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 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,

<PAGE>

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.

      to legality of securities being registered.

5.2   Undertaking re Status of Favorable Determination Letter Covering Amkor

      Amkor has received a favorable determination letter from the Internal
      Revenue Service (the "IRS") concerning the qualification of the 401K Plan
      under Section 401(a) and related provisions of the Internal Revenue Code
      of 1986, as amended. Amkor will submit any future material amendments to
      the 401K Plan to the IRS with a request for a favorable determination that
      the 401K Plan, as amended, continues to so qualify.

23.1  Consent of PricewaterhouseCoopers LLP.

23.2  Consent of Sycip Gorres Velayo & Co., a member practice of Ernst & Young
      Global

23.3  Consent of Sycip Gorres Velayo & Co., a member firm of Arthur Andersen (2)

23.4  Consent of Samil Accounting Corporation

23.5  Consent of Wilson Sonsini Goodrich & Rosati, P.C. (contained in Exhibit

24.1  Power of Attorney (see signature page)

(1)   Incorporated by reference to the Company's Registration Statement on Form
      S-8 filed October 29, 2002 (File No. 333-100814).

(2)   The financial statements of Amkor Technology Philippines (P1/P2), Inc. and
      Amkor Technology Philippines (P3/P4), Inc., consolidated subsidiaries of
      the Registrant, for each of the two years in the period ended December 31,
      2001, have been audited by the independent public accountants Sycip Gorres
      Velayo & Co., a member firm of Arthur Andersen, (referred to herein as
      Arthur Andersen). However, the Registrant has been unable to obtain the
      written consent of Arthur Andersen with respect to the incorporation by
      reference of such financial statements in this Registrant's Registration
      Statement on Form S-8. Therefore, the Registrant has dispensed with the
      requirement to file the written consent of Arthur Andersen in reliance
      upon Rule 437a of the Securities Act of 1933, as amended. As a result, you
      may not be able to recover damages from Arthur Andersen under Section 11
      of the Securities Act of 1933, as amended, for any untrue statements of
      material fact or any omissions to state a material fact, if any, contained
      in the financial statements of the registrant for the aforementioned
      financial statements which are incorporated by reference in this
      Registration Statement.

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 or the 401K Plan'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.

23.5  Consent of Wilson Sonsini Goodrich & Rosati, P.C. (contained in Exhibit

24.1  Power of Attorney (see signature page)

(1)   Incorporated by reference to the Company's Registration Statement on Form
      S-8 filed October 29, 2002 (File No. 333-100814).

(2)   The financial statements of Amkor Technology Philippines (P1/P2), Inc. and
      Amkor Technology Philippines (P3/P4), Inc., consolidated subsidiaries of
      the Registrant, for each of the two years in the period ended December 31,
      2001, have been audited by the independent public accountants Sycip Gorres
      Velayo & Co., a member firm of Arthur Andersen, (referred to herein as
      Arthur Andersen). However, the Registrant has been unable to obtain the
      written consent of Arthur Andersen with respect to the incorporation by
      reference of such financial statements in this Registrant's Registration
      Statement on Form S-8. Therefore, the Registrant has dispensed with the
      requirement to file the written consent of Arthur Andersen in reliance
      upon Rule 437a of the Securities Act of 1933, as amended. As a result, you
      may not be able to recover damages from Arthur Andersen under Section 11
      of the Securities Act of 1933, as amended, for any untrue statements of
      material fact or any omissions to state a material fact, if any, contained
      in the financial statements of the registrant for the aforementioned
      financial statements which are incorporated by reference in this
      Registration Statement.
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 or the 401K Plan'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.

      Revenue Service (the "IRS") concerning the qualification of the 401K Plan
      under Section 401(a) and related provisions of the Internal Revenue Code

23.5  Consent of Wilson Sonsini Goodrich & Rosati, P.C. (contained in Exhibit
      5.1).

24.1  Power of Attorney (see signature page).

(1)   Incorporated by reference to the Company's Registration Statement on Form
      S-8 filed October 29, 2002 (File No. 333-100814).

(2)   The financial statements of Amkor Technology Philippines (P1/P2), Inc. and
      Amkor Technology Philippines (P3/P4), Inc., consolidated subsidiaries of
      the Registrant, for each of the two years in the period ended December 31,
      2001, have been audited by the independent public accountants Sycip Gorres
      Velayo & Co., a member firm of Arthur Andersen, (referred to herein as
      Arthur Andersen). However, the Registrant has been unable to obtain the
      written consent of Arthur Andersen with respect to the incorporation by
      reference of such financial statements in this Registrant's Registration
      Statement on Form S-8. Therefore, the Registrant has dispensed with the
      requirement to file the written consent of Arthur Andersen in reliance
      upon Rule 437a of the Securities Act of 1933, as amended. As a result, you
      may not be able to recover damages from Arthur Andersen under Section 11
      of the Securities Act of 1933, as amended, for any untrue statements of
      material fact or any omissions to state a material fact, if any, contained
      in the financial statements of the registrant for the aforementioned
      financial statements which are incorporated by reference in this
      Registration Statement.
