Risk Factors

Risks Relating to Economic Conditions and the Financial Markets

The global credit and financial markets crisis could materially and adversely affect our business and results of operations.

In 2008, 2009 and continuing into 2010, global credit and financial markets have experienced severe disruptions. These include diminished
liquidity and limited availability of credit, reduced consumer confidence, reduced economic growth, increased unemployment rates and uncertainty about economic stability. Limited availability of credit in financial markets may lead consumers and
businesses to postpone spending. This in turn may cause our customers to cancel, decrease or delay their existing and future orders with us. Financial difficulties experienced by our customers or suppliers as a result of these conditions could lead
to production delays and delays or defaults in payment of accounts receivable. Continuing credit markets disruption restricts our access to capital and limits our ability to fund operations or to refinance maturing obligations as they become due
through additional borrowing or other sources of financing. We are not able to predict the duration or extent of the current global credit and financial markets crisis. These conditions increase the difficulty of accurately forecasting and planning
our business activities. If these conditions and uncertainties continue or if credit and financial markets and confidence in economic conditions further deteriorate, our business and results of operations could be materially and adversely affected.

Risks Relating to Our Industry

Because we depend on the highly cyclical semiconductor industry, which is characterized by significant and sometimes prolonged downturns from time
to time, our net revenue and earnings may fluctuate significantly, which in turn could cause the market price of our common shares to decline.

Because our business is, and will continue to be, dependent on the requirements of semiconductor companies for independent testing and
assembly services, any downturn in the highly cyclical semiconductor industry may reduce demand for our services and adversely affect our results of operations. All of our customers operate in this industry and variations in order levels from our
customers and in service fee rates may result in volatility in our net revenue and earnings. For instance, during periods of decreased demand for assembled semiconductors, some of our customers may even simplify, delay or forego final testing of
certain types of semiconductors, such as dynamic random access memory, or DRAM, further intensifying our difficulties. From time to time, the semiconductor industry has experienced significant, and sometimes prolonged, downturns, which have
adversely affected our results of operations. In 2009, the semiconductor industry, especially the assembly and testing services for DRAM products sector, continued to experience the significant downturn that began in fourth quarter of 2008, and
which has adversely affected our business. As a result of the industry downturn, our net revenue for 2009 decreased 29% from 2008 levels. We incurred a net loss of NT$4,419 million (US$138 million) in 2009, a decrease from a net loss of NT$7,270
million in 2008. This industry downturn started to recover from the second quarter of 2009, and we cannot give any assurances that there will not be any downturn in the future or that any future downturn will not affect our results of operations.

Any deterioration in the market for end-user applications for semiconductor products would reduce demand for our services and may
result in a decrease in our earnings.

Market conditions in the semiconductor industry track, to a large degree, those
for their end-user applications. Any deterioration in the market conditions for the end-user applications of semiconductors we test and assemble could reduce demand for our services and, in turn, materially adversely affect our financial condition
and results of operations. Our net revenue is largely attributable to fees derived from testing and assembling semiconductors for use in personal computers, communications equipment, consumer electronic products and display applications. A
significant decrease in demand for products in these markets could put pricing pressure on our testing and assembly services and negatively affect our net revenue and earnings. The weak demand for LCD and other flat-panel display products that began
in 2007 adversely affected our operating results in 2007, 2008 and 2009. Any significant decrease in demand for end-user applications of semiconductors will negatively affect our net revenue and earnings.

A decline in average selling prices for our services could result in a decrease in our earnings.

Historically, prices for our testing and assembly services in relation to any given semiconductor tend to decline over the course of its
product and technology life cycle. See also  A decrease in market demand for LCD and other flat-panel display driver semiconductors may adversely affect our capacity utilization rates and thereby negatively affect our
profitability. If we cannot reduce the cost of our testing and assembly services, or introduce higher-margin testing and assembly services for new package types, to offset the decrease in average selling prices for our services, our earnings
could decrease.

A reversal or slowdown in the outsourcing trend for semiconductor testing and assembly services could reduce our
profitability.

In recent years, integrated device manufacturers, or IDMs, have increasingly outsourced stages of the
semiconductor production process, including testing and assembly, to independent companies like us to shorten production cycles. In addition, the availability of advanced independent semiconductor manufacturing services has also enabled the growth
of so-called fabless semiconductor companies that focus exclusively on design and marketing and outsource their manufacturing, testing and assembly requirements to independent companies. A substantial portion of our net revenue is
indirectly generated from providing semiconductor assembly and testing services to these IDMs and fabless companies. We cannot assure you that these companies will continue to outsource their testing and assembly requirements to independent
companies like us. A reversal of, or a slowdown in, this outsourcing trend could result in reduced demand for our services, which in turn could reduce our profitability.

Risks Relating to Our Business

If we are unable to compete effectively in the highly competitive semiconductor testing and assembly markets, we may lose customers and our income
may decline.

The semiconductor testing and assembly markets are very competitive. We face competition from a number
of IDMs with in-house testing and assembly capabilities and other independent semiconductor testing and assembly companies. Our competitors may have access to more advanced technologies and greater financial and other resources than we do. Many of
our competitors have shown a willingness to reduce prices quickly and sharply in the past to maintain capacity utilization in their facilities during periods of reduced demand. In addition, an increasing number of our competitors conduct their
operations in lower cost centers in Asia such as Mainland China, Thailand, Vietnam and the Philippines. Any renewed or continued erosion in the prices or demand for our testing and assembly services as a result of increased competition could
adversely affect our profits.

We are highly dependent on the market for memory products. A downturn in market prices for these products
could significantly reduce our net revenue and net income.

A significant portion of our net revenue is derived from
testing and assembling memory semiconductors. Our net revenue derived from the testing and assembly of memory semiconductors accounted for 78%, 75% and 66% of our net revenue in 2007, 2008 and 2009, respectively. In the past, our service fees for
testing and assembling memory semiconductors were sharply reduced in tandem with the decrease in the average selling price of DRAM in the semiconductor industry. The continuing oversupply of DRAM products in 2008 and the weak demand in the DRAM
market in 2009 resulted in significant reductions in the price of DRAM products, which in turn drove down the average prices for our testing and assembly services for DRAM products in these periods. We cannot assure you that there will not be
further downturns in DRAM prices in the future.

Weak demand for LCD and other flat-panel display driver semiconductors may adversely
affect our capacity utilization rates and thereby negatively affect our profitability.

Our testing and assembly
services for LCD and other flat-panel display driver semiconductors generated net revenue of NT$3,996 million, NT$2,805 million and NT$2,626 million (US$82 million) in 2007, 2008 and 2009, respectively. We invested NT$714 million, NT$157 million and
NT$37 million (US$1 million) in 2007, 2008 and 2009, respectively, on equipment for tape carrier package, or TCP, chip-on-film, or COF and chip-on-glass, or COG, technologies, which are used in testing and assembly services for LCD and other
flat-panel display driver semiconductors. Most of this equipment may not be used for technologies other than TCP, COF or COG. Our gross margin for testing and assembly services for LCD and other flat-panel display driver semiconductors was negative
21% in 2009 and negative 18% in 2008 primarily as a result of the weak demand for LCD and other flat-panel display products, which in turn decreased our capacity utilization rates and average selling prices. If demand for LCD and
other flat-panel display products does not increase, our capacity utilization rates may not increase, resulting in our inability to generate sufficient revenue to cover the significant depreciation expenses for the equipment used in testing and
assembling LCD and other flat-panel display driver semiconductors, and hereby further negatively affecting our profitability. See also  Because of our high fixed costs, if we are unable to achieve relatively high capacity utilization
rates, our earnings and profitability may be adversely affected.

Our significant amount of indebtedness and interest expense will
limit our cash flow and could adversely affect our operations.

We have a significant level of debt and interest
expense. As of December 31, 2009, we had approximately NT$13,378 million (US$419 million) and NT$4,738 million (US$148 million) in long- and short-term indebtedness, respectively, outstanding. Both the long- and short-term indebtedness amounts
include capital lease obligations. Of our long-term debt, we had NT$11,239 million (US$352 million) of bank loans, with an interest rate between 1.065% and 4.69%; US$42 million of convertible notes with an interest rate of 3.375%, 8% or 10%; and
capital lease obligations of NT$1,454 million (US$46 million), with an interest rate between 3.9567% to 3.9609%. In addition, ThaiLin, ChipMOS Taiwans 42.9% owned subsidiary, holds US$19 million in aggregate principal amount of the convertible
notes.

Our significant indebtedness poses risks to our business, including the risks that:



| |  |  | we may have to use a substantial portion of our consolidated cash flow from operations to pay principal and interest on our debt, thereby reducing the
funds available for working capital, capital expenditures, acquisitions and other general corporate purposes;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | insufficient cash flow from operations may force us to sell assets, or seek additional capital, which we may be unable to do at all or on terms
favorable to us;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our level of indebtedness may make us more vulnerable to economic or industry downturns; and
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | our debt service obligations increase our vulnerabilities to competitive pressures, because many of our competitors may be less leveraged than we are.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------

ChipMOS Bermuda and ChipMOS Taiwan were not able to meet their financial covenants under a
US$75 million Facility Agreement dated July 18, 2008 (the USD Facility Agreement) among ChipMOS Bermuda and the banks named therein, and the related Guarantee Agreement dated July 18, 2008 (the Guarantee Agreement)
among ChipMOS Taiwan, ChipMOS Bermuda and the banks named therein. In addition, ChipMOS Taiwan filed a bail-out application with the competent government authorities, and negotiated with its bank creditors for an extension of its debt repayment and
other types of settlement and with its equipment lessor and the lessors creditor to restructure its leasing arrangement. ChipMOS Taiwan has obtained such extension or settlement whereby ChipMOS Taiwan has provided additional collaterals.
ChipMOS Bermuda also negotiated with its bondholders to extend its debt repayments and other types of settlement, and has obtained such extension or settlement (the Settlement Agreement). ChipMOS Bermuda sent a waiver request to the
lending banks in April 2009 with respect to the effect of the foregoing arrangements on the USD Facility Agreement and the Guarantee Agreement. In February 2010, the agent of the USD Facility Agreement and the Guarantee Agreement, Standard Chartered
Bank (Hong Kong) Limited, confirmed to ChipMOS Bermuda that the majority lenders approved the waiver, subject to certain conditions and a waiver fee of 0.1% on the loan outstanding amount as of July 2, 2009.

On February 26, 2010, ChipMOS Bermuda and Siliconware Precision Industries Co., Ltd. (Siliconware Precision) entered
into a Share Purchase Agreement, whereby ChipMOS Bermuda agreed to sell 15.8% of ChipMOS Taiwans outstanding shares to Siliconware Precision. ChipMOS Bermuda sought the lending banks approval to (1) reduce its share holding
percentage in ChipMOS Taiwan, (2) repay the debts prior to maturity by March 2011 and (3) waive the break cost. As of the date of this Annual Report on Form 20-F, ChipMOS Bermuda has received approval from the lending banks for the
aforementioned waiver request under the USD Facility Agreement. Upon the completion of the Share Purchase Agreement, together with ChipMOS Bermudas currently available funds, ChipMOS Bermuda may have sufficient funds to repay the debts under
the USD Facility Agreement prior to the maturity date.

For additional information on our indebtedness, see Item 5.
Operating and Financial Review and ProspectsLiquidity and Capital Resources.

Our results of operations may fluctuate
significantly and may cause the market price of our common shares to be volatile.

Our results of operations have
varied significantly from period to period and may continue to vary in the future. Among the more important factors affecting our quarterly and annual results of operations are the following:



| |  |  | our ability to accurately predict customer demand, as we must commit significant capital expenditures in anticipation of future orders;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to quickly adjust to unanticipated declines or shortfalls in demand and market prices for our testing and assembly services, due to our
high percentage of fixed costs;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in prices for our testing and assembly services;
| | - |  | --------------------------------------------------------



| |  |  | volume of orders relative to our testing and assembly capacity;
| | - |  | ---------------------------------------------------------------



| |  |  | capital expenditures and production uncertainties relating to the roll-out of new testing or assembly services;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | our ability to obtain adequate testing and assembly equipment on a timely basis;
| | - |  | --------------------------------------------------------------------------------



| |  |  | changes in costs and availability of raw materials, equipment and labor;
| | - |  | ------------------------------------------------------------------------



| |  |  | changes in our product mix; and
| | - |  | -------------------------------



| |  |  | earthquakes, drought and other natural disasters, as well as industrial accidents.
| | - |  | ----------------------------------------------------------------------------------

Because of the factors listed above, our future results of operations or growth rates may be below the expectations of research analysts
and investors. If so, the market price of our common shares, and the market value of your investment, may fall.

The ongoing criminal proceeding of and adverse publicity associated with Mr. Shih-Jye Cheng, our
Chairman and Chief Executive Officer, and Mr. Hung-Chiu Hu, our former director, could have a material adverse effect on our business and cause our stock price to decline.

Mr. Shih-Jye Cheng, our chairman and chief executive officer, was indicted by the Taipei District Prosecutors Office, or the
prosecutor, in December 2005. Based upon information released by the prosecutor, the indictment alleges that Mr. Shih-Jye Cheng, as instructed by Mr. Hung-Chiu Hu, purchased repurchase notes on January 6, January 13, and
January 28, 2004 from Founder Associates Limited, a British Virgin Islands company affiliated with Mega Securities Co., Ltd. (formerly known as Barits International Securities Co., Ltd.), with an aggregate principal amount of approximately
US$29 million, by using corporate funds from ChipMOS Taiwan and ThaiLin. The indictment further alleges that these repurchase notes were used as a cover to misuse the corporate funds of Mosel, and its affiliated entities, including ChipMOS Taiwan
and ThaiLin, in violation of ROC law. In addition, the indictment alleges that Mr. Hu and others were engaged in the insider trading of the securities of Mosel in violation of ROC law, but none of the current officers at ChipMOS Taiwan or
ThaiLin was indicted in this regard.

On January 5, 2006, our board established a special committee to evaluate the
circumstances surrounding the indictment of Mr. Cheng. As of March 31, 2010, the special committee was comprised of two independent directors, Messrs. Yeong-Her Wang and Pierre Laflamme. The special committee engaged K&L Gates LLP
(formerly Kirkpatrick & Lockhart Preston Gates Ellis LLP) as its independent international legal counsel, Baker & McKenzie as its independent ROC legal counsel, and Ernst & Young (formerly Diwan, Ernst & Young) as
its financial advisor to assist in its investigation.

The special committees investigation focused on (1) the
probability that Mr. Shih-Jye Cheng would be convicted on the charges described in the indictment, (2) whether the indictment resulted in any pecuniary or other damage to us, (3) whether there were any internal control weaknesses
related to the investments in repurchase notes within ChipMOS Bermuda and its subsidiaries and (4) whether ChipMOS Bermuda is required by applicable laws or the NASDAQ Global Select Market listing requirements to take any action in connection
with the indictment. The special committee did not attempt to independently determine whether Mr. Cheng had engaged in any wrongdoing in connection with the investments in repurchase notes, irrespective of whether such wrongdoing would lead to
a conviction on the charges under the indictment.

On June 28, 2006, the special committee issued its report, including
its findings and recommendations. Based upon the results of its investigation, it found that (1) Mr. Shih-Jye Cheng has declared himself not guilty of the charges described in the indictment, (2) Baker & McKenzie, after
reviewing the indictment and the prosecutors exhibits, has found that the evidence produced by the prosecutor seems to be inadequate and that there is a low probability of the charges in the indictment being founded, (3) the financial
advisor to the special committee has found that we suffered no loss (not taking into account exchange rate factors) and that all monies (capital and interest) were remitted back to our subsidiaries involved, (4) we have suffered no identifiable
harm to our reputation or business and (5) Mr. Cheng has not been impaired by the indictment to perform as our chairman and chief executive officer. The special committee recommended that our board maintain Mr. Cheng as our chairman
and chief executive officer with full responsibilities and our board unanimously (with Mr. Cheng having recused himself) resolved to accept and adopt the special committees recommendation with regard to Mr. Cheng. Our board of
directors also resolved to continue the role of the special committee for the duration of the ongoing criminal proceeding involving Mr. Cheng to actively monitor any developments of the criminal investigation and take or recommend any
appropriate action in light of such developments.

On October 1, 2007, the Taipei District Court found Mr. Shih-Jye
Cheng not guilty, and on October 22, 2007, the prosecutor appealed the Taipei District Court decision at the Taiwan High Court. The Taiwan High Court held three pre-trial hearings in 2008, and three pre-trial hearings and three trial hearings
in 2009. Due to the rotation of the judges in the meantime, a new bench was formed at the beginning of 2010 to try this case. As of March 31, 2010, no trial schedule has been set since the new bench took over this case.

Theoretically, as a result of prosecutors appeal, Mr. Cheng may still be convicted of one or more charges in the indictment. In
addition, new evidence that leads to additional criminal charges and/or an adverse judgment against Mr. Cheng may be produced during the ongoing criminal investigation, and the special committee may make recommendations to our board in respect
of Mr. Chengs positions with us or our subsidiaries. However, up to the present, no new evidence or charge has been presented or collected by the prosecutor or the Court. Therefore, we are reasonably confident that the non-guilty judgment
for Mr. Cheng will be maintained by the Taiwan High Court. If Mr. Cheng is convicted, or in light of any new developments, the special committee may recommend or our board of directors may otherwise decide that it is in the Companys
best interests that Mr. Cheng no longer serves in all or some of his current capacities with us or our subsidiaries, or if Mr. Cheng resigns as a result of a final adverse judgment rendered against him by the court, or otherwise, the
public perception of us may be seriously harmed and we would lose some or all of the services of Mr. Cheng. In addition, if Mr. Cheng is convicted and sentenced to imprisonment, the ROC Financial Supervisory Commission may subject ChipMOS
Taiwan or ThaiLin to certain restrictions on financing activities if Mr. Cheng continues to serve as the chairman or president of ChipMOS Taiwan or ThaiLin. Mr. Cheng is very important to our current on-going business operations and our
relationships with our customers and financing sources, and our loss of his services due to and any adverse publicity from the trial or conviction of Mr. Cheng or other key personnel could materially and adversely affect our business,
reputation and prospects and therefore cause our stock price to decline.

We depend on key customers for a substantial portion of our net revenue and a loss of, or
deterioration of the business from, or delayed payment by, any one of these customers could result in decreased net revenue and materially adversely affect our results of operations and financial condition.

We depend on a small group of customers for a substantial portion of our business. In 2009, our five largest customers, collectively
accounted for 51% of our net revenue. As part of our strategy, we have been focusing on sales to key customers through long-term service agreements. Beginning in 2008, we also resumed a focus on our business with smaller customers and customers who
do not place orders on a regular basis. We expect that we will continue to depend on a relatively limited number of customers for a significant portion of our net revenue, even as we increase the volume of our business with smaller customers and
customers who do not place orders on a regular basis. Any adverse development in our key customers operations, competitive position or customer base could materially reduce our net revenue and adversely affect our business and profitability.

ProMOS is an affiliate of Mosel, which, as of March 31, 2010, indirectly owned approximately 12.3% of our outstanding
common shares. In March 2008, ProMOS defaulted on its payment obligations under the long-term service agreement. In November 2008, we entered into a revised subcontracting contract with ProMOS by requiring ProMOS to provide wafers with a value of
80% of the subcontracting fee as collateral. Effective March 2009, we started to request prepayments from ProMOS. In May 2009, a further revised subcontracting contract was entered into by and between us and ProMOS under which ProMOS provided us
with wafer as a pledge for its payment obligations and Work-In-Process, or WIP and existing finished goods would serve as lien material. Part of ProMOS receivables had been recovered through sales of the pledged wafer and lien material back to
ProMOS with a discount to market price, and the remaining outstanding accounts receivables have been secured by equipment mortgage under the same contract arrangement. See Item 4. Information on the CompanyCustomers.

In January 2009, Spansion has defaulted on its payment obligations under the long-term service agreement and we have subsequently
terminated the long-term service agreement with Spansion on February 19, 2009. On March 1, 2009, Spansion has filed for a voluntary petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code. On January 25, 2010, ChipMOS
Taiwan entered into a Transfer of Claim Agreement to sell to Citigroup Financial Products Inc. (Citigroup) the general unsecured claim reflected in the proof of claim against Spansion filed by ChipMOS Taiwan in U.S. Bankruptcy Court. In
February 2010, we received payment of approximately US$33 million from an escrow agent for the sale of accounts receivable for testing and assembly services provided to Spansion in the amount of approximately US$66 million to US$70 million, which
was based on the Transfer of Claim Agreement. See Item 4. Information on the Company Customers.

Since
semiconductor companies generally rely on service providers with whom they have established relationships to meet their testing and assembly needs for their applications and new customers usually require us to pass a lengthy and rigorous
qualification process, if we lose any of our key customers, we may not be able to replace them in a timely manner. We cannot assure you that receivable collection difficulties experienced by us will not occur in the future. If any of our key
customers reduces or cancels its orders or terminates existing contractual arrangements, and if we are unable to attract new customers and establish new contractual arrangements with existing or new customers, our net revenue could be reduced and
our business and results of operations may be materially adversely affected.

Because of our high fixed costs, if we are unable to achieve relatively high capacity utilization
rates, our earnings and profitability may be adversely affected.

Our operations are characterized by a high
proportion of fixed costs. For memory and logic/mixed-signal semiconductor testing services, our fixed costs represented 75%, 79% and 88% of our total cost of revenue in 2007, 2008 and 2009, respectively. For memory and logic/mixed-signal
semiconductor assembly services, our fixed costs represented 24%, 30% and 31% of our total cost of revenue in 2007, 2008 and 2009, respectively. For LCD and other flat-panel display driver semiconductor testing and assembly services, our fixed costs
represented 54%, 57% and 56% of our total cost of revenue in 2007, 2008 and 2009, respectively. Our profitability depends in part not only on absolute pricing levels for our services, but also on the utilization rates for our testing and assembly
equipment, commonly referred to as capacity utilization rates. Increases or decreases in our capacity utilization rates can significantly affect our gross margins as unit costs generally decrease as the fixed costs are allocated over a
larger number of units. In the past, our capacity utilization rates have fluctuated significantly as a result of the fluctuations in the market demand for semiconductors. If we fail to increase or maintain our capacity utilization rates, our
earnings and profitability may be adversely affected. In addition, we have entered into various long-term assembly and testing services agreements with certain of our customers that may require us to incur significant capital expenditures. If we are
unable to achieve high capacity utilization rates for the equipment purchased pursuant to these agreements, our gross margins may be materially and adversely affected.

The testing and assembly process is complex and our production yields and customer relationships may suffer as a result of defects or malfunctions
in our testing and assembly equipment and the introduction of new packages.

Semiconductor testing and assembly are
complex processes that require significant technological and process expertise. Semiconductor testing involves sophisticated testing equipment and computer software. We develop computer software to test our customers semiconductors. We also
develop conversion software programs that enable us to test semiconductors on different types of testers. Similar to most software programs, these software programs are complex and may contain programming errors or bugs. In addition, the
testing process is subject to human error by our employees who operate our testing equipment and related software. Any significant defect in our testing or conversion software, malfunction in our testing equipment or human error could reduce our
production yields and damage our customer relationships.

The assembly process involves a number of steps, each of which must
be completed with precision. Defective packages primarily result from:



| |  |  | contaminants in the manufacturing environment;
| | - |  | ----------------------------------------------



| |  |  | human error;
| | - |  | ------------



| |  |  | equipment malfunction;
| | - |  | ----------------------



| |  |  | defective raw materials; or
| | - |  | ---------------------------



| |  |  | defective plating services.
| | - |  | ---------------------------

These and other factors have, from time to time, contributed to lower production yields. They may do so in the future, particularly as we
expand our capacity or change our processing steps. In addition, to be competitive, we must continue to expand our offering of packages. Our production yields on new packages typically are significantly lower than our production yields on our more
established packages. Our failure to maintain high standards or acceptable production yields, if significant and prolonged, could result in a loss of customers, increased costs of production, delays, substantial amounts of returned goods and related
claims by customers. Further, to the extent our customers have set target production yields, we may be required to compensate our customers in a pre-agreed manner. Any of these problems could materially adversely affect
our business reputation and result in reduced net revenue and profitability.

Because of the highly cyclical nature of our industry, our
capital requirements are difficult to plan. If we cannot obtain additional capital when we need it, we may not be able to maintain or increase our current growth rate and our profits will suffer.

As our industry is highly cyclical and rapidly changing, our capital requirements are difficult to plan. To remain competitive, we may
need capital to fund the expansion of our facilities as well as to fund our equipment purchases and research and development activities. To meet our liquidity, capital spending and other capital needs, we have taken and plan to take certain measures
to generate additional working capital and to save cash. See Item 5. Operating and Financial Review and ProspectsLiquidity and Capital Resources.

##### Table of Contents

In addition, future capacity expansions or market or other developments may require
additional funding. Our ability to obtain external financing in the future depends on a number of factors, many of which are beyond our control. They include:



| |  |  | our future financial condition, results of operations and cash flows;
| | - |  | ---------------------------------------------------------------------



| |  |  | general market conditions for financing activities by semiconductor testing and assembly companies; and
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | economic, political and other conditions in Taiwan and elsewhere.
| | - |  | -----------------------------------------------------------------

If we are unable to obtain funding in a timely manner or on acceptable terms, our growth prospects and potential future profitability
will suffer.

Disputes over intellectual property rights could be costly, deprive us of technologies necessary for us to stay
competitive, render us unable to provide some of our services and reduce our opportunities to generate revenue.

Our
ability to compete successfully and achieve future growth will depend, in part, on our ability to protect our proprietary technologies and to secure, on commercially acceptable terms, critical technologies that we do not own. We cannot assure you
that we will be able to independently develop, or secure from any third party, the technologies required for our testing and assembly services. Our failure to successfully obtain these technologies may seriously harm our competitive position and
render us unable to provide some of our services.

Our ability to compete successfully also depends on our ability to operate
without infringing upon the proprietary rights of others. The semiconductor testing and assembly industry is characterized by frequent litigation regarding patent and other intellectual property rights. We may incur legal liabilities if we infringe
upon the intellectual property or other proprietary rights of others. The situation is exacerbated by our inability to ascertain what patent applications have been filed in the United States or elsewhere until they are granted. If any third party
succeeds in its intellectual property infringement claims against us or our customers, we could be required to:



| |  |  | discontinue using the disputed process technologies, which would prevent us from offering some of our testing and assembly services;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | pay substantial monetary damages;
| | - |  | ---------------------------------



| |  |  | develop non-infringing technologies, which may not be feasible; or
| | - |  | ------------------------------------------------------------------



| |  |  | acquire licenses to the infringed technologies, which may not be available on commercially reasonable terms, if at all.
| | - |  | -----------------------------------------------------------------------------------------------------------------------

Any one of these developments could impose substantial financial and administrative burdens on us and hinder our business. We are, from
time to time, involved in litigation in respect of intellectual property rights. Any litigation, whether as plaintiff or defendant, is costly and diverts our resources. If we fail to obtain necessary licenses on commercially reasonable terms or if
litigation, regardless of the outcome, relating to patent infringement or other intellectual property matters occurs, our costs could be substantially increased to impact our margins. Any such litigation could also prevent us from testing and
assembling particular products or using particular technologies, which could reduce our opportunities to generate revenue. For more information on litigation in respect of intellectual property rights, see Item 8. Financial
InformationLegal Proceedings.

If we are unable to obtain raw materials and other necessary inputs from our suppliers in a
timely and cost-effective manner, our production schedules would be delayed and we may lose customers and growth opportunities and become less profitable.

Our operations require us to obtain sufficient quantities of raw materials at acceptable prices in a timely and cost-effective manner. We
source most of our raw materials, including critical materials like leadframes, organic substrates, epoxy, gold wire and molding compound for assembly, and tapes for TCP/COF, from a limited group of suppliers. We purchase all of our materials on a
purchase order basis and have no long-term contracts with any of our suppliers. From time to time, suppliers have extended lead times, increased the price or limited the supply of required materials to us because of market shortages. Consequently,
we may, from time to time, experience difficulty in obtaining sufficient quantities of raw materials on a timely basis. In addition, from time to time, we may reject materials that do not meet our specifications, resulting in declines in output or
yield. Although we typically maintain at least two suppliers for each key raw material, we cannot assure you that we will be able to obtain sufficient quantities of raw materials and other supplies of an acceptable quality in the future. It usually
takes from three to six months to switch from one supplier to another, depending on the complexity of the raw material. If we are unable to obtain raw materials and other necessary inputs in a timely and cost-effective manner, we may need to delay
our production and delivery schedules, which may result in the loss of business and growth opportunities and could reduce our profitability.

If we are unable to obtain additional testing and assembly equipment or facilities in a timely manner
and at a reasonable cost, we may be unable to fulfill our customers orders and may become less competitive and less profitable.

The semiconductor testing and assembly business is capital intensive and requires significant investment in expensive equipment
manufactured by a limited number of suppliers. The market for semiconductor testing and assembly equipment is characterized, from time to time, by intense demand, limited supply and long delivery cycles. Our operations and expansion plans depend on
our ability to obtain equipment from a limited number of suppliers in a timely and cost-effective manner. We have no binding supply agreements with any of our suppliers and we acquire our testing and assembly equipment on a purchase order basis,
which exposes us to changing market conditions and other significant risks. Semiconductor testing and assembly also requires us to operate sizeable facilities. If we are unable to obtain equipment or facilities in a timely manner, we may be unable
to fulfill our customers orders, which could negatively impact our financial condition and results of operations as well as our growth prospects. Under our long-term service agreement we have entered into with Spansion in September 2005, we
have committed to acquire certain wafer sorting testers and probers. Spansion has defaulted on its payment obligations under the long-term service agreement and we have subsequently terminated the long-term service agreement with Spansion on
February 19, 2009. Currently, we do not have any other long-term service agreements that require our commitment to acquire additional testing and assembly equipment or facilities, however we can not assure you that such commitment will not be
made in the future. See Item 4. Information on the Company Customers.

If we are unable to manage the expansion of our
operations and resources effectively, our growth prospects may be limited and our future profitability may be reduced.

We expect to continue to expand our operations and increase the number of our employees. Rapid expansion puts a strain on our managerial,
technical, financial, operational and other resources. As a result of our expansion, we will need to implement additional operational and financial controls and hire and train additional personnel. We cannot assure you that we will be able to do so
effectively in the future, and our failure to do so could jeopardize our expansion plans and seriously harm our operations.

Bermuda law
may be less protective of shareholder rights than laws of the United States or other jurisdictions.

Our corporate
affairs are governed by our memorandum of association, our bye-laws and laws governing corporations incorporated in Bermuda. Shareholder suits such as class actions (as these terms are understood with respect to corporations incorporated in the
United States) are generally not available in Bermuda. Therefore, our shareholders may be less able under Bermuda law than they would be under the laws of the United States or other jurisdictions to protect their interests in connection with actions
by our management, members of our board of directors or our controlling shareholder.

It may be difficult to bring and enforce suits
against us in the United States.

We are incorporated in Bermuda and a majority of our directors and most of our
officers are not residents of the United States. A substantial portion of our assets is located outside the United States. As a result, it may be difficult for our shareholders to serve notice of a lawsuit on us or our directors and officers
within the United States. Because most of our assets are located outside the United States, it may be difficult for our shareholders to enforce in the United States judgments of United States courts. Appleby, our Bermuda counsel, has advised us that
there is some uncertainty as to the enforcement in Bermuda, in original actions or in actions for enforcement of judgments of United States courts, of liabilities predicated upon United States federal securities laws.

Investor confidence and the market price of our common shares may be adversely impacted if we or our
independent public registered accounting firm is unable to conclude that our internal control over our financial reporting is effective as required by Section 404 of the Sarbanes-Oxley Act of 2002.

We are subject to the SECs reporting obligations, and beginning in our Annual Report on Form 20-F for the year ended
December 31, 2006, we have been required by the SEC, as directed by Section 404 of the Sarbanes-Oxley Act of 2002, to include a report of management on our internal control over financial reporting in our Annual Report on Form 20-F that
contains an assessment by management of the effectiveness of our internal control over financial reporting. Beginning in fiscal year 2007, our independent public registered accounting firm has audited the effectiveness of our internal control over
financial reporting. Although our management concluded that our internal controls are effective in this Annual Report on Form 20-F, and our independent public registered accounting firm has rendered its opinion that we maintained, in all material
respects, effective internal control over financial reporting as of December 31, 2009, based on criteria set forth in Internal Control  Integrated Framework issued by the Treadway Commission (COSO), our management may not conclude that
our internal controls are effective in the future. Moreover, even if our management concludes that our internal controls over our financial reporting are effective, our independent public registered accounting firm may disagree. If our independent
public registered accounting firm is not satisfied with our internal controls over our financial reporting or the level at which our controls are documented, designed, operated or reviewed, or if the independent public registered accounting firm
interprets the requirements, rules or regulations differently from us, it may decline to attest to our managements assessment or may issue an adverse opinion in the future. Any of these possible outcomes could result in an adverse reaction in
the financial marketplace due to a loss of investor confidence in the reliability of our consolidated financial statements, which ultimately could negatively impact the market prices of our common shares.

Any environmental claims or failure to comply with any present or future environmental regulations, or any new environmental regulations, may
require us to spend additional funds, may impose significant liability on us for present, past or future actions, and may dramatically increase the cost of providing our services to our customers.

We are subject to various laws and regulations relating to the use, storage, discharge and disposal of chemical by-products of, and water
used in, our assembly and gold bumping processes. Although we have not suffered material environmental claims in the past, a failure or a claim that we have failed to comply with any present or future regulations could result in the assessment of
damages or imposition of fines against us, suspension of production or a cessation of our operations or negative publicity. New regulations could require us to acquire costly equipment or to incur other significant expenses. Any failure on our part
to control the use of, or adequately restrict the discharge of, hazardous substances could subject us to future liabilities that may materially reduce our earnings.

Fluctuations in exchange rates could result in foreign exchange losses.

Currently, most of our net revenue is denominated in NT dollars. Our cost of revenue and operating expenses, on the other hand, are
incurred in several currencies, including NT dollars, Japanese yen, US dollars and Renminbi, or RMB. In addition, a substantial portion of our capital expenditures, primarily for the purchase of testing and assembly equipment, has been, and is
expected to continue to be, denominated in Japanese yen with much of the remainder in US dollars. We also have debt denominated in NT dollars, Japanese yen, US dollars and RMB. Fluctuations in exchange rates, primarily among the US dollar, the
NT dollar and the Japanese yen, will affect our costs and operating margins in NT dollar terms. In addition, these fluctuations could result in exchange losses and increased costs in NT dollar terms. Despite selective hedging and other techniques
implemented by us, fluctuations in exchange rates have affected, and may continue to affect, our financial condition and results of operations.

We may not be successful in our acquisitions, investments, joint ventures and dispositions, and may therefore be unable to implement fully our
business strategy.

As part of our growth strategy, we may make acquisitions and investments in companies and
businesses, establish joint ventures or make dispositions of our interests. For example, on November 21, 2005, we merged Chantek into ChipMOS Taiwan, and on December 1, 2005, we merged ChipMOS Logic TECHNOLOGIES INC., or ChipMOS Logic,
into ThaiLin Semiconductor Corp., or ThaiLin. In November 2004, we acquired certain testing and assembly equipment from First International Computer Testing and Assembly, or FICTA, as well as a 67.8% stake in First Semiconductor Technology Inc.,
which interest we transferred to First Semiconductor Technology Inc. in April 2005 for approximately US$2 million. In September 2007, we acquired all outstanding common shares of ChipMOS Taiwan through a share exchange transaction with ChipMOS
Taiwan. In February 2010, we agreed to sell approximately 15.8% of ChipMOS Taiwans outstanding shares to Siliconware Precision. The success of our acquisitions, investments, joint ventures and dispositions depends on a number of factors,
including:



| |  |  | our ability to identify suitable investment, acquisition, joint venture or disposition opportunities;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | our ability to reach an agreement for an acquisition, investment, joint venture or disposition opportunity on terms that are satisfactory to us or at
all;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | the extent to which we are able to exercise control over the acquired or joint venture company;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | our ability to align the economic, business or other strategic objectives and goals of the acquired company with those of our company; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to successfully integrate the acquired or joint venture company or business with our company.
| | - |  | ---------------------------------------------------------------------------------------------------------

If we are unsuccessful in our acquisitions, investments, joint ventures and dispositions, we may not be able to implement fully our
business strategy to maintain or grow our business.

We depend on key personnel, and our revenue could decrease and our costs could
increase if we lose their services.

We depend on the continued service of our executive officers and skilled
engineering, technical and other personnel. We will also be required to hire a substantially greater number of skilled employees in connection with our expansion plans. In particular, we depend on a number of skilled employees in connection with our
LCD and other flat-panel display driver semiconductor testing and assembly services, and the competition for such employees in Taiwan and Mainland China is intense. We may not be able to either retain our present personnel or attract additional
qualified personnel as and when needed. Moreover, we do not carry key person insurance for any of our executive officers nor do we have employment contracts with any of our executive officers or employees, and, as a result, none of our executive
officers or employees is bound by any non-competition agreement. If we lose any of our key personnel, it could be very difficult to find and integrate replacement personnel, which could affect our ability to provide our services, resulting in
reduced net revenue and earnings. In addition, we may need to increase employee compensation levels in order to retain our existing officers and employees and to attract additional personnel. As of March 31, 2010, 11.4% of the workforce at our
facilities are foreign workers employed by us under work permits that are subject to government regulations on renewal and other terms. Consequently, if the regulations in Taiwan relating to the employment of foreign workers were to become
significantly more restrictive or if we are otherwise unable to attract or retain these workers at reasonable cost, we may be unable to maintain or increase our level of services and may suffer reduced net revenue and earnings.

Risk Relating to Our Relationship with Mosel

ChipMOS Taiwan entered into certain transactions that, if determined to have constituted impermissible financings or purchases of assets or equity
of Mosel under ROC law, could result in the resignations of members of our management. As a result, our business operations could be disrupted and the market price of our common shares could decline.

ROC law limits the ability of a company incorporated in Taiwan to purchase any equity interest in companies, directly or indirectly,
holding more than 50% of its issued and outstanding voting securities or registered capital or to provide loans or other financing to any company. ChipMOS Taiwan purchased NT$242 million worth of Mosel shares in 2002. Lee and Li, our ROC special
counsel, has advised us that these purchases do not violate relevant ROC law that prohibits a subsidiary from buying or taking collateral in shares of companies holding, directly or indirectly, more than 50% of its issued and outstanding voting
securities or registered capital, because Mosels indirect interest (calculated as the product of (i) Mosels percentage interest in ChipMOS Bermuda and (ii) ChipMOS Bermudas percentage interest in ChipMOS Taiwan) in
ChipMOS Taiwan was less than 50% and ChipMOS Bermuda is incorporated outside of Taiwan. In 2005, ChipMOS Taiwan disposed of NT$84 million of Mosel shares, and in August 2006, ChipMOS Taiwan further disposed of the remaining Mosel shares for
approximately NT$30 million. ChipMOS Taiwan no longer owns any Mosel shares. Lee and Li has advised that under relevant ROC law, there is no similar restriction or limitation on a subsidiarys disposal of its parents equity shares, if the
previous acquisitions of such shares complied with relevant ROC law. However, we understand that there is no applicable judicial precedent and there is some doubt as to how a court would rule if presented with the situation.

If it were to be determined that any of the transactions described above constituted an impermissible financing or purchase of assets of
Mosel by ChipMOS Taiwan or an impermissible purchase of Mosels equity by ChipMOS Taiwan, then ChipMOS Taiwans then chairman and any responsible officers would be jointly and severally liable to ChipMOS Taiwan for any losses suffered by
ChipMOS Taiwan and may also be severally liable criminally for any breach of fiduciary duties that resulted in losses and damages suffered by ChipMOS Taiwan. Moreover, certain of these transactions may not have been in full compliance with ChipMOS
Taiwans then applicable internal procedures due to the failure to have received an appropriate valuation opinion prior to entering into such purchases. The failure to comply fully with ChipMOS Taiwans then applicable internal procedures
could constitute evidence of a failure by the then chairman of ChipMOS Taiwan and responsible officers to comply fully with their fiduciary duties, which could result in them being held criminally liable for any breach of fiduciary duties that
resulted in losses and damages to ChipMOS Taiwan. If members of our current management were held to have breached their fiduciary duties or become criminally liable for the transactions described above, they may become obliged, whether under law or
otherwise, to resign from their respective positions at ChipMOS Bermuda and our affiliates. Any loss of the services of these persons could disrupt our business, damage our reputation, and cause the market price of our common shares to decline.

Risks Relating to Countries in Which We Conduct Operations

The investment in Mainland China by our controlled consolidated subsidiary, Modern Mind, through ChipMOS Shanghai, and the related contractual
arrangements may result in Mosel or Siliconware Precision violating ROC laws governing investments in Mainland China by ROC companies or persons. Any sanctions on Mosel or Siliconware Precision as a result of any violation of ROC laws may cause
Mosel or Siliconware Precision to decrease its ownership in us significantly or cause Mosel or Siliconware Precision to take other actions that may not be in the best interest of our other shareholders.

Previously, ROC laws and regulations generally prohibited investment by ROC entities in Mainland China in most aspects of the
semiconductor testing and assembly industry. In February 2010, these restrictions have been relaxed. ROC entities now may make investment in Mainland China in the semiconductor testing and assembly industry if they have obtained approval from the
Investment Commission of the ROC Ministry of Economic Affairs, or the Investment Commission. The Investment Commission will undertake a special approval process if the investment amount exceeds US$50,000,000. Investment is defined for
this purpose to mean:



| |  |  | establishing a new company or enterprise in Mainland China;
| | - |  | -----------------------------------------------------------



| |  |  | increasing ones equity interest in an existing company or enterprise in Mainland China;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | acquiring shares in an existing company or enterprise in Mainland China (other than shares of publicly traded companies, acquisition of which is
prohibited under current policy of the Investment Commission); or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | establishing or expanding a branch office in Mainland China.
| | - |  | ------------------------------------------------------------

We provide our services in Mainland China through ChipMOS Shanghai, a company incorporated under the laws of the PRC and a wholly-owned
subsidiary of Modern Mind. Modern Mind is a company incorporated under the laws of the British Virgin Islands and is wholly-owned by Jesper Limited, a company incorporated under the laws of the British Virgin Islands. While we do not own any equity
interest in Modern Mind, we control Modern Mind through our ownership of a demand note issued by Modern Mind, convertible into common shares with a controlling equity interest in Modern Mind at a conversion rate of one common share of Modern Mind
for every US$1.00 if repayment is not made when due. Under accounting principles that are applicable to us, Modern Mind is our controlled consolidated subsidiary. In addition, we have obtained from Jesper Limited an irrevocable option to acquire the
common shares of Modern Mind then owned by Jesper Limited. Payment under the demand notes is fully and unconditionally guaranteed by Jesper Limited and secured by a pledge agreement in respect of the entire equity interest in Modern Mind and ChipMOS
Shanghai. We have also entered into other contractual arrangements with regard to ChipMOS Shanghai. For more information, see Item 4. Information on the CompanyOur Structure and HistoryMODERN MIND TECHNOLOGY LIMITED and ChipMOS
TECHNOLOGIES (Shanghai) LTD.

As the regulations described above are applicable only to entities organized within the
ROC with respect to specified investments in Mainland China made by these entities, in the opinion of Lee and Li, our ROC special counsel, ChipMOS Bermudas indirect control over ChipMOS Shanghai through the ownership of demand notes issued by
Modern Mind and the above contemplated contractual arrangements are in compliance with all existing ROC laws and regulations. There are, however, substantial uncertainties regarding the interpretation and application of ROC laws and regulations,
including the laws and regulations governing the enforcement and performance of our contractual arrangements. Accordingly, we cannot assure you that ROC regulatory authorities will not take a view contrary to the opinion of our ROC special counsel.

In addition, under current applicable ROC regulations, if a company incorporated in the ROC has directly or indirectly
invested in a company incorporated outside of the ROC and has controlling power over the management and operations of such non-ROC company, any investment by such non-ROC company in the PRC will constitute an investment by the controlling ROC
company that is subject to ROC laws and regulations. As a result, for the purposes of these regulations, any investment (within the meaning of the ROC laws governing investments in Mainland China) by ChipMOS Bermuda in ChipMOS Shanghai may be deemed
to be an investment in Mainland China by Mosel and/or Siliconware Precision, if Mosel and/or Siliconware Precision is determined to have controlling power over our management and operations. While the regulations do not define what constitutes
controlling power over management and operations, we understand from our ROC special counsel, Lee and Li, that, due to Mosels and/or Siliconware Precisions equity interest in us and representatives on our board of directors,
any conversion of the convertible notes or demand notes into shares of Modern Mind or other acquisition of shares of Modern Mind or ChipMOS Shanghai by ChipMOS Bermuda may be deemed an investment in Mainland China by Mosel and/or Siliconware
Precision and require approval of the Investment Commission, and be subject to the prohibitions described in the first paragraph of this risk factor analysis. As a result, so long as Mosel and/or Siliconware Precision is deemed to have controlling
power over ChipMOS Bermudas management and operations, ChipMOS Bermuda may have to choose not to convert its convertible notes or demand notes into common shares of Modern Mind in order to avoid any violations by Mosel and/or Siliconware
Precision under these regulations. As a result, any significant ownership of our common shares by Mosel and/or Siliconware Precision could materially and adversely restrict our ability and flexibility in structuring our investment in Mainland China
and thereby affect our business prospects.

If Mosel or Siliconware Precision was found to be in violation of the applicable ROC laws
and regulations governing investments in Mainland China, Mosel or Siliconware Precision may be ordered by the Investment Commission to cease such investment activities in Mainland China within a specified period of time and may be subject to a fine
of between NT$50,000 and NT$25,000,000. In such case, Mosel or Siliconware Precision may comply with the order of the Investment Commission either by causing us to terminate our investment activities in Mainland China or by taking actions that will
cause Mosel or Siliconware Precision to cease having controlling power over our management and operations. If Mosel or Siliconware Precision fails to comply with the order of the Investment Commission, the ROC government can impose on the chairman
of Mosel or Siliconware Precision up to two years imprisonment, a fine of up to NT$25 million, or both. We cannot provide any assurance that any actions taken by Mosel or Siliconware Precision in response to any orders by the Investment
Commission will be in the best interest of our other shareholders. Any termination or disposal of ChipMOS Shanghais operations in Mainland China could have a material adverse effect on our financial condition, results of operations or
prospects, as well as the market price of our common shares.

ROC laws and regulations limit or prohibit certain technology cooperation
between ROC persons or entities with PRC persons or entities, and our current technology transfer arrangements between ChipMOS Bermuda and ChipMOS Shanghai may be found to be in violation of any such limitation or prohibition, which may result in
the termination of such technology transfer arrangements and therefore have a material adverse effect on the operations of ChipMOS Shanghai and our financial condition and results of operations.

ROC laws and regulations previously prohibited any transfer of semiconductor testing and assembly technologies to any person or entity
located in Mainland China, except for transfers involving certain low-end semiconductor testing and assembly technologies, such as conventional wire bond assembly technology, if certain requirements are met. The ROC Ministry of Economic Affairs has
the ultimate administrative authority in interpreting such laws and regulations. In February 2010, these restrictions have been relaxed, so that ROC entities may transfer semiconductor testing and assembly technologies to any person or entity
located in Mainland China after they have obtained approval from the Investment Commission. Under a technology transfer agreement, dated August 1, 2002, ChipMOS Bermuda licensed to ChipMOS Shanghai certain testing and assembly-related
technologies that were then controlled by ChipMOS Bermuda, which included technologies that were licensed to ChipMOS Bermuda by ChipMOS Taiwan. ChipMOS Bermuda also provided ChipMOS Taiwan with technical support and consulting services under this
agreement. On April 7, 2004, ChipMOS Bermuda entered into an assignment agreement with ChipMOS Taiwan, pursuant to which ChipMOS Taiwan transferred all of the technologies it owned as of that date to ChipMOS Bermuda, including those previously
licensed to ChipMOS Bermuda. On April 12, 2007, ChipMOS Bermuda entered into an assignment agreement with ChipMOS Taiwan, pursuant to which ChipMOS Taiwan assigned and transferred fifty percent of the title to ownership of and interest in all
of the technologies and intellectual property it owned as of that date to ChipMOS Bermuda. ChipMOS Bermuda will continue to license such technologies to ChipMOS Shanghai pursuant to the above mentioned technology transfer agreement dated
August 1, 2002.

In the opinion of Lee and Li, our ROC special counsel, our technology transfer arrangements as described
above are in compliance with all applicable ROC laws and regulations. However, substantial uncertainties remain regarding the interpretation and application of those laws and regulations. Accordingly, we cannot assure you that ROC regulatory
authorities will not take a view contrary to the opinion of our ROC special counsel. If ChipMOS Taiwan were determined to be in violation of applicable ROC laws and regulations governing technology cooperation with PRC persons and entities, ChipMOS
Taiwan may be ordered by the Investment Commission to terminate such activity within a specified period of time and may be subject to a fine of between NT$50 thousand and NT$25 million. In addition, if ChipMOS Taiwan does not comply with the order
of the Investment Commission, the ROC government can impose on the chairman of ChipMOS Taiwan up to two years imprisonment, a fine of up to NT$25 million, or both. Any termination of our current technology transfer to ChipMOS Shanghai could
materially adversely affect our Mainland China operations and our financial condition, results of operations or prospects, as well as the market price of our common shares.

Our current ownership structure and contractual arrangements with Jesper Limited, Modern Mind and ChipMOS Shanghai may not be effective in
providing operational control of our Mainland China operations.

We provide our services in Mainland China through
ChipMOS Shanghai, a wholly-owned subsidiary of Modern Mind. While we do not own any equity interest in Modern Mind, we have a controlling interest in Modern Mind through our ownership of a demand note issued by Modern Mind. In 2004, we restructured
our control of ChipMOS Shanghai and the way we provide our services in Mainland China through contractual arrangements with Jesper Limited, Modern Mind, and ChipMOS Shanghai. These contractual arrangements, however, may not be as effective in
providing control over our Mainland China operations as would direct ownership in ChipMOS Shanghai. See  The investment in Mainland China by our controlled consolidated subsidiary, Modern Mind, through ChipMOS Shanghai, and the related
contractual arrangements may result in Mosel or Siliconware Precision violating ROC laws governing investments in Mainland China by ROC companies or persons. Any sanctions on Mosel or Siliconware Precision as a result of any violation of ROC laws
may cause Mosel or Siliconware Precision to decrease its ownership in us significantly or cause Mosel or Siliconware Precision to take other actions that may not be in the best interest of our other shareholders.

##### Table of Contents

Our ability to direct the operations we conduct through our subsidiaries and affiliated companies that
we do not fully own may be limited by legal duties owed to other shareholders of such companies.

Certain of our
operations are conducted through companies that we do not fully own. For example, certain current consolidated operations are conducted through ThaiLin, ChipMOS Taiwans 42.9% owned subsidiary as of March 31, 2010, and ChipMOS Shanghai, in
which we exercise control without holding any direct or indirect equity interest. We also conduct other activities through our affiliated entities.

In accordance with the various laws of the relevant jurisdictions in which our subsidiaries and affiliates are organized, each of our
subsidiaries and affiliates and their respective directors owe various duties to their respective shareholders. As a result, the actions we wish our subsidiaries or affiliates to take could be in conflict with their or their directors legal
duties owed to their other shareholders. When those conflicts arise, our ability to cause our subsidiaries or affiliates to take the action that we desire may be limited.

Any future outbreak of health epidemics and outbreaks of contagious diseases, including avian influenza, Severe Acute Respiratory Syndrome or H1N1
influenza may materially affect our operations and business.

An outbreak of a contagious disease such as avian
influenza, Severe Acute Respiratory Syndrome (SARS), or more recently, the New Influenza A (H1N1) or more commonly known as the swine flu, for which there is inadequate treatment or no known cure or vaccine, may potentially result in a
quarantine of infected employees and related persons, and adversely affect our operations at one or more of our facilities or the operations of our customers or suppliers. We cannot predict the impact that any future outbreak of these or other
diseases could have on our business and results of operations.

We face substantial political risk associated with doing business in
Taiwan, particularly due to recent domestic political events and the strained relations between the Republic of China and the Peoples Republic of China, that could negatively affect our business and the market price of our common shares.

Our principal executive offices and most of our testing and assembly facilities are located in Taiwan. As a result,
our business, financial condition and results of operations and the market price of our common shares may be affected by changes in ROC governmental policies, as well as social instability and diplomatic and social developments in or affecting
Taiwan which are beyond our control. For example, the ROC has a unique international political status. The PRC government regards Taiwan as a renegade province and does not recognize the legitimacy of the ROC. Although significant economic and
cultural relations have been strengthened in recent years between the ROC and the PRC, relations have often been strained. In March 2005, the PRC government enacted the Anti-Secession Law codifying its policy of retaining the right to
use military force to gain control over Taiwan, particularly under what it considers as highly provocative circumstances, such as a declaration of independence by Taiwan or the refusal by the ROC to accept the PRCs stated One China
policy. Past developments related to the interaction between the ROC and the PRC have on occasion depressed the market prices of the securities of Taiwanese or Taiwan-related companies, including our own. Relations between the ROC and the PRC
and other factors affecting military, political or economic conditions in Taiwan could have a material adverse effect on our financial condition and results of operations, as well as the market price and the liquidity of our common shares.

We are vulnerable to natural disasters and other events disruptive to our business and operations.

We currently provide most of our testing services through our facilities in the Hsinchu Industrial Park and the Hsinchu Science Park in
Taiwan and the Shanghai Qingpu Industrial Zone, and all of our assembly services through our facilities in the Southern Taiwan Science Park in Taiwan and the Shanghai Qingpu Industrial Zone. Significant damage or other impediments to these
facilities as a result of natural disasters, industrial strikes or industrial accidents could significantly increase our operating costs.

Taiwan is particularly susceptible to earthquakes and typhoons. For example, in late 1999, Taiwan suffered severe earthquakes that caused
significant property damage and loss of life, particularly in the central part of Taiwan. These earthquakes damaged production facilities and adversely affected the operations of many companies involved in the semiconductor and other industries. We
experienced NT$1 million in damages to our machinery and equipment, NT$6 million in damages to our facilities, NT$1 million in damages to our inventory and five days of delay in our production schedule as a result of these earthquakes.

In January and February 2008, certain parts of Mainland China, particularly in the southern,
central and eastern regions, experienced reportedly the most severe winter weather in the country in recent decades, which resulted in significant and extensive damages to factories, power lines, homes, automobiles, crops and other properties,
blackouts, transportation and communications disruptions and other losses in the affected areas. In addition, in May 2008, certain semiconductor companies with facilities in eastern Mainland China experienced production disruption reportedly due to
power stoppages caused by the failure of certain electricity supply system in the area where the plants are located. We cannot assure you that our facilities in the Shanghai Qingpu Industrial Zone will not be adversely affected by future snowstorms,
power shortages, earthquakes or other similar events.

In addition, the production facilities of many of our suppliers and
customers and providers of complementary semiconductor manufacturing services, including foundries, are located in Taiwan and Mainland China. If our customers are affected, it could result in a decline in the demand for our testing and assembly
services. If our suppliers and providers of complementary semiconductor manufacturing services are affected, our production schedule could be interrupted or delayed. As a result, a major earthquake, snowstorm, other natural disaster or other
disruptive event in Taiwan or Mainland China could severely disrupt the normal operation of business and have a material adverse effect on our financial condition and results of operations.

Risks Relating to Our Corporate Structure

Our ability to receive dividends and other payments from our subsidiaries may be restricted by commercial, statutory and legal restrictions, and
thereby materially adversely affect our ability to grow, fund investments, make acquisitions, pay dividends, repay or repurchase outstanding indebtedness and otherwise fund and conduct our business.

We are a holding company, and our most significant asset is our majority ownership interest in ChipMOS Taiwan. Although we control
ChipMOS Shanghai through Modern Mind, we do not hold any equity interest in these entities due to ROC regulatory restrictions on investments in Mainland China. As long as we do not hold any equity interest in these entities, we are not entitled to
any dividends distributed by these entities and our contractual arrangements may not effectively prevent these entities from declaring any dividends to their shareholders. Dividends we receive from our subsidiaries, if any, will be subject to
taxation.

The ability of our subsidiaries to pay dividends, repay intercompany loans from us or make other distributions to
us is restricted by, among other things, the availability of funds and the terms of various credit arrangements entered into by our subsidiaries, as well as statutory and other legal restrictions. In addition, although there are currently no foreign
exchange control regulations which restrict the ability of our subsidiaries located in Taiwan to distribute dividends to us, we cannot assure you that the relevant regulations will not be changed and that the ability of our subsidiaries to
distribute dividends to us will not be restricted in the future. A Taiwan company is generally not permitted to distribute dividends or to make any other distributions to shareholders for any year in which it did not have either earnings or retained
earnings (excluding reserves). In addition, before distributing a dividend to shareholders following the end of a fiscal year, the company must recover any past losses, pay all outstanding taxes and set aside 10% of its annual net income (less prior
years losses and outstanding taxes) as a legal reserve until the accumulated legal reserve equals its paid-in capital, and may set aside a special reserve.

In addition, PRC law requires that our PRC-incorporated subsidiary only distributes dividends out of its net income, if any, as
determined in accordance with PRC accounting standards and regulations. Under PRC law, it is also required to set aside at least 10% of its after-tax net income each year into its reserve fund until the accumulated legal reserve amounts to 50% of
its registered capital. PRC-incorporated companies are further required to maintain a bonus and welfare fund at percentages determined at their sole discretion. The reserve fund and the bonus and welfare fund are not distributable as dividends.
Moreover, a ROC-incorporated company is only able to declare dividends at its annual general meeting of shareholders, which cannot occur until after completion of its annual financial statements. Any limitation on dividend payments by our
subsidiaries could materially adversely affect our ability to grow, fund investments, make acquisitions, pay dividends, repay or repurchase outstanding indebtedness, and otherwise fund and conduct our business.

Siliconware Precision and Mosel, our two largest shareholders, have significant influence over our company and may cause us to take actions that
may not be, or refrain from taking actions that may be, in our best interest or the best interest of our other shareholders.

Siliconware Precision and Mosel directly and indirectly owned approximately 13.3% and 12.3% of our common shares as of March 31,
2010, respectively. As the two largest shareholders that own more than 10% of our common shares respectively, Siliconware Precision and Mosel have significant influence over all matters submitted to our shareholders for approval and other corporate
actions, such as:

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



| |  |  | timing and manner of dividend distributions;
| | - |  | --------------------------------------------

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



| |  |  | open market purchase programs or other purchases of our common shares.
| | - |  | ----------------------------------------------------------------------

Siliconware Precision and Mosels substantial interests in our company could also:



| |  |  | delay, defer or prevent a change in who controls us;
| | - |  | ----------------------------------------------------



| |  |  | discourage bids for our shares at a premium over the market price; and
| | - |  | ----------------------------------------------------------------------



| |  |  | adversely affect the market price of our common shares.
| | - |  | -------------------------------------------------------

In addition, one of our directors, Mr. Hsing-Ti Tuan, also acts as a director of ProMOS, a subsidiary of Mosel. As a result,
conflicts of interest between Mr. Tuans duty to us and ProMOS and/or Mosel may arise. For an example of such a conflict of interest, see  Risks Relating to Countries in Which We Conduct OperationsThe investment in
Mainland China by our controlled consolidated subsidiary, Modern Mind, through ChipMOS Shanghai, and the related contractual arrangements may result in Mosel or Siliconware Precision violating ROC laws governing investments in Mainland China by ROC
companies or persons. Any sanctions on Mosel or Siliconware Precision as a result of any violation of ROC laws may cause Mosel or Siliconware Precision to decrease its ownership in us significantly or cause Mosel or Siliconware Precision to take
other actions that may not be in the best interest of our other shareholders. We cannot give any assurances that when conflicts of interest arise, Mr. Tuan will act in our interests, or that conflicts of interest will be resolved in our
favor.

Moreover, because Siliconware Precision and Mosel have potential power to direct or influence our corporate actions,
we may be required to engage in transactions that may not be agreeable to our other shareholders or that may not be in the best interest of our other shareholders.

Our ability to make further investments in ChipMOS Taiwan may be dependent on regulatory approvals. If ChipMOS Taiwan is unable to receive the
equity financing it requires, its ability to grow and fund its operations may be materially adversely affected.

As
ChipMOS Taiwan is not a listed company, it generally depends on its shareholders, ChipMOS Bermuda and Siliconware Precision, to meet its equity financing requirements. Any capital contribution by us to ChipMOS Taiwan may require the approval of the
relevant ROC authorities. For example, any capital contribution by us to ChipMOS Taiwan will require the approval of the authorities of the Science Park Administration. We may not be able to obtain any such approval in the future in a timely manner,
or at all. If ChipMOS Taiwan is unable to receive the equity financing it requires, its ability to grow and fund its operations may be materially adversely affected.

Risks Relating to Our Common Shares

Volatility in the price of our common shares may result in shareholder litigation that could in turn result in substantial costs and a diversion of
our managements attention and resources.

The financial markets in the United States and other countries have
experienced significant price and volume fluctuations, and market prices of technology companies have been and continue to be extremely volatile. Volatility in the price of our common shares may be caused by factors outside of our control and may be
unrelated or disproportionate to our results of operations. In the past, following periods of volatility in the market price of a public companys securities, shareholders have frequently instituted securities class action litigation against
that company. Litigation of this kind could result in substantial costs and a diversion of our managements attention and resources.

Certain provisions in our constitutive documents and in our severance agreements with our executive officers make the acquisition of us by
another company more difficult and costly and therefore may delay, defer or prevent a change of control.

Our bye-laws
provide that our board of directors is divided into three classes of directors, each class to be re-elected only once every three years. As a result, shareholders would not generally be able to replace a majority of the directors until after two
annual general meetings. In addition, any extraordinary corporate transaction such as a merger, amalgamation or consolidation, or a sale or transfer of all or substantially all of our assets, cannot be done without the approval of shareholders
representing 70% of the total voting rights of all shareholders having the right to vote at such general meeting called to consider such extraordinary transaction. These provisions in our constitutive documents may increase the difficulty faced by a
party which seeks to acquire control of our board or to approve an extraordinary transaction.

##### Table of Contents

In 2007, we entered into change in control severance agreements with certain executive
officers pursuant to which we agreed to pay certain severance payments if a change in control event (as defined in the change in control severance agreements) occurs and the employment of such executive officer is terminated by our company other
than for cause or by such executive officer for good reasons within two years following the occurrence of the change in control event. These changes in control agreements may increase the cost of a party seeking to effect a change in control of our
company.

Future sales, pledge or issuance of common shares by us or our current shareholders could depress our share price and you may
suffer dilution.

Sales of substantial amounts of shares in the public market, the perception that future sales may
occur, or the pledge of a substantial portion of our common shares could depress the prevailing market price of our shares. As of March 31, 2010, we had approximately 91 million shares outstanding, including approximately 55 million
shares of which are freely tradable within the United States without restriction or further registration under the Securities Act. Siliconware Precision, Mosel, ThaiLin and DLS Capital Management, LLC, our four largest shareholders, owned
12,174,998, 11,194,644, 6,493,998 and 5,229,367 common shares as of March 31, 2010, respectively, representing in the aggregate of approximately 38.4% of our outstanding common shares. See Item 7. Major Shareholders and Related Party
Transactions  Major Shareholders. As of March 31, 2010, we had US$2 million in aggregate principal amount of the 2006 Notes outstanding and US$35 million in aggregate principal amount of the 2009 Notes outstanding (including US$19
million in aggregate principal amount held by ThaiLin, ChipMOS Taiwans 42.9% owned subsidiary), and US$5 million in aggregate principal amount of the 2010 Notes outstanding. The 2006 Notes are convertible into our common shares at the
conversion price of US$6.85 per share, and US$14 million in aggregate principal amount of the 2009 Notes, US$21 million in aggregate principal amount of the 2009 Notes and US$5 million in aggregate principal amount of the 2010 Notes are convertible
into our common shares at the conversion price of US$1.50 per share, US$1.25 per share and US$1.25 per share, respectively, in each case the conversion price may be subject to certain adjustments.

Mosel in the past decided to sell a significant portion of our common shares in order to raise funds. In June 2006, Mosel sold 6,956,522
common shares through its wholly-owned subsidiary, Giant Haven, under a shelf registration statement which has since expired. In addition, in March 2007, we issued 12,174,998 common shares pursuant to a share purchase and subscription agreement with
ChipMOS Taiwan and Siliconware Precision, and we entered into a registration rights agreement in March 2007 with Siliconware Precision, pursuant to which we granted to Siliconware Precision certain rights to require us to register these common
shares for sale under the Securities Act. In July 2007, Mosel sold 8,121,266 common shares through Giant Haven to ProMOS and Powertech Technology, and we then granted Giant Haven, ProMOS and Powertech Technology certain rights to require us to
register these common shares for sale under the Securities Act. For a shareholder that is not our affiliate these shares may be resold pursuant to Rule 144 after lapse of the applicable holding period. In 2008, ProMOS failed to meet its payment
obligations to ThaiLin. Subsequently in March 2009, ThaiLin acquired 4,060,633 common shares from ProMOS pursuant to its enforcement of the collateral under a Stock Pledge Agreement between ThaiLin and ProMOS dated December 3, 2008.
Furthermore, each of Siliconware Precision, Mosel and ThaiLin may be able to sell, in any three-month period, that number of those ChipMOS common shares that each of Siliconware Precision, Mosel and ThaiLin owns, as the case may be, up to the
greater of (i) one percent of our outstanding common shares or (ii) the average weekly trading volume of our common shares as reported on the NASDAQ Capital Market during the four calendar weeks prior to filing a notice under Rule 144(h)
for any such sales pursuant to Rule 144(e) under the Securities Act.

On September 14, 2007, ChipMOS Bermuda issued
604,124 common shares pursuant to a share exchange transaction with ChipMOS Taiwan, under which ChipMOS Bermuda exchanged one common share for every 8.4 ChipMOS Taiwan shares then outstanding. Following the completion of the share exchange
transaction, ChipMOS Taiwan became our wholly-owned subsidiary. In February 2010, we agreed to sell approximately 15.8% of ChipMOS Taiwans outstanding shares to Siliconware Precision. Upon completion of that share purchase transaction by March
2011, we will own approximately 84.2% of ChipMOS Taiwans outstanding shares. We plan to issue, from time to time, additional shares in connection with employee compensation and to finance possible future capital expenditures, investments or
acquisitions. See Item 6. Directors, Senior Management and EmployeesShare Option Plan and Share Appreciation Rights Plan for a discussion of the Share Option Plan that we have adopted for the benefit of all of our directors,
officers, employees and consultants. The issuance of additional shares may have a dilutive effect on other shareholders and may cause the price of our common shares to decrease.

In addition, the indictment relating to Mr. Hung-Chiu Hu alleges that embezzled funds were used in investments by PacMOS, which, as
of March 31, 2010, owned 3.5% of our outstanding common shares. As a result, PacMOS may be ordered by relevant authorities to dispose of its investments made with any embezzled funds, which may result in a sale of our shares by PacMOS. A sale
of a significant number of our shares by PacMOS or our other current shareholders could depress our share price.

Our outstanding convertible notes will likely dilute the ownership interest of existing shareholders.

As of March 31, 2010, we had approximately US$42 million of convertible notes outstanding. US$40 million in
aggregate principal amount of the notes are PIK notes, or payment in kind notes, that allow us to pay interest in cash or our common shares, or a combination thereof. These PIK notes have a maturity date in 2014 and 2015, with an
interest rate of 8% or 10%, and a conversion price of either US$1.25 or US$1.50 per share, subject to anti-dilution adjustments upon the occurrence of certain events. See Item 5. Operating and Financial Review and ProspectsLiquidity and
Capital ResourcesConvertible Notes for more detailed description of our outstanding convertible notes.

Generally,
the conversion of convertible notes will dilute the ownership interest of existing shareholders and could adversely affect the market price of our common shares. Even if convertible notes are not converted, their existence may encourage the short
selling of the common shares by the holders of the convertible notes as well as other market participants, depressing the price of our common shares.

The PIK notes that we have issued present a dilution risk. When we elect to pay interest in our common shares, as we have done previously
in respect of our PIK notes, the number of common shares that we issue is determined on the basis of the prevailing market price of our common shares. If our share price decreases, we will have to issue a greater number of common shares to pay the
interest due on our PIK notes, which in turn could further depress the price of our common shares. In addition, the terms of our PIK notes require us to pay an additional amount upon conversion equal to a make-whole amount relating to
the principal amount of the notes being converted. The make-whole amount is the amount of interest that would have accrued from the applicable conversion date, change of control repurchase date or redemption date, as the case may be, until the
stated maturity, discounted to present value using the published yield on U.S. treasury notes plus 50 basis points; provided that the additional 50 basis points is not added if the applicable treasury note rate is greater than two percent (2%). As
with interest payments under the PIK notes, the make-whole amount is payable in cash or common shares or a combination thereof. Given the difference between the high rate of interest payable on our PIK notes and the existing low yield of U.S.
treasuries, the make-whole amount payable in PIK notes, if converted at this time would be significant, and if we paid such make-whole amount using our common shares, this would significantly dilute the ownership interest of existing shareholders
and could adversely affect the market price of our common shares.

The issuance by us of additional convertible notes, and in
particular, PIK notes, could further dilute the ownership interest of existing shareholders.

If the trading price of our common shares
declines, we may face a limited public market for our common shares and reduced availability of future debt or equity financing.

Companies listed on the NASDAQ Stock Market (NASDAQ) are subject to delisting for, among other things, failure to maintain a
minimum closing bid price of $1.00 per share for 30 consecutive business days. Though we are in compliance with the NASDAQ Listing Rules as of the date of this filing, we were not in compliance with the minimum bid price requirement from
September 15, 2009 until May 5, 2010, when we regained compliance. During this time, we applied for, and NASDAQ approved, the transfer of our listing from NASDAQ Global Select Market to NASDAQ Capital Market. If the bid price of our common
stock falls below $1.00 per share for 30 consecutive business days again in the future, we may be subject to delisting. If our common shares are delisted from the NASDAQ Capital Market, our common shares would likely trade in the over-the-counter
market, which could make selling our common shares more difficult. Smaller quantities of shares would likely be bought and sold, transactions could be delayed, and security analysts coverage of us may be reduced. In addition, in the event our
common shares are delisted, broker-dealers have certain regulatory burdens imposed upon them, which may discourage broker-dealers from effecting transactions in our common shares. These factors could limit our common shares liquidity and
result in lower prices and larger spreads in the bid and ask prices for our common shares.

Future declines in our share price
could also significantly impair our ability to raise additional necessary capital through equity or debt financing, and could significantly increase ownership dilution to shareholders caused by our issuing equity in financing or other transactions.
A general permission under the Exchange Control Act 1972 and the Exchange Control Regulation 1973 (and other relevant legislations and regulations) has been given by the Bermuda Monetary Authority (the BMA) for the issue and transfer of
our common shares, notes and other securities to and between non-residents of Bermuda for exchange control purposes, provided that our common shares remain listed on an appointed stock exchange (which includes listing on the NASDAQ Capital Market).
There can be no assurance that the BMA will give the same or a similar consent in the event our common shares are no longer listed on the NASDAQ Capital Market or another appointed stock exchange. In the absence of such a general consent, specific
consents of the BMA would be required for all issues and transfers of our shares, notes and other securities, unless such issues and/or transfers fall under certain exemptions as provided by the BMA.

Below is a description of our principal consolidated subsidiaries:

ChipMOS TECHNOLOGIES INC. ChipMOS Taiwan was incorporated in Taiwan in July 1997 as a joint venture company of Mosel and
Siliconware Precision and with the participation of other investors. Its operations consist of the testing and assembly of semiconductors as well as gold bumping and memory module manufacturing. We acquired our interest in ChipMOS Taiwan by issuing
our common shares to ChipMOS Taiwans shareholders in exchange for their 70.3% shareholding in ChipMOS Taiwan in January 2001. In October 2001, ChipMOS Taiwan issued 6,911,732 common shares as employee bonuses. In December 2002, we issued
531,175 common shares in exchange for 5,633,442 ChipMOS Taiwan common shares held by these employees.

On June 16, 2005,
ChipMOS Taiwan and Chantek, a 68.0% subsidiary of ChipMOS Taiwan, agreed to merge in a stock-for-stock transaction. Under the merger agreement, as amended on September 2, 2005, shareholders of Chantek (other than ChipMOS Taiwan) were entitled
to elect to receive cash or ChipMOS Taiwan shares in exchange for their Chantek shares at the ratio of 3.6 to 1. As a result, ChipMOS Taiwan paid NT$81 million in cash and issued 6 million (which represented approximately 0.7% of ChipMOS
Taiwans outstanding shares immediately after the completion of the transaction) shares to Chantek shareholders pursuant to the merger agreement. The transaction closed on November 21, 2005.

On March 27, 2007, we completed a share purchase and subscription transaction with ChipMOS Taiwan and Siliconware Precision, under
which we and ChipMOS Taiwan purchased all of Siliconware Precisions equity interest in ChipMOS Taiwan, and Siliconware Precision subscribed to 12,174,998 of our newly issued common shares through a private placement. As of March 31, 2007,
we held 99.1% of the outstanding common shares of ChipMOS Taiwan.

On September 14, 2007, we completed a share exchange
transaction with ChipMOS Taiwan pursuant to which we exchanged one common share for every 8.4 ChipMOS Taiwan shares. In connection with the share exchange transaction, ChipMOS Bermuda and ChipMOS Taiwan paid in the aggregate NT$53 million in
cash to purchase fractional shares and shares held by dissenting shareholders, and ChipMOS Bermuda issued 604,124 new common shares. Following the completion of the share exchange transaction, ChipMOS Taiwan became our wholly-owned subsidiary. In
February 2010, we agreed to sell approximately 15.8% of ChipMOS Taiwans outstanding shares to Siliconware Precision. Upon completion of that share purchase transaction by March 2011, we will own approximately 84.2% of ChipMOS Taiwans
outstanding shares.

ChipMOS TECHNOLOGIES (H.K.) Limited ChipMOS Hong Kong (formerly ChipMOS Far East Limited)
was incorporated in Hong Kong in November 2002. It is engaged in semiconductor testing and assembly services and trading of spare parts and tools. Effective May 31, 2005, the name of ChipMOS Far East Limited was changed to ChipMOS TECHNOLOGIES
(H.K.) Limited. As of March 31, 2010, we held 100% of the outstanding common shares of ChipMOS Hong Kong.

MODERN
MIND TECHNOLOGY LIMITED and ChipMOS TECHNOLOGIES (Shanghai) LTD. Modern Mind was incorporated in the British Virgin Islands in January 2002. Modern Mind conducts its operations through ChipMOS Shanghai, a wholly-owned subsidiary incorporated
in Mainland China in June 2002. ChipMOS Shanghai is engaged in wafer testing and semiconductor assembly and testing. We acquired a 100% equity interest in Modern Mind on December 12, 2002, and then transferred it to Jesper Limited on
December 31, 2002. In 2003, we acquired from Jesper Limited a convertible note in the amount of US$37.5 million issued by Modern Mind that may be converted into a controlling equity interest in Modern Mind at a conversion rate of one ordinary
share of Modern Mind for every US$1.00 if the repayment is not made when due. In 2004, we restructured our control of ChipMOS Shanghai and our Mainland China operations. On July 29, 2004, we replaced the US$37.5 million convertible note
previously issued by Modern Mind in its entirety with a US$62.8 million demand note issued by Modern Mind, with the difference representing a US$25 million loan that we extended to Modern Mind from the net proceeds of our July 2004 offering of
common shares. In addition, we extended a loan in the aggregate amount of US$50 million to Modern Mind from the net proceeds of our November 2004 convertible debt offering in exchange for demand notes issued by Modern Mind in the same aggregate
amount. As of March 31, 2010, the aggregate amount of total loans we extended to Modern Mind was US$130.3 million. The demand notes are convertible at any time into common shares representing, immediately after the conversion, almost 100% of
the then outstanding common shares of Modern Mind at a conversion rate of US$1.00 for each common share of Modern Mind. Payment under the demand notes are fully and unconditionally guaranteed by Jesper Limited and secured by a pledge agreement in
respect of the entire equity interest in Modern Mind and ChipMOS Shanghai. We have obtained from Jesper Limited an irrevocable option to acquire at any time the common shares of Modern Mind then owned by Jesper Limited.

In addition, on April 22, 2004, ChipMOS Hong Kong and ChipMOS Shanghai entered into an exclusive services agreement, pursuant to
which ChipMOS Shanghai will provide its services exclusively to ChipMOS Hong Kong or customers designated by ChipMOS Hong Kong. Under the exclusive services agreement, ChipMOS Hong Kong will purchase and consign to ChipMOS Shanghai all of the
equipment required to render those services. The exclusive services agreement has a term of ten years, which is automatically renewable for an additional ten-year period unless either party provides written notice of intention to terminate at least
30 days prior to the expiration of such ten-year term. In addition, ChipMOS Hong Kong may terminate the exclusive services agreement at any time by giving 30 days prior written notice.

ThaiLin Semiconductor Corp.
ThaiLin was incorporated in Taiwan in May 1996, and is listed on the GreTai Securities Market in Taiwan. It is engaged in the provision of semiconductor testing services. ChipMOS Taiwan acquired a 41.8% interest in ThaiLin in December 2002. Under
applicable accounting principles, ThaiLin was consolidated into our consolidated financial statements in 2003 because ChipMOS Taiwan was deemed to exert significant control over ThaiLin through common directors and management.

In August 2004, ThaiLin completed a NT$1,000 million convertible bond offering, and ChipMOS Taiwan purchased bonds in an amount of NT$100
million in that offering to maintain its percentage ownership in ThaiLin. ChipMOS Taiwan converted these convertible bonds in March 2005.

On August 15, 2005, ThaiLin entered into a merger agreement with ChipMOS Logic, whereby ChipMOS Logic agreed to be merged into
ThaiLin, with ThaiLin as surviving entity. Under the merger agreement, shareholders of ChipMOS Logic received one common share of ThaiLin in exchange for 2.8 common shares of ChipMOS Logic. As a result, ThaiLin issued approximately 43 million
shares (which represented approximately 14.4% of ThaiLins outstanding shares immediately after the completion of the transaction) to ChipMOS Logic shareholders. The transaction closed on December 1, 2005.

On March 4, 2008, ChipMOS Taiwan made a loan in an amount of NT$145 million that bears interest at a rate of 4.69% per annum to
Taiwan Kolin Co. Ltd., or Kolin, a major shareholder of ThaiLin, ChipMOS Taiwans 42.9% owned subsidiary. NT$15 million of this loan was repaid in 2008. The loan is secured by a pledge by Kolin of 11 million common shares of ThaiLin.
See Item 7. Major Shareholders and Related Party TransactionsRelated Party TransactionsThaiLin Semiconductor Corp.

As of March 31, 2010, ChipMOS Taiwan held (excluding the ThaiLin common shares pledged to us in connection with the loan to Kolin) a
42.9% interest in ThaiLin. Mr. Shih-Jye Cheng, our chairman and chief executive officer and the director and chairman of ChipMOS Taiwan, is also a director and the chairman of ThaiLin. In addition, six of the nine directors of ThaiLin are
appointed by ChipMOS Taiwan.

As of March 31, 2010, ThaiLin held 6,493,998 of our outstanding shares, corresponding to
7.1% of all of our outstanding shares. See Item 7. Major Shareholders and Related Party Transactions  Related Party TransactionsThaiLin Semiconductor Corp.

CHANTEK ELECTRONIC CO., LTD. Chantek was incorporated in Taiwan in May 1989 and was listed on the GreTai Securities Market
in Taiwan until November 16, 2005. It provided semiconductor assembly services for low-density volatile and non-volatile memory semiconductors, consumer semiconductors and microcontroller semiconductors. ChipMOS Taiwan acquired its
ownership interest in Chantek in September 2002.

On November 21, 2005, Chantek was merged into ChipMOS Taiwan, with
ChipMOS Taiwan as the surviving entity. For additional information regarding the merger agreement, see  ChipMOS TECHNOLOGIES INC. above.

ChipMOS Logic TECHNOLOGIES INC. ChipMOS Logic was incorporated in Taiwan in January 2004, with ChipMOS Taiwan holding a
62.5% interest and ThaiLin holding a 37.5% interest. ChipMOS Logic is engaged in logic testing services. On April 30, 2004, WWT, a Taiwan-based company engaged in logic testing services, merged into ChipMOS Logic, with ChipMOS Logic as the
surviving entity, in a stock-for-stock merger pursuant to which shareholders of WWT received one common share of ChipMOS Logic in exchange for 10 common shares of WWT. Upon consummation of the merger between WWT and ChipMOS Logic, ChipMOS Taiwan and
ThaiLin owned approximately 52.9% and 24.6%, respectively, of ChipMOS Logic, with the original management team of WWT, two original shareholders of WWT, including one creditor bank, and the management team of ChipMOS Logic owning the remaining
interest.

On December 1, 2005, ChipMOS Logic was merged into ThaiLin, with ThaiLin as the surviving entity. For
additional information regarding the merger agreement, see  ThaiLin Semiconductor Corp. above.

First Semiconductor Technology, Inc.First Semiconductor Technology, Inc. was
incorporated in the United States of America in June 1998 and engages in IC logic testing services. ChipMOS Taiwan acquired a 67.8% ownership interest in First Semiconductor Technology, Inc. on November 1, 2004 in connection with the purchase
of certain assets and equipment from First International Computer Testing and Assembly, and transferred this interest to First Semiconductor Technology, Inc. on April 29, 2005 pursuant to a share repurchase agreement.

Industry Background

We
provide a broad range of back-end testing services, including engineering testing, wafer probing and final testing of memory and logic/mixed-signal semiconductors. We also offer a broad selection of leadframe-based and organic substrate-based
package assembly services for memory and logic/mixed-signal semiconductors. Our advanced leadframe-based packages include thin small outline packages, or TSOPs, and our advanced organic substrate-based packages include fine-pitch ball grid array, or
fine-pitch BGA,

packages. In addition, we provide gold bumping, testing and assembly services for LCD and other flat-panel display driver
semiconductors by employing TCP, COF and COG technologies.

Semiconductors tested and assembled by us are used in personal
computers, graphics applications, such as game consoles and personal digital assistants, or PDAs, communications equipment, such as cellular handsets, and consumer electronic products and display applications, such as flat-panel displays. In 2009,
42.5% of our net revenue was derived from testing services for memory and logic/mixed-signal semiconductors, 35.9% from assembly services for memory and logic/mixed-signal semiconductors, and 21.6% from LCD and other flat-panel display driver
semiconductor testing and assembly services.

Semiconductor Industry Trends

Growth in the semiconductor industry is largely driven by end-user demand for consumer electronics, communications equipment and
computers, for which semiconductors are critical components. Highly cyclical, the worldwide semiconductor industry has experienced peaks and troughs over the last decade, with a severe downturn at the end of 2000 that was followed by a modest
recovery in late 2002. Beginning in the fourth quarter of 2008, the semiconductor industry commenced another downturn that increased in unprecedented severity into the first quarter of 2009. The overall semiconductor industry commenced to recover
from the downturn in the second quarter of 2009 and the positive recovery trend continues in 2010.

Selected Key
Semiconductor Markets

After such time as a recovery occurs in end-user demand for new and improved electronic products and
applications that is sufficient to reverse reduced demand trends that began in 2007 and are still continuing, various sectors of the semiconductor industry are in turn expected to benefit from a resumption in growth. These sectors include the memory
semiconductor market, and the LCD and other flat-panel display driver semiconductor market.

Memory Semiconductor Market

The potential for memory market growth is linked to anticipated memory content increases in consumer electronics and PC
applications (after such time as a recovery occurs in end-user demand for these) due to increasing operating system requirements, increasing use of graphics in gaming and other applications, continued growth of broadband content and a transition to
64-bit PC architecture. The memory market is dominated by two segmentsDRAM and flash memory. Potential growth in the DRAM market is expected to be driven by continued growth in both the commodity and niche DRAM market, as well as growth
opportunities in mobile DRAM as memory requirements significantly increase for mobile applications. Flash memory market potential growth is expected to be driven by increasing memory requirements for cellular handsets, digital cameras, digital audio
/video, and other mobile applications.

LCD and Other Flat-Panel Display Driver Semiconductor Market

Flat-panel displays are used in applications such as PC monitors, notebook computers, television sets, cellular handsets and digital
cameras. The end-user demand for LCD and other flat-panel display driver semiconductor experienced a downturn in 2007 and 2008. The LCD driver market started to recover in the second quarter of 2009 and the positive recovery trend continues in 2010.

Logic/Mixed-Signal Semiconductor Market

The communications market is one of the main drivers of potential growth in the semiconductor industry. Logic/mixed-signal semiconductors,
which are chips with analog functionality covering more than half of the chip area, are largely used in the communications market. The increasing use of digital technology in communications equipment requires chips with both digital and analog
functionality for applications such as modems, network routers, switches, cable set-top boxes and cellular handsets. As the size and cost of cellular handsets and other communications-related devices have decreased, components have increased in
complexity. Logic/mixed-signal semiconductors, such as LCD controllers and DVD controllers, are also used in consumer electronic products.

|Circuit Design    |  | The design of a semiconductor is developed by laying out circuit patterns and interconnections.                                                                                                                                                                                                                                                                                                                                                                                                                                             
|                  | 
|Wafer Fabrication |  | Wafer fabrication begins with the generation of a photomask, a photographic negative onto which a circuit design pattern is etched or transferred by an electron beam or laser
beam writer. Each completed wafer contains many fabricated chips, each known as a die.                                                                                                                                                                                                                                                                       
|                  | 
|Wafer Probe       |  | Each individual die is then electrically tested, or probed, for defects. Dies that fail this test are discarded, or, in some cases, salvaged using laser repair.                                                                                                                                                                                                                                                                                                                                                                            
|                  | 
|Assembly          |  | The assembly of semiconductors serves to protect the die, facilitates its integration into electronic systems and enables the dissipation of heat. The process begins with the
dicing of the wafers into chips. Each die is affixed to a leadframe-based or organic substrate-based package. Then, electrical connections are formed, in many cases by connecting the terminals on the die to the inner leads of the package using fine
metal wires. Finally, each chip is encapsulated for protection, usually in a molded epoxy enclosure.
|                  | 
|Final Test        |  | Assembled semiconductors are tested to ensure that the device meets performance specifications. Testing takes place on specialized equipment using software customized for each
application. For memory semiconductors, this process also includes burn-in testing to screen out defective devices by applying very high temperatures and voltages on to the memory device.                                                                                                                                                               

Outsourcing Trends in Semiconductor Manufacturing

Historically, integrated device manufacturers, or IDMs, designed, manufactured, tested and assembled semiconductors primarily at their own
facilities. In recent years, there has been a trend in the industry to outsource stages in the manufacturing process to reduce the high fixed costs resulting from the increasingly complex manufacturing process. Virtually every significant stage of
the manufacturing process can be outsourced. The independent semiconductor manufacturing services market currently consists of wafer fabrication and probing services and semiconductor testing and assembly services. Most of the worlds major
IDMs now use some independent semiconductor manufacturing services to maintain a strategic mix of internal and external manufacturing capacity. We believe that many of these IDMs are significantly reducing their investments in new semiconductor
testing and assembly facilities.

The availability of technologically advanced independent semiconductor manufacturing
services has also enabled the growth of fabless semiconductor companies that focus exclusively on semiconductor design and marketing and outsource their fabrication, testing and assembly requirements to independent companies.

##### Table of Contents

We believe the outsourcing of semiconductor manufacturing services, and in particular of
testing and assembly services, will increase for many reasons, including the following:

Significant Capital Expenditure
Requirements. Driven by increasingly sophisticated technological requirements, wafer fabrication, testing and assembly processes have become highly complex, requiring substantial investment in specialized equipment and facilities and
sophisticated engineering and manufacturing expertise. In addition, product life cycles have been shortening, magnifying the need to continually upgrade or replace manufacturing, testing and assembly equipment to accommodate new products. As a
result, new investments in in-house fabrication, testing and assembly facilities are becoming less desirable for IDMs because of the high investment costs, as well as difficulties in achieving sufficient economies of scale and utilization rates to
be competitive with the independent service providers. Independent foundry, testing and assembly companies, on the other hand, are able to realize the benefits of specialization and achieve economies of scale by providing services to a large base of
customers across a wide range of products. This enables them to reduce costs and shorten production cycles through high capacity utilization and process expertise.

Increasing Focus on Core Competencies. As the costs of semiconductor manufacturing facilities increase, semiconductor companies
are expected to further outsource their wafer fabrication, testing and assembly requirements to focus their resources on core competencies, such as semiconductor design and marketing.

Time-to-Market Pressure. Increasingly short product life cycles have amplified time-to-market pressure for semiconductor
companies, leading them to rely increasingly on independent companies as a key source for effective wafer fabrication, testing and assembly services.

Semiconductor Testing and Assembly Services Industry

Growth in the semiconductor testing and assembly services industry is driven by increased outsourcing of the various stages of the
semiconductor manufacturing process by IDMs and fabless semiconductor companies.

The Semiconductor Industry and Conditions
of Outsourcing in Taiwan and Mainland China

Taiwan is one of the worlds leading locations for outsourced
semiconductor manufacturing. The semiconductor industry in Taiwan has developed such that the various stages of the semiconductor manufacturing process have been disaggregated, thus allowing for specialization. The disaggregation of the
semiconductor manufacturing process in Taiwan permits these semiconductor manufacturing service providers to focus on particular parts of the production process, develop economies of scale, maintain higher capacity utilization rates and remain
flexible in responding to customer needs by lowering time-to-market pressure faced by semiconductor companies. There are several leading service providers in Taiwan, each of which offers substantial capacity, high-quality manufacturing, leading
semiconductor wafer fabrication, test, assembly and process technologies, and a full range of services. These service providers have access to an educated labor pool and a large number of engineers suitable for sophisticated manufacturing
industries. As a result, many of the worlds leading semiconductor companies outsource some or all of their semiconductor manufacturing needs to Taiwans semiconductor manufacturing service providers and take advantage of the close
proximity among facilities. In addition, companies located in Taiwan are very active in the design and manufacture of electronic systems, which has created significant local demand for semiconductor devices.

Mainland China has emerged as a similarly attractive location for outsourced semiconductor manufacturing. Mainland China is an attractive
manufacturing location for electronic products because companies can take advantage of a well-educated yet low-cost labor force, cost savings due to tax benefits and a large domestic market. These factors have driven increased relocation of much of
the electronics industry manufacturing and supply chain to Mainland China. An increasing number of global electronic systems manufacturers and contract manufacturers are relocating or have relocated production facilities to Mainland China. We
believe that these electronic product manufacturers and contract manufacturers will source an increasing portion of their demand for semiconductors from semiconductor suppliers located in Mainland China in order to reduce production cycle times,
decrease costs, simplify supply chain logistics and meet local content requirements. In line with this trend, we have in recent years expanded our operations in Mainland China.

Our Strategy

Our goal
is to reinforce our position as a leading independent provider of semiconductor testing and assembly services, concentrating principally on memory, logic/mixed-signal and LCD and other flat-panel display driver semiconductors. The principal
components of our business strategy are set forth below.

Focus on Providing Our Services to Potential Growth Segments of the Semiconductor
Industry.

We intend to continue our focus on developing and providing advanced testing and assembly services for
potential growth segments of the semiconductor industry, such as memory, logic/mixed-signal and LCD and other flat-panel display driver semiconductors. In 2009, our revenue from testing and assembly of semiconductors for these segments accounted for
all of our net revenue. We believe that our investments in equipment and research and development in some of these areas allow us to offer a differentiated service from our competition. In order to benefit from the expected resumption of growth in
these segments, we intend to continue to invest in capacity to meet the testing and assembly requirements of these key semiconductor market segments.

Continue to Invest in the Research and Development of Advanced Testing and Assembly Technologies.

We believe that our ability to progressively provide more advanced testing and assembly services to customers is critical to our
business. In addition, advanced semiconductor testing and assembly services typically have the potential to generate higher margins due to the greater expertise required and the more sophisticated technologies used. We will continue to invest in the
research and development of advanced testing and assembly technologies. For example, we are expanding our capabilities in fine-pitch BGA and the testing and assembly of COFs. We have also introduced fine-pitch COF based on our proprietary technology
and COG testing and assembly services for LCD and other flat-panel display driver semiconductors.

In addition, we will
continue to pursue the development of new testing and assembly technologies jointly with domestic and foreign research institutions and universities. We expect to focus our research and development efforts in the following areas:



| |  |  | developing new software conversion programs to increase the capabilities of our testers;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | developing technologies for wafer-level burn-in and testing before assembly;
| | - |  | ----------------------------------------------------------------------------



| |  |  | developing advanced assembly technologies for high-speed memory devices;
| | - |  | ------------------------------------------------------------------------



| |  |  | developing fine-pitch bumping, chip probing and bonding technologies for LCD drivers;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | improving manufacturing yields for new assembly technologies;
| | - |  | -------------------------------------------------------------



| |  |  | developing environmentally friendly assembly services that focus on eliminating the lead and halogen elements from the materials employed in the
package and reducing the toxicity of gaseous chemical wastes; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | implementing of radio frequency identification (RFID) logistics management system for the wafer probing process.
| | - |  | ----------------------------------------------------------------------------------------------------------------

In 2009, we spent approximately 3.1% of our net revenue on research and development. We will continue to invest our resources to recruit
and retain experienced research and development personnel. As of March 31, 2010, our research and development team comprised 263 persons.

Build on Our Strong Presence in Taiwan and Expand Our Operations Outside Taiwan.

We intend to build on our strong presence in key centers of semiconductor and electronics manufacturing to grow our business. Currently,
most of our operations are in Taiwan, one of the worlds leading locations for outsourced semiconductor manufacturing. This presence provides us with several advantages. First, our proximity to other semiconductor companies is attractive to
customers who wish to outsource various stages of the semiconductor manufacturing process. Second, our proximity to many of our suppliers, customers and the end-users of our customers products enables us to be involved in the early stages of
the semiconductor design process, enhances our ability to quickly respond to our customers changing requirements and shortens our customers time-to-market. Third, we have access to an educated labor pool and a large number of
engineers who are able to work closely with our customers and other providers of semiconductor manufacturing services.

As
with our operations in Taiwan, we intend to similarly benefit from our operations in Mainland China. We intend to invest in and expand our operations in Mainland China, increasing our testing and assembly services for memory semiconductors.

Depending on customers demands, market conditions and other relevant considerations, we may from time to time look into other
opportunities to expand our operations outside Taiwan.

Expand Our Offering of Vertically Integrated Services.

We believe that one of our competitive strengths is our ability to provide vertically integrated services to our customers.
Vertically integrated services consist of the integrated testing, assembly and direct shipment of semiconductors to end-users designated by our customers. Providing vertically integrated services enables us to shorten lead times for our customers.
As time-to-market and cost increasingly become sources of competitive advantage for our customers, they increasingly value our ability to provide them with comprehensive back-end services.

Through ChipMOS Taiwan, ThaiLin and ChipMOS Shanghai, we are able to offer vertically
integrated services for a broad range of products, including memory, logic/mixed-signal and LCD and other flat-panel display driver semiconductors. We believe that these affiliations, which offer complementary technologies, products and services as
well as additional capacity, will continue to enhance our own development and expansion efforts into new and potential growth markets. We intend to establish new alliances with leading companies and, if suitable opportunities arise, engage in merger
and acquisition activities that will further expand the services we can provide.

Focus on Increasing Sales through
Long-Term Agreements with Key Customers as well as Business with Smaller Customers.

From time to time, we
strategically agree to commit a portion of our testing and assembly capacity to certain of our customers. We intend to continue focus on increasing sales to key customers through long-term capacity agreements. The customers with which we currently
have long-term agreements include a reputable mixed-signal customer based in the US. See  Customers below for a more detailed discussion of these long-term agreements.

Recent global market and economic conditions have been unprecedented and challenging with tight credit conditions and recession in most
major economies continuing into 2010. Beginning in 2008, we also resumed our focus on our business with smaller customers or customers who do not place orders on a regular basis. We believe that the dual focused strategy would assist us to be better
prepared for the current economic volatility and ensure maximum utilization rate of our capacity and help us to develop closer relationships with all types of our customers.

The following is a description of our pre-assembly testing services:

Engineering Testing. We provide engineering testing services, including software program development, electrical design validation,
reliability and failure analyses.



| |  |  | Software Program Development. Design and test engineers develop a customized software program and related hardware to test semiconductors on
advanced testing equipment. A customized software program is required to test the conformity of each particular semiconductor to its particular function and specification.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Electrical Design Validation. A prototype of the designed semiconductor is submitted to electrical tests using advanced test equipment,
customized software programs and related hardware. These tests assess whether the prototype semiconductor complies with a variety of different operating specifications, including functionality, frequency, voltage, current, timing and temperature
range.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Reliability Analysis. Reliability analysis is designed to assess the long-term reliability of the semiconductor and its suitability of use for
its intended applications. Reliability testing may include operating-life evaluation, during which the semiconductor is subjected to high temperature and voltage tests.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Failure Analysis.If the prototype semiconductor does not perform to specifications during either the electrical validation or reliability
analysis process, failure analysis is performed to determine the reasons for the failure. As part of this analysis, the prototype semiconductor may be subjected to a variety of tests, including electron beam probing and electrical testing.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Wafer Probing. Wafer probing is the step immediately before the assembly of semiconductors and
involves visual inspection and electrical testing of the processed wafer for defects to ensure that it meets our customers specifications. Wafer probing employs sophisticated design and manufacturing technologies to connect the terminals of
each chip for testing. Defective chips are marked on the surface or memorized in an electronic file, known as a mapping file, to facilitate subsequent processing.

Laser Repairing. In laser repairing of memory products, specific poly or metal fuses are blown after wafer probing to enable a
spare row or column of a memory cell to replace a defective memory cell.

After assembly, we perform the following testing
services:

Burn-In Testing. This process screens out unreliable products using high temperature, high voltage and
prolonged stress to ensure that finished products will survive a long period of end-user service. This process is used only for memory products.

Top Marking. By using either a laser marker or an ink marker, we mark products according to our customers specifications,
including the logo, product type, date code and lot number.

Final Testing. Assembled semiconductors are tested to
ensure that the devices meet performance specifications. Tests are conducted using specialized equipment with software customized for each application in different temperature conditions ranging from minus 45 degrees celsius to 85 degrees celsius.
One of the tests includes speed testing to classify the parts into different speed grades.

Final Inspection and
Packing. Final inspection involves visual or auto-inspection of the devices to check for any bent leads, inaccurate markings or other construction defects. Packing involves dry packing, packing-in-tube and tape and reel. Dry pack involves
heating semiconductors in a tray at 125 to 150 degrees celsius for about two hours to remove the moisture before the semiconductors are vacuum-sealed in an aluminum bag. Packing-in-tube involves packing the semiconductors in anti-static tubes for
shipment. Tape and reel pack involves transferring semiconductors from a tray or tube onto an anti-static embossed tape and rolling the tape onto a reel for shipment to customers.

We offer a broad range of package formats designed to provide our customers with a broad array of assembly services. The assembly
services we offer customers are leadframe-based packages, which include thin small outline packages, and organic substrate-based packages, including fine-pitch BGA.

The differentiating characteristics of these packages include:



| |  |  | the size of the package;
| | - |  | ------------------------



| |  |  | the number of electrical connections which the package can support;
| | - |  | -------------------------------------------------------------------



| |  |  | the electrical performance and requirements of the package; and
| | - |  | ---------------------------------------------------------------



| |  |  | the heat dissipation requirements of the package.
| | - |  | -------------------------------------------------

As new applications for semiconductor devices require smaller components, the size of packages has also decreased. In leading-edge
packages, the size of the package is reduced to just slightly larger than the size of the individual chip itself in a process known as chip scale packaging.

As semiconductor devices increase in complexity, the number of electrical connections required also increases. Leadframe-based products
have electrical connections from the semiconductor device to the electronic product through leads on the perimeter of the package. Organic substrate-based products have solder balls on the bottom of the package, which create the electrical
connections with the product and can support large numbers of electrical connections.

Leadframe-Based Packages. These
are generally considered the most widely used package category. Each package consists of a semiconductor chip encapsulated in a plastic molding compound with metal leads on the perimeter. This design has evolved from a design plugging the leads into
holes on the circuit board to a design soldering the leads to the surface of the circuit board.

presents the basic components of a standard leadframe-based package for memory semiconductors:

To address the market for miniaturization of portable electronic products, we are currently
developing and will continue to develop increasingly smaller versions of leadframe-based packages to keep pace with continually shrinking semiconductor device sizes. Our advanced leadframe-based packages generally are thinner and smaller, have more
leads and have advanced thermal and electrical characteristics when compared to traditional packages. As a result of our continual product development, we offer leadframe-based packages with a wide range of lead counts and sizes to satisfy our
customers requirements.

The following table presents our principal leadframe-based packages, including the number of
leads in each package, commonly known as lead-count, a description of each package and the end-user applications of each package.

Organic Substrate-based Packages. As the number of leads surrounding a traditional
leadframe-based package increases, the leads must be placed closer together to reduce the size of the package. The close proximity of one lead to another can create electrical shorting problems and requires the development of increasingly
sophisticated and expensive techniques to accommodate the high number of leads on the circuit boards.

The BGA format solves
this problem by effectively creating external terminals on the bottom of the package in the form of small bumps or balls. These balls are evenly distributed across the entire bottom surface of the package, allowing greater pitch between the
individual terminals. The ball grid array configuration enables high-pin count devices to be manufactured less expensively with less delicate handling at installation.

Our organic substrate-based packages employ a fine-pitch BGA design, which uses a plastic or tape laminate rather than a leadframe and
places the electrical connections, or leads, on the bottom of the package rather than around the perimeter. The fine-pitch BGA format was developed to address the need for the smaller footprints required by advanced memory devices. Benefits of
ball grid array assembly over leadframe-based assembly include:



| |  |  | smaller size;
| | - |  | -------------



| |  |  | smaller footprint on a printed circuit board;
| | - |  | ---------------------------------------------



| |  |  | better electrical signal integrity; and
| | - |  | ---------------------------------------



| |  |  | easier attachment to a printed circuit board.

LCD and Other Flat-Panel Display Driver Semiconductors

We also offer testing and assembly services for LCD and other flat-panel display driver semiconductors. We employ TCP, COF and COG
technologies for testing and assembling LCD and other flat-panel display driver semiconductors. In addition, we offer gold bumping services to our customers.

Gold bumping technology, which can be used in TCP, COF and COG technologies, is a necessary interconnection technology for LCD and other
flat-panel display driver semiconductors. Most gold bumping services are performed on six- or eight-inch wafers. Gold bumping technology provides the best solution for fine-pitch chips and is able to meet the high production requirement for LCD and
other flat-panel display driver semiconductors or other chips that require thin packaging profiles.

The gold bumping
fabrication process uses thin film metal deposition, photolithography and electrical plating technologies. A series of barrier and seed metal layers are deposited over the surface of the wafer. A layer of thick photoresist material is spin-coated
over these barrier and seed layers. A photomask is used to pattern the locations over each of the bond pads that will be bumped. UV exposure and developing processes open the photoresist material, which defines the bump shape. The gold bump is then
electroplated over the pad and the deposited barrier metal layers. Once the plating is complete, a series of etching steps are used to remove the photoresist material and the metal layers that are covering the rest of the wafer. The gold bump
protects the underlying materials from being etched. The gold bumped wafers will go through an annealing furnace to soften the gold bumps to fit the hardness requirement of TCP, COF and COG assembly processes.

Tape Carrier Package Technology

TCPs offer a high number of inputs and outputs, a thin package profile and a smaller footprint on the circuit board, without compromising
performance. Key package features include surface mount technology design, fine-pitch tape format and slide carrier handling. Because of their flexibility and high number of inputs and outputs, TCPs are primarily employed either for STN-LCD or
TFT-LCD driver semiconductors.

Testing of TCPs. We conduct full function testing of LCD and other flat-panel display
driver semiconductors with a specially designed probe handler to ensure reliable contact to the test pads on the TCP tape. We can test STN-LCD or TFT-LCD driver semiconductors with frequencies of up to 750 MHz and at voltages up to 40V. The test is
performed in a temperature-controlled environment with the device in tape form. The assembled and tested LCD and other flat-panel display driver semiconductors in tape form are packed between spacer tapes together with a desiccant in an aluminum bag
to avoid contact during shipment.

Assembly of TCPs. TCPs use a tape-automated bonding process to connect die and tape.
The printed circuit tape is shipped with a reel. The reel is then placed onto an inner lead bonder, where the LCD or other flat-panel display driver semiconductor is configured onto the printed circuit tape. The resulting TCP component consists of
the device interconnected to a three-layer tape, which includes a polyamide-down carrier film, an epoxy-based adhesive layer and a metal layer. The tape metallization area of the interconnections is tin plated over a metal layer. The silicon chip
and inner lead area is encapsulated with a high temperature thermoset polymer after inner lead bonding. The back face of the chip is left un-sealed for thermal connection to the printed circuit board.

The following diagram presents the basic components of a TCP:

Chip-on-Film Technology

In 2001, we commenced testing and assembly services using COF technology. We have developed this proprietary technology from our existing
TCP technology, and it has been widely accepted by our customers. The primary use of the COF module is to replace the liquid crystal module, or LCM, in certain applications. LCM is mainly employed in handheld electronics, such as PDAs and cellular
handsets.

COF technology provides several additional advantages. For example, COF is able to meet the
size, weight and higher resolution requirements in electronic products, such as flat-panel displays. This is because of its structural design, including an adhesive-free two-layer tape that is highly flexible, bending strength and its capacity to
receive finer patterning pitch.

The TCP and COF assembly process involves the following steps:



|                   |  |

Chip-on-Glass Technology

COG technology is an electronic assembly technology that is used increasingly in assembling LCD and other flat-panel display driver
semiconductors for communications equipment. Compared to the traditional bonding process for TCP or COF, the new COG technology requires lower bonding temperature. In addition, the COG technology reduces assembly cost as it does not use tapes for
interconnection between the LCD panel and the printed circuit board.

The COG assembly technology involves the following
steps:



|                       |  |

Other Services

Drop Shipment

We offer drop shipment of semiconductors directly to end-users designated by our customers. We provide drop shipment services, including
assembly in customer-approved and branded boxes, to a majority of our testing and assembly customers. Since drop shipment eliminates the additional step of inspection by the customer prior to shipment to end-users, quality of service is a key to
successful drop shipment service. We believe that our ability to successfully execute our full range of services, including drop shipment services, is an important factor in maintaining existing customers as well as attracting new customers.

Software Development, Conversion and Optimization Program

We work closely with our customers to provide sophisticated software engineering services, including test program development, conversion
and optimization, and related hardware design. Generally, testing requires customized testing software and related hardware to be developed for each particular product. Software is often initially provided by the customer and then converted by us at
our facilities for use on one or more of our testing machines and contains varying functionality depending on the specified testing procedures. Once a conversion test program has been developed, we perform correlation and trial tests on the
semiconductors.

Customer feedback on the test results enables us to adjust the conversion test programs prior to actual
testing. We also typically assist our customers in collecting and analyzing the test results and recommend engineering solutions to improve their design and production process.

The majority of our customers purchase our services through purchase orders and provide us
three-month non-binding rolling forecasts on a monthly basis. The price for our services is typically agreed upon at the time when a purchase order is placed.

In 2006 and 2007, we strategically entered into or extended certain long-term agreements with some of our key customers, including a
reputable logic/mixed-signal customer based in the US, under which we reserved capacity for the customers primarily and the customer committed to place orders in the amount of the reserved capacity (which is subject in certain cases to reduction by
the customer).

Pursuant to the long-term service agreement we have entered into with ProMOS in July 2007, ProMOS agreed to
provide us with six month rolling forecast on testing and assembly service orders to be placed to us, and ProMOS guarantees that such orders will represent no less than certain percentage of ProMOS total production volume of these products
(excluding OEM products). In January 2008, at the request of ProMOS, we agreed to permit ProMOS to defer payment of aggregate service fees of NT$450 million to February 15, 2009. The deferred service fees, bore an interest at a rate of
4.69% per annum, were recorded as long-term accounts receivables as of December 31, 2007, and were paid in full by ProMOS in March and April 2008. In March 2008, ProMOS failed to place orders in the amount of the reserved capacity and
failed to meet its payment obligations under the long-term service agreement. In November 2008, we entered into a revised subcontracting contract with ProMOS by requiring ProMOS to provide wafers with a value of 80% of the subcontracting fee as
collateral. In May 2009, a further revised subcontracting contract was entered into by and between us and ProMOS under which ProMOS provided us with wafer as pledge and Work-In-Process, or WIP and existing finished goods as lien material. Part of
ProMOS receivables will be recovered through sales of the pledged wafer and lien material back to ProMOS with a discount to market price, and the remaining outstanding accounts receivables will be secured by equipment mortgage under the same
contract arrangement. Effective March 2009, we started to request prepayment from ProMOS. As of December 31, 2009, ProMOS owed the Company NT$464 million (US$15 million). We reserved an allowance in the full amount of the foregoing doubtful
receivables as of December 31, 2009. See Note 20 to our consolidated financial statements contained in this Annual Report on Form 20-F.

Pursuant to the long-term service agreement we have entered into with Spansion in September
2005, Spansion agreed to provide us with six month rolling forecast on testing and assembly service orders to be placed to us. In January 2009, Spansion defaulted on its payment obligations under the long-term service agreement and we subsequently
terminated the long-term service agreement with Spansion on February 19, 2009. Our service fee receivable from Spansion in connection with its default amounted to NT$1,539 million. Currently all of the service fees payable to us by Spansion are
via cash on delivery. On March 1, 2009, Spansion filed for a voluntary petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code. Subsequent to such filing, on March 16, 2009, ChipMOS Taiwan was elected as the co-chairman of
the Unsecured Creditor Committee to represent unsecured creditors in Spansions efforts to reorganize its debts under Chapter 11 petition. In early January, 2010, ChipMOS Taiwan resigned as a member of the Unsecured Creditor Committee.

On January 25, 2010, ChipMOS Taiwan entered into a definitive Transfer of Claim Agreement to sell to Citigroup the
general unsecured claim reflected in the proof of claim against Spansion Inc., Spansion Technology LLC, Spansion LLC, Spansion International Inc. and Cerium Laboratories LLC (collectively, Spansion) filed by ChipMOS Taiwan in U.S.
Bankruptcy Court. The claim that is the subject of the Transfer of Claim Agreement includes accounts receivable for testing and assembly services provided to Spansion in the amount of approximately US$66 million to US$70 million (the
Undisputed Claim). ChipMOS Taiwan received the purchase price for the Undisputed Claim of approximately US$33 million in February 2010 from Citigroup. The Transfer of Claim Agreement also includes the sale of breach of contract and
liquidated damages rights against Spansion in the amount of approximately US$234 million (the Damages Claim). The purchase price for the Damages Claim is expected to be an amount that will be determined based on a purchase rate of 50.2%
multiplied by the portion of the Damages Claim that is allowed by a final adjudication of the U.S. Bankruptcy Court. The purchase price for the Damages Claim is payable to ChipMOS Taiwan to the extent that the Court allows this claim. In furtherance
of the Transfer of Claim Agreement, the Company also has entered into an agreement to subscribe for, purchase and transfer to Citigroup rights offering shares to be issued by Spansion according to the Second Amended Joint Plan of Reorganization
filed in U.S. Bankruptcy Court. This agreement provides that Citigroup will pay to the Company the amount of the rights offering shares purchase price. Citigroup deposited the amount required to acquire the rights offering shares and the Company is
awaiting distribution of these shares.

On April 22, 2010, the Company announced that Spansion LLC and ChipMOS Taiwan
entered into a two-year wafer sort services agreement, utilizing the V5400 test platform, making ChipMOS Taiwan the exclusive wafer sort subcontractor of Spansion, except for any sort equipment operated by Spansion LLC or currently located at
Spansion Japan Limited. The wafer sort services agreement became effective upon the effective date of Spansions confirmed plan of reorganization. The U.S. Bankruptcy Court confirmed Spansions Second Amended Plan of Reorganization on
April 16, 2010. The effective date of Spansions plan of reorganization is May 10, 2010. The wafer sort services agreement became effective on May 10, 2010.

Beginning in 2008, we also resumed a focus on our business with smaller customers and customers who do not place orders on a regular
basis.

Qualification and Correlation by Customers

Our customers generally require that our facilities undergo a stringent qualification process during which the customer
evaluates our operations, production processes and product reliability, including engineering, delivery control and testing capabilities. The qualification process typically takes up to eight weeks, or longer, depending on the requirements of the
customer. For test qualification, after we have been qualified by a customer and before the customer delivers semiconductors to us for testing in volume, a process known as correlation is undertaken. During the correlation process, the
customer provides us with test criteria, information regarding process flow and sample semiconductors to be tested and either provides us with the test program or requests that we develop a new or conversion program. In some cases, the customer also
provides us with a data log of results of any testing of the semiconductor that the customer may have conducted previously. The correlation process typically takes up to two weeks, but can take longer depending on the requirements of the customer.

Sales and Marketing

We maintain sales and marketing offices in Taiwan, Hong Kong, Japan, Mainland China and the United States. Our sales and marketing
strategy is to focus on memory semiconductors in Taiwan, Japan, Korea and the United States, logic/mixed-signal semiconductors in Taiwan, Japan and the United States, LCD and other flat-panel display driver semiconductors in Japan, Taiwan, Hong Kong
and Mainland China, and module manufacturing in Taiwan and Mainland China. As of March 31, 2010, our sales and marketing efforts were primarily carried out by teams of sales professionals, application engineers and technicians, totaling 35
staff members. Each of these teams focuses on specific customers and/or geographic regions. As part of our emphasis on customer service, these teams:



| |  |  | actively participate in the design process at the customers facilities;
| | - |  | ------------------------------------------------------------------------



| |  |  | resolve customer testing and assembly issues; and
| | - |  | -------------------------------------------------



| |  |  | promote timely and individualized resolutions to customers issues.
| | - |  | -------------------------------------------------------------------

We conduct marketing research through our in-house customer service personnel and through our relationships with our customers and
suppliers to keep abreast of market trends and developments. Furthermore, we do product and system bench marking analyses to understand the application and assembly technology evolution, such as analysis on mobile handsets and CD-/DVD-ROM players.
In addition, we regularly collect data from different segments of the semiconductor industry and, when possible, we work closely with our customers to design and develop testing and assembly services for their new products. These
co-development or sponsorship projects can be critical when customers seek large-scale, early market entry with a significant new product.

We have appointed a non-exclusive sales agent for promoting our services for memory semiconductors in the United States, Japan and Korea.
Our sales agent helps us promote and market our services, maintain relations with our existing and potential customers and communicate with our customers on quality, specific requirements and delivery issues. We generally pay our sales agent a
commission of 1.5% to 2.5% of our revenue from services for memory semiconductors in the United States, Japan and Korea. In 2007, 2008 and 2009, we paid approximately NT$25 million, NT$12 million and NT$9 million (US$282 thousand), respectively, in
commissions to our sales agent.

Research and Development

We believe that research and development is critical to our future success. In 2007, 2008 and 2009, we spent approximately NT$322 million,
or 1%, NT$436 million, or 3% and NT$375 million (US$12 million), or 3%, respectively, of our net revenue on research and development. We intend to sustain these efforts.

Our research and development efforts have focused primarily on improving the efficiency, production yields and technologies of our
testing and assembly services. From time to time, we jointly develop new technologies with universities and research institutions. For testing, our research and development efforts focus particularly on thin wafer probing, non-clean sockets,
non-clean probing, fine-pitch MEMS probes, and testing of MEMS wafers/ devices. Our projects include:



| |  |  | Developing thin wafer probing technology to study the yield effect after processing;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | Developing non-clean probing and sockets to increase productivity and yield;
| | - |  | ----------------------------------------------------------------------------



| |  |  | Developing fine-pitch MEMS probes for advanced testing of MENS and COF products; and
| | - |  | ------------------------------------------------------------------------------------



| |  |  | Developing high-speed probing.
| | - |  | ------------------------------

We are also continuing development of interface designed to provide for high frequency
testing by minimizing electrical noise.

In the assembly areas, our research and development efforts focus on:



| |  |  | Copper wire bonding and low-cost wire bonding alternatives;
| | - |  | -----------------------------------------------------------



| |  |  | Wafer-level chip scale packaging and low-cost flip-chip integrated solution;
| | - |  | ----------------------------------------------------------------------------



| |  |  | Low cost, finepitch bumping solutions;
| | - |  | ---------------------------------------



| |  |  | High performance, fine pitch and miniaturization of packages;
| | - |  | -------------------------------------------------------------



| |  |  | Multi-chip assembly and modules;
| | - |  | --------------------------------



| |  |  | Stacked-die chip scale package;
| | - |  | -------------------------------



| |  |  | 3D IC packaging related technologies: thin wafer handling /testing/dicing;
| | - |  | --------------------------------------------------------------------------



| |  |  | Compression molding; and
| | - |  | ------------------------



| |  |  | Developing environmentally friendly assembly services.
| | - |  | ------------------------------------------------------

Our projects include developing multi-chip packages, flip-chip technologies, environmentally friendly products, 12-inch wafer
technologies, fine-pitch wire bonding technologies, 25-micron wafer thinning technology, and advanced packages. These are aimed to meet advanced needs for DDR III, COF modules, fine-pitch LCD driver bumping, mixed-signal assembly and advanced probe
card technologies. We work closely with our customers to optimize software and with equipment vendors to increase the efficiency and reliability of testing and assembly equipment. Our research and development operations also include a mechanical
engineering group, which currently designs handler kits for semiconductor testing and wafer probing, as well as software to optimize capacity utilization.

As of March 31, 2010, we employed 263 employees in our research and development activities. In addition, other management and
operational personnel are also involved in research and development activities but are not separately identified as research and development professionals.

We maintain laboratory facilities to analyze the characteristics of semiconductor packages by computer simulation, and verify their
performance by measurement tools. Shadow Moiré and Micro Moiré characterization capabilities were established in the Advanced Packaging Lab. Electrical measurement instruments and simulation software Agilent ADS, EMPro, and Ansoft Q3D
were set up in Electrical Measurement and Simulation Lab. These added capabilities allow us to support various advanced development work. The implementation of computer simulation, as compared with physical testing methods, is expected to
substantially shorten the development cycle and provides predictable performance of our packages.

Quality Control

We believe that our reputation for high quality and reliable services has been an important factor in attracting and retaining leading
international semiconductor companies as customers for our testing and assembly services. We are committed to delivering semiconductors that meet or exceed our customers specifications on time and at a competitive cost. We maintain quality
control staff at each of our facilities.

As of March 31, 2010, we employed 409 personnel for our quality control
activities. Our quality control staff typically includes engineers, technicians and other employees who monitor testing and assembly processes in order to ensure high quality. We employ quality control procedures in the following critical areas:



| |  |  | sales quality assurance: following market trends to anticipate customers future needs;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | design quality assurance: when developing new testing and assembly processes;
| | - |  | -----------------------------------------------------------------------------



| |  |  | supplier quality assurance: consulting with our long-term suppliers;
| | - |  | --------------------------------------------------------------------



| |  |  | manufacturing quality assurance: through a comprehensive monitoring program during mass production; and
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | service quality assurance: quickly and effectively responding to customers claims after completion of sale.
| | - |  | ------------------------------------------------------------------------------------------------------------

All of our facilities have been QS 9000 certified by the International Automotive Sector Group. In addition, our facilities in Hsinchu
and Tainan have been ISO 9002 certified. With respect to our quality management system, on November 26, 2003, ChipMOS Taiwan obtained ISO/TS 16949:2002 quality system certification. In 2006, the Chupei site obtained ISO/TS16949 quality system
certification. ThaiLin and ChipMOS Shanghai also obtained ISO/TS 16949:2002 quality system certification on September 6, 2005 and January 28, 2006, respectively.

##### Table of Contents

QS 9000 quality standards provide for continual improvement with an emphasis on the
prevention of defects and reduction of variation and waste in the supply chain, and a QS 9000 certification is required by certain semiconductor manufacturers as a threshold indicator of a companys quality control standards. An ISO 9002
certification is required by many countries for sales of industrial products. ISO/TS 16949:2002 certification system seeks to integrate quality management standards into the operation of a company, and emphasizes the supervision and measurement of
process and performance.

In addition to the quality management system, we also earned the 1998 QC Group Award from The
Chinese Society of Quality, which is equivalent to the similar award from the American Society of Quality. In 2003, ChipMOS passed SONY Green Partner (Tier 2) certification through its ProMOS channel, and in 2009, ChipMOS obtained SONY Green Partner
(Tier 1) certification due to its direct business relationship with SONY. ChipMOS Shanghai also obtained SONY Green Partner (Tier 2) certification through its ISSI channel in 2008. Our laboratories have also been awarded Chinese National Laboratory
accreditation under the categories of reliability test, electricity and temperature calibration.

Our testing and assembly
operations are carried out in clean rooms where air purity, temperature and humidity are controlled. To ensure the stability and integrity of our operations, we maintain clean rooms at our facilities that meet U.S. federal 209E class 100, 1,000,
10,000 and 100,000 standards. A class 1,000 clean room means a room containing less than 1,000 particles of contaminants per cubic foot.

We have established manufacturing quality control systems that are designed to ensure high-quality services to our customers and maintain
reliability and high production yields at our facilities. We employ specialized equipment for manufacturing quality and reliability control, including:



| |  |  | Joint Electron Device Engineering Council (JEDEC) standardized temperature cycling, thermal shock and pressure cook reliability tests;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | high and low temperature storage life tests, temperature and humidity bias and highly accelerated temperature/humidity stress test (HAST); and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | high resolution scanning acoustic tomography, scanning electronic microscope and X-Ray microscopy for physical failure analysis, curve tracer and
semi-probe station for electrical failure analysis.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, to enhance our performance and our
research and development capabilities, we also installed a series of high-cost equipment, such as temperature humidity bias testers, low temperature storage-life testers and highly accelerated stress testers. We believe that many of our competitors
do not own this equipment.

As a result of our ongoing focus on quality, in 2009, we achieved monthly assembly yields of an
average of 99.98% for our memory and logic/mixed-signal assembly packages, 99.91% for our COF packages and 99.79% for our COG packages. The assembly yield, which is the industry standard for measuring production yield, is equal to the number of
integrated circuit packages that are shipped back to customers divided by the number of individual integrated circuits that are attached to leadframes or organic substrate.

Raw Materials

Semiconductor testing requires minimal raw materials. Substantially all of the raw materials used in our memory and logic/mixed-signal
semiconductor assembly processes are interconnect materials such as leadframes, organic substrates, gold wire and molding compound. Raw materials used in the LCD and other flat-panel display driver semiconductor testing and assembly process include
carrier tape, resin, spacer tape, plastic reel, aluminum bags, and inner and outer boxes. Cost of raw materials represented 15%, 17% and 21% of our net revenue in 2007, 2008 and 2009, respectively.

We do not maintain large inventories of leadframes, organic substrates, gold wire or molding compound, but generally maintain sufficient
stock of each principal raw material for approximately one months production based on blanket orders and rolling forecasts of near-term requirements received from customers. In addition, since the commencement of economic downturn in second
quarter of 2008, due to the volatility of the semiconductor market, several of our principal suppliers have also ceased to stock inventories to be reserved to meet its customers production requirements. Instead, our suppliers now require
longer lead time for delivery of our supply orders. Despite shortages in the supply of materials, the prices of raw materials have decreased compared to prior to the economic downturn. See Item 3. Key InformationRisk FactorsRisks
Relating to Our BusinessIf we are unable to obtain raw materials and other necessary inputs from our suppliers in a timely and cost-effective manner, our production schedules would be delayed and we may lose customers and growth opportunities
and become less profitable for a discussion of the risks associated with our raw materials purchasing methods. For example, with the exception of aluminum bags and inner and outer boxes, which we acquire from local sources, the raw materials
used in our TCP/COF process and for modules are obtained from a limited number of Japanese suppliers.

Competition

The independent testing and assembly markets are very competitive. Our competitors include large IDMs with in-house testing and assembly
capabilities and other independent semiconductor testing and assembly companies, especially those offering vertically integrated testing and assembly services, such as Advanced Semiconductor Engineering Inc., Amkor Technology, Inc., Chipbond
Technology Corporation, King Yuan Electronics Co., Ltd., Powertech Technology Inc., Siliconware Precision, STATS ChipPAC Ltd. and United Test and Assembly Center Ltd. We believe that the principal measures of competitiveness in the independent
semiconductor testing industry are:



| |  |  | engineering capability of software development;
| | - |  | -----------------------------------------------



| |  |  | quality of service;
| | - |  | -------------------



| |  |  | flexibility;
| | - |  | ------------



| |  |  | capacity;
| | - |  | ---------



| |  |  | production cycle time; and
| | - |  | --------------------------



| |  |  | price.
| | - |  | ------

In
assembly services, we compete primarily on the basis of:



| |  |  | production yield;
| | - |  | -----------------



| |  |  | production cycle time;
| | - |  | ----------------------



| |  |  | process technology, including our COF technology for LCD and other flat-panel display driver semiconductor assembly services;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | quality of service;
| | - |  | -------------------



| |  |  | capacity;
| | - |  | ---------



| |  |  | location; and
| | - |  | -------------



| |  |  | price.
| | - |  | ------

IDMs that use our services continually evaluate our performance against their own in-house testing and assembly capabilities. These IDMs
may have access to more advanced technologies and greater financial and other resources than we do. We believe, however, that we can offer greater efficiency and lower costs while maintaining an equivalent or higher level of quality for three
reasons:



| |  |  | first, we offer a broader and more complex range of services as compared to the IDMs, which tend to focus their resources on improving their front-end
operations;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | second, we generally have lower unit costs because of our higher utilization rates and thus enabling us to operate at a more cost-effective structure
compared to the IDMs; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | finally, we offer a wider range of services in terms of complexity and technology.
| | - |  | ----------------------------------------------------------------------------------

Intellectual Property

As of March 31, 2010, we held 456 patents in Taiwan, one patent in the United Kingdom, one patent in France, one patent in Germany,
68 patents in the United States and 123 patents in the Peoples Republic of China relating to various semiconductor testing and assembly technologies. These patents will expire at various dates through to December 2028. As of March 31,
2010, we also had a total of 83 pending patent applications in the United States, 193 in Taiwan, and 140 in the Peoples Republic of China. In addition, we have registered ChipMOS and its logo and InPack as trademarks in
Taiwan, and ChipMOS and its logo as trademarks in the United States, the Peoples Republic of China, Singapore, Hong Kong, Korea, Japan and the European Community.

We expect to continue to file patent applications where appropriate to protect our proprietary technologies. We may need to enforce our
patents or other intellectual property rights or to defend ourselves against claimed infringement of the rights of others through litigation, which could result in substantial costs and a diversion of our resources. See Item 3. Key
InformationRisk FactorsRisks Relating to Our BusinessDisputes over intellectual property rights could be costly, deprive us of technologies necessary for us to stay competitive, render us unable to provide some of our services and
reduce our opportunities to generate revenue and Item 8. Financial InformationLegal Proceedings.

On June 3, 2006, ChipMOS Taiwan entered into a license agreement with Sharp
Corporation, or Sharp, pursuant to which we acquired a perpetual license to use TCP testing and assembly technology for a lump sum royalty payment of 10 million Japanese yen (approximately US$87 thousand), which we paid in July 2006. This
license agreement superseded the previous license agreement with Sharp entered into in February 2000 pursuant to which Sharp licensed to us TCP-related technology and intellectual property rights for five years starting from February 10, 2000
for a royalty fee based on the service fees paid to us by our customers. Our royalty obligations under the February 2000 license agreement were fully paid.

On April 12, 2007, ChipMOS Bermuda entered into an assignment agreement with ChipMOS Taiwan, pursuant to which ChipMOS Taiwan
assigned and transferred fifty percent of the title to, ownership of and interest in all of the technologies and intellectual property it owned as of that date to ChipMOS Bermuda for a purchase price of US$6.4 million, which was paid in full in June
2007.

Government Regulations

As discussed above under  Intellectual Property, governmental regulation of our intellectual property may materially
affect our business. The failure to protect our property rights would deprive us of our ability to stay competitive in the semi-conductor industry. Our intellectual property rights are protected by the relevant patent and intellectual property
agencies of the European Community, United States, the Peoples Republic of China, Singapore, Hong Kong, Korea, Japan and Taiwan.

Environmental Matters

Semiconductor testing does not generate significant pollutants. The semiconductor assembly process generates stationary acid and alkali
pollution, principally at the plating stages. Liquid waste is produced when silicon wafers are ground thinner and diced into chips with the aid of diamond saws and cooled with running water and during the gold bumping process. In addition, excess
material on leads and moldings are removed from assembled semiconductors in the trimming and dejunking processes, respectively. We have installed various types of liquid and gaseous chemical waste-treatment equipment at our semiconductor assembly
and gold bumping facilities. Since 2001, we have adopted certain environmentally-friendly production management systems, and have implemented certain measures intended to bring our assembly process in compliance with the Restriction of Hazardous
Substances Directive 2002/95/EC issued by the European Union. We believe that we have adopted adequate and effective environmental protection measures that are consistent with semiconductor industry practices in Taiwan and Mainland China. In
addition, we believe we are in compliance in all material respects with current environmental laws and regulations applicable to our operations and facilities.

All of our facilities in Taiwan and Mainland China have been certified as meeting the ISO 14001 environmental standards of the
International Organization for Standardization, and all of our facilities in Taiwan have been further certified as meeting the OHSAS18001 standards, of the International Organization for Standardization. Our testing facility at the Hsinchu Science
Park won both the Plant Greenery and Beautification Award in 1999, 2000 and 2002 and the Safety & Health Excellent Personnel Award in 2001 from the Science Park Administration, the Green Office Award from
the Environment Protection Administration of the ROC in 2000 and the Outstanding Voluntary Protection Program Award by the Labor Affairs Commission of the ROC in 1999. Our assembly facility at the Southern Taiwan Science Park won the
Green Office Award from the Environment Protection Administration of the ROC in 2001. In 2003, we won several environmental awards, including the Environmental Protection Excellent Unit Award, the Plant Greenery and
Beautification Award, the Environment Maintain Award and the Safety & Health Excellent Personnel Award, each awarded by the Science Park Administration.

We will continue to implement programs, measures and related training to reduce industrial waste, save energy and control pollution. In
2001, ChipMOS Taiwan completed a lead-free process control program, which offers a lead-free method in a semiconductor package, a lead-free plating, a lead-free solder ball and a lead-free reliability method and specification. In 2005, ChipMOS
Shanghai completed a similar lead-free process control program. In 2003 and 2008, ChipMOS Taiwan and ChipMOS Shanghai obtained Green Partner certification from Sony Corporation of Japan, respectively. The Green Partner program requires external
suppliers to meet SONYs Green Partner requirements. Standardizing on green, environmentally friendly products, production facilities and management systems, which has become an industry trend, and to many companies, a key criteria
in selection of their service providers.

Insurance

We maintain insurance policies on our buildings, equipment and inventories. These insurance policies cover property damages due to all
risks, including but not limited to, fire, lightning and earthquakes. The maximum coverage of property insurance for ChipMOS Taiwan and ThaiLin is approximately NT$53,786 million and NT$7,610 million, respectively. ChipMOS Shanghai also maintains
property insurance policies for a maximum coverage of approximately RMB753 million.

Insurance coverage on facilities under construction is maintained by us and our contractors,
who are obligated to procure necessary insurance policies and bear the relevant expenses of which we are the beneficiary. We also maintain insurance on the wafers delivered to us while these wafers are in our possession and during transportation
from suppliers to us and from us to our customers.

Employees

See Item 6. Directors, Senior Management and EmployeesEmployees for certain information relating to our employees.

Taxation

See Item 5. Operating and Financial Review and ProspectsTaxation for certain information regarding the effect of PRC and
ROC tax regulations on our operations.

Facilities

We provide testing services through our four facilities in Taiwan and one facility in Shanghai, with one facility at each of the following
locations: Chupei, the Hsinchu Industrial Park, the Hsinchu Science Park, the Southern Taiwan Science Park and the Shanghai Qingpu Industrial Zone. We provide assembly services through our facility at the Southern Taiwan Science Park and our
facility at the Shanghai Qingpu Industrial Zone. We own the land for our Hsinchu Industrial Park testing facility and Chupei facility and possess the land use right to the land on which our Shanghai Qingpu Industrial Zone facility is located until
2052, and, we lease two parcels of land for our Hsinchu Science Park testing facility with lease expiration in year 2017 and 2026, respectively, and Southern Taiwan Science Park facility with lease expiration in year 2017.

In March 2002, Modern Mind entered into a cooperation agreement with the Shanghai Qingpu Industrial Zone Development Group Company under
which Modern Mind has agreed to construct a permanent wholly-owned facility in the Shanghai Qingpu Industrial Zone to provide testing and assembly services. Modern Mind commenced construction of the facility in Shanghai in June 2002 and moved into
the new facility in August 2005, with the grand opening of the new facility in November 2005. Modern Mind currently offers testing and assembly services of memory semiconductors. In connection with the Shanghai operations, Modern Mind has invested
US$130 million in ChipMOS Shanghai for the facility and related equipment.

On August 24, 2004, we, through ThaiLin and
ChipMOS Taiwan, entered into an agreement for the acquisition of certain testing and assembly assets of FICTA, including 52 testers, 133 wire bonders, machinery, equipment, raw materials, spare parts and related patents.

In December 2004, we sold our Kaohsiung testing facility to Radiant Opto-Electronics Corporation.

Equipment

Testing of Memory and Logic/Mixed-Signal Semiconductors

Testing equipment is the most capital-intensive component of the memory and logic/mixed-signal semiconductors testing business. Upon the
acquisition of new testing equipment, we install, configure, calibrate and perform burn-in diagnostic tests on the equipment. We also establish parameters for the testing equipment based on anticipated requirements of existing and potential
customers and considerations relating to market trends. As of March 31, 2010, we operated 769 testers for testing memory and logic/mixed-signal semiconductors. We generally seek to purchase testers with similar functionality that are able to
test a variety of different semiconductors. We purchase testers from major international manufacturers, including Advantest Corporation, Verigy Ltd. and Credence Systems Corporation.

In general, particular semiconductors can be tested using a limited number of specially designed testers. As part of the qualification
process, customers will specify the machines on which their semiconductors may be tested. We often develop test program conversion tools that enable us to test semiconductors on multiple equipment platforms. This portability among testers enables us
to allocate semiconductor testing across our available testing capacity and thereby improve capacity utilization rates. If a customer requires the testing of a semiconductor that is not yet fully developed, the customer consigns its testing software
programs to us to test specific functions. If a customer specifies testing equipment that is not widely applicable to other semiconductors we test, we require the customer to furnish the equipment on a consignment basis.

We will continue to acquire additional testing equipment in the future to the extent market conditions, cash generated from operations,
the availability of financing and other factors make it desirable to do so. Some of the equipment and related spare parts that we require have been in short supply in recent years. Moreover, the equipment is only available from a limited number of
vendors or is manufactured in relatively limited quantities and may have lead time from order to delivery in excess of six months.

Assembly of Memory and Logic/Mixed-Signal Semiconductors

The number of wire bonders at a given facility is commonly used as a measure of the assembly capacity of the facility. Typically, wire
bonders may be used, with minor modifications, for the assembly of different products. We purchase wire bonders principally from Shinkawa Co., Ltd. and Kulicke & Soffa Industries Inc. As of March 31, 2010, we operated 611 wire bonders.
In addition to wire bonders, we maintain a variety of other types of assembly equipment, such as wafer grinders, wafer mounters, wafer saws, die bonders, automated molding machines, laser markers, solder platers, pad printers, dejunkers, trimmers,
formers, substrate saws and lead scanners.

Gold Bumping, Testing and Assembly of LCD and Other Flat-Panel Display Driver Semiconductors

We acquired TCP-related equipment from Sharp to begin our TCP-related services. We subsequently purchased additional
TCP-related testers from Yokogawa Electric Corp. and Advantest Corporation and assembly equipment from Shibaura Mechatronics Corp., Athlete FA Corp. and Sharp Takaya Electronics Corp. As of March 31, 2010, we operated 4 steppers and 11 sputters
for gold bumping, 127 inner-lead bonders for assembly and 193 testers for LCD and other flat-panel display driver semiconductors. We are currently in the process of purchasing additional testing equipment. The testing equipment can be used for the
TCP, COF and COG processes, while the inner-lead bonders are only used in the TCP and COF processes. The same types of wafer grinding, auto wafer mount and die saw equipment is used for the TCP, COF and COG processes. In addition, auto inspection
machines and manual work are used in the COG process, which is more labor-intensive than the TCP and COF processes.

Overview

We provide a broad range of back-end testing services, including wafer probing and final testing of memory and logic/mixed-signal
semiconductors. We also offer a broad selection of leadframe-based and organic substrate-based package assembly services for memory and logic/mixed-signal semiconductors. Our advanced leadframe-based packages include thin small outline packages, or
TSOPs, and our advanced organic substrate-based packages include fine-pitch ball grid array, or fine-pitch BGA, packages. In addition, we provide gold bumping, testing and assembly services for LCD and other flat-panel display driver semiconductors
by employing TCP, COF and COG technologies. In 2009, our consolidated net revenue was NT$12,150 million (US$380 million) and our net loss was NT$4,419 million (US$138 million).

We are a holding company, incorporated in Bermuda on August 1, 2000. We provide most of our services through our subsidiary, ChipMOS
Taiwan, and its subsidiaries and investees. ChipMOS Taiwan was incorporated in Taiwan in July 1997 as a joint venture company of Mosel and Siliconware Precision and with the participation of other investors. Following the completion of the share
exchange transaction between our company and ChipMOS Taiwan on September 14, 2007, ChipMOS Taiwan became a wholly-owned subsidiary of our company. In February 2010, we agreed to sell approximately 15.8% of ChipMOS Taiwans outstanding
shares to Siliconware Precision. Upon completion of that share purchase transaction by March 2011, we will own approximately 84.2% of ChipMOS Taiwans outstanding shares. In Taiwan, we conduct testing operations in our facilities at the Hsinchu
Science Park and the Hsinchu Industrial Park, gold bumping and wafer testing in our facility at Chupei, and testing and assembly operations in our facility at the Southern Taiwan Science Park. We also conduct operations in Mainland China through
ChipMOS Shanghai, a wholly-owned subsidiary of Modern Mind, which is one of our controlled consolidated subsidiaries. ChipMOS Shanghai operates a testing and assembly facility at the Qingpu Industrial Zone in Shanghai. Through our subsidiaries, we
also have equity interests in other companies that are engaged in the semiconductor industry. See Item 4. Information on the CompanyOverview of the Company for more details.

The following key trends are important to understanding our business:

Capital Intensive Nature of Our Business. Our operations, in particular our testing operations, are characterized by relatively
high fixed costs. We expect to continue to incur substantial depreciation and other expenses as a result of our previous acquisitions of testing and assembly equipment and facilities. Our profitability depends in part not only on absolute pricing
levels for our services, but also on capacity utilization rates for our testing and assembly equipment. In particular, increases or decreases in our capacity utilization rates could significantly affect our gross margins since the unit cost of
testing and assembly services generally decreases as fixed costs are allocated over a larger number of units. Due to the global credit and financial market crisis, we have experienced decrease in our capacity utilization rates for our testing and
assembly equipment during 2009 and therefore decrease in our gross margins.

The current generation of advanced testers
typically cost between US$2 million and US$5 million each, while wire bonders used in assembly typically cost approximately US$65 thousand each and inner-lead bonders for TCP and COF assembly cost approximately US$300 thousand each and COG
chip sorters cost approximately US$140 thousand each. We begin depreciating our equipment when it is placed into commercial operation. There may be a time lag between the time when our equipment is placed into commercial operation and when it
achieves high levels of utilization. In periods of depressed semiconductor industry conditions, we may experience lower than expected demand from our customers and a sharp decline in the average selling prices of our testing and assembly services,
resulting in an increase in depreciation expenses relative to net revenue. In particular, the capacity utilization rates for our testing equipment may be severely adversely affected during a semiconductor industry downturn as a result of the
decrease in outsourcing demand from integrated device manufacturers, or IDMs, which typically maintain larger in-house testing capacity than in-house assembly capacity.

Highly Cyclical Nature of the Semiconductor Industry. Highly cyclical, the worldwide semiconductor industry has experienced peaks
and troughs over the last decade, with a severe downturn beginning in the fourth quarter of 2000 that was followed by a recovery in early 2003. The significant decrease in market demand for semiconductors that began in 2000 adversely affected our
results of operations for 2001 and 2002. Beginning in the fourth quarter of 2008, the semiconductor industry commenced another significant downturn which continued and increased in severity towards the first quarter of 2009. The significant decrease
in market demand for semiconductors during such period adversely affected our results of operations for 2009. During periods of decreased demand for assembled semiconductors, some of our customers may forego, delay or simplify final testing of
certain types of semiconductors, such as DRAM, which may further decrease demand and average selling prices for our services and intensify our difficulties.

Declining Average Selling Prices of Our Testing and Assembly Services. The semiconductor industry is characterized by a general
decrease in prices for products and services over the course of their product and technology life cycles. The rate of decline is particularly steep during periods of intense competition and adverse market conditions. The average selling prices of
our testing and assembly services experienced sharp declines during such periods as a result of intense price competition from other independent testing and assembly companies that attempt to maintain high capacity utilization levels in the face of
reduced demand.

To offset the effects of decreasing average selling prices, we will continue to seek to:



| |  |  | improve production efficiency and attain high capacity utilization rates;
| | - |  | -------------------------------------------------------------------------



| |  |  | concentrate on testing of potentially high-demand, high-growth semiconductors;
| | - |  | ------------------------------------------------------------------------------



| |  |  | develop new assembly technologies; and
| | - |  | --------------------------------------



| |  |  | implement new technologies and platforms to shift into potentially higher margin services.
| | - |  | ------------------------------------------------------------------------------------------

Market Conditions for the End-User Applications for Semiconductors. Market conditions in the semiconductor industry, to a large
degree, track those for their end-user applications. Any deterioration in the market conditions for the end-user applications of semiconductors that we test and assemble may reduce demand for our services and, in turn, materially adversely affect
our financial condition and results of operations. Our net revenue is largely attributable to fees from testing and assembling semiconductors for use in personal computers, consumer and portable electronic products, display applications and
communications equipment. The markets for these products are intensely competitive, and a significant decrease in demand puts pricing pressure on our testing and assembly services and negatively affects our earnings. The oversupply of DRAM products
in the second half of 2007 and the weak demand in the DRAM market in 2008 and in the first quarter of 2009 resulted in significant reductions in the price of DRAM products, which in turn drove down the average selling prices for our testing and
assembly services for DRAM products in the second half of 2007, 2008 and the first quarter of 2009.

Change in Product
Mix. Declines in average selling prices have been partially offset over the last three years by a change in our revenue mix. In particular, revenue from testing and assembly of LCD and other flat-panel display driver semiconductors and 12-inch
wafer processing have increased as a percentage of our total net revenue over the 2007 to 2009 period. We intend to continue focusing on testing and assembling more semiconductors that have the potential to provide higher margins and developing and
offering new technologies in testing and assembly services, in order to mitigate the effects of declining average selling prices on our ability to attain profitability.

Recent Acquisitions

On
February 13, 2007, we entered into a share purchase and subscription agreement with ChipMOS Taiwan and Siliconware Precision under which we and ChipMOS Taiwan agreed to purchase all of Siliconware Precisions equity interest in ChipMOS
Taiwan, and Siliconware Precision agreed to subscribe for 12,174,998 of our newly issued common shares through a private placement. The transaction closed on March 27, 2007, and as of March 31, 2007, we held 99.1% of the outstanding common
shares of ChipMOS Taiwan. On April 12, 2007, we entered into a share exchange agreement with ChipMOS Taiwan pursuant to which we agreed to exchange one common share for every 8.4 ChipMOS Taiwan shares outstanding. The transaction closed on
September 14, 2007, and we issued 604,124 common shares to the holders of the ChipMOS Taiwan common shares in exchange for their ChipMOS Taiwan shares, and we and ChipMOS Taiwan paid NT$53 million in cash to purchase fractional shares and
shares held by dissenting shareholders. Following the completion of the share exchange transaction on September 14, 2007, ChipMOS Taiwan became our wholly-owned subsidiary. In February 2010, we agreed to sell approximately 15.8% of ChipMOS
Taiwans outstanding shares to Siliconware Precision. Upon completion of that share purchase transaction by March 2011, we will own approximately 84.2% of ChipMOS Taiwans outstanding shares. See Item 4. Information on the
CompanyOur Structure and History for description of our earlier merger events.

Our net revenue consists primarily of service fees for
testing and assembling semiconductors, and to a lesser extent, fees from equipment rentals to semiconductor manufacturers for engineering testing, less allowances for product returns. We offer testing and assembly services for memory semiconductors,
logic/mixed-signal semiconductors and testing and assembly services for LCD and other flat-panel display driver semiconductors.

Most of our customers do not place purchase orders far in advance and our contracts with customers generally do not require minimum
purchases of our products or services. Our customers purchase orders have varied significantly from period to period because demand for their products is often volatile. We have strategically entered into long-term capacity agreements with
some of our customers. Under certain of those long-term agreements, we have agreed to reserve capacity for our customers and our customers have agreed to place orders in the amount of the reserved capacity (which is subject in certain cases to
reduction by the customers). As part of our strategy, we intend to enter into additional long-term capacity agreements in the future if this approach continues to represent a potential growth opportunity for our business. Depending on customer
demands, market conditions and other considerations, we may explore opportunities to expand our operations outside Taiwan and Mainland China in connection with possible future long-term capacity agreements.

Our financial condition and results of operations have also been, and are likely to continue to be, affected by price pressures on our
service fees, which tend to decline in tandem with the declining average selling prices of the products we test and assemble over the course of their product and technology life cycles. In order to maintain our margins, it is necessary to offset the
fee erosion by continually improving our production efficiency and maintaining high capacity utilization rates. We also plan to continue to develop and implement new technologies and expand our services into potentially higher-margin segments. These
efforts require significant up front investment in advance of incremental revenue, which could impact our margins.

Pricing

We price our testing fees primarily based on the cost of testing the products to our customers specifications, including the costs
of the required material and components, the depreciation expenses relating to the equipment involved and our overhead expenses, and with reference to prevailing market prices. Accordingly, the testing fee for a particular product would principally
depend on the time taken to perform the tests, the complexity of the product and the testing process, and the cost of the equipment used to perform the test. For example, testing fees for memory semiconductors are significantly higher than those for
other products because of the longer time required and the need for burn-in testing.

We price our assembly services on a per
unit basis, taking into account the complexity of the package, our costs, including the costs of the required material and components, the depreciation expenses relating to the equipment involved and our overhead expenses, prevailing market
conditions, the order size, the strength and history of our relationship with the customer and our capacity utilization.

We
price our testing and assembly services for LCD and other flat-panel display driver semiconductors on the basis of our costs, including the costs of the required material and components, the depreciation expenses relating to the equipment involved
and our overhead expenses, and the price for comparable services.

##### Table of Contents

We offer volume discounts to all customers who purchase large quantities of our services and
special discounts to customers who use our vertically integrated services. On a case by case basis, we also may offer special payment terms, including longer payment cycles, to key customers during downturns in the market so as to retain business
from such key customers.

Revenue Recognition

We generally recognize our revenue upon shipment of tested and assembled semiconductors to locations designated by our customers,
including our internal warehouse for customers using our warehousing services. Revenue from product sales is recognized when risks of ownership are transferred to customers, generally upon shipment of the products. We submit invoices at the time of
shipment or delivery and generally require customers to pay within 60 days after the last day of the month during which the invoice was sent, except that we require Spansion and ProMOS, our largest and second largest customers, to pay by cash upon
delivery.

In January 2008, at the request of ProMOS, we agreed to permit ProMOS to defer payment of aggregate service fees of
NT$450 million to February 15, 2009. The deferred service fees, bore interest at a rate of 4.69% per annum, were recorded as long-term accounts receivable as of December 31, 2007, and were paid in full by ProMOS in March and April
2008. We also experienced collection problems for our receivables in connection with NT$578 million and NT$464 million (US$15 million) of receivables from ProMOS in 2008 and 2009, respectively. Full amount of allowance of the foregoing doubtful
receivables was reserved as of December 31, 2008 and 2009. Currently all of the services fees payable to us by ProMOS are prepaid in advance. See Item 4. Information on the Company  Customers.

We also experienced collection problems for our services in connection with NT$1,539 million and NT$2,232 million (US$70 million) of
receivables from Spansion in 2008 and 2009, respectively. Full amount of allowance of the foregoing doubtful receivables was reserved as of December 31, 2008 and 2009. Currently all of the service fees payable to us by Spansion are via cash on
delivery. See Item 4. Information on the Company  Customers.

We have not experienced other significant
collection problems for our services.

Related Party Revenues

In 2007, 2008 and 2009, 29%, 18% and 6%, respectively, of our net revenue were derived from related parties. While we believe that our
transactions with related parties were entered into on an arms length basis, we extended them favorable payment terms, as discussed in the preceding paragraph. See Item 7. Major Shareholders and Related Party Transactions for more
information concerning our related party transactions.

Geography and Currency

The majority of our net revenue is generated from customers headquartered in Taiwan, which represented 72%, 60% and 60% of our net revenue
in 2007, 2008 and 2009, respectively. We also generate net revenue from customers in the United States, Korea, Japan and other countries. Our service fees and revenue are generally denominated in the currency of the jurisdiction in which our
facilities are located, for example NT dollars for our Taiwan operations and RMB for our Mainland China operations. As we generate most of our net revenue from Taiwanese customers using our Taiwanese operations, and since most of our labor and
overhead costs are denominated in NT dollars, we consider the NT dollar to be our functional currency.

See Note 24 to our
consolidated financial statements contained in this Annual Report on Form 20-F and Item 11. Quantitative and Qualitative Disclosure about Market Risk  Market Risks  Foreign Currency Exchange Rate Risks for certain information
on our exchange rate risks.

Cost of Revenue and Gross Profit (Loss)

Our cost of revenue consists primarily of the following: depreciation and amortization expenses, raw material costs, and labor and
overhead expenses, which primarily include expensable equipments, sub-contracting fees and rental expenses. Our operations, in particular our testing operations, are characterized by relatively high fixed costs. We expect to continue to incur
substantial depreciation and other expenses as a result of our previous and future acquisitions of testing and assembly equipment and facilities, including our investment in our Mainland China operations. Our profitability depends in part not only
on absolute pricing levels for our services, but also on our capacity utilization rates. As of March 31, 2010, we had 769 testers, 171 burn-in ovens, 611 wire bonders, 127 inner-lead bonders, 4 steppers and 11 sputters. We use inner-lead
bonders for the assembly of LCD and other flat-panel display driver semiconductors using TCP or COF technology, and wire bonders for TSOP, BGA, and some other package assembly technologies. Our average capacity utilization rate for testing of memory
and logic/mixed-signal semiconductors was 78% in 2007, 65% in 2008 and 45% in 2009. Our average capacity utilization rate for assembly of memory and logic/mixed-signal semiconductors was 86% in 2007, 63% in 2008 and 64% in 2009. In addition, our
average capacity utilization rate for LCD and other flat-panel display driver semiconductor testing and assembly was 71% in 2007, 52% in 2008 and 50% in 2009.

Most of our labor and overhead costs are denominated in NT dollars. However, we also incur
costs of revenues and operating expenses associated with testing and assembly services in several other currencies, including Japanese yen, US dollars and RMB. In addition, a substantial portion of our capital expenditures, primarily for the
purchase of testing and assembly equipment, has been, and is expected to continue to be, denominated in Japanese yen with much of the remainder denominated in US dollars.

Operating Expenses

Research and Development

Research and development expenses consist primarily of personnel expenses, amortization expenses relating to technology, expenditures to
qualify our services for specific customers and other consulting fees and certification fees paid to third parties. Research and development expenses are recognized as they are incurred. We currently expect that research and development expenses
will increase in the future as we continue to explore new technologies and service offerings. We also expect to hire additional employees in our research and development department.

Sales and Marketing

Sales and marketing expenses consist primarily of shipping and handling expenses incurred in delivering products to our customers
designated locations, advertising, corporate communications and other marketing expenses, salary expenses for sales and marketing personnel, sales commission, professional service fees, bad debt provision and service support expenses.

General and Administrative

General and administrative expenses consist of salaries and related expenses for executive, finance and accounting, and management
information systems personnel, professional service fees, and other corporate expenses. They also include stock-based compensation that is expensed using the intrinsic value-based method and fair value method. See Item 6. Directors, Senior
Management and EmployeesShare Option Plan and Share Appreciation Rights Plan for more information concerning our share option plan. We expect general and administrative expenses to increase in absolute terms as we add personnel and incur
additional expenses related to the growth of our business and operations, particularly our Mainland China operations.

Other Income
(Expenses), Net

Our other income principally consists of interest income, foreign exchange gains, warehouse space rental
revenue, gains on sale of investments, gains on disposal of property, plant and equipment, fair value gains on financial assets, gain on disposal of land use right and gains on embedded derivative. In 2008, our other income included certain interest
income paid by Kolin under a loan repayable to ChipMOS Taiwan that bears interest at a rate of 4.69% per annum. NT$15 million of this loan was repaid in 2008. The loan is secured by a pledge by Kolin of 11 million common shares of ThaiLin.
See Item 7. Major Shareholders and Related Party TransactionsRelated Party TransactionsThaiLin Semiconductor Corp. Our other expenses principally consist of interest expense, investment losses recognized by equity method,
fair value loss on financial assets, financing costs, impairment losses, losses on disposal of property, plant and equipment, loss on embedded derivative, loss on redemption of convertible notes and foreign exchange losses.

Noncontrolling Interests and Interest in Bonuses Paid by Subsidiaries

Noncontrolling interests represent the portion of our income that is attributable to the shareholding in our consolidated subsidiaries
that we do not own. In 2007, our noncontrolling interests were attributable to the noncontrolling interests owned by Siliconware Precision and other investors in ChipMOS Taiwan prior to the completion of the share exchange transaction between
ChipMOS Bermuda and ChipMOS Taiwan on September 14, 2007, and the public shareholders interest in ThaiLin. In February 2010, we agreed to sell approximately 15.8% of ChipMOS Taiwans outstanding shares to Siliconware Precision. Upon
completion of that share purchase transaction by March 2011, we will own approximately 84.2% of ChipMOS Taiwans outstanding shares.

Interest in bonuses paid by subsidiaries represents our portion of ChipMOS Taiwans and ThaiLins distributable earnings that
are appropriated as bonuses to employees and remuneration to directors and supervisors of ChipMOS Taiwan and ThaiLin, as required by ROC regulations and ChipMOS Taiwans and ThaiLins articles of incorporation. ChipMOS Taiwan and ThaiLin
paid bonuses to directors, supervisors and employees of NT$391 million and NT$82 million, respectively, in 2007, and NT$387 million and NT$58 million, respectively, in 2008. ChipMOS Taiwan and ThaiLin did not pay any bonuses to directors,
supervisors and employees in 2009. Please see  US GAAP Reconciliation for a discussion of the significant impact such bonuses had on our net income under US GAAP.

Net Income

Our net
income was NT$2,219 million in 2007 and net loss was NT$7,270 million in 2008 and NT$4,419 million (US$138 million) in 2009, respectively. We believe our future results will be dependent upon the overall economic conditions in the markets we serve,
the competitive environment in which we operate, and our ability to successfully implement our strategy, among other things. For additional information on factors that will affect our future performance, see Item 3. Key InformationRisk
Factors.

Year Ended December 31, 2009 Compared to Year Ended December 31, 2008

Net Revenue. Our net revenue decreased by NT$4,860 million, or 29%, to NT$12,150 million (US$380 million) in 2009 from NT$17,010
million in 2008.

Net revenue from testing services for memory and logic/mixed-signal semiconductors decreased by NT$3,616
million, or 41%, to NT$5,171 million (US$162 million) in 2009 from NT$8,787 million in 2008, mainly due to a decrease in net revenue from testing services for memory semiconductors. Net revenue from testing services for memory semiconductors
decreased by NT$3,581 million, or 44%, to NT$4,646 million (US$146 million) in 2009 from NT$8,227 million in 2008, principally due to decreased capacity utilization rates and lower average selling price for DRAM products. Revenue for testing
services for logic/mixed-signal semiconductors decreased by NT$35 million, or 6%, to NT$525 million (US$16 million) in 2009 from NT$560 million in 2008, principally due to decreased capacity utilization rates. For each period of time selected, we
derived the capacity utilization rate for our testing operations by dividing the total number of hours of actual use of our facilities testing equipment units by the maximum number of hours that these equipment units were capable of being
used. The testing capacity utilization rate generally increases in correlation to increases in the total volume of our customer orders, and generally decreases in correlation to decreases in the total volume of our customer orders.

##### Table of Contents

Net revenue from assembly services for memory and logic/mixed-signal semiconductors, which
includes revenue from assembly services for memory and logic/mixed-signal semiconductors and revenue from our memory module manufacturing business, decreased by NT$1,065 million, or 20%, to NT$4,353 million (US$136 million) in 2009 from NT$5,418
million in 2008. This decrease was primarily the result of a decrease in net revenue from assembly services for memory semiconductors. Net revenue from

assembly services for memory semiconductors decreased by NT$1,255 million, or 27%, to NT$3,336 million (US$104 million) in 2009 from NT$4,591 million in
2008, primarily as a result of a decreased capacity utilization rate and lower average price for DDR II SDRAM products. Net revenue from assembly services for logic/mixed-signal semiconductors increased by NT$190 million, or 23%, to NT$1,017 million
(US$32 million) in 2009 from NT$827 million in 2008, principally as a result of higher customer demand. For each period of time selected, we derived the capacity utilization rate for our assembly operations by dividing the total number of units
actually produced by our assembly facilities by the maximum number of units that these facilities are capable of producing. The assembly capacity utilization rate generally increases in correlation to increases in the total volume of our customer
orders, and generally decreases in correlation to decreases in the total volume of our customer orders.

Net revenue from LCD
and other flat-panel display driver semiconductor testing and assembly services decreased by NT$179 million, or 6%, to NT$2,626 million (US$82 million) in 2009 from NT$2,805 million in 2008. This decrease was principally as a result of the weak
demand for LCD and other flat-panel display products in 2009, which in turn led to decreased capacity utilization rates as well as decreased average selling prices for services.

Cost of Revenue and Gross Margin. Cost of revenue decreased by NT$1,309 million, or 8%, to NT$15,661 million (US$490 million) in
2009 from NT$16,970 million in 2008, primarily due to the decrease of depreciation expenses of NT$531 million (US$17 million), salary and fringes expenses of NT$238 million (US$7 million) and direct material and direct labor expenses of NT$329
million (US$10 million) and NT$522 million (US$16 million), respectively. Direct material expenses decreased principally as a result of a decline in the capacity utilization rate. Our gross revenue is generally the product of the total volume of our
customer orders multiplied by the average selling price per assembly or testing deliverable unit, as the case may be. As a result, in a period where the average selling prices do not fluctuate significantly, increases or decreases in our capacity
utilization rates generally correlate to increases or decreases in our gross revenue. Periods with significant increases in the average selling prices reduce the negative impact on our gross revenue from any decreases in our capacity utilization
rates. Similarly, periods with significant decreases in the average selling prices reduce the positive impact on our gross revenue from any increases in our capacity utilization rates.

The Company has significant fixed costs in operating our assembly and testing facilities. For this reason, decreases in our cost of goods
sold during a period generally occur at a slower rate than decreases, during the same period, in our gross revenue due to lower capacity utilization rates, lower average selling prices, or both. Also, as a result, our gross margin and profitability
generally decreases in correlation to decreases in our capacity utilization rates, decreases in our average selling prices, or both. Similarly, our gross margin and profitability generally increases in correlation to increases in our capacity
utilization rates, increases in our average selling prices, or both. Due to the cyclical nature of the semiconductor industry, customer orders may change significantly, causing fluctuation in our capacity utilization rate and average selling price.

Our gross profit decreased to negative NT$3,511 million (US$110 million) in 2009 from NT$40 million in 2008. Our gross margin
was negative 29% in 2009, compared to 0.2% in 2008.

Our gross margin for testing services for memory and logic/mixed-signal
semiconductors decreased to negative 42% in 2009 from 10% in 2008, primarily due to a lower capacity utilization rate, which decreased to 45% in 2009 from 65% in 2008.

Our gross margin for assembly services for memory and logic/mixed-signal semiconductors decreased to negative 17% in 2009 from negative
6% in 2008, primarily due to pricing pressures that resulted from decreases in the pricing of end products.

Our gross margin
for LCD and other flat-panel display driver semiconductor testing and assembly services decreased to negative 21% in 2009 from negative 18% in 2008, primarily as a result of a decrease in the capacity utilization rate from 52% in 2008 to 50% in 2009
as well as a decreased average selling price for our services.

development expenses decreased by NT$61 million, or 14%, to NT$375 million (US$12 million) in 2009 from NT$436 million in 2008. This decrease was primarily due to lower salary expenses associated with a decrease in research and development
personnel, and the decrease of professional services fees and expensable equipment expenses.

General and Administrative
Expenses. General and administrative expenses decreased by NT$228 million, or 26%, to NT$658 million (US$21 million) in 2009 from NT$886 million in 2008, primarily due to the decrease of depreciation expenses.

Sales and Marketing Expenses. Sales and marketing expenses decreased by NT$1,802
million, or 76%, to NT$561 million (US$18 million) in 2009 from NT$2,363 million in 2008, primarily due to a decrease of NT$1,790 million (US$56 million) in allowance for doubtful receivables. The decrease was primarily due to full allowance already
made on outstanding receivables from Spansion and ProMOS in 2008.

Other Income (Expenses), Net. Other expenses, net
decreased by NT$3,404 million, or 104%, to other income of NT$117 million (US$4 million) in 2009 from other expenses of NT$3,287 million in 2008. This decrease was primarily due to the impairment loss on property, plant and equipment of NT$26
million (US$814 thousand) recognized in 2009, compared to an impairment loss on goodwill of NT$917 million and impairment loss on property, plant and equipment of NT$1,599 million recognized in 2008.

Income (Loss) Before Income Tax, Noncontrolling Interests and Interest in Bonuses to Directors, Supervisors and Employees Paid by
Subsidiaries. As a result of the foregoing, loss before income tax, noncontrolling interests and interests in bonuses to directors, supervisors and employees paid by subsidiaries decreased by 28% to a loss of NT$4,989 million (US$156 million) in
2009 from NT$6,930 million in 2008.

Income Tax Benefit (Expense). We had an income tax benefit of NT$421
million (US$13 million) in 2009 compared to income tax expenses of NT$121 million for 2008, primarily due to an increase of loss carried forward in 2009.

Net (Income) Loss Attributable to Noncontrolling Interests. The net loss of ThaiLin attributable to noncontrolling interests
amounted to NT$149 million (US$5 million) in 2009, compared a net loss of NT$143 million in 2008.

Interest in Bonuses paid
by Subsidiaries. Interest in bonuses paid by subsidiaries decreased by 100% to nil in 2009 from NT$362 million in 2008.

Net Income (Loss) Attributable to ChipMOS. As a result of the foregoing, the net loss attributable to ChipMOS was NT$4,419 million
(US$138 million) in 2009, compared to a net loss of NT$7,270 million in 2008.

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

Net Revenue. Our net revenue decreased by NT$6,588 million, or 28%, to NT$17,010
million in 2008 from NT$23,598 million in 2007.

Net revenue from testing services for memory and logic/mixed-signal
semiconductors decreased by NT$2,715 million, or 24%, to NT$8,787 million in 2008 from NT$11,502 million in 2007, mainly due to a decrease in net revenue from testing services for memory semiconductors. Net revenue from testing services for memory
semiconductors decreased by NT$2,629 million, or 24%, to NT$8,227 million in 2008 from NT$10,856 million in 2007, principally due to decreased capacity utilization rates and lower average selling price for DRAM products. Revenue for testing services
for logic/mixed-signal semiconductors decreased by NT$86 million, or 13%, to NT$560 million in 2008 from NT$646 million in 2007, principally due to decreased capacity utilization rates.

Net revenue from assembly services for memory and logic/mixed-signal semiconductors, which includes from assembly services for memory and
logic/mixed-signal semiconductors and revenue from our memory module manufacturing business, decreased by NT$2,682 million, or 33%, to NT$5,418 million in 2008 from NT$8,100 million in 2007. This decrease was primarily the result of a decrease in
net revenue from assembly services for memory semiconductors. Net revenue from assembly services for memory semiconductors decreased by NT$2,985 million, or 39%, to NT$4,591 million in 2008 from NT$7,576 million in 2007, primarily as a result of
decreased capacity utilization rate and lower average price for DDR II SDRAM products. Net revenue from assembly services for logic/mixed-signal semiconductors increased by NT$303 million, or 58%, to NT$827 million in 2008 from NT$524 million in
2007, principally as resulted from higher customer demand.

Net revenue from LCD and other flat-panel display driver
semiconductor testing and assembly services decreased by NT$1,191 million, or 30%, to NT$2,805 million in 2008 from NT$3,996 million in 2007. This decrease was principally as a result of the weak demand for LCD and other flat-panel display products
in 2008, which in turn led to decrease capacity utilization rates as well as decreased average selling prices for services.

Cost of Revenue and Gross Margin. Cost of revenue decreased by NT$474 million, or 3%, to NT$16,970 million in 2008 from NT$17,444
million in 2007, primarily due to the net effect of increase in leasing expense of NT$878 million and a decrease of expensable equipment of NT$224 million, direct material and direct labor by NT$603 million and NT$332 million, respectively. Leasing
expense increased due to the increase of leased machinery. Direct material decreased principally as a result of decline of capacity utilization rate.

##### Table of Contents

Our gross profit decreased to NT$40 million in 2008 from NT$6,154 million in 2007. Our gross
margin was 0.2% in 2008, compared to 26% in 2007.

Our gross margin for testing services for memory and logic/mixed-signal
semiconductors decreased to 10% in 2008 from 38% in 2007, primarily due to lower capacity utilization rate, which decreased to 65% in 2008 from 78% in 2007.

Our gross margin for assembly services for memory and logic/mixed-signal semiconductors decreased to negative 6% in 2008 from 18% in 2007
primarily due to a pricing pressure resulted from the decreasing pricing of end products.

Our gross margin for LCD and other
flat-panel display driver semiconductor testing and assembly services decreased significantly to negative 18% in 2008 from 8% in 2007, primarily as a result of a decrease in capacity utilization rate from 71% in 2007 to 52% in 2008 as well as
decreased average selling price for our services.

Research and Development Expenses. Research and development expenses
increased by NT$114 million, or 35%, to NT$436 million in 2008 from NT$322 million in 2007. This increase was primarily due to higher salary expenses associated with an increase in research and development personnel. We currently expect our research
and development expenses will increase in the future to our focus on research and development projects relating to advanced applications, such as thin wafer probing technology, non-clean probing and sockets, fine-pitch MEMS probes, high-speed
probing, copper wire bonding and low-cost wire bonding alternatives, wafer-level chip scale packaging and low-cost flip-chip integrated solution, low cost, fine-pitch bumping, MCP, stacked-die chip scale package, 3D IC packaging, compression
molding, etc.

General and Administrative Expenses. General and administrative expenses decreased by NT$184 million, or
17%, to NT$886 million in 2008 from NT$1,070 million in 2007, primarily due to decreased salary and fringes for the cost saving program.

Sales and Marketing Expenses. Sales and marketing expenses increased by NT$2,265 million, or 2,311%, to NT$2,363 million in 2008
from NT$98 million in 2007, primarily due to an increase of NT$2,282 million in bad debt. The increase in bad debt was primarily due to the full allowance made on outstanding receivables from Spansion and ProMOS.

Other Income (Expenses), Net. Other expenses, net increased by NT$2,618 million, or 391%, to NT$3,287 million in 2008 from NT$669
million in 2007. This increase was primarily due to the impairment loss on goodwill of NT$917 million and impairment loss on property, plant and equipment of NT$1,599 million recognized in 2008. The significant increase in impairment loss in 2008
was primarily due to a decreased estimated future cash inflow from the use of the related property, plant and equipment and resulted in the recoverable amount of the property, plant and equipment being lower than its carrying amount.

Income (Loss) Before Income Tax, Noncontrolling Interests and Interest in Bonuses to Directors, Supervisors and Employees Paid by
Subsidiaries. As a result of the foregoing, income before income tax, noncontrolling interests and interests in bonuses to directors, supervisors and employees paid by subsidiaries decreased by 274% to a loss of NT$6,930 million in 2008 from an
income of NT$3,993 million in 2007.

Income Tax Benefit (Expense). Income tax expenses decreased by NT$647 million, or
84%, to NT$121 million in 2008 from NT$768 million in 2007, primarily due to a significant increase in loss before income tax in 2008.

Net (Income) Loss Attributable to Noncontrolling Interests. In 2008, the net loss of ThaiLin attributable to noncontrolling
interests amounted to NT$143 million, compared to net income of ChipMOS Taiwan and ThaiLin attributable to noncontrolling interests of NT$720 million in 2007.

Interest in Bonuses paid by Subsidiaries. Interest in bonuses paid by subsidiaries increased by 27% to NT$362 million in 2008 from
NT$286 million in 2007 primarily as a result of ChipMOS Taiwan becoming a wholly-owned subsidiary in September 2007.

Net
Income (Loss) Attributable to ChipMOS. As a result of the foregoing, the net loss attributable to ChipMOS was NT$7,270 million in 2008, compared to a net income of NT$2,219 million in 2007.

Critical Accounting Policies

We prepare our consolidated financial statements in conformity with ROC GAAP. Under ROC GAAP, we are required to make certain estimates,
judgments and assumptions about matters that are highly uncertain at the time those estimates, judgments and assumptions are made, and our financial condition or results of operations may be materially impacted if we use different but nonetheless
reasonable estimates, judgments or assumptions about those matters for that particular period or if we change our estimates, judgments or assumptions from period to period.

##### Table of Contents

Under ROC GAAP, the significant accounting policies are set forth in Note 2 of the notes to
the consolidated financial statements contained in this Annual Report on Form 20-F. The significant accounting policies that require us to make estimates and assumptions about the effect of matters that are inherently uncertain are discussed below.
In connection with the reconciliation of our consolidated financial statements to US GAAP, there are no additional accounting policies that we believe are critical to us except as described below under  Convertible Notes and
 Share-Based Compensation.

Allowance for Doubtful Receivables and Sales Returns

Our accounts receivable balance on our balance sheet is affected by our allowances for doubtful accounts and sales returns, which reflect
our estimate of the expected amount of the receivables that we will not be able to collect and our estimate of the expected amount of sales returns.

Our determination of the allowance for doubtful receivables is based on our determination of two different types of reserves. The first
type of reserve involves an individual examination of available information regarding any customer that we have reason to believe may have an inability to meet its financial obligations. For these customers, we use our judgment, based on the
available facts and circumstances, and record a specific reserve for that customer against amounts due to reduce the receivable to the amount that is expected to be collected. These specific reserves are reevaluated and adjusted as additional
information is received. The second type of reserve is a general reserve established for all customers based on a range of percentages applied to aging categories. These percentages are based on historical collection and write-off experience. If
circumstances change, our estimates of the recoverability of amounts due to us could be reduced by a material amount. As of December 31, 2009, we provided NT$2,757 million (US$86 million) for the first type of reserve and NT$66 million (US$2
million) for the second type of reserve. See Item 4. Information on the CompanyCustomers.

Our determination
of the allowances for sales returns as of the end of any quarter is based upon calculating an average historical return rate, usually based on the previous three quarters, and multiplying this by the revenue of that quarter. As of December 31,
2009, we provided NT$114 million (US$4 million) for the allowance of sales returns.

The allowance we set aside for doubtful
receivables and sales returns was NT$260 million as of December 31, 2007, NT$2,433 million as of December 31, 2008, and NT$2,937 million (US$92 million) as of December 31, 2009. The allowances as of December 31, 2007, 2008 and
2009 represented 5%, 62% and 53%, respectively, of our accounts receivable and other receivables as of those dates. The allowance in 2007, 2008 and 2009 reflected a reduction of NT$5 million, NT$2,292 million and NT$1,065 million (US$33 million),
respectively, in accounts receivable and other receivables that were charged to sales and marketing expenses. If we were to change our estimate of the allowance for doubtful receivables and sales returns either upward or downward 10%, our operating
income would be affected by NT$409 thousand (US$13 thousand) for 2009.

An increase in our allowance for doubtful receivables
and sales returns would decrease our recorded revenue and our current assets.

Inventory Valuation

Inventories are stated at the lower of standard cost (adjusted to the approximate weighted average cost on the balance sheet date) or net
realizable value. Inventory write-down is made on an item-by-item basis, except where it may be appropriate to group similar or related items. Net realizable value is the estimated selling price of inventories less all estimated costs of completion
and necessary selling costs. Prior to January 1, 2009, inventories were stated at the lower of cost or market value. Any write-down was made on a total-inventory basis. Market value represented replacement cost for raw materials and net
realizable value for finished goods and work in progress.

In 2007, 2008 and 2009, we reserved NT$8 million, NT$99 million and
NT$199 million (US$6 million) of inventory valuation allowance, primarily due to the market price of tested and assembled DRAM and SDRAM inventory was below cost. In addition, we reserved NT$56 million in 2007, NT$3 million in 2008 and NT$1 million
(US$31 thousand) in 2009 for identified slow-moving inventories.

As of December 31, 2009, we recorded NT$200 million
(US$6 million) of inventory valuation allowances. If the prevailing market price of our testing and assembly services had been 10% lower, we would have been required to recognize a valuation allowance of approximately NT$80 million (US$2 million) in
2009 and would have decreased our inventory value by 9.2% and increased our net loss by 1.8%, respectively.

Valuation Allowance for Deferred Tax Assets

When we have net operating loss carry forwards, investment tax credits or temporary differences in the amount of tax recorded for tax
purposes and accounting purposes, we may be able to reduce the amount of tax that we would otherwise be required to pay in future periods. We recognize all existing future tax benefits arising from these tax attributes as deferred tax assets and
then, based on our internal estimates of our future profits, establish a valuation allowance equal to the extent, if any, that it is more likely than not that deferred tax assets will not be realized. We record an income tax expense or benefit in
our statement of operations when there is a net change in our total deferred tax assets and liabilities in a period. The ultimate realization of the deferred tax assets depends upon the generation of future taxable income during the periods in which
the net operating losses and temporary differences become deductible or the investment tax credits may be utilized. Specifically, our valuation allowances are impacted by our expected future revenue growth and profitability, tax holidays,
alternative minimum tax, and the amount of tax credits that can be utilized within the statutory period. In determining the amount of valuation allowance for deferred tax assets as of December 31, 2009, we considered past performance, the
general outlook of the semiconductor industry, future taxable income and prudent and feasible tax planning strategies.

Because the determination of the amount of valuation allowance is based, in part, on our forecast of future profitability, it is
inherently uncertain and subjective. Changes in market conditions and our assumptions may cause the actual future profitability to differ materially from our current expectation, which may require us to increase or decrease the amount of valuation
allowance that we have recorded. Because our expectation for future profitability is generally less during periods of reduced revenue, we will be more likely to provide significant valuation allowances with respect to deferred tax assets during
those periods of already reduced income.

As of December 31, 2007, 2008 and 2009, the ending balance for valuation
allowances were NT$834 million, and NT$1,823 million and NT$2,400 million (US$75 million), respectively.

Impairment
Loss of Long-Lived Assets

Under ROC GAAP, we record impairment losses on long-lived assets used in operations if
events and circumstances indicate that the assets might be impaired and the recoverable amounts of the assets of the cash-generating unit are less than the carrying amounts of those items. Assumptions about the recoverable amounts of the long-lived
assets require significant judgment on our expected cash flow. Our cash flow estimates are based on historical results adjusted to reflect our best estimate of future market and operating conditions. The net carrying value of assets not recoverable
is reduced to fair value. Our management periodically reviews the carrying value of our long-lived assets and this review is based upon our projections of anticipated future cash flows.

In determining whether any impairment charges were necessary for the property, plant and equipment and other assets as of
December 31, 2009, we assumed that the semiconductor industry will continue its growth in the next few years. Based upon our assumption of growth in the semiconductor industry and our other assumptions in our internal budget, for the purpose of
determining whether any impairment charges are necessary as of December 31, 2009, we estimated that our discounted future cash flows are smaller than our other property, plant and equipment. This indicated that these long-lived assets may be
impaired. If our current estimates of future cash flows decreases, those cash flows would be less than the reported amount of long-lived assets, and we would be required to recognize additional impairment loss, which would significantly increase our
net loss before taxes.

Under US GAAP, an impairment loss is recognized when the carrying amount of an asset or a group
of assets is not recoverable from the expected future cash flows and the impairment loss is measured as the difference between the fair value and the carrying amount of the asset or group of assets. The impairment loss is recorded in earnings and
cannot be reversed subsequently. Long-lived assets (excluding goodwill) held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Based on the assessment of our management, in 2009, we recognized NT$26 million (US$814 thousand) of impairment loss for
long-lived assets under ROC GAAP and US GAAP, respectively.

While we believe that our estimates of future cash flows are
reasonable, different assumptions regarding such cash flows could materially affect our evaluations.

Goodwill

Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the acquired net identified
tangible and intangible assets. Under US GAAP, and effective on January 1, 2005 under ROC GAAP, we assess the impairment of goodwill on an annual basis, or more frequently whenever triggering events or changes in circumstances indicate
that goodwill may be impaired and its carrying value may not be recoverable. Moreover, effective on January 1, 2006, goodwill is no longer amortizable under ROC GAAP. Factors we consider important which could trigger an impairment review
include, without limitation, the following:



| |  |  | a significant decline in our stock price for a sustained period; and
| | - |  | --------------------------------------------------------------------



| |  |  | a significant decline in our market capitalization relative to net book value.
| | - |  | ------------------------------------------------------------------------------

Application of the goodwill impairment test is highly subjective and requires significant judgment, including the identification of cash
generating units, assigning assets and liabilities to the relevant cash generating units, assigning goodwill to the relevant cash generating units, and determining the fair value of the relevant cash generating units. Under ROC GAAP, the fair value
of the cash generating units is compared to the associated carrying value including goodwill, while under US GAAP, the fair value of the reporting units is compared to the associated carrying value including goodwill.

Under ROC GAAP, goodwill recorded from the acquisition of ChipMOS Taiwan and ThaiLin is evaluated for impairment on an annual basis.
Based on our most recent evaluation, the fair value calculated by using the discounted future cash flows was lower than

the associated
carrying value. According to managements analysis incorporating the declining market capitalization in 2008, as well as the significant market deterioration and economic uncertainties impacting expected future demand management concluded that
the entire goodwill balance of NT$917 million was impaired, we recognized a non-cash impairment charge of approximately NT$917 million for the year ended December 31, 2008 to write-off the entire carrying value of goodwill.

Under US GAAP, the measurement of impairment of goodwill consists of two steps. In the first step, the fair value of the reporting
unit is compared to its carrying value, including goodwill. In connection with the preparation of the financial statements for the year ended December 31, 2008, management made a determination of the fair value of the two reporting units. Fair
value is determined using a combination of an income approach, which estimates fair value based upon future revenue, expenses and cash flows discounted to their present value, and a market approach, which estimates fair value using market multiples
to various financial measures compared to a set of comparable public companies listed on Taiwan Stock Exchange. Management concluded the estimated fair values of the reporting units were less than their net book value. Accordingly, the guidance in
US Statement of Financial Accounting Standards (SFAS) No. 142 requires a second step to determine the implied fair value of the Companys goodwill, and to compare it to the carrying value of the Companys goodwill is
adopted. Second step includes valuing all of the tangible and intangible assets and liabilities of the reporting unit as if it had been acquired in a business combination, including valuing all of its intangible assets even if they were not
currently recorded to determine the implied fair value of goodwill. Based on managements analysis incorporating the declining market capitalization in 2008, as well as the significant market deterioration and economic uncertainties impacting
expected future demand, management concluded that the entire goodwill balance of NT$969 million was impaired.

Convertible Notes

Under US GAAP, we are required to account for the conversion option in the 2006 Notes and the 2009 Notes as derivative liabilities in
accordance with SFAS No. 133 Accounting For Derivative Instruments And Hedging Activities and Emerging Interpretation Task Force (EITF) Issue No. 00-19 Accounting For Derivative Financial Instruments Indexed To And
Potentially Settled In A Companys Own Stock, which is now codified as FASB ASC 815. The discount attributable to the issuance date aggregate fair value of the conversion option, totaling NT$1,380 million (US$43 million), is amortized
using the effective interest method over the terms of the 2006 Notes and the 2009 Notes.

The change in fair value on
revaluation of the embedded derivative liabilities represents the difference between the fair value of the embedded derivative liabilities at the beginning of the reporting period and their fair value at the end of the reporting period. We are
required to record the change in fair value as a loss or gain on embedded derivative liabilities in determining net income under US GAAP. As of December 31, 2009, the fair value of the embedded derivative liabilities amounted to NT$130 million
(US$4 million) which resulted in a gain on embedded derivative liabilities of NT$51 million (US$2 million). These gains and losses were taken into account when determining our net income under US GAAP for the year ended December 31, 2009.

The fair values of embedded derivatives are determined using option pricing models, which require us to make various
assumptions, including among others, the expected volatility of our stock over the life of the option, market interest rates, credit spread and the expected life of the option. In determining these input assumptions, we consider historical trends
and other relevant factors which may change from period to period. Because the option pricing models are sensitive to change in the input assumptions, different determinations of the required inputs may result in different fair value estimates of
the options.

##### Table of Contents

Under ROC GAAP, we are required to bifurcate and separately account for embedded derivatives
contained in our convertible notes issued after 2005 in accordance with SFAS No. 34 Financial Instruments: Recognition and Measurement. For more information, see Notes 14, 26j and 27i to our consolidated financial statements
contained in this Annual Report on Form 20-F.

Share-Based Compensation

Under US GAAP, we are required to account for our employee share option plans under the fair-value-based method and to recognize
share-based compensation arrangements as expenses in the consolidated statements of operations, in accordance with SFAS No. 123(R) Share-Based Payments, which is now codified as FASB ASC 715. The determination of the fair value of
our share options on the date of grant under the Black Scholes Option Pricing Model is affected by the price of our common shares and assumptions of a number of variables, including the risk-free interest rate, the expected life of the options, the
estimated fair value of our common shares and the expected price volatility of our common shares over the term of the options. In 2009, the share-based compensation expense amounted to NT$55 million (US$2 million), which was taken into account when
determining our net income and shareholders equity under US GAAP for the year ended December 31, 2009.

Prior
to adopting FASB ASC 715 in 2006, share-based compensation arrangements were accounted for under Accounting Principles Board Opinion No. 25, which utilized an intrinsic value approach in recognizing compensation expense. Under ROC GAAP and
prior to January 1, 2008, we accounted for our share-based compensation arrangements under the intrinsic value method. Commencing January 1, 2008, we adopted ROC SFAS No. 39 Share-based Payment. After the adoption of SFAS
No. 39, our share-based compensation has been measured at the fair value of the options at grant date using an option valuation model. For more information, see Notes 2, 26k and 27h to our consolidated financial statements contained in this
Annual Report on Form 20-F.

Senior Managements Discussion with the Audit Committee

Our management has discussed the critical accounting policies described above with the audit committee of our board of directors and the
audit committee has reviewed our disclosure relating to the critical accounting policies in this section.

Impact of
Foreign Currency Fluctuations and Governmental or Political Factors

For a discussion of the impact of foreign currency
fluctuations and governmental economics, fiscal, monetary or political policies or factors that may directly or indirect impact us, see Item 3. Key InformationRisks FactorsRisks Relating to Our BusinessFluctuations in
exchange rate could result in foreign exchange losses and Item 3. Key InformationRisks FactorsRisks Relating to Countries in Which We Conduct Operations.

Liquidity and Capital Resources

Since our inception, we have funded our operations and growth primarily through the issuance of equity, a mixture of short- and long-term
loans and cash flow from operations. As of December 31, 2009, our primary sources of liquidity were cash and cash equivalents (excluding restricted cash and cash equivalents) of NT$3,885 million (US$122 million), short-term loans of NT$2,020
million (US$63 million) available to us in undrawn facilities, which have expired or will expire before 2010, and long-term loans of NT$528 million (US$17 million) available to us in undrawn facilities, which have expired or will expire before
December 2015. To meet our liquidity, capital spending and other capital needs, we have taken certain steps discussed below.

ChipMOS Taiwan requested and received from its bank creditors loan repayment extensions and modifications of certain terms on its loans
due from 2009 to 2013. Key extended repayment terms and conditions include: agreement by ChipMOS Taiwan to set aside NT$50 million per month with Bank of Taiwan for repayment of bank loans; agreement by all the banks that have loans due from ChipMOS
Taiwan in 2009 to 2013, to not unilaterally foreclose and seize any machinery, property or deposits of ChipMOS Taiwan; and agreement by these banks to waive any penalties that might have to be imposed on the Company in case of breach under the
original loan agreements. This loan repayment schedule is further discussed under Note 15 to our consolidated financial statements contained in this Annual Report on Form 20-F.

##### Table of Contents

Our bank creditors provided us with a waiver in February 2010 relating to any potential
covenant breaches under a syndicated loan facility agreement with Standard Chartered Bank (Hong Kong) Limited as agent. We have provided written notice to the indenture trustee for our outstanding convertible notes due 2011 and 2014, respectively,
about the nature of these negotiations with our bank creditors that led to our receipt of the waiver. Under the indenture for these notes, an event of default would occur if our repayment obligations under the facility accelerate, if the indenture
trustee or holders of at least 25% in aggregate principal amount of these notes deliver notice of this potential default and if this default is not cured within 30 days after notice. Although there can be no assurances that as a result of the loan
repayment schedule extension and waiver we will eventually attain profitable operations or will have sufficient liquidity to finance our ongoing obligations and operations, we believe that they significantly improve our cash position and reduce our
net current liabilities. See Item 3. Key InformationRisk FactorsRisks Relating to Economic Conditions and the Financial MarketsThe global credit and financial markets crisis could materially and adversely affect our business
and results of operations for additional information.

Net Cash Provided by Operating Activities

Net cash provided by operating activities totaled NT$781 million (US$24 million) in 2009, compared to NT$5,164 million in 2008. The
decrease in net cash provided by operating activities was primarily due to allowance for doubtful receivables, which decreased to NT$1,065 million (US$34 million) in 2009 from NT$2,292 million in 2008 and an increase in accounts receivables of
NT$1,241 million (US$39 million) in 2009, compared to a decrease of accounts receivable of NT$1,175 million in 2008. The decrease in net cash provided by operating activities was also attributable to a decrease in impairment loss on property, plant
and equipment to NT$26 million (US$814 thousand) in 2009 from NT$1,599 million in 2008. The decrease in impairment loss on property, plant and equipment was primarily the result of the recovery of the semiconductor industry compared with 2008.

Net cash provided by operating activities totaled NT$5,164 million in 2008, compared to NT$10,883 million in 2007. The
decrease in net cash provided by operating activities was primarily due to a net loss of NT$7,270 million in 2008, compared to net income of NT$2,219 million in 2007. Allowance for doubtful receivables increased to NT$2,292 million in 2008 from
NT$130 million in 2007. This increase was primarily due to the deteriorating financial condition of key customers as a result of the downturn in general economic conditions in 2008. The decrease in net cash provided by operating activities was also
partially offset by an increase in impairment loss on property, plant and equipment of NT$1,599 million in 2008, compared to nil in 2007. The increase in impairment loss on property, plant and equipment was primarily the result of the decline in
revenue from testing and assembly semiconductors which caused a decrease in cash inflows from the use of the related machinery and resulted in the recoverable amount of certain equipment being lower than the carrying value.

Net Cash Used in Investing Activities

Net cash used in investing activities totaled NT$1,043 million (US$33 million) in 2009, compared to NT$2,297 million in 2008. The decrease
in net cash used in investing activities was primarily the result of a decrease in capital expenditures budget for 2009 prepared in 2008 in view of the global economic downturn.Capital expenditures were NT$1,245 million (US$39 million) in
2009, compared to NT$2,391 million in 2008.

##### Table of Contents

Net cash used in investing activities totaled NT$2,297 million in 2008, compared to
NT$12,212 million in 2007. The decrease in net cash used in investing activities was primarily the result of a decrease in capital expenditures. Capital expenditures were NT$2,391 million in 2008, compared to NT$6,633 million in 2007. We incurred
significantly higher capital expenditures in 2007 primarily due to the capacity expansion for our agreement with Spansion. Cash payments incurred in connection with acquisitions of subsidiaries, which were nil in 2008, compared to NT$5,305 million
in 2007, related primarily to our acquisition of Siliconware Precisions shares of ChipMOS Taiwan in March 2007 and our exchange transaction with ChipMOS Taiwan on September 14, 2007.

Net Cash Used in and Provided by Financing Activities

Net cash used in financing activities totaled NT$2,504 million (US$78 million) in 2009, compared to NT$1,395 million in 2008. The increase
in net cash used in financing activities was primarily the result of the net payments of bank loans of NT$382 million (US$12 million) in 2009, compared to the net proceeds of NT$1,496 million in 2008 and net payments of long-term loans of NT$1,573
million (US$49 million) in 2009, compared to net proceeds of NT$1,386 million in 2008. This was partially offset by net payments of convertible notes of NT$517 million (US$16 million) in 2009, compared to net payments of NT$3,498 million in 2008.

Net cash used in financing activities totaled NT$1,395 million in 2008, compared to net cash provided by financing activities
NT$528 million in 2007. The increase in net cash used in financing activities was primarily the result of a decrease in convertible notes. Payments on convertible notes were NT$3,498 million in 2008, compared to NT$244 million in 2007, primarily due
to the buy back of convertible notes in 2008. The increase in net cash used in financing activities was also partially offset by an increase in proceeds from bank loan of NT$1,788 million in 2008, compared to NT$396 million in 2007.

Capital Resources

Capital expenditures in 2007 were funded by NT$10,883 million in cash flows from operating activities and NT$528 million in cash flows
from financing activities, mainly comprising new bank borrowings. Capital expenditures in 2008 were funded by NT$5,164 million in cash flows from operating activities. Capital expenditures in 2009 were funded by NT$781 million (US$24 million) in
cash flow from operating activities.

Steps taken with respect to generating additional working capital and to saving cash are
further discussed under Liquidity and Capital Resources.

##### Table of Contents

Our unused credit lines for short-term loans, as of December 31, 2009, totaled
NT$2,020 million (US$63 million), which have expired or will expire before 2010. As of December 31, 2009, we had available undrawn long-term credit facilities totaling NT$528 million (US$17 million).

As of December 31, 2009, we had credit loans for imports of machinery in the total amount of NT$15 million (US$469 thousand), which
are due between March 2010 and April 2010. We also had a short-term credit loan for importing raw materials and equipment in the total amount of NT$165 million (US$5 million), which is due between January 2010 and June 2010, and loans for import in
the total amount of NT$95 million (US$3 million), which is due by August 2010, and short-term working capital loan in the total amount of NT$2,088 million (US$65 million), which is due by December 2010.

We believe our current cash and cash equivalents, cash flow from operations and available credit facilities will be sufficient to meet
our capital spending and other capital needs through the end of June 2011. See Item 3. Key InformationRisk FactorsRisks Relating to Our BusinessOur significant amount of indebtedness and interest expense will limit our cash
flow and could adversely affect our operations. There can be no assurance regarding these matters, however, considering prevailing global economic conditions which continue to have a negative impact on our ability to accurately forecast our
revenues, results of operations and cash position.

Capital Lease Obligations

ChipMOS Taiwan negotiated with its lessors and converted the leases of certain equipment into capital leases in November 2009. As of
December 31, 2009, ChipMOS Taiwan had capital lease obligations of NT$2,275 million (US$71 million) to be repaid between 2010 and 2013, with an interest rate between 3.9567% to 3.9609%. The leased equipment and the corresponding capital leases
payable are recorded at the lower of the fair value of the leased equipment and the present value of the minimum lease payments of such assets. Under the capital leases, ChipMOS Taiwan is required to maintain certain financial ratios, beginning in
2010.

Convertible Notes

As of March 31, 2010, we had approximately US$42 million of convertible notes outstanding, including US$19 million in notes held by
ThaiLin, ChipMOS Taiwans 42.9% owned subsidiary.

On November 3, 2004, ChipMOS Bermuda issued US$85 million of
1.75 % Convertible Senior Notes due 2009 (the 2004 Notes), with a conversion price of US$7.85 per share (which was later adjusted to a conversion price of US$6.28 per share). In December 2004, we repurchased and cancelled
approximately US$1 million of the 2004 Notes. In October 2006, we made an induced conversion offer to the noteholders of the 2004 Notes in which noteholders converted approximately US$7 million in aggregate principal amount of the 2004 Notes into a
combination of common shares and cash. In November 2006, we repurchased approximately US$6 million in aggregate principal amount of the 2004 Notes pursuant to the noteholders put option under the indenture. In 2007, ThaiLin, ChipMOS
Taiwans 42.9% owned subsidiary, purchased approximately US$9 million of the 2004 Notes. During 2008, we repurchased approximately US$15 million of the 2004 Notes. In October 2009, we completed the closing of two privately negotiated
transactions with two investors holding, in aggregate, US$54 million of the 2004 Notes. In the first transaction, the Company and an institutional investor completed the exchange of US$45 million in outstanding 2004 Notes for US$15 million in cash
and US$16 million of the 10% Notes (as defined below) issued pursuant to an indenture with The Bank of New York Mellon as indenture trustee. In the second transaction, the Company and ThaiLin, ChipMOS Taiwans 42.9% owned subsidiary, completed
an exchange of US$9 million in outstanding 2004 Notes for US$3 million of the 10% Notes issued by us and US$6 million of the 8% Notes (as defined below). The remaining 2004 Notes, approximately US$2 million, were repaid in full at maturity.

In September 2006, we issued 3.375% Convertible Senior Notes due 2011 with a conversion price of US$6.85 per share, issued
pursuant to an indenture with The Bank of New York Mellon as the indenture trustee (the 2006 Notes). In 2007, we repurchased approximately US$1 million in aggregate principal amount of the 2006 Notes. In 2008, we repurchased
approximately US$97 million in aggregate principal amount of the 2006 Notes, primarily pursuant to the put option offered under the indenture. As of March 31, 2010, approximately US$2 million of the 2006 Notes were outstanding.

In October 2009, ThaiLin purchased additionally US$10 million of the 8% Notes at face value. In December 2009, we entered into purchase
agreements with seven investors (the Purchasers) for the purchase of the 8% Notes at face value and in the principal aggregate amount of US$10 million. The Purchasers included the Chairman and Chief Executive Officer of the Company,
Mr. Shih-Jye Cheng, who purchased the 8% Notes in the principal amount of US$1 million on the same terms and conditions as the other Purchasers. The closing occurred on December 29, 2009 for all Purchasers other than PacMOS and the
Chairman of PacMOS, Mr. Chi Hung Yip. The closing for PacMOS and Mr. Chi Hung Yip (in the aggregate amount of US$5 million) occurred in March 2010.

2010 Notes are all PIK notes, or payment in kind notes. Interest is payable on a quarterly basis and the Company has the option, subject to the satisfaction of certain conditions, of paying interest in cash or common shares or a
combination thereof. When interest is paid in our common shares, the number of common shares is equal to the amount of interest payable in common shares divided by the volume weighted average price of our common shares over a period of 10
consecutive trading days ending on the sixth trading day prior to the applicable payment date. In addition, upon conversion, an amount equal to the sum of any make-whole amount and any accrued and unpaid interest relating to the portion of the notes
being converted is payable to the converting holder. The make-whole amount is the amount of interest that would have accrued from the applicable conversion date, change of control repurchase date or redemption date, as the case may be, until the
stated maturity, discounted to the present value using the published yield on U.S. treasury notes having a comparable remaining tenor on the determination date plus 50 basis points; provided that the additional 50 basis points is not added if the
applicable treasury note rate is greater than two percent (2%).

The common shares convertible from the 10% Notes issued
pursuant to an indenture with The Bank of New York Mellon will be freely tradable within the United States without restriction or further registration under the Securities Act. See Item 7. Major Shareholders and Related Party
TransactionsMajor Shareholders for more information. With respect to the common shares convertible from the 10% Notes issued by us and the 8% Notes, we have entered into registration rights agreements with each purchaser of those bonds.

Pursuant to the terms of the 2006 Notes, 2009 Notes and 2010 Notes, if certain fundamental changes occur, the noteholders
have the right to require us to purchase the 2006 Notes, 2009 Notes and 2010 Notes at a repurchase price equal to 100% of the principal amount plus any accrued and unpaid interest on those notes to, but excluding, the repurchase date. Generally, a
fundamental change will be deemed to have occurred if:



| |  |  | any person other than us and our subsidiaries is or becomes the beneficial owner of more than 50% of our common shares;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | during any period of two consecutive years, individuals who at the beginning of such period constituted our board of directors cease for any reason to
constitute a majority of our board of directors then in office;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the termination of trading of our common shares; or
| | - |  | ---------------------------------------------------



| |  |  | certain mergers or consolidation involving us or the sale of all or substantially all of our assets.
| | - |  | ----------------------------------------------------------------------------------------------------

The holders right to require us to repurchase the 2006 Notes, 2009 Notes and 2010 Notes upon the occurrence of a fundamental change
is subject to a number of exceptions, including a trading price exception pursuant to which the repurchase right will not be exercisable if the trading price of our common shares exceeds a certain percentage of the conversion price.

The conversion prices of the 2006 Notes, 2009 Notes and 2010 Notes are subject to customary anti-dilution adjustments upon the occurrence
of certain events, including the declaration of stock dividends on our common shares and the repurchase of our common shares for consideration in excess of the market price.

See Item 3. Key InformationRisk FactorsRisks Relating to Economic Conditions and the Financial Markets for
additional information. For a discussion of the accounting for the conversion feature of the convertible notes under US GAAP, see  Critical Accounting PoliciesConvertible Notes and  US GAAP
Reconciliation.

Note 26 to our
consolidated financial statements contained in this Annual Report on Form 20-F describes the principal differences between ROC GAAP and US GAAP as they relate to us, and a reconciliation to US GAAP of certain items, including net income
and shareholders equity. Differences between ROC GAAP and US GAAP which have an effect on our net income as reported under ROC GAAP relate to, among other things, accrual for bonuses to employees, directors and supervisors, share-based
compensation and accounting for our convertible notes.

Under FASB ASC 718, share-based compensation transactions are
generally required to be accounted for using a fair-value-based method and recognized as expenses in the consolidated statements of operations. The standards became effective for the first interim period beginning after December 15, 2005. For
more information, see  Critical Accounting PoliciesShare-Based Compensation and Notes 26k and 27h to our consolidated financial statements contained in this Annual Report on Form 20-F.

Under FASB ASC 815, we are required to bifurcate and separately account for the conversion feature of our convertible notes as embedded
derivatives contained in the convertible notes. Under US GAAP, we are required to carry these embedded derivatives on our balance sheet at fair value and changes in fair values of these embedded derivatives are reflected in the consolidated
statement of operations. The change in fair value for embedded derivative liabilities for the conversion feature for the year ended December 31, 2009 under US GAAP was NT$51 million (US$2 million) and the resulting net loss for the year
ended December 31, 2009 under US GAAP was approximately NT$4,550 million (US$142 million). For more information, see Notes 26j and 27i to our consolidated financial statements contained in this Annual Report on Form 20-F.

Recent Accounting Pronouncements

See Note 27a to our consolidated financial statements contained in this Annual Report on Form 20-F for a description of the authoritative
accounting principals recognized by the Financial Accounting Standards Board (FASB), FASBs issuance of FASB Accounting Standard certification guidance and the extent to which these have an impact on the items reflected in our
consolidated financial statements.

Non-GAAP Financial Information Derived from US GAAP Measures

To supplement our consolidated income statement for the year ended December 31, 2009 on a ROC GAAP basis, our management uses a
non-GAAP measure of net loss, which is net loss pursuant to US GAAP adjusted to exclude two non-cash items referred to as special items. The two non-cash items excluded are changes in the fair value of the embedded derivative liabilities and
amortization of discount on convertible notes. These items are considered by the management to be outside of our core operating results. For example, changes in the fair value of the embedded derivative liabilities relate heavily to the price of our
companys common shares, interest rate and volatility, all of which are difficult to predict and outside of the control of our management.

For these reasons, our management uses non-GAAP adjusted measures of net income and non-GAAP net income per share, both derived from
US GAAP measures to evaluate the performance of our core businesses and to estimate future core performance. In addition, this information facilitates our managements internal comparisons to our historical operating results as well as to
the operating results of our competitors.

Our management finds these supplemental non-GAAP measures to be useful, and
believes these non-GAAP measures are useful to investors in enabling them to perform additional analyses of past, present and future operating performance and as a supplemental means to evaluate our core operating results. However, readers are
reminded that non-GAAP numbers are merely a supplement to, and not a replacement for, ROC GAAP or US GAAP financial measures. They should be read in conjunction with ROC GAAP and US GAAP financial measures. It should be noted as well that
our non-GAAP information may be different from the non-GAAP information provided by other companies.

The following table sets
forth, for the year ended December 31, 2009, reconciliation of US GAAP net loss to non-GAAP net loss:

Taxation

ChipMOS Taiwan was granted a ROC income tax exemption for a period of four years on income attributable to the expansion of its production
capacity as a result of purchases of new equipment funded by capital increases in 1998, 1999 and 2000. The tax exemption relating to the expansion of production capacity in 1998 and 1999 expired on December 31, 2002. The tax exemption relating
to the expansion of production capacity in 2000 expired on December 31, 2005. The tax exemption relating to the expansion of production capacity in 2001 expired on December 31, 2008, and has resulted in tax savings for ChipMOS Taiwan of
approximately NT$135 million in 2007.

ChipMOS Taiwan is also entitled to other tax incentives generally available to
Taiwan companies under the ROC Statute of Upgrading Industries, including tax credits of 30% for certain research and development and employee training expenses (and, if the amount of expenditure exceeds the average amount of expenditure for the
preceding two years, 50% of the excess amount may be credited against tax payable) and from 5% to 7% for certain investments in automated equipment and technology. These tax credits must be utilized within five years from the date on which they were
earned. In addition, except for the last year of the five-year period, the aggregate tax reduction from these tax credits for any year cannot exceed 50% of that years income tax liability. In 2007, 2008 and 2009, tax credits resulted in tax
savings for ChipMOS Taiwan of approximately NT$623 million, NT$161 million and nil, respectively.

ThaiLin was granted a ROC
income tax exemption for a period of five years on income attributable to the expansion of its production capacity as a result of purchases of new equipment funded by capital increase in 2002, which expired on December 31, 2009. This has
resulted in tax savings for ThaiLin of approximately NT$25 million in 2007, approximately NT$153 million in 2008 and nil in 2009.

ThaiLin is also entitled to other tax incentives generally available to Taiwan companies under the ROC Statute of Upgrading Industries,
including tax credits of 5% to 7% for certain investment in automated equipment and technology. These tax credits must be utilized within five years from the date on which they were earned. In addition, except for the last year of the five-year
period, the aggregate tax reduction from these tax credits for any year cannot exceed 50% of such years income tax liability. In 2007, 2008 and 2009, tax credits resulted in tax savings for ThaiLin of approximately NT$101 million, NT$5 million
and nil, respectively.

Net income generated by ChipMOS Taiwan and ThaiLin after January 1, 1998, which is not
distributed in the year following the year the income was generated, is subject to income tax at the rate of 10%. If that net income is subsequently distributed, the income tax previously paid on that income is credited against the amount of
withholding tax payable by shareholders, who are not individuals or entities of the Republic of China (for taxation purposes), in connection with the distribution.

The ROC government enacted the ROC Alternative Minimum Tax Act (AMT Act) that became effective on January 1, 2006. The
alternative minimum tax (AMT) imposed under the AMT Act is a supplemental tax which is payable if the income tax payable pursuant to the ROC Income Tax Act is below the minimum amount prescribed under the AMT Act. The taxable income for
calculating the AMT includes most income that is exempted from income tax under various legislations, such as tax holidays and investment tax credits. The AMT rate for business entities is 10%. However, the AMT Act grandfathered certain tax
exemptions and tax credits granted prior to the enactment of the AMT. The effects of the AMT on the tax expenses of ChipMOS Taiwan and ThaiLin in 2009 were not significant.

In accordance with the relevant tax rules and regulations of the PRC, ChipMOS Shanghai is entitled to an income tax exemption starting
from the first profit making year, with a full exemption available for the first two years and a 50% exemption available for three additional years thereafter. As the first profit-making year for ChipMOS Shanghai was 2004, the profits made in the
years 2004 and 2005 were fully exempt, and the profits made in the years 2006 through 2008 were subject to a 50% tax exemption. Commencing January 1, 2009, ChipMOS Shanghai is subject to a 25% tax on profits. Any tax losses can only be carried
forward for five years.

Special Investigation Committee

On December 21, 2004, in connection with alleged embezzlement at Pacific Electric by our former directors,
Mr. Hung-Chiu Hu and Mr. Jwo-Yi Miao, and money laundering by our former director, Mr. Robert Ma Kam Fook, our board established a special investigation committee to identify and investigate any past and present dealings between
ChipMOS Bermuda, including any of its subsidiaries and affiliates, and Messrs. Hu, Miao and Ma, and any companies or entities affiliated with them. For additional information on the allegations, see Item 3. Key InformationRisk
FactorsRisks Relating to Our BusinessThe ongoing criminal proceeding of and adverse publicity associated with Mr. Shih-Jye Cheng, our Chairman and Chief Executive Officer, and Mr. Hung-Chiu Hu, our former director, could have a
material adverse effect on our business and cause our stock price to decline.

The special investigation committee was
solely comprised of Messrs. Pierre Laflamme and Yeong-Her Wang, two of our companys independent directors. Concurrent with the establishment of the special investigation committee, our board requested the resignations of Mr. Hu and
Mr. Miao, who subsequently resigned from our board on June 2 and June 8, 2005, respectively. On December 21, 2004, our board also accepted the resignation of Mr. Ma. The special investigation committee engaged
Ernst & Young as its forensic accounting advisor and Baker & McKenzie as its legal advisor to review transactions that were similar in nature to the transactions that allegedly implicated Messrs. Hu, Miao and Ma at Pacific Electric
as well as significant related party transactions between ChipMOS Bermuda, including its subsidiaries and affiliates, and Messrs. Hu, Miao and Ma and any companies or entities affiliated with any of them. The special investigation committee also
engaged Hong Kong counsel.

##### Table of Contents

On June 23, 2005, the special investigation committee presented its final report to our
board of directors. The special investigation committee concluded that the review conducted by Ernst & Young and Baker & McKenzie did not reveal previously unknown information regarding losses suffered by ChipMOS Bermuda, other
than a potential liability relating to a credit facility entered into with Trident (Asia) Investments Limited, or Trident, and HSH Nordbank AG, Hong Kong Branch, or Nordbank. The special investigation committee noted that total losses from
transactions reviewed by it in the amount of NT$454 million (US$14 million), relating to impairment losses and realized losses of certain investments, were reflected in our 2002, 2003 and 2004 financial statements, and a potential decline in the
value of our investment in respect of Ultima Technology Corp. (BVI). In 2005, we recognized an impairment loss of NT$188 million (US$6 million) as a result of the decline in the value of our investment to Ultima Technology Corp. (BVI). See Note 8 to
our audited consolidated financial statements contained in this Annual Report on Form 20-F and Item 7. Major Shareholders and Related Party TransactionsRelated Party Transactions. The special investigation committee did not make
any factual findings as to the business purpose of the transactions reviewed or as to persons at our company responsible for such transactions. On August 26, 2005, our board dissolved the special investigation committee.

The Special Investigation Committee provided the following recommendations to our board of directors:



| |  |  | reinforce the internal controls related to our companys investment decisions, including the design and adoption of comprehensive internal control
procedures for investments in connection with our companys implementation of the internal control procedures required to comply with Section 404 of the Sarbanes Oxley Act of 2002 (Section 404);
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | strengthen the role of the board of directors in overseeing our companys investment activities;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | develop an internal control mechanism applicable to our companys selection of banks that our company will use for deposits so as to address both
commercial risks and reputational risks; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | develop more prudent and conservative procedures regarding the entry by our company into banking or other credit relationships.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------

As of December 31, 2006, we had taken the following measures to implement the recommendations of the
Special Investigation Committee:



| |  |  | engaged Ernst & Young to advise on the internal control over financial reporting requirements under Section 404, including testing and
monitoring the effectiveness of our internal controls over financial reporting;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | enhanced the board of directors ability to oversee our financial activities by adopting new internal control procedures, pursuant to which
decisions relating to derivatives, loans to others, endorsement and guarantee for third parties, and equity investments, exceeding certain limits, are subject to the board of directors approval; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | reduced the risks inherent in banking or other credit activities by adopting new internal control procedures, under which the application for any
credit line or the opening of any account at any overseas banks is required to be approved by the board of directors.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Special Committee

In
connection with the indictment of Mr. Shih-Jye Cheng by the Taipei District Prosecutors Office, our board of directors formed a special committee to evaluate the circumstances surrounding the indictment. As of March 31, 2010, the
special committee was comprised of two independent directors, Messrs. Yeong-Her Wang and Pierre Laflamme. The special committee has engaged K&L Gates LLP (formerly Kirkpatrick & Lockhart Preston Gates Ellis LLP) as its independent
international legal counsel and Baker & McKenzie as its independent ROC legal counsel, and Ernst & Young (formerly know as Diwan, Ernest & Young) as its accounting advisor to assist in its evaluation and provide
recommendations.

On June 28, 2006, the special committee issued its report, including its findings and recommendations.
Based upon the results of its investigation, it found that: (1) Mr. Cheng has declared himself not guilty of the charges described in the indictment; (2) Baker & McKenzie, after reviewing the indictment and the
prosecutors exhibits, have found that the evidence produced by the prosecutor seems to be inadequate and that there is a low probability of the charges in the indictment being founded; (3) the financial advisor to the special committee
have found that we suffered no loss (not taking into account exchange rate factors) and that all monies (capital and interest) were remitted back to our subsidiaries involved; (4) we have suffered no identifiable harm to our reputation or our
business; and (5) Mr. Cheng has not been impaired by the indictment to perform as our chairman and chief executive officer. The special committee recommended that our board maintains Mr. Cheng as our chairman and chief executive
officer with full responsibilities and our board unanimously (with Mr. Cheng having recused himself) resolved to accept and adopt the special committees recommendation with regard to Mr. Cheng.

##### Table of Contents

Our board of directors also resolved to continue the role of the special committee, for the
duration of the ongoing criminal proceeding involving Mr. Cheng to actively monitor any developments of the criminal investigation and take or recommend any appropriate action in light of such developments.

During its engagement by the special committee, Ernst & Young identified certain internal control weaknesses that existed during
the relevant period of the special committees investigation within ChipMOS Taiwan, ThaiLin and ChipMOS Logic (which was merged into ThaiLin on December 1, 2005). These weaknesses were in areas related to segregation of duties and of
corporate governance on investment authorizations, insufficiency of training for financial personnel in respect of derivative transactions, and non-compliance with the applicable ROC regulations. These identified internal control weaknesses have
either been addressed previously or are in the process of being remedied by our company and our subsidiaries.

In light of the
identification of these internal control weaknesses, the special committee recommended that the audit committee of the board of directors lead a special task force and report to the board of the directors as to the effectiveness of the
implementation of internal control over financial reporting, with an aim to enhance our companys financial personnels knowledge of derivative transactions. The board of directors unanimously resolved to accept and adopt the special
committees recommendation in this regard.

In August 2006, we engaged Ernst & Young to design certain employee
training sessions regarding derivative transactions and the applicable accounting treatment for these transactions.

See
Item 3. Key InformationRisk FactorsRisks Relating to Our BusinessThe ongoing criminal proceeding of and adverse publicity associated with Mr. Shih-Jye Cheng, our Chairman and Chief Executive Officer, and
Mr. Hung-Chiu Hu, our former director, could have a material adverse effect on our business and cause our stock price to decline.

Share Option Plan and Share Appreciation Rights Plan

We adopted a broad-based share option plan in 2001, which was amended at a special general meeting on March 19, 2004 to increase the
number of shares available for issuance under the share option plan from 5,800,000 to 9,000,000. In August 2006, we adopted a second broad-based share option plan, which has 7,000,000 shares available for issuance. Each share option plan provides
that our directors, officers, employees and those of our affiliates may, at the discretion of our board of directors or a committee, be granted options to purchase our shares at an exercise price of no less than the par value of our common shares.
The board or the committee has complete discretion to determine which eligible individuals are to receive option grants, the number of shares subject to each grant, the exercise price of all options granted, the vesting schedule to be in effect for
each option grant and the maximum term for which each granted option is to remain outstanding, up to a maximum term of ten years.

In 2007, we granted 1,884,400 share options, with an exercise price ranging from US$3.6380 to US$6.4770 per share. In 2007, 228,631 share
options were cancelled and 865,612 share options were exercised. In 2008, we granted 3,981,487 share options, with an exercise price ranging from US$0.1870 to US$2.9750 per share. In 2008, 763,229 share options were cancelled, 1,180,738 share
options were expired and 127,850 share options were exercised. In 2009, we granted 1,977,577 share options, with an exercise price ranging from US$0.2132 to US$0.6375 per share. In 2009, 697,181 share options were cancelled, 385,001 share options
were expired and nil share options were exercised. As of December 31, 2009, we had 10,153,958 share options outstanding, with an exercise price ranging from US$0.1870 to US$6.6300.

In September 2006 and August 2008, we adopted a share appreciation rights (SARs) plan pursuant to which we may issue up to
2,000,000 and 3,000,000 cash-settled SARs to our directors, officers, employees and those of our affiliates. Under the share appreciation rights plan, each holder of SARs, issued thereunder will be entitled to receive, on the applicable exercise
date, cash in an amount equal to the excess of the market value of our common shares on such date over the exercise price of such rights. Our board of directors or a relevant committee thereof has complete discretion over the administration of
the share appreciation rights plan, including determining the recipients of the share appreciation right awards, the number of rights awarded, the exercise date, the exercise price and other relevant terms. Unless earlier terminated by our board of
directors or the relevant board committee, the plan will remain effective until September 2016 and August 2018. In 2007, 582,000 SARs were granted, with an exercise price of ranging from US$3.6380 to US$6.4770. In 2007, 152,475 SARs were forfeited
and 1,500 SARs were exercised. In 2008, 623,285 SARs were granted, with an exercise price of ranging from US$0.1870 to US$2.9750. In 2008, 367,890 SARs were forfeited. In 2009, 1,173,060 SARs were granted, with an exercise price of ranging from
US$0.2210 to US$0.6375. In 2009, 204,662 SARs were forfeited. As of December 31, 2009, we had 2,853,928 SARs outstanding, with an exercise price ranging from US$0.1870 to US$6.4770.

ThaiLin Semiconductor Corp.

On March 4, 2008, ChipMOS Taiwan made a loan in an amount of NT$145 million that bears interest at a rate of 4.69% per annum to
Kolin, a major shareholder of ThaiLin. The loan is secured by a pledge by Kolin of 11 million common shares of ThaiLin. On August 22, 2008, Kolin repaid NT$15 million of the loan. On December 23, 2008, ChipMOS Taiwan notified Kolin to
proceed with the transfer of the collaterals ownership, the payment of unpaid loan and interest accrued in the amount of NT$130 million, and the payment of interest incurred due to loan repayment default under the loan. On January 20,
2009, Kolin informed ChipMOS that it could not fulfill request made by ChipMOS, including the transfer of shares since it is prohibited to do so under an interim restrictive order of disposition. Subsequently, Kolin was granted on March 27,
2009, pursuant to a ruling of Taiwan District Court on (Civil Ruling no.7 and No.9 of 2009), the approval for its reorganization and declaration of creditors rights application. Therefore, such shares shall still be deemed as the
creditors collateral. ChipMOS made the creditors rights application on April 21, 2009.

As of March 31,
2010, ThaiLin held 6,493,998 of our outstanding shares, corresponding to 7.1% of all of our outstanding shares. ThaiLins current holding includes 4,060,633 shares or 4.5% of our outstanding shares acquired pursuant to ThaiLins
enforcement of the collateral provided by ProMOS under the Stock Pledge Agreement dated December 3, 2008 entered into between ThaiLin and ProMOS, 2,025,455 shares or 2.2% of our outstanding shares accumulated from the Rule 10b5-1/10b-18
securities purchase program launched in December 2008, and 407,910 shares or 0.4% of our outstanding shares acquired pursuant to the interest shares payment of those holding the 2009 Notes.

ThaiLin has been our consolidated subsidiary since December 2003. On December 1, 2005, ChipMOS Logic merged into ThaiLin, with
ThaiLin as the surviving entity. See, Item 4. Information on the Company Our Structure and HistoryThaiLin Semiconductor Corp.

ProMOS Technologies Inc.

As of March 31, 2010, Mosel directly and indirectly owned 12.0% of ProMOS. Following the transfer of Mosels DRAM business to
ProMOS in 2003, sales to ProMOS accounted for 29% of our net revenue in 2007, 18% of our net revenue in 2008 and 6% of our net revenue in 2009.

On July 1, 2003, ChipMOS Taiwan entered into a long-term agreement with ProMOS, under which ChipMOS Taiwan reserves a specified
amount of capacity for DRAM testing and assembly services to ProMOS and under which ProMOS guarantees to place orders in the amount of the reserved capacity. This agreement was superseded in July 2007, when ChipMOS Taiwan and ProMOS entered into a
new long-term agreement with similar terms and conditions, except that under the new agreement, ProMOS will give ChipMOS six month rolling forecast on testing and assembly service orders to be placed to us, and ProMOS guarantees that such orders
will represent no less than certain percentage of ProMOS total production volume of these products (excluding OEM products). The price for the services of ChipMOS Taiwan under this agreement will be agreed upon quarterly, subject to certain
price adjustments. If ChipMOS Taiwan is unable to test and assemble the agreed number of DRAM, ProMOS may use a third party to cover the shortfall and ChipMOS Taiwan may be liable for, among other damages, any operation loss of ProMOS caused by such
delay or any additional costs in using a third party to cover the shortfall. If ProMOS fails to place orders in the amount of the reserved capacity, ChipMOS Taiwan is entitled to damages calculated based on the difference between the value of the
reserved capacity and the value of the actual used capacity, provided that the value of the capacity by ChipMOS Taiwan that has been used for other customers shall be deducted. In March 2008, ProMOS failed to place orders in the amount of the
reserved capacity. In November 2008, we entered into a revised subcontracting contract with ProMOS by requiring ProMOS to provide wafers with a value of 80% of the subcontracting fee as collateral. In May 2009, a further revised subcontracting
contract was entered into by and between us and ProMOS under which ProMOS provided us with wafer as pledge and Work-In-Process, or WIP and existing finished goods as lien material. Part of ProMOS receivables will be recovered through sales of
the pledged wafer and lien material back to ProMOS with a discount to market price, and the remaining outstanding accounts receivables will be secured by equipment mortgage under the same contract arrangement. Effective March 2009, we started to
request prepayment from ProMOS. See Note 20 to our audited consolidated financial statements contained in this Annual Report on Form 20-F.

Rental revenue from ProMOS in 2007 was NT$16 million. We received no rental revenue from ProMOS in 2008 and 2009.

Mou-Fu Investment Ltd.

As of March 31, 2010, Mosel held directly a 99.9% equity interest in Mou-Fu. In 2006, we paid Mou-Fu NT$3 million, for the provision
of shareholders services and NT$2 million for management expenses.

Legal Proceedings

In February 2006, ChipMOS Taiwan and ChipMOS USA received notice of a lawsuit filed by Tessera Technologies, Inc., or Tessera. The
complaint was initially filed in United States District Court for the Northern District of California (Civil Action No. C05-04063CW), or the California court. In an amended complaint, Tessera added ChipMOS Taiwan and ChipMOS USA, among several other
semiconductor companies, as co-defendants. The amended complaint alleges that ChipMOS Taiwan, ChipMOS USA and the other co-defendants infringed certain patents owned by Tessera and that ChipMOS Taiwan is in breach of a license agreement with
Tessera, or the Tessera license agreement. Tessera also sought unspecified damages and injunctive relief. ChipMOS Taiwan and ChipMOS USA have responded to the lawsuit by denying Tesseras claims of patent infringement and breach of contract.
ChipMOS USA and ChipMOS Taiwan have also raised various counterclaims for declaratory judgment and related affirmative defenses that the Tessera patents are invalid and unenforceable. In May 2007, the California court, with the concurrence of
ChipMOS Taiwan and ChipMOS USA, stayed all litigation in the California court as a result of a related investigation by the International Trade Commission, or ITC, initiated by Tessera against certain other co-defendants. In addition, a co-defendant
in the Tessera lawsuit requested the United States Patent and Trademark Office to reexamine the patentability of each of Tesseras patents that are at issue in the case in the California court. The requests were granted and, in February 2007,
the U.S. Patent and Trademark Office concluded that certain claims of the patents were invalid on the basis of prior art. In April 2008, ChipMOS Bermuda, ChipMOS USA and ChipMOS Taiwan received notice that Tessera requested the ITC to initiate
another investigation alleging that the sale for and after importation into the United States as well as importation into the United States of certain small format non-tape based BGA semiconductor packages by ChipMOS Bermuda, ChipMOS Taiwan and
ChipMOS USA infringe three of the five Tessera patents at issue in the case pending in the California court. Tessera sought, among other things, an investigation by the ITC and general exclusion orders to prohibit the infringing products from entry
into the United States. The ITC initiated the investigation in May 2008. On March 13, 2009, after the close of discovery, Tessera submitted a request to terminate the proceedings at the ITC, which the judge granted on July 17, 2009. No
petitions for review were filed. The ITC issued an order to terminate the investigation on August 7, 2009. The stayed litigations in the Northern District of California and the Eastern District of Texas may resume once the ITC completes a
companion investigation against other companies. Our counsel has not formed an opinion as to the outcome of the case.

In
September 2007, ChipMOS and ChipMOS Taiwan filed five lawsuits against Walton Advanced Engineering, Inc. and Walton Chaintech Corporation in Taiwan Kaohsiung District Court and Taiwan Banciao District Court, alleging infringement by these two
companies of ChipMOS Taiwans package related patents for SDRAM, DDR I SDRAM and DDR II SDRAM devices. ChipMOS and ChipMOS Taiwan have reached an official settlement agreement with Walton Advanced Engineering, Inc. and Walton Chaintech
Corporation on April 29, 2010 to withdraw all the patent infringement lawsuits and invalidation complaints between each other without any condition related to compensation.

In April 1999, Motorola, Inc. (Motorola) and ChipMOS Taiwan entered into an immunity agreement (the Agreement)
whereby each party covenanted not to sue each other for the use of certain Ball Grid Array (BGA) patents. In December 2004, Motorola spun off its semiconductor division, and thereby formed Freescale Semiconductor, Inc.
(Freescale), who then assumed Motorolas rights and obligations under the Agreement. On October 16, 2006, Freescale unilaterally terminated the Agreement, alleging that ChipMOS Taiwan breached the Agreement. ChipMOS Taiwan
argued that Freescales unilateral termination of the Agreement has no legal effect, and continues to accrue royalty payments for products it believes are covered by the Agreement. The payments previously returned by Freescale and accrued by
ChipMOS Taiwan have been deposited in a separate escrow account. On July 13, 2009, Freescale alleged that ChipMOS Taiwan breached the Agreement by failing to pay royalties on certain BGA packages assembled by ChipMOS Taiwan. ChipMOS Taiwan
filed an answer to deny all allegations, and also filed counterclaims against Freescale alleging that Freescale engaged in patent misuse by seeking to obtain royalties on certain of ChipMOS Taiwans BGA products that were not covered by any
Freescale patent included under the Agreement, and for declaratory judgment of patent non-infringement and invalidity. On December 11, 2009, Freescale filed a motion to dismiss the declaratory judgment counterclaims filed by ChipMOS Taiwan and
to stay all other patent related claims and issues until its breach of contract claims could be decided. That motion and the initial case management conference were held on March 5, 2010 and the motions were deemed submitted. A further case
management conference is schedule for June 11, 2010. As of March 31, 2010, no trial date has been scheduled. The Companys counsel has not formed any opinion as to the outcome of the case.

Pursuant to the long-term service agreement we have entered into with Spansion in September
2005, Spansion agreed to provide ChipMOS with six month rolling forecast on testing and assembly service orders to be placed to us. In January 2009, Spansion has defaulted on its payment obligations under the long-term service agreement and ChipMOS
has subsequently terminated the long-term service agreement with Spansion on February 19, 2009. On March 1, 2009, Spansion has filed for a voluntary petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code. On
January 25, 2010, ChipMOS Taiwan entered into a Transfer of Claim Agreement to sell to Citigroup the general unsecured claim reflected in the proof of claim against Spansion filed by ChipMOS Taiwan in U.S. Bankruptcy Court. In February 2010, we
received payment of approximately US$33 million from an escrow agent for the sale of accounts receivable for testing and assembly services provided to Spansion in the amount of approximately US$66 million to US$70 million, which was based the
Transfer of Claim Agreement. See Item 4. Information on the Company Customers.

On December 28, 2009,
Fulcrum Credit Partners LLC (Fulcrum) filed a complaint in Texas state court against ChipMOS Taiwan, ChipMOS USA and Citigroup alleging breach of contract, promissory estoppel, unjust enrichment and a claim for declaratory judgment,
arising from Fulcrums alleged oral agreement to purchase ChipMOS Taiwans claims against Spansion. ChipMOS Taiwan was not served, though ChipMOS USA was served. ChipMOS Taiwan was of the opinion that Fulcrum did not follow the proper
procedures and therefore ChipMOS Taiwan has no obligation to sell the claim to Fulcrum. On January 22, 2010, ChipMOS USA responded by removing the complaint to the U.S. District Court for the Western District of Texas. On January 29, 2010,
ChipMOS USA filed a motion to transfer venue to the Delaware Bankruptcy Court. Fulcrum filed its opposition to the transfer motion, and argument was held in the Western District of Texas. On February 17, 2010, Fulcrum filed an amended complaint
in federal court alleging breach of contract and unjust enrichment claims against ChipMOS Taiwan and ChipMOS USA. On March 3, 2010, ChipMOS USA moved for dismissal from federal court, asserting, inter alia, a complete defense in that the
alleged contract does not exist and, even if it did, ChipMOS USA was not a party, since ChipMOS Taiwan was not served with the amended complaint. Fulcrum filed its response to the motion to dismiss on March 15, 2010. As of March 31, 2010,
this lawsuit was pending.

Other than the matters described above, we were not involved in any material litigation in 2009 and
are not currently involved in any material litigation.

For certain information regarding legal proceedings relating to
certain of our current and former directors, see Item 3.Key InformationRisk FactorsRisks Related to Our BusinessThe ongoing criminal proceeding of and adverse publicity associated with Mr. Shih-Jye Cheng, our

|Item 10. | Additional Information
|-------- | ----------------------

Description of
Share Capital

Our authorized share capital consists of 250 million common shares, par value US$0.01 per share, and
75 million preferred shares, par value US$0.01 per share.

Common Shares

Each shareholder is entitled to one vote for each common share held on all matters submitted to a vote of shareholders. Cumulative voting
for the election of directors is not provided for in our bye-laws, which means that the holders of a majority of the shares voted can elect all of the directors then standing for election. The common shares are not entitled to preemptive rights and
are not subject to conversion or redemption. Upon the occurrence of a liquidation, dissolution or winding-up, the holders of common shares would be entitled to share ratably in the distribution of all of our assets remaining available for
distribution after satisfaction of all liabilities.

Preferred Shares

Currently there are no specific rights attached to the preferred shares. The specific rights of the preferred shares could include rights,
preferences or privileges in priority to our common shares and the establishment of such rights or the delegation to the board of directors to establish such rights will need to be approved by our shareholders. As of March 31, 2010, no
preferred shares have been issued by our company.

Bermuda Law

We are an exempted company organized under the Bermuda Companies Act. The rights of our shareholders are governed by Bermuda law and our
memorandum of association and bye-laws. The Bermuda Companies Act differs in some material respects from laws generally applicable to United States corporations and their shareholders.

Dividends

Under Bermuda law, a company may pay dividends that are declared from time to time by its board of directors unless there are reasonable
grounds for believing that the company is, or would after the payment be, unable to pay its liabilities as they become due or that the realizable value of its assets would thereby be less than the aggregate of its liabilities, issued share capital
and share premium accounts. The holders of common shares are entitled to receive dividends out of assets legally available for such purposes at times and in amounts as our board of directors may from time to time determine. Any dividend unclaimed
for a period of six years from its date of declaration will be forfeited and will revert to our company.

Voting Rights

Under Bermuda law, except as otherwise provided in the Bermuda Companies Act or our bye-laws, questions brought before a general meeting
of shareholders are decided by a majority vote of shareholders present at the meeting. Our bye-laws provide that, subject to the provisions of the Bermuda Companies Act, and except for extraordinary resolutions, any question properly proposed for
the consideration of the shareholders will be decided by a simple majority of the votes cast, either on a show of hands or on a poll, with each shareholder present (and each person holding proxies for any shareholder) entitled to one vote on a show
of hands, or on a poll, one vote for each fully paid-up common share held by the shareholder. In the case of an equality of votes cast, the chairman of the meeting shall have a second or casting vote. Any resolution for any of the following
extraordinary transactions will require the approval of shareholders holding at least 70.0% of the total voting rights of all the shareholders having the right to vote at such meeting:



| |  |  | a resolution for the merger, amalgamation or any other consolidation of us with any other company, wherever incorporated;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | a resolution for the sale, lease, exchange, transfer or other disposition of all or substantially all of our consolidated assets; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a resolution for the adoption of any plan or proposal for the liquidation of our company.
| | - |  | -----------------------------------------------------------------------------------------

Rights in Liquidation

Under Bermuda law, in the event of liquidation or winding-up of a company, after satisfaction in full of all claims of creditors and
subject to the preferential rights accorded to any series of preferred shares, the proceeds of the liquidation or winding-up are distributed pro rata in specie or in kind among the holders of our common shares in accordance with our bye-laws.

Meetings of Shareholders

Under Bermuda law, a company is required to convene at least one general shareholders meeting as an Annual General Meeting each
calendar year. Bermuda law provides that a special general meeting may be called by the board of directors and must be called upon the request of shareholders holding not less than 10% of the paid-up capital of the company carrying the right to
vote. Bermuda law also requires that shareholders be given at least five days advance notice of a general meeting but the accidental omission to give notice to any person does not invalidate the proceedings at a meeting. Under our bye-laws, we
must give each shareholder written notice at least five days prior to the annual general meeting, unless otherwise agreed by all shareholders having the right to vote at that annual general meeting, and written notice at least five days prior to any
special general meeting, unless otherwise agreed by a majority of shareholders having a right to vote at that special general meeting, and together holding at least 95% of the paid-up capital of the company carrying the right to vote at that
meeting.

Under Bermuda law, the number of shareholders constituting a quorum at any general meeting of
shareholders is determined by the bye-laws of the company. Our bye-laws provide that at least two shareholders present in person or by proxy and holding shares representing at least 50% of the total voting rights of all shareholders having the right
to vote at the meeting constitute a quorum. Our bye-laws further provide that, in respect of a general meeting adjourned for lack of quorum, at least two shareholders present in person or by proxy holding shares representing
331/3% of the total voting rights of all
shareholders having the right to vote at the meeting constitute a quorum.

Access to Books and Records and Dissemination of Information

Under Bermuda Law, members of the general public have the right to inspect the public documents of a company available at the office of
the Registrar of Companies in Bermuda. These documents include a companys certificate of incorporation, its memorandum of association (including its objects and powers), and any alteration to its memorandum of association and documents
relating to an increase or reduction of authorized capital. The shareholders have the additional right to inspect the bye-laws of the company, minutes of general meetings and the companys audited financial statements, which, unless agreed by
all shareholders and directors, must be laid before the annual general meeting. The register of shareholders of a company is also open to inspection by shareholders without charge and by members of the general public on the payment of a fee. A
company is required to maintain its share register in Bermuda but may, subject to the provisions of Bermuda law, establish a branch register outside Bermuda. We maintain a share register in Hamilton, Bermuda and a branch register in New Jersey, USA.
A company is required to keep at its registered office a register of its directors and officers which is open for inspection for not less than two hours each day by members of the public without charge. Bermuda law does not, however, provide a
general right for shareholders to inspect or obtain copies of any other corporate records.

Election or Removal of Directors

Under Bermuda law and our bye-laws, directors are elected or appointed at an annual general meeting and serve until
re-elected or re-appointed or until their successors are elected or appointed, unless they are earlier removed for cause or resign or otherwise cease to be directors under Bermuda law or our bye-laws.

A director may be removed for cause at a special general meeting of shareholders specifically called for that purpose, provided that the
director is served with at least 14 days notice. The director has a right to be heard at that meeting. Any vacancy created by the removal of a director at a special general meeting may be filled at that meeting by the election of another
director in his or her place or, in the absence of any election by the shareholders, by the board of directors.

Board Actions

Our bye-laws provide that the quorum necessary for the transaction of business is two directors of the board, and that
questions arising at a properly convened meeting of the board of directors must be approved by a majority of the votes present and entitled to be cast. In the case of an equality of votes, the chairman of the meeting is entitled to a second or
casting vote.

The board of directors may appoint any of our directors to act as our managing director or other senior
executive, on such terms and conditions as it may determine, including with respect to remuneration.

Amendment of Memorandum of
Association and Bye-laws

Bermuda law provides that the memorandum of association of a company may, with the consent of the
Minister of Finance of Bermuda (if required), be amended by a resolution passed at a general meeting of shareholders of which due notice has been given. Our bye-laws, other than the bye-law separating our board of directors into three classes, may
be amended by the board of directors if the amendment is approved by a majority of votes cast by our directors and by our shareholders by a resolution passed by a majority of votes cast at a general meeting. Any amendment to our bye-law separating a
board of directors into three classes must be approved by our board of directors and by shareholders of shares representing at least 60% of our outstanding shares.

Under Bermuda law, the holders of an aggregate of no less than 20% in par value of a companys issued share capital or any class of
issued share capital have the right to apply to the Bermuda Court for an annulment of any amendment of the memorandum of association adopted by shareholders at any general meeting, other than an amendment that alters or reduces a companys
share capital as provided in the Bermuda Companies Act. Where an application is made, the amendment becomes effective only to the extent that it is confirmed by the Bermuda Court. An application for the annulment of an amendment of the memorandum of
association must be made within 21 days after the date on which the resolution altering the companys memorandum of association is passed and may be made on behalf of the person entitled to make the application by one or more of their number as
they may appoint in writing for the purpose. No application may be made by persons voting in favor of the amendment.

Appraisal Rights and Shareholder Suits

Under Bermuda law, in the event of an amalgamation of two Bermuda companies, a shareholder who did not vote in favour of the amalgamation
and who is not satisfied that fair value has been paid for his or her shares may apply to the Bermuda Court to appraise the fair value of those shares. The Bermuda Companies Act provides that, subject to the terms of a companys bye-laws, the
amalgamation of a Bermuda company with another company requires the amalgamation agreement to be approved by the board of directors and, except where the amalgamation is between a holding company and one or more of its wholly-owned subsidiaries or
between two or more wholly-owned subsidiaries, by meetings of the holders of shares of each company and of each class of such shares at a meeting of the shareholders by seventy-five percent of the members present and entitled to vote at that meeting
in respect of which the quorum shall be two persons holding or representing at least one-third of the issued shares of each company or class, as the case may be. Under our bye-laws, any resolution proposed for consideration at any general meeting to
approve the merger, amalgamation or any other consolidation of our company with any other company, wherever incorporated shall require the approval of our shareholders holding shares representing at least 70% of the total voting rights of all our
shareholders, and the quorum to be at least 2 shareholders present in person or by proxy holdings hares representing at least 50% of the total voting rights of all the shareholders.

Under Bermuda law, an amalgamation also requires the consent of the Bermuda Minister of Finance, who may grant or withhold his consent at
his discretion.

Class actions and derivative actions are generally not available to shareholders under Bermuda law. The
Bermuda Court, however, would ordinarily be expected to permit a shareholder to commence an action in the name of a company to remedy a wrong done to the company where the act complained of is alleged to be beyond the corporate power of the company
or is illegal or would result in the violation of the companys memorandum of association or bye-laws. Further consideration would be given by the Bermuda Court to acts that are alleged to constitute a fraud against the minority shareholders
or, for instance, where an act requires the approval of a greater percentage of the companys shareholders than that which actually approved it.

When the affairs of a company are being conducted in a manner oppressive or prejudicial to the interests of some part of the
shareholders, one or more shareholders may apply to the Bermuda Court for an order regulating the companys conduct of affairs in the future or compelling the purchase of the shares by any shareholder, by other shareholders or by the company.

Exchange Controls

The following discussion is based on the advice of Appleby, our Bermuda counsel.

The BMA, has designated us as non-resident for exchange control purposes. The BMA has granted its consent under the Exchange Control Act
1972 and regulations promulgated thereunder for the issue or transfer to non-residents of Bermuda for exchange control purposes of our common shares, subject to the common shares remaining quoted on the NASDAQ Capital Market.

Share Issuance and Transfers by Non-Bermuda and Bermuda Residents

Under Bermuda law, there are no limitations on the rights of non-Bermuda residents to hold or vote their shares of Bermuda companies.
Because we have been designated as a non-resident for Bermuda exchange control purposes, there are no restrictions on our ability to transfer funds in and out of Bermuda or to pay dividends to United States residents who are holders of our common
shares other than in respect of local Bermuda currency.

Under Bermuda law, we are an exempted company. An exempted company is
exempt from the provisions of Bermuda law, which stipulate that at least 60% of the equity must be beneficially owned by Bermuda persons. Persons regarded as residents of Bermuda for exchange control purposes require specific consent under the
Exchange Control Act 1972 to acquire securities issued by us. The Exchange Control Act 1972 permits companies to adopt bye-law provisions relating to the transfer of securities. None of Bermuda law, our memorandum of association or our bye-laws
imposes limitations on the right of foreign nationals or non-residents of Bermuda to hold our shares or vote such shares.

As
an exempted company, we may not participate in certain business transactions, including: (1) the acquisition or holding of land in Bermuda, except (i) land acquired for its business by way of lease or tenancy agreement for a term not
exceeding fifty years, or (ii) with the consent of the Minister of Finance granted in his discretion, land by way of lease or tenancy agreement for a term not exceeding twenty-one years in order to provide accommodation or recreational
facilities for its officers and employees; (2) the taking of mortgages on land in Bermuda to secure an amount in excess of US$50,000 without the consent of the Bermuda Minister of Finance; or (3) the carrying on of business of any kind in
Bermuda, except in furtherance of our business carried on outside Bermuda or under a license granted by the Bermuda Minister of Finance. In addition, present BMA policy permits no more than 20% of the share capital of an exempted company to be held
by Bermuda persons.

##### Table of Contents

The Bermuda government actively encourages foreign investment in exempted entities like us
that are based in Bermuda but do not operate in competition with local business. In addition to having no restrictions on the degree of foreign ownership, we are subject neither to taxes on our income or dividends nor to any foreign exchange
controls in Bermuda. In addition, there is no capital gains tax in Bermuda, and profits can be accumulated by us without limitation.

Directors Interests

Under the Bermuda Companies Act, a director of a company may, notwithstanding his office, be a party to or otherwise interested in any
transaction or arrangement with the company or in which the company is otherwise interested. He or she may also be a director or officer of, or employed by, or a party to any transaction or arrangement with, or otherwise interested in, any corporate
body promoted by the same company or an interested company. Therefore, where it is necessary, so long as a director of a Bermuda company declares the nature of his or her interest at the first opportunity at a meeting of the board or by writing to
the directors as required by the Bermuda Companies Act, that director shall not by reason of his or her office be accountable to a company for any benefit he or she derives from any office or employment to which the bye-laws of the company allow him
or her to be appointed or from any transaction or arrangement in which the bye-laws of such company allow him or her to be interested, and no such transaction or arrangement shall be liable to be avoided on the ground of any such interest or
benefit. A general notice to the directors by a director or officer declaring that he or she is a director or officer or has an interest in a person and is to be regarded as interested in any transaction or arrangement made with that person shall be
sufficient declaration of interest in relation to any transaction or arrangement so made.

Share Issuance and Transfer

We have been designated as a non-resident for exchange control purposes by the BMA, whose permission for the issuance and
transfer of common shares has been obtained subject to the common shares being quoted on the NASDAQ Capital Market.

The
transfer of common shares between persons regarded as non-resident in Bermuda for exchange control purposes and the issuance of shares after the completion of the currently contemplated offering of our common shares to those persons may be effected
without specific consent under the Exchange Control Act 1972 of Bermuda and regulations thereunder subject to the common shares remaining quoted on the NASDAQ Capital Market. Issuance and transfer of shares to any person regarded as resident in
Bermuda for exchange control purposes require specific prior approval under the Exchange Control Act 1972.

There are no
limitations on the rights of persons regarded as non-residents of Bermuda for foreign exchange control purposes who own common shares to hold or vote their common shares. Since we have been designated as a non-resident for Bermuda exchange control
purposes, there are no restrictions on our ability to transfer funds in and out of Bermuda or to pay dividends to United States residents or other non-residents of Bermuda who are holders of common shares, other than in respect of local Bermuda
currency. Furthermore, it is not our intent to maintain Bermuda dollar deposits and, accordingly, will not pay dividends on the common shares in Bermuda currency.

Bermuda law requires that share certificates be issued only in the names of corporations or individuals. Where an applicant for common
shares acts in a special capacity, such as an executor or trustee, certificates may, at the request of that applicant, record the capacity in which the applicant is acting. Our recording of any special capacity, however, shall not be construed as
obliging us either to investigate, or to incur any responsibility or liability in respect of, the proper administration of any trust or estate. Regardless of whether or not we have had notice of a trust, no notice shall be taken of any trust,
equitable, contingent, future or partial interest in any share or any interest in any fractional part of a share or any other right in respect of any common shares.

Transfer Agent and Registrar

Appleby Management (Bermuda) Ltd. (formerly known as Reid Management Limited) serves as our principal registrar and transfer agent in
Bermuda for the common shares. Mellon Investor Services, LLC serves as our United States transfer agent and registrar for the common shares.

Bermuda Taxation

This summary is based on laws, regulations, treaty provisions and interpretations now in effect and available as of the date of this
Annual Report on Form 20-F. The laws, regulations, treaty provisions and interpretations, however, may change at any time, and any change could be retroactive to the date of issuance of our common shares. These laws, regulations and treaty
provisions are also subject to various interpretations, and the relevant tax authorities or the courts could later disagree with the explanations or conclusions set out below.

At the date hereof, there is no Bermuda income, corporation or profits tax, withholding tax, capital gains tax, capital transfer tax,
estate duty or inheritance tax payable by us or our shareholders other than shareholders ordinarily resident in Bermuda. We are not subject to stamp or other similar duty on the issuance, transfer or redemption of our common shares.

We have obtained an assurance from the Minister of Finance of Bermuda under the Exempted Undertaking Tax Protection Act 1966 that, in the
event there is enacted in Bermuda any legislation imposing tax computed on profits or income or computed on any capital assets, gain or appreciation or any tax in the nature of estate duty or inheritance tax, such tax shall not be applicable to us
or to our operations, or to the common shares, debentures or our other obligations until March 28, 2016, except insofar as such tax applies to persons ordinarily resident in Bermuda and holding such common shares, debentures or our other
obligations or any real property or leasehold interests in Bermuda owned by us. No reciprocal income tax treaty affecting us exists between Bermuda and the United States.

As an exempted company, we are liable to pay in Bermuda an annual registration fee calculated on a sliding scale basis by reference to
our assessable capital, which is the aggregate of our authorized common share capital and the premium on our issued common shares currently at a rate not exceeding US$31,120 per annum.

United States Federal Income Taxation

In General

This section describes the material United States federal income tax consequences generally applicable to ownership by a U.S. holder (as
defined below) of our common shares. It applies to you only if you hold your common shares as capital assets for tax purposes. This section does not apply to you if you are a member of a special class of holders subject to special rules, including:



| |  |  | a dealer in securities;
| | - |  | -----------------------



| |  |  | a trader in securities that elects to use a mark-to-market method of accounting for securities holdings;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | a tax-exempt organization;
| | - |  | --------------------------



| |  |  | a life insurance company;
| | - |  | -------------------------



| |  |  | a person liable for alternative minimum tax;
| | - |  | --------------------------------------------

##### Table of Contents

| |  |  | a person that actually or constructively owns 10% or more of our voting stock;
| | - |  | ------------------------------------------------------------------------------



| |  |  | a person that holds common shares as part of a straddle or a hedging or conversion transaction; or
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | a person whose functional currency is not the US dollar.
| | - |  | --------------------------------------------------------

This section is based on the Internal Revenue Code of 1986, as amended, its legislative history, existing and proposed regulations,
published rulings and court decisions all as currently in effect. These laws are subject to change, possibly on a retroactive basis. There is currently no comprehensive income tax treaty between the United States and Bermuda.

You are a U.S. holder if you are a beneficial owner of common shares and you are:



| |  |  | a citizen or resident of the United States;
| | - |  | -------------------------------------------



| |  |  | a domestic corporation;
| | - |  | -----------------------



| |  |  | an estate whose income is subject to United States federal income tax regardless of its source; or
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | a trust if a United States court can exercise primary supervision over the trusts administration and one or more United States persons are
authorized to control all substantial decisions of the trust.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If a partnership holds the common shares, the
United States federal income tax treatment of a partner will generally depend on the status of the partner and the tax treatment of the partnership. If you hold the common shares as a partner in a partnership you should consult your tax advisor with
regard to the United States federal income tax treatment of an investment in the common shares.

You should consult your own
tax advisor regarding the United States federal, state and local and the Bermuda and other tax consequences of owning and disposing of common shares in your particular circumstances.

This discussion addresses only United States federal income taxation.

Taxation of Dividends

Under the United States federal income tax laws, and subject to the passive foreign investment company, or PFIC, rules discussed below, if
you are a U.S. holder, the gross amount of any dividend we pay out of our current or accumulated earnings and profits (as determined for United States federal income tax purposes) is subject to United States federal income taxation. If you are a
noncorporate U.S. holder, dividends paid to you in taxable years beginning before January 1, 2011 that constitute qualified dividend income will be taxable to you at a maximum tax rate of 15% provided that you hold the common shares for more
than 60 days during the 121-day period beginning 60 days before the ex-dividend date and meet other holding period requirements. Dividends we pay with respect to the common shares generally will be qualified dividend income provided that, in the
year that you receive the dividend, the common shares are readily tradable on an established securities market in the United States. We believe that our shares, which are listed on the NASDAQ, are readily tradable on an established securities market
in the United States; however, there can be no assurance that our shares will continue to be readily tradable on an established securities market.

The dividend is taxable to you when you receive the dividend, actually or constructively. The dividend will not be eligible for the
dividends-received deduction generally allowed to United States corporations in respect of dividends received from other United States corporations. Distributions in excess of current and accumulated earnings and profits, as determined for United
States federal income tax purposes, will be treated as a non-taxable return of capital to the extent of your basis in the common shares and thereafter as capital gain.

Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to the maximum 15% tax
rate.

Dividends will be income from sources outside the United States, but dividends paid in taxable years beginning before
January 1, 2007 generally will be passive or financial services income, and dividends paid in taxable years beginning after December 31, 2006 will, depending on your circumstances, be passive or
general income which, in either case, is treated separately from other types of income for purposes of computing the foreign tax credit allowable to you. You should consult your own tax advisor regarding the foreign tax credit rules.

Taxation of Capital Gains

Subject to the PFIC rules discussed below, if you are a U.S. holder and you sell or otherwise dispose of your common shares, you will
recognize capital gain or loss for United States federal income tax purposes equal to the difference between the amount that you realize and your tax basis in your common shares. Capital gain of a noncorporate U.S. holder that is recognized in
taxable years beginning before January 1, 2011 is generally taxed at a maximum rate of 15% where the holder has a holding period greater than one year. The deductibility of capital losses is subject to limitations. The gain or loss will
generally be income or loss from sources within the United States for foreign tax credit limitation purposes.

PFIC Rules. We
believe that our common shares should not be treated as stock of a Personal Foreign Investment Company, or PFIC, for United States federal income tax purposes, but this conclusion is a legal and factual determination that is made annually and thus
may be subject to change. If we were to be treated as a PFIC, unless a U.S. holder elects to be taxed annually on a mark-to-market basis with respect to the shares, gain realized on the sale or other disposition of your common shares would in
general not be treated as capital gain. Instead, if you are a U.S. holder, you would be treated as if you had realized such gain and certain excess distributions ratably over your holding period for the common shares and would not
be taxed at the highest tax rate in effect for each such year to which the gain was allocated, together with an interest charge in respect of the tax attributable to each such year. With certain exceptions, your common shares will be treated as
stock in a PFIC if we were a PFIC at any time during your holding period in your common shares. Dividends that you receive from us will not be eligible for the special tax rates applicable to qualified dividend income if we are treated as a PFIC
with respect to you either in the taxable year of the distribution or the preceding taxable year, but instead will be taxable at rates applicable to ordinary income.

|Item 11. | Quantitative and Qualitative Disclosure about Market Risk
|-------- | ---------------------------------------------------------

Market Risks

Our
exposure to financial market risks relates primarily to changes in interest rates and foreign exchange rates. To mitigate these risks, we utilize derivative financial instruments, the application of which is primarily for hedging, and not for
speculative, purposes.

Interest Rate Risks

As of December 31, 2009, we had aggregate debt outstanding of NT$18,116 million (US$567 million), which was incurred for capital
expenditure and general operating expenses. Of our outstanding debt as of December 31, 2009, 83% bears interest at variable rates. The interest rate for the majority of our variable rate debt varies based on a fixed percentage spread over the
prime rate established by our lenders. Our variable rate debt had an annual weighted average interest rate of 2.4% as of December 31, 2009. Accordingly, we have cash flow and earnings exposure due to market interest rate changes for our
variable rate debt. An increase in interest rates of 1% would increase our annual interest charge by NT$150 million (US$5 million) based on our outstanding indebtedness as of December 31, 2009.

As of December 31, 2008 and 2009, ChipMOS Taiwan had no interest rate swap agreements outstanding. ChipMOS Taiwan had entered into
five interest rate swap agreements during the year of 2004 and 2005. On October 4, 2005, ChipMOS Taiwan terminated the swap with a notional amount of NT$300 million, which was entered into on October 13, 2004, and entered into two interest
rate swap agreements each with a notional amount of NT$100 million, which were terminated on November 8, 2005 and December 5, 2005, respectively. On November 2, 2005, ChipMOS Taiwan entered into an interest rate swap agreement with a
notional amount of NT$200 million, which was terminated on November 4, 2005. On November 4, 2005, the swap with a notional amount of NT$500 million, which was entered into on July 28, 2004, was also terminated. For these swaps, the
difference in interest rates is calculated quarterly and credited or charged in the current period. In 2005, we recognized as NT$11 million of non-operating expense as a result of the swaps.

Foreign Currency Exchange Rate Risks

Our foreign currency exposure gives rise to market risks associated with exchange rate movements against the NT dollar, the Japanese yen
and the US dollar. As of December 31, 2009, 59% of our accounts receivable are denominated in US dollars and Japanese yen, and 23% of our accounts payable and payables for properties are denominated in Japanese yen and US dollars. To minimize
foreign currency exchange risk, from time to time we utilize forward exchange contracts and foreign currency options to hedge our exchange rate risk on foreign currency assets or liabilities positions. These hedging transactions help to reduce, but
do not eliminate, the impact of foreign currency exchange rate movements. An average depreciation of the NT dollar against all other relevant foreign currencies of 5% would increase our annual exchange loss by NT$79 million (US$2 million) based on
our outstanding assets and liabilities denominated in foreign currencies as of December 31, 2009. As of December 31 2007, 2008 and 2009, we had no outstanding forward exchange or foreign currency option contracts. Our net gains on forward
exchange contracts were NT$123 thousand, nil and nil for the years ended December 31, 2007, 2008 and 2009, respectively.

See Note 24 of our audited consolidated financial statements for additional information on these derivative transactions.

Managements Report on Internal Control Over Financial Reporting

June 4, 2010

Management
of ChipMOS TECHNOLOGIES (Bermuda) LTD. (together with its consolidated subsidiaries, the Company) is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(e) of the
Securities Exchange Act of 1934). The Companys internal control over financial reporting is a process designed under the supervision of the Companys chief executive officer and chief financial officer to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of the Companys financial statements for external reporting purposes in accordance with generally accepted accounting principles in the Republic of China and the required
reconciliation to generally accepted accounting principles in the United States.

As of December 31, 2009, the
Companys management, with the participation of the Companys chief executive officer and chief financial officer, conducted an assessment of the effectiveness of the Companys internal control over financial reporting using criteria
set forth in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, the Companys management has concluded that the Companys internal
control over financial reporting as of December 31, 2009 was effective.

Moore Stephens, an independent registered public
accounting firm, has audited our consolidated financial statements included in the Annual Report of the Company on Form-20F for the year ended December 31, 2009 and has issued an attestation report on the Companys internal control over
financial reporting as of December 31, 2009. The attestation report is set forth in Item 18. Financial Statements.

governance requirements applicable to NASDAQ-listed foreign private issuers under NASDAQ listing rules.

Under NASDAQ Rule
5615(a)(3), NASDAQ-listed foreign private issuers may, in general, follow their home country corporate governance practices instead of most NASDAQ corporate governance requirements. However, all NASDAQ-listed, foreign private issuers must comply
with NASDAQ Rules 5605(c)(2)(A)(ii), 5605(c)(3), 5625 and 5640.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders

ChipMOS TECHNOLOGIES (Bermuda) LTD.

We have
audited the accompanying consolidated balance sheets of ChipMOS TECHNOLOGIES (Bermuda) LTD. and subsidiaries (collectively, the Company) (see Note 1) as of December 31, 2009 and 2008, and the related consolidated statements of
operations, changes in equity, and cash flows for each of the three years in the period ended December 31, 2009, all expressed in New Taiwan dollars. We have also audited the Companys internal control over financial reporting as of
December 31, 2009, based on criteria established in Internal Control  Integrated Framework issued by the Treadway Commission (COSO). The Companys management is responsible for these financial statements, for maintaining effective
internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Managements Report on Internal Control Over Financial Reporting. Our
responsibility is to express an opinion on these consolidated financial statements and an opinion on the Companys internal control over financial reporting based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the Republic of China and 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 consolidated financial statements are free of material misstatement and whether effective
internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements,
assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of
internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such
other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A
companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect
the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of
unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the 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.

Report of Independent Registered Public Accounting Firm (continued)



In our opinion, the consolidated financial statements referred to above present fairly, in all material
respects, the consolidated financial position of the Company as of December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2009, in conformity with
accounting principles generally accepted in the Republic of China. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on criteria
established in Internal Control  Integrated Framework issued by the Treadway Commission (COSO).

Accounting principles generally
accepted in the Republic of China vary in certain significant respects from accounting principles generally accepted in the United States of America. The application of the latter would have affected the determination of net income for each of the
three years in the period ended December 31, 2009, and the determination of equity and financial position at December 31, 2009 and 2008, to the extent summarized in Note 26.

ChipMOS TECHNOLOGIES (Bermuda) LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



|1. | ORGANIZATION AND BUSINESS
|-- | -------------------------

ChipMOS TECHNOLOGIES (Bermuda) LTD. (ChipMOS Bermuda) was incorporated under the laws of Bermuda on August 1, 2000, and its common
shares have been traded on the NASDAQ Global Select Market since June 2001. As of December 31, 2009, ChipMOS Bermuda was 13.33% and 14.50% owned by Mosel Vitelic Inc. (MVI) through its wholly-owned subsidiary, Giant Haven Investment Ltd. and
its indirectly-owned subsidiary, Mou-Fu Investment Ltd. (Mou-Fu) and Siliconware Precision Industries Co. Ltd (SPIL). As of December 31, 2009, ChipMOS Bermuda owned 100% (2008: 100%) of the outstanding common shares of ChipMOS TECHNOLOGIES INC.
(ChipMOS Taiwan).

LOGO

ChipMOS Taiwan was incorporated in Taiwan on July 28, 1997 as a joint venture company between MVI and
SPIL. Its operations consist of testing and assembly of semiconductors. In connection with a corporate restructuring on January 12, 2001, the holders of an aggregate of 583,419 thousand common shares of ChipMOS Taiwan executed a Purchase
and Subscription Agreement whereby they transferred their shares of ChipMOS Taiwan to ChipMOS Bermuda in exchange for 58,342 thousand common shares in ChipMOS Bermuda. The selling shareholders, who previously held an aggregate of 70.25% of the
entire outstanding common shares of ChipMOS Taiwan, thus became the holders of the entire outstanding common shares of ChipMOS Bermuda. Because 100% of the outstanding common shares of ChipMOS Bermuda were owned by former shareholders of ChipMOS
Taiwan, the exchange of shares has been accounted for as a merger as if ChipMOS Bermuda was the acquirer. Equity and operations attributable to ChipMOS Taiwan shareholders not participating in the exchange offer were reflected as noncontrolling
interest in the historical financial statements. In March 2007, ChipMOS Bermuda, ChipMOS Taiwan and SPIL completed a share purchase and subscription transaction whereby ChipMOS Bermuda purchased 100% of SPILs equity interest in ChipMOS Taiwan
at US$0.75 per share. SPIL also subscribed to 12,174,998 newly issued common shares of ChipMOS Bermuda through a private placement of US$6.28 per share. After the transaction, ChipMOS Taiwan became a 99.14% subsidiary of ChipMOS Bermuda and SPIL
owned 14.7% of ChipMOS Bermuda. In September 2007, another share exchange transaction was completed whereby ChipMOS Bermuda offered to exchange one share of ChipMOS Bermuda for 8.4 shares of ChipMOS Taiwan shares. The exchange was completed in
September 2007 and ChipMOS Taiwan became a wholly-owned subsidiary of ChipMOS Bermuda. As of December 31, 2009, ChipMOS Bermuda held a 100% interest in ChipMOS Taiwan.

ThaiLin Semiconductor Corp. (ThaiLin) was incorporated on May 15, 1996 and is listed on the GreTai Securities Market in Taiwan.
ThaiLin is engaged in wafer and semiconductor testing services. On December 31, 2002, ChipMOS Taiwan acquired an equity interest of 41.8% in ThaiLin. On December 1, 2003, ChipMOS Taiwan obtained controlling influence over ThaiLins
decisions on its operations, personnel and financial policies. Therefore, ThaiLin has been consolidated into these financial statements from December 1, 2003 in spite of the fact that ChipMOS Taiwan holds an equity interest of less than 50% in
ThaiLin. As of December 31, 2009, ChipMOS Taiwan held a 42.87% equity interest in ThaiLin.

ChipMOS Japan Inc. (ChipMOS
Japan) was incorporated in Japan in June 1999, and ChipMOS USA Inc. (ChipMOS USA) was incorporated in the United States of America in October 1999. These two companies engage in sales and customer services and all the expenses incurred from these
activities are charged to current income. ChipMOS Japan began generating revenue in 2000, while ChipMOS USA began generating revenue in 2001. As of December 31, 2009, ChipMOS Taiwan owned 100% of the outstanding shares of ChipMOS USA. ChipMOS
Japan was liquidated in October 2009.

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



MODERN MIND TECHNOLOGY LIMITED (Modern Mind) was incorporated in the British Virgin
Islands on January 29, 2002. Modern Mind conducts its operations through ChipMOS TECHNOLOGIES (Shanghai) LTD. (ChipMOS Shanghai). ChipMOS Bermuda acquired a 100% equity interest in Modern Mind on December 12, 2002, and then transferred it
to Jesper Limited (Jesper) on December 31, 2002. In December 2002 and 2003, ChipMOS Bermuda acquired from Jesper and ChipMOS Taiwan, respectively, convertible notes issued by Modern Mind that are convertible into a controlling equity interest
in Modern Mind if the repayment is not made when due. Accordingly, ChipMOS Bermuda is deemed to have a controlling interest in Modern Mind.

ChipMOS Shanghai a wholly-owned subsidiary of Modern Mind, was established in the Peoples Republic of China (PRC) on June 7,
2002. ChipMOS Shanghai is engaged in wafer testing, semiconductor assembly and testing, and module and subsystem manufacturing. ChipMOS Shanghai commenced commercial production in 2003.

ChipMOS Bermuda controls both Modern Mind and its 100% subsidiary, ChipMOS Shanghai, as ChipMOS Bermuda possesses the power to direct or
cause the direction of the management and policies of Modern Mind by contract or otherwise and thereby has established a parent-subsidiary relationship over Modern Mind and ChipMOS Shanghai. For this reason, Modern Mind and ChipMOS Shanghai have
been consolidated into these financial statements in spite of the fact that ChipMOS Bermuda does not hold an equity interest in Modern Mind.

ChipMOS TECHNOLOGIES (H.K.) Limited (ChipMOS HK) was incorporated in Hong Kong on November 18, 2002. It is engaged in semiconductor
testing and assembly services and trading of spare parts and tools. ChipMOS HK is a wholly-owned subsidiary of ChipMOS Bermuda.

Basis of presentation

The consolidated financial statements include the accounts of ChipMOS Bermuda and all subsidiaries in which ChipMOS Bermuda (hereinafter,
referred to individually or collectively as the Company) holds a controlling interest or voting interests in excess of 50% in accordance with the requirements of ROC Statement of Financial Accounting Standards (SFAS
No. 7). All significant intercompany accounts and transactions have been eliminated.

The Companys
consolidated financial statements include for 2007, 2008 and 2009, the financial results of ChipMOS Taiwan and its subsidiaries, ThaiLin, ChipMOS Japan and ChipMOS USA, ChipMOS HK and Modern Mind and its wholly-owned subsidiary, ChipMOS Shanghai.

Adoption of revised ROC SFAS

Effective January 1, 2009, the Company adopted the newly revised SFAS No. 10, Accounting for Inventories. (SFAS
No. 10R) The main revisions are (1) inventories are stated at the lower of cost or net realizable value, and inventories are written down to net realizable value on an item-by-item basis except when the grouping of similar or related items
is appropriate; (2) unallocated overheads are recognized as expenses in the year in which they are incurred; and (3) abnormal cost, write-downs of inventories and any reversal of write-downs are recorded as cost of sales for the year. Such
changes increased cost of revenue by NT$68,334 thousand, which represented an increase in allowance of inventories of NT$68,574 thousand net of a decrease of fixed manufacturing costs of NT$240 thousand.

Concentration of credit risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, accounts and other
receivables.

At December 31, 2009, the Company had credit risk exposure of uninsured cash in banks of approximately
NT$4,128,677 thousand (US$129,223 thousand).

A substantial portion of revenue is earned from a small number of customers on
credit and generally without any requirement of collateral.

The Company had two and one customers that had balances greater
than ten percent of total notes and accounts receivable as of December 31, 2008 and 2009, respectively:



|                        |  |              |  |

|Spansion LLC (Spansion) |  | 41%          |  | 46% 

Full allowance was made
against all receivables from ProMOS and Spansion in 2008 and 2009.

Credit evaluation of each customer is performed and
reserves for potential credit losses are maintained.

Use of estimates

The preparation of consolidated financial statements requires management to make estimates and judgments that affect the recorded amounts
of assets, liabilities, revenue and expenses of the Company. The Company continually evaluates these estimates, including those related to allowances for doubtful amounts, inventories, useful lives of properties, income tax valuation allowances,
pension plans and the fair value of financial instruments. The Company bases its estimates on historical experience and other assumptions, which it believes to be reasonable under the circumstances. Actual results may differ from these estimates
under different assumptions and conditions.

Cash equivalents

Repurchase notes with original maturity dates of three months or less are classified as cash equivalents.

Financial assets/liabilities at fair value through profit and loss

Financial assets and liabilities at fair value through profit and loss include investments and liabilities held for trading purposes and
those designated as financial assets/liabilities reported at fair value. Transaction costs directly attributable to the acquisition or issuance of these financial assets and liabilities are expensed immediately as incurred. Subsequent to initial
recognition, financial assets and liabilities are remeasured at fair value and the changes shall be recognized in earnings.

Held-to-maturity investments and investments with no active market

Held-to-maturity investments and investments with no active market are carried at amortized cost using the effective interest method. The
Company assesses at each balance sheet date whether there is any objective evidence that the investments are impaired. If there is objective evidence that an impairment loss has been incurred, the amount of the loss is recognized and measured as the
difference between the investments carrying amount and the present value of estimated future cash flows discounted at the investments original effective interest rate. The carrying amount of the investment shall be reduced either
directly or through use of an allowance account. The amount of the loss shall be recognized in profit or loss.

If, in a
subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the previously recognized impairment loss shall be reversed either directly or by
adjusting an allowance account. The reversal shall not result in a carrying amount of the investment that exceeds what the amortized cost would have been had the impairment not been recognized at the date the impairment is reversed. The amount of
the reversal shall be recognized in profit or loss.

Allowance for doubtful receivables

The allowance for doubtful receivables reflects estimates of the expected amount of the receivables that the Company will not be able to
collect. The Company first examines the available information regarding any customer that the Company has reason to believe may be unable to meet its financial obligations. For these customers, the Company uses its judgment, based on the available
facts and circumstances, and records a specific allowance for that customer against amounts due to reduce the receivable to the amount that is expected to be collected. These specific allowances are reevaluated and adjusted as additional information
is received. Secondly, for all other customers, the Company maintains an allowance based on a range of percentages applied to aging categories. These percentages are based on our historical collection and write-off experience. Additional allowances
may be required in the future if the financial condition of our customers or general economic conditions deteriorate, and this additional allowance would reduce the Companys net income.

Allowances for sales returns and discounts

Allowances for sales returns and discounts are provided based on the sales returns from past experience; such provisions are deducted from
sales and the related costs of products are deducted from cost of products sold.

Inventories

Inventories are stated at the lower of standard cost (which adjusted to approximate weighted average cost on the balance sheet date) or
net realizable value. Inventory write-down is made on an item-by-item basis, except where it may be appropriate to group similar or related items. Net realizable value is the estimated selling price of inventories less all estimated costs of
completion and necessary selling costs. Prior to January 1, 2009, inventories were stated at the lower of cost or market value. Any write-down was made on a total-inventory basis. Market value represented replacement cost for raw materials and
net realizable value for finished goods and work in progress.

Long-term investments

Investments in shares of stock of companies wherein the Company exercises significant influence on operational or financial decisions are
accounted for using the equity method. Under the equity method, the investments are initially carried at cost and subsequently adjusted for the proportionate equity of the Company in the net income or net loss of the investees.

The Company will discontinue its recognition of its equity in the net loss of the investees when the carrying value of the investment
(including advances) is reduced to zero. However, in cases where the Company guarantees the obligations or is committed to provide further financial support to an investee, or if the investees losses are temporary and evidence sufficiently
shows imminent return to profitability in the foreseeable future, then the Company continues to recognize its share in the net loss of the investees. (The resulting credit balances of the long-term investments are presented as part of other
receivables from related parties.)

Translation adjustments resulting from the process of translating the investees
financial statements into the functional currency of the Company are recorded as cumulative translation adjustments in the statement of changes in equity.

Property, plant and equipment and employee dormitory buildings

Property, plant and equipment and employee dormitory buildings (presented as part of Other Assets) are stated at cost less accumulated
depreciation. Major additions, renewals and improvements are capitalized while maintenance and repairs are expensed as incurred.

The initial estimate of the service lives of property, plant and equipment is as follows: machinery and equipment, 1 to 5 years; buildings
and auxiliary equipment, 1 to 54 years; furniture and fixtures, 1 to 5 years; tooling, 1 to 2 years; transportation equipment, 5 years; and leasehold improvements, the lower of lease term or 1 to 10 years. Salvage value is considered when
determining the basis of depreciated assets. If items of property, plant and equipment and employee dormitory buildings are still in good condition and useful at the end of their original service lives, the salvage value is depreciated over any
extended useful life.

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

Leased assets

Assets under capital leases are recorded at the lower of the fair value of the leased assets and the present value of the minimum lease
payments of such assets. The leased assets are depreciated over the shorter of lease terms or the estimated useful life of the leased assets.

Intangible assets

Intangible assets are recorded at cost except for donation from the government, which is measured at fair value. Subsequent to their
initial recognition, the book values are the cost and their incremental value that resulted from revaluation minus accumulated amortization and impairment loss.

Amortization is computed using the straight-line method. The Company reevaluates the residual value, estimated useful lives, and
amortization method at least once every year. Changes in the above factors will be regarded as changes in accounting estimate.

Deferred charges

Deferred charges are amortized using the straight-line method over the following periods: technology know-how, 5 years; technology license
fees, 5 years; software, 2 to 4 years; bond issuance costs, using the average method.

Goodwill and negative goodwill

Goodwill arising on consolidation represents the excess of the cost of acquisition over the Companys interest in the
fair value of the identifiable assets and liabilities of an investee company at the date of acquisition. Goodwill is recognized as an asset and carried at cost less accumulated impairment.

Goodwill arising on the acquisition of an associate or a jointly controlled entity is included within the carrying amount of the associate
or jointly controlled entity. Goodwill arising on the acquisition of subsidiaries is presented separately in the balance sheet.

Negative goodwill arising on consolidation represents the excess of the Companys interest in the fair value of the identifiable
assets and liabilities of an investee company over the cost of acquisition at the date of acquisition. Negative goodwill is allocated to the related assets according to the method applied to identify net assets at the process of acquisition.

Goodwill is tested for impairment on an annual basis regardless of whether there is any indication of impairment. Recognized
impairment losses of goodwill cannot be reversed.

Asset impairment

The Company reviews its long-lived assets, including properties, assets leased to others and deferred charges, to look for any indication
that an asset may be impaired as of the balance sheet date. An impairment loss is recognized whenever the recoverable amount of the asset of the cash-generating unit is below the carrying amount of an asset. If there is an indicator that an asset
may be impaired, then the Company calculates the recoverable amount of the asset or the cash-generating unit. Recoverability is determined by comparing the carrying value of the asset (or asset group) on the date it is tested for recoverability to
the sum of the undiscounted cash flows expected to result from its use and eventual disposition.

After the recognition of an
impairment loss, the depreciation (amortization) charged on the assets is adjusted in future periods by the revised carrying values of the assets (net of accumulated impairment), less their salvage value, on a systematic basis over their remaining
useful lives.

If an asset impairment loss (excluding goodwill) is reversed, the increase in the carrying value resulting from
the reversal is credited to current income or debited to accumulated impairment to increase the carrying value of the asset to its recoverable amount. However, loss reversal is limited to the carrying value (net of depreciation or amortization) of
the asset as if the impairment had not been recognized.

Revenue recognition

Revenue from testing and assembly services is generally recognized upon shipment of tested and assembled semiconductors to locations
designated by customers, including the Companys internal warehouse for customers using the Companys warehousing services. Revenue from product sales is recognized when title of products and risks of ownership are transferred to
customers, generally upon shipment of the products. Other criteria that the Company uses to determine when to recognize revenue are: (1) existence of persuasive evidence of the services provided, (2) customers fixed commitment to
purchase the products, (3) the selling price is fixed or determinable and (4) collectibility is reasonably assured.

The Company does not take ownership of: (1) bare semiconductor wafers received from customers that it assembles into finished
semiconductors, and (2) assembled semiconductors received from the customers that it tests. The title and risk of loss remains with the customer for those bare semiconductors and/or assembled semiconductors. Accordingly, the customer-supplied
semiconductor materials are not included in the consolidated financial statements.

These policies are consistent with
provisions in the Staff Accounting Bulletin No. 101, as revised by No. 104, issued by the United States Securities and Exchange Commission, or U.S. SEC which is now codified as Financial Accounting Statement Board Accounting Standard
Codification (FASB ASC) 605.

The Company does not provide warranties to customers except in cases of defects in the assembly
services provided and deficiencies in testing services provided. An appropriate sales allowance is recognized in the period during which the sale is recognized, and is estimated based on historical experience.

Government grant

A government grant is recognized at its fair value and credited to the income statement. Where the grant relates to an asset, the fair
value is credited to a deferred income account and is recognized as income over the periods necessary to match the related amortization of the asset, on a systematic basis.

Research and development costs

Research and development costs consist of expenditure incurred during the course of planned research and investigation aimed at discovery
of new knowledge which will be useful for developing new products or production processes, or significantly enhancing existing products or production processes, and the implementation of such through design and testing of product alternatives or
construction of prototypes. All expenses incurred in connection with the Companys research and development activities are charged to current income.

Pension and retirement costs

Defined benefit pension costs are recorded based on actuarial calculations. Provisions for pension costs are accrued based on actuarially
determined amounts which include service cost, interest, amortization of unrecognized net transition obligation and expected return on pension assets. Unrecognized net transition obligation is amortized over 15 years.

Retirement benefit contributions are made to a pension scheme and/or retirement funds, the assets of which are managed by independent
investment firms and/or government agencies. Contributions are made based on a percentage of the employees salaries and bonus, if applicable, and are charged to the income statement as incurred.

Income tax

The Company has adopted the inter-period income tax allocation method. Deferred income tax assets are recognized for the tax effects of
deductible temporary differences, unused tax credits, and operating loss carryforwards and those of taxable temporary differences are recognized as deferred income tax liabilities. A valuation allowance is provided for deferred tax assets that are
not certain to be realized. A deferred tax asset or liability is classified as current or non-current based on the classification of the related asset or liability. However, if a deferred asset or liability cannot be related to an asset or liability
in the financial statements, then it is classified as current or non-current based on the expected reversal dates of the temporary difference.

Any tax credit arising from the purchase of machinery, equipment and technology, research and development expenditures, personnel
training, or investments in important technology-based enterprise is recognized as incurred.

Adjustments of prior years
tax liabilities are added to or deducted from the current years tax provision.

Income taxes (10%) on unappropriated
earnings generated by ChipMOS Taiwan and ThaiLin are recorded as an expense in the year when the stockholders have effectively resolved that earnings shall be retained.

Alternative Minimum Tax (AMT) has been effective in the ROC since January 1, 2006. The calculation base for income tax payment should
be either the taxable income calculated by the AMT plus tax exemptions granted under other laws, taxed at the rate of 10% as set by the Executive Yuan of the ROC, or that calculated in accordance with the AMT, whichever is higher. The Company
includes the effect of the AMT for ChipMOS Taiwan and ThaiLin in the current income tax provision.

Advertising costs

Advertising costs included in sales and marketing expenses are expensed when incurred.

Foreign-currency transactions

Foreign-currency transactions, except for derivative financial instruments, are recorded in New Taiwan dollars at the rates of exchange in
effect when the transactions occur. Gains or losses resulting from the application of different foreign exchange rates when cash in foreign currency is converted into New Taiwan dollars, or when foreign-currency receivables or payables are settled,
are credited or charged to income in the year of conversion or settlement. On the balance sheet dates, the balances of foreign-currency assets and liabilities are restated at the prevailing exchange rates and the resulting differences are charged to
current income except those foreign currencies- denominated investments in shares of stock where such differences are accounted for as translation adjustments under equity. ROC SFAS No. 14, Accounting for Foreign-Currency
Transactions, applies to foreign operations, with the local currency of each foreign subsidiary as its functional currency. The financial statements of foreign subsidiaries are translated into New Taiwan dollars at the following exchange
rates: assets and liabilities - current rate; equity - historical rates; income and expenses - weighted average rate during the year. The resulting translation adjustment is recorded as a separate component of equity.

Earnings per share

Earnings per share is calculated by dividing net income by the weighted average number of shares outstanding in each period, adjusted
retroactively for stock dividends and stock bonuses issued subsequently. Diluted earnings per share reflects the potential dilution of securities by including other potential common stock equivalents, including stock options and warrants, and
convertible securities in the weighted average number of common shares outstanding for the year, if dilutive.

The following
table reconciles the denominator to calculate basic and diluted earnings (loss) per share:

Stock-based compensation

Effective January 1, 2008, the Company adopted SFAS No. 39 Share-based Payment. Prior to adoption of SFAS
No. 39, employee stock-based compensation has been accounted for under the intrinsic value based method. After the adoption of SFAS No. 39, employee stock-based compensation has been measured at the fair value of the options at grant date
using an option valuation model. The total stock-based compensation expense resulting from stock options is included in the consolidated statement of operations.

Share appreciation rights have been accounted for using the fair value method. Cash-settled stock appreciation rights have been recognized
as a liability.

Bonuses to employees, directors and supervisors

Effective January 1, 2008, the Company adopted Interpretation No. 96-052 issued by the Accounting Research and Development
Foundation (No. 96-052). Prior to adoption of No. 96-052, bonuses to employees, directors and supervisors were recorded as an appropriation of retained earnings when they are paid out. After the adoption of No. 96-052, bonuses to
employees, directors and supervisors were accrued and recorded in the consolidated statements of operations according to the Companys Articles of Incorporation.

Convertible notes

Convertible notes issued before January 1, 2006 were accounted for in accordance with SFAS No. 21 Accounting for
Convertible Bonds and thus, the related interest premium payable and amortization of discount or premium should be recognized.

Convertible notes issued after January 1, 2006 are split into liability and equity components. If a convertible debt instrument has
an embedded call or put option feature, the assessment of whether the call or put option is closely related to the host debt contract is made in accordance with SFAS No. 34 Financial Instruments: Recognition and Measurement. If the
derivatives embedded in the convertible notes are not closely related to the host debt contract, the put and call option features are carried at fair value with gains and losses in earnings.

The excess of the stated redemption price over the par value is accrued as compensation interest payable over the redemption period, using
the effective interest method.

When holders of convertible notes exercise their conversion right, the book value of the note
is credited to common stock at an amount equal to the par value of the common stock and the excess is credited to capital surplus. No gain or loss is recognized upon conversion of notes.

Treasury stock

The Companys stock held by its subsidiaries is treated as treasury stock. Treasury stock is stated at cost and shown as a deduction
in equity. When the Company retires treasury stock, the treasury stock account is reduced and the common stock as well as the capital surplus  additional paid-in capital are reversed on a pro rata basis. When the book value of the treasury
stock exceeds the sum of the par value and additional paid-in capital, the difference is charged to capital surplus  treasury stock transactions and to retained earnings for any remaining amount.

The noteholders of CN due 2011 have an option to cause ChipMOS Bermuda to repurchase for
cash all or a portion of the notes on September 29, 2008 at a repurchase price equal to 100% of the principal amount of the notes plus any accrued and unpaid interest to, but excluding, the date of repurchase (put option). On September 29,

occurrence of certain fundamental changes.

At any time on or after September 29, 2008, the Company may also at its option
redeem the notes for cash at a price equal to 100% of the principal amount of the notes plus accrued and unpaid interest, (a) in whole or in part, if the market price of the Companys common shares has been at least 130% of the conversion
price for at least 20 trading days during any 30 consecutive trading day period, or (b) in whole only, if at least 90% of the initial aggregate principal amount of the notes have been converted, repurchased or redeemed (call option).

Convertible notes due 2014 (CN due 2014)

On October 21, 2009, ChipMOS Bermuda completed an exchange transaction with a noteholder of CN due 2009 in an aggregate principal
amount of US$45,000 thousand for US$15,300 thousand (NT$488,835 thousand) in cash and US$15,750 thousand (NT$503,213 thousand) in new convertible notes of ChipMOS Bermuda due October 21, 2014. The CN due 2014 bear interest at 10% per annum
(10%CN due 2014).

In connection with the exchange transaction, the Company recorded a gain of NT$412,337 thousand. The gain
was recorded in non-operating income in the statement of operations.

The noteholder may convert any
outstanding notes into common shares of ChipMOS Bermuda, initially at the conversion price of US$1.50 per share, at any time during the period from the
41stday after the closing date to the close of business
on the tenth business day prior to the stated maturity date, subject to prior repurchase or redemption (Conversion) The conversion price will be subject to certain adjustment. In addition to the common shares issuable upon conversion, an amount
equal to the sum of any make-whole amount and any accrued and unpaid interest relating to the portion of the notes being converted is paid to the converting holder. Make-whole amount is the amount of interest that would have accrued with respect to
applicable conversion date, change of control repurchase date or redemption date, as the case may be, until the stated maturity, discounted to present value using the published yield on treasury notes of the U.S. Federal Government having a
comparable remaining tenor on the determination date plus 50 basis points; provided, however, the additional 50 basis points shall not be added if the applicable treasury note rate is greater than two percent (2%); in each case, the make-whole
amount shall be calculated by the Company. At any time after the issuance date, if (i) the closing sale price of the common shares on an eligible market exceeds two hundred percent (200%) of the conversion price then in effect for a period
of 20 consecutive trading days ending on the fifth trading day immediately preceding the company conversion notice date, (ii) the average daily trading volume of the common shares trading on an eligible market over such company conversion
measuring period equals or exceeds one percent (1%) of the then outstanding common shares and (iii) no equity conditions failure has occurred and is continuing, the Company shall have the right to convert some or all of the outstanding
principal amount of the Convertible Instruments as designated in a company conversion notice on the company conversion date. (Company conversion) At any time prior to the maturity date, the Company may redeem all or part of the outstanding amount in
cash. On the applicable redemption date, the Company shall redeem the outstanding principal amount specified in the redemption notice by paying in cash to the trustee as of the date of the redemption notice an amount equal to (a) the Principal
amount being redeemed plus (b) the sum of any make-whole amount and any accrued and unpaid interest (to but excluding the redemption date), if any, in each case relating to the outstanding portion of the CN due 2014 being redeemed. If the
Company redeems the CN due 2014 of a holder, the holder may nevertheless exercise its right to convert its CN due 2014 until the close of business on the day that is five business days immediately preceding the redemption date. (Redemption)

Interest on the CN due 2014 is payable at the Companys option on each interest payment date (1) in whole in cash,
(2) in whole in common shares or (3) in a combination of cash and common shares; provided, however, that in the case of the payment of common shares, in whole or in part, there shall not have been an equity conditions failure.

On December 29, 2009, ChipMOS Bermuda issued US$5,120 thousand (NT$164,710 thousand) CN due 2014 which bear interest at 8% per
annum (8%CN due 2014). The terms of 8%CN due 2014 are the same as 10%CN due 2014 except the conversion price and coupon rate. The conversion price of 8%CN due 2014 is US$1.25 per share and the coupon rate is 8%.

In accordance with ROC SFAS No. 34, the notes are recorded as liabilities using the effective interest method. The Company bifurcated

Unused credit lines of long-term bank loans as of December 31, 2009 totaled approximately NT$527,957
thousand.

Under syndicated bank loans facility agreements, ChipMOS Bermuda, ChipMOS Taiwan and ThaiLin are required to
maintain certain financial ratios. ThaiLin was waived from compliance of the times interest earned ratio requirement for 2009, and ChipMOS Taiwan was waived from compliance of the financial ratio requirements for 2008 and 2009. Pursuant to a bank
creditors meetings and the approval notice from Standard Chartered Bank on February 9, 2010, ChipMOS Bermuda, as borrower, and ChipMOS Taiwan, as guarantor were waived from compliance of the financial ratio requirements as of December 31,
2008 and December 31, 2009.

As of December 31, 2009, certain land and buildings and machinery were mortgaged as
collateral for the long-term loans. (Note 21).

On January 14, 2009 a meeting was arranged by ChipMOS Taiwan with all the
banks that have loans due between 2009 to 2013 for an extension of repayments and amendments on other terms and conditions on these loans (amendments). A bank creditors meeting hosted by Bank of Taiwan, the largest bank creditor,
was held on February 13, 2009 to discuss ChipMOS Taiwans request for an extension of loan repayment and amendments. At the meeting, it was resolved that the extension of loan repayment and amendments be approved and applicable to all bank
creditors with loans due in 2009 to 2013 once the bank creditors with loans due in 2009 to 2013 whose loans aggregated over 50% of the total bank loans due in 2009 to 2013 agreed. On April 6, 2009, Bank of Taiwan issued a letter to ChipMOS
Taiwan informing ChipMOS Taiwan that the bank creditors whose loan amounts aggregated over 50% of the total bank loans due in 2009 to 2013 formally agreed to the extension of loan repayment and amendments.

In April 2009, ChipMOS Bermuda applied to Standard Chartered Bank for the waiver of financial covenants of borrower and guarantor. In
February 2010, Standard Chartered Bank issued a notice to ChipMOS Bermuda informing ChipMOS Bermuda that majority lenders approval had been obtained to the waiver request.

Future minimum principal payments under the long-term loans as of December 31, 2009 are as follows:

ChipMOS Taiwan originally leased some equipment under operating leases. As part of the plan to remediate the
financial difficulty, ChipMOS Taiwan negotiated with the lessors and converted the leases of certain equipment into capital leases in November 2009. The capital leases mature in 2012-2013 and have buy-out options but they cannot be renewed,
terminated or refunded. The leased equipment and the corresponding capital leases payable are recorded at the lower of the fair value of the leased equipment and the present value of the minimum lease payments of such assets. The capital leases are
repayable in quarterly instalments and carry interest at floating rates of 3.9567% - 3.9609% as of December 31, 2009.

As
of December 31, 2009, the cost and accumulated depreciation of the leased equipment amounted to NT$2,363,168 thousand and NT$52,166 thousand, respectively. The depreciation charge for the year amounted to NT$52,166 thousand.

Future minimum lease payments under the capital leases as of December 31, 2009 are as follows:

|     |  |                |  |       

Under the capital leases, ChipMOS Taiwan is required
to maintain certain financial ratios, starting from 2010.

ChipMOS Taiwan obtained permission from the syndicated loan
borrowers (see Note 15 above) and pledged certain land and buildings and equipment to the above lessors. (Note 21) ChipMOS Taiwan also placed 104,695 thousand shares of ThaiLin under the custody of Taiwan Bank.



|17. | PENSION PLAN
|--- | ------------

ChipMOS Taiwan and
ThaiLin have established defined benefit pension plans for all of their regular employees, which provide benefits based on the length of service and the average monthly salary for the six-month period immediately before retirement.

ChipMOS Taiwan and ThaiLin make monthly contributions, equal to 2% of salaries and wages, to a pension fund that is administered by a
pension fund monitoring committee and deposited in the Central Trust of China in the Republic of China.

Taiwan has a new
pension scheme law effective July 1, 2005. The new pension scheme is a defined contribution scheme. All new employees who join or joined ChipMOS Taiwan and ThaiLin after July 1, 2005 must participate in the new scheme. Existing employees
can choose to stay with the old scheme or to join the new scheme. Under the new scheme, ChipMOS Taiwan and ThaiLin are required to contribute 6% of the employees salary into the employees own pension fund accounts managed by the
government.

The employees of ChipMOS Shanghai are required to participate in a central pension scheme operated by the local
municipal government. Contributions are made based on a percentage of the employees salaries and bonuses, if applicable, and are charged to the income statement as incurred.

Under
ROC Company Law, capital surplus can only be used to offset deficits, except that capital surplus generated from (1) donations (donated capital) or (2) the excess of the issue price over the par value of capital stock (including stocks
issued for new capital and mergers, and the purchase of treasury stock) can be transferred to capital as stock dividends when no deficit remains and shareholders approve such distribution.

ChipMOS Taiwans Articles of Incorporation provide that the following may be appropriated from the accumulated net income, after
deducting any previously accumulated deficit and 10% legal reserve, subject to shareholders approval: (a) 10% as bonuses to employees, (b) not more than 0.5% as remuneration to directors and supervisors, (c) a special reserve,
if deemed necessary, and (d) dividends to shareholders.

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



ThaiLins Articles of Incorporation provide that the following may be appropriated
from the accumulated net income, after deducting any previously accumulated deficit and 10% legal reserve, subject to shareholders approval: (a) not more than 0.5% as remuneration to directors and supervisors, (b) not less than 10%
as bonuses to employees, and (c) dividends to shareholders but not less than 50% should be distributed as cash dividends to shareholders.

These appropriations and the disposition of the remaining net income shall be resolved by the shareholders in the following year and given
effect in the financial statements of that year.

The aforementioned appropriation for legal reserve shall be made until the
reserve equals the aggregate par value of ChipMOS Taiwans and ThaiLins outstanding capital stock. The reserve can only be used to offset a deficit, or when its balance has reached 50% of the aggregate par value of the outstanding capital
stock of ChipMOS Taiwan and ThaiLin, and up to 50% thereof can be distributed as stock dividends.

Since the Company is an exempted company incorporated in Bermuda, a tax-free country, tax on pretax income is
calculated at the Bermuda statutory rate of 0% for each year.

ChipMOS Taiwan, under Science Park Regulations, is entitled to
an exemption from ROC income taxes for a period of four years on income attributable to the expansion of its production capacity as a result of purchases of new equipment funded by capital increases. Such tax exemption expired on December 31,
2008.

In accordance with the relevant tax rules and regulations in the PRC, ChipMOS Shanghai enjoys income tax exemptions for
the first two profitable years and 50% reductions for the following three years. Tax losses can only be carried forward for five years. ChipMOS Shanghai is subject to PRC income tax at 25%.

The deferred tax assets relate to investment tax
credits on research and development expenditure and purchases of machinery and equipment which will expire from 2010 to 2013. Under ROC tax regulations, tax credits can be utilized to reduce current income tax obligations only to the extent of 50%
of such income tax obligations except in the year when such tax credits will expire, in which case, the entire amount of expiring tax credits may be utilized to reduce the current income tax obligation. The foregoing limitation on the utilization of
tax credits, the expiry dates of the tax credits, the level of tax credits expected to be generated from future operations and the level of non-taxable income attributable to the four-year income tax holiday on capacity expansion led management to
conclude that it is unlikely that these investment tax credits will be fully realized. Losses carried forward can be used to deduct current income tax obligations up to the extent of taxable income and will expire after ten years if not fully
utilized by the Company. Accordingly, a valuation allowance on deferred tax assets is recognized as of December 31, 2008 and 2009.

The tax losses of ChipMOS Shanghai will expire after five years.

In the period from July to December 2003, MVI transferred its DRAM business to ProMOS.
As a result, 29%, 18% and 5% of the Companys 2007, 2008 and 2009 sales were made to ProMOS. The price was agreed upon quarterly, based on the then fair market price. The collection term for ProMOS was 75 days after month end. On
November 13, 2008, ChipMOS Taiwan and ProMOS revised the subcontracting contract by requiring ProMOS to provide wafers with a value of 80% of the subcontracting fee as collateral. Effective March 2009, the Company started to request prepayments
from ProMOS while other related parties have normal collection terms of 60 days after month end. The selling price is the same as for other customers.

The payment terms for purchases from related parties are the same as those from other suppliers.

In 2007, ChipMOS Taiwan sold tooling to ProMOS at NT$6,528 thousand.

In 2008, ProMOS used its machinery of NT$407,460 thousand, and bonds of NT$250,000 thousand and NT$400,000 thousand, to settle the payable
to ChipMOS Taiwan.

The other receivables from ProMOS of NT$30,000 thousand carried an interest of 3.51% per annum and was
secured by 4,061 thousand shares of ChipMOS Bermuda. In 2009, ProMOS used 4,061 thousand shares of ChipMOS Bermuda to settle the other receivables of NT$30,000 thousand and accounts receivable of NT$24,851 thousand.

On December 29, 2009, a director of the Company purchased NT$31,990 thousand (US$1,000 thousand) 8%CN due 2014 (Note 14).

| | g. | On April 1, 1999, Motorola, Inc. (Motorola) and ChipMOS Taiwan entered into an immunity agreement (the Agreement), that each party
covenanted not to sue each other for the use of certain Ball Grid Array (BGA) patents pursuant to the Agreement. In December 2004, Motorola spun off its semiconductor division and thereby formed Freescale Semiconductor, Inc.
(Freescale). Subsequently, Freescale assumed Motorolas rights and obligations under the Agreement. On October 16, 2006, Freescale unilaterally terminated the Agreement, alleging ChipMOS Taiwan breach of the Agreement. Under
the Agreement, ChipMOS Taiwan agreed to pay running royalties for its manufacturing of certain BGA packages covered by Motorola (now Freescale) patents pursuant to the Agreement. As such, ChipMOS Taiwan argued Freescales unilateral termination
of the Agreement has no legal effect. ChipMOS Taiwan has continued to accrue royalty payments for products it believes are covered by the Agreement. The payments previously returned by Freescale and accrued by ChipMOS Taiwan have been deposited in a
separate escrow account. On July 13, 2009, Freescale alleged that ChipMOS Taiwan breached the Agreement by failing to pay royalties on certain BGA packages assembled by ChipMOS Taiwan. Freescale claims that such packages are covered by one or
more Freescale patents identified in the Agreement while ChipMOS Taiwan contends that such packages are not covered by any of Freescales patents in the Agreement. ChipMOS Taiwan filed an answer to deny all allegations and also filed
counterclaims against Freescale alleging Freescale for engaging in patent misuse by seeking to obtain royalties on certain of ChipMOS Taiwans BGA products that were not covered by any Freescale patent included under the Agreement, and for
declaratory judgement of patent non-infringement and invalidity. In response, on December 11, 2009, Freescale filed a motion to dismiss the declaratory judgment counterclaims filed by ChipMOS Taiwan and to stay all other patent related claims
and issues until its breach of contract claims could be decided. That motion and the initial case management conference were held on March 5, 2010 and the motions were deemed submitted. A further case management conference is scheduled for
June 11, 2010. No trial date has been scheduled. The Companys counsel has not formed any opinion as to the outcome of the case.

| | h. | On April 20, 1999, ChipMOS Taiwan entered into a semiconductor packaging technology license agreement with Tessera Technologies, Inc. (Tessera). In February 2006,
ChipMOS Taiwan and ChipMOS USA received notice of a patent infringement lawsuit brought by Tessera, alleging infringement of several Tessera patents and breach of an existing license agreement with ChipMOS Taiwan. The fact discovery has been stayed
in accordance with a Northern District of California Court order issued on May 24, 2007. On April 21, 2008, Tessera requested that the International Trade Commission (ITC) investigate ChipMOS Bermuda, ChipMOS Taiwan and ChipMOS USA
(collectively referred to as the Companies) on the basis of alleged violations of Section 337 of the Tariff Act of 1930. In its request for investigation (ITC-649 Investigation), Tessera alleged that the Companies infringed certain
patents among which are three that were the subject of the stayed litigation in the Northern District of California. Tessera also requested that the ITC issue an exclusion order to enjoin the importation of accused products into the United States.
On September 30, 2008, Judge of Northern District of California Court (Judge) granted a motion to extend the hearing date from March 16 to March 24, 2009 and target date from August 28 to November 2, 2009. On
February 10, 2009, the Judge ordered the procedural schedule in the ITC-649 Investigation be stayed until the ITC issues its Final Determination in the ITC-605 Investigation. The target date of Initial Determination was also extended from
December 7, 2009 to February 8, 2010. On March 13, 2009, after the close of discovery, Tessera submitted a request to terminate the ITC-649 Investigation. On July 17, 2009, the Judge issued an order granting the request to
terminate the ITC-649 Investigation. No petitions for review were filed. The ITC had determined not to review the Initial Determination and issued an order to terminate the investigation on August 7, 2009. The stayed litigations may resume once
the ITC completes a companion investigation against other companies in the ITC-605 Investigation. The Companys counsel has not formed an opinion as to the outcome of the case.

| | a. | On December 28, 2009, Fulcrum Credit Partners LLC (Fulcrum) filed a complaint in Texas state court against ChipMOS Taiwan, ChipMOS USA, and Citigroup, alleging
(1) breach of contract, (2) promissory estoppel, (3) unjust enrichment, and (4) a claim for declaratory judgment, arising from Fulcrums alleged oral agreement to purchase ChipMOS Tawians claims against Spansion.
Though ChipMOS Taiwan was named in the complaint, ChipMOS Taiwan was not served. ChipMOS USA, however, was served. ChipMOS Taiwan was of the opinion that Fulcrum did not follow the offer procedures and therefore ChipMOS Taiwan has no obligation to
sell the claim to Fulcrum. On January 22, 2010, ChipMOS USA responded by removing the complaint to the US District Court for the Western District of Texas (Austin Division) (the Federal Court). On January 29, 2010, ChipMOS USA
file a motion to transfer venue to the Delaware Bankruptcy Court. Fulcrum filed its opposition to the transfer motion on February 8, 2010 and argument was held in the Western District of Texas (Austin Division) on February 11, 2010. On
February 17, 2010, Fulcrum filed an amended complaint in Federal Court alleging (1) breach of contract and (2) unjust enrichment claims against ChipMOS Taiwan and ChipMOS USA. Fulcrum has requested (1) all actual, consequential,
and exemplary damages to which Fulcrum is entitled; (2) all costs of the action and reasonable attorney fees that Fulcrum incurs in prosecuting that action; (3) pre- and post-judgment interest as permitted by law; (4) all other and
additional relief to which Fulcrum may show itself to be justly entitled, whether at low or in equity, On March 3, 2010, ChipMOS USA moved for dismissal from the Federal Court, asserting, inter alia, a complete defense in that the alleged
contract does not exist and, even if it did, ChipMOS USA was not a party, since ChipMOS Taiwan was not served with the amended complaint. Fulcrum filed its response to the motion to dismiss on March 15, 2010. No decision has been issued by the
court at this time. No provision for loss contingencies was made as Fulcrum has no valid grounds for its claim.

| | b. | On January 25, 2010, ChipMOS Taiwan entered into a definitive Transfer Of Claim Agreement (TOC Agreement) to sell to Citigroup Financial Products Inc.
(Citigroup) the general unsecured claim reflected in the proof of claim against Spansion filed by ChipMOS Taiwan in United States Bankruptcy Court. The claim that is the subject of the TOC Agreement includes accounts receivable for
testing and assembly services provided to Spansion in the amount of approximately NT$2,108,700 thousand to NT$2,236,500 thousand (US$66,000 thousand to US$70,000 thousand) (Undisputed Claim). The purchase price for the Undisputed Claim is
approximately NT$1,054,350 thousand (US$33,000 thousand). In February 2010], Citigroup paid the initial purchase price for the Undisputed Claim of NT$1,054,350 thousand (US$33,000 thousand) to the escrow agent and the escrow agent released the
initial purchase price to ChipMOS Taiwan. The TOC Agreement also includes the sale of breach of contract and liquidated damages rights against Spansion in the amount of approximately NT$7,476,300 thousand (US$234,000 thousand) (Damages Claim). The
purchase price for the Damages Claim is expected to be an amount that would be determined based on a Purchase Rate of 50.2% multiplied by the portion of the Damages Claim that is allowed by a final adjudication of the United States Bankruptcy Court.
The purchase price for the Damages Claim is payable to ChipMOS Taiwan to the extent that the Court allows this claim. If an objection to the claim transfer is filed in the Spansion bankruptcy proceeding prior to the end of the escrow period, the
agreement to sell the Damages Claim to Citigroup will terminate and the Damages Claim will not be transferred to Citigroup. In furtherance of the TOC Agreement, ChipMOS Taiwan has also entered into an agreement to subscribe for, purchase and
transfer to Citigroup rights offering shares to be issued by Spansion according to the Second Amended Joint Plan of Reorganization filed in United States Bankruptcy Court. This agreement provides that Citigroup will pay to Spansion the amount of the
rights offering shares purchase price.

|24. | DERIVATIVE FINANCIAL INSTRUMENTS
|--- | --------------------------------

ChipMOS Taiwan has entered into forward exchange contracts and foreign currency options for the years ended December 31, 2007, 2008
and 2009 to hedge its exchange rate risk on foreign-currency assets or liabilities and anticipated transactions. No derivative financial instrument was used during 2009. Information on the derivative transactions is as follows:



| | a. | Forward exchange contracts
| | -- | --------------------------

As of December 31, 2008 and 2009, there were no outstanding forward contracts.

Net exchange gains on forward exchange contracts were NT$123 thousand, nil and nil for the years ended December 31, 2007, 2008 and
2009, respectively.



| | b. | Financial risk information
| | -- | --------------------------



| | 1) | Credit risk. Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss.
The Company is exposed to credit risk from its operating activities (primarily for trade and other receivables). The Company performs ongoing credit evaluation of the debtors financial condition and maintains an allowance for doubtful
receivables based on historical collection, write-off experience and individual examination of available information regarding the customers. The banks with which the Company has entered into the above contracts are reputable and, therefore, the
Company is not expected to be exposed to significant credit risks.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2) | Market risk and hedge strategy. The Companys financial assets at fair value through profit and loss are stated at market value, which is affected by the stock
prices in the open stock market. The financial assets with no active market and held-to-maturity financial assets held by the Company are mainly fixed-interest-rate debt securities; therefore, the fluctuations in market interest rates will result in
changes in fair values of these debt securities. Subject to turmoil in the global financial market, the Company had evaluated its financial instruments and the Company believed the exposure to market risk as of December 31, 2009 was not
significant. The Company is exposed to market risks arising from changes in currency exchange rates due to U.S. dollar denominated accounts receivable, Yen denominated accounts payable and U.S. dollar denominated debt. In order to manage these
exposures, the Company sometimes enters into forward contracts and option contracts.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3) | Liquidity risk. Liquidity risk is the risk that the Company will encounter difficulty in raising funds to meet commitments associated with financial instruments.
Liquidity risk may result from an inability to sell a financial asset quickly at close to its fair value. Prudent liquidity risk management implies maintaining sufficient cash. The Company monitors and maintains a level of bank balances deemed
adequate to finance its operations. The Company employs projected cash flow analysis to manage liquidity risk by forecasting the amount of cash required and monitoring the working capital of the group to ensure that all liabilities due and known
funding requirements could be met. In addition, there are unused credit lines for contingency purposes.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4) | Cash flow interest rate risk. Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in
market interest rates. The Companys exposure to the risk of changes in market interest rates relates primarily to the Companys short and long term bank loans with floating interest rates. At 31 December 2009, it is estimated that a
general increase or decrease of 1% in interest rates, with all other variables held constant, would increase the Companys cash outflow by NT$142,867 thousand.

| | 6) | Refundable deposits and guarantee deposits  future values.
| | -- | -----------------------------------------------------------



| | 7) | Long-term liabilities  based on forecasted cash flows discounted at current interest rates of similar long-term liabilities. The fair value of convertible notes
in 2008 and 2009 is determined by option pricing models. Other long-term liabilities are their carrying values as they use floating interest rates.

|26. | SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES FOLLOWED BY THE COMPANY AND ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE UNITED STATES
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------

The accompanying financial statements have been prepared in accordance with accounting principles generally
accepted in the Republic of China (ROC GAAP), which differ in the following respects from accounting principles generally accepted in the United States of America (U.S. GAAP):



| | a. | Bonuses to employees, directors and supervisors
| | -- | -----------------------------------------------

According to ROC regulations and the Articles of Incorporation of ChipMOS Taiwan and ThaiLin, a portion of distributable earnings should
be appropriated as bonuses to employees and remuneration to directors and supervisors of ChipMOS Taiwan and ThaiLin. The remuneration to directors and supervisors is paid in cash, while bonuses to employees may be granted in cash or stock or both.
ChipMOS Bermudas portion of these appropriations is charged to earnings of ChipMOS Bermuda under ROC GAAP based on the amount to be paid as provided by ChipMOS Taiwan and ThaiLins Articles of Incorporation and is presented as a separate
line item below noncontrolling interest in the accompanying consolidated statements of operations. During 2009, ChipMOS Taiwan and ThaiLin did not pay any bonuses to directors, supervisors and employees. During 2008, NT$386,698 thousand and
NT$57,908 thousand, respectively were paid to directors, supervisors and employees as bonuses. Commencing from January 1, 2009, bonuses to employees, directors and supervisors were accrued according to the Articles of Incorporation. As ChipMOS
Taiwan and ThaiLin incurred losses for the year ended December 31, 2008 and 2009, no bonuses were accrued. There are no difference between ROC GAAP and U.S. GAAP effective January 1, 2008.



| | b. | Technologies transferred in payment of capital stock
| | -- | ----------------------------------------------------

Pursuant to a Joint Venture Agreement entered into between MVI and SPIL on July 28, 1997, MVI and SPIL contributed, as payment for
their subscription in the shares of stock of ChipMOS Taiwan, technologies relating to the testing and assembly of semiconductors at an agreed value of NT$750,000 thousand. Under ROC GAAP, such technology transfers in payment of capital stock are
recorded as an intangible asset, and amortized by systematic charges to income over the periods estimated to be benefited. As permitted under ROC GAAP, the Company uses a five-year amortization period. Under U.S. GAAP, the technology contribution
cannot be recognized due to the unavailability of a fair value for the technologies. Therefore, the carrying value of the technologies has been adjusted to zero under U.S. GAAP.



| | c. | Start-up costs
| | -- | --------------

ROC GAAP
requires start-up costs to be deferred and amortized in a systematic manner over its estimated useful beneficial life. Start-up costs include all costs incurred prior to production readiness. On the other hand, U.S. GAAP primarily requires that
start-up costs be expensed as incurred. Some of the expenses were recorded in manufacturing expenses and therefore also affect ending inventory balances under U.S. GAAP.



| | d. | Depreciation of property, plant and equipment and employee dormitory building
| | -- | -----------------------------------------------------------------------------

Under ROC GAAP, the estimated life of a building can be as long as 55 years based on the ROC Internal Revenue Code. For U.S. GAAP
purposes, building lives are estimated to be 25 years. Some of the depreciation expenses were recorded in manufacturing expenses and therefore also affect ending inventory balances under U.S. GAAP.



| | e. | Transfer of building and facilities from MVI
| | -- | --------------------------------------------

The Company purchased buildings and facilities from MVI in 1997. The costs of assets purchased from MVI were based on MVIs book
value of such building and facilities on a specified cut-off date plus an additional payment of NT$173,174 thousand representing compensation to MVI. This additional payment of NT$173,174 thousand was capitalized by the Company as allowed under ROC
GAAP. Under U.S. GAAP, assets acquired are recorded at amounts that do not exceed their fair values. Also, generally under U.S. GAAP, the transferee should record the assets transferred from related parties with significant influence at the
predecessors basis. Therefore, the transfer of assets from MVI was recorded at MVIs predecessor cost basis and NT$173,174 thousand was deducted from the capital surplus and building and facilities for the purposes of U.S. GAAP. Some of
the related depreciation expenses were recorded in manufacturing expenses and therefore also affect ending inventory balances under U.S. GAAP.



| | f. | Impairment of long-lived assets
| | -- | -------------------------------

Impairment assessments are made by the Company when events and circumstances exist that indicate the carrying value of these assets may
not be recoverable. In view of the sustained losses incurred by ChpiMOS Shanghai, the Company reviewed ChipMOS Shanghais property, plant and equipment and land use rights for potential impairment as at December 31, 2008 and 2009.

|26. | SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES FOLLOWED BY THE COMPANY AND ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE UNITED STATES (continued)
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



Under U.S. GAAP, impairment losses for assets to be held and used are recorded in
current period earnings and create a new cost basis for related assets going forward, and cannot be reversed subsequently. Under U.S. GAAP, in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived
Assets, which is now codified as FASB ASC 360, long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An
impairment loss shall be recognized only if the carrying amount of a long-lived asset (asset group) is not recoverable and exceeds its fair value. The carrying amount of a long-lived asset (asset group) is not recoverable if it exceeds the sum of
the undiscounted cash flows expected to result from the use and eventual disposition of the asset (asset group). That assessment shall be based on the carrying amount of the asset (asset group) at the date it is tested for recoverability, whether in
use or under development. An impairment loss shall be measured as the amount by which the carrying amount of a long-lived asset (asset group) exceeds its fair value. Fair value is determined by the Company using future cash flows discounted at
current rates. There are no differences in impairment losses recognized under ROC GAAP and U.S. GAAP in 2007, 2008 and 2009.



| | g. | Earnings per share (EPS)
| | -- | ------------------------

In
calculating the weighted average number of shares outstanding for EPS purposes under ROC GAAP, employee bonus shares have been treated as outstanding for all periods in a manner similar to a stock split or stock dividend. Under U.S. GAAP, employee
bonus shares have been considered separately from the stock dividend or split and have been treated as outstanding from the date of shareholder approval.



| | h. | Interest capitalization
| | -- | -----------------------

Under
ROC GAAP, interest on borrowings during construction conceptually should be capitalized in the assets that are constructed or produced for a companys own use. However, if equity capital is raised during a year, no capitalization interest is
recorded for the amount of property acquired up to the equity capital raised in that year. Under U.S. GAAP, SFAS No. 34 Capitalization of Interest Cost, interest is generally capitalized on assets until they are available and ready
for use.



| | i. | Inventories stated at lower of cost or market
| | -- | ---------------------------------------------

ROC GAAP allows assessment of carrying values of inventories on an aggregate basis. An allowance was made when the aggregate carrying
values of inventories were higher than market.

Under U.S. GAAP, the Companys assessed inventories at the lower of cost
or market on an item-by-item basis. This resulted in an additional write-off of NT$36,818 thousand which was charged to the consolidated statement of operations a component of cost of revenue in 2008.

Under ROC GAAP and effective January 1, 2009, the Company adopted the revised SFAS No. 10R. The Company is required to assess
inventories at the lower of cost or market on an item-by-item basis. Therefore, there are no difference between ROC GAAP and U.S. GAAP effective January 1, 2009. The adjustment in 2009 relates to reversal of the allowance made under U.S. GAAP
in 2008.



| | j. | Convertible notes
| | -- | -----------------

Under ROC
GAAP, there is no requirement to account for the fair value of a conversion feature embedded in CN due 2009 as it was issued before January 1, 2006. Under U.S. GAAP, the Company accounts for the fair value of the conversion feature of its
convertible notes in accordance with SFAS No. 133, Accounting For Derivative Instruments And Hedging Activities and related pronouncements, which is now codified as FASB ASC 815, which require the Company to bifurcate and separately
account for the conversion feature as embedded derivatives contained in the Companys convertible notes. The Company carried these embedded derivatives on its balance sheet at fair value and changes in fair values of these embedded derivatives
are reflected in the consolidated statement of operations. Commencing January 1, 2006, ROC GAAP requires the Company to bifurcate and separately account for put and call option features contained in the Companys convertible notes issued
after 2005. The Company issued convertible notes (CN due 2011) on September 29, 2006. The Company carried the put and call options of the CN due 2011 on the balance sheet at fair value with changes in fair values reflected in the consolidated
statement of operations. The other conversion features are recorded in equity. (See Note 27 i.)

Commencing from
January 1, 2006, under ROC GAAP, the issue costs of convertible notes are recorded as a reduction of the convertible notes. Under U.S. GAAP the issue costs are capitalized as deferred assets and amortized over the period of the convertible
notes.

There is no difference under ROC GAAP and U.S. GAAP in accounting for the CN due 2014 (See Note 14).

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



| | k. | Share-based payments
| | -- | --------------------

Under ROC
GAAP, the Company followed Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB No. 25), in accounting for its employee stock option plans prior to January 1, 2008. Under
APB No. 25, when the exercise price of the Companys stock options is less than the market price of the underlying shares on the date of grant, compensation expense is recognized. Under U.S. GAAP, commencing from January 1, 2006, the
Company applies SFAS No. 123(R), Share-Based Payment, Emerging Issues Task Force No. 96-18, Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or
Services, which is now codified as FASB ASC 718, with respect to options and warrants issued to non-employees. FASB ASC 718 requires the use of option valuation models to measure the fair value of the options and warrants at the measurement
date. The total stock-based compensation expense resulting from stock options was included in general and administrative expenses in the consolidated statements of operations. As explained in Note 2 above, there is no difference between ROC GAAP and
U.S. GAAP effective January 1, 2008 upon adoption of ROC SFAS No. 39 for options granted since January 1, 2008.



| | l. | Defined Benefit Pension Plans
| | -- | -----------------------------

Under U.S. GAAP, commencing from January 1, 2006, the Company applies SFAS No. 158, Employers Accounting for
Defined Benefit Pension and Other Postretirement Plans, which is now codified as FASB ASC 715. FASB ASC 715 requires an employer that sponsors one or more defined benefit pension plans or other postretirement plans to 1) recognize the
funded status of a plan, measured as the difference between plan assets at fair value and the benefit obligation, in the balance sheet; 2) recognize in equity as a component of accumulated other comprehensive loss, net of tax, the gains or
losses and prior service costs or credits that arise during the period but are not yet recognized as components of net periodic benefit cost; 3) measure defined benefit plan assets and obligations as of the date of the employers fiscal
year-end balance sheet; and 4) disclose in the notes to the financial statements additional information about the effects on net periodic benefit cost for the next fiscal year that arise from delayed recognition of the gains or losses, prior
service costs or credits, and transition asset or obligation. Under ROC GAAP, there is no such requirement for recognition.



| | m. | Income tax expense
| | -- | ------------------

Effective
January 1, 2007, the Company adopted Financial Interpretation No. 48, Accounting for Uncertainty in Income Taxesan interpretation of FASB Statement No. 109, which is now codified as FASB ASC 740. FASB ASC 740
prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This interpretation also provides guidance on derecognition of income tax assets and
liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions and income tax disclosures.

Uncertain tax positions have been classified as non-current income tax liabilities unless these are expected to be paid in one year. The
Companys policy for interest and penalties related to income tax exposure is to recognize interest and penalties as a component of the provision of income taxes in the consolidated statement of operations.

The Company is potentially subject to income tax audits in the ROC and internationally until the applicable statute of limitations expire.
Tax audits by their nature are often complex and can require several years to complete. The following is a summary of tax years, potentially subject to examination, in the significant tax and business jurisdictions in which the Company operates:



|                           |  |                                
|-------------------------- |  | -------------------------------
|Jurisdiction               |  | Tax Years Subject toExamination
|Republic of China          |  | 5 Years                        
|United States              |  | 3 Years                        
|Hong Kong                  |  | 6 Years                        
|Peoples Republic of China |  | Unlimited                      

As of
December 31, 2009, the allowance for current tax assets was decreased by NT$1,960 thousand (US$61 thousand) and the long-term tax payable was decreased by NT$18,268 thousand (US$572 thousand).

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



The Companys subsidiaries are currently under examination by the relevant tax
authorities for various tax years. The Company regularly assesses the potential outcome of these examinations in each of the taxing jurisdictions when determining the adequacy of the amount of unrecognized tax benefit recorded. While it is often
difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes it has appropriately accrued for uncertain tax benefits. However, audit outcomes and timing of audit settlements and
future events that would impact the previously recorded unrecognized tax benefits and the range of anticipated increases or decreases in unrecognized tax benefits are subject to significant uncertainty. It is possible that the ultimate outcome of
current or future examinations may exceed current unrecognized tax benefits in amounts that could be material, but cannot be estimated as of December 31, 2009. The effective tax rate and net income in any given future period could therefore be
materially impacted.

There are no such provisions under ROC GAAP.



| | n. | Investments with no active market
| | -- | ---------------------------------

Under U.S. GAAP, the NT$ 300,000 thousand bonds are classified as available-for-sale investments. Changes in fair value are recorded
in equity. Investment with no active market is not a category of investment under U.S. GAAP.



| | o. | Cash and cash equivalents
| | -- | -------------------------

Under
ROC GAAP, cash and cash equivalents include time deposits regardless of its maturity date. Under U.S. GAAP, cash equivalents are short-term, highly liquid investments that are readily convertible to cash with original maturities of three months or
less. Thus, time deposits with original maturities of more than three months are classified as cash equivalents under ROC GAAP but should be included in other current assets under U.S. GAAP.



| | p. | Classification of non-operating income/expenses
| | -- | -----------------------------------------------

Under ROC GAAP, gains on disposal of plant and equipment, land use rights, scrap material and tooling are recorded as non-operating
income; and impairment losses on property and equipment, other assets, and goodwill are recorded as non-operating expenses as these items represent revenue and expenses not arising from ordinary operating activities.

Under U.S. GAAP, gains on disposal of plant and equipment, land use rights, scrap material and tooling are recorded as other operating
income; and impairment losses on property and equipment, other assets, and goodwill are recorded as operating expenses.

In June 2009, the FASB issued FASB ASC 105, which establishes the FASB Accounting Standards Codification as the source of
authoritative accounting principles recognized by the FASB to be applied in the preparation of financial statements in conformity with generally accepted accounting principles. ASC No. 105 explicitly recognizes rules and interpretive releases
of the Securities and Exchange Commission (SEC) under federal securities laws as authoritative GAAP for SEC registrants. FASB ASC 105 is effective for financial statements issued for interim and annual periods ending after
September 15, 2009. The Codification is effective for the Company for the year ended December 31, 2009. Adoption of FASB ASC 105 did not have a material impact on the Companys consolidated financial statements.

In September 2006, the FASB issued guidance in FASB ASC 820 which defines fair value, establishes a framework for measuring fair
value and expands disclosure requirements about fair value measurements. The guidance was effective for the Companys financial assets and liabilities on January 1, 2008. Effective January 1, 2009, the Company adopted FASB ASC 820 for
the Companys non-financial assets and liabilities. The adoption did not have a material impact on the consolidated financial statements upon adoption. FASB ASC 820 establishes a fair value hierarchy that distinguishes between assumptions based
on market data (observable inputs) and the Companys assumptions (unobservable inputs). The hierarchy consists of three broad levels as follows:

Level 1Quoted market prices in active markets for identical assets or liabilities

Level 2Inputs other than level 1 that are either directly or indirectly observable

Level 3Unobservable inputs developed using the Companys estimates and assumptions, which reflect those that market
participants would use.

The following table sets forth the assets measured at fair value on a recurring basis, by input level,
as of December 31, 2009:



|                                                       |  |                |  |         |  |         |  |        
|------------------------------------------------------ |  | -------------- |  | ------- |  | ------- |  | -------
|                                                       |  | Level 1        |  | Level 2 |  | Level 3 |  | Total

|Financial assets at fair value through profit and loss |  | 119,027        |  |        |  |        |  | 119,027
|Available-for-sale investments                         |  |               |  |        |  | 300,000 |  | 300,000
|                                                       |  |                |  |         |  |         |  |        
|                                                       |  | 119,027        |  |        |  | 300,000 |  | 419,027
|                                                       |  |                |  |         |  |         |  |        

Financial assets at fair value through profit and loss
include investments in stocks and open-ended funds, which are measured using quoted price in active markets and are classified as Level 1.

Available-for-sale investments are comprised of bonds. The fair values are based on future cash flows discounted at current rates as the
bonds are trading in an inactive market.

In February 2007, the FASB issued guidance in FASB ASC 825 which allows entities to
choose, at specified election dates, to measure eligible financial assets and liabilities at fair value that are not otherwise required to be measured at fair value. If a company elects the fair value option for an eligible item, changes in that
items fair value in subsequent reporting periods must be recognized in earnings. FASB ASC 825 also establishes presentation and disclosure requirements designed to draw comparison between entities that elect different measurement attributes
for similar assets and liabilities. FASB ASC 825 is effective for the year ended December 31, 2009. The adoption has no impact on the consolidated financial statements.

In December 2007, the FASB issued guidance in FASB ASC 810 which requires that a noncontrolling interest in a subsidiary be reported
as equity and the amount of consolidated net income specifically attributable to the noncontrolling interest be identified in the consolidated financial statements. It also calls for consistency in the manner of reporting changes in the
parents ownership interest and requires fair value measurement of any noncontrolling equity investment retained in a deconsolidation. FASB ASC 810 is effective for the year ended December 31, 2009. The adoption has no impact on the
Companys consolidated financial condition, results of operations, and cash flows as noncontrolling interest was reported as equity prior to adoption of FASB ASC 810.

In December 2007, the FASB issued guidance in FASB ASC 805, extending the applicability to all transactions and other events in which
one entity obtains control over one or more other businesses. It broadens the fair value measurement and recognition of assets acquired, liabilities assumed, and interests transferred as a result of business combinations. The guidance expands on
required disclosures to improve the statement users abilities to evaluate the nature and financial effects of business combinations. FASB ASC 805 is effective for the year ended December 31, 2009. The adoption did not have any significant
impact on the Companys consolidated financial statements for the year ended December 31, 2009 but may have impact for any future acquisitions.

In March 2008, the FASB issued guidance in FASB ASC 815 which requires enhanced
disclosures about an entitys derivative and hedging activities, including (a) how and why an entity uses derivative instruments, (b) how derivative instruments and related hedged items are accounted for and (c) how derivative
instruments and related hedged items affect an entitys financial position, financial performance, and cash flows. FASB ASC 815 is effective for the year ended December 31, 2009. The adoption did not have any impact on the Companys
consolidated financial statements.

In April 2008, the FASB issued guidance in FASB ASC 350 which amends the factors that
should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset. FASB ASC 350 is intended to improve the consistency between the useful life of an intangible asset and the period
of expected cash flows used to measure the fair value of the asset under other applicable accounting literature. FASB ASC 350 is effective for the year ended December 31, 2009. The adoption had no material effect on the Companys
consolidated financial statements.

In May 2008, the FASB issued guidance in FASB ASC 470 and 815 which requires cash
settled convertible debt to be bifurcated into debt and equity components and accounted for separately at issuance. The value assigned to the debt component would be the estimated fair value, as of the issuance date, of a similar bond without the
conversion feature. The difference between the bond cash proceeds and this estimated fair value would be recorded as a debt discount and amortized to interest expense over the life of the bond. The equity component of the convertible debt securities
would be included in the paid-in-capital section of equity on the Companys consolidated balance sheets and the initial carrying values of these debt securities would be correspondingly reduced. Management does not expect that the application
of this standard will have any significant effect on the Companys consolidated financial statements.

In December 2008,
the FASB issued guidance in FASB ASC 715 requiring enhanced disclosures about the plan assets of defined benefit pension and other postretirement plans. The enhanced disclosures are intended to provide users of financial statements with a greater
understanding of: (1) how investment allocation decisions are made, including the factors that are pertinent to an understanding of investment policies and strategies; (2) the major categories of plan assets; (3) the inputs and
valuation techniques used to measure the fair value of plan assets; (4) the effect of fair value measurements using significant unobservable inputs (Level 3) on changes in plan assets for the period; and (5) significant concentrations of
risk within plan assets. The enhanced disclosures are effective for the financial statements for the year ended December 31, 2009. The enhanced disclosures are included in note 27 d.

In April 2009, the FASB issued three related staff positions to clarify the application of FASB ASC 820 to fair value measurements in the
current economic environment, modify the recognition of other-than-temporary impairments of debt securities, and require companies to disclose the fair value of financial instruments in interim periods. The final staff positions are effective for
interim and annual periods ending after March 15, 2009. The adoption of FASB ASC 820 had no material effect on the Companys consolidated financial statements.

In April 2009, the FASB issued guidance in FASB ASC 820 which clarifies when markets are illiquid or that market pricing may not actually
reflect the real value of an asset. If a market is determined to be inactive and market price is reflective of a distressed price then an alternative method of pricing can be used, such as a present value technique to estimate fair
value. FASB ASC 820 identifies factors to be considered when determining whether or not a market is inactive. FASB ASC 820 is effective for interim and annual periods ending after June 15, 2009. The adoption of FASB ASC
820 had no material effect on the Companys consolidated financial statements.

In May 2009, the FASB issued guidance
in FASB ASC 855 on subsequent events that establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but prior to the issuance of the financial statements. The guidance requires disclosure of the
date through which subsequent events were evaluated and the basis for that date. The guidance sets forth the following: (1) the period after the balance sheet date during which management of a reporting entity should evaluate events or
transactions that may occur for potential recognition or disclosure in the financial statements; (2) the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial
statements; and (3) the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. This guidance is effective for the year ended December 31, 2009. Effective February 24, 2010, the
Company adopted Accounting Standards Update (ASU) No. 2010-09 Subsequent Events (Topic 855): Amendment to Certain Recognition and Disclosure Requirements, which removes the requirement to disclose the date through which subsequent
events have been evaluated. Please refer to note 23 for disclosure of subsequent events.

In June 2009, the FASB issued FASB ASC 860 which eliminates the concept of a
qualifying special-purpose entity, creates more stringent conditions for reporting a transfer of a portion of a financial asset as a sale, clarifies other sale-accounting criteria, and changes the initial measurement of a transferors interest
in transferred financial assets. ASC No. 860 will be effective for transfers of financial assets in fiscal years beginning after November 15, 2009, and in interim periods within those fiscal years with earlier adoption prohibited. The
Company is currently evaluating the impact of the adoption of FASB ASC 860 on its consolidated financial statements.

In
June 2009, the FASB issued FASB ASC 810 which address the elimination of the concept of a qualifying special purpose entity. ASC No. 810 also replaces the quantitative-based risks and rewards calculation for determining which enterprise
has a controlling financial interest in a variable interest entity with an approach focused on identifying which enterprise has the power to direct the activities of a variable interest entity and the obligation to absorb losses of the entity or the
right to receive benefits from the entity. Additionally, FASB ASC 810 provides more timely and useful information about an enterprises involvement with a variable interest entity. FASB ASC 810 will be effective as of the beginning of each
reporting entitys first annual reporting period that begins after November 15, 2009, for interim periods within that first annual reporting period, and for interim and annual reporting periods thereafter. Earlier application is
prohibited. The Company is currently evaluating the impact of the adoption of FASB ASC 810 on its consolidated financial statements.

In August 2009, the FASB issued Accounting Standards Update No. 2009-02 (ASU 2009-03), SEC update  Amendments to
various topics containing SEC Staff Accounting Bulletins to update cross-references to Codification test. ASU 2009-03 did not have a material effect on the Companys consolidated financial position or results of operations.

In August 2009, the FASB issued Accounting Standard Update No.2009-05 (ASU 2009-05) which applies to all entities that measure
liabilities at fair value within scope of ASC No, 820. ASU 2009-05 provides clarification that in circumstances in which a quoted price in an active market for the identical liability is not available, a reporting entity is required to measure fair
value using one or more valuation techniques. The amendments in ASU 2009-05 also clarify that when estimating the fair value of a liability, a reporting entity is not required to include a separate input or adjustment to other inputs relating to the
existence of a restriction that prevents the transfer of the liability. It also clarifies that both a quoted price in an active market for the identical liability at the measurement date and the quoted price for the identical liability when traded
as an asset in an active market when no adjustments to the quoted price of the asset are required are Level 1 fair value measurements. The guidance provided in ASU 2009-05 is effective for the first reporting period beginning after issuance. The
Company is currently evaluating the impact of the adoption of ASU 2009-05 on its consolidated financial statements.

In
September 2009, the FASB issued Accounting Standards Update No. 2009-07 (ASU 2009-07), Accounting for Various Topics. ASU 2009-07 represents technical corrections to various topics containing SEC guidance based on external
comments received. The adoption of this guidance did not have a material effect on the Companys consolidated financial condition or results of operations.

In September 2009, the FASB issued Accounting Standards Update No. 2009-12 (ASU 2009-12), which provides amendments
to Subtopic 820-10, Fair Value Measurements and Disclosures  Overall, for the fair value measurement of investments in certain entities that calculate net asset value per share. This ASU also requires disclosures by major category of
investment about the attributes of investments within the scope of the amendments in this Update. The amendments in this Update are effective for interim and annual periods after December 15, 2009. The Company is currently evaluating the impact
of the adoption of ASU 2009-12 on its consolidated financial statements.

In December 2009, the FASB issued ASU
No. 2009-17. The amendments in this update are the result of FASB Statement No. 167 Amendments to FASB Interpretation No. 46 (R), which is now codified as FASB ASC 810-10-50-2A Consolidation  Overall 
DisclosureVariable Interest Entities. The adoption of FASB ASU No. 2009-17 did not have a material impact on the Companys financial position, results of operations and cash flows.

In January 2010, the FASB issued ASU No. 2010-02, in which it clarifies that the scope of the decrease in ownership provision of ASC
810-10 and related guidance applies to a subsidiary or group of assets that is a business or nonprofit activity, but does not apply to sales of in-substance real estate and conveyances of oil and gas mineral rights. The adoption of ASU
No. 2010-02 did not have a material impact on the Companys financial position, results of operations and cash flows.

The Company tests goodwill for impairment annually as
of December 31 and whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Recoverability of goodwill is measured at the reporting unit level by comparing the reporting units carrying amount,
including goodwill, to the fair value of the reporting unit, which is measured based upon, among other factors, market multiples for comparable companies as well as a discounted cash flow analysis. The goodwill is allocated to two reporting units:
ChipMOS Taiwan and ThaiLin. If the recorded value of the assets, including goodwill, and liabilities (net book value) of the reporting unit exceeds its fair value, an impairment loss may be required to be recognized.

Pursuant to the guidance in SFAS 142, Goodwill and Other Intangible Assets (SFAS 142), the measurement of
impairment of goodwill consists of two steps. In the first step, the fair value of the reporting unit is compared to its carrying value. In connection with the preparation of the financial statements for the year ended December 31, 2008,
management made a determination of the fair value of the two reporting units. Fair value is determined using a combination of an income approach, which estimates fair value based upon future revenue, expenses and cash flows discounted to their
present value, and a market approach, which estimates fair value using market multiples to various financial measures compared to a set of comparable public companies in listed on the Taiwan Stock Exchange. Management concluded the estimated fair
values of the reporting units were less than their net book values. Accordingly the guidance in SFAS 142 requires a second step to determine the implied fair value of the Companys goodwill, and to compare it to the carrying value of the
Companys goodwill. This second step includes valuing all of the tangible and intangible assets and liabilities of the reporting unit as if it had been acquired in a business combination, including valuing all of its intangible assets even if
they were not currently recorded to determine the implied fair value of goodwill. Based on managements analysis incorporating the declining market capitalization in 2008, as well as the significant market deterioration and economic
uncertainties impacting expected future demand, management concluded that the entire goodwill balance of NT$969,188 thousand was impaired. As a result, the Company recognized a non-cash impairment charge of approximately NT$969,188 thousand for the
year ended December 31, 2008 to write-off the entire carrying value of its goodwill.

Employee stock-based compensation has been accounted for under FASB ASC 715.

The Company has in place a Share Option Plan (2001 Plan). Under the terms of the plan, the exercise price set on the grant of share
options may not be less than the par value of a Company Share on the date of grant of such option. In August 2006, the Company adopted a second Share Option Plan (2006 Plan). The number of shares that may be issued under the two plans is 16,000,000
shares and may consist in whole or part of authorized but unissued shares of the Company which are not reserved for any other purpose. No consideration is payable for the grant of an option.

Under the plans, options may be granted to all directors, officers, employees and consultants of the Company and its affiliates. Options
are exercisable for a maximum of ten years from the date on which such option is granted and five years from the date on which such option is granted if the holder of the option owns more than 10% of the combined voting power of the Company at the
time the option is granted.

In September 2006, the Company adopted a share appreciation rights plan. The share
appreciation rights plan provides that the directors, officers and employees of the Company and its affiliates may be granted cash-settled share appreciation rights.

The fair value for options granted has been estimated at the date of grant using the Black-Scholes Option Pricing Model with the following
weighted average assumptions:

The aggregate intrinsic value in the table above represents the total intrinsic value (i.e., the
difference between the Companys closing stock price of US$0.71 on December 31, 2009 (December 31, 2008: US$0.25) and the exercise price, times the number of options) that would have been received by the option holders had all option
holders exercised their options on December 31, 2009. The total intrinsic value of options exercised during the year ended December 31, 2009 was nil (2008: nil). The total fair value of options vested and forfeited during the year ended
December 31, 2009 was NT$94,157 thousand (US$2,947 thousand) (2008: NT$121,802 thousand). The number of options vested during the year ended December 31, 2009 was nil (2008: 127,850). The weighted average remaining contractual term of the
outstanding options at December 31, 2009 was 4 (2008: 4.5) years.

As of December 31, 2009, NT$12,810 thousand
(US$401 thousand) (2008: NT$40,878 thousand) of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted average period of 2 years.

The Companys determination of fair value of employee share options on the date of grant
using the Black Scholes Option Pricing Model is affected by the Companys stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to the Companys
expected stock price volatility over the term of the awards. Option pricing models were developed for use in estimating the value of traded options that have no vesting or hedging restrictions and are fully transferable. Because the Companys
employee stock options have certain characteristics that are significantly different from traded options, and because changes in the subjective assumptions can materially affect the estimated value, in managements opinion, the existing
valuation models may not provide an accurate measure of the fair value of the Companys employee stock options. Although the fair value of employee stock options is determined in accordance with FASB ASC 715 using an option pricing model, that
value may not be indicative of the fair value observed in a willing buyer/willing seller market transaction.



| | i. | Convertible notes
| | -- | -----------------

The Company
accounts for the conversion option in the convertible notes as derivative liabilities in accordance with FASB ASC 815. The discount attributable to the issuance date aggregate fair value of the conversion option, totaling NT$1,380,211 thousand
(US$43,199 thousand), is being amortized using the effective interest method over the term of the convertible notes.

The
change in fair value on revaluation of the embedded derivative liabilities represents the difference between the fair value of the embedded derivative liabilities at their original issue date and their fair value on December 31, 2009 using
option pricing models. As of December 31, 2009, the fair value of the embedded derivative liabilities amounted to NT$129,967 thousand (US$4,068 thousand). The effect of the fair market value adjustment of NT$50,740 thousand (US$1,588 thousand)
was recorded in the consolidated statement of operations.

The following assumptions were applied to the convertible notes
using the option pricing model:
