                       1998 EMPLOYEE STOCK PURCHASE PLAN
                       ---------------------------------


     I.   PURPOSE OF THE PLAN

          This Employee Stock Purchase Plan is intended to promote the interests
of ISE Labs, Inc. by providing eligible employees with the opportunity to
acquire a proprietary interest in the Corporation through participation in a
payroll-deduction based employee stock purchase plan designed to qualify under
Section 423 of the Code.

          Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

     II.  ADMINISTRATION OF THE PLAN

          The Plan Administrator shall have full authority to interpret and
construe any provision of the Plan and to adopt such rules and regulations for
administering the Plan as it may deem necessary in order to comply with the
requirements of Code Section 423.  Decisions of the Plan Administrator shall be
final and binding on all parties having an interest in the Plan.

     III. STOCK SUBJECT TO PLAN

          A.   The stock purchasable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares of Common
Stock purchased on the open market.  The number of shares of Common Stock
initially authorized to be issued under the Plan is Six Hundred Thousand
(600,000) shares.  In addition, the number of shares of Common Stock reserved
for issuance under the Plan will automatically be increased on the first trading
day of each calendar year, beginning in calendar year 1999, by an amount equal
to the lessor of three percent (3%) of the total number of shares of Common
Stock outstanding on the last trading day of the preceding calendar year or four
hundred thousand (1,000,000) shares.

          B.   Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and class of securities issuable under
the Plan, (ii) the maximum number and class of securities purchasable per
Participant on any one Purchase Date and (iii) the number and class of
securities and the price per share in effect under each outstanding purchase
right in order to prevent the dilution or enlargement of benefits thereunder.

 
  IV.     OFFERING PERIODS

          A. Shares of Common Stock shall be offered for purchase under the Plan
through a series of successive offering periods until such time as (i) the
maximum number of shares of Common Stock available for issuance under the Plan
shall have been purchased or (ii) the Plan shall have been sooner terminated.

          B. Each offering period shall be of such duration (not to exceed
twenty-four (24) months) as determined by the Plan Administrator prior to the
start date of such offering period. However, the initial offering period shall
commence at the Effective Time and terminate on the last business day in July
2000. The next offering period shall commence on the first business day in
August 2000, and subsequent offering periods shall commence as designated by the
Plan Administrator.

          C.  Each offering period shall be comprised of a series of one or more
successive Purchase Intervals.  Purchase Intervals shall run from the first
business day in February each year to the last business day in July of the same
year and from the first business day in August each year to the last business
day in January of the following year.  However, the first Purchase Interval in
effect under the initial offering period shall commence at the Effective Time
and terminate on the last business day in January 1999.

          D. Should the Fair Market Value per share of Common Stock on any
Purchase Date within an offering period be less than the Fair Market Value per
share of Common Stock on the start date of that offering period, then that
offering period shall automatically terminate immediately after the purchase of
shares of Common Stock on such Purchase Date, and a new offering period shall
commence on the next business day following such Purchase Date. The new offering
period shall have a duration of twenty (24) months, unless a shorter duration is
established by the Plan Administrator within five (5) business days following
the start date of that offering period.

  V.      ELIGIBILITY

          A. Each individual who is an Eligible Employee on the start date of
any offering period under the Plan may enter that offering period on such start
date or on any subsequent Semi-Annual Entry Date within that offering period,
provided he or she remains an Eligible Employee.

          B. Each individual who first becomes an Eligible Employee after the
start date of an offering period may enter that offering period on any
subsequent Semi-Annual Entry Date within that offering period on which he or she
is an Eligible Employee.

          C. The date an individual enters an offering period shall be
designated his or her Entry Date for purposes of that offering period.

                                       2.

 
          D.  To participate in the Plan for a particular offering period, the
Eligible Employee must complete the enrollment forms prescribed by the Plan
Administrator (including a stock purchase agreement and a payroll deduction
authorization) and file such forms with the Plan Administrator (or its
designate) on or before his or her scheduled Entry Date.

     VI.  PAYROLL DEDUCTIONS

          A. The payroll deduction authorized by the Participant for purposes of
acquiring shares of Common Stock during an offering period may be any multiple
of one percent (1%) of the Base Salary paid to the Participant during each
Purchase Interval within that offering period, up to a maximum of ten percent
(10%). The deduction rate so authorized shall continue in effect throughout the
offering period, except to the extent such rate is changed in accordance with
the following guidelines:

               (i)  The Participant may, at any time during the offering period,
     reduce his or her rate of payroll deduction to become effective as soon as
     possible after filing the appropriate form with the Plan Administrator.
     The Participant may not, however, effect more than one (1) such reduction
     per Purchase Interval.

               (ii) The Participant may, prior to the commencement of any new
     Purchase Interval within the offering period, increase the rate of his or
     her payroll deduction by filing the appropriate form with the Plan
     Administrator.  The new rate (which may not exceed the ten percent (10%)
     maximum) shall become effective on the start date of the first Purchase
     Interval following the filing of such form.

          B.   Payroll deductions shall begin on the first pay day following the
Participant's Entry Date into the offering period and shall (unless sooner
terminated by the Participant) continue through the pay day ending with or
immediately prior to the last day of that offering period.  The amounts so
collected shall be credited to the Participant's book account under the Plan,
but no interest shall be paid on the balance from time to time outstanding in
such account.  The amounts collected from the Participant shall not be required
to be held in any segregated account or trust fund and may be commingled with
the general assets of the Corporation and used for general corporate purposes.

          C.   Payroll deductions shall automatically cease upon the termination
of the Participant's purchase right in accordance with the provisions of the
Plan.

          D.   The Participant's acquisition of Common Stock under the Plan on
any Purchase Date shall neither limit nor require the Participant's acquisition
of Common Stock on any subsequent Purchase Date, whether within the same or a
different offering period.

                                       3.

 
    VII.  PURCHASE RIGHTS

          A.   GRANT OF PURCHASE RIGHT.  A Participant shall be granted a
               -----------------------                                   
separate purchase right for each offering period in which he or she
participates.  The purchase right shall be granted on the Participant's Entry
Date into the offering period and shall provide the Participant with the right
to purchase shares of Common Stock, in a series of successive installments over
the remainder of such offering period, upon the terms set forth below.  The
Participant shall execute a stock purchase agreement embodying such terms and
such other provisions (not inconsistent with the Plan) as the Plan Administrator
may deem advisable.

          Under no circumstances shall purchase rights be granted under the Plan
to any Eligible Employee if such individual would, immediately after the grant,
own (within the meaning of Code Section 424(d)) or hold outstanding options or
other rights to purchase, stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Corporation
or any Corporate Affiliate.

          B.   EXERCISE OF THE PURCHASE RIGHT.  Each purchase right shall be
               ------------------------------                               
automatically exercised in installments on each successive Purchase Date within
the offering period, and shares of Common Stock shall accordingly be purchased
on behalf of each Participant (other than Participants whose payroll deductions
have previously been refunded pursuant to the Termination of Purchase Right
provisions below) on each such Purchase Date.  The purchase shall be effected by
applying the Participant's payroll deductions for the Purchase Interval ending
on such Purchase Date to the purchase of whole shares of Common Stock at the
purchase price in effect for the Participant for that Purchase Date.

          C.   PURCHASE PRICE.  The purchase price per share at which Common
               --------------                                               
Stock will be purchased on the Participant's behalf on each Purchase Date within
the offering period shall be equal to eighty-five percent (85%) of the lower of
                                                                       -----   
(i) the Fair Market Value per share of Common Stock on the Participant's Entry
Date into that offering period or (ii) the Fair Market Value per share of Common
Stock on that Purchase Date.

          D.   NUMBER OF PURCHASABLE SHARES.  The number of shares of Common
               ----------------------------                                 
Stock purchasable by a Participant on each Purchase Date during the offering
period shall be the number of whole shares obtained by dividing the amount
collected from the Participant through payroll deductions during the Purchase
Interval ending with that Purchase Date by the purchase price in effect for the
Participant for that Purchase Date.  However, the maximum number of shares of
Common Stock purchasable per Participant on any one Purchase Date shall not
exceed One Thousand Five Hundred (1,500) shares, subject to periodic adjustments
in the event of certain changes in the Corporation's capitalization. In
addition, the maximum aggregate number of shares of Common Stock purchasable by
all Participants on any one Purchase Date shall not exceed One Hundred Fifty
Thousand (150,000) shares, subject to periodic adjustments in the event of
certain changes in the Corporation's capitalization.

                                       4.

 
          E.  EXCESS PAYROLL DEDUCTIONS.  Any payroll deductions not applied to
              -------------------------                                        
the  purchase of shares of Common Stock on any Purchase Date because they are
not sufficient to purchase a whole share of Common Stock shall be held for the
purchase of Common Stock on the next Purchase Date.  However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable on the Purchase Date
shall be promptly refunded.

          F.   TERMINATION OF PURCHASE RIGHT.  The following provisions shall
               -----------------------------                                 
govern the termination of outstanding purchase rights:

               (i)   A Participant may, at any time prior to the next scheduled
     Purchase Date in the offering period, terminate his or her outstanding
     purchase right by filing the appropriate form with the Plan Administrator
     (or its designate), and no further payroll deductions shall be collected
     from the Participant with respect to the terminated purchase right.  Any
     payroll deductions collected during the Purchase Interval in which such
     termination occurs shall, at the Participant's election, be immediately
     refunded or held for the purchase of shares on the next Purchase Date.  If
     no such election is made at the time such purchase right is terminated,
     then the payroll deductions collected with respect to the terminated right
     shall be refunded as soon as possible.

               (ii)  The termination of such purchase right shall be
     irrevocable, and the Participant may not subsequently rejoin the offering
     period for which the terminated purchase right was granted. In order to
     resume participation in any subsequent offering period, such individual
     must re-enroll in the Plan (by making a timely filing of the prescribed
     enrollment forms) on or before his or her scheduled Entry Date into that
     offering period.

               (iii) Should the Participant cease to remain an Eligible
     Employee for any reason (including death, disability or change in status)
     while his or her purchase right remains outstanding, then that purchase
     right shall immediately terminate, and all of the Participant's payroll
     deductions for the Purchase Interval in which the purchase right so
     terminates shall be immediately refunded.  However, should the Participant
     cease to remain in active service by reason of an approved unpaid leave of
     absence, then the Participant shall have the right, exercisable up until
     the last business day of the Purchase Interval in which such leave
     commences, to (a) withdraw all the payroll deductions collected to date on
     his or her behalf for that Purchase Interval or (b) have such funds held
     for the purchase of shares on his or her behalf on the next scheduled
     Purchase Date.  In no event, however, shall any further payroll deductions
     be collected on the Participant's behalf during such leave.  Upon the
     Participant's return to active service within (i) ninety (90) days
     following the commencement of such leave or, if longer, the period during
     which such Participant's right to reemployment with the Corporation is
     guaranteed by either statute or contract, his or her payroll

                                       5.

 
     deductions under the Plan shall automatically resume at the rate in effect
     at the time the leave began, unless the Participant withdraws from the Plan
     prior to his or her return.  If the Participant's leave of absence, whether
     paid or unpaid, (i)

          G.   CORPORATE TRANSACTION.  Each outstanding purchase right shall
               ---------------------                                        
automatically be exercised, immediately prior to the effective date of any
Corporate Transaction, by applying the payroll deductions of each Participant
for the Purchase Interval in which such Corporate Transaction occurs to the
purchase of whole shares of Common Stock at a purchase price per share equal to
eighty-five percent (85%) of the lower of (i) the Fair Market Value per share of
                                 -----                                          
Common Stock on the Participant's Entry Date into the offering period in which
such Corporate Transaction occurs or (ii) the Fair Market Value per share of
Common Stock immediately prior to the effective date of such Corporate
Transaction.  However, the applicable limitation on the number of shares of
Common Stock purchasable per Participant and in the aggregate shall continue to
apply to any such purchase.

          The Corporation shall use its best efforts to provide at least ten
(10)-days prior written notice of the occurrence of any Corporate Transaction,
and Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Corporate Transaction.

          H.   PRORATION OF PURCHASE RIGHTS.  Should the total number of shares
               ----------------------------                                    
of Common Stock to be purchased pursuant to outstanding purchase rights on any
particular date exceed the number of shares then available for issuance under
the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

          I.   ASSIGNABILITY.  The purchase right shall be exercisable only by
               -------------                                                  
the Participant and shall not be assignable or transferable by the Participant.

          J.   STOCKHOLDER RIGHTS.  A Participant shall have no stockholder
               ------------------                                          
rights with respect to the shares subject to his or her outstanding purchase
right until the shares are purchased on the Participant's behalf in accordance
with the provisions of the Plan and the Participant has become a holder of
record of the purchased shares.

  VIII.   ACCRUAL LIMITATIONS

          A.   No Participant shall be entitled to accrue rights to acquire
Common Stock pursuant to any purchase right outstanding under this Plan if and
to the extent such accrual, when aggregated with (i) rights to purchase Common
Stock accrued under any other purchase right granted under this Plan and (ii)
similar rights accrued under other employee stock purchase plans (within the
meaning of Code Section 423) of the Corporation or any Corporate Affiliate,
would otherwise permit such Participant to purchase more than Twenty-Five
Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair

                                       6.

 
Market Value per share on the date or dates such rights are granted) for each
calendar year such rights are at any time outstanding.

          B.   For purposes of applying such accrual limitations to the purchase
rights granted under the Plan, the following provisions shall be in effect:

               (i)  The right to acquire Common Stock under each outstanding
     purchase right shall accrue in a series of installments on each successive
     Purchase Date during the offering period on which such right remains
     outstanding.

               (ii) No right to acquire Common Stock under any outstanding
     purchase right shall accrue to the extent the Participant has already
     accrued in the same calendar year the right to acquire Common Stock under
     one (1) or more other purchase rights at a rate equal to Twenty-Five
     Thousand Dollars ($25,000) worth of Common Stock (determined on the basis
     of the Fair Market Value per share on the date or dates of grant) for each
     calendar year such rights were at any time outstanding.

          C.   If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular Purchase Interval, then the payroll
deductions which the Participant made during that Purchase Interval with respect
to such purchase right shall be promptly refunded.

          D.   In the event there is any conflict between the provisions of this
Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

     IX.  EFFECTIVE DATE AND TERM OF THE PLAN

          A.   The Plan was adopted by the Board on April 2, 1998 and shall

under the Plan shall be exercised, and no shares of Common Stock shall be issued

the Securities and Exchange Commission), all applicable listing requirements of
any stock exchange (or the Nasdaq National Market, if applicable) on which the
Common Stock is listed for trading and all other applicable requirements
established by law or regulation.  In the event such stockholder approval is not
obtained, or such compliance is not effected, within twelve (12) months after
the date on which the Plan is adopted by the Board, the Plan shall terminate and
have no further force or effect, and all sums collected from Participants during
the initial offering period hereunder shall be refunded.

                                       7.

 
          B.  Unless sooner terminated by the Board, the Plan shall terminate
upon the earliest of (i) the last business day in July 2008, (ii) the date on
         --------                                                            
which all shares available for issuance under the Plan shall have been sold
pursuant to purchase rights exercised under the Plan or (iii) the date on which
all purchase rights are exercised in connection with a Corporate Transaction.
No further purchase rights shall be granted or exercised, and no further payroll
deductions shall be collected, under the Plan following such termination.

     X.   AMENDMENT OF THE PLAN

          The Board may alter, amend, suspend or discontinue the Plan at any
time to become effective immediately following the close of any Purchase
Interval.  However, the Board may not, without the approval of the Corporation's
stockholders, (i) increase the number of shares of Common Stock issuable under
the Plan or the maximum number of shares purchasable per Participant on any one
Purchase Date, except for permissible adjustments in the event of certain
changes in the Corporation's capitalization, (ii) alter the purchase price
formula so as to reduce the purchase price payable for the shares of Common
Stock purchasable under the Plan or (iii) modify eligibility requirements for
participation in the Plan.

     XI.  GENERAL PROVISIONS

          A.   All costs and expenses incurred in the administration of the Plan
shall be paid by the Corporation; however, each Plan Participant shall bear all
costs and expenses incurred by such individual in the sale or other disposition
of any shares purchased under the Plan.

          B.   Nothing in the Plan shall confer upon the Participant any right
to continue in the employ of the Corporation or any Corporate Affiliate for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Corporation (or any Corporate Affiliate employing such person)
or of the Participant, which rights are hereby expressly reserved by each, to
terminate such person's employment  at any time for any reason, with or without
cause.

          C.   The provisions of the Plan shall be governed by the laws of the
State of California without resort to that State's conflict-of-laws rules.

                                       8.
