•

•

•

•

•

•

•

unpredictable volume and timing of customer orders, which are not fixed by contract but vary on a

demands and general economic conditions;

condition in future periods. We cannot assure you that we will attain any estimates or maintain profitability or
that the assumptions on which they are based are reliable.

(1)

In 2003 and 2004 we determined that impairment of our intangible assets occurred as a result of a
significant decline in expected net sales from new consumer products such as broadband Internet video
phones, car navigation systems, and Tablet PCs. As the development and market for these products did not
materialize, the forecasted sales and cash flows were significantly reduced.
(2) Write-off of a non-trade related receivable, the collection of which is doubtful.

Exchange Rate Information

We conduct our business primarily in Taiwan and our revenues and expenses are primarily denominated in

NT dollars. This annual report contains translations of NT dollar amounts into U.S. dollar amounts at specific
rates solely for the convenience of the reader. The translations of NT dollar amounts into U.S. dollar amounts in

Risk Factors

Risks Related to Our Business

Because our operating results for any period could be adversely affected by a number of factors and may

therefore fluctuate significantly, our annual and quarterly operating results are difficult to predict.

Although we have been able to generate strong revenue and earnings growth and maintain relatively stable
gross margins and operating margins, we cannot assure you that we will be able to maintain in the future growth
rates and margins similar to those of past periods. A variety of factors may cause our growth rates and margins to
decline, including:

•

•

•

•

•

•

continuing downward pressure on the average selling prices of our products caused by intense
competition in our industry and other reasons;

decreases in demand for multimedia consumer electronics products, including mobile phones, into
which our semiconductor solutions are directly or indirectly incorporated;

our customers’ sales outlook, purchasing patterns and inventory adjustments based on consumer
demands and general economic conditions;

the loss of one or more key customers or the significant reduction, postponement, rescheduling or
cancellation of orders from these customers;

changes in the seasonality of our sales, which generally has a tendency toward increased sales in the
second half of each year;

our ability to develop or acquire, introduce, market and transition to volume production new or
enhanced products and technologies, and in a cost-effective and timely manner;

4

•

•

•

•

•

•

•

•

•

•

changes in the relative sales mix of our products;

the availability and pricing of third party semiconductor foundry, assembly and test capacity and raw
materials, as well as other changes in our cost of finished goods;

the availability, pricing and timeliness of delivery of other components and raw materials used in our
customers’ products;

unpredictable volume and timing of customer orders, which are not fixed by contract but vary on a
purchase order basis;

superior product innovations by our competitors;

the timing of new product announcements or introductions by us or by our competitors;

competitors offering comparable products at cheaper prices;

our ability to scale our operations in response to increasing demand by customers for our new or
existing products;

our ability to timely and accurately predict market requirements and evolving industry trends and to
identify and capitalize upon opportunities in new markets; and

the overall cyclicality of, and changing economic and market conditions in, the semiconductor industry.

The result of these and other factors, as well as our recent rapid growth, makes it difficult for us to assess
our future performance. Our quarterly sales and operating results are difficult to predict and have in the past, and
will likely in the future, fluctuate from quarter to quarter. We could fail to achieve the operating targets that we
have announced, such as revenue growth, gross margin, operating margins, and earnings per ADS. In addition,
our operating results in the future may be below the expectations of public market analysts or investors, which
would likely cause the market price of our ADSs to decline. Any variations in our period-to-period performance
may also cause the market price of our ADSs to fluctuate. Accordingly, you should not rely on the results of any
prior periods as a reliable indicator of our future operating performance.

We depend on a small number of customers for a significant portion of our revenues and a loss of some

of these customers would result in the loss of a significant portion of our revenues.

We have derived a substantial portion of our past revenue from sales to a relatively small number of
customers. As a result, the loss of any significant customer could materially and adversely affect our financial
condition and results of operations. Sales to our five largest customers represented approximately 35%, 40% and
57% of our net revenue in 2006, 2005 and 2004, respectively. We only had one customer in 2006 and 2005 that
accounted for 10% or more of our sales, and three customers in 2004 that accounted for 10% or more of our
sales. The identities of our largest customers and their respective contributions to our net revenue have varied and
will likely continue to vary from period to period.

Sales to our customers may be significantly higher if indirect sales are included with direct sales. In 2006,

Samsung Electronics was our sixth largest customer and accounted for approximately 4% our sales. In 2006,
ATP Electronics and Barun Electronics were our second and seventh largest customers and accounted for
approximately 9% and 4% of our sales, respectively. We believe a substantial portion of our sales to ATP
Electronics and Barun Electronics are included in the products of Samsung Electronics and that such direct and
indirect sales to Samsung Electronics amounted to between 13% and 15% of our net sales. We believe that if our
sales to ATP Electronics and Barun Electronics were included in our sales to Samsung Electronics in 2005 and
2004, such direct and indirect sales to Samsung Electronics would amount to between 10% and 12% and 4% and
5% in the respective years. In 2006, 2005 and 2004, Lexar Media was our ninth, fourth and second largest
customer and accounted for approximately 3%, 7% and 13% of our sales in the respective years. We believe a
substantial portion of our sales to Power Digital Card and Macrotron Systems in 2006, 2005 and 2004 are
included in Lexar Media’s products and that such indirect and direct sales to Lexar Media amounted up to 8% of
our net sales in 2006, up to 18% in 2005 and up to 35% of our net sales in 2004.

5

We expect that we will continue to depend on a relatively limited number of customers for a substantial
portion of our net sales and our ability to maintain good relationships with these customers will be important to
the ongoing success of our business. We cannot assure you that the revenue generated from these customers,
individually or in the aggregate, will reach or exceed historical levels in any future period. Our failure to meet the
demands of these customers could lead to a cancellation or reduction of business from these customers. In
addition, loss, cancellation or reduction of business from, significant changes in scheduled deliveries to, or
decreases in the prices of products sold to, any of these customers could significantly reduce our revenues and
adversely affect our financial condition and operating results. Moreover, any difficulty in collecting outstanding
amounts due from our customers particularly customers who place large orders, would harm our financial
performance. In addition, if our relationships with our largest customers are disrupted for any reason, it could
have a significant impact on our business.

The acquisition of FCI could result in operating difficulties, loss of key personnel and other harmful

consequences.

We do not have significant experience acquiring companies. Although our previous business combination,

which involved the acquisition of SMI USA by Feiya, has been successful, we cannot assure you that our
acquisition of Future Communications IC, Inc., or FCI, on April 30, 2007 will be similarly successful. The
process of integrating FCI may create unforeseen operating difficulties and expenditures. The areas where we
may face risks include:

•

•

•

•

•

implementation or remediation of controls, procedures and policies at FCI;

diversion of management time and focus from operating our business to acquisition integration
challenges;

challenges associated with integrating employees from FCI into our organization such as different
cultures and languages;

integration of FCI’s accounting, management information, human resource and other administrative
systems; and

other unique risks such as currency, economic, political and regulatory risks.

In addition, our success depends in part on the abilities and continued service of each of the current
executives of FCI. We have service agreements in place with certain key FCI senior executives and have
non-compete agreements with these senior FCI executives and other key FCI executives. Our executives at FCI
along with other Silicon Motion executives and employees all benefit from long term employee retention
programs which include participation in our Share-based Compensation Plans. If we are not able to retain the
services of our FCI executives and incur the loss of their services, in the absence of adequate replacements, our
ability to implement our business strategy for FCI and operate the business effectively would be harmed.

We may not be able to sustain our current growth rates, and even if we do maintain them, we are

susceptible to many challenges relating to our growth.

We have experienced significant growth in the scope and complexity of our business. Our net sales grew
from approximately NT$915.1 million in 2003 to approximately NT$2,166.7 million in 2004 to approximately
NT$2,686.5 million in 2005 and to approximately NT$3,460.5 million (US$106.2 million) in 2006. This growth
has placed and will continue to place a strain on our management, personnel, systems and resources. If we are
unable to manage our growth effectively, we may not be able to take advantage of market opportunities, develop
new products, enhance our technological capabilities, satisfy customer requirements, execute on our business
plan or respond to competitive pressures. In particular, the success of our goal to penetrate the MP3 market is
highly contingent on the viability of our strategy and the success of our growth plans. To successfully manage
our growth, we believe we must effectively:

•

hire, train, integrate and manage additional qualified engineers, sales and marketing personnel and
financial and information technology personnel;

6

•

•

•

implement additional and improve existing administrative, financial and operations systems, procedures
and controls;

continue to enhance our manufacturing and customer resource management systems;

continue to expand and upgrade our core semiconductor design and software development capabilities;

• manage multiple relationships with foundries, distributors, suppliers and certain other third parties; and

• manage our financial condition.

Our success also depends largely on our ability to anticipate and respond to expected changes in future
demand for our products. In the event the timing of our expansion does not match market demand, our business
strategy may need to be revised, and there could be delays in our roll-out of new products, which may adversely
affect our growth and future prospects. If we over-expand and demand for our products does not increase as we
may have projected, our financial results will be materially and adversely affected. However, if we do not
expand, and demand for our products increases sharply, our business could be seriously harmed because we may
not be as cost-effective as our competitors due to our inability to take advantage of increased economies of scale.
In addition, we may not be able to satisfy the needs of our current customers or attract new customers, and we
may lose credibility and our relationships with our customers may be negatively affected. Moreover, if we do not
properly allocate our resources in line with future demand for particular products, we may miss changing market
opportunities and our business and financial results could be materially and adversely affected. We cannot assure
you that we will be able to successfully sustain our current growth rate or that we will be able to manage our
growth in the future.

Industry standards and demands in the multimedia consumer electronics market are continuously and

rapidly evolving, and our success depends on our ability to anticipate and meet these changes and trends.

In order to remain competitive in the future, we must ensure that our products meet continuously evolving
industry standards and are compatible with rapidly changing customer requirements. If our products do not keep
pace with evolving industry standards or if our products are not in compliance with prevailing industry standards
for an extended period of time, we could be required to invest significant time, effort and funds to redesign our
products to ensure compatibility with relevant standards. If we are slow to anticipate changing trends and
respond to such charges in a timely manner, we could miss opportunities to capture potential customers and we
could lose our existing market share or existing customers. Currently, our primary products are controllers used
in flash memory storage devices. If new technologies for storing digital media are developed that compete with
flash memory technology or render it obsolete and if we are not able to shift our product offerings accordingly,
demand for our products would likely decline and our business would be materially and adversely affected.

In addition, we may not have sufficient financial resources to fund all of the required research to develop

future innovations and meet changing industry standards. Moreover, even if we have adequate financial
resources, our future innovations may be outpaced by competing innovations. As a result, we may lose customers
and significant sales, and our business and operating results may be materially and adversely affected.

If demand for our products declines in the major end markets that we serve, our selling prices and our

overall sales will decrease.

Demand for our products is affected by a number of factors, including the general demand for the products

in the end markets that we serve and price attractiveness. A significant amount of our sales revenue is derived
from customers who use our microcontrollers in removable and irremovable flash memory storage solutions used
in communications, consumer electronics and computing devices, such as mobile phones, smart phones, digital
cameras, PDAs, MP3 players and notebook and desktop PCs. Any significant decrease in the demand for these
devices may decrease the demand for our semiconductor solutions and may result in a decrease in our revenues
and earnings. A variety of factors, including economic, political and social instability, could contribute to a

7

slowdown in the demand for non-essential communications, consumer electronics and computing devices as
consumers delay purchasing decisions or reduce their discretionary spending. In addition, the historical and
continuing trend of declining average selling prices of communications, consumer electronics and computing
devices places pricing pressure on our semiconductor solutions. As a result, we expect that the average selling
prices for many of our semiconductor solutions will continue to decline over the long term. If we are not able to
introduce higher margin products, reduce our manufacturing costs to offset expected declines in average selling
prices or maintain a high capacity utilization rate, our gross margin will continue to decline, which could have a
material and adverse effect on our financial condition and operating results.

If the semiconductor industry suffers a shortage of flash memory, which is a key component in many of

our customers’ end products, our revenues could be adversely affected.

In 2004 and 2005, some of our customers indicated that they were unable to acquire enough flash memory
to meet all of the anticipated demand for their products. Several manufacturers of flash memory have increased
manufacturing capacity for flash memory since then. However, we cannot assure you that there will continue to
be enough additional capacity to satisfy worldwide demand for flash memory. According to IDC (Worldwide
Flash Memory Card 2006-2010 Forecast, May 2006), the demand for flash memory cards is expected to rise
rapidly through 2010. Because flash memory is a key component of most of the products manufactured by our
customers, if any shortage in the supply of flash memory occurs and is not remedied, our customers may not be
able to purchase enough flash memory to manufacture their products and may therefore purchase fewer
semiconductor solutions from us than they would have otherwise purchased. Our ability to increase revenues and
grow our profits could be materially and adversely affected as a result of any shortage or decrease in the supply
of flash memory.

A failure to accurately forecast customer demand may result in excess or insufficient inventory, which

may increase our operating costs and harm our business.

To ensure the availability of our products for our customers, in some cases we cause our manufacturers to

begin manufacturing our products based on forecasts provided by these customers in advance of receiving
purchase orders. However, these forecasts do not represent binding purchase commitments, and we do not
recognize revenue from these products until they are shipped to the customer. As a result, we incur inventory and
manufacturing costs in advance of anticipated revenue. Because demand for our products may not materialize,
manufacturing based on forecasts subjects us to risks of high inventory carrying costs and increased obsolescence
and may increase our costs. If we overestimate customer demand for our products or if purchase orders are
cancelled or shipments delayed, we may end up with excess inventory that we cannot sell, which could have a
material and adverse effect on our financial results. Conversely, if we underestimate demand, we may not have
sufficient product inventory and may lose market share and damage customer relationships, which could also
harm our business.

The average selling prices of our products could decrease rapidly.

We may experience period-to-period fluctuations in future operating results if our average selling prices

decline. We may be forced to reduce the average unit price of our products in response to new product
introductions by us or our competitors, competitive pricing pressures and other factors. The semiconductor
market is extremely cost sensitive, which may result in declining average selling prices of the components
comprising our products. We expect that these factors will create downward pressure on our average selling
prices and operating results. To maintain acceptable operating results, we will need to develop and introduce new
products and product enhancements on a timely basis and continue to reduce our costs. If we are unable to offset
any reductions in our average selling prices by increasing our sales volumes or reducing corresponding
production costs, or if we fail to develop and introduce new products and enhancements on a timely basis, our
sales and operating results will be materially and adversely affected.

8

We rely primarily on a small number of distributors to market and distribute certain of our products, and

if we fail to maintain or expand these sales channels, our revenues would likely decline.

Most of our embedded graphics processors and some of our other products are sold through independent
distributors. Sales of these products to distributors generate a material amount of our revenues. Our business will
depend on our ability to maintain and expand our relationships with distributors, develop additional channels for
the distribution and sale of our products and effectively manage these relationships. Because not all of our
distributors are required to make a specified minimum level of purchases from us, we cannot be certain that they
will sell our products on a priority basis. As we continue to expand our indirect sales capabilities, we will need to
manage the potential conflicts that may arise within our indirect sales force. We also rely on our distributors to
accurately and timely report to us their sales of our products and to provide certain engineering support services
to customers. Our inability to obtain accurate and timely reports and to successfully manage these relationships
would have a material and adverse effect on our financial results.

The loss of any of our key personnel or the failure to attract or retain specialized technical and

management personnel could impair our ability to grow our business.

We rely heavily on the services of our key employees, including Wallace C. Kou, our President and Chief

Executive Officer. In addition, our engineers and other key technical personnel are a significant asset and are the
source of our technological and product innovations. We believe our future success will depend upon our ability
to retain these key employees and our ability to attract and retain other skilled managerial, engineering, technical
and sales and marketing personnel. The competition for such personnel, particularly technical personnel, is
intense in our industry. We may not be successful in attracting and retaining sufficient numbers of technical
personnel to support our anticipated growth. These technical personnel are required to refine the existing
hardware system and application programming interface and to introduce enhancements in future applications.
Despite the incentives we provide, our current employees may not continue to work for us, and if additional
personnel were required for our operations, we may not be able to obtain the services of additional personnel
necessary for our growth. In addition, we do not maintain “key person” life insurance for any of our senior
management or other key employees. The loss of any of our key employees or our inability to attract or retain
qualified personnel, including engineers, could delay the development and introduction of, and have an adverse
effect on our ability to sell, our products as well as our overall growth.

In addition, if any other members of our senior management or any of our other key personnel joins a

competitor or forms a competing company, we may not be able to replace them easily and we may lose
customers, business partners, key professionals and staff members. Substantially all of our senior executives and
key personnel have entered into confidentiality and non-disclosure agreements. In the event of a dispute between
any of our senior executives or key personnel and SMI Taiwan, we cannot assure you the extent, if any, to which
these provisions may be enforceable in Taiwan due to uncertainties involving the Taiwan legal system.

We may be unsuccessful in developing and selling new products or in penetrating new markets required

to maintain or expand our business.

Our revenue growth has been primarily from sales of our semiconductor solutions. Although we believe that

our acquisition of FCI will enable us to offer more comprehensive solutions for mobile devices, our future
success depends, in part, on our ability to develop successful new semiconductor solutions in a cost-effective and
timely manner. We continually evaluate expenditures for planned product developments and choose among
alternatives based upon our expectations of future market trends. The development of our semiconductor
solutions is highly complex, and successful product development and market acceptance of our products depends
on a number of factors, including:

•

•

our accurate prediction of the changing requirements of our customers;

our timely completion and introduction of new designs;

9

•

•

•

•

•

•

•

•

the availability of third-party manufacturing, assembly and test capacity;

the ability of our foundries to achieve high manufacturing yields for our products;

our ability to transition to smaller manufacturing process geometries;

the quality, price, performance, power efficiency and size of our products and those of our competitors;

our management of our indirect sales channels;

our customer service capabilities and responsiveness;

the success of our relationships with existing and potential customers; and

changes in industry standards.

We cannot assure you that we will be able to develop and introduce new or improved products in a timely
and cost-effective manner, that the products we introduce will generate significant revenues or that we will be
able to accurately anticipate or respond to future market trends.

We may not be able to deliver our products on a timely basis if our relationships with our suppliers, our

semiconductor foundries or our assembly and test subcontractors are disrupted or terminated.

We do not own or operate a semiconductor fabrication facility. Instead, we rely on third parties to

manufacture our semiconductors. Three outside foundries, UMC, in Taiwan, SMIC, in China, and
STMicroelectronics in Europe currently manufacture the majority of our semiconductors. As a result, we face
several significant risks, including higher wafer prices, lack of manufacturing capacity, quality assurance,
manufacturing yields and production costs, limited control over delivery schedules and product quality, increased
exposure to potential misappropriation of our intellectual property, labor shortages or strikes and actions taken by
third party contractors that breach our agreements.

The ability of each foundry to provide us with semiconductors is limited by its available capacity. We do
not have long-term agreements with any of these foundries and we place orders on a purchase order basis. We
place our orders based on our customers’ purchase orders and sales forecasts. However, the foundries can
allocate capacity to the production of the products of their other customers and reduce deliveries to our
manufacturing logistics partners on short notice or increase the price they charge us. It is possible that other
foundry customers that are larger and better financed than we are, or have long-term agreements with these
foundries, may induce these foundries to reallocate capacity to them. Any reallocation could impair our ability to
secure the supply of semiconductors that we need for our products. In addition, interruptions to the wafer
manufacturing processes caused by a natural disaster or human error could result in partial or complete disruption
in supply until we are able to shift manufacturing to another fabrication facility. It may not be possible to obtain
sufficient capacity or comparable production costs at another foundry. Migrating our design methodology to a
new third-party foundry could involve increased costs, resources and development time comparable to a new
product development effort. Any reduction in the supply of semiconductors for our products could significantly
delay our ability to ship our products and potentially have negative effects on our relationships with existing
customers and our results of operations. In addition, if our subcontractors terminate their relationships with us,
we would be required to qualify new subcontractors, which could take as long as six months, resulting in
unforeseen operations problems, and our operating results may be materially and adversely affected.

If the foundries that provide us with the products for our operations do not achieve satisfactory yield or

quality, or if the assembly and testing services fail us in the quality of their output, then our revenue,
operating results and customer relationships will be affected.

The manufacture of semiconductors is a highly complex process. Minor deviations in the manufacturing
process can cause substantial decreases in yield. In some situations, such deviations may cause production to be
suspended. The foundries that manufacture our semiconductors have from time to time experienced lower than

10

anticipated manufacturing yields, including yields for our semiconductors, typically during the production of new
products or architectures or during the installation and start-up and ramp-up of new process technologies or
equipment. If the foundries that manufacture our semiconductors do not achieve planned yields, our product
costs could increase, and product availability would decrease.

After the wafer fabrication processes, our wafers are shipped to our assembly and testing subcontractors. We

have a system to maximize consistent product quality, reliability and yield which involve our quality assurance
team working closely with pertinent subcontractors in the various phases of the assembly and testing processes.
We also emphasize a strong supplier quality management practice through which our quality assurance team
pre-qualifies our manufacturing suppliers and subcontractors. However, despite our efforts to strengthen supplier
quality management, if our foundries fail to deliver fabricated silicon wafers of satisfactory quality in the volume
and at the price we require, or if our assembly and testing subcontractors fail to efficiently and accurately
assemble and test our products, we will be unable to meet our customers’ demand for our products or to sell
those products at an acceptable profit margin, which would have a material and adverse effect on our sales and
margins and damage our customer relationships.

Failure to protect our proprietary technologies or maintain the right to certain technologies may

negatively affect our ability to compete.

We believe that the protection of our intellectual property rights will continue to be important to the success

of our business. We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions
on disclosure to protect our intellectual property rights. We also enter into confidentiality or license agreements
with our employees, business partners and other third parties, and have implemented procedures to control access
to and distribution of our documentation and other proprietary information. Despite these efforts, we cannot
assure you that these measures will provide meaningful protection of our intellectual property rights. Further,
these agreements do not prevent others from independently developing technologies that are equivalent to or
superior to our technology. In addition, unauthorized parties may attempt to copy or otherwise obtain and use our
proprietary technology. Monitoring unauthorized use of our technology is difficult, and we cannot be certain that
the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries, such as
China, where the laws may not protect our proprietary rights as fully as do the laws of the United States. In
addition, if the foundries that manufacture our semiconductors lose control of our intellectual property, it would
be more difficult for us to take remedial measures because our foundries are located in countries that do not have
the same protection for intellectual property that is provided in the United States. Also, some of our contracts,
including license agreements, are subject to termination upon certain types of change-of-control transactions.

We currently have more than 60 patents. We also have 78 patent applications pending in five countries. We
cannot be certain that patents will be issued as a result of our pending applications nor can we be certain that any
issued patents would protect or benefit us or give us adequate protection from competing products. For example,
issued patents may be circumvented or challenged and declared invalid or unenforceable or provide only limited
protection for our technologies. We also cannot be certain that others will not design around our patented
technology, independently develop our unpatented proprietary technology or develop effective competing
technologies on their own.

Failure to successfully defend against intellectual property lawsuits brought against us may adversely

affect our business.

As technology is an integral part of our design and product, we have, in the past, received communications
alleging that our products infringe or misappropriate certain intellectual property rights held by others, and may
continue to receive such communications in the future. We recently agreed with O2Micro International Limited
to settle several intellectual property disputes and both parties have started to withdraw their claims and
applications. See “Our Business — Legal Proceedings.” If any third party were to make valid intellectual
property infringement or misappropriation claims against us, we may be required to:

•

discontinue using disputed manufacturing process technologies;

11

•

•

•

•

stop selling products that contain allegedly infringing technology;

pay substantial monetary damages;

seek to develop non-infringing technologies, which may not be feasible; or

seek to acquire licenses to the infringed technology, which may not be available on commercially
reasonable terms, if at all.

If our products are found to infringe or misappropriate third-party intellectual property rights, we may be
subject to significant liabilities and be required to change our manufacturing processes or products. This could
restrict us from making, using, selling or exporting some of our products, which could in turn materially and
adversely affect our business and financial condition. Our failure to develop non-infringing technologies or
license intellectual property rights in a timely and cost-effective manner could materially and adversely affect our
business and financial condition. In addition, any litigation, whether to enforce our patents or other intellectual
property rights or to defend ourselves against claims that we have infringed the intellectual property rights of
others, could, regardless of the ultimate outcome, materially and adversely affect our operating results by
requiring us to incur significant legal expenses and diverting the resources of the company and the attention of
management.

Failure to achieve and maintain technological leadership in our various multimedia consumer

electronics markets could erode our competitiveness and cause our profits to decrease.

The consumer electronics market and the semiconductor components used in such market are constantly
changing with increased demand for improved features such as low power or smaller size. If we do not anticipate
these changes in technologies and rapidly develop and introduce new and innovative technologies, we may not be
able to provide advanced semiconductor solutions on competitive terms. If we are unable to maintain the ability
to provide advanced semiconductor solutions on competitive terms, some of our customers may buy
semiconductor solutions from our competitors instead of us. To be competitive, we must anticipate the needs of
the market and successfully develop and introduce innovative new products in a timely fashion. We cannot
assure you that we will be able to successfully complete the design of our new products, have these products
manufactured at acceptable manufacturing yields, or obtain significant purchase orders for these products.
Furthermore, if our future innovations are ahead of the then-current technological standards in our industry,
customers may be unwilling to purchase our platforms until the multimedia consumer electronics market is ready
to accept them. The introduction of new products may adversely affect sales of existing products and contribute
to fluctuations in our operating results from quarter to quarter. Our introduction of new products also requires
that we carefully manage our inventory to avoid inventory surplus and obsolescence. Our failure to do so could
have a material and adverse effect on our operating results. Furthermore, failure to achieve advances in
technology or processes or to obtain access to advanced technologies or processes developed by others could
erode our competitive position.

Development of new platforms and products may require us to obtain rights to use intellectual property that

we currently do not have. If we are unable to obtain or license the necessary intellectual property on reasonable
terms or at all, our product development may be delayed, the gross margins on our planned products may be
lower than anticipated and our business and operating results would be materially and adversely affected.

Because the markets in which we compete are highly competitive and many of our competitors have
greater resources than we have, we cannot be certain that our products will compete favorably in the market
place.

We face competition from a large number of competitors in each of our targeted areas. We currently
compete with other companies that produce flash storage controllers, such as Alcor Micro, Chipsbank, Genesys,
Incomm, Phison, Samsung, Skymedi, and USBest. We may also face competition from some of our customers
who may develop products or technologies internally that compete with our solution. For multimedia SoC

12

products, the companies with whom we compete include Actions, ALi, AMD, NVIDIA, Rockchip, SigmaTel,
and Vimicro. For mobile communications products, the companies with whom we compete include Analog
Devices, Infineon, Qualcomm, NXP, RFMD and Skyworks. We expect to face increased competition in the
future from our current and potential competitors. In addition, some of our customers have developed products
and technologies that could replace their need for our products or otherwise reduce their demand for our
products.

Many of our current and potential competitors have longer operating histories, greater name recognition,

access to larger customer bases and significantly greater financial, sales and marketing, manufacturing,
distribution, technical and other resources than we have. As a result, they may be able to respond more quickly to
changing customer demands or to devote greater resources to the development, promotion and sales of their
products than we can. Our current and potential competitors may develop and introduce new products that will be
priced lower, provide superior performance or achieve greater market acceptance than our products. In addition,
in the event of a manufacturing capacity shortage, these competitors may be able to obtain capacity when we are
unable to do so.

The multimedia consumer electronics market, which is a principal end market for our products, has
historically been subject to intense price competition. In many cases, low-cost, high-volume producers have
entered the markets and driven down profit margins. If a low-cost, high-volume producer should develop
products that compete with our products, our sales and profit margins would suffer.

Fluctuations in exchange rates could result in foreign exchange losses.

Our reporting currency is the NT dollar. However, a significant portion of our operating expenses is
denominated in currencies other than the NT dollar, primarily U.S. dollars, but also, to a lesser extent, Japanese
Yen, Renminbi, Euros, and South Korean Won. As a result, appreciation or depreciation of other currencies in
relation to the NT dollar could result in material transaction or translation gains or losses that could adversely
affect, or cause fluctuations in, our results of operations. We do not currently engage in currency hedging
activities.

Our products must meet exacting specifications and undetected defects and failures may occur, which
may cause customers to return or stop buying our products and may expose us to product liability risk and
risks of indemnification against defects in our products.

Our products are complex and may contain undetected hardware or software defects or failures, especially

when first introduced or when new versions are released. These errors could cause us to incur significant
re-engineering costs, divert the attention of our engineering personnel from product development efforts and
materially affect our customer relations and business reputation. If we deliver products with errors or defects, our
credibility and the market acceptance and sales of our products could be harmed. Defects could also lead to
liability for defective products as a result of lawsuits against us or against our customers. We have agreed to
indemnify some of our customers in some circumstances against liability from defects in our products. A
successful product liability claim could require us to make significant damage payments.

Our intellectual property indemnification practices may adversely impact our business.

We may be required to indemnify our customers and our third-party intellectual property providers for
certain costs and damages of intellectual property infringement in circumstances where our products are a factor
in creating the customer’s or these third-party providers’ infringement exposure. This practice may subject us to
significant indemnification claims by our customers and our third-party providers. In some instances, our
products are designed for use in devices manufactured by our customers that comply with international standards,
such as the MP3 compression standard. These international standards are often covered by patent rights held by
third parties, which may include our competitors. The combined costs of identifying and obtaining licenses from

13

all holders of patent rights essential to such international standards could be high and could reduce our
profitability or increase our losses. The cost of not obtaining these licenses could also be high if a holder of the
patent rights brings a claim for patent infringement. In the contracts under which we distribute semiconductor
products, we generally have agreed to indemnify our customers against losses arising out of claims of
unauthorized use of intellectual property. In some of our licensing agreements, we have agreed to indemnify the
licensor against losses arising out of or related to our conduct or services. We cannot assure you that additional
claims for indemnification will not be made or that these claims would not have a material and adverse effect on
our business, operating results or financial condition.

Major earthquakes, fires or other natural disasters and resulting systems outages may cause us

significant losses.

Our principal executive offices and a significant part of our operations are based in Taiwan. Many of our

suppliers, providers of semiconductor manufacturing services for us, including semiconductor foundries and
primary subcontractors for the assembly and testing of our products are located in Taiwan.

Taiwan is particularly susceptible to earthquakes. For example, in September 1999, Taiwan experienced a

severe earthquake that caused significant property damage and loss of life, particularly in the central part of
Taiwan. Although earthquakes and other natural disasters in Taiwan have not caused serious damages to us, if
we, our suppliers, providers of semiconductor manufacturing services and primary subcontractors are affected by
an earthquake or other natural disasters, such as typhoons, our production schedule could be interrupted or
delayed. As a result, a major earthquake, natural disaster or other disruptive events in Taiwan could severely
disrupt the normal operation of business and have a material and adverse effect on our financial condition and
operating results.

The manufacturers of our semiconductors use highly flammable materials such as alcohol, acetone, photo

resistance, AsH3 and pH3, in the manufacturing processes and are therefore subject to the risk of loss arising
from explosion and fire. The risk of explosion and fire associated with these materials cannot be completely
eliminated. Semiconductor companies experience explosion and fire damage from time to time. If any of their
fabs or assembly facilities were to be damaged or cease operations as a result of an explosion or fire, it could
reduce their manufacturing capacity. Such a reduction in the manufacturing capacity of our manufacturers could
disrupt the production schedule of our products thereby causing us to miss orders from our customers, which will
in turn have a material and adverse effect on our business and operating results.

The recurrence of a severe acute respiratory syndrome outbreak or an outbreak of avian influenza or

other outbreaks could materially and adversely affect our operating results and financial conditions.

In early 2003, China and certain other areas in Asia experienced an outbreak of severe acute respiratory
syndrome, or SARS. In addition, in the spring of 2004, China had several reported cases of deaths caused by
SARS. A general downturn in most Asian economies accompanied the outbreak.

In 2003, an outbreak of avian influenza affected bird and poultry populations in countries throughout

Southeast Asia and other parts of Asia, including China, Hong Kong and Japan. Avian influenza resulted in
human deaths in Vietnam and Thailand. Any recurrence of SARS, avian influenza or other outbreak may have a
negative effect on our operations. Our operations may be impacted by a number of health-related factors,
including, among other things, quarantines or closure of our offices, the sickness or death of our key officers and
employees and a general slowdown in the economies of China, Hong Kong and Taiwan, among other countries
where we have operations.

Our inability to achieve and maintain effective internal control over financial reporting could negatively

impact our business, our results of operations and the market price of our ADSs.

SEC rules implementing Section 404 of the Sarbanes-Oxley Act of 2002 require us to include in our Annual

Reports on Form 20-F a report by our management on our internal control over financial reporting that contains

14

our management’s assessment of the effectiveness of our internal control over financial reporting. In addition,
beginning next year, our independent auditor must attest to and report on management’s assessment. We expect
to incur additional costs and use significant management and other resources in an effort to comply with
Section 404 of the Sarbanes-Oxley Act and other requirements associated with our public company reporting
requirements that we did not incur as a private company.

Our management could potentially conclude that our internal controls over financial reporting are not
effective. Even if our management concludes that our internal controls are effective, our independent auditor may
disagree with management’s assessment. Alternatively, our independent auditor may decline to attest to our
management’s assessment or may issue an adverse opinion if its interpretation of the requirements differs from
our or it is otherwise dissatisfied with our internal control over financial reporting or the level at which our
internal control over financial reporting is documented, designed, operated or reviewed. Any of these possible
scenarios could cause investors to lose confidence in the reliability of our consolidated financial statements,
which could result in a decline in the market price of our ADSs. Moreover, if we fail to maintain acceptable
internal control over financial reporting, fail to implement required new or improved controls, or experience
difficulties in their implementation, our business and operating results could suffer, we could fail to meet our
reporting obligations, and the market price of ADSs could decline as a result.

Our stock price has been, and may continue to be, volatile, which could result in investors losing all or

part of their investments.

The market price of our ADSs has fluctuated significantly in the past and may continue to fluctuate in the

future. We believe that such fluctuations will continue as a result of many factors, including future
announcements concerning us, our competitors or the semiconductor industry in general or principal customers
regarding financial results or expectations, technological innovations, industry supply dynamics, new product
introductions, governmental regulations, the commencement or results of litigation or changes in earnings
estimates by analysts. In addition, in recent years the stock market has experienced significant price and volume
fluctuations and the market prices of the securities of high technology and semiconductor companies have been
especially volatile, often for reasons outside the control of the particular companies. These fluctuations as well as
general economic, political and market conditions may have an adverse affect on the market price of our ADSs.

We may make acquisitions that are dilutive to existing stockholders, result in unanticipated accounting
charges or otherwise adversely affect our results of operations, and result in difficulties in assimilating and
integrating the operations, personnel, technologies, products and information systems of acquired companies
or businesses.

We continually evaluate and explore strategic opportunities as they arise, including business combinations

and capital investments. If we issue equity securities in connection with an acquisition, the issuance may be
dilutive to our existing stockholders. Alternatively, acquisitions made entirely or partially for cash would reduce
our cash reserves.

Acquisitions may require significant capital infusions, typically entail many risks and could result in

difficulties in assimilating and integrating the operations, personnel, technologies, products and information
systems of acquired companies. In order to realize the intended benefits of acquisitions, we will have to
successfully integrate and retain key personnel. We may experience delays in the timing and successful
integration of acquired technologies and product development through volume production, unanticipated costs
and expenditures, changing relationships with customers, suppliers and strategic partners, or contractual,
intellectual property or employment issues. In addition, key personnel of an acquired company may decide not to
work for us. The acquisition of another company or its products and technologies may also result in our entering
into a geographic or business market in which we have little or no prior experience. These challenges could
disrupt our ongoing business, distract our management and employees, harm our reputation, subject us to an
increased risk of intellectual property and other litigation and increase our expenses. These challenges are

15

magnified as the size of the acquisition increases, and we cannot assure you that we will realize the intended
benefits of any acquisition. Acquisitions may require large one-time charges and can result in increased debt or
contingent liabilities, adverse tax consequences, substantial depreciation or deferred compensation charges, the
amortization of identifiable purchased intangible assets or impairment of goodwill, any of which could have a
material adverse effect on our business, financial condition or results of operations.

Mergers and acquisitions of high-technology companies are inherently risky and subject to many factors

outside of our control, and no assurance can be given that our previous or future acquisitions will be successful
and will not materially adversely affect our business, operating results, or financial condition. Failure to manage
and successfully integrate acquisitions could materially harm our business and operating results. Even when an
acquired company has already developed and marketed products, there can be no assurance that such products
will be successful after the closing, will not cannibalize sales of our existing products, that product enhancements
will be made in a timely fashion or that pre-acquisition due diligence will have identified all possible issues that
might arise with respect to such company.

Political, Regulatory and Economic Risks

We face substantial political risks associated with doing business in Taiwan because of the tense political

relationship between Taiwan and the People’s Republic of China.

While we also, through our acquisition of FCI, maintain substantive operations in Korea. our principal
executive offices and a majority of our employees and a significant amount of our research and development and
operations are based in Taiwan. In addition, two of our primary third party manufacturers, UMC and SMIC, are
located in Taiwan and China, respectively. Accordingly, our business and results of operations and the market
price of our ADSs may be affected by changes in Taiwan governmental policies, taxation, inflation or interest
rates and by social instability and diplomatic and social developments in or affecting Taiwan that are outside of
our control. Taiwan has a unique international political status. China does not recognize the sovereignty of
Taiwan. Although there have been significant economic and cultural ties between the Taiwan and China in recent
years, the political relations have often been strained. The government of China has indicated that it may use
military force to gain control over Taiwan, particularly under what it considers as highly provocative
circumstances, such as a declaration of independence by Taiwan or the refusal by Taiwan to accept China’s
stated “one China” policy. On March 14, 2005, the National Peoples’ Congress of China passed what is widely
referred to as the “anti-secession” law, a law authorizing the Chinese military to attack in order to block moves
by Taiwan toward formal independence. Past developments in relations between Taiwan and China have on
occasion depressed the market prices of the securities of Taiwanese companies. Relations between Taiwan and
China and other factors affecting military, political or economic conditions in Taiwan could have a material
adverse effect on our financial condition and results of operations, as well as the market price of our ADSs.

The relations between Taiwan and China and other factors affecting military, political or economic
conditions in Taiwan could also have a material and adverse effect on the financial condition of two of our
primary foundries that manufacture most of our semiconductors. One of the foundries, UMC, is located in
Taiwan, and the other, SMIC, is located in China. Such relations between Taiwan and China and other factors
could also have a material and adverse effect on the financial condition of SPIL and King Yuan Electronics, two
of our primary subcontractors for the assembly and testing of our products, which are also located in Taiwan. In
addition, any expansion or development of our research and development team in China could be restricted or
jeopardized, and our sales and marketing performance may be affected.

Our business depends on the support of the Taiwan government, and a decrease in this support may

increase our tax liabilities and decrease our net income.

The Taiwan government has been very supportive of technology companies such as ours. In particular, we,

like many Taiwanese technology companies, have benefited from tax incentives provided by the Taiwan

16

government. For example, under the Statute for Upgrading Industries of Taiwan, we are granted tax credits by
the Taiwan Ministry of Finance at rates set at certain percentages of the amounts utilized in qualifying research
and development costs and in qualifying employee training expenses. If such tax credits cannot be utilized in the
fiscal year in which the relevant costs or expenses were incurred, they may be carried forward for up to the next
four years. In addition, Taiwan law offers preferential tax treatments to industries that are encouraged by the
Taiwan government. These preferential tax treatments include 5-year tax exemptions for income attributable to
expanded production capacity or newly developed technologies funded in whole or in part by proceeds from
initial capital investments made by our shareholders, or subsequent capital increases, or capitalization of our
retained earnings. Such tax exemptions may be available either to the shareholders of a company, or, if the
shareholders so determine, to the company itself. SMI Taiwan has filed three applications for such tax
exemptions as SMI Taiwan had used the proceeds of the new share offerings received in 2002, 2003 and 2004 to
fund eligible research and development projects. In the first quarter of 2005, SMI Taiwan received certain
requisite consents or approvals for tax exemptions. See “Management’s Discussion and Analysis of Financial
Conditions and Results of Operations — Principal Factors Affecting Our Results of Operations — Provision for
income taxes” and note 13 to our consolidated financial statements for a more detailed description of our ability
to enjoy these preferential tax treatments. If any of our tax credits or our ability to take advantage of these
preferential tax treatments are curtailed or eliminated, our net income may decrease materially.

If we are unable to satisfy the conditions set by the Investment Commission of the Taiwan Ministry of

Economic Affairs, or the IC, the effectiveness of the share exchange leading to the establishment of our
current corporate structure could be challenged by the ROC government authorities.

Our current corporate structure is established as a result of a share exchange between us and the

shareholders of SMI Taiwan. Approval from the IC was sought and successfully granted for the share exchange.
However the IC granted the approval on condition that SMI Taiwan must firstly, apply for at least five patents in
each of 2005, 2006 and 2007, secondly, employ between 15 to 20 research and development engineers in each of
2005, 2006, and 2007, and finally, maintain research and development expenditures in the amount of at least
NT$100 million (US$3.0 million) in each of 2005, 2006, and 2007. We are required to submit to the IC SMI
Taiwan’s annual financial statements audited by a certified public accountant and other relevant supporting
documents in connection with the implementation of those three conditions within four months after the end of
each of 2005, 2006 and 2007. To the extent that we are unable to satisfy any of those three conditions, the IC
may revoke our rights of repatriation of profits to be distributed by SMI Taiwan or rescind its approval of the
share exchange. This would have an adverse effect on our corporate structure and consequently, materially and
adversely affect our ability to conduct our business.

Overview

We are a fabless semiconductor company that designs, develops and markets universally compatible, high-

performance, low-power semiconductor solutions for the multimedia consumer electronics market. We have
three major product lines: our mobile storage business, multimedia SoC business, and mobile communications
business. Our mobile storage business is our significantly larger business and is composed of microcontrollers,
also commonly known as controllers, used in NAND flash memory storage products such as flash memory cards,
USB flash drives and card readers. These flash memory storage products are widely used by consumers to store
data on multimedia consumer electronics devices such as mobile phones, digital still cameras, personal digital
assistants, personal navigation devices and personal multimedia players, and notebook and desktop personal
computers. Our multimedia SoC business is composed of products that support MP3 and personal multimedia
players, PC cameras and embedded graphics applications. Our mobile communications business is composed of
mobile TV tuners, CDMA RF ICs and electronics toll collection RF ICs, which became our new product line as a
result of our recent acquisition of FCI.

We sell our semiconductor solutions to leading original equipment manufacturers (“OEMs”) and original

design manufacturers (“ODMs”) worldwide. We provide our high performance flash memory storage controller
to companies such as Lexar Media, Samsung, Sony, STMicroelectronics, and Transcend. We are a leading
supplier of controllers used in flash memory cards sold bundled with mobile phones manufactured by the handset

18

industry’s leading OEMs. Our multimedia SoCs are important components of MP3 and embedded graphics
applications that are sold by companies such as Advantech, Fuji Xerox, GE, Intel, Kontron, Mattel, Panasonic,
Philips, Sharp, Siemens, Sony, Thomson and Toshiba. We provide our innovative mobile communications ICs to
LG Electronics, Pantech & Curitel, Samsung and other companies. We sell our products through our direct sales
force and distributors in Canada, China, Europe, Japan, Korea, Singapore, Taiwan and the United States.

We have experienced rapid growth in our net sales. Our net sales grew from approximately NT$915.1
million in 2003 to approximately NT$2,166.7 million in 2004 to approximately NT$2,686.5 million in 2005 to
approximately NT$3,460.5 million (US$106 million) in 2006, representing a compound annual growth rate, or
CAGR of approximately 56%.

Recent Acquisition of Future Communications IC, Inc.

In April 2007, we acquired Future Communications IC, Inc. FCI is a leading designer of RF ICs for mobile
TV and wireless communications based in Seoul, South Korea. The final purchase price for the transaction was
approximately US$50 million in cash and US$40 million in our ordinary shares and options to purchase our
ordinary shares. We have agreed to pay FCI shareholders up to an additional $12 million in cash under certain
circumstances. The first condition is that FCI achieves, for its fiscal year 2007 ending December 31, 2007, a $33
million revenue target and a 53% product margin target. The second condition relates to the performance of our
stock. If both the FCI revenue and product margin targets are reached, we have agreed to pay to FCI shareholders
in cash the difference between US$12 million and 90% of the appreciation of our ADSs over an agreed period of
time in the stock portion of the consideration received as part of this transaction. Before the inclusion of FCI
acquisition-related charges, management expects that the transaction will be slightly accretive to earnings in
2007 and meaningfully accretive in 2008 and beyond.

Industry Background

The convergence of consumer electronics, communications, and computing devices has been accelerating at a
faster rate in recent years as advances in technology enable different categories of electronic devices to offer similar
functionalities, which often involve the processing, storage, and transfer of digital multimedia content. Mobile
phones for example have been transformed into multimedia consumer electronics devices with camera, video
recorder, music player, e-mail, internet access, television, and other functions, because mobile phones have
increasingly sophisticated multimedia applications processing, data storage, and data transfer capabilities. Personal
computers have also been transformed into multimedia consumer electronics devices by multimedia data
processing, storage, and transfer technologies that include wireless connectivity, internet telephony, video
telephony, and more advanced video and audio capabilities. Several important semiconductor technology
developments have led to the significant improvement by electronics devices to process, store, and transfer digital
multimedia content and these include the development of NAND flash as a widely used data storage medium,
various high-performance multimedia application processors and advanced communication-related RF ICs.

Some of the key factors that are currently driving digital media semiconductor development include:

Proliferation of digital media content. Advances in digital technology have enabled audio, photo and video
content to be digitized, transmitted, stored and catalogued. As the accessibility of digital media content continues
to proliferate, demand has increased for a range of new digital consumer devices such as mobile phones with
multimedia features, MP3 and other personal multimedia players, PC cameras, notebook PCs, and car navigation
systems. Due to the proliferation of these devices, consumers will demand the ability to create, store, exchange
and play back more digital media content than ever before. Two of the leading types of mobile storage of digital
media content are flash memory cards and USB flash drives.

Greater storage capacity and advances in storage technologies. As technology advances, more and more

memory-intensive applications have been developed to cater to consumer demands. For example, the resolution
of consumer digital still cameras has increased from approximately one megapixel to eight megapixels or greater.

19

The average resolution of camera phones has also been increasing. Correspondingly, greater capacity is required
to store the increasingly larger size of digital photo collections, personal digital audio libraries and digital videos.
Rapid increase in NAND flash storage capacity and performance and rapid reduction in cost of NAND flash have
allowed memory card using NAND flash to become the predominant memory medium to store such increasing
digital media content.

Demand for greater mobility. Consumers are increasingly using portable devices to compute and exchange

data, enjoy music including radio, take pictures and video, watch television and communicate with each other.
Developments in high-speed wireless transmission protocols, such as CDMA, WCDMA, DAB, DVB-H,
T-DMB, and S-DMB facilitate the one-way or two-way sharing and exchange of content and depend on high
sensitivity, low power, high performance, small size, and low cost RF ICs for the sending and receiving of data.

Demand for smaller, lighter and more power-efficient electronic devices. Consumers are increasingly
demanding portable electronic devices that enable them to enjoy digital media, communicate, and compute
independent of physical location. To respond to demand for smaller, lighter and more power-efficient portable
electronic devices, manufacturers are increasingly seeking highly-integrated multimedia solutions, such as
system on chip (“SoC”) for MP3 players, embedded graphics applications and PC cameras.

Our Markets and Products

We design, develop and supply a portfolio of products targeted to multimedia consumer electronics
applications. Our current product offerings are primarily targeted at three main markets: mobile storage,
multimedia SoCs and mobile communications markets. The following is a brief description of each of our target
markets.

Mobile Storage Products

We offer a broad range of controllers for NAND flash memory storage products, including flash memory
cards, USB flash drives and card readers, and have recently began offering embedded controller solutions and
controllers for solid state drives. Flash memory storage products are widely used by consumers to store data for
multimedia consumer electronics devices such as mobile phones, digital still cameras, personal digital assistants,
personal navigation devices, personal multimedia players, and notebook and desktop PCs. Flash memory cards
and USB flash drives are two of the largest end applications for NAND flash. Our controllers are designed to be
compatible with and the companion IC to the vast majority of NAND flash produced by companies such as
Hynix, Intel, Micron, Samsung, STMicroelectronics and Toshiba. Because NAND flash from different
manufacturers may be dissimilar in terms of IC packaging, input/output timing, command code and other factors,
a controller plays an important role in ensuring NAND flash used in flash memory storage products are
compatible with consumer electronics host devices. New NAND flash from different manufacturers or the same
vendor may require updates to the firmware in the controller, extensive and thorough debugging and testing of
the controller with the updated NAND flash driver and extensive and thorough compatibility testing of the
NAND flash memory storage product.

Key functions of our flash memory card and USB flash drive controllers include:

• managing data input and output between the NAND flash in the flash memory storage product and the

consumer electronics host device;

•

•

•

ensuring that flash memory storage products which use our controllers are compatible with the widest
possible universe of consumer electronics host devices;

ensuring data reliability in NAND flash by detecting and correcting single bit errors in the NAND flash;

on a larger scale, ensuring data integrity in a NAND flash by mapping bad blocks and preventing the
bad blocks from being used for storing data;

20

• maximizing the life of a NAND flash with wear-leveling algorithms which spreads out the use of the

memory array and equalizes the use of all the memory cells;

•

•

enhancing the read and write performance of NAND flash by utilizing two-plane architecture,
interleaving, or other technologies; and

implementing security features to protect software code, personal data and multimedia digital rights.

Flash memory card controllers. NAND flash memory cards are non-volatile, solid state storage media that

have become the predominate media for the storage of multimedia data used in mobile phones, digital still
cameras and other portable consumer electronic devices because of their small and compact form factor, large
storage capacity, low power consumption, high speed data transfer rate, and support of certain copyright
protection technologies.

We believe we offer the broadest line of high-performance controllers for all major NAND flash memory

card formats, including Compact Flash (“CF”), Memory Stick, MultiMedia Card (“MMC”), Secure Digital
(“SD”) and xD-Picture Card (“xD”), as well as sub-types of these formats, such as SD card’s miniSD card and
microSD card. We believe that our controllers are compatible with the majority of NAND flash currently being
produced by different flash memory manufacturers, including small and big block Single-Level Cell (“SLC”) and
Multi-Level Cell (“MLC”) NAND flash.

Our proprietary IC design methodology, strong firmware capability, proprietary assembly techniques and
comprehensive testing procedures enable us to offer controllers that have significant competitive advantages with
respect to compatibility, speed, connectivity and cost. Based on our proprietary QuickWrite technology, we
believe our controllers outperform competing products on product benchmarking tests. Our FastMDC technology
enables high performance flash memory access time and high reliability of data storage. Our flash memory
controllers are also designed for very low stand-by power consumption, to withstand electro-static discharge and
to allow flexible flash memory configuration through both hardware and firmware. Our flash memory controller
ICs are manufactured using standard CMOS processes at 0.18 micron and 0.16 micron.

USB flash drive controllers. USB flash drives are NAND flash memory data storage devices integrated with

a standard USB (“universal serial bus”) interface, commonly high speed USB 2.0. They are typically small,
lightweight, removable and rewritable. USB flash drives are more compact, generally faster, have large capacity
for data and are more robust and reliable than other types of portable storage devices such as hard disk drives and
CD or DVD optical storage medium used with optical drives.

Our high performance USB flash drive controllers can support single and dual-channel SLC and MLC
NAND flash configuration and are compatible with the majority of flash memory currently being produced by
different flash memory manufacturers. They are designed for high data transfer rates, low power consumption,
offer our customers an overall low cost solution with integrated voltage regulators and stand-by power
components and support Master and Slave SPI (“Serial Peripheral Interface”) for applications such as a
fingerprint sensor. Our controllers can support Microsoft Vista’s ReadyBoost, which increases a PC’s respond
time by caching application data on a USB flash drive that supplements a PC’s RAM. Our ICs are manufactured
using CMOS processes at 0.16 micron.

Card reader controllers. Because flash memory cards are widely used with a wide range of consumer,
computing, and communications devices, including mobile phones, digital still cameras, desktop and notebook
PCs, printers, and TVs, these devices require either external or internal card readers.

We believe that we are uniquely placed to supply controllers for card readers that can support the widest
range of flash memory cards because we supply more flash memory card controllers and for a wider range of
card formats using a wider range of NAND flash from different manufacturers than any of our competitors. Our
card reader controllers are designed to support single or multiple card slots for all the popular card formats, such
as CF, Memory Stick, MMC, SD and xD. Our card reader controllers can also assist host device OEMs in
implementing certain security features.

21

Other storage controllers. In addition to controllers for flash memory cards, USB flash drives and card

readers, we have recently developed and have shipped to customers embedded controller solutions and
controllers for solid state drives. Our embedded controller solutions include controllers mounted on the printed
circuit board of electronic devices, such as DVD players and flat panel TVs, used to control NAND flash also
mounted on the printed circuit board of the device, as well as controllers contained in a single semiconductor
package with one or more companion NAND flash dies. Our controllers for solid state drives have been
developed for use in certain notebook PCs and camcorders and digital 35mm single lens reflex cameras that have
replaced tape storage or hard disk drives with solid state drivers.

Multimedia SoCs

We design and develop a wide range of multimedia SoCs for MP3 and personal multimedia players,
embedded graphics applications and PC cameras. SoCs are integrated circuits that include a central processing
unit, memory interfaces and other components and that address a range of end application requirements,
including low power, high performance, low cost and high levels of system integration. Our SoCs are
manufactured using standard CMOS processes.

Personal media player SoCs. Personal media players are battery-powered, flash memory-based portable

devices that store and play digital media such as audio, photos and video. The market for personal compressed
audio players, commonly referred to as MP3 players, has grown rapidly and is beginning to incorporate other
functions, such as video and wireless connectivity. MP3 players have become one of the most popular consumer
electronics devices and have largely replaced personal cassette players and other traditional audio players.

We focus on SoCs for personal media players that use NAND flash as the data storage medium, the
principal type of medium for these devices, which have largely replaced hard disk drive as a storage medium
except for the largest memory capacity devices. Our solutions are designed to enable personal media players to
manage thousands of digital media files, the number of which is limited to a large extent only by the capacity of
the NAND flash used in the device. Personal media player SoCs are integrated solutions based on two key
technology building blocks, codecs for audio and other media and a NAND flash controller, which is a Silicon
Motions core technology. The capabilities of a personal media player’s NAND flash controller is an important
factor because the cost of NAND flash is a very large percentage of a personal media player’s bill of materials
and the largest category of cost.

Our personal media player SoCs are high performance, low power single-chip solutions that feature MP3

and WMA audio and JPEG image decoders, a NAND flash controller, power management, supports Microsoft’s
Windows Media DRM and interfaces to an FM module, USB 2.0, flash memory card formats, such as SD and
MMC, and color LCD. Our newer generation SoCs also feature a motion JPEG digital signal processor.

Embedded graphics processors. Graphics processors are commonly used by desktop and notebook PCs,
game consoles, work stations and multimedia mobile phones to increase the speed and complexity of images that
can be displayed on a monitor, TV or screen, as well as improve color definition and image resolution. Graphics
processors are also used to control the displays of servers and a wide range of consumer and lifestyle, medical
and industrial, office equipment, entertainment and other products.

Before we combined our business with Feiya in 2005, SMI USA was principally a graphics processor
company. We are currently focused primarily on designing, developing and marketing high-performance,
low-power SoCs which contain a graphics processor engine and embedded memory and are highly integrated and
low cost, small chip size, easy to design-in by systems integrators, and fully supported and not end-of-life. The
markets in which we compete include low-end servers, consumer and lifestyle products, medical and industrial
applications, office equipment and non-game console entertainment devices. Our embedded graphics processors
are generally used to render text, 2D graphics and graphical user interface (GUI) on displays.

22

Based on our DualMon technology, our display controllers can drive two separate displays using one
controller. This saves on costs as well as board estate. Our ReduceOn® technology enables intelligent power
management which algorithmically varies the clock and power to functional units based on system needs to
significantly reduce average operating power usage. End-users can thus use the mobile devices for longer periods
without a reduction in performance.

Image processors. With improvements in the bandwidth of broadband internet access and video telephony
software, consumers are increasingly using desktop and notebook PCs equipped with webcams to conduct video
telephony and conferences. An image processor is required to process and enhance the image captured by the
CMOS image sensors located behind the lens of a webcam.

Our single chip image controller for USB 2.0 PC camera solutions supports CMOS image sensors of up to
2.0 megapixels. Our SoC integrates the color processor engine, JPEG compression, AC-Link/IIS audio interface
and high-speed USB 2.0 device controller and also supports all legacy PC systems equipped with USB 1.1 host
interfaces.

Mobile Communications

Beginning in May 2007, we started offering semiconductor solutions for mobile TV, mobile telephony, and

electronic toll collection systems. Our new mobile communications portfolio of products became a part of our
company following the completion of our acquisition of FCI at the end of April 2007. The core technology of
FCI is RF ICs for mobile communications, whether for receiving mobile TV signals on mobile phones, receiving
and transmitting voice, video and data on mobile phones or receiving and transmitting data between automobiles
and highway toll collection systems for the wireless collection of toll fees.

Mobile TV tuners. Our products include mobile TV tuners for mobile phones. Our tuners are designed for
many mobile TV broadcast standards including S-DMB and T-DMB. Our solutions for DVB-H, ISDB-T, and
StiMi are currently under development. Our tuners can also receive digital audio broadcast (DAB) signals.
According to competitor product benchmarking, we believe our mobile TV are among the best in the market in
terms of smallest chip size, lowest power consumption, lowest noise and high adjacent channel selectivity (ACS).
We cooperate closely with many demodulator IC partners and sell our products in die form or in a SiP in
combination with a demodulator die provided by our demodulator IC partner.

CDMA RF ICs. We offer CDMA transmitters, receivers, transceivers, low noise amplifiers (LNA) and

power amplifiers (PA).

Electronic toll collection system RF ICs. We are the sole supplier of transceiver ICs for Korea’s electronic

toll collection system.

Our Customers

We sell our semiconductor solutions to leading original equipment manufacturers, or OEMs, and original

design manufacturers, or ODMs, worldwide. We provide our high performance flash memory storage controller
to companies such as Lexar Media, Samsung, Sony, STMicroelectronics, and Transcend. We are a leading
supplier of controllers used in flash memory cards sold bundled with mobile phones manufactured by the handset
industry’s leading OEMs. Our multimedia SoCs are important components of MP3 and embedded graphics
applications that are sold by companies such as Advantech, Fuji Xerox, GE, Intel, Kontron, Mattel, Panasonic,
Philips, Sharp, Siemens, Sony, Thomson and Toshiba. We provide our innovative mobile communications ICs to
LG Electronics, Pantech & Curitel, Samsung and other companies.

Sales to our five largest customers represented approximately 35%, 40% and 57% of our net revenue in
2006, 2005 and 2004, respectively. We only had one customer in 2006 and 2005 that accounted for 10% or more

23

of our sales, and three customers in 2004 that accounted for 10% or more of our sales in 2004. The identities of
our largest customers and their respective contributions to our net revenue have varied and will likely continue to
vary from period to period.

Sales to our customers may be significantly higher if indirect sales are included with direct sales. In 2006,

Samsung Electronics was our sixth largest customer and accounted for approximately 4% our sales. In 2006,
ATP Electronics and Barun Electronics were our second and seventh largest customers and accounted for
approximately 9% and 4% of our sales, respectively. We believe a substantial portion of our sales to ATP
Electronics and Barun Electronics are included in the products of Samsung Electronics and that such direct and
indirect sales to Samsung Electronics amounted to between 13% and 15% of our net sales. We believe that if our
sales to ATP Electronics and Barun Electronics were included in our sales to Samsung Electronics in 2005 and
2004, such direct and indirect sales to Samsung Electronics would amount to between 10% and 12% and 4% and
5% in the respective years. In 2006, 2005 and 2004, Lexar Media was our ninth, fourth and second largest
customer and accounted for approximately 3%, 7% and 13% of our sales in the respective years. We believe a
substantial portion of our sales to Power Digital Card and Macrotron Systems in 2006, 2005 and 2004 are
included in Lexar Media’s products and that such indirect and direct sales to Lexar Media amounted up to 8% of
our net sales in 2006, up to 18% in 2005 and up to 35% of our net sales in 2004.

The majority of our customers purchase our products through purchase orders, as opposed to entering into
long-term contracts with us. The price for our products is typically agreed upon at the time a purchase order is
placed.

Sales and Marketing

We market and sell our products worldwide through a combination of direct sales personnel and

independent distributors. We have direct sales personnel in Taiwan and the United States. Our direct sales force
is divided into two groups that focus on retail and OEM and ODM opportunities, respectively. Approximately
72% of our sales in 2006 were attributable to our direct sales force while the remainder was attributable to
independent distributors. As of December 31, 2006, we had 84 persons on our sales and marketing team,
including 43 in Taiwan and 7 in the United States, and 34 persons on our after-sales support team in China,
Japan, Korea and Germany. We intend to increase our sales efforts in order to expand our OEM and ODM
customer base.

Our marketing group focuses on our product strategy, product road map, new product introduction process,

demand assessment and competitive analysis. Our marketing group is responsible for promoting our products and
solutions by actively participating in industry tradeshows and technical conferences, and maintaining close
contact with our existing customers to assess demand and keep current with industry trends. We seek to work
with potential and existing customers early in their design process in order to best match our products to their
needs. We also provide field application support and assistance to existing and potential customers in designing,
testing and qualifying systems that incorporate our products.

We are also actively involved in both the MMCA and the SDCA, which enable us to keep abreast of the
latest developments in the flash memory card industry and promote our brand name. Our marketing group works
closely with our sales and research and development groups to align our product development road map with the
interests of our customers, both existing and potential. Our marketing group also works with our sales team to
identify new business opportunities.

Research and Development

We devote a significant amount of resources in research and development to broadening and strengthening
our portfolio of product offerings. Our engineering team has expertise in system architecture, IC design, digital
and mixed-signal design and software engineering. As of June 20, 2007, we had 60 patents in China, Japan,

24

Taiwan, Korea, and the United States, with approximately 191 full-time engineers focused in our research and
development efforts and technical services support. These included 29 engineers in application-specific
integrated circuits, 28 in systems engineering, 53 in firmware, 6 in software, 32 in laboratory and 43 in digital
signal processing, computer-aided design, place and route, applications engineering and product engineering. Our
research and development expenses were approximately NT$238.5 million, NT$373.5 million and NT$502.2
million (US$15.4 million) for the years ended December 31, 2004, 2005 and 2006, respectively. Our products-
focused engineering offices are located in Hsinchu and Taipei, Taiwan, Seoul, South Korea, Shanghai, China and
Milpitas, California. Our research and development efforts in the United States are mostly focused on embedded
graphics products, while our research and development efforts in Asia are focused on mobile storage and other
products.

Manufacturing

We design and develop our products and electronically transfer our proprietary designs to independent

foundries for the manufacturing and processing of silicon wafers. Once the wafers are manufactured, they are
then shipped to third-party assembly and testing subcontractors. Individual dies on each wafer are assembled into
finished ICs and undergo several stages of testing before delivery to our customers. We also ship bare dies to our
customers. We believe that our strategy of outsourcing wafer fabrication, packaging and testing enables us to
benefit from the research and development efforts of leading manufacturers without the requirement to commit
substantial capital investments. Our fabless business model also provides us with the flexibility to engage
vendors who offer services that best complement our products and technologies.

Wafer fabrication. UMC in Taiwan and SMIC in China are currently our primary foundries that

manufacture most of our semiconductors. These foundries currently fabricate our devices using mature and stable
CMOS process technology with line-widths of 0.16-, 0.18-, 0.25- and 0.35-micron. We also rely on
STMicroelectronics as our foundry for mobile communications products using Bi-CMOS process technology.
We regularly evaluate the benefits and feasibility, on a product-by-product basis, of migrating to more cost
efficient manufacturing process technologies.

Assembly and testing. Following wafer fabrication, our wafers are shipped to our assembly and test
subcontractors where they are probed, singulated into individual die, assembled into finished IC packages, and
undergo the process of electronic final testing. In order to minimize cost and maximize turn-around time, our
products are designed to use low cost, industry standard packages and can be tested with widely available
automatic test equipment. We currently engage companies such as King Yuan Electronics, SPIL, and Youngtek
Electronics in Taiwan and Amkor in Korea as our primary subcontractors for the assembly and testing of our
products. We have dedicated teams of manufacturing engineers who maintain control over the process from the
early stages of manufacturing. Our engineers work closely with our subcontractors to develop product testing and
packaging programs to ensure these programs meet our product specifications, thereby maintaining our
ownership of the functional and parametric performance of our semiconductors.

Quality and Reliability Assurance. We have designed and implemented a quality assurance system that
provides the framework for continual improvement of products, processes and customer service. To ensure
consistent product quality, reliability and yield, our quality assurance teams perform reliability engineering,
quality control, ISO system development, document control, subcontractor quality management and customer
engineering services to closely monitor the overall process from IC design to after-sale customer support. In
particular, we rely on in-depth simulation studies, testing and practical application testing to validate and verify
our products. We emphasize a strong supplier quality management practice in which our manufacturing suppliers
and subcontractors are pre-qualified by our quality assurance teams. Our suppliers are required to have a quality
management system, certified to ISO 9000 standard. Our operations have been ISO 9001 certified since
November 18, 1999.

25

Competition

The semiconductor industry is characterized by intense competition. Our customers face supply shortages or

oversupply, rapid technological changes, evolving industry standards and declining average selling prices.

We currently compete with other companies that produce flash memory storage controllers, such as Alcor
Micro, Chipsbank, Genesys, Incomm, Phison, Samsung, Skymedi, and USBest. We may also face competition
from some of our customers who may develop products or technologies internally that compete with our
solution. For multimedia SoC products, the companies with whom we compete include Actions, ALi, AMD,
NVIDIA, Rockchip, SigmaTel, and Vimicro. For mobile communications products, the companies with whom
we compete include Analog Devices, Infineon, NXP, Qualcomm, RFMD and Skyworks.

Intellectual Property

To protect our proprietary rights, we rely upon a combination of copyright, patent and trademark laws, laws
relating to protection of other intellectual property rights, trade secrets, and confidentiality agreements with both
employees and third parties. All of our employees have executed confidentiality and assignment agreements that
assign and transfer any rights they may have over information developed in the course of their employment to us.
In addition, prior to disclosing our confidential information and technologies to outside parties, we typically
require that the parties enter into a non-disclosure agreement with us.

As of June 20, 2007, we held 16 patents in Taiwan, 24 patents in the United States, 4 patents in China, 12

patents in Korea, and 4 patents in Japan, relating to various flash management, USB application and other
technologies. These patents will expire at various dates from 2007 through 2025. As of June 20, 2007, we also
had a total of 19 pending patent applications in Taiwan, 27 in the United States, 10 in China and 7 in Japan and
15 in Korea. In addition, we have registered “Silicon Motion” and its logo (a three-dimensional cube depiction of
the letters “SM”) as trademarks in Taiwan and the United States and have made application in China and Japan to
register the mark. FCI, the FCI logo, airRF, basicRF, ezRF, ezSYS, powerRF, twinRF, zipRF and zipSYS are
also our trademarks or registered trademarks.

We typically enter into license agreements with relevant third parties under which we produce our products.
Such third parties include intellectual property vendors such as computer aided design tool vendors and software
vendors.

We expect to continue to file patent applications where appropriate to protect our proprietary technologies.
We applied for 36 patents in 2006 and intend to apply for at least five patents in 2007. We may need to enforce
our patents or other intellectual property rights, or to defend ourselves against claimed infringement of the rights
of others through litigation, which could result in substantial costs and a diversion of our resources and of our
efforts to procure other intellectual property rights. See Item 3 — “Risk Factors — Risks Related to Our
Business — Failure to protect our proprietary technologies or maintain the right to certain technologies may
negatively affect our ability to compete.”

As of December 31, 2006, we had 361 employees, including 235 in Taiwan, 31 in the United States, 88 in

China, and 7 in Japan and Korea.

We do not have any collective bargaining arrangements with our employees. We consider our relations with

our employees to be good.

In November 2004, SMI Taiwan established an employee share option plan under which SMI Taiwan could

issue options in respect of a maximum of 8,000 units, each unit comprising 1,000 common shares in the capital
of SMI Taiwan. After the establishment of the plan, options in respect of a total of 4,000 units, or 4,000,000
shares, were issued. Each option is valid for six years and exercisable under a vesting schedule commencing from
the second year after issuance. In connection with the share exchange between us and the shareholders of SMI
Taiwan that we completed on April 25, 2005, we have agreed to assume these options so that they became
options to purchase the equivalent number of our ordinary shares based on the one-for-one ratio in the share
exchange. Subsequently on June 3, 2005, the Company amended the Plan such that options under the Plan are
granted at an exercise price not lower than the market value of the Company’s ordinary shares at the date of the
grant and vest over four years at certain percentages after one year from the date of grant.

SMI Taiwan has a defined pension plan for all regular employees. This plan provides benefits based on the

length of services and average monthly salary computed based on the final six months of employment. SMI
Taiwan currently makes monthly contributions, equal to 2% of salaries, to a pension fund for its employees.
Under the Labor Pension Act of Taiwan, which went into effect beginning July 1, 2005, eligible employees may
elect to be subject to the pension mechanism under this act, which would require SMI Taiwan to contribute at
least 6% of each employee’s monthly salary.

Facilities

Our headquarters in Taiyuan Science Park, Jhubei City, Hsinchu County, Taiwan, consisting of our finance,
administration, human resource, MIS (IT), operations, research and development and management departments,
is located in a leased space of approximately 37,500 square feet. We lease the premises under a two-year term
lease, expiring February 28, 2008, and a three-year lease, expiring March 15, 2008. We also lease premises in
Taipei, Taiwan, which occupies approximately 24,000 square feet under a one-year lease, expiring May 31, 2008
and a two-year lease, expiring November 30, 2008; in Milpitas, California, under a five-year lease, commencing
April 1, 2007 and expiring March 31, 2012, which occupies approximately 12,000 square feet; in Shanghai,
China, under a two-year lease, expiring May 7, 2008, which occupies approximately 15,900 square feet; in

feet; in Shin-Yokohama, Japan, under a two-year lease, expiring March 25, 2007, and which occupies
approximately 1,500 square feet; and in Seoul, Korea, under a two-year lease, expiring February 27, 2009, and
which occupies approximately 1,300 square feet.

We conduct research and development pertaining to our products at our facilities in Taiwan, China, and
California. We implement our sales and marketing initiatives through our sales offices located in Taiwan, China,
Korea, Japan and California.

With our recent acquisition of FCI, we also have additional operating facilities in Korea, China and
California. The facilities in Seoul, Korea, which houses our mobile communications business management,
research and development, sales, operations, finance and other functions, is an approximately 22,677 square feet
leased premise under a three-year lease, expiring August 9, 2008. FCI also leases a small office in San Jose,
California which houses a sales function and maintain a representative office in Beijing, China with sales and
engineering support and a design team.

We own commercial property in Sizhi, Taipei, Taiwan of approximately 6,000 square feet, which is

currently not used and which we have leased out as office premises.

We believe that adequate facilities are available to accommodate our future expansion plans.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The following discussion of our financial condition and results of operations is based upon and should be
read in conjunction with our consolidated financial statements and their related notes included in this annual
report. This discussion contains forward-looking statements that involve risks and uncertainties. We caution you
that our business and financial performance are subject to substantial risks and uncertainties. Actual results
could differ materially from those projected in the forward-looking statements. In evaluating our business, you
should carefully consider the information provided under the caption “Risk Factors” included in Item 3 of this
annual report.

Principal Factors Affecting Our Results of Operations

Net sales. Our net sales consist primarily of sales of our semiconductors, after deducting sales discounts and

allowances for returns. We have achieved significant sales growth since our inception, primarily due to
significant increases in the number of semiconductors we have sold, offset partially by the lower average selling
prices of each type of semiconductor. We compete primarily in the markets for controllers for flash-based storage
products and multimedia SoCs. Our products primarily consist of controllers for flash memory cards, USB flash
drives and flash card readers, and SoCs for MP3 players, embedded graphics applications, and PC cameras. Net
sales generated by these product groups for the periods indicated were as follows:

Includes controllers for flash memory cards, USB flash drives and flash card readers.
Includes multimedia display processors and portable audio SoCs. We began shipping our portable audio
SoCs in the first quarter of 2005.
Includes primarily demo boards.

We market and sell our products worldwide through a combination of direct sales personnel focusing on
sales to ODMs and OEMs that tend to purchase in higher volumes, as well as through independent distributors
focusing on customers that generally purchase in smaller volumes. We have direct sales personnel in Taiwan and
the United States. Most of our controllers for mobile storage products are sold to large customers who tend to
buy in higher volumes, and therefore we sell most of these products through our direct sales personnel (83% and
79% for the years ended December 31, 2005 and 2006, respectively), with a smaller portion sold through
independent distributors (17% and 21% for the years ended December 31, 2005 and 2006, respectively). Most of
our multimedia SoCs such as multimedia display processors are sold through independent distributors (75%
and77% for the years ended December 31, 2005 and 2006, respectively), as our multimedia display processors
are mainly sold to a broader group of customers who tend to buy in smaller volumes.

In determining whether to sell directly or through distributors, we consider, among other factors, our
experience in those particular markets, creditworthiness of customers, our ability to identify customers, extent of
volume demand in the market and our ability to provide technical support easily in the market.

28

For the years ended December 31, 2004, 2005 and 2006 we derived approximately 59%, 59%, and 58%,

respectively, of our net sales from customers located in Taiwan and approximately 31%, 19%, and 10%,
respectively, of our net sales from customers located in the United States. We anticipate that a majority of our net
sales will continue to come from customers located outside of the United States. The percentages of our net sales
by geographic area for the periods indicated were as follows:

The length of our sales cycle, from the day purchase orders are received until products are shipped to
customers, is dependent on the availability of our product inventories. If we do not have sufficient inventories on
hand to meet customer demands, it generally requires approximately three months from the day purchase orders
are received until finished goods are manufactured and shipped to customers. This cycle can take up to six
months during times when capacity at independent foundries is being fully utilized. The potential delays inherent
in the manufacturing process increase the risk that we may not be able to fulfill a customer’s order on time. All of
our sales are made by purchase orders. Because our practice, which is consistent with industry practice, allows
customers to reschedule orders on relatively short notice, order backlog may not be a good indicator of our future
sales.

Because many of our semiconductor solutions are designed for the multimedia consumer electronics market

such as flash-based storage products, MP3 players and PC cameras, we expect our business to be subject to
seasonality, with increased net sales in the second half of each year, when customers place orders to meet
increased demand for year-end holiday seasons, and generally, decreased net sales in the first half of each year.
However, our recent rapid sales growth makes it difficult for us to assess the impact of seasonal factors on our
business.

Cost of sales. Our cost of sales consists primarily of the following costs:

•

•

•

•

•

cost of wafer fabrication;

assembly, testing and shipping costs of our semiconductors;

personnel and equipment costs associated with manufacturing support;

quality assurance and occupancy costs paid to third-party manufacturers; and

cost of raw materials, for example, SDRAM used with our graphics processors.

We engage independent foundries for the manufacturing and processing of our semiconductors. Our

manufacturing cost is subject to the cyclical supply and demand conditions typical of the semiconductor industry.
Our cost per wafer generally fluctuates with the availability of capacity at independent foundries. We believe that
our cost of sales is substantially variable in nature, and will likely fluctuate as market conditions in the
semiconductor industry change.

29

Research and development expenses. Our research and development expenses consist primarily of employee

salaries and contractor costs, stock-based compensation expense, fees paid for the use of intellectual properties
and design tools developed by third parties, development cost of software, expenses for the design, development
and testing of system architecture, new product or product alternatives, costs for the construction of prototypes,
occupancy costs and depreciation on research and development related equipment. We expense research and
development expenditures as they are incurred. We expect research and development expenses to increase in
future periods in absolute terms as we continue to broaden and strengthen our product portfolio.

Sales and marketing expenses. Our sales and marketing expenses consist primarily of employee salaries and
related costs, stock-based compensation expense, commissions paid to independent distributors and costs for our
advertising and promotional activities. We expect that our sales and marketing expenses will increase in absolute
terms over the next several years. However, we believe that as we continue to achieve scale and greater operating
efficiencies, our sales and marketing expenses may over time decline as a percentage of our net sales.

General and administrative expenses. Our general and administrative expenses consist primarily of general

employee salaries and related costs, stock-based compensation expense, insurance premiums, professional fees
and allowance for doubtful accounts. We expect that general and administrative expenses will increase in
absolute terms in future periods as we continue to expand our operations, and as a result of the increased costs
necessary to comply with the legal and regulatory requirements applicable to publicly listed companies in the
United States.

Accounting for stock-base compensation. The SFAS No. 123(R) was adopted on January 1, 2006. We

recognize stock compensation expense over the requisite service period of the individual grantees, which
generally equals the vesting period.

We elected the modified prospective application method for adopting SFAS No. 123(R). Under this method,

the unrecognized expense of awards not yet vested at January 1, 2006, the date of adoption is recognized in net
income in the periods after the date of adoption using the same Black-Scholes valuation method and assumptions
determined under the original provisions of SFAS No. 123, “Accounting for Stock-Based Compensation,” as
disclosed in our previous annual report.

Non-operating income and expenses. Our non-operating income and expenses include our gains or losses on

the sales of our investment, our interest from deposited cash or short-term investments, our gains or losses on
foreign exchange rates, our impairment of any long-term investments, our interest paid on capital leases and
other non-operating income and expenses not categorized above. We conduct an assessment on the value of our
long-term investments annually, generally at the end of every fiscal year, and make corresponding adjustments as
needed to the value of our long-term investments.

Provision for income taxes. We accrue income taxes at the applicable statutory rates in accordance with the

jurisdictions where our subsidiaries are located and as adjusted for certain items including accumulated losses
carried forward, non-deductible expenses, research and development tax credits, certain tax holidays, as well as
changes in our deferred tax assets and liabilities and related valuation allowance. Furthermore, Taiwan tax
regulations require our Taiwan subsidiary to pay an additional 10% tax on unappropriated earnings. The Taiwan
government enacted the Alternative Minimum Tax Act (the AMT Act), which became effective on January 1,
2006. The alternative minimum tax (AMT) imposed under the AMT Act is a supplemental tax levied at a rate of
10% which is payable if the income tax payable determined pursuant to the Income Tax Law is below the
minimum amount prescribed under the AMT Act. In addition, Taiwan law offers preferential tax treatments to
industries that are encouraged by the Taiwan government. These preferential tax treatments include five-year tax
exemptions for income attributable to expanded production capacity or newly developed technologies funded in
whole or in part by proceeds from initial capital investments made by our shareholders, or subsequent capital
increases, or capitalization of our retained earnings. Such tax exemptions may be available either to the
shareholders of a company, or, if the shareholders so determine, to the company itself. SMI Taiwan has filed

30

three applications for such tax exemptions as SMI Taiwan had used the proceeds of the share offerings it
received in 2002, 2003 and 2004 to fund eligible research and development projects. In the first quarter of 2005,
SMI Taiwan received (a) all approvals, including shareholders’ consent for tax exemptions in connection with
research and development projects using funds raised in 2002, which exemptions have become effective as of
January 1, 2005; (b) the preliminary approval and shareholders’ consent for tax exemptions in connection with
research and development projects using funds raised in 2003, and (c) the preliminary approval for tax
exemptions in connection with research and development projects using funds raised in 2004. We intend to let
SMI Taiwan enjoy the tax exemptions in connection with research and development projects using funds raised
in 2004. Once all the required governmental approvals and shareholders’ consents are received for particular
research and development projects, SMI Taiwan will be entitled to tax exemptions for income derived from
products using technologies from such projects for five years, starting from the fiscal year determined by SMI
Taiwan in accordance with relevant regulations. With a combination of tax credits and exemptions, we expect
our effective tax rate to be lower than the statutory tax rate, so long as we are able to continue to take advantage
of the Taiwanese government’s favorable tax policies. See “Risk Factors — Risks Related to Our Business —
Our business depends on the support of the Taiwanese government, and a decrease in this support may increase
our tax liabilities and decrease our net income” for the risks related to our ability to enjoy favorable tax policies
of the Taiwanese government.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our financial
statements, which have been prepared in accordance with accounting principles generally accepted in the United
States.

The preparation of our consolidated financial statements requires us to make estimates and judgments that

affect the reported amount of assets, liabilities, net sales and expenses, and related disclosure of contingent assets
and liabilities. We evaluate our estimates on an on-going basis, including those related to product returns and
pricing allowances, allowances for doubtful accounts, inventories, long-lived assets, income taxes, litigation and
contingencies. We base our estimates and judgments on our historical experience, knowledge of current
conditions and our beliefs of what could occur in the future considering available information. Because our
estimates may vary in each situation, our actual results may differ from our estimates under different assumptions
and conditions.

Our management considers the following factors in reviewing our financial statements:

•

•

the selection of critical accounting policies; and

the judgments and other uncertainties affecting the application of those critical accounting policies.

The selection of critical accounting policies, the judgments and other uncertainties affecting the application
of those policies and the sensitivity of reported results to changes in conditions and assumptions are factors to be
considered when reviewing our financial statements. Our principal accounting policies are set forth in detail in
Note 2 to our consolidated financial statements included elsewhere in this annual report.

We believe the following critical accounting policies affect our more significant judgments used in the

preparation of our financial statements.

Revenue recognition. Revenue from product sales are generally recognized upon shipment to the customer
provided that we have received a signed purchase order, the price has been fixed or is determinable, transfer of
title has occurred in accordance with the shipping terms specified in the arrangement with the customer,
collectability from the customer is considered reasonably assured, product returns are reasonably estimable and
there are no remaining significant obligations or customer acceptance requirements.

31

We record reserves to cover the estimated returns from our customers. Certain of our distributors have
limited rights of return and price protection rights on unsold inventory. The return rights are generally limited to
five percent of the monetary value of products purchased within the preceding six months, provided the
distributor places a corresponding restocking order of equal or greater value. The allowance for sales returns for
distributors and all customers is recorded at the time of sale based on historical returns information available,
management’s judgment and any known factors at the time the financial statements are prepared that would
significantly affect the allowance. However, because of the inherent nature of estimates, actual returns and
allowances could be significantly different from our estimates. To the extent rates of return change, our estimates
for the reserves necessary to cover such returns would also change which could have a negative impact on our
recorded revenue and gross margin. For the years ended December 31, 2004, 2005, and 2006, our allowance for
sales returns was approximately NT$16.8 million, NT$18.1 million and NT$ 35.1million (US$1.1 million),
respectively, representing approximately 1.0%, 1.0% and 1.0% of our gross sales for those respective periods.

Occasionally, we have reduced our product pricing due to market conditions, competitive considerations and

other factors. Price protection rights are granted to certain distributors under our distribution agreements. When
we reduce the price of our products, it allows the distributor to claim a credit against its outstanding accounts
receivable balances based on the new price of the inventory it has on hand as of the date of the price reduction. A
reserve for price adjustments is recorded at the time of sale based on our historical experience. During 2006, we
incurred actual price adjustments to distributors of approximately NT$512 thousand (US$16 thousand).

Allowance for doubtful accounts. We record an allowance for doubtful accounts based on our evaluation of

the collectability of our accounts receivable. Normal payment terms are provided to customers and apply upon
transfer of title. On an ongoing basis, we analyze the payment history of customer accounts, including recent
customer purchases. In circumstances where we are aware of a specific customer’s inability to meet its financial
obligations to us, we record a specific allowance against amounts due to reduce the net recognized receivable to
the amount we reasonably believe will be collected. For all other accounts receivable due from customers, we
categorize accounts receivables and make provisions based on a percentage of each category. We determine these
percentages by examining our historical collection experience and current trends in the credit quality of our
customers as well as our internal credit policies. If the financial condition of our customers, or economic
conditions in general, were to deteriorate, additional allowances may be required in the future and such additional
allowances would increase our operating expenses and therefore reduce our operating income and net income.

As of December 31, 2005 and 2006 our allowance for trade-related doubtful accounts was approximately
NT$6.0 million and NT$19.6 million (US$0.6 million), respectively, both representing approximately 1.0% of
our gross accounts receivables as of those respective dates. In 2006, we also wrote-off a NT$40.0 million
(US$1.2 million) non-trade related receivable, the collection of which we believe is doubtful.

Inventory valuation. We value inventories at the lower of cost or market value which represents the
replacement cost for raw materials and net realizable value for finished goods and work in process. We write
down our inventory for estimated obsolescence or unmarketable inventory in an amount equal to the difference
between the cost of inventory and the estimated market value based upon assumptions about future demand and
market conditions. If actual market conditions are less favorable than those we projected, additional inventory
write-downs may be required. Inventory impairment charges establish a new cost basis for inventory and charges
are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are
recoverable. In estimating our reserves for obsolescence, we primarily evaluate estimates based on the timing of
the introduction of our new products and the quantities remaining of our old products and provide reserves for
inventory on hand in excess of the estimated demand.

Valuation of long-lived assets and intangible assets. We evaluate the recoverability of long-lived assets and

intangible assets whenever events or changes in circumstances indicate the carrying value may not be
recoverable. The carrying value of a long-lived asset is considered impaired when the anticipated undiscounted
cash flows from such asset is separately identifiable and is less than the carrying value. If impairment occurs, a

32

loss based on the excess of carrying value over the fair market value of the long-lived asset is recognized. Fair
market value is determined by reference to quoted market prices, if available, or discounted cash flows, as
appropriate. The impairment evaluations and the estimate of fair market value involve management estimates of
assets’ useful lives and future cash flows. Actual useful lives and cash flows could be different from those
estimated by our management. This could have a material effect on our operating results and financial condition.
During 2004 and 2005, we recognized impairment losses of approximately NT$11.7 million and NT$0 million
(US$0 million), respectively, on the intangible assets identified for the acquisition of SMI USA. Factors we
consider that could trigger additional impairment review relate to operating losses, significant negative industry
trends, underutilization of the assets, or significant changes in how we use the assets or our plans for their use.

Accounting for income taxes. In preparing our consolidated financial statements, we are required to estimate

our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual
current tax exposure together with assessing temporary differences resulting from differing treatment of items for
tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included
within our consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be
recovered from future taxable income within the relevant jurisdiction and to the extent we believe that recovery
is not likely, we must establish a valuation allowance. We have provided for a valuation allowance to the extent
we believe that it is more likely than not that the deferred tax assets will not be recovered from future taxable
income. Should we determine that we would not be able to realize all or part of our net deferred tax asset in the
future, an additional allowance for the deferred tax asset would be charged to income in the period such
determination was made.

Litigation and contingencies. From time to time, we have been subject to legal proceedings and claims with
respect to such matters as patents and other actions arising out of the normal course of business, as well as other
matters identified in “Legal Proceedings, Item 8 of this Annual Report.” Our success and future revenue growth
will depend, in part, on our ability to protect our intellectual property. We rely on a combination of patent,
copyright, trademark and trade secret laws, as well as nondisclosure agreements and other methods, to protect
our proprietary technologies. We have been issued patents and may have additional patents in the future;
however, we cannot provide assurance that any patent will be issued as a result of any applications or, if issued,
that any claims allowed will be sufficiently broad to protect our technology. In addition, it is possible that
existing or future patents may be challenged, invalidated or circumvented. It may be possible for a third party to
copy or otherwise obtain and use our products or technology without authorization, develop corresponding
technology independently or design around our patents. Effective copyright, trademark and trade secret
protection may be unavailable or limited in foreign countries. These disputes may result in costly and time
consuming litigation or the license of additional elements of our intellectual property for free.

It is possible that other companies might pursue litigation with respect to any claims such companies purport

to have against us. The results of any litigation are inherently uncertain. In the event of an adverse result in any
litigation with respect to intellectual property rights relevant to our products that could arise in the future, we
could be required to obtain licenses to the infringed technology, pay substantial damages under applicable law,
cease the use and sale of infringing products or to expend significant resources to develop non-infringing
technology. Litigation frequently involves substantial expenditures and can require significant management
attention, even if we ultimately prevail.

We have been or are currently involved in various claims and legal proceedings and have incurred certain
costs associated with defending litigation matters. Periodically, we review the status of each significant matter
and assess the potential financial exposure. If the potential loss from any claim or legal proceeding is considered
probable and the amount can be estimated, we accrue a liability for the estimated loss. Because of uncertainties
related to these matters, accruals are based only on the best information available at the time.

Given the uncertainties associated with litigation, if our assessments prove to be wrong, or if additional

information becomes available such that we estimate that there is a possible loss or possible range of loss

33

associated with these contingencies, then we would record the minimum estimated liability, which could have a
material and adverse effect on our operations, financial condition and cash flows.

Comparison of Year Ended December 31, 2006 to Year Ended December 31, 2005

Net sales. Our net sales for the year ended December 31, 2006 were approximately NT$3,460.5 million

(US$106.2 million) compared to approximately NT$2,686.5 million for the year ended December 31, 2005, an
increase of approximately 29%. The increase in our net sales was primarily due to an increase in net sales from
our mobile storage product, which had increased from 85% of overall net sales in 2005 to 87% of overall net
sales in 2006.

The increase in the net sales of our mobile storage products was due to strong volume demand for our
mobile storage products, especially our controllers for flash memory cards, partially offset by declining average
selling prices. The strong volume demand for our mobile storage products was due in part to the growing demand
for digital multimedia devices that use flash-based storage medium, combined with what we believe to be our
favorable competitive position in the markets that we serve, which we believe is primarily due to our ability to

34

deliver products that are universally compatible, highly efficient and require minimal power consumption at
competitive cost and to provide comprehensive post-sale support services.

For the year ended December 31, 2006, we shipped approximately 160.8 million units of semiconductors for

mobile storage products in total, an increase of approximately 103% from approximately 79.4 million units for
the year ended December 31, 2005. Total unit shipment of our multimedia SoCs for the year ended December 31,
2006 remained unchanged at 1.8 million units with the year ended December 31, 2005.

Cost of sales. Our cost of sales grew to approximately NT$1,612 million (US$49.5 million) for the year
ended December 31, 2006 from approximately NT$1,342.7 million in 2005. Our cost of sales as a percentage of
net sales declined from approximately 50.0% of our net sales in 2005 to 46.6% of our net sales in 2006. Our cost
of sales increased as a result of the increased number of semiconductors sold. However, our cost per unit
declined because of several factors. Our cost per unit declined as we migrated our manufacturing process
technology to smaller geometries which increased the number of dies per silicon wafer and lowered our unit cost.
A second factor was the shift towards shipping a larger percentage of our flash memory controllers in bare die
form. The lack of chip assembly removed a cost component that we had previously passed along to our
customers without much mark-up. A third factor was that wafer prices in general were lower in 2006 than in
2005.

Gross profit. Our gross margin increased to 53.4% for the year ended December 31, 2006 from 50.0% for

the year ended December 31, 2005 due to improvements in our cost of sales.

Research and development expenses. Our research and development expenses increased to approximately

NT$502.2 million (US$15.4 million), or 14.5% of net sales, for the year ended December 31, 2006 from
approximately NT$373.5 million, or 13.9% of net sales, for the year ended December 31, 2005. Several factors
contributed to the 34% increase in research and development expenses. Salary, benefits, rental and compensation
expenses grew as we increased our headcount from 141 to 202 employees in our research and development
group, and also as we started accounting for stock-based compensation in 2006, the amount of which was
NT$37.7 million. Our project expense increased as we continued to invest in card readers, portable audio SoCs
for MP3 players and image processor for PC cameras. We expect research and development expenses to increase
in absolute terms in future periods as we continue to increase our staffing and associated costs to pursue
additional product development opportunities.

Sales and marketing expenses. Our sales and marketing expenses increased to approximately NT$200.5

million (US$6.2 million), or 5.8% of net sales, for the year ended December 31, 2006 from approximately
NT$157.3 million, or 5.8% of net sales, for the year ended December 31, 2005. Several factors contributed to the
28% increase in sales and marketing expenses. Salary, benefits, rental and compensation expenses grew as we
increased our headcount from 47 to 84 employees in our sales and marketing group, and also as we started
accounting for stock-based compensation in 2006, the amount of which was NT$13.5 million. We expect sales
and marketing expenses to increase in dollar amount in future periods as we continue to increase the size of our
operations.

General and administrative expenses. Our general and administrative expenses increased to approximately

NT$219.4 million (US$6.7 million), or 6.3% of net sales, for the year ended December 31, 2006 from
approximately NT$129.1 million, or 4.8% of net sales, for the year ended December 31, 2005. Several factors
contributed to the 70% increase in general and administrative expenses. Salary, benefits, rental and compensation
expenses grew as we increased our headcount from 44 to 64 employees in our general and administrative group,
and also as we started accounting for stock-based compensation in 2006, the amount of which was NT$31.0
million. Our general and administrative expenses also increased because of higher costs necessary to comply
with the legal and regulatory requirements applicable to publicly listed companies in the United States. We
expect our general and administrative expenses to increase in absolute dollars in future periods as we continue to
expand our operations.

35

Write-Off of OtherReceivables. For the year ended December 31, 2006, we wrote-off a NT$40.0 million
(US$1.2 million) non-trade receivable, the collection of which we believed was doubtful. We did not have a
similar write-off for the year ended December 31, 2007.

Interest expense. Our interest expense decreased to approximately NT$33,000 (US$1,013) for the year
ended December 31, 2006 from approximately NT$46,000 for the year ended December 31, 2005. Our interest
expense for 2006 decreased as a result of less capital lease payments under which we rented some of our office
equipment in our US subsidiary.

Gain from litigation settlement. Our dispute with Phison was settled on September 22, 2006 after Phison

paid us NT$3,000 thousand (US$92 thousand).

Foreign exchange gain (loss). For the year ended December 31, 2006, we incurred a foreign exchange loss
of NT$5.2 million (US$0.2 million), compared with a gain of NT$1.8 million for the year ended December 31,
2005. The foreign exchange loss is attributable to the weakening of the exchange rate of the NT dollar as
compared to the U.S. dollar during the period.

Interest income. Our interest income increased to approximately NT$65.2 million (US$2.0 million) for the

year ended December 31, 2006 from approximately NT$26.9 million for the year ended December 31, 2005. Our
interest income increased as a result of increases in our cash and cash equivalent position as well as rising
interest rates.

Income tax expense. Our income tax expense decreased to approximately NT$21.0 million (US$0.6 million)

for the year ended December 31, 2006 from an income tax expense of approximately NT$42.1 million for the
year ended December 31, 2005. Our income tax expense decreased primarily as a result of income tax credit
earned in 2006.

Net income. As a result of the foregoing, our net income increased to approximately NT$947.5 million
(US$29.1 million) for the year ended December 31, 2006 from approximately NT$673.3 million for the year
ended December 31, 2005.

Comparison of Year Ended December 31, 2005 to Year Ended December 31, 2004

Net sales. Our net sales for the year ended December 31, 2005 were approximately NT$2,686.5 million

compared to approximately NT$2,166.7 million for the year ended December 31, 2004, an increase of
approximately 24%. The increase in our net sales was primarily due to an increase in sales volume from our key
products. Net sales from our mobile storage products and multimedia SoCs were approximately 85% and 15%,
respectively, of total net sales for the year ended December 31, 2005.

The increase in our sales volume was due to strong demand for our new mobile storage products, including

our SM263 and SM264 flash memory controllers and SM321 USB 2.0 flash disk drive controller, and for our
multimedia SoCs. The strong demand for our products was due in part to the growing demand for digital media
devices that use flash-based storage medium and for MP3 players, combined with what we believe to be our
favorable competitive position in the markets that we serve. We believe that our favorable competitive position
in the market is primarily due to our ability to deliver products that are universally compatible, highly efficient
and require minimal power consumption at competitive cost and to provide comprehensive post-sale support
services.

For the year ended December 31, 2005, we shipped approximately 79.4 million units of semiconductors for

mobile storage products in total, an increase of approximately 132% from approximately 34.3 million units for
the year ended December 31, 2004. Total unit shipment of our multimedia SoCs increased by approximately
299% from 465,000 units for the year ended December 31, 2004 to 1.8 million units for the year ended
December 31, 2005.

36

Cost of sales. Our cost of sales grew to approximately NT$1,342.7 million for the year ended December 31,

2005 from approximately NT$1,274.4 million in 2004. Our cost of sales was approximately 50.0% of our net
sales in 2005 compared to 58.8% of our net sales in 2004. Our cost of sales increased as a result of the increased
number of semiconductors sold. However, our cost per unit declined as a result of the migration of our
manufacturing process technology to smaller geometries which increased the number of dies per silicon wafer
and lowered our unit cost, and the fact that a larger percentage of our flash memory controllers were shipped in
bare die form, which saved us significant costs associated with packaging.

Gross profit. Our gross margin was 50.0% for the year ended December 31, 2005 compared with 41.2% for
the year ended December 31, 2004. Several factors contributed to the increase in gross margin. We migrated our
manufacturing process technology to smaller geometries, which increased the number of dies per silicon wafer
and lowered our unit cost. A second factor was the shift towards shipping a larger percentage of our flash
memory controllers in bare die form. The lack of chip assembly removed a cost component that we had
previously passed along to our customers without much mark-up. A third factor was that wafer prices in general
were lower in 2005 than in 2004.

Research and development expenses. Our research and development expenses increased to approximately
NT$373.5 million, or 13.9% of net sales, for the year ended December 31, 2005 from approximately NT$238.5
million, or 11.0% of net sales, for the year ended December 31, 2004. Several factors contributed to the 57%
increase in research and development expenses. Salary, benefits, rental and travel expenses grew as we increased
our headcount from 69 to 141 employees in our research and development group. Our project expense increased
as we continued to invest in new versions of our flash memory controllers and USB 2.0 flash disk drive
controllers, portable audio SoCs for MP3 players and image processor for PC cameras. We expect research and
development expenses to increase in absolute terms in future periods as we continue to increase our staffing and
associated costs to pursue additional product development opportunities.

Sales and marketing expenses. Our sales and marketing expenses increased to approximately NT$157.3

million, or 5.8% of net sales, for the year ended December 31, 2005 from approximately NT$141.1 million, or
6.5% of net sales, for the year ended December 31, 2004. Our sales and marketing expenses increased by
approximately 11% from 2004 to 2005 primarily as a result of increases in salary, benefits and office rental
expense arisen from increased headcount as well as higher commission. We expect sales and marketing expenses
to increase in dollar amount in future periods as we continue to increase the size of our operations.

General and administrative expenses. Our general and administrative expenses increased to approximately

NT$129.1 million, or 4.8% of net sales, for the year ended December 31, 2005 from approximately NT$103.3
million, or 4.8% of net sales, for the year ended December 31, 2004. Our general and administrative expenses
increased by approximately 25% as a result of higher professional fees, primarily as a result of our being a public
company, higher travel expense and miscellaneous expenses. We expect our general and administrative expenses
to increase in absolute dollars in future periods as we continue to expand our operations.

Amortization of intangible assets. Our expense relating to amortization of intangible assets decreased to

approximately NT$4.5 million for the year ended December 31, 2005 from approximately NT$17.8 million for
the year ended December 31, 2004. This expense was associated with the annual amortization of intangible assets
relating to our acquisition of SMI USA in August 2002. Our amortization expense was lower in 2005 as a result
of our recognition of impairment charges related to these acquired intangible assets in 2004.

Impairment of intangible assets. The charge for impairment of intangible assets was zero for the year ended

December 31, 2005, compared to NT$11.7 million for the year ended December 31, 2004. During the fourth
quarter of 2004, we determined that impairment of the intangible asset, developed technology, occurred as a
result of a significant decline in expected net sales from the introduction of new consumer products such as
broadband Internet video phones, car navigation systems, and Tablet PCs. As the development and market for
these products did not materialize, the forecasted revenues and cash flows were significantly reduced. We

37

estimated the undiscounted cash flows taking into account the new information and determined that the carrying
value of the developed technology was higher than the estimated cash flows. Accordingly, we reduced the
carrying value of the developed technology to the fair value as determined by the estimated discounted cash
flows.

Interest expense. Our interest expense decreased to approximately NT$46,000 for the year ended
December 31, 2005 from approximately NT$169,000 for the year ended December 31, 2004. Our interest
expense for 2005 decreased as a result of the termination of some capital leases under which we rented some
office equipment in our US subsidiary.

Foreign exchange gain. The foreign exchange gain was due to change in exchange rates decreased from

NT$13.7 million in 2004 to NT$1.8 million in 2005. This increase is attributable to the weakening of the
exchange rate of the NT dollar as compared to the U.S. dollar during the periods.

Interest income. Our interest income increased to approximately NT$26.9 million for the year ended
December 31, 2005 from approximately NT$0.6 million for the year ended December 31, 2004. Our interest
income increased as a result of increases in our cash and cash equivalent position as well as rising interest rates.

Income tax expense. Our income tax expense decreased to approximately NT$42.1 million for the year
ended December 31, 2005 from an income tax expense of approximately NT$133.1 million for the year ended
December 31, 2004. Our income tax expense decreased primarily as a result of the five-year tax exemptions for
income attributable to expanded production capacity or newly developed technologies, starting in 2005.

Net income. As a result of the foregoing, our net income increased to approximately NT$673.3 million for
the year ended December 31, 2005 from approximately NT$268.0 million for the year ended December 31, 2004.

Liquidity and Capital Resources

As of December 31, 2006, we had approximately NT$1,808.0 million (US$55.5 million) in cash and cash

equivalents, approximately NT$1,458.8 million (US$44.8 million) in short-term investments and approximately
NT$65.0 million (US$2.0 million) in refundable deposits for reserving foundry capacity with our manufacturing
partners. We maintain our cash balances in deposits with banks in Taiwan and in money market instruments
offshore. Our short-term investments consist primarily of bond funds that are denominated in NT dollars and
invested primarily in time deposits and Taiwan government and corporate bonds. As of December 31, 2006, we
had an unutilized credit facility of NT$70 million (US$2.1 million) which remains uncommitted, can be used for
many purposes and is subject to annual renewal.

On April 30, 2007, we acquired Future Communications IC, Inc. The final purchase price for the transaction
was approximately US$50 million in cash and US$40 million in our ordinary shares and options to purchase our
ordinary shares. Cash which we paid as part of the purchase price reduced our cash and cash equivalent and
short-term investments by US$50 million.

We believe our existing cash balances and short-term investments, together with cash we expect to be
generated from operating activities, will be sufficient to meet our anticipated cash needs for at least the next 12
months. Our future capital requirements will depend on many factors, including the level of our net sales, the
timing and extent of spending to support product development efforts, the expansion of sales and marketing
activities, the timing of introductions of new products, the costs to ensure access to adequate manufacturing
capacity, the continuing market acceptance of our products and availability of attractive acquisition
opportunities. We could be required, or could elect, to seek additional funding through public or private equity or
debt financing, and additional funds may not be available on terms acceptable to us or at all.

Operating activities.

Our net cash provided by operating activities was approximately NT$596.8 million (US$18.3 million) for

the year ended December 31, 2006, an increase of approximately NT$57.8 million over net cash provided by
operating activities of approximately NT$539.0 million for the year ended December 31, 2005. Our net cash
provided by operating activities increased in 2006 primarily as a result of our higher income from operations, our
increased accounts payable and increased income tax payable and was partially offset by increases in our
accounts receivable.

Investing activities.

Our net cash used in investment activities includes the acquisition of long-term investment and purchase of

properties was approximately NT$425.0 million (US$13.0 million) for the year ended December 31, 2006,
compared to net cash provided by investing activities of approximately NT$1,011.9 million for the year ended
December 31, 2005. Our net cash used in investing activities in 2006 was primarily a result of our investments in
Chipmast and Vastview, and prepayment of construction in progress.

Financing activities.

Our net cash provided in financing activities was approximately NT$59.9 million (US$1.8 million) for the

year ended December 31, 2006, compared to net cash provided by financing activities of approximately
NT$1,278.9 million for the year ended December 31, 2005. Proceeds of NT$38.1 million (US$1.2 million) were
received from the issuance of 1.2 million shares of our common stock upon exercise of employee stock options.
Such proceeds were used for working capital and funding research and development of new products.

Off-balance Sheet Arrangements

We currently do not have any outstanding derivative financial instruments, off-balance sheet guarantees or

arrangements, interest rate swap transactions, or foreign currency forward contracts. We do not engage in any
trading activities involving non-exchange traded contracts.

Inflation and Monetary Risk

The principal markets for our products have been in Taiwan and the United States and we do not believe
that inflation in Taiwan or the United States has had a material impact on our results of operations. The rate of
inflation in Taiwan was approximately 1.6%, 2.3%, and 1.0% for 2004, 2005, and 2006, respectively.

Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements”, which defines fair value,

establishes a framework for measuring fair value in generally accepted accounting principles, and expands
disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measurements, but
brings up guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of
the information. This statement is effective for the Company beginning January 1, 2008. The Company is
currently assessing the potential impact that the adoption of SFAS No. 157 will have on the results of operations
and financial position of the Company, and is not yet in a position to determine such effects.

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension

and Other Post-Retirement Plans — An Amendment of FASB Statements No. 87, 88, 106, and 132R” (SFAS
No. 158). Provisions with respect to the recognition of an asset and liability related to the funded status and the
changes in the funded status to be reflected in comprehensive income are effective for fiscal years ending after
December 15, 2006 and the change in measurement date provisions is effective for fiscal years ending after
December 15, 2008. SFAS No. 158 also requires the measurement date of the plan’s funded status to be the same
as the Company’s fiscal year-end. The Company adopted all requirements of SFAS No. 158 for the year ended
December 31, 2006. Upon the adoption of SFAS No. 158, the Company recognized an increase to accumulated
other comprehensive income of NT$2,100 thousand as of December 31, 2006.

In July 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes,

an interpretation of FASB Statement No. 109” (“FIN No. 48”). FIN No. 48 clarifies the accounting for
uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before
being recognized in the financial statements. It also provides guidance on derecognition, classification, interest
and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for fiscal years
beginning after December 15, 2006 and is required to be adopted by the Company in fiscal 2007. The cumulative
effects, if any, of applying FIN No. 48 will be recorded as an adjustment to retained earnings as of the beginning
of the period of adoption. The Company is currently evaluating the effect that the adoption of FIN No. 48 will
have on the results of operations and financial position of the Company and is not yet in a position to determine
such effects.

In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin (“SAB”)
No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Current Year Misstatements.
SAB No. 108 requires analysis of misstatements using both an income statement (rollover) approach and a
balance sheet (iron curtain) approach in assessing materiality and provides for a one-time cumulative effect
transition adjustment. SAB No. 108 is effective for the Company’s fiscal year 2006 annual financial statements.
The Company believes that there is no impact on the results of operations and financial position of the Company
after adopting SAB No. 108.

In February 15, 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and

Financial Liabilities” (SFAS No. 159). Under this standard, the Company may choose to report financial

40

instruments and certain other items at fair value on a contract-by-contract basis with changes in value reported in
earnings. This selection is irrevocable. SFAS No. 159 provides an opportunity to mitigate volatility in reported
earnings that is caused by measuring hedged assets and liabilities that were previously required to use a different
accounting method that the related hedging contracts when the complex provisions of SFAS No. 133 hedge
accounting are not met. The Company believes that there is no impact on the result of operations and financial
position of the Company after adoption of SFAS No. 159.

corporate governance committee.

Audit Committee. The audit committee is responsible for reviewing the financial information that will be
provided to shareholders and others, reviewing the systems of internal controls that management and the board of
directors have established, appointing, retaining and overseeing the performance of the independent registered
public accounting firm, overseeing our accounting and financial reporting processes and the audits of our

Under Cayman Islands law, our directors have a duty to act honestly, in good faith and with a view to the

best interests of our company. Our directors also have a duty to exercise the care, diligence and skills that a
reasonably prudent person would exercise in comparable circumstances. In fulfilling their duty of care to our
company, our directors must ensure compliance with our memorandum and articles of association.

The functions and powers of our board of directors include, among others:

•

our seven directors is currently subject to reelection at our next annual general meeting of shareholders. All of
our executive officers are appointed by and serve at the discretion of our board of directors.

Limitation on Liability and Other Indemnification Matters

Cayman Islands law and our articles of association allow us to indemnify our directors, secretary and other

incurred by reason of any act done or omitted in the execution of their duties as our directors, secretary and other
officers. Under our memorandum and articles of association, indemnification is not available to any matter in
respect of any fraud, dishonesty, willful misconduct or bad faith which may attach to any of them.

Compensation of Directors and Executive Officers

For the year ended December 31, 2006, the aggregate compensation to our directors and senior executive
officers was approximately NT$ 38.5 million (US$ 1.18 million). In 2006, we granted options to our executive
officers as a group to acquire an aggregate of 610,000 ordinary shares. The options granted to our executive
officers and non-executive directors are subject to the same vesting conditions as our employees.

Service Contracts

We currently do not have service contracts with our directors.

44

Share-based Compensation Plans and Option Grants

In April 2005, our board of directors and shareholder adopted our 2005 Incentive Plan. Our stockholders

approved our Amended and Restated 2005 Incentive Plan (referred to in this report as the “Plan”) at our Annual
General Meeting in August 2006, including an amendment to increase the authorized number of shares available
for issuance under the plan from 10,000,000 shares to 25,000,000 shares. The Plan provides for the grant of stock
options, stock bonuses, restricted stock awards, restricted stock units and stock appreciation rights, which may be
granted to our employees (including officers), directors and consultants.

Share Reserve. The aggregate number of ordinary shares that may be issued pursuant to awards granted

under the Plan will not exceed 25,000,000 inclusive of ordinary shares issuable upon exercise of awards
previously granted under the Silicon Motion, Inc. Guidelines for Issuance and Subscription of Employee Stock
Option, which options we have, subject to the consent of the respective option-holders, agreed to assume in the
share exchange.

The following types of shares issued under the Plan may again become available for the grant of new

awards under the Plan: restricted stock issued under the Plan that is forfeited or repurchased by us prior to it
becoming fully vested; shares withheld for taxes; shares tendered to us to pay the exercise price of an option; and
shares subject to awards issued under the Plan that have expired or otherwise terminated without having been
exercised in full.

Administration. The board of directors will administer the Plan and may delegate this authority to administer

the plan to a committee. Subject to the terms of the Plan, the plan administrator, which is our board of directors
or its authorized committee, determines recipients, grant dates, the numbers and types of stock awards to be
granted and the terms and conditions of the stock awards, including the period of their exercisability and vesting.
Subject to certain limitations, the plan administrator will also determine the exercise price of options granted, the
purchase price for restricted stock and restricted stock units, and, if applicable, the strike price for stock
appreciation rights.

Capitalization adjustments. In the event of a dividend or other distribution (whether in the form of cash,

ordinary shares, other securities, or other property), recapitalization, stock split, reorganization, merger,
consolidation, exchange of our ordinary shares or our other securities, or other change in our corporate structure,
the board of directors may adjust the number and class of shares that may be delivered under the Plan and the
number, class and price of the shares covered by each outstanding stock award.

Changes in control. In the event of a change in control of the company, all outstanding options and other

awards under the 2005 Incentive Plan may be assumed, continued or substituted for by any surviving or
acquiring entity. If the surviving or acquiring entity elects not to assume, continue or substitute for such awards,
the vesting of such awards held by award holders whose service with us or any of our affiliates has not
terminated will be accelerated and such awards will be fully vested and exercisable immediately prior to the
consummation of such transaction, and the stock awards shall automatically terminate upon consummation of
such transaction if not exercised prior to such event.

Amendment and termination. The board of directors may amend (subject to shareholder approval as required
by applicable law), suspend or terminate the Plan at any time. Unless sooner terminated by the board of directors,
the Plan will terminate pursuant to its terms on April 22, 2015.

Share Ownership

Under U.S. securities law, a person is deemed to be a “beneficial owner” of a security if that person has or
shares “voting power,” which includes the power to vote or to direct the voting of such security, or “investment
power,” which includes the power to dispose of or to direct the disposition of such security. A person is also
deemed to be the beneficial owner of any securities of which that person has a right to acquire beneficial

45

ownership within 60 days. Under these rules, more than one person may be deemed a beneficial owner of
securities as to which such person has no economic interest.

There were 131,177,358 of our ordinary shares issued and outstanding as of June 20, 2007. The following
table sets forth information with respect to the beneficial ownership of our ordinary shares as of June 20, 2007,
unless otherwise indicated in the footnotes, by:

Legal Proceedings

On January 2, 2003, O2Micro International Limited, or O2Micro, a Cayman Islands company, filed an
action for a preliminary injunction against SMI Taiwan with the Taiwan Hsinchu District Court. The request for
such preliminary injunction alleged that SMI Taiwan produced and sold products with embedded digital sound
effect control chips that infringed O2Micro’s patent, patent registered number 130953, in Taiwan and asked for
an order prohibiting SMI Taiwan from manufacturing and selling certain products that allegedly infringe
O2Micro’s patent in Taiwan. On February 6, 2003, SMI Taiwan filed an action for a preliminary injunction
against O2Micro denying such allegations and requesting O2Micro not to interfere with SMI Taiwan’s
distribution, manufacturing and business operations in relation to the relevant products. A court-appointed
appraiser completed a report on December 16, 2004 stating that SMI Taiwan’s products raised in the case do not
infringe O2Micro’s patent. The appraiser’s report was submitted to the court. O2Micro’ application for a
preliminary injunction was thus dismissed and O2Micro appealed this case to the Taiwan High Court on
November 28, 2005.

On January 14, 2004, O2Micro filed for a preliminary injunction against SMI Taiwan and Microstar, a
Taiwan customer of SMI Taiwan with the Taiwan Panchiao District Court. The request for injunctive relief asked
for an order prohibiting SMI Taiwan and Microstar from designing, manufacturing, advertising and selling
certain products that allegedly infringe O2Micro’s patent, patent registered number 178290, in Taiwan. On
May 20, 2004, the Taiwan Panchiao District Court issued a preliminary injunctive order prohibiting SMI Taiwan
and Microstar from designing, manufacturing, advertising and selling certain products that allegedly infringe
O2Micro’s patent in Taiwan. SMI Taiwan appealed this case to the Taiwan High Court. The Taiwan High Court
rejected the appeal on March 10, 2005, and SMI Taiwan appealed to the Taiwan Supreme Court. On
November 10, 2005, the Taiwan Supreme Court vacated the Taiwan High Court Ruling and the case was
remanded for further proceedings. The enforcement of such preliminary injunctive order has been withdrawn
upon the deposit with the court by SMI Taiwan of NT$11,506 thousand (US$353 thousand).

47

On February 3, 2004, O2Micro filed an application for a provisional seizure of NT$15 million against SMI
Taiwan with the Taiwan Hsinchu District Court. The application alleged that SMI Taiwan infringed O2Micro’s
patent, patent registered number 130953, in Taiwan. The Taiwan Hsinchu District Court issued a provisional
seizure order and attached some of SMI Taiwan’s assets. Upon placing a deposit of NT$15 million, the Taiwan
Hsinchu District Court has released the enforcement of the provisional seizure order.

On September 24, 2004, O2Micro filed an action against SMI Taiwan with the Taiwan Hsinchu District
Court. The complaint alleges that SMI Taiwan infringed O2Micro’s patent, Taiwan patent registered number
130953, and O2Micro has requested SMI Taiwan to cease and desist the tortuous act and a preliminary
compensation in the amount of NT$3 million (US$92,000). On February 9, 2007, SMI Taiwan and O2Micro
agreed to withdraw this case, as well as all the above-mentioned claims and application. As a result of this
agreement, the management of SMI believes this case will not adversely affect SMI’s operations or financial
condition.

On May 1, 2005, SMI Taiwan incurred a loss on inventory in the possession of subcontractor, Advanced
Semiconductor Engineering Inc., or ASE, due to fire. SMI Taiwan is currently in the claims process with ASE
for an amount exceeding the book value of loss inventory. After consultation with the Company’s outside legal
counsel, the Company believes it is highly probable for the Company to receive reimbursement for the lost
inventory at full book value, and the Company subsequently recorded NT$41,226 thousand (US$1.3 million) of
inventory loss, offset by NT$41,226 thousand (US$1.3million) of fire loss reimbursement, resulting in zero
impact to the earnings for the period. In connection with the inventory loss, the Company also recorded
NT$8,122 thousand (US$249,000) under non-operating expenses for amounts paid to certain customers for
delays in shipment caused by the fire.

On December 12, 2005, SMI Taiwan filed an action against ASE with the Taiwan Taoyuan District Court.

SMI Taiwan alleges that ASE destroyed the wafer which SMI Taiwan had consigned to ASE with the OEM
Agreement between SMI and ASE, and that ASE should pay SMI Taiwan a sum of NT$77,218 thousand
(US$2.4 million) for damages. The Taiwan Taoyuan District Court is currently conducting preparatory
proceeding.

Our management currently believes that the legal proceedings described above, individually or in the
aggregate, will not have a material adverse effect on our financial position or operating results. The litigation and
other claims noted above, however, are subject to inherent uncertainties and management’s view of these matters
may change in the future.

Taxation

United States Federal Income Taxation

The following discussion summarizes certain U.S. federal income tax consequences to a U.S. Holder, as
defined below, who purchases our ADSs and ordinary shares. This discussion assumes that investors will hold
their ADSs or ordinary shares as capital assets (generally, property held for investment). This discussion does not
discuss all aspects of U.S. federal income taxation which may be important to particular investors in light of their
individual circumstances, including investors subject to special taxation, such as:

•

•

•

banks;

dealers in securities or currencies; financial institutions; insurance companies; tax-exempt organizations;

persons holding ADSs or ordinary shares as part of hedging, conversion, constructive sale, straddle or
other integrated transactions;

49

•

•

traders in securities that have elected the mark-to-market method of accounting;

persons who own 10% or more of our ADSs or shares;

• U.S. persons whose “functional currency” is not the U.S. dollar; or

• Non-U.S. Holders (as defined below).

This discussion is based in part on representations by the depositary and assumes that each obligation under

the deposit agreement and any related agreement will be performed in accordance with its terms. Furthermore,
the discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended, or the
Code, and U.S. Treasury regulations, rulings and judicial decisions thereunder as of the date hereof. Such
authorities are subject to change, possibly on a retroactive basis, which may result in U.S. federal income tax
consequences different from those discussed below. This discussion does not attempt to address the
consequences to holders of shares or ADSs who acquired their shares or ADSs through the exercise of an
employee stock option or otherwise as compensation or through a tax-qualified retirement plan.

A U.S. Holder considering an investment in our ADSs or ordinary shares is urged to consult its tax advisor

concerning the U.S. federal, state, local and non-U.S. income and other tax consequences.

A U.S. Holder is a beneficial owner of ADSs or ordinary shares that is a U.S. person. A U.S. person is:

•

•

•

•

a citizen or resident individual of the United States;

a corporation or other entity taxable as a corporation created or organized in or under the laws of the
United States, any state thereof, or the District of Columbia;

an estate the income of which is subject to U.S. federal income taxation, regardless of its source; or

a trust if it is subject to the primary supervision of a court within the United States and one or more U.S.
persons have the authority to control all substantial decisions of the trust or has a valid election in effect
under applicable U.S. Treasury regulations to be treated as a U.S. person.

A beneficial owner of ADSs or ordinary shares that is not a U.S. Holder is referred to herein as a “Non-U.S.

Holder.”

If a partnership or limited liability company treated as a partnership for U.S. federal income tax purposes
holds ADSs or ordinary shares, the tax treatment of a partner or member will generally depend on the status of
the partner or member and the activities of the partnership or such limited liability company. A partner of a
partnership or a member of such a limited liability company holding ADSs or ordinary shares is urged to consult
its tax advisors regarding an investment in our ADSs or ordinary shares.

ADSs. In general, for U.S. federal income tax purposes, a U.S. Holder of ADSs will be treated as the owner

of the underlying ordinary shares that are represented by such ADSs. Deposits and withdrawals of ordinary
shares in exchange for ADSs will not be subject to U.S. federal income taxation.

Distributions on ADSs or ordinary shares. Unless the passive foreign investment company rules, as
discussed below, apply, the gross amount of the distributions in respect of the ADSs or ordinary shares will be
subject to tax as dividend income to the extent of our current and accumulated earnings and profits, as
determined under U.S. federal income tax principles. Subject to certain limitations, dividends paid to
non-corporate U.S. Holders, including individuals, may be eligible for a reduced rate of taxation if we are
deemed to be a “qualified foreign corporation” for U.S. federal income tax purposes and provided that such
holder satisfies certain holding period requirements with respect to the ownership of our ADSs, or ordinary
shares. Subject to the exceptions discussed below, a qualified foreign corporation includes:

•

a foreign corporation that is eligible for the benefits of a comprehensive income tax treaty with the
United States that includes an exchange of information program; and

50

•

a foreign corporation if its stock with respect to which a dividend is paid or its ADSs backed by such
stock are readily tradable on an established securities market within the United States.

The Cayman Islands does not currently have comprehensive income tax treaty with the United States. A
foreign corporation (even if it is described above) does not constitute a qualified foreign corporation if, for the
taxable year in which the dividend is paid or the preceding taxable year, the foreign corporation is or was a
passive foreign investment company. Although we believe that we will be a qualified foreign corporation
because the ADSs will be traded on an established U.S. securities market, no assurance can be given in this
regard. In addition, our status as a qualified foreign corporation may change. A U.S. Holder that exchanges its
ADSs for ordinary shares may not be eligible for the reduced rate of taxation on dividends if the ordinary shares
are not deemed to be readily tradable on an established securities market within the United States.

Dividends will be includable in a U.S. Holder’s gross income on the date actually or constructively received

by the depositary, in the case of ADSs or, in the case of ordinary shares, by such U.S. Holder. These dividends
will not be eligible for the dividends-received deduction generally allowed to U.S. corporations in respect of
dividends received from other U.S. corporations.

To the extent we pay dividends on the ADSs or ordinary shares in a currency other than the U.S. dollar, the
U.S. dollar value of such dividends should be calculated by reference to the exchange rate prevailing on the date
of actual or constructive receipt of the dividend, regardless of whether the foreign currency is converted into U.S.
dollars at that time. If the foreign currency is converted into U.S. dollars on the date of actual or constructive
receipt of such dividends, the tax basis of the U.S. Holder in such foreign currency will be equal to its U.S. dollar
value on that date and, as a result, the U.S. Holder generally should not be required to recognize any foreign
currency exchange gain or loss. Dividends paid in respect of the ADSs or ordinary shares generally will be
treated as income from sources outside the United States.

To the extent that the amount of any distribution exceeds our current and accumulated earnings and profits,
the distribution will first be treated as a tax-free return of capital, causing a reduction in the adjusted basis of the
ADSs or ordinary shares, and the balance in excess of adjusted basis will be taxed as capital gain.

Sale, exchange or other disposition of ADSs or ordinary shares. Unless the passive foreign investment
company rules, as discussed below, apply, upon the sale, exchange or other disposition of ADSs or ordinary
shares a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount
realized upon the sale, exchange or other disposition and the adjusted tax basis of the U.S. Holder in the ADSs or
ordinary shares. The capital gain or loss generally will be long-term capital gain or loss if, at the time of sale,
exchange or other disposition, the U.S. Holder has held the ADS or ordinary share for more than one year. Net
long-term capital gains of non-corporate U.S. Holders, including individuals, are eligible for reduced rates of
taxation. The deductibility of capital losses is subject to limitations. Any gain or loss that a U.S. Holder
recognizes generally will be treated as gain or loss from sources within the United States for U.S. foreign tax
credit limitation purposes.

Passive foreign investment company rules. In general, we will be classified as a passive foreign investment

company for any taxable year in which either (a) at least 75% of our gross income is passive income or (b) at
least 50% of the value (determined on the basis of a quarterly average) of our assets is attributable to assets that
produce or are held for the production of passive income. For this purpose, passive income generally includes
dividends, interest, royalties, rents (other than rents and royalties derived in the active conduct of a trade or
business and not derived from a related person), annuities and gains from assets that produce passive income. If
we own directly or indirectly at least 25% by value of the equity shares of another corporation, we will be treated
for purposes of the passive foreign investment company tests as owning a proportionate share of the assets of the
other corporation, and as receiving directly a proportionate share of the other corporation’s income.

51

We believe, based on our present and projected composition of our income and valuation of our assets, that
we are not currently and, should not in the future, be classified as a passive foreign investment company for U.S.
federal income tax purposes, although no assurance can be given in this regard. Whether we are a passive foreign
investment company for any particular taxable year is determined on an annual basis and will depend on the
composition of our income and assets, including goodwill. The calculation of goodwill will be based, in part, on
the then market value of our capital stock, which is subject to fluctuation. In addition, the composition of our
income and assets will be affected by how we spend the cash we raise in this offering. Accordingly, there can be
no assurance that we will not be classified as a passive foreign investment company in the current or any future
taxable year.

If we are a passive foreign investment company for any taxable year during which a U.S. Holder has an
equity interest in our company, unless the U.S. Holder makes a mark-to-market election as discussed below, such
U.S. Holder will be subject to special tax rules in any future taxable year regardless of whether we are classified
as a passive foreign investment company in such future years with respect to (a) “excess distributions” and
(b) gain from the disposition of stock. Excess distributions are defined generally as the excess of the amount
received with respect to the equity interests in the taxable year over 125% of the average annual distributions
received in the shorter of either the three previous years or a U.S. Holder’s holding period before the taxable year
and must be allocated ratably to each day of the U.S. Holder’s holding period. The amount allocated to the
current taxable year or any year before we became a passive foreign investment company will be included as
ordinary income in a U.S. Holder’s gross income for that year. The amount allocated to other prior taxable years
will be taxed as ordinary income at the highest rate in effect for a U.S. Holder in that prior year and the tax is
subject to an interest charge at the rate applicable to deficiencies in income taxes. The entire amount of any gain
realized upon the sale or other disposition of the equity interests will be treated as an excess distribution made in
the year of sale or other disposition and as a consequence will be treated as ordinary income and, to the extent
allocated to years prior to the year of sale or disposition with respect to which we were a passive foreign
investment company, will be subject to the interest charge described above.

In certain circumstances, instead of being subject to the excess distribution rules discussed above, a U.S.
Holder may make an election to include gain on the ADSs or ordinary shares of a passive foreign investment
company as ordinary income under a mark-to-market method, provided that the ADSs or ordinary shares are
regularly traded on a qualified exchange. Under current law, the mark-to-market election is only available for
ADSs or ordinary shares that are regularly traded within the meaning of U.S. Treasury regulations on certain
designated U.S. exchanges and foreign exchanges that meet trading, listing, financial disclosure and other
requirements to be treated as a qualified exchange under applicable U.S. Treasury regulations. The Nasdaq
National Market is a qualified exchange. The ordinary shares may not be eligible for mark-to-market treatment
under the foregoing rule even if the ADSs otherwise satisfy the applicable requirement.

If a U.S. Holder makes a mark-to-market election, the U.S. Holder will include each year as ordinary
income, rather than capital gain, the excess, if any, of the fair market value of the U.S. Holder’s ADSs or
ordinary shares at the end of the taxable year over such U.S. Holder’s adjusted basis in the ADSs (or ordinary
shares, if applicable) and will be permitted an ordinary loss in respect of the excess, if any, of the adjusted basis
of these ADSs or ordinary shares over their fair market value at the end of the taxable year, but only to the extent
of the net amount previously included in income as a result of the mark-to-market election. A U.S. Holder’s basis
in the ADSs or ordinary shares will be adjusted to reflect any such income or loss amounts. Any gain or loss on
the sale of the ADSs or ordinary shares will be ordinary income or loss, except that this loss will be ordinary loss
only to the extent of the previously included net mark-to-market gain.

If a U.S. Holder owns ADSs or ordinary shares during any year that we are a passive foreign investment

company, the U.S. Holder must file Internal Revenue Service Form 8621.

A U.S. Holder is urged to consult its tax advisor concerning the U.S. federal income tax consequences of an
investment in our ADSs or ordinary shares if we are or become a passive foreign investment company, including
the possibility of making a market-to-market election.

Cayman Islands Taxation

The Cayman Islands currently levy no taxes on individuals or corporations based upon profits, income,

gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no other
taxes likely to be material to our company levied by the Government of the Cayman Islands except for stamp
duties that may be applicable on instruments executed in, or after execution brought within the jurisdiction of, the
Cayman Islands. The Cayman Islands are not party to any double taxation treaties. There are no exchange control
regulations or currency restrictions in the Cayman Islands.

We have, pursuant to Section 6 of the Tax Concessions Law (1999 Revision) of the Cayman Islands,

obtained an undertaking from the Governor-in-Council that:

•

•

no law which is enacted in the Cayman Islands imposing any tax to be levied on profits or income or
gains or appreciation applies to us or our operations; and

the aforesaid tax or any tax in the nature of estate duty or inheritance tax are not payable on our ordinary
shares, debentures or other obligations.

The undertaking that we have obtained is for a period of 20 years from March 1, 2005.

Documents on Display

We have previously filed with the SEC our registration statement on Form F-1 and prospectus under

Securities Act with respect to our ADSs.

We are subject to the periodic reporting and other informational requirements of the U.S. Securities
Exchange Act of 1934, or the Exchange Act. Under the Exchange Act, we are required to file reports and other
information with the SEC. Specifically, we are required to file annually a Form 20-F no later than six months
after the close of each fiscal year, which is December 31. As a foreign private issuer, we are exempt from the
rules under the Exchange Act prescribing the furnishing and content of quarterly reports and proxy statements,
and our officers, directors, and principal shareholders are exempt from the reporting and short-swing profit
recovery provisions of Section 16 of the Exchange Act.

Copies of reports and other information, when so filed, may be inspected without charge and may be

obtained at prescribed rates at the public reference facilities maintained by the Securities and Exchange
Commission at the SEC’s public reference room in Washington D.C. at 100 F Street, N.E., Room 1580,
Washington, D.C. 20549. You can request copies of these documents upon payment of a duplicating fee, by
writing to the SEC. Please call the SEC at 1-800-SEC-0330 for further information on the operation of the public
reference rooms. The SEC also maintains a Website at www.sec.gov that contains reports, proxy and information
statements, and other information regarding registrants that make electronic filings with the SEC using its
EDGAR system.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk. Our exposure to interest risk for changes in interest rates is limited to the interest income

generated by our cash deposited with banks and short-term investments maintained in bond funds. We do not
believe that a 1% change in interest rates would have a significant impact on our operations.

Foreign currency risk. Substantial portions of our net sales and expenses are denominated in currencies

other than the NT dollar. As of Dec 31, 2006, more than 76% of our accounts payable and payables were
denominated in currencies other than the NT dollar, primarily in U.S. dollars. More than 43% of our accounts
receivable were denominated in currencies other than the NT dollar, mainly in U.S. dollars. In 2006, all of our
sales were quoted in U.S. dollars and approximately 56% of our sales quotes were invoiced in NT dollars using
the opening average exchange rate on the day of the sales invoice. In 2006, approximately 87% of our cost of

53

sales and operating expenses were denominated in U.S. dollars. Hypothetically, if the U.S. dollar value had
increased or decreased by 10% against the NT dollar in 2006, our operating income would have increased or
decreased, as the case may be, by approximately 9%, assuming all other factors remain constant. We anticipate
that we will continue to quote substantially all of our sales in U.S. dollars. We do not believe that we have a
material currency risk with regard to the Japanese Yen, Euros, Renminbi, or South Korean Won. We believe any
potential adverse foreign exchange impacts on our operating assets may be offset by a potential favorable foreign
exchange impact on our operating liabilities. We do not utilize foreign exchange derivatives contracts to protect
against the volatility changes in foreign exchange rates. See “Risk Factors—Fluctuations in exchange rates could
result in foreign exchange losses.”

PART II

ITEM 14. MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND THE USE OF

PROCEEDS

The following discussion relates to the initial public offering our ADSs by us and certain selling

shareholders, pursuant to a registration statement on Form F-1 (File No. 333-125673), which was completed on
July 5, 2005. The registration statement was declared effective by the SEC on June 29, 2005.

We received net proceeds (after deducting underwriting discounts and commissions and other expenses

related to the offering) of approximately US$41.1 million from the offering 4,300,000 ADSs, representing
17,200,000 ordinary shares. The selling shareholders received net proceeds (after deducting underwriting
discounts and commissions and other expenses related to the offering) of approximately US$23.4 million from
the offering 2,400,000 ADSs, representing 9,600,000 ordinary shares. We did not receive any proceeds from the
sale of our ADSs by the selling shareholders

The expenses incurred by us in connection with the issuance and distribution of the registered securities

totaled US$5.8 million, including US$4.9 million for underwriting discounts and commissions and US$0.9
million for other expenses. None of the transaction expenses included payments to our directors, executive
officers, persons owning 10% or more of our equity securities or our affiliates. Deutsche Bank Securities, WR
Hambrecht + Co, and Needham & Company LLC were the underwriters for the offering.

From July 5, 2005 through June 29, 2007, we have used the entire net proceeds from our initial public

offering, together with cash flows from operations, as follows:

•

•

•

research and development expenditure of NT$998 million (US$30.6 million)

invested US$3.7 million in our operation in China

partial payment for our US$90 million acquisition of FCI, of which US$50 million was payment in cash

ITEM 15. CONTROLS AND PROCEDURES

See Item 15T below.

ITEM 15T. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We performed an evaluation of the effectiveness of the design and operation of our disclosure controls and
procedures as of December 31, 2006. Disclosure controls and procedures are designed to ensure that the material
financial and non-financial information required to be disclosed in this annual report on Form 20-F and filed with
the SEC is recorded, processed, summarized and reported in a timely manner. The evaluation was performed
with the participation of our key corporate senior management, and under the supervision of our Chief Financial
Officer, or CFO, Riyadh Lai, and our President and Chief Executive Officer, or CEO, Wallace Kou. In designing
and evaluating the disclosure controls and procedures, management recognized that any controls and procedures,
no matter how well designed and operated, can provide only reasonable, rather than absolute, assurances of
achieving the desired control objectives, and management necessarily was required to apply its judgment in
evaluating the cost-benefit relationship of possible controls and procedures. Based on the foregoing, our
management, including our CEO and CFO, concluded that our disclosure controls and procedures were effective.

Management’s Report on Internal Control over Financial Reporting

Our management, including our chief executive officer and chief financial officer, is responsible for
establishing and maintaining adequate internal control over financial reporting, as defined under Exchange Act
Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting is a process designed to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements
for external purposes in accordance with accounting principles generally accepted in the United States. Internal
control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of
records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets,
(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting principles, and that the our receipts and
expenditures are being made only in accordance with appropriate authorizations; and (3) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets
that could have a material effect on the financial statements.

Our management assessed the effectiveness of our internal control over financial reporting as of the end of
the period covered by this annual report based on the criteria set forth in Internal Control-Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Their assessment
included an evaluation of the design of our internal control over financial reporting and testing of the operational
effectiveness of our internal control over financial reporting. Based on that assessment, our management
concluded that as of December 31, 2006 the company’s internal control over financial reporting was effective.

While our management concluded that our internal control over financial reporting was effective, we are in

the process developing and implementing additional internal control policies and procedures, including an
anonymous whistleblower reporting system, more comprehensive internal audit procedures and additional anti-
fraud controls. Management expects these and other additional internal control policies and procedures to be
implemented prior to the end of our 2007 fiscal year.

This annual report does not include an attestation report of our independent registered public accounting

firm regarding internal control over financial report. Management’s report was not subject to attestation by our
independent registered public accounting firm pursuant to temporary rules of the Securities and Exchange
Commission that permit us to provide only management’s report in this annual report.

Changes Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting subsequent to the date of our
most recent evaluation that have materially affected, or are reasonably likely to materially affect, our internal
control over financial reporting.

prior approval of all non-audit services to be performed by our independent auditors. Our audit committee reports
to our board of directors regarding the scope and results of our annual audits, compliance with our accounting
and financial policies and management’s procedures and policies related to the adequacy of our internal
accounting controls.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders
Silicon Motion Technology Corporation

We have audited the accompanying consolidated balance sheets of Silicon Motion Technology Corporation and
its subsidiaries ( the “Company”) as of December 31, 2005 and 2006 and the related consolidated statements of
income, changes in shareholders’ equity and comprehensive income (loss) and cash flows for the years ended
December 31, 2004, 2005 and 2006, all expressed in New Taiwan dollars. These financial statements are the
responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. The Company is not required to have, nor
were we engaged to perform, an audit of its internal control over financial reporting. Our audits included
consideration of internal control over financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the
Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also
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, as well as evaluating
the overall financial statement presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial
position of the Company as of December 31, 2005 and 2006, and the results of their operations and their cash
flows for the years ended December 31, 2004, 2005 and 2006, in conformity with accounting principles generally
accepted in the United States of America.

As described in Note 2 to the consolidated financial statements, the Company adopted Statement of Financial
Accounting Standards No. 123 (R), “Share-Based Payment” on January 1, 2006.

Our audits also comprehended the translation of New Taiwan dollar amounts into U.S. dollar amounts and, in our
opinion, such translation has been made in conformity with the basis stated in Note 3 to the consolidated
financial statements. Such U.S. dollar amounts are presented for the convenience of the readers.

SILICON MOTION TECHNOLOGY CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(In Thousands)

1. ORGANIZATION AND OPERATIONS

Silicon Motion Technology Corporation (“SMTC”, collectively with its subsidiaries the “Company”) is a
holding company incorporated in the Cayman Islands on January 27, 2005. Substantially all of the
Company’s operations are conducted through Silicon Motion, Inc. (“SMI”), a wholly-owned subsidiary of
SMTC, located in Taiwan. The Company is a fabless semiconductor company that designs, develops and
markets universally compatible, high-performance, low-power semiconductor solutions for the multimedia
consumer electronics market. The Company’s semiconductor solutions include controllers used in mobile
storage media, such as flash memory cards and USB flash drives and multimedia systems-on-a-chip, or
SoCs, used in digital media devices such as MP3 players, embedded graphics applications and PC cameras.

SMI was incorporated in Taiwan on April 8, 1997 and its shares were approved for public issuance in
Taiwan in December 1999. SMI’s common stock was traded on the Emerging Stock Market of the Taiwan
GreTai Securities Market from June 27, 2003 to April 18, 2005 when SMI, following shareholder approval,
terminated the quotation of its common shares. On April 25, 2005, shareholders of SMI exchanged an
aggregate of 105,412 thousand shares of common stock of SMI for an aggregate of 105,412 thousand
ordinary shares of SMTC. Therefore, all the shareholders of SMI became the holders of an aggregate of
100% of the outstanding shares of SMTC which in turn became the holder of 100% of the outstanding
shares of SMI. SMI shareholders also approved to revoke SMI’s public company status in Taiwan. Such
revocation was approved by the Securities and Futures Bureau of Taiwan on April 26, 2005.

As a result of the share exchange, 100% of the outstanding shares of SMTC are owned by former
shareholders of SMI. Consequently, the exchange was accounted for as a reverse merger and the
consolidated financial statements of SMTC present the historical results, assets and liabilities of SMI on the
consummation of the reverse merger as if SMI was the acquirer.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements have been prepared in accordance with accounting principles
generally accepted in the United States of America (U.S. GAAP). The consolidated financial statements
include the accounts of SMTC and its wholly-owned subsidiaries. The Company owns 100% of the
outstanding shares in all of its subsidiaries, except for Silicon Motion Hong Kong Limited which the
Company owns 99.99%. All significant intercompany balances and transactions have been eliminated upon
consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management
to make estimates and assumptions that affect certain reported amounts and disclosures. The actual results
could differ from those estimates.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash,
cash equivalents, investment in debt securities and accounts receivable. Cash are deposited with high credit-
quality financial institutions. For accounts receivable, the Company performs ongoing credit evaluations of
its customers’ financial condition and the Company maintains an allowance for doubtful accounts receivable
based upon a review of the expected collectibility of individual accounts.

F-9

The Company’s direct and indirect customers include manufactures, OEMs and ODMs of major flash
memory-based storage products as well as portable digital media devices. Many of the Company’s
customers sell brand name consumer electronics products that include the Company’s products. For flash
memory card, UFD and card reader controllers, the Company’s worldwide customers include companies
such as Lexar Media, Samsung, Sony, STMicroelectronics and Transcend. For the multimedia products, the
Company’s worldwide customers include Advantech, Fuji Xerox, GE, Intel, Kontron, Mattel, Panasonic,
Philips, Sharp, Siemens, Sony, Thomson and Toshiba. For the year ended December 31, 2006, only one of
the Company’s customers individually accounted for greater than 10% of net sales. The Company’s top ten
customers in 2006 accounted for approximately 53% of net sales.

Fair Value of Financial Instruments

The carrying amount of the Company’s financial instruments, including cash and cash equivalents, notes
and accounts receivable and notes and accounts payables approximates fair value due to the short-term
maturity of the instruments. Fair values of short-term investments and long-term investments represent
quoted market prices, if available. If no quoted market prices are available, fair values are estimated based
on discounted cash flow, or other valuation techniques.

Cash Equivalents

The Company considers all highly liquid investments with maturities within three months from the date of
purchase to be cash equivalents.

Short-term Investments

The Company invests its excess cash in bond funds and uses the average cost method for trading securities
and available-for-sale securities when determining their cost basis. In 2005, the Company classified all of its
short-term investments as available-for-sale securities, which are initially recognized at fair value with
subsequent changes in fair value reported as unrealized gain or loss in a separate component of
shareholders’ equity. The Company sold all of its available-for-sale securities on December 31, 2005. In
2006, the Company changed its investment objective and classified all short-term investments purchased
subsequent to December 31, 2005 as trading securities. Trading securities are initially recognized at fair
value, with subsequent changes in fair value recorded in earnings as unrealized gains and losses.

Allowance for Doubtful Receivables

An allowance for doubtful receivables is provided based on a review of the collectibility of accounts
receivables. The Company determines the amount of allowance for doubtful receivables by examining the
historical collection experience and current trends in the credit quality of its customers as well as its internal
credit policies.

Inventories

Inventories are stated at the lower of cost or market value. Inventories are recorded at standard cost and
adjusted to the approximate weighted-average cost at the balance sheet date. Market value represents the
current replacement cost for raw materials and net realizable value for finished goods and work in process.
The Company assesses its inventory for estimated obsolescence or unmarketable inventory based upon
management’s assumptions about future demand and market conditions. In estimating reserves for
obsolescence, the Company primarily evaluates estimates based on the timing of the introduction of new
products and the quantities remaining of old products and provides reserves for inventory on hand in excess
of the estimated demand. Estimated losses on slow-moving items are recognized and included in the
allowance for losses.

F-10

Long-term Investments

Long-term investments wherein the Company does not exercise significant influence are accounted for
under the cost method of accounting. Management evaluates related information in addition to quoted
market prices, if any, in determining the fair value of these investments and whether an other than
temporary decline in value exists. Factors indicative of an other than temporary decline include recurring
operating losses, credit defaults and subsequent rounds of financings at an amount below the cost basis of
the investment. Management periodically weighs all quantitative and qualitative factors in determining if
any impairment loss exists.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Significant additions, renewals and
betterments are capitalized, while maintenance and repairs are expensed as incurred.

Depreciation is computed using the straight-line method over estimated useful lives that range as follows:
buildings — 25 years; machinery and equipment — 3 to 6 years; furniture and fixtures — 3 to 8 years;
software — 1 to 5 years; leasehold improvement — the shorter of the estimated useful life or lease term,
which is generally 2 to 6 years. Depreciation expense recognized for the years ended December 31, 2004,
2005 and 2006 was approximately NT$21,734 thousand, NT$23,906 thousand and NT$ 35,596 thousand
(US$ 1,092 thousand), respectively.

Upon the sale or other disposal of property and equipment, the related cost and accumulated depreciation are
removed from the accounts, and any gain or loss is credited or charged to current income.

Impairment of Long-Lived Assets

The Company evaluates the recoverability of long-lived assets whenever events or changes in circumstances
indicate the carrying value may not be recoverable. The determination of recoverability is based on an
estimate of undiscounted cash flows expected to result from the use of an asset and its eventual disposition.
The estimate of cash flows is based upon, among other things, certain assumptions about expected future
operating performance, growth rates and other factors. Estimates of undiscounted cash flows may differ
from actual cash flows due to, among other things, technological changes, economic conditions, changes to
the business model or changes in operating performance. If the sum of the undiscounted cash flows is less
than the carrying value, an impairment loss is recognized, measured as the amount by which the carrying
value exceeds the fair value of the asset.

Other Assets

Other assets consist of refundable deposits for obtaining foundry capacity, and office leases.

Other Restricted Assets

Other restricted assets consist of deposits required for litigation in the Taiwan courts (Note 16).

Pension Costs

For employees under defined contribution pension plans, pension costs are recorded based on the actual
contributions made to employees’ individual pension accounts. For employees under defined benefit
pension plans, pension costs are recorded based on actuarial calculations.

Revenue Recognition

Revenue from product sales is generally recognized upon shipment to the customer provided that the
Company has received a signed purchase order, the price is fixed or determinable, transfer of title has

F-11

occurred in accordance with the shipping terms specified in the arrangement with the customer,
collectibility from the customer is considered reasonably assured, product returns are reasonably estimable
and there are no remaining significant obligations or customer acceptance requirements.

The Company grants certain distributors limited rights of return and price protection rights on unsold
products. The return rights are generally limited to five percent of the monetary value of products purchased
within the preceding six months, provided that the distributor places a corresponding restocking order of
equal or greater value. An allowance for sales returns for distributors and all customers is recorded at the
time of sale based on historical returns information available, management’s judgment and any known
factors at the time the financial statements are prepared that would significantly affect the allowance. Price
protection rights are based on the inventory products the distributors have on hand at the date the price
protection is offered. A reserve for price adjustments is recorded based on the estimated products on hand at
the distributors and historical experience. The Company incurred actual price adjustments to distributors of
NT$838 thousand, NT$4 thousand and NT$512 thousand (US$16 thousand) during 2004, 2005 and 2006,
respectively.

The Company provides a warranty period of one year for manufacturing defects of its products. Warranty
returns have been infrequent and relate to defective or off-specification parts. The Company estimates a
reserve for warranty based on historical experience and records this amount to cost of sales. For the years
ended December 31, 2004, 2005 and 2006, the Company did not experience significant costs associated
with warranty returns.

Research and Development

Research and development costs consist of expenditures incurred during the course of planned research and
investigation aimed at the discovery of new knowledge that will be useful in developing new products or at
significantly enhancing existing products as well as expenditures incurred for the design and testing of
product alternatives. All expenditures related to research and development activities of the Company are
charged to operating expenses when incurred. Third-party research and development costs are expensed
when the contracted work has been performed or as milestone results have been achieved.

Advertising Expenses

The Company expenses all advertising and promotional costs as incurred. Advertising costs charged to
expense amounted to NT$2,552 thousand, NT$978 thousand and NT$1,270 thousand (US$39 thousand) for
the years ended December 31, 2004, 2005, and 2006, respectively.

Income Taxes

Income taxes are accounted for in accordance with Statement of Financial Accounting Standards (“SFAS”)
No. 109 “Accounting for Income Taxes”. The provision for income tax represents income tax paid and
payable for the current year plus the changes in the deferred income tax assets and liabilities during the
years. Deferred income tax assets are recognized for net operating loss carryforwards, research and
development credits, and temporary differences. The Company believes that uncertainty exists regarding the
realizability of certain deferred income tax assets and, accordingly, has established a valuation allowance for
those net deferred income tax assets to the extent the realizability is not deemed more likely than not.

Under Taiwan tax regulations, the current year’s earnings, on an after tax basis, that are not distributed in
the following year are subject to a 10% additional income tax. This 10% additional income tax is recognized
in the period during which the related earnings are generated.

The R.O.C. government enacted the Alternative Minimum Tax Act (the AMT Act), which became effective
on January 1, 2006. The alternative minimum tax (AMT) imposed under the AMT Act is a supplemental tax

F-12

levied at a rate of 10% which is payable if the income tax payable determined pursuant to the Income Tax
Law is below the minimum amount prescribed under the AMT Act. The taxable income for calculating the
AMT includes most of the income that is exempted from income tax under various laws and statutes. The
Company has considered the impact of the AMT Act in the determination of its tax liabilities.

Foreign Currency Transactions

Foreign currency transactions are recorded at the rates of exchange in effect when the transaction occurs.
Gains or losses, resulting from the application of different foreign exchange rates when cash in foreign
currency is converted into the entities’ functional currency, or when foreign currency receivables and
payables are settled, are credited or charged to income in the period of conversion or settlement. At the
balance sheet date, assets and liabilities denominated in foreign currencies are remeasured based on
prevailing exchange rates and any resulting gains or losses are credited or charged to income.

Translation of Foreign Currency Financial Statements

The reporting currency of the Company is the New Taiwan dollar. The functional currency is the local
currency of the respective entities. Accordingly, the financial statements of the foreign subsidiaries are
translated into New Taiwan dollars at the following exchange rates: assets and liabilities — current rate on
the balance sheet date; shareholders’ equity — historical rates; income and expenses — average rate during
the period. The resulting translation adjustment is recorded as a separate component of shareholders’ equity
in accumulated other comprehensive income.

Comprehensive Income (Loss)

Comprehensive income and loss represents net income plus the results of certain changes in shareholders’
equity during a period from non-owner sources that are not reflected in the consolidated statements of
income.

Legal Contingencies

The Company is currently involved in various claims and legal proceedings. Periodically, the Company
reviews the status of each significant matter and assesses the potential financial exposure. If the potential
loss from any claim or legal proceeding is considered probable and the amount can be estimated, the
Company accrues a liability for the estimated loss. Because of uncertainties related to these matters,
accruals are based only on the best information available at the time. As additional information becomes
available, the Company reassesses the potential liability related to the pending claims and litigation and
revises these estimates as appropriate. Such revisions in the estimates of the potential liabilities could have a
material impact on the results of operations and financial position.

Earnings Per Share

Basic earnings per share are computed by dividing net earnings attributable to common/ordinary
shareholders by the weighted average number of common/ordinary shares outstanding during the period.
Diluted earnings per share reflect the potential dilution that could occur if potential common/ordinary stock
was exercised. Common/ordinary stock equivalents are excluded from the computation of the diluted
income per share in periods when their effect is anti-dilutive. The Company’s common/ordinary stock
equivalent consists only of common/ordinary stocks issuable upon the exercise of employee stock options
(using the treasury stock method).

Stock-Based Compensation

The Company grants stock options to its employees and directors. Prior to January 1, 2006, the Company
accounted for options granted under Accounting Principles Board Opinion (“APB”) No. 25, “Accounting for

F-13

Stock Issued to Employees” and complied with the disclosure requirements of SFAS No. 123, “Accounting for
Stock-Based Compensation”. Under APB No. 25, compensation expense is measured based on the difference,
if any, on the date of the grant, between the fair value of the Company’s stock and the exercise price.

On January 1, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123(R),
“Share-Based Payment,” using the modified prospective application method. In accordance with the
transition method, the Company’s consolidated financial statements for prior periods have not been restated
to reflect, and do not include, the impact of SFAS No. 123(R). The adoption of SFAS No. 123(R) resulted in
incremental stock-based compensation expense of NT$157,475 thousand (US$4,832 thousand). The
incremental stock-based compensation expense caused net income to decrease by NT$85,699 thousand
(US$2,630 thousand) for the year ended December 31, 2006, and basic and diluted earnings per share to
decrease by NT$0.69 and NT$0.60, respectively.

The following pro forma information, as required by SFAS No. 148, “Accounting for Stock-Based
Compensation — Transition and Disclosure, an amendment of FASB Statement No. 123,” is presented for
comparative purposes and illustrates the pro forma effect on net income and related earnings per share for
the year ended December 31, 2005, as if the Company had applied the fair value recognition provisions of
SFAS No. 123 to stock-based compensation for that period.

Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements”, which defines fair value,
establishes a framework for measuring fair value in generally accepted accounting principles, and expands
disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measurements,
but brings up guidance on how to measure fair value by providing a fair value hierarchy used to classify the
source of the information. This statement is effective for the Company beginning January 1, 2008. The
Company is currently assessing the potential impact that the adoption of SFAS No. 157 will have on the results
of operations and financial position of the Company, and is not yet in a position to determine such effects.

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension
and Other Postretirement Plans — An Amendment of FASB Statements No. 87, 88, 106, and 132R” (SFAS
No. 158). Provisions with respect to the recognition of an asset and liability related to the funded status and
the changes in the funded status be reflected in comprehensive income are effective for fiscal years ending
after December 15, 2006 and the change in measurement date provisions is effective for fiscal years ending
after December 15, 2008. SFAS No. 158 also requires the measurement date of the plan’s funded status be
the same as the Company’s fiscal year-end. The Company adopted all requirements of SFAS No. 158 for the
year ended December 31, 2006. Upon the adoption of SFAS No. 158, the Company recognized an increase
to accumulated other comprehensive income of NT$2,100 thousand as of December 31, 2006.

F-14

In July 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes,
an interpretation of FASB Statement No. 109” (“FIN No. 48”). FIN No. 48 clarifies the accounting for
uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before
being recognized in the financial statements. It also provides guidance on derecognition, classification,
interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for fiscal
years beginning after December 15, 2006 and is required to be adopted by the Company in fiscal 2007. The
cumulative effects, if any, of applying FIN No. 48 will be recorded as an adjustment to retained earnings as
of the beginning of the period of adoption. The Company is currently evaluating the effect that the adoption
of FIN No. 48 will have on the results of operations and financial position of the Company and is not yet in
a position to determine such effects.

In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin (“SAB”)
No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Current Year
Misstatements. SAB No. 108 requires analysis of misstatements using both an income statement (rollover)
approach and a balance sheet (iron curtain) approach in assessing materiality and provides for a one-time
cumulative effect transition adjustment. SAB No. 108 is effective for the Company’s fiscal year 2006 annual
financial statements. There was no impact on the results of operations and financial position of the
Company after adopting SAB No. 108.

In February 15, 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and
Financial Liabilities” (SFAS No. 159). Under this standard, the Company may choose to report financial
instruments and certain other items at fair value on a contract-by-contract basis with changes in value
reported in earnings. This selection is irrevocable. SFAS No. 159 provides an opportunity to mitigate
volatility in reported earnings that is caused by measuring hedged assets and liabilities that were previously
required to use a different accounting method that the related hedging contracts when the complex
provisions of SFAS No. 133 hedge accounting are not met. The Company believes that there is no impact on
the result of operations and financial position of the Company after adoption of SFAS No. 159.

Reclassifications

Certain accounts in the consolidated financial statements as of December 31, 2005 and for the years ended
December 31, 2004 and 2005 have been reclassified to conform to the consolidated financial statements as
of and for the year ended December 31, 2006. The Company reclassified compensation to customers from
non-operating expense in 2005 to operating expense in 2006. The Company also reclassified and presented
as separate items on the consolidated balance sheet for deferred income tax assets, net and other restricted
assets, which were included in other assets in 2005.

3. US DOLLAR AMOUNTS

The Company maintains its accounts and expresses its financial statements in New Taiwan dollars. For
convenience only, U.S. dollar amounts presented in the accompanying financial statements have been
translated from New Taiwan dollars, using the U.S. Federal Reserve Bank of New York non-buying rate of
NT$32.59 to US$1 on December 29, 2006. The convenience translations should not be construed as
representations that the New Taiwan dollar amounts have been, could have been or could in the future be,
converted into U.S. dollars at this or any other exchange rate.

In December 2004, the Company recorded an inventory write-off of approximately NT$49,362 thousand to
cost of sales due to production defects associated with the migration from 0.35 micron to 0.18 micron
manufacturing technologies for one of the Company’s products, SM264. A portion of the defects stemmed
from the Company’s use of manufacturing process technology offered free of charge and developed by other
companies. For these defective wafers, the Company sought indemnification from these companies and
received NT$4,968 thousand and NT$19,121 thousand worth of replacement wafers in 2004 and 2005,
respectively, for which the Company valued at the cost of the defective wafers, and such amounts were
recorded as reductions in cost of sales for the years ended December 31, 2004 and 2005, respectively.

In November 2005 and May 2006, the Company invested in Spright’s common stocks. Spright is a
multinational semiconductor assembly and testing company. Spright was formerly known as Flash Media
Corporation.

In November and December 2006, the Company invested in the common stocks of Chipmast and Vastview,
respectively. Chipmast is a semiconductor design and application company and Vastview is the electro —
optical integrated company.

The Company accounts for these investments using the cost method as the Company does not have significant
influence over the investees. These investments are evaluated for impairment on an annual basis or as the
circumstances indicate. No impairment has been recorded for the years ended December 31, 2005 and 2006.

For the year ended December 31, 2004, due to the decline in value of the investment in ARCHIC which the
Company determined to be other than temporary, the Company recorded a loss on impairment of such
investments of NT$4,053 thousand. As of December 31, 2005, ARCHIC was dissolved and NT$1,159
thousand was returned to the Company upon liquidation.

The Company records intangible assets in accordance with SFAS No. 141 “Business Combination” and
SFAS No. 142, “Goodwill and Other Intangible Assets”. The above trademark and developed technology
were acquired during the Company’s acquisition of SMI USA in August 2002.

The Company evaluates long-lived assets held and used by the Company for impairment whenever events or
changes in circumstances indicate that their net book value may not be recoverable in accordance with

F-18

SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”. During the fourth
quarter of 2004, the Company determined that impairment of the intangible assets occurred as a result of a
significant decline in revenue associated with the sales expected to be generated from the introduction of
new consumer products such as the broadband internet video phone, car navigation system, and Tablet PC
as next generation of notebook computers. As the market and the development for these products did not
occur as anticipated, the forecasted revenues and cash flows were significantly impacted. The Company
estimated the undiscounted cash flows taking into account the new information and determined that the
carrying value of the developed technology was higher than the estimated cash flows. Accordingly, the
Company reduced the carrying value of the developed technology to the fair value as determined by the
estimated discounted cash flows. This resulted in an impairment charge of NT$11,718 thousand that was
recorded against intangibles and is included in the consolidated statements of income for the year ended
December 31, 2004.

At December 31, 2005, SMI USA was able to recognize additional tax benefit associated with a valuation
allowance that had been recorded at the purchase date for the related deferred tax assets. Accordingly, the
Company reduced the value of the intangible assets by NT$2,342 thousand to reflect the amount of the tax
benefit.

12. PENSION PLAN

The Labor Pension Act (the “Act”) of Taiwan became effective on July 1, 2005 and the pension mechanism
under the Act is deemed a defined contribution plan. The employees who were subject to the Labor
Standards Law prior to July 1, 2005 were allowed to choose to be subject to the pension mechanism under
the Act or continue to be subject to the pension mechanism under the Labor Standards Law. For those
employees who were subject to the Labor Standards Law prior to July 1, 2005 and still work for the same
company after July 1, 2005 and have chosen to be subject to the pension mechanism under the Act, their
seniority as of July 1, 2005 shall be maintained. The Act prescribes that the rate of contribution by an
employer to employees’ pension accounts per month shall not be less than 6% of each employee’s monthly
salary. The Company made monthly contributions and recognized pension costs of NT$3,476 thousand and
NT$ 8,831 thousand (US$271 thousand) for the years ended December 31, 2005 and 2006, respectively.

The Company has defined benefit plans under the Labor Standards Law of Taiwan that provide benefits
based on years of service and average salary computed based on the final six months of employment. The
law requires companies incorporated in Taiwan to contribute between 2% to 15% of employee salaries to a
government specified plan. SMI’s plan makes monthly contributions equal to 2% of employee salaries to a
government specified pension. Contributions are required to be deposited in SMI’s pension name of the
committee with the Central Trust of China in Taiwan. Future contributions will be based on 2% of the

F-19

employee salaries at that time. The Company estimates its contribution for the year ending December 31,
2007 to be NT$1,800 thousand which was determined based on 2% of estimated salaries in 2007. The
measurement date of the plan is December 31.

The effect of adopting SFAS No. 158 on individual line items in the consolidated balance sheet as of
December 31, 2006 was as follows (in NT$ thousand):

calculated at the Cayman Islands statutory rate of zero for each year.

The Company and its subsidiaries file separate income tax returns. A reconciliation of income tax expense

expire in 2010. In addition, profits generated from certain products are exempted from income tax for five
years beginning January 1, 2005. For the years ended December 31, 2005 and 2006, the Company had
NT$777,851 thousand and NT$915,018 thousand of tax-exempt income, resulting savings on income tax
expense of NT$194,463 thousand and NT$228,755 thousand, respectively. Basic and diluted earnings per
share effects from the savings on income tax expense were NT$1.70 and NT$1.67, and NT$1.86 and
NT$1.82 for the years ended December 31, 2005 and 2006, respectively.

As of December 31, 2006, the Company’s United States federal and state net operating loss carryforwards
for income tax purposes were approximately NT$754,133 thousand (US$23,140 thousand) and NT$384,398
thousand (US$11,795 thousand), respectively. If not utilized, the federal net operating loss carryforwards
will expire in 2021 and the state net operating loss carryforwards will expire in 2012.

As of December 31, 2006, the Company’s United States federal and state research and development tax
credit carryforwards for income tax purposes were approximately NT$57,945 thousand (US$1,778
thousand) and NT$51,655 thousand (US$1,585 thousand), respectively. If not utilized, the federal tax credit
carryforwards will expire in 2021 while the state tax credit carryforward has no expiration date.

Current United States federal and California state laws include substantial restrictions on the utilization of
net operating losses and credits in the event of an “ownership change” of a corporation. Accordingly, the
Company’s ability to utilize net operating loss and tax credit carryforwards may be limited as a result of
such “ownership change”. Such a limitation could result in the expiration of carryforwards before they are
utilized.

SMI income tax returns through 2004 had been examined and cleared by the Taiwan tax authorities.

14. SHAREHOLDERS’ EQUITY

Appropriations from Earnings

Pursuant to the laws and regulations of the ROC and the respective Articles of Incorporation, the
Company’s subsidiary in Taiwan must make appropriations from annual earnings to non-distributable

F-23

reserve which could affect the Company’s ability to pay cash or stock dividends, if any. The Taiwan
subsidiary may only distribute dividends after it has made allowances as determined under ROC GAAP at
each year-end for:

a.

Payment of taxes;

b. Recovery of prior years’ deficits, if any;

c.

d.

10% of remaining balance after deduction for a and b as legal reserve;

Special reserve based on relevant laws or regulations or 10% of remaining balance for deduction from
a to c as special reserve;

e. Cash or stock bonus to employees at 0.01% of any remaining earnings after the above reserves have

been appropriated based on a resolution of the board of directors. If bonus to employees is in the form
of stock, the bonus may also be appropriated to employees of subsidiaries under the board of directors’
approval;

In accordance with the above, SMI paid 15% of the remaining unappropriated earnings for 2004, in the form
of 2,362 thousand shares of common stock, to employees as bonuses in the form of stock. The stock bonuses
were recorded as compensation expense based on NT$31.70 per share which was determined to be the fair
value on the date of shareholder approval. In addition, SMI paid a stock dividend to its shareholders as part
of their respective interests in the accumulated earnings of the Taiwan subsidiary. SMI recorded the
dividend based on the fair value of the stock on the date of shareholder approval which was NT$31.70 per
share.

15. STOCK OPTION PLAN

Stock Option Plan

In 2004, SMI adopted a 2004 Employee Stock Option Plan (“the 2004 Plan”). The 2004 Plan reserved 8,000
units with each unit entitled to subscribe for 1,000 shares of common stock after the requisite service is
rendered. The options may be granted to qualified employees of the Company or any of its domestic or
foreign subsidiaries and expire no later than six years from the date of grant. Generally, the options are
granted at an exercise price not lower than the market value of the SMI’s common stock at the date of the
grant and vest over four years at certain percentages after two years from the date of grant. On
December 31, 2004, 4,000 units were granted to employees at an exercise price of NT$40 (US$1.26) per
share. As part of the share exchange between the Company and the shareholders of SMI effective on
April 25, 2005, the Company agreed to assume the share options previously issued by SMI. Subsequently on
June 3, 2005, the Company amended the 2004 Plan such that options under the 2004 Plan are granted at an
exercise price not lower than the market value of the Company’s ordinary shares at the date of the grant and
vest over four years at certain percentages after one year from the date of grant.

On April 22, 2005, the Company adopted its 2005 Equity Incentive Plan (“the 2005 Plan”). The 2005 Plan
provides for the grant of stock options, stock bonuses, restricted stock awards, restricted stock units and
stock appreciation rights, which may be granted to employees (including officers), directors and consultants.
The 2005 Plan reserved 10,000 thousand shares of ordinary shares, inclusive of the number of assumed
share options under the 2004 Plan, for issuance upon the exercise of stock options.

In 2006, the Company amended the 2005 Plan to reserve additional 15,000 thousand shares of ordinary
shares for issuance upon exercise of stock options.

Adoption of SFAS No. 123(R)

The Company adopted SFAS No. 123(R) effective January 1, 2006. SFAS 123(R) requires the recognition
of the fair value of stock compensation in net income. The Company recognizes stock compensation

F-24

expense over the requisite service period of the individual grantees, which generally equals the vesting
period. Prior to January 1, 2006, the Company followed Accounting Principles Board Opinion 25,
“Accounting for Stock Issued to Employees,” and related interpretations in accounting for stock
compensation. Under the intrinsic value method, no stock-based compensation expense had been recognized
in the Company’s consolidated statements of income, because the exercise price of the Company’s stock
options granted to employees and directors equaled the fair value of the underlying stock at the date of
grant.

The Company elected the modified prospective application method for adopting SFAS No. 123(R). Under
this method, the unrecognized expense of awards not yet vested at January 1, 2006, the date of adoption is
recognized in net income in the periods after the date of adoption using the same Black-Scholes valuation
method and assumptions determined under the original provisions of SFAS No. 123, “Accounting for Stock-
Based Compensation,” as disclosed in the Company’s previous annual report

Stock-based compensation expense recognized during the period is based on the value of the portion of
stock-based payment awards that is ultimately expected to vest during the period. Stock-based compensation
expense recognized in the Company’s consolidated statement of income for the year ended December 31,
2006 includes compensation expense for stock options granted subsequent to December 31, 2005 and stock
options granted before January 1, 2006 but unvested yet. The grant date fair values of those stock options
were determined in accordance with the provision of SFAS No. 123 (R). The Company recognizes these
compensation net of a forfeiture rate for only those awards expected to vest, on a straight line basis over the
requisite service period of the award which is about 3- 4 years. SFAS No. 123(R) requires forfeitures to be
estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ
from those estimates.

The weighted-average-grant date fair value of stock options granted during the years ended December 31,
2004, 2005 and 2006 were US$1.26, US$2.66 and US$3.46, respectively.

F-25

As of December 31, 2006, there was NT$ 184,785 thousand (US$5,670 thousand), net of estimated
forfeitures, of total unrecognized compensation cost related to non-vested share-based compensation awards
granted under the Company’s stock option plans. This cost will be amortized over a weighted average
period of approximately 2.27 years.

The aggregate intrinsic value in the table above represents the total intrinsic value (the difference between
the Company’s closing stock price on the last trading day of fiscal year 2006 and the exercise price,
multiplied by the number of in-the-money options) that would have been received by the option holders had
all option holders exercised their options on December 31, 2006. Intrinsic value will change in future
periods based on the fair market value of the Company’s stock and the number of shares outstanding.

Determining Fair Value

The Company estimated the fair value of each option grant on the date of grant using the Black-Scholes
option pricing model. The Black-Scholes option valuation model was developed for estimating the fair value
of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation
model requires the input of highly subjective assumptions, including the expected stock price volatility. The
Company used the following weighted-average assumptions for each year in calculating the fair value of the
options granted:

Expected dividend yield . . . . . . . . . . . . . .
Expected volatility . . . . . . . . . . . . . . . . . .
Risk free interest rate . . . . . . . . . . . . . . . .

The Company estimated the fair value of each option grant on the date of grant using the Black-Scholes
option pricing model that use the assumptions in the following table. Risk-free interest rate is based on the
U.S. Treasury yield curve in effect at the time of grant. Expected volatilities are based on historical
volatilities of stock prices of companies similar to the Company. Expected term represents the periods that
the Company’s share- based awards are expected to be outstanding and was determined based on historical
experience regarding similar awards, giving consideration to the contractual term of the share-based awards.
The dividend yield is zero as the Company has never declared or paid dividends on the ordinary shares or
other securities and does not anticipate paying dividends in the foreseeable future.

16. COMMITMENTS AND CONTINGENCIES

In 2001, SMI received a subsidy from the ROC Industrial Development Bureau (IDB) for research and
development of controller products and a semiconductor data storage system. The subsidy was in the form
of cash of NT$5,093 thousand and non-interesting bearing loan of NT$5,093 thousand. The non-interesting
bearing loan in eight consecutive quarterly payments and has been totally paid off by the Company in
January 2005. SMI is required to pay the IDB 2% of sales as royalty payments from any products resulting
from the research and development project for a period of three years following the initial sale. Total
royalties paid cannot exceed 30% of the total amount of the subsidy loan amount, or approximately
NT$1,530 thousand. As of December 31, 2006, the Company completed the research and development
project under this agreement; however, the Company has not sold any products using this technology and
therefore has not paid or accrued any royalty payments related to the projects.

As of December 31, 2006, the Company had a credit facility to NT$70 million with China Trust Bank. This
credit facility can be used for multi-purposes and is subject to annual renewal.

F-26

Operating Leases

The Company entered into various operating lease agreements for office space that expire on various dates
through May 2008. The Company recognized rent expense during the years ended December 31, 2004, 2005
and 2006 of NT$18,702 thousand, NT$24,215 thousand and NT$33,673 thousand (US$1,033 thousand),
respectively. The minimum operating lease payments under these leases as of December 31, 2006 were
NT$17,304 thousand and NT$3,377 thousand for the years ending December 31, 2007 and 2008,
respectively.

Litigation

On January 2, 2003, O2Micro International Limited, or O2Micro, a Cayman Islands company, filed an
action for a preliminary injunction against SMI Taiwan with the Taiwan Hsinchu District Court. The request
for such preliminary injunction alleged that SMI Taiwan produced and sold products with embedded digital
sound effect control chips that infringed O2Micro’s patent, patent registered number 130953, in Taiwan and
asked for an order prohibiting SMI Taiwan from manufacturing and selling certain products that allegedly
infringe O2Micro’s patent in Taiwan. On February 6, 2003, SMI Taiwan filed an action for a preliminary
injunction against O2Micro denying such allegations and requesting O2Micro not to interfere with SMI
Taiwan’s distribution, manufacturing and business operations in relation to the relevant products. A court-
appointed appraiser completed a report on December 16, 2004 stating that SMI Taiwan’s products raised in
the case do not infringe O2Micro’s patent. The appraiser’s report was submitted to the court. O2Micro’
application for a preliminary injunction was thus dismissed and O2Micro appealed this case to the Taiwan
High Court on November 28, 2005.

On January 14, 2004, O2Micro filed for a preliminary injunction against SMI Taiwan and Microstar, a Taiwan
customer of SMI Taiwan with the Taiwan Panchiao District Court. The request for injunctive relief asked for
an order prohibiting SMI Taiwan and Microstar from designing, manufacturing, advertising and selling certain
products that allegedly infringe O2Micro’s patent, patent registered number 178290, in Taiwan. On May 20,
2004, the Taiwan Panchiao District Court issued a preliminary injunctive order prohibiting SMI Taiwan and
Microstar from designing, manufacturing, advertising and selling certain products that allegedly infringe
O2Micro’s patent in Taiwan. SMI Taiwan appealed this case to the Taiwan High Court. The Taiwan High
Court rejected the appeal on March 10, 2005, and SMI Taiwan appealed to the Taiwan Supreme Court. On
November 10, 2005, the Taiwan Supreme Court vacated the Taiwan High Court Ruling and the case was
remanded for further proceedings. The enforcement of such preliminary injunctive order has been withdrawn
upon the deposit with the court by SMI Taiwan of NT$11,506 thousand (US$353 thousand).

On February 3, 2004, O2Micro filed an application for a provisional seizure of NT$15 million against SMI
Taiwan with the Taiwan Hsinchu District Court. The application alleged that SMI Taiwan infringed
O2Micro’s patent, patent registered number 130953, in Taiwan. The Taiwan Hsinchu District Court issued a
provisional seizure order and attached some of SMI Taiwan’s assets. Upon placing a deposit of NT$15
million, the Taiwan Hsinchu District Court has released the enforcement of the provisional seizure order.

On September 24, 2004, O2Micro filed an action against SMI Taiwan with the Taiwan Hsinchu District
Court. The complaint alleges that SMI Taiwan infringed O2Micro’s patent, Taiwan patent registered
number 130953, and O2Micro has requested SMI Taiwan to cease and desist the tortuous act and a
preliminary compensation in the amount of NT$3 million (US$92,000). On February 9, 2007, SMI Taiwan
and O2Micro agreed to withdraw this case, as well as all the above-mentioned claims and application. As a
result of this agreement, the management of SMI believes this case will not adversely affect SMI’s
operations or financial condition.

On May 1, 2005, SMI Taiwan incurred a loss on inventory in the possession of subcontractor, Advanced
Semiconductor Engineering Inc. (hereinafter referred to ASE) due to fire, SMI Taiwan is currently in the
claims process with ASE. for an amount exceeding the book value of loss inventory. After consultation with

F-27

the Company’s outside legal consul, the Company believes it is highly probable for the Company to receive
reimbursement for the lost inventory at full book value, and the Company subsequently recorded
NT$41,226 thousand (US$1.3 million) of inventory loss, offset by NT$41,226 thousand (US$1.3million) of
fire loss reimbursement, resulting in zero impact to the earnings for the period. In connection with the
inventory loss, the Company also recorded NT$8,122 thousand (US$249,000) under operating expenses for
amounts paid to certain customers for delays in shipment caused by the fire.

On December 12, 2005, SMI Taiwan filed an action against ASE with the Taiwan Taoyuan District Court.
SMI Taiwan alleges that ASE destroyed the wafer which SMI Taiwan had consigned to ASE with the OEM
Agreement between SMI and ASE, and that ASE should pay SMI Taiwan a sum of NT$77,218 thousand
(US$2.4 million) for damages. As of April 30, 2007, the Taiwan Taoyuan District Court is presently
conducting the preparatory proceeding.

Our management currently believes that the legal proceedings described above, individually or in the
aggregate, will not have a material adverse effect on our financial position or operating results. The
litigation and other claims noted above, however, are subject to inherent uncertainties and management’s
view of these matters may change in the future.

18 SUBSEQUENT EVENTS

On April 30, 2007, the Company completed its acquisition of Future Communications IC, Inc., (“FCI”) a
leading designer of radio frequency integrated circuits (RF ICs) for mobile television and wireless
communications based in Seoul, South Korea.

The acquisition was accounted for as a purchase transaction. The final purchase price for the transaction was
approximately US$50 million in cash and US$40 million in the Company’s ordinary shares and options to
purchase the Company’s ordinary shares. The Company has agreed to pay FCI shareholders up to an
additional US$12 million in cash under certain circumstances. The first condition is that FCI achieves, for
its fiscal year 2007 ending December 31, 2007, a US$33 million revenue target and a 53% product margin
target. The second condition relates to the performance of the Company’s stock. If both the FCI revenue and
product margin targets are reached, the Company has agreed to pay to FCI shareholders in cash the
difference between US$12 million and 90% of the appreciation of the Company’s ADSs over an agreed
period of time in the stock portion of the consideration received as part of this transaction.

GLOSSARY OF TECHNICAL TERMS

Annex A

An audio interface. Has significant advantages over the most
prevalent power conversion technologies, which are based on Pulse
Width Modulation (PWM). These advantages stem from the
simplicity and versatility of its circuit topology (hardware), combined
with the sophistication of its control methodology (software).

Adjacent Channel Selectivity. ACS is a measurement of a receiver’s
ability to process a desired signal while rejecting a strong signal in an
adjacent frequency channel. ACS is defined as the ratio of the
receiver filter attenuation on the assigned channel frequency to the
receiver filter attenuation on the adjacent channel frequency.

Arsine. A colorless, flammable, highly toxic gas used as a doping
agent for the preparation of semiconductor materials.

Most NAND flash, like all types of mass storage memory, contain
some initial bad blocks within the memory array, which are typically
marked as bad by the manufacturer to indicate that they should not be
used. Because good blocks in a NAND flash can degrade and wear
out, it is important for devices using NAND flash to track not only the
initial, factory-marked bad blocks but also the blocks that go bad
during normal operation and manage this issue with appropriate bad
block management algorithm. A block is the smallest erasable entity
in a NAND flash.

A NAND flash is occasionally affected by corruption of memory at
the binary digit (bit) level, which must be corrected by complex error
correcting algorithms, know as error correction codes (ECC).

The space a device occupies on a motherboard.

Compact Flash. A type of non-volatile memory storage media
commonly used in portable devices such as personal computers,
digital cameras, video camcorders, and audio players.

25,000,000 Ordinary Shares, inclusive of the number of Former Plan Shares (as defined below).

(b) Reversion of Shares and Availability of Shares to the Share Reserve. If any Stock Award granted

the Ordinary Shares at the date of grant and the Option is not exercisable after the expiration of five (5) years
from the date of grant.

(c) Consultants and Eligible Trusts. A Consultant or Eligible Trust shall not be eligible for the grant of a
Stock Award if, at the time of grant, a Form S-8 Registration Statement under the Securities Act (“Form S-8”) is
not available to register either the offer or the sale of the Company’s securities to such Consultant or Eligible
Trust because of the nature of the services that the Consultant is providing to the Company, or because the
Consultant or Eligible Trust is not a natural person, or as otherwise provided by the rules governing the use of
Form S-8, unless the Company determines both (i) that such grant (A) shall be registered in another manner
under the Securities Act (e.g., on a Form F-3 Registration Statement) or (B) does not require registration under
the Securities Act in order to comply with the requirements of the Securities Act, if applicable, and (ii) that such
grant complies with the securities laws of all other relevant jurisdictions. Form S-8 generally is available to
consultants and advisors only if (i) they are natural persons, (ii) they provide bona fide services to the issuer, its
parents, its majority-owned subsidiaries or majority-owned subsidiaries of the issuer's parent, and (iii) the
services are not in connection with the offer or sale of securities in a capital-raising transaction, and do not
directly or indirectly promote or maintain a market for the issuer’s securities.

with the laws in other countries in which the Company and its subsidiaries operate or have Employees, Directors
or Consultants, the Board, in its sole discretion, shall have the power and authority to: (i) determine which
subsidiaries shall be covered by the Plan; (ii) determine which Employees, Directors or Consultants outside the

granted to Employees, Directors or Consultants outside the United States to comply with applicable foreign laws;
(iv) establish subplans and modify exercise procedures and other terms and procedures, to the extent such actions
may be necessary or advisable (any such subplans and/or modifications shall be attached to this subplan as
appendices); provided, however, that no such subplans and/or modifications shall increase the number of shares
reserved for the Plan as set forth in Section 4 of the Plan; and (v) take any action, before or after a Stock Award
is made, that it deems advisable to obtain approval or comply with any applicable foreign laws.

6. OPTION PROVISIONS.

Each Option shall be in such form and shall contain such terms and conditions as the Board shall deem
appropriate. All Options shall be separately designated Incentive Stock Options or Nonstatutory Stock Options at
the time of grant, and, if certificates are issued, a separate certificate or certificates will be issued for Ordinary
Shares purchased on exercise of each type of Option. The provisions of separate Options need not be identical,
but each Option shall include (through incorporation of provisions hereof by reference in the Option Agreement
or otherwise) the substance of each of the following provisions:

(a) Term. Subject to the provisions of Section 5(b) regarding Ten Percent Shareholders, no Option shall be

exercisable after the expiration of ten (10) years from the date it was granted.

(b) Exercise Price of an Incentive Stock Option. Subject to the provisions of Section 5(b) regarding Ten

Percent Shareholders, the exercise price of each Incentive Stock Option shall be not less than one hundred
percent (100%) of the Fair Market Value of the Ordinary Shares subject to the Option on the date the Option is
granted. Notwithstanding the foregoing, an Incentive Stock Option may be granted with an exercise price lower
than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution
for another option in a manner satisfying the provisions of Section 424(a) of the Code.

(c) Exercise Price of a Nonstatutory Stock Option. The exercise price of Nonstatutory Stock Options
shall be determined by the Board. However, the exercise price of each Nonstatutory Stock Option that is intended
to qualify as performance-based compensation within the meaning of the Treasury Regulations promulgated
under Section 162(m) of the Code shall be not less than one hundred percent (100%) of the Fair Market Value of
the Ordinary Shares subject to the Option on the date the Option is granted.

(d) Consideration. The purchase price of Ordinary Shares acquired pursuant to an Option shall be paid, to
the extent permitted by applicable statutes and regulations, either (i) in cash at the time the Option is exercised,
or (ii) at the discretion of the Board at the time of the grant of the Option (or subsequently in the case of a
Nonstatutory Stock Option) (A) by delivery to the Company of other Ordinary Shares, (B) according to a
deferred payment or other similar arrangement with the Optionholder, (C) pursuant to a cashless exercise
program implemented by the Company in connection with the Plan, or (D) in any other form of legal
consideration that may be acceptable to the Board. Unless otherwise specifically provided in the Option
Agreement, the purchase price of Ordinary Shares acquired pursuant to an Option that is paid by delivery to the
Company of other Ordinary Shares acquired, directly or indirectly from the Company, shall be paid only by
shares of the Ordinary Shares of the Company that have been held for more than six (6) months (or such longer
or shorter period of time required to avoid a charge to earnings for financial accounting purposes).

In the case of any deferred payment arrangement, interest shall be compounded at least annually and shall

be charged at the minimum rate of interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest under the deferred payment
arrangement.

(e) Transferability of an Incentive Stock Option. An Incentive Stock Option shall not be transferable

except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the
Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering
written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of
the death of the Optionholder, shall thereafter be entitled to exercise the Option.

(f) Transferability of a Nonstatutory Stock Option. A Nonstatutory Stock Option shall be transferable

only to the extent provided in the Option Agreement (subject to applicable securities laws). Notwithstanding the
foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the
Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to
exercise the Option.

(g) Vesting Generally. The total number of Ordinary Shares subject to an Option may, but need not, vest
and therefore become exercisable in periodic installments that may, but need not, be equal. The Option may be
subject to such other terms and conditions on the time or times when it may be exercised (which may be based on
performance or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options
may vary. The provisions of this Section 6(g) are subject to any Option provisions governing the minimum
number of Ordinary Shares as to which an Option may be exercised.

(h) Termination of Continuous Service. In the event an Optionholder’s Continuous Service terminates
(other than upon the Optionholder’s death or Disability), the Optionholder may exercise his or her Option (to the
extent that the Optionholder was entitled to exercise such Option as of the date of termination) but only within
such period of time ending on the earlier of (i) the date three (3) months following the termination of the
Optionholder’s Continuous Service (or, except with respect to Incentive Stock Options, such longer or shorter
period specified in the Option Agreement), or (ii) the expiration of the term of the Option as set forth in the
Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time
specified in the Option Agreement, the Option shall terminate.

(i) Extension of Termination Date. Except with respect to Incentive Stock Options, an Optionholder’s

Option Agreement may also provide that if the exercise of the Option following the termination of the
Optionholder’s Continuous Service (other than upon the Optionholder’s death or Disability) would be prohibited
at any time solely because the issuance of Ordinary Shares would violate the registration requirements under the
Securities Act, then the Option shall terminate on the earlier of (i) the expiration of the term of the Option set
forth in Section 6(a), or (ii) the expiration of a period of three (3) months after the termination of the
Optionholder’s Continuous Service during which the exercise of the Option would not be in violation of such
registration requirements.

(j) Disability of Optionholder. In the event that an Optionholder’s Continuous Service terminates as a

result of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the extent that the
Optionholder was entitled to exercise such Option as of the date of termination), but only within such period of
time ending on the earlier of (i) the date twelve (12) months following such termination (or, except with respect
to Incentive Stock Options, such longer or shorter period specified in the Option Agreement) or (ii) the expiration
of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not
exercise his or her Option within the time specified herein, the Option shall terminate.

(k) Death of Optionholder. In the event (i) an Optionholder’s Continuous Service terminates as a result of

the Optionholder’s death or (ii) the Optionholder dies within the period (if any) specified in the Option Agreement
after the termination of the Optionholder’s Continuous Service for a reason other than death, then the Option may
be exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the
Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a
person designated to exercise the option upon the Optionholder’s death pursuant to Section 6(e) or 6(f), but only
within the period ending on the earlier of (A) the date eighteen (18) months following the date of death (or, except
with respect to Incentive Stock Options, such longer or shorter period specified in the Option Agreement) or
(B) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not
exercised within the time specified herein, the Option shall terminate.

(l) Early Exercise. The Option may, but need not, include a provision whereby the Optionholder may elect
at any time before the Optionholder’s Continuous Service terminates to exercise the Option as to any part or all
of the Ordinary Shares subject to the Option prior to the full vesting of the Option. The early purchase of any
unvested Ordinary Shares will be pursuant to an early exercise provision in the Option Agreement which may

provide for a repurchase option in favor of the Company and other restrictions the Board determines to be
appropriate. Any repurchase option so provided for will be subject to the repurchase provisions set forth in
Section 11(h) herein.

(m) Substitution of Stock Appreciation Rights for Options. If the Company is required to or elects to
expense the cost of Options pursuant to FAS 123 (or a successor or other standard), the Board shall have the sole
discretion to substitute without receiving Participants’ permission, Stock Appreciation Rights paid only in stock
for outstanding Options; provided, the terms of the substituted Stock Appreciation Rights are substantially the
same as the terms of the Options, the number of shares underlying the number of Stock Appreciation Rights
equals the number of shares underlying the Options and the difference between the Fair Market Value of the
underlying Ordinary Shares and the grant price of the Stock Appreciation Rights is equivalent to the difference
between the Fair Market Value of the underlying Ordinary Shares and the exercise price of the Options.

(n) Re-Load Options.

(i) Without in any way limiting the authority of the Board to make or not to make grants of Options

hereunder, the Board shall have the authority (but not an obligation) to include as part of any Option
Agreement a provision entitling the Optionholder to a further Option (a “Re-Load Option”) in the event the
Optionholder exercises the Option evidenced by the Option Agreement, in whole or in part, by surrendering
other Ordinary Shares in accordance with this Plan and the terms and conditions of the Option Agreement.
Unless otherwise specifically provided in the Option Agreement, the Optionholder shall not surrender
Ordinary Shares acquired, directly or indirectly from the Company, unless such shares have been held for
more than six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for
financial accounting purposes).

(ii) Any such Re-Load Option shall (i) provide for a number of Ordinary Shares equal to the number of

Ordinary Shares surrendered as part or all of the exercise price of such Option, (ii) have an expiration date
which is the same as the expiration date of the Option the exercise of which gave rise to such Re-Load
Option, and (iii) have an exercise price which is equal to one hundred percent (100%) of the Fair Market
Value of the Ordinary Shares subject to the Re-Load Option on the date of exercise of the original Option.
Notwithstanding the foregoing, a Re-Load Option shall be subject to the same exercise price and term
provisions heretofore described for Options under the Plan.

Any such Re-Load Option may be an Incentive Stock Option or a Nonstatutory Stock Option, as the Board

may designate at the time of the grant of the original Option; provided, however, that the designation of any
Re-Load Option as an Incentive Stock Option shall be subject to the one hundred thousand dollar ($100,000)
annual limitation on the exercisability of Incentive Stock Options described in Section 11(d) of the Plan and in
Section 422(d) of the Code. There shall be no Re-Load Options on a Re-Load Option. Any such Re-Load Option
shall be subject to the availability of sufficient Ordinary Shares under Section 4(a) and shall be subject to such
other terms and conditions as the Board may determine that are not inconsistent with the express provisions of
the Plan regarding the terms of Options.

PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS.

(a) Stock Bonus Awards. Grants of stock bonus awards shall be pursuant to a Stock Award Agreement,
which shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The
terms and conditions of each grant of a stock bonus award shall include (through incorporation of provisions
hereof by reference in the Stock Award Agreement or otherwise) the substance of each of the following
provisions:

(i) Consideration. A stock bonus may be awarded in consideration for past services rendered to the

Company or an Affiliate for its benefit.

(ii) Vesting; Right of Repurchase. Ordinary Shares awarded under the Stock Award Agreement may,
but need not, be subject to a share repurchase option in favor of the Company in accordance with a vesting
schedule to be determined by the Board. Such repurchase option is subject to the repurchase provisions set
forth in Section 11(h).

(iii) Termination of Participant’s Continuous Service. In the event a Participant’s Continuous
Service terminates, the Company may reacquire any or all of the Ordinary Shares held by the Participant
which have not vested as of the date of termination under the terms of the Stock Award Agreement. In such
event, the Company shall not reaquire the Ordinary Shares until after the Repurchase Blackout Period.

(iv) Transferability. Rights to acquire Ordinary Shares under the Stock Award Agreement shall be

transferable by the Participant only upon such terms and conditions as are set forth in the Stock Award
Agreement, as the Board shall determine in its discretion, so long as Ordinary Shares awarded under the
Stock Award Agreement remains subject to the terms of the Stock Award Agreement.

(b) Restricted Stock and Restricted Stock Units.

(i) Designation. Restricted Stock or Restricted Stock Units may be granted under the Plan. Restricted

Stock or Restricted Stock Units may include a dividend equivalent right, as permitted by Section 12(a).
After the Board determines that it will offer Restricted Stock or Restricted Stock Units, it will advise the
Participant in writing or electronically, by means of a Stock Award Agreement, of the terms, conditions and
restrictions, including vesting, if any, related to the offer, including the number of Ordinary Shares that the
Participant shall be entitled to receive or purchase, the price to be paid, if any, and, if applicable, the time
within which the Participant must accept the offer. The offer shall be accepted by execution of a Stock
Award Agreement or as otherwise directed by the Board. The term of each award of Restricted Stock or
Restricted Stock Units shall be at the discretion of the Board.

(ii) Restrictions. Subject to Section 8(b)(iii), the Board may impose such conditions or restrictions on

the Restricted Stock or Restricted Stock Units granted pursuant to the Plan as it may determine advisable,
including the achievement of specific performance goals, time based restrictions on vesting, or others. If the
Board established performance goals, the Board shall determine whether a Participant has satisfied the
performance goals.

(iii) Performance Criteria. Restricted Stock and Restricted Stock Units granted pursuant to the Plan
that are intended to qualify as “performance based compensation” under Section 162(m) of the Code shall
be subject to the attainment of performance goals relating to the Performance Criteria selected by the Board
and specified at the time such Restricted Stock and Restricted Stock Units are granted. For purposes of this
Plan, “Performance Criteria” means any one criterion or multiple criteria for measuring performance
selected by the Board in its sole discretion, the measurement of which may be based upon Company,
Subsidiary or business unit performance, or the individual performance of the Participant, either absolute or
by relative comparison to other companies, other Participants or any other external measure of the selected
criteria. Performance Criteria may include, without limitation, one or more of the following (as selected by
the Board): (1) cash flow; (2) earnings per share; (3) earnings before interest, taxes, and amortization;
(4) return on equity; (5) total shareholder return; (6) share price performance; (7) return on capital;
(8) return on assets or net assets; (9) revenue; (10) revenue growth; (11) earnings growth; (12) operating
income; (13) operating profit; (14) profit margin; (15) return on operating revenue; (16) return on invested
capital; (17) operating efficiency; or (18) productivity.

(iv) Transferability. Restricted Stock and Restricted Stock Units shall be transferable by the
Participant only upon such terms and conditions as are set forth in the Stock Award Agreement, as the
Board shall determine in its discretion.

(v) Vesting. Unless the Board determines otherwise, the Stock Award Agreement shall provide for the

forfeiture of the non-vested Ordinary Shares underlying Restricted Stock or the termination of unvested
Restricted Stock Units upon termination of a Participant’s Continuous Service. To the extent that the
Participant purchased the Ordinary Shares granted under any such Restricted Stock award and any such
Ordinary Shares remain non-vested at the time of termination of a Participant’s Continuous Service, the
termination of Participant’s Continuous Service shall cause an immediate sale of such non-vested Ordinary
Shares to the Company at the original price per share of Ordinary Shares paid by the Participant.

(c) Stock Appreciation Rights. Grants of Stock Appreciation Rights shall be pursuant to a Stock Award
Agreement, which shall be in such form and shall contain such terms and conditions, as the Board shall deem

appropriate. The Board may grant Stock Appreciation Rights in connection with all or any part of an Option
(“Tandem Stock Appreciation Rights”) to a Participant or in a stand-alone grant (“Stand-Alone Stock
Appreciation Rights”). The terms and conditions of a Stock Appreciation Right shall include (through
incorporation of the provisions hereof by reference in the Stock Award Agreement or otherwise) the substance of
each of the following provisions:

(i) Calculation of Appreciation. Each Stock Appreciation Right will be denominated in Ordinary
Shares equivalents. The appreciation distribution payable on the exercise of a Stock Appreciation Right will
be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of the
exercise of the Stock Appreciation Right) of a number of Ordinary Shares equal to the number of share of
Ordinary Shares equivalents in which the Participant is vested under such Stock Appreciation Right and
with respect to which the Participant is exercising the Stock Appreciation Right on such date, over (B) an
amount that will be determined by the Board at the time of grant of the Stock Appreciation Right (which
amount, in the case of Stock Appreciation Rights intended to qualify as performance-based compensation
within the meaning of the Treasury Regulations under Section 162(m) of the Code, shall be not less than the
Fair Market Value of such Ordinary Shares at the time of grant of the Ordinary Shares equivalents).

(ii) Vesting. At the time of the grant of a Stock Appreciation Right, the Board may impose such

restrictions or conditions to the vesting of such Stock Appreciation Right as it deems appropriate.

(iii) Exercise. To exercise any outstanding Stock Appreciation Right, the Participant must provide
written notice of exercise to the Company in compliance with the provisions of the Stock Award Agreement
evidencing such Stock Appreciation Right.

(iv) Payment. The appreciation distribution in respect of a Stock Appreciation Right may be paid in

Ordinary Shares, in cash, or any combination of the two, as the Board deems appropriate.

(v) Termination of Continuous Service. If a Participant’s Continuous Service terminates for any
reason, any unvested Stock Appreciation Rights shall be forfeited and any vested Stock Appreciation Rights
shall be automatically redeemed.

(vi) Transferability. Stock Appreciation Rights shall be transferable by the Participant only upon such

terms and conditions as are set forth in the Stock Award Agreement, as the Board shall determine in its
discretion.

(vii) Tandem Stock Appreciation Rights. A Tandem Stock Appreciation Right shall be exercisable

only to the extent that the related Option is exercisable and a Tandem Stock Appreciation Right shall expire
no later than the date on which the related Option expires.

8. COVENANTS OF THE COMPANY.

(a) Availability of Shares. During the terms of the Stock Awards, the Company shall keep available at all

times the number of Ordinary Shares required to satisfy such Stock Awards.

(b) Securities Law Compliance. The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue
and sell Ordinary Shares upon exercise of the Stock Awards; provided, however, that this undertaking shall not
require the Company to register under the Securities Act the Plan, any Stock Award or any Ordinary Shares
issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company is unable to obtain
from any such regulatory commission or agency the authority which counsel for the Company deems necessary
for the lawful issuance and sale of Ordinary Shares under the Plan, the Company shall be relieved from any
liability for failure to issue and sell Ordinary Shares upon exercise of such Stock Awards unless and until such
authority is obtained.

9. USE OF PROCEEDS FROM STOCK.

Proceeds from the sale of Ordinary Shares pursuant to Stock Awards shall constitute general funds of the

Company.

10. EFFECTIVE DATE OF PLAN.

The Plan shall become effective as determined by the Board, but no Stock Award shall be exercised (or, in

the case of a stock bonus, shall be granted) unless and until the Plan has been approved by the shareholders of the
Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the
Board.

11. MISCELLANEOUS.

(a) Acceleration of Exercisability and Vesting. The Board shall have the power to accelerate the time at
which a Stock Award may first be exercised or the time during which a Stock Award or any part thereof will vest
in accordance with the Plan, notwithstanding the provisions in the Stock Award stating the time at which it may
first be exercised or the time during which it will vest.

(b) Shareholder Rights. No Participant shall be deemed to be the holder of, or to have any of the rights of a

holder with respect to, any Ordinary Shares subject to such Stock Award unless and until such Participant has
satisfied all requirements for exercise of the Stock Award pursuant to its terms.

(c) No Employment or other Service Rights. Nothing in the Plan or any instrument executed or Stock
Award granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company or
an Affiliate in the capacity in effect at the time the Stock Award was granted or shall affect the right of the
Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or
without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the
Company or an Affiliate, or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate,
and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is
incorporated, as the case may be.

(d) Incentive Stock Option $100,000 Limitation. To the extent that the aggregate Fair Market Value

(determined at the time of grant) of Ordinary Shares with respect to which Incentive Stock Options are
exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and
its Affiliates) exceeds one hundred thousand dollars ($100,000), the Options or portions thereof which exceed
such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options.

(e) Maximum Award Amounts. In no event shall a Participant receive a Stock Award or Stock Awards

during any one (1) calendar year covering in the aggregate more than 2,000,000 Ordinary Shares.

(f) Investment Assurances. The Company may require a Participant, as a condition of exercising or
acquiring Ordinary Shares under any Stock Award (i) to give written assurances satisfactory to the Company as
to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser
representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and
business matters and that he or she is capable of evaluating, alone or together with the purchaser representative,
the merits and risks of exercising the Stock Award, and (ii) to give written assurances satisfactory to the
Company stating that the Participant is acquiring Ordinary Shares subject to the Stock Award for the
Participant’s own account and not with any present intention of selling or otherwise distributing the Ordinary
Shares. The foregoing requirements, and any assurances given pursuant to such requirements, shall be
inoperative if (1) the issuance of the Ordinary Shares upon the exercise or acquisition of Ordinary Shares under
the Stock Award has been registered under a then currently effective registration statement under the Securities
Act, or (2) as to any particular requirement, a determination is made by counsel for the Company that such
requirement need not be met in the circumstances under the then applicable securities laws. The Company may,
upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel
deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to,
legends restricting the transfer of the Ordinary Shares.

(g) Withholding Obligations. To the extent provided by the terms of a Stock Award Agreement, the

Participant may satisfy any federal, state or local tax withholding obligation relating to the exercise or acquisition of
Ordinary Shares under a Stock Award by any of the following means (in addition to the Company’s right to

withhold from any compensation paid to the Participant by the Company) or by a combination of such means:
(i) tendering a cash payment, (ii) authorizing the Company to withhold Ordinary Shares from the Ordinary Shares
otherwise issuable to the Participant as a result of the exercise or acquisition of Ordinary Shares under the Stock
Award, provided, however, that no Ordinary Shares are withheld with a value exceeding the minimum amount of
tax required to be withheld by law, or (iii) delivering to the Company owned and unencumbered Ordinary Shares.

(h) Repurchase Provisions. The Company shall exercise any repurchase option specified in the Stock

Award by giving the holder of the Stock Award written notice of intent to exercise the repurchase option.
Payment may be cash or cancellation of purchase money indebtedness for the Ordinary Shares. The terms of any
repurchase option shall be specified in the Stock Award and may be either at Fair Market Value at the time of
repurchase or at not less than the original purchase price.

(i) Golden Parachute Taxes. In the event that any amounts paid or deemed paid to a Participant under the
Plan are deemed to constitute “excess parachute payments” as defined in Section 280G of the Code (taking into
account any other payments made under the Plan and any other compensation paid or deemed paid to a
Participant), or if any Participant is deemed to receive an “excess parachute payment” by reason of his or her
vesting of Options pursuant to Section 12(c) herein, the amount of such payments or deemed payments shall be
reduced (or, alternatively the provisions of Section 12(c) shall not act to vest options to such Participant), so that
no such payments or deemed payments shall constitute excess parachute payments. provided, however, that if a
Participant is subject to a separate agreement with the Company or an Affiliate which specifically provides that
payments attributable to one or more forms of employee stock incentives or to payments made in lieu of
employee stock incentives will not reduce any other payments under such agreement, even if it would constitute
an excess parachute payment, or provides that the Participant will have the discretion to determine which
payments will be reduced in order to avoid an excess parachute payment, then the limitations of this Section 11(l)
will, to that extent, not apply. The determination of whether a payment or deemed payment constitutes an excess
parachute payment shall be in the sole discretion of the Board.

(j) Right to American Depository Shares (“ADSs”). The Company may arrange, in its sole discretion, for
any one or more Participants to receive ADSs rather than Ordinary Shares upon the exercise of Stock Awards, in
which case, all references to “Ordinary Shares” in this Plan or any other document related to the Plan shall be
deemed to reference the appropriate number of ADSs per Ordinary Share, as the context may require with respect
to such Stock Awards.

(k) Plan Unfunded. The Plan shall be unfunded. Except for the Board’s reservation of a sufficient number
of authorized shares to the extent required by law to meet the requirements of the Plan, the Company shall not be
required to establish any special or separate fund or to make any other segregation of assets to assure payment of
any Stock Award under the Plan.

12. Adjustments upon Changes in Stock.

(a) Capitalization Adjustments. In the event that any dividend or other distribution (whether in the form of
cash, shares of the Ordinary Shares, other securities, or other property), recapitalization, stock split, reverse stock
split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, exchange of Ordinary Shares
or other securities of the Company, or other change in the corporate structure of the Company affecting the Ordinary
Shares occurs, the Board, in order to prevent diminution or enlargement of the benefits or potential benefits intended
to be made available under the Plan, may, in its sole discretion, adjust the number and class of Ordinary Shares that
may be delivered under the Plan and/or the number, class, and price of Ordinary Shares covered by each outstanding
Stock Award. In lieu of the payment of a dividend the Board in its discretion may provide holders of Restricted Stock
or Restricted Stock Units a dividend equivalent right, in the form of additional Ordinary Shares or units, with respect
to the unvested Ordinary Shares or unvested units the Participant shall be entitled to receive or purchase.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the
Board will notify each Participant as soon as practicable prior to the effective date of such proposed transaction.
To the extent it has not been previously exercised, a Stock Award will terminate immediately prior to the
consummation of such proposed action.

(c) Change in Control. In the event of Change in Control, then, to the extent permitted by applicable law:

(1) any surviving corporation may assume any Stock Awards outstanding under the Plan or may substitute
similar stock awards (including an award to acquire the same consideration paid to the shareholders in the
transaction described in this Section 12(c)) for those outstanding under the Plan, or (2) in the event any surviving
corporation does not assume or continue such Stock Awards, or substitute similar stock awards for those
outstanding under the Plan in accordance with the preceding clause, then the time during which such Stock
Awards may be exercised automatically will be accelerated and become fully vested and exercisable immediately
prior to the consummation of such transaction, and the Stock Awards shall automatically terminate upon
consummation of such transaction if not exercised prior to such event.

(d) No Limitations. The grant of Stock Awards will in no way affect the Company's right to adjust,
reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve,
liquidate or sell or transfer all or any part of its business or assets.

13. AMENDMENT OF THE PLAN AND STOCK AWARDS.

(a) Amendment of Plan. The Board at any time, and from time to time, may amend the Plan. However,

except as provided in Section 12 relating to adjustments upon changes in Ordinary Shares, no amendment shall
be effective unless approved by the shareholders of the Company to the extent shareholder approval is necessary
to satisfy the applicable requirements of Section 422 or 162(m) of the Code and the Treasury Regulations
thereunder, Rule 16b-3 under the Exchange Act or any Nasdaq or securities exchange listing requirements. For
purposes of clarity, any increase in the number of shares reserved for issuance hereunder in accordance with the
provisions of Section 4(a) hereof shall not be deemed to be an amendment to the Plan.

(b) Contemplated Amendments. It is expressly contemplated that the Board may amend the Plan in any

respect the Board deems necessary or advisable to provide eligible Employees with the maximum benefits
provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating
to Incentive Stock Options and/or to bring the Plan and/or Incentive Stock Options granted under it into
compliance therewith.

(c) No Impairment of Rights. Rights under any Stock Award granted before amendment of the Plan shall

not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the Participant and
(ii) the Participant consents in writing.

(d) Amendment of Stock Awards. The Board at any time, and from time to time, may amend the terms of
any one or more Stock Awards; provided, however, that the rights under any Stock Award shall not be impaired
by any such amendment unless (i) the Company requests the consent of the Participant and (ii) the Participant
consents in writing.

14. TERMINATION OR SUSPENSION OF THE PLAN.

(a) Plan Term. The Board may suspend or terminate the Plan at any time. Unless sooner terminated, the
Plan shall terminate on the day before the tenth (10th) anniversary of the date the Plan is adopted by the Board or
approved by the shareholders of the Company, whichever is later. No Stock Awards may be granted under the
Plan while the Plan is suspended or after it is terminated.

(b) No Impairment of Rights. Suspension or termination of the Plan shall not impair rights and obligations

under any Stock Award granted while the Plan is in effect except with the written consent of the Participant.

15. CHOICE OF LAW.

The law of California shall govern all questions concerning the construction, validity and interpretation of

this Plan, without regard to such state’s conflict of laws rules

(b) As soon as practicable, but in no event more than sixty (60) days, following the Closing, Purchaser
shall prepare, or cause to be prepared, and deliver to the Sellers’ Representative the “Final Closing Balance
Sheet” of the Company as of the Closing, which shall be prepared in accordance with the Company’s
current accounting methods, policies, practices and procedures under the Adjusted Korean GAAP and in the
same manner, with consistent classification and estimation methodology, as the Projected Closing Balance
Sheet was prepared. Upon completion of the Final Closing Balance Sheet, Purchaser shall derive the
Closing Net Asset Value from the Final Closing Balance Sheet, and deliver a statement of such calculation
of the Final Adjustment Amount the Closing Net Asset Statement to the Sellers’ Representative. The “Final
Adjustment Amount” shall be the amount equal to Closing Net Asset Value minus the Net Assets set forth
on the Company’s balance sheet as of December 31, 2006.

(c) Sellers shall complete its review of the Final Closing Balance Sheet and Purchaser’s calculation of
the Closing Net Asset Value within thirty (30) days after delivery thereof to the Sellers’ Representative by
Purchaser. If the Sellers’ Representative disputes all, any part or basis of the Closing Net Asset Statement,
the Sellers’ Representative shall, on or before the last day of such thirty (30)-day period, so inform
Purchaser in writing (the “Sellers’ Objection”), setting forth a description of the basis of Sellers’
determination and proposed adjustments to the Closing Net Asset Statement and the corresponding
adjustments to the Closing Net Asset Value that the Sellers’ Representative believes should be made. If no
Sellers’ Objection is received by Purchaser on or before the last day of such thirty (30)day period, then the
Closing Net Asset Value set forth on the Closing Net Asset Statement delivered by Purchaser shall be final,
conclusive and binding upon the Parties. Purchaser shall have thirty (30) days from its receipt of the Sellers’
Objection to review and respond to the Sellers’ Objection.

(d) If Purchaser and the Sellers’ Representative are unable to resolve all of their disagreements with

respect to the proposed adjustments set forth in the Sellers’ Objection within forty-five (45) days following
Purchaser’s receipt of the Sellers’ Objection, they shall refer any remaining disagreements to the CPA Firm,
which, acting as experts and not as arbitrators, shall determine, on the basis set forth in and in accordance
with Section 2.3(a), and only with respect to the remaining differences so submitted, whether and to what
extent, if any, the Closing Net Asset Statement and the Closing Net Asset Value require adjustment.
Purchaser and the Sellers’ Representative shall instruct the CPA Firm to deliver its written determination to
Purchaser and the Sellers’ Representative no later than thirty (30) days after the remaining differences
underlying the Sellers’ Objection are referred to the CPA Firm. The CPA Firm’s determination shall be
final, conclusive and binding upon Purchaser and Sellers. The fees and disbursements of the CPA Firm shall
be borne equally by Purchaser and Sellers. Purchaser and Sellers shall make readily available to the CPA
Firm all relevant books and records and any work papers (including those of the parties’ respective
accountants, to the extent permitted by such accountants) relating to the Closing Net Asset Statement and
the Sellers’ Objection and all other items reasonably requested by the CPA Firm in connection therewith.

(e) Sellers shall have full access to all information used by Purchaser in preparing the Closing Net
Asset Statement, including the work papers of its accountants (to the extent permitted by such accountants).

(f) The Purchase Price shall be further adjusted by the Post-Closing Adjustment Amount. If the Post-

Closing Adjustment Amount is a negative number in excess of Three Hundred Thousand U.S. Dollars
(US$300,000), then the Purchase Price shall be decreased by the Post-Closing Adjustment Amount to the

10

extent such amount is in excess of Three Hundred Thousand U.S. Dollars (US$300,000) and Purchaser shall
withdraw in cash after the final determination thereof this amount from the Escrow in accordance with the
Escrow Agreement, without regard to any Threshold set forth in Section 13 hereof. If the Post-Closing
Adjustment Amount is a positive number, then the Purchase Price shall be increased by the Post-Closing
Adjustment Amount and Purchaser and Parent shall promptly (and in any event within one calendar week)
after the final determination thereof pay to Sellers the Post-Closing Adjustment Amount in cash, without
regard to any Threshold set forth in Section 13 hereof.

(g) Notwithstanding anything herein to the contrary, if the amount that would otherwise constitute the

Post-Closing Adjustment Amount (as such Post-Closing Adjustment Amount, if a negative number, is
reduced by Three Hundred Thousand U.S. Dollars (US$300,000) pursuant to Section 2.3(f)) is equal to or
less than One Hundred Thousand U.S. Dollars (US$100,000), no adjustment to the Purchase Price or the
Cash Consideration shall be made and no Post-Closing Adjustment Amount shall be payable to Sellers or
Purchaser/Parent, as the case may be.

2.4 Earn-Out.

(a) In addition to the Purchase Price, if the Company meets or exceeds (i) the Revenue Target and
(ii) the Product Margin Target, Purchaser shall pay in cash to Sellers, on a pro-rata basis, the Earn-Out
Amount less the product of the Stock Consideration and the ADS Appreciation Ratio (the “Earn-Out”)
exclusive of any Tax, fees or other expenses of any kind; provided that the exchange rate shall be fixed at
the Exchange Rate for the calculation of the Earn-Out. The Earn-Out shall not exceed the Earn-Out Amount.

(b) Within ten (10) business days after the announcement date of Parent’s fourth quarter fiscal year

2007, Purchaser shall prepare, or cause to be prepared, and deliver to the Sellers’ Representative (i) a
statement setting forth the Product Revenues for the calendar year 2007, each component used in the
calculation thereof, the ADS Appreciation Ratio and the amount of the Earn-Out determined in accordance
with Section 2.4(a) (the “Earn-Out Statement”), which shall be prepared in accordance with the Adjusted
Korean GAAP, at Purchaser’s cost and expense, and (ii) such documentation, if any, as may be reasonably
necessary to enable the Sellers’ Representative to determine such amount. Concurrently with the delivery of
the Earn-Out Statement, Purchaser shall deposit into a nominated account as established by the Sellers’
Representative for payment to Sellers, on a per share basis, the amount of the Earn-Out, if any, specified in
the Earn-Out Statement.

(c) After receipt from Purchaser of the Earn-Out Statement and, if applicable, the Earn-Out, Sellers
shall have the right, at its cost and expense, and upon not less than seven (7) days’ prior written notice to
Purchaser, to (i) meet with Purchaser and the Company Accounting Firm to discuss Purchaser’s calculation
of the amount of the Product Revenues, the ADS Appreciation Ratio and the Earn-Out as set forth in the
Earn-Out Statement and (ii) have reasonable access during normal business hours to inspect the books and
records of the Company and working papers (including those prepared by advisors and other third parties, to
the extent permitted thereby) relating to such calculation. If the Sellers’ Representative fails to challenge
Purchaser’s determination of the Product Revenues, the ADS Appreciation Ratio and the amount of the
Earn-Out by the delivery of a written notice to Purchaser (the “Earn-Out Dispute Notice”) within sixty
(60) days after receipt by the Sellers’ Representative of the Earn-Out Statement, such determination by
Purchaser shall be final, conclusive and binding for all purposes of this Agreement.

(d) In the event that Sellers disputes Purchaser’s determination of the amount of the Product Revenues,

the ADS Appreciation Ratio and/or the amount of the Earn-Out, the Sellers’ Representative shall so notify
Purchaser by delivering a Earn-Out Dispute Notice to Purchaser within the period set forth in Section 2.4(c)
(the amount of any disputed Contingent Payment being referred to herein as the “Disputed Contingent
Payment”). In the event of such a dispute, Sellers and Purchaser shall first use diligent, good faith efforts to
resolve such dispute between them. If they are unable to resolve the dispute within thirty (30) days after the

11

delivery of the Earn-Out Dispute Notice, then the dispute shall be submitted to the CPA Firm for
determination in accordance with the following provisions:

(i) Purchaser and the Sellers’ Representative shall submit to the CPA Firm, within ten (10) days

objections raised by Sellers with respect to the calculation of the amount of the Earn-Out (the
“Unresolved Objections”). Each of Purchaser and the Sellers’ Representative shall submit to the CPA
Firm (with a copy delivered to the other Party on the same day), within thirty (30) days after the date of
the engagement of the CPA Firm, a memorandum (which may include supporting exhibits) setting
forth their respective positions on the Unresolved Objections. Each of Purchaser and the Sellers’
Representative may (but shall not be required to) submit to the CPA Firm (with a copy delivered to the
other Party on the same day), within sixty (60) days after the date of the engagement of the CPA Firm,
a memorandum responding to the initial memorandum submitted to the CPA Firm by the other Party.
Unless requested by the CPA Firm in writing, neither Purchaser nor the Sellers’ Representative may
present any additional information or arguments to the CPA Firm, either orally or in writing; provided,
however, that each party shall have the right to respond to the CPA Firm’s requests directed to the other
Party.

(ii) The CPA Firm shall prepare and distribute to the Parties a writing setting forth the CPA Firm’s

determination of the Unresolved Objections, the CPA Firm’s reasons therefor and the amount of the
Earn-Out calculated pursuant thereto; provided, however, that the CPA Firm shall not change nor
deviate from the calculation of any item not specifically challenged in the Unresolved Objections. Any
decision rendered by the CPA Firm shall be final, conclusive and binding upon the Parties, and
judgment thereon may be entered and enforced in any court of competent jurisdiction.

(iii) The fees and expenses of the CPA Firm in connection with the resolution of disputes pursuant

to this paragraph (d) shall be shared equally by Purchaser and Sellers; provided, however, that if the
CPA Firm determines that one Party has adopted a position or positions that is or are frivolous or
clearly without merit, the CPA Firm may, in its discretion, assign a greater portion of such fees and
expenses to such Party.

(e) From the Closing Date through December 31, 2007, except as otherwise contemplated by this

revenues therefrom attributable to the Customer Offerings shall be included in the calculation of the Product
Profits, the Product Revenues and the Product Margin.

Ordinary Shares issued to the Ordinary Share Recipients will contain customary legends restricting the transfer
of the Ordinary Shares and Parent will notify its transfer agent of such restrictions; which legends will be
removed from an Ordinary Share certificate at the request of the relevant Ordinary Share Recipient or another
holder thereof in connection with the proposed transfer thereof, including, in the case of the securities Laws
legend, receipt by Parent of an opinion of counsel, in form and substance satisfactory to Parent, or a no-action
letter from the SEC addressed to Parent, to the effect that registration under the Securities Act is unnecessary in

the Securities Act, and that such legend is not required by law to appear on such certificate.

13. Indemnification.

13.1 Indemnification by Sellers for Representations and Warranties and Covenants of the Company. Except

as set forth in Section 13.4 and subject to the limitations set forth in this Section 13, Sellers shall jointly and
severally indemnify and hold harmless Purchaser and Parent against and in respect of any and all Liabilities,
losses, damages, claims, costs and expenses, including without limitation reasonable attorneys’ fees (collectively,
the “Losses”) imposed on, sustained, incurred or suffered by Purchaser or Parent, whether in respect of third-
party claims against the Company, Purchaser or Parent, claims among the Parties, or otherwise, arising out of,
resulting from, or due to (i) any breach of or inaccuracy in any representation or warranty set forth in Section 7
for the period such representation or warranty survives or (ii) any breach, violation or non-fulfillment of any
covenant or agreement of the Seller contained in this Agreement; provided, however, that each Seller shall be
severally, and not jointly, liable for such portion of the Losses arising out of, resulting from or due to the
foregoing, as exceeding the actual amount in the Escrow; provided, further, subject to the provisions of
Section 13.2, that such amount shall not exceed Thirteen Million and Five Hundred Thousand U.S. Dollars
(US$13,500,000).

13.2 Threshold and Cap. Sellers shall indemnify and hold harmless the Company, Purchaser and Parent with

respect to any Loss suffered by the Company, Purchaser or Parent under Sections 13.1 if, and only if, such Loss
together with the aggregate of all Losses theretofore incurred by the Purchaser or Parent under such Sections shall
exceed Nine Hundred Thousand U.S. Dollars (US$900,000) (the “Threshold”), in which case Sellers shall be
liable for the aggregate amount of all Losses suffered by the Purchaser or Parent, up to a maximum equal to the
Escrow Amount; provided, however, any Losses suffered by Purchaser or Parent with respect to inaccuracy of the
Projected Closing Balance Sheet as updated as of the Closing Date shall not be subject to such Threshold, but shall
be subject to the threshold set forth in Section 2.3(g), and provided, further that any Losses suffered by the
Purchaser or Parent with respect to fraud of the Company, or relating to Losses suffered as a result of breaches of
the representations and warranties set forth in Sections 7.2, 7.24 and 7.26 shall be not be subject to the Threshold
and shall be limited to the Purchase Price plus any Earn-Out actually paid to Sellers.

13.3 Indemnification by Sellers for Representations and Warranties of Sellers. Each Seller shall severally,
and not jointly, indemnify and hold harmless Purchaser and Parent against and in respect of any and all Losses
imposed on, sustained, incurred or suffered by Purchaser or Parent, whether in respect of third-party claims,
claims among the Parties, or otherwise, solely arising out of, resulting from, or due to any misrepresentation or
breach of warranty set forth in Section 6 (but only for misrepresentations or breaches of warranties by such Seller
and not by other Sellers) if, and only if, such Losses together with the aggregate of all Losses theretofore
incurred by the Purchaser or Parent under this Section 13 shall exceed the Threshold, in which case such Seller
shall be liable for the aggregate amount of all such Losses solely arising out of, resulting from, or due to its
misrepresentation or breach of warranty set forth in Section 6. The indemnification obligations of each Seller
other under this Section 13.3 shall be limited to the total amount of the Purchase Price received by such Seller as
shown on Schedule 2.2(f), except in the case of fraud, where no such limitation shall be in effect.

13.4 Indemnification by Purchaser and Parent for Their Representations and Warranties. Purchaser and

Parent shall jointly and severally indemnify, defend and hold harmless Sellers (and their respective heirs,
successors and permitted assigns) from, against and in respect of any Losses imposed on, sustained, incurred or
suffered by, or asserted against, any of Sellers, whether in respect of third-party claims, claims among the Parties,
or otherwise, arising out of, resulting from, or due to (i) any breach of or inaccuracy in any representation or
warranty set forth in Section 8 for the period such representation or warranty survives or (ii) any breach,
violation or non-fulfillment of any covenant or agreement of Purchaser or Parent contained in this Agreement.

13.5 Third-Party Claim Indemnification Procedure.

(a) If any written claim or demand, for which an indemnifying Party (an “Indemnifying Party”) may

have liability to any indemnified Party hereunder (an “Indemnified Party”), is asserted against or sought to

31

be collected from any Indemnified Party by a third party (a “Third-Party Claim”), such Indemnified Party
shall promptly (but no later than thirty (30) calendar days after receipt thereof) notify the Indemnifying
Party in writing of such Third-Party Claim (a “Third-Party Claim Notice,”); provided, however, that the
failure timely to give a Third-Party Claim Notice shall affect the rights of an Indemnified Party hereunder
only to the extent that such failure has a material prejudicial effect on the defenses or other rights available
to the Indemnifying Party with respect to such Third-Party Claim. A Third-Party Claim Notice shall contain
a brief summary of the facts underlying or relating to such claim to the extent then known by the
Indemnified Party or a copy of any correspondence or notice received from the relevant third party and a
statement that the Indemnified Party seeks indemnification for Losses relating to such Third-Party Claim.

(b) The Indemnifying Party shall have thirty (30) calendar days (or such lesser number of days set forth

in the Third-Party Claim Notice as may be required by any Governmental Authority or Governmental
Order) after receipt of the Third-Party Claim Notice (the “Notice Period”) to notify the Indemnified Party
that it desires to defend the Indemnified Party against such Third-Party Claim unless the Third Party Claim
involves criminal liability or in which equitable relief is sought against any of the Indemnified Parties; it
being understood that, by assuming the defense of a Third-Party Claim, the Indemnifying Party shall
acknowledge its obligation to indemnify the Indemnified Party with respect to all Losses imposed on,
sustained, incurred or suffered by, or asserted against the Indemnified Party in respect of such Third-Party
Claim (subject only to the limitations contained in Section 13.2 or 13.3, as the case may be, and any
amounts actually recovered as contemplated by Section 13.8) and all Losses sustained, incurred or suffered
by the Indemnified Party in connection with such defense prior to such assumption shall be reimbursed by
the Indemnifying Party.

(c) In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that
it desires to defend the Indemnified Party against a Third-Party Claim, the Indemnifying Party shall have the
right to defend the Indemnified Party by appropriate proceedings, with counsel selected by the Indemnifying
Party that is reasonably satisfactory to the Indemnified Party, at the expense of the Indemnifying Party.
Once the Indemnifying Party has duly assumed the defense of a Third-Party Claim, the Indemnified Party
shall have the right, but not the obligation, to participate in any such defense, including the opportunity to
participate in any discussions or correspondence with any Governmental Authority, and to employ separate
counsel of its choosing. The Indemnified Party shall participate in any such defense at its own expense
unless (i) the Indemnifying Party and the Indemnified Party are both named parties to the proceedings and
counsel to the Indemnified Party shall have reasonably concluded that representation of both parties by the
same counsel would be inappropriate due to actual or potential differing interests between them or the
availability to the Indemnified Party of one or more defenses or counterclaims that are inconsistent with one
or more of those that may be available to the Indemnifying Party in respect thereof, or (ii) the Indemnified
Party assumes the defense of a Third-Party Claim after the Indemnifying Party has failed to diligently
pursue a Third-Party Claim it has assumed, as provided in Section 13.5(d).

(d) If the Indemnifying Party (i) elects not to defend the Indemnified Party against a Third-Party Claim,

whether by not giving the Indemnified Party timely notice of its desire to so defend or otherwise, (ii) is not
entitled to defend the Third-Party Claim as provided in Section 13.5(b), or (iii) after assuming the defense of
a Third-Party Claim, fails to take reasonable steps necessary to negotiate for settlement or defend diligently
such Third-Party Claim within fifteen (15) calendar days after receiving written notice from the Indemnified
Party to the effect that the Indemnifying Party has so failed, the Indemnified Party shall have the right, but
not the obligation, to assume its own defense; it being understood that the Indemnified Party’s right to
indemnification for a Third-Party Claim shall not be adversely affected by assuming the defense of such
Third-Party Claim.

(e) Whether or not the Indemnifying Party shall have assumed defense of a Third-Party Claim, (i) the
Indemnified Party shall have no liability with respect to any settlement or compromise of such Third-Party
Claim effected without its written consent (which consent shall not be unreasonably withheld) and (ii) the

32

Indemnifying Party shall not, without the prior written consent of the Indemnified Party (which consent
shall not be unreasonably withheld), consent to the entry of judgment, admit any liability with respect to,
settle, compromise, discharge or offer to settle, compromise or discharge any Third-Party Claim on a basis
that would result in (A) the imposition of a consent order, injunction or decree that would restrict the future
activity or conduct of the Indemnified Party or any of its affiliates, (B) a finding or admission of a violation
of Law or violation of the rights of any Person by the Indemnified Party or any of its affiliates, (C) a finding
or admission of a violation of Law, of a violation of the rights of any Person or that would have an adverse
effect on other claims made or threatened against the Indemnified Party or any of its affiliates, or (D) except
to the extent within the basket set forth in Section 13.2 or 13.3, as the case may be, any monetary liability of
the Indemnified Party that will not be promptly paid or reimbursed by the Indemnifying Party or anything
less than a complete release being provided to the Indemnified Party and its affiliates.

(f) The Indemnified Party and the Indemnifying Party shall cooperate in order to ensure the proper and

adequate defense of a Third-Party Claim, including by providing access during regular business hours to each
other’s relevant business records and other documents, and employees; provided, however, that such
cooperation shall not unreasonably interfere with the business or operations of the providing party. All Losses
sustained, incurred or suffered by the Indemnified Party in connection with responding to, complying with or
satisfying the Indemnifying Party’s requests for cooperation shall be promptly reimbursed by the
Indemnifying Party. If the Indemnifying Party disputes the amount of, or otherwise refuses or fails to
reimburse, any such Losses that the Indemnified Party has incurred and for which the Indemnified Party has
sought reimbursement from the Indemnifying Party, the Indemnified Party shall not be obligated to continue
providing cooperation with respect to the defense of the relevant Third-Party Claim until such dispute has
become the subject of a Final Determination or all such Losses have been reimbursed in full.

(g) The Indemnified Party and the Indemnifying Party shall use reasonable best efforts to avoid
production of confidential information (consistent with applicable Law), and to cause all communications
among employees, counsel and others representing any party to a Third-Party Claim to be made so as to
preserve any applicable attorney-client or work-product privileges.

13.6 Direct Claim Indemnification Procedure.

(a) If an Indemnified Party wishes to make a claim for indemnification hereunder for a Loss that does

not result from a Third-Party Claim (a “Direct Claim”), the Indemnified Party shall notify the Indemnifying
Party in writing of such Direct Claim (a “Direct Claim Notice”), including a brief summary of the facts
underlying or related to such claim to the extent then known by the Indemnified Party and a statement that
the Indemnified Party seeks indemnification for Losses relating to such claim. The Indemnifying Party shall
have a period of thirty (30) calendar days within which to respond to such Direct Claim.

(b) If the Indemnifying Party accepts the Direct Claim or does not respond within such 30-day period,

the Indemnifying Party will be deemed to have accepted the Direct Claim and to have conclusively
acknowledged its obligation to indemnify the Indemnified Party with respect to all Losses imposed on,
sustained, incurred or suffered by, or asserted against the Indemnified Party in respect of such Direct Claim.
If the Indemnifying Party accepts or is deemed to accept the Direct Claim, within thirty (30) days after the
date of such acceptance, it shall pay the amount of Losses (if any) specified in the Direct Claim Notice for
which the Indemnified Party seeks indemnification at that time (which amount shall not be conclusive of the
final amount of such Direct Claim). In the event that the Indemnifying Party is Sellers or the Company, it
shall have the option to either pay the foregoing amount of Losses in cash or instruct the Escrow Agent to
release to Purchaser such portion of the Escrow Amount pursuant to the Escrow Agreement as directed by
the Sellers’ Representative.

(c) If the Indemnifying Party rejects all or any part of the Direct Claim within the 30-day period after

the date of the Direct Claim Notice, or fails to pay any Losses in accordance with Section 13.6(b), the

33

Indemnifying Party and the Indemnified Party shall use good faith efforts to resolve such dispute on the
Direct Claim during the 30-day period following the delivery of a response reflecting such dispute. If the
dispute is not resolved within such 30-day period, the Indemnifying Party and the Indemnified Party shall
submit the dispute to arbitration pursuant to Section 16.11 below.

13.7 Consequential Damages. The Parties acknowledge that Losses shall not include any consequential,

punitive, special, incidental and indirect damages, including lost profits.

13.8 Adjustments to Losses.

(a) Insurance. In calculating the amount of any Loss, the proceeds actually received by the Indemnified

Party or any of its affiliates under any insurance policy or pursuant to any claim, recovery, settlement or
payment by or against any other Person in each case relating to the Third-Party Claim or the Direct Claim,
net of any actual costs, expenses or premiums incurred in connection with securing or obtaining such
proceeds, shall be deducted, except to the extent that the adjustment itself would excuse, exclude or limit the
coverage of all or part of such Loss. The Indemnified Party shall make commercially reasonable efforts to
assert any rights or make any claim or demand under any insurance policy relating to any Third-Party Claim
or Direct Claim or any occurrence, claim or Loss that results in a payment by an Indemnifying Party under
this Section 13.8. No Indemnifying Party shall be entitled to be subrogated to any rights of an Indemnified
Party.

(b) Net Asset Adjustment. In calculating the amount of any Loss for which Purchaser or Parent is
entitled to indemnification hereunder, the amount of any reserve or other negative provision reflected in the
Closing Net Asset Statement related to such Loss shall be deducted.

(c) Reimbursement. If an Indemnified Party recovers an amount from a third party in respect of a Loss

that is the subject of indemnification hereunder after all or a portion of such Loss has been paid by an
Indemnifying Party pursuant to this Section 13, the Indemnified Party shall promptly remit to the
Indemnifying Party the excess (if any) of (i) the amount paid by the Indemnifying Party in respect of such
Loss (or, where Sellers are the Indemnifying Party, any amount paid by the Escrow Agent pursuant to the
Escrow Agreement), plus the amount actually received from the third party in respect thereof, less (ii) the
full amount of Loss.

(d) Payment by Escrow Agent. If, pursuant to the Escrow Agreement, Purchaser or Parent receives an

amount from the Escrow Agent in respect of a Loss that is the subject of indemnification by Sellers
hereunder, neither Purchaser nor Parent shall be entitled to seek enforcement of its rights to indemnification
directly against Sellers with respect to such amount. Notwithstanding anything to the contrary: (i) with
respect to each release to Parent and/or Purchaser from the Escrow (other than any releases arising from a
breach of Section 6 hereof, which shall be released only from the breaching Seller’s portion of the Escrow),
12.0% thereof shall be released from the cash portion of the Escrow and 88.0% thereof shall be released
from the share portion of the Escrow; and (ii) despite any appreciation of Parent’s American Depositary
Shares/Ordinary Shares, no release to Parent or Purchaser shall be made from the share portion of the
Escrow if the cumulative amount of releases therefrom has reached or exceeded US$13,500,000.

13.9 No Right of Set-Off. No Party shall have any right to set off any amounts owed under this Section 13

against any amounts (including, without limitation, any indemnification payment) owed under any other
provision of this Agreement or any Ancillary Agreement.

14. Survival of Representations, Warranties, Covenants and Indemnification Obligations.

14.1 General. Subject to Section 14.2, all representations, warranties, covenants and indemnification
obligations of the Sellers contained in this Agreement, or made pursuant hereto, shall survive the Closing and

16.4 Entire Agreement. This Agreement (including all Schedules and Exhibits hereto) and the agreements
referred to in or contemplated by this Agreement constitute the entire understanding and agreement among the
Parties and supersede any and all prior or contemporaneous, oral or written, representations, communications,
understandings and agreements among the Parties with respect to the subject matter hereof or thereof to the

all Parties. All amendments or modifications of this Agreement shall be binding upon the Parties despite any lack
of consideration so long as the same shall be in writing and executed by the Parties.

16.7 Waiver. The performance of any obligation required of a Party hereunder may be waived only by a
written waiver signed by the other Parties, and such waiver shall be effective only with respect to the specific

36

obligation described. The waiver by any Party of a breach of any provision of this Agreement by any other Party
shall not operate or be construed as a waiver of any subsequent breach of the same provision or another provision
of this Agreement.

16.8 Assignment. Neither this Agreement nor any right or obligation hereunder may be assigned by any

Party without the prior written consent of the other Parties, and any attempted assignment without the required
consents shall be void.

16.9 Severability. If any provision hereof is found invalid, illegal or unenforceable pursuant to any

Governmental Order, the remainder of this Agreement shall remain valid, legal and enforceable according to its
terms, and such invalid, illegal or unenforceable provision shall be replaced with a provision that approximates
the substance and spirit of the invalid, illegal or unenforceable provision as closely as possible without being
invalid, illegal or unenforceable.

16.10 Governing Law. This Agreement and all disputes arising out of or in connection with this Agreement
shall be governed by, interpreted under, and construed and enforceable in accordance with, the laws of the State
of New York, U.S.A., without giving effect to conflict of law principles.

16.11 Arbitration. Any dispute, controversy or difference arising among the Parties out of or in relation to
this Agreement or for the breach thereof shall be resolved exclusively by arbitration in the Hong Kong Special
Administrative Region of the Peoples’ Republic of China. Such arbitration shall be conducted in the English
language in accordance with the Rules of Arbitration of the International Chamber of Commerce by three
(3) arbitrators, of whom one shall be appointed by Purchaser and/or Parent, another shall be appointed by Sellers,
and the third shall be appointed by the first two (2) arbitrators. If the third arbitrator is not so appointed within
one (1) month after the appointment of the first two (2) arbitrators, the third arbitrator shall be selected in
accordance with the Rules of Arbitration of the International Chamber of Commerce. The decision of the
arbitrators shall be made on the principles of majority rule. The award made by the arbitrators shall be final and
binding upon the Parties and may be enforced in any court of competent jurisdiction. Notwithstanding the
foregoing provision, the Parties shall have the right to bring judicial proceedings to obtain preliminary injunctive
relief at any time during the pendency of arbitration proceedings, provided that such preliminary injunctive relief
shall be subject to final arbitral decisions. Unless the arbitrators decide otherwise, the cost of arbitration shall be
shared equally by Purchaser and/or Parent, on the one hand, and Sellers, on the other hand.

(a) No Party shall disclose, disseminate or cause to be disclosed the terms and conditions of this
Agreement, except insofar as disclosure is reasonably necessary to carry out and effectuate the terms of this
Agreement or as required by a court of competent jurisdiction or governmental agency, and insofar as any
Party is required by Law to disclose.

(b) Purchaser shall treat as confidential and shall safeguard any and all information, knowledge or data

included in any information relating to the business of the Seller and its affiliates other than the Business
that becomes known to Purchaser as a result of the transactions contemplated by this Agreement except as
otherwise agreed to by the Seller in writing, in each case by using the same degree of care, but no less than a
reasonable standard of care, to prevent the unauthorized use, dissemination or disclosure of such
information, knowledge and data as Purchaser used with respect to its own confidential information;
provided, however, that nothing in this Section 16.16 shall prevent the disclosure of any such information,
knowledge or data to any Representatives of Purchaser who reasonably need to know such information for
the purposes of negotiating this Agreement and carrying out the transactions contemplated hereby.

(c) Purchaser, Parent and Sellers acknowledge that the confidentiality obligations set forth herein shall

not extend to information, knowledge and data that is publicly available or becomes publicly available
through no act or omission of the party owing a duty of confidentiality, or becomes available on a
non-confidential basis from a source other than the party owing a duty of confidentiality so long as such
source is not known by such party to be bound by a confidentiality agreement with or other obligations of
secrecy to the relevant other Party or required to be disclosed by a Governmental Authority.

(d) In the event of a breach of the obligations hereunder by Purchaser, Parent or Sellers, the
non-breaching Parties, in addition to all other available remedies, will be entitled to injunctive relief to
enforce the provisions of this Section 16.16 in any court of competent jurisdiction.

16.17 Language. The English language shall be the language used for the interpretation of this Agreement.

17. Parent Guarantee.

17.1 Parent hereby unconditionally guarantees the due and punctual payment and performance of all of
Purchaser’s obligations set forth in this Agreement. This guaranty is an irrevocable guaranty of payment (and not
just of collection) and shall continue in effect notwithstanding any extension or modification of the terms of this
Agreement, any assumption of any such guaranteed obligation by any other party or any other act or event that
might otherwise operate as a legal or equitable discharge of Parent under this Section 17. So long as any
obligation of Purchaser to Sellers under this Agreement remains unpaid or undischarged, Parent hereby waives
(but only with respect to Sellers and not as to any other parties) all rights to subrogation arising out of any
payment by Parent under this Section 17.

17.2 The obligations of Parent hereunder shall be absolute and unconditional irrespective of the validity,
legality or enforceability of this Agreement or any other document related hereto, and shall not be affected by or
contingent upon (a) the liquidation or dissolution of, or the merger or consolidation of Purchaser with or into any
corporation, or any sale or transfer by Purchaser of all or part of its property or assets, (b) the bankruptcy,
receivership, insolvency, reorganization or similar proceedings involving or affecting Purchaser, (c) any
modification, alteration, amendment or addition of or to this Agreement, or (d) any disability or any other
defense of the Purchaser or any other person and any other circumstance whatsoever (with or without notice to or
knowledge of Parent) which may or might in any manner or to any extent vary the risks of Parent or might
otherwise constitute a legal or equitable discharge of a surety or a guarantor or otherwise.

39

17.3 Parent hereby waives all special suretyship defenses and protest, notice of protest, demand for
performance, diligence, notice of any other action at any time taken or omitted by Sellers and, generally, all
demands and notices of every kind in connection with this Section 17 and the Purchaser’s obligations hereby
guaranteed, and which Parent may otherwise assert against Sellers.

17.4 This Section 17 shall continue to be effective or shall be reinstated, as the case may be, if at any time

payment or performance of any of the obligations of the Purchaser under this Agreement is rescinded or must
otherwise be restored or returned by Sellers upon the insolvency, bankruptcy or reorganization of the Purchaser
or otherwise.

17.5 Parent acknowledges that each of the waivers set forth above is made with full knowledge of its
significance and consequences and under the circumstances the waivers are reasonable and not contrary to public
policy. If any of said waivers is determined to be contrary to any applicable law or public policy, such waivers
shall be effective only to the extent permitted by Law.
