          Agreement and (D) the consummation of the transactions contemplated
          under the Exchange Offer, except such as may be required by the
          securities or Blue Sky laws of the State of New York;

               (vii)   Such counsel has considered the statements relating to
          United States Federal and New York State legal matters and documents
          governed by New York State law included in the Prospectus under the
          captions "Exchange Offer", "Description of American Depositary
          Receipts", "Taxation -- United States Federal Income Taxation" and
          "Underwriting"; and in such counsel's opinion, such statements, fairly
          summarize in all material respects such matters and documents;

               (viii)  The Company is not, and after giving effect to the
          offering and sale of the ADSs and the application of the proceeds
          thereof as described in the Prospectus will not, be required to
          register as an "investment company" as such term is defined in the
          Investment Company Act;

               (ix)    Nothing has come to such counsel's attention that causes
          such counsel to believe that (A) the Registration Statement and
          Prospectus (except for the financial statements and financial
          schedules and other financial data included therein, as to which such
          counsel need not express a belief) do not comply as to form in all
          material respects with the requirements of the Act and the applicable
          rules and regulations of the Commission thereunder or (B) (x) the
          Registration Statement and the Prospectus included therein (except for
          the financial statements and financial schedules and other financial
          data included therein, as to which such counsel need not express a
          belief) at the time the Registration Statement became effective
          contained an untrue statement of a material fact or omitted to state a
          material fact required to be stated therein or necessary to make the
          statements therein not misleading or (y) the Prospectus (except for
          the financial statements and financial schedules and other financial
          data included therein, as to which such counsel need not express a
          belief) as of its date and as of such Time of Delivery contains an
          untrue statement of a material fact or omitted or omits to state a
          material fact necessary in order to make the statements therein, in
          the light of the circumstances under which they were made, not
          misleading; and

               (x)     Such counsel does not know of any documents that are
          required to be filed as exhibits to the Registration Statement that
          are not filed.

     In rendering such opinion, such counsel may state that they express no
opinion as to the laws of any jurisdiction other than the laws of the State of
New York and the Federal law of the United States;

          (d)  Lee and Li, ROC counsel for the Company, shall have furnished to
     you their written opinion dated such Time of Delivery, in form and
     substance satisfactory to you, to the effect that:

               (i)      The Company has been duly incorporated and is validly
          existing as a corporation limited by shares formed under the laws of
          the ROC, with power and authority (corporate and other) to own its
          properties and conduct its business as described in the Prospectus;

          forth in the Prospectus, and all of the issued shares of capital stock
          of the Company (including the Shares being delivered at such Time of
          Delivery) have been duly and validly authorized and issued and are
          fully paid and non_assessable; all of the issued and outstanding
          Common Shares have been duly listed and admitted for trading on the
          Taiwan Stock Exchange; the holders of outstanding shares of capital
          stock of the Company are not entitled to preemptive or other rights to
          acquire the Shares or the ADSs in connection with the transactions

          Company may be freely deposited by the Company with the Depositary
          against issuance of ADRs evidencing ADSs and, after obtaining the
          approval of the Taiwan Stock Exchange, will be duly listed and
          admitted for trading on the Taiwan Stock Exchange upon the exchange of
          the Certificates of Payment with the Shares; the ADSs and the Shares

               (iii)    The Deposit Agreement has been duly authorized, executed
          and delivered by the Company and constitutes a valid and legally
          binding agreement of the Company, enforceable in accordance with its
          terms, subject, as to enforcement, to bankruptcy, fraudulent transfer,
          insolvency, reorganization and similar laws of general applicability
          relating to or affecting creditors' rights;

               (iv)     To the best of such counsel's knowledge after reasonable
          inquiry and based on a certificate of the Company, the Company has
          been duly qualified as a foreign corporation for the transaction of
          business under the laws of each other jurisdiction in which it owns or
          leases properties or conducts any business so as to require such
          qualification, or is subject to no material liability or disability by
          reason of failure to be so qualified in any such jurisdiction (such
          counsel being entitled to rely in respect of the opinion in this
          clause upon opinions of local counsel and in respect of matters of
          fact upon certificates of officers of the Company, provided that such
          counsel shall state that they believe that both you and they are
          justified in relying upon such opinions and certificates);

               (v)      To the best of such counsel's knowledge after reasonable
          inquiry and based on a certificate of the Company, the Company has
          good and marketable title to all real property owned by it, in each
          case free and clear of all liens, encumbrances and defects except such
          as are described in the Prospectus or such as do not materially affect
          the value of such property and do not 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 by it
          under valid, subsisting and enforceable leases with such exceptions as
          are not material and do not interfere with the use made and proposed
          to be made of such property and buildings by the Company;

<PAGE>   22
               (vi)     To the best of such counsel's knowledge after reasonable
          inquiry and based on a certificate of the Company, other than as set
          forth in the Prospectus, there are no legal or governmental
          proceedings pending to which the Company or any of its Significant
          Subsidiaries is a party or of which any property of the Company or any
          of its Significant Subsidiaries is the subject which, if determined
          adversely to the Company or any of its Significant Subsidiaries, would
          individually or in the aggregate have a material adverse effect on the
          current or future consolidated financial position, shareholders'
          equity or results of operations of the Company and its Significant
          Subsidiaries; and, to the best of such counsel's knowledge, no such
          proceedings are threatened or contemplated by any Governmental Agency
          or threatened by others;

               (vii)    This Agreement has been duly authorized, executed and
          delivered by the Company;

               (viii)   The issue and sale of the Shares and ADSs being
          delivered at such Time of Delivery to be sold by the Company, the
          deposit of the Shares being deposited by the Company with the
          Depositary against issuance of the ADSs evidencing the ADRs to be
          delivered at such Time of Delivery by the Company, the compliance by
          the Company with all of the provisions of this Agreement and the
          Deposit Agreement, the consummation of the transactions herein and
          therein contemplated and the consummation of the transactions
          contemplated under the Exchange Offer will not conflict with or result
          in a breach or violation of any of the terms or provisions of, or
          constitute a default under, any indenture, mortgage, deed of trust,
          loan agreement or other agreement or instrument listed as an exhibit
          to the Registration Statement, nor will such action result in any
          violation of the provisions of the Articles of Incorporation of the
          Company or any statute or any order, rule or regulation of any
          Governmental Agency of the ROC;

               (ix)     No Governmental Authorization of or with any
          Governmental Agency is required in the ROC for the issue and sale of
          the Shares and ADSs by the Company, the deposit of the Shares being
          deposited by the Company with the Depositary against issuance of the
          ADSs evidencing the ADRs to be delivered at such Time of Delivery by
          the Company or the consummation by the Company of the transactions
          contemplated by this Agreement, the Deposit Agreement and the Exchange
          Offer, except for (A) the approval of the CBC of foreign exchange
          settlements and payments contemplated by the Deposit Agreement, (B)
          the filings and approvals, if any, required under (1) the Overseas
          Offering Rules, (2) the rules and regulations of the Taiwan Stock
          Exchange, the SFC or the CBC and (3) the Export Processing Zone
          Administration of the MOEA; and (C) the registration of the issue of
          the Firm Shares with the MOEA, which shall be filed by the Company
          within 15 days of the First Time of Delivery. Such Governmental
          Authorizations which have been obtained are in full force and effect;

               (x)      The statements in the Prospectus under "Risk Factors",

          and "Annex B -- Foreign Investment and Exchange Controls in the ROC",
          to the extent such  statements  relate to matters of law or regulation
          or to the  provisions  of documents  therein  described,  are true and
          accurate in all material  respects,  and nothing has been omitted from
          such  statements  which would make the same misleading in any material
          respect;

               (xi)     To the best of such counsel's knowledge after reasonable
          inquiry and based on the certificates of the Company and the
          Subsidiary, the Company and the Significant Subsidiaries own and
          possess the Intellectual Property necessary to conduct their
          businesses as presently conducted and as proposed to be conducted; and
          neither the Company nor its Significant Subsidiaries has received any
          notice or claim of infringement of or conflict with asserted rights of
          others with respect to any Intellectual Property, which notice or
          claim remains in dispute and which is reasonably likely to have a
          material adverse effect on the current or future consolidated
          financial position, shareholders' equity or results of operations of
          the Company and its Significant Subsidiaries, taken as a whole;

               (xii)    Other than as set forth in the Prospectus, so long as
          this Agreement, the Certificates of Payment and the cross receipt
          referred to in the Deposit Agreement, if any, are executed outside the
          ROC, no stamp or other issuance or transfer taxes or duties and no
          capital gains, income, withholding or other taxes (except such income
          taxes as may be imposed by the government of the ROC or any political
          subdivision or taxing authority thereof or therein on payments
          hereunder to any Underwriter whose net income is subject to tax by the
          ROC or withholding, if any, with respect to any such income tax) are
          payable by or on behalf of the Underwriters to the ROC or to any
          political subdivision or taxing authority thereof or therein in
          connection with (A) the deposit with the Depositary of Shares
          (initially in the form of the Certificates of Payment) by the Company
          against the issuance of ADRs evidencing the ADSs, (B) the sale and
          delivery by the Company of the Shares and ADSs to or for the
          respective accounts of the Underwriters pursuant to the terms of this
          Agreement, (C) the sale and delivery outside the ROC by the
          Underwriters of the ADSs to the initial purchasers thereof in the
          manner contemplated herein, (D) the execution and delivery of this
          Agreement or (E) the consummation of the transactions contemplated
          under the Exchange Offer;

               (xiii)   Insofar as matters of law of the ROC are concerned, the
          Registration Statement and the F-4 Registration Statement and the
          filing of the Registration Statement and the F-4 Registration
          Statement with the Commission have been duly authorized by and on
          behalf of the Company; and the Registration Statement and the F-4
          Registration Statement have been duly executed pursuant to such
          authorization by and on behalf of the Company;

               (xiv)    The Company's agreement to the choice of law provisions
          set forth in Section 17 hereof will be recognized by the courts of the
          ROC; the Company can sue and be sued in its own name under the laws of
          the ROC; the irrevocable submission of the Company to the exclusive
          jurisdiction of a New York Court, the waiver by the Company of any
          objection to the venue of a proceeding of a New York Court and the
          agreement of the Company that this Agreement shall be governed by and
          construed in accordance with the laws of the State of New York


                                      -23-

          are legal, valid and binding; service of process effected in the
          manner set forth in Section 14 hereof will be effective, insofar as
          the law of the ROC is concerned, to confer valid personal jurisdiction
          over the Company; and judgment obtained in a New York Court arising
          out of or in relation to the obligations of the Company under this
          Agreement would be enforceable against the Company in the courts of
          the ROC;

               (xv)     The indemnification and contribution provisions set
          forth in Section 8 hereof do not contravene the laws of the ROC;

               (xvi)    Except as described in the Prospectus all dividends and
          other distributions declared and payable on the shares of capital
          stock of the Company may under the current laws and regulations of the
          ROC to be paid in New Taiwan Dollars (including any such dividends or
          distributions to be paid to the Depositary) may be converted into
          foreign currency that may be freely transferred out of the ROC, and
          all such dividends and other distributions will not be subject to
          withholding or other taxes under the laws and regulations of the ROC
          and are otherwise free and clear of any other tax, withholding or
          deduction in the ROC and without the necessity of obtaining any
          Governmental Authorization in the ROC;

               (xvii)   To the best of our knowledge after reasonable inquiry
          and based on a certificate of the Company, the Company is not in
          violation of its Articles of Incorporation or other constituent
          documents and is not 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

          (h)  Allen & Gledhill, Republic of Singapore ("Singapore") counsel for
     ASE Test Limited ("ASE Test"), shall have furnished to you their written
     opinion dated such Time of Delivery, in form and substance satisfactory to
     you, substantially to the effect that:

               (i)    ASE Test has been duly incorporated, is validly existing
          under the laws of Singapore, has the corporate power and authority to
          own its property and to conduct its business as described in the
          Prospectus;

               (ii)   as at 31st August 2000, the 38,902,740 ordinary shares of
          US$0.25 each in the capital of ASE Test registered in the name of J&R
          Holding have been duly authorized and validly issued, are fully paid
          and non-assessable, and are not issued in violation of any preemptive
          or similar rights under (A) the laws of Singapore, (B) the Memorandum

          after due enquiry, any agreement or instrument binding upon ASE Test
          and governed by Singapore law; for the purposes of such opinion such
          counsel may assume that the term "non-assessable" in relation to the
          shares means under Singapore law that holders of such shares, having
          fully paid up all amounts due on such shares as to nominal amount and
          premium thereon, are under no further personal liability to contribute
          to the assets or liabilities of ASE Test in their capacities purely as
          holders of such shares;

               (iii)  as at 31st August 2000, the 3,600,000 ordinary shares of
          US$0.25 each in the capital of ASE Test registered in the name of ASE
          Holding Limited have been duly authorized and validly issued, are
          fully paid and non-assessable, and are not issued in violation of any
          preemptive or similar rights under (A) the laws of Singapore, (b) the

          aware, after due enquiry, any agreement or instrument binding upon ASE
          Test and governed by Singapore law; for the purposes of such opinion
          such counsel may assume that the term "non-assessable" in relation to
          the shares means under Singapore law that holders of such shares,
          having fully paid up all amounts due on such shares as to nominal
          amount and premium thereon, are under no further personal liability to
          contribute to the assets or liabilities of ASE Test in their
          capacities purely as holders of such shares;

               (iv)   As of such Time of Delivery, (a) such counsel is not

          obligations under this Agreement and the Deposit Agreement, and the
          consummation of the Exchange Offer will not contravene (a) any
          provision of applicable Singapore law or the Memorandum and Articles
          of Association of ASE Test, or (b) as far as such counsel is aware,

          or governmental proceedings in Bermuda pending to which J&R Holding or
          any of its Bermuda subsidiaries is a party or of which any property of

          if determined adversely to J&R Holding or any of its Bermuda
          subsidiaries, would individually or in the aggregate have a material
          adverse effect on the current or future consolidated financial
          position, shareholders' equity or results of operations of J&R Holding
          and its Bermuda subsidiaries; and, to the best of such counsel's

          or result in a breach of: (a) any  applicable  law, rule or regulation
          of Bermuda, (b) any order, judgment, injunction, decree, determination
          or award of any Bermuda court or any Bermuda judicial,  administrative
          or  governmental  authority  or  organization  presently in effect and
          applicable  to J&R Holding,  (c) any  provision of the  Memorandum  of

          Bermuda are required for J&R Holding to own, lease and use its
          properties and assets and to conduct its business in the manner
          described in, and contemplated by, the Prospectus;

          (j)  Counsel for the Depositary shall have furnished to you their
     written opinion, dated such Time of Delivery, in form and substance
     satisfactory to you, to the effect that:

               (i)    The Deposit Agreement has been duly authorized, executed
          and delivered by the Depositary and constitutes a valid and legally
          binding obligation of the Depositary, enforceable in accordance with
          its terms, subject as to enforcement to bankruptcy, insolvency,

               (ii)   The ADRs issued under and in accordance with the
          provisions of the Deposit Agreement to evidence ADSs will entitle the
          holders thereof to the rights specified therein and in the Deposit
          Agreement, assuming that (A) the Shares represented by the ADSs which
          are in turn evidenced by ADRs have been duly authorized and validly
          issued and are fully paid and nonassessable and that any preemptive
          rights with respect to the Shares have been validly waived or
          exercised and (B) such Shares have been duly deposited with Citibank,
          N.A., as Custodian, in each case under and in accordance with all
          applicable laws and regulations;

               (iii)  Upon issuance by the Depositary of ADRs evidencing ADSs
          against the deposit of Shares in respect thereof in accordance with
          the provisions of the Deposit Agreement, such ADRs will be duly and
          validly issued and the person in whose name the ADRs are registered
          will be entitled to the rights specified therein and in the Deposit
          Agreement; and

               (iv)   The ADS Registration Statement and any amendments thereof
          or supplements thereto, as of their respective effective dates,
          compiled as to form in all material respects with the requirements of
          the Act and the rules and regulations of the Commission thereunder;

     Subsidiary or the Significant Subsidiaries, otherwise than as set forth or
     contemplated in the Prospectus, the effect of which, in any such case
     described in clause (i) or (ii), is in the judgment of the Representatives
     so material and adverse as to make it impracticable or inadvisable to
     proceed with the public offering or the delivery of the ADSs being

     impracticable or inadvisable to proceed with the public offering or the
     delivery of the ADSs being delivered at such Time of Delivery on the terms
     and in the manner contemplated in the Prospectus or (vi) the occurrence of
     any material adverse change in the existing financial, political or
     economic conditions in the United States, the United Kingdom and the ROC or
     elsewhere which, in the judgment of the Representatives would materially
     and adversely affect the financial markets or the market for the ADSs and
     other equity securities;

     forth in subsections (a), (l) and (s) of this Section, and as to such other
     matters as you may reasonably request.

     8.  (a)  The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement, the ADR Registration Statement or the Prospectus, or any amendment 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 will reimburse each
Underwriter for any legal or other expenses reasonably incurred by such
Underwriter in connection with investigating or defending any such action or
claim as such expenses are incurred; provided, however, that the Company shall
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 an untrue statement or alleged
untrue statement or omission or alleged omission made in any Preliminary
Prospectus, the Registration Statement, the ADR Registration Statement or the
Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through Goldman Sachs (Asia) L.L.C. expressly for use therein.

     (b)  The Subsidiary will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement, the ADR Registration Statement or the Prospectus, or any amendment 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 will reimburse each
Underwriter for any legal or other expenses reasonably incurred by such
Underwriter in connection with investigating or defending any such action or
claim as such expenses are incurred; provided, however, that the Subsidiary
shall 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 an untrue statement or
alleged untrue statement or omission or alleged omission made in any Preliminary
Prospectus, the Registration Statement, the ADR Registration Statement or the
Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
any Underwriter through Goldman Sachs (Asia) L.L.C. expressly for use therein.

     (c)  Each Underwriter will indemnify and hold harmless the Company and the
Subsidiary against any losses, claims, damages or liabilities to which the
Company and the Subsidiary may become subject, under the Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement, the ADR Registration Statement or the Prospectus, or any
amendment or supplement thereto, or


                                      -35-
<PAGE>   36
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, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in any Preliminary Prospectus, the Registration
Statement, the ADR Registration Statement or the Prospectus or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through Goldman Sachs
(Asia) L.L.C. expressly for use therein; and will reimburse the Company or the
Subsidiary for any legal or other expenses reasonably incurred by the Company
and the Subsidiary in connection with investigating or defending any such action
or claim as such expenses are incurred.

     (d)  Promptly after receipt by an indemnified party under subsection (a),
(b) or (c) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against an indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (which shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the written consent
of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (i)
includes an unconditional release of the indemnified party from all liability
arising out of such action or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act, by or on behalf of
any indemnified party.

     (e)  If the indemnification provided for in this Section 8 is unavailable
to or insufficient to hold harmless an indemnified party under subsection (a),
(b) or (c) above in respect of any losses, claims, damages or liabilities (or
actions in respect thereof) referred to therein, then each indemnifying party
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Subsidiary on the one hand and the Underwriters
on the other from the offering of the ADSs. If, however, the allocation provided
by the immediately preceding sentence is not permitted by applicable law or if
the indemnified party failed to give the notice required under subsection (d)
above, then each indemnifying party shall contribute to such amount paid or
payable by such indemnified party in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of the
Company and the Subsidiary on the one hand and the Underwriters on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions in respect thereof), as well as any
other relevant equitable considerations. The relative benefits received by the
Company and the Subsidiary on the one hand (it being understood that for
purposes of this subsection (e) any benefit received by the Subsidiary shall
also be deemed to have been


                                      -36-
<PAGE>   37
received by the Company) and the Underwriters on the other shall be deemed to be
in the same proportion as the total net proceeds from the offering of the ADSs
purchased under this Agreement (before deducting expenses) received by the
Company and the Subsidiary bear to the total underwriting discounts and
commissions received by the Underwriters with respect to the ADSs purchased
under this Agreement, in each case as set forth in the table on the cover page
of the Prospectus. The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company and the Subsidiary on the one hand or the
Underwriters on the other and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company, the Subsidiary and the Underwriters agree that it would not be just
and equitable if contributions pursuant to this subsection (d) were determined
by pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to above in this subsection (d). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (e) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (d), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the ADSs underwritten by
it and distributed to the public were offered to the public exceeds the amount
of any damages which such Underwriter has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. 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. The Underwriters'
obligations in this subsection (e) to contribute are several in proportion to
their respective underwriting obligations and not joint.

     (f)  The obligations of the Company or the Subsidiary, respectively, under
this Section 8 shall be in addition to any liability which the Company or the
Subsidiary, respectively, may otherwise have and shall extend, upon the same
terms and conditions, to the respective affiliates [and agents] of each
Underwriter and to each person, if any, who controls any Underwriter within the
meaning of the Act; and the obligations of the Underwriters under this Section 8
shall be in addition to any liability which the respective Underwriters may
otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company or the Subsidiary, as the case may be, and
to each person, if any, who controls the Company or the Subsidiary, as the case
may be, within the meaning of the Act.

     9.  (a)  If any Underwriter shall default in its obligation to purchase the
ADSs which it has agreed to purchase hereunder at a Time of Delivery, you may in
your discretion arrange for you or another party or other parties to purchase
such ADSs on the terms contained herein. If within thirty-six hours after such
default by any Underwriter you do not arrange for the purchase of such ADSs,
then the Company shall be entitled to a further period of thirty-six hours
within which to procure another party or other parties satisfactory to you to
purchase such ADSs on such terms. In the event that, within the respective
prescribed periods, you notify the Company that you have so arranged for the
purchase of such ADSs, or the Company notify you that they have so arranged for
the purchase of such ADSs, you or the Company shall have the right to postpone
such Time of Delivery for a period of not more than seven days, in order to
effect whatever changes may thereby be made necessary in the Registration
Statement or the Prospectus, or in any other documents or arrangements, and the
Company agrees to file promptly any amendments to the Registration Statement or
the Prospectus which in your opinion may thereby be made necessary. The term


                                      -37-
<PAGE>   38
"Underwriter" as used in this Agreement shall include any person substituted
under this Section with like effect as if such person had originally been a
party to this Agreement with respect to such ADSs.

     (b)  If, after giving effect to any arrangements for the purchase of the
ADSs of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such ADSs which
remains unpurchased does not exceed one-eleventh of the aggregate number of all
of the ADSs to be purchased at such Time of Delivery, then the Company shall
have the right to require each non-defaulting Underwriter to purchase the number
of ADSs which such Underwriter agreed to purchase hereunder at such Time of
Delivery and, in addition, to require each non-defaulting Underwriter to
purchase its pro rata share (based on the number of ADSs which such Underwriter
agreed to purchase hereunder) of the ADSs of such defaulting Underwriter or
Underwriters for which such arrangements have not been made; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

     (c)  If, after giving effect to any arrangements for the purchase of the
ADSs of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such ADSs which
remains unpurchased exceeds one-eleventh of the aggregate number of all of the
Shares to be purchased at such Time of Delivery, or if the Company shall not
exercise the right described in subsection (b) above to require non-defaulting
Underwriters to purchase ADSs of a defaulting Underwriter or Underwriters, then
this Agreement (or, with respect to the Second Time of Delivery, the obligations
of the Underwriters to purchase and of the Subsidiary to sell the Optional ADSs)
shall thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company, except for the expenses to be borne by the Company
and the Underwriters as provided in Section 6 hereof and the indemnity and
contribution agreements in Section 8 hereof; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

     10.  The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Subsidiary and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, or the Company, or any officer or director or controlling person of
the Company, the Subsidiary or any controlling person of the Subsidiary, and
shall survive delivery of and payment for the ADSs.

     11.  If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor the Subsidiary shall be under any liability to any
Underwriter except as provided in Sections 6 and 8 hereof; but, if for any other
reason any Firm ADSs and/or, if applicable, Optional ADSs are not delivered by
or on behalf of the Company or the Subsidiary as provided herein, the Company
and the Subsidiary will reimburse the Underwriters through you for all
out-of-pocket expenses approved in writing by you, including fees and
disbursements of counsel, reasonably incurred by the Underwriters in making
preparations for the purchase, sale and delivery of the Firm ADSs and/or, if
applicable, Optional ADSs not so delivered, but the Company and the Subsidiary
shall then be under no further liability to any Underwriter in respect of the
Firm ADSs and/or, if applicable, Optional ADSs not so delivered, except as
provided in Sections 6 and 8 hereof.

     12.  In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman Sachs (Asia) L.L.C. on behalf of you as the
representatives.


                                      -38-
<PAGE>   39
     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman Sachs
(Asia) L.L.C., 68th Floor, Cheung Kong Center, 2 Queen's Road Central, Hong
Kong, Attention: Legal Department; and if to the Company or the Subsidiary shall
be delivered or sent by mail, telex or facsimile transmission to the address of
the Company set forth in the Registration Statement, Attention: Chief Financial
Officer; provided, however, that any notice to an Underwriter pursuant to
Section 8 (d) hereof shall be delivered or sent by mail, telex or facsimile
transmission to such Underwriter at its address set forth in its Underwriters'
Questionnaire or telex constituting such Questionnaire, which address will be
supplied to the Company or the Subsidiary by you upon request. Any such
statements, requests, notices or agreements shall take effect upon receipt
thereof.

     13.  This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company, the Subsidiary and, to the extent provided in
Sections 8 and 10 hereof, the officers and directors of the Company, the
Subsidiary and each person who controls the Company, the Subsidiary or any
Underwriter, and their respective heirs, executors, administrators, successors
and assigns, and no other person shall acquire or have any right under or by
virtue of this Agreement. No purchaser of any of the ADSs from any Underwriter
shall be deemed a successor or assign by reason merely of such purchase.

     14.  Each of the parties hereto irrevocably (i) agrees that any legal suit,
action or proceeding against the Company or the Subsidiary brought by any
Underwriter or by any person who controls any Underwriter arising out of or
based upon this Agreement or the transactions contemplated hereby may be
instituted in any New York court, (ii) waives, to the extent permitted by
applicable law, any objection which it may now or hereafter have to the laying
of venue of any such proceeding and (iii) submits to the [exclusive]
jurisdiction of such courts in any such suit, action or proceeding. Each of the
Company and the Subsidiary has appointed C.T. Corporation System, New York, New
York, as its authorized agent (the "Authorized Agent") upon whom process may be
served in any such action arising out of or based on this Agreement or the
transactions contemplated hereby which may be instituted in any New York Court
by any Underwriter or by any person who controls any Underwriter, expressly
consents to the jurisdiction of any such court in respect of any such action,
and waives any other requirements of or objections to personal jurisdiction with
respect thereto. Such appointment shall be irrevocable. Each of the Company and
the Subsidiary represents and warrants that the Authorized Agent has agreed to
act as such agent for service at process and agrees to take any and all action,
including the filing of any and all documents and instruments, that may be
necessary to continue such appointment in full force and effect as aforesaid.
Service of process upon the Authorized Agent and written notice of such service
to the Company and the Subsidiary, as the case may be, shall be deemed, in every
respect, effective service of process upon the Company and the Subsidiary, as
the case may be.

     15.  In respect of any judgment or order given or made for any amount due
hereunder that is expressed and paid in a currency (the "judgment currency")
other than United States dollars, the Company and the Subsidiary, as the case
may be, will, to the extent permitted by applicable law, indemnify each
Underwriter against any loss incurred by such Underwriter as a result of any
variation as between (i) the rate of exchange at which the United States dollar
amount is converted into the judgment currency for the purpose of such judgment
or order and (ii) the rate of exchange at which an Underwriter is able to
purchase United States dollars with the amount of the judgment currency actually
received by such Underwriter. The foregoing indemnity shall constitute a
separate and independent obligation of the Company and the Subsidiary and shall
continue in full force and effect notwithstanding any such judgment or order as
aforesaid. The term "rate of exchange" shall


                                      -39-
<PAGE>   40
include any premiums and costs of exchange payable in connection with the
purchase of or conversion into United States dollars.

     16.  Time shall be of the essence of this Agreement. As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     17.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK.

     18.  This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.


                                      -40-

     If the foregoing is in accordance with your understanding, please sign and
return to us counterparts hereof, and upon the acceptance hereof by you, on
behalf of each of the Underwriters, this letter and such acceptance hereof shall
constitute a binding agreement among each of the Underwriters, the Company and
the Subsidiary. It is understood that your acceptance of this letter on behalf
of each of the Underwriters is pursuant to the authority set forth in a form of
Agreement among Underwriters, the form of which shall be submitted to the

                  FORM OF ANNEX I DESCRIPTION OF COMFORT LETTER
                     FOR REGISTRATION STATEMENT ON FORM F-1


     Pursuant to Section 7(k) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

          (i)    They are independent certified public accountants with respect
     to the Company and its subsidiaries within the meaning of the Act and the
     applicable published rules and regulations thereunder;

          (ii)   In their opinion, the financial statements and any
     supplementary financial information and schedules (and, if applicable,
     financial forecasts and/or pro forma financial information) examined by
     them and included in the Prospectus or the Registration Statement comply as
     to form in all material respects with the applicable accounting
     requirements of the Act and the related published rules and regulations
     thereunder; and, if applicable, they have made a review in accordance with
     standards established by the American Institute of Certified Public
     Accountants of the unaudited consolidated interim financial statements,
     selected financial data, pro forma financial information, financial
     forecasts and/or condensed financial statements derived from audited
     financial statements of the Company for the periods specified in such
     letter, as indicated in their reports thereon, copies of which have been
     furnished to the representatives of the Underwriters (the
     "Representatives")[and are attached hereto];

          (iii)  They have made a review in accordance with standards
     established by the American Institute of Certified Public Accountants of
     the unaudited condensed consolidated statements of income, consolidated
     balance sheets and consolidated statements of cash flows included in the
     Prospectus as indicated in their reports thereon copies of which [have been
     separately furnished to the Representatives][are attached hereto]; and on
     the basis of specified procedures including inquiries of officials of the
     Company who have responsibility for financial and accounting matters
     regarding whether the unaudited condensed consolidated financial statements
     referred to in paragraph (vi)(A)(i) below comply as to form in all material
     respects with the applicable accounting requirements of the Act and the
     related published rules and regulations, nothing came to their attention
     that caused them to believe that the unaudited condensed consolidated
     financial statements do not comply as to form in all material respects with
     the applicable accounting requirements of the Act and the related published
     rules and regulations;

          (iv)   The unaudited selected financial information with respect to
     the consolidated results of operations and financial position of the
     Company for the five most recent fiscal years included in the Prospectus
     agrees with the corresponding amounts (after restatements where applicable)
     in the audited consolidated financial statements for such five fiscal years
     which were included or incorporated by reference in the Company's Annual
     Reports on Form 20-F for such fiscal years;

          (v)    They have compared the information in the Prospectus under
     selected captions with the disclosure requirements of Regulation S-K and on
     the basis of limited procedures specified in such letter nothing came to
     their attention as a result of the


                                      I-1
<PAGE>   45
     foregoing procedures that caused them to believe that this information does
     not conform in all material respects with the disclosure requirements of
     Items 8 and 11 of Form 20-F and of Regulation S-K;

          (vi)   On the basis of limited procedures, not constituting an
     examination in accordance with generally accepted auditing standards,
     consisting of a reading of the unaudited financial statements and other
     information referred to below, a reading of the latest available interim
     financial statements of the Company and its subsidiaries, inspection of the
     minute books of the Company and its subsidiaries since the date of the
     latest audited financial statements included in the Prospectus, inquiries
     of officials of the Company and its subsidiaries responsible for financial
     and accounting matters and such other inquiries and procedures as may be
     specified in such letter, nothing came to their attention that caused them
     to believe that:

               (A)  (a)  the unaudited consolidated statements of income,
          consolidated balance sheets and consolidated statements of cash flows
          included in the Prospectus do not comply as to form in all material
          respects with the applicable accounting requirements of the Act and
          the related published rules and regulations, or (ii) any material
          modifications should be made to the unaudited condensed consolidated
          statements of income, consolidated balance sheets and consolidated
          statements of cash flows included in the Prospectus for them to be in
          conformity with generally accepted accounting principles;

               (B)  any other unaudited income statement data and balance sheet
          items included in the Prospectus do not agree with the corresponding
          items in the unaudited consolidated financial statements from which
          such data and items were derived, and any such unaudited data and
          items were not determined on a basis substantially consistent with the
          basis for the corresponding amounts in the audited consolidated
          financial statements included in the Prospectus;

               (C)  the unaudited financial statements which were not included
          in the Prospectus but from which were derived any unaudited condensed
          financial statements referred to in clause (A) and any unaudited
          income statement data and balance sheet items included in the
          Prospectus and referred to in clause (B) were not determined on a
          basis substantially consistent with the basis for the audited
          consolidated financial statements included in the Prospectus;

               (D)  any unaudited pro forma consolidated condensed financial
          statements included in the Prospectus do not comply as to form in all
          material respects with the applicable accounting requirements of the
          Act and the published rules and regulations thereunder or the pro
          forma adjustments have not been properly applied to the historical
          amounts in the compilation of those statements;

               (E)  as of a specified date not more than five days prior to the
          date of such letter, there have been any changes in the consolidated
          capital stock (other than issuances of capital stock upon exercise of
          options and stock appreciation rights, upon earn-outs of performance
          shares and upon conversions of convertible securities, in each case
          which were outstanding on the date of the latest financial statements
          included in the Prospectus) or any increase in the consolidated
          long-term debt of the Company and its subsidiaries, or any decreases
          in


                                      I-2
<PAGE>   46
          consolidated net current assets or stockholders' equity or other items
          specified by the Representatives, or any increases in any items
          specified by the Representatives, in each case as compared with
          amounts shown in the latest balance sheet included in the Prospectus,
          except in each case for changes, increases or decreases which the
          Prospectus discloses have occurred or may occur or which are described
          in such letter; and

               (F)  for the period from the date of the latest financial
          statements included in the Prospectus to the specified date referred
          to in clause (E) there were any decreases in consolidated net revenues
          or operating profit or the total or per share amounts of consolidated
          net income or other items specified by the Representatives, or any
          increases in any items specified by the Representatives, in each case
          as compared with the comparable period of the preceding year and with
          any other period of corresponding length specified by the
          Representatives, except in each case for decreases or increases which
          the Prospectus discloses have occurred or may occur or which are
          described in such letter; and

          (g)  In addition to the examination referred to in their report(s)
     included in the Prospectus and the limited procedures, inspection of minute
     books, inquiries and other procedures referred to in paragraphs (iii) and
     (vi) above, they have carried out certain specified procedures, not
     constituting an examination in accordance with generally accepted auditing
     standards, with respect to certain amounts, percentages and financial
     information specified by the Representatives, which are derived from the
     general accounting records of the Company and its subsidiaries, which
     appear in the Prospectus, or in Part II of, or in exhibits and schedules
     to, the Registration Statement specified by the Representatives, and have
     compared certain of such amounts, percentages and financial information
     with the accounting records of the Company and its subsidiaries and have
     found them to be in agreement.

     Re: Advanced Semiconductor Engineering, Inc. -- Lock-Up Agreement
Ladies and Gentlemen:

     The undersigned understands that you, as representatives (the

     In consideration of the agreement by the Underwriters to offer and sell the
