       The Purchase Price shall be subject to adjustment after the Completion
       Date according to this Clause 5.1.

       (a)    As soon as practicable, but in any event no later than forty-five
              (45) days after the Completion Date, ASE shall, at its cost and
              expense, prepare and deliver to NECY a balance sheet of the
              Company as of the Completion Date (the "Final Completion Date
              Balance Sheet"), including a calculation of the proposed
              Completion Date Net Worth of the Company, together with a report
              thereon from an internationally recognized firm of independent
              certified public accountants reasonably satisfactory to NECY
              confirming the consistency of such calculation with GAAP and
              practices consistently applied.

       (b)    NECY shall have a period commencing upon delivery of the Final
              Completion Date Balance Sheet by ASE to NECY and expiring
              forty-five (45) days after such delivery date to review the Final
              Completion Date Balance Sheet. NECY and NECY's independent
              certified public accountants (the "Seller's Accountants") shall
              have full access during regular business hours and upon reasonable
              notice to all relevant books and records and employees of the

              Final Completion Date Balance Sheet in a manner not unreasonably
              interfering with the business of the Company. In the event NECY
              disputes that the Completion Date Net Worth was determined in
              accordance with GAAP and practices consistently applied with the
              Estimated Completion Date Balance Sheet, NECY shall, within
              forty-five (45) days after delivery of the Final Completion Date
              Balance Sheet, deliver a notice to ASE (the "Adjustment Dispute
              Notice"), setting forth in reasonable detail the component or
              components which are in dispute and the basis of such dispute. If
              the Parties fail to resolve any such dispute within thirty (30)
              days after receipt by ASE of the Adjustment Dispute Notice, the
              Parties shall submit the dispute to PricewaterhouseCoopers LLP or
              its Japanese affiliate (the "Reviewing Accountant") to review the
              Completion Date Net Worth set forth on the Final Completion Date
              Balance Sheet. Each Party hereby represents and warrants that
              neither the Party nor any of its Affiliates uses the Reviewing
              Accountant as its accountant or has any material relationship
              therewith. The Parties shall make available to the Reviewing
              Accountant all work papers and all other information and material
              in their possession relating to the matters in the Adjustment
              Dispute Notice. The Reviewing Accountant's authority shall be
              limited to determining whether the component or components of
              Completion Date Net Worth set forth on the Final Completion Date
              Balance Sheet which have been so disputed by NECY were

                                       9
<PAGE>

              calculated in accordance with GAAP and practices consistently
              applied with the Estimated Completion Date Balance Sheet and, if
              necessary, determining the adjustments required to such Completion
              Date Net Worth to cause it to be calculated in accordance with
              GAAP and practices consistently applied with the Estimated
              Completion Date Balance Sheet. The Reviewing Accountant shall be
              instructed by the Parties to use its best efforts to deliver to
              the Parties its determination as promptly as practicable after
              such submission of the dispute to the Reviewing Accountant. The
              Parties hereby expressly agree that the determination of the
              Reviewing Accountant shall be final and binding on the Parties
              (absent fraud or manifest bad faith by the Reviewing Accountant).
              The Completion Date Net Worth on the Final Completion Date Balance
              Sheet as determined by ASE (if not disputed), or as modified (if
              at all) by agreement of ASE and NECY or by decision of the
              Reviewing Accountant, shall be the "Final Completion Date Net
              Worth". Each Party shall bear its own expenses and the fees and
              expenses of its own representatives and experts, including its
              independent accountants, in connection with the preparation,
              review, dispute (if any) and final determination of the Final
              Completion Date Net Worth. The Parties shall share equally in the
              costs, expenses and fees of the Reviewing Accountant.

       (c)    If the Final Completion Date Net Worth varies greater than one
              million Japanese yen (JPY 1,000,000) from the Estimated Completion
              Date Net Worth, within five (5) days following the determination
              of the Final Completion Date Net Worth, the Purchase Price shall
              be adjusted yen for yen and payment shall become due as follows:
              (i) if the Final Completion Date Net Worth exceeds the Estimated
              Completion Date Net Worth, the Purchase Price shall be increased
              by the amount of such excess and the Buyer shall pay over such
              excess to NECY in accordance with Clause 5.1(d) below, or (ii) if
              the Final Completion Date Net Worth is less than the Estimated
              Completion Date Net Worth, the Purchase Price shall be decreased
              by the amount of such deficit and NECY shall pay over such deficit
              to the Buyer in accordance with Clause 5.1(d) below. If the Final
              Completion Date Net Worth varies less than one million Japanese
              yen (JPY 1,000,000) from the Estimated Completion Date Net Worth,
              no adjustment to the Purchase Price shall be made.

       (d)    The payment of any adjustment provided for in this Clause 5.1
              shall be made by wire transfer of immediately available funds to
              an account designated by the receiving party. Any such payment
              shall also include interest on the amount of such payment,
              calculated for the period between the Completion Date and the date
              of payment (both dates are inclusive) at the short term prime rate
              then offered by most Japanese city banks (toshi ginko) as
              according to the most recent financial and economic statistics
              (kinyu keizai toukei) reported by the Bank of Japan.

              required to be performed or complied with by the Seller Parties on

              have been granted, made or obtained;

       (g)    the Transaction Documents shall have been executed and delivered
              by the relevant parties thereto other than the Buyer Parties and
              shall not have been terminated;

       (h)    Prior to the consummation of the Company Split:

              (i)    NECY shall have timely delivered the proposed Incorporation

                     such delivery within two (2) weeks following its receipt
                     thereof, provided that (1) ASE's objections to such
                     deliveries shall only be asserted when ASE reasonably
                     determines (as confirmed by ASE's internationally
                     recognized outside accounting or actuarial advisors) that
                     there is non-compliance with GAAP, the applicable terms of
                     this Agreement or prevailing market assumptions, and (2)
                     ASE shall disclose the details of the objection to NECY in
                     writing upon providing the objection notice; and

              (iii)  NECY and ASE shall have agreed to a resolution of ASE's
                     objection, if any, following good faith discussions for no
                     longer than fourteen (14) days after NECY's receipt of
                     ASE's objection.

       The Parties acknowledge that notwithstanding the satisfaction of this
       condition to Completion, the Estimated Completion Date Balance Sheet,
       the PBO Liability and the Deferred Tax Assets shall be subject to final
       review and approval (and additional revisions in connection therewith)

                     3.2(d);

              (ii)   At the Completion Date, all of the Key Employees (or their

                     transfer to the Company or objected to the Transactions;
                     and

       (j)    There shall not have occurred any event, fact, circumstance, or
              action that would be reasonably likely to have a Material Adverse
              Effect.

       Ltd. shall change its corporate name to such other name which does not

       change, notify NECY thereof in writing.

9.2    Use of "ASE Japan"

       ASE agrees (on behalf of itself and its Affiliates) that neither it nor
       any of its Affiliates will bring any claim or action against the Seller
       Parties, or any of their Affiliates or agents, with regard to the use of
       "ASE Japan" as the company name of the Company, subject to the Seller
       Parties' compliance with their obligations under Clause 12.1(a) and any
       express restrictions agreed by the Parties with respect to the use of the
       "ASE Japan" name, and except for any Damages regarding the use of "ASE
       Japan" as the Company's name to the extent attributable to actions of (i)
       the Seller Parties or (ii) the Company prior to the Completion Date that
       are not authorized by the Buyer Parties.

9.3    Transfer Restriction of Shares

       During the Supplying Period:

       (a)    ASE shall hold more than two-thirds (2/3) of the voting rights of
              the issued and outstanding shares in the Buyer, and the Buyer
              shall hold more than two-thirds (2/3) of the voting rights of the

              voting rights of the issued and outstanding shares in the Company
              shall exceed fifty percent (50%).

       amount of paid-in capital of greater than three hundred million Japanese
       yen (JPY 300,000,000) in order to prevent the Company from being
       categorized as a Subcontractor (shitauke jigyousha) under the
       Subcontractors Act. In the event that Article 2, Section 4 of the
       Subcontractors Act should be amended, then ASE shall cause the Company to
       maintain an amount of paid-in capital so that the Company will not be
       categorized as a Subcontractor (shitauke jigyosha) in relation to both
       NECY and NECEL under the Subcontractors Act.

              Completion the material books, records and documents of the
              Company relating to matters recorded therein which occurred on or
              before the Completion with respect to the Business; and

       (b)    until the fifth (5th) anniversary of the Completion (or in the
              event of any claim being made by ASE under the Seller Party
              Warranties until such later time as the same is determined) NECY
              and its agents, accountants, lawyers and other professional
              advisers shall be allowed the right to inspect and, at NECY's
              expense, take copies of the books, records and documents (but in
              each case only in relation to matters recorded therein which
              occurred on or before the Completion) at all reasonable times upon
              NECY giving reasonable notice of such requirement to the Company.
              NECY's rights under this Clause may be exercised solely for
              purposes relating to the Transaction Documents or NECY's
              compliance with requirements of Governmental Authorities.

9.7    Continuation of Employees

       During the Supplying Period, ASE shall ensure that:

              package and Benefit Plan) of the Transferred Employees or other
              restructuring of the Transferred Employees will not be implemented
              without prior written consent of NECEL, not to be unreasonably
              withheld, and shall comply with applicable Laws (including
              communications with labor unions); provided however that the
              following will not require NECEL's prior consent:

              (i)    the termination of a Transferred Employee for breach of
                     applicable employment terms, wrongdoing, misconduct or
                     inadequate job performance (including failure to comply
                     with management policies or directives) in accordance with
                     applicable Laws; or

              (ii)   decisions regarding management personnel of the Company.

                                       15
<PAGE>

       (b)    In the case of Clause 9.7(a)(i), the Company shall provide NECEL
              with a copy of the applicable employee termination notice not
              later than the earlier of (i) fourteen (14) days prior to the
              intended termination date, or (ii) such other date on which a
              notice to the employee is required under applicable Law. In the
              case of Clause 9.7(a)(ii), the Company shall provide written
              notice to NECEL at least fourteen (14) days prior to the
              applicable management personnel decision.

10.    Employee Arrangements

10.1   The Seller Parties shall use their commercially reasonable efforts to
       cause the Proposed Transferred Employees to transfer to the Company in
       connection with the Transactions as contemplated by this Agreement. In
       connection therewith:

       (a)    The Parties acknowledge that certain of NECY's employees engaged
              in the Business will not be included in the Proposed Transferred
              Employees, even though such employees are entitled under Law to be
              transferred to the Company in the Company Split. NECY shall use
              its commercially reasonable efforts to obtain consents from these
              employees not to be transferred in the Company Split; and

       (b)    The Parties acknowledge that certain of the Proposed Transferred
              Employees are not employees who would transfer to the Company by
              operation of Law in the Company Split. NECY shall use its
              commercially reasonable efforts to obtain consents from these
              Proposed Transferred Employees to transfer to the Company in
              connection with the Transactions.

10.2   The Seller Parties shall use their commercially reasonable efforts to
       cause all independent contractors, contract or temporary workers, leased
       employees, consultants and similar persons who provide services with
       respect to the Business to continue to provide such services to the
       Company following the Completion on terms no less favorable to the
       Company than the terms currently in effect.

10.3   Four identified individuals currently seconded to NECY and working in the
       Business will continue as seconded employees to the Company upon
       Completion; provided that the secondment term shall not be longer than
       four (4) years following the Completion Date without ASE's prior consent.

10.4   Pre-Completion Period Bonus

       (a)    On June 18, 2004 or such other date as designated by NECY, the
              Company shall pay certain bonuses as designated by NECY to each of
              the Transferred Employees designated by NECY, which corresponds to
              the service period from October 1, 2003 to March 31, 2004
              ("Pre-Completion Period Bonus").

       (b)    Within five (5) Business Days following the Company's payment of
              the Pre-Completion Period Bonus, the Company shall notify NECY of
              the Pre-Completion Period Bonus payment, together with
              documentation which reasonably demonstrates that the Company has
              actually paid the Pre-Completion Period Bonus to the applicable
              Transferred Employees.

       (c)    Within five (5) Business Days following the Company's notification
              of payment under Clause 10.4(b), NECY shall reimburse the Company
              for its payment of the Pre-Completion Period Bonus, such
              reimbursement to be made to the bank account designated by the
              Company in writing.

                                       16

11.    Benefit Plan Arrangements

11.1   In principle, upon the completion of the Company Split, the Company shall
       succeed to and assume the Seller Benefit Plans with respect to the
       Transferred Employees for periods from and after the Company Split Date.
       For the avoidance of doubt, the treatment of Seller Benefit Plan
       Liabilities as part of the Excluded Liabilities (as provided in the
       definition of Excluded Liabilities) and the Company's indemnification
       rights under Clause 14.1(d) with respect to such Seller Benefit Plan
       Liabilities shall not be affected by this Clause and the Company's
       succession and assumption contemplated hereby.

11.2   The Seller Parties shall ensure that the Company will not at any time
       prior to Completion become subject to, or participate in, or incur any
       Liability with respect to the NEC Employee Pension Fund (NEC kigyou
       nenkin kikin).

11.3   As promptly as practicable following the date hereof, the Buyer Parties
       shall deliver a statement describing the Buyer Parties' intentions
       regarding a new health insurance plan that the Transferred Employees will
       participate in after the Completion Date.

11.4   NECY Plan Assets

       (a)    At least two (2) weeks prior to the Company Split Date, NECY may
              submit a proposal to ASE for the post-Completion transfer to the
              Company of certain investment assets covering the Company's
              obligations under the NECY Plans, to the extent such assets relate
              to the PBO Liability (such assets contemplated to be transferred
              are described herein as the "NECY Plan Assets"). Such proposal
              shall include the estimated value of the NECY Plan Assets as of
              the Completion Date, and information (including fund trustee and
              other third party confirmation) about the feasibility of
              transferring the NECY Plan Assets to the Company. NECY and ASE
              shall discuss such proposal in good faith. If NECY and ASE agree
              on the estimated value of the NECY Plan Assets as of the
              Completion Date, such agreed value shall be netted against the
              reasonably estimated aggregate projected benefit obligation to the
              Transferred Employees as of the Completion Date under the NECY
              Plans in determining the amount of the PBO Liability, in
              accordance with the definition of such term.

       (b)    If the Parties are not able to agree on the estimated value of the
              NECY Plan Assets as of the Completion Date, no such netting shall
              occur in determining the amount of the PBO Liability; provided
              that if NECY is able to achieve the transfer of such assets to the
              Company within a reasonable period of time following the
              Completion, ASE shall cause the Company to compensate NECY in the
              amount of such transferred assets promptly after such transfer.

12.    Covenants by the Seller Parties

12.1   Pre-Completion Covenants

       The Seller Parties shall observe each of the following covenants until
       the Completion Date:

       (a)    NECY shall conduct the Business, and cause the Company to conduct
              the Business after the Company Split Date, only in the ordinary
              course; and

       (b)    The applicable Seller Parties shall enter into the Transaction
              Documents with the Company at or prior to the Completion Date.

                                       17
<PAGE>

12.2   Interim Working Capital

       NECEL shall provide debt financing to the Company at an annual interest
       rate not to exceed 3-month Yen TIBOR as at 11am (Tokyo time) on the 2nd
       Business Day prior to the draw-down date plus 0.55% to finance the
       working capital requirements of the Company from the Company Split Date
       until the Completion. Repayment of such debt financing (the "Working
       Capital Loan") will be paid in full to NECEL at Completion as
       contemplated by Clause 7.4(b).

12.3   Access and Availability

       Between the date hereof and the Completion Date, the Seller Parties shall
       give ASE and its representatives reasonable access during normal business
       hours and upon reasonable notice to all the Facilities, financial data
       and other books and records of the Seller Parties, to the extent
       applicable to or in connection with the Business, the related assets and
       liabilities, the establishment of the Company, the Transaction Documents
       or compliance by ASE or its Affiliates with the requirements of Law or
       Governmental Authorities, and shall furnish ASE and its representatives
       with all such information related thereto and facilitate such compliance
       therewith, and with access to employees, representatives, independent
       contractors, consultants or similar persons, accountants, lawyers and
       other professional advisors of the Seller Parties as ASE may reasonably
       request, including actuarial and other information, assumptions, and
       materials relating to the deliveries by NECY pursuant to Clause 3.2;
       provided, however, that such access does not unreasonably disrupt the
       normal operations of NECY.

13.    Commercially Reasonable Efforts

       Each Party shall use its commercially reasonable efforts to cause the
       conditions to the other Party's Completion obligations in Article 6 to be
       satisfied as soon as practicable, including using its commercially
       reasonable efforts to obtain all material Governmental Approvals which
       are necessary for the consummation of the Transactions. Without limiting
       the foregoing, neither Party shall take any action that would reasonably
       be expected to cause any of the other Party's Completion conditions in
       Article 6 not to be satisfied as of the Completion.

14.    Indemnity

14.1   Indemnification by the Seller Parties

       The Seller Parties jointly and severally agree to pay, indemnify and hold
       harmless the Buyer Parties, the Company and their respective Affiliates,
       directors, officers, employees, agents and assigns (the "Buyer
       Indemnified Parties") from and against any and all losses, Liabilities,
       claims, damages, judgments, costs and expenses (including reasonable
       attorneys' fees) ("Damages") as a result of, or based upon or arising
       from:

       (a)    the breach or inaccuracy of any of the Seller Party Warranties
              provided herein or in the certificate of the Seller Parties
              pursuant to Clause 6.2(e);

       (b)    the facts and matters disclosed in Section 11 of the Seller
              Disclosure Schedule;

       (c)    any breach or failure to perform any of the covenants, agreements
              or obligations of the Seller Parties in this Agreement; or

       (d)    the Excluded Liabilities; provided that (i) the Seller Parties'
              indemnity obligations with respect to Warranty Liabilities that
              are part of the Excluded Liabilities shall expire upon the
              expiration of the applicable statute of limitations or effective
              term of

                                       18
<PAGE>

              the Law or Contract (as applicable) giving rise to the Warranty
              Liability, and (ii) the Seller Parties' indemnity obligations
              with respect to Environmental Liabilities that are part of the
              Excluded Liabilities shall expire on the fifth (5th) anniversary
              of the Completion Date, provided that if any claim or notice for
              indemnity hereunder with respect to Environmental Liabilities
              that are part of the Excluded Liabilities is given prior to the
              fifth (5th) anniversary of the Completion Date, then the
              liability of the Seller Parties for such claim shall continue
              indefinitely until such claim is finally resolved.

14.2   Indemnification by the Buyer Parties

       The Buyer Parties jointly and severally agree to pay, indemnify and hold
       harmless the Seller Parties and their respective Affiliates, directors,
       officers, employees, agents and assigns (the "Seller Indemnified
       Parties") from and against any and all Damages as a result of, or based
       upon or arising from:

       (a)    the breach or inaccuracy of any of the Buyer Party Warranties
              provided herein or in the certificate of the Buyer Parties
              pursuant to Clause 6.1(d);

       (b)    any breach or failure to perform any of the covenants, agreements
              or obligations of the Buyer Parties in this Agreement; or

       (c)    the use of "ASE Japan" as the Company's name, subject to the
              Seller Parties' compliance with their obligations under Clause
              12.1(a) and any express restrictions agreed by the Parties with
              respect to the use of the "ASE Japan" name, and except for any
              Damages regarding the use of "ASE Japan" as the Company's name to
              the extent attributable to actions of (i) the Seller Parties or
              (ii) the Company prior to the Completion Date that are not
              authorized by the Buyer Parties.

14.3   Effective Period

       The Liabilities of the Seller Parties under the Seller Party Warranties
       contained in Schedule 8.2 and of the Buyer Parties under the Buyer
       Party Warranties contained in Schedule 8.3 (and their respective
       indemnity obligations under this Article 14 with respect to such
       warranties) shall cease on the date which is eighteen (18) months after
       the Completion Date except that:

       (a)    if any claim or notice for indemnity hereunder with respect to any
              Seller Party Warranties or Buyer Party Warranties is given prior
              to the termination of the applicable warranties under this clause,
              then the liability of the applicable Parties for such warranties
              shall continue indefinitely until such claim is finally resolved;
              and

       (b)    the Seller Party Warranties under Clause 4(b) (Title of Shares),
              Clause 14 (Benefit Plans), Clause 17 (Environmental Matters) and
              Clause 19 (Taxes) of Schedule 8.2 shall continue through the
              expiration of the applicable statute of limitations.

14.4   Procedure for Indemnification

       A claim by the Seller Indemnified Parties to the Buyer Parties or by
       the Buyer Indemnified Parties to the Seller Parties for indemnification
       for any matter (other than an External Claim, which will be governed by
       Article 15) shall be made by written notice reasonably specifying the
       nature of the claim and the amount of Damages asserted to the extent
       known. Upon receipt of such notice, the indemnifying parties and
       indemnified parties shall negotiate in good faith for a period of up to
       sixty

                                       19
<PAGE>

       (60) days to agree on the amount of indemnifiable Damages suffered by the
       indemnified parties. If no agreement is reached within this sixty (60)
       day period, the Parties shall resolve the dispute in accordance with
       Clause 18.3 (for the avoidance of doubt, no further discussions between
       the Parties under Clause 18.3(a) shall be required as a condition to a
       Party's request for arbitration under Clause 18.3). The amount of Damages
       agreed by the Parties or the amount of Damages determined in accordance
       with Clause 18.3, as the case may be, is hereafter referred to as a
       "Claim Amount".

14.5   Limitations on Claim Amount

       (a)    The Seller Parties shall have no Liability with respect to claims
              for indemnity under Clause 14.1(a) (i) for any single claim unless
              the Damages under such claim (together with all related claims)
              exceeds one million Japanese yen (JPY 1,000,000), or (ii) unless
              the aggregate Damages under all such claims from the Completion
              Date exceed fifty million Japanese yen (JPY 50,000,000), in which
              case the Seller Parties shall be liable (subject always to the
              other provisions of this Article 14) for the entire amount of such
              Damages. The Buyer Parties shall have no Liability with respect to
              claims for indemnity under Clause 14.2(a) (i) for any single claim
              unless the Damages under such claim (together with all related
              claims) exceeds one million Japanese yen (JPY 1,000,000), or (ii)
              unless the aggregate Damages under all such claims exceed fifty
              million Japanese yen (JPY 50,000,000), in which case the Buyer
              Parties shall be liable (subject always to the other provisions of
              this Article 14) for the entire amount of such Damages.

       (b)    The aggregate indemnification obligations of the Seller Parties to
              the Buyer Indemnified Parties pursuant to Clause 14.1(a) or the
              Buyer Parties to the Seller Indemnified Parties pursuant to Clause
              14.2(a) shall not exceed the amount equal to fifty percent (50%)
              of the sum of the Purchase Price plus the Seller Loan.

14.6   Adjustments

       Any Claim Amount shall be computed net of (i) any insurance proceeds
       received by the indemnified party and (ii) indemnification received by
       the indemnified party from a third party (other than a Seller Party or
       Buyer Party, as applicable) in connection with such claim. To the
       extent that a Claim Amount gives rise to a subsequently realized Tax
       Benefit to the indemnified party, the indemnified party shall refund to
       the indemnifying party the amount of such Tax Benefit when, as and if
       realized. For purposes of this Clause 14.6, "Tax Benefit" means an
       amount by which the tax liability of the indemnified party (or group of
       corporations including the indemnified party) is reduced (including,
       without limitation, by deduction, reduction of income by virtue of
       increased tax basis or otherwise, entitlement to refund, credit or
       otherwise) plus any related interest received from the relevant taxing
       authority. Where the indemnified party has other losses, deductions,
       credits or items available to it, the Tax Benefit from any losses,
       deductions, credits or items relating to the Claim Amount shall be
       deemed to be realized proportionately with any other losses,
       deductions, credits or items. In the event that there should be a
       determination disallowing the Tax Benefit, the indemnifying party shall
       be liable to refund to the indemnified party the amount of any related
       reduction previously allowed or payments previously made to the
       indemnifying party pursuant to this Article 14.6. The amount of the
       refunded reduction or payment shall be deemed a payment under this
       Article 14 and thus shall be paid subject to any applicable reductions
       under this Article 14.

14.7   Prompt Disclosure of Breach

       Until the 18-month anniversary of the Completion Date, each Party will
       promptly notify the other Party in writing of any matter or thing of
       which it may become aware which is a material breach of or is
       inconsistent with any of the warranties contained herein in any
       material respect; provided, that any failure or delay to give such
       notification shall not affect

                                       20
<PAGE>

       the indemnification provided under this Agreement except, and only, to
       the extent the indemnifying party shall have been actually prejudiced as
       a result of such failure or delay.

15.    External Claims

15.1   Notification and Consultation

       If an indemnified party becomes aware of any actual or threatened
       claim, demand or Proceeding asserted by any Person other than a Party
       or an Affiliate of a Party in relation to any matter to which the
       indemnities provided in Article 14 relate (an "External Claim"):

       (a)    the indemnified party shall as soon as reasonably practicable
              after so becoming aware and in any event within twenty-five (25)
              Business Days notify the indemnifying party in writing of (and in
              reasonable detail regarding) the External Claim; provided, that
              any failure or delay to give such notification shall not affect
              the indemnification provided under this Agreement except, and
              only, to the extent the indemnifying party shall have been
              actually prejudiced as a result of such failure or delay; and

       (b)    subject always to the condition, and only to the extent, that the
              interests of the indemnified party are not actually or potentially
              prejudiced thereby, the indemnified party shall thereafter consult
              with the indemnifying party in respect of the External Claim and
              permit the indemnifying party and its advisers reasonable access
              to relevant employees, premises, chattels, documents and records
              (including the right to take copies at indemnifying party's
              expense of such documents and records) for the purposes of
              investigating the External Claim and enabling the indemnifying
              party to take any action permitted by this Article 15.

15.2   Defense

       (a)    The indemnifying party shall be entitled to participate in the
              defense of the External Claim and, if it so chooses, to assume and
              control the defense thereof with counsel selected by the
              indemnifying party and reasonably acceptable to the indemnified
              party (which acceptance shall not be unreasonably withheld or
              delayed); provided that following such assumption the indemnifying
              party diligently conducts the defense thereof. If the indemnifying
              party assumes such defense, the indemnified party shall have the
              right to participate in the defense thereof, and to employ counsel
              at its own expense, provided that the indemnifying party shall be
              liable for all reasonable fees and expenses of such counsel in the
              circumstances set forth in Clause 15.2(b), it being understood
              that the indemnifying party shall control such defense and shall
              be empowered to make any settlement with respect to the External
              Claim that satisfies the conditions to the indemnified party's
              consent obligation pursuant to the last sentence of Clause
              15.2(c).

       (b)    The indemnifying party shall be liable for the reasonable fees and
              expenses of legal counsel employed by the indemnified party for
              any period during which the indemnifying party has not assumed the
              defense thereof (other than the period prior to the date on which
              the indemnified party gives notice of the External Claim as
              provided above). Notwithstanding the foregoing, if (i) the
              indemnifying party and the indemnified party shall have mutually
              agreed to the retention of separate counsel for the indemnified
              party or (ii) the named parties (including any impleaded parties)
              to an External Claim include both the indemnifying party and the
              indemnified party and the indemnified party has been advised by
              legal counsel that there is material conflict of interest
              requiring or making it advisable that the indemnified party have
              separate legal counsel, the indemnifying party shall be liable for
              all reasonable fees and expenses of

                                       21
<PAGE>

              separate legal counsel for the indemnified party in connection
              with that External Claim.

       (c)    Whether or not the indemnifying party assumes the defense of an
              External Claim, the indemnified party shall not admit any
              liability with respect to, or settle, compromise or discharge,
              such External Claim without the indemnifying party's prior written
              consent (which consent shall not be unreasonably withheld or
              delayed). However, if settled with such consent, the indemnifying
              party shall indemnify the indemnified party from and against any
              loss or liability by reason of such settlement or judgment. The
              indemnifying party shall not, without the prior written consent of
              the indemnified party, effect any settlement, compromise or
              discharge of any External Claim in respect of which any
              indemnified party is or could have been a party and indemnity
              could have been sought hereunder by such indemnified party, unless
              such settlement, compromise or discharge (i) provides for full
              settlement and complete release, without any equitable award or
              relief, and (ii) by its terms (or pursuant to a binding commitment
              of the indemnifying party) obligates the indemnifying party to pay
              the full amount of the liability in connection with such External
              Claim (subject to the provisions of Clause 14.5).

16.    Confidentiality

16.1   Each Party (the "Recipient") shall maintain in confidence all
       information (whether documentary, computerized or oral) furnished by or
       on behalf of the other Party (the "Disclosing Party") or which
       otherwise comes into the possession of the Recipient as a result of
       entering into this Agreement or the Transactions to be consummated at
       or prior to the Completion (the "Confidential Information"), shall use
       such Confidential Information only for purpose of fulfilling the terms
       of this Agreement and shall not disclose any such Confidential
       Information to a third party or make any unauthorized use thereof.
       Further, the Parties hereby confirm that the information provided from
       NECEL or NECY to ASE or the Buyer or those from ASE or the Buyer to
       NECEL or NECY pursuant to the Mutual Non-disclosure Agreement shall be
       included in the Confidential Information.

16.2   Each Recipient shall treat such Confidential Information with the same
       degree of care against disclosure or unauthorized use which it affords
       to its own confidential information of a similar nature or a reasonable
       degree of care, whichever is greater. The obligation of confidential
       treatment shall not apply to any Confidential Information that:

       (a)    was or has become generally available in the public domain other
              than through unauthorized or improper disclosure by the Recipient;

       (b)    was in the Recipient's possession prior to disclosure by the
              Disclosing Party as evidenced by documentary records;

       (c)    was independently developed by the Recipient, provided that the
              person(s) developing the same did not have prior access to
              Confidential Information received from the Disclosing Party; or

       (d)    was received from a third party who had a right to disclose such
              information.

       Notwithstanding the foregoing, (1) at the Completion, the obligations
       of the Buyer Parties under the Mutual Non-disclosure Agreement and this
       Article 16 with respect to all information relating to the Business
       shall terminate; and (2) from and after the Completion, the Seller
       Parties shall, and shall cause their Affiliates to, treat all
       information related to the Business (including all information related
       to the Business and disclosed to the Seller Parties and their
       Affiliates by the Buyer Parties or held or owned by the Seller Parties
       or their

                                       22
<PAGE>

       Affiliates prior to Completion, and excluding information which (i) was
       or has become generally available in the public domain other than through
       unauthorized or improper disclosure by the Seller Parties, (ii) is
       independently developed by the Seller Parties after the Completion, (iii)
       is received from a third party who has a right to disclose such
       information after the Completion, or (iv) generally relates to NECEL's
       assembly and test business) as Confidential Information in accordance
       with this Article 16.

16.3   In furtherance, and not in limitation, of the foregoing, each Recipient
       agrees to do the following with respect to all such Confidential
       Information:

       (a)    instruct and require all of its officers, directors, employees,
              agents, representatives or independent contractors (the
              "Representatives") to maintain the confidentiality of such
              Confidential Information and not to use such Confidential
              Information except as expressly permitted herein; and

       (b)    restrict such Confidential Information to those of its
              Representatives who have a "need to know" consistent with the
              purposes for which such Confidential Information was disclosed.

16.4   In the event that a Recipient or any of its respective Representatives
       is requested pursuant to or required by the disclosure requirements of
       any Law, rule, regulation or form of any Governmental Authority or by
       oral questions, interrogatories, requests for information or documents
       by any Governmental Authority or other Person in legal proceedings,
       subpoenas, civil investigative demands or other similar processes to
       disclose any of the Confidential Information received from the
       Disclosing Party, the Recipient or the Representative who has been so
       requested or required shall provide the Disclosing Party with prompt
       written notice of any such request or requirement so that the
       Disclosing Party may object to production, seek a protective order or
       other remedy and/or waive compliance with the provisions of this
       Agreement.

16.5   Each of the Recipients and their respective Representatives, as
       applicable, shall exercise their respective commercially reasonable
       efforts to preserve the confidentiality of such Confidential
       Information, including, without limitation, by cooperating with the
       Disclosing Party to obtain an appropriate protective order or other
       reliable assurance that confidential treatment will be afforded such
       Confidential Information. If in the absence of a protective order or
       other appropriate remedy or the receipt of a waiver of the Disclosing
       Party, the Recipient or any of its Representatives is nonetheless
       legally required or compelled to disclose such Confidential
       Information, including to any tribunal or else stand liable for
       contempt or suffer other censure or significant penalty, the Recipient
       or its Representative may, without liability hereunder, disclose only
       that portion of the Confidential Information which is legally required
       to be disclosed.

17.    Termination

17.1   This Agreement may be terminated at any time prior to the Completion
       Date:

       (a)    By consent in writing of ASE and NECY.

       (b)    By ASE or NECY, effective immediately upon written notice to the
              other party, if there has been a material violation or material
              breach by the other party of any representation, warranty,
              covenant or agreement contained herein, which violation or breach
              shall not have been cured or corrected by the violating or
              breaching party within twenty (20) Business Days after receipt of
              notice thereof, describing such violation or breach in reasonable
              detail.

                                       23
<PAGE>

       (c)    By ASE or NECY, effective immediately upon written notice to the
              other party, if the Completion has not occurred by October 31,
              2004, other than through the failure of the terminating party to
              comply with its obligations hereunder.

17.2   Effect of Termination

       If this Agreement is terminated pursuant to Clause 17.1, no Party shall
       have any Liability in respect of this Agreement, except for any
       Liabilities arising from (i) any material breach of any covenant
       contained herein occurring prior to such termination, or (ii) any
       material and intentional inaccuracy in any representation or warranty
       contained herein occurring prior to such termination; provided that
       Article 14 (Indemnity), Article 16 (Confidentiality) and Article 18
       (Miscellaneous) shall remain in full force and effect following such
       termination.

18.2   Governing Law

       This Agreement shall be construed in accordance with and governed by
       the laws of Japan, without giving effect to any choice of law rule that
       would cause the application of the laws of any jurisdiction other than
       Japan to the rights and duties of the Parties.

18.3   Dispute Resolution

       (a)    In the event that a Dispute arises hereunder, the Parties shall
              engage in mutual good faith discussions to promptly resolve the
              Dispute. Such discussions shall include, at a minimum, meetings
              and good faith discussions between representatives of each Party
              over the forty-five (45) day period commencing with initial notice
              of the Dispute.

       (b)    If the Dispute has not been resolved by the end of such forty-five
              (45) day period, then senior representatives of each Party shall
              engage in meetings and good faith discussions over the succeeding
              forty-five (45) day period. During such meetings and discussions,
              such representatives shall discuss a variety of options for
              resolving the Dispute. If the Dispute has not been resolved by the
              end of such second forty-five (45) day period, such Dispute shall
              be settled by binding arbitration in accordance with this Clause.

       (c)    Each arbitration hereunder shall be administered by the Japan
              Commercial Arbitration Association in accordance with its
              Commercial Arbitration Rules then in effect by three independent
              and impartial arbitrators. Two arbitrators shall be selected by
              the respective Parties, one by the claimant(s) and one by the
              respondent(s). The third arbitrator shall be appointed by the two
              Party-appointed arbitrators or by the Japan Commercial Arbitration
              Association if such two arbitrators cannot agree. The place of the
              arbitration shall be Tokyo, Japan. The language(s) of the
              arbitration shall be English, in which all of the arbitrators
              shall be fluent.

       (d)    Each Party may demand arbitration by filing a written demand with
              the other Party within one hundred eighty (180) calendar days
              after the expiration of the second forty-five (45) day period
              described above. The arbitrators shall have the authority to grant
              any equitable and legal remedies that would be available in any
              judicial proceeding intended to resolve a Dispute, including the
              termination of this Agreement in accordance with its terms.
              Notwithstanding the foregoing, either Party shall be entitled to
              seek preliminary injunctive relief from any court of competent
              jurisdiction, pending the final decision or award of the
              arbitrators. The award rendered in an arbitration hereunder shall
              be final and non-appealable. Judgment on the award rendered may be
              entered in any court having jurisdiction thereof.

                                       25

18.4   Consequential and Other Damages

       In no event will a Party be liable under any contract, negligence,
       strict liability or other theory for any indirect, incidental,
       consequential, punitive or other special damages (including without
       limitation lost profits).

18.5   Amendment

       This Agreement may not be amended, supplemented or modified except by
       an agreement in writing signed by each of the Parties.

18.6   Remedies

       Except as expressly provided herein, all rights, powers and remedies
       provided under this Agreement or otherwise available in respect hereof
       at law or in equity shall be cumulative and not alternative, and the
       exercise or beginning of the exercise of any thereof by a Party shall
       not preclude the simultaneous or later exercise of any other such
       right, power or remedy by such Party.

18.7   Waiver

       (a)    A Party may waive compliance by another Party with any term or
              provision of this Agreement; provided, however, that such waiver
              shall not operate as a waiver of, or estoppel with respect to, any
              other or subsequent failure. No waiver shall be effective unless
              it is in writing and is signed by the Party asserted to have
              granted such waiver.

       (b)    Neither the failure nor any delay on the part of a Party to
              exercise any right, remedy, power or privilege under this
              Agreement shall operate as a waiver thereof, nor shall any single
              or partial exercise of any right, remedy, power or privilege
              preclude any other or further exercise of the same or of any other
              right, remedy, power or privilege, nor shall any waiver of any
              right, remedy, power or privilege with respect to any occurrence
              be construed as a waiver of such right, remedy, power or privilege
              with respect to any other occurrence.

18.8   Assignments Prohibited; Successors and Assigns

       No Party shall assign, or suffer or permit an assignment of, its rights
       or obligations under or its interest in this Agreement without the
       prior written consent of the other Parties. Any purported assignment or
       other disposition by a Party, except as permitted herein, shall be null
       and void. Subject to the foregoing, this Agreement shall be binding
       upon and shall inure to the benefit of the Parties and their respective
       successors and permitted assigns.

18.9   No Third-Party Beneficiaries

       Subject to the rights of the Seller Indemnified Parties and the Buyer
       Indemnified Parties under Article 14, the terms and provisions of this
       Agreement are intended solely for the benefit of each Party hereto and
       its respective successors and permitted assigns, and the Parties do not
       intend to confer third-party beneficiary rights upon any other Person.

18.10  Severability

       If any provisions of this Agreement shall be held to be illegal,
       invalid or unenforceable, the Parties agree that such provisions will
       be enforced to the maximum extent permissible so as to effect the
       intent of the Parties, and the validity, legality and enforceability of
       the remaining provisions of this Agreement shall not in any way be
       affected or impaired thereby. If

                                       26
<PAGE>

       necessary to effect the intent of the Parties, the Parties will negotiate
       in good faith to amend this Agreement to replace the unenforceable
       language with enforceable language which as closely as possible reflects
       such intent.

18.11  Interpretation

       The table of contents and any article, section, subsection, or clause
       headings contained in this Agreement are for reference purposes only
       and shall not affect in any way the meaning or interpretation of this
       Agreement. Any reference made in this Agreement to a statute or
       statutory provision shall mean such statute or statutory provision as
       it has been amended through the date as of which the particular portion
       of the Agreement is to take effect, or to any successor statute or
       statutory provision relating to the same subject as the statutory
       provision so referred to in this Agreement, and to any then applicable
       rules or regulations promulgated thereunder. Whenever the words
       "include," "includes" or "including" are used in this Agreement, they
       shall be deemed, as the context indicates, to be followed by the words
       "but (is/are) not limited to." The words "herein," "hereof,"
       "hereunder" and words of like import shall refer to this Agreement as a
       whole (including its Schedules and Exhibits), unless the context
       clearly indicates to the contrary (for example, that a particular
       section, schedule or exhibit is the intended reference). Where specific
       language is used to clarify or illustrate by example a general
       statement contained herein, such specific language shall not be deemed
       to modify, limit or restrict the construction of the general statement
       which is being clarified or illustrated.

18.12  Number of Days

       In computing the number of days for purposes of this Agreement, all
       days shall be counted, including Saturdays, Sundays and holidays;
       provided, however, that if the final day of any time period falls on a
       day that is not a Business Day, then the final day shall be deemed to
       be the next Business Day respectively.

18.13  Construction

       This Agreement has been negotiated by the Parties and their respective
       counsel and shall be fairly interpreted in accordance with its terms
       and without any strict construction in favor of or against any of the
       Parties.

18.14  Expenses of the Parties

       Each Party shall bear the expenses incurred by such Party in connection
       with the negotiation and execution of this Agreement.

18.15  Independent Contractor

       Each Party is acting as an independent contractor and not as an agent
       of the other Parties hereto, and nothing in this Agreement shall be
       construed as creating a partnership, joint venture or similar
       relationship of any kind among the Parties hereto. No Party shall hold
       itself out as having authority to create binding obligations for the
       Parties.

18.16  Language

       This Agreement is in the English language only, which language shall be
       controlling in all respects, and all versions hereof in any other
       language shall be for accommodation only and shall not be binding upon
       the Parties.

       Each Seller Party is, and upon its establishment in the Company Split and
       at Completion the Company will be, a corporation duly organized and
       validly existing under the laws of Japan. NECY has, and upon its
       establishment in the Company Split and at Completion the Company will
       have, all requisite corporate power and authority necessary to enable it
       to own, lease or otherwise hold the Business Assets and to carry on the
       Business as presently conducted.

2.     Authorization; Validity; Enforceability.

       (a)    Each Seller Party has, and upon its establishment in the Company
              Split and at Completion the Company will have, all requisite
              corporate power and authority to enter into and perform its
              obligations under each Transaction Document to which it is a
              party.

       (b)    The execution, delivery and performance by each Seller Party of
              this Agreement and each other Transaction Document to which it is
              a party has been, and at Completion the execution, delivery and
              performance by the Company of each Transaction Document to which
              it is a party will be, duly authorized by all necessary corporate
              action on the part of the applicable entity.

       (c)    This Agreement has been, and at Completion each other Transaction
              Document to which a Seller Party or the Company is a party will
              be, duly executed and delivered by the applicable entity. This
              Agreement constitutes, and at Completion each other Transaction
              Document to which a Seller Party or the Company is a party will
              constitute, the legal, valid and binding obligation of such
              entity, enforceable against such entity in accordance with its
              terms.

3.     No Conflicts.

       (a)    Conflicts. The execution and delivery by each Seller Party and the
              Company of each Transaction Document to which it is a party does
              not and will not, and the performance by each such entity of its
              obligations thereunder will not, conflict with, result in any
              violation of or default (with or without notice or lapse of time
              or both) under, give rise to a right of termination, cancellation
              or acceleration of any obligation (in each case by any third
              party) or to the loss of any benefit by any Seller Party or the
              Company under, or result in or require the creation, imposition or
              extension of any Encumbrance upon any Business Asset under (1) the
              Charter Documents of any Seller Party or the Company, (2) any
              Contract to which a Seller Party or the Company is a party or is
              otherwise bound, or to which any Business Asset is subject, or (3)
              any Law applicable to any Seller Party or the Company.

       (b)    Approvals. Except as set forth on Section 3(b) of the Seller
              Disclosure Schedule, the consummation of the Transactions will not
              require any Approval to be obtained or made by any Seller Party or
              the Company.

                            the Shares under this Agreement; (ii) outstanding
                            securities, instruments or obligations that are or
                            may become convertible into or exchangeable for any
                            of the Company's securities; or (iii) Contracts
                            under which the Company may become obligated to
                            sell, issue or otherwise dispose of or redeem,

              Encumbrances.

       (c)    Upon its establishment in the Company Split and at Completion, the

              thereof.

       Upon the consummation of the Company Split and at Completion, the Company
       will have no off-balance sheet financing or similar financing
       arrangements and no Liabilities which are required to be provided for or

       except for such Liabilities that are reflected or reserved against on the
       Final Completion Date Balance Sheet.

7.     Absence of Certain Changes.

       Since September 30, 2003, the Business has been conducted in the ordinary
       course consistent with past practices, and there has been no change,
       event or circumstance relating to the Business which, individually or in
       the aggregate, has had, or is reasonably likely to have, a Material
       Adverse Effect.

8.     Business Assets.

       (a)    The Business Assets constitute all of the assets necessary to
              permit the Company to conduct the Business after the Completion in
              a manner substantially equivalent to the manner as the Business is
              conducted as of the date hereof, in compliance with all Laws,
              Governmental Approvals and Contracts applicable to the Business.

                                       2

       (b)    NECY has, and at Completion the Company will have, good and valid
              title to (or valid leases or licenses in respect of) all the
              Business Assets, in each case free and clear of all Encumbrances
              except Permitted Encumbrances.

       (c)    All tangible Business Assets (including such assets that are
              subject to leases and similar arrangements) are in good operating
              condition and repair, ordinary wear and tear excepted, and are
              adequate for the purpose for which they are used.

9.     Facilities.

       (a)    NECY is the owner of the Takahata Factory and NEC Corporation is
              the owner of the land on which the Takahata Factory is
              constructed, in each case free and clear of all Encumbrances
              except Permitted Encumbrances. The Facilities constitute the only
              real property at which the Business is conducted.

       (b)    Each Prime Lease is the valid and binding obligation of NECY and,
              to the knowledge of NECY, of the landlord thereunder. NECY has
              performed all obligations required to be performed by NECY under
              each Prime Lease, and no event has occurred that would render NECY
              (with or without the lapse of time or the giving of notice, or
              both) in breach or default thereunder. To the knowledge of NECY,
              no event has occurred that would render the landlord under either
              Prime Lease (with or without the lapse of time or the giving of
              notice, or both) in breach or default in any respect thereunder.

       (c)    The Takahata Factory and, to NECY's knowledge, the Facility 1
              Premises and the Facility 2 Premises are in compliance with all
              applicable Laws and Governmental Approvals. All structures,
              buildings, building systems and other improvements at the Takahata
              Factory and, to NECY's knowledge, at the Facility 1 Premises and
              the Facility 2 Premises, are in working order and repair (fair
              wear and tear excepted) and are suitable for the conduct of the
              Business thereat.

10.    Material Contracts.

       (a)    All Contracts that will be transferred to the Company in the
              Company Split (i) were entered into by NECY in the ordinary course
              of the Business, (ii) contain terms and conditions that are
              commercially reasonable with respect to the Business, and (iii) do
              not provide for termination fee obligations or other potential
              Liabilities that are materially adverse to the Company. Except as
              disclosed on Section 10(a) of the Seller Disclosure Schedule, none
              of the Contracts that will be transferred to the Company in the
              Company Split (1) are materially important to the Business (singly
              or together with all related Contracts) and (2) in the event of
              termination or expiration, would be difficult for the Company to
              replace with Contracts containing terms and conditions that are
              not materially adverse in the aggregate as compared to the
              terminated or expired Contracts. Except as disclosed on Section
              10(a) of the Seller Disclosure Schedule, each Contract that will
              be transferred to the Company in the Company Split and that
              provides for payment or performance by either party thereto having
              an aggregate value (alone or with related Contracts) exceeding or
              reasonably likely to exceed ten million Japanese yen (JPY
              10,000,000) will expire in accordance with its terms or can be
              terminated by the Company without payment or penalty prior to the
              third anniversary of the Completion Date.

       (b)    Each Contract that will be transferred to the Company in the
              Company Split and that (alone or with related Contracts) is
              material to the Business (collectively, the "Material Contracts")
              is the valid and binding obligation of NECY (and

                                       3
<PAGE>

              immediately prior to the Completion, of the Company) and, to the
              knowledge of NECY, of each other party thereto. NECY has performed
              (and immediately prior to the Completion, the Company shall have
              performed) all obligations required to be performed by it under
              the Material Contracts, and no event has occurred that would
              render it (with or without the lapse of time or the giving of
              notice, or both) in breach or default thereunder. To the knowledge
              of NECY, no event has occurred that would render any other party
              to a Material Contract (with or without the lapse of time or the
              giving of notice, or both) in breach or default in any respect
              thereunder.

11.    Intellectual Property.

       To NECY's knowledge, the conduct of the Business as conducted
       immediately prior to the Completion does not infringe, constitute a
       misappropriation or use or disclose in an unauthorized manner any
       intellectual property right of any Person. NECY has not received any
       written notice or proposal for licensing or similar arrangement
       alleging any such actual or potential infringement, misappropriation or
       unauthorized use or disclosure. To NECY's knowledge, NECY has not
       received any written proposal indicating that a license under the
       intellectual property rights of any third party is necessary in order
       to conduct the Business as it is conducted immediately prior to the
       Completion.

12.    Customers and Suppliers.

       The Seller Parties have not received written notice to the effect that
       the benefits of any material relationship of NECY or its Affiliates
       with customers or suppliers with respect to the Business will not
       continue to be available to the Company after the Completion Date.

13.    Employment.

       (a)    The list of Proposed Transferred Employees shall upon delivery in
              accordance with Clause 3.2(d) correctly reflect the grade,
              salaries, wages and other compensation, participation in Seller
              Benefit Plans, dates of employment or service, and positions of
              the Proposed Transferred Employees. None of the Transferred
              Employees has been granted the right to continued employment or
              engagement by NECY, any of its Affiliates or the Company, or to
              any compensation following or in connection with termination of
              employment or engagement with NECY, any of its Affiliates or the
              Company, subject to any rights to receive such compensation
              pursuant to applicable Law.

       (b)    Neither the execution and delivery of the Transaction Documents
              nor the consummation of the Transactions contemplated thereby will
              result in or give rise to (i) any Liability of the Company to make
              any severance, retention, termination, "golden parachute" or other
              payment to any Transferred Employee, or (ii) the acceleration of
              any other rights or benefits to any Transferred Employee
              (including vesting and payments with respect to equity incentives
              and other rights under Seller Benefit Plans), in each case whether
              pursuant to a Seller Benefit Plan, Contract, Law or otherwise.

       (c)    There are no claims or Proceedings against or affecting NECY
              pending, or to NECY's knowledge, threatened by or pertaining to
              any Transferred Employee. NECY has complied with all Laws related
              to the employment or engagement of the Transferred Employees,
              including Laws related to wages, hours, leaves of absence, equal
              opportunity, occupational health and safety, workers'
              compensation, severance, employee handbooks or manuals, collective
              bargaining, unfair labor practices and the payment of social
              security and other Taxes and withholding obligations relating
              thereto.

                                       4
<PAGE>

       (d)    Except as set forth in Section 13(d) of the Seller Disclosure
              Schedule, none of NECY or its Affiliates is a party to or is
              otherwise subject to any obligations relating to any collective
              bargaining Contract with respect to the Transferred Employees.
              There is no labor strike, slowdown or stoppage with respect to the
              Transferred Employees pending or, to NECY's knowledge, threatened
              against NECY.

       (e)    NECY has no knowledge that any of the Key Employees and not more
              than an immaterial number of the Transferred Employees have
              objected to the proposed Transactions or indicated their intent to
              terminate their employment or service with NECY or the Company.

14.    Benefit Plans.

       Each Seller Benefit Plan that the Company will succeed to and assume
       upon the consummation of the Company Split as described in Clause 11.1
       complies by its terms and in operation with the requirements provided
       by applicable Laws, except for matters that, individually or in the
       aggregate, would not have a Material Adverse Effect. Such Seller
       Benefit Plans contain terms that in the aggregate are materially
       consistent with customary and reasonable Benefit Plan practices in
       Japan.

15.    Compliance with Laws.

       The Seller Parties are and have been in compliance with all Laws that
       are applicable to the Business or the Business Assets, and no event has
       occurred, and no condition or circumstance exists, that might (with or
       without notice or lapse of time) constitute, or result directly or
       indirectly in, a default under, a material breach or violation of, or a
       material failure to comply with, any such Law. The Seller Parties have
       not received any notice from any Person regarding any actual, alleged
       or potential material violation of any Law applicable to the Business
       or the Business Assets.

16.    Governmental Approvals.

       The Seller Parties and their applicable Affiliates have obtained and
       are in compliance with all Governmental Approvals that are necessary in
       connection with the Business and the Business Assets, and all such
       Governmental Approvals are in full force and effect. Each such
       Governmental Approval will remain in full force and effect in favor of
       the Company upon consummation of the Company Split and upon Completion
       without notice to or approval by any Person, without additional payment
       and without any modification of rights and privileges thereunder,
       except for post-Completion notice filings or Approvals that will be
       made or obtained as a matter of routine and the failure to make any
       such filings or obtain any such Approvals will not have a Material
       Adverse Effect. There is no pending or, to NECY's knowledge, threatened
       Proceeding with respect to the suspension, termination, revocation,
       cancellation, limitation or impairment of any such Governmental
       Approval. No fines or penalties are due and payable in respect of any
       such Governmental Approval or any violation thereof.

17.    Environmental Matters.

       To the knowledge of NECY:

       (a)    The Business has been and is being conducted in compliance with
              applicable Environmental Laws, including with respect to the
              storage, release or disposal of Hazardous Materials.

                                       5

       (b)    The Seller Parties and their Affiliates have timely filed all
              material reports, obtained all material Approvals and generated

              required under any applicable Environmental Laws relating to the
              Business and their respective properties relating thereto.

       (c)    None of the Seller Parties or their Affiliates has received any
              notice from any Governmental Authority advising it that it is or
              may be responsible for any Environmental Liabilities relating to
              the Business.

18.    Proceedings and Orders.

       There is no Proceeding pending or, to the knowledge of NECY, threatened
       against or affecting the Business, any Business Assets, or any Seller
       Party or their respective Affiliates with respect thereto. No insurance
       company has asserted in writing that any such Proceeding is not covered
       by the applicable policy related thereto.

19.    Taxes.

       (a)    Each Tax Return required to be filed by any Seller Party relating
              in whole or in part to the Business ("Business Tax Returns"), to
              the extent required by applicable Law to be filed before the date
              hereof, has been filed, and each filed Business Tax Return is
              true, correct and complete. All Taxes shown to be payable on such
              Business Tax Returns or on subsequent assessments with respect
              thereto have been paid in full on a timely basis, and no other
              Taxes are payable relating in whole or in part to the Business,
              whether or not shown on such Business Tax Returns, for any period
              ending prior to or including the Completion Date. No Affiliate of
              the Seller Parties has been required to file Tax Returns relating
              to the Business.

       (b)    NECY has delivered or made available to ASE correct and complete
              copies of all Business Tax Returns filed by the Seller Parties or
              their Affiliates for all periods ending on or after March 31,
              1999, and copies of all Tax examination reports and notices of
              deficiency or assessment with respect to any Business Tax Returns
              received by any Seller Party or its Affiliates after March 31,
              1999.

       (c)    (i) No Seller Party or any of its Affiliates has (and upon the
              consummation of the Company Split, the Company will not have) any
              Liability for Taxes relating to the Business by Contract with any
              other Person (including any tax sharing or tax indemnity
              agreement); and (ii) there are no Encumbrances for Taxes on the

              (7) years prior to the date hereof has been audited or is
              currently the subject of audit or any Tax-related Proceeding by
              any Governmental Authority and, to NECY's knowledge, no such audit
              or Proceeding is threatened. None of the Seller Parties or their
              Affiliates has waived any statute of limitations in respect of any
              Tax related to the Business, which waiver remains in effect.

       (e)    No Seller Party or its Affiliates is a party to or the subject of
              any closing agreement, private letter ruling, technical advice
              memoranda or advance pricing agreement in respect of any Tax
