PART I



|Item 1. | Business
|------- | --------

We provide advanced
semiconductor sensor and system solutions based on integrated micro electro-mechanical systems, or MEMS, technology and mixed signal circuit design. Our accelerometer products are used to measure tilt, shock, vibration and acceleration, and have a
wide range of applications such as mobile phones, automotive safety systems and video projectors. We combine proprietary thermal-based MEMS technology and advanced analog mixed signal processing circuitry design into a single chip using a standard
complementary metal-oxide semiconductor, or CMOS, process. We believe that this approach allows us to provide sensor solutions at a lower cost, with higher performance and greater functionality than our competitors. In addition, our technology
platform allows us to easily integrate additional functions or create new sensors to expand into magnetic, touch and flow sensors and related applications.

Any product that requires the control or measurement of motion is a potential application for accelerometers. For example, in mobile phones, accelerometers enable a variety of value-added functions such as image
orientation, gaming control and text scrolling. In automotive applications, accelerometers are being deployed in airbag, electronic stability control, rollover protection, and navigation systems. In consumer applications, accelerometers are used in
global positioning systems, video gaming systems and interactive toys. Industrial and medical applications include inclination sensing, earthquake detection and cardiac pacemakers.

We are also capitalizing on our proprietary MEMS technology to develop new types of sensor solutions that will broaden our market opportunities. For
example, we recently introduced a new line of MEMS-based magnetic sensors that provide enhanced digital compass capabilities for mobile applications such as cell phones and personal navigation devices. During 2008, we also established our industrial
solutions business unit, and acquired technology related to a MEMS-based gas-flow meter for use in industrial applications, which we expect to introduce in late 2009.

We shipped approximately 46 million units from 2004 through 2008. Our products have been used by leading international and China-based manufacturers. We are a pioneer in providing accelerometers to Chinas
fast-growing mobile phone market and are among the leading providers of accelerometers for image projectors, supplying to several Japanese OEMs. Our largest automotive customer is Autoliv Inc., a leading European automotive safety systems supplier.

We manufacture our products utilizing a semi-fabless model by outsourcing the production of CMOS wafers and completing the
post-CMOS MEMS process in-house. By outsourcing the standard CMOS manufacturing process, we are able to leverage mature semiconductor infrastructure and standard wafer fabrication processes and, in turn, more efficiently manage our capital
expenditures. Moreover, we believe that retaining the key MEMS manufacturing process in-house enables us to protect and retain control over our key proprietary technology more effectively and to create a higher barrier to entry.

Founded in March 1999, we are headquartered in Andover, Massachusetts and have engineering and manufacturing facilities in Wuxi, Jiangsu Province, China.
We conduct research and development at our facilities in Andover, Wuxi and Chicago, Illinois. Our research and development teams work closely with each other in our product and technology research and development activities. This enables us to
access experienced and creative design talent in the United States, while benefiting from competitive engineering and manufacturing costs in China. In addition, our presence in China places us in close proximity to the supply chain for the large
Chinese markets for mobile phones and consumer electronics.

We have experienced significant growth since our products were first
commercialized in 2001. In 2007, 2006, and 2005, our net sales totaled $25.3 million, $13.1 million and $9.1 million, respectively. The increases in our unit sales volume and sales revenue during this period were primarily attributable to increases
in the sale of our products for mobile phone applications and automotive applications. In 2008, however, our net sales have



1

##### Table of Contents

been adversely affected by a number of factors, including a slowdown in the mobile handset market in China, the May 2008 earthquake in China, and more
recently, the effects of the current global recession. Our net sales for the period ended December 31, 2008 were $20.1 million. In 2008 and 2007, our net income (loss) totaled ($1.7) million and $6.1 million, respectively. A major contributor
to our net loss in 2008 was costs related to our Olympic torch project.

Industry Overview

Sensors are a category of analog semiconductors that measure the strength or presence of a physical property such as voltage, current, temperature,
pressure, weight, light, sound or speed. MEMS-based sensors incorporate a micro electro-mechanical system as the active sensing function while the integrated analog circuitry provides an electronic interface. As digital semiconductors
become more technologically advanced, analog and mixed-signal semiconductor devices that interface with them, such as sensors, must also operate with greater speed, accuracy and efficiency.

Sensors based on MEMS are used for motion, direction and pressure sensing applications. Examples include accelerometers which are used to measure
acceleration or gravitational forces, pressure sensors and gyroscopes which are used for sensing rotational motion. The market for MEMS sensors is expected to expand as functions and products enabled by MEMS sensor solutions achieve broader
penetration in the mobile phone, consumer, automotive, aerospace, medical and industrial markets. We expect that as MEMS technology advances, it will enable electronic systems to become smaller, faster, more energy-efficient and less expensive.

In the last three years, the mobile phone handset market has accounted for the largest component of our net sales. Although our net sales
into this market declined in 2008, we believe that the mobile phone market continues to offer growth opportunities for sales of MEMS sensors, as functionality based on accelerometers increasingly becomes a standard feature of current cell phones.
MEMS sensors are also increasingly employed in other consumer applications. Accelerometers have a wide range of applications for consumer electronics, including projectors, laptop computers, personal navigation systems, audio players, digital
cameras and gaming controls. Future growth areas in consumer applications for accelerometers may include video game controls and childrens toys, where increasingly sophisticated and interactive applications are being incorporated. As
technology advances, manufacturers software developers and other solution providers have introduced products integrating accelerometers that enable applications such as picture orientation, gaming control and navigation, as well as a broad range of
location-based services. Other potential growth markets for MEMS sensors include aerospace, medical and industrial applications.

The
automotive industry is also a major market for our MEMS sensor systems. MEMS sensors have become essential in a variety of automotive applications for improving passenger safety and comfort. They have been employed in airbag deployment systems,
which were the first high-volume application for MEMS sensors, rollover detection, electronic stability control, navigation, vehicle security and tire pressure monitoring systems. In rollover detection systems, accelerometers can measure the roll
axis of a vehicle, and upon determining that a rollover is imminent, deploy passenger safety devices before the tire is lifted from the ground. Accelerometers are also used to sense under-steer or over-steer in electronic stability control systems
which can then apply braking force to wheels and/or reduce excess engine power. Key factors contributing to the increasing use of MEMS sensors in the automotive market include the adoption of heightened safety standards in developing countries such
as China and India, increased demand for electronic stability control and rollover safety systems, and growth in the use of navigation systems.

To promote growth of the MEMS sensor market, manufacturers continuously provide more integrated system-level solutions, reduce costs to enable mass-market adoption for consumer applications (generally a more price-sensitive market), deliver
products with increased portability for increasingly smaller devices and develop products with greater functionality.

Our Competitive Strengths

Our key competitive strengths include the following:

Proprietary technology enabling superior
reliability, functionality and pricing. We have proprietary rights to produce MEMS accelerometers based on a unique thermal technology which has higher shock tolerance, lower failure rate and lower cost relative to alternative mechanical
solutions. Our accelerometers can be manufactured on a standard CMOS process with on-chip mixed signal processing, which enables us to enhance reliability and reduces our production cost. This standardized process enables us to easily integrate
additional functions or create new sensors for MEMS applications beyond accelerometers and expand into the magnetic, touch and flow sensor markets.

Comprehensive system solutions offering. Our solutions involve the development of a fully-integrated sensor system on a chip, together with the reference designs, algorithms, source code and, in some cases, the application
content to facilitate rapid commercial introduction. For example, our new line of magnetic sensors incorporates our Intelligent Heading Correction (IHC) algorithms, which automatically calibrate the device and, compensate for the extraneous magnetic
interference, providing high accuracy and promoting ease of use. Integrated Solutions such as this enable our customers to shorten their product development cycle and allow for rapid adoption of our products in new applications.

Leading market position and established customer relationships. We are a pioneer in providing accelerometers to Chinas large mobile
phone market. We are also among the leading sensor providers in a diverse range of other applications such as key-stone screen adjustment sensors for image projectors, supplying to several Japanese OEMs. In addition, our accelerometers are
incorporated in rollover protection devices for the automotive market where Autoliv Inc. is a major customer. We have developed close working relationships with our customers and regularly work together with them on new applications development.

Efficient semi-fabless manufacturing model creating higher entry barrier. Our semi-fabless model reduces capital expenditures
while retaining manufacturing control over key MEMS-based process steps. We outsource the production of standard CMOS wafers, which we consider to be a commodity, to our foundry service provider, and perform in-house the proprietary post-CMOS MEMS
process of building MEMS on top of the standard CMOS wafer. We believe that by performing proprietary manufacturing processes in-house, we create a higher barrier to entry.

Strong technology-driven management team. Our management team has extensive experience in the MEMS and integrated circuit design industry.
Our founder and CEO, Dr. Yang Zhao, has been dedicated to the research and development of MEMS sensors since the early 1990s while he was doctoral student at Princeton University, and is named as an inventor on eight patents we own and
three of our pending patent applications in the United States. Furthermore, our management team has successfully guided us through our rapid business expansion while maintaining focus on the development and expansion of our core technological
capabilities.

Our Strategy

Key
elements of our strategy for growth include the following:

Increase penetration of existing markets and customers. We are
actively seeking design wins by capitalizing on existing relationships with major OEM customers in the automotive, industrial and business tools markets in China, Taiwan, Japan, Europe and the United States. While we currently provide a limited
range of products to our existing customers, we are focused on expanding these relationships to broaden the adoption of our solutions across additional product lines and applications.

Diversify into new sensor and integrated products. We have a strong foundation and the capabilities to diversify into new sensor products,
including magnetic, temperature, pressure, gyroscopes and flow sensors. Emerging applications for sensors typically lack incumbent competitors, thereby providing an opportunity for a



3

##### Table of Contents

first-mover to define the dominant application technology. We also believe that there is an opportunity in integrated sensor products, which combine multiple
sensing devices onto one chip.

Maintain cost leadership. We intend to maintain our cost advantage by developing new innovative
proprietary technologies, focusing on designing products on readily available foundry processes, and leveraging our low-cost manufacturing capabilities in China.

Leverage cross-continental research and development model to strengthen technology platform. We have research and development teams in Andover, Chicago and Wuxi that work closely with each other in our
product and technology research and development activities. Our U.S. team is responsible for original research and development activities while our China team focuses on implementing the technology developed by our U.S. team. We believe that this
cross-continental research and development model keeps us at the forefront of MEMS accelerometer research while maintaining a competitive cost base.

Engage in selective acquisitions to build new MEMS capabilities. We intend to evaluate and potentially make acquisitions of technologies and businesses that are complementary to our product portfolio, such
as our 2008 acquisition of industrial gas-flow meter technology from MEMStron. We believe that there is a large market potential for integrated system-on-chip sensor products which incorporate multiple types of sensors. While we develop our
technologies in-house, we are also actively seeking opportunities to acquire or license key technologies from third parties as well. We believe our strong core technology platform will also provide us an advantage in integrating the acquired
technologies to create a broader range of sensor solutions products in the market.

Risks Relating to Our
Business and Industry

The current global recession and related credit crisis are likely to adversely affect our business, results of operations
and financial condition.

The U.S. and other global economies are currently experiencing a recession that has affected all sectors
of the economy and that has continued to deepen, resulting in declines in economic growth and consumer confidence, increases in unemployment rates and uncertainty about economic stability. Global credit and financial markets are also experiencing
extreme disruptions, including diminished liquidity and credit availability and rapid fluctuations in market valuations. Our business has been affected by these conditions and is likely to be affected by them in the future, and there is no
certainty that economic conditions will not deteriorate further. These uncertainties affect businesses such as ours in a number of ways, making it difficult to accurately forecast and plan our future business activities. Deteriorating economic
conditions may lead consumers and businesses to continue to postpone spending, which may cause our customers to cancel, decrease or delay their existing and future orders with us. In addition, the inability of customers to obtain credit could
negatively affect our revenues and our ability to collect receivables. In addition, financial difficulties experienced by our suppliers or distributors could result in product delays, increased accounts receivable defaults and inventory challenges.
If the current uncertain economic conditions continue or further deteriorate, we could be required to record charges relating to restructuring costs or the impairment of assets and our business and results of operations could be materially and
adversely affected. These trends could have a material adverse impact on our business, our ability to achieve targeted results of operations and our financial condition as a result of, among other things:



| |  |  | reduced demand for our products, particularly in industries such as the automotive industry that have been severely affected by the global recession;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | increased risk of order cancellations or delays;
| | - |  | ------------------------------------------------

| |  |  | increased pressure on the prices for our products, such as we have already experienced in the handset market in China;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | greater difficulty in collecting accounts receivable; and
| | - |  | ---------------------------------------------------------



| |  |  | risks to our liquidity, including the possibility that we might not have access to our cash and investments when needed.
| | - |  | ------------------------------------------------------------------------------------------------------------------------

We are unable to predict the likely duration and severity of the current global downturn and disruption in credit and financial markets, but the longer
the duration the greater the risks we face in operating our business.

Our limited operating history makes it difficult to evaluate our business and
prospects.

We commenced operations in 1999, began to generate revenue in 2001, and first became profitable in 2004. Our limited
operating history may not provide a meaningful basis for evaluating our business and prospects. Our net sales and net income grew significantly from 2001 to 2007 but slowed in 2008. Our net sales were $20.1 million in 2008, $25.3 million in 2007 and
$13.1 million in 2006. Our net income (loss) were ($1.7) million in 2008, $6.1 million in 2007 and $0.5 million in 2006. We cannot accurately predict the duration or severity of the current adverse economic conditions or their impact on our
customers demand for our products, and as a result, it is difficult for us at this time to reliably forecast our longer-term revenues or results of operations. While we expect our revenues to increase modestly in the first quarter of 2009
based primarily on larger-than-expected orders from handset manufacturers in China, we do not expect to be profitable in the quarter. The outlook beyond the first quarter of 2009 is uncertain. Accordingly, you should not rely on the results of any
prior periods as indicative of our future revenue or net income growth or financial results. You should consider our business and prospects in light of the risks and uncertainties experienced by entrepreneurial companies seeking to develop products
in a rapidly-changing market. Some of these risks and uncertainties relate to our ability to:



| |  |  | maintain our sales growth and profit margin;
| | - |  | --------------------------------------------



| |  |  | preserve our position in the MEMS sensor market;
| | - |  | ------------------------------------------------



| |  |  | manage our expanding operations and product offerings;
| | - |  | ------------------------------------------------------



| |  |  | expand manufacturing capacity in time to meet surges in market demand;
| | - |  | ----------------------------------------------------------------------



| |  |  | manage our relationships with our service providers and suppliers, including our ability to obtain manufacturing capacity from semiconductor foundries during surges
in market demand;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | develop and deliver new products successfully; and
| | - |  | --------------------------------------------------



| |  |  | successfully integrate any future acquisitions.
| | - |  | -----------------------------------------------

If we are unsuccessful in addressing any of these risks and uncertainties, our business, financial condition and results of operations may be materially and adversely affected.

Our quarterly and annual operating results have fluctuated and may continue to fluctuate and are difficult to predict and if we do not meet financial expectations
of securities analysts or investors, the price of our common stock will likely decline.

Our quarterly and annual operating results
have fluctuated and may continue to fluctuate as a result of a number of factors, many of which are beyond our control. Comparing our operating results on a period-to-period basis may not be meaningful, and you should not rely on our past results as
an indication of our future performance. Our quarterly and annual net sales and profit margin may be significantly different from our historical amounts, and in future periods may fall below expectations. In particular, our gross margins declined
significantly in 2008, and could continue to decline. These and other risks described in this Risk Factors section, including the following factors, could cause our quarterly and annual operating results to fluctuate from period to
period:



| |  |  | the loss of one or more of our key customers;
| | - |  | ---------------------------------------------



7

##### Table of Contents

| |  |  | the cancellation or deferral of customer orders in anticipation of our new products or product enhancements, or due to a reduction in our customers end
demand;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in the price we charge for our products or our pricing strategies, which may be impacted by economic conditions or the pricing strategies of our
competitors;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the cyclicality of the semiconductor industry and seasonality in sales of products into which our products are incorporated;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | seasonal fluctuations of some of our product application markets as well as geographical markets; and
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | the length of the product development cycle for our new products.
| | - |  | -----------------------------------------------------------------

In addition, we plan our operating expenses, including research and development expenses, hiring of additional personnel and investments in inventory, in part on our expectations of future revenue, and our expenses
are relatively fixed in the short term. We have recently implemented cost reduction measures to reduce our operating expenses. However, if revenue for a particular quarter is lower than we expect, we may be unable to proportionately reduce our
operating expenses for that quarter, which would harm our operating results for that quarter. If our operating results in future quarters fall below the expectations of securities analysts or investors, the market price of our common stock will
likely decline.

The average selling prices of products in our markets have historically decreased rapidly and will likely do so in the future, which
could harm our revenue and gross margins.

In the semiconductor industry, the average selling price of a product typically declines
significantly over the life of the product. In the past, we have reduced the average selling prices of our products in anticipation of future competitive pricing pressures, new product introductions by us or our competitors and other factors. We
expect that we will have to similarly reduce our products average selling prices over the life of any particular product in the future. Reductions in our average selling prices to one customer could also impact our average selling prices to
other customers. A decline in average selling prices can harm our gross margins. For example, our gross margins have declined from 65.1% in 2007 to 47.9% in 2008, primarily as a result of decreasing unit prices in response to competitive pressures
in the mobile handset market. Our financial results will suffer if we are unable to offset reductions in our average selling prices by increasing our sales volumes, reducing our costs, adding new features to our existing products or developing new
or enhanced products on a timely basis with higher selling prices or gross margins.

We may not be able to compete effectively and increase or
maintain revenue and market share.

We may not be able to compete successfully against current or future competitors. If we do not
compete successfully, our market share and revenue may decline. We and our distributors currently sell substantially all of our accelerometer products to original equipment manufacturers, or OEMs, and original design manufacturers, or ODMs. We face
competition primarily from traditional capacitive/piezoresistive-based accelerometer manufacturers. Most of our current competitors have longer operating histories, significantly greater resources, brand recognition and a larger base of customers
than we do. In addition, these competitors may have greater credibility with our existing or potential customers. Moreover, many of our competitors have been doing business with customers for a longer period of time and have established
relationships, which may provide them with information regarding future market trends and requirements that may not be available to us. Additionally, some of our larger competitors may be able to provide greater incentives to customers through
rebates and similar programs. Some of our competitors with multiple product lines may bundle their products to offer a broader product portfolio or integrate accelerometer functionality into other products that we do not sell. These factors may make
it difficult for us to gain or maintain market share.

Our ability to grow depends on our ability to secure and maintain relationships with OEM and ODM customers. If we
cannot continue to achieve design wins, if our design wins do not result in large volume orders, or if we fail to meet an OEMs development and service demands, our ability to grow will be limited.

Our ability to grow depends on our ability to continue to achieve design wins with OEMs and ODMs to whom we sell either directly or through our
distributors. In order to achieve a design win, where our product is incorporated into an OEMs or ODMs product design, we may often need to make modifications to our products or develop new products that involve significant technological
challenges. We may also incur significant product development costs by participating in lengthy field trials and extensive qualification programs. We cannot assure you that these efforts would result in a design win.

Furthermore, a design win is not a binding commitment to purchase our products and may not result in large volume orders of our products. Rather, it is a
decision by an OEM or ODM to use our products in the design process of that OEMs or ODMs products. OEMs and ODMs can choose at any time to stop using our products in their designs or product development efforts. Moreover, even if our
products were chosen to be incorporated into an OEMs or ODMs products, our ability to generate significant revenues from that OEM or ODM will depend on the commercial success of their products. Thus, a design win may not necessarily
generate significant revenues if our customers products are not commercially successful.

In addition, OEMs and ODMs place
considerable pressure on us to meet their tight development schedules. These customers also often require extensive and localized customer support. As a result, we may be required to significantly expand our customer support organization. Devoting a
substantial amount of our limited resources to one or more of these customer relationships could result in opportunity costs which detract or delay us from completing other important product development projects for our other existing customers,
which could in turn impair our relationships with existing customers and negatively impact sales of the products under development.

We do not have
long-term purchase commitments from our customers, including OEMs and ODMs, and our ability to accurately forecast demand for and sales of our products is limited, which may result in excess or insufficient inventory and significant uncertainty and
volatility with respect to our revenue from period to period.

We do not have long-term purchase commitments from our customers,
including OEMs and ODMs. Our customers may cancel or reschedule purchase orders. Our customers purchase orders may vary significantly from period to period, and it is difficult to forecast future order quantities. The lead time required by our
foundry providers for wafer production is typically longer than the lead time that our customers provide to us for delivery of our products to them. Therefore, to ensure availability of our products for our customers, we typically ask our foundry
providers to start wafer production based on forecasts provided by our customers in advance of receiving purchase orders. However, these forecasts are not binding purchase commitments, and we do not recognize revenue until our products are shipped
to customers. Accordingly, we incur inventory and manufacturing costs in advance of anticipated sales. We cannot assure you that any of our customers will continue to place purchase orders with us in the future at the same level as in prior periods
or that the volume of our customers purchase orders will be consistent with our expectations when we plan our expenditures in advance of receiving purchase orders. Our anticipated demand for our products may not materialize. In addition,
manufacturing based on customer forecasts exposes us to risks of high inventory carrying costs and increased product obsolescence, which may increase our costs. If we overestimate demand for our products, or if purchase orders are cancelled or
shipments are delayed, we may be left with excess inventory that we cannot sell. Conversely, if we underestimate demand, we may not have sufficient inventory and may lose market share and damage our customer relationships. Obtaining additional
supply in the face of product shortages may be costly or impossible, particularly in the short term, which could prevent us from fulfilling orders. As a result, our results of operations may fluctuate significantly from period to period in the
future.

The length of our sales cycle is unpredictable, which makes it difficult for us to forecast revenue and may
increase the volatility of our operating results.

We have a lengthy sales cycle that typically begins with our receipt of an
initial request from a customer and ends when our customer executes a purchase order for production quantities. We typically need to obtain a design win to receive purchase orders. In some cases, due to the rapid growth of new product applications
and technologies, this process can be time-consuming and requires substantial investment of our time and resources. In addition, our OEM and ODM customers may require significant time to test, evaluate and design our products into their products.
Following a design win, OEMs and ODMs may need several months to begin large-volume production of the products that incorporate our products. Many factors beyond our control could affect the length of the sales cycle of our products. The
uncertainties on the sales cycle length makes it difficult for us to forecast our revenue and may increase the volatility of our operating results.

We depend and expect to continue to depend on a limited number of customers for a high percentage of our revenues. As a result, the loss of, or a significant reduction in orders from, any of these customers would significantly reduce
our revenues and harm our results of operations.

For 2008, each of five customers accounted for 10% or more of our net sales,
consisting of four distributors that accounted in aggregate for 57.8% of our net sales, and an OEM as to 21.0% of our net sales. For 2007, each of two customers accounted for 10% or more of our net sales, consisting of one distributor as to 55.3%
and an OEM as to 16.3%. If a large distributor or other customer purchases fewer of our products, defers orders or fails to place additional orders with us, our revenue could decline, and our operating results may not meet market expectations. In
addition, we face credit risks on some of our significant customers that are smaller companies. If those customers order our products, but fail to pay on time or at all, our liquidity and operating results could be materially and adversely affected.

Our success depends upon our customers ability to successfully sell their products.

The success of our products depends, in significant part, on the success of our customers products that incorporate our products. Most of our net
sales in 2007 and 2008 were attributable to accelerometer products that were incorporated into products such as mobile phones, projectors and automobile parts. If any of our customers are unsuccessful in their sales, whether due to lack of market
acceptance of their products, general industry slowdown, changes in the product supply chain or otherwise, our sales could be adversely affected. We are not certain whether these customers will be able to achieve success in their business or whether
they will remain competitive in their business even if initially successful.

We rely principally on one third-party foundry to manufacture wafers,
which are significant components in our manufacturing process. If we are unable to secure sufficient supply of wafers, or if the wafers supplied to us do not meet our quality standards, we may be unable to ship finished products and our customer
relationships may be damaged.

We currently rely on one foundry service provider to manufacture wafers used in our accelerometer
products. We also entered into agreements in 2006 with two additional foundry service providers to supply wafers used for magnetic sensors.

Because we outsource our wafer production, which is a critical part of our manufacturing process, we face several significant risks, including:



| |  |  | lack of manufacturing capacity at these foundries;
| | - |  | --------------------------------------------------



| |  |  | limited control over delivery schedules, quality assurance and control, manufacturing yields and production costs; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | the unavailability of, or potential delays in obtaining access to, key process technologies.
| | - |  | --------------------------------------------------------------------------------------------

##### Table of Contents

The ability of these foundries to provide us with wafers is limited by their available capacity. We do
not have a guaranteed level of production capacity with our principal foundry and it is difficult to accurately forecast our capacity needs. Furthermore, we do not have a long-term agreement with this foundry and we place our orders on a purchase
order basis. As a result, if it raises its prices or is not able to meet our required capacity for any reason, including shortages or delays in shipment of semiconductor equipment or materials it uses to manufacture our wafers, or if our business
relationship with our principal foundry deteriorates, we may not be able to obtain the required capacity from it and would have to seek alternative foundries, which may not be available on commercially reasonable terms, or at all. Using foundries
with which we have no established relationships could expose us to potentially unfavorable pricing, unsatisfactory quality or insufficient capacity allocation.

Furthermore, our principal foundry can allocate capacity to the production of other companies products and reduce deliveries to us on short notice. Many of its customers are larger than we are and may have
long-term agreements with the foundry and may receive preferential treatment from it in terms of capacity allocation. Reallocation of capacity by the foundry to its other customers could impair our ability to secure the supply of wafers that we
need, which could significantly delay our ability to ship our products, causing a loss of revenue and damage to our customer relationships. In addition, if we underestimate our needs for foundry capacity, our foundry may not have available capacity
to meet our immediate needs or we may be required to pay higher costs to fulfill those needs, either of which could materially and adversely affect our business, operating results or financial condition.

Our key foundry service provider maintains facilities that are located in a region that is subject to earthquakes, typhoons and other natural disasters, as well as
geopolitical risks and social upheaval.

Currently, all of the wafers used in our accelerometers are manufactured by a foundry in
Taiwan. Taiwan is susceptible to earthquakes, typhoons, flood and other natural disasters, and has experienced severe earthquakes and typhoons in recent years that caused significant property damage and loss of life. In addition, this foundry is
subject to risks associated with uncertain political, economic and other conditions in Taiwan and elsewhere in Asia, such as political turmoil in the region and the outbreak of contagious diseases, such as Severe Acute Respiratory Syndrome, or SARS,
or any other epidemic such as avian flu. The occurrence of any of the foregoing could disrupt the foundrys operations, resulting in significant disruption or delays in deliveries of raw materials for our operations. As a result, our business
operations could be significantly disrupted and deliveries of our products could be delayed.

Our products are complex and defects in our products
could result in a loss of customers, damage to our reputation, decreased revenue, unexpected expenses, loss of market share and warranty and product liability claims.

Our products are complex and must meet our customers stringent quality requirements. Such complex products may contain undetected errors or defects,
especially when first introduced or when new versions are released. For example, our products may contain errors that are not detected until after they are shipped because we cannot test for all possible scenarios. Errors or defects can arise due to
design flaws, defects in materials or components or as a result of manufacturing difficulties, which can affect both the quality and yield of the product. As our products become more complex, we face significantly higher risk of undetected defects.
Any errors or defects in our products, or the perception that there may be errors or defects in our products, could result in customer rejection of our products, damage to our reputation, lost revenue, diversion of development resources and
increases in customer service and support costs and warranty claims.

Failure of suppliers to deliver on a timely basis sufficient quantities of
components or materials or licensed software used in our products may result in delays or other disruptions in introducing or shipping our products, which could adversely affect our business and operating results.

Some of the components, materials and software used in our products are purchased or licensed from a limited number of suppliers and it is difficult for
us to redesign our products to incorporate components,



11

##### Table of Contents

materials or software from alternative suppliers. For example, we obtain the ceramic packaging materials that we use on our accelerometer products from only
two suppliers. In addition, we purchase rights to media content developed for our accelerometer products sold to our mobile phone end-customers. If any of our suppliers terminates its relationship with us, or is unable to deliver components,
materials or software in accordance with our requirements, we may not be able to find alternative sources on favorable terms on short notice. Our inability to find or develop alternative sources of components, materials and software, if and as
required, could result in delays or other disruptions in introducing or shipping our products. If any of these events occur, our business and operating results could be adversely affected.

Our success depends on the continuing efforts of our senior management team and other key personnel and on our ability to successfully attract, train and retain
additional key personnel.

Our future success depends heavily upon the continuing services of the members of our senior management
team and various engineering and other technical personnel. In particular, our founder, Chief Executive Officer and director, Dr. Yang Zhao, was and remains central to the development and advancement of the thermal MEMS technology on which our
accelerometer products have been designed and developed. In addition, our engineers and other technical personnel are critical to our future technological and product innovations. We have experienced significant turnover among our senior
executive personnel since our initial public offering, including our termination in January 2009 of our Vice President of Engineering and the resignations of our Vice President of Marketing and Business Development in December
2008, of our Chief Financial Officer in June 2008 and of our Vice President and General Manager in January 2008. If Dr. Zhao or any of our two other executive officers were to resign or otherwise leave our employment, we might not be able
to replace them easily or at all, and our business could be disrupted and our financial condition and results of operations could be materially and adversely affected. In addition, if any member of our senior management team or any of our other key
personnel joins a competitor or forms a competing company, we may lose customers, distributors, know-how and key professionals and staff members. Although we maintain a key person life insurance policy on Dr. Zhao, we do not
maintain such insurance for any of our other employees. We may incur increased operating expenses and be required to divert the attention of other senior executives to recruit replacement for key personnel. Our industry is characterized by high
demand and intense competition for talent and the pool of qualified candidates is very limited. We cannot assure you that we will be able to retain existing, or attract and retain new, qualified personnel, including senior executives and skilled
engineers, whom we will need to achieve our strategic objectives. In addition, our ability to train and integrate new employees into our operations may not meet the growing demands of our business. The loss of any of our key personnel or our
inability to attract or retain qualified personnel, including engineers and others, could delay the development and introduction of, and would have an adverse effect on our ability to sell, our products as well as our overall business and growth
prospects.

If we are unable to effectively manage changes in our rate of growth and address related financial, operational and systems
requirements, our business and operating results could be harmed.

We have until recently experienced a period of growth and
expansion that has required us to expand our operational, engineering and financial systems, procedures and controls and to improve our information technology, accounting and other internal management systems. This effort requires substantial
managerial and financial resources, and is not yet completed. We believe that as a result of the current global economic downturn, we may encounter a period of low or even negative growth in which we will be required to carefully control
our costs and expenses in order to minimize the impact of lower revenues on our results of operations. We may be unable to achieve sufficient cost savings through these initiatives to achieve this objective. To the extent that such measures impair
or delay our new product development activities, they could adversely affect our competitiveness. Additionally, these expense control measures could adversely affect our ability to continue to make necessary improvements to our operational,
financial and management information systems. We have recently experienced significant turnover among our senior executive personnel. Our recently instituted expense reduction measures have also included headcount reductions, particularly
in our sales and marketing and general

and administrative staffs. These changes have to some extent contributed, and may in the future contribute, to the challenge of effectively managing our
changing operations. If we are unable to manage our changing rate of growth effectively, we may not be able to take advantage of market opportunities, execute our business plan or respond to competitive pressures. To successfully manage our business
in this rapidly changing environment, we believe we must effectively:



| |  |  | hire, train, integrate and manage additional qualified engineers, senior managers, sales and marketing personnel and information technology personnel;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | implement additional, and improve existing, administrative and operational systems, procedures and controls;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | expand our finance and accounting team, which includes hiring additional personnel with U.S. GAAP and internal control expertise;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | continue to expand and upgrade our design and product development capabilities; and
| | - |  | -----------------------------------------------------------------------------------



| |  |  | manage our relationships with semiconductor manufacturing service providers, customers, suppliers and other third parties.
| | - |  | --------------------------------------------------------------------------------------------------------------------------

Moreover, if our allocation of resources does not correspond with future demand for particular products, we could miss market opportunities, and our
business and financial results could be materially and adversely affected. We cannot assure you that we will be able to manage our growth effectively in the future.

Assertions by third parties of infringement by us of their intellectual property rights could disrupt our business, result in significant costs and cause our operating results to suffer.

The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights, which has resulted in protracted and
expensive litigation for many companies. We may receive claims from various industry participants alleging infringement of patents, trade secrets and/or other intellectual property rights in the future. Any lawsuit or administrative proceedings
resulting from such allegations could subject us to significant liability for damages and invalidate our existing intellectual property rights. These lawsuits, regardless of their success, would likely be time-consuming and expensive to resolve and
would divert managements time and attention. Any potential intellectual property litigation or administrative proceedings also could force us to do one or more of the following:



| |  |  | stop selling products that have used technology or manufacturing processes containing the allegedly infringing intellectual property;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | pay damages to the party claiming infringement;
| | - |  | -----------------------------------------------



| |  |  | attempt to obtain a license for the relevant intellectual property, which may not be available on commercially reasonable terms or at all; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | attempt to redesign those products that contain the allegedly infringing intellectual property with non-infringing intellectual property, which may not be possible.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------

The outcome of a dispute may result in our need to develop non-infringing technology or enter into royalty or licensing
agreements. We have agreed to defend certain of our distributors against any claims by third parties of infringement of intellectual property rights and to indemnify them for all costs and damages arising from such claims. Any intellectual property
dispute could have a material adverse effect on our business, operating results or financial condition.

We may not be able to prevent others from
unauthorized use of our intellectual property, which could harm our business and competitive position.

We design our accelerometer
and non-accelerometer products in-house and rely on a combination of patents, trademarks and employee and third-party nondisclosure agreements to protect our intellectual property.

##### Table of Contents

As of December 31, 2008, we owned seven patents and had thirteen pending patent applications in the United States, and owned two patents and had
twenty-four pending patent applications and assignment in China. As of that date, we also had one issued patent and six pending patent applications in Japan, five pending patent applications in Germany and two pending patent applications filed with
the European Patent Office. Policing any unauthorized use of our intellectual property is difficult and costly and the steps we have taken may be inadequate to prevent the misappropriation of our technology. Reverse engineering, unauthorized copying
or other misappropriation of our technologies could enable third parties to benefit from our technologies without paying us. In addition, others may independently develop similar proprietary information and techniques, gain access to our
intellectual property rights, disclose such technology or design around our patents. Additionally, we cannot assure you that any patent or registered trademark owned by us will be enforceable or will not be invalidated, circumvented or otherwise
challenged in the PRC, the United States or other countries or that the rights granted thereunder will provide competitive advantages to us or that any of our pending or future patent applications will be issued with the scope of the claims sought
by us, if at all. Furthermore, litigation may be necessary to enforce our patents and other intellectual property rights, protect our trade secrets, determine the validity of and scope of the proprietary rights of others, or defend against claims of
infringement or invalidity. Litigation could result in substantial costs and diversion of resources which could harm our business, could ultimately be unsuccessful in protecting our intellectual property rights, and may result in our intellectual
property rights being held invalid or unenforceable. Moreover, foreign intellectual property laws may not protect our intellectual property rights. Enforcement of PRC intellectual property-related laws has historically been ineffective, primarily
because of ambiguities in PRC laws and difficulties in enforcement. Accordingly, intellectual property rights and confidentiality protections in China may not be as effective as in the United States or other countries. Our failure to protect our
intellectual property effectively could harm our business, prospects and reputation.

Some of our key technologies and know-how are licensed from
third parties, including a competing company, and the termination of any of the licenses will materially and adversely affect our business.

Our business relies on our ability to use, develop and otherwise exploit our accelerometer-related technologies and know-how. Some of our key technologies and know-how were acquired by us from Analog Devices through licensing arrangements
as part of its investment in our company in 1999. All these licensing arrangements may be terminated upon the occurrence of certain events. In particular,



| |  |  | Analog Devices assigned to us its license from Canadas Simon Fraser University, or SFU, on our core thermal accelerometer technology. SFU is entitled to
terminate our license upon the occurrence of one of a number of events, including our failure to timely provide financial records. In addition, the license is terminated automatically upon the occurrence of insolvency, bankruptcy or other similar
events.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Analog Devices granted us an exclusive, perpetual license to its thermal accelerometer technology rights to use, make, have made, import, offer to sell, sell,
develop, modify, reproduce and distribute thermal accelerometer products and agreed not to use such technology rights to make or sell thermal accelerometer products itself. Analog Devices is entitled to terminate this license if our company is
dissolved or liquidated or if we breach a material provision of the license agreement.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Analog Devices granted us a non-exclusive license to certain of its testing, wafer sawing and wafer level capping and chip-level packaging technology rights to use,
make, have made, import, offer to sell, sell, develop, modify, reproduce and distribute thermal accelerometer products. Analog Devices may terminate this license if our company is dissolved or liquidated or if we breach a material provision of the
license agreement.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Under our license with SFU, SFU is entitled to continue to use the licensed technology existing at
the time of the license agreement, which was entered into in March 1999, as well as any related technology it develops thereafter without our support. Although we understand that SFU has not developed commercialized products based on its patented
accelerometer technology to date, we cannot assure you that it will not do so in the future.

##### Table of Contents

If SFU seeks to develop commercialized products based on the accelerometer technology, it may deem us as a competitor and seek to terminate or limit the
scope of our license, and as a result, our business, operations, financial condition and results of operation may be materially and adversely affected.

Our company has a significant relationship with Analog Devices. Dr. Yang Zhao, our founder and CEO, was a key member of Analog Devices MEMS division for a number of years and we received our initial funding
and technologies from Analog Devices. However, we also consider Analog Devices a significant competitor in our industry. If Analog Devices seeks to terminate, limit the scope of, or increase the fees of, any of our licenses granted or assigned by
them, our business, operations, financial condition and results of operation may be materially and adversely affected.

The loss of the services of
our independent packaging service provider could disrupt our shipments, harm our customer relationships and reduce our sales.

outsource a portion of our product packaging process to a third-party packaging service provider. As a result, we do not directly control our product delivery schedules, packaging costs or quality assurance and control for products subject to
third-party packaging process. If our packaging service provider experiences capacity constraints or disruption or financial difficulties, raises its prices, suffers any damage to its facilities, or terminates its relationship with us, and we have
insufficient capacity in-house, we may have to seek alternative packaging services which may not be available on commercially reasonable terms, or at all. Moreover, we may be exposed to risks associated with qualifying new service providers. Because
it may take us an extended amount of time to qualify third-party packaging service providers, we could experience delays in product shipments if we are required to find alternative service providers for our products on short notice. Any problems
that we may encounter with the delivery or quality of our products could damage our reputation and result in a loss of customers.

We may be unable
to obtain in a timely manner and at a reasonable cost the equipment necessary for us to remain competitive when worldwide economic growth resumes.

Our operations and expansion plans depend on our ability to obtain a significant amount of equipment from a limited number of suppliers and in a market that is characterized, from time to time, by intense demand,
limited supply and long delivery cycles. During times of significant demand for this type of equipment, lead times for delivery can be significant. Shortages of equipment could result in an increase in their prices and longer delivery times. If we
are unable to obtain equipment in a timely manner and at a reasonable cost, we may be unable to fulfill our customers orders, which could negatively impact our financial condition and results of operations.

Our expansion plans require substantial capital expenditures and are subject to a number of uncertainties, and our failure to complete these plans would have a
material adverse effect on our ability to achieve future growth.

Our future success depends on our ability to significantly
increase our manufacturing capacity and research and development capabilities.

We are engaged in constructing two new buildings adjacent
to our current facility in Wuxi, China. Upon completion, the new facility is expected to comprise 20,800 square meters, consisting of 8,700 square meters for a new research and development institute, and 12,100 square meters of new manufacturing
facilities. Construction on the new facility is expected to be completed in two phases. Phase one includes the structural construction of the two new buildings and furnishing and fitting out the office building. Phase two includes the furnishing and
equipment of the manufacturing facility. The structural construction portion of phase one is expected to be completed at the end of the second quarter of 2009. As part of our expense reduction program, we have temporarily deferred the process of
furnishing and fitting out the office building, pending more favorable economic conditions. Total capital expenditure of phase one construction is estimated to be $7.9 million, of which we have already expended $4.2 million.

There are a number of events that could delay these expansion projects or increase the costs of building
and equipping these or future facilities in accordance with our plans. These include:



| |  |  | failure to raise sufficient funds to build, and maintain adequate working capital to operate, new facilities;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | failure to timely obtain environmental and other regulatory approvals, permits or licenses;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | shortages and late delivery of building materials and manufacturing equipment;
| | - |  | ------------------------------------------------------------------------------



| |  |  | seasonal factors, such as a long and intensive wet season that limits construction; and
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | technological, capacity or other changes to our plans for new facilities necessitated by changes in market conditions.
| | - |  | ----------------------------------------------------------------------------------------------------------------------

If we are unable to establish or successfully operate additional manufacturing capacity or increase our research and development capabilities, we may be
unable to expand our business as planned. If we are unable to carry out our planned expansions, we may not be able to meet customer demand, which could result in lower profitability and a loss in market share.

We may undertake acquisitions or investments to expand our business that may pose risks to our business and dilute the ownership of our existing stockholders, and
we may not realize the anticipated benefits of these acquisitions or investments.

As part of our growth strategy, we will continue
to evaluate opportunities to acquire or invest in other businesses, intellectual property or technologies that would complement our current offerings, expand the breadth of markets we can address or enhance our technical capabilities. Acquisitions
or investments that we may potentially make in the future entail a number of risks that could materially and adversely affect our business, operating and financial results, including:



| |  |  | problems integrating the acquired operations, technologies or products into our existing business and products;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | diversion of managements time and attention from our core business;
| | - |  | --------------------------------------------------------------------



| |  |  | adverse effects on existing business relationships with customers;
| | - |  | ------------------------------------------------------------------



| |  |  | need for financial resources above our planned investment levels;
| | - |  | -----------------------------------------------------------------



| |  |  | failures in realizing anticipated synergies;
| | - |  | --------------------------------------------



| |  |  | difficulties in retaining business relationships with suppliers and customers of the acquired company;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | risks associated with entering markets in which we lack experience;
| | - |  | -------------------------------------------------------------------



| |  |  | potential loss of key employees of the acquired company;
| | - |  | --------------------------------------------------------



| |  |  | potential write-offs of acquired assets; and
| | - |  | --------------------------------------------



| |  |  | potential expenses related to the amortization of intangible assets.
| | - |  | --------------------------------------------------------------------

Our failure to address these risks may have a material adverse effect on our financial condition and results of operations. Any such acquisition or
investment may require a significant amount of capital investment, which would decrease the amount of cash available for working capital or capital expenditures. In addition, if we issue new equity securities to pay for acquisitions, our
stockholders may experience dilution. If we borrow funds to finance acquisitions, such debt instruments may contain restrictive covenants that can, among other things, restrict us from distributing dividends.

Our product liability and business disruption insurance may not be sufficient.

A significant portion of our sales derive from automotive safety applications which may expose us to significant product liability claims. We maintain
business disruption insurance and general liability insurance which includes product liability coverage in amounts we believe to be appropriate for our operations. However, we cannot assure you that this amount is sufficient to cover all potential
claims or losses and damages we may suffer. Any product liability or warranty claim, litigation, natural disaster or other forms of business disruption may result in our incurring substantial costs and in a diversion of resources.

Compliance with environmental regulations can be expensive, and noncompliance with these regulations may result in adverse publicity, potentially significant
monetary damages and fines and suspension of our business operations.

Any failure by us to control the use of, or to restrict
adequately the discharge of, hazardous substances could subject us to potentially significant monetary damages and fines or suspensions in our business operations. Our manufacturing processes generate noise, waste water, gases and other industrial
wastes and we are required to comply with Chinas national and local regulations regarding environmental protection. We believe we are currently in compliance with present environmental protection requirements and have all necessary
environmental permits to conduct our business as it is presently conducted. However, if more stringent regulations are adopted in the future, the costs of compliance with these new regulations could be substantial. If we fail to comply with any
future environmental regulations, we may be required to pay substantial fines, suspend production or cease operations.

We may need additional
capital, and the sale of additional common stock or other equity securities could result in dilution to you.

We believe that our
current cash and cash equivalents, anticipated cash flow from operations and the net proceeds from our recent initial offering will be sufficient to meet our anticipated cash needs for the near future. However, we may require additional cash
resources due to changed business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If our resources are insufficient to satisfy our cash requirements, we may seek to sell additional equity
or debt securities that may be convertible to equity securities. The sale of additional equity securities or debt securities that may be convertible to equity securities could result in dilution to you. Furthermore, the incurrence of indebtedness
would result in increased debt service obligations and could result in operating and financing covenants that would restrict our operations or our ability to pay dividends to our stockholders.

We are likely to be adversely affected by the cyclicality of the semiconductor industry.

The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, product obsolescence and price erosion,
evolving standards, short product life cycles and wide fluctuations in product supply and demand. The semiconductor industry has, from time to time, experienced significant downturns, often connected with, or in anticipation of, maturing product
cycles of both semiconductor companies and their customers products, which may occur as of, or independently from, declines in general economic conditions. These downturns have been characterized by diminished product demand, production
overcapacity, high inventory levels and accelerated erosion of average selling prices. The semiconductor industry is currently experiencing such a downturn. Prolongation or worsening of the current downturn, or the occurrence of any future downturn
may reduce our revenues and result in us having excess inventory. Furthermore, any upturn in the semiconductor industry could result in increased competition for access to limited third-party foundry, assembly and testing capacity. Failure to gain
access to foundry, assembly and testing capacity could impair our ability to secure the supply of products that we need, which could significantly delay our ability to ship our products, cause a loss of revenues and damage our customer
relationships.

The illiquidity of the auction rate securities we hold could adversely affect our financial condition, and if a
further write-down of the value of these securities were to become necessary, it would adversely affect our results of operations

As of December 31, 2008, our investments included $5.6 million of auction rate securities. Auction rate securities are generally long-term fixed income instruments that provide liquidity through a Dutch auction process that resets the
applicable interest rate at pre-determined calendar intervals, typically every 7, 28, 35 or 49 days. These investments have high credit quality ratings of at least AAA/Aaa. Due to liquidity issues that have recently been experienced in
global credit and capital markets, certain of the auction rate securities we hold have failed at auction, meaning that the amount of securities submitted for sale at auction exceeded the amount of purchase orders. If an auction fails, the issuer
becomes obligated to pay interest at penalty rates, and all of the auction rate securities we hold continue to pay interest in accordance with their stated terms. However, the failed auctions create uncertainty as to the liquidity and ultimately the
fair value of these securities. Based on our expected operating cash flows, and our other sources of cash, we do not expect the potential lack of liquidity in these investments to affect our ability to execute our current business plan in the near
term. However, the principal represented by these investments will not be accessible to us until one of the following occurs: a successful auction occurs, the issuer redeems the issue, a buyer is found outside of the auction process or the
underlying securities have matured. There can be no assurance that we would be able in the near term to liquidate these securities on favorable terms, or at all, and if we should require access to these funds sooner than we currently expect, our
inability to sell these auction rate securities could adversely affect our liquidity and our financial flexibility.

Historically, given
the liquidity created by the auction process, auction rate securities have been classified as short-term investments, included in current assets. However, due to uncertainty as to the liquidity in the near term of these securities, we have
classified the auction rate securities we held at December 31, 2008 as long-term investments. We also determined that a temporary unrealized impairment in the value of these securities existed as of December 31, 2008, and we therefore have
reduced the carrying value of these securities from $5.8 million to $5.6 million at December 31, 2008. Based on our expected cash flows and other sources of cash, we intend to hold these auction rate securities for the foreseeable future, if
necessary.

If the credit and capital markets deteriorate further, the credit ratings of the issuers or the insurers of the auction rate
securities are downgraded or the collateral underlying the securities deteriorates or other events occur that would affect the fair value of these auction rate securities, it is possible that we might conclude that some or all of them have sustained
an other-than-temporary impairment in value, such that we would be required under GAAP to further write down their carrying value. Any such write-down could result in a charge against our earnings in the period in which the impairment is recognized,
which could be material.

Risks Related to Doing Business in China

Adverse changes in economic and political policies of the PRC government or laws or regulations of the PRC could have a material adverse effect on the overall economic growth of China, which could materially and
adversely affect our business.

All of our manufacturing operations are located in China and a significant portion of devices
incorporating our products are ultimately sold to end users in China. Accordingly, our business, financial condition, results of operations and prospects are affected significantly by economic, political and legal developments in China. Chinas
economy is in transition from a planned economy to a more market-oriented economy and differs from the economies of most developed countries in many respects, including the amount of government involvement, level of development, growth rate, level
of capital reinvestment, access to financing, control of foreign exchange and allocation of resources. While the PRC economy has experienced significant growth in the past 30 years, the growth has been uneven across different regions and economic
sectors of China. The PRC government has implemented various economic and political policies and laws and regulations to encourage economic development. Although we believe that such policies have had a positive effect on the economic development of



18

##### Table of Contents

China, we cannot predict the future direction of those policies or the effects those policies may have on our business or results of operations. In addition,
since 2003, the PRC government has implemented a number of measures, such as raising surplus deposit reserve ratios and lending interest rates, in order to slow down the growth of certain sectors of Chinas economy. These actions, as well as
future actions and policies of the Chinese government, could materially affect our liquidity and access to bank financing. Furthermore, changes to the policies of the PRC government or the laws and regulations of the PRC could have a material
adverse effect on the overall economic growth of China, which could adversely affect our business.

Because our business depends in part on the
continued growth of the Chinese economy, any slowdown of such growth could have a material adverse effect on our business and operating results.

Our business is significantly dependent upon the economy and the business environment in China. In particular, we expect to continue to rely significantly on the growing demand in China for devices incorporating our
products, which in turn may be dependent on the continuing growth of the Chinese economy. The Chinese economy experienced some deflation a few years ago, and there can be no assurance that the growth of the Chinese economy will be steady or that any
slowdown of the Chinese economy will not have a material adverse effect on our business and operating results.

Chinas legal system is
characterized by uncertainty that could negatively impact our business and results of operations.

We conduct all of our
manufacturing operations at our Wuxi subsidiary, which is subject to PRC laws and regulations applicable to foreign investment in China and, in particular, laws applicable to wholly-foreign owned companies. Since 1979, PRC legislation and
regulations have significantly enhanced the protections afforded to various forms of foreign investments in China. However, China has not developed a fully integrated legal system and recently enacted laws and regulations may not sufficiently cover
all aspects of economic activities in China.

The PRC legal system is based on written statutes. The interpretation and enforcement of
these laws and regulations involve uncertainties in that (i) the laws and regulations are relatively new, (ii) only limited volumes of court decisions are published, (iii) prior court decisions may be only cited for reference but have
limited precedential value, and (iv) interpretation of statutes and regulations may also be subject to new government policies reflecting domestic political, economic or social changes. Such uncertainties may limit the legal protections
available to us.

The enforcement of existing laws, or contracts based on existing law, may be uncertain and sporadic as well. It may be
difficult to obtain swift and equitable enforcement or to obtain enforcement of a judgment by a court of another jurisdiction.

The
relative inexperience of Chinas judiciary in many types of cases creates additional uncertainty as to the outcome of any litigation. Any litigation in China may be protracted and result in substantial costs and diversion of resources and
management attention.

The PRC legal system is based in part on government policies and internal rules (some of which are not published on
a timely basis or at all) that may have a retroactive effect. As a result, we may not be aware of our violation of these policies and rules until some time after the violation.

Our activities in China may be subject to administrative review and approval by various national and local agencies of the PRC government. Because of the
changes occurring in Chinas legal and regulatory structure, we may not be able to secure the requisite governmental approval for our activities. Failure to obtain the requisite governmental approval for any of our activities could adversely
affect our business and results of operations.

The approval of the China Securities Regulatory Commission, or the CSRC, may have been required in connection with
our recent initial public offering under a recently adopted PRC regulation; failure to have obtained this approval in connection with our recent offering could have a material adverse effect on our business, operating results, reputation and trading
price of our common stock; the regulation also establishes more complex procedures for acquisitions conducted by non-PRC investors which could make it more difficult to pursue growth through acquisitions.

On August 8, 2006, six PRC regulatory agencies, namely, the PRC Ministry of Commerce, the State-owned Assets Supervision and Administration
Commission of the State Council, or SASAC, the State Administration of Taxation, the State Administration for Industry and Commerce, the CSRC and SAFE, jointly adopted the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign
Investors, or the New M&A Rule, which became effective on September 8, 2006. This New M&A Rule purports, among other things, to require offshore special purpose vehicles, or SPVs, formed for overseas listing purposes through
acquisitions of PRC domestic companies and directly or indirectly controlled by PRC companies or individuals, to obtain the approval of the CSRC prior to publicly listing their securities on a non-PRC stock exchange. On September 21, 2006, the
CSRC published a notice on its official website specifying documents and materials required to be submitted to it by SPVs seeking CSRC approval of their overseas listings. While the application of the New M&A Rule remains unclear, we
believe, based on the advice of our PRC counsel, Commerce & Finance Law Offices, that CSRC approval may not be applicable to us in the context of our recent initial public offering because we established our PRC subsidiary through direct
investment by non-PRC persons rather than by merger or acquisition of PRC domestic companies, and we did not seek CSRC approval for our initial public offering. However, as it is uncertain how the New M&A Rule will be interpreted or
implemented, we cannot assure you that the relevant PRC government agency, including the CSRC, or PRC courts would reach the same conclusion as our PRC counsel. If the CSRC or other PRC regulatory agencies determine that we should have obtained the
CSRCs approval for this offering, we may face sanctions by the CSRC or other PRC regulatory agencies. In such event, these regulatory agencies may impose fines and penalties on our operations in the PRC, limit our operating privileges in the
PRC, delay or restrict the repatriation of the proceeds from this offering into the PRC, or take other actions that could have a material adverse effect on our business, financial condition, results of operations, reputation and prospects, as well
as the trading price of our common stock.

The New M&A Rule also established additional procedures and requirements that could
make merger and acquisition activities by non-PRC investors more time-consuming and complex, including requirements in some instances that the Ministry of Commerce be notified in advance of any change-of-control transaction in which a non-PRC
investor takes control of a PRC domestic enterprise. In the future, we may grow our business in part by acquiring complementary businesses, although we do not have any plans to do so at this time. Complying with the requirements of the New M&A
Rule to complete such transactions could be time-consuming, and any required approval processes, including obtaining approval from the Ministry of Commerce, may delay or inhibit our ability to complete such transactions, which could affect our
ability to expand our business or maintain our market share.

The discontinuation of any of the preferential tax treatments currently available to us
in China could materially and adversely affect our business, financial condition and results of operations.

The PRC government or
its local agencies or bureaus provides preferential tax treatment, in the form of reduced tax rates or tax holidays, to certain qualified enterprises. Our wholly-owned PRC subsidiary in Wuxi, as a PRC high-technology company operating in a
designated high-tech development zone, benefits from a 15% preferential enterprise income tax rate, compared to a standard rate of 33%, and is exempt from enterprise income tax for two years from 2007, the year in which our Wuxi subsidiary first had
positive accumulated earnings, and is entitled to a 50% reduction in the enterprise income tax for the succeeding three years.

Moreover,
under current PRC laws and regulations, no tax is required to be withheld by our Wuxi subsidiary with respect to any dividend payments made by it to us, as its stockholder, and no PRC tax is payable by us on the dividends received from our Wuxi
subsidiary provided that such profits are permitted to be paid by it in



20

##### Table of Contents

accordance with PRC laws and regulations. In addition, as an FIE, our Wuxi subsidiary enjoys certain tax deductions for purchasing equipment made in China.
Under the relevant regulation, if an FIE purchases Chinese-made equipment, and the price does not exceed the total investment amount of such FIE, for projects that fall within certain specified categories, 40% of the purchase price amount may be
credited against the surplus between the amount of enterprise income tax payable in the current year and the amount paid in the previous year. If the credited amount is greater than the surplus, the excess amount can be carried forward for up to
five years, subject to certain exceptions. In addition, we have also benefited from rebates of value-added tax for our export products.

The discontinuation of these preferential tax treatments could materially and adversely affect our business, financial condition and results of operations. On March 16, 2007, the National Peoples Congress, the PRC legislature,
approved and promulgated a new tax law named Enterprise Income Tax Law, which took effect beginning January 1, 2008. Under the new tax law, foreign invested enterprises, or FIEs, and domestic companies are subject to a uniform
income tax rate of 25%. The new tax law provides a five-year transition period starting from its effective date for those enterprises which were established before the promulgation date of the new tax law and which were entitled to a preferential
lower income tax rate under the then effective tax laws or regulations. The income tax rate of such enterprises will gradually transition to the uniform tax rate within the transition period in accordance with implementing rules to be issued by the
State Council. For those enterprises which are enjoying tax holidays, such tax holidays may continue until their expiration in accordance with regulations to be issued by the State Council, but where the tax holiday has not yet started because of
losses, such tax holiday shall be deemed to commence from the first effective year of the new tax law. While the new tax law equalizes the income tax rates for FIEs and domestic companies, preferential tax treatment would continue to be given to
companies in certain encouraged sectors and to entities classified as high-technology companies supported by the PRC government, whether FIEs or domestic companies. According to the new tax law, entities that qualify as high-technology
companies especially supported by the PRC government will benefit from a tax rate of 15% as compared to the uniform tax rate of 25%. However, there are a number of requirements for a company to qualify as a high-technology company
especially supported by the PRC government, including those relating to business scope. There can be no assurances that our Wuxi subsidiary will qualify as a high-technology company supported by the PRC government or if it does qualify, that
it will continue to do so in the future and continue to benefit from such preferential tax rate. Following the effectiveness of the new tax law, our effective income tax rate may increase, unless we are otherwise eligible for preferential treatment.

In addition, according to the Enterprise Income Tax Law and its implementation rules, effective January 1, 2008, any dividends
payable to us by our Wuxi subsidiary will be subject to the PRC withholding tax at the rate of 10%. Currently, any such dividends are not subject to any PRC withholding tax. Although our Wuxi subsidiary has not paid any dividends to us historically,
if our Wuxi subsidiary pays any dividends to us in the future, our consolidated results of operations and the amount of dividends we pay to our stockholders may be adversely affected.

The new tax law provides only a framework of the enterprise tax provisions. Even with the promulgation of its implementation rules, the new tax law still
leaves many details on the definitions of numerous terms as well as the interpretation and specific application of various provisions unclear and unspecified.

We may be treated as a resident enterprise for PRC tax purposes after the Enterprise Income Tax Law becomes effective on January 1, 2008, which may subject us to PRC income tax for any dividends we pay to our non-PRC
stockholders.

Under the Enterprise Income Tax Law, enterprises established under the laws of non-PRC jurisdictions, but whose
de facto management body is located in the PRC are treated as resident enterprises for PRC tax purposes. Although the implementation rules of the Enterprise Income Tax Law provides a definition of de facto management body,
such definition has not been tested and there remains uncertainty as to which situations a non-PRC enterprises de facto management body is considered to be located in the PRC. Some members of our



21

##### Table of Contents

management team are currently based in the PRC, and may remain in the PRC after the effectiveness of the new tax law. If we are treated as a resident
enterprise for PRC tax purposes, we will be subject to PRC tax on our worldwide income at the 25% uniform tax rate, and any dividend payable by us to our non-PRC corporate stockholders will also be subject to a PRC withholding tax at the rate of
10%. If we are required under the new tax law to withhold income tax on dividends we pay to our non-PRC corporate stockholders, the amount of dividends we are able to pay may be materially and adversely affected.

The intercompany transactions between us and our Wuxi subsidiary may be subject to scrutiny by the United States and the PRC tax authorities, and there may be
material and adverse tax consequences if the United States or the PRC tax authorities determine that these transactions were not entered into on an arms length basis.

Our Wuxi subsidiary, Memsic Semiconductor (Wuxi) Co., Ltd., or Memsic Wuxi, is a PRC company. Our Wuxi subsidiary generally purchases manufacturing
components from third parties but purchases a small amount of manufacturing components from our U.S. headquarters at cost. We purchase all of the MEMS sensors our Wuxi subsidiary produces.

We could face material and adverse tax consequences if the United States or the PRC tax authorities determine that the transactions between us and our
Wuxi subsidiary were not entered into on an arms length basis and they may adjust our income and expenses for United States or PRC tax purposes in the form of a transfer pricing adjustment. A transfer pricing adjustment could result in a
reduction, for PRC tax purposes, of deductions recognized by our Wuxi subsidiary, or an increase, for the U.S. tax purposes, of income recognized by us on a consolidated basis, which could increase our overall tax liability and adversely affect our
results of operations.

Our Wuxi subsidiary is subject to restrictions on paying dividends or making other distributions to us.

We may rely on dividends paid by our Wuxi subsidiary for our cash needs, including the funds necessary to pay any dividends or other cash distributions
to our stockholders, service any debt we may incur and pay our operating expenses. Regulations in the PRC currently permit payment of dividends only out of accumulated profits as determined in accordance with accounting standards and regulations in
China. Our Wuxi subsidiary is required to set aside at least 10% (up to an aggregate amount equal to half of its registered capital) of its after-tax profits each year, if any, to fund certain reserve funds. These reserve funds are not distributable
as cash dividends. Memsic Wuxi currently does not have any reserve funds as of December 31, 2008 and will establish a reserve fund commencing in 2009, to the extent that it is profitable in 2009. If our Wuxi subsidiary incurs debt on its own
behalf in the future, the instruments governing the debt may restrict its ability to pay dividends or make other distributions to us. Limitations on the ability of our Wuxi subsidiary to pay dividends to us could adversely limit our ability to grow,
make investments or acquisitions that could be beneficial to our businesses, pay dividends, or otherwise fund and conduct our business. Accordingly, if for any of the above or other reasons, we do not receive dividends from our Wuxi subsidiary, our
liquidity, financial condition and ability to make dividend distribution to our stockholders will be materially and adversely affected.

Restrictions
on currency exchange may limit our ability to receive and use our revenue effectively.

The PRC government imposes controls on the
convertibility of Renminbi, or RMB, into foreign currencies and, in certain cases, the remittance of currency out of China. Because all or substantially all of our net sales are denominated in U.S. dollars, but a significant portion of our expenses
are denominated in RMB, any restrictions on currency exchange may limit our ability to use cash from sales generated in U.S. dollars to fund our business activities in China. The principal regulation governing foreign currency exchange in China is
the Foreign Currency Administration Rules (1996), as amended. Under these rules, RMB are freely convertible for trade and service-related foreign exchange transactions, but not for direct investment, loans or investment in securities



22

##### Table of Contents

outside China unless the prior approval of the State Administration of Foreign Exchange, or SAFE, is obtained. Although the PRC government regulations now
allow greater convertibility of RMB for current account transactions, significant restrictions still remain. For example, foreign exchange transactions under the capital account of our Wuxi subsidiary, including principal payments in respect of
foreign currency-denominated obligations, remain subject to significant foreign exchange controls and the approval of SAFE. These limitations could affect our ability to obtain foreign exchange for capital expenditures. The PRC government may also
at its discretion restrict access in the future to foreign currencies for current account transactions. If the foreign exchange control system prevents us from obtaining sufficient foreign currency to satisfy our currency demands, we may not be able
to pay dividends in foreign currencies to our stockholders. In addition, we cannot be certain that the PRC regulatory authorities will not impose more stringent restrictions on foreign exchange transactions in the future.

Fluctuations in the value of RMB could negatively impact our result of operations.

The value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic
conditions inside and outside of China. On July 21, 2005, the PRC government changed its policy of pegging the value of the RMB to the U.S. dollar. Under the new policy, the RMB is permitted to fluctuate within a managed band based on market
supply and demand and by reference to a basket of certain foreign currencies. This change in policy has resulted in a 17.6% appreciation of the RMB against the U.S. dollar between July 21, 2005 and December 31, 2008. While the
international reaction to the RMB revaluation has generally been positive, there remains significant international pressure on the PRC government to adopt an even more flexible currency policy. In the long term, the RMB may appreciate or depreciate
significantly in value against the U.S. dollar, depending on the fluctuation of the basket of currencies against which it is currently valued, or whether it is permitted to enter into a full float.

Our reporting currency is the U.S. dollar and all of our sales and liabilities are denominated in U.S. dollars. Approximately one third of our operating
expenses and a majority of our assets are denominated in RMB. Accordingly, as a result of Chinas 2005 currency policy, our operating expenses, in U.S. dollar equivalents, increased and our operating margins and net income were adversely
affected. In addition, the value of our assets, in U.S. dollar equivalents, decreased. To the extent that we need to convert U.S. dollars into RMB for our operations, appreciation of the RMB against the U.S. dollar would have an adverse effect on
the RMB amount we receive from the conversion. Conversely, if we decide to convert our RMB into U.S. dollars for the purpose of making payments for dividends on our common stock or for other business purposes, appreciation of the U.S. dollar against
the RMB would have a negative effect on the U.S. dollar amount available to us. As a result, any significant revaluation of the RMB may materially and adversely affect our cash flows, revenue, earnings and financial position, and the value of, and
any dividends payable on, our common stock in U.S. dollars.

Recent PRC regulations relating to offshore investment activities by PRC residents and
employee stock options granted by overseas-listed companies may increase our administrative burden, restrict our overseas and cross-border investment activity or otherwise adversely affect the implementation of our acquisition strategy. If our
stockholders who are PRC residents, or our PRC employees who are granted or exercise stock options, fail to make any required registrations or filings under such regulations, we may be unable to distribute profits and may become subject to liability
under PRC laws.

The PRC State Administration of Foreign Exchange, or SAFE, recently promulgated regulations that require PRC
residents and PRC corporate entities to register with local branches of SAFE in connection with their direct or indirect offshore investment activities. Under the SAFE regulations, PRC residents who make, or have previously made, direct or indirect
investments in offshore companies, will be required to register those investments. In addition, any PRC resident who is a direct or indirect stockholder of an offshore company is required to file or update the registration with the local branch of
SAFE, with respect to that offshore company, any material change involving its round-trip investment or capital variation, such as an increase or decrease in capital, transfer or swap of shares, merger, division, long-term equity or debt investment
or creation of any

security interest. Although our PRC counsel has advised us that these SAFE regulations are not applicable to us or our stockholders, we cannot assure you
that SAFE will agree with our position. If SAFE disagrees with us, and if any of our PRC stockholders fails to make in a timely manner the required SAFE registration or file or update the registration, our Wuxi subsidiary may be prohibited from
distributing its profits and the proceeds from any reduction in capital, share transfer or liquidation to us, and we may also be prohibited from injecting additional capital into our Wuxi subsidiary. Moreover, failure to comply with the various SAFE
registration requirements described above could result in liability under PRC laws for evasion of applicable foreign exchange restrictions.

The failure or inability of our PRC resident stockholders to comply with the registration procedures set forth therein may subject us to fines and legal sanctions. In addition, because it is uncertain how the SAFE regulations will be
interpreted or implemented, we cannot predict how these regulations will affect our business operations or future strategy. For example, we may be subject to more stringent review and approval process with respect to our foreign exchange activities,
such as remittance of dividends and foreign-currency-denominated borrowings, which may adversely affect our results of operations and financial condition. Furthermore, if we decide to acquire a PRC domestic company, we cannot assure you that we or
the owners of such company, as the case may be, will be able to obtain the necessary approvals or complete the necessary filings and registrations required by the SAFE regulations. This may restrict our ability to implement our acquisition strategy
and could adversely affect our business and prospects.

On March 28, 2007, SAFE promulgated the Application Procedure of Foreign
Exchange Administration for Domestic Individuals Participating in Employee Stock Holding Plan or Stock Option Plan of Overseas-Listed Company, or the Stock Option Rule. Under the Stock Option Rule, PRC citizens who are granted stock options by an
overseas publicly-listed company are required, through a PRC agent or PRC subsidiary of such overseas publicly-listed company, to register with SAFE and complete certain other procedures. We and our PRC employees who have been granted stock options
are subject to the Stock Option Rule as a result of our recent initial public offering. If we or our PRC optionees fail to comply with these regulations, we or our PRC optionees may be subject to fines and legal sanctions.

A number of our PRC employees exercised their stock options prior to our becoming an overseas publicly-listed company. Since there is not yet a clear
regulation on how and whether these PRC employees are required to complete their SAFE registration, and it is uncertain as to how the government authorities will interpret the Stock Option Rule, it is unclear whether such exercises are permissible
by PRC laws and it is uncertain how SAFE or other government authorities will interpret or administrate such regulations. Therefore, we cannot predict how such exercises will affect our business or operations.

PRC regulation of direct investment and loans by offshore holding companies to PRC entities may delay or limit us from using the proceeds of this offering to make
additional capital contribution or loans to our Wuxi subsidiary.

Any capital contributions or loans, that we, as an offshore
entity, make to our Wuxi subsidiary, are subject to PRC regulations. For example, any of our loans to our Wuxi subsidiary cannot exceed the difference between the total amount of investment that our Wuxi subsidiary is approved to make under relevant
PRC laws and the registered capital of our Wuxi subsidiary, and any such loans must be registered with the local branch of the SAFE as a procedural matter. In addition, our additional capital contributions to our Wuxi subsidiary must be approved by
the PRC Ministry of Commerce or its local counterpart. We cannot assure you that we will be able to obtain these approvals on a timely basis, or at all. If we fail to obtain such approvals, our ability to make equity contribution or provide loans to
our Wuxi subsidiary or to fund its operations may be adversely affected, which could harm our Wuxi subsidiarys liquidity and its ability to fund its working capital and expansion projects and meet its obligations and commitments.

We are obligated to withhold and pay PRC individual income tax on behalf of our employees who are subject to PRC
individual income tax. If we fail to withhold or pay such individual income tax in accordance with applicable PRC regulations, we may be subject to certain sanctions and other penalties and may become subject to liability under PRC laws.

Under PRC laws, we are obligated to withhold and pay individual income tax on behalf of our employees who are subject to PRC individual
income tax. In addition, the State Administration of Taxation has issued several circulars concerning employee stock options. Under these circulars, our employees working in China (which could include both PRC employees and expatriate employees
subject to PRC individual income tax) who exercise stock options will be subject to PRC individual income tax. We are obligated to file documents related to employee stock options with relevant tax authorities and withhold and pay individual income
taxes for those employees who exercise their stock options. However, the relevant tax authority has advised us that due to the difficulty in determining the fair market value of our shares as a private company, we need not withhold and pay the
individual income tax for the exercises until after the closing of this offering. Thus, we have not withheld and paid the individual income tax for the option exercises. We cannot assure you that the tax authority will not act otherwise and request
us to withhold and pay the individual income tax immediately and impose sanctions, such as fines, on us.

Any recurrence of Severe Acute Respiratory
Syndrome, or SARS, an outbreak of contagious diseases, such as avian influenza, could negatively impact our business and results of operations.

An outbreak of avian flu in the human population could result in a widespread health crisis that could adversely affect the economies and financial markets of many countries, particularly in Asia. A recurrence of SARS
in Southeast Asia could also have similar adverse effects. Since a substantial part of our operations and a substantial number of our customers and suppliers are currently based in Asia (mainly the PRC, Taiwan and Japan), an outbreak of avian flu,
SARS or other contagious diseases in Asia or elsewhere, or the perception that such outbreak could occur, and the measures taken by the governments of countries affected, including the PRC, would adversely affect our business, financial condition or
results of operations.

Risks Related to Ownership of Our Securities

The market price for our common stock may be volatile.

There has been a history of
significant volatility in the market prices of securities of technology companies. Since our initial public offering in December 2007, the market price for our common stock has ranged from a high of $11.00 to a low of $1.28 per share. The market
price of our common stock may continue to be volatile and subject to wide fluctuations, in response to factors including the following:



| |  |  | actual or anticipated fluctuations in our quarterly operating results;
| | - |  | ----------------------------------------------------------------------



| |  |  | changes in financial estimates by securities research analysts;
| | - |  | ---------------------------------------------------------------



| |  |  | conditions in the semiconductors industry;
| | - |  | ------------------------------------------



| |  |  | changes in the economic performance or market valuations of other companies in the semiconductors industry;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | announcements by us or our competitors of new products, acquisitions, strategic partnerships, joint ventures or capital commitments;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | addition or departure of key personnel;
| | - |  | ---------------------------------------



| |  |  | fluctuations of exchange rates between the RMB and the U.S. dollar;
| | - |  | -------------------------------------------------------------------



| |  |  | intellectual property litigation;
| | - |  | ---------------------------------



| |  |  | release of lock-up or other transfer restrictions on our outstanding shares or sales of additional shares; and
| | - |  | --------------------------------------------------------------------------------------------------------------

| | - |  | ---------------------------------------------------------------------------------------------------

In addition, the securities market has from time to time experienced significant price and volume fluctuations that are not related to the operating
performance of particular companies. These market fluctuations may also materially and adversely affect the market price of our shares.

If
securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding our common stock, the market price for our common stock and trading volume could decline.

The trading market for our common stock upon listing may be influenced by research or reports that industry or securities analysts publish
about us or our business. If one or more analysts who cover us downgrade our common stock, the market price for our common stock would likely decline. If one or more of these analysts cease coverage of us or fail to regularly publish reports on us,
we could lose visibility in the financial markets, which, in turn, could cause the market price for our common stock or trading volume to decline.

Delaware law and provisions of our charter documents could discourage potential acquisition proposals and could delay, deter or prevent a change in control.

Our charter documents contain provisions that could discourage, delay or prevent a change in control or changes in our management that our stockholders
may deem advantageous. These provisions:



| |  |  | require super-majority voting to amend some provisions in our amended and restated certificate of incorporation and bylaws;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | require a staggered board of directors making it more difficult for stockholders to replace a majority of our directors;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | authorize the issuance of blank check preferred stock that our board could issue to increase the number of outstanding shares and to discourage a
takeover attempt;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide that a special meeting of stockholders may be called only by the president, the chief executive officer or the board of directors acting pursuant to a
resolution adopted by the board; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | establish advance notice requirements for nominations for election to our board by stockholders at stockholder meetings.
| | - |  | ------------------------------------------------------------------------------------------------------------------------

In addition, we are subject to Section 203 of the Delaware General Corporation Law, which, subject to some exceptions, prohibits business
combinations between a Delaware corporation and an interested stockholder, which is generally defined as a stockholder who becomes a beneficial owner of 15% or more of a Delaware corporations voting stock for a three-year
period following the date that the stockholder became an interested stockholder. Section 203 could have the effect of delaying, deferring or preventing a change in control that our stockholders might consider to be in their best interests.

These anti-takeover defenses could discourage, delay or prevent a transaction involving a change in control. These provisions could also
discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choice and cause us to take corporate actions with which you may disagree.

Our corporate actions are substantially controlled by our principal stockholders and affiliated entities.

As of March 27, 2009, individuals and entities whom we consider to be our affiliates beneficially owned approximately 33.8% of our outstanding shares of common stock. These included Dr. Yang Zhao, our
president and chief executive officer, who beneficially owned 7.8% of our outstanding shares of common stock. These



26

##### Table of Contents

stockholders, if acting together, could exert substantial influence over matters such as electing directors and approving material mergers, acquisitions or
other business combination transactions. This concentration of ownership may also discourage, delay or prevent a change in control of our company, which could deprive our stockholders of an opportunity to receive a premium for their shares as part
of a sale of our company and might reduce the price of our shares. These actions may be taken even if they are opposed by our other stockholders, including those who purchase shares in this offering. In cases where their interests are aligned and
they vote together, these stockholders will also have the power to prevent or cause a change in control. In addition, these persons could divert business opportunities from us to themselves or others.

Failure to achieve and maintain effective internal controls in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on
our business.

As a public company, we are required to document and test our internal financial control procedures in order to
satisfy the requirements of Section 404 of the Sarbanes-Oxley Act, which requires annual management assessments of the effectiveness of our internal controls over financial reporting and will require, beginning with the 2009 audit period, a
report by our independent auditors that both addresses managements assessments and provides for the independent auditors assessment of the effectiveness of our internal controls. During the course of our testing, we may identify
deficiencies which we may not be able to remediate in time to meet our deadline for compliance with Section 404, and we may also identify inaccuracies or deficiencies in our financial reporting that could require revisions to or restatement of
prior period results. Testing and maintaining internal controls will also involve significant costs and can divert our managements attention from other matters that are important to our business. We may not be able to conclude on an ongoing
basis that we have effective internal controls over financial reporting in accordance with Section 404, and our independent auditors may not be able or willing to issue a favorable assessment of our conclusions. Failure to achieve and maintain
an effective internal control environment could harm our operating results, could cause us to fail to meet our reporting obligations and could require that we restate our financial statements for prior periods, any of which could cause investors to
lose confidence in our reported financial information and cause a decline, which could be material, in the trading price of our common stock.

It may
be difficult to enforce judgments against us in U.S. courts.

Although we are a Delaware corporation, our manufacturing subsidiary
and approximately 38.6% of our assets were located outside of the United States as of December 31, 2008. As a result, you may not be able to enforce against us in U.S. courts judgments based on the civil liability provisions of U.S. federal
securities laws. It is unclear if original actions of civil liabilities based solely upon U.S. federal securities laws are enforceable in courts outside the United States. It is equally unclear if judgments entered by U.S. courts based on the civil
liability provisions of U.S. federal securities laws are enforceable in courts outside the United States. Any enforcement action in a court outside the United States will be subject to compliance with procedural requirements under applicable local
law, including the condition that the judgment does not violate the public policy of the applicable jurisdiction.



|Item 2. | Properties.
|------- | -----------

Our corporate
headquarters are located at One Tech Drive, Suite 325, Andover, Massachusetts 01810. In addition, we also have an office in Chicago, Illinois. Our Andover headquarter is responsible for sales and marketing, financing, and research and development,
while the Chicago office is also responsible for research and development. In addition, we have sales offices in Shanghai and Shenzhen, China; Taipei, Taiwan; and Tokyo, Japan. We lease these premises from unrelated third parties. The lease contract
on our corporate headquarters in Andover expires in June 2013.

Our current manufacturing facility and our new facility under construction
are located on a parcel of land of approximately 35,000 square meters in Wuxi, Jiangsu Province of China. We purchased the land use rights to the

##### Table of Contents

land in 2003. Our current manufacturing facility is housed in a building that comprises a production area of approximately 3,400 square meters and an office
area of approximately 1,300 square meters. The current facility is responsible for manufacturing, product engineering, manufacturing engineering, quality assurance, packaging and testing as well as application engineering.

In addition, we have begun construction of two new buildings adjacent to our current facility since December 2007. Upon completion, the new facility is
expected to comprise 20,800 square meters, consisting of 8,700 square meters for a new research and development institute, and 12,100 square meters of new manufacturing facilities. Construction on the new facility is expected to be completed in two
phases. Phase one includes the structural construction of the two new buildings and furnishing and fitting out the office building. Phase two includes the furnishing and equipment of the manufacturing facility. The structural construction portion of
phase one is expected to be completed at the end of the second quarter of 2009. As part of our expense reduction program, we have temporarily deferred the process of furnishing and fitting out the office building, pending more favorable economic
conditions. Total capital expenditure of phase one construction is estimated to be $7.9 million, of which we have already expended $4.2 million.



|Item 3. | Legal Proceedings.
|------- | ------------------

We are not
involved in any litigation or other legal matters which, if decided adversely against us, could reasonably be expected to have a material adverse impact on our business or operations. However, many participants in our industry have significant
intellectual property rights and have demonstrated a willingness to instigate litigation based on allegations of infringement. We cannot assure you that we will not receive notices of intellectual property right infringements in the future.

On March 27, 2009, the last reported sale price on the Nasdaq Global Market for our common
stock was $2.00 per share. On March 27, 2009, there were approximately 37 holders of record of our common stock. This number does not include stockholders for whom our shares were held in nominee or street name.

We currently intend to retain future earnings, if any, to finance our growth. We do not anticipate paying cash dividends on our common
stock in the foreseeable future. Payment of future dividends, if any, will be at the discretion of our board of directors after taking into account various factors, including our financial condition, operating results, current and anticipated cash
needs, restrictions in financing agreements and plans for expansion.

The net proceeds to us of our initial public offering in 2007,
including the net proceeds from exercise of the underwriters over-allotment option to purchase common stock, were approximately $60.2 million. Through December 31, 2008, we have applied approximately $2.2 million of the net proceeds to
fund capital expenditures for the expansion of our manufacturing facility in Wuxi and $4.2 million to the construction of two new buildings adjacent to that facility. We invested the balance of $53.8 million of the net proceeds from our initial
public offering in money market funds and auction rate securities, pending other uses.

In May 2008, we issued 95,000 shares of our common
stock, as partial payment of the purchase price of certain assets and technology related to industrial gas-flow meters, in a private placement exempt from registration under Section 4(2) of the Securities Act.

Issuer Purchases of Equity Securities

In
November 2008, our Board of Directors authorized a stock repurchase program, under which our management is authorized to repurchase up to $5 million of our common stock. Under the program, share purchases may be made from time to
time in the open market or through privately negotiated transactions depending on market conditions, share price, trading volume and other factors. Such purchases, if any, will be made in accordance with applicable insider trading and other
securities laws and regulations. These repurchases may be commenced or suspended at any time or from time to time without prior notice. We repurchased 106,300 shares of our common stock for a total amount of $182,494 during the three months ended
December 31, 2008, pursuant to this repurchase program as follows:

|Item 7. | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

Overview

We provide advanced semiconductor sensor and
system solutions based on integrated MEMS technology and mixed signal circuit design. Our accelerometer products are used to measure tilt, shock, vibration and acceleration, and have a wide range of applications such as mobile phones, automotive
safety systems and video projectors. We combine proprietary thermal-based MEMS technology and advanced analog mixed signal processing circuitry design into a single chip using a standard CMOS process. This approach allows us to provide sensor
solutions at a lower cost, with higher performance and greater functionality than our competitors. In addition, our technology platform allows us to easily integrate additional functions or create new sensors to expand into magnetic, touch and flow
sensors and related applications.

Although we have experienced significant growth since our products were first commercialized in 2001,
our growth has slowed recently. The recent increases in our unit sales volume and sales revenue were primarily attributable to increases in the sale of our products for mobile phone applications and automotive applications. In 2008, however, our net
sales and gross margins have been adversely affected by a number of factors, including a slowdown in the mobile handset market in China, the May 2008 earthquake in China, and generally weak global economic conditions. The U.S. and other global
economies are currently experiencing a recession that has affected all sectors of the economy and that has continued to deepen, resulting in declines in economic growth and consumer confidence, increases in unemployment rates and uncertainty about
economic stability. Global credit and financial markets have also experiencing extreme disruptions, including diminished liquidity and credit availability and rapid fluctuations in market valuations. Our business has been affected by these
conditions and is likely to be affected by them in the future, and there is no certainty that economic conditions will not deteriorate further. These uncertainties affect businesses such as ours in a number of ways, making it difficult to accurately
forecast and plan our future business activities. Deteriorating economic conditions may lead consumers and businesses to continue to postpone spending, which may cause our customers to cancel, decrease or delay their existing and future orders with
us. In addition, the inability of customers to obtain credit could negatively affect our revenues and our ability to collect receivables. In addition, financial difficulties experienced by our suppliers or distributors could result in product
delays, increased accounts receivable defaults and inventory challenges.

We expect that sales of our accelerometer products to continue to
represent a predominant share of our revenue for the foreseeable future. We expect that sales of our first non-accelerometer products, including magnetic sensors and gas-flow sensors, will begin to increase in the second half of 2009.

We sell our products either to distributors, which then resell to OEMs and ODMs, or to OEM and ODM customers directly. Historically, a small number of
our customers have accounted for a substantial portion of our revenue, and sales to our largest distributor customers and OEM and ODM customers have varied significantly. This significant variation is in part due to the fact that our sales are made
on the basis of purchase orders rather than long-term contracts. Although our distributors generally provide us with non-binding rolling forecasts, our distributors generally have up to 30 days prior to delivery to cancel or reschedule shipments
pursuant to our distribution agreements. This arrangement has added to the fluctuation and unpredictability of our sales. Because our products are a component of our customers products, our sales performance is significantly affected by the
sales performance of our customers products. It is difficult for us to accurately forecast our product demand because in the case where we sell our products to distributors, we may not know the identity of the distributors OEM and ODM
customers and information regarding their demand.

OEM and ODM customers products are complex and require significant time to define,
design and ramp to volume production. Our sales cycle begins with our marketing and sales staff and application engineers engaging with our OEM and ODM customers system designers and management, which is typically a multi-month, or even
multi-year, process. If such process is successful, an OEM and ODM customer will decide to incorporate our solution in its product, which we refer to as a design-win. Because the sales cycles for our products are long,

##### Table of Contents

we incur expenses to develop and sell our products, regardless of whether we achieve the design-win and well in advance of generating revenue, if any, from
those expenditures. Although we do not have long-term purchase commitments from any of our distributor customers or OEM and ODM customers, once one of our products is incorporated into an OEMs or ODMs design, it is likely to remain a
part of the design for the life cycle of its product. We believe this to be the case because a redesign would generally be time consuming and expensive. We have experienced revenue growth due to an increase in the number of our products offered, an
expansion of our customer base, an increase in the number of design-wins within any one OEM and ODM customer and an increase in the average revenue per design-win.

We manufacture our products utilizing a semi-fabless model by outsourcing the production of CMOS wafers and completing the post-CMOS MEMS process in-house. By outsourcing the standard CMOS manufacturing
process, we are able to more efficiently manage our capital expenditures and cost of goods sold.

Description of Certain Line Items

Net Sales

Net sales represent gross revenue
net of an allowance for the estimated amount of product returns and sales rebates from our customers. Sales to distributors are made pursuant to distributor agreements, which allow for the return of goods under certain circumstances. We recognize
revenue in accordance with Staff Accounting Bulletin No. 104 and Statement of Financial Accounting Standards No. 48, or SFAS 48. Prior to August 30, 2007, we deferred recognition of sales to a major distributor, World Peace Industrial
Co., Ltd., or WPI, which did not meet the criteria of SFAS 48, until the product was sold through to WPIs OEM and ODM customers. On August 30, 2007, we amended the distributor agreement with WPI to allow returns only upon our approval.
Accordingly, the criteria under SFAS No. 48 have been met for this distributor as of August 30, 2007, and we have recognized revenue upon shipment to WPI for all shipments subsequent to this date. For all shipments to WPI made prior to
August 30, 2007, we continued to recognize our revenue upon shipments to its OEM and ODM customers.

Historically, our revenue has
been derived primarily from shipments of our accelerometer products. The primary factors that affect our revenue are the sales volumes and average selling prices of our products. Prior to 2008, the significant increases in our net sales have been
primarily attributable to the increases in the sales volumes of our products, particularly those for mobile phone and automotive applications. The average selling prices of our products generally decline over time and are primarily affected by a
combination of the following factors:



| |  |  | the semiconductor market is highly competitive, and as a result, the average selling prices of particular products generally experience rapid declines over the
course of their respective product and technology life cycles. We seek to mitigate the impact of this trend on our business by continuing to rapidly design, develop and sell new generations of products with additional functionalities to replace
older generation products;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may also reduce our product prices as we are able to increase our production yields or to reduce our manufacturing costs, particularly the wafer prices;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in our product mix may affect the average selling prices of our products. Historically, for example, our revenue derived from consumer and mobile phone
markets, as a percentage of our total revenue, has increased. Our products for these markets generally have lower average selling prices than products for the automotive market. The average selling prices of products may continue to be affected by
our strategy to increase market adoption of our products in certain markets; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we occasionally grant discounts to our largest customers or OEM and ODM customers for high volume purchases.

Net Sales by Application

In 2008,
net sales from mobile phone applications were the largest component of our total sales, representing 37.9% of total net sales. Although our reliance on sales from mobile phone applications decreased in



31

##### Table of Contents

2008, we expect that net sales from mobile phone applications will continue to be the largest component of our total sales in 2009. We attribute much of the
decrease in net sales from mobile phone applications in 2008 to a general slowdown of the mobile phone market in China and the weak global economy in general.

Net sales from automotive applications, in absolute terms, have increased in 2008, primarily due to increases in sales of rollover application products to Autoliv Inc. To increase net sales from the automotive market,
we are currently seeking to increase sales from other automotive applications and to expand our customer base. However, revenue increases, if any, from the automotive market will require significant time, as the development lead time in this market
is generally longer than other markets to date, and this market has been disproportionately affected by the current global downturn.

Net
sales from consumer applications have fluctuated historically as a result of the generally short life cycle of consumer electronics and changes in our customer base. As our product offering and customer base for consumer applications continue to
diversify, we expect net sales from consumer applications to fluctuate less. Net sales from industrial and other markets have been limited, and we do not expect revenue from these markets to contribute significantly to our total revenue in 2009.

The following table sets forth our net sales by application for the periods indicated by amount and as a percentage of our net sales
(dollar amounts in thousands).

Net Sales by Customer Base

Our customers primarily consist of distributors, OEMs and ODMs. Historically, a small number of our customers have accounted for a substantial portion of
our net sales. We expect that significant customer concentration will continue for the foreseeable future. Our customers representing 10% or more of our net sales accounted for approximately 78.8% and 71.6%, respectively, of our net sales in 2008
and 2007.

We have experienced and will continue to experience fluctuations in demand from a significant number of customers, including
many of our largest customers. It is difficult for us to accurately forecast our product demand, particularly in the case of sales to our distributors, as we may not know the identity of the distributors OEM and ODM customers and lack
information regarding their demand.

Occasionally, design changes in the products of our OEM and ODM customers have resulted in the loss of
sales. For example, a design change in a product of a large OEM customer in 2008 for mobile phone applications resulted in a decrease of our sales to such customer in 2008. That customer accounted for 44.6% of our net sales in 2007.

Net Sales by Geography

Our products
are shipped to OEM and ODM customers worldwide. However, we focus on different application markets among geographical regions. In the greater China region, our revenue has historically been



32



---

##### Table of Contents

primarily derived from products for mobile phone applications. We are also seeking to expand the consumer and industrial applications markets in the greater
China region. In Japan, our revenue has primarily been derived from products for consumer applications, particularly projectors. We are also seeking to penetrate the automotive market in Japan. In North America, our revenue has primarily been
derived from products for automotive applications. In Europe, our revenue has fluctuated. In 2008, we experienced a revenue increase from products for automotive applications in Europe.

The following table sets forth our net sales by geographical region for the periods indicated by amount and as a percentage of our net sales (dollar
amounts in thousands).

Cost of Goods Sold

We are a semi-fabless company. We outsource wafer production to third-party foundries and complete the post-CMOS MEMS and most of the packaging, assembly and testing functions in-house. We also purchase our ceramic
packaging materials from third-party suppliers. Cost of goods sold consists of: (i) cost of wafer, ceramic and other materials purchased from third parties; (ii) manufacturing overhead, primarily consisting of salaries and wages of our
quality control employees and manufacturing-related management employees, depreciation, and equipment and parts; (iii) direct labor, primarily consisting of salaries and wages of our manufacturing operators; and (iv) outsourced processing
fees paid to third-party packaging service providers.

Our relationships with third-party foundry and packaging service providers do not
provide for guaranteed levels of production capacity at pre-determined prices. As a result, our outsourcing costs relating to wafer production, and to a lesser extent, packaging services, are susceptible to changes based on conditions in the global
semiconductor market and our service providers available capacity.

Prior to August 30, 2007 we deferred recognition of cost of
goods sold for a major distributor, WPI, which did not meet the criteria of SFAS 48, until the product was sold through to WPIs OEM and ODM customers. WPI accounted for 34.6% of our revenue in 2006, 55.3% of our revenue in 2007 and 12.4% of
our revenue in 2008. On August 30, 2007, we amended the distributor agreement with WPI to allow for returns only upon our approval. Accordingly, the criteria under SFAS No. 48 have been met for this distributor as of August 30, 2007, and
subsequent to that date we have recognized the cost of goods sold as the related products are sold. For all shipments to WPI made prior to August 30, 2007, we continued to recognize costs related to products once sold by WPI to its OEM and ODM
customers.

Gross Profit and Gross Margin

Until recently, our gross profit generally experienced growth in line with increases in our revenue. However, more recently, our gross margin has been decreasing from 67.0% in 2006, to 65.1% in 2007 and 47.9% in 2008.
Our gross profit and gross margin are affected by a variety of factors, including average selling prices of our products, our product application mix, prices of wafers, excess and obsolete inventory, pricing by competitors, changes in production
yields, and percentage of sales conducted through distributors. Our products for mobile



33

##### Table of Contents

phone applications, which are sold to distributor customers, have historically had lower margins than our products for automotive products, which are sold
directly to our OEM and ODM customers, and this trend has accelerated recently. The increase in the percentage of our net sales in products for mobile phone applications in recent years has therefore had an adverse effect on our overall gross
margin. Notwithstanding the relatively lower margin in the mobile phone applications market, we expect to derive an increasing percentage of our total net sales from that market because of the significant potential for further revenue growth from
increased penetration in that market. Our gross margin in 2008 was adversely affected by the costs related to the Olympic torch project for which during the second quarter, we had to reverse revenue that was previously recognized in the first
quarter. Excluding the impact of the torch project, our gross margin in 2008 would be 53.8%.

Research and Development Expenses

Research and development expenses are recognized as they are incurred and primarily consist of salaries and wages of research and development
employees; research costs, primarily consisting of mask costs and prototype wafers, consulting fees paid for outside design services; travel and other expenses; and beginning in 2006, stock-based compensation under SFAS 123(R) attributable to our
research and development employees.

Historically, research and development expenses have increased both in absolute terms and as a
percentage of total net sales. We expect this trend to continue for the foreseeable future as we seek to diversify into non-accelerometer products and hire additional employees in connection with the new research and development institute that we
established in the second quarter of 2007.

General and Administrative Expenses

General and administrative expenses primarily consist of salaries and wages for administrative personnel; costs for professional services, including
legal, tax and accounting services; depreciation and amortization expenses for non-manufacturing equipment; travel and entertainment expenses; office supply and other office-related expenses; office rental expenses; others, such as utilities,
insurance and provision for accounts receivable; and stock-based compensation under SFAS 123(R). We expect that our general and administrative expenses will increase as we hire additional personnel and incur costs related to the anticipated growth
of our business and our operations as a public company upon the completion of this offering. However, we expect that such expenses will decrease as a percentage of net sales.

Sales and Marketing Expenses

Sales and marketing expenses primarily consist of wages,
salaries and commissions for our sales and marketing personnel; consulting expenses, primarily consisting of sales consulting services and software application consulting services; travel expenses; independent sales representatives commissions;
office rental; market promotion and others expenses and stock-based compensation under SFAS 123(R) We expect sales and marketing expenses to continue to increase as we hire additional sales and marketing personnel, expand our sales and marketing
network and engage in additional marketing and promotional activities. However, we expect that such expenses will decrease as a percentage of net sales.

Other Income (Expense)

Other income (expense), primarily consists of interest income earned on our cash and
cash equivalents, and interest expense incurred on our borrowings and net foreign currency exchange gains and losses.

Provision (Benefit) for Income
Taxes

We conduct sales through our headquarters in Andover, Massachusetts. Our Wuxi subsidiary is primarily engaged in
manufacturing and engineering activities and does not conduct direct sales to customers. For internal



34



---

##### Table of Contents

accounting and PRC tax purposes, we account for the transfers of goods from our Wuxi subsidiary to our U.S. headquarters as sales, and calculate the transfer
price of such sales based on a markup of manufacturing and operating costs. We believe the prices of these sales were consistent with the prevailing market prices.

U.S. Tax

In the United States, we are subject to the federal income tax and the Massachusetts state
income tax, which are approximately at the rates of 34% and 9.5%, respectively. At December 31, 2008, the Company had gross U.S. net operating loss carryforwards of $1.4 million, which expire in the year 2028. Included within this amount is
approximately $258,000 of excess tax deductions associated with non-qualified stock options that have been exercised. When these excess tax benefits actually result in a reduction to currently payable income taxes, the tax benefit will be
recorded as an increase to additional paid-in capital. The Companys operating losses may be subject to limitations under provisions of the Internal Revenue Code.

PRC tax

Our PRC taxes primarily consist of enterprise income tax, value-added tax, and certain other
miscellaneous taxes. As of December 31, 2008, our Wuxi subsidiary had no PRC NOL carryforwards available to offset future PRC enterprise income tax and entered into the second year of the two year tax exemption period. In 2008, we recorded
deferred tax assets in China as a result of temporary differences between the pre-tax income and taxable income for our MEMSIC Semiconductor since we ended the last year of the two-year tax exemption period in 2008 and will enter into a three-year
period at 50% reduced income tax rate beginning in 2009.

Enterprise Income Tax

PRC enterprise income tax is calculated based on taxable income determined under PRC accounting principles. In accordance with Income Tax of China
for Enterprises with Foreign Investment and Foreign Enterprises, or the Foreign Enterprise Income Tax Law, and the related implementing rules, foreign investment enterprises, or FIEs, incorporated in the PRC are generally subject to an
enterprise income tax rate of 33%.

The Foreign Enterprise Income Tax Law and the related implementing rules provide certain favorable tax
treatments to FIEs which qualify as high-technology companies and are registered and operate in designated high-technology zones in the PRC. Our Wuxi subsidiary is a high-technology FIE registered and operating in a designated high-technology zone.
Accordingly, under the Foreign Enterprise Income Tax Law, its implementing rules and several local regulations, our Wuxi subsidiary is entitled to a preferential enterprise income tax rate of 15%. In addition, our Wuxi subsidiary is entitled to a
five-year tax holiday, pursuant to which it is exempted from paying the enterprise income tax for 2007, the year in which it first had positive accumulated earnings, and 2008. After the two-year exemption period, our Wuxi subsidiary will be entitled
to a 50% reduction from the then applicable income tax rate for each year from 2009 through 2011. After the expiration of this five-year tax holiday period, a preferential enterprise income tax rate of 15% may apply for so long as our Wuxi
subsidiary continues to be recognized as a high-technology company especially supported by the PRC government.

To qualify as a
high-technology company especially supported by the PRC government for PRC enterprise income tax purposes, a business entity generally must meet certain financial and non-financial criteria, including, but not limited to:



| |  |  | products or services of the business falling under the scope of high-technology especially supported by the PRC government;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | a minimum level of revenue generated from high-technology related sales or services as a percentage of total revenue;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | a minimum number of employees engaged in research and development as a percentage of total number of employees; and
| | - |  | -------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | a minimum level of research and development expenses as a percentage of total revenue.
| | - |  | --------------------------------------------------------------------------------------

If the PRC central government or applicable local governments determine that our Wuxi subsidiary is not or no longer qualifies as a high-technology
company especially supported by the PRC government, our effective enterprise income tax rate would increase as a result.

In
addition, as an FIE, our Wuxi subsidiary enjoys certain tax deductions for purchasing equipment made in China. Under the relevant regulation, if an FIE purchases Chinese-made equipment, and the price does not exceed the total investment amount of
the FIE, for projects that fall within certain specified categories, 40% of the purchase price amount may be credited against the surplus between the amount of enterprise income tax payable in the current year and the amount paid in the previous
year. If the credited amount is greater than the surplus, the excess amount can be carried forward for up to five years, subject to certain exceptions.

If our Wuxi subsidiary ceases to qualify for its current preferential enterprise income tax rates, we will consider options that may be available at the time that would enable it to qualify for other preferential tax
treatment. To the extent we are unable to offset the expiration of, or the inability to obtain, preferential tax treatment with new tax exemptions, tax incentives or other tax benefits, our effective tax rate will increase. The amount of income tax
payable by our Wuxi subsidiary in the future will depend on various factors, including, among other things, the results of operations and taxable income of our Wuxi subsidiary (which is in turn partially dependent on our internal transfer pricing
policies) and the applicable statutory tax rate.

On March 16, 2007, the National Peoples Congress approved and promulgated a
new tax law named Enterprise Income Tax Law, which took effect beginning January 1, 2008. Under the new tax law, FIEs and domestic companies are subject to a uniform tax rate of 25%. The new tax law provides a five-year transition
period starting from its effective date for those enterprises which were established before the promulgation date of the new tax law and which were entitled to a preferential lower tax rate under the then effective tax laws or regulations. In
accordance with regulations issued by the State Council, the tax rate of such enterprises may gradually transition to the uniform tax rate within the transition period. For those enterprises which are enjoying tax holidays, such tax holidays may
continue until their expiration in accordance with the regulations issued by the State Council. While the new tax law equalizes the tax rates for FIEs and domestic companies, preferential tax treatment would continue to be given to companies in
certain encouraged sectors and to entities classified as high-technology companies especially supported by the PRC government, whether FIEs or domestic companies.

Our Wuxi subsidiary has been qualified as a high-technology company especially supported by the PRC government. Therefore, a preferential
enterprise income tax rate of 15% under the new tax law may apply to our Wuxi subsidiary. However, according to the relevant transition preferential tax policies issued by the State Council, the preferential enterprise income tax rate under the new
tax law and the transition-period preferential tax policy cannot apply simultaneously. That is to say, our Wuxi subsidiary may either choose to enjoy the exemption from enterprise income tax for 2007 and 2008 and a 50% reduction on the uniform
enterprise income tax rate of 25% from 2009 to 2011, or, choose the preferential enterprise income tax rate of 15% for qualified high-technology companies under the new tax law. We believe the adoption of the transition-period preferential tax
policy will be more beneficial to our Wuxi subsidiary. Therefore, from 2009 to 2011, the effective income tax rate for our Wuxi subsidiary will be 12.5%.

As a result of the new tax law, following the year 2011, upon expiration of our 50% reduction from the then applicable income tax rate, our effective tax rate may increase, unless we are otherwise eligible for
preferential treatment.

See Risk FactorsRisks Related to Doing Business in ChinaThe discontinuation of any of the
preferential tax treatments currently available to us in China could materially and adversely affect our business, financial condition and results of operations.

Other PRC taxes

Other miscellaneous PRC taxes primarily consist of property tax, land-use tax and stamp tax which are accounted for in our general and administrative expenses, and education surcharge, which is recorded as part of our
cost of goods sold.

Critical Accounting Policies

The preparation of our consolidated financial statements and related notes requires us to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, net sales and expenses, and
related disclosure of contingent assets and liabilities. We have based our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making
judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Our management has discussed the development, selection and disclosure of these estimates with our board of directors. Actual results may
differ from these estimates under different assumptions or conditions.

An accounting policy is considered to be critical if it requires an
accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably
likely to occur periodically, could materially impact the consolidated financial statements. We believe that the following critical accounting policies are the most sensitive and are those that require the more significant estimates and assumptions
used in the preparation of our consolidated financial statements. You should read the following descriptions of critical accounting policies, judgments and estimates in conjunction with our consolidated financial statements and other disclosures

We account for our investments under SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities (SFAS 115). Marketable securities are classified as available-for-sale securities and are
accounted for at their fair value. Unrealized gains and losses on these securities are reported as other comprehensive income (loss), respectively. Under SFAS 115, unrealized holding gains and losses are excluded from earnings and reported net of
the related tax effect in other comprehensive income as a separate component of shareholders equity. When the fair value of an investment declines below its original cost, we evaluate the investment in accordance with Financial Accounting
Standards Board (FASB) Staff Positions 115-1 and 124-1, The Meaning of Other-Than-Temporary Impairment and Its Applications to Certain Investments, which address the determination as to when an investment is considered impaired, whether that
impairment is other than temporary, and the measurement of an impairment loss. When the fair value of an investment declines below its original cost, we consider all available evidence to evaluate whether the decline is other-than-temporary. Among
other things, we consider the duration and extent of the decline and economic factors influencing the markets. If a decline in fair value is judged to be other-than-temporary, the cost basis of the individual security is written off to fair value as
a new cost basis and the amount of the write-down is reflected in earnings (that is, accounted for as a realized loss). The new cost basis is not to be changed for subsequent recoveries in fair value. Subsequent increases in the fair value of
available-for-sale securities are included in other comprehensive income; subsequent decreases in fair value, if not an other-than-temporary impairment, also are included in other comprehensive income. The determination of whether a loss is other
than temporary is highly judgmental and may have a material impact on our results of operations.

As of December 31, 2008, our
investments included $5.6 million of auction rate securities. Due to liquidity issues that have recently been experienced in global credit and capital markets, certain of the auction rate securities we hold have failed at auction, meaning
that the amount of securities submitted for sale at auction exceeded the amount of purchase orders. If an auction fails, the issuer becomes obligated to pay interest at

penalty rates, and all of the auction rate securities we hold continue to pay interest in accordance with their stated terms. We have classified our
auction rate securities as long-term investments at December 31, 2008, due to our assessment of the uncertainty as to the time frame within which we would likely be able to liquidate these investments under current market conditions.

We estimated the fair value of these securities at December 31, 2008 using broker valuations and internally-developed models of
the expected future cash flows related to the securities. One of the more significant assumptions made in our internally-developed models was the term of expected cash flows of the underlying auction rate securities. We developed several scenarios
for the liquidation of the auction rate securities over periods that ranged from 3 to 5 years. Based on our internal modeling and the value provided by the broker, we concluded that our auction rate securities had incurred a temporary
unrealized impairment loss in the amount of $247,000 as of December 31, 2008, and we reduced the carrying amount of these investments by this amount to be $5.6 million. In estimating the fair value of these investments, we considered the
financial condition and near-term prospect of the issuers, the magnitude of the losses compared to the investments cost, the length of time the investments have been in an unrealized loss position, the probability that we will be unable to
collect all amounts due according to the contractual terms of the security, whether the security has been downgraded by a rating agency, and our ability and intent to hold these investments until the anticipated recovery in market value occurs. This
unrealized loss has been recorded as a component of other comprehensive income in the accompanying financial statements. We intend to hold these auction rate securities for the foreseeable future, if necessary.

Revenue Recognition

We recognize revenue from
the sale of our products to OEM and ODM customers when all of the following conditions have been met: (i) evidence exists of an arrangement with the customer, typically consisting of a purchase order or contract; (ii) our products have
been shipped and risk of loss has passed to the customer; (iii) we have completed all of the necessary terms of the purchase order or contract; (iv) the amount of revenue to which we are entitled is fixed or determinable; and (v) we
believe it is probable that we will be able to collect the amount due from the customer. To the extent that one or more of these conditions has not been satisfied, we defer recognition of revenue. An allowance for estimated future product returns
and sales price allowances is established at the date of revenue recognition. An allowance for uncollectible receivables is established by a charge to operations, when in our opinion, it is probable that the amount due to us will not be collected.
Historically, product returns and bad debt expense have not been significant.

Our products are warranted against manufacturing defects for
twelve months following the date of sale (eighteen months following date of sale to a distributor). Products returned under the provisions of the warranty agreement require our pre-approval. Our sole obligation under the provisions of the
warranty agreement is to replace or repair the product. Reserves for potential warranty claims are provided at the time of revenue recognition and are based on several factors including historical claims experience, current sales levels and our
estimate of repair costs. To date, warranty expenses have not been significant.

Sales to distributors are made pursuant to distributor
agreements, which allow for the return of goods under certain circumstances. We follow the provision of SFAS No. 48 Revenue Recognition When Right of Return Exists. SFAS No. 48 includes the following criteria for recognition of
sales to distributors: (i) the selling price to the distributors is fixed or determinable at the date of shipment; (ii) our product has been shipped and risk of loss has passed to the distributors; (iv) it is probable that the amount
due from the distributor will be collected; (v) we do not have a significant future obligations to directly assist in the distributors resale of the product and (vi) the amount of future returns can be reasonably estimated. Once
these criteria are met, we recognize revenue upon shipment to the distributor and estimate returns based on historical sales returns.

WPI
was a significant distributor which accounted for 55.3% of our net sales in 2007 and 12.4% of our net sales in 2008. The criteria under SFAS No. 48 were not met for WPI for the periods prior to August 30, 2007. Based on the early stage of
our relationship with WPI and its size, we were unable to make a reasonable estimate



38

##### Table of Contents

of future returns. Therefore, we deferred recognition of revenue and related costs of good sold associated with WPI until the relevant products were shipped
by WPI to its OEM and ODM customers for those periods.

On August 30, 2007, we amended the distributor agreement with WPI to allow for
returns only upon our approval. Accordingly, the criteria under SFAS No. 48 have been met for this distributor as of August 30, 2007, and we have recognized revenue and related costs upon shipment to this distributor for all shipments
subsequent to this date. For all shipments to WPI made prior to August 30, 2007, we continued to recognize our revenue and related costs upon shipments to its OEM and ODM customers.

Allowance for Doubtful Accounts

The following table sets forth activities in our allowance
for doubtful accounts for the periods indicated:

Our standard policy on payment terms is net 30 days from delivery. In 2008 and 2007, our average
days sales outstanding was 62 days and 61 days, respectively. At certain times our trade accounts receivable have included balances from customers that have exceeded 10% of total accounts receivable. We have established credit limits for each of our
customers and reviewed such limits prior to product shipment. We believe that such customers are of high credit quality and that we are not subject to unusual risk with respect to such customers.

Allowance for doubtful accounts receivable is included as a charge to sales and marketing expense. We evaluate the sufficiency of our allowance for
accounts receivable on a quarterly basis.

The sufficiency of our allowance for uncollectible accounts receivable is evaluated based on the
recoverability of our accounts receivable, which is in turn based on a combination of factors, many of which are based on estimates. These factors include indicators of a specific customers inability to meet its financial obligations to us,
such as in the case of bankruptcy filings or deterioration in the customers operating results or financial position. In addition, we may consider the length of time the receivables are past due, the financial health of the customer and
historical experience. If circumstances related to specific customers change, our estimates of the recoverability of receivables could be further adjusted.

Inventories

Inventories are stated at the lower of cost (weighted average first in-first out) or market. We evaluate
our inventory for potential excess and obsolete inventories based on forecasted demands and record a provision for such amounts as necessary. We recorded a provision of $108,000 and $0 in 2008 and 2007, respectively.

Stock-Based Compensation

General

Statement of Financial Accounting Standards No. 123(R), or SFAS 123(R), Share-Based Payment, addresses accounting for stock-based compensation
arrangements, including stock options and shares issued to directors, officers and employees under various stock-based compensation arrangements. This statement requires that companies use the fair value method, rather than the intrinsic-value
method, to determine compensation expense for all stock-based arrangements. Under the fair value method, stock-based compensation expense is determined at the measurement date, which is generally the date of grant, as the aggregate amount by which
the



39

##### Table of Contents

estimated future value of the equity security at the expected date of acquisition as computed under a stock valuation model exceeds the exercise price to be
paid. The resulting compensation expense, if any, is recognized for financial reporting over the term of vesting or performance. This statement was first effective for us on January 1, 2006. As permitted, we have elected to use the prospective
application as our transition method, under which SFAS 123(R) applies to all prospective stock option and share grants of stock-based compensation awards and to grants prior to January 1, 2006 that have been modified subsequently.

Stock-based compensation arrangements with non-employees are accounted for utilizing the fair value method or, if a more reliable measurement, the
value of the services or consideration received. The resulting compensation expense, if any, is recognized for financial reporting over the term of performance or vesting.

Description of 2000 Omnibus Stock Plan

On March 29, 2000, our stockholders and board of
directors approved the 2000 Omnibus Stock Plan, as amended, or 2000 Stock Plan, under which 2,969,000 shares of our common stock was reserved for issuance to directors, officers, employees, and consultants. Options granted under the 2000 Stock Plan
may be incentive stock options, nonqualified stock options and/or restricted stock. The 2000 Stock Plan provides that the exercise price of incentive stock options must be at least equal to the market value of our common stock at the date such
option is granted. For incentive stock option grants to an employee who owns more than 10% of the outstanding shares of our common stock, the exercise price on the incentive stock option must be 110% of market value at the time of grant. Granted
options expire in ten years or less from the date of grant and vest based on the terms of the awards, generally ratably over four years.

Prior to our initial public offering in December 2007, there was no public market for our common stock. Accordingly, the board of directors determined the market value of the common stock at the date of grant by considering a number of
relevant factors including our operating and financial performance and corporate milestones achieved, the prices at which shares of convertible preferred stock in arms length transactions were sold, the composition of and changes to the
management team, the superior rights and preferences of securities senior to the common stock at the time of each grant and the likelihood of achieving a liquidity event for the shares of common stock underlying stock options.

Determination of Fair Value of Common Stock

The
following table sets forth for all stock options we granted during 2007 the number of shares subject to the option, the exercise price, the fair value of our common stock on the date of grant and the fair value of the option:

|(1) | We granted 389,000 common stock options with an exercise price of $4.88 per share in July 2007 and 457,950 common stock options with an exercise price of $6.50 per share in August
2007. At the time of the grants, the exercise price was determined by our board of directors with input from management based on the estimated fair value of our common stock. Subsequently, we had retrospective valuation reports prepared by a third
party specialist to support the fair value of the options granted and determined the fair value to be $6.84 for the options granted in July and $7.64 for the options granted in August. As a result of the valuation reports, the grants were modified
to increase their respective exercise prices to the reported fair values.

At the time of these option grants, the exercise
price was determined by the board with input by management based on the various objective and subjective factors mentioned above as well as valuation reports when available. The intrinsic value per share is being recognized as compensation expense
over the applicable vesting period (which corresponds to the service period).

##### Table of Contents

We engaged an independent third party to assist management in preparing retrospective valuation reports
to support the fair value of options granted. We believe that the valuation methodologies used in the retrospective valuations are consistent with the Practice Aid of the American Institute of Certified Public Accountants entitled Valuation of
Privately Held Company Equity Securities Issued as Compensation.

In each retrospective valuation, a weighted average of the guideline
public company method, the guideline transaction method and the discounted future cash flow method was used to estimate the enterprise value of the Company at the applicable valuation date. The guideline public company method and the guideline
transaction method estimate the fair value of a company by applying to that company market multiples, in this case revenue and/or EBITDA multiples, of firms in similar lines of business. The companies used for comparison under the guideline public
company method and guideline transaction method were selected based on a number of factors, including but not limited to, the similarity of their industry, business model, financial risk and other factors to those of MEMSIC. The discounted future
cash flow method involves applying appropriate risk-adjusted discount rates between 18% to 25% to estimated debt-free cash flows, based on forecasted revenues and costs. The projections used in connection with this valuation were based on our
expected operating performance over the forecast period. There is inherent uncertainty in these estimates; if different discount rates or assumptions had been used, the valuation would have been different.

We allocated value to the common stockholders using the probability-weighted expected return method. Under the probability-weighted expected return
method, the fair value of the common stock is estimated based upon an analysis of future values for us assuming various future outcomes, the timing of which is based on the plans of our board and management. Share value is based on the
probability-weighted present value of expected future investment returns, considering each of the possible outcomes available as well as the rights of each share class.

Four scenarios were considered. Three of the scenarios assume a stockholder exit, either through an initial public offering, or IPO, a sale of MEMSIC to a strategic acquirer, or dissolution of the company at or below
liquidation preference. The fourth scenario assumes operations continue as a private company and no exit transaction occurs. For the IPO scenario, the estimated future and present values for our common stock were calculated using assumptions
including; the expected pre-money valuation based on the guideline public company method discussed above; the expected dates of the future expected IPO; and an appropriate risk-adjusted discount rate. For the sale scenario, the estimated future and
present values for our common stock were calculated using assumptions including: the expected dates of the future expected sale and an appropriate risk-adjusted discount rate. For the dissolution scenario, all of the proceeds are distributed to the
preferred stockholders. No proceeds are available for distribution to the common stockholders, and the value of the common stock is zero. For the private company with no exit scenario, an equal weighting of the guideline public company method and
the discounted cash flow method based on present day assumptions was used. Finally, the present value calculated for our common stock under each scenario was probability weighted based on managements estimate of the relative occurrence of each
scenario.

For additional information regarding our estimates of fair value of our common stock during 2007, see our Annual Report on Form
10-K for the year ended December 31, 2007, under the heading Managements Discussion and Analysis of Financial Condition and Results of OperationsCritical Accounting PoliciesStock Based Compensation.

Income Taxes

Our deferred tax assets and
liabilities reflect the future tax consequences of temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and of tax credits. Deferred tax assets arise when a
companys financial statements recognize charges or expenses that, for income tax purposes, will not be allowed as deductions until future periods. For example, when a corporation incurs an expense in its financial statements, such as
restructuring charges, that it is not allowed to deduct on its



41

##### Table of Contents

federal tax return until paid in the future, the future tax benefit of that expense is generally recorded in the income statement as a reduction of income
tax expense and in the balance sheet as a deferred tax asset. The same general treatment applies to the carry forward of unused net operating losses and unused tax credits. Deferred tax assets are often netted with deferred tax liabilities when
presented in the balance sheet and are referred to as net deferred tax assets. We measure our deferred tax assets and liabilities using the tax rates and laws we expect to be in effect at the time of their reversal or utilization.

Under SFAS No. 109, Accounting for Income Taxes, a net deferred tax asset may be carried on the balance sheet at its full value
only if it is more likely than not that the deductions, losses, or credits giving rise to such deferred tax asset will be used in the future. We periodically evaluate our deferred tax assets for recoverability using a consistent approach that
considers the relative impact of negative and positive evidence, including our historical profitability and projections of future taxable income. Under GAAP, we are required to establish a valuation allowance for deferred tax assets and record a
charge to income or stockholders equity if we determine, based on available evidence at the time the determination is made, that it is not more likely than not that the deferred tax assets will be realized. In evaluating the need for a
valuation allowance, we estimate future taxable income based on management-approved business plans and ongoing tax planning strategies. This process involves significant management judgment about assumptions that are subject to change from period to
period based on changes in tax laws or variances between our projected operating performance, our actual results and other factors.

As of
December 31, 2008, we had been in a three year cumulative loss position in the United States for financial statement reporting purposes. Under SFAS No. 109, this cumulative loss position constitutes significant, objective evidence that we
may not be able to realize our deferred tax assets in the future. Further, economic conditions in our markets deteriorated and pricing pressures increased during the fourth quarter of 2008, resulting in a net loss for the quarter and for the full
year.

After considering these factors and the other available evidence, we were unable to conclude that as of December 31, 2008 it
was more likely than not that we would generate sufficient taxable income in the United States in the foreseeable future to realize our deferred tax assets. We therefore recorded a non-cash charge of $1.3 million during the fourth quarter to
establish a full valuation allowance against our deferred tax assets in the United States in 2008. The $115,000 balance of our net deferred tax asset at December 31, 2008 related to PRC taxes applicable to our China subsidiary. In the event we
generate future taxable income in the future, our income tax expense in future periods could be reduced to the extent those deferred tax assets are deemed recoverable.

We reinvest any earnings of our Wuxi subsidiary, MEMSIC Semiconductor, in its operations. We have not provided for U.S. income taxes that could result from the distribution of such earnings to us. If these earnings
were ultimately distributed to the U.S. in the form of dividends or otherwise, or if the shares of the Wuxi subsidiary were sold or transferred, we would be subject to additional U.S. income taxes, net of impact of any available foreign tax credits.
It is not practicable to estimate the amount of unrecognized deferred U.S. taxes on these undistributed earnings.

On January 1, 2007,
we adopted FIN 48. At the adoption date, we had no unrecognized tax benefits and determined that the impact of FIN 48 was not material to our consolidated financial statements.

Year Ended December 31, 2008 Compared to Year Ended December 31, 2007

Net Sales. Our net sales decreased by 20.6% to $20.1 million in 2008 from $25.3 million in 2007. This decrease was due to a decrease in the number
of units sold, primarily for mobile phone applications, which was partly offset by an increase in unit sales for automotive applications, and to reductions in the average selling price of our products, particularly in the mobile phone and consumer
market in China. Sales in mobile phone applications accounted for $7.6 million in net sales in 2008, compared to $14.4 million in net sales in 2007. Sales in automotive rollover applications accounted for $5.6 million in 2008, compared to $4.9
million in net sales in 2007.

Cost of goods sold.Our cost of goods sold increased by 19.3% to $10.5 million in 2008 from $8.8
million in 2007. This increase was primarily due to the decrease in the volume of units sold and the costs related to the Olympic torch project.

Gross profit and gross margin.Our gross profit decreased by 41.8% to $9.6 million in 2008 from $16.5 million in 2007. Our gross margin decreased to 47.9% in 2008 from 65.1% in 2007 primarily due to the continuing decline in
the average selling prices of our products, particularly on products for mobile phone

applications, less efficient absorption of our manufacturing overhead cost as a result of the reduced production volume, and the impact of costs related to
our Olympic torch project for which during the second quarter, we had to reverse revenue that was previously recognized in the first quarter. Excluding the impact of the torch project, our gross margin in 2008 would be 53.8%.

Research and development. Our research and development expenses increased by approximately 29.7%, to $4.4 million in 2008 from $3.4 million
in 2007. This increase is primarily due to (i) an increase of $0.3 million in wages and salaries as a result of an increase in our head count for engineers and other research and development employees in both China and the U.S. (ii) an
increase of $0.6 million in research costs relating to the development of new products and (iii) an increase of $0.1million in our engineers travel expense. Research and development expenses, as a percentage of total net sales, increased
to 21.8% for the year ended December 31, 2008 from 13.3% for the year ended December 31, 2007 due largely to the decreased revenues. We will continue to invest in research and development projects to develop new products and system
solutions, and as a result, we expect our research and development expense will continue to increase in 2009.

Sales and
marketing. Our sales and marketing expenses increased by approximately 9.2% to $3.2 million in 2008 from $2.9 million in 2007. The increase was primarily due to (i) an increase of $0.6 million in wages and salaries due to an
increase in the number of sales and marketing employees and (ii) an increase of $0.1 million in stock based compensation expense, offset by (iii) a decrease of $0.4 million consulting fees for third-party sales consulting and sales-related
software application services. Sales and marketing expenses, as a percentage of total net sales, increased to 15.7% for the year ended December 31, 2008 from 11.5% for the year ended December 31, 2007. We expect our sales and marketing
expense will decrease in the first quarter of 2009 as a result of headcount reduction in our sales and marketing department at the end of 2008.

General and administrative. Our general and administrative expenses increased by approximately 53.0% to $5.9 million in 2008 from $3.9 million in 2007. This increase was primarily due to (i) an increase of $0.1 million in wages
and salaries due to an increase in the number of general and administrative employees, (ii) an increase of $0.7 million in professional fees as a result of our becoming a public company, (iii) an increase of $0.5 million in stock-based
compensation expense, (iv) an increase of $0.4 million in director and officer insurance and franchise taxes and (v) an increase of $0.3 million in travel, transportation and office related expenses. General and administrative expenses, as
a percentage of total net sales, increased to 29.6% for the year ended December 31, 2008 from 15.4% for the year ended December 31, 2007. As part of our expense reduction program, we reduced our general and administrative headcounts at the
end of 2008 and we will continue to control discretionary general and administrative expenses going into 2009.

Other income.Our
other income was $2.5 million in 2008 compared to an expense of $0.7 million in 2007, primarily reflecting interest income on our higher cash and investment balances.

Provision (benefit) for income taxes.Our income tax provision was $0.3 million in 2008 compared to an income tax provision of $1.0 million in 2007. Our income tax provision in 2008 reflected our establishment
of a full valuation allowance of $1.3 million at December 31, 2008 against our U.S. deferred tax assets due to uncertainty regarding future taxable income in the United States. Our Wuxi subsidiary recorded a tax benefit of $0.1 million related to
establishing a deferred tax asset in China. Our Wuxi subsidiary will start its three-year tax holiday period, at 50% of the unified tax rate of 25%, in 2009.

Liquidity and Capital Resources

As of December 31, 2008, our investments included $5.6 million of auction rate
securities that have failed at auction and that are classified as long-term investments on our balance sheet. The principal represented by these investments will not be accessible to us until one of the following occurs: a successful auction occurs,
the issuer redeems the issue, a buyer is found outside of the auction process or the underlying securities have matured. Based on our expected operating cash flows, and our other sources of cash, we do not expect the potential lack of liquidity in
these investments to affect our ability to execute our current business plan in the near term. There can

##### Table of Contents

be no assurance that we would be able in the near term to liquidate these securities on favorable terms, or at all, and if we should require access to these
funds sooner than we currently expect, our inability to sell these auction rate securities could adversely affect our liquidity and our financial flexibility.

We outsource certain steps of the manufacturing process to third parties while conducting the remaining steps in-house. As a result, our principal uses of cash historically have consisted of both payments to our
suppliers for the costs related to the outsourcing of wafer fabrication and outsourced processing fees paid to and materials purchased from third parties, as well as payments for our manufacturing overhead and equipment purchases. Other significant
cash outlays primarily consist of salaries, wages and commissions for our non-manufacturing related employees. As of December 31, 2008, our principal sources of liquidity consisted of cash, cash equivalents and short-term investments of $65.9
million.

We believe that our current cash and cash flow from operations will be sufficient to meet our anticipated cash needs, including
working capital requirements and capital expenditures for at least the next twelve months. Our future cash requirements will depend on many factors, including our operating income, the timing of our new product introductions, the costs to
maintaining adequate manufacturing capacity, the continuing market acceptance of our products, or other changing business conditions and future developments, including any investments or acquisitions we may decide to pursue. If our existing cash is
insufficient to meet our requirements, we may seek to sell additional equity securities, debt securities or borrow from banks. We cannot assure you that financing will be available in the amounts we need or on terms acceptable to us, if at all. The
sale of additional equity securities, including convertible debt securities, would be dilutive to our stockholders. The incurrence of indebtedness would divert cash for working capital requirements and capital expenditures to service debt and could
result in operating and financial covenants that restrict our operations and our ability to pay dividends to our stockholders. If we are unable to obtain additional equity or debt financing, our business, operations and prospects may suffer.

The following table sets forth a summary of our cash flows for the periods indicated (in thousands):

In November 2008, our board of directors authorized a $5.0 million stock repurchase program and in
the fourth quarter of 2008, we repurchased 106,300 shares at an average price of $1.72 per share. Approximately $4.8 million remains in our share repurchase program.

Operating Activities

Net cash provided by operating activities for 2008 was $4.1 million,
which was derived from a net loss of 1.7 million adjusted to reflect a net increase relating to non-cash items and a net decrease relating to changes in balances of operating assets and liabilities. The adjustments relating to non-cash items, a
net of $3.4 million, were primarily due to depreciation and amortization expense of $1.7 million, stock based compensation expense of $1.3 million, and deferred income taxes of $0.4 million. The adjustments relating to changes in balances of
operating assets and liabilities, a net of $2.4 million, primarily consisted of $4.0 million decrease in account receivables, due to lower sales and successful collection efforts, particularly with respect to collections from one large distributor,
and $0.2 million decrease in other assets, primarily due to a decrease in prepaid expenses, both

##### Table of Contents

offset by $1.6 million decrease in accounts payable and accrued expenses primarily related to payment of initial public offering expenses and $0.2 million
increase in inventories, primarily due to inventory planning decisions made earlier in 2008, before the impact of the current economic downturn was fully apparent.

Net cash provided by operating activities for 2007 was $3.3 million, which was derived from a net income of $6.1 million adjusted to reflect a net increase relating to non-cash items and a net decrease relating to
changes in balances of operating assets and liabilities. The adjustments relating to non-cash items, a net of $2.5 million, were primarily due to depreciation and amortization expense of $1.0 million, stock based compensation expense of $0.7
million, and deferred income tax of $0.9 million. The adjustments relating to changes in balances of operating assets and liabilities, a net of $5.3 million, consisted of a $2.1 million increase in accounts payable and accrued expenses primarily
attributable to increased manufacturing materials payables and to initial public offering expenses; a $1.1 million decrease in deferred revenue, due to the amendment of WPIs distributor agreement; a $3.1 million increase in account
receivables, primarily due to an increase in sales; a $2.2 million increase in inventories, primarily due to an increase in sales forecast; and a $1.0 million increase in other assets, primarily due to an increase in refundable income taxes in the
U.S. and investment interest receivables.

Investing Activities

Net cash provided by investing activities for 2008 was $33.3 million, primarily due to proceeds from the sale of short-term investments, offset by a $6.4 million investment in the construction of our new facilities
and expansion of our existing manufacturing equipment capacity.

Net cash used in investing activities for 2007 was $44.4 million,
primarily due to (i) the purchase of short-term investments and (ii) the purchase of property and equipment for expanding our manufacturing capacity.

Financing Activities

Net cash provided by financing activities for 2008 was $6.5 million, primarily due to $7.6
million in net proceeds from the exercise by the underwriters in our initial public offering of their over-allotment option.

Net cash
provided by financing activities for 2007 was $54.4 million, primarily due to $52.6 million in net proceeds from our initial public offering.

Capital
Expenditures

We have begun construction of two new buildings adjacent to our current facility since December 2007. Upon completion, the
new facility is expected to comprise 20,800 square meters, consisting of 8,700 square meters for a new research and development institute, and 12,100 square meters of new manufacturing facilities. Construction on the new facility is expected to be
completed in two phases. Phase one includes the structural construction of the two new buildings and furnishing and fitting out the office building. Phase two includes the furnishing and equipment of the manufacturing facility. The structural
construction portion of phase one is expected to be completed at the end of the second quarter of 2009. As part of our expense reduction program, we have temporarily deferred the process of furnishing and fitting out the office building, pending
more favorable economic conditions. Total capital expenditures in connection with phase one construction is estimated to be $7.9 million, of which we have already expended $4.2 million. Phase two of our new facility is pending the completion of
phase one construction. Upon completion of phase two, we expect to have in place manufacturing capacity to meet our future production requirements for both accelerometer products and non-accelerometer products.

Our capital expenditures amounted to $6.4 million and $4.6 million in 2008 and 2007, respectively.

Operating lease commitments represent the leases we entered into for our headquarters, sales
offices and certain equipment. Non-cancelable purchase orders included primarily contractual commitments we placed with the new facility construction contractors.

In addition, we are under a contractual obligation to make royalty payments to Simon Fraser University on a license relating to our core thermal accelerometer technology. These royalty payments are calculated as a
percentage of net sales subject to a maximum of $100,000 per year.

Recent Accounting Pronouncements

In April 2008, the FASB issued FASB Staff Position (FSP) 142-3, Determination of the Useful Life of Intangible Assets, which amends the factors
that must be considered in developing renewal or extension assumptions used to determine the useful life over which to amortize the cost of a recognized intangible asset under SFAS No. 142. The FSP is effective for financial statements for
fiscal years beginning after December 15, 2008. The Company is currently evaluating the impact that the adoption of this FSP will have on our consolidated financial statements.

In December 2007, the FASB issued FAS 141R, Business Combinations,or SFAS 141R. This statement is to improve the relevance, representational
faithfulness, and comparability of the information that a reporting entity provides in its financial reports about a business combination and its effects. This statement is effective prospectively to business combinations for which the acquisition
date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. We are currently evaluating the impact that the adoption of SFAS 141R may have on our 2009 consolidated financial statements.

In February 2007, the FASB issued SFAS No. 159. The Fair Value Option for Financial Assets and Financial Liabilities, including an
amendment of FASB Statement No. 115. SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been
elected will be recognized in earnings at each subsequent reporting date. This statement is effective for financial statements issued for fiscal years beginning after November 15, 2007. SFAS 159 will be effective for us on January 1, 2008.
The adoption of the provisions of SFAS 159 did not have any impact on our financial position or results of operations.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders of Memsic, Inc.

We
have audited the accompanying consolidated balance sheets of Memsic, Inc. as of December 31, 2008 and December 31, 2007, and the related consolidated statements of operations, convertible preferred stock and stockholders equity
(deficit), and cash flows for each of the two years in the period ended December 31, 2008. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits 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. We were not engaged to perform an audit of the Companys
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, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position
of Memsic, Inc. at December 31, 2008 and December 31, 2007, and the consolidated results of their operations and their cash flows for each of the two years in the period ended December 31, 2008, in conformity with U.S. generally
accepted accounting principles.

As discussed in Note 4 to the consolidated financial statements, effective January 1, 2008, the Company
adopted Statement of Financial Accounting Standards No. 157, Fair Value Measurements. As discussed in Note 13 to the consolidated financial statements, effective January 1, 2007, the Company adopted Financial Accounting Standards Board
Interpretation No. 48,Accounting for Uncertainty in Income Taxes.

Notes to Consolidated Financial Statements

1. NATURE OF THE BUSINESS AND OPERATIONS

MEMSIC, Inc (the Company) was incorporated on March 3, 1999 as a Delaware corporation. The Company is a leading provider of
semiconductor sensor systems solutions based on micro electromechanical systems (MEMS) technology and advanced integrated circuit design. The Company has integrated a MEMS technology-based inertial sensor, commonly known as an accelerometer, with
mixed signal processing circuitry onto a single chip using a standard complementary metal-oxide-semiconductor (CMOS) process. This proprietary technology has allowed for sensor solutions at lower cost, higher performance and improved functionality.
Utilizing a standard CMOS process allows easily integrated additional functions, the creation of new sensors to expand into magnetic, touch and flow sensors, as well as other MEMS application areas beyond accelerometers. Any application that
requires the control or measurement of motion is a potential application for accelerometers. Accelerometer products have a wide range of applications for consumer electronics, mobile phones, automotive (airbags, rollover detection, electronic
stability control and navigation systems), as well as business, industrial and medical applications.

MEMSIC, Inc. maintains its corporate
headquarters in Massachusetts. All manufacturing operations are provided by its wholly-owned subsidiary, MEMSIC Semiconductor (Wuxi) Company Limited (MEMSIC Semiconductor), located in the Peoples Republic of China (PRC).

2. BASIS OF PRESENTATION

The consolidated financial
statements include the accounts of MEMSIC, Inc. and MEMSIC Semiconductor. MEMSIC Semiconductor was organized in November 1999 in Wuxi, Jiangsu Province, in the PRC. All significant intercompany balances and transactions have been eliminated in
consolidation.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Advertising Costs

Advertising costs are expensed as incurred and are included in sales and marketing expenses.
Advertising costs were not material for the periods presented in the accompanying consolidated statements of operations.

Cash Equivalents

The Company considers all highly liquid instruments with an original maturity of three months or less to be cash equivalents. The Company
places its cash equivalents with high credit quality financial institutions that participate in the U.S. Treasurys Temporary Guarantee Program, which protects market investment balances as of September 19, 2008 through April 30,
2009.

Foreign Currency

The
Companys manufacturing operations and certain other operations are conducted by MEMSIC Semiconductor. The functional currency of MEMSIC Semiconductor is the Renminbi. Financial transactions between the Company and MEMSIC Semiconductor are
conducted in United States dollars. At December 31, 2008 and 2007, the underlying currency for approximately 38.6% and 19.6% of consolidated assets, respectively, was the Renminbi. The Company does not believe that it is subject to significant
foreign exchange risk and, accordingly, has not utilized hedging strategies with respect to such foreign exchange exposure.

Comprehensive Income (Loss)

Statement of Financial Accounting Standards (SFAS) No.130, Reporting Comprehensive Income, established the standards for reporting and displaying comprehensive income (loss) in financial statements.
Comprehensive income (loss) is defined to include all changes in stockholders equity (deficit) during the period other than those changes that result from investments by and distributions to stockholders.

Concentration of Credit

Financial instruments
that potentially subject the Company to significant concentration of credit risk consist primarily of cash and cash equivalents as well as accounts receivable. The Companys cash and cash equivalents are on deposit at financial institutions
and, at times, exceed the federal insured limits. The Company believes that the financial institutions are of high credit quality and that the Company is not subject to unusual credit risk beyond the normal credit risk associated with commercial
banking relationships.

The Company as indicated below had customers that comprise more than 10% of sales or accounts receivables for all
periods presented in the accompanying consolidated financial statements. The Company establishes credit limits for each of its customers and reviews such limits prior to product shipment. The Company believes that the customers indicated below are
of high credit quality and that the Company is not subject to unusual risk with respect to such customers, and generally does not require collateral. The following schedule summarizes the percent of total sales to customers for the periods
indicated.

Concentration of Supplier

The Company relies on one supplier who is an affiliated investor for all wafer purchases required in the manufacturing process for its accelerometer
products, which represents approximately 50% of all material costs for all periods presented in the accompanying consolidated financial statements. At December 31, 2008, the Company had $45,000 of non-cancellable open purchase order agreements
with this affiliated supplier.

##### Table of Contents

Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires the Company to make estimates and assumptions that affect at the date of the financial statements the
reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses. Actual results could differ from these estimates.

Fair Value of Financial Instruments

The
carrying amounts of the Companys financial instruments, which include cash equivalents, short-term investments, accounts receivable, accounts payable, notes payable and accrued expenses approximate their fair values due to the short term
nature of the instruments.

Income Taxes

Deferred tax assets and liabilities relate to temporary differences between the financial reporting bases and the tax bases of assets and liabilities, the carryforward tax losses and available tax credits. Such assets and liabilities are
measured using tax rates and laws expected to be in effect at the time of their reversal or utilization. Valuation allowances are established, when necessary, to reduce the net deferred tax asset to an amount more likely than not to be realized.

Intangible Assets

Intangible
assets relate to issued and applied for patents on the Companys core technology, as well as gas meter processing know-how purchased in May 2008. The Company amortizes its own patents over 15 years and amortizes the purchased know-how over 5
years.

Intangible assets consisted of the following:

Amortization expense expected over the next five years is approximately $144,000 per year.

Inventories

Inventories are
stated at the lower of cost (weighted average FIFO) or market. The Company evaluates its inventory for potential excess and obsolete inventories based on forecasted demands and records a provision for such amounts as necessary. The Company recorded
a provision of $108,000 and $0 in 2008 and 2007, respectively.

Net Income (Loss) per Common Share

Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted-average common shares outstanding. Diluted net income (loss)
per share is calculated by dividing net income (loss) by the weighted-average common shares and potentially dilutive securities outstanding during the period using the treasury stock method.

##### Table of Contents

As of December 19, 2007, the effective date of the Companys IPO, the Company transitioned from
having two classes of equity securities outstanding, common and preferred stock, to a single class of common stock. For the period prior to December 19, 2007, the Company calculated net income (loss) per share in accordance with SFAS
No. 128, Earnings Per Share as clarified by Emerging Issues Task Force (EITF) Issue No. 03-6, Participating Securities and the Two-Class Method Under FASB Statement No. 128, Earnings Per Share. EITF No. 03-6
clarifies the use of the two-class method of calculating earnings per share as originally prescribed in SFAS No. 128. Under the two-class method, basic net income (loss) per share is computed by dividing the net income (loss)
available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the more dilutive of the (a) the two-class method, or (b) the
if-converted method. The Company allocates net income first to convertible preferred stockholders based on dividend participation rights under the Companys Certificate of Incorporation and then to convertible preferred and common stockholders
based on ownership interests. Net losses are not allocated to convertible preferred stockholders.

Property and Equipment

Property and equipment are recorded at cost. For financial reporting, depreciation is provided utilizing straight-line and accelerated methods over the
estimated three to five-year life for equipment and furniture and fixtures, estimated twenty year life for the building in China, and the estimated forty-seven year life for land in China. Chinese statutory regulations stipulate that the ownership
of land reverts back to the PRC after forty-seven years. The Company estimates a residual value of 10% of the assets original cost in calculating depreciation for assets in China. Leasehold improvements are depreciated over the shorter of the
useful life or term of the lease. Costs for repairs and maintenance that do not increase the useful life of the asset are expensed as incurred.

Research and Development

Research and development costs are expensed as incurred.

Revenue Recognition

The Company recognizes
revenue from the sale of its product to end customers when all of the following conditions have been met: (i) evidence exists of an arrangement with the customer, typically consisting of a purchase order or contract; (ii) the
Companys products have been shipped and risk of loss has passed to the customer; (iii) the Company has completed all of the necessary terms of the purchase order or contract; (iv) the amount of revenue to which the Company is
entitled is fixed or determinable; and (v) the Company believes it is probable that it will be able to collect the amount due from the customer. To the extent that one or more of these conditions has not been satisfied, the Company defers
recognition of revenue. An allowance for estimated future product returns and sales price allowances is established at the date of revenue recognition. An allowance for uncollectible receivables is established by a charge to operations when in the
opinion of the Company, it is probable that the amount due to the Company will not be collected.

The Company sells its products to end
customers as well as distributors. Sales to distributors are made pursuant to distributor agreements, which allow for the return of goods under certain circumstances. Accordingly, the Company follows the provisions of SFAS No. 48,
Revenue Recognition When Right of Return Exists. SFAS No. 48 includes the following criteria for recognition of sales to distributors: (i) the selling price to the distributor is fixed or determinable at the date of
shipment; (ii) the distributors obligation to pay the selling price is not contingent on resale of the product; (iii) the Companys product has been shipped and risk of loss has passed to the distributor; (iv) it is
probable that the amount due from the distributor will be collected; (v) the Company does not have significant future obligations to directly assist in the distributors resale of the product; and (vi) the amount of future returns can
be reasonably estimated. Once these criteria are met, the Company recognizes revenue upon shipment to the distributor and estimates returns based on historical sales returns.

##### Table of Contents

The Company had a significant distributor for which the criteria under SFAS No. 48 had not been met
for periods prior to August 30, 2007. Based on the early stage of the relationship with this distributor and its size, the Company was unable to make a reasonable estimate of future returns. Therefore, the Company deferred recognition of
revenue and related product costs associated with sales to this distributor until the product was shipped to the distributors end customers. Deferred revenue at June 30, 2007 amounted to $2.0 million. On August 30, 2007, the Company
amended the agreement with the distributor to allow for returns only upon the Companys approval. Accordingly, the criteria under SFAS No. 48 have been met for this distributor as of August 30, 2007, and the Company recognizes revenue
upon shipment to this distributor for all shipments made on or after August 30, 2007 based on shipments to this distributor. For all shipments through this distributor made prior to August 30, 2007, the Company continued to recognize its
revenue upon shipments to the end customers. At December 31, 2007, all such shipments made to this distributor prior to August 30, 2007 had been sold by this distributor to end customers and therefore, there was no remaining deferred
revenue at that date.

Reclassification

The company has reclassified certain prior year amounts to conform to the current years presentation, including amounts for prior years included in its consolidated balance sheets with respect to its short-term and long-term deferred
tax assets.

Shipping and Handling costs

Shipping and handling costs incurred are included in cost of goods sold in the consolidated statements of operations.

Short-term
Investments

Short-term investments are carried at fair value, with the unrealized gains and losses, if any, net of tax, reported in
other comprehensive income. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as short-term investments are included in interest and dividend income. Quarterly, management
reviews the valuation of short-term investments and recognizes an impairment loss where the decline in value is deemed to be other than a temporary decline.

Short-term investments held by the Company at December 31, 2008 were primarily investments in mutual funds. Short-term investments held by the Company at December 31, 2007 consisted primarily of auction rate
securities, which are classified as long-term investments as of December 31, 2008 (see Note 4).

Stock-Based Compensation

In December 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based Payment (SFAS No. 123(R)), which replaces SFAS No. 123,
Accounting for Stock-Based Compensation (SFAS No. 123), and supersedes Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees (APB 25). SFAS No. 123(R) requires all share-based
payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values beginning with the first annual period after December 15, 2005. SFAS No. 123(R) requires that an
entity measure the cost of equity-based service awards based on the grant-date fair value of the award and recognize the cost of such award over the period during which the employee is required to provide service in exchange for the award (vesting
period). The pro forma disclosures previously permitted under SFAS No. 123 are no longer an alternative to financial statement recognition. The Company adopted SFAS No. 123(R) on January 1, 2006 using the prospective transition
method, which required that all new stock-based awards granted subsequent to adoption be recognized in the financial statements at fair value.

For all periods prior to January 1, 2006, the Company accounted for stock-based compensation arrangements with directors, officers and employees utilizing the intrinsic-value method under Accounting

Principles Board (APB) No. 25, Accounting for Stock Issued to Employees, and related interpretations, and provided pro forma disclosure applying
the minimum value method recognition provisions of SFAS No. 123, Accounting for Stock-Based Compensation, to stock-based awards.

Stock-based compensation arrangements with non-employees are accounted for utilizing the fair value method or, if a more reliable measurement, the value of the services or consideration received. The resulting compensation expense is
recognized for financial reporting over the term of performance or vesting.

Translation of Foreign Currency

The financial statements of MEMSIC Semiconductor are translated into United States dollars in accordance with SFAS No. 52, Foreign Currency
Translation. The functional currency of MEMSIC Semiconductor, the Renminbi, is translated into United States dollars utilizing the following method: assets and liabilities are translated at exchange rates in effect at the end of the year, and
revenues and expenses are translated at the weighted average exchange rates during the year. Cumulative translation gains and losses are included as a separate component of stockholders equity (deficit) and reported as a part of comprehensive
income (loss). Transaction gains and losses are included in the consolidated statements of operations as incurred.

Warranty Reserve

The Companys products are warranted against manufacturing defects for twelve months following the date of sale (eighteen
months following date of sale to a distributor). Products returned under the provisions of the warranty agreement require the pre-approval of the Company. The Companys sole obligation under the provisions of the warranty agreement is to
replace or repair the product. Reserves for potential warranty claims are provided at the time of revenue recognition and are based on several factors including historical claims experience, current sales levels and the Companys estimate of
repair costs. To date, warranty expenses have not been significant.

Stock Split

On November 9, 2007, the Companys board of directors approved a 1-for-2 reverse stock split of the Companys outstanding common stock. The
reverse stock split became effective on November 20, 2007 and all common share and per share amounts in the accompanying consolidated financial statements and notes to the consolidated financial statements have been retroactively adjusted for
all periods presented to give effect to the reverse stock split.

Recent Accounting Pronouncements

In April 2008, the FASB issued FASB Staff Position (FSP) 142-3, Determination of the Useful Life of Intangible Assets, which amends the factors
that must be considered in developing renewal or extension assumptions used to determine the useful life over which to amortize the cost of a recognized intangible asset under SFAS No. 142. The FSP is effective for financial statements for
fiscal years beginning after December 15, 2008. The Company is currently evaluating the impact that the adoption of this FSP will have on its consolidated financial statements.

In December 2007, the FASB issued SFAS 141(R), Business Combinations(SFAS 141(R)). This statement is to improve the relevance, representational
faithfulness, and comparability of the information that a reporting entity provides in its financial reports about a business combination and its effects. This statement is effective prospectively for business combinations for which the acquisition
date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. The Company is currently evaluating the impact that the adoption of SFAS 141(R) may have on its 2009 consolidated financial
statements.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial
LiabilitiesIncluding an amendment of FASB Statement No. 115(SFAS 159). SFAS 159 permits

entities to choose to measure financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value
option has been elected will be recognized in earnings at each subsequent reporting date. This statement is effective for financial statements issued for fiscal years beginning after November 15, 2007. SFAS 159 was effective for the Company on
January 1, 2008. The adoption of the provisions of SFAS 159 did not have any impact on the Companys financial position and results of operations.

4. LONG-TERM INVESTMENTS

Investments held by the Company at December 31, 2008 consisted primarily of auction rate
securities, or ARS, and are considered available for sale. These securities reset the interest or dividend rates by auctions held at intervals of 7, 28, 35 or 49 days, and at such dates the Company has the option to sell such securities. The auction
rate securities held by the Company have high credit quality ratings of at least AAA/Aaa and contractual maturities of greater than 10 years.

These investments are carried at fair value, with the unrealized gains and losses, if any, net of tax, reported in other comprehensive income. The cost of securities sold is based on the specific identification method. Interest and
dividends on securities classified as short-term investments are included in interest and dividend income. Quarterly, management reviews the valuation of short-term investments and considers whether any decline in value is deemed to be other than a
temporary decline.

At December 31, 2008, the Company held two ARS investments: Illinois Educational Facilities Authority Select
Auction Variable Rate Securities having a value at par of $3.0 million and Montana Health Facility Authority Select Auction Variable Rate Securities having a value at par of $2.8 million. The Company has classified these investments as long-term
assets due to liquidity issues that have recently been experienced in global credit and capital markets as well as failed auctions during 2008. A failed auction means that the amount of securities submitted for sale at auction exceeded the amount of
purchase orders. If an auction fails, the issuer becomes obligated to pay interest at penalty rates, and all of the auction rate securities the Company holds continue to pay interest in accordance with their stated terms. However, the failed
auctions create uncertainty as to the liquidity of these securities.

Based on the Companys expected operating cash flows, and other
sources of cash, the Company does not expect the potential lack of liquidity in these investments to affect its ability to execute its current business plan in the near term.

Fair Value Measurement

The Company adopted the provisions of SFAS No. 157, Fair Value
Measurements (SFAS No. 157) relating to assets and liabilities recognized or disclosed in the financial statements at fair value on a recurring basis on January 1, 2008. The adoption of these provisions did not have a material effect
on the Companys consolidated financial statements.

SFAS 157 clarifies that fair value is an exit price, representing the price that
would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants based on the highest and best use of the asset or liability. As such, fair value is a market-based measurement that should be
determined based on assumptions that market participants would use in pricing an asset or liability. SFAS 157 requires the Company to use valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of
unobservable inputs. These inputs are prioritized as follows:



| | Level 1: | Observable inputs such as quoted prices for identical assets or liabilities in active markets
| | -------- | ---------------------------------------------------------------------------------------------



| | Level 2: | Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities or market-corroborated inputs
| | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------



| | Level 3: | Unobservable inputs for which there is little or no market data and which require the Company to develop its own assumptions about how market participants would price the assets or
liabilities
| | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Company historically accounted for the ARS held in its portfolio as available-for-sale
investments. The carrying value of these ARS approximated fair value due to the frequent resetting of the interest rate. While the Company continues to earn interest on those investments involved in failed auctions at the specified contractual rate,
due to the failed auctions and the illiquidity of these securities under current market conditions, the Company has considered whether par value continues to be a reasonable basis for estimating the fair value of these ARS at December 31, 2008.
The Company therefore estimated the fair value of these securities at December 31, 2008 using broker valuations and internally-developed models of the expected future cash flows related to the securities. One of the more significant assumptions
made in the Companys internally-developed models was the term of expected cash flows of the underlying auction rate securities and the discount related to the illiquidity of the investments. The Company developed several scenarios for the
liquidation of the auction rate securities over periods that ranged from 3 to 5 years. In estimating the fair value of these investments, the Company considered the financial condition and near-term prospect of the issuers, the magnitude of the
losses compared to the investments cost, the length of time the investments have been in an unrealized loss position, the low probability that the Company will be unable to collect all amounts due according to the contractual terms of the
security, whether the security has been downgraded by a rating agency, and the Companys ability and intent to hold these investments until the anticipated recovery in market value occurs.

Based on the Companys internal modeling, the Company recorded a temporary unrealized impairment loss of $247,000 in other comprehensive loss at
December 31, 2008 and wrote down the carrying value of these securities accordingly, from $5.8 million to $5.6 million. Based on the estimated operating cash flows and other sources of cash, the Company intends to hold these auction rate
securities for the foreseeable future, if necessary.

The Company continues to monitor the market for auction rate securities and adjust
its impact on the fair value of the Companys investments. If current market conditions deteriorate further, the Company may be

required to record additional temporary unrealized losses in other comprehensive income (loss) or, if the decline in fair value is judged to be
other-than-temporary, the cost basis of the individual security may be written off to fair value as a new cost basis and the amount of the write-down would be reflected as a charge to earnings.

The Company began the construction of two new buildings adjacent to its current facility in
December of 2007. Upon completion, the new facility is expected to comprise 20,800 square meters, consisting of 8,700 square meters housing for a new research and development institute, and 12,100 square meters of new manufacturing facilities.
Construction on the new facility is expected to be completed in two phases. Phase one includes the structural construction of the two new buildings and furnishing and fitting out the office building. Phase two includes the furnishing and equipment
of the manufacturing facility. The structural construction portion of phase one is expected to be completed at the end of the second quarter of 2009. As part of the Companys expense reduction program, the Company has temporarily deferred the
process of furnishing and fitting out the office building, pending more favorable economic conditions. The additional capital to complete phase one structural construction is estimated to be $1.6 million. The Company does not believe any impairment
has occurred since its intention to utilize the new facility in its own operations has not changed. Phase two construction has been deferred pending the completion of phase one construction.

The significant features of the Preferred Stock, including previous redemption rights, which
existed prior to the completion of the initial public offering were as follows:

Liquidation Rights

The holders of Preferred Stock had the right to a liquidation preference, which could be exercised by the preferred stockholders under certain events
outside of the Companys control. The liquidation values were determined as follows:



|          |  |

|          | 
|Series B: |  | the greater of (a) $1.1889 per share plus any cumulative dividends compounded annually and, any declared and unpaid dividends, or (b) fair value of common stock prior to such liquidation
event.
|          | 
|Series C: |  | the greater of (a) $1.50 per share plus any declared and unpaid dividends, or (b) fair value of common stock prior to such liquidation event.                                                    
|          | 
|Series D: |  | the greater of (a) $0.55, or (b) fair value of common stock prior to such liquidation event.                                                                                                     

A liquidation event included any of the following events; (i) voluntary or involuntary
liquidation, (ii) dissolution, or winding up of the Company, (iii) merger or consolidation of the Company or a subsidiary of the Company into or with another corporation, and (iv) sale of all or substantially all of the assets of the
Company.

Dividends

Holders of Series A and Series B convertible preferred stock were entitled to cumulative dividends at an annual rate of 8% and holders of Series C and Series D convertible preferred stock were entitled to cumulative
dividends at an annual rate of 3%. Such dividends were only payable when and if declared by the Companys board of directors.

No
dividends could be declared or paid to common stockholders prior to declaration and payment of the cumulative dividends. After declaration and payment of cumulative dividends, holders of preferred stock were entitled to participate in dividends with
common stockholders.

Voting

Each holder of outstanding shares of the Preferred Stock was entitled to vote that number of shares equal to the number of shares of common stock into which the shares of Preferred Stock held by such holder was then convertible.

The Company had determined the classification and carrying value of the Preferred Stock as follows:

Carrying Value

Since the liquidation
preference remained in place subsequent to the elimination of the redemption feature and a deemed liquidation event was outside the control of the Company, the Company presented its Preferred Stock outside of permanent stockholders equity
(deficit) at dates prior to the initial public offering in accordance with ASR 268.

The Company measured the Preferred Stock at its
original purchase price since the deemed liquidation was not probable at any of the reporting dates. The carrying values of the Preferred Stock at December 18, 2007 were as follows:



|         |  |                   |           
|-------- |  | ----------------- | ----------
|         |  | December 18, 2007
|         |  | Carrying Value   
|Series A |  | $                 | 5,412,000 
|Series B |  |                   | 8,250,000 
|Series C |  |                   | 10,900,002
|Series D |  |                   | 8,966,600 
|         |  |                   |           
|         |  | $                 | 33,528,602
|         |  |                   |           

Conversion to Common Stock

The holders of Preferred Stock, at their option, were entitled to convert their shares into shares of common stock. Additionally, upon the closing of an
initial public offering of securities with net proceeds greater than $30 million and a price per share of $3.57 or greater, shares of Preferred Stock automatically converted into common stock. This ratio was subject to adjustment upon the occurrence
of certain events such as a stock split, subdivision of the Companys common stock, recapitalization of the Companys capital stock or the issuance of certain dilutive securities. At December 31, 2006 and December 19, 2007, the
conversion ratio for each series of Preferred Stock was two-for-one.

Upon conversion to common stock, the holders right to receive
cumulative undeclared dividends expired. Effective December 19, 2007 the Companys authorized capital stock included 10,000,000 shares of preferred stock with a $0.00001 par value per share, all of which were undesignated at
December 31, 2008 and 2007.

9. COMMON STOCK

On December 19, 2007, the Company completed an initial public offering. The holders of the Companys common stock including shares issued in this offering, are entitled to one vote for each share held.

In March 2001, the Company issued an officer of the Company a loan, bearing interest at 5.07% for $200,000 related to the purchase of
200,000 shares of restricted common stock. The principal amounts of the loan were forgiven through 2006, and the interest was forgiven in 2007.

The Company reserved 2,942,130 and 3,475,718 shares at December 31, 2008 and 2007 for options to purchase common stock.

10. STOCK
INCENTIVE PLAN

Description of Plan

On March 29, 2000, the Companys stockholders and board of directors approved the 2000 Omnibus Stock Plan (the Plan), as amended, under which 2,969,000 shares of the Companys common stock was reserved for
issuance to directors, officers, employees, and consultants. Options granted under the 2000 Plan may be incentive stock options, nonqualified stock options and/or restricted stock. The 2000 Plan provides that the exercise price of incentive stock
options must be at least equal to the market value of the Companys common stock at the date such option is granted. For incentive stock option grants to an employee who owns more than 10% of the outstanding shares of common stock of the
Company, the exercise price on the incentive stock option must be 110% of market value at the time of grant. Granted options expire in ten years or less from the date of grant and vest based on the terms of the awards, generally ratably over four
years.

On August 22, 2007, the Companys board of directors approved the 2007 Stock Incentive Plan, (the 2007 Plan),
under which 3,000,000 shares of the Companys common stock are available for issuance. At the adoption date, 1,500,000 shares were reserved for issuance. The reserved amount will increase by 300,000 shares in each of the five anniversaries from
the adoption date, for an aggregate of 3,000,000 shares issuable under the 2007 Plan. In November 2007, the Companys board of directors approved to close the 2000 Plan and transferred the remaining options of 26,425 shares available for grant
under the 2000 plan to the 2007 plan increasing the initial number of shares available for issuance from 1,500,000 to 1,526,425.

Prior to
December 19, 2007, there was no public market for the Companys common stock. Accordingly, the board of directors determined the market value of the common stock at the date of grant by considering a number of relevant factors, including
the Companys operating and financial performance and corporate milestones achieved, the prices at which shares of convertible preferred stock in arms-length transactions were sold, the composition of and changes to the management team,
the superior rights and preferences of securities senior to the common stock at the time of each grant and the likelihood of achieving a liquidity event for the shares of common stock underlying stock options.

Determination of Fair Value of Common Stock

The Company had the following option grants during 2007 prior to the completion of its initial public offering:

| | Board with input from management based on the estimated fair value of its common stock. Subsequently, the Company had retrospective valuation reports
prepared by a third party valuation specialist to support the fair value of the options granted and determined the fair value to be $6.84 for the options granted in July and $7.64 for the options granted in August. As a result of the valuation
reports, the grants were modified to increase their respective exercise prices to the reported fair values.

The Company
issued Series D convertible preferred stock at $2.20 in April 2007.

At the time of these option grants, the exercise price was determined
by the Board with input by management based on the various objective and subjective factors mentioned above as well as valuation reports when available. The fair value per share is being recognized as compensation expense over the applicable vesting
period (which corresponds to the service period).

The Company engaged an independent third party to assist management in preparing
retrospective valuation reports to support the fair value of options granted during 2007. Management believes that the valuation methodologies used in the retrospective valuations are consistent with the Practice Aid of the American Institute of
Certified Public Accountants entitled Valuation of Privately Held Company Equity Securities Issued as Compensation.

In each
retrospective valuation, a probability-weighted combination of the guideline public company method and the discounted future cash flow method was used to estimate the aggregate enterprise value of the Company at the applicable valuation date. The
guideline public company method estimates the fair market value of a company by applying to that company market multiples, in this case revenue and EBITDA multiples, of publicly traded firms in similar lines of business. The companies used for
comparison under the guideline public company method were selected based on a number of factors, including but not limited to, the similarity of their industry, business model, financial risk and other factors to those of the Companys. Equal
weighting has been applied to the valuations derived from using the revenue and EBITDA multiples in determining the guideline public company fair market value estimate. The discounted future cash flow method involves applying appropriate
risk-adjusted discount rates between 18-25% to estimated debt-free cash flows, based on forecasted revenues and costs. The projections used in connection with this valuation were based on the Companys expected operating performance over the
forecast period. There is inherent uncertainty in these estimates; if different discount rates or assumptions had been used, the valuation would have been different.

In order to allocate the enterprise value determined under the guideline public company method and the discounted future cash flow method to its common stock, the Company used the probability-weighted expected return
method. Under the probability-weighted expected return method, the fair market value of the common stock is estimated based upon an analysis of future values for the Company assuming various future outcomes, the timing of which is based on the plans
of its board and management. Share value is based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes available as well as the rights of each share class. The fair market value
of the Companys common stock was estimated using a probability-weighted analysis of the present value of the returns afforded to its shareholders under each of four possible future scenarios.

Three of the scenarios assume a shareholder exit, either through an initial public offering (IPO), a sale of the Company to a strategic acquirer, or
dissolution of the company at or below liquidation preference. The fourth scenario assumes operations continue as a private company and no exit transaction occurs. For the IPO scenario, the estimated future and present values for the Companys
common stock was calculated using assumptions including; the expected pre-money valuation (pre-IPO) based on the guideline public company method discussed above; the anticipated dates of the future expected IPO; and an appropriate risk-adjusted
discount rate. For the sale scenario, the estimated future and present values for the Companys common stock was calculated using assumptions including: an equal weighting of the guideline public company method and the discounted cash flow
method discussed above; the expected dates of the future expected sale and an appropriate risk-adjusted discount rate. For the dissolution scenario, all of the proceeds are distributed to the preferred shareholders. No proceeds are available for
distribution to the common shareholders, and the value of the common stock is zero. For the

private company with no exit scenario, an equal weighting of the guideline public company method and the discounted cash flow method based on present day
assumptions was used. Finally, the present value calculated for the Companys common stock under each scenario was probability weighted based on managements estimate of the relative occurrence of each scenario.

Based upon the private equity fund raisings through April 2007, the Company placed approximately 25% probability on the Company going public and 35%
probability of the sale of the Company. The Company increased the probability of the initial public offering to 60% and decreased the probability of a sale to 30% in June 2007. In August 2007, the Company increased the probability of the initial
public offering to 70% and decreased the probability of a sale to 20% in connection with option grants made in August 2007. In September 2007, the Company increased the probability of the initial public offering to 85% and decreased the probability
of a sale to 10%.

Valuation of Stock Options

The Company has incorporated the fair values determined in the retrospective valuations for the stock options granted prior to the initial public offering in 2007 and the market value for stock options granted post
the initial public offering into the Black-Scholes option pricing model when calculating the compensation expense to be recognized. The key input assumptions used in the Black-Scholes option pricing model include; (i) the risk-free interest
rate is based on the yield available on U.S. Treasury zero-coupon bonds at the date of grant with maturity dates approximately equal to the expected life at the grant date, (ii) the expected life of the options is based on evaluations of
historical and expected future employee exercise behavior; (iii) volatility is based on historic volatilities from traded shares of a selected publicly traded peer group, believed to be comparable after consideration of size, maturity,
profitability, growth, risk and return on investment; and (iv) dividend yield, the Company has not paid dividends in the past and it does not expect to in the foreseeable future. The Company utilizes historical data to estimate pre-vesting
forfeitures and records stock-based compensation expense only for those awards that are expected to vest.

The fair value of each option
grant was estimated on the date of grant utilizing the following assumptions:

|Forfeitures             |  | 27%-39%   |  | 22-30%   

For the years ended December 31, 2008 and 2007, the Company recorded stock-based compensation
expense for the fair value of stock options granted to the Companys employees and directors in the amount of $1,215,833 and $491,127, respectively. At December 31, 2008, total unrecognized stock-based compensation expense for stock
options granted to the Companys employees and directors was estimated to approximate $3.8 million.

For stock options issued in 2005,
the Company recorded a deferred stock compensation expense of $629,000 for the intrinsic value of these options applying the fair value provided from a valuation report on February 28, 2006. For the year ended December 31, 2008 and 2007,
the Company recorded stock-based compensation expense for these options in the amount of $80,858 and $103,075, respectively. At December 31, 2008, the total unrecognized stock-based compensation expense was approximately $32,259.

The intrinsic values (aggregate market value minus aggregate exercise price) of stock options
exercised during the years ended December 31, 2008 and 2007 were $141,669 and $201,983, respectively. The total fair value of options vested during December 31, 2008 and 2007 was approximately $1,231,000 and $309,500, respectively.

The Company has historically accounted for stock options granted to consultants using the fair value method for the calculation of
compensation cost. For the years ended December 31, 2008 and 2007, the Company recorded compensation expense for stock option grants to consultants in the amount of ($36,445) and $116,600, respectively.

The total unrecognized stock-based compensation expense related to the non-qualified common stock option grants to consultants expected to be charged to
operations was estimated to approximate $62,000 and $266,000, respectively, at December 31, 2008 and 2007.

The Company has a policy to reinvest any earnings of its MEMSIC Semiconductor in the Chinese
operations. The Company has not provided for U.S. income taxes that could result from the distribution of such earnings to the U.S. parent. If these earnings were ultimately distributed to the U.S. in the form of dividends or otherwise, or if the
shares of MEMSIC Semiconductor were sold or transferred, the Company would be subject to additional U.S. income taxes, net of impact of any available foreign tax credits. It is not practicable to estimate the amount of unrecognized deferred U.S.
taxes on these undistributed earnings. As of December 31, 2008, the Company had cumulative foreign earnings of $4.9 million. The Companys subsidiary in China is governed by the Income Tax Law of the Peoples Republic of China
concerning Foreign Investment Enterprises (FIEs) and Foreign Enterprises and various local income tax laws (the PRC Income Tax Law). Pursuant to the PRC Income Tax Law, wholly-owned foreign enterprises are subject to income
tax at a statutory rate of a 30% foreign enterprise income tax (FEIT), and a 3% local income tax.

On March 16, 2007, the
National Peoples Congress approved and promulgated a new tax law named Enterprise Income Tax Law, which took effect beginning January 1, 2008. Under the new tax law, FIEs and domestic companies are subject to a uniform tax
rate of 25%. The new tax law provides a five-year transition period starting from its effective date for those enterprises which were established before the promulgation date of the new tax law and which were entitled to a preferential lower tax
rate under the then effective tax laws or regulations. In accordance with regulations issued by the State Council, the tax rate of such enterprises may gradually transition to the uniform tax rate within the transition period. For those enterprises
which are enjoying tax holidays, such tax holidays may continue until their expiration in accordance with the regulations issued by the State Council, but where the tax holiday has not yet started because of losses, such tax holiday shall be deemed
to commence from the first effective year of the new tax law.

Since the Companys subsidiary in China qualifies as a high
technology enterprise specially supported by the PRC government, it is entitled to the reduced FEIT rate of 15% and is exempt from FEIT for its first two years of profitable operations after offsetting prior years tax losses and is
entitled to a 50% reduction in its FEIT for the following three years as approved by the tax authorities in accordance with the China Income Tax Law for Enterprises with Foreign Investment and Foreign Enterprises and its Implementation Rules issued
in 1991. In addition, the Companys MEMSIC Semiconductor is exempted from the 3% local income tax during the above preferential tax treatment periods of five years pursuant to the Rule Concerning Exemption or Reduction of Local Income Tax for
Foreign Invested Enterprises issued by the Peoples Government of Guangdong Province issued in 1992.

However, according to the
relevant transition preferential tax policies issued by the State Council on March 16, 2007, the preferential enterprise income tax rate under the new tax law and the transition-period preferential tax policy can not apply simultaneously. That
is to say, MEMSIC Semiconductor may either choose to enjoy the exemption from enterprise income tax for 2007 and 2008 and a 50% reduction on the uniform enterprise income tax rate of 25% from 2009 to 2011, or, choose the preferential enterprise
income tax rate of 15% for qualified high-technology companies under the new tax law. The Company believes the adoption of the transition-period preferential tax policy will be more beneficial to MEMSIC Semiconductor.

At December 31, 2008, the MEMSIC Semiconductor ended its second year of the two-year tax holiday and
expects to apply a 50% reduced uniform enterprise income tax rate from 2009 to 2011 resulting in an effective rate of 12.5%.

Of the $1,275,608 valuation allowance, $84,600 was recorded through other comprehensive income
related to temporary decline of the long-term investment balance.

The deferred tax assets related to temporary differences of the
Companys China subsidiary for the years ended December 31, 2008 and 2007 amounted to $114,643 and $0, respectively.

As of the
fourth quarter of 2008, the Company entered into a three-year cumulative loss position in the United States and concluded that a valuation allowance was appropriate for its deferred tax assets in the United States. After considering all sources of
taxable income for the carryover period in accordance with SFAS No. 109, the Company recorded a full valuation allowance against its deferred tax assets based upon uncertainty with respect to future taxable income in the United States.

At December 31, 2008, the Company had gross U.S. net operating loss carryforwards of $1.4 million, which expire in the year 2028. Included
within this amount is approximately $258,000 of excess tax deductions associated with non-qualified stock options that have been exercised. When these excess tax benefits actually result in a reduction to currently payable income taxes, the tax
benefit will be recorded as an increase to additional paid-in capital. The Companys operating losses may be subject to limitations under provisions of the Internal Revenue Code.

On July 13, 2006, the FASB issued FASB Interpretation (FIN) No. 48, Accounting for Uncertainty in Income Taxesan
Interpretation of FASB Statement 109, which fundamentally changes the way that the Company will be required to treat its uncertain tax positions for financial accounting purposes. FIN No. 48 prescribes rules regarding how the Company should
recognize, measure and disclose in its financial statements tax positions that were taken or will be taken on the Companys tax return that are reflected in measuring current or deferred income tax assets and liabilities for interim or annual
periods. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in an increase in a liability for income taxes payable, or a reduction in a deferred tax asset or an increase
in a deferred tax liability. On January 1, 2007, the Company adopted FIN 48. At the adoption date, the Company did not have any unrecognized tax benefits and determined the impact of FIN 48 was not material to the Companys consolidated
financial statements. During 2007, no new additional unrecognized tax benefits were identified.

14. COMMITMENTS AND CONTINGENCIES

Lease Commitments

The Company leases its United States corporate headquarters facility, sales
offices and certain equipment under non-cancelable operating leases expiring through 2012. The Company owns the property utilized for manufacturing and certain other operations located in Wuxi, Jiangsu Province, in the PRC.

At December 31, 2008, future minimum annual non-cancelable operating lease commitments were $190,000, $159,000, $144,000, $144,000 and $60,000 for

Licensing Agreement and Marketing Agreements

In connection with the initial capitalization, the Company was assigned a technology license related to the design, manufacture and sale of low-cost thermal accelerometers from Analog Devices, Inc. The Company agreed to fulfill the
obligations under the technology license, including royalty obligations to a university and patent prosecution expenses. While the Company believes that the agreements as a whole provide it with exclusive rights to the license and the patents, there
can be no assurance that, if a third party challenges the validity of the patents, the Company will prevail and continue exclusive rights to the licensed technology and patents.

The license agreement requires that the Company pay the university a quarterly royalty of 1% of net sales, not to exceed $100,000 per year, during the
term of the license agreement. The Company paid royalty fees in the amount of $100,000 in each of the two years ended December 31, 2008 and 2007, and recorded such amounts to general and administrative expenses in the consolidated statements of
operations.

Employee Benefit Plan

The Company maintains a 401(k) retirement savings plan (the Plan) whereby employees may elect to defer a portion of their salary and contribute the deferred portion to the Plan. The Plan covers substantially all U.S. employees of the
Company. The Company contributes an amount equal to 100% of the amount contributed by each employee, up to 2% of their base compensation. The Companys matching contributions vest over a four year period. Employee contributions and the
Companys matching contributions are invested in one or more collective investment funds at the participants direction. For the years ended December 31, 2008 and 2007, the Companys contributions, including administrative fees,
were approximately $24,937 and $32,246, respectively.

General

The Company is subject to potential claims in the normal course of business and on occasion, may be named as a defendant in lawsuits. There is no pending claim that the Company believes would, if decided adversely to
the Company, have a material impact on the Companys accompanying financial statements.

15. SEGMENT INFORMATION

The Company conducts its operations and manages its business in one segment, the development and design, manufacture and sale of semiconductor sensor
systems solutions based on micro electromechanical systems (MEMS) technology and advanced integrated circuit design. Within this segment, the Companys chief executive officer views the operations of the manufacturing unit and the sales and
marketing organizations as an integrated business unit and utilizes enterprise wide operating results as one factor in making operating decisions.

|-------- | -----------------------

Disclosure
Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated
the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as December 31, 2008. Based on this evaluation, our chief executive officer and chief financial officer concluded
that, as of December 31, 2008, our disclosure controls and procedures were (1) designed to ensure that material information relating to our company, including our consolidated subsidiaries, is made known to our chief executive officer and
chief financial officer by others within those entities, particularly during the period in which this report was being prepared and (2) effective, in that they provide reasonable assurance that information required to be disclosed by us in the
reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms.

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable, and not absolute,
assurance that the objectives of the control system will be met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events and the application of judgment in evaluating the
cost-benefit relationship of possible controls and procedures. Because of these and other inherent limitations of control systems, there is only reasonable assurance that our controls will succeed in achieving their goals under all potential future
conditions.

Based on the evaluation of our disclosure controls and procedures as of December 31, 2008, our Chief Executive Officer
and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Internal Control over Financial Reporting

(a) Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for the assessment of the
effectiveness of internal control over financial reporting. As defined by the Securities and Exchange Commission, internal control over financial reporting is a process designed by, or under the supervision of our principal executive and principal
financial officers and effected by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements in accordance
with U.S. generally accepted accounting principles.

Our 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 our transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to
permit preparation of the consolidated financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors;
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 consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

##### Table of Contents

In connection with the preparation of our annual consolidated financial statements, management has
undertaken an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission, or the COSO Framework. Managements assessment included an evaluation of the design of our internal control over financial reporting and testing of the operational effectiveness of those controls. Based
on this evaluation, management has concluded that our internal control over financial reporting is effective as of December 31, 2008 based on those criteria.

This Annual Report on Form 10-K does not include an attestation report of our registered public accounting firm, as permitted by the transition rules of the Securities and Exchange Commission applicable to newly
public companies.

Committees of the Board of Directors

Our board of directors has established an audit committee, a compensation committee and a nominating committee, which are the only standing committees of
the board of directors.

Audit committee. Our audit committee consists of Messrs. Tung, Yang and Zavracky, with Mr. Tung
serving as chair. Our audit committee oversees our corporate accounting and financial reporting process and internal controls over financial reporting. Our audit committee evaluates the qualifications, independence and performance of our independent
registered public accounting firm, Ernst & Young LLP; engages and determines the compensation of the independent auditor; approves the retention of the independent auditor to perform any proposed permissible non-audit services; reviews our
financial disclosures, including our critical accounting policies and internal controls over financial reporting; prepares an annual report to our stockholders for inclusion in our proxy statement; reviews and approves in advance any proposed
related party transactions; and discusses with management and the independent auditor the results of the annual audit and our financial statements. We believe that our audit committee members meet the requirements for independence and financial
literacy under the current requirements of the Sarbanes-Oxley Act of 2002, The Nasdaq Global Market and SEC rules and regulations. In addition, the board of directors has determined that Mr. Tung is qualified as an audit committee
financial expert within the meaning of the SEC rules and regulations.

Compensation committee. Our compensation committee
consists of Messrs. Blethen, Yang and Zavracky, with Mr. Blethen serving as chair. Our compensation committee administers our stock option plans and employee stock purchase plans; recommends to our board of directors the compensation of our
executive officers; prepares a report of the committee required by the rules of the SEC to be included in our proxy statement; recommends to our board of directors any performance-based awards to be granted to any of our executive officers or other
employees; recommend to our board of directors the terms and conditions of any employment agreement and any arrangements regarding severance or change of control payments with any of our executive officers; recommend to our board of directors, and
review periodically, the compensation of our directors, recommend to our board of directors, and review periodically, the composition of our plans and programs for employee compensation. We believe that each member of our compensation committee
meets the requirements for independence under the rules of The Nasdaq Global Market.

Nominating committee. Our nominating committee
currently consists of Messrs. Tung and Zavracky, with Dr. Zavracky serving as chair. Our nominating committee identifies individuals qualified to become members of the board and to recommend to our board of directors nominees for election as
directors. We believe that Messrs. Tung and Zavracky meet the independence requirements under the rules of The Nasdaq Global Market.

2008 Director
Compensation

Historically, we have not provided cash compensation to directors for their services as directors or members of
committees of our board of directors, nor have we compensated our directors who are affiliated with venture capital firms that are significant stockholders of our company for their services as directors. Messrs. Blethen and Zavracky received
compensation in the form of non-qualified stock options. We reimbursed directors for their reasonable expenses incurred in attending meetings of our board of directors and of committees of our board of directors.

In February 2008, our board of directors adopted a new policy for compensation of our non-employee directors, under which they receive cash retainers
(payable quarterly in arrears), per meeting fees and annual stock option awards, as follows:



| |  |  | Each non-employee director receives a cash retainer in the amount of $20,000 per year;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | Our lead director and chairpersons of our standing committees receive additional annual cash retainers, as follows: lead director, $20,000; audit committee chair,
$10,000; compensation committee chair, $7,500; and nominating committee chair, $5,000;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

non-employee director will receive upon such election a non-qualified stock option to purchase 20,000 shares of our common stock;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

follows: all non-employee directors, $2,500 per board meeting; audit committee chair, up to $1,500 per audit committee meeting; compensation committee chair, $2,500 per compensation committee meeting; and other members of our standing committees,

Director Candidates and
Selection Process

Our nominating committee is responsible for identifying and reviewing candidates to fill open positions on the
board of directors, including positions arising as a result of the expiration of the term, removal, resignation or retirement of any director, an increase in the size of the board or otherwise, and recommending to our full board candidates for
nomination for election to the board. In recommending new directors, the committee will consider any requirements of applicable law or listing standards, a candidates strength of character, judgment, business experience and specific area of
expertise, factors relating to the composition of the board (including its size and structure), principles of diversity, and such other factors as the committee deems to be appropriate.

The committee is responsible for reviewing from time to time the appropriate skills and characteristics required of board members in the context of the
current make-up of the board, including such factors as business experience, diversity, and personal skills in technology, finance, marketing, sales, financial reporting and other areas that contribute to an effective board.

Stockholders may recommend individuals to the nominating committee for consideration as potential
director candidates by submitting their names, together with appropriate biographical information and background materials and a statement as to whether the stockholder or group of stockholders making the recommendation has beneficially owned more
than 5% of our common stock for at least a year as of the date such recommendation is made, to our nominating committee, c/o Corporate Secretary, MEMSIC, Inc., One Tech Drive, Suite 325, Andover, Massachusetts 01810. Assuming that appropriate
biographical and background material has been provided on a timely basis, the nominating committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it
follows for candidates submitted by others. If the board determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included in our proxy card for the next annual meeting. Any
recommendation of a potential director nominee should also include a statement signed by the proposed nominee expressing a willingness to serve on our board if elected. As part of this responsibility, the committee will be responsible for
conducting, subject to applicable law, any and all inquiries into the background and qualifications of any candidate for the board and such candidates compliance with the independence and other qualification requirements established by the
committee or imposed by applicable law or listing standards.

|(1) | Amounts shown do not reflect compensation actually received by the named executive officer. The amounts shown are calculated on the same basis as that we used in determining the
expense recognized in our 2008 and 2007 consolidated financial statements in accordance with SFAS 123(R), except that we have disregarded any estimate of future forfeitures related to service-based vesting conditions with respect to such option
awards. Except for the forfeiture of stock options to purchase 157,500 shares of our common stock held by our former Vice President  Marketing and Business Development, Patrick Chiumiento and 275,000 shares of our common stock held by our
former Chief Financial Officer, Shang Hsiao, there were no actual forfeitures of stock options by any named executive officer in 2008. The other assumptions used to calculate the expense amounts shown for stock options granted in 2008 and 2007 are
described in Note 10 to the consolidated financial statements in this Annual Report on Form 10-K. All options awards disclosed in this table vest as to 25% of the maximum number of shares issuable pursuant to such award on the first anniversary of
the vesting start date, as set by our board of directors, and vest as to an additional 25% of the shares on each subsequent anniversary of the vesting start date, such that each option will be fully vested on the fourth anniversary of the vesting
start date.

Employment arrangements with named executive officers

Change in ControlAgreements.On March 26, 2009, we entered into Senior Executive Change in Control Agreements, or the Change
in Control Agreements, with Yang Zhao and Patricia Niu. These agreements provide for the acceleration of vesting of stock options held by Dr. Zhao and Ms. Niu if, after a change in control we terminate the executives employment without cause
or the executive terminates his or her employment due to a breach by us (as each event is defined in the Change in Control Agreements). Once the acceleration provisions of the Change in Control Agreements are triggered, the vesting of each option
held by the executive shall be accelerated such that a portion of such options equal to the portion that would otherwise have vested during the last year of the vesting schedule shall become exercisable immediately. This acceleration shall be
applied after, and not in lieu of, any accelerated vesting that may be provided for under the terms of such option and any plan under which such option was granted and by any resolution of our board of directors or any committee thereof. However, to
the extent that the total acceleration of vesting that each executive would receive exceeds a combined total of twenty-four (24) months then the provisions of these Change in Control Agreements shall not apply.

Separation Agreement with Patrick Chiumiento. On December 22, 2008, Patrick Chiumiento resigned as our Vice President of Marketing and
Business Development. In connection with Mr. Chiumientos resignation, we entered into a Separation Agreement with him pursuant to which Mr. Chiumiento provided us with a release and customary confidentiality, non-solicitation and
other covenants and in exchange received severance pay in an amount equal to three months base salary.
