Transaction Premium Analysis

Lehman Brothers reviewed the premium paid in acquisitions of minority buy-outs of public targets announced since 2002 with equity values greater than US $100 million, where 100% of the consideration was paid in cash. Lehman Brothers calculated the premium per share paid by the acquiror compared to the average share price of the target company for a period of one day, one week, one month and three months prior to the announcement of the transaction. This analysis produced a median premi um of 22.4% for the one-month average share price. Lehman Brothers then applied a range of premium of 10% to 30 % to the average one-month closing price of US$11.77 of ASE Test Nasdaq Shares as of August 31, 2007, in order to derive an implied share price reference range for ASE Test. Lehman Brothers noted that the proposed per share scheme consideration of US$14.78 represented a premium of 25.6% to the one-month average closing price for the ASE Test Nasdaq Shares. The NT$ “ pass through ” scheme consideration for each ASE Test TDS represented a premium of 14.4% to the one-month average closing price of ASE Test TDSs. In connection with the ASE Test TDSs, Lehman Brothers noted that they had historically traded at a premium to the ASE Test Nasdaq Shares which Lehman Brothers believes is due to limited availability and lack of adequate liquidity on the Taiwan Stock Exch a nge for ASE Test TDSs. The following table presents the results of this analysis:

Implied Per Share Equity Reference Range for ASE Test		Per Share Consideration
US $12.94 - US $15.30		US $	14.78

Research A nalysts ’ Price Targets Analysis

Lehman Brothers evaluated reports of several publicly available third-party equity research analysts on ASE Test and noted that, based on the latest available broker search on September 4, 2007, only two third-party research analyst firms provided projections for price targets for the ASE Test Nasdaq Shares. Lehman Brothers then evaluated such equity research analysts’ projected price targets for the ASE Test Nasdaq Shares and compared them to the ASE Test Nasdaq Shares’ trading price as of August 31, 2007 and the proposed per share scheme consideration. The following table presents the results of this analysis:

	Period Prior to Announcement
Research Analysts’ Price Targets	Target Price		Per Share Consideration
Average	US $	1 4 .00	US $	14.7 8
Low	US $	13.00
High	US $	15.00

General

In connection with the review of the scheme by the special committee, Lehman Brothers performed a variety of financial and comparative analyses for the purposes of rendering its opinion. The prepa ration of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. In arriving at its opinion, Lehman Brothers considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor considered by it. Furthermore, Lehman Brothers believes that the summary provided and the analyses described above must be considered as a whole and that focusing on any portion of its analyses, without consideri ng all of them, would create an incomplete view of the process underlying Lehman Brothers ’ analyses and opinion. In addition, Lehman Brothers may have given certain analyses and factors more or less weight than other analyses and factors and may have deeme d various assumptions more or less probable than other assumptions . Therefore, the ranges of valuations resulting from any particular analysis described above should not be taken to be Lehman Brothers ’ view of the actual value of ASE Test.

In performing i ts analyses, Lehman Brothers made numerous assumptions with respect to risks associated with industry performance, general business and economic conditions and other matters, many of which are beyond ASE Test ’ s control. Any e stimates contained in Lehman Br others ’ analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates. The analyses were performed solely as part of Lehman Brothers ’ analysis of the fai rness of the scheme consideration, from a financial point of view , to the unaffiliated ASE Test s hare holders and were performed in connection with the delivery by Lehman Brothers of its opinion, dated September 4, 2007, to the special committee. Such analy ses do not purport to be appraisals and do not reflect the prices at which ASE Test Nasdaq Shares or ASE Test TDSs m ay trade following the announcement of the scheme .

The terms of the scheme were arrived at after arm ’ s-length negotiations between the spec ial committee , ASE Inc. and their respective advisors and were unanimously approved by ASE Test ’ s board of directors, with only the independent directors voting and the interested directors abstaining from voting . Lehman Brothers did not recommend any spec ific amount or form of consideration to ASE Test or that any specific amount or form of consideration constituted the only appropriate consideration for the scheme . Lehman Brothers ’ opinion was provided to the special committee to assist it in its consider ation of the scheme . Lehman Brothers ’ opinion does not address any other aspect s of the scheme and does not constitute a recommendation to any ASE Test s hare holder as to how to vote or to take any other action with respect to the scheme . Lehman Brothers ’ o pinion was one of the many factors taken into consideration by the special committee in making its recommendation to the board of directors of ASE Test, and by the board of directors of ASE Test in making its unanimous determination to approve the scheme i mplementation agreement and the transactions contemplated thereby and to recommend the approval and adoption of the scheme by the unaffiliated ASE Test shareholders . Lehman Brothers ’ analyses summarized above should not be viewed as determinative of the op inion of the special committee or the board of directors of ASE Test with respect to the value of ASE Test or of whether the special committee or the board of directors of ASE Test would have been willing to agree to a different amount or form of considera tion.

Lehman Brothers is an internationally recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotia ted underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. The special committee selected Lehman Brothers because of its expertise, reputation and fami liarity with ASE Test and the semiconductor assembly and testing industry generally and because its investment banking professionals have substantial experience in transactions comparable to the scheme .

As compensation for its services in connection with the scheme , ASE Test has agreed to pay Lehman Brothers a financial advisory fee of US $2.0 million, of which US$0.5 million became payable up on the rendering of Lehman Brothers ’ opinion to the special committee and the remainder would becom e payable up on th e completion of the scheme . In addition, ASE Test has agreed to reimburse Lehman Brothers for reasonable out-of-pocket expenses incurred in connection with the scheme and to indemnify Lehman Brothers for certain liabilities that may arise out of its engage ment by the special committee and the rendering of the Lehman Brothers ’ opinion. Lehman Brothers in the past has rendered , and expects in the future to render , investment banking services to ASE Test , ASE Inc. and its affiliates, and expects to receive cus tomary fees for such services. Lehman Brothers or its affiliates have not had any material relationship with ASE Inc., ASE Test or their respective affiliates for the past two years , other than with respect to the services it rendered to the special commi ttee in connection with the proposed scheme.

In the ordinary course of its business, Lehman Brothers actively trades in the debt or equity securities of ASE Test for its own account and for the accounts of its customers and, accordingly, may at any time ho ld a long or short position in such securities.

A copy of the written opinion of Lehman Brothers and of Lehman Brothers ’ written presentation to the special committee has been attached as an exhibit to the Schedule 13E-3 filed with the SEC in connection w ith the scheme. The written opinion of Lehman Brothers is also attached as Appendix B to this scheme document and such written opinion and Lehman Brothers ’ written presentation to the special committee will be made available for inspection and copying at the offices of ASE Test at 10 West Fifth Street, Nantze Export Processing Zone, Kaohsiung, Taiwan, Republic of China during regular business hours by any interested ASE Test share holder or such share holder ’ s designated representative. A copy of the writte n opinion of Lehman Brothers and Lehman Brothers ’ written presentation to the special committee will be mailed by ASE Test to any interested holder of ASE

Test shares or such holder ’ s designated representative, upon written request to ASE Test at 10 West F ifth Street, Nantze Export Processing Zone, Kaohsiung, Taiwan, Republic of China , Attention: Ms. Eileen Sih, at the expense of the requesting share holder .

Lehman Brothers has given and has not withdrawn its written consent to the inclusion of its name, it s written opinion dated September 4, 2007 and extracts from its written presentation dated September 4, 2007 to the special committee and references to such opinion and presentation in this scheme document , in the form and context in which they appear in t his scheme document.

Projected Financial Information

Prior to entering into the scheme implementation agreement, certain projected financial information for fiscal year 2007 prepared by ASE Test’s management, referred to herein as the projected financial information, was made available to the special committee and Lehman Brothers in connection with their respective consideration and evaluation of the scheme. Lehman Brothers used this projected financial information in its financial analyses and in rendering its opinion dated September 4, 2007 to the special committee that the scheme consideration is fair to the unaffiliated ASE Test shareholders from a financial point of view. See “—Opinion of Lehman Brothers” on page [ · ] for a discussion of the analyses performed and the fairness opinion delivered by Lehman Brothers to the special committee. The projected financial information was subsequently provided to ANZ Singapore, the independent financial advisor to the independent directors, when it was engaged to render an opinion on the scheme consideration pursuant to the requirements of the Singapore Code. See “—Opinion of ANZ Singapore” on page [ · ] for a discussion of the analysis performed and the fairness opinion delivered by ANZ Singapore to the independent directors. We have included herein a subset of the most recent projected financial information relating to ASE Test’s 2007 estimated net sales, gross profits, EBITDA, EBIT and net income provided by ASE Test’s management in August 2007 to the special committee and Lehman Brothers, and subsequently to ANZ Singapore, and used by Lehman Brothers and ANZ Singapore in their respective financial analyses and in rendering their respective fairness opinions. This information is included solely for the purpose of providing ASE Test shareholders with access to certain information considered by the special committee and the board of directors of ASE Test in their respective consideration and evaluation of the scheme. The inclusion of this information should not be regarded as an indication that the special committee or the board of directors of ASE Test, Lehman Brothers, ANZ Singapore or any other recipient of this information considered, or now considers, it to be a reliable prediction of future results.

The projected financial information was prepared by ASE Test’s management for internal budgeting and other purposes only, and was not prepared with a view towards public disclosure or towards compliance with the published guidelines of the relevant U.S., Republic of China or Singapore accounting standards, rules or requirements or the guidelines established by the American Institute of Certified Public Accountants with respect to projected financial information. ASE Test’s management does not as a matter of course make public projections as to the company’s future performance or earnings, except that, in its prior earnings releases, ASE Test has announced guidance for the estimated quarter-on-quarter revenue growth and gross margin expectations for the following quarter.

The projected financial information reflects assumptions with respect to industry performance, general business, competitive environment, economic, market and financial conditions and other matters, all of which are difficult to predict and are beyond ASE Test’s control. The projected financial information also reflects numerous estimates and assumptions relating to the business of ASE Test that are inherently subject to economic, market, and other uncertainties, all of which are difficult to predict and many of which are beyond ASE Test’s control. Furthermore, the internal financial forecasts, upon which the projected financial information is based, are subjective in many respects. The projected financial information does not constitute factual information and should not be relied upon as being necessarily indicative of future results. Moreover, there can be no assurance that the projected results will be realized or that actual results will not be significantly higher or lower than projected.

The projections disclosed below were prepared by ASE Test’s management in August 2007, prior to the execution of the scheme implementation agreement and announcement of the scheme, and therefore do not take into account any events or developments that have occurred or may occur after the time they were originally prepared, including, without limitation, any of the potential effects of the scheme.

Since the date of the projections, ASE Test has made publicly available its actual results of operations for the fiscal third quarter ended September 30, 2007 in its report on Form 6-K dated October 31, 2007. In addition,

Appendix G contains the unaudited consolidated financial statements of ASE Test and its subsidiaries for the nine months ended September 30, 2006 and 2007. Readers of this scheme document are cautioned not to place any undue reliance on all or any specific portions of the projected financial information set forth below. No representation or warranty is made with respect to any such information.

As described above under “ —Opinion of Lehman Brothers” on page [ · ], the projected EBITDA and EBIT of ASE Test are adjusted to appropriately take into account stock-based compensation expenses not reflected under ROC GAAP and ASE Test’s 30% shareholding in ASE Korea by adding the estimated proportionate shares of ASE Korea’s EBITDA and EBIT to ASE Test’s estimated EBITDA and EBIT, respectively.

Please refer to “—Opinion of Lehman Brothers” on page [ · ] for a discussion of the definition of EBITDA and EBIT as adjusted and used by Lehman Brothers for purposes of evaluating the scheme and as set forth in this scheme document.

ASE Test’s projected ROC GAAP net income has been adjusted under U.S. GAAP to reflect bonuses to employees, directors and supervisors, stock-based compensation, undistributed earnings tax, and other miscellaneous items as expenditures. The above estimates were based on information available to ASE Test at the time, which was prior to the issuance of its actual results of operations for the nine months ended September 30, 2007.

ASE Test developed the projected financial information based on the following methodology and assumptions:

Projected revenue is derived using a bottom-up approach, which reflects expected revenue to be generated from each customer;

Cost of goods sold is estimated based on detailed projections of each expense item, including raw material, direct and indirect labor, rent, depreciation and amortization expenses;

Fixed costs are estimated based on historical expenses incurred in the fiscal first and second quarter periods of 2007, and variable costs are based on estimates on sales volume, forecasted headcount and other factors; and

Operating expense is comprised of research and development expenses, as well as sales and marketing and general administrative costs, whereby such expenses are estimated based on costs incurred in fiscal first and second quarter periods of 2007, taking into consideration forecasted headcount, salary adjustments, and other relevant factors.

As required by the Singapore Code, Deloitte & Touche, ASE Test’s independent public accountants, and ANZ Singapore, the independent financial advisor to the independent directors, have each issued a letter in relation to the projected financial information, attached as Appendices I and J to this scheme document, respectively. The letters attached as Appendices I and J are intended solely for the information and use of the unaffiliated ASE Test shareholders at the court meeting as required by the Singapore Code and should not be used by anyone other than the specified parties.

Deloitte & Touche has agreed in writing, and has not withdrawn such agreement, to the inclusion of its name, its report dated December 11, 2007, in relation to the unaudited consolidated financial statements of ASE Test and its subsidiaries for the three months and nine months ended September 30, 2006 and 2007, and its letter dated November 8, 2007, in relation to the projected financial information, and references to such report and letter in this scheme document, in the form and context in which they appear in this scheme document.

Opinion of ANZ Singapore

Following the execution of the scheme implementation agreement, in response to an application by ASE Inc., the SIC confirmed in its ruling dated October 17, 2007 that the Singapore Code applies to the scheme, subject to certain exceptions. See “—Regulatory Matters” below.

In compliance with the SIC ruling and the provisions of the Singapore Code, on November 15, 2007, the independent directors engaged ANZ Singapore as the independent financial advisor to advise them on the scheme. ANZ Singapore, based upon and having considered the information that has been made available to it and the factors set out in its written opinion, is of the view that, as of the date set forth in its opinion, the scheme consideration to be received by ASE Test shareholders (other than ASE Inc. and its subsidiaries) is fair to such ASE Test shareholders from a financial point of view. In arriving at its opinion, ANZ Singapore took into consideration the factors and performed the financial analyses set forth in its written opinion, which is attached as Appendix K to this scheme document and incorporated herein by reference, including, among others, the following:

(i)

ASE Test’s (x) enterprise value, referred to herein as EV, to EBITDA for the last 12 months and normalized by eliminating non-recurring items, referred to herein as EV / LTM EBITDA, and (y) EV to consensus EBITDA estimates for fiscal year 2007, referred to herein as EV /FY07E EBITDA, as implied by the scheme consideration, exceed both the mean and median EV / LTM EBITDA and EV / FY07E EBITDA multiples of the selected broadly comparable medium capitalization companies (as described in ANZ Singapore’s opinion);

(ii)

ASE Test’s (x) EV to EBIT for the last 12 months and normalized by eliminating non-recurring items, referred to herein as EV / LTM EBIT, and (y) EV to consensus EBIT estimates for fiscal year 2007, referred to herein as EV / FY07E EBIT, as implied by the scheme consideration, exceed both the mean and median EV / LTM EBIT and EV / FY07E EBIT multiples of the selected broadly comparable medium capitalization companies (as described in ANZ Singapore’s opinion);

(iii)

ASE Test’s (x) price to earnings per share ratio for the last 12 months and normalized by eliminating non-recurring items, referred to herein as LTM PER, and (y) consensus PER estimates for fiscal year 2007, referred to herein as FY07E PER, as implied by the scheme consideration, exceed both the mean and median LTM PER and FY07E PER multiples of the selected broadly comparable medium capitalization companies (as described in ANZ Singapore’s opinion);

(iv)

ASE Test’s price to net tangible assets per share, referred to herein as Price / NTA, as implied by the scheme consideration, exceeds both the mean and median Price / NTA multiples of the selected broadly comparable medium capitalization companies (as described in ANZ Singapore’s opinion);

(v)

the price of ASE Test Nasdaq Shares for the 12-month period prior to September 4, 2007, the date of the announcement of the execution of the scheme implementation agreement, up to August 31, 2007, the last full trading date of ASE Test Nasdaq Shares on The NASDAQ Global Market prior to September 4, 2007, had outperformed against the NASDAQ Composite Index and the Philadelphia Stock Exchange Semiconductor Index, and underperformed against the Comparable Companies Index (as described in ANZ Singapore’s opinion); the price of ASE Test Nasdaq Shares for the 12-month period prior to September 4, 2007, up to the date set forth in the written opinion, had outperformed the NASDAQ Composite Index, the Philadelphia Stock Exchange Semiconductor Index and the Comparable Companies Index;

(vi)

the scheme consideration represents a 25.6% premium to the last transacted price of ASE Test Nasdaq Shares on The NASDAQ Global Market of US$11.77 as of August 31, 2007, the date of the last full trading day of ASE Test Nasdaq Shares on the NASDAQ Global Market prior to the announcement of the scheme, and a premium to the volume weighted average price, referred to

herein as VWAP, of ASE Test Nasdaq Shares over the 30-day, 60-day, 90-day and 180-day periods preceding September 4, 2007, except in the case of ASE Test TDS where the scheme consideration represents a small discount to the VWAP over the 60-day and 90-day periods for ASE Test TDSs;

(vii)

the premium implied by the scheme consideration exceeds the mean and median of the premia to the last traded price before the respective announcement dates and the 7-day, 30-day average prices of the selected privatizations set forth in the written opinion but is below the mean and median of the premia to the 90-day average prices of such selected privatizations;

(viii)

the valuation multiples implied by the scheme consideration may be considered to be generally comparable to the transaction multiples implied by the privatization of United Test and Assembly Center Ltd.;

(ix)

the trading volumes of ASE Test Nasdaq Shares and ASE Test TDSs appear to be relatively low; and

(x)

as of the date set forth in the written opinion, there is no publicly available evidence of an alternative offer for ASE Test ordinary shares from any third party for a consideration that is above the terms of the scheme as proposed by ASE Inc.

In evaluating the scheme and rendering its opinion, ANZ Singapore used the same projected financial information used by, and calculated EBITDA and EBIT consistent with the methodology used by, Lehman Brothers in evaluating the scheme and rendering its opinion, except that ANZ Singapore used normalized EBITDA and EBIT that eliminated non-recurring items. See “—Opinion of Lehman Brothers” beginning on page [ · ] for a discussion of the definition of EBITDA and EBIT as calculated by, and “—Projected Financial Information” beginning on page [ · ] for a discussion of the projected financial information used by, Lehman Brothers in evaluating the scheme and rendering its opinion.

We encourage you to read the written opinion of ANZ Singapore in its entirety, including the description of the assumptions made, procedures followed, factors considered and limitations upon the review undertaken by ANZ Singapore in rendering its opinion. The full text of the written opinion of ANZ Singapore is attached as Appendix K to this scheme document.

ANZ Singapore’s opinion is based upon the market, economic, industry, monetary and other applicable conditions, and the information made available to ANZ Singapore, as of the date set forth in its written opinion.

The terms of the scheme were arrived at after arm’s-length negotiations between the special committee and ASE Inc. and their respective advisors and were unanimously approved by the board of directors of ASE Test, with only the independent directors voting and the interested directors abstaining from voting. ANZ Singapore did not recommend any specific amount or form of scheme consideration or that any specific amount or form of consideration constituted the only appropriate consideration for the scheme. ANZ Singapore’s opinion is not intended to be and does not constitute a recommendation to any ASE Test shareholder as to how such shareholder should vote in connection with the scheme. ANZ Singapore was not requested to opine as to, and ANZ Singapore’s opinion does not address, ASE Test’s underlying business decision to proceed with or effect the scheme.

In rendering its opinion, ANZ Singapore has not had regard to the general or specific investment objectives, tax position, financial situation, tax status, risk profiles or unique needs and constraints or particular circumstances of any individual ASE Test shareholder. As different ASE Test shareholders would have different investment objectives and profiles, ANZ Singapore recommends that any individual ASE Test shareholder who may require advice in the context of his or her specific investment portfolio should consult his or her legal, financial, tax or other professional advisor.

ANZ Singapore is a recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, competitive bids, private placements and valuations for corporate and other purposes. The independent directors selected ANZ Singapore because of its expertise, reputation and its substantial experience in acting as independent financial advisor in scheme of arrangements under Singapore law and other transactions comparable to the scheme.

As compensation for its services in connection with the scheme, ASE Test has agreed to pay ANZ Singapore a financial advisory fee of US$400,000, of which US$200,000 became payable upon submission of ANZ Singapore’s draft opinion to the independent directors and the remainder will become payable upon the delivery of the signed opinion of ANZ Singapore to the independent directors. In addition, ASE Test has agreed to reimburse ANZ Singapore for reasonable out-of-pocket expenses incurred in connection with the scheme and to indemnify ANZ Singapore for certain liabilities that may arise out of its rendering of services under the engagement by the independent directors and the rendering of its opinion. Neither ANZ Singapore nor any of its affiliates has had any material relationship with ASE Inc., ASE Test or any of their respective affiliates in the past two years, other than with respect to the services it rendered to the independent directors in connection with the scheme.

A copy of the written opinion of ANZ Singapore has been attached as an exhibit to the Schedule 13E-3 filed with the SEC in connection with the scheme. The written opinion of ANZ Singapore is also attached as Appendix K to this scheme document, and such written opinion will be made available for inspection and copying at the offices of ASE Test at 10 West Fifth Street, Nantze Export Processing Zone, Kaohsiung, Taiwan, Republic of China during regular business hours by any interested shareholder of ASE Test shares or such shareholder’s designated representative. A copy of the written opinion of ANZ Singapore will be mailed by ASE Test to any interested ASE Test shareholder or such shareholder’s designated representative, upon written request to ASE Test at 10 West Fifth Street, Nantze Export Processing Zone, Kaohsiung, Taiwan, Republic of China, Attention: Ms. Eileen Sih, at the expense of the requesting shareholder.

ANZ Singapore has given and has not withdrawn its written consent to the inclusion of its name, its opinion in relation to the scheme set out in its letter to the independent directors dated [ · ], its letters each dated [ · ] in relation to the unaudited consolidated financial statements of ASE Test and its subsidiaries for the nine months ended September 30, 2007 and the projected financial information, respectively, and references to such opinion and letters in this scheme document, in the form and context in which they appear in this scheme document.

Recommendation of ASE Test’s Independent Directors

ASE Test shareholders should read and consider carefully: (i) the recommendation of the special committee to the board of directors of ASE Test and the recommendation of the board of directors of ASE Test (with only the independent directors voting and the interested directors abstaining from voting) to the unaffiliated ASE Test shareholders as to the approval and adoption of the scheme; (ii) the opinion of Lehman Brothers on the fairness of the scheme consideration from a financial point of view attached to this scheme document as Appendix B; and (iii) the opinion of ANZ Singapore on the fairness of the scheme consideration from a financial point of view attached to this scheme document as Appendix K, each in its entirety, before deciding whether or not to vote in favor of the proposal to approve and adopt the scheme at the court meeting.

Pursuant to the Singapore Code, the independent directors are required to make a recommendation to ASE Test shareholders (other than ASE Inc. and its subsidiaries) in relation to the scheme. Having considered the terms of the scheme, the recommendations of the special committee and the board of directors of ASE Test (with only the independent directors voting and the interested directors abstaining from voting), the opinion of Lehman Brothers and the opinion of ANZ Singapore, the independent directors recommend that you vote FOR the approval and adoption of the scheme.

In giving the above recommendation, the independent directors have not had regard to the specific objectives, financial situation or unique needs and constraints of any individual ASE Test shareholder. As different shareholders may have different investment objectives and profiles, any individual ASE Test shareholder who may require advice in the context of his or her specific investment portfolio should consult his or her stockbroker, bank manager, legal advisor, accountant, tax, financial or other professional advisor immediately.

ASE Inc.’s Reasons for Effecting the Scheme; Position as to Fairness

ASE Inc.’s reasons for effecting the scheme include the following:

the scheme is intended to simplify the corporate structure of the ASE group by making ASE Test a wholly-owned subsidiary of ASE Inc., thereby reducing the costs and administrative burden associated with operating ASE Test as a publicly traded company, including the costs associated with regulatory filings and compliance requirements;

the scheme is intended to enhance the promotion of one common brand and identity and eliminate investor confusion between ASE Inc. and ASE Test;

the scheme is intended to increase flexibility of ASE Inc. to make investment and other business decisions within the ASE group, including efficient allocation of resources between the various businesses within the ASE group; and

provide liquidity to ASE Test shareholders at a premium price.

Because ASE Inc. indirectly owns a majority of the outstanding ASE Test ordinary shares as of November 30, 2007 and is deemed an “affiliate” of ASE Test that is engaging in a “going private” transaction under Rule 13e-3, it is required to consider the fairness of the scheme to the unaffiliated ASE Test shareholders. ASE Inc. is making the statements in this section solely for the purpose of complying with the requirements of Rule 13e-3, and related rules under the Exchange Act, and its view should not be construed as a recommendation to any unaffiliated ASE Test shareholder as to how to vote with respect to the scheme.

ASE Inc. did not participate in the deliberation process of the special committee and board of directors of ASE Test relating to the scheme, and all interested directors of ASE Test, due to their affiliation with ASE Inc., abstained from such deliberation process and from the determination and approval by the board of directors of ASE Test in respect of the scheme. However, ASE Inc. found persuasive the conclusions of the special committee and the board of directors of ASE Test as to the substantive and procedural fairness of the scheme to the unaffiliated ASE Test shareholders. See “—ASE Test’s Reasons for the Scheme; Recommendation of ASE Test’s Board of Directors” beginning on page [ · ].

Accordingly, ASE Inc. believes that the scheme is substantively and procedurally fair to the unaffiliated ASE Test shareholders because, among other things:

the per share scheme consideration represents:

a premium of approximately 25.6% above the last transacted price of each ASE Test Nasdaq Share on The NASDAQ Global Market of US$11.77 as of August 31, 2007, the last full trading day of ASE Test Nasdaq Shares on The NASDAQ Global Market prior to the announcement of the scheme;

a premium of approximately 28.1% above the average of the last transacted prices of ASE Test Nasdaq Shares on The NASDAQ Global Market of US$11.54 over the one-week period ended August 31, 2007, the last full trading day of ASE Test Nasdaq Shares on the NASDAQ Global Market prior to the announcement of the scheme;

a premium of approximately 25.6% above the average of the last transacted prices of ASE Test Nasdaq Shares on The NASDAQ Global Market of US$11.77 over the one-month period ended August 31, 2007, the last full trading day of ASE Test Nasdaq Shares on the NASDAQ Global Market prior to the announcement of the scheme; and

a premium of approximately 30.9% above the average of the last transacted prices of ASE Test Nasdaq Shares on The NASDAQ Global Market of US$11.29 over the twelve-month period ended August 31, 2007, the last full trading day of ASE Test Nasdaq Shares on the NASDAQ Global Market prior to the announcement of the scheme;

the efforts made by the special committee and its financial and legal advisors to negotiate and execute a scheme implementation agreement containing financial and other terms favorable to ASE Test, the fact that the scheme consideration and the terms and conditions of the scheme implementation agreement were arrived at after arm’s-length negotiations between ASE Inc. and the special committee (advised by financial and legal advisors) on a willing-seller, willing-buyer basis, after multiple negotiating sessions and discussions , which resulted in an increase in the scheme consideration from US$14.30 per ASE Test Nasdaq Share to US$14.78 per ASE Test Nasdaq Share, and the business judgment of the special

committee that, based upon the negotiations that had transpired, a price higher than US$14.78 could not likely be obtained;

the written opinion of the financial advisor to the special committee that, as of the date of the scheme implementation agreement, the scheme consideration is fair to the unaffiliated ASE Test shareholders from a financial point of view;

the written opinion of the IFA that, as of the date of the opinion, the scheme consideration to be received by ASE Test shareholders (other than ASE Inc. and its subsidiaries) is fair to such ASE Test shareholders from a financial point of view;

the scheme provides for an all cash consideration, which allows the unaffiliated ASE Test shareholders to realize their investment for a cash consideration that is at a significant premium over the market prices of ASE Test Nasdaq Shares and ASE Test TDSs prior to the announcement of the scheme, an option which may not otherwise be readily available to such shareholders due to the low trading liquidity of ASE Test Nasdaq Shares and ASE Test TDSs;

ASE Inc.’s indirect ownership of a majority of the outstanding ASE Test ordinary shares as of the date of this scheme document and the fact that, as a practical matter, ASE Test is unlikely to attract and complete any alternative acquisition proposal given ASE Inc.’s ownership position in ASE Test;

the fact that the terms of the scheme implementation agreement contain a “fiduciary-out” exception as described below in “The Scheme Implementation Agreement—Non-Solicitation; Fiduciary-Out”, which allows ASE Test, under certain circumstances, to change or withdraw its recommendation and terminate the scheme implementation agreement;

the likelihood and anticipated timing of the receipt of required regulatory approvals for the scheme and the completion of the scheme;

the financial commitment obtained by ASE Inc., that the scheme is not conditioned upon the receipt of financing by ASE Inc., and that ASE Inc. has the financial resources to complete the scheme;

the scheme is structured so that t he affirmative vote of a majority in number of the unaffiliated ASE Test shareholders present and voting, either in person or by proxy, at the court meeting, representing not less than 75% in value of ASE Test ordinary shares held by the unaffiliated ASE T est shareholders present and voting, either in person or by proxy, at the court meeting, is required for its approval and adoption;

the quorum for the court meeting is voluntarily set by the parties to require the presence at the court meeting, in person or by proxy, of unaffiliated ASE Test shareholders holding one-third of the outstanding ASE Test ordinary shares held by all unaffiliated ASE Test shareholders, which is a higher threshold than that required by Singapore law or the Articles of Associatio n of ASE Test (which requires a quorum consisting of the presence of ASE Test shareholders holding not less than one-third of the outstanding ASE Test ordinary shares held by all ASE Test shareholders);

t he special committee consisted entirely of directors who are n ot affiliated with ASE Inc. and are independent for purposes of the scheme;

the fact that the special committee had the ultimate authority on behalf of ASE Test to decide whether or not to proceed with a transaction, subject to the approval of the scheme implementation agreement by the board of directors of ASE Test;

t he special committee retained and received advice and assistance from its own financial and legal advisors, each of which has extensive experience in transactions similar to the s cheme and in evaluating, negotiating and analyzing the terms of the scheme;

t he financial and legal advisors of the special committee reported directly to the special committee and took direction s exclusi vely from the special committee; and

members of the special committee will not receive any consideration pursuant to the scheme that is different from that received by any other unaffiliated ASE Test shareholder.

ASE Inc. believes that the scheme is substantively and procedurally fair for all the reasons listed above. In this regard, ASE Inc. notes that the special committee and the board of directors of ASE Test believed the special committee could represent effectively the interests of the unaffiliated ASE Test shareholders without retaining an unaffiliated representative to act solely on behalf of such shareholders, as the use of a special committee is a well-recognized mechanism to achieve procedural fairness in “going private” transactions such as the scheme. See “—ASE Test’s Reasons for the Scheme; Recommendation of Board of Directors” beginning on page [ · ].

ASE Inc. did not consider liquidation value because it considered ASE Test to be a viable going concern business. ASE Inc. indirectly holds a majority of the outstanding ASE Test ordinary shares as of the date of this scheme document and does not wish to liquidate ASE Test. In addition, ASE Inc. did not consider net book value, which is an accounting concept, as a factor because it believed that net book value is not a material indicator of the value of ASE Test as going concern, but rather is indicative of historical costs. ASE Inc. considered the going concern value of ASE Test, by considering, among other things, the financial presentation regarding the compilation of publicly available information with respect to ASE Test prepared by Citi, the financial advisor to ASE Inc. See “Presentation of Citi” for a summary of Citi’s presentation to ASE Inc.

Since ASE Inc. relied on its own analysis and conclusions in forming its belief as to the fairness of the scheme to the unaffiliated ASE Test shareholders, it did not adopt the conclusions of the special committee or the board of directors of ASE Test with respect to such fairness and, accordingly, did not adopt the analysis or opinion of the special committee’s financial advisor.

The foregoing discussion of the information and factors considered and given weight by ASE Inc. in connection with the fairness of the scheme implementation agreement and the scheme is not intended to be exhaustive, but is believed to include all material factors considered by ASE Inc. ASE Inc. did not find it practicable to, and did not, quantify, rank or otherwise assign relative weights to the foregoing factors in reaching its position as to the fairness of the scheme implementation agreement and the scheme, nor did it evaluate whether these factors were of equal importance. ASE Inc. believes that these factors provide a reasonable basis for its position that the scheme is fair to the unaffiliated ASE Test shareholders.

On October 31, 2007, ASE Inc. issued a statement announcing that it does not intend to revise the scheme consideration. Accordingly, pursuant to the provisions of Rule 20.2 of the Singapore Code, ASE Inc. will not be permitted to increase the scheme consideration or amend the terms of its offer in connection with the scheme. Furthermore, in the event the scheme does not become effective due to the failure to obtain the requisite shareholder approval, pursuant to the provisions of Rule 33.1 of the Singapore Code, ASE Inc. will not be permitted to make a further or new offer for the shares of ASE Test for a period of 12 months from the date of the court meeting, unless it obtains the prior consent of the SIC.

Presentation of Citi

In connection with ASE Inc.’s consideration of the proposed acquisition of the outstanding ASE Test ordinary shares held by ASE Test shareholders (other than ASE Inc. and its subsidiaries), ASE Inc. engaged Citi to act as its financial advisor. On August 30, 2007, ASE Inc. was preparing to meet with the special committee to negotiate the terms of the scheme, including the scheme consideration. Citi had compiled certain public data, for the information of and use by ASE Inc., which were subsequently updated as requested by management of ASE Inc. to reflect the views of management and the increase in the scheme consideration offered by ASE Inc., referred to herein as the Citi presentation. Such public data included the historical share price performance of ASE Test Nasdaq Shares and ASE Test TDSs, valuation multiples of ASE Test’s comparable companies derived using The Institutional Brokers Estimate System, or IBES, consensus estimates and other publicly available data, and data on precedent transactions with a focus on the tender offer by Singapore Technologies Semiconductors to acquire STATS ChipPac Ltd. and the offer by Affinity Equity Partners and TPG Capital to acquire United Test and Assembly Center Ltd by way of a scheme of arrangement under Singapore law. The IBES consensus estimates used in the Citi presentation were estimates from institutional stockbrokers and were not prepared by Citi. Citi did not

prepare any financial projections nor did it carry out any independent verification of such estimates and did not endorse or otherwise pass judgment on such estimates.

The full text of the Citi presentation will be made available for inspection and copying at the offices of ASE Inc. at Room 1901, TWTC International Trade Building, 19F, 333, Keelung Road., Sec. 1, Taipei 110, Taiwan, Republic of China during regular business hours by any interested holder of ASE Test Nasdaq Shares or ASE Test TDSs or such holder’s designated representative. A copy of the Citi presentation will be mailed by ASE Inc. to any interested ASE Test shareholder or such shareholder’s designated representative, upon written request to ASE Inc. at Room 1901, TWTC International Trade Building, 19F, 333, Keelung Road., Sec. 1, Taipei 110, Taiwan, Republic of China, Attention: Mr. Freddie Liu, at the expense of the requesting shareholder.

The Citi presentation is necessarily based on financial, economic, market and other conditions, and the public information available as of August 30, 2007. Citi was not engaged to, and did not, provide any opinion as to the fairness or reasonableness of the transaction, the scheme consideration, supporting public data compiled by Citi for use by ASE Inc. in determining the per share scheme consideration, or otherwise. The Citi presentation does not constitute, and should not be viewed as a recommendation to any shareholder of ASE Test as to whether to vote his or her ASE Test ordinary shares in favor of the scheme or any other transaction.

Citi has given and has not withdrawn its written consent to the inclusion of its name and the extracts from the Citi presentation and references to such presentation in this scheme document, in the form and context in which they appear in this scheme document.

The data compiled by Citi included the following relevant information:

ASE Test Nasdaq Share Price Performance

Citi presented a chart depicting share price performance of ASE Test Nasdaq Shares over the one-year period from August 29, 2006 through August 28, 2007, which showed the one-year, six-month, three-month, one-month and one-week average sale prices for ASE Test Nasdaq Shares of US$11.27, US$12.66, US$13.33, US$11.94 and US$11.45, respectively.

Comparable Company Trading Analysis

Citi compiled data summarizing the valuation multiples of comparable companies in the same sector as ASE Test. The comparable companies for ASE Test consisted of Powertech Technology Inc., Global Testing Corp., King Yuan Electronics Company Ltd., and United Test and Assembly Center Ltd., each of which has greater than 50% of its revenues in the semiconductor testing-oriented business.

Share Price Performance of ASE Inc. and ASE Test’s Peers

Citi presented charts comparing the share price performance of ASE Test to that of ASE Inc. and ASE Test’s peers, such as Amkor Technology Inc., United Test and Assembly Center Ltd. and STATS ChipPAC Ltd., for the periods from May 28, 2007 through August 28, 2007 and from August 14, 2007 through August 28, 2007.

Precedent Transactions

Citi compiled data on three relevant precedent transactions: (i) the terminated offer by the Carlyle Group to acquire ASE Inc.; (ii) the tender offer by Singapore Technologies Semiconductors to acquire STATS ChipPAC Ltd. and (iii) the offer by Affinity Equity Partners and TPG Capital to acquire United Test and Assembly Center Ltd by way of a scheme of arrangement under Singapore law. The data included the percentage of shares to be acquired, offer price per share, transaction value, implied valuation multiples for ASE Test such as implied equity value and implied firm value, ratio of firm value to estimated EBITDA of ASE Test for 2007, ratio of firm value to estimated EBIT of ASE Test for 2007, estimated 2007 earnings per share of ASE Test, price to book value of ASE Test, and offer premium based on the one-day share price of ASE Test and the 30-day average share price of ASE Test.

Miscellaneous

ASE Inc. engaged Citi based on its qualifications, expertise and reputation. Citi is an internationally recognized financial services firm and, as part of its investment banking activities, regularly engages in analyzing businesses and securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and performing analysis for estate, corporate and other purposes.

Citi and its affiliates have had a longstanding relationship with both ASE Inc. and ASE Test. The business relationship includes acting as depository agent and custodian for the ASE Inc. ADSs that trade on the New York Stock Exchange.

In the ordinary course of business, Citi and its affiliates may provide loan, cash management services, deposit and trade facilities, underwriting, brokerage and investment banking advisory services to ASE Inc. and its affiliates. In addition, Citi may hold or actively trade in securities of ASE Inc., ASE Test or those of their respective affiliates for Citi’s own account and for the account of Citi’s customers and, accordingly, may at any time hold a long or short position in such securities.

As a matter of public record, in August 2005 Citibank Taiwan arranged a US$78 million term loan syndication for ASE Test, and in June 2006 Citibank Taiwan arranged a US$300 million equivalent NT$ denominated term loan syndication for ASE Inc.

For the services that Citi and its affiliates have provided and continue to provide to ASE Inc., ASE Test and their respective affiliates, Citi has earned and will earn customary compensation.

Pursuant to an engagement letter dated September 3, 2007 between ASE Inc. and Citi, ASE Inc. agreed to pay Citi a transaction fee upon (i) the approval of the scheme by the requisite majority of the unaffiliated ASE Test shareholders and (ii) the successful completion of the scheme, based on the scheme becoming effective. ASE Inc. also agreed to reimburse Citi for its reasonable out-of-pocket expenses, including the reasonable fees and expenses of its legal counsel, up to the agreed upon amount set forth in such engagement letter. ASE Inc. has agreed to indemnify Citi and its related persons against certain liabilities arising out of or in connection with Citi’s engagement under the engagement letter.

Effects of the Scheme

On the effective date of the scheme, all ASE Test ordinary shares held by ASE Test shareholders (other than ASE Inc. and its subsidiaries) will be transferred to ASE Inc. for the scheme consideration of: (i) US$14.78 for each ASE Test Nasdaq Share; and (ii) the NT$ equivalent of US$0.185 for each share of ASE Test TDS (based on the prevailing exchange rate calculated in the manner described on page [ · ] of the scheme document).

Upon the effectiveness of the scheme: (i) each in-the-money ASE Test option that remains outstanding as of the books closure date (whether vested or unvested as of the effective date of the scheme) will be deemed to have been exercised as of the books closure date by ASE Test on behalf of the option holder on a cashless basis through a broker, and the ASE Test ordinary shares issued upon such mandatory exercise of the option will be acquired by ASE Inc. for the scheme consideration of US$14.78 per ASE Test Nasdaq Share in cash, and as a result the option holder will receive a cash payment equal to the excess of the per share scheme consideration over the per share exercise price of the option, less any interest, fees and charges of the broker; and (ii) each out-of-the-money ASE Test option that remains outstanding as of the books closure date (whether vested or unvested as of the effective date of the scheme) will be cancelled without any payment to the option holder. See “The Scheme Implementation Agreement—Treatment of Options” on page [ · ].

If the scheme becomes effective, the ASE Test shareholders (other than ASE Inc. and its subsidiaries) will cease to have ownership interests in ASE Test and rights as shareholders of ASE Test, and, as a result, will not participate in any future earnings and growth of ASE Test. Further more , if the scheme becomes effecti ve, ASE Test will become an indirect wholly-owned subsidiary of ASE Inc., and ASE Test Nasdaq Shares will be delisted from The NASDAQ Global Market while ASE Test TDSs will be delisted from the Taiwan Stock Exchange. In addition,

registration of ASE Test ordinary shares under the Exchange Act will terminate upon application to the SEC , and ASE Test will no longer be required to file periodic reports with the SEC.

A benefit of the scheme to ASE Inc. is that ASE Test’s future earnings and growth will be solely for the account of ASE Inc. and not the other existing ASE Test shareholders. The detriments of the scheme to ASE Inc. are the risks that ASE Test will decrease in value following the scheme, the incurrence by ASE Inc. of approximately US$750 million of long-term debt and the payment of approximately US$8.4 million in estimated fees and expenses related to the scheme. See “—Financing Arrangements” and “—Fees and Expenses” beginning on pages [ · ] and [ · ], respectively.

Plans Following the Scheme

If the scheme becomes effective, ASE Inc. and ASE Test have no current intentions to make any material changes to the existing businesses of ASE Test and its subsidiaries, restructure the capital structure of ASE Test, redeploy the fixed assets of ASE Test and its subsidiaries, or discontinue the employment of existing employees of ASE Test and its subsidiaries. However, neither ASE Inc. nor ASE Test has ruled out the possibility of any changes in the future if and when they think that such changes are in the best interests of ASE Test and its subsidiaries.

If the scheme becomes effective, ASE Test will become an indirect wholly-owned subsidiary of ASE Inc., and ASE Inc. may make changes to the board of directors or the management of ASE Test as it deems appropriate. Following the effectiveness of the scheme, ASE Inc. intends to undertake a review of restructuring options to optimize operational efficiencies of ASE Test and its subsidiaries and does not anticipate any redundancies of employees of ASE Test and its subsidiaries.

Effects on ASE Test if the Scheme Does Not Become Effective

If the scheme is not approved and adopted by the requisite majority of the unaffiliated ASE Test shareholders at the court meeting, or the scheme does not become effective or is terminated for any reason, ASE Test ordinary shares will not be transferred to ASE Inc., and ASE Test shareholders will not receive any payment for their ASE Test Nasdaq Shares or ASE Test TDSs as contemplated by the scheme. Instead, ASE Test will remain a publicly traded company, and ASE Test Nasdaq Shares and ASE Test TDSs will continue to be listed and traded on The NASDAQ Global Market and the Taiwan Stock Exchange, respectively. Furthermore, pursuant to the provisions of Rule 33.1 of the Singapore Code, if the scheme does not become effective due to the failure to obtain the requisite shareholder approval at the court meeting, ASE Inc. will not be permitted to make a further or new offer for the shares of ASE Test for a period of 12 months from the date of the court meeting, unless it obtains the prior consent of the SIC.

If the scheme does not become effective or is terminated for any reason, it is expected that the management of ASE Test will operate the business of ASE Test in a manner similar to that in which it is being operated today, and that ASE Test shareholders will continue to be subject to the same risks and opportunities as they are currently exposed to, including, among other things, the nature of the semiconductor industry on which ASE Test’s business largely depends, and general industry, economic and market conditions. Accordingly, if the scheme does not become effective or is terminated for any reason, there can be no assurance as to the effect of these risks and opportunities on the future value of ASE Test Nasdaq Shares and ASE Test TDSs. If the scheme is not approved and adopted by the unaffiliated ASE Test shareholders or if the scheme does not become effective or is terminated for any reason, there can be no assurance that any other similar or comparable transaction will be offered, or that the business, prospects or results of operations of ASE Test will not be materially and adversely impacted.

Accounting Treatment of the Scheme

The scheme is expected to be accounted for using the purchase method of accounting for financial accounting purposes, whereby the estimated purchase price would be allocated to assets and liabilities of ASE Test based on their relative fair values in accordance with ROC GAAP, ROC Statement of Financial Accounting Standards No. 5 “Long-term Investments under Equity Method” and No. 25 “Business Combinations”, U.S. GAAP and U.S. Statement of Financial Accounting Standards No. 141 “Business Combinations”.

Financing Arrangements

The scheme is not subject to any financing conditions. The source of funds for the payment by ASE Inc. of the scheme consideration is expected to consist of a combination of ASE Inc.’s existing cash and cash equivalents, as well as the proceeds from the financing committed for the purpose of the scheme. On September 4, 2007, ASE Inc. entered into a commitment letter with Citibank Taiwan, pursuant to which Citibank Taiwan committed to provide a term credit facility, referred to herein as the facility, to ASE Inc., and Citigroup Global Markets Asia Limited agreed to act as the arranger of the facility. The documentation governing the facility has not been finalized and, accordingly, the actual terms of the facility may differ from those described below. In addition, Citigroup Taiwan, as financial advisor to ASE Inc., has confirmed that sufficient financial resources are available to ASE Inc. to satisfy the aggregate scheme consideration and amounts payable by ASE Inc. in respect of the treatment of outstanding ASE Test options in connection with the scheme. This confirmation was provided by Citigroup Taiwan to satisfy the requirements of the Singapore Code. Other than the arrangements described in this section, ASE Inc. does not currently have alternative arrangements or plans for the financing of the scheme.

Conditions Precedent to Citibank’s Commitment

The commitment of Citibank Taiwan and Citigroup Global Markets Asia Limited, collectively referred to herein as Citibank, to provide the facility is subject to the satisfaction or waiver of various conditions, including: (i) the execution of definitive documentation governing the facility and the absence of any event which would entitle ASE Inc. to be relieved of its obligation to acquire ASE Test ordinary shares under the scheme or to terminate the scheme implementation agreement; (ii) the accuracy and completeness of all representations made to Citibank by ASE Inc. and all information ASE Inc. furnished to Citibank in respect of the scheme; (iii) the compliance by ASE Inc. with the terms of the commitment letter and related documents; (iv) the payment in full of all fees, expenses and other amounts payable pursuant to the commitment letter and related documents; (v) the granting by ASE Inc. to Citibank of the option to act as the sole book runner, sole lead manager, placing agent, sole arranger and/or other similar roles on a sole basis in connection with any refinancing or partial refinancing of the facility that takes place within 60 months from the date of the commitment letter; and (vi) the granting by ASE Inc. to Citibank of the right of first refusal for certain derivatives transactions in connection with the facility.

Termination of Citibank’s Commitment

Citibank’s commitment pursuant to the commitment letter will automatically terminate upon the earlier of the execution of definitive documentation governing the facility or March 3, 2008, as extended pursuant to an amendment to the commitment letter dated November 30, 2007. In addition, the commitment letter may be terminated by Citibank if it believes any condition precedent to the commitment is or may not be satisfied by ASE Inc., or if ASE Inc. refuses to accept the pricing changes required by Citibank in connection with the syndication of the facility, subject to the payment of a fee.

The Facility

General. The facility will be an NT$ term loan facility for an amount up to NT$24,750 million. The aggregate amount required to be paid by ASE Inc. in connection with the scheme is estimated to be approximately US$871.5 million, consisting of: (i) approximately US$744.3 million for the aggregate scheme consideration payable to the ASE Test shareholders (other than ASE Inc. and its subsidiaries); (ii) approximately US$122.9 million for the aggregate payment to the holders of outstanding ASE Test options; and (iii) approximately US$4.3 million for the payment of transaction fees, costs and expenses.

Conditions Precedent to Drawdown . The drawdown of the facility is expected to be subject to the satisfaction or waiver of various conditions, including, but not limited to: (i) the execution of definitive documentation governing the facility and the satisfaction or waiver of the conditions to the scheme as set forth in the scheme implementation agreement; (ii) the receipt of all necessary approvals in connection with the scheme and the financing of the scheme; and (iii) evidence that ASE Inc. has sufficient funds (including the facility) to make the required payments pursuant to the scheme.

Term . The facility is expected to have a five-year term, subject to any extension pursuant to the exercise by any lender of its one-time option to put back to the borrower its residual outstanding loan amount at the end of the 36 ^th month from closing of the facility.

Interest Rate . The facility is expected to bear interest at a floating rate based upon the 90-day primary commercial paper rate plus an agreed margin ranging from 0.45% to 0.65% per annum, to be adjusted semi-annually. However, Citibank has the right to change the pricing of the facility upon notice to ASE Inc. if such change is deemed advisable in the judgment of Citibank to ensure a successful syndication of the facility, provided that ASE Inc. may terminate the facility if it does not accept the pricing changes subject to the payment of a fee.

Repayment . Principal repayments are expected to be made in eight unequal installments throughout the term of the facility. ASE Inc. may also voluntarily prepay the facility in whole or in part without premium or penalty subject to certain minimum repayment amount and notice period requirements.

Other Terms . The definitive documentation governing the facility is expected to contain customary representations and warranties, customary affirmative and negative covenants and financial maintenance covenants and customary events of default.

Fees and Expenses

The scheme implementation agreement provides that ASE Test and ASE Inc. will each bear their respective fees, costs and expenses incurred in connection with the scheme implementation agreement. The following table sets forth the estimated fees, costs and expenses expected to be incurred by ASE Test and ASE Inc.:

Filing fees	US$	100,000
Financial advisor fees and expenses		4,000,000
Legal fees and expenses		4,000,000
Printing and solicitation costs		200,000
Miscellaneous		100,000
Total	US$	8,400,000

ASE Inc. will pay US$4.3 million and ASE Test will pay US$4.1 million of the total estimated fees, costs and expenses listed above.

Treatment of Options

Upon the effectiveness of the scheme: (i) each in-the-money ASE Test option that remains outstanding as of the books closure date (whether vested or unvested as of the effective date of the scheme) will be deemed to have been exercised as of the books closure date by ASE Test on behalf of the option holder through a broker on a cashless basis, and the ASE Test ordinary shares issued upon such mandatory exercise of the option will be acquired by ASE Inc. for the scheme consideration of US$14.78 per ASE Test Nasdaq Share in cash, and as a result the option holder will receive a cash payment equal to the excess of the per share scheme consideration over the per share exercise price of the option, less any interest, fees and charges of the broker; and (ii) each out-of-the-money ASE Test option that remains outstanding as of the books closure date (whether vested or unvested as of the effective date of the scheme) will be cancelled without any payment to the option holder.

Implementation of the Scheme

Application to Court for Sanction. Upon the approval and adoption of the scheme by the requisite majority of unaffiliated ASE Test shareholders, ASE Test will make an application to the court to sanction the scheme.

Implementation Procedure

If the court sanctions the scheme, the order of the court sanctioning the scheme will be lodged with the ACRA, the scheme will become effective and all ASE Test ordinary shares held by ASE Test shareholders (other than ASE Inc. and its subsidiaries) as of the books closure date will be acquired by ASE Inc.

Upon the effectiveness of the scheme, all share certificates representing an interest in ASE Test ordinary shares will cease to have any effect as a document evidencing the title of such shares by operation of Singapore law. Each ASE Test shareholder will be notified of the procedures to submit share certificates to the address of the Share Registrar of ASE Test specified in the notice, and will be required to follow such procedures.

As promptly as practicable after the effective date of the scheme, and in any event within 10 calendar days after the effective date of the scheme, ASE Inc. will deposit with the paying agent cash in an amount equal to the aggregate scheme consideration payable to all ASE Test shareholders (other than ASE Inc. and its subsidiaries) of record as of the books closure date, as payment for all ASE Test ordinary shares held by such shareholders. The paying agent will (i) send to each ASE Test shareholder a check payable to such ASE Test shareholder, or (ii) credit the designated bank account of each ASE Test shareholder with, an amount equal to the aggregate scheme consideration payable with respect to the ASE Test ordinary shares held by such shareholder, net of applicable withholding tax, if any, as payment for the transfer of such shares to ASE Inc. under the scheme. See “The Scheme Implementation Agreement—Scheme Consideration” beginning on page [ · ].

The checks for the scheme consideration will be sent by first class mail to each such ASE Test shareholder’s address in the Register of Members of ASE Test or, in case of joint shareholders, to the address of the shareholder whose name appears first in the Register of Members of ASE Test, in each case, at the sole risk of such shareholder.

After the six-month anniversary of the date the payments for the scheme consideration are disbursed to the ASE Test shareholders (other than ASE Inc. and its subsidiaries), ASE Inc. will have the right to cancel or countermand payment of any check for the payment of the scheme consideration that has not been cashed (or returned uncashed) and is required to deposit such amount in a bank account in the name of ASE Test with a licensed bank in Singapore selected by ASE Test. ASE Test or its successor entity is required to maintain such deposited amount in the bank account until six years after the effective date of the scheme. Prior to such date, ASE Inc. is required to make payments from this bank account of amounts (without interest) payable to any person who satisfies ASE Test or its successor entity that such person is entitled to such amounts under the scheme and (if the scheme consideration is paid by check) the check of which such person is the payee has not been cashed. Following six years after the effective date of the scheme, ASE Inc. will have no further obligation to make any payments under the scheme, and ASE Test or its successor entity will transfer to ASE Inc. the balance of such bank account, including any accrued interest, after the deduction of expenses and any interest, tax or any withholding tax or any other deduction required by applicable law.

You are encouraged to read “The Scheme”, attached to this scheme document as Appendix D, in its entirety for more details regarding the procedures required to receive the scheme consideration.

Closure of Books

Notice of Books Closure. If and after the scheme is approved and adopted by the unaffiliated ASE Test shareholders at the court meeting and the order of the court sanctioning the scheme is obtained, ASE Test will give notice of the books closure date to ASE Test shareholders, for the purpose of determining the ASE Test shareholders entitled to the scheme consideration. The books closure date is tentatively scheduled for [ · ] at 5:00 p.m., Singapore time.

Trading in Shares on NASDAQ and the Taiwan Stock Exchange. Upon the effectiveness of the scheme, ASE Test will become an indirect wholly-owned subsidiary of ASE Inc., and ASE Inc. intends to cause ASE Test to apply for withdrawal of the ASE Test Nasdaq Shares and the ASE Test TDSs from listing on The NASDAQ Global Market and the Taiwan Stock Exchange, respectively.

Settlement and Registration Procedures

After the scheme becomes effective, the following settlement and registration procedures will apply:

(i)

Entitlements to the scheme consideration will be determined on the basis of the ASE Test shareholders (other than ASE Inc. and its subsidiaries) and their holdings of ASE Test ordinary shares appearing on the Register of Members on the books closure date, which is tentatively scheduled on [ · ] at 5:00 p.m., Singapore time.

(ii)

Each ASE Test shareholder is strongly encouraged to take necessary actions to ensure that the ASE Test ordinary shares owned by such shareholder are registered in his or her name, or, if such shareholder is a holder of ASE Test Nasdaq Shares in “street name” through a broker or in the form of ASE Test TDSs, such shares are in accounts in his or her name, by the books closure date, which is tentatively scheduled for [ · ] at 5:00 p.m., Singapore time.

(iii)

On the effective date of the scheme, each existing share certificate representing an interest in ASE Test ordinary shares held by an ASE Test shareholder (other than ASE Inc. and its subsidiaries) will cease to be evidence of title to the ASE Test ordinary shares represented thereby. Within 10 calendar days after the effective date of the scheme, ASE Inc. will make payment of the scheme consideration to each ASE Test shareholder (other than ASE Inc. and its subsidiaries) based on his or her holding of ASE Test ordinary shares as of the books closure date.

Shareholders Outside the United States, the Republic of China or the Republic of Singapore

Shareholders Outside the United States, the Republic of China or the Republic of Singapore. The applicability of the scheme to ASE Test shareholders whose addresses are outside the United States, the Republic of China and the Republic of Singapore, as shown on the Transfer Books and the Register of Members of ASE Test ordinary shares, referred to herein as overseas ASE Test shareholders, may be affected by the laws of the relevant jurisdictions where such persons are located. Accordingly, such ASE Test shareholders should inform themselves about and observe any applicable legal requirements.

It is the responsibility of overseas ASE Test shareholders to satisfy themselves as to the full observance of the laws of the relevant jurisdiction, including the obtaining of any governmental or other consent which may be required and compliance with all required regulatory or legal requirements. Any overseas ASE Test shareholder in any doubt should consult his or her professional advisor in the relevant jurisdiction.

Copies of Scheme Document. ASE Test shareholders, including overseas ASE Test shareholders, may obtain additional copies of this scheme document and any related documents during the normal business hours on any day prior to the date of the court meeting, from 10 West Fifth Street, Nantze Export Processing Zone, Kaohsiung, Taiwan, Republic of China. Alternatively, an overseas ASE Test shareholder may write to ASE Test at 10 West Fifth Street, Nantze Export Processing Zone, Kaohsiung, Taiwan, Republic of China, Attention: Ms. Eileen Sih, to request a copy of this scheme document and any related documents to be mailed to an address in the United States, the Republic of China or the Republic of Singapore by ordinary post at such shareholder’s own risk. Such written requests must be received no later than three business days prior to the date of the court meeting.

It is the responsibility of any overseas ASE Test shareholder who requests a copy of this scheme document and any related documents to satisfy himself or herself as to the full observance of the laws of the relevant jurisdiction in that connection, including the obtaining of any governmental or other consent which may be required and compliance with all necessary formalities or legal requirements. In requesting a copy of this scheme document and any related documents, the overseas ASE Test shareholder represents and warrants to ASE Inc. and ASE Test that he or she is in full observance of the laws of the relevant jurisdiction in that connection, and that he or she is in full compliance with all necessary formalities or legal requirements.

Notice. ASE Inc. and ASE Test each reserves the right to notify any or all ASE Test shareholders with a registered address outside the United States, the Republic of China or the Republic of Singapore of any matter, including the fact that the scheme has been proposed, by announcement through public filings with the SEC, announcements on the Taiwan Stock Exchange and paid advertisement in a daily newspaper published and circulated in the United States, the Republic of China and in the Republic of Singapore, and such notice will be deemed to have been sufficiently given notwithstanding any failure by any shareholder to receive or see such filing or announcements. As long as ASE Test Nasdaq Shares or ASE Test TDSs remain listed on The Nasdaq Global Market and the Taiwan Stock Exchange, as applicable, ASE Test will continue to be subject to the applicable reporting requirements under the Exchange Act and the rules of the Taiwan Stock Exchange.

United States Federal Income Tax Consequences

This disclosure is limited to the U.S. federal income tax issues addressed below. Additional issues may exist that are not addressed in this disclosure and that could affect the U.S. federal income tax treatment

of the disposal of ASE Test ordinary shares pursuant to the scheme. Holders of ASE Test ordinary shares should seek their own advice based on their particular circumstances from an independent tax advisor.

The following is a discussion of the material U.S. federal income tax consequences of disposal of ASE Test Nasdaq Shares or ASE Test TDSs, referred to herein as ASE Test shares, pursuant to the scheme by the U.S. Holders (as defined below). This discussion does not address U.S. state, local and non-U.S. tax consequences. The discussion applies only to U.S. Holders who hold ASE Test shares as capital assets for U.S. federal income tax purposes, and it does not address special classes of holders, such as:

certain financial institutions;

insurance companies;

dealers and traders in securities or foreign currencies;

persons holding shares as part of a hedge, straddle, conversion or other integrated transaction;

persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;

partnerships or other entities classified as partnerships for U.S. federal income tax purposes;

persons liable for the alternative minimum tax;

tax-exempt organizations;

persons holding shares that own or are deemed to own 10% or more of our voting stock; or

persons who acquired ASE Test ordinary shares pursuant to the exercise of any employee stock option or otherwise as compensation.

This discussion is based on the United States Internal Revenue Code of 1986, as amended, administrative pronouncements, judicial decisions and final, temporary and proposed United States Treasury regulations, all as of the date hereof. These laws are subject to change, possibly on a retroactive basis. Prospective investors should consult their own tax advisors concerning the U.S. federal, state, local and non-U.S. tax consequences in their particular circumstances.

As used herein, a “U.S. Holder” is a beneficial owner of ASE Test shares that is, for United States federal income tax purposes: (i) a citizen or resident of the United States; (ii) a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States or any political subdivision thereof; or (iii) an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

This discussion assumes that ASE Test is not, and will not become, a passive foreign investment company, referred to herein as a PFIC, as discussed below.

Sale and Other Disposition of Shares

A U.S. Holder will recognize capital gain or loss on the disposal of ASE Test shares pursuant to the scheme, which will be long-term capital gain or loss if such holder has held such shares for more than one year. The amount of the U.S. Holder’s gain or loss will be equal to the difference between the scheme consideration received by such holder (as determined in U.S. dollars) and such holder’s tax basis in ASE Test shares (as determined in U.S. dollars). Any gain or loss will generally be U.S. source gain or loss for foreign tax credit purposes.

Passive Foreign Investment Company Rules

ASE Test does not expect to be a PFIC for U.S. federal income tax purposes for its 2007 taxable year. However, PFIC status depends upon the composition of a company’s income and assets and the market value of its assets from time to time. Because ASE Test has significant cash and other passive assets, including the common shares of ASE Inc. it currently holds, and because ASE Test’s PFIC status may be affected by the value of its shares (from time to time), there can be no assurance that ASE Test will not be considered a PFIC for its 2007 taxable year.

If ASE Test were treated as a PFIC for any taxable year during a U.S. Holder’s holding period for ASE Test shares, gain recognized by the U.S. Holder on a sale or other disposition of a share would be allocated ratably over such holder’s holding period for the share. The amount allocated to the taxable year of the sale or other exchange and to any year before ASE Test became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, and an interest charge would be imposed on the amount allocated to such taxable year.

If a U.S. Holder holds ASE Test shares during any year in which ASE Test is a PFIC, such holder must file an Internal Revenue Service Form 8621 with the Unites States Internal Revenue Service.

Information Reporting and Backup Withholding

Payments of the scheme consideration may be subject to information reporting and to backup withholding unless the U.S. Holder is a corporation or other exempt recipient or, in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that no loss of exemption from backup withholding has occurred. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against such holder’s U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is furnished to the United States Internal Revenue Service.

Republic of China Income Tax Consequences

For Taiwan individual shareholders, the gain resulting from the disposition of the ASE Test ordinary shares will be free from personal income tax in Taiwan. For Taiwan corporate shareholders, the gain resulting from the disposition of the ASE Test ordinary shares will be taxed at the current income tax rate of 25%.

Appraisal Rights

Once the scheme is approved and adopted by the unaffiliated ASE Test shareholders, sanctioned by the court and becomes effective, it will be binding on all ASE Test shareholders. Dissenting ASE Test shareholders may file an objection with the court against the granting of the court sanction, but no appraisal rights are available to dissenting ASE Test shareholders in connection with a scheme of arrangement effected under Singapore law.

Regulatory Matters

Taiwan. ASE Inc. is required to apply for the approval of the ROC IC for its proposed acquisition of ASE Test ordinary shares by way of the scheme, as the proposed acquisition constitutes an increase in ASE Inc.’s investment in ASE Test. ASE Inc. applied for the ROC IC approval on October 22, 2007. The ROC IC approved the application on December 26, 2007. However, the ROC IC approval will be automatically terminated if the scheme fails to be approved by the requisite majority of the unaffiliated ASE Test shareholders and sanctioned by the court within six months after the ROC IC granted its approval.

In addition, because the proposed acquisition of ASE Test ordinary shares by way of the scheme involves an acquisition of more than one-third of the total outstanding ASE Test ordinary shares and meets certain specified thresholds (including those relating to market share or revenue) under applicable laws and regulations, ASE Inc. is required to file a merger report with the ROC FTC and obtain the ROC FTC’s approval for the scheme. ASE Inc. filed the merger report with the ROC FTC on October 26, 2007 and obtained the ROC FTC’s approval dated November 6, 2007.

Singapore. Pursuant to the Companies Act, Chapter 50 of Singapore, the court has directed that the court meeting be convened for the purpose of approving and adopting the scheme. If the requisite majority of the unaffiliated ASE Test shareholders votes to approve and adopt the scheme at the court meeting, an application will be made to the court by ASE Test to sanction the scheme.

In response to an application made by ASE Inc. seeking an exemption by the SIC from the application of all the provisions of the Singapore Code or, alternatively, the SIC’s confirmation that specified provisions of the Singapore Code do not apply to the scheme, the SIC has in a ruling dated October 17, 2007 confirmed that while it does not exempt the application of all the provisions of the Singapore Code, Rules 14, 15, 16, 17, 20.1, 21, 22, 28, 29 and 33.2 and Note 1(b) to Rule 19 of the Singapore Code will not apply to the scheme, subject to the following conditions: (i) ASE Test shareholders acting in concert with ASE Inc. abstain from voting on the scheme; (ii) directors of ASE Test who are also directors of ASE Inc. abstain from making a recommendation on the scheme to ASE Test shareholders; (iii) ASE Test appoint an independent financial advisor to advise ASE Test shareholders on the scheme; and (iv) ASE Inc. consult with the SIC prior to invoking any of the conditions to the scheme. ASE Inc. and ASE Test believe that all of the conditions for the exemptions have been or are currently expected to be met. See “The Court Meeting—Persons Entitled to Vote; Vote Required; Quorum” beginning on page [ · ]; “—ASE Test’s Reasons for the Scheme; Recommendation of ASE Test’s Board of Directors” beginning on page [ · ]; “—Opinion of ANZ Singapore” beginning on page [ · ]; and “—Recommendation of ASE Test’s Independent Directors” beginning on page [ · ].

General. It is possible that any of the governmental entities with which filings are made may seek, as conditions for granting approval of the scheme, various regulatory concessions. Pursuant to the scheme implementation agreement, the parties have agreed to use their best endeavors to obtain any required regulatory approvals, subject to certain exceptions. There can be no assurance that ASE Inc. or ASE Test will be able to satisfy or comply with such conditions, compliance or non-compliance will not have material and adverse consequences on ASE Inc. or ASE Test, or the required regulatory approvals will be obtained within the time frame contemplated by the parties or on terms that will be satisfactory to the parties. See “The Scheme Implementation Agreement—Best Endeavors” on page [ · ].

THE SCHEME IMPLEMENTATION AGREEMENT

The following is a summary of the material terms of the scheme implementation agreement, which is qualified in its entirety by the scheme implementation agreement. A copy of the scheme implementation agreement is attached to this scheme document as Appendix A and is incorporated herein by reference. This summary may not contain all of the information that is important to you. ASE Test shareholders are urged to read the scheme implementation agreement in its entirety.

Structure of the Scheme

Pursuant to the scheme implementation agreement, ASE Inc. and ASE Test have agreed that the privatization of ASE Test will be effected by way of the scheme, which will involve, among other things, the transfer to ASE Inc., on the effective date of the scheme, of: (i) all ASE Test ordinary shares held by ASE Test shareholders (other than ASE Inc. and its subsidiaries); and (ii) all ASE Test ordinary shares issued pursuant to the treatment of options (described below) as of the effective date of the scheme. Following the effectiveness of the scheme, ASE Test will become an indirect wholly-owned subsidiary of ASE Inc.

The “books closure date” is the date on which the Register of Transfer and the Register of Members of ASE Test will be closed for the purpose of determining which ASE Test shareholders (excluding ASE Inc. and its subsidiaries) are entitled to receive the consideration pursuant to the scheme. See “Special Factors Regarding the Scheme—Closure of Books” on page [ · ].

Effective Date of the Scheme

Subject to the fulfillment of all conditions to the scheme set forth in the scheme implementation agreement, the scheme will become effective on the date a copy of the court order sanctioning the scheme is lodged with the ACRA, or such other date as ASE Inc. and ASE Test may agree in writing. The date the scheme becomes effective is referred to herein as the effective date.

Scheme Consideration

Upon the effectiveness of the scheme, ASE Test shareholders (other than ASE Inc. and its subsidiaries) of record as of the books closure date will be entitled to receive the following consideration:

(a)

for each ASE Test Nasdaq Share held by such ASE Test shareholder, US$14.78 in cash; and

(b)

for each ASE Test TDS held by such ASE Test shareholder, the NT$ equivalent of US$0.185 in cash determined as of the books closure date based on the noon buying rate as of the books closure date, referred to as the prevailing exchange rate elsewhere in this scheme document.

The “noon buying rate” as of any date of determination is the rate published by the Federal Reserve Bank of New York for spot purchases of NT$ as of 12:00 noon on the New York business day immediately preceding such date of determination.

The above-described consideration will be reduced to the extent any dividend or distribution with respect to ASE Test ordinary shares is paid or made to ASE Test shareholders on or prior to the effective date. In addition, the aggregate cash payment payable to any ASE Test shareholders pursuant to the scheme will be rounded down to the nearest whole cent, if applicable.

Treatment of Options

Upon the effectiveness of the scheme, each ASE Test option that remains outstanding as of the books closure date (whether vested or unvested as of the effective date of the scheme) will be treated as follows, referred to herein as the treatment of options:

For each in-the-money ASE Test option, the existing terms of each such option will be amended to permit the option to be, and each such option will be, deemed to have been exercised by ASE Test as of the books closure date on behalf of the option holder on a cashless basis through a broker, and the broker will

advance the full cash exercise price of such option to ASE Test. The ASE Test ordinary shares issued upon such mandatory exercise of each in-the-money ASE Test option will be acquired by ASE Inc. for the scheme consideration of US$14.78 per ASE Test Nasdaq Share in cash, and as a result the option holder will receive a cash payment equal to (i) the number of ASE Test ordinary shares issued pursuant to such mandatory exercise multiplied by the per share scheme consideration, less (ii) the total exercise price of such option advanced by the broker plus any interest due on such amount and any fees and charges of the broker.

For each out-of-the-money ASE Test option, the option will be cancelled on the effective date of the scheme without any payment to the option holder.

Pursuant to the scheme implementation agreement, ASE Inc. and ASE Test have agreed to take steps to implement the treatment of options. In particular, ASE Inc. has agreed to use its best efforts to obtain all requisite approvals and take all other necessary actions to implement and give effect to the treatment of options. ASE Test has agreed that it will, to the extent permitted by the provisions of the applicable ASE Test options plans, cancel all ASE Test options which remain outstanding after the effective date of the scheme, and take such steps as may be necessary to give effect to the treatment of options.

Best Endeavors

Each of ASE Test and ASE Inc. has agreed to use its best endeavors to procure the fulfillment of each condition to the scheme that is within its control or influence and promptly notify the other party of any event or circumstance of which it becomes aware and which would be likely to have a significant impact on the fulfillment of conditions to the scheme.

If an appeal to the court’s decision is made by ASE Test, ASE Inc. will provide all reasonable assistance as ASE Test and its advisors may reasonably request for the purposes of the appeal.

Non-Solicitation; Fiduciary-Out

ASE Test has agreed that it will not, and will not authorize or permit any of its independent directors to, directly or indirectly, withdraw or modify in a manner adverse to ASE Inc. the recommendation of the board of directors of ASE Test in favor of the scheme (or take any action or make any public statement inconsistent with such recommendation) or approve or recommend an alternative acquisition proposal.

Notwithstanding the above or any other provision of the scheme implementation agreement, neither ASE Inc. nor ASE Test nor any of their respective directors will be obligated to take any action (or refrain from taking any action) if, and only to the extent that, a majority of the independent directors of ASE Inc. or ASE Test, respectively, conclude in good faith that taking such action (or refraining from taking such action) would constitute a breach of fiduciary duties on the part of the directors of ASE Inc. to the shareholders of ASE Inc. or of the directors of ASE Test to ASE Test shareholders, respectively.

Transactions in ASE Test Shares

There has not been any transaction in ASE Test ordinary shares during the past 60 days by ASE Inc., ASE Test, or any of their respective directors, executive officers, associates or majority-owned subsidiaries. In addition, neither ASE Test nor ASE Inc. has purchased any ASE Test ordinary shares during the past two years.

Transactions with Affiliates

Except as disclosed below, neither ASE Test nor any of its subsidiaries has entered into any material contracts with any interested persons (other than those entered into in the ordinary course of business) during the period commencing three years before September 4, 2007 and ending on the latest practicable date.

ASE Inc. and ASE Test, Inc., a 99.99%-owned subsidiary of ASE Test that is incorporated in Taiwan, referred to herein as ASE Test Taiwan, from time to time jointly market turnkey services provided at their respective Taiwan facilities. ASE Test Taiwan has historically charged ASE Inc. fees for the testing of semiconductors packaged for a small number of customers that prefer to be billed through ASE Inc. for testing services performed by ASE Test Taiwan. These fees amounted to US$16.8 million, US$44.6 million, US$45.1 million and US$22.4 million in 2004, 2005, 2006 and for the nine months ended September 30, 2007, respectively.

ASE Electronics (M) Sdn. Bhd., a wholly-owned subsidiary of ASE Test that is incorporated in Malaysia, referred to herein as ASE Test Malaysia, has historically purchased a portion of the raw materials used in its packaging operations, principally leadframes and substrates, from ASE Inc. Such purchases amounted to US$2.7 million, US$5.4 million and US$2.2 million in 2004, 2005 and 2006, respectively. In addition, ASE Test Malaysia also purchased raw material and substrates from ASE Electronic Inc. after it was spun off from ASE Inc. on August 1, 2006. Such purchase amounted to US$1.0 million and US$2.5 million in 2006 and for the nine months ended September 30, 2007, respectively.

ASE Inc. has historically shared its research and development relating to packaging with ASE Test Malaysia at no cost. While ASE Inc. intends to continue such arrangements in the future, if ASE Inc. were to discontinue such arrangements, ASE Test Malaysia would have to develop the capability for, and bear the cost of, research and development relating to packaging. The approximate dollar amount for such arrangements for each of

the past three years is less than one percent of ASE Test’s consolidated revenues for each such year in which the arrangement took place.

ASE Inc. has in the past guaranteed some of ASE Test’s borrowings and may from time to time provide similar guarantees in the future. From time to time, some of ASE Test’s directors have guaranteed certain of ASE Test’s borrowings. ASE Inc. has historically guaranteed the promissory notes of many of its subsidiaries and affiliates. As of December 31, 2004, 2005 and 2006 and as of September 30, 2007, ASE Inc. had endorsed and guaranteed an aggregate amount of US$358.6 million, US$420.6 million, US$380.8 million and US$304.2 million of the outstanding promissory notes of its subsidiaries, respectively.

ASE Test engages ASE (U.S.) Inc., as a sales agent. In 2004, 2005 and 2006 and for the nine months ended September 30, 2007, ASE Test paid US$ 3.3 million, US$7.7 million, US$5.0 million and US$3.6 million, respectively, in fees and service charges to ASE (U.S.) Inc.

ASE Test currently uses most floors of space owned by ASE Test Taiwan in several buildings in the Nantze Export Processing Zone. The space consists of approximately 1,025,000 square feet and houses ASE Test’s operations in Kaohsiung, Taiwan. The approximate dollar amount for such arrangements for each of the past three years is less than one percent of ASE Test’s consolidated revenues for each such year in which the arrangement took place.

ASE Test currently leases a small portion of its production facilities in Kaohsiung and Chung Li, Taiwan from ASE Inc. ASE Test also leases a small portion of its production facilities in Kaohsiung, Taiwan, to ASE Inc. The approximate dollar amount for such arrangements for each of the past three years is less than one percent of ASE Test’s consolidated revenues for each such year in which the arrangement took place.

ASE Inc. constructed a new building in Kaohsiung, Taiwan, with Hung Ching Development & Construction Co. Ltd., a company incorporated in Taiwan and of which ASE Inc. owns approximately 26.2% of outstanding shares, referred to herein as Hung Ching. The new building was completed in July 2004 and has approximately 1,172,000 square feet of floor space. ASE Inc. and ASE Test Taiwan purchased Hung Ching’s interest in the development in January 2005. ASE Inc. owns the first eight floors of the building with floor space of approximately 940,000 square feet and ASE Test Taiwan owns the remaining two floors with floor space of approximately 232,000 square feet. ASE Inc. uses its floor space to house part of its operations in Kaohsiung. The total cost to ASE Inc. of the construction project was approximately NT$1,329.2 million. In May 2005, ASE Inc. completed the construction of two new buildings, with floor space of approximately 1,313,000 square feet, in Chung Li, Taiwan, with Hung Ching. On May 23, 2006, ASE Inc. purchased from Hung Ching two new buildings in Chung Li, Taiwan, that ASE Inc. built with Hung Ching for NT$1,311.4 million (US$40.2 million).

For more information regarding affiliate transactions involving ASE Inc. and ASE Test and their respective affiliates, please refer to the annual reports on Form 20-F filed by ASE Inc. and ASE Test with the SEC both on June 25, 2007, as amended.

(1)	The loss in 2005 was caused by fire damage to ASE Inc. and its subsidiaries’ production line and facilities in Chung Li, Taiwan, on May 1, 2005.

In October 2005, ASE Test disposed of its camera module assembly operations in Malaysia. Such operations were formerly classified as part of its packaging operations.

Significant Accounting Policies and Changes in Accounting Policies

ASE Inc. prepares its consolidated financial statements in accordance with ROC GAAP, with a reconciliation to U.S. GAAP. Except as disclosed below and in this scheme document, ASE Inc. has applied the same accounting policies in preparing the consolidated financial statements for the fiscal years ended December 31, 2004, 2005 and 2006.

On and with effect from January 1, 2006, ASE Inc. adopted the following accounting policies:

The newly released ROC SFAS No. 34, “Financial Instruments: Recognition and Measurement” and No. 36, “Financial Instruments: Disclosure and Presentation”: ASE Inc. had categorized its financial assets and liabilities upon the initial adoption of the newly released ROC SFAS No. 34 and No. 36. The adjustments made to the carrying amounts of the financial instruments categorized as financial assets or liabilities at fair value through profit or loss were included in the cumulative effect of changes in accounting principles; on the other hand, the adjustments made to the carrying amounts of those categorized as available-for-sale financial assets were recognized as adjustments to shareholders’ equity. Deferred exchange losses for cash-flow hedges were reclassified as adjustments to shareholders’ equity; and

The newly revised ROC SFAS No. 5, “Long-term Investments under Equity Method” and No. 25, “Business Combinations” : ASE Inc. adopted the newly revised ROC SFAS No. 5 and ROC SFAS No. 25, which prescribe that investment premiums, representing goodwill, be ceased from amortization and be assessed for impairment at least on an annual basis.

Upon the adoption of ROC SFAS No. 34, certain accounts in the audited consolidated financial statements of ASE Inc. and its subsidiaries as of December 31, 2005 and for the years ended December 31, 2004 and 2005 were reclassified to conform to the consolidated financial statements as of and for the year ended December 31, 2006. The previous issued consolidated financial statements as of December 31, 2005 and for the years ended December 31, 2004 and 2005 were not required to be restated.

Appendix B

September 4, 2007

Special Committee of the Board of Directors

ASE Test Limited

One Marina Boulevard, #28-00

Singapore

Members of Special Committee of the Board of Directors:

We understand that ASE Test Limited (the “Company” or “ASE Test”) intends to enter into a transaction (the “Proposed Transaction”) with Advanced Semiconductor Engineering, Inc. (“ASE Inc.”) pursuant to which ASE Test is to be privatized by way of a scheme of arrangement (“Scheme”) under Section 210 of the Companies Act, Chapter 50 of Singapore. We further understand that, p ursuant to the Proposed Transaction, ASE Inc. will acquire on the date on which the Scheme becomes effective all the ordinary shares of ASE Test (“ ASE Test Shares” ) then outstanding other than the ASE Test Sh ares held by ASE Inc. and its subsidiaries in exchange for (i) US $14.78 in cash (the “ Per-Share Scheme Consideration” ) for each ASE Test Share listed and quoted on The Nasdaq Stock Market, Inc. and (ii) the NT$ equivalent of US$0.18475 in cash (the “ Per-TD S Scheme Consideration” , and together with the Per-Share Scheme Consideration, the “ Scheme Consideration” ) for each Taiwan depositary share of ASE Test, representing ASE Test Shares, listed and quoted on the Taiwan Stock Exchange. The terms and conditions of the Proposed Transaction are set forth in more detail in the Scheme Implementation Agreement to be executed as of September 4, 2007 (the “Agreement”).

We have been requested by the Special Committee of the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the holders of ASE Test Shares other than ASE Inc. and its affiliates (which affiliates include, without limitation, the directors and executive officers of ASE Inc.) ( the “ Unaffili ated ASE Test Shareholders” ) of the Scheme Consideration to be received by the Unaffiliated ASE Test Shareholders in the Proposed Transaction. We have not been requested to opine as to, and our opinion does not in any manner address, the Company’s underlying business decision to proceed with or effect the Proposed Transaction.

In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and correspondences between ASE Inc. and the Company, including the specific terms of the Proposed Transaction, (2) publicly available information concerning the Company that we believe to be relevant to our analysis, including the Annual Report on Form 20-F for the fiscal year ended December 31, 2006 and un-audited financial results of the Company for the first half ended June 30, 2007, (3) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by the Company, including monthly management accounts for July 2007 and additional management accounts, if any, and financial

projections of the Company for 2007 prepared by management of the Company, (4) a trading history of the Company’s common stock for the last twelve months and a comparison of that trading history with those of other companies that we deemed relevant, (5) a comparison of the historical financial results and present financial condition of the Company with those of other companies that we deemed relevant, (6) published estimates of independent research analysts with respect to the future fi nancial performance of the Company, and (7) a comparison of the financial terms of the Proposed Transaction with the financial terms of certain other transactions that we deemed relevant. In addition, we have had discussions with the management of the Company concerning its business, operations, assets, liabilities, financial condition and prospects and have undertaken such other studies, analyses and investigations as we deemed appropriate.

In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without assuming any responsibility for independent verification of such information and have further relied upon the assurances of management of the Company that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of the Company, upon advice of the Company we have assumed that such projections have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance of the Company and that the Company will perform substantially in accordance with such projections. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company. In addition, you have not authorized us to solicit, and we have not solicited, any indications of interest from any third party with respect to the purchase of all or a part of the Company’s business. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter.

Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the Scheme Consideration to be received by the Unaffiliated ASE Test Shareholders in the Proposed Transaction is fair to such Unaffiliated ASE Test Shareholders.

We have acted as financial advisor to the Special Committee of the Board of Directors of the Company in connection with the Proposed Transaction and will receive a fee for our services a material portion of which is contingent upon the consummation of the Proposed Transaction. In addition, the Company has agreed to indemnify us for certain liabilities that may arise out of the rendering of this opinion. We also have performed various investment banking services for the Company in the past and have received customary fees for such services. In the ordinary course of our business, we actively trade in the equity securities of the Company for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities.

This opinion is for the use and benefit of the Special Committee of the Board of Directors of the Company and, accordingly, the Unaffiliated ASE Test Shareholders and is rendered to the Special Committee of the Board of Directors in connection with its consideration of the Proposed Transaction ; provided, that a copy of this opinion, and any bring-down opinion (if any) , may be included in its entirety in the S cheme document to be dispatched to the Unaffiliated ASE Test

Shareholders and in any filings that the Company is required to make with the U.S. Securities and Exchange Commission (or any other filings to be specifically agreed by us) in connection with the Prop osed Transaction . This opinion is not intended to be and does not constitute a recommendation to any Unaffiliated ASE Test Shareholder of the Company as to how such Unaffiliated ASE Test Shareholder should vote with respect to whether to accept the consideration to be offered to the Unaffiliated ASE Test Shareholders in connection with the Proposed Transaction.

	Very truly yours,


	LEHMAN BROTHERS

Years Ended December 31, 2004, 2005 and 2006 and

Report of Independent Registered

Public Accounting Firm

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

ASE Test Limited

We have audited the accompanying consolidated balance sheets of ASE Test Limited and subsidiaries (collectively the “Company”) as of December 31, 2005 and 2006, and the related consolidated statements of income, changes in shareholders’ equity and cash flows for each of the three years ended December 31, 2006, expressed in U.S. dollars. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the Rules Governing the Audit of Financial Statements by Certified Public Accountants, auditing standards generally accepted in the Republic of China and the Standards of the Public Company Accounting Oversight Board (United States). Those rules and standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2005 and 2006, and the consolidated results of their operations and their cash flows for each of the three years ended December 31, 2006, in conformity with the requirements of the Business Accounting Law and Guidelines Governing Business Accounting relevant to financial accounting standards, and accounting principles generally accepted in the Republic of China.

F-1

As discussed in Note 21 to the consolidated financial statements, the Company incurred fire damage to its production line in Chung Li, Taiwan on May 1, 2005. The Company recognized an estimated loss of $52,014 thousand for the damage to its machinery and equipment, less $790 thousand of insurance receivable in 2005. The Company reached final settlement with the insurers in June 2006 with regards to the fire damage referred to above. The final settlement amount of $27,289 thousand, less the $790 thousand recorded in 2005, was recorded as a gain in 2006. The Company also reversed $5,641 thousand of previously recorded impairment charges on these fire-damaged machinery and equipment due to an increase in the estimated service potential of the assets.

As discussed in Note 3 to the consolidated financial statements, the Company adopted the Republic of China Statement of Financial Accounting Standards No. 34, “Financial Instruments: Recognition and Measurement”, No. 36, “Financial Instruments ： Disclosure and Presentation” and other revised Statements on January 1, 2006.

Accounting principles generally accepted in the Republic of China differ in certain significant respects from accounting principles generally accepted in the United States of America. Information relating to the nature and effect of such differences is presented in Note 24 to the consolidated financial statements.

1. ORGANIZATION AND OPERATION

Overview

ASE Test Limited (“ASE Test” or the “Company”) is a Singapore holding company which, through an exchange of its shares with its parent company, Advanced Semiconductor Engineering, Inc. (“ASE Inc.”), and other individuals, acquired substantially all of the shares of ASE Test, Inc. in May 1996. The exchange was accounted for as a reorganization of companies under common control. Since June 1996, the Company’s shares have been traded on the NASDAQ Global Market in the United States under the symbol “ASTSF”.

J & R Holding Limited, a shareholder of the Company, offered 6,000,000 and 5,000,000 shares of the Company’s common stock in December 1997 and February 1999, respectively, in the form of Taiwan Depositary Receipts (“TDRs”). The TDRs are traded on the Taiwan Stock Exchange under the symbol “9101” and each TDR represents 0.0125 share of the Company’s stock.

Set forth below is a brief overview of the Company’s organization structure.

The Company has four direct subsidiaries:

a. ASE Test, Inc. (incorporated in the Republic of China (“ROC”) in December 1987), which is engaged in the testing of semiconductors.

b. ASE Holdings (Singapore) Pte Ltd. (incorporated in Singapore in December 1994), which holds shares in ASE Test group companies;

c. ASE Test Holdings, Limited (“ASE Test Holdings”) (incorporated in Cayman Islands in April 1999), which holds shares in ASE Test group companies; and

d. ASE Test Finance Limited (“ASE Test Finance”) (incorporated in Mauritius in June 1999), which is engaged in financing activities.

ASE Holdings (Singapore) Pte Ltd. has a wholly-owned subsidiary, ASE Electronics (M) Sdn. Bhd. (“ASE Test Malaysia”) (incorporated in Malaysia in February 1991), which is engaged in the packaging and testing of semiconductors. ASE Test Malaysia disposed of its camera module operations on October 3, 2005 (See Note 23).

ASE Test Holdings has a wholly-owned subsidiary, ISE Labs, Inc. (“ISE Labs”) (incorporated in California, United States in November 1983). ISE Labs and its wholly-owned subsidiaries, ISE Labs Hong Kong Limited, which was dissolved in 2005, ASE Singapore Pte Ltd., ISE Technology, Inc. and Digital Testing Services Inc., are engaged in the front-end engineering testing and final testing of semiconductors.

As of December 31, 2005 and 2006, the Company had approximately 5,600 and 5,300 employees, respectively.

2. SIGNIFICANT ACCOUNTING POLICIES

The accompanying consolidated financial statements have been prepared in conformity with the Business Accounting Law, Guidelines Governing Business Accounting, and accounting principles generally accepted in the Republic of China (“ROC GAAP”). Under these law, guidelines and principles, the Company should reasonably estimate the amounts of allowances for doubtful accounts, allowance for sales discounts, inventory obsolescence, depreciation of property, plant, and equipment, loss on impairment of assets, pension costs, gain (loss) on valuation of financial instruments and valuation allowance for deferred income tax assets. Actual results may differ from these estimates. Significant accounting policies are summarized as follows:

Basis of Presentation

The Company prepares its consolidated financial statements using the aforementioned law, guidelines and principles with a reconciliation to accounting principles generally accepted in the United States of America (“U.S. GAAP”) (See Note 24) to be consistent with the basis of presentation of the consolidated financial statements of ASE Inc. The accompanying consolidated balance sheets are presented as of December 31, 2005 and 2006 and the accompanying consolidated statements of income, changes in shareholders’ equity and cash flows are presented for the three years ended December 31, 2004, 2005 and 2006.

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and all of the aforementioned subsidiaries.

All significant intercompany accounts and transactions have been eliminated.

Current and Noncurrent Assets and Liabilities

Current assets include cash, financial assets held for trading purposes and assets expected to be converted to cash, sold or consumed within one year from the balance sheet date. Current liabilities are obligations incurred for trading purposes and obligations expected to be settled within one year from the balance sheet date. Assets and liabilities that are not classified as current are noncurrent assets and liabilities, respectively.

Financial Assets / Liabilities at Fair Value Through Profit or Loss

Financial instruments at fair value through profit or loss consist of financial assets or financial liabilities held or incurred for trading purposes. These financial instruments are initially recognized at fair value, with associated transaction costs expensed as incurred. The financial instruments are subsequently remeasured at fair value, and changes in fair value are recognized in current income (loss). A regular way purchase or sale of financial assets is recognized and derecognized using settlement date accounting.

Derivatives which do not qualify for hedge accounting are recorded as financial assets or liabilities at fair value through profit or loss. Fair values of derivatives with no active market are estimated using valuation techniques.

Available-for-Sale Financial Assets

Available-for-sale financial assets are initially recognized at fair value plus transaction costs that are directly attributable to the acquisition. Changes in fair value of financial assets are reported in a separate component of shareholders’ equity. The corresponding accumulated gains or losses are recognized in earnings when the financial asset is derecognized from the balance sheet. A regular way purchase or sale of financial assets is accounted for using settlement date accounting.

F-11

Fair values of beneficiary certificates of open-end mutual funds and publicly traded stocks are determined using the net asset value and closing-price at the balance sheet date , respectively.

If certain objective evidence indicates that such available-for-sale financial asset is impaired, a loss is recognized currently. If, in a subsequent period, the amount of the impairment loss decreases, for equity securities, the previously recognized impairment loss is reversed to the extent of the decrease and recorded as an adjustment to shareholders’ equity.

Revenue Recognition, Accounts Receivable and Allowances for Doubtful Accounts and Sales Allowances

Revenues from semiconductor packaging services are recognized upon shipment. Revenues from semiconductor testing services are recognized upon completion of the services or shipment. The Company does not take ownership of: (i) bare semiconductor wafers received from customers that the Company packages into finished semiconductors, and (ii) packaged semiconductors received from customers that the Company tests as to whether they meet certain performance specifications. The title and risk of loss remain with the customer for those bare semiconductors and/or packaged semiconductors. Accordingly, costs of customer-supplied semiconductor materials are not included in the accompanying consolidated financial statements. Other criteria the Company uses to determine when to recognize revenue are: (i) existence of persuasive evidence of an arrangement, (ii) the selling price is fixed or determinable and (iii) collectibility is reasonably assured.

Revenues are determined using the fair value taking into account related sales discounts agreed to by the Company and customers. Since the receivables from sales are collectible within one year and such transactions are frequent, the fair value of receivables is equivalent to the nominal amount of cash received.

Allowance for doubtful accounts is provided based on an evaluation of the collectibility of receivables. The Company determines the amount of allowance for doubtful accounts by examining the aging analysis of the outstanding accounts receivable and current trends in the credit quality of its customers. An appropriate sales allowance, based on historical experience, is also recognized in the same period the sale is recognized.

Accounts Receivable Securitization

Accounts receivable securitization is the transfer of a designated pool of accounts receivable to a bank, which in turn issues beneficial securities or asset-backed securities based on the accounts receivable. Under ROC Statement of Financial Accounting Standards (“ROC SFAS”) No. 33, “Accounting for Transfers of Financial Assets and Extinguishments of Liabilities”, such transfer of financial assets in which the transferor surrenders control over those assets is accounted for as a sale to the extent that consideration other than beneficial interests in the transferred assets is received in exchange. The difference between the book value of accounts receivable and total proceeds received is recorded as a gain or loss on disposal of financial assets.

Inventories

Inventories including raw materials (materials received from customers for processing, mainly semiconductor wafers are excluded from inventories as title and risk of loss remain with the customers), supplies and spare parts, finished goods and work in process are stated at the lower of cost or market value. Market value represents net realizable value for finished goods and work in process, and replacement cost for raw materials, supplies and spare parts.

Raw materials, supplies and spare parts are recorded at moving average cost or weighted average cost; others are recorded at standard cost and adjusted to the approximate weighted average cost at the balance sheet date. Estimated losses on scrap and slow-moving items are recognized and included in the allowance for losses.

F-12

Equity Method Investments

Investments in companies of which the Company owns at least 20% of the outstanding voting shares or where the Company exercises significant influence over the investee company’s operating and financial policy decisions are accounted for using the equity method. Prior to January 1, 2006, the difference, if any, between the cost of investment and the Company’s proportionate equity in the fair value of the net assets of the investees at the time of investments or at the time the equity method of accounting is first applied to a particular investment, was amortized on the straight-line method over 10 years. Effective January 1, 2006, pursuant to the revised ROC SFAS No. 5, “Long-term Investments under Equity Method” (“ROC SFAS No. 5”), the cost of an investment shall be analyzed and the difference between the cost of investment and the fair value of identifiable net assets acquired, representing goodwill, shall not be amortized and instead shall be tested for impairment annually. The accounting treatment for the investment premiums acquired before January 1, 2006 is the same as that for goodwill which is no longer being amortized. When an indication of impairment is identified, the carrying amount of the investment is reduced, with the related impairment loss recognized in earnings.

Financial Assets Carried at Cost

Investments that do not have a quoted market price in an active market and whose fair value cannot be reliably measured are carried at their original cost, such as non-publicly traded stocks. The costs of financial assets sold are determined using the weighted-average method. If there is objective evidence which indicates that a financial asset is impaired, a loss is recognized. A subsequent reversal of such impairment loss is not allowed.

Property, Plant and Equipment

Property, plant and equipment, except for machinery and equipment under operating leases, are stated at cost less accumulated depreciation and accumulated impairment. Machinery and equipment held under capital leases are recorded as an asset and an obligation at an amount equal to the lower of: (i) present value at the beginning of the lease term of the minimum lease payments during the lease term (including the payment called for under any bargain purchase option); or (ii) fair value of the leased machinery and equipment at the inception of the lease. Machinery in transit, construction in progress and prepayments under construction are stated at cost. These include the cost of machinery, construction, down payments and other direct costs plus interest charges attributable to the borrowings used to finance the acquisitions of these assets. Major overhauls and improvements are capitalized, while maintenance and repairs are expensed as incurred.

Depreciation is computed using the straight-line method over estimated service lives, which range as follows: buildings and improvements, 2 to 40 years; machinery and equipment, 2 to 6 years; furniture and fixtures, 2 to 8 years; and leased assets, 2 to 6 years. Leasehold improvements and improvements on building and business flats are amortized on a straight-line basis over the shorter of the useful life of the improvements or the lease term of the building. In the event that an asset depreciated to its residual value is still in service, its residual value is depreciated over its re-estimated service life.

When property, plant and equipment are retired or disposed of, their costs and accumulated depreciation are removed from the accounts and any gain or loss is credited or charged to income.

Asset Impairment

The Company evaluates whether or not there are indications that assets (primarily property, plant and equipment, deferred charges and goodwill) may be impaired on the balance sheet date. If there are indications, the Company estimates the recoverable amount for the asset. If an asset’s recoverable amount is lower than its carrying amount, the carrying amount of the asset is reduced to its recoverable amount by recording a charge to the accumulated impairment account of the asset and such a reduction is recognized as impairment loss in current period income. When the recoverable amount subsequently increases, then the impairment loss previously recognized would be reversed and recorded as a gain. However, the carrying

F-13

amount of an asset (other than goodwill) after the reversal of impairment loss should not exceed the carrying amount of the asset that would have been determined net of depreciation as if no impairment loss had been recognized.

Deferred Charges

Deferred charges consist of certain intangibles and other assets, including tools, utility, telecommunications and computer network systems. The amounts are amortized over the following periods: tools, 2 years; utility, telecommunications and computer network systems, 2 - 5 years; and others, 2 - 5 years.

Goodwill

Goodwill represents the excess of the consideration paid for an acquisition over the fair value of identifiable net assets acquired. Prior to January 1, 2006, goodwill was amortized using the straight-line method over the estimated life of 10 years. Effective January 1, 2006, pursuant to the newly revised SFAS No. 25, “Business Combinations-Accounting Treatment under Purchase Method” (“ROC SFAS No. 25”), goodwill is no longer amortized and instead is tested for impairment annually.

Employee Stock Options

All stock-based compensation for awards granted or modified after January 1, 2004 is accounted for by an interpretation issued by the Accounting Research and Development Foundation （ “ARDF” ） of the ROC. The compensation cost is measured based on the intrinsic value method, for which the compensation cost for stock options is measured as the excess, if any, of the quoted market price of the Company’s stock at the date of the grant over the amount an employee must pay to acquire the stock. Total compensation cost is recognized over the requisite service or vesting period.

Pension Costs

For employees under defined benefit pension plans, pension costs are recorded based on actuarial calculations. Pension costs include service cost, interest, amortization of unrecognized net obligation and expected return on plan assets.

For employees under defined contribution pension plans, pension costs are recorded based on the actual contribution made to employees’ personal pension accounts.

Shipping and Handling Costs

Shipping and handling costs are recorded as selling expenses and the amounts in 2004, 2005 and 2006 were $1,705 thousand, $1,382 thousand and $1,498 thousand, respectively.

Research and Development Costs

Research and development costs are charged to expense as incurred.

Income Taxes

The Company uses an inter-period tax allocation method for income tax. Tax effects of deductible temporary differences, unused tax credits and operating loss carryforward are recognized as deferred income tax assets, while taxable temporary differences are recognized as deferred income tax liabilities. A valuation allowance is provided to the extent that it is more likely than not that deferred income tax assets will not be realized.

F-14

Tax credits of ASE Test, Inc. from investments in machinery and equipment, research and development and employees’ training costs are recognized in the year acquired and expensed. Capital allowances of ASE Test Malaysia from investment in industrial buildings, machinery and equipment are recognized in the year in which they are acquired.

Adjustments of prior years’ income taxes are added to or deducted from the current year’s tax provision.

Income taxes on undistributed earnings (10%) of ASE Test, Inc., the Company’s Taiwan based subsidiary, are recorded as an expense in the year of shareholders’ approval.

Foreign Currency Transactions and Translation of Foreign-currency Financial Statements

The functional and reporting currency of ASE Test is U.S. dollar, while the functional currencies of its major subsidiaries, ASE Test, Inc., ASE Test Malaysia and ISE Labs, Inc. are their local currencies, namely, New Taiwan dollar, Malaysia Ringgit and U.S. dollar, respectively. Foreign currency transactions, except for derivative transactions, are recorded in the local currencies at the rates of exchange in effect when the transactions occur. Gains or losses resulting from the application of different foreign exchange rates when foreign-currency assets and liabilities denominated in foreign-currencies are settled are credited or charged to income in the year of settlement. At the end of year, monetary assets and liabilities denominated in foreign-currencies are revalued at the prevailing exchange rates and the resulting gains or losses are recognized in current period income.

The financial statements of the Company’s subsidiaries are translated into U.S. dollars at the end of year using the following rates: Assets and liabilities, current rates at the balance sheet date; shareholders’ equity, historical rates; and income and expenses, average rates during the year. The net resulting translation adjustment is reported as a separate component of shareholders’ equity.

Recent Accounting Pronouncements

In July 2006, the ROC ARDF issued ROC SFAS No. 37, “Intangible Assets”, which is required to be applied by the Company on January 1, 2007. The standard p rovides guidance on initial recognition and measurement, amortization, presentation and disclosure of intangible assets . An intangible asset should be measured initially at cost. For an intangible asset of a finite useful life; the carrying amount shall be amortized over its useful life. On the other hand, for an intangible asset with an indefinite useful life, the carrying amount shall not be amortized. Intangible assets shall be evaluated for impairment at least annually as required by ROC SFAS No. 35, “ Accounting for Impairment of Assets ” (“ROC SFAS No. 35”). The Company does not expect the adoption of the standard on January 1, 2007 to have a significant impact on its results of operations and financial position.

In November 2006, the ROC ARDF issued ROC SFAS No. 38, “Non-current Assets Held for Sale and Discontinued Operations” (“ROC SFAS No. 38”), which is also required to be applied by the Company on January 1, 2007. Under ROC SFAS No. 38, assets classified as held-for-sale shall be measured at the lower of carrying amounts or fair values and ceased to be depreciated or amortized. Any impairment loss shall be recognized in current earnings. Assets classified as held-for-sale shall be presented separately on the balance sheet. ROC SFAS No. 38 also requires the Company to disclose information of discontinued operations separately on the statements of income and cash flows or in a footnote. The Company does not expect the adoption of the standard on January 1, 2007 to have a significant impact on its results of operations and financial position.

In March 2007, the ROC ARDF issued an interpretation which requires ROC companies to recognize compensation expenses for bonuses paid to employees, directors and supervisors beginning January 1, 2008. Such bonuses are currently recorded as appropriations of earnings under ROC GAAP. On March 30, 2007, the ROC Financial Supervisory Commission also issued an interpretation which requires that bonuses granted to employees, directors and supervisors in the form of shares be valued at fair market value for purposes of compensation expenses.

Reclassifications

Certain accounts in the consolidated financial statements as of December 31, 2005 and for the years ended December 31, 2004 and 2005 have been reclassified to conform to the consolidated financial statements as of and for the year ended December 31, 2006.

3. ACCOUNTING CHANGES

On January 1, 2006, the Company adopted the newly released ROC SFAS No. 34, “Financial Instruments: Recognition and Measurement” (“ROC SFAS No. 34”) and No. 36, “Financial Instruments: Disclosure and Presentation” (“ROC SFAS No. 36”) and other revisions of previously released SFASs.

a. Effect of adopting the newly released SFASs and other revisions of previously released SFASs

The Company had categorized its financial assets and liabilities upon initial adoption of the newly released SFASs. The adjustments made to the carrying amounts of the financial instruments categorized as financial assets or liabilities at fair value through profit or loss were included in the cumulative effect of changes in accounting principles; on the other hand, the adjustments made to the carrying amounts of those categorized as available-for-sale financial assets were recognized as adjustments to shareholders’ equity.

Upon adoption of ROC SFAS No. 34 and No. 36 in January, carrying amounts of the available-for-sale financial assets were adjusted to fair value, and the Company recognized $83,751 thousand of unrealized gains as a separate component of shareholders’ equity as at January 1, 2006. Besides, there was no effect on net income for the year ended December 31, 2006.

Effective January 1, 2006, the Company adopted the newly revised ROC SFAS No. 5 and No. 25, which prescribe that investment premiums, representing goodwill, be assessed for impairment at least on an annual basis instead of being amortized. Such a change in accounting principle resulted in an increase in net income of $4,966 thousand and basic earnings per share (after income tax) of $0.05 for the year ended December 31, 2006.

b. Reclassifications

Upon the adoption of ROC SFAS No. 34, certain accounts in the consolidated financial statements as of December 31, 2005 and for the years ended December 31, 2004 and 2005 were reclassified to conform to the consolidated financial statements as of and for the year ended December 31, 2006. The previously issued consolidated financial statements as of December 31, 2005 and for the years ended December 31, 2004 and 2005 were not required to be restated.

Certain accounting policies prior to the adoption of the newly released SFASs are summarized as follows:

Short-term investments

Short-term investments were recorded at historical cost and were carried at the lower of cost or market value as of the balance sheet date. An allowance or decline in value was provided and is charged to current income when the aggregate carrying amount of the investments exceeded the aggregate market value. A reversal of the allowance was recorded for a subsequent recovery in the aggregate market value.

Long-term Investments

Investments in companies wherein the Company did not exercise significant influence were carried at the lower of cost or market value. Allowances for decline in market value and unrealized loss on long-term investments in shares of stock (a deduction account in shareholders’ equity) were

F-16

made when the market value of an investment was lower than its carrying amount. If a decline in value of the stock investment was determined to be other than temporary, such decline in value was charged against current income.

Derivative financial instruments

(a)

Forward exchange contracts

Premiums or discounts on foreign currency forward exchange contracts which had been acquired to manage the risk associated with assets and liabilities denominated in foreign currencies arising from the difference between the forward rate and the spot rate at the date of each contract were deferred and amortized using the straight-line method over the contract periods. At year end, balances of the forward exchange receivables or payables were restated based on prevailing exchange rates and the resulting gain or loss was credited or charged to income. Any exchange gain or loss when the contract was settled was also credited or charged to income. In addition, the receivables and payables related to the forward contracts are netted with the resulting amount presented as either an other current asset or other current liability.

(b)

Option contracts

Written option contracts to purchase or sell foreign currencies entered into for hedging purposes are not recorded as assets or liabilities on the contract dates. Gains or losses upon settlement were credited or charged to income. Amounts received or paid were amortized over each contract period. At year end, the outstanding written option contracts were marked to market with charges to current income.

When the Company had a legally enforceable right to set off the recognized amount and intends either to settle on a net basis, or to realize the asset and the liability simultaneously, the difference between receivables and payables was accounted for as either a current asset or current liability; otherwise, the receivables and payables should be accounted for as an other current asset and other current liability, respectively.

In November 2005, ASE Test, Inc. and its parent company, ASE Inc., entered into a $100 million, three-year revolving accounts receivable securitization agreement with a bank and the credit line was increased to $200 million in June, 2006.

Under the agreement, ASE Test, Inc. and ASE Inc. transferred a pool of accounts receivable to the bank, who issued securities backed by these accounts receivable. Proceeds received from the bank were the net carrying value of the pool of accounts receivable, less a deferred purchase price receivable at 20% of accounts receivable sold, guarantee deposit, program fee and other related expenses. The Company lost control of these accounts receivable at the time of transfer to the bank, and therefore the transaction was accounted for as a sale of accounts receivable, for which the book value of the accounts receivable was derecognized and the difference between the book value and the proceeds received was recorded as a non-operating loss. The loss on sale of accounts receivable was $74 thousand and $1,028 thousand for the years ended December 31, 2005 and 2006, respectively.

After the transfer of the accounts receivable, the Company continues to service, administer, and collect these accounts receivable on behalf of the bank. The Company collects on the initial receivables and transfers certain new accounts receivable having similar value to replace the collected receivables. Collected receivables not yet replaced by new accounts receivable due to timing difference are recorded as other current liability on the balance sheet, which amounted to $4,397 thousand and $4,913 thousand as of December 31, 2005 and 2006, respectively. Total accounts receivable sold was $9,525 thousand and $12,463 thousand as of December 31, 2005 and 2006, respectively.

11. GOODWILL

The Company adopted ROC SFAS No. 35 on December 31, 2004, and recognized an impairment loss on goodwill of $26,500 thousand, which was determined based on the amount by which the carrying amount of the cash-generating unit exceeded its recoverable amount. The Company identified the goodwill related to the cash generating unit of ISE Labs. The recoverable amount was the “value-in-use” of ISE Labs, which was determined based on six-years of projected cash flows, discounted at a rate of 9.58%. The Company attributed the impairment of goodwill associated with the acquisition of ISE Labs primarily to a downward revision in the forecasted revenue of ISE Labs. The reduction in forecasted revenues was made in response to company estimates and industry trend data that suggested the outlook for semiconductor industry, and ISE Labs in particular, was less favorable than in prior years, including the year in which the Company acquired its interest in ISE Labs. The Company performed its annual goodwill impairment test on December 31, 2005 and 2006, and found no impairment. As described in Note 2, the goodwill was no longer amortized under ROC SFAS No. 25 after January 1, 2006. Amortization of the goodwill is reflected in general and administrative expenses in the consolidated statements of income and was $10,105 thousand and $4,966 thousand for each of the years ended December 31, 2004 and 2005.

Bank loans obtained by ASE Test Finance were restricted for the use in the redemption of ASE Test Finance’s and the Company’s loans. The Company and ASE Inc. provided guarantees for ASE Test Finance’s payment obligations under the $78,000 thousand loan. Under the guaranty, the Company is required to maintain certain financial ratios and the tangible net worth of the Company shall not be less than $450 million at any time.

Several loan agreements specify the following non-financial covenants:

Without the prior written consent from the majority of the banks, the Company should not:

Pledge its assets, assume liabilities or dispose of assets in excess of 20% of total assets, unless the transaction involves a transfer of assets between affiliates. Assets in exchange for other comparable or superior as to type are excluded from this covenant; or

Merge with any other entity or make investments in excess of $100 million or acquire material assets from another entity.

The abovementioned bank loan contracts have variable interest rates and are subject to adjustments by banks or changes in prime rate. In addition, several of the loan agreements have default provisions, whereby a default under one loan agreement may also trigger cross-defaults under other loan agreements.

As of December 31, 2005 and 2006, the Company was in compliance with its financial and non-financial covenants.

Long-term debt by currencies other than U.S. dollars as of December 31, 2005 and 2006 is as follows:

14. PENSION PLAN

The Labor Pension Act (the “Act”), which took effect in the ROC on July 1, 2005, provides for a pension mechanism that is deemed a defined contribution pension plan. The employees who were subject to the Labor Standards Law of the ROC before the enforcement of this Act may choose to be subject to the pension mechanism under this Act or may continue to be subject to the pension mechanism under the Labor Standards Law. For those employees who were subject to the Labor Standards Law before July 1, 2005, work for the same company after July 1, 2005 and choose to be subject to the pension mechanism under the Act, their service years as of July 1, 2005 will be retained. Under the Act, the rate of an employer’s monthly contribution to the employees’ personal pension accounts should not be less than 6% of each employee’s monthly salary or wage.

INCOME TAX

The ROC government enacted the Alternative Minimum Tax Act (the “AMT Act”), which became effective on January 1, 2006. The alternative minimum tax (“AMT”) imposed under the AMT Act is a supplemental tax levied at a rate of 10% which is payable if the income tax payable determined pursuant to the Income Tax Law is below the minimum amount prescribed under the AMT Act. The taxable income for calculating the AMT includes most of the income that is exempted from income tax under various laws and statutes. ASE Test, Inc., the Company’s Taiwan based subsidiary, has considered the impact of the AMT Act in the determination of its tax liabilities.

(Concluded)

In assessing the realization of deferred income tax assets, the Company considers its future taxable earnings and expected timing for the reversal of temporary differences. In addition, in the event future taxable earnings do not materialize, the Company will consider executing certain tax planning strategies available to realize the deferred income tax assets. The valuation allowance is provided to reduce the gross deferred income tax assets to an amount which the Company believes will more likely than not be realized. Deferred income tax assets and liabilities are classified in the consolidated balance sheets based on the classification of the related assets or liabilities or the expected timing of the reversal of temporary differences.

As of December 31, 2006, unused tax credits which can be utilized to offset future income tax, are set forth below:

SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES FOLLOWED BY THE COMPANY AND ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE UNITED STATES OF AMERICA

The Company’s consolidated financial statements have been prepared in accordance with ROC GAAP, which differ in the following respects from U.S. GAAP:

Pension benefits

ASE Test, Inc. adopted U.S. Statement of Financial Accounting Standards (“U.S. SFAS”) No. 87, “Employers’ Accounting for Pensions” (“U.S. SFAS No. 87”) on January 1, 1987, which requires the Company to determine the accumulated pension obligation and the pension expense on an actuarial basis.

U.S. SFAS No. 87 was amended by U.S. SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans” (“U.S. SFAS No. 158”) on September 29, 2006, which requires employers to recognize the overfunded or underfunded status of a defined benefit pension plan as an asset or liability in its statement of financial position and to recognize changes in that funded status in the year in which the changes occur through comprehensive income. U.S. SFAS No. 158 defines the funded status of a benefit plan as the difference between the fair value of the plan assets and the projected benefit obligation. Previously unrecognized items such as gains or losses, prior service credits and transition assets or liabilities will be recognized in accumulated other comprehensive income and will be subsequently recognized through net periodic benefit cost pursuant to the provisions of U.S. SFAS No. 87. The Company adopted U.S. SFAS No. 158 on December 31, 2006.

ROC SFAS No. 18, “Accounting for Pensions” (“ROC SFAS No. 18”) is similar in many respects to U.S. SFAS No. 87 and was adopted by ASE Test, Inc. in 1996. However, ROC SFAS No. 18 does not require a company to recognize the overfunded or underfunded status of a defined benefit pension plan as an asset or liability in the statement of financial position. The difference in the dates of adoption gives rise to a U.S. GAAP difference in the actuarial computation for transition obligation pension expense and the related amortization.

Marketable securities

Under ROC GAAP, prior to January 1, 2006, marketable securities were carried at the lower of aggregate cost or market, and securities without active market were carried at cost, with only unrealized losses or impairment loss recognized. Effective January 1, 2006, the Company adopted ROC SFAS No. 34 and No. 36. Financial instruments including debt securities and equity securities are recognized at fair value or including transaction costs and categorized as financial assets or liabilities at fair value through profit or loss (“FVTPL”), available-for-sale (“AFS”) or held-to-maturity (“HTM”) securities. FVTPL has two sub-categories, financial assets designated on initial recognition as one to be measured at fair value, and those that are classified as held for trading, which are also measured at fair value with fair value changes recognized in profit and loss. These classifications are similar to

F-38

those required by U.S. SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities” (“U.S. SFAS No. 115”).

Under U.S. SFAS No. 115, debt and equity securities that have readily determinable fair values are classified as either trading, available-for-sale or held-to-maturity securities. Debt securities that the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity securities and reported at amortized cost. Debt and equity securities that are bought and traded for short-term profit are classified as trading securities and reported at fair value, with unrealized gains and losses included in earnings. Debt and equity securities not classified as either held-to-maturity or trading are classified as available-for-sale securities and reported at fair value, with unrealized gains and losses excluded from earnings and reported as a separate component of shareholders’ equity.

ROC SFAS No. 34 and No. 36 require the Company to adjust the carry amount of trading and available-for-sale marketable securities from the lower of aggregate cost or market to fair value upon initial adoption. Since the Company did not hold any marketable securities at December 31, 2005, no adjustments were made as a result of the adoption of these new standards. No GAAP differences exist in the carrying amount and unrealized gains and losses for marketable securities acquired after January 1, 2006.

Bonuses to employees, directors and supervisors

According to ROC regulations and the Articles of Incorporation of ASE Inc. and ASE Test, Inc., a portion of the Company’s earnings is required to be set aside as bonuses to employees, directors and supervisors. Bonuses to directors and supervisors are always paid in cash. However, bonuses to employees may be granted in cash or stock or both. All of these appropriations, including stock bonuses which are valued at par value of NT$10, are charged against retained earnings under ROC GAAP after such appropriations are formally approved by the shareholders in the following year.

Under U.S. GAAP, such bonuses are charged against income in the year earned. Shares issued as part of these bonuses are recorded at fair market value. The total amount of the aforementioned bonuses to be paid in the following year is initially accrued based on management’s estimate pursuant to the Company‘s Articles of Incorporation. Any difference between the initially accrued amount and the fair market value of any shares issued as bonuses is recognized in the year of approval by shareholders, which normally occurs during the subsequent year.

ASE Inc. pays the bonuses on behalf of the Company and does not require reimbursement. For U.S. GAAP reporting purposes, bonus payments made by ASE Inc. directly to ASE Test, Inc.’s employees are recorded as compensation expense for the Company and credited to additional paid-in capital.

The impact of bonuses under U.S. GAAP to specific cost and expense categories is as follows:

	2004		2005			2006

Cost of revenues	$	2,591	$	(1,546	)	$	8,079
Selling, general and administrative expenses		1,080		(1,420	)		3,872
Research and development		418		(236	)		1,235

	$	4,089	$	(3,202	)	$	13,186

Depreciation of buildings

Under ROC GAAP, buildings may be depreciated over their estimated life or up to 40 years based on ROC practices and tax regulations. For U.S. GAAP purposes, buildings are depreciated over their estimated economic useful life of 25 years.

F-39

Depreciation on the excess of book value on transfer of buildings between related parties

ASE Test, Inc. purchased buildings and facilities from its affiliate, ASE Technology, in 1997. The purchase price was based on market value, which represented the portion of the purchase price in excess of the book value NT$17,667 thousand (US$642 thousand) was capitalized by ASE Test, Inc. as allowed under ROC GAAP. Under U.S. GAAP, transfers of assets between related parties are recorded at historical costs. Therefore, depreciation on the capitalized amount recorded under ROC GAAP is reversed under U.S. GAAP until the buildings and facilities are fully depreciated or disposed.

Impairment of long-lived assets

Under U.S. 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. Effective January 1, 2002, long-lived assets (excluding goodwill and other indefinite 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.

Under ROC GAAP, effective January 1, 2005, the Company is required to recognize an impairment loss when an indication is identified that the carrying amount of an asset or a group of assets is not recoverable from the expected future cash flows. However, if the recoverable amount increases in a future period, the amount previously recognized as impairment would be reversed and recognized as a gain. The adjusted amount may not exceed the carrying amount that would have been determined, net of depreciation, if no impairment loss had been recognized.

Prior to January 1, 2005, the Company followed U.S. GAAP in accounting for impairment of long-lived assets for ROC GAAP purposes.

As discussed in Note 21, the Company reversed $5,641 thousand of impairment loss recognized in 2005 under ROC GAAP after a careful analysis of the increase in the estimated service potential of the production line facilities by an external specialist. Such reversal is prohibited under U.S. GAAP. As such, differences in the cost basis of these damaged machinery and equipment and associated depreciation expense between ROC and U.S. GAAP are reflected in the reconciliation.

Derivative financial instruments

Under ROC GAAP, prior to January 1, 2006, there were no specific accounting standards which addressed measurement for derivative instruments, except for foreign currency forward contracts. Forward contracts were accounted for in a manner similar to that required under U.S. SFAS No. 52, “Foreign Currency Translation”. Effective January 1, 2006, the Company adopted ROC SFAS No. 34 which requires derivatives that do not qualify for hedge accounting be recorded as FVTPL as described in Note 2.

Under U.S. GAAP, accounting for derivative instruments is covered under U.S. SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” (“U.S. SFAS No. 133”), as amended by U.S. SFAS No. 138, “Accounting for Certain Derixxvative Instruments and Certain Hedging Activities”, which require that all companies recognize derivative instruments as assets and liabilities in the statements of financial position at fair value. If certain conditions are met, companies may elect to designate a derivative instrument as a hedge. For U.S. GAAP reporting purposes, the Company does not apply hedge accounting, and derivatives have historically been, and will continue to be, recorded on the consolidated balance sheets at fair value, with changes in fair value recorded through current period earnings.

F-40

Stock-based compensation

Under U.S. GAAP, stock-based compensation expense for the year ended December 31, 2006 includes compensation expense for all unvested stock-based compensation awards granted prior to January 1, 2006 that are expected to vest, based on the grant date fair value estimated in accordance with the transition method and the original provision of U.S. SFAS No. 123, “Accounting for Stock-Based Compensation” (“U.S. SFAS No. 123”). Upon an employee’s termination, unvested awards are forfeited, which affects the quantity of options to be included in the calculation of stock-based compensation expense. Forfeitures do not include vested options that expire unexercised. Stock-based compensation expense for all stock-based compensation awards granted after January 1, 2006 is based on the grant-date fair value estimate in accordance with the provisions of U.S. SFAS No. 123R, “Share-Based Payment” (“U.S. SFAS No. 123R”). The Company recognizes these compensation costs using the graded vesting method over the requisite service period of the award, which is generally the option vesting term of five years. Prior to the adoption of U.S. SFAS No. 123R, the Company recognized stock-based compensation expense in accordance with U.S. Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”). See Note 25e for a further discussion on stock-based compensation.

ASE Inc. pays certain employee compensation amounts, by means of stock options, on behalf of the Company and does not require reimbursement. For U.S. GAAP reporting purposes, such payments made by ASE Inc. directly to the employees of ASE Test and subsidiaries are recorded as compensation expense for the Company and credited to additional paid-in capital.

Certain characteristics of the stock options granted under the ASE 2002 Option Plan made the fair values of these options not reasonably estimable using appropriate valuation methodologies as prescribed under U.S. SFAS No. 123 and have been accounted for using the intrinsic value method. Upon the adoption of U.S. SFAS No. 123R, the Company continued to account for these stock options based on its intrinsic value, remeasured at each reporting date through the date of exercise or other settlement.

Under ROC GAAP, employee stock option plans that are amended or have options granted on or after January 1, 2004 must be accounted for by an interpretation issued by the ARDF in the ROC. The Company adopted the intrinsic value method and any compensation expense determined using this method is recognized over the vesting period. No stock-based compensation expense was recognized under ROC GAAP for the years ended December 31, 2004, 2005 and 2006.

Goodwill

Prior to January 1, 2006, under ROC GAAP, the Company amortized goodwill arising from acquisitions over 10 years. The Company adopted ROC SFAS No. 35 on December 31, 2004, and in accordance with this new standard, performed an impairment analysis and recorded an impairment charge of $26,500 thousand for the year ended December 31, 2004 based on a “recoverable amount” as determined by an estimate of discounted cash flows for the next six years. The Company found no impairment as of December 31, 2005 and 2006.

Effective January 1, 2006, the Company adopted ROC SFAS No. 25 which is similar to U.S. SFAS No. 142, “Goodwill and Other Intangible Assets’’ (“U.S. SFAS No. 142”). The Company ceased amortization and reviewed goodwill for impairment in accordance with the provisions of the standard and ROC SFAS No. 35. Total amortization expenses of goodwill under ROC GAAP were $10,105 thousand and $4,966 thousand in 2004 and 2005, respectively.

Under U.S. GAAP, the Company adopted the provisions of U.S. SFAS No. 142 on January 1, 2002. U.S. SFAS No. 142 requires the Company to review for possible impairment of goodwill existing at the date of adoption and perform subsequent impairment tests on at least an annual basis. In addition, existing goodwill and intangible assets must be reassessed and classified consistently in accordance with the criteria set forth in U.S. SFAS No. 141 “Business Combinations’’ and U.S. SFAS No. 142.

F-41

As a result, the Company ceased to amortize goodwill effective January 1, 2002. Definite lived intangible assets will continue to be amortized over their estimated useful lives.

The determination of whether or not the goodwill is impaired under U.S. SFAS No. 142 is made by first estimating the fair value of the reporting unit and comparing such fair value with its carrying amount, including goodwill. If the carrying amount exceeds the fair value, the Company calculates an implied fair value of the goodwill based on an allocation of the fair value of the reporting unit to its underlying assets and liabilities. If the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. For the year ended December 31, 2004, the Company recognized an impairment loss of $41,500 thousand for U.S. GAAP purposes.

Undistributed earnings tax

In the ROC, a 10% tax is imposed on unappropriated earnings (excluding earnings from foreign consolidated subsidiaries). For ROC GAAP purposes, the Company records the 10% tax on unappropriated earnings in the year of shareholders’ approval. Starting from 2002, the American Institute of Certified Public Accountants International Practices Task Force (the "Task Force") concluded that in accordance with Emerging Issues Task Force (EITF) 95-10, “Accounting for tax credits related to dividends in accordance with SFAS 109,” the 10% tax on unappropriated earnings should be accrued under U.S. GAAP during the period the earnings arise and adjusted to the extent that distributions are approved by the shareholders in the following year.

Investments in parent company accounted for as treasury stock

Under ROC GAAP, shareholdings in the parent company are recorded as an available-for-sale financial asset and changes in fair value from a subsequent remeasurement are reported as a separate component of shareholders’ equity. Under U.S. GAAP, according to ARB No. 51, “Consolidated Financial Statements”, there is a presumption that the parent company must approve the subsidiary's transactions. Accordingly, unless this presumption can be overcome, the investment in the parent company's stock should be presented within the equity section of a wholly owned subsidiary's separate financial statements and be accounted for in the same manner as treasury stock. Upon the company’s receipt of cash dividend distributed by the parent company, the cash dividend should be recorded as additional paid-in capital.

Earnings per share

Under both ROC GAAP and U.S. GAAP, basic earnings per share is calculated by dividing net income by the average number of shares outstanding in each period. Other shares issued from unappropriated earnings, such as stock bonuses to employees, are included in the calculation of weighted-average number of shares outstanding from the date of occurrence. For diluted earnings per share, unvested stock options are included in the calculation using the treasury stock method if the inclusion of such would be dilutive.

U.S. SFAS No. 128, “Earnings per Share” provides guidance on applying the treasury stock method for equity instruments granted in share-based payment transactions in determining diluted earnings per share, which states that the assumed proceeds shall be the sum of (a) the exercise price, (b) the amount of compensation cost attributed to future services and not yet recognized, and (c) the amount of excess tax benefits that would be credited to additional paid-in capital assuming exercise of the options. Prior to January 1, 2006, the Company used intrinsic value method to account for its stock-based compensation under both U.S. GAAP and ROC GAAP, resulting in no unrecognized compensation expense to be included in the assumed proceeds calculation. However, upon adoption of U.S. SFAS No. 123R, the Company now has unrecognized compensation costs, and therefore, the number of diluted shares included in the diluted earnings per share calculation under U.S. GAAP will be different from that under ROC GAAP.

(Concluded)

The Company applies ROC SFAS No. 17, “Statement of Cash Flows”. Its objectives and principles are similar to those set out in U.S. SFAS No. 95, “Statement of Cash Flows”. The principal differences between the two standards relate to classification. Cash flows from investing activities for changes in deferred charges, refundable deposits and other assets-miscellaneous, and cash flows from financing activities for changes in guarantee deposits, other liabilities and cash bonuses paid to employees, directors and supervisors are reclassified to operating activities under U.S. SFAS No. 95.

25. ADDITIONAL DISCLOSURES REQUIRED BY U.S. GAAP

Recently issued accounting standards

In February 2006, the FASB issued U.S. SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments - an amendment of FASB Statements No. 133 and 140” (“U.S. SFAS No. 155”). This Statement resolves issues addressed in Statement 133 Implementation Issue No. D1, “Application of Statement 133 to Beneficial Interests in Securitized Financial Assets.” U.S. SFAS No. 155 permits fair value remeasurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation, clarifies which interest-only strips and principal-only strips are not subject to the requirements of Statement 133, establishes a requirement to evaluate interests in securitized financial assets to identify interests that are freestanding derivatives or that are hybrid financial instruments that contain an embedded derivative requiring bifurcation, clarifies that concentrations of credit risk in the form of subordination are not embedded derivatives and amends Statement No. 140 to eliminate the prohibition on a qualifying special-purpose entity from holding a derivative financial instrument that pertains to a beneficial interest other than another derivative financial instrument. U.S. SFAS No. 155 is effective for all financial instruments acquired or issued after the beginning of an entity’s first fiscal year that begins after September 15, 2006. The fair value election provided for in this U.S. SFAS No. 155 may also be applied upon adoption of U.S. SFAS No. 155 for hybrid financial instruments that had been bifurcated under paragraph 12 of Statement 133 prior to the adoption of U.S. SFAS No. 155. Earlier adoption is permitted as of the beginning of an entity’s fiscal year, providing the entity has not yet issued financial statements for any interim period for that fiscal year. The Company does not expect the adoption of U.S. SFAS No. 155 to impact the Company’s consolidated financial position or results of operations.

F-46

In Marc h 2006, the FASB issued U.S. SFAS No. 156, “Accounting for Servicing of Financial Assets” (“U.S. SFAS No. 156”), which (i) provides revised guidance on when a servicing asset and servicing liability should be recognized, (ii) requires all separately recognized servicing assets and liabilities to be initially measured at fair value, if practicable, and (iii) permits an entity to elect to measure servicing assets and liabilities at fair value each reporting date and report changes in fair value in earnings in the period in which the changes occur. The Company believes that there is no impact on the results of operations and financial position of the Company upon adopting U.S. SFAS No. 156.

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

In September 2006, the FASB issued U.S. SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans—An Amendment of FASB Statements No. 87, 88, 106, and 132R” (“U.S. SFAS No. 158”). Provisions with respect to the recognition of an asset and liability related to the funded status and the changes in the funded status be reflected in comprehensive income are effective for fiscal years ending after December 15, 2006 and the change in measurement date provisions is effective for fiscal years ending after December 15, 2008. U.S. SFAS No. 158 also requires the measurement date of the plan’s funded status be the same as the Company’s fiscal year-end. The Company adopts all requirements of U.S. SFAS No. 158 in its fiscal year ended December 31, 2006. Upon the adoption of U.S. SFAS No. 158, the Company recognized a decrease to accumulated other comprehensive income of $1,712 thousand as of December 31, 2006.

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

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

Earnings (loss) per share

U.S. SFAS No. 128 requires the presentation of basic and diluted earnings per share. Basic earnings per share is computed based on the weighted average number of common shares outstanding during the year. Diluted earnings per share includes the effect of dilutive equivalent common shares (stock options issued during the year using the treasury stock method).

F-49

Following is a reconciliation of amounts used in the computation of basic and diluted earnings per share:

	2004		2005			2006

Net income (loss) under U.S. GAAP
Income (loss) from continuing operations	$	922	$	(46,285	)	$	116,937

	$	0.18	$	(0.35	)	$	1.17

The computation of diluted earnings per share exclude 10,803,859, 10,491,064 and 10,172,054 anti-dilutive options for the years ended December 31, 2004, 2005 and 2006, respectively. While these options were anti-dilutive for the respective periods, they could be dilutive in the future. No stock options were considered dilutive for the year ended December 31, 2005 as a result of net loss.

Stock option plans

Effective January 1, 2006, the Company adopted the fair value recognition provisions of U.S. SFAS No. 123R, using the modified prospective transition method and therefore has not restated the results of operations for prior years. Under this transition method, stock-based compensation expense for the year ended December 31, 2006 included stock-based compensation expense for all share-based payment awards granted prior to, but not yet vested as of January 1, 2006, based on the grant-date fair value estimated in accordance with the original provision of U.S. SFAS No. 123. In addition, the stock-based compensation expense also includes intrinsic value of certain outstanding share-based awards for which it was not possible to reasonable estimate their grant-date fair value under the requirement of U.S. SFAS No. 123. Stock-based compensation expense for all share-based payment awards granted after January 1, 2006 is based on the grant-date fair value estimated in accordance with the provision of U.S. SFAS No. 123R. The Company recognizes these compensation costs using the graded vesting method over the requisite service period of the award, which is generally a five-year vesting period. The adoption of U.S. SFAS No. 123R resulted in a cumulative gain from changes in accounting principle of $381 thousand, which reflects the net cumulative impact of estimating future forfeitures in the determination of period expense, rather than recording forfeitures when they occur as previously permitted. Prior to the adoption of U.S. SFAS No. 123R, the Company accounted for awards granted from ASE Inc. under the intrinsic value method prescribed by APB 25, and related

F-50

interpretations, and provided the required pro forma disclosures prescribed by U.S. SFAS No. 123. In March 2005, the SEC issued Staff Accounting Bulletin No. 107 (“SAB 107”) regarding SEC’s interpretation of U.S. SFAS No. 123R and the value of share-based payments for public companies. The Company has applied the provisions of SAB 107 in its adoption of U.S. SFAS No. 123R.

As a result of adopting U.S. SFAS No. 123R, income before income taxes and net income for the year ended December 31, 2006 were lower by $5,178 thousand and $3,884 thousand, respectively, than if the Company had continued to account for stock-based compensation under APB 25. The impact on both basic and diluted earnings per share for the year ended December 31, 2006 was a decrease of $0.04. In addition, prior to the adoption of U.S. SFAS No. 123R, the Company presented the tax benefit of stock options exercised as an operating cash flow.

Information regarding ASE Test’s and ASE Inc’s stock option plans is as follows.

ASE Test

ASE Test has three stock option plans, the 1999 Option Plan, 2000 Option Plan and 2004 Option Plan. Up to 2,000,000, 12,000,000, and 2,500,000 shares have been reserved for issuance under the 1999, 2000 and 2004 Option Plans, respectively.

The 1999, 2000 and 2004 Option Plans granted the following stock options to purchase ASE Test’s shares which vest ratably over a period of three or five years from the date of grant until the expiration of options, to directors, officers and key employees. If any granted shares are forfeited, the shares may be granted again, to the extent of any such forfeiture.

The exercise price under each of the aforementioned stock option plans was equal to the stock’s market price on the date of grant. Options granted under the 1999, 2000 and 2004 Option Plans expire 5 or 10 years after grant.

ASE Inc.

ASE Inc., the parent company, has two option plans, the 2002 Option Plan and 2004 Option Plan. The maximum number of units authorized to be granted under the 2002 and 2004 Option Plan is 160 million and 140 million, respectively, with each unit representing one share of ASE Inc. Under the terms of the plans, stock option rights are granted to employees, including those of the Company, which have an exercise price equal to the closing price of the ASE Inc. common stock as per the Taiwan Stock Exchange on the date of grant, and such exercise price is subject to retroactive adjustment in the event of certain capital transactions in subsequent periods. The option rights expire ten years from the date of grant. On the second anniversary of the grant date, 40% of the options become vested and the remaining options vest ratably over a period of three years thereafter. Under the 2002 and 2004 Option Plans, 41,603,100 and 28,499,550 units were granted, respectively, by ASE Inc. to employees of the Company.

As of December 31, 2006, the number of options that are expected to vest was 19,168,273.

Total intrinsic value of options exercised in the years ended December 31, 2004, 2005 and 2006 was $62 thousand, $ 1,331 thousand and $4,001 thousand, respectively.

The weighted average exercise price and remaining contractual life of the options outstanding as of December 31, 2006 are as follows:

The 2002 Option Plan is accounted for as a variable plan, as a result of a provision in the plan which would require an adjustment of the exercise price in accordance with a prescribed formula based on occurrence of certain future events. Accordingly, no adjustment is required for purposes of the pro forma compensation expense calculated in accordance with U.S. SFAS No. 123 before January 1, 2006 for these options. Upon the adoption of U.S. SFAS No. 123R, the Company continued to account for these stock options based on its intrinsic value, and remeasured at each reporting date through the date of exercise or other settlement.

F-53

The fair value of the option plan issued was determined using a Black-Scholes option pricing model with the following assumptions:

	2004		2005

Risk-free interest rate		2.50%		1.80%
Expected life		5 years		5 years
Expected dividend		3.00%		3.00%
Expected volatility		59%		47%

Prior to January 1, 2006, no compensation cost was recognized except 2002 Option Plan of ASE Inc. Therefore, for purposes of pro forma disclosure, the estimated fair values of the options are amortized to expense ratably over the option vesting periods. Had the Company recorded compensation costs based on the estimated grant date fair value for 2004 and 2005, as defined by U.S. SFAS No. 123, the Company’s net income (loss) would have been reduced to the pro forma amounts below (earnings (loss) per share in U.S. dollars).

	2004			2005

Net income (loss) based on U.S. GAAP	$	17,890		$	(35,446	)
Stock-based compensation expense (net of related tax effect)
From the Company		(13,998	)		(10,525	)

ASE Test Limited

We have reviewed the accompanying consolidated balance sheets of ASE Test Limited and its subsidiaries (collectively, the “Company”) as of September 30, 2006 and 2007, and the related consolidated statements of income for the three-month and nine-month period ended September 30, 2006 and 2007 and cash flows for the nine-month period ended September 30, 2006 and 2007, expressed in U.S. dollars. These interim consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to issue a report on these consolidated financial statements based on our reviews.

We conducted our reviews in accordance with Statements of Auditing Standard No. 36, “Review of Financial Statements” issued by the Auditing Committee of the Accounting Research and Development Foundation of the Republic of China and the standards of the Public Company Accounting Oversight Board (United States). A review of interim consolidated financial statements consists principally of applying analytical procedures to financial data and making inquiries of officers responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with auditing standards generally accepted in Republic of China and the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the interim consolidated financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should be made to such interim consolidated financial statements referred to above for them to be in conformity with the requirements of the Business Accounting Law and Guidelines Governing Business Accounting relevant to financial accounting standards, and accounting principles generally accepted in the Republic of China.

We have previously audited, in accordance with the Rules Governing the Audit of Financial Statements by Certified Public Accountants, auditing standards generally accepted in the Republic of China and the Standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of the Company as of December 31, 2006 and in our report dated April 30, 2007, we expressed an unqualified opinion on those consolidated balance sheet. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2006 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

As discussed in Note 20 to the interim consolidated financial statements, the Company incurred fire damage to its production line in Chung Li, Taiwan on May 1, 2005. The Company recognized an estimated loss of $52,014 thousand for the damage to its machinery and equipment, less $790 thousand of insurance receivable in 2005. The Company reached final settlement with the

insurers in June 2006 with regards to the fire damage referred to above. The final settlement amount of $27,289 thousand, less the $790 thousand recorded in 2005, was recorded as a gain for the nine months ended September 30, 2006. The Company also reversed $5,641 thousand of previously recorded impairment charges on these fire-damaged machinery and equipment due to an increase in the estimated service potential of the assets.

As discussed in Note 3 to the interim consolidated financial statements, the Company adopted Republic of China Statement of Financial Accounting Standards No. 34 “Financial Instruments: Recognition and Measurement”, No. 36 “Financial Instruments ： Disclosure and Presentation” and other revised Statements on January 1, 2006.

1.	ORGANIZATION AND OPERATION

Overview

ASE Test Limited (“ASE Test” or the “Company”) is a Singapore holding company which, through an exchange of its shares with its parent company, Advanced Semiconductor Engineering, Inc. (“ASE Inc.”), and other individuals, acquired substantially all of the shares of ASE Test, Inc. in May 1996. The exchange was accounted for as a reorganization of companies under common control. Since June 1996, the Company’s shares have been traded on the NASDAQ National Market （ “NASDAQ” ） in the United States under the symbol “ASTSF”.

J & R Holding Limited, a shareholder of the Company, offered 6,000,000 and 5,000,000 shares of the Company ’ s common stock in December 1997 and February 1999, respectively, in the form of Taiwan Depositary Receipts ( “ TDR s ” ). The TDRs are traded on the Taiwan Stock Exchange under the s ymbol “ 9101” and each TDR represents 0.0125 share of the Company ’ s stock.

Set forth is a brief overview of the Company ’ s organization s tructure.

The Company has four direct subsidiaries:

ASE Test, Inc. (incorporated in the Republic of China (“ROC”) in December 1987), which is engaged in the testing of semiconductors;

ASE Holdings (Singapore) Pte Ltd. (incorporated in Singapore in December 1994), which holds shares in ASE Test group companies;

ASE Test Holdings, Limited (“ASE Test Holdings”) (incorporated in Cayman Islands in April 1999), which holds shares in ASE Test group companies; and

ASE Test Finance Limited (“ASE Test Finance”) (incorporated in Mauritius in June 1999), which is engaged in financing activities.

ASE Holdings (Singapore) Pte Ltd . has a wholly-owned subsidiary, ASE Electronics (M) Sdn. Bhd. (“ ASE Test Malaysi a” ) (incorporated in Malaysia in February 1991), which is engaged in the packaging and testing of semiconductors .

ASE Test Holdings has a wholly-owned subsidiary, ISE Labs, Inc. (“ ISE Labs” ) (incorporated in California , U.S.A. in November 1983) . ISE Lab s and its wholly-owned subsidiaries, ASE Singapore Pte Ltd . , ISE Technology, Inc. and Digital Testing Services Inc., are engaged in the front-end engineering testing and final testing of semiconductors.

As of September 30, 2006, December 31, 2006 and September 30, 2007, the Company and its subsidiaries had approximately 5,400, 5,300 and 5,300 employees, respectively.

2.	SIGNIFICANT ACCOUNTING POLICIES

The accompanying interim consolidated financial statements have been prepared in conformity with Business Accounting Law, Guidelines Governing Business Accounting, and accounting principles generally accepted in the Republic of China (“ROC GAAP”). Under these law, guidelines and principles, the Company should reasonably estimate the amounts of allowances for doubtful accounts, allowance for sales discounts, inventory valuations, depreciation of property, plant, and equipment, loss on impairment of assets, pension expenses, gain (loss) on valuation of financial instrument and allowance of deferred income tax assets. Actual results may differ from these estimates. Significant accounting policies are summarized as follows:

Basis of Presentation

The Company prepares its interim consolidated financial statements using the aforementioned law, guidelines and principles with a reconciliation to accounting principles generally accepted in the United States of America (“U.S. GAAP”) (see Note 22) to be consistent with the basis of presentation of the interim consolidated financial statements of ASE Inc. The accompanying consolidated balance sheets are presented as of September 30, 2006, December 31, 2006 and September 30, 2007 and the accompanying consolidated statements of income and cash flows are presented for the three months and nine months ended September 30, 2006 and 2007.

The interim financial data is unaudited. However, in the opinion of management, the unaudited interim data includes all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of the results of the interim periods. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for a full year or any period.

Basis of Consolidation

The interim consolidated financial statements include the accounts of the Company and all of the aforementioned subsidiaries.

All significant intercompany accounts and transactions have been eliminated.

Current and Noncurrent Assets and Liabilities

Current assets include cash, financial assets held primarily for trading purposes and assets expected to be converted to cash, sold or consumed within one year from the balance sheet date. Current liabilities are obligations incurred for trading purposes and obligations expected to be settled within one year from the balance sheet date. Assets and liabilities that are not classified as current are noncurrent assets and liabilities, respectively.

Financial Assets and Liabilities at Fair Value through Profit or Loss

Financial instruments classified as financial assets or financial liabilities at fair value through profit or loss consist of financial assets or financial liabilities held for trading. These financial instruments are initially recognized at fair value, with associated transaction costs expensed as incurred. The financial instruments are subsequently remeasured at fair value, and changes in fair value are recognized in current income (loss). A regular way purchase or sale of financial assets is recognized and derecognized using settlement date accounting.

Derivatives which are not qualified for hedge accounting are recorded as financial assets or liabilities at fair value through profit or loss. Fair value of derivatives with no active market fair value is estimated using valuation techniques.

Available-for-Sale Financial Assets

Available-for-sale financial assets are initially recognized at fair value plus transaction costs that are directly attributable to the acquisition. At each balance sheet date subsequent to initial recognition, available-for-sale financial assets are remeasured at fair value. Changes in fair value of financial assets are reported in a separate component of shareholders’ equity. The corresponding accumulated gains or losses are recognized in earnings when the financial asset is derecognized from the balance sheet. A regular way purchase or sale of financial assets is accounted for using settlement date accounting.

Cash dividends are recognized on the ex-dividend date, except for dividends distributed from the pre-acquisition profit which are treated as a reduction of investment cost. Stock dividends are not recognized as investment income but are recorded as an increase in the number of shares. The total number of shares subsequent to the increase is used for recalculation of cost per share.

Fair value for beneficiary certificates of open-ended mutual funds and publicly traded stocks are determined using the net asset value and closing-price at the balance sheet date , respectively.

If certain objective evidence indicates that such available-for-sale financial asset is impaired, a loss should be recognized currently. If, in a subsequent period, the amount of the impairment loss decreases, for equity securities, the previously recognized impairment loss is reversed to the extent of the decrease and recorded as an adjustment to shareholders’ equity.

Revenue Recognition, Accounts Receivable and Allowance for Doubtful Accounts

Revenues from semiconductor packaging services are recognized upon shipment. Revenues from semiconductor testing services are recognized upon completion of the services or shipment. The Company does not take ownership of: (i) bare semiconductor wafers received from customers that the Company packages into finished semiconductors, and (ii) packaged semiconductors received from customers that the Company tests as to whether they meet certain performance specifications. The title and risk of loss remain with the customer for those bare semiconductors and/or packaged semiconductors. Accordingly, costs of customer-supplied semiconductors materials are not included in the accompanying interim consolidated financial statements. Other criteria the Company uses to determine when to recognize revenue are: (i) existence of persuasive evidence of an arrangement, (ii) the selling price is fixed or determinable and (iii) collectibility is reasonably assured.

Allowance for doubtful accounts is provided based on an evaluation of the collectibility of receivables. The Company determines the amount of allowance for doubtful receivables by examining the aging analysis of the outstanding accounts receivable and current trends in the credit quality of its customers. An appropriate sales allowance, based on historical experience, is recognized in the same period the sale is recognized.

Accounts Receivable Securitization

Accounts receivable securitization is the transfer of a designated pool of accounts receivable to a bank, which in turn issues beneficial securities or asset-backed securities based on the accounts receivable. Under ROC Statement of Financial Accounting Standards (ROC SFAS) No. 33 “ Accounting for Transfers of Financial Assets and Extinguishments of Liabilities” , such transfer of financial assets in which the transferor surrenders control over those assets is accounted for as a sale to the extent that consideration other than beneficial interests in the transferred assets is received in exchange. The difference between the book value of accounts receivable and total proceeds received is recorded as a gain or loss on disposal of financial assets.

Inventories

Equity Method Investments

Investments in companies of which the Company owns at least 20% of the outstanding voting shares or where the Company exercises significant influence over the investee company’s operating and financial policy decisions are accounted for using the equity method. Prior to January 1, 2006, the difference, if any, between the cost of investment and the Company’s proportionate equity in the fair value of the net assets of the investees at the time of investments or at the time the equity method of accounting is first applied to a particular investment, is amortized on the straight-line method over 10 years. Effective January 1, 2006, pursuant to the revised ROC SFAS No. 5, “Long-term Investments under Equity Method” ( ROC SFAS No. 5), the cost of an investment shall be analyzed and the difference between the cost of investment and the fair value of identifiable net assets acquired, representing goodwill, shall not be amortized and instead shall be tested for impairment annually. The accounting treatment for the investment premiums acquired before January 1, 2006 is the same as that for goodwill which is no longer being amortized. When an indication of impairment is identified, the carrying amount of the investment is reduced, with the related impairment loss recognized in earnings.

Financial Assets Carried at Cost

Property, Plant and Equipment

Property, plant and equipment, except for machinery and equipment under operating lease, are stated at cost less accumulated depreciation and accumulated impairment. Machinery and equipment held under capital leases are recorded as an asset and an obligation at an amount equal to the lower of: (i) the present value at the beginning of the lease term of the minimum lease payments during the lease term (including the payment called for under any bargain purchase option); or (ii) fair value of the leased machinery and equipment at the inception of the lease. Machinery in transit, construction in progress and prepayments under construction are stated at cost. These include the cost of machinery, construction, down payments and other direct costs plus interest charges attributable to the borrowings used to finance the acquisitions of these assets. Major overhauls and improvements are capitalized, while maintenance and repairs are expensed as incurred.

Depreciation is computed using the straight-line method over estimated service lives, which range as follows: buildings and improvements, 3 to 40 years; machinery and equipment, 2 to 6 years; furniture and fixtures, 1 to 8 years and leased assets, 1 to 7 years. Leasehold improvements and improvements on building and business flats are amortized on a straight-line basis over the shorter of the useful life of the improvements or the lease term of the building. In the event that an asset depreciated to its residual value is still in service, its residual value is depreciated over its re-estimated service life.

When plant and equipment are retired or disposed of, their costs and accumulated depreciation are removed from the accounts and any gain or loss is credited or charged to income.

Asset I mpairment

The Company evaluates whether or not there are indications that assets (primarily property, plant and equipment, deferred charge and goodwill) may be impaired on the balance sheet date. If there are indications, the Company should estimate the recoverable amount for the asset. If an asset’s recoverable amount is lower than its carrying amount, the carrying amount of the asset should be reduced to its recoverable amount by recording a charge to the accumulated impairment account of the asset and such reduction should be recognized as impairment loss in current period income. When the recoverable amount subsequently increases, then the impairment loss previously recognized would be reversed and recorded as a gain. However, the carrying amount of an asset (other than goodwill) after the reversal of impairment loss should not exceed the carrying amount of the asset that would have been determined net of depreciation as if no impairment loss had been recognized.

Deferred Charges

Deferred charges consist of certain intangibles and other assets, including tools, utility, telecommunications and computer network systems. The amounts are amortized as follows: tools, 2 years; utility, telecommunications and computer network systems, 2 - 5 years; and others, 2 - 5 years.

Goodwill

Goodwill represents the excess of the consideration paid for an acquisition over the fair value of identifiable net assets acquired. Prior to January 1, 2006, goodwill was amortized using the straight-line method over the estimated life of 10 years. Effective January 1, 2006, pursuant to the newly revised ROC SFAS No. 25, “Business Combinations - Accounting Treatment under Purchase Method” (ROC SFAS No. 25), goodwill is no longer amortized and instead is tested for impairment annually.

Employee Stock Options

All stock-based compensation for awards granted or modified after January 1, 2004 is accounted for by the related Interpretations of Accounting Research and Development Foundation (“ARDF”) in ROC. The compensation cost is measured based on the intrinsic value method, for which the compensation cost for stock options is measured as the excess, if any, of the quoted market price of the Company’s stock at the date of the grant over the amount an employee must pay to acquire the stock. Total compensation cost is recognized as expense over the requisite service or vesting period.

Pension Cost

For employees under defined benefit pension plan, pension costs are recorded based on actuarial calculations. Pension costs include service costs, interest, amortization of unrecognized net obligation and expected return on pension assets.

For employees under defined contribution pension plan, pension costs are recorded based on the actual contribution made to employee’s personal pension accounts.

Research and Development Costs

Research and development costs are charged to expense as incurred.

Income Taxes

The Company uses an inter-period tax allocation method for income tax. T ax effects of deductible temporary differences, unused tax credits and opera ting loss carryforward are recognized as deferred income tax assets, while taxable temporary differences are recognized as deferred income tax liabilities . A v aluation allowance is provided to the extent that it is more likely than not that deferred incom e tax assets will not be realized .

Adjustments of prior years’ income taxes are added to or deducted from the current year’s tax provision.

Income taxes on undistributed earnings (10%) of ASE Test, Inc., the Company’s Taiwan based subsidiary, are recorded as an expense in the year of shareholders’ approval.

Foreign Currency Transactions and Translation of Foreign-currency Financial Statements

The functional and reporting currency of ASE Test is U.S. dollar, while the functional currencies of its major subsidiaries, ASE Test, Inc., ASE Test Malaysia and ISE Labs, Inc. are their local currencies, namely, New Taiwan dollar, Malaysia Ringgit and U.S. dollar, respectively. Foreign currency transactions, except for derivative transactions, are recorded in the local currencies at the rates of exchange in effect when the transactions occur. Gains or losses resulting from the application of different foreign exchange rates when foreign-currency assets and liabilities denominated in foreign-currencies are settled are credited or charged to income in the period of settlement. At the balance sheet date, monetary assets and liabilities denominated in foreign-currencies are revalued at the prevailing exchange rates and the resulting gains or losses are recognized in current period income.

The financial statements of the Company’s subsidiaries are translated into U.S. dollars at the end of period using the following rates: Assets and liabilities, current rate at the balance sheet date; shareholders’ equity, historical rates; dividend, current rate at the dividend declaration date; and income and expenses, average rate during the period. The net resulting translation adjustment is reported as a separate component of shareholders’ equity.

Hedging Derivative Financial Instruments

Derivatives that qualify as effective hedging instruments are measured at fair value, with subsequent changes in fair value recognized either in profit or loss, or in shareholders’ equity, depending on the nature of the hedging relationship.

Hedge Accounting

Hedge accounting recognizes the offsetting effects on profit or loss of changes in the fair values of the hedging instrument and the hedged item as follows:

Fair value hedge

The gain or loss from remeasuring the hedging instrument at fair value and the gain or loss on the hedged item attributable to the hedged risk are recognized in profit or loss.

Cash flow hedge

The portion of the gain or loss on the hedging instrument that is determined to be an effective hedge is recognized in shareholders’ equity. The amount recognized in shareholders’ equity is recognized in profit or loss in the same period or periods during which the hedged forecast transaction or an asset or liability arising from the hedged forecast transaction affects profit or loss. However, if all or a portion of a loss recognized in shareholders’ equity is not expected to be recovered in the future, the amount that is not expected to be recovered is reclassified into profit or loss.

3.	EFFECTS OF CHANGES IN ACCOUNTING PRINCIPLES

Adoption of New and Revised Standards

On January 1, 2007, the Company adopted the newly released ROC SFAS No. 37, “Intangible Assets” and ROC SFAS No. 38 “Non-current Assets Held for Sale and Discontinued Operations”. The Company believes that there is no impact on the results of operations and financial position of the Company after adopting ROC SFAS No. 37 and ROC SFAS No. 38.

On January 1, 2006, the Company adopted the newly released ROC SFAS No. 34, “Financial Instruments: Recognition and Measurement” (ROC SFAS No. 34) and No. 36, “Financial Instruments: Disclosure and Presentation” (ROC SFAS No. 36) and other revisions of previously released SFASs.

Upon adoption of ROC SFAS No. 34 and No. 36 in January, 2006, carrying amounts of the available-for-sale financial assets were adjusted to fair value, and the Company recognized $83,751 thousand of unrealized gain as a separate component of shareholders’ equity as at January 1, 2006. Besides, there was no effect on net income for the nine months ended September 30, 2006.

Effective January 1, 2006, the Company adopted the newly revised ROC SFAS No. 5 and No. 25, which prescribe that investment premiums, representing goodwill, be assessed for impairment at least on an annual basis instead of being amortized. Such a change in accounting principle resulted in an increase in net income of $3,725 thousand and basic earnings per share (after income tax) of $0.04 for the nine months ended September 30, 2006.

Recent Accounting Pronouncements

In March 2007, ARDF issued an interpretation that requires ROC companies to recognize compensation expenses for bonuses paid to employees, directors and supervisors beginning January 1, 2008. Such bonuses are currently recorded as appropriation of earnings under ROC GAAP.

The ARDF also issued ROC SFAS No. 39, “Share-based Payment” (ROC SFAS No. 39) in August 2007, which requires companies to record share-based payment transactions in the financial statements at fair value. ROC SFAS No. 39 should be applied to financial statements for the fiscal year beginning on or after January 1, 2008.

Under the agreement, ASE Test, Inc. and ASE Inc. transferred a pool of accounts receivable to the bank, who issued securities backed by these accounts receivable. Proceeds received from the bank were the net carrying value of the pool of accounts receivable, less a deferred purchase price receivable at 20% of accounts receivable sold, guarantee deposit, program fee and other related expenses. The Company lost control of these accounts receivable at the time of transfer to the bank, and therefore the transaction was accounted for as a sale of accounts receivable, for which the book value of the accounts receivable was derecognized and difference between the book value and the proceeds received was recorded as non-operating loss. Loss on sale of accounts receivable were $749 thousand and $336 thousand for the nine months ended September 30, 2006 and 2007, respectively.

After the transfer of the accounts receivable, the Company continues to service, administer, and collect these accounts receivable on behalf of the bank. The Company collects on the initial receivables and transfers certain new accounts receivable having similar value to replace the collected receivables. Collected receivables not yet replaced by new accounts receivable due to timing difference are recorded as other current liability on the balance sheet, which amounted to $4,657 thousand, 4,913 thousand and $1,367 thousand as of September 30, 2006, December 31, 2006 and September 30, 2007.

SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES FOLLOWED BY THE COMPANY AND ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE UNITED STATES OF AMERICA

The Company’s interim consolidated financial statements have been prepared in accordance with ROC GAAP, which differ in the following respects from U.S. GAAP:

Pension benefits

ASE Test, Inc. adopted U.S. Statement of Financial Accounting Standards (U.S. SFAS) No. 87, “Employers’ Accounting for Pensions” (U.S. SFAS No.87) on January 1, 1987, which requires the Company to determine the accumulated pension obligation and the pension expense on an actuarial basis.

U.S. SFAS No. 87 was amended by U.S. SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans” (U.S. SFAS No.158) on September 29, 2006, which requires employers to recognize the overfunded or underfunded status of a defined benefit pension plan as an asset or liability in its statement of financial position and to recognize changes in that funded status in the period in which the changes occur through comprehensive income. U.S. SFAS No. 158 defines the funded status of a benefit plan as the difference between the fair value of the plan assets and the projected benefit obligation. Previously unrecognized items such as gains or losses, prior service credits and transition assets or liabilities will be recognized in accumulated other comprehensive income and will be subsequently recognized through net periodic benefit cost pursuant to the provisions of U.S. SFAS No. 87. The Company adopted U.S. SFAS No.158 on December 31, 2006.

ROC SFAS No. 18 “Accounting for Pensions” is similar in many respects to U.S. SFAS No. 87 and was adopted by ASE Test, Inc. in 1996. However, ROC SFAS No. 18 does not require a company to recognize the overfunded or underfunded status of a defined benefit pension plan as an asset or liability in the statement of financial position. The difference in the dates of adoption gives rise to a U.S. GAAP difference in the actuarial computation for transition obligation pension expense and the related amortization.

Bonuses to employees, directors and supervisors

According to ROC regulations and the Articles of Incorporation of ASE Inc. and ASE Test, Inc. a portion of the Company’s earnings is required to be set aside as bonuses to employees, directors and supervisors. Bonuses to directors and supervisors are always paid in cash. However, bonuses to employees may be granted in cash or stock or both. All of these appropriations, including stock bonuses which are valued at par value of NT$10, are charged against retained earnings under ROC GAAP after such appropriations are formally approved by the shareholders in the following year.

Under U.S. GAAP, such bonuses are charged against income in the accounting period earned. Shares issued as part of these bonuses are recorded at fair market value. The total amount of the aforementioned bonuses to be paid in the following year is initially accrued based on management’s estimate pursuant to the Company‘s Articles of Incorporation in the period in which shareholders’ approval is obtained, which normally occurs during the subsequent year. Any difference between the initially accrued amount and the fair market value of any shares issued as bonuses is recognized in the year of approval by shareholders.

The impact of bonuses under U.S. GAAP to specific cost and expense categories is as follows:

Depreciation of buildings

Depreciation on the excess of book value on transfer of buildings between related parties

ASE Test, Inc. purchased buildings and facilities from its affiliate, ASE Technology, in 1997. The purchase price was based on market value, which represented the portion of the purchase price in excess of book value NT$17,667 thousand (US$642 thousand) was capitalized by ASE Test, Inc. as allowed under ROC GAAP. Under U.S. GAAP, transfers of assets between related parties are recorded at historical costs. Therefore, depreciation on the capitalized amount recorded under ROC GAAP is reversed under U.S. GAAP until the buildings and facilities are fully depreciated or disposed.

Impairment of long-lived assets

Prior to January 1, 2005, the Company followed U.S. GAAP in accounting for impairment of long-lived assets for ROC GAAP purpose.

As discussed in Note 20, the Company reversed $5,641 thousand of impairment loss recognized in 2005 under ROC GAAP after a careful analysis of the increase in the estimated service potential of the production line facilities by an external specialist. Reversal the amount is prohibited under U.S. GAAP. As such, differences in the cost basis of these damaged machinery and equipment and associated depreciation expense between ROC and U.S. GAAP are reflected in the reconciliation.

Stock-based compensation

Under U.S. GAAP, stock-based compensation expense for the three months and nine months ended September 30, 2006 and 2007 includes compensation expense for all unvested stock-based compensation awards granted prior to January 1, 2006 that are expected to vest, based on the grant date fair value estimated in accordance with the transition method and the original provision of U.S. SFAS No. 123, “Accounting for Stock-Based Compensation” (“U.S. SFAS No. 123”). Upon an employee ’ s termination , unvested awards are forfeited, which affects the quantity of options to be included in the calculation of stock-based compensation expense. Forfeitures do not include vested options that expire unexercised. Stock-based compensation expense for all stock-based compensation awards granted after January 1, 2006 is based on the grant-date fair value estimate in accordance with the provisions of U.S. SFAS No. 123R, “Share-Based Payment” (“U.S. SFAS No. 123R”). The Company recognizes these compensation costs using the graded vesting method over the requisite service period of the award, which is generally the option vesting term of five years. Prior to the adoption of U.S. SFAS No. 123R, the Company recognized stock-based compensation expense in accordance with U.S. Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”). See Note 23d a further discussion on stock-based compensation.

Under ROC GAAP, employee stock option plans that are amended or have options granted on or after January 1, 2004 must be accounted for by the interpretations issued by the ARDF in Taiwan. The Company adopted the intrinsic value method and any compensation expense determined using this method is recognized over the vesting period. No stock-based compensation expense was recognized under ROC GAAP for the three months and nine months ended September 30, 2006 and 2007, respectively.

Goodwill

Effective January 1, 2006, the Company adopted ROC SFAS No. 25 (revised 2005), “Business Combinations-Accounting Treatment under Purchase Method” which is similar to U.S. SFAS No. 142. The Company ceased amortization and reviewed goodwill for impairment in accordance with the provisions of the standard and ROC SFAS No. 35.

Under U.S. GAAP, the Company adopted the provisions of U.S. SFAS No. 142 “Goodwill and Other Intangible Assets ” , on January 1, 2002. U.S. SFAS No. 142 requires the Company to review for possible impairment of goodwill existing at the date of adoption and perform subsequent impairment tests on at least an annual basis. In addition, existing goodwill and intangible assets must be reassessed and classified consistently in accordance with the criteria set forth in U.S. SFAS No. 141 and U.S. SFAS No. 142. As a result, the Company ceased to amortize goodwill effective January 1, 2002. Definite lived intangible assets will continue to be amortized over their estimated useful lives.

Undistributed earnings tax

In the ROC, a 10% tax is imposed on unappropriated earnings (excluding earnings from foreign consolidated subsidiaries). For ROC GAAP purposes, the Company records the 10% tax on unappropriated earnings in the year of shareholders’ approval. Starting from 2002, the American Institute of Certified Public Accountants International Practices Task Force (the “ Task Force ” ) concluded that in accordance with Emerging Issues Task Force (EITF) 95-10, “Accounting for tax credits related to dividends in accordance with SFAS 109,” the 10% tax on unappropriated earnings should be accrued under U.S. GAAP during the period the earnings arise and adjusted to the extent that distributions are approved by the shareholders in the following year.

Investments in parent company accounted for as treasury stock

Under ROC GAAP, shareholdings in the parent company are recorded as an available-for-sale financial asset and changes in fair value from a subsequent remeasurement are reported as a separate component of shareholders’ equity. Under U.S. GAAP, according to ARB No. 51 “Consolidated Financial Statements”, there is a presumption that the parent company must approve the subsidiary's transactions. Accordingly, unless this presumption can be overcome, the investment in the parent company's stock should be presented within the equity section of a wholly owned subsidiary's separate financial statements and be accounted for in the same manner as treasury stock. Upon the company’s receipt of cash dividend distributed by the parent company, the cash dividend should be recorded as additional paid-in capital.

Earnings per share

U.S. SFAS No. 128, “Earnings per share” provides guidance on applying the treasury stock method for equity instruments granted in share-based payment transactions in determining diluted earnings per share, which states that the assumed proceeds shall be the sum of (a) the exercise price, (b) the amount of compensation cost attributed to future services and not yet recognized, and (c) the amount of excess tax benefits that would be credited to additional paid-in capital assuming exercise of the options. Prior to January 1, 2006, the Company used the intrinsic value method to account for its stock-based compensation under both U.S. GAAP and ROC GAAP, resulting in no unrecognized compensation expense being included in the assumed proceeds calculation. However, upon adoption of U.S. SFAS No. 123R, the Company now has unrecognized compensation costs, and therefore, the number of diluted shares included in the diluted earnings per share calculation under U.S. GAAP will be different from that under ROC GAAP.

The following reconciles net income and shareholders’ equity under ROC GAAP as reported in the interim consolidated financial statements to the approximate net income and shareholders’ equity amounts as determined under U.S. GAAP, giving effect to adjustments for the differences listed above.

ADDITIONAL DISCLOSURES REQUIRED BY U.S. GAAP

Recently issued accounting standards

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

In September 2006, the FASB issued U.S. SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans—An Amendment of FASB Statements No. 87, 88, 106, and 132R” (U.S. SFAS No. 158). Provisions with respect to the recognition of an asset and liability related to the funded status and the changes in the funded status be reflected in comprehensive income are effective for fiscal years ending after December 15, 2006 and the change in measurement date provisions is effective for fiscal years ending after December 15, 2008. U.S. SFAS No. 158 also requires the measurement date of the plan’s funded status be the same as the Company’s fiscal year-end. The Company adopts all requirements of U.S. SFAS No. 158 on December 31, 2006. Upon the adoption of U.S. SFAS No. 158, the Company recognized a decrease to accumulative other comprehensive income of $1,712 thousand as of December 31, 2006.

In July 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 clarifies the accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before being recognized in the financial statements. It also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006 and is required to be adopted by the Company in fiscal 2007. The cumulative effects, if any, of applying FIN 48 will be recorded as an adjustment to retained earnings as of the beginning of the period of adoption. The Company is in the process of assessing FIN48 and the impact on the results of operations and financial position after the

adoption of FIN48 is inconclusive as of September 30, 2007.

Earnings per share

U.S. SFAS No. 128 requires the presentation of basic and diluted earnings per share. Basic net income per share is computed based on the weighted average number of common shares outstanding during the period. Diluted net income per share includes the effect of diluted equivalent common shares (stock options issued during the period using the treasury stock method).

Following is a reconciliation of denominators used in the basic and diluted computation:

	Three Months Ended September 30				Nine Months Ended September 30
	2006		2007		2006		2007
Weighted average shares, as adjusted
Basic		100,089,093		100,919,507		100,073,675		100,481,805
Effect of dilutive securities		52,996		2,306,543		53,950		2,076,812
Diluted		100,142,089		103,226,050		100,127,625		102,558,617

Diluted earnings per share exclude 10,339,713 and 10,338,759 anti-dilutive options for the three months and nine months ended September 30, 2006, respectively. Diluted earnings per share exclude 6,816,029 and 7,045,760 anti-dilutive options for the three months and nine months ended September 30, 2007, respectively. While these options were anti-dilutive for the respective periods, they could be dilutive in the future.

Stock option plans

Effective January 1, 2006, the Company adopted the fair value recognition provisions of U.S. SFAS No. 123R, using the modified prospective transition method and therefore has not restated results for prior periods. Under this transition method, stock-based compensation expense for the nine months ended September 30, 2006 and 2007 included stock-based compensation expense for all share-based payment awards granted prior to, but not yet vested as of January 1, 2006, based on the grant-date fair value estimated in accordance with the original provision of U.S. SFAS No. 123. In addition, the stock-based compensation expense also includes intrinsic value of certain outstanding share-based awards for which it was not possible to reasonable estimate their grant-date fair value under the requirement of U.S. SFAS No. 123. Stock-based compensation expense for all share-based payment awards granted after January 1, 2006 is based on the grant-date fair value estimated in accordance with the provision of U.S. SFAS No. 123R. The Company recognizes these compensation costs using the graded vesting method over the requisite service period of the award, which is generally a five-year vesting period. The adoption of U.S. SFAS No. 123R resulted in a cumulative gain from changes in accounting principle of $381 thousand, which reflects the net cumulative impact of estimating future forfeitures in the determination of period expense, rather than recording forfeitures when they occur as previously permitted. Prior to the adoption of U.S. SFAS No. 123R, the Company accounted for awards granted from ASE Inc. under the intrinsic value method prescribed by Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”), and related

interpretations, and provided the required pro forma disclosures prescribed by U.S. SFAS No. 123, as amended. In March 2005, SEC issued Staff Accounting Bulletin No. 107 (“SAB 107”) regarding SEC’s interpretation of U.S. SFAS No. 123R and the value of share-based payments for public companies. The Company has applied the provisions of SAB 107 in its adoption of U.S. SFAS No. 123R.

As a result of adopting U.S. SFAS No. 123R, income before income taxes and net income for the nine months ended September 30, 2006 were lower by $3,881 thousand and $2,911 thousand, respectively, than if the Company had continued to account for stock-based compensation under APB 25. The impact on both basic and diluted earnings per share for the nine months ended September 30, 2006 was a decrease of $0.03. In addition, prior to the adoption of U.S. SFAS No. 123R, the Company presented the tax benefit of stock option exercised as operating cash flows.

Information regarding ASE Test’s and ASE Inc’s stock option plans is as follows.

ASE Test Limited

ASE Test has three stock option plans, the 1999 Option Plan, the 2000 Option Plan and the 2004 Option Plan. Up to 2,000,000 shares, 12,000,000, and 2,500,000 shares have been reserved for issuance under the 1999, 2000 and 2004 option plans, respectively.

The 1999, 2000 and 2004 Option Plans granted the following stock options to purchase ASE Test’s shares which vest ratably over a period of five years from the date of grant until the expiration of options, to directors, officers and key employees. If any granted shares are forfeited, the shares may be granted again, to the extent of any such forfeiture.

ASE Inc.

ASE Inc., the parent company, has two option plans, the 2002 Option Plan and the 2004 Option Plan. The maximum number of units authorized to be granted under the 2002 and 2004 option plan is 160 million and 140 million, respectively, with each unit representing one share of ASE Inc. Under the terms of the plans, stock option rights are granted to employees, including those of the Company, which have an exercise price equal to the closing price of the ASE Inc. common stock as per the Taiwan Stock Exchange on the date of grant, and such exercise price is subject to retroactive adjustment in the event of certain capital transactions in subsequent periods. The option rights expire ten years from the date of grant. On the second anniversary of the grant date, 40% of the options become vested and the remaining options vest ratably over a period of three years thereafter. Under the 2002 and 2004 Option Plans, 41,603,100 and 28,499,550 units were granted, respectively, by ASE Inc. to employees of the Company.

Information regarding the options issued to employees of the Company under ASE Inc.’s stock option plan for the Company is as follows (in U.S. dollars):

The 2002 option plan is accounted for as a variable plan, as a result of a provision in the plan which would require an adjustment of the exercise price in accordance with a prescribed formula based on occurrence of certain future events. Accordingly, no adjustment is required for purposes of the pro forma compensation expense calculated in accordance with U.S. SFAS No. 123 before January 1, 2006 for these options. Upon the adoption of U.S. SFAS No. 123R, the Company continued to account for these stock options based on its intrinsic value, and remeasured at each reporting date through the date of exercise or other settlement.

The fair value of the option plan issued was determined using a Black-Scholes option pricing model with the following assumptions:

Risk-free interest rate		1.80%-2.50%
Expected life		5 years
Expected dividend		3.00%
Expected volatility		47%-59%

Appendix K

The following is the form of opinion to be provided by ANZ Singapore Limited in relation to the scheme:

ANZ SINGAPORE LIMITED

(Incorporated in the Republic of Singapore)

Company Registration Number: 198602937W

_____ 2008

The Independent Directors of

ASE Test Limited

[ ]

Dear Sirs

PROPOSED ACQUISITION OF ALL THE ISSUED SHARES OF ASE TEST LIMITED BY ADVANCED SEMICONDUCTOR ENGINEERING, INC. BY WAY OF A SCHEME OF ARRANGEMENT UNDER SECTION 210 OF THE COMPANIES ACT, CHAPTER 50 OF SINGAPORE.

For the purpose of this letter, capitalized terms not otherwise defined shall have the meaning given to them in the scheme document to be circulated to the shareholders of ASE Test (the “ Scheme Document ”).

1. INTRODUCTION

On 4 September 2007 (the “ Joint Announcement Date ”), each of ASE Test Limited (“ ASE Test ” or the “ Company ”) and Advanced Semiconductor Engineering, Inc. (the “ Acquiror ” or “ ASE Inc. ”) (each a “ Party ”, and collectively, the “ Parties ”), jointly announced that ASE Test and ASE Inc. have executed a scheme implementation agreement (the “ Scheme Implementation Agreement ”) to privatize ASE Test by way of a scheme of arrangement (the “ Scheme ”) under Section 210 of the Companies Act, Chapter 50 of Singapore (the “ Companies Act ”) and in accordance with the Singapore Code on Take-Overs and Mergers (the “ Code ”).

ASE Test is incorporated in the Republic of Singapore. Certain of the ordinary shares in the share capital of ASE Test are listed and quoted on The NASDAQ Global Market, Inc. (" NASDAQ "; such shares, " ASE Test NASDAQ Shares ") and the remaining ordinary shares in the share capital of ASE Test are represented by ASE Test Taiwan Depository Shares (" ASE Test TDSs ", and together with the ASE Test NASDAQ Shares, the " ASE Test Shares ") which are listed and quoted on the Taiwan Stock Exchange (" TSE ").

According to the terms of the Scheme Implementation Agreement, upon the effectiveness of the Scheme, ASE Test NASDAQ Shares will be acquired by ASE Inc. for US$14.78 per share in cash, and ASE Test TDSs will be acquired by ASE Inc. for the NT$ equivalent of US$0.185 per share in cash (based on the prevailing exchange rate calculated in the manner described on page [ · ] of the accompanying scheme document). ASE Inc. indirectly holds approximately 50.34 per cent. of ASE Test’s outstanding ordinary shares as at 31 October 2007. If the Scheme becomes effective, ASE Test will become an indirect wholly-owned subsidiary of ASE Inc., and the ASE Test NASDAQ Shares and ASE Test TDSs will be delisted from the NASDAQ and the TSE, respectively.

This letter sets out, inter alia , our opinion on the fairness of the Scheme Consideration from a financial point of view to the shareholders of ASE Test (other than ASE Inc. and its subsidiaries) (the “ Scheme Shareholders ”). It will form part of the Scheme Document issued by the Company providing, inter alia , the details of the Scheme and the recommendations of the directors of the Company who are considered independent for the purposes of the Scheme to the Scheme Shareholders. Unless otherwise defined or the context otherwise requires, all terms defined in the Scheme Document shall have the same meaning herein.

2. TERMS OF REFERENCE

ANZ has been engaged to provide an independent financial adviser opinion to the directors of ASE Test who are considered independent for the purposes of the Scheme, namely, Mr Albert C.S. Yu, Mr Sim Guan Seng and Mr David D.H. Tsang (the “ Independent Directors ”) in relation to the Scheme Consideration to be paid to the Scheme Shareholders in connection with the Scheme.

We make no representations or warranties in relation to the merits of the Scheme other than to form an opinion for the purposes of Rule 7.1 of the Code. We have limited our evaluation to the financial terms of the Scheme and have not commented, evaluated, or taken into account the commercial risks or commercial merits of the Scheme. Our terms of reference do not require us to evaluate or comment on the strategic or long-term commercial merits of the Scheme or on the prospects of ASE Test or any of its respective related companies (as defined in the Companies Act of Singapore). Such evaluations or comments remain the responsibility of the directors and management of ASE Test. However, we may draw upon the views of the directors and management of ASE Test in arriving at our view. We were also not requested or authorised to solicit any indications of interest from any third party with respect to the Scheme (an “ Alternative Offer ”). We are not addressing the relative merits of the Scheme as compared to any alternative transaction that ASE Test may have previously considered or otherwise may become available to ASE Test (or its shareholders) in the future, or as compared to any Alternative Offer that might otherwise be available.

We were neither a party to the negotiations entered into by ASE Test in relation to the Scheme nor were we involved in the discussions leading up to the decision on the part of the Board of Directors of ASE Test (with the Independent Directors voting and the non-independent directors abstaining from voting) to enter into the Scheme Implementation Agreement.

We have held discussions with the Independent Directors and management of ASE Test and have examined information provided by the Independent Directors and management of ASE Test and certain publicly available information collected by us, upon which our opinion is based. We have not independently verified such information, whether written or verbal, and accordingly cannot and do not make any representation or warranty in respect of, and do not accept any responsibility for, the accuracy, completeness or adequacy of such information.

We have relied upon the assurances of the Directors of ASE Test made pursuant to the “Responsibility Statements” section set out in this Scheme Document that the Directors of ASE Test (including any Director of ASE Test who has delegated detailed supervision of the Scheme Document) have taken all reasonable care to ensure that the facts stated and opinions expressed in this Scheme Document are fair and accurate and that no material facts have been omitted from this Scheme Document. The Directors of ASE Test jointly and severally accept responsibility accordingly

We have not made an independent evaluation or appraisal of the assets and liabilities of ASE Test and we have not been furnished with any such evaluation or appraisal valuation reports in respect of the assets held by ASE Test and its subsidiaries nor have we evaluated the solvency of the Company under any applicable laws relating to bankruptcy, insolvency or similar matters.

Accordingly, no representation or warranty, express or implied, is made and no responsibility is accepted by us concerning the accuracy, completeness or adequacy of all information, provided or otherwise made available to us or relied on by us as described above.

Furthermore, our terms of reference do not require us to express, and we do not express, an opinion on the future growth prospects of ASE Test and its subsidiaries, or any of its respective related or associated companies. We are therefore not expressing any opinion herein as to the future financial or other performance of those companies.

Our opinion, as set out in this letter, is based upon the market, economic, industry, monetary and other applicable conditions subsisting on, and the information made available to us, as of (the “ Latest Practicable Date ”). We assume no responsibility to update, revise or reaffirm our opinion in the light of any subsequent development after the Latest Practicable Date that may in any way affect our opinion contained herein. Shareholders of ASE Test should take note of any announcement relevant to their consideration of the Scheme which may be released by or on behalf of the Company or the Acquiror after the Latest Practicable Date.

We have relied upon certain estimates of financial results for the 2007 calendar year which have been provided to us by the management of ASE Test. We have not independently verified such information, whether written or verbal, and accordingly cannot and do not make any representation or warranty in respect of, and do not accept any responsibility for, the accuracy, completeness or adequacy of such information. We have nevertheless made enquiries in assessing such information and are not aware of any reason to doubt the information has been prepared with due and careful enquiry.

In rendering our advice and giving our recommendation, we have not had regard to the specific investment objectives, financial situation, tax position or individual circumstances of any Scheme Shareholder. As different Scheme Shareholders would have different investment objectives and profiles, we would advise the Independent Directors to recommend that any individual Scheme Shareholder who may require specific advice in relation to his investment portfolio should consult his stockbroker, bank manager, solicitor, accountant, tax adviser or other professional advisers.

We have also assumed that the transactions contemplated by the Scheme Implementation Agreement will be consummated as described therein and will not differ in any material respect from the Scheme Implementation Agreement. We have further assumed that all material government, regulatory and other consents and approvals necessary for the consummation of the transactions contemplated by the Scheme Implementation Agreement will be obtained without any adverse effect on the Company.

Our opinion in relation to the Scheme should be considered in the context of the entirety of this letter and this Scheme Document.

General information on the Company is set out on pages [ ] of the Scheme Document.

7. FINANCIAL ASSESSMENT OF THE SCHEME

In evaluating the fairness of the Scheme Consideration, from a financial point of view, as at the Latest Practicable Date, we have considered the following factors:

(A)	Valuation multiples of broadly comparable companies of ASE Test;

(B)	Transaction multiples implied by the privatization of United Test and Assembly Center Ltd. (“ UTAC ”) by Affinity Equity Partners and TPG Capital;

(C)	Selected precedent completed and pending privatizations of companies listed on the NASDAQ;

(D)	Price performance of the ASE Test shares; and

(E)	Other considerations.

(A) Valuation multiples of broadly comparable companies of ASE Test

We recognise that there are no listed companies comparable to ASE Test in terms of composition of business activities, scale of operations, geographical spread of activities, track record, future prospects and other relevant criteria.

However, reference can be made to listed companies that are considered broadly comparable to ASE Test to provide an indication of the current market expectations with regard to the valuation of these businesses.

Accordingly, for our evaluation, we have considered:

(i)

Enterprise Value (“ EV ”) to Earnings Before Interest, Taxes, Depreciation and Amortisation (“ EBITDA ”) for the last twelve months and normalized by eliminating non-recurring items (“ EV / LTM EBITDA ”). EV is calculated by adding short- and long-term debt to the sum of the market value of common equity, intrinsic value of all in-the-money stock options and the book value of any minority interest, and subtracting cash and cash equivalents, including marketable securities;

(ii)	EV to Earnings Before Interest and Taxes (“ EBIT ”) for the last twelve months and normalized by eliminating non-recurring items (“ EV / LTM EBIT ”);

(iii)

Price to Earnings Per Share Ratio for the last twelve months and normalized by eliminating non-recurring items (“ LTM PER ”);

(iv)	EV to consensus EBITDA estimates for fiscal year 2007 (“ E V / FY07E EBITDA ”) ;

(v)	EV to consensus EBIT estimates for fiscal year 2007 (“ E V / FY07E EBIT ”) ;

(vi)	Consensus PER estimates for fiscal year 2007 (“ FY07E PER ”) ; and

(vii)

Price to Net Tangible Assets per Share (“ Price / NTA ”).

For the purposes of evaluating the scheme, EBITDA has been defined as operating income before depreciation and amortization. This definition of EBITDA differs slightly from the EBITDA that has been previously reported by ASE Test, which is calculated based on net income before taxes, net interest and other financing costs, depreciation and amortization, and income from long-term investments. The calculation of EBITDA (as defined above for purposes of evaluating the scheme) eliminates the effect of any non-operating income and expenses and serves as an indicator of the ability of ASE Test and the comparable companies to generate cash flows from their operations. In addition, for the purpose of evaluating the scheme, EBIT has been defined as operating income as such operating income has previously been reported by ASE Test and the comparable companies, respectively. The calculations of EBIT (as defined above for purposes of evaluating the scheme) eliminates the effect of any non-operating income and serves as an indicator of the ability of ASE Test and the comparable companies to generate earnings from their operations.

Based on our research, and after discussions with the management of ASE Test, we are of the view that the listed semiconductor companies, set out in the table below, may be considered to be broadly comparable to ASE Test. The companies have been grouped into large capitalization companies (defined in this case as companies with an EV of greater than US$2 billion) which derive more than 50 per cent. of their revenues from packaging services and medium capitalization companies (defined in this case as companies with an EV of less than US$2 billion) which derive more than 50 per cent. of their revenues from test services. On this basis ASE Test is a medium capitalization company which derives more than 50 per cent. of its revenues from test services. The Independent Directors should note that any comparison made with respect to the selected companies considered to be broadly comparable to ASE Test serves as an illustrative guide only. The Independent Directors should note that as of the Latest Practicable Date and to our knowledge, none of the broadly comparable companies are the subject of a takeover offer or take private transaction.

For illustrative purposes only, the EV / EBITDA, EV / EBIT, PER multiples of broadly comparable companies on both an LTM basis and FY07E basis (based on their last transacted prices as at the Latest Practicable Date) and ASE Test (based on the Scheme Consideration) are set out in the table below.

In addition, the Independent Directors also should bear in mind that the NTA basis of valuation is only meaningful insofar as it indicates the extent to which the value of each share is backed by tangible assets, and would be relevant in the event that ASE Test decides to change the nature of its business or to release or convert the uses of all its assets. The NTA basis of valuation does not necessarily reflect the value of ASE Test as a going concern.

Notes:

(1)	Market capitalization calculated based on the closing price as at the Latest Practicable Date and diluted shares outstanding (treasury method). ASE Test’s market capitalization is calculated based on the Scheme Consideration and diluted shares outstanding (treasury method).

(2)	Market capitalization and enterprise values have been converted to US$ based on the relevant spot exchange rates as at the Latest Practicable Date.

(3)	LTM EBITDA, LTM EBIT, LTM PER and Price / NTA based on latest 12-month results sourced from the latest available quarterly and annual reports and have been normalized to eliminate non-recurring items.

(4)	FY07E EBITDA, FY07E EBIT and FY07E PER are based on Bloomberg Consensus Earnings Estimates.

(5)	Siliconware Precision Industries Co. Ltd. and King Yuan Electronics Co. Ltd. are based on financial statements for 12 months ended 30 June 2007.

(6)	LTM and FY07E EBITDA, EBIT and Net Income for ASE Inc., Siliconware Precision Industries Co. Ltd and ChipMOS Technologies (Bermuda) Ltd have been adjusted for employee option expense, estimated based on respective companies’ FY06 annual reports, in order to align with US GAAP.

(7)

ASE Test’s EV is calculated based on the Scheme Consideration and includes 30 per cent. of ASE Korea’s debt and cash, and the value of ASE Test’s shareholding in ASE Inc. which was treated as marketable securities and was calculated at a 3 per cent. discount to the market price of ASE Inc. common shares as of the Latest Practicable Date. ASE Test’s LTM and FY07E EBITDA, EBIT and Net Income include ASE Test’s 30 per cent. share of ASE Korea and has been adjusted for employee option expense, based on estimates of ASE Test’s management.

For illustrative purposes only based on the Scheme Consideration and the table above:

1.	the EV / LTM EBITDA and EV / FY07E EBITDA of ASE Test exceed both the mean and median EV / LTM EBITDA and EV / FY07E EBITDA multiples of the selected broadly comparable medium capitalization companies;

2.	the EV / LTM EBIT and EV / FY07E EBIT of ASE Test exceed both the mean and median EV / LTM EBIT and EV / FY07E EBIT multiples of the selected broadly comparable medium capitalization companies;

3.	the LTM PER and FY07E PER of ASE Test exceed both the mean and median LTM PER and FY07E PER multiples of the selected broadly comparable medium capitalization companies; and

4.	the Price / NTA of ASE Test exceeds both the mean and median Price / NTA of the selected broadly comparable medium capitalization companies.

We note that none of the broadly comparable companies is currently the subject of a takeover or going private transaction. In this regard in section (B) below, we have reviewed the transaction multiples in connection with the going private transaction completed in October 2007 via a scheme of arrangement in Singapore involving UTAC, a broadly comparable medium capitalization company to ASE Test.

In addition, in section (C) below we have also considered premia to historical trading prices for selected companies listed on NASDAQ that were subject to going private transactions where the unaffiliated shareholders held less than 50 per cent. of the total ordinary shares in the company subject to the going private transaction. In this regard, the mean and median premia over the last traded price prior the respective announcement date for the selected going private transactions were 20.5 per cent. and 15.8 per cent, respectively. If these premia were applied to the multiples of the broadly comparable medium capitalization companies above, the observations at 1, 2 and 3 above would generally continue to apply and the Price / NTA of ASE Test would be in line with the mean and median Price / NTA of the selected broadly comparable medium capitalization companies.

(B) Transaction multiples implied by the privatization of UTAC

The privatization of UTAC by Affinity Equity Partners and TPG Capital, which was completed in October 2007, is the most recent and relevant transaction in the semiconductor packaging and testing industry that has been publicly announced as at the Latest Practicable Date. UTAC and ASE Test derive the majority of their respective revenues from testing services and are similar in terms of market capitalization.

We recognize that the privatization of UTAC was a leveraged buy-out transaction, where the acquiror did not have any equity interest prior to the announcement of the offer.

For illustrative purposes only, the EV / EBITDA, EV / EBIT, PER multiples of UTAC (based on the scheme consideration price of S$1.20 per UTAC share – sourced from UTAC’s scheme document) and ASE Test (based on the Scheme Consideration) on both an LTM basis and FY07E basis are set out in the table below.

Source: Bloomberg, Annual Reports, Quarterly Reports, ASE Test Management’s estimates and UTAC’s Scheme Document.

Notes:

(1)	UTAC’s market capitalization is sourced from UTAC’s Scheme Document. ASE Test’s market capitalization is calculated based on the Scheme Consideration and diluted shares outstanding (treasury method).

(2)	LTM EBITDA, LTM EBIT, LTM PER and Price / NTA based on latest 12-month results sourced from the latest available quarterly and annual reports and have been normalized to eliminate non-recurring items.

(3)	FY07E EBITDA, FY07E EBIT and FY07E PER are based on Bloomberg Consensus Earnings Estimates.

(4)

ASE Test’s EV is calculated based on the Scheme Consideration and includes 30 per cent. of ASE Korea’s debt and cash, and the value of ASE Test’s shareholding in ASE Inc. which was treated as marketable securities and was calculated at a 3 per cent. discount to the market price of ASE Inc. common shares as of the Latest Practicable Date. ASE Test’s LTM and FY07E EBITDA, EBIT and Net Income include ASE Test’s 30 per cent. share of ASE Korea and adjusted for employee option expense, based on estimates of ASE Test’s management.

For illustrative purposes only based on the Scheme Consideration and the table above:

1.	the EV / LTM EBITDA and EV / FY07E EBITDA of ASE Test are marginally below the EV / LTM EBITDA and EV / FY07E EBITDA multiples of the privatization of UTAC;

2.	the EV / LTM EBIT and EV / FY07E EBIT of ASE Test are marginally below the EV / LTM EBIT and EV / FY07E EBIT multiples of the privatization of UTAC;

3.	the LTM PER of ASE Test is marginally below the LTM PER multiple of the privatization of UTAC but the FY07E PER of ASE Test exceeds the FY07E PER multiple of the privatization of UTAC; and

4.	the Price / NTA of ASE Test is below the Price / NTA multiple of the UTAC privatization.

As highlighted above, the privatization of UTAC was a leveraged buy-out transaction involving a change of control. In contrast, ASE Inc. indirectly holds a controlling interest of approximately 50.34 per cent. of ASE Test's outstanding ordinary shares as at 31 October 2007. In this regard, the pricing may not be directly comparable to the UTAC privatization which may have reflected a premium to effect a change of control which may not necessarily be paid to privatize a company where the acquiror already has control by holding shares bearing more than 50 per cent. of the outstanding voting rights. We further note that the UTAC privatization was announced prior to the instability in equity markets arising from various announcements of significant defaulting sub-prime loans in the United States that began in late July 2007. Taking each of these factors into account, the valuation multiples implied by the Scheme Consideration may be considered to be generally comparable to the transaction multiples implied by the privatization of UTAC.

(C) Selected precedent completed and pending privatizations of companies listed on the NASDAQ

We have reviewed selected precedent completed and pending privatizations of companies listed on the NASDAQ where the shareholders of the company subject to privatisation unaffiliated with the acquiror held less than 50 per cent. of the outstanding share capital, the deal value was greater than US$100 million, and the privatization consideration was 100 per cent. paid in cash.

For each transaction, we have considered the premium or discount implied by the offer price to the last traded price before its respective announcement date and to the average price during the 7-day, 30-day and 90-day period prior to its respective announcement date.

Source: Bloomberg .

Notes:

(1)	Offer price based on the final bid price per share.

(2)	Last traded price before the announcement date of the transaction.

(3)	Average price of shares traded during the specified number of trading days prior to announcement date of the transaction calculated using Bloomberg;

(4)	Outcome of transaction pending as at the Latest Practicable Date.

For illustrative purposes only based on the table above, the premia implied by the Scheme Consideration:

(i)	exceed the mean and median premia over the last traded price prior to the respective announcement date for the selected privatization transactions;

(ii)	exceed the mean and median premia over the 7-day average price for the selected privatization transactions;

(iii)

exceed the mean and median premia over the 30-day average price for the selected privatization transactions; and

(iv)	is below the mean and median premia over the 90-day average price for the selected privatization transactions.

The Independent Directors should note that the level of premium (if any) an acquiror would normally pay in a merger or takeover transaction will vary in different circumstances depending, inter alia , on the attractiveness of the underlying business to be acquired, the synergies to be gained from integration with an existing business to be acquired, the possibility of realization of any significant revaluation of the assets to be acquired, the availability of substantial cash reserves, the liquidity in the trading of the target company’s shares, the presence of competing bids for the target company, the form of consideration offered by the acquiror, the extent of control the acquiror already has in the target company and prevailing market expectations.

The Independent Directors should further note that the comparison is made without taking into consideration the relative efficiency of information, the underlying liquidity of the shares of the relevant companies, the performance of the shares of the companies, the quality of earnings prior to the relevant announcement and the market conditions or sentiments when the announcements were made or the desire or relative need for control leading to compulsory acquisition.

Moreover, as ASE Test is not in the same industry and does not conduct the same businesses as the other target companies in the precedent privatization transactions, it may not, therefore, be directly comparable to the target companies in terms of composition of business activities, product lines, scale of operations, risk profile, geographical spread of activities, client base, accounting policies, track record, prospects and other relevant criteria. Accordingly, the Independent Directors should note that the above comparison is for illustrative purposes and serves as a general guide only.

(8)	4 Aug 07: ASE Test released 2Q07 results; net income (US GAAP) declined 54 per cent. from the previous corresponding period.

(9)	4 Sep 07: Joint Announcement Date.

We have considered whether current and historical share prices of ASE Test are reasonable indicators for assessing the financial value of the shares at a given point in time. Under ordinary circumstances, the market valuation of shares traded on a recognised stock exchange may be affected by, inter alia , its

relative liquidity, the size of its free float, the extent of research coverage and investor interest it attracts, and the general market sentiment at a given point in time.

The Independent Directors should note that as at 31 October 2007, the Company had a free float of approximately 48.2 per cent calculated based on those ASE Test shareholders other than ASE Inc, its affiliates and the directors of ASE Test and ASE Inc. who own ASE Test Shares. The Independent Directors should further note that ASE Test NASDAQ Shares’ average daily trading volume on the NASDAQ was approximately 306,841 ordinary shares per day during the 12 months preceding the Joint Announcement Date representing approximately 0.6 per cent. of the free float. For ASE Test TDSs, average daily trading volume on the TSE is approximately 174,391 ordinary shares (adjusted based on the 1:80 NASDAQ Share / TDS ratio) per day during the 12 months preceding the Joint Announcement Date representing approximately 0.4 per cent. of the free float.

Notes:

(1)	Based on 101,028,341 ASE Test Shares outstanding as at the Joint Announcement Date. Free float excludes ASE Inc.’s shareholding of 50,985,143 ASE Test Shares and the shareholdings of Affiliated Directors of 1,450,032 ASE Test Shares as at the Joint Announcement Date.

Based on the above, the trading volumes of ASE Test Shares appear to be relatively low.

The Scheme Consideration represents a 25.6 per cent. premium over the last traded price of ASE Test NASDAQ Shares on the last trading day prior to the Joint Announcement Date and a premium over the Volume Weighted Average Price (“ VWAP ”) per ASE Test NASDAQ Shares over the 30-day, 60-day, 90-day and 180-day periods preceding the Joint Announcement Date; whereas the Scheme Consideration represents a small discount to the VWAP over the 60-day and 90-day periods per ASE Test TDSs.

(2)	VWAP is based on the daily volume and closing price of the relevant instrument for the specified number of trading days.

The price of ASE Test NASDAQ Shares has been compared with the NASDAQ Composite Index (“ NASDAQ Composite ”), the Philadelphia Stock Exchange Semiconductor Index (“ Semiconductor Index ”) and Comparable Companies Index (“ Comparables Index ”) for the 12 month period prior to the Joint Announcement Date up to the Last Practicable Date. This is depicted in the chart below.

(2)

Companies within the Comparables Index include ASE Inc., Siliconware Precision Industries Co. Ltd, Amkor Technology Inc, STATS ChipPAC Ltd, Powertech Technologies Inc, King Yuan Electronics Co. Ltd, Greatek Electronics Inc, ChipMOS Technologies (Bermuda) Ltd. Each company is weighted based on its daily market capitalization in the Comparables Index.

The table below summarises the movement in ASE Test NASDAQ Share price and the three indices identified above during the period starting from 1 September 2006, being one full year prior to the Joint Announcement Date, to 31 August 2007, the last full trading day of ASE Test NASDAQ Shares on the NASDAQ prior to the Joint Announcement Date.

Based on both the chart and table above, the ASE Test NASDAQ Share price has underperformed against the Comparables Index and has outperformed against the NASDAQ Composite and the Semiconductor Index.

The table below summarises the movement in the ASE Test NASDAQ Share price and the three indices identified above during the period starting from 1 September 2006, being one full year prior to the Joint Announcement Date, to the Latest Practicable Date.

Based on the movement of the ASE Test NASDAQ Share price, the NASDAQ Composite, the Semiconductor Index and the Comparables Index over the aforesaid period, the ASE Test NASDAQ Share price has outperformed the overall applicable market (as reflected by the aforementioned indices) from 1 September 2006 to the Latest Practicable Date.

The past trading performance of ASE Test NASDAQ Shares should not in any way be relied upon as an indication of the future trading performance of ASE Test Shares.

(E) Other considerations

We have considered th e possibility of an alternative offer from a third party for a consideration that is significantly above the terms of the Scheme proposed by ASE Inc , but as at the Latest Practicable Date, there is no publicly available evidence of such an alternative offer for the ASE Test Shares from any third party.

8. RECOMMENDATION

Based upon and having considered the information that has been made available to us and the above factors set forth in this letter, we are of the opinion that, as at the Latest Practicable Date, from a financial point of view, having taken into consideration, inter alia , the following:

(i)	ASE Test’s EV / LTM EBITDA and EV / FY07E EBITDA as implied by the Scheme Consideration exceed both the mean and median EV / LTM EBITDA and EV / FY07E EBITDA multiples of the selected broadly comparable medium capitalization companies;

(ii)	ASE Test’s EV / LTM EBIT and EV / FY07E EBIT as implied by the Scheme Consideration exceed both the mean and median EV / LTM EBIT and EV / FY07E EBIT multiples of the selected broadly comparable medium capitalization companies;

(iii)

ASE Test’s LTM PER and FY07E PER as implied by the Scheme Consideration exceed both the mean and median LTM PER and FY07E PER multiples of the selected broadly comparable medium capitalization companies;

(iv)	ASE Test’s Price / NTA as implied by the Scheme Consideration exceeds both the mean and median Price / NTA multiples of the selected broadly comparable medium capitalization companies;

(v)

the price of ASE Test NASDAQ Shares for the 12 month period prior to the Joint Announcement Date up to 31 August 2007, the last full trading day of ASE Test NASDAQ Shares on the NASDAQ prior to the Joint Announcement Date, had outperformed against the NASDAQ Composite and the Semiconductor Index, and underperformed against the Comparables Index. Following the announcement of the Scheme we also note that the price of ASE Test NASDAQ Shares for the 12 month period prior to the Joint Announcement Date up to the Latest Practicable Date, had outperformed against the NASDAQ Composite, the Semiconductor Index and the Comparables Index;

(vi)

the Scheme Consideration represents a 25.6 per cent. premium to the last transacted price of ASE Test NASDAQ Shares on the NASDAQ of US$11.77 as of August 31, 2007, the last full trading day of ASE Test NASDAQ Shares on the NASDAQ prior to the Joint Announcement Date. It is also a premium to the VWAP on ASE Test NASDAQ Shares over the 30-day, 60-day, 90-day and 180-day periods preceding the Joint Announcement Date, except in the case of ASE Test TDSs where the Scheme Consideration represents a small discount to the VWAP over the 60-day and 90-day periods per ASE Test TDSs;

(vii)

the premium implied by the Scheme Consideration, exceeds the mean and median of the premia to the last traded price before the respective announcement dates and the 7-day, 30-day average prices of the selected privatizations but is below the mean and median of the premia to the 90-day average prices of such selected privatizations;

(viii)

the valuation multiples implied by the Scheme Consideration may be considered to be generally comparable to the transaction multiples implied by the privatization of UTAC;

(ix)	the trading volumes of ASE Test Shares appear to be relatively low; and

(x)	as of the Latest Practicable Date, there is no publicly available evidence of an alternative offer for ASE Test Shares from any third party for a consideration that is above the terms of the Scheme as proposed by ASE Inc.,;

the Scheme Consideration is fair from a financial point of view to the Scheme Shareholders.

We would further highlight that our opinion is limited to the fairness of the Scheme Consideration from a financial point of view and we are not advising as to the future business and prospects of the Company.

Our opinion as disclosed in this letter, is based upon the market, economic, industry, monetary and other applicable conditions subsisting on, and the information made available to us as of, the Latest Practicable Date.

This opinion is addressed to the Independent Directors for their benefit, in connection with, and for the purpose of, their consideration of the Scheme provided, that a copy of this opinion may be included in its entirety in the Scheme Document and in any filings that ASE Test is required to make with U.S. Securities and Exchange Commission (or any other filings to be specifically agreed by ANZ) in connection with the Scheme. Our terms of reference do not require us to express, and we do not express, an opinion on the future growth prospects of the Company. This opinion does not constitute, and should not be relied on as a recommendation to, or confer any rights upon, any shareholder of ASE Test as to how to vote in relation to the Scheme or any matter related thereto. The recommendation to be made by the Independent Directors to Shareholders shall remain the responsibility of the Independent Directors.

The Independent Directors should note that the trading of ASE Test Shares is subject to, inter alia , the performance and prospects of ASE Test and its subsidiaries and affiliates, prevailing market conditions, economic outlook and stock market conditions and sentiments. Accordingly, this opinion does not and cannot take into account future trading activities, patterns or price levels that may be established for the ASE Test Shares after the Latest Practicable Date since these are governed by factors beyond the ambit of our review and also, this opinion, if given, would not fall within our terms of reference in connection with the Scheme.

This opinion is governed by, and construed in accordance with, the laws of Singapore, and is strictly limited to the matters stated herein and does not apply by implication to any other matter. Nothing herein shall confer or be deemed or is intended to confer any right or benefit to any third party and the Contracts (Rights of Third Parties) Act, Chapter 53B of Singapore shall not apply.

Yours faithfully

For and on behalf of

ANZ Singapore Limited

Appendix L

Rights of ASE Test Shareholders in Respect of Voting, Dividends and Capital

Set forth below are excerpts from the relevant portions of the Articles of Association of ASE Test relating to the rights of ASE Test shareholders in respect of voting, dividends and capital:

(a)	Rights in respect of voting

“53.

No business shall be transacted at any General Meeting unless a quorum is present at the time when the meeting proceeds to business. Save as herein otherwise provided, the quorum at any General Meeting shall be members holding in aggregate not less than 33 1/3 per cent. of the total issued and fully paid shares in the capital of the Company for the time being, present in person or by proxy. For the purpose of this Article, “Member” includes a person attending by proxy or by attorney or as representing a corporation which is a Member.

63.

Subject and without prejudice to any special privileges or restrictions as to voting for the time being attached to any special class of shares for the time being forming part of the capital of the Company each member entitled to vote may vote in person or by proxy. On a show of hands every member who is present in person and each proxy shall have one vote and on a poll, every member who is present in person or by proxy shall have one vote for every share which he holds or represents.

64.

In the case of joint holders of a share the vote of the senior who tenders a vote, whether in person or by proxy, shall be accepted to the exclusion of the votes of the other joint holders and for this purpose seniority shall be determined by the order in which the names stand in the Register of Members in respect of the share.

65.

Where in Singapore or elsewhere a receiver or other person (by whatever name called) has been appointed by any court claiming jurisdiction in that behalf to exercise powers with respect to the property or affairs of any member on the ground (however formulated) of mental disorder, the Directors may in their absolute discretion, upon or subject to production of such evidence of the appointment as the Directors may require, permit such receiver or other person on behalf of such member to vote in person or by proxy at any General Meeting or to exercise any other right conferred by membership in relation to meetings of the Company.

66.

No member shall, unless the Directors otherwise determine, be entitled in respect of shares held by him to vote at a General Meeting either personally or by proxy or to exercise any other right conferred by membership in relation to meetings of the Company if any call or other sum presently payable by him to the Company in respect of such shares remains unpaid.

67.

No objection shall be raised as to the admissibility of any vote except at the meeting or adjourned meeting at which the vote objected to is or may be given or tendered and every vote not disallowed at such meeting shall be valid for all purposes. Any such objection shall be referred to the chairman of the meeting whose decision shall be final and conclusive.

68.

On a poll, votes may be given either personally or by proxy and a person entitled to more than one vote need not use all his votes or cast all the votes he uses in the same way.

69.

(A)

A member may appoint any number of proxies to attend and vote at the same General Meeting.

(B)

The Company shall be entitled and bound, in determining rights to vote and other matters in respect of a completed instrument or proxy submitted to it, to have regard to the instructions (if any) given by and the notes (if any) set out in the instrument of proxy.

(C)

In any case where a form of proxy appoints more than one proxy, the proportion of the shareholding concerned to be represented by each proxy shall be specified in the form of proxy.

(D)

A proxy need not be a member of the Company.

70.

(A)

An instrument appointing a proxy shall be in writing in any usual or common form or in any other form which the Directors may approve and:-

(a)

in the case of an individual shall be signed by the appointor or his attorney; and

(b)

in the case of a corporation shall be either given under its common seal or signed on its behalf by an attorney or a duly authorised officer of the corporation.

(B)

The signature on such instrument need not be witnessed. Where an instrument appointing a proxy is signed on behalf of the appointor by an attorney, the letter or power of attorney or a duly certified copy thereof must (failing previous registration with the Company) be lodged with the instrument of proxy pursuant to the next following Article, failing which the instrument may be treated as invalid.

71.

An instrument appointing a proxy must be left at such place or one of such places (if any) as may be specified for that purpose in or by way of note to or in any document accompanying the notice convening the meeting (or, if no place is so specified, at the Office) not less than forty-eight hours before the time appointed for the holding of the meeting or adjourned meeting or (in the case of a poll taken otherwise than at or on the same day as the meeting or adjourned meeting) for the taking of the poll at which it is to be used, and in default shall not be treated as valid. The instrument shall, unless the contrary is stated thereon, be valid as well for any adjournment of the meeting as for the meeting to which it relates; Provided that an instrument of proxy relating to more than one meeting (including any adjournment thereof) having once been so delivered for the purposes of any meeting shall not require again to be delivered for the purposes of any subsequent meeting to which it relates.

72.

An instrument appointing a proxy shall be deemed to include the right to demand or join in demanding a poll, to move any resolution or amendment thereto and to speak at the meeting.

73.

A vote cast by proxy shall not be invalidated by the previous death or insanity of the principal or by the revocation of the appointment of the proxy or of the authority under which the appointment was made provided that no intimation in writing of such death, insanity or revocation shall have been received by the Company at the Office at least one hour before the commencement of the meeting or adjourned meeting or (in the case of a poll taken otherwise that at or on the same day as the meeting or adjourned meeting) the time appointed for the taking of the poll at which the vote is cast.

74.

Any corporation which is a member of the Company may by resolution of its directors or other governing body authorise such person as it thinks fit to act as its representative at any meeting of the Company or of any class of members of the Company. The person so authorised shall be entitled to exercise the same powers on behalf of such corporation as the corporation could exercise if it were an individual member of the Company and such corporation shall for the purposes of these presents be deemed to be present in person at any such meeting if a person so authorised is present thereat”.

(b)	Rights in respect of Dividends

“119.

The Company may by Ordinary Resolution declare dividends but no such dividend shall exceed the amount recommended by the Directors.

120.

If and so far as in the opinion of the Directors the profits of the Company justify such payments, the Directors may declare and pay the fixed dividends on any class of shares carrying a fixed dividend expressed to be payable on fixed dates on the half-yearly or other dates prescribed for the payment thereof and may also from time to time declare and pay interim dividends on shares of any class of such amounts and on such dates and in respect of such periods as they think fit.

121.

Unless and to the extend that the rights attached to any shares or the terms of issue thereof otherwise provide, all dividends shall (as regards any shares not fully paid throughout the period in respect of which the dividend is paid) be apportioned and paid pro rata according to the amounts paid on the shares during any portion or portions of the period in respect of which the dividend is paid. For the purposes of this Article no amount paid on a share in advance of calls shall be treated as paid on the share.

122.

No dividend shall be paid otherwise than out of profits available for distribution under the provisions of the Statutes.

123.

No dividend or other moneys payable on or in respect of a share shall bear interest as against the Company.

124.

(A)

The Directors may retain any dividend or other moneys payable on or in respect of a share on which the Company has a lien and may apply the same in or towards satisfaction of the debts, liabilities or engagements in respect of which the lien exists.

(B)

The Directors may retain the dividends payable upon shares in respect of which any person is under the provisions as to the transmission of shares hereinbefore contained entitled to become a member, or which any person is under those provisions entitled to transfer, until such person shall become a member in respect of such shares or shall transfer the same.

125.

The waiver in whole or in part of any dividend on any share by any document (whether or not under seal) shall be effective only if such document is signed by the shareholder (of the person entitled to the share in consequence of the death or bankruptcy of the holder) and delivered to the Company and if or to the extent that the same is accepted as such or acted upon by the Company.

126.

The Company may upon the recommendation of the Directors by Ordinary Resolution direct payment of a dividend in whole or in part by the distribution of specific assets (and in particular of paid-up shares or debentures of any other company) and the Directors shall give effect to such resolution. Where any difficulty arises in regard to such distribution, the Directors may settle the same as they think expedient and in particular may issue fractional certificates, may fix the value for distribution of such specific assets or any part thereof, may determine that cash payments shall be made to any members upon the footing of the value so fixed in order to adjust the rights of all parties and may vest any such specific assets in trustees as may seem expedient to the Directors.

127.

Any dividend or other moneys payable in cash on or in respect of a share may be paid by cheque or warrant sent through the post to the registered address of a member or person entitled thereto (or, if two or more persons are registered as joint holders of the share or are entitled thereto in consequence of the death or bankruptcy of the holder, to any one of such persons) or to such person at such address as such member or person or persons may by writing direct. Every such cheque or warrant shall be made payable to the order of the person to whom it is sent or to such person as the holder or joint holders or person or persons entitled to the share in consequence of the death or bankruptcy of the holder may direct and payment of the cheque or warrant by the banker upon whom it is drawn shall be a good discharge to the Company. Every such cheque or warrant shall be sent at the risk of the person entitled to the money represented thereby.

128.

If two or more persons are registered as joint holders of any share, or are entitled jointly to a share in consequence of the death or bankruptcy of the holder, any one of them may give effectual receipts for any dividend or other moneys payable or property distributable on or in respect of the share.

129.

Any resolution declaring a dividend on shares of any class, whether a resolution of the Company in General Meeting or a resolution of the Directors, may specify that the same shall be payable to the persons registered as the holders of such shares at the close of business on a particular date and thereupon the dividend shall be payable to them in accordance with their respective holdings so registered, but without prejudice to the rights inter se in respect of such dividend of transferors and transferees of any such shares.

130.

The payment by the Directors of any unclaimed dividends or other moneys payable on or in respect of a share into a separate account shall not constitute the Company a trustee in respect thereof. All dividends unclaimed after being declared may be invested or otherwise made use of by the Directors for the benefit of the Company and any dividend unclaimed after a period of six years from the date of declaration of such dividend may be forfeited and if so shall revert to the Company but the Directors may at any time thereafter at their absolute discretion annul any such forfeiture and pay the dividend so forfeited to the person entitled thereto prior to the forfeiture.

131.

A transfer of shares shall not pass the right to any dividend declared on such shares before the registration of the transfer”.

(c)	Rights in respect of Capital

“4.

Save as provided in Section 161 of the Act, no shares may be issued by the Directors without the prior approval of the Company in General Meeting but subject thereto and to the

provisions of these presents, and to any special rights attached to any shares for the time being issued, the Directors may allot or grant options over or otherwise dispose of the same to such persons on such terms and conditions and for such consideration and at such time and subject or not to the payment of any part of the amount thereof in cash as the Directors may think fit, and any shares may be issued with such preferential, deferred, qualified or special rights, privileges or conditions as the Directors may think fit, and preference shares may be issued which are or at the option of the Company are liable to be redeemed, the terms and manner of redemption being determined by the Directors.

(A)

Whenever the share capital of the Company is divided into different classes of shares, the special rights attached to any class may, subject to the provisions of the Statutes, be varied or abrogated either with the consent in writing of the holders of three-quarters in nominal value of the issued shares of the class or with the sanction of a Special Resolution passed at a separate General Meeting of the holders of the shares of the class (but not otherwise) and may be so varied or abrogated either whilst the Company is a going concern or during or in contemplation of a winding-up. To every such separate General Meeting all the provisions of these presents relating to the General Meetings of the Company and to the proceedings thereat shall mutatis mutandis apply, except that the necessary quorum shall be two persons at least holding or representing by proxy at least one-third in nominal value of the issued shares of the class and that any holder of shares of the class present in person or by proxy may demand a poll and that every such holder shall on a poll have one vote for every share of the class held by him, Provided always that where necessary majority for such a Special Resolution is not obtained at such General Meeting, consent in writing if obtained from the holders of three-quarters in nominal value of the issued shares of the class concerned within two months of such General Meeting shall be as valid and effectual as a Special Resolution carried at such General Meeting. The foregoing provisions of this Article shall apply to the variation or abrogation of the special rights attached to some only of the shares of any class as if each group of shares of the class differently treated formed a separate class the special rights whereof are to be varied.

(B)

The special rights attached to any class of shares having preferential rights shall not unless otherwise expressly provided by the terms of issue thereof be deemed to be varied by the creation or issue of further shares ranking as regards participation in the profits or assets of the Company in some or all respects pari passu therewith but in no respect in priority thereto.

The Company may from time to time by Ordinary Resolution, whether all the shares from the time being authorised shall have been issued or all the shares for the time being issued shall have been fully paid-up or not, increase its capital by such sum to be divided into shares of such amounts as the resolution shall prescribe.

Except so far as otherwise provided by the conditions of issue or by these presents, all new shares shall be subject to the provisions of the Statutes and of these presents with reference to allotment, payment of calls, lien, transfer, transmission, forfeiture and otherwise.

The Company may by Ordinary Resolution:-

(a) consolidate and divide all or any of its share capital into shares of larger amounts than its existing shares;

(b) cancel any shares which, at the date of the passing of the resolution, have not been taken, or agreed to be taken, by any person and diminish the amount of its capital by the amount of the shares so cancelled;

(c) sub-divide its shares, or any of them, into shares of smaller amount than is fixed by the Memorandum of Association (subject, nevertheless, to the provisions of the Statutes), and so that the resolution whereby any share is sub-divided may determine that, as between the holders of the shares resulting from such sub-division, one or more of the shares may, as compared with the others, have any such preferred, deferred or other special rights, or be subject to any such restrictions, as the Company has power to attach to unissued or new shares; and/or

(d) subject to the provisions of the Statutes, convert any class of shares into any other class of shares.

The Company may reduce its share capital or any capital redemption reserve fund, share premium account or other undistributable reserve in any manner and with and subject to any incident authorised and consent required by law.

20.

The Directors may from time to time make calls upon the members in respect of any moneys unpaid on their shares (whether on account of the nominal value of the shares or, when permitted, by way of a premium) but subject always to the terms of issue of such shares. A call shall be deemed to have been made at the time when the resolution of the Directors authorising the call was passed and may be made payable by installments.

21.

Each member shall (subject to receiving at least 14 days’ notice specifying the time or times and place of payment) pay to the Company at the time or times and place so specified the amount called on his shares. The joint holders of a share shall be jointly and severally liable to pay all calls in respect thereof. A call may be revoked or postponed as the Directors may determine.

22.

If a sum called in respect of a share is not paid before or on the day appointed for payment thereof, the person from whom the sum is due shall pay interest on the sum from the day appointed for payment thereof to the time of actual payment at such rate (not exceeding ten per cent. per annum) as the Directors determine but the Directors shall be at liberty in any case or cases to waive payment of such interest wholly or in part.

23.

Any sum (whether on account of the nominal value of the share or by way of premium) which by the terms of issue of a share becomes payable upon allotment or at any fixed date shall for all the purposes of these presents be deemed to be a call duly made and payable on the date on which by the terms of issue the same becomes payable. In case of non-payment all the relevant provisions of these presents as to payment of interest and expenses, forfeiture or otherwise shall apply as if such sum had become payable by virtue of a call duly made and notified.

24.

The Directors may on the issue of shares differentiate between the holders as to the amount of calls to be paid and the time of payment.

25.

The Directors may, if they think fit, receive from any member willing to advance the same all or any part of the moneys (whether on account of the nominal value of the shares or by way of

premium) uncalled and unpaid upon the shares held by him and such payment in advance of calls shall extinguish pro tanto the liability upon the shares in respect of which it is made and upon the money so received (until and to the extent that the same would but for such advance become payable) the Company may pay interest at such rate (not exceeding eight per cent. per annum) as the member paying such sum and the Directors may agree.

26.

If a member fails to pay in full any call or instalment of a call on the due date for payment thereof, the Directors may at any time thereafter serve a notice on him requiring payment of so much of the call or instalment as is unpaid together with any interest which may be accrued thereon and any expenses incurred by the Company by reason of such non-payment.

27.

The notice shall name a further day (not being less than fourteen days from the date of service of notice) on or before which and the place where the payment required by the notice is to be made, and shall state that in the event of non-payment in accordance therewith the shares on which the call has been made will be liable to be forfeited.

28.

If the requirements of any such notice as aforesaid are not complied with, any share in respect of which such notice has been given may at any time thereafter, before payment of all calls and interest and expenses due in respect thereof has been made, be forfeited by a resolution of the Directors to that effect. Such forfeiture shall include all dividends declared in respect of the forfeited share and not actually paid before forfeiture. The Directors may accept a surrender of any share liable to be forfeited hereunder.

29.

A share so forfeited or surrendered shall become the property of the Company and may be sold, re-allotted or otherwise disposed of either to the person who was before such forfeiture or surrender the holder thereof or entitled thereto or to any other person upon such terms and in such manner as the Directors shall think fit and at any time before a sale, re-allotment or disposition the forfeiture or surrender may be cancelled on such terms as the Directors think fit. The Directors may, if necessary, authorize some person to transfer or effect the transfer of a forfeited or surrendered share to any such other person as aforesaid.

30.

A member whose shares have been forfeited or surrendered shall cease to be a member in respect of the shares but shall notwithstanding the forfeiture or surrender remain liable to pay to the Company all moneys which at the date of forfeiture or surrender were presently payable by him to the Company in respect of the shares with interest thereon at ten per cent. per annum (or such lower rate as the Directors may determine) from the date of forfeiture or surrender until payment and the Directors may at their absolute discretion enforce payment without any allowance for the value of the shares at that time of forfeiture or surrender or waive payment in whole or in part.

31.

The Company shall have a first and paramount lien and charge on every share (not being a fully paid share) and on all dividends declared or payable in respect thereof for all moneys (whether presently payable or not) called or payable at a fixed time in respect of such share and for all moneys as the Company may be called upon by law to pay in respect of the shares of the member or deceased member. The Directors may waive any lien which has arisen and may resolve any share shall for some limited period be exempt wholly or partially from the provisions of this Article.

32.

The Company may sell in such manner as the Directors think fit any share on which the Company has a lien, but no sale shall be made unless some sum in respect of which the lien

exists is presently payable nor until the expiration of fourteen days after the notice in writing stating and demanding payment of the sum presently payable and giving notice of intention to sell in default shall have been given to the holder for the time being of the share or the person entitled thereto by reason of his death or bankruptcy. For the purpose of giving effect to any such sale the Directors may authorise some person to transfer or effect the transfer of the shares sold to the purchaser.

33.

The net proceeds of such sale after payment of the costs of such sale shall be applied in or towards payment or satisfaction of the debts or liabilities and any residue shall (subject to a like lien for sums not presently payable as existed upon the shares before the sale) be paid to the person entitled to the shares at the time of the sale or to his executors, administrators or assigns, as he may direct.

34.

A statutory declaration in writing that the declarant is a Director or the Secretary of the Company and that a share has been duly forfeited or surrendered or sold to satisfy a lien of the Company on a date stated in the declaration shall be conclusive evidence of the facts therein stated as against all persons claiming to be entitled to the share. Such declaration and the receipt of the Company for the consideration (if any) given for the share of the sale, re-allotment or disposal thereof together (where the same be required) with the share certificate delivered to a purchaser or allottee thereof shall (subject to the execution of a transfer if the same be required) constitute a good title to the share and the share shall be registered in the name of the person to whom the share is sold, re-allotted or disposed of. Such person shall not be bound to see to the application of the purchase money (if any) nor shall his title to the share be affected by any irregularity or invalidity in the proceedings relating to the forfeiture, surrender, sale, re-allotment or disposal of the share.

118.

The Directors may from time to time set aside out of the profits of the Company and carry to reserve such sums as they think proper which, at the discretion of the Directors, shall be applicable for any propose to which the profits may properly be applied and pending such application may either be employed in the business of the Company or be invested. The Directors may divide the reserve into such special funds as they think fit and may consolidate into one fund any special funds or any parts of the special funds into which the reserve may be divided. The Directors may also, without placing the same to reserve, carry forward any profits. In carrying sums to reserve and in applying the same the Directors shall comply with the provisions of the Statutes.

132.

The Directors may, with the sanction of an Ordinary Resolution of the Company, capitalise any sum standing to the credit of an of the Company’s reserve accounts (including Share Premium Account, Capital Redemption Reserve Fund or other undistributable reserve) or any sum standing to the credit of profit and loss account by appropriating such sum to the holders of shares in the Register of Members at the close of business on the date of the Resolution (or such other date as may be specified therein or determined as therein provided) in proportion to their then holdings of shares and applying such sum on their behalf in paying up in full unissued shares (or, subject to any special rights previously conferred on any shares or class of shares for the time being issued, unissued shares of any other class not being redeemable shares) for allotment and distribution credited as fully paid up to and amongst them as bonus shares in the proportion aforesaid. The Directors may do all acts and things considered necessary or expedient to give effect to any such capitalisation, with full power to the Directors to make such provisions as they think fit for any fractional entitlements which would arise on the basis aforesaid (including provisions whereby fractional entitlements are

disregarded or the benefit thereof accrues to the Company rather than to the members concerned). The Directors may authorise any person to enter on behalf of all the members interested in an agreement with the Company providing for any such capitalisation and matters incidental thereto and any agreement made under such authority shall be effective and binding on all concerned.

146.

The Directors shall have power in the name and on behalf of the Company to present a petition to the court for the Company to be wound up.

147.

If the Company shall be wound up (whether the liquidation is voluntary, under supervision, or by the court) the Liquidator may, with the authority of a Special Resolution, divide among the members in specie or kind the whole or any part of the assets of the Company and whether or not the assets shall consist of property of one kind or shall consist of properties of different kinds, and may for such purpose set such value as he deems fair upon any one or more class or classes of property and may determine how such division shall be carried out as between the members of different classes of members. The Liquidator may, with the like authority, vest any part of the assets in trustees upon such trusts for the benefit of members as the Liquidator with the like authority shall think fit, and the liquidation of the Company may be closed and the Company dissolved, but so that no contributory shall be compelled to accept any shares or other property in respect of which there is a liability”.

Parties to the Scheme		· ASE Test Limited, referred to herein as ASE Test, is a company incorporated and existing under the laws of the Republic of Singapore, having its principal executive offices at 10 West Fifth Street, Nantze Export Processing Zone, Kaohsiung, Taiwan, Republic of China. ASE Test is one of the world’s largest independent providers of semiconductor testing services, including front-end engineering testing, wafer probing, final production testing of packaged semiconductors and other test-related services. · Advanced Semiconductor Engineering, Inc., referred to herein as ASE Inc., is a company incorporated and existing under the laws of Taiwan, Republic of China, having its principal executive offices at Room 1901, TWTC International Trade Building, 19/F, 333, Keelung Road., Sec. 1, Taipei 110, Taiwan, Republic of China. ASE Inc. is one of the world’s largest independent providers of integrated circuit packaging services and, together with its subsidiary ASE Test, the world’s largest independent provider of semiconductor testing services, including front-end engineering testing, wafer probing and final testing services. As of November 30, 2007, ASE Inc. indirectly owns approximately 50.3% of the outstanding ASE Test ordinary shares. See “Parties to the Scheme” on page [ · ].

The Scheme; the Scheme Implementation Agreement		· Pursuant to the scheme implementation agreement, dated as of September 4, 2007, between ASE Inc. and ASE Test, ASE Inc. agreed to acquire the outstanding ASE Test ordinary shares held by ASE Test shareholders (other than ASE Inc. and its subsidiaries), by way of a scheme of arrangement under Section 210 of the Companies Act, Chapter 50 of Singapore, referred to herein as the scheme, which constitutes a “going private” transaction subject to the requirements of Rule 13e-3 under the U.S. Securities Exchange Act of 1934, as amended, referred to herein as the Exchange Act. Upon the effectiveness of the scheme, ASE Test will become an indirect wholly-owned subsidiary of ASE Inc. and cease to be a publicly traded company. See “The Scheme Implementation Agreement” beginning on page [ · ]. A copy of the scheme implementation agreement is attached as Appendix A to this scheme document. You should read the scheme implementation agreement in its entirety because it, and not this scheme document, is the legal document that governs the scheme.

Scheme Consideration		Upon the effectiveness of the scheme, ASE Test shareholders (other than ASE Inc. and its subsidiaries) of record as of the books closure date (as described on page [ · ] of the scheme document) will be entitled to receive the following, referred to herein as the scheme consideration: · for each ASE Test ordinary share listed on The NASDAQ Global Market, referred to herein as an ASE Test Nasdaq Share, US$14.78 in cash; and · for each Taiwan depositary share (representing 0.0125 ASE Test ordinary shares) listed on the Taiwan Stock Exchange, referred to herein as an ASE Test TDS, the NT$

		equivalent of US$0.185 in cash (based on the prevailing exchange rate calculated in the manner described under “The Scheme Implementation Agreement—Scheme Consideration” on page [ · ] of the scheme document).

		See “The Scheme Implementation Agreement—Scheme Consideration” beginning on page [ · ]. On October 31, 2007, ASE Inc. issued a statement announcing that it does not intend to revise the scheme consideration. Accordingly, pursuant to the provisions of Rule 20.2 of the Singapore Code on Take-overs and Mergers, referred to herein as the Singapore Code, ASE Inc. will not be permitted to increase the scheme consideration or amend the terms of its offer in connection with the scheme. Furthermore, in the event the scheme does not become effective due to the failure to obtain the requisite shareholder approval, pursuant to the provisions of Rule 33.1 of the Singapore Code, ASE Inc. will not be permitted to make a further or new offer for the shares of ASE Test for a period of 12 months from the date of the court meeting (as defined below), unless it obtains the prior consent of the Securities Industry Council of Singapore, referred to herein as the SIC.

Treatment of Options		Upon the effectiveness of the scheme, each option granted under the 1999, 2000 and 2004 ASE Test share option plans to subscribe for ASE Test ordinary shares, referred to herein as an ASE Test op tion , that remains outstanding as of the books closure date, whether or not vested as of the effective date of the scheme , will be treated as follows: · each ASE Test option that has a per share exercise price lower than the per share scheme consideration, referred to herein as an in-the-money ASE Test option, will be deemed to have been exercised as of the books closure date by ASE Test on behalf of the option holder on a cashless basis through a broker, and the ASE Test ordinary shares issued upon such mandatory exercise of the option will be acquired by ASE Inc. for the scheme consideration of US$14.78 per ASE Test Nasdaq Share in cash, and as a result the option holder will receive a cash payment equal to the excess of the per share scheme consideration over the per share exercise price of such ASE Test option, less any interest, fees and charges of the broker; and · each ASE Test option that has a per share exercise price equal to or higher than the per share scheme consideration, referred to herein as an out-of-the-money ASE Test option, will be cancelled without any payment to the option holder. See “The Scheme Implementation Agreement—Treatment of Options” on page [ · ].

Court Meeting; Persons Entitled to Vote; Vote Required; and Quorum		· The High Court of the Republic of Singapore, referred to herein as the court, has directed that a meeting of ASE Test shareholders be convened for the purpose of approving and adopting the scheme, referred to herein as the court meeting. The court meeting will be held on [ · ] at [ · ][a.m./p.m.], Singapore time, at [ · ]. · At the court meeting, all ASE Test shareholders (other than ASE Inc. and its subsidiaries, to which the scheme is not applicable) of record as of [ · ] are entitled to vote on the proposal to approve and adopt the scheme. However, pursuant to the Singapore Code, ASE Test shareholders who are persons acting in concert with ASE Inc. in relation to the scheme, referred to herein as concert parties of ASE Inc., are required to abstain from voting on the proposal to approve and adopt the scheme at the court meeting. Furthermore, pursuant to the terms of the scheme implementation agreement and undertakings delivered to ASE Inc. and ASE Test, ASE Test shareholders who are affiliates of ASE Inc. will also abstain from voting on the proposal to approve and adopt the scheme at the court meeting. · The affirmative vote of a majority in number of the unaffiliated ASE Test shareholders

		present and voting, in person or by proxy, at the court meeting, representing not less than 75% in value of the ASE Test ordinary shares held by the unaffiliated ASE Test shareholders present and voting, in person or by proxy, at the court meeting, is required to approve and adopt the scheme. The unaffiliated ASE Test shareholders are ASE Test shareholders other than ASE Inc. and its affiliates.

		· The presence, in person or by proxy, at the court meeting of unaffiliated ASE Test shareholders holding one-third of the ASE Test ordinary shares held by all unaffiliated ASE Test shareholders of record as of [ · ] will constitute a quorum, which is necessary to hold the court meeting. See “—Regulatory Matters” below; “The Court Meeting” beginning on page [ · ]; and “Special Factors Regarding the Scheme—Regulatory Matters” on page [ · ].

Voting by Proxy		Before voting your ASE Test Nasdaq Shares or ASE Test TDSs, we encourage you to read this scheme document in its entirety, including its appendices and materials incorporated by reference, and carefully consider how the scheme will affect you. If you are a record holder of ASE Test ordinary shares, we encourage you to submit a proxy so that your vote will be counted even if you later decide not to attend the court meeting. Please complete, sign, date and return the enclosed proxy form as soon as possible, and no later than [ · ]. If you hold ASE Test Nasdaq Shares through a broker, you may submit your voting instructions by mail, by telephone or by the Internet in accordance with the procedures provided by your broker. If you hold ASE Test TDSs, you should follow the procedures provided by the depositary of ASE Test TDSs to submit your voting instructions. See “The Court Meeting” beginning on page [ · ].

Recommendation of ASE Test’s Board of Directors		· Following the receipt of a proposal from ASE Inc. in respect of the scheme, the board of directors of ASE Test established a special committee comprised of two directors of ASE Test who are independent for purposes of the scheme to, among other things, review, evaluate, negotiate and consider all matters which may arise in connection with the scheme. The special committee was comprised of Mr. Albert C.S. Yu and Mr. Guan Seng Sim. The special committee determined that the scheme consideration is fair to the unaffiliated ASE Test shareholders and recommended that the board of directors of ASE Test: (i) approve the scheme implementation agreement; and (ii) recommend the approval and adoption of the scheme by the unaffiliated ASE Test shareholders. · At a duly held meeting on September 4, 2007, the board of directors of ASE Test, with only those directors who are independent for purposes of the scheme voting: (i) unanimously determined that the scheme implementation agreement, the scheme and the other transactions contemplated thereby are fair to and in the best interests of ASE Test shareholders (other than ASE Inc. and its subsidiaries); (ii) unanimously approved the scheme implementation agreement and the transactions contemplated thereby; and (iii) unanimously resolved to recommend the approval and adoption of the scheme by the unaffiliated ASE Test shareholders. The directors of ASE Test who are independent for purposes of the scheme, namely Mr. Albert C.S. Yu, Mr. Guan Seng Sim and Mr. David D.H. Tsang, are referred to in this scheme document as the independent directors. Due to their affiliation with ASE Inc., the interested directors of ASE Test, namely Mr. Jason C.S. Chang, Mr. Richard H.P. Chang, Mr. Joseph Tung, Mr. Jeffrey Chen, Mr. Alan T.C. Cheng, Mr. Raymond Lo, Mr. Freddie Liu and Mr. Ko-Chien Chin, abstained from the deliberations on the scheme, including without limitation, the scheme consideration, and from voting on the foregoing resolutions.

Opinion of the Special Committee’s Financial Advisor		· The special committee engaged Lehman Brothers Inc., referred to herein as Lehman Brothers, as its financial advisor in connection with its evaluation of the scheme. On September 4, 2007, Lehman Brothers delivered its oral and written opinion to the special committee that, as of that date and based upon and subject to the factors and assumptions set forth in its written opinion, the consideration to be received by the unaffiliated ASE Test shareholders in the scheme was fair, from a financial point of view, to such shareholders. The full text of Lehman Brothers’ written opinion is attached to this scheme document as Appendix B. We encourage you to read this opinion carefully in its entirety for a description of the procedures followed, assumptions made, matters considered and limitations on the review undertaken. Lehman Brothers’ opinion was provided to the special committee in connection with its evaluation of the scheme and does not constitute a recommendation to any shareholder of ASE Test as to how such shareholder should vote with respect to the scheme or any other matter. For a more complete description of the opinion and the review undertaken in connection with such opinion, together with the fees payable to Lehman Brothers by ASE Test, see “Special Factors Regarding the Scheme—Opinion of Lehman Brothers” beginning on page [ · ] and Appendix B.

Opinion of the Independent Financial Advisor; Recommendation of ASE Test’s Independent Directors		· Pursuant to the Singapore Code, ASE Test is required to engage an independent financial advisor to advise the independent directors on the scheme, and the independent directors are required to make a recommendation to the ASE Test shareholders (other than ASE Inc. and its subsidiaries) in relation to the scheme after having considered the advice of the independent financial advisor. Under the Singapore Code, the primary role of the independent financial advisor is to render an opinion on the scheme consideration to the independent directors after the scheme consideration has been agreed upon between the parties. On November 15, 2007, the independent directors engaged ANZ Singapore Limited, referred to herein as ANZ Singapore or the IFA, as their independent financial advisor. On [ · ], ANZ Singapore rendered its written opinion to the independent directors that, based upon and having considered the information that has been made available to it and the factors set out in its opinion, as of the date of its opinion, the scheme consideration is fair, from a financial point of view, to ASE Test shareholders (other than ASE Inc. and its subsidiaries). The full text of ANZ Singapore’s opinion is attached to this scheme document as Appendix K. We encourage you to read this opinion carefully in its entirety for a description of the assumptions made, matters considered and limitations on the review undertaken by ANZ Singapore in forming its opinion. ANZ Singapore’s opinion is not intended to be and does not constitute a recommendation to any ASE Test shareholder as to how such shareholder should vote in connection with the scheme. For a more complete description of the opinion and the review undertaken in connection with such opinion, together with the fees payable to ANZ Singapore by ASE Test, see “Special Factors Regarding the Scheme—Opinion of ANZ Singapore” beginning on page [ · ] and Appendix K. Having considered the terms of the scheme, the recommendations of the special committee and the board of directors of ASE Test (with only the independent directors voting and the interested directors abstaining from voting), the opinion of Lehman Brothers and the opinion of ANZ Singapore, the independent directors recommend that you vote FOR the approval and adoption of the scheme. See “Special Factors Regarding the Scheme—Recommendation of ASE Test’s Independent Directors” beginning on page [ · ].

Applicability of Rules Related to “Going Private” Transactions; Positions as to the Fairness of and Reasons for the Scheme		· The requirements of Rule 13e-3 under the Exchange Act, referred to herein as Rule 13e-3, apply to the scheme because ASE Inc. and ASE Test are engaging in a “going private” transaction under the Exchange Act. To comply with the requirements of Rule 13e-3, ASE Inc. and ASE Test are required to make certain statements as to, among other matters, their purposes and reasons for the scheme, and their beliefs as to the fairness of the scheme to the unaffiliated ASE Test shareholders. See “Special Factors Regarding the Scheme—ASE Test’s Reasons for the Scheme; Recommendation of ASE Test’s Board of Directors” and “—ASE Inc.’s Reasons for Effecting the Scheme; Position as to Fairness” beginning on pages [ · ] and [ · ], respectively.

Accounting Treatment of the Scheme		The scheme is expected to be accounted for using the purchase method of accounting for financial accounting purposes. See “Special Factors Regarding the Scheme—Accounting Treatment of the Scheme” beginning on page [ · ].

Appraisal Rights		Once the scheme is approved and adopted by the requisite majority of the unaffiliated ASE Test shareholders, is sanctioned by the court and becomes effective, it will be binding on all ASE Test shareholders. Dissenting ASE Test shareholders may file an objection with the court against the granting of the court sanction, but no appraisal rights are available to dissenting ASE Test shareholders in connection with a scheme of arrangement effected under Singapore law.

Conditions to the Scheme		In addition to the approval and adoption of the scheme by the unaffiliated ASE Test shareholders, the scheme is subject to the satisfaction or waiver of a number of conditions, including the following: · the making of required filings with each of the Investment Commission of the Republic of China, referred to herein as the ROC IC, and the Fair Trade Commission of the Republic of China, referred to herein as the ROC FTC; · the receipt of applicable regulatory approvals and such approvals not being revoked on or before the effective date of the scheme; · the receipt of authorizations, consents, clearances, permissions and approvals necessary or required for the implementation of the scheme, except as would not be reasonably expected to have a material adverse effect on ASE Test or on the performance in all material respects by ASE Inc. of its obligations under the scheme implementation agreement; · the accuracy of each party’s representations and warranties contained in the scheme implementation agreement (disregarding any material or materiality qualifications therein) in all material respects at and as of the effective date of the scheme as if made at and as of such time, and the performance by each party in all material respects of all of its obligations under the scheme implementation agreement required to be performed by it on or prior to the effective date of the scheme; · the sanction of the scheme by the court, and the lodgment of the court order with the Accounting and Corporate Regulatory Authority of Singapore, referred to herein as the ACRA; · all independent directors having joined in the recommendation of the approval and adoption of the scheme by the unaffiliated ASE Test shareholders; · the receipt of all approvals for the implementation of the treatment of outstanding ASE Test options; and · the absence of any injunction or other court order or legal restraint or prohibition

		preventing the scheme from becoming effective. See “The Scheme Implementation Agreement—Conditions to the Scheme” beginning on page [ · ]. As described below under “—Regulatory Matters”, as a condition to the ruling that certain provisions of the Singapore Code do not apply to the scheme, ASE Inc. is required to consult with the SIC, prior to invoking any of the conditions to the scheme.

Termination of the Scheme Implementation Agreement		The scheme implementation agreement may be terminated under certain circumstances, including the following: · by either party upon the issuance of a final and non-appealable court order permanently prohibiting the scheme; · if there has been a material breach by any party of its obligations under the scheme implementation agreement, by the party not in default after prior consultation with the SIC and any other applicable government authority, upon 14 days’ advance written notice to the breaching party; · by either party if the unaffiliated ASE Test shareholders have failed to approve and adopt the scheme at the court meeting or if the court does not sanction the scheme and such court decision is final and non-appealable; · by either party if all of the conditions to the scheme are not satisfied (or waived) on or prior to June 4, 2008 or such other date as the parties may agree in writing (subject to any required consent of the SIC or any other regulatory or governmental authority), provided that a party whose breach of the scheme implementation agreement has resulted in the conditions to the scheme not being satisfied on or prior to the date described above may not terminate the scheme implementation agreement pursuant to this provision; · by ASE Inc. if ASE Test or its directors have, directly or indirectly, withdrawn or modified in any manner adverse to ASE Inc. the ASE Test’s board of directors’ recommendation of approval and adoption of the scheme by the unaffiliated ASE Test shareholders, or approved or recommended an alternative acquisition proposal, or otherwise failed to comply with the non-solicitation provisions of the scheme implementation agreement, or if ASE Test takes any action or makes any public statement, or authorizes or permits any of its independent directors to take any action or make any public statement, inconsistent with ASE Test’s board of directors’ recommendation in favor of the scheme; · by ASE Test if, in accordance with and pursuant to the “fiduciary-out” exception described below in “The Scheme Implementation Agreement—Non-Solicitation; Fiduciary-Out”, ASE Test or its directors have withdrawn or modified in any manner adverse to ASE Inc. the ASE Test’s board of directors’ recommendation of approval and adoption of the scheme by the unaffiliated ASE Test shareholders, or approved or recommended an alternative acquisition proposal; or · upon the mutual written consent of the parties. See “The Scheme Implementation Agreement—Termination Rights” beginning on page [ · ].

Regulatory Matters		• Taiwan . ASE Inc.’s proposed acquisition of ASE Test ordinary shares by way of the scheme is subject to the prior approvals of the ROC IC and the ROC FTC, each of which has been obtained by ASE Inc.

Financing Arrangements		The scheme is not subject to any financing conditions.

On September 4, 2007, ASE Inc. entered into a commitment letter with Citibank, N.A., Taipei Branch, referred to herein as Citibank Taiwan, pursuant to which Citibank Taiwan committed to provide a term credit facility to ASE Inc., and Citigroup Global Markets Asia Limited agreed to act as the arranger of the term credit facility. In compliance with the Singapore Code, Citigroup Global Markets Taiwan Ltd., referred to herein as Citigroup Taiwan, as financial advisor to ASE Inc., has confirmed that sufficient financial resources are available to ASE Inc. to satisfy the aggregate scheme consideration and amounts payable by ASE Inc. in respect of the treatment of outstanding ASE Test options in connection with the scheme.

Q:	What is the scheme?

A:	On September 4, 2007, ASE Inc. and ASE Test entered into a scheme implementation agreement pursuant to which ASE Inc. would acquire the outstanding ASE Test ordinary shares held by ASE Test shareholders (other than ASE Inc. and its subsidiaries) by way of a scheme of arrangement under Singapore law.

	The scheme is a court-supervised process under Section 210 of the Companies Act, Chapter 50 of Singapore, in which a company proposes a transaction to its shareholders which, if approved and adopted by the requisite statutory majority of shareholders, is binding on all shareholders once sanctioned by the court and becomes effective.

Q:	Who is entitled to the scheme consideration, and what will ASE Test shareholders receive in the scheme? What is the effect of the scheme?

A:	Upon the effectiveness of the scheme, ASE Test shareholders (other than ASE Inc. and its subsidiaries) of record as of the books closure date (as described on page [ · ] of this scheme document) are entitled to receive the following scheme consideration (net of applicable withholding tax, if any, and subject to reduction to the extent any dividend or other distribution is made or paid on or prior to the effectiveness of the scheme):

	(i)	for each ASE Test Nasdaq Share, US$14.78 in cash; and

	(ii)	for each ASE Test TDS, the NT$ equivalent of US$0.185 in cash (based on the prevailing exchange rate calculated in the manner described on page [ · ] of this scheme document).

	Upon the effectiveness of the scheme, ASE Test will become an indirect wholly-owned subsidiary of ASE Inc., and you will no longer have any interest in ASE Test ’ s future earnings or growth. The ASE Test Nasdaq Shares and ASE Test TDSs will thereafter be delisted from The NASDAQ Global Market and the Taiwan Stock Exchange, respectively, and the r egistration of the ASE Test ordinary shares and ASE Test ’ s reporting obligations under the Exchange Act will be terminated upon application to the United States Securities and Exchange Commission, referred to herein as the SEC.

	The scheme will become effective when a copy of the order of the court sanctioning the scheme under Section 210 of the Companies Act, Chapter 50 of Singapore is duly lodged with the ACRA.

Q:	What is the legal effect of the statement by ASE Inc. that it does not intend to revise the scheme consideration?

A:	ASE Inc. issued a statement on October 31, 2007, announcing that it does not intend to revise the scheme consideration. Accordingly, pursuant to the provisions of Rule 20.2 of the Singapore Code, ASE Inc. will not be permitted to increase the scheme consideration or amend the terms of its offer in connection with the scheme. Furthermore, in the event the scheme does not become effective due to the failure to obtain the requisite shareholder approval, pursuant to the provisions of Rule 33.1 of the Singapore Code, ASE Inc. will not be permitted to make a further or new offer for the shares of ASE Test for a period of 12 months from the date of the court meeting, unless it obtains the prior consent of the SIC.


Q:	What is the court meeting? Who will be entitled to vote?

A:	The court meeting was directed to be convened by the court for the purpose of approving and adopting the scheme and will be held on [ · ] at [ · ][a.m./p.m.], Singapore time, at [ · ]. At the court meeting, all ASE Test

	shareholders (other than ASE Inc. and its subsidiaries) of record as of [ · ] will be entitled to vote on the proposal to approve and adopt the scheme, except that those ASE Test shareholders who are concert parties of ASE Inc. or affiliates of ASE Inc. will abstain from voting. See “The Court Meeting” beginning on page [ · ] and “Special Factors Regarding the Scheme—Regulatory Matters” on page [ · ].

Q:	What quorum and shareholder vote are required to approve and adopt the scheme?

A:	A quorum is required for the transaction of business at the court meeting. The presence at the court meeting, in person or by proxy, of unaffiliated ASE Test shareholders holding one-third of the outstanding ASE Test ordinary shares held by all unaffiliated ASE Test shareholders of record as of [ · ] will constitute a quorum.

	The affirmative vote of a majority in number of the unaffiliated ASE Test shareholders present and voting, either in person or by proxy, at the court meeting, representing not less than 75% in value of the ASE Test ordinary shares held by the unaffiliated ASE Test shareholders present and voting, either in person or by proxy, at the court meeting, is required to approve and adopt the scheme.

Q:	How do ASE Test’s board of directors and the independent directors recommend that I vote? Why are there two sets of recommendations?

A:	Upon the recommendation of the special committee, the board of directors of ASE Test, with only the independent directors voting and the interested directors abstaining from voting, unanimously determined that the scheme implementation agreement, the scheme and the other transactions contemplated thereby are fair to and in the best interests of ASE Test shareholders (other than ASE Inc. and its subsidiaries), approved the scheme implementation agreement and the transactions contemplated thereby, and resolved to recommend the approval and adoption of the scheme by the unaffiliated ASE Test shareholders. Accordingly, the board of directors of ASE Test recommends that you vote FOR the approval and adoption of the scheme. For a discussion of the material factors considered by the special committee and the board of directors of ASE Test in reaching their conclusions and the reasons why the special committee and the board of directors of ASE Test determined that the scheme consideration is fair to the unaffiliated ASE Test shareholders, see “ Special Factors Regarding the Scheme — ASE Test ’ s Reasons for the Scheme; Recommendation of ASE Test ’ s Board of Directors” beginning on page [ · ].

	Pursuant to the Singapore Code, the independent directors are required to make a recommendation to the ASE Test shareholders (other than ASE Inc. and its subsidiaries) in relation to the scheme. Having considered the terms of the scheme, the recommendatio ns of the special committee and the board of directors of ASE Test (with only the independent directors voting and the interested directors abstaining from voting), the opinion of Lehman Brothers and the opinion of ANZ Singapore, the independent directors recommend that you vote FOR the approval and adoption of the scheme. For a discussion of the material factors considered by the independent directors of ASE Test in reaching their recommendation, see “ Special Factors Regarding the Scheme — Recommendation of ASE Test ’ s Independent Directors” beginning on page [ · ].

Q:	What is the special committee and who are its members?

A:	Following the receipt of a proposal from ASE Inc. in respect of the scheme, the board of directors of ASE Test established a special committee comprised of two independent directors to, among other things, review, evaluate, negotiate and consider all matters which may arise in connection with the scheme. The members of the special committee are Mr. Albert C.S. Yu and Mr. Guan Seng Sim.

Q:	Why is there a separate independent financial advisor advising the independent directors as to the scheme in addition to the financial advisor advising the special committee of ASE Test?

A:	Following the establishment of the special committee, the special committee engaged Lehman Brothers to act as its financial advisor with respect to its evaluation of the scheme. Lehman Brothers advised and assisted the special committee in the review, evaluation, negotiation and consideration of the scheme, provided the special committee with Lehman Brothers’ analysis of the financial terms of the proposed scheme, and, on September 4, 2007, rendered its oral and written opinion to the special committee as to the fairness from a financial point of view of the scheme consideration to be received by the unaffiliated ASE Test shareholders in the scheme.

	In compliance with the Singapore Code, following the execution of the scheme implementation agreement, the independent directors engaged ANZ Singapore as the independent financial advisor to advise them on the scheme. Under the Singapore Code, the primary role of the independent financial advisor is to render an opinion on the scheme consideration to the independent directors after the scheme consideration has been agreed upon between the parties. On [ · ], ANZ Singapore rendered its written opinion to the independent directors that, based upon and having considered the information that has been made available to it and the factors set out in its opinion, as of the date of its opinion, the scheme consideration is fair from a financial point of view to ASE Test shareholders (other than ASE Inc. and its subsidiaries).

Q:	What do I need to do now?

A:	You should carefully read and consider the information contained in this scheme document. We encourage you to vote by submitting your proxy whether or not you plan to attend the court meeting, so that your vote will be counted if you later decide not to attend the court meeting.

	If you are a record holder of ASE Test ordinary shares as of [ · ], please complete, sign, date and return the enclosed proxy form as soon as possible, and no later than [ · ]. Your signed proxy form must be received no later than [ · ] in order for your vote to be counted at the court meeting.

Q:	If my ASE Test Nasdaq Shares are held in “street name” by my broker, will my broker vote my shares for me?

A:	If you hold your ASE Test Nasdaq Shares in “street name”, you should follow the procedures provided by your broker regarding how to instruct your broker to vote your shares.

Q:	If I hold ASE Test TDSs representing ASE Test ordinary shares, how will my shares be voted?

A:	If you are a record holder of ASE Test TDSs or if you hold ASE Test TDSs in “street name” through a broker, you should follow the procedures provided by the depositary of ASE Test TDSs in order to submit your voting instructions.

Q:	How are votes counted?

A:	You may vote FOR or AGAINST the approval and adoption of the scheme, or you may abstain from voting on the scheme. Abstentions will not be counted as votes cast or shares voting on the proposal, but will count for the purpose of determining whether a quorum is present.

Q:	Can I revoke or change my vote?

A:	Yes, you can change your vote at any time before your proxy is voted at the court meeting. If you are a record holder of ASE Test ordinary shares, you may revoke your proxy by notifying the Secretary of ASE Test in writing or by delivering a new proxy, in each case, dated after the date of the proxy being revoked. In addition, you may revoke your proxy by attending the court meeting and voting in person. However, simply attending the court meeting will not revoke your proxy. If you have instructed a broker to vote your shares or hold your shares in the form of ASE Test TDSs, the above-described options for changing your vote do not apply; instead, you must follow the instructions received from your broker or the depositary of ASE Test TDSs, as applicable, to change your vote.

Q:	Who will count the votes at the court meeting?

A:	At the court meeting, a representative of [ · ] will count the votes and act as an inspector of voting.

Q:	What does it mean if I get more than one proxy card or voting instruction card?

Please complete and return all of the proxy cards and voting instruction cards you receive to ensure that all your ASE Test Nasdaq Shares or ASE Test TDSs are voted.

Q:	When is the scheme expected to become effective?

A:	If the scheme is approved and adopted by the requisite majority of the unaffiliated ASE Test shareholders at the court meeting and all other conditions to the scheme are satisfied, it is anticipated that the scheme will become effective during the first quarter of 2008. However, it is possible that factors outside of the control of either ASE Inc. or ASE Test could result in the scheme becoming effective at a later time or not becoming effective at all.

Q:	Should I send in my share certificates now?

A:	No. You will be notified of the procedures to surrender your share certificates and receive the scheme consideration after the scheme has become effective.

Q:	Is the scheme expected to be taxable to me?

A:	It is expected that the scheme will be a taxable disposition for most holders of ASE Test ordinary shares. U.S. holders (as defined on page [ · ]) should see “Special Factors Regarding the Scheme—United States Federal Income Tax Consequences” beginning on page [ · ]. Taiwan holders should see “Special Factors Regarding the Scheme—Republic of China Income Tax Consequences” beginning on page [ · ].

Q:	Am I entitled to appraisal rights?

A:	No. Once the scheme is approved and adopted by the unaffiliated ASE Test shareholders and sanctioned by the court and becomes effective, it will be binding on all ASE Test shareholders. Dissenting ASE Test shareholders may file an objection with the court against the granting of the court sanction, but no appraisal rights are available to dissenting shareholders in connection with a scheme of arrangement effected under Singapore law.

Q:	Who should I contact with additional questions?

A:	If you have more questions about the scheme, need assistance in submitting your proxy or voting your shares, or need additional copies of the scheme do cument or the enclosed proxy form, you should contact MacKenzie

1.	INTRODUCTION

	We, ANZ Singapore Limited, act as independent financial adviser to the independent directors of ASE Test Limited (“ ASE Test ”) in connection with the proposed privatisation by Advanced Semiconductor Engineering, Inc. (“ ASE Inc. ”) of ASE Test by way of a scheme of arrangement (the “ Scheme ”) under section 210 of the Companies Act, Chapter 50 of Singapore and in accordance with certain provisions of the Singapore Code on Take-overs and Mergers (the “ Code ”).

	We have prepared this letter for inclusion in the scheme document to be despatched to shareholders of ASE Test in connection with the Scheme (the “ Scheme Document ”).

2.	UNAUDITED CONSOLIDATED INTERIM RESULTS FOR THE NINE MONTHS ENDED 30 SEPTEMBER 2007

	Pursuant to the Code, we have examined the unaudited consolidated interim results of ASE Test and its subsidiaries for the nine months ended 30 September 2007 (the “ Unaudited Interim Results ”), a copy of which is set out in Appendix G to the Scheme Document, and have discussed the Unaudited Interim Results with certain senior management of ASE Test who are responsible for their preparation. We have also considered the review report dated December 11, 2007 from Deloitte & Touche, the auditors of ASE Test, addressed to the Board of Directors of ASE Test relating to the unaudited interim results of ASE Test and its subsidiaries for the three months and nine months ended 30 September 2006 and 2007. We have relied upon the accuracy and completeness in all material respects of all financial and other information discussed with us and have assumed their accuracy and completeness in all material respects for the purposes of rendering this letter. Save as provided in this letter, we do not express any other opinion on the Unaudited Interim Results.

3.	REPORT

	On the basis of the foregoing, we are of the view that the Unaudited Interim Results (for which the Directors of ASE Test are solely responsible) was prepared after due and careful enquiry.
