8.       CAPACITY PLANNING AND FORECASTING

          (A) As a condition to the execution of this Agreement, Motorola shall
provide ASE with a written forecast for the total monthly volume of the Contract
Products, itemized by package type and pin count, that Motorola plans to order
from ASE during the twelve (12) months immediately following the date hereof.
After the end of each subsequent month, Motorola shall provide ASE with an
update to the forecast (a "Twelve Month Rolling Forecast"), which is to be used
by ASE to allocate capacity for the Work. The Twelve Month Rolling Forecast
shall establish the minimum capacity of ASE to be available to Motorola during
each month of the immediately following twelve (12) month period, upon the
acceptance thereof by ASE. The absence of any notice of objection to a Twelve
Month Rolling Forecast given by ASE within seven (7) calendar days of the date
of receipt shall be deemed as acceptance by ASE. Motorola makes no
representation or warranty with respect to the accuracy of any Twelve Month
Rolling Forecast.

         (B) Using the Twelve Month Forecasts, ASE will provide sufficient
capacity for                       *                    of the Work specified
for each month. ASE will place orders for materials using such suppliers and

                                        6

<PAGE>   7
upon such lead times as Motorola and ASE shall mutually agree. If Motorola's
forecasts for any Contract Products significantly decrease, and such decrease
results, after      *     , in more than        *        of inventory of unique
materials purchased by ASE to support Motorola's requirements, and which
inventory cannot be used for any other ASE customer, then Motorola will purchase
the inventory above      *     from ASE          *      , provided
that ASE had purchased reasonable quantities of such materials based on
Motorola's forecasts. It is ASE's intention to work with its suppliers and with
Motorola to allocate certain of such risks among all parties to the extent
practicable, and it is understood by the parties that the provisions of this
Section 8(B) are subject to review by the parties concurrently with the issuance
of any new pricing Supplement pursuant to Section 16 of this Agreement.

         (C) ASE and Motorola shall negotiate in good faith on the financial
obligation of each Party with respect to, and delivery times for, any capital
equipment required by ASE to support Motorola's requirements if such equipment
is unique to Motorola's specifications and cannot be used without material
modification or expenditure by ASE to support other customers. Such negotiation
shall include good faith attempts of the Parties to find alternative uses for
such equipment. This Subsection shall not apply to capital equipment additions
within the contemplation of the Parties prior to the effective date of this
Agreement, which includes ASE's approved      *    for the Chung Li Facility and
another      *       planned to support Motorola's MAPBGA ramp-up.

         (D) ASE agrees to use commercially reasonable efforts to accommodate
mix and option changes required by Motorola's business needs.

         (E) If the Work required is either significantly more or significantly
less than that specified by the relevant twelve month forecast, Motorola shall
communicate such information to ASE as soon as such information is available.

9.       ORDER PLACEMENT AND DELIVERY

         (A) Blanket purchase orders for Contract Products shall periodically be
placed by Motorola with ASE. The sole purpose of the blanket purchase order is
to establish the price for each Contract Product, as set forth in the
Supplements to this Agreement and any new Contract Products added to this
Agreement, and to provide a purchase order number which ASE's invoices shall
reference. All preprinted terms and conditions contained in the blanket purchase
orders, including the aggregate purchase prices, are superceded by the terms and
conditions of this Agreement and the Supplements hereto. Motorola's actual
orders for the Contract Products shall also be placed with ASE periodically. The
actual orders shall provide details regarding specific Contract Products, mix,

quantities, shipping instructions and requested shipment dates. ASE agrees to
comply with the requested shipment dates unless it advises Motorola otherwise
within seven (7) calendar days following its receipt of the actual orders. ASE
shall use its commercially reasonable efforts to deliver the exact quantity of
the Contract Products ordered. ASE shall adopt Motorola's Demand Driven
Production Requirements (DDPR) system for piece part forecasting and, unless
otherwise mutually agreed, ASE shall adopt Motorola's Contract House Accounts
Payable System (CHAPS) for inventory accounting and payment.

         (B) "ON-TIME DELIVERIES" means as deliveries made no more than
*        days before or on ASE's scheduled delivery dates. Time is of the
essence in delivery. ASE shall establish a system to ensure all deliveries to be
made on time.

         (C) If      *      per cent   *    on-time deliveries are not achieved,
ASE agrees to take appropriate corrective actions, including communication of
the delivery problems to Motorola. ASE shall also take a systematic approach to
develop, evaluate and monitor adherence to established on-time delivery
requirements. ASE will notify Motorola when the on-time delivery requirement
will not be met. ASE and Motorola will in good faith negotiate the compensation
to be paid by ASE to Motorola, if any, for actual, direct damages incurred by
Motorola as a result of such late delivery. ASE agrees to implement Supplier
Managed Inventory with Motorola so that Contract Products will be provided on a
demand-pull basis.

10.      CANCELLATIONS AND SCHEDULE CHANGES

         (A) ASE may cancel a firm order   *  if it terminates this Agreement on
the basis of an uncured payment default by Motorola as provided in Subsection
30(A) hereof.

         (B) Delivery schedule changes may be made by mutual agreement. Motorola

Contract Products and delay shipment for up to thirty (30) calendar days. ASE
shall certify to Motorola with each shipment that the Contract Products
therein have successfully passed applicable testing and meet all specifications.
Acceptance testing of the Contract Products delivered to Motorola shall be
performed by Motorola within              *                of receipt.

         (B) If Motorola rejects any Contract Products, Motorola and ASE shall
confer to determine the reason for the rejection. ASE shall immediately exercise
commercially reasonable efforts to develop and implement a corrective action
plan for any errors, including manufacturing errors or defects, identified in
its systems. All properly rejected Contract Products that are confirmed by ASE
to be nonconforming may be returned to ASE for a refund at the purchase price
stated in the applicable Supplement, plus Motorola's shipping cost, or may be
retained by Motorola subject to a mutually agreed credit issued by ASE to be
applied to future orders by Motorola. Title and risk of loss or damage to return
merchandise authorization (RMA) material shall pass to ASE ExWorks (EXW)
(Incoterms 1990) Motorola's dock.

12.      SCRAP

         (A) The scrap rates for the Scrap of each type of the Contract Products
shall not exceed the corresponding average rates experienced by Motorola at the
Chung Li Facility during 1999 while Motorola owned the Facility. Motorola
represents that such average scrap rates are true and correct and have resulted

selling price for the relevant Contract Product, for Scrap in excess of the
applicable average rate. ASE shall use commercially reasonable efforts to
continually reduce Scrap rates for Contract Products.

         (B) ASE shall dispose of any Scrap in accordance with applicable laws
and Motorola's written instructions. Upon request, ASE shall ship all Scrap to
Motorola separately from any of the Contract Products or Bailed Property in

38.      APPLICABLE LAW

         The laws of the United States and, where applicable, the state of New
York, shall govern this Agreement, except for that body of law known as
conflicts of laws. The Parties expressly agree that the UN Convention for the
International Sale of Goods shall not apply.

39.      DISPUTE RESOLUTION

         (A) The Parties shall attempt to settle any claim or controversy
arising out of this Agreement through consultation and negotiation in good faith
and a spirit of mutual cooperation. If those attempts fail, the dispute shall be
mediated by a mutually acceptable mediator to be chosen by the Parties within
            *                 after written notice by one of the Parties
demanding mediation. Neither Party may unreasonably withhold its consent to the
selection of a mediator, and the Parties shall share the costs of the mediation
equally. By mutual agreement, however, the Parties may postpone mediation until
each has completed some specified but Limited discovery about the dispute. The
Parties may also agree to replace mediation with non-binding alternative dispute
resolution, such as neutral fact-finding or a mini-trial. Disputes relating to
the intellectual property of either Party shall not be subject to mediation or
alternative dispute resolution.

         (B) Any dispute which cannot be resolved through negotiation or
mediation within              *           of the initial demand by either
Party shall then be finally resolved by a court within the state of New York.
The use of alternative dispute resolution shall not be construed under the
doctrines of laches, waiver or estoppel to affect adversely the rights of either
Party. Nothing in this Subsection 39(B) shall prevent either Party from
resorting to judicial proceedings if: (i) good faith efforts to resolve the
dispute under these procedures have been unsuccessful, or (ii) interim relief
from a court is necessary to prevent serious and irreparable injury to one Party
or to others.

         (C) EXCEPT AS MAY BE OTHERWISE SPECIFICALLY PROVIDED IN THIS AGREEMENT,
IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR ANY SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES OF ANY NATURE WHATSOEVER (INCLUDING, WITHOUT LIMITATION,
LOST PROFITS) REGARDLESS OF THE LEGAL THEORY ON WHICH ANY SUCH CLAIM MAY BE
MADE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

41.      SEVERABILITY

         If any provision of this Agreement should become fully or partially
invalid or unenforceable for any reason whatsoever, or violate any applicable
law, this Agreement is to be considered divisible as to such provision and such
provision deleted from this Agreement, and the remainder of this Agreement shall

         The failure of any Party to enforce, at any time, or for any period of
time, any provision of this Agreement, to exercise any election or option
provided herein, or to require, at any time, performance of any of the
provisions hereof, shall not be construed to be a waiver of such provision, or
in any way affect the validity of this Agreement, or any part thereof, or the
right of any Party thereafter to enforce each and every such provision.

43.      INDEPENDENT CONTRACTOR

         It is agreed that ASE is an independent contractor for the performance
