The obligations of the International Underwriters to purchase the International Underwritten Securities and the International Option Securities, as the case may be, shall be subject to the accuracy of the representations and warranties on the part of the Company and the Selling Shareholders contained in this Agreement as of the Execution Time, the Closing Date and any settlement date pursuant to Section 3 hereof, to the accuracy of the statements of the Company and the Selling Shareholders made in any certificates pursuant to the provisions hereof, to the performance by the Company and the Selling Shareholders of their respective obligations under this Agreement and to the following additional conditions: (i) If the Registration Statement and the ADR Registration Statement have not become effective prior to the Execution Time, unless the U.S. Representatives and the International Representatives agree in writing to a later time, the Registration Statement and the ADR Registration Statement will become effective not later than (a) 6:00 PM New York City time on the date of determination of the public offering price, if such determination occurred at or prior to 3:00 PM New York City time on such date or (b) 9:30 AM New York City time on the Business Day following the day on which the public offering price was determined, if such determination occurred after 3:00 PM New York City time on such date; if filing of either of the Prospectuses, or any supplement thereto, is required pursuant to Rule 424(b), the Prospectuses, and any such supplement, will be filed in the manner and within the time period required by Rule 424(b); and no stop order suspending the effectiveness of the Registration Statement or the ADR Registration Statement shall have been issued and no proceedings for that purpose shall have been instituted or threatened. (ii) On each of the Closing Date and any settlement date, the Company shall have requested and caused Simpson Thacher & Bartlett, United States counsel for the Company, to have furnished to the Representatives their opinion, dated the Closing Date or the settlement date, as the case may be, to the effect that: (a) The Underwriting Agreements have been duly executed and delivered by the Company in accordance with the laws of the State of New York. 24 (b) The Deposit Agreement has been duly executed and delivered by the Company in accordance with the laws of the State of New York and, assuming that the Deposit Agreement is the valid and legally binding obligation of the Depositary, constitutes a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors' rights generally, (ii) general equitable principles (whether considered in a proceeding in equity or at law), (iii) an implied covenant of good faith and fair dealing and (iv) the effects of the possible judicial application of foreign laws or foreign governmental or judicial action affecting creditors' rights, and also subject to the qualification that enforceability of the indemnification provisions of the Deposit Agreement may be limited by considerations of public policy. Upon issuance by the Depositary of the ADRs evidencing ADSs against the deposit of the Underlying Shares (initially in the form of Certificates of Payment) in accordance with the provisions of the Deposit Agreement, the ADRs will be duly and validly issued pursuant to the laws of the State of New York and the persons in whose names such ADRs are registered will be entitled to the rights specified therein and in the Deposit Agreement. (c) The compliance by the Company with all of the provisions of the Underwriting Agreements and the Deposit Agreement will not breach or result in a default by the Company under any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument that is expressly governed by the laws of the State of New York and filed as an exhibit to the Registration Statement, nor will such action violate any United States federal or New York state statute or any order known to such counsel issued pursuant to any United States federal or New York state statute by any court or governmental agency or body having jurisdiction over the Company or any of its subsidiaries or any of their properties. (d) No consent, approval, authorization, order, registration or qualification of or with any United States federal or New York state governmental agency or body or, to the knowledge of such counsel, any United States federal or New York state court is required for the compliance by the Company with all of the provisions of the Underwriting Agreements and the Deposit Agreement, except for the registration under the Act and the Exchange Act of the Shares and the ADSs or the offering and sale thereof, and such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or "blue sky" laws in connection with the purchase and distribution of the Shares and the ADSs by the Underwriters. (e) The statements made in the Prospectuses under the captions "Description of American Depositary Shares," "Shares Eligible for Future Sale" and "Underwriting", insofar as they purport to constitute summaries of the terms of New York state or United States federal statutes or rules and regulations thereunder or English language contracts or other documents therein described, constitute accurate summaries of the terms of such statutes, rules and regulations or contracts and other documents in all material respects. 25 (f) The statements made in the Prospectuses under the caption "Tax Considerations for Investors in Our ADSs or Shares - United States Federal Income Tax Considerations for United States Holders," insofar as they purport to constitute summaries of matters of United States federal tax laws and regulations or legal conclusions with respect thereto, constitute accurate summaries of matters described therein in all material respects. (g) To the knowledge of such counsel, there are no contracts or documents of a character required to be described in the Registration Statement, the ADR Registration Statement or the Prospectuses or to be filed as exhibits to the Registration Statement or the ADR Registration Statement that are not described or filed as required. (h) The Company is not and, after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Prospectuses, will not be an "investment company" within the meaning of and subject to regulation under the United States Investment Company Act of 1940, as amended. (i) The Registration Statement and the ADR Registration Statement have become effective under the Act; any required filing with the Commission of the Prospectuses, and any supplement thereto, pursuant to Rule 424(b) has been made in the manner and within the time period required by Rule 424(b); and, to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement and the ADR Registration Statement has been issued or proceeding for that purpose initiated or threatened by the Commission. (j) Assuming the validity of such actions under the laws of the ROC and any other non-United States jurisdiction (and subject to the limitations and provisions of Sections 1331, 1332 and 1404(a) of Title 28 of the United States Code and Section 510 of the New York Civil Practice Law and Rules), under the laws of the State of New York relating to personal jurisdiction, and pursuant to Section 15 of the Underwriting Agreements and Section 7.6 of the Deposit Agreement, the Company has: (A) validly submitted to the non-exclusive personal jurisdiction of the New York Courts in any action, suit or proceeding arising out of or based upon the Underwriting Agreements or the Deposit Agreement or the transactions contemplated thereby; and (B) validly appointed CT Corporation System in New York, New York as its authorized agent for the purpose described in Section 15 of the Underwriting Agreements and Section 7.6 of the Deposit Agreement; the waiver by the Company of any objection to the venue of any proceeding in the New York Courts is valid (subject to customary limitations under New York state and Federal laws); and service of process effected in the manner set forth in Section 15 of the Underwriting Agreements and Section 7.6 of the Deposit Agreement will be effective under the laws of the State of New York to confer valid personal jurisdiction over the Company. Such opinion may be subject to customary assumptions, qualifications and limitations and, in rendering such opinion, such counsel may state that (i) they do not express any opinion therein concerning any law other than the law of the State of New York and the federal law of the United States of America and (ii) with respect to all matters governed by the 26 laws of the ROC, such counsel understand that the Representatives are relying on the applicable opinion of Russin & Vecchi referred to below. Such opinion shall also include language confirming the extent of such counsel's participation in the preparation of the Registration Statement, the ADR Registration Statement and the Prospectuses and confirming that based on such participation: (i) such counsel are of the opinion that the Registration Statement and the ADR Registration Statement, as of their respective effective dates, and the Prospectuses, as of May 23, 2002, complied as to form in all material respects with the requirements of the Act (except in each case for the financial statements and other financial data contained therein, as to which such counsel need express no opinion); and (ii) such counsel have no reason to believe that the Registration Statement and the ADR Registration Statement, as of their respective effective dates (except in each case for the financial statements and other financial data contained therein, as to which such counsel need express no belief), contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading or that the Prospectuses (except for the financial statements and other financial data contained therein, as to which such counsel need express no belief) contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The foregoing opinion and statement may be qualified by a statement to the effect that such counsel have not independently verified the accuracy, completeness or fairness of the statements made or included in the Registration Statement, the ADR Registration Statement or the Prospectuses and take no responsibility therefor, except as and to the extent set forth in clauses (e) and (f) above. (iii) On each of the Closing Date and any settlement date, the Company and each of Benq Corporation ("Benq"), Acer, Inc. ("Acer") and Kuang-Hwa Investment Holding Co., Ltd.

(g) Neither the execution and delivery by the Company of, the performance by the Company of its obligations under, and the consummation of any of the other transactions contemplated in the Underwriting Agreements and the Deposit Agreement, nor the application of the proceeds from the sale of Underwritten Securities as described in the Prospectuses, will contravene or result in a breach or violation of any provision of applicable laws and regulations of the ROC or the Articles of Incorporation or other constitutive documents of the Company, or, to the best of our knowledge, any agreement or other instrument binding upon the Company that is material to the Company and the Subsidiaries, taken as a whole, or, to the best of our knowledge, any judgment, order or 29 decree of any governmental body, agency or court of the ROC having jurisdiction over the Company or any of the Subsidiaries; neither the execution and delivery by each of Benq, Acer and Kuang-Hwa of, nor the performance by each of Benq, Acer and Kuang-Hwa of, their respective obligations under the Underwriting Agreements and the Powers of Attorney will contravene or result in a breach or violation of any provision of applicable laws and regulations of the ROC or the articles of incorporation or other constitutive documents of Benq, Acer and Kuang-Hwa. (h) We have reviewed the statements in the Prospectuses under the captions "Risk Factors", "Dividends", "Our Business", "Management", "Related Party Transactions", "Description of Our Share Capital", "Description of American Depositary Shares", "The Securities Markets of Taiwan", "Foreign Investment and Exchange Controls in Taiwan", "Shares Eligible for Future Sale", "Enforceability of Civil Liabilities" and "Tax Considerations for Investors in Our ADSs or Shares - ROC Tax Considerations" and confirm that, insofar as such statements constitute summaries of the legal matters, legal documents or legal proceedings referred to therein, to the extent, and only to the extent, governed by the laws of the ROC, fairly present the information called for with respect to such legal matters, documents and proceedings and fairly summarize the matters described therein. (i) Nothing has come to our attention that would lead us to believe that (except for the financial statements and other financial or statistical data contained therein, as to which we need not express any opinion or belief) the Registration Statement or the ADR Registration Statement as of the respective dates thereof contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein not misleading; and the Prospectuses as of their respective dates and as of the date hereof, contained or contain any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. (j) The Underwriting Agreements, the Deposit Agreement, the Certificate of Payment and the documents to be furnished thereunder are in proper legal form under the laws of the ROC for the enforcement thereof against the Company, Benq, Acer and Kuang-Hwa, as applicable, under the laws of the ROC. Except for the filings and registrations referred to in opinion (d) above, it is not necessary, required, or advisable, to ensure the legality, validity, enforceability or admissibility in evidence of any of such agreement or document that such agreement or document be filed or recorded with any court or other authority in the ROC or that any stamp or similar tax be paid, it being understood that in court proceedings in the ROC a translation into Chinese language may be required. (k) None of the parties to the Underwriting Agreements or the Deposit Agreement in order to enforce any of their respective rights under the Underwriting Agreements or the Deposit Agreement or any other document to be furnished thereunder , and none of the holders of the ADSs in order to enforce any of their respective rights under the ADRs or the Deposit Agreement or any other document to be furnished thereunder (other than such parties or holders that are established under the laws of the ROC) need be licensed, qualified or entitled to do business in the ROC 30 (l) None of the parties to the Underwriting Agreements or the Deposit Agreement (other than those parties established under the laws of the ROC) and none of the holders of the ADSs are or will be deemed to be resident, domiciled, carrying on business or, subject to taxation in the ROC or be required to be licensed, qualified or otherwise entitled to do business in the ROC solely by reason of the ownership of the ADSs or the entry into, performance and/or enforcement of the Underwriting Agreements and/or the Deposit Agreement, as applicable. (m) The choice of New York Law to govern the Underwriting Agreements and the Deposit Agreement is a valid choice of law. Under the Law Governing the Application of Laws to Civil Matters Involving Foreign Elements of the ROC (i.e., the ROC conflicts of law rules), if any claim with respect to the obligations of the Company, Benq, Acer or Kuang-Hwa under the Underwriting Agreement or the Deposit Agreement, as applicable comes under the jurisdiction of the ROC courts, New York Law is to be applied. (n) The submission in the Underwriting Agreements and the Deposit Agreement by each of the Company, Benq, Acer and Kuang-Hwa, as applicable, to the non-exclusive jurisdiction of and the irrevocable waiver of objection to venue of a proceeding in the U.S. federal and New York state courts in New York City is valid and binding upon each of the Company, Benq, Acer and Kuang-Hwa. The irrevocable appointment by each of the Company, Benq, Acer and Kuang-Hwa of CT Corporation System in New York as its authorized agent for the purpose described in the Underwriting Agreements and the Deposit Agreement, as applicable, is legal, valid and binding on each of the Company, Benq, Acer and Kuang-Hwa. (o) A judgment obtained against the Company, Benq, Acer or Kuang-Hwa in the courts of the ROC in respect of any sum payable by the Company, Benq, Acer or Kuang-Hwa under the Underwriting Agreements or the Deposit Agreement, as applicable may be expressed in United States dollars or New Taiwan dollars. However, if such judgment is enforced against assets of the Company, Benq, Acer or Kuang-Hwa located in the ROC, the fact that the judgment is rendered and expressed in United States dollars does not, for foreign exchange control purposes, itself, create a right to convert the New Taiwan dollar proceeds of such enforcement into United States dollars. (p) Except as described in the Prospectuses, all cash dividends and other distributions declared and payable on the Common Shares may be paid by the Company to each such holder in New Taiwan dollars that may be converted into foreign currency and freely transferred out of the ROC without the necessity of obtaining any governmental authorizations of, or from, any governmental agency in the ROC. However, the CBC Conversion Filings will be required to be made by the Company in connection with such conversion and transfer and similar filings by holders of Common Shares withdrawn from the ADS facility or their designated agents in the ROC will be required in connection with such conversion and transfer. Other than as described in the Prospectuses, all such dividends and other distributions made to holders of ADSs who are non-residents of the ROC will not be subject to the ROC income, withholding or other taxes under the laws and regulations of the ROC and are otherwise free and clear of any other tax, duty, withholding or deduction in the ROC. 31 (q) To the best of our knowledge, and except as otherwise disclosed in the Prospectuses, (i) the Company owns or possesses or is licensed to use all material patents, patent applications, trademarks, service marks, trade names, licenses, copyrights and proprietary or other confidential information ("Intellectual Property Rights") currently utilized by the Company in connection with its business and proposed to be utilized in connection with its business, and (ii) the Company has not received any notice of material infringement of or conflict with asserted rights of any third party with respect to any Intellectual Property Rights which, if determined adversely to the Company, would have a Material Adverse Effect. (r) To the best of our knowledge, the Company holds all, and is not in material violation of any, ROC governmental licenses and approvals necessary to own its property and conduct its business as described in the Prospectuses except to the extent that the failure to hold such licenses or approvals and/or the violation thereof would not have a Material Adverse Effect. (s) With respect to the Company's obligations and those of Benq, Acer and Kuang-Hwa under the Underwriting Agreements and the Deposit Agreement, as applicable, in the event a judgment of the courts of a country other than the ROC, including without limitation a judgment obtained in a New York court, were obtained, and enforcement of such judgment were sought in the ROC, such judgment would be recognized and enforced by the courts of the ROC without retrial or examination of the merits of the case only if the ROC courts are satisfied that: (i) the court rendering the judgment had subject matter jurisdiction under the laws of the ROC; (ii) the judgment was not contrary to public order or good morals of the ROC; (iii) the judgment was a final judgment for which the period for appeal had expired or from which no appeal could be taken; (iv) if the Company , Benq, Acer or Kuang-Hwa did not appear in the proceedings in such court and a judgment by default was entered, process was served either personally on the Company, Benq, Acer or Kuang-Hwa in the country of litigation or with the assistance of the judicial authorities of the ROC; and (v) judgments of the courts of the ROC would be enforceable in the jurisdiction of the court rendering such judgment on a reciprocal basis. (t) The performance by the Underwriters or the Depositary of any of their respective duties, obligations or responsibilities under the Underwriting Agreements or the Deposit Agreement in the manner contemplated thereby will not violate any applicable ROC law. (u) The voting arrangements set forth under "Description of American Depositary Shares" as described in the Prospectuses and the voting arrangements as set forth in the Deposit Agreement are legal and conform to the requirements of ROC law and constitute a valid and binding agreement by the holders of interests in the ADSs as to their voting rights. (v) The Depositary will not be deemed to be authorized to exercise any discretion when voting in accordance with the Deposit Agreement under ROC law, and the Depositary will not (in the absence of negligence, bad faith or breach of contract, and subject to general principles of agency) be subject to any liability under ROC law for losses 32 arising from the exercise of the voting arrangements set out in the Deposit Agreement on the grounds that voting in accordance with the Deposit Agreement is in violation of ROC law. (w) So long as no single owner of the ADSs holds or owns, as applicable, ADSs (or ADSs, Certificate of Payment and Common Shares in the aggregate) representing more than 10% of the Company's outstanding Common Shares, there will be no reporting obligations under the ROC law on the part of the Depositary or its nominee or owner of the ADSs (i) by virtue of the Depositary being a party to the Deposit Agreement and exercising its rights and performing its obligations thereunder or (ii) in connection with the ADSs and the Certificate of Payment or Common Shares represented by the ADSs. (x) Each of the Company, Benq, Acer and Kuang-Hwa can sue and be sued in its own name under the laws of the ROC and an ROC court would have jurisdiction in any suit, action or proceedings brought against the Company, Benq, Acer and Kuang-Hwa arising out of or in connection with the Underwriting Agreements or the Deposit Agreement, as applicable. (y) Each of Benq, Acer and Kuang-Hwa has been duly incorporated and is validly existing as a corporation under the laws of the ROC. (z) The Underwriting Agreements and the Powers of Attorney have been duly authorized, executed and delivered by each of Benq, Acer and Kuang-Hwa and constitute valid and legally binding obligations of each of Benq, Acer and Kuang-Hwa, enforceable in accordance with the terms thereof. (aa) To the best of our knowledge, the Company is not in violation of the Articles of Incorporation or other constitutive documents or in default in the performance or observance of any material obligation, agreement, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which it is a party or by which it or any of its properties may be bound. (bb) Each of Benq, Acer and Kuang-Hwa has, and immediately prior to the Closing Date or any settlement date, as applicable, will have, full right, power and authority to deposit the Option Shares with the Depositary as contemplated in the Underwriting Agreements and to sell, assign, transfer and deliver the Option Shares in the form of ADSs to be sold by Benq, Acer and Kuang-Hwa under the Underwriting Agreements. (cc) Each of Benq, Acer and Kuang-Hwa is the beneficial owner of the Option Shares to be deposited with the Depositary against issuance of the ADRs evidencing the ADSs to be sold by Benq, Acer and Kuang-Hwa pursuant to the Underwriting Agreements, has, and immediately prior to the Closing Date or any settlement date, as applicable, will have, good and valid title to such Option Shares, in each case free and clear of all liens, encumbrances, equities and claims; and upon delivery of such Option Shares and payment therefor pursuant to the Underwriting Agreements, good and valid title to such Option Shares, free and clear of all liens, encumbrances, equities or claims, will pass to the Depositary or its nominee for the benefit of the several Underwriters. (dd) To the best of our knowledge, the Company has good and marketable title to all real property and good and marketable title to all personal Property owned by them 33 which is material to the business of the Company, in each case free and clear of all liens, encumbrances and defects except such as are described in the Prospectuses or such as do not materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company; and any real property and buildings held under lease by the Company are held under valid, subsisting and enforceable leases with such exceptions as are not material and do not materially interfere with the use made and proposed to be made of such property and buildings by the Company and except as described in the Prospectuses. (ee) The Registration Statement and the Prospectuses have been duly authorized by and on behalf of the Company; the Registration Statements have been signed for and on behalf of the Company by officers thereunto duly authorized and by directors duly elected or appointed. In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the ROC, to the extent they deem proper and specified in such opinion, upon the opinion of other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for the Underwriters and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials. References to the Prospectuses in this paragraph (iii) include any supplements thereto at the Closing Date. (iv) On each of the Closing Date and any settlement date, the Depositary shall have requested and caused Patterson, Belknap, Webb & Tyler LLP, counsel for the Depositary, to have furnished to the Representatives their opinion dated the Closing Date or the settlement date, as the case may be, and addressed to the Representatives, to the effect that: (a) The Deposit Agreement has been duly authorized, executed and delivered by the Depositary and constitutes a legal, valid and binding instrument enforceable against the Depositary in accordance with its terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or other laws affecting creditors' rights generally from time to time in effect); the statements in the Prospectuses under the heading "Description of American Depositary Shares," insofar as such statements purport to describe the Depositary and summarize certain provisions of the Deposit Agreement, the ADSs and the ADRs, are fair and accurate. (b) The Depositary has full power and authority and legal right to execute and deliver the Deposit Agreement and to perform its obligations thereunder. (c) The ADRs and the ADSs evidenced thereby are in valid and sufficient form and, when issued under the Deposit Agreement, the ADRs will be duly and validly issued and will entitle the holders and beneficial owners thereof to the rights specified therein and in the Deposit Agreement. (d) The ADR Registration Statement has become effective under the Act and, to the knowledge of such counsel, no stop order suspending the effectiveness of the ADR Registration Statement has been issued, no proceedings for that purpose 34 have been instituted or threatened, and the ADR Registration Statement, and each amendment comply as to form in all material respects with the applicable requirements of the Act and the rules thereunder. (v) On each of the Closing Date and any settlement date, the Selling Shareholders shall have requested and caused Simpson Thacher & Bartlett, United States counsel for the Selling Shareholders, to have furnished to the Representatives their opinion dated the Closing Date or the settlement date, as the case may be, addressed to the Representatives, to the effect that: (a) The Underwriting Agreements have been duly executed and delivered by or on behalf of the Selling Shareholders in accordance with the laws of the State of New York. (b) The compliance by the Selling Shareholders with all of the provisions of the Underwriting Agreements will not violate any United States federal or New York state statute or any order known to such counsel issued pursuant to any United States federal or New York state statute by any court or governmental agency or body having jurisdiction over any Selling Shareholder. (c) No consent, approval, authorization, order, registration or qualification of or with any United States federal or New York state governmental agency or body or, to the knowledge of such counsel, any United States federal or New York state court is required for the compliance by the Selling Shareholders with all of the provisions of the Underwriting Agreements, except for the registration under the Act and the Exchange Act of the Shares and the ADSs or the offering and sale thereof, and such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or "blue sky" laws in connection with the purchase and distribution of the Shares and the ADSs by the Underwriters. (d) Assuming the validity of such actions under the laws of the ROC and any other non-United States jurisdiction (and subject to the limitations and provisions of Sections 1331, 1332 and 1404(a) of Title 28 of the United States Code and Section 510 of the New York Civil Practice Laws and Rules), under the laws of the State of New York relating to personal jurisdiction, and pursuant to Section 15 of the Underwriting Agreements, each Selling Shareholder has: (A) validly submitted to the non-exclusive personal jurisdiction of the New York Courts in any action, suit or proceeding arising out of or based upon the Underwriting Agreements or the transactions contemplated thereby; and (B) in the case of Benq, Acer and Kuang-Hwa, validly appointed CT Corporation System in New York, New York, and in the case of UMC (as defined below), validly appointed Law+, P.C., as its authorized agent for the purpose described in Section 15 of the Underwriting Agreements, the waiver by each Selling Shareholder of any objection to the venue of any proceeding in the New York Courts is valid (subject to customary limitations under New York state and federal laws), and service of process effected in the manner set forth in Section 15 of the Underwriting Agreements will be effective under the laws of the State of New York to confer valid personal jurisdiction over such Selling Shareholder. 35 (e) Upon payment for and transfer of the security entitlements to the ADSs representing Option Shares as contemplated in the Underwriting Agreements, DTC will be a protected purchaser who acquires its interest free of any adverse claim (within the meaning of Section 8-303 of the New York UCC), and an action based on an adverse claim to the security entitlements to such ADSs may not be asserted against the Underwriters. The opinion of such counsel may be subject to customary assumptions, qualifications and limitations and, in rendering such opinion, such counsel may state that (i) they do not express any opinion therein concerning any law other than the law of the State of New York and the federal law of the United States of America and (ii) with respect to all matters governed by the laws of the ROC, such counsel understand that the Representatives are relying on an opinion of Russin & Vecchi. References to the Prospectuses in this paragraph (v) include any supplements thereto at the Closing Date. (vi) On each of the Closing Date and any settlement date, United Microelectronics Corporation ("UMC") shall have requested and caused Chen & Lin, ROC counsel for UMC as a Selling Shareholder, to have furnished to the Representatives their opinion dated the Closing Date or the settlement date, as the case may be, addressed to the Representatives, to the effect that: (a) UMC has been duly incorporated and is validly existing as a corporation under the laws of the ROC. (b) The Underwriting Agreements and the Power of Attorney of UMC have been duly authorized, executed and delivered by UMC and constitute valid and legally binding obligations of UMC enforceable in accordance with the terms thereof, and UMC has the full legal right and authority to sell, transfer and deliver the Option Shares in the form of ADSs to be sold by UMC under the Underwriting Agreements. (c) UMC is the beneficial owner of the Option Shares to be deposited by UMC with the Depositary against issuance of the ADRs evidencing the ADSs to be sold by UMC hereunder, and has, and immediately prior to the Closing Date or any settlement date will have, good and valid title to such Option Shares, in each case free and clear of all liens, encumbrances, equities and claims. (d) Upon delivery of the Option Shares to be purchased from UMC, and payment therefor, pursuant to the Underwriting Agreements, good and valid title to such Option Shares, free and clear of all liens, encumbrances, equities or claims, will pass to the Depositary or its nominee for the benefit of the several Underwriters; assuming the Deposit Agreement has been duly authorized and delivered by the parties thereto, the Option Shares to be deposited by UMC may be freely deposited with the Depositary against issuance of ADRs evidencing ADSs and the ADSs delivered at the settlement date will be freely transferable by UMC to or for the account of the several Underwriters and (to the extent described in the Prospectuses) the initial purchasers thereof; and there are no restrictions on subsequent transfers of the Option Securities to be sold by UMC except as described in the Prospectuses 36 under the captions "Description of Our Share Capital," "Description of American Depositary Shares" or "Foreign Investment and Exchange Controls in Taiwan". (e) No consent, approval, authorization, filing with, or order of, or qualification with, any governmental body or agency of the government of the ROC is required in connection with the transactions contemplated in the Underwriting Agreements or in the Deposit Agreement, except for (i) the approvals of the CBC and reports to the CBC of the foreign exchange settlements and payments contemplated by the Deposit Agreement (the "CBC Conversion Filings"); (ii) the filings and approvals, if any, required under (A) the "Guidelines For Handling Issuance and Offer of Overseas Securities by Issuers of the ROC (the "Overseas Offering Rules"), and (B) the rules and regulations of the Taiwan Stock Exchange, the ROC SFC and the CBC; (iii) completion of the corporate amendment registration reflecting the issuance of the Underwritten Shares with the SIPA which registration is required to be filed by the Company with fifteen (15) days after the Closing Date and (iv) the approvals which have been obtained under the laws of the ROC and are in full force and effect as of the date hereof, including the SIPA Approval, the CBC Approvals and the ROC SFC Approvals (f) None of the execution and delivery of the Power of Attorney of UMC or of the Underwriting Agreements by UMC, and the performance by UMC of its obligations under the Underwriting Agreements and the Power of Attorney of UMC, will conflict with, or result in a breach or violation of, any applicable laws of the ROC or the articles of incorporation or any other constitutive documents of UMC. (g) The choice of law provision set forth in Section 15 of the Underwriting Agreements will be recognized by the courts of the ROC and such counsel knows of no reason why the courts of the ROC would not give effect to the choice of New York law as the proper law of the Underwriting Agreements, provided that the relevant provisions of the laws of the State of New York will not be applied to the extent such courts hold that such provisions of the laws of the State of New York are contrary to the public order or good morals of the ROC and an ROC court would have jurisdiction in any suit, action or proceedings brought against UMC arising out of or in connection with the Underwriting Agreements; UMC has the legal capacity to sue and be sued in its own name under the laws of the ROC; UMC has validly and irrevocably appointed Law+, P.C. as its authorized agent for the purpose described in Section 15 of the Underwriting Agreements under the laws of the ROC; the irrevocable submission of UMC to the non-exclusive jurisdiction of the New York Courts and the waivers by UMC of any objection to the venue of the proceeding in a New York Court in the Underwriting Agreements are legal, valid and binding under the laws of the ROC; and any final and conclusive judgment against UMC obtained in a New York Court arising out of or in relation to the obligations of UMC under the Underwriting Agreements would be enforceable against UMC in the courts of the ROC, provided that the court of the ROC in which the enforcement is sought is satisfied that (A) the court rendering the judgment had jurisdiction over the subject matter according to the laws of the ROC, (B) the judgment is not contrary to the public order or good morals of the ROC, (C) if the judgment was rendered by default by the court rendering the judgment, UMC was served while within the jurisdiction of 37 such court or process was served on UMC with judicial assistance of the ROC; and (D) judgments of the courts of the ROC are recognized and enforceable in the court rendering the judgment on a reciprocal basis. (h) A judgment obtained against UMC in the courts of the ROC in respect of any sum payable by UMC under the Underwriting Agreements or the Deposit Agreement, as applicable may be expressed in United States dollars or New Taiwan dollars. (i) The Underwriting Agreements and the documents to be furnished thereunder are in proper legal form under the laws of the ROC for the enforcement thereof against UMC, as applicable, under the laws of the ROC. Except for the filings and registrations referred to in paragraph (e) above, it is not necessary, required, or advisable, to ensure the legality, validity, enforceability or admissibility in evidence of any of such agreement or document that such agreement or document be filed or recorded with any court or other authority in the ROC or that any stamp or similar tax be paid, it being understood that in court proceedings in the ROC a translation into Chinese language may be required. In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the ROC, to the extent they deem proper and specified in such opinion, upon the opinion of other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for the Underwriters and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials. References to the Prospectuses in this paragraph (vi) include any supplements thereto at the Closing Date. (vii) On each of the Closing Date and any settlement date, the Representatives shall have received from Davis Polk & Wardwell, United States counsel for the Underwriters, such opinion or opinions, dated the Closing Date or the settlement date, as the case may be, addressed to the Representatives, with respect to the issuance and sale of the Securities, the Registration Statement, the ADR Registration Statement, the Prospectuses (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Company and each Selling Shareholder shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters. (viii) On each of the Closing Date and any settlement date, the Representatives shall have received from Lee & Li, ROC counsel for the Underwriters, such opinion or opinions, dated the Closing Date or the settlement date, as the case may be, and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Registration Statement, the ADR Registration Statement, the Prospectuses (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Company and each Selling Shareholder shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters. (ix) On each of the Closing Date and any settlement date, the Company shall have furnished to the Representatives a certificate of the Company, signed by the Chairman of the 38 Board or the President and the principal financial or accounting officer of the Company, dated the Closing Date or the settlement date, as the case may be, to the effect that the signers of such certificate have carefully examined the Registration Statement, the ADR Registration Statement, the Prospectuses, any supplements to the Prospectuses and this Agreement and that: (a) The representations and warranties of the Company in the Underwriting Agreements are true and correct on and as of the Closing Date or the settlement date, as the case may be, with the same effect as if made on the Closing Date or the settlement date, as the case may be, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied under the Underwriting Agreements at or prior to the Closing Date or the settlement date, as the case may be. (b) No stop order suspending the effectiveness of the Registration Statement or the ADR Registration Statement has been issued and no proceedings for that purpose have been instituted or, to the Company's knowledge, threatened. (c) Since the date of the most recent financial statements included in the Prospectuses (exclusive of any supplement thereto), there has not been any change, or any development involving a prospective change, that would have a material adverse effect on the condition (financial or otherwise), earnings, business or properties of the Company and the Subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Prospectuses (exclusive of any supplement thereto). (x) On each of the Closing Date and any settlement date, each Selling Shareholder shall have furnished to the Representatives a certificate, signed by a duly authorized signatory dated the Closing Date or the settlement date, as the case may be, to the effect that the signer of such certificate has carefully examined the Registration Statement, the ADR Registration Statement, the Prospectuses, any supplement to either of the Prospectuses and this Agreement and the U.S. Underwriting Agreement and that the representations and warranties of such Selling Shareholder in this Agreement and the U.S. Underwriting Agreement are true and correct in all material respects on and as of the Closing Date or the settlement date, as the case may be, to the same effect as if made on the Closing Date, or the settlement date, as the case may be. (xi) The Company shall have requested and caused KPMG to have furnished to the Representatives letters, dated respectively as of the Execution Time as of the Closing Date, and as of any settlement date, in form and substance satisfactory to the Representatives, confirming that they are independent accountants within the meaning of the Act and the applicable rules and regulations adopted by the Commission thereunder and that they have performed a review of the unaudited interim financial information of the Company for the three-month period ended March 31, 2002 and as at March 31, 2002, in accordance with generally accepted auditing standards applicable in the ROC and statement on Auditing Standards No. 71, provided that the letter delivered on the Closing Date shall use a "cut-off" date not earlier than the date hereof and the letter delivered on any settlement date shall use a 39 "cut off" date not earlier than the date of the third Business Day prior to such settlement date, and stating in effect that: (a) In their opinion the audited financial statements and financial statement schedules included in the Registration Statement and the Prospectuses and reported on by them comply as to form in all material respects with the applicable accounting requirements of generally accepted accounting principles in the ROC and the applicable accounting requirements of the Act and the related rules and regulations adopted by the Commission; and all necessary adjustments to net income and shareholders' equity for the periods presented that would be required if U.S. generally accepted accounting principles had been applied have been made. (b) On the basis of a reading of the latest unaudited financial statements made available by the Company and the Subsidiaries; their limited review, in accordance with generally accepted auditing standards applicable in the ROC and standards established under Statement on Auditing Standards No. 71, of the unaudited interim financial information for the three-month period ended March 31, 2002, and as at March 31, 2002; carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading of the minutes of the meetings of the stockholders and directors of the Company and the Subsidiaries; and inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company and the Subsidiaries as to transactions and events subsequent to December 31, 2001, nothing came to their attention which caused them to believe that: (i) any unaudited financial statements included in the Registration Statement and the Prospectuses do not comply as to form in all material respects with generally accepted accounting principles and the regulations in the ROC and applicable accounting requirements of the Act and with the related rules and regulations adopted by the Commission with respect to registration statements on Form F-1; and said unaudited financial statements are not in conformity with generally accepted accounting principles applied on a basis substantially consistent with that of the audited financial statements included in the Registration Statement and the Prospectuses; and all necessary adjustments to net income and shareholders' equity for such interim period that would be required if U.S. generally accepted accounting principles had been applied have not been made. (ii) with respect to the period subsequent to March 31, 2002, there were any changes, at a specified date not more than five days prior to the date of the letter, in the long-term debt of the Company and the Subsidiaries or capital stock of the Company or decreases in the consolidated net current assets or stockholders' equity of the Company as compared with the amounts shown on the March 31, 2002, consolidated balance sheet included in the Registration Statement and the Prospectuses, or for the period from April 1, 2002 to such specified date there were any decreases, as compared with the corresponding period in the preceding year in 40 consolidated net sales or in the total or per-share amounts of net income of the Company and the Subsidiaries, except in all instances for changes or decreases set forth in such letter, in which case the letter shall be accompanied by an explanation by the Company as to the significance thereof unless said explanation is not deemed necessary by the Representatives. (c) They have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Company and its subsidiaries) set forth in the Registration Statement and the Prospectuses, including the information set forth under the captions "Prospectus Summary - Summary Financial and Operational Data" and "Selected Financial and Operational Data" in the Prospectuses, agrees with the accounting records of the Company and its subsidiaries, excluding any questions of legal interpretation. (d) On the basis of a reading of the unaudited pro forma financial statements included in the Registration Statement and the Prospectuses (the "pro forma financial statements"); carrying out certain specified procedures; inquiries of certain officials of the Company and Unipac Optoelectronics Corporation, who have responsibility for financial and accounting matters; and proving the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in the pro forma financial statements, nothing came to their attention which caused them to believe that the pro forma financial statements do not comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X or that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of such statements. (xii) The Company shall have requested and caused Diwan, Ernst & Young to have furnished to the Representatives letters, dated respectively as of the Execution Time, as of the Closing Date, and as of any settlement date, in form and substance satisfactory to the Representatives, confirming that they are independent accountants within the meaning of the Act and the applicable rules and regulations adopted by the Commission thereunder and containing other statements and information of the type ordinarily included in accountants' "comfort letters" to underwriters with respect to the financial statements of Unipac Optoelectronics Corporation and certain financial information contained in the Registration Statement and the Prospectuses, provided that the letter delivered on the Closing Date shall use a "cut-off" date not earlier than the date hereof and the letter delivered on any settlement date shall use a "cut off" date not earlier than the date of the third Business Day prior to such settlement date.

(xiv) The Company and the Depositary shall have executed and delivered the Deposit Agreement, and the Selling Shareholders shall have executed and delivered the Power of Attorney, in each case in form and substance satisfactory to the Representatives, and each of the Deposit Agreement and the Powers of Attorney shall be in full force and effect. (xv) The Selling Shareholders shall have delivered to the Depositary, no later than on the Deposit Date, a New Taiwan dollar Bank of Taiwan cheque payable to the ROC taxing authority, dated as of such date of delivery, in the amount of the securities transfer tax payable on the transfer on the Closing Date or the settlement date, as the case may be, of the Option Shares represented by the ADSs to be sold by the Selling Shareholders pursuant to the Underwriting Agreements to the appropriate taxing authorities in the Republic of China. (xvi) The Depositary shall have furnished or caused to be furnished to the Representatives certificates satisfactory to the Representatives evidencing (i) the deposit with the Depositary of the Certificates of Payment or Option Shares in respect of which ADSs to be purchased by the Underwriters on the Closing Date or any settlement date, as the case may be, are to be issued, (ii) the execution, issuance, countersignature (if applicable) and delivery of the ADRs evidencing such ADSs pursuant to the Deposit Agreement, (iii) if applicable, the receipt by the Depositary of the New Taiwan dollar Bank of Taiwan cheque referred to in Section 6(xv) hereof, and (iv) such other matters related thereto as the Representatives reasonably request.

(xviii) The ADSs shall have been listed and admitted and authorized for trading on the New York Stock Exchange, subject only to official notice of issuance, and satisfactory evidence of such actions shall have been provided to the Representatives. (xix) At the Execution Time, the Company shall have furnished to the Representatives a letter substantially in the form of Exhibit A hereto from each executive officer of the Company listed in the Prospectuses, and the legal entity represented by each director and supervisor of the Company, in each case addressed to the Representatives. (xx) No order or notice, oral or written, from any governmental or regulatory authority of the ROC, including the ROC SFC, has been received by the Company to the effect that the offering contemplated by this Agreement, if consummated, will contravene applicable laws or regulations of the ROC. 42 (xxi) Prior to the Closing Date, the Company shall have received from each of its employees entitled to subscribe to the Underwritten Shares a written waiver of such employee's right to subscribe to such Underwritten Shares. (xxii) The closing of the purchase of the U.S. Underwritten Securities to be issued and sold by the Company and the Selling Shareholders pursuant to the U.S. Underwriting Agreement shall occur concurrently with the closing of the purchase of the International Underwritten Securities described herein.

Notice of such cancellation shall be given to the Company and each Selling Shareholder in writing or by telephone or facsimile confirmed in writing. The documents required to be delivered by this Section 6 shall be delivered at the office of Davis Polk & Wardwell, counsel for the Underwriters, at 18/F, The Hong Kong Club Building, 3A Chater Road, Hong Kong, on the Closing Date. 7. Reimbursement of Underwriters' Expenses. If the sale of the International Securities provided for in this Agreement is not consummated: (a) Because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied because of any refusal, inability or failure of the Company to comply with such condition, or because of any refusal, inability or failure on the part of the Company to perform any agreement in this Agreement or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Underwriters shall not be required to make any payments, or reimburse the Company or the Selling Shareholders for any payments, described in Section 5(i)(o) hereof, and the Company will reimburse the Underwriters severally through Salomon Smith Barney Inc. on demand for (i) all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities and (ii) all payments by the Underwriters under Section 5(i)(o) hereof.

(c) For any reason other than those set forth in paragraphs (a) or (b) above, the Underwriters will not be required to make any payments, or reimburse the Company or the Selling Shareholders for any payments, described in Section 5(i)(o) hereof, and the Company will reimburse the Underwriters severally through Salomon Smith Barney Inc. on demand for all payments by the Underwriters under Section 5(i)(o) hereof. If the Company is required to make any payments to the Underwriters under this Section 7 because of any Selling Shareholder's refusal, inability or failure to satisfy any condition to the obligations of the Underwriters set forth in Section 6, the Selling Shareholders shall reimburse the Company pro rata in proportion to the percentage of Securities to be sold by each on demand for all amounts so paid. 8. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each International Underwriter, the directors, officers, employees and agents of each International Underwriter and each person who controls any International Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Securities as originally filed or in any amendment thereof, or in the ADR Registration Statement as originally filed or in any amendment thereof, or in any U.S. or International Preliminary Prospectus or in either of the Prospectuses, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any International Underwriter through the International Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have. (b) Each Selling Shareholder severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement or the ADR Registration Statement, each International Underwriter, the directors, officers, employees and agents of each International Underwriter and each person who controls the Company or any International Underwriter within the meaning of either the Act or the Exchange Act and each other 44 Selling Shareholder, if any, to the same extent as the foregoing indemnity from the Company to each International Underwriter, but only with reference to written information furnished to the Company by or on behalf of such Selling Shareholder specifically for inclusion in the documents referred to in the indemnity in Section 8(a). This indemnity agreement will be in addition to any liability which any Selling Shareholder may otherwise have. (c) Each International Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement or the ADR Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act and each Selling Shareholder, to the same extent as the indemnity in Section 8(a) from the Company to each International Underwriter, but only with reference to written information relating to such International Underwriter furnished to the Company by or on behalf of such International Underwriter through the Representatives specifically for inclusion in the documents referred to in the indemnity in Section 8(a). This indemnity agreement will be in addition to any liability which any International Underwriter may otherwise have. The Company and each Selling Shareholder acknowledge that the statements set forth in the last paragraph of the cover page regarding delivery of the Securities, and, under the heading "Underwriting," (i) the list of Underwriters and their respective participation in the sale of the Securities, (ii) the sentences related to concessions and reallowances, and (iii) the paragraph related to stabilization, syndicate covering transactions and penalty bids in any U.S. or International Preliminary Prospectus and the Prospectuses, constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any U.S. or International Preliminary Prospectus or the Prospectuses. (d) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a), (b) or (c) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a), (b) or (c) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying 45 party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either the Act or the Exchange Act and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Shareholders and all persons, if any, who control any Selling Shareholder within the meaning of either the Act or the Exchange Act, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and directors, officers, employees and agents, and control persons, of any Underwriters, such firm shall be designated in writing by Salomon Smith Barney Inc. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Shareholders and such control persons of any Selling Shareholders, such firm shall be designated in writing by the persons named as attorneys-in-fact for the Selling Shareholders under the Powers of Attorney. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought under this Agreement (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. (e) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company, the Selling Shareholders and the International Underwriters agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Company, one or more of the Selling Shareholders and one or more of the International Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company, by the Selling Shareholders and by the International 46 Underwriters from the offering of the International Securities; provided, however, that in no case shall any International Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the International Securities purchased by such International Underwriter under this Agreement. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company, the Selling Shareholders and the International Underwriters shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, of the Selling Shareholders and of the International Underwriters in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company and by the Selling Shareholders shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by each of them, and benefits received by the International Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the International Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company and the Selling Shareholders on the one hand or the International Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Selling Shareholders and the International Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (e), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an International Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an International Underwriter shall have the same rights to contribution as such International Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement or the ADR Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (e). 9. Default by an Underwriter. If any one or more International Underwriters shall fail to purchase and pay for any of the International Securities agreed to be purchased by such International Underwriter or International Underwriters under this Agreement and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining International Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of International Securities set forth opposite their names in Schedule I hereto bears to the aggregate amount of International Securities set forth opposite the names of all the remaining International Underwriters) the International Securities which the defaulting International Underwriter or International 47 Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of International Securities which the defaulting International Underwriter or International Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of International Securities set forth in Schedule I hereto, the remaining International Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the International Securities, and if such nondefaulting International Underwriters do not purchase all the International Securities, this Agreement will terminate without liability to any nondefaulting International Underwriter, the Selling Shareholders or the Company. In the event of a default by any International Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the International Representatives shall determine in order that the required changes in the Registration Statement, the ADR Registration Statement and the Prospectuses or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting International Underwriter of its liability, if any, to the Company, the Selling Shareholders and any nondefaulting International Underwriter for damages occasioned by its default under this Agreement. 10. Termination. This Agreement shall be subject to termination in the absolute discretion of the International Representatives, by notice given to the Company prior to delivery of and payment for the International Securities, if at any time prior to such time (i) trading in the Company's Common Shares shall have been suspended by the Commission or the Taiwan Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on either of such Exchanges, (ii) a banking moratorium shall have been declared by U.S. Federal, New York State or the ROC authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States or the ROC of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the International Representatives, impractical or inadvisable to proceed with the offering or delivery of the International Securities as contemplated by the International Prospectus (exclusive of any supplement thereto). 11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers, of each Selling Shareholder and of the International Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any International Underwriter, any Selling Shareholder or the Company or any of the officers, directors or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the International Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement. 12. Notices.

Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York. 15. Jurisdiction. Each of the Company and the Selling Shareholders agrees that any suit, action or proceeding against the Company brought by any International Underwriter, the directors, officers, employees and agents of any International Underwriter, or by any person who controls any International Underwriter, arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any New York Court, and waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding. Each of the Company and each Selling Shareholder other than UMC has appointed CT Corporation System, Inc., 111 Eighth Avenue, New York, New York 10011 as its authorized agent and UMC has appointed Law+, P.C., 993 Highland Circle, Los Altos, CA 94024 as its authorized agent (the "Authorized Agent") upon whom process may be served in any suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated herein which may be instituted in any New York Court, by any International Underwriter, the directors, officers, employees and agents of any International Underwriter, or by any person who controls any International Underwriter, and expressly accepts the non-exclusive jurisdiction of any such court in respect of any such suit, action or proceeding. Each of the Company and the Selling Shareholders hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and the Company agrees to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Company and the Selling Shareholders. Notwithstanding the foregoing, any action arising out of or based upon this Agreement may be instituted by any International Underwriter, the directors, officers, employees and agents of any International Underwriter, or by any person who controls any International Underwriter, in any court of competent jurisdiction in the ROC. The provisions of this Section 15 shall survive any termination of this Agreement, in whole or in part. 16. Currency. Each reference in this Agreement to U.S. Dollars (the "relevant currency") is of the essence. To the fullest extent permitted by law, the obligations of each of the Company and the Selling Shareholders in respect of any amount due under this Agreement will, notwithstanding any payment in any other currency (whether pursuant to a judgment or otherwise), be discharged only to the extent of the amount in the relevant currency that the 49 party entitled to receive such payment may, in accordance with its normal procedures, purchase with the sum paid in such other currency (after any premium and costs of exchange) on the Business Day immediately following the day on which such party receives such payment. If the amount in the relevant currency that may be so purchased for any reason falls short of the amount originally due, the Company or the Selling Shareholder making such payment will pay such additional amounts, in the relevant currency, as may be necessary to compensate for the shortfall. Any obligation of any of the Company or the Selling Shareholders not discharged by such payment will, to the fullest extent permitted by applicable law, be due as a separate and independent obligation and, until discharged as provided herein, will continue in full force and effect. 17. Waiver of Immunity. To the extent that any of the Company or the Selling Shareholders has or hereafter may acquire any immunity (sovereign or otherwise) from any legal action, suit or proceeding, from jurisdiction of any court or from set-off or any legal process (whether service or notice, attachment in aid or otherwise) with respect to itself or any of its property, each of the Company and the Selling Shareholders hereby irrevocably waives and agrees not to plead or claim such immunity in respect of its obligations under this Agreement. 18.
