        1.     Purposes of the Plan. The purposes of this 1998 Director Option
Plan are to attract and retain the best available personnel for service as
Outside Directors (as defined herein) of the Company, to provide additional
incentive to the Outside Directors of the Company to serve as Directors, and to
encourage their continued service on the Board.


               All options granted hereunder shall be nonstatutory stock

                      (iii)  In the absence of an established market for the

sold under the Plan is 300,000 Shares of Common Stock (the "Pool"). The Shares
may be authorized, but unissued, or reacquired Common Stock.

               If an Option expires or becomes unexercisable without having been
exercised in full, the unpurchased Shares which were subject thereto shall
become available for future grant or sale under the Plan (unless the Plan has
terminated). Shares that have actually been issued under the Plan shall not be
returned to the Plan and shall not become available for future distribution
under the Plan.

        4.     Administration and Grants of Options under the Plan.

made strictly in accordance with the following provisions:



                                       -2-

<PAGE>   3

                      (i)    No person shall have any discretion to select which
Outside Directors shall be granted Options or to determine the number of Shares
to be covered by Options granted to Outside Directors.

                      (ii)   Each Outside Director shall be automatically
granted an Option to purchase 15,000 Shares (the "First Option") on the date on
which the later of the following events occurs: (A) the effective date of this
Plan, as determined in accordance with Section 6 hereof, or (B) the date on
which such person first becomes an Outside Director, whether through election by
the stockholders of the Company or appointment by the Board to fill a vacancy;
provided, however, that an Inside Director who ceases to be an Inside Director
but who remains a Director shall not receive a First Option.

                      (iii)  Each Outside Director shall be automatically
granted an Option to purchase 5,000 Shares on each date on which such person is
re-elected by the stockholders of the Company as an Outside Director; provided
that, as of such date, he or she shall have served on the Board for at least the
preceding six (6) months.

                      (iv)   Notwithstanding the provisions of subsections (ii)
and (iii) hereof, any exercise of an Option granted before the Company has
obtained stockholder approval of the Plan in accordance with Section 16 hereof
shall be conditioned upon obtaining such stockholder approval of the Plan in
accordance with Section 16 hereof.

                      (v)    The terms of each Option granted hereunder shall be
as follows:

                             (A)    the term of the Option shall be ten (10)
years.

                             (B)    the Option shall be exercisable only while
the Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.


                             (C)    the exercise price per Share shall be 100%
of the Fair Market Value per Share on the date of grant of the Option. For
purposes of Options granted at the time of the effectiveness of this Plan
pursuant to Section 6 hereof the Fair Market Value shall be the initial price
to the Underwriters as set forth in the final prospectus included within the
registration statement on Form S-1 filed with the Securities and Exchange
Commission for the initial public offering of the Company's Common Stock (the
"Registration Statement").


                             (D)    subject to Section 10 hereof, the Option
shall become exercisable as to one-third (1/3) of the Shares subject to the
Option on each anniversary of its date of grant, provided that the Optionee
continues to serve as a Director on such dates.

                      (vi)   In the event that any Option granted under the Plan
would cause the number of Shares subject to outstanding Options plus the number
of Shares previously purchased under Options to exceed the Pool, then the
remaining Shares available for Option grant shall be granted under Options to
the Outside Directors on a pro rata basis. No further grants shall be made until
such time, if any, as additional Shares become available for grant under the
Plan through action of the Board or the stockholders to increase the number of
Shares which may be issued under the Plan or through cancellation or expiration
of Options previously granted hereunder.



                                       -3-

<PAGE>   4

        5.     Eligibility. Options may be granted only to Outside Directors.
All Options shall be automatically granted in accordance with the terms set
forth in Section 4 hereof.

               The Plan shall not confer upon any Optionee any right with
respect to continuation of service as a Director or nomination to serve as a
Director, nor shall it interfere in any way with any rights which the Director
or the Company may have to terminate the Director's relationship with the
Company at any time.


        6.     Term of Plan. The Plan shall become effective on the date on
which the Securities and Exchange Commission declares the Company's Registration
Statement effective. It shall continue in effect for a term of ten (10) years
unless sooner terminated under Section 11 of the Plan.


        7.     Form of Consideration. The consideration to be paid for the
Shares to be issued upon exercise of an Option, including the method of payment,
shall consist of (i) cash, (ii) check, (iii) other shares which (x) in the case
of Shares acquired upon exercise of an Option, have been owned by the Optionee
for more than six (6) months on the date of surrender, and (y) have a Fair
Market Value on the date of surrender equal to the aggregate exercise price of
the Shares as to which said Option shall be exercised, (iv) consideration
received by the Company under a cashless exercise program implemented by the
Company in connection with the Plan, or (v) any combination of the foregoing
methods of payment.

        8.     Exercise of Option.

               (a)    Procedure for Exercise; Rights as a Stockholder. Any
Option granted hereunder shall be exercisable at such times as are set forth in
Section 4 hereof; provided, however, that no Options shall be exercisable until
stockholder approval of the Plan in accordance with Section 16 hereof has been
obtained.

               An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may consist of any consideration and method of payment
allowable under Section 7 of the Plan. Until the issuance (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company) of the stock certificate evidencing such Shares, no right
to vote or receive dividends or any other rights as a stockholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
A share certificate for the number of Shares so acquired shall be issued to the
Optionee as soon as practicable after exercise of the Option. No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date the stock certificate is issued, except as provided in Section 10 of
the Plan.



                                       -4-

<PAGE>   5

               Exercise of an Option in any manner shall result in a decrease in
the number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

               (b)    Termination of Continuous Status as a Director. Subject to
Section 10 hereof, in the event an Optionee's status as a Director terminates
(other than upon the Optionee's death or total and permanent disability (as
defined in Section 22(e)(3) of the Code)), the Optionee may exercise his or her
Option, but only within three (3) months following the date of such termination,
and only to the extent that the Optionee was entitled to exercise it on the date
of such termination (but in no event later than the expiration of its ten (10)
year term). To the extent that the Optionee was not entitled to exercise an
Option on the date of such termination, and to the extent that the Optionee does
not exercise such Option (to the extent otherwise so entitled) within the time
specified herein, the Option shall terminate.

               (c)    Disability of Optionee. In the event Optionee's status as
a Director terminates as a result of total and permanent disability (as defined
in Section 22(e)(3) of the Code), the Optionee may exercise his or her Option,
but only within twelve (12) months following the date of such termination, and
only to the extent that the Optionee was entitled to exercise it on the date of
such termination (but in no event later than the expiration of its ten (10) year
term). To the extent that the Optionee was not entitled to exercise an Option on
the date of termination, or if he or she does not exercise such Option (to the
extent otherwise so entitled) within the time specified herein, the Option shall
terminate.

               (d)    Death of Optionee. In the event of an Optionee's death,
the Optionee's estate or a person who acquired the right to exercise the Option
by bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee was
entitled to exercise it on the date of death (but in no event later than the
expiration of its ten (10) year term). To the extent that the Optionee was not
entitled to exercise an Option on the date of death, and to the extent that the
Optionee's estate or a person who acquired the right to exercise such Option
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.

        9.     Non-Transferability of Options. The Option may not be sold,
pledged, assigned, hypothecated, transferred, or disposed of in any manner other
than by will or by the laws of descent or distribution and may be exercised,
during the lifetime of the Optionee, only by the Optionee.

        10.    Adjustments Upon Changes in Capitalization, Dissolution, Merger
or Asset Sale.

               (a)    Changes in Capitalization. Subject to any required action
by the stockholders of the Company, the number of Shares covered by each
outstanding Option, the number of Shares which have been authorized for issuance
under the Plan but as to which no Options have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option, as well
as the price per Share covered by each such outstanding Option, and the number
of Shares issuable



                                       -5-

<PAGE>   6

pursuant to the automatic grant provisions of Section 4 hereof shall be
proportionately adjusted for any increase or decrease in the number of issued
Shares resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued Shares effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of Shares
subject to an Option.

               (b)    Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it shall terminate immediately prior to the
consummation of such proposed action.

               (c)    Merger or Asset Sale. In the event of a merger of the
Company with or into another corporation or the sale of substantially all of the
assets of the Company, outstanding Options may be assumed or equivalent options
may be substituted by the successor corporation or a Parent or Subsidiary
thereof (the "Successor Corporation"). If an Option is assumed or substituted
for, the Option or equivalent option shall continue to be exercisable as
provided in Section 4 hereof for so long as the Optionee serves as a Director or
a director of the Successor Corporation. Following such assumption or
substitution, if the Optionee's status as a Director or director of the
Successor Corporation, as applicable, is terminated other than upon a voluntary
resignation by the Optionee, the Option or option shall become fully
exercisable, including as to Shares for which it would not otherwise be
exercisable. Thereafter, the Option or option shall remain exercisable in
accordance with Sections 8(b) through (d) above.

        If the Successor Corporation does not assume an outstanding Option or
substitute for it an equivalent option, the Option shall become fully vested and
exercisable, including as to Shares for which it would not otherwise be
exercisable. In such event the Board shall notify the Optionee that the Option
shall be fully exercisable for a period of thirty (30) days from the date of
such notice, and upon the expiration of such period the Option shall terminate.

         For the purposes of this Section 10(c), an Option shall be considered
assumed if, following the merger or sale of assets, the Option confers the right
to purchase or receive, for each Share of Optioned Stock subject to the Option
immediately prior to the merger or sale of assets, the consideration (whether
stock, cash, or other securities or property) received in the merger or sale of
assets by holders of Common Stock for each Share held on the effective date of
the transaction (and if holders were offered a choice of consideration, the type
of consideration chosen by the holders of a majority of the outstanding Shares).
If such consideration received in the merger or sale of assets is not solely
common stock of the successor corporation or its Parent, the Administrator may,
with the consent of the successor corporation, provide for the consideration to
be received upon the exercise of the Option, for each Share of Optioned Stock
subject to the Option, to be solely common stock of



                                       -6-

<PAGE>   7
the successor corporation or its Parent equal in fair market value to the per
share consideration received by holders of Common Stock in the merger or sale of
assets.

        11.    Amendment and Termination of the Plan.

               (a)    Amendment and Termination. The Board may at any time
amend, alter, suspend, or discontinue the Plan, but no amendment, alteration,
suspension, or discontinuation shall be made which would impair the rights of
any Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with any applicable
law, regulation or stock exchange rule, the Company shall obtain stockholder
approval of any Plan amendment in such a manner and to such a degree as
required.

               (b)    Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated.

        12.    Time of Granting Options. The date of grant of an Option shall,
for all purposes, be the date determined in accordance with Section 4 hereof.

        13.    Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, state securities laws, and the requirements of any stock exchange
upon which the Shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

               As a condition to the exercise of an Option, the Company may
require the person exercising such Option to represent and warrant at the time
of any such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares, if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

               Inability of the Company to obtain authority from any regulatory
body having jurisdiction, which authority is deemed by the Company's counsel to
be necessary to the lawful issuance and sale of any Shares hereunder, shall
relieve the Company of any liability in respect of the failure to issue or sell
such Shares as to which such requisite authority shall not have been obtained.

        14.    Reservation of Shares. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.



                                       -7-

<PAGE>   8

        15.    Option Agreement. Options shall be evidenced by written option
agreements in such form as the Board shall approve.

        16.    Stockholder Approval. The Plan shall be subject to approval by
the stockholders of the Company within twelve (12) months after the date the
Plan is adopted. Such stockholder approval shall be obtained in the degree and
manner required under applicable state and federal law and any stock exchange
rules.

                             AMKOR TECHNOLOGY, INC.

                            DIRECTOR OPTION AGREEMENT


        Amkor Technology, Inc., a Delaware corporation (the "Company"), has
granted to ______________________________________ (the "Optionee"), an option to
purchase a total of [__________________ (_________)] shares of the Company's
Common Stock (the "Optioned Stock"), at the price determined as provided herein,
and in all respects subject to the terms, definitions and provisions of the
Company's 1998 Director Option Plan (the "Plan") adopted by the Company which is
incorporated herein by reference. The terms defined in the Plan shall have the
same defined meanings herein.

        1.     Nature of the Option. This Option is a nonstatutory option and is
not intended to qualify for any special tax benefits to the Optionee.

        2.     Exercise Price. The exercise price is $_______ for each share of
Common Stock.

        3.     Exercise of Option. This Option shall be exercisable during its
term in accordance with the provisions of Section 8 of the Plan as follows:

               (i)    Right to Exercise.

                      (a)    This Option shall become exercisable in
installments cumulatively with respect to one-third (1/3) of the Optioned Stock
one year after the date of grant, and as to an additional one-third (1/3) of
the Optioned Stock on each anniversary of the date of grant, so that one hundred
percent (100%) of the Optioned Stock shall be exercisable three years after the
date of grant; provided, however, that in no event shall any Option be
exercisable prior to the date the stockholders of the Company approve the Plan.

                      (b)    This Option may not be exercised for a fraction of
a share.

                      (c)    In the event of Optionee's death, disability or
other termination of service as a Director, the exercisability of the Option is
governed by Section 8 of the Plan.

               (ii)   Method of Exercise. This Option shall be exercisable by
written notice which shall state the election to exercise the Option and the
number of Shares in respect of which the Option is being exercised. Such written
notice, in the form attached hereto as Exhibit A, shall be signed by the
Optionee and shall be delivered in person or by certified mail to the Secretary
of the Company. The written notice shall be accompanied by payment of the
exercise price.

        4.     Method of Payment. Payment of the exercise price shall be by any
of the following, or a combination thereof, at the election of the Optionee:



<PAGE>   10

               (i)    cash;

               (ii)   check; or

               (iii)  surrender of other shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (y) have a Fair Market Value
on the date of surrender equal to the aggregate exercise price of the Shares as
to which said Option shall be exercised; or

               (iv)   delivery of a properly executed exercise notice together
with such other documentation as the Company and the broker, if applicable,
shall require to effect an exercise of the Option and delivery to the Company of
the sale or loan proceeds required to pay the exercise price.

        5.     Restrictions on Exercise. This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulations, or if such issuance
would not comply with the requirements of any stock exchange upon which the
Shares may then be listed. As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

        6.     Non-Transferability of Option. This Option may not be transferred
in any manner otherwise than by will or by the laws of descent or distribution
and may be exercised during the lifetime of Optionee only by the Optionee. The
terms of this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of the Optionee.

        7.     Term of Option. This Option may not be exercised more than ten
(10) years from the date of grant of this Option, and may be exercised during
such period only in accordance with the Plan and the terms of this Option.

        8.     Taxation Upon Exercise of Option. Optionee understands that, upon
exercise of this Option, he or she will recognize income for tax purposes in an
amount equal to the excess of the then Fair Market Value of the Shares purchased
over the exercise price paid for such Shares. Since the Optionee is subject to
Section 16(b) of the Securities Exchange Act of 1934, as amended, under certain
limited circumstances the measurement and timing of such income (and the
commencement of any capital gain holding period) may be deferred, and the
Optionee is advised to contact a tax advisor concerning the application of
Section 83 in general and the availability a Section 83(b) election in
particular in connection with the exercise of the Option. Upon a resale of such
Shares by the Optionee, any difference between the sale price and the Fair
Market Value of the Shares on the



                                       -2-

<PAGE>   11



date of exercise of the Option, to the extent not included in income as
described above, will be treated as capital gain or loss.
