ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

      As permitted by Section 145 of the Delaware General Corporation Law (the
"DGCL"), Amkor's Certificate of Incorporation provides that each person who is
or was or who had agreed


                                      II-2
<PAGE>   3
to become a director or officer of Amkor or who had agreed at the request of
Amkor's Board of Directors or an officer of Amkor to serve as an employee or
agent of Amkor or as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, shall be
indemnified by Amkor to the full extent permitted by the DGCL or any other
applicable laws. Such Certificate of Incorporation also provides that no
amendment or repeal of such Certificate shall apply to or have any effect on the
right to indemnification permitted or authorized thereunder for or with respect
to claims asserted before or after such amendment or repeal arising from acts or
omissions occurring in whole or in part before the effective date of such
amendment or repeal.

     Amkor's Bylaws provide that Amkor shall indemnify to the full extent
authorized by law any person made or threatened to be made a party to an action
or a proceeding, whether criminal, civil, administrative or investigative, by
reason of the fact that he or she was or is a director, officer or employee of
Amkor or any predecessor of Amkor or serves or served any other enterprise as a
director, officer or employee at the request of Amkor or any predecessor of
Amkor.

     Amkor has entered into indemnification agreements with its directors and
certain of its officers.

     Amkor maintains insurance on behalf of any person who is a director or
officer against any loss arising from any claim asserted against such person and
expense incurred by such person in any such capacity, subject to certain
exclusions.

ITEM 9. UNDERTAKINGS

      (a) Rule 415 Offering

            The undersigned registrant hereby undertakes:

            (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

            (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

      (b) Filings incorporating subsequent Exchange Act documents by reference

      The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

      (c) Request for acceleration of effective date or filing of registration
statement on Form S-8

      Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions described in Item 6 above, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
