqualified options to key consultants. A
maximum of 3,000,000 shares of common stock has been reserved for issuance under
this plan. The Company also has two additional nonqualified stock option plans
(the 1991 and 1984 stock option plans) under which a maximum of 3,000,000 shares
of common stock have been reserved for issuance. Options under all three plans
must be granted at a price not less than 100% of the fair market value of the
common stock on the date of grant. Options granted under the plans become
exercisable as determined by the Stock Option Committees of the Board of
Directors at the time of the grant and may have terms extending to 10 years.

A summary of stock options activity related to these plans is as follows:

                                                                 Aggregate

<PAGE>

As of December 31, 1995, a maximum of 2,464,000 and 212,493 additional options
may be granted under the 1995 and 1991 plans, respectively. No additional
options may be granted under the 1984 plan. There were 832,400 options with an
average exercise price of $7.65 per share exercisable at December 31, 1995. The
options expire on various dates through 2005. In January 1995, the Company
canceled and reissued 273,000 options which had been outstanding under the
plans. These options had an average exercise price of $12.09 per share and
represented all outstanding options under the 1991 plan held by non-officers of
the Company. The re-issue price of the options was $5.625 per share.

In July 1991, the Board of Directors adopted the Special Directors Stock Option
Plan, under which outside directors are granted options at fair market value to
purchase common stock. Directors receive options upon their initial election to
the Board and additional options for every two years of service on the Board.
The options vest 50% at grant and 50% on the first anniversary of grant. A
maximum of 200,000 shares have been reserved for grant under the plan. As of
December 31, 1995, a maximum of 80,000 additional options may be granted under
this plan. At December 31, 1995, 87,500 options were outstanding under the plan
at an average exercise price of $10.59 per share. During 1993, the outside
directors exercised options to acquire 2,500 shares of common stock at $6.875
per share. There were no options exercised in 1995 and 1994 by outside
directors.

During the three-year period ended December 31, 1995, the Company purchased all
of its video graphics chips from one foundry. The Company is currently working
to expand the number of foundries from which it purchases its video chips. The
use of third parties to manufacture, package and test the Company's products
involves a number of significant risks including, but not limited to, the
absence of adequate capacity to produce the Company's products, unavailability
of, or interruptions in access to the process technologies necessary to
manufacture the Company's products, the absence of guaranteed manufacturing
capacity and reduced control over delivery schedules, manufacturing yields and
costs. The Company has various purchase commitments, including commitments to
its foundries, at current market prices for materials and supplies used in the
ordinary course of business.

In May 1993, two purported shareholders of the Company brought an action against
the Company and certain of its executive officers in the United States District
Court for the Eastern District of Pennsylvania, alleging that the defendants had
issued false and misleading statements concerning the Company, and thus had
violated the federal securities laws and committed common law fraud and
negligent misrepresentation. Subsequently, several other purported shareholders
filed similar actions in the same forum against the Company and certain of its
executive officers. The actions have been consolidated. On July 8, 1994,
pursuant to stipulation, the Court certified a class for the federal securities
law claims and dismissed the state law claims, without prejudice. Discovery has
been completed and on August 21, 1995, the Company filed a motion for summary
judgment seeking to dismiss the action in its entirety. On March 19, 1996, the
Court ruled on the Company's motion and dismissed the action in its entirety.
The Company had recorded the expense of defending these claims on an as incurred
basis.

In addition to the complaints discussed above, the Company is involved in
certain legal actions and claims arising in the ordinary course of business.
Management, after discussion with legal counsel, believes that the outcome of
such litigation and claims will not have a material adverse effect on the
Company's financial position.

7. EXPORT SALES AND MAJOR CUSTOMERS:

The Company's primary operations are located in the United States. The Company
sells its products primarily into the personal computer market in the United
States, Europe and Asia. Sales into the Asian market are primarily through six
unaffiliated distributors. Total export sales, including sales to the
distributors discussed above, were 59%, 43% and 41% of the Company's sales in
1995, 1994 and 1993, respectively. Two customers accounted for 37% and 30% of
revenues in 1995 and 1993, respectively. One customer accounted for 42% of
revenue in 1994.

8. RELATED-PARTY TRANSACTIONS:

The Company has participated in a round of financing and has invested $818,000
in a minority interest in preferred stock of a start-up multimedia product
company. The Company has also advanced this entity $541,000 in the form of a
secured interest bearing note and advance funded approximately $75,000 of
customer receivables for this entity. The Company is carrying this investment at
cost. This entity is in the start-up stage and is incurring operating losses.
Sales to this entity were approximately $180,000 in 1995.
