 PART I

ITEM 1. BUSINESS

        When used in this report, the words "expects," "anticipates,"
"estimates" and similar expressions are intended to identify forward-looking
statements. Such statements, which include statements concerning the timing of
availability and functionality of products under development, product mix,
trends in average selling prices, the percentage of export sales and sales to
strategic customers and the availability and cost of products from the Company's
suppliers, are subject to risks and uncertainties, including those set forth
under "Management's Discussion and Analysis of Financial Condition and Results
of Operations -- Factors That May Affect Our Results" and elsewhere in this
report, that could cause actual results to differ materially from those
projected. These forward-looking statements speak only as of the date hereof.
The Company expressly disclaims any obligation or undertaking to release
publicly any updates or revisions to any forward-looking statements contained
herein to reflect any change in the Company's expectations with regard thereto
or any change in events, conditions or circumstances on which any such statement
is based.

        Trident Microsystems, Inc. ("Trident" or the "Company") designs,
develops and markets very large scale integrated circuit ("IC") videographics
and audio products for the desktop and portable personal computer (PC) market.
The Company's graphics, video and audio controllers typically are sold with
software drivers, a BIOS and related system integration support. The Company's
strategy is to apply its design expertise, which helped it succeed in the market
for Super Video Graphics Array ("SVGA") graphics controllers and GUI
accelerators, to other high volume graphics and multimedia markets such as
Digital Media for the general mass public, flat-panel LCD controllers for
notebooks, acceleration of Digital Versatile Disc ("DVD") based live-video
playback, and three-dimensional ("3D") display for game and entertainment
applications.

        The overall PC marketplace is characterized by extreme price competition
and rapid technological change as leading PC systems manufacturers compete among
themselves and other PC clone makers for market share. As a result, PC systems
manufacturers require low-cost, feature-rich, advanced graphics and multimedia
solutions. The Company believes that the systems manufacturers are moving
towards reducing system cost to the sub-$1000 level by purchasing IC graphics
and multimedia solutions that integrate functions formerly performed by several
separate components. Moreover, as DVD and video processing capabilities become
more popular, an increasing percentage of computer users require a
high-performance, low-cost graphics system that can display photo-realistic
images or display full-motion video on a sub-$1000 PC system.

        The Company's overall strategy is to capture these market opportunities
by using its design expertise to develop and manufacture videographics and
multimedia products that offer a superior combination of price, performance and
features. The Company is employing this strategy in the fast-growing graphics
and multimedia markets with significant volume potential and is focusing on
providing high performance and feature-rich products that it believes will
appeal to leading PC systems manufacturers.

MARKETS AND PRODUCTS

        Trident has targeted the PC desktop, portable, and multimedia markets.
The desktop market is the largest segment of the PC industry for the Company's
graphics and multimedia products and is characterized by intense price
competition and rapid technological advances. The desktop market includes
adapter card manufacturers, who build graphics controllers onto adapter cards
that serve as graphics subsystems, and PC systems manufacturers and motherboard
suppliers, who may either include adapter cards in their systems or design
graphics controllers onto their motherboards. Following the first two 3D
products of 3DImage975 and 3DImage985, the Company introduced the third 3D
product, Blade 3D.

        Trident entered the portable market in 1995, and is now one of the
leading companies in the market. The Company's portable strategy is to leverage
its superior product positioning and continue to deliver the broadest product
offering in the industry. The Company's product line includes: a) 2D 64-bit
controllers, the Cyber9382 and Cyber9385 (with TV-Output), b) 3D portable
graphics controllers, the Cyber9397 and Cyber9397DVD


                                       3

(3D/AGP/DVD integrated), c) embedded SDRAM graphics controllers, the Cyber9388
(2D/PCI/2MB integrated), the Cyber9525DVD (3D/AGP2x/DVD/2.5MB integrated), the
CyberBlade e4-128 (3D/AGP2x/DVD/4MB integrated), and d) integrated core-logic
graphics controller, the CyberBlade i7 (3D/AGP/DVD/north bridge). The Company's
development direction is a three-way technology drive with 3D, DVD, and embedded
SDRAM solutions. Trident's portable vision is to be "The only other chip on the
notebook(SM)" by integrating 2D/3D, DVD, AGP embedded memory, and audio in the
future into one product. The CyberBlade e4-128 and the Cyber9525DVD together
with the Cyber9388 are the tangible core of this vision.

        The Company has made a major effort to design products to fill the needs
of leading PC systems manufacturers as well as the needs of adapter card
manufacturers. Sales to leading PC systems manufacturers represented
approximately 26% of net sales for fiscal 1999.

PRODUCTS UNDER DEVELOPMENT

        The Company continues to invest in product development programs which it
considers crucial to its success. In particular, the Company is investing in
extensions to its current desktop, portable and multimedia product lines in an
attempt to maintain product competitiveness particularly in the important area
of 3D graphics and multimedia including video and audio. New product development
also continues in technologies where further integration is likely to be needed
and may be applied throughout the Company's product line.

        There can be no assurance that the Company will be able to successfully
complete the development of these products or to commence shipments of these
products in a timely manner, or that product specifications required by the
market will not change during the development period. In addition, even if
successfully developed and shipped, there can be no assurance that new products
will be successful in the marketplace.

SALES, MARKETING AND DISTRIBUTION

        The Company sells its products primarily through direct sales efforts.
The Company has sales offices in Taipei, Taiwan; Hong Kong, China; Houston,
Texas and Santa Clara, California. The Company's offices are staffed


                                       6
<PAGE>   7

with sales, applications engineering, technical support, customer service and
administrative personnel to support its direct customers. The Company also
markets its products through independent sales representatives and distributors.

        The Company's desktop customers have been primarily Asian adapter card
manufacturers who sell their products to PC manufacturers, VARs and
distributors. However, in the past few years leading systems manufacturers have
significantly increased their share of the PC market, displacing in part some of
the Asian adapter card manufacturers. While many manufacturers based in Asia may
sell PCs to leading systems manufacturers for resale, the choice of components
for these PCs generally is made by the leading systems manufacturers. The
Company has made a major effort to design products to fill the needs of leading
PC systems manufacturers as well as the needs of adapter card manufacturers.

        The Company's notebook customers have been primarily worldwide brandname
portable PC manufacturers and Taiwanese OEM/ODM portable PC manufacturers. The
product is distributed through brandname sales channels. With long design-in
cycles, the Company has solid technical support to ensure successful product
launching and delivery.

        Trident's future success depends in large part on the success of its
sales to leading systems manufacturers. The Company continues to focus its sales
and marketing efforts with the goal of increasing sales to the leading PC
systems manufacturers and OEM channels. Competitive factors of particular
importance in such markets include performance and the integration of functions
on a single IC chip.

        During fiscal 1999, the Company generated 73% of its revenues from Asia
and 27% from North America and the rest of the world. Major systems
manufacturers often take delivery of their products in Asia for production
purposes, and such sales by the Company are reflected in the Company's revenues
in Asia. Sales to two customers, Fujitsu and Innoquest accounted for
approximately 13% and 12% of net sales, respectively, for fiscal 1999. A small
number of customers frequently account for a majority of the Company's sales in
any quarter. However, sales to any particular customer may fluctuate
significantly from quarter to quarter. Future operating performance may be
dependent in part on the ability to replace significant customers or win new
design-ins with current customers from one quarter to the next. Fluctuations in
sales to key customers may adversely affect the Company's operating results in
the future. For additional information on foreign and domestic operations, see
Note 9 of Notes to Financial Statements.

MANUFACTURING

        Trident has adopted a "fabless" manufacturing strategy whereby Trident
contracts-out its wafer fabricating needs to qualified contractors that it
believes provide cost, technology or capacity advantages for specific products.
As a result, the Company has generally been able to avoid the significant
capital investment required for wafer fabrication facilities and to focus its
resources on product design, quality assurance, marketing and customer support.
The Company has, however, made a substantial investment in a manufacturing joint
venture as described below. Trident's wholly-owned subsidiary, Trident
Microsystems (Far East) Ltd. ("Trident Far East"), manages the manufacturing
operations of the Company.

        In order to obtain an adequate supply of wafers, especially wafers
manufactured using advanced process technologies, the Company entered into a
joint venture agreement in August 1995 with United Microelectronics Corporation
("UMC"), a Taiwanese publicly traded company and one of the Company's current
foundries, under which the Company invested a certain amount of New Taiwan
dollars, equivalent to approximately U.S.$49.3 million for a 7.25% equity
interest in a joint venture with UMC and other venture partners. The Company has
been guaranteed a certain percentage of total wafer supply from the wafer
fabrication facility of the venture, United Integrated Circuits Corporation
("UICC"). The UMC agreement is expected to provide the Company with substantial
additional capacity; however, it will also expose the Company to certain
financial risk if the Company does not obtain enough purchase orders from its
customers to consume the capacity or if the joint venture is not successful in
its operations. Part of the joint venture foundry facility was destroyed in a
fire on October 3, 1997. In


                                       7
<PAGE>   8

June 1999 the Company announced that it had received confirmation from UMC that,
subject to the approval of the UMC shareholders and the Taiwan government, the
UICC joint venture will be consolidated with UMC by the end of 1999. Trident
expects to receive approximately 46.5 million shares of UMC stock in the
consolidation. These shares represent about 0.5% of the outstanding stock of
UMC. As the consolidation is subject to UMC shareholder approval, no assurance
can be given as to whether such shares will be received. The Company has not
determined whether or when it will sell such shares and the shares may be
subject to trading or other restrictions. Following the consolidation, Trident
will continue to have a guaranteed wafer supply from UMC approximately the same
in quantity as it had with UICC.

        In fiscal 1999, the Company's primary foundries were UMC and Taiwan
Semiconductor Manufacturing Company ("TSMC"). The Company also received
additional capacity from Samsung Semiconductor, Inc. and Winbond Electronics
Corporation. In January 1997, the Company renegotiated its June 1995 wafer
purchase agreement with TSMC. This agreement committed the Company to purchase
and the supplier is to provide a certain number of wafers each year. In January
1997 TSMC reimbursed U.S.$14.4 million to Trident in conclusion of this
agreement, but the Company and TSMC continue to maintain their semiconductor
foundry relationship. The Company will continue to explore arrangements for
additional capacity commitments, although there is no assurance that any
additional agreements will be executed, or that additional capacity is required.

        The Company purchases product in wafer form from the foundries and
manages the contracting with third parties for the chip packaging and testing.
In order to manage the production back-end operations, the Company has been
adding personnel and equipment to this area. The Company's goal is to increase
the quality assurance of the products while reducing manufacturing cost. To
ensure the integrity of the suppliers' quality assurance procedures, the Company
has developed and maintained test tools, detailed test procedures and test
specifications for each product and requires the foundry and third party
contractors to use those procedures and specifications before shipping finished
products. The Company has experienced few customer returns based on the quality
of its products. However, Trident's future return experience may vary because
its newer, more complex products are more difficult to manufacture and test. In
addition, some of its customers, including major PC systems manufacturers may
subject those products to more rigid testing standards than in the past.

        The Company's reliance on third party foundries and assembly and testing
houses involves several risks including the absence of adequate capacity, the
unavailability of or interruptions in access to certain process technologies,
and reduced control over delivery schedules, manufacturing yields, quality
assurance and costs. The Company conducts business with certain foundries by
delivering written purchase orders specifying the particular product ordered,
quantity, price, delivery date and shipping terms and, therefore, except as set
forth in the above-mentioned contracts or agreements, such foundries are not
obligated to supply products to the Company for any specific period, in any
specific quantity or at any specified price, except as may be provided in a
particular purchase order.

        While the Company has obtained and continues to seek additional
capacity, the qualification process and the production ramp-up for additional
foundries has in the past taken and could in the future take longer than
anticipated. There can be no assurance that such additional capacity from
current foundries and new foundry sources will be available and will satisfy the
Company's requirements on a timely basis or at acceptable quality or per unit
prices. Constraints or delays in the supply of the Company's products, whether
because of capacity constraints, unexpected disruptions at the foundries or
assembly or testing houses, delays in additional production at existing
foundries or in obtaining additional production from existing or new foundries,
shortages of raw materials, or other reasons, could result in the loss of
customers and other material adverse effects on the Company's operating results,
including effects that may result should the Company be forced to purchase
products from higher cost foundries or pay expediting charges to obtain
additional supply. In addition, to the extent the Company elects to use multiple
sources for certain products, customers may be required to qualify multiple
sources, which could adversely affect the customers' desire to design-in the
Company's products.

RESEARCH AND DEVELOPMENT

        The Company conducted substantially all of its product development
in-house and had a staff of 237


                                       8
<PAGE>   9

research and development personnel as of June 30, 1999. The Company is focusing
its development efforts primarily on the development of more advanced graphics
controllers, including 3D graphics controllers, flat panel controller products
for notebook PCs and multimedia products. In addition, the Company intends to
continue to devote significant resources to the development of a broad range of
high-performance, proprietary software drivers. In anticipation of future market
demand, the Company is investing in a variety of new technologies through
licensing and purchase arrangements. These technologies may be incorporated in
the Company's future products, providing additional functionality and
integration.

COMPETITION

        The markets in which the Company competes are highly competitive and the
Company expects that competition will increase. The principal factors of
competition in the Company's markets include, but are not limited to price,
performance, the timing of new product introductions by the Company and its
competitors, product features, the emergence of new graphics and other PC
standards, level of integration of various functions, quality and customer
support. The Company's principal current competitors in graphics include 3Dfx
Interactive, Inc., ATI Technologies, Inc., Chips and Technologies, Inc. (an
Intel subsidiary), Intel Corporation, Matrox, NVIDIA Corporation, NeoMagic,
Inc., S3 Inc. and Silicon Integrated Systems and potential competitors including
certain large semiconductor manufacturers such as National Semiconductor
Corporation, and emerging semiconductor manufacturers. Current competitors in
audio include Creative Labs, Inc., ESS Technology, Inc., and Cirrus Logic, Inc.
Certain of the Company's current competitors and many potential competitors have
significantly greater technical, manufacturing, financial and marketing
resources than the Company.

        Leading PC systems manufacturers have increased market share in desktop
and portable PC systems in recent years. The Company believes that performance,
features and quality are particularly important in the North American, Japanese
and European systems manufacturer markets, and that integration of various
functions on a single IC is becoming increasingly important in these markets.
While the Company has recently gained entry to these geographic markets, there
can be no assurance that the Company will continue to be able to compete
successfully as to price or any other factor or that the Company will continue
to be successful in its efforts to expand sales in these markets. The failure of
the Company to meet the technological and pricing challenges of its competition
would have an adverse effect on the Company's results of operations.

INTERNATIONAL OPERATIONS

        The Company's wholly-owned subsidiary, Trident Far East, maintains
offices in Hong Kong, China and Taipei, Taiwan. Trident Far East is responsible
for the manufacturing of the Company's products and is principally responsible
for international sales activities and for operation of the Hong Kong and Taiwan
offices. The Hong Kong office provides sales and technical support for customers
in Hong Kong and logistical support for customers in Hong Kong and Taiwan. The
Taiwan office provides sales and technical support for customers in their
respective regions. The Taiwan office directly hires its own employees. The
Company has established research and development facilities in Hsinchu, Taiwan
and Shanghai, China.

        During fiscal 1999, 1998 and 1997, sales to OEM, ODM, and adapter card
customers in Asia accounted for approximately 73%, 84% and 74% of the Company's
net sales, respectively, and the Company anticipates that sales to customers in
Asia will continue to account for a substantial percentage of sales. In
addition, the foundries that manufacture the Company's products are located in
Asia. Due to this concentration of international sales and manufacturing
capacity in Asia, the Company is subject to the risks of conducting business
internationally, including unexpected changes in regulatory requirements,
fluctuations in the U.S. 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 burdens of complying with a wide variety of
foreign laws. In addition, the Company is subject to general geopolitical risks,
such as political and economic instability and changes in diplomatic and trade
relationships, in connection with its sales, support and third-party fabrication
efforts in Hong Kong, Taiwan and elsewhere. The Company's sales have been
adversely affected recently by the general economic decline in Asia. Also,
political instability or significant changes in economic policy could disrupt
the Company's operations in


                                       9
<PAGE>   10

foreign countries or result in the curtailment or termination of such
operations. While the Company has not experienced any other material adverse
effects on its operations as a result of other regulatory or geopolitical
factors, there can be no assurance that such factors will not adversely impact
the Company's operations in the future or require the Company to modify its
current business practices.

INTELLECTUAL PROPERTY

        The Company attempts to protect its trade secrets and other proprietary
information primarily through agreements with customers and suppliers,
proprietary information agreements with employees and consultants and other
security measures. Although the Company intends to protect its rights
vigorously, there can be no assurance that these measures will be successful. We
have filed one U.S. patent application relating to our technology. There can be
no assurance that this application will be approved, that any issued patents
will protect our intellectual property or that they will not be challenged by
third parties. Furthermore, there can be no assurance that others will not
independently develop similar or competing technology or design around any
patents that may be issued.

        The semiconductor industry is characterized by frequent litigation
regarding patent and other intellectual property rights. From time to time, the
Company has received notices claiming that it has infringed third-party patents
or other intellectual property rights. To date, licenses generally have been
available to the Company where third-party technology was necessary or useful
for the development or production of the Company's products. However, NeoMagic
Corporation has filed suit alleging that the Company's embedded DRAM graphics
accelerators infringe their patents. The Company has responded and filed a
counterclaim, which is described in more detail under "Item 3. Legal
Proceedings." There can be no assurance that this litigation will be resolved in
favor of the Company or that third parties will not assert additional claims
against the Company with respect to existing or future products or that licenses
will be available on reasonable terms, or at all, with respect to any
third-party technology. The NeoMagic litigation or similar litigation to
determine the validity of any third-party claims could result in significant
expense to the Company and divert the efforts of the Company's technical and
management personnel, whether or not such litigation is determined in favor of
the Company. In the event of an adverse result in any such litigation, the
Company could be required to expend significant resources to develop
non-infringing technology or to obtain licenses to the technology that is the
subject of the litigation. There can be no assurance that the Company would be
successful in such development or that any such licenses would be available.
Patent disputes in the semiconductor industry have often been settled through
cross licensing arrangements. Because the Company currently does not have a
portfolio of patents, the Company may not be able to settle any alleged patent
infringement claim through a cross-licensing arrangement. In the event any third
party made a valid claim against the Company or its customers and a license was
not made available to the Company on commercially reasonable terms, the Company
would be adversely affected. In addition, the laws of certain countries in which
the Company's products have been or may be developed, manufactured or sold,
including the People's Republic of China, Taiwan and Korea, may not protect the
Company's products and intellectual property rights to the same extent as the
laws of the United States of America.

        We may in the future initiate claims or litigation against third parties
for infringement of our proprietary rights to determine the scope and validity
of our proprietary rights. Any such claims, with or without merit, could be
time-consuming, result in costly litigation and diversion of technical and
management personnel or require us to develop non-infringing technology or enter
into royalty or licensing agreements. Such royalty or licensing agreements, if
required, may not be available on acceptable terms, if at all. In the event of a
successful claim of infringement and our failure or inability to develop
non-infringing technology or license the proprietary rights on a timely basis,
our business, operating results and financial condition could be materially
adversely affected.

BACKLOG

        Because the Company's business is characterized by short lead-time
orders and quick delivery schedules, the Company seeks to ship products within a
few weeks of receipt of orders. As a result, the Company operates without
significant backlog, and relies on bookings each quarter to comprise a
predominant portion of its sales for that quarter. Additionally, purchase orders
may be cancelable without significant penalty or subject to price
renegotiations, changes in unit quantities or delivery schedules to reflect
changes in customers' requirements or manufacturing availability. Consequently,
the Company does not believe that backlog is a reliable indicator of future
sales.

SEGMENTS

        Trident operates in the videographics and audio segments as described
above.

EMPLOYEES

        As of June 30, 1999, the Company had 348 full time employees, including
237 in research and development, 40 in product testing, quality assurance and
operations functions, 47 in marketing and sales and 24 in finance, human
resources, and administration. Competition for qualified personnel in the
semiconductor, software and the PC industry in general is intense in Silicon
Valley where the Company is located. The Company's future success will depend in
great part on its ability to continue to attract, retain and motivate highly
qualified technical, marketing, engineering and management personnel. The
Company's employees are not represented by any collective bargaining agreements,
and the Company has never experienced a work stoppage. The Company believes that
its employee relations are good.

ITEM 2. PROPERTIES

        The Company leases a building of approximately 63,000 square feet on
2450 Walsh Avenue in Santa Clara, California, pursuant to a lease which expires
in June 2001. This building is used as the Company's headquarters and includes
development, marketing and sales, and administrative offices. The Company also
leases a 5,400 square foot research and development facility in Chandler,
Arizona. The Company leases office space for a sales office in Houston, Texas.
This sales office totals approximately 500 square feet. Other Company leases
include a 10,000 square foot office in Kowloon, Hong Kong, China, for the Hong
Kong branch office of the Cayman Islands subsidiary, an 8,000 square foot sales
office in Taipei, Taiwan, a 32,000 square foot research and development facility
in Hsinchu, Taiwan, and an 11,000 square foot research and development facility
in Shanghai, China.

ITEM 3. LEGAL PROCEEDINGS

        On December 14, 1998, NeoMagic Corporation (NASDAQ: NMGC), filed suit in
the United States District Court for the District of Delaware against the
Company. The suit alleges that the Company's embedded DRAM graphics accelerators
infringe certain patents held by NeoMagic Corporation. The Company intends to
defend vigorously the litigation which was filed against it, and the Company
will take every step possible to protect the interests of its customers and
shareholders. On January 25, 1999 the Company filed a counter claim in the
United States District Court for the District of Delaware against NeoMagic
Corporation. The counter claim alleges an attempted monopolization in violation
of the antitrust laws, arising from Neomagic's patent infringement filing
against the Company. On March 25, 1999 NeoMagic Corporation filed a motion for
summary judgement requesting that the Company's counter claim be dismissed. That
motion has not been ruled on. The case is currently set for trial on March 27,
2000.

        In 1998 and 1999 Trident Microsystems, Inc. and VIA Technologies, Inc.
entered into written agreements for the joint development of integrated 3D
graphics and core logic devices for notebook and desktop personal computers. On
July 22, 1999, Trident Microsystems, Inc. and Trident Technologies, Inc. filed a
lawsuit against VIA Technologies, Inc., among other defendants, in the United
States District Court for the Northern District of California. On July 30, 1999,
Trident filed a first amended complaint alleging patent infringement, copyright
infringement, breach of contract, fraud, misappropriation of trade secrets,
breach of fiduciary duty, specific performance, breach of confidence, inducement
of breach of contract, intentional interference with economic relations,
recission and unfair competition. Trident's complaint requests actual damages
sustained by Trident, which are yet to be determined, as well as $200,000,000 in
punitive damages. On August 23, 1999, VIA Technologies, Inc. filed an answer and
counterclaim against Trident Microsystems, Inc., Trident Technologies, Inc. and
Frank Lin seeking a declaratory judgment on Trident's patent and copyright
infringement claims, damages for breach of contract, intentional interference
with contractual relations, intentional interference with prospective economic
relations, misappropriation of trade secrets and unfair competition.

        Due to the fast pace of the PC graphics industry and in order to protect
its intellectual property, on August 11, 1999, Trident Microsystems, Inc. and
Trident Technologies, Inc. filed a motion for preliminary injunction seeking to
prevent the shipment of any VIA products, including but not limited to any
products containing Trident's proprietary software technology. On August 31,
1999, VIA Technologies, Inc. filed its opposition and a counter-motion for a
preliminary injunction seeking to force Trident to provide software drivers and
software support to VIA Technologies, Inc.'s customers. A hearing on these
motions has been continued pending settlement discussions between the parties.

        In July of 1999 Trident filed a Declaratory Judgement action in the
Federal District Court of Delaware against Real 3D Corporation seeking a ruling
by the court which would declare invalid and/or not infringed certain Real 3D
patents being asserted against major Trident notebook PC customers. This filing
of a Declaratory Judgement action follows a complaint filed by Real 3D against a
number of other graphics companies for alleged infringement of three Real 3D
patents which relate to graphics acceleration technology. Real 3D has also
asserted these patents against major OEM PC manufacturers. Currently Trident is
not a party to that litigation.

        Statements regarding the possible outcome of litigation and the
Company's actions are forward looking statements and actual outcomes could vary
based upon future developments on the litigation.

</TABLE>


Net Sales

        Net sales in fiscal 1999 decreased to $89.3 million, or 21%, from $113.0
million reported in fiscal 1998. The decrease in net sales was primarily due to
decreases in unit volume shipments of approximately 30% of graphical user
interface (GUI) accelerators and graphics controllers and a decline in average
selling prices (ASPs) in the desktop area in fiscal 1999 as compared to fiscal
1998. Sales of portable products of $51.4 million were approximately 58% of the
Company's net sales in fiscal 1999 as compared to $44.9 million or 40% of net
sales in fiscal 1998. Sales of GUI accelerator desktop products were
approximately $33.8 million or 38% of the Company's net sales in fiscal 1999 as
compared to approximately $64.0 million or 57% in fiscal 1998.

        Net sales in fiscal 1998 decreased to $113.0 million, or 36%, from
$177.9 million reported in fiscal 1997. The decrease in net sales was primarily
due to a 26% decline in unit volume shipments and decreases in ASPs for GUI
accelerators and graphics controllers in fiscal 1998 as compared to fiscal 1997.
Sales of portable products of $44.9 million were approximately 40% of the
Company's net sales in fiscal 1998 as compared to $65.8 million or 37% of net
sales in fiscal 1997. Sales of GUI accelerator desktop products were
approximately $64.0 million or 57% of the Company's net sales in fiscal 1998 as
compared to approximately $92.5 million or 52% in fiscal 1997.

         The Company has made a major effort to design products to fill the
needs of leading PC systems manufacturers as well as the needs of adapter card
manufacturers. Sales to leading PC systems manufacturers represented
approximately 26% of net sales for fiscal 1999, an increase from 25% in fiscal
1998, and a decrease from 41% in fiscal 1997. Sales to Asian customers,
primarily in Hong Kong, Taiwan, Korea and Japan, accounted for 73%, 84% and 74%
of net sales in fiscal 1999, 1998, and 1997, respectively. Sales to two
customers, Fujitsu and Innoquest, accounted for approximately 13% and 12% of net
sales for fiscal 1999, respectively. Sales to two customers, Union Computer and
Fujitsu, accounted for approximately 15% and 11% of net sales for fiscal 1998,
respectively, and sales to three customers, IBM, Union Computer, and Jaton
Corporation accounted for approximately 21%, 12%, and 11% of net sales for
fiscal 1997, respectively. Substantially all of the sales transactions were
denominated in U.S. dollars during all periods. The Company derives a
significant portion of its revenues from sales to distributors. Sales to
distributors represented 12% and 17% of net sales during the twelve months ended
June 30, 1999 and 1998, respectively. During the first half of fiscal year 1998
the Company experienced higher than usual returns resulting from certain
distributors adjusting their inventory mix and levels.

        The Company plans to develop new and higher-performance GUI
accelerators, graphics controllers and multimedia products to sell to existing
customers as well as new customers in Asia, North America and Europe. The
Company's future success depends upon its successful introduction of these and
other new products on a regular and timely basis and upon those products meeting
customer requirements. There can be no assurance that the Company will be able
to complete the development of new products or to commence shipments of new
products in a timely manner, or that product specifications will not change
during the development period. In addition, even if such new products are
successfully developed and shipped, there can be no assurance that they will be
successful in the marketplace.

Gross Margin

        Trident's gross margin decreased to 32% in fiscal 1999 from 33% in
fiscal 1998. Gross margins were generally lower in fiscal 1999 because of
decreasing prices in desktop computers, and an increase in the cost of embedded
DRAM for portable computers. Trident's gross margin decreased to 33% in fiscal
1998 from 36% in fiscal 1997 due to decreasing prices in the personal computer
industry and a product mix which was more heavily weighted from desktop
computers which have lower margins than portable computer products.

        The Company believes that the prices of high-technology products decline
over time, as competition increases and new, advanced products are introduced.
The Company expects ASPs of existing products to continue to decline, although
the ASPs of the Company's entire product line may remain constant or increase as
a result of introductions of new higher-performance products often with
additional functionality which are planned to be sold at higher prices. The
Company's strategy is to maintain and improve gross margins by (1) developing
new products that have higher margins through its custom design methodology and
migration to new process technology, and (2) reducing manufacturing costs by
large-volume production. There is no assurance that the Company will be able to
develop and introduce new products on a timely basis or that it can reduce
manufacturing costs.

Research and Development

        Research and development expenditures decreased to $26.3 million in
fiscal 1999 from $28.2 million in fiscal 1998, and increased from $22.1 million
in fiscal 1997. Research and development expenditures as a percentage of net
sales were 29%, 25% and 12% in fiscal 1999, 1998 and 1997, respectively. The
decrease in expenditures in fiscal 1999 compared to fiscal 1998 was primarily
due to the Company's cost reduction efforts in fiscal 1999. The increase in
expenditures in fiscal 1998 compared to fiscal 1997 was primarily due to an
increase in spending in multimedia engineering, graphics engineering, the Taiwan
Research and Development Center and the start-up of the Shanghai Research and
Development Center.

Selling, General and Administrative

        Selling, general and administrative expenditures decreased to $16.6
million in fiscal 1999 from $19.0 million in fiscal 1998 and were $21.9 million
in fiscal 1997. Selling, general and administrative expenditures as a percentage
of net sales were 19%, 17% and 12% in fiscal 1999, 1998 and 1997, respectively.
Selling expenditures were $10.9 million in fiscal 1999 as compared to $13.5
million and $14.7 million in fiscal 1998 and 1997, respectively. General and
administrative expenditures were $5.7 million in fiscal 1999 as compared to $5.5
million and $7.2 million in fiscal 1998 and 1997, respectively. Selling costs
have declined in fiscal years 1999 and 1998 due to the slow-down in personal
computer sales and reductions in marketing personnel. General and administrative
expenditures were higher in fiscal 1999 than in fiscal 1998 primarily due to an
increase in legal services. General and administrative expenditures were lower
in fiscal 1998 than in fiscal 1997 primarily due to reductions in bonus
expenses, personnel, and consulting services. As a result of the Company's cost
reduction efforts, the Company expects selling, general and administrative
expenditures to remain at or below the levels for fiscal 1999 during fiscal
2000.

Interest Income, Net

        The amount of interest income earned by the Company varies directly with
the amount of its cash, cash equivalents, short-term investments and the
prevailing interest rates. Net interest income decreased to $2.0 million in
fiscal 1999 from $2.4 million in fiscal 1998 due to lower cash balances in
higher yielding short-term investments. Net interest income increased to $2.4
million in fiscal 1998 from $2.0 million in fiscal 1997 due to cash investments
being held in higher yielding certificates of deposit.

Provision for Income Taxes

        No provision for income tax was taken in fiscal year 1999 due to the
Company's loss situation. As a percentage of income before income taxes, the
provision (benefit) for income tax was (28)% for fiscal year 1998, and 32% for
fiscal years 1997. Based on a number of factors, as of June 30, 1999 the Company
has provided a full valuation allowance. These factors include primarily the
inability to carryback tax attributes to prior federal tax returns as well as
state returns, recent operating losses incurred by the Company, and the fact
that the market in which the Company competes is intensely competitive and
characterized by rapidly changing technology.

Factors That May Affect Our Results

TRIDENT HAS A HISTORY OF LOSSES, EXPECTS FUTURE LOSSES AND CANNOT ASSURE YOU
THAT IT WILL ACHIEVE PROFITABILITY

        We have experienced operating loses in the years ended June 30, 1998 and
1999 and expect to report operating losses for the next several quarters. We
cannot accurately predict when we will achieve profitability. Future performance
will substantially depend upon numerous factors, such as:

        - timely introducing new products and product enhancements to the
          marketplace;
        - whether customers successfully incorporate our technologies into end
          products with high levels of customer acceptance;
        - fluctuating price levels for our products; and
        - funding increased levels of research and development.

        We anticipate that we will incur significant sales and marketing,
product development and general and administrative expenses and, as a result, we
will need to generate significantly higher revenue to achieve and sustain
profitability. Trident's management is diligently trying to control operating
expenses to enable Trident to achieve profitability. However, there is no
guarantee that management's efforts will be successful.


                                       20
<PAGE>   21

A NUMBER OF FACTORS COULD CONTINUE TO CAUSE TRIDENT'S QUARTERLY FINANCIAL
RESULTS TO SIGNIFICANTLY FLUCTUATE

        We plan to tightly control our operating expenses to expand our sales
and marketing activities, broaden our customer support capabilities, develop new
distribution channels and fund increased levels of research and development.

        Our quarterly revenue and operating results have varied significantly in
the past and may fluctuate significantly in the future due to a number of
factors including:

        - fluctuations in demand for our products, including seasonality;
        - unexpected product returns or the cancellation or rescheduling of
          significant orders;
        - our ability to develop, introduce, ship and support new products and
          product enhancements and manage product transitions;
        - announcements and new product introductions by our competitors;
        - our ability to achieve required cost reductions;
        - our ability to attain and maintain production volumes and quality
          levels for our products;
        - delayed new product introductions;
        - unfavorable responses to new products;
        - adverse economic conditions, particularly in Asia;
        - the mix of products sold and the mix of distribution channels through
          which they are sold; and
        - availability of foundry and assembly capacities.

IF A KEY DISTRIBUTOR OR OTHER SIGNIFICANT CUSTOMER CANCELS OR DELAYS A LARGE
PURCHASE, TRIDENT'S REVENUES MAY DECLINE AND THE PRICE OF ITS STOCK MAY FALL

        To date, a limited number of distributors and customers have accounted
for a significant portion of our revenue. If any of our large distributors or
customers stop or delay purchases, our revenue and profitability would be
adversely affected. Although our largest customers may vary from
period-to-period, we anticipate that our operating results for any given period
will continue to depend to a significant extent on large orders from a small
number of customers, particularly in light of the high sales price per unit of
our products and the length of our sales cycles.

        While our financial performance depends on large orders from a few key
distributors and other significant customers, we do not have binding commitments
from any of them. For example:

        - our customers can stop purchasing and our distributors can stop
          marketing our products at any time;

        - our distributor agreements generally are not exclusive with no
          obligation of the distributor to renew the agreements; and

        - our distributor agreements generally do not require minimum purchases.

        We have established a reserve program which, under specified conditions,
enables distributors to return products to us. The amount of potential product
returns is estimated and provided for in the period of the sale. Actual returns
could differ from our estimates.

TRIDENT DEPENDS UPON INTERNATIONAL SALES FOR MUCH OF ITS REVENUE AND TRIDENT'S
ABILITY TO SUSTAIN AND INCREASE ITS INTERNATIONAL SALES DEPENDS ON SUCCESSFULLY
EXPANDING ITS INTERNATIONAL OPERATIONS

        Because our distributors sell our products worldwide, changes in the
global graphics marketplace, such as the shift in market share from Asian clone
makers to leading North American PC systems manufacturers, have affected and
will continue to affect our operating results. Our revenues have been and are
expected to be generated primarily from Asian customers, particularly those of
Taiwan and Hong Kong. Additionally, our ability to grow


                                       21
<PAGE>   22

will depend in part on the expansion of international sales and operations which
have and are expected to constitute a significant portion of our sales. The
failure of our distributors to sell our products internationally would limit our
ability to sustain and grow our revenue. In addition, there are a number of
risks arising from our international business, including:

        - longer accounts receivable collection cycles;
        - difficulties in managing operations across disparate geographic areas;
        - difficulties associated with enforcing agreements through foreign
          legal systems;
        - import or export licensing requirements;
        - potential adverse tax consequences; and
        - unexpected changes in regulatory requirements.

Our international sales currently are U.S. dollar-denominated. As a result, an
increase in the value of the U.S. dollar relative to foreign currencies could
make our products less competitive in international markets.

TRIDENT EXPECTS THE AVERAGE SELLING PRICES OF ITS PRODUCTS TO DECREASE RAPIDLY
WHICH MAY REDUCE GROSS MARGINS OR REVENUE

The graphics controller industry has experienced rapid erosion of average
selling prices due to a number of factors, including competitive pricing
pressures and rapid technological change. We may experience substantial
period-to-period fluctuations in future operating results due to the erosion of
our average selling prices. We anticipate that the average selling prices of
desktop computers will decrease in the future, while the cost of embedded DRAM
for portable computers may increase, in response to competitive pricing
pressures, increased sales discounts, new product introductions by us or our
competitors or other factors. Therefore, to maintain our gross margins, we must
develop and introduce on a timely basis new products and product enhancements
and continually reduce our product costs. Our failure to do so would cause our
revenue and gross margins to decline, which could materially adversely affect
our operating results and cause the price of our common stock to decline.

INTENSE COMPETITION IN THE MARKET FOR GRAPHICS CONTROLLERS COULD CAUSE TRIDENT
TO EXPERIENCE ADDITIONAL ADVERSE FLUCTUATIONS IN ITS OPERATING RESULTS

        The market for graphics controllers is intensely competitive. Many of
our current and potential competitors in both graphics and audio have longer
operating histories and substantially greater financial, technical, sales,
marketing and other resources, as well as greater name recognition and market
share than we do. These competitors may have developed or could in the future
develop new technologies that compete with our products or even render our
products obsolete.

        To remain competitive, we believe we must, among other things, invest
significant resources in developing new products, including products for new
markets, increasing the ability of our products to integrate various functions
and enhancing quality product performance. If we fail to do so, our products may
not compete favorably with those of our competitors and our revenue and future
profitability could be materially adversely affected.

IF TRIDENT'S PRODUCTS CONTAIN UNDETECTED DEFECTS, TRIDENT COULD INCUR
SIGNIFICANT UNEXPECTED EXPENSES AND LOST SALES

        Although we establish and implement test specifications, impose quality
standards upon our suppliers and perform separate application-based
compatibility and system testing, our products may contain undetected defects.
We have experienced such errors in the past and we expect that such errors will
be found from time to time in new or enhanced products after commencement of
commercial shipments. These problems may materially adversely affect our
business by causing us to incur significant warranty and repair costs, diverting
the attention of our engineering personnel from our product development efforts
and causing significant customer relations problems.


                                       22
<PAGE>   23

TRIDENT NEEDS TO EXPAND ITS NETWORK OF MANUFACTURING OPERATIONS AND DEPENDS ON
INDEPENDENT FOUNDRIES FOR SUBSTANTIALLY ALL OF ITS MANUFACTURING REQUIREMENTS

        If the demand for our products grows, we will need to increase our
material purchases, contract manufacturing capacity and internal test and
quality functions. Any disruptions in product flow could limit our revenue,
adversely affect our competitive position and reputation and result in
additional costs or cancellation of orders under agreements with our customers.

        We currently rely on a limited number of third-party foundries to
manufacture our products either in finished form or wafer form. Generally, these
foundries are not obligated to manufacture our products for a fixed period or a
specific quantity at a predetermined price. If a foundry terminates its
relationship with us or we encounter shortages and delays in obtaining
components, our ability to meet customer orders could be materially adversely
affected.

        We have experienced a delay in product shipments from a contract
manufacturer in the past, which in turn delayed product shipments to our
customers. Such delays often force us to purchase at a higher per unit product
cost from other foundries or to pay expediting charges so that we can obtain the
required supply in a timely manner. We may in the future experience delays in
shipments from foundries or other problems, such as inferior quality and
insufficient quantity of product, any of which could materially adversely affect
our business and operating results. There can be no assurance that we will
effectively manage our foundry relationships or that these manufacturers will
meet our future requirements for timely delivery of products of sufficient
quality and quantity. The inability of our contract manufacturers to provide us
with adequate supplies of high-quality products would cause a delay in our
ability to fulfill orders while we obtain a replacement manufacturer and would
have a material adverse effect on our business, operating results and financial
condition.

THE UNSTABLE PUBLIC MARKET COULD CAUSE TRIDENT'S STOCK PRICE TO FALL

        The market price of our common stock has been, and may continue to be,
extremely volatile. Factors such as new product announcements by Trident or our
competitors, quarterly fluctuations in our operating results and unfavorable
conditions in the graphics controller market may have a significant impact on
the market price of our common stock. These conditions, as well as factors that
generally affect the market for stocks of high-technology companies, could cause
the price of Trident's stock to fluctuate substantially over short periods.

TRIDENT'S EXCHANGE OF UICC SHARES FOR UMC SHARES MAY POSE SOME ECONOMIC RISKS

        We expect to receive approximately 46.5 million shares of UMC stock in
exchange for our shares of UICC by the end of 1999. This exchange may provide us
with an improved balance sheet and additional capital but may be subject to
resale restrictions and have a fair market value which fluctuates dramatically.
We have not received the UMC shares nor have we determined whether or when we
will sell the UMC shares or the sales price if the sale occurs.

IF TRIDENT OR ITS KEY DISTRIBUTORS AND CUSTOMERS FAIL TO BE YEAR 2000 COMPLIANT,
TRIDENT'S BUSINESS MAY BE SEVERELY DISRUPTED AND ITS REVENUES MAY DECLINE

        The year 2000 computer issue creates a risk for us. If systems do not
correctly recognize date information when the year changes to 2000, there could
be an adverse impact on our operations. The risk exists in four areas:

        - potential warranty or other claims from our customers;
        - systems we use to run our business;
        - systems used by our distributors; and
        - the potential reduced spending by other companies on networking
          solutions as a result of significant


                                       23
<PAGE>   24

          information systems spending on year 2000 remediation.

        We are currently evaluating our exposure in all of these areas.

        We are in the process of conducting an inventory and evaluation of the
information systems used to run our business. Systems which are identified as
non-compliant will be upgraded or replaced. For the year 2000 non-compliance
issues identified to date, the cost of remediation is not expected to be
material to our operating results. However, if implementation of replacement
systems is delayed, or if significant new non-compliance issues are identified,
our operating results or financial condition could be materially adversely
affected.

        We intend to contact our critical distributors to determine that the
distributors' operations and the products and services they provide are year
2000 compliant. Where practicable, we will attempt to mitigate our risks with
respect to the failure of suppliers to be year 2000 ready. However, failures
remain a possibility and could have an adverse impact on our operating results
or financial condition.

        Since all customer situations cannot be anticipated, we may see an
increase in warranty and other claims as a result of the year 2000 transition.
In addition, litigation regarding year 2000 compliance issues is expected to
escalate. For these reasons, the impact of customer claims could have a material
adverse impact on our operating results or financial condition.

        Businesses that face year 2000 compliance issues may require significant
hardware and software upgrades or modifications to their computer systems and
applications. These companies may plan to devote a substantial portion of their
information systems' spending to fund such upgrades and modifications and divert
spending away from IC videographics or audio products for the PC market. This
change in customers' spending patterns could materially adversely impact our
business, operating results or financial condition.

LIQUIDITY AND CAPITAL RESOURCES

        As of June 30, 1999, the Company's principal sources of liquidity
included cash and cash equivalents of $32.5 million. Cash used in operating
activities was $1.7 million in fiscal year 1999. Cash used in operating
activities in fiscal year 1998 was $7.7 million. Cash used in operating
activities in 1999 was mainly due to unprofitable operations, increases in
accounts receivable and prepaid expenses, primarily offset by decreases in
inventories and deferred taxes, and increases in accounts payable and accrued
expenses. Cash used in operating activities in fiscal 1998 was mainly due to
unprofitable operations, an increase in inventory, decreases in accounts payable
and accrued expenses, primarily offset by a decrease in accounts receivable.
Capital expenditures in fiscal 1999, 1998 and 1997 were $2.6 million, $3.8
million and $3.5 million, respectively.

        During fiscal years 1999, 1998, and 1997 the Company issued 277,000,
319,000 and 392,000 shares of common stock under its employee stock option and
purchase plans, respectively. These issuances generated cash of $1.0 million,
$2.5 million, and $2.9 million in fiscal 1999, 1998, and 1997, respectively.

        In fiscal year 1998, the Company invested $2.0 million in cash in a
privately-held semiconductor design company for an equity interest of less than
10%. The investment is presented as a long-term investment in the financial
statements.

        In August 1995, the Company entered into a joint venture agreement with
UMC and other venture partners to establish a foundry, UICC. Under the
agreement, the Company invested $49.3 million in the joint venture and the
foundry guarantees to Trident a certain percentage of the foundry's total wafer
supply. On October 3, 1997, a fire at UICC's fabrication plant in Hsin Chu,
Taiwan, completely destroyed its fabrication equipment. The fabrication plant,
and the destroyed equipment, was insured. In June 1999 the Company announced
that it has received confirmation from UMC that, subject to the approval of the
UMC shareholders and the Taiwan government, the UICC joint venture will be
consolidated with UMC by the end of 1999. Trident expects to receive
approximately 46.5 million shares of UMC stock in the consolidation. These
shares represent about 0.5% of the outstanding stock of UMC. As the
consolidation is subject to UMC shareholder approval, no assurance can be


                                       24
<PAGE>   25

given as to whether such shares will be received. The Company has not determined
whether or when it will sell such shares and the shares may be subject to
trading or other restrictions. Following the consolidation, Trident will
continue to have a guaranteed wafer supply from UMC approximately the same in
quantity as it had with UICC. At June 30, 1999, the Company held a 7.25% equity
ownership in UICC.

        The Company's investment in the UICC joint venture is intended to secure
capacity so that it can meet expected increased demand, should it occur.
However, there are certain risks associated with the transaction including the
Company's ability, together with its partners, to fully utilize the capacity of
UICC. The Company will continue to consider transactions to secure additional
foundry capacity as circumstances warrant.

        The agreement with UMC has utilized a significant amount of Trident's
available funds; however, the Company believes its current resources are
sufficient to meet its needs for at least the next twelve months. The Company
regularly considers transactions to finance its activities, including debt and
equity offerings and new credit facilities or other financing transactions. The
Company believes its current reserves are adequate.

        In April, 1998, the Company's Board of Directors approved a $20 million
stock repurchase program over the next twelve months. During fiscal year 1999,
161,000 shares of common stock were repurchased for $0.9 million under this
Plan. During fiscal year 1998, 274,500 shares of common stock were repurchased
for $2.1 million under this Plan. During fiscal year 1997, the Company
repurchased 100,000 shares of common stock for $1.1 million. The Company's cash
reserves may decline as a result of its future use, if any, of the repurchase
program.

YEAR 2000

        Some computers, software, and other equipment include computer code in
which calendar year data is abbreviated to only two digits. As a result of this
design decision, some of these systems could fail to operate or fail to produce
correct results if "00" is interpreted to mean 1900, rather than 2000. These
problems are widely expected to increase in frequency and severity as the year
2000 approaches, and are referred to in this report as "Year 2000 issues."

        The Company has a Year 2000 project designed to identify and assess the
risks associated with its information systems, products, operations and
infrastructure, and suppliers that are not Year 2000 compliant and to develop,
implement, and test remediation and contingency plans to mitigate these risks.
The project is composed of four phases: (1) identification of risks, (2)
assessment of risks, (3) development of remediation and contingency plans, and
(4) implementation and testing.

        Information systems. In 1997, the Company undertook a project to upgrade
all its information systems to Year 2000 compliance. The Company is in its final
implementation and testing phase of its information systems for Year 2000
compliance. This phase is expected to be completed by the end of September 1999.

        Products. The Company has assessed the capabilities of all of its
products sold to customers. Based on the assessments made to date, none of the
Company's products are affected by Year 2000 issues.

        Operations and Infrastructure. Office equipment and other items used in
the operations and facilities of the Company are currently in the final
implementation and testing phase for Year 2000 compliance. This phase is
expected to be completed by the end of September 1999.

        Suppliers. The Company has evaluated its supplier base to determine
whether Year 2000 issues affecting suppliers will adversely impact the Company's
operations. The Company has contacted all of its suppliers to assess their Year
2000 readiness and will continue to monitor the progress of its key suppliers.
The Company has assessed its key suppliers for Year 2000 readiness and has not
found any Year 2000 issues from suppliers which would adversely impact the
Company's operations.


                                       25
<PAGE>   26

        General and Risk Factors. The Company believes that its greatest
potential risks are associated with its information systems and systems embedded
in its operations and infrastructure. The Company is in the final stages of
implementation for all its information systems, operations and infrastructure,
but cannot predict whether significant problems will be identified. The Company
has not yet determined the extent of contingency planning that may be required.
Based on the status of the assessment made and remediation plans developed to
date, the Company is not in a position to state the total cost of remediation of
all Year 2000 issues. Costs identified to date are expected to be not less than
$100,000.

        Most likely consequences of Year 2000 issues. We expect to identify and
resolve all Year 2000 issues that could materially adversely affect our business
operations. However, we believe that it is not possible to determine with
complete certainty that all Year 2000 issues affecting us have been identified
or corrected. The number of devices that could be affected and the interactions
among these devices are simply to numerous. In addition, no one can accurately
predict how many Year 2000 issues related failures will occur or the severity,
duration, or financial consequences of these perhaps inevitable failures. As a
result, we believe that the following consequences are possible:

        - a significant number of operational inconveniences and inefficiencies
          for us, our contract manufacturers and our customers that will divert
          management's time and attention and financial and human resources from
          ordinary business activities;

        - several business disputes and claims for pricing adjustments or
          penalties due to Year 2000 issues by our customers, which we believe
          will be resolved in the ordinary course of business; and

        - a few serious business disputes alleging that we failed to comply with
          the terms of contracts or industry standards of performance, some of
          which could result in litigation or contract termination.

Disclaimer. The discussion of our efforts and expectations relating to Year 2000
compliance are forward-looking statements. Our ability to achieve Year 2000
compliance and the level of incremental costs associated therewith, could be
adversely affected by, among other things, the availability and cost of
programming and testing resources, third party suppliers' ability to modify
proprietary software, and unanticipated problems identified in the ongoing
compliance review.

To the Board of Directors and Stockholders of
Trident Microsystems, Inc.

In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of changes in stockholders' equity and of
cash flows present fairly, in all material respects, the financial position of
Trident Microsystems, Inc. and its subsidiaries at June 30, 1999 and 1998, and
the results of their operations and their cash flows for each of the three years
in the period ended June 30, 1999, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards, which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        THE COMPANY

        Trident Microsystems, Inc. (the "Company") designs, develops and markets
        videographics and multimedia integrated circuits for the desktop and
        portable PC market.

        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        Basis of Presentation. The consolidated financial statements include the
        accounts of the Company and its subsidiaries after elimination of all
        significant intercompany accounts and transactions. The preparation of
        financial statements in accordance with generally accepted accounting
        principles requires management to make estimates and assumptions that
        affect the reported amounts; actual results could differ from those
        estimates.

        Cash Equivalents and Short-Term Investments. Cash equivalents consist of
        highly liquid investments in money market accounts and certificates of
        deposits purchased with an original maturity of 90 days or less from the
        date of purchase. Short-term investments were comprised of certificates
        of deposits with contractual maturities of less than one year and have
        been classified "available-for-sale."

        Inventories. Inventories are stated principally at standard cost
        adjusted to approximate the lower of cost (first-in, first-out method)
        or market (net realizable value).

        Property and Equipment. Property and equipment are stated at cost.
        Depreciation is computed using the straight-line method over the
        estimated useful lives which range from three to seven years.
        Amortization of leasehold improvements is computed using the
        straight-line method over the shorter of the estimated life of the
        assets or the extended lease term.

        Investments. Equity investment of less than 20% wherein the Company does
        not have the ability to exert significant influence are accounted for
        using the cost method.

        Revenue Recognition. Revenue from product sales is recognized upon
        shipment. Provision is made for expected sales returns and allowances
        when revenue is recognized. The Company has limited control over the
        extent to which products sold to distributors are sold through to end
        users. Accordingly, a portion of the Company's sales may from time to
        time result in increased inventory at its distributors. The Company
        provides reserves for returns and allowances for distributor
        inventories. These reserves are based on the Company's estimates of
        inventory held by its distributors and the expected sell through of its
        products by its distributors. Actual results could differ from these
        estimates.

        Software Development Costs. To date, the period between achieving
        technological feasibility and the general availability of such software
        has been short and software development costs qualifying for
        capitalization have been insignificant. Accordingly, the Company has not
        capitalized any software development costs.

        Income Taxes. The Company accounts for income taxes using the asset and
        liability method, under which the expected future tax consequences of
        temporary differences between the book and tax bases of assets and
        liabilities are recognized as deferred tax assets and liabilities. The
        Company does not record a deferred tax provision on unremitted earnings
        of foreign subsidiaries to the extent that such earnings are considered
        permanently invested.

        Net Income (loss) per Share. Basic net income (loss) per share is
        computed by dividing net income (loss) available to common shareholders
        by the weighted average number of common shares outstanding during the
        period. Diluted net income per share is calculated using the weighted
        average number of outstanding shares of common stock plus dilutive
        potential common stock shares. Potential common stock shares consist of
        common stock options, computed using the treasury stock method based on
        the average stock price for the period.

        Foreign Currency Transactions. The functional currency of the Company's
        operations in all countries is the U.S. dollar. Sales and purchase
        transactions are generally denominated in U.S. dollars. Foreign
        transaction gains and losses were not material for each period
        presented.

        Stock-based Compensation. The Company accounts for stock-based employee
        compensation arrangements in accordance with provisions of Accounting
        Principles Board Opinions ("APB") No. 25, "Accounting for Stock Issued
        to Employees" and complies with the disclosure provisions of Statements
        of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
        Stock-Based Compensation. " Under APB No. 25, compensation cost is
        generally recognized based on the difference, if any, between the quoted
        market price of the Company's stock on the date of grant and the amount
        an employee must pay to acquire the stock.

        Comprehensive income. Effective July 1, 1998, the Company adopted the
        provision of SFAS No. 130, "Reporting Comprehensive Income." This
        statement requires companies to classify items of other comprehensive
        income by their components in the financial statements and display the
        accumulated balance of other comprehensive income separately from
        retained earnings in the equity section of a statement of financial
        position. Foreign currency translation and unrealized gains and losses
        on short-term investments are comprehensive income items applicable to
        the Company. To date, the Company has not had any material transactions
        that are required to be reported in comprehensive income.

        New Accounting Pronouncements. In June 1998, the Financial Accounting
        Standards Board issued SFAS No. 133, "Accounting for Derivative
        Instruments and Hedging Activities." SFAS No. 133 establishes standards
        for accounting and reporting on derivative. SFAS No. 133 requires that
        all derivative instruments be recognized in the balance sheet as either
        assets or liabilities and measured at fair value. Furthermore, SFAS No.
        133 requires current recognition in earnings of changes in the fair
        value of derivative instruments depending on the intended use of the
        derivative and the resulting designation. The Company expects that its
        adoption of SFAS No. 133, which will become effective in fiscal year
        2001, will not have a material effect on the Company's financial
        statements.

        During fiscal years 1999 and 1998, all options outstanding were
        anti-dilutive due to the net loss incurred for the year and were
        accordingly excluded from the net loss per share calculation. During
        fiscal 1997, options to purchase 260,301 shares of common stock were
        antidilutive and excluded from the dilutive net income per share
        calculations because the options' exercise price was greater than the
        average market price of the common shares.

4. AGREEMENTS WITH WAFER FOUNDRIES

        Investment in Joint Venture. In August 1995, the Company entered into a
        joint venture agreement with United Microelectronics Corporation ("UMC")
        and other venture partners to establish a foundry, United Integrated
        Circuits Corporation ("UICC"). Under the agreement, the Company invested
        $49.3 million in the joint venture and the foundry guaranteed to Trident
        a certain percentage of the foundry's total wafer supply. In October
        1997, a fire at UICC's fabrication plant in Hsin Chu, Taiwan completely
        destroyed its fabrication equipment. The fabrication plant and the
        destroyed equipment were insured. In June 1999 the Company announced
        that it has received confirmation from UMC that, subject to the approval
        of UMC shareholders and the Taiwan government, the UICC joint venture
        will be consolidated with UMC by the end of 1999. Trident expects to
        receive approximately 46.5 million shares of UMC stock in the
        consolidation. These shares represent about 0.5% of the outstanding
        stock of UMC. As the consolidation is subject to UMC shareholder
        approval, no assurance can be given as to whether such shares will be
        received. The Company has not determined whether or when it will sell
        such shares and the shares may be subject to trading or other
        restrictions. Following the consolidation, Trident will continue to have
        a

        guaranteed wafer supply from UMC approximately the same in quantity as
        it had with UICC. At June 30, 1999, the Company held a 7.25% equity
        ownership in UICC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
-------------------------------------------------------------------------------

        Based on a number of factors, as of June 30, 1999, the Company has
        provided a full valuation allowance for deferred tax assets due to the
        uncertainty regarding their realization. These factors include primarily
        recent operating losses incurred by the Company, the fact that the
        market in which the Company competes is intensely competitive and
        characterized by rapidly changing technology, and the inability to
        carryback tax attributes to prior year Federal and State returns.

        The reconciliation of the income tax provisions computed at the United
        States federal statutory rate to the effective tax rate for the recorded
        provision for income taxes is as follows:

        The Company has not provided for U.S. federal income and foreign
        withholding taxes on approximately $11 million of a non-U.S.
        subsidiary's undistributed earnings as of June 30, 1999, because such
        earnings are intended to be reinvested outside the U.S. indefinitely.

6. STOCK-BASED COMPENSATION

        Stock Purchase Plans. In October 1998, the Board of Directors of the
        Company (the "Board") adopted the 1998 Employee Stock Purchase Plan
        under which 500,000 shares of the Company's common stock may be issued.
        This plan replaced the 1992 Employee Stock Purchase Plan which was
        terminated on October 30, 1998. Shares are to be purchased from payroll
        deductions; employees of the Company who are based outside the United
        States may participate by making direct contributions to the Company for
        the purchase of stock. Such payroll deductions or direct contributions
        may not exceed 10% of an employee's compensation. The purchase price per
        share at which the shares of the Company's common stock are sold in an
        offering generally will be equal to 85% of the lesser of the fair market
        value of the common stock on the first or the last day of the offering.
        During fiscal year 1999, 108,000 shares were issued under the 1998
        Employee Stock Purchase Plan. During fiscal years 1999 and 1998, 144,000
        and 137,000 shares were issued under the 1992 Employee Stock Purchase
        Plan, respectively.

        Stock Options. The Company grants nonstatutory and incentive stock
        options to key employees, directors and consultants. At June 30, 1999,
        shares of common stock reserved for issuance upon exercise of the stock
        options aggregated 7,055,000. Stock options are granted at prices
        determined by the Board. Nonstatutory and incentive stock options may be
        granted at prices not less than 85% of the fair market value and at not
        less than fair market value, respectively, at the date of grant. Options
        generally become exercisable one year after date of grant and vest over
        a maximum period of five years following the date of grant.

        Weighted average fair value of options granted were $2.40, $5.78 and
        $5.34 for fiscal years 1999, 1998 and 1997, respectively.

        Stock Repurchases. On April 22, 1998, the Board authorized the Company
        to repurchase up to $20,000,000 of its own common stock at prevailing
        prices over the next 12 months. During fiscal years 1999 and 1998,
        161,000 and 274,500 shares have been repurchased for $940,000 and
        $2,100,000 in cash, respectively. On April 22, 1997, the Board
        authorized the Company to repurchase up to 600,000 shares of its own
        common stock under certain conditions at prevailing market prices
        through October 1997. In April 1997, the Company repurchased 100,000
        shares for $1,085,000 in cash. Shares repurchased are being held as
        treasury stock until reissued to the Company's stock option and stock
        purchase plans or other benefit plans the Company may adopt in the
        future or for other corporate purposes.

7. PREFERRED RIGHTS AGREEMENT

        On July 24, 1998, the Board adopted a Preferred Shares Rights Agreement
        ("Agreement") and pursuant to the Agreement authorized and declared a
        dividend of one preferred share purchase right ("Right") for each common
        share outstanding of the Company on August 14, 1998. The Rights are
        designed to protect and maximize the value of the outstanding equity
        interests in the Company in the event of an unsolicited attempt by an
        acquirer to take over the Company, in a manner or terms not approved by
        the Board. Each Right becomes exercisable to purchase one-hundredth of a
        share of Series A Preferred Stock of the Company at an exercise price of
        $50.00 and expire on July 23, 2008. The Company may redeem the Rights at
        a price of $0.001 per Right.

8. RELATED PARTY TRANSACTIONS

        During the year ended June 30, 1997, the Company sold products with
        revenues of $14,805,000 to a stockholder of the Company and affiliates
        of that stockholder. The Company believes that the terms of the
        transactions with those customers were no less favorable to the Company
        than those offered to entities unrelated to the Company.

9. GEOGRAPHIC SEGMENT INFORMATION

        Effective July 1, 1998, the Company adopted SFAS No. 131, "Disclosures
        about Segments of an Enterprise and Related Information." This statement
        requires enterprises to report information about operating segments in
        annual financial statements and selected information about reportable
        segments in interim financial reports. It also establishes standards for
        related disclosures about products, geographic areas and major
        customers. The Company has one reportable segment. The following is a
        summary of the Company's geographic operations:

</TABLE>

        Product sales are attributed to countries based on delivery locations.
        Long-lived assets comprise property and equipment.

        The Company sells principally to multinational original equipment
        manufacturers, many of whom have manufacturing facilities in Asia, and
        to adapter card manufacturers primarily located in Asia. Sales to
        customers in Asia totaled 73%, 84% and 74% for fiscal years 1999, 1998
        and 1997, respectively. Export sales to third party customers outside of
        the United States totaled $193,000, $240,000, and $1,553,000,
        respectively.

10. COMMITMENTS AND CONCENTRATION OF SALES AND CREDIT RISK

        Capital Leases. In June 1997, the Company entered into a capital lease
        agreement with an equipment maker for research equipment in the amount
        of $1,102,000. In April of 1999, $109,000 of additional lease equipment
        was acquired. At June 30, 1999, leased capital assets and related
        accumulated depreciation included in property, plant and equipment were
        $1,211,000 and $722,000 respectively, and total capital lease
        obligations were $466,000. Total future minimum lease payments under the
        capital lease at June 30, 1999 are $422,000, $41,000, and $30,000 in
        fiscal years 2000, 2001 and 2002, respectively.

        Building Leases. The Company leases facilities under noncancelable
        operating lease agreements, which expire at various dates through 2002.
        Rental expense for the years ended June 30, 1999, 1998 and 1997 was
        $2,406,000, $2,127,000 and $1,656,000, respectively. Total future
        minimum lease payments under operating leases at June 30, 1999 were
        $2,342,000, $1,667,000 and $175,000 in fiscal years 2000, 2001 and 2002,
        respectively.

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

        Concentration of Sales and Credit Risks. Two customers, Fujitsu and
        Innoquest, comprised 13% and 12% of the Company's net sales for the year
        ended June 30, 1999. Two customers, Union Computer and Fujitsu,
        comprised 15% and 11% of the Company's net sales for the year ended June
        30, 1998. Three customers, IBM, Union Computer, and Jaton Corporation
        comprised 21%, 12% and 11%, of the Company's net sales for the year
        ended June 30, 1997.

        Financial instruments that potentially subject the Company to
        significant concentrations of credit risk consist principally of cash
        and cash equivalents, and trade accounts receivable. The Company places
        its cash and cash equivalents primarily in market rate accounts. The
        Company offers credit terms on the sale of its products to certain
        customers. The Company performs ongoing credit evaluations of its
        customers' financial condition and, generally, requires no collateral
        from its customers. The Company maintains an allowance for uncollectible
        accounts receivable based upon the expected collectibility of all
        accounts receivable.

11. LITIGATION

        On December 14, 1998, NeoMagic Corporation ("NeoMagic"), filed a patent
        infringement lawsuit against the Company. The Company believes it has
        meritorious defenses against NeoMagic's action and it intends to defend
        itself vigorously. On July 22, 1999, the Company filed a lawsuit against
        VIA Technologies Inc. ("VIA") for breach of contract, fraud,
        misappropriation of trade secrets, breach of fiduciary duty, specific
        performance, breach of confidence, inducement of breach of contract,
        intentional interference with economic relations, recission and unfair
        competition, and patent infringement and copyright infringement. In
        response to the Company's lawsuit, VIA filed a counter lawsuit against
        the Company. The Company believes it has a valid basis for action
        against VIA and defenses against counterclaim by VIA. However, given the
        nature of litigation and inherent uncertainties associated with
        litigation, management cannot predict with certainty the ultimate
        outcome of these litigations.
