                 INFORMATION REQUIRED IN REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE

        Amkor Technology, Inc. (the "Company" or "Registrant") hereby
incorporates by reference in this registration statement the following
documents:

        (a) The Registrant's Annual Report on Form 10-K for the fiscal year
ended December 31, 1998, as amended, filed pursuant to Section 13(a) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"); (Note with
respect to dissolution of Chong Un & Company: The Company had an investment in
Anam Semiconductor, Inc. ("ASI") as of December 31, 1997 and for the years ended
December 31, 1996 and 1997. The Company sold its investment in ASI on February
16, 1998. ASI had a consolidated subsidiary, Anam Engineering and Construction
Co., Ltd., that was audited by Chong Un & Company ("Chong Un"). A copy of the
Chong Un 1997 audit report is included in the Registrant's Annual Report on Form
10-K for the fiscal year ended December 31, 1998. The Company has been advised
that Chong Un has been dissolved and has ceased to perform accounting and
auditing services. Chong Un has not been and will not be available to perform
any subsequent review procedures with respect to its report. Further, as a
result of its status, Chong Un has not consented to the incorporation by
reference of its report into this registration statement. The Company has been
advised that the terms of Chong Un's dissolution require the preservation of its
reserves in escrow for claims of damages for the next three years and there is
no provision to distribute the firm's liquidation assets among its members. The
Company understands that judgments, if any, awarded in the US or Korea to ATI
investors rendered against Chong Un may be considered as a claim of damages
provided that the claim is appropriate under Korean law. The discussion
regarding certain effects of the Chong Un dissolution as set forth in this
registration statement is not meant and should not be construed in any way as
legal advice to any party and any potential purchaser of the Company's
securities should consult with his or her own counsel with respect to the effect
of the Chong Un dissolution on a potential purchase of the Company's securities
or otherwise.)

        (b) The Registrant's Quarterly Report on Form 10-Q for the fiscal
quarter ended March 31, 1999, filed pursuant to Section 13(a) of the Exchange
Act.

        (c) The Registrant's Quarterly Report on Form 10-Q for the fiscal
quarter ended June 30, 1999, filed pursuant to Section 13(a) of the Exchange
Act.

        (d) The Registrant's Current Report on Form 8-K, filed on August 6,
1999 pursuant to Section 13(a) of the Exchange Act.

        (e) The description of the Registrant's Common Stock contained in the
Registrant's Registration Statement on Form 8-A filed under the Exchange Act on
October 22, 1997, including any amendment or report filed for the purpose of
updating such description.

        (f) All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment to this registration statement indicating that all
securities offered hereby have been sold or deregistering all securities then
remaining unsold, shall be deemed to be incorporated by reference in this
registration statement and to be a part hereof from the date of filing of such
documents.

Directors or an officer of the Registrant to serve as an employee or agent of
the Registrant or as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, shall be

omissions occurring in whole or in part before the effective date of such

        The Registrant's Bylaws provide that the Registrant 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 the Registrant or any predecessor of the Registrant or

request of the Registrant or any predecessor of the Registrant.

        The Registrant has entered into indemnification agreements with its

ITEM 9.  UNDERTAKINGS

        (a)     Rule 415 Offering

                The undersigned registrant hereby undertakes:



                                      II-3
<PAGE>   4

                (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.

                 INFORMATION REQUIRED IN REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE

        Amkor Technology, Inc. (the "Company" or "Registrant") hereby
incorporates by reference in this registration statement the following
documents:

        (a) The Registrant's Annual Report on Form 10-K for the fiscal year
ended December 31, 1998, as amended, filed pursuant to Section 13(a) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"); (Note with
respect to dissolution of Chong Un & Company: The Company had an investment in
Anam Semiconductor, Inc. ("ASI") as of December 31, 1997 and for the years ended
December 31, 1996 and 1997. The Company sold its investment in ASI on February
16, 1998. ASI had a consolidated subsidiary, Anam Engineering and Construction
Co., Ltd., that was audited by Chong Un & Company ("Chong Un"). A copy of the
Chong Un 1997 audit report is included in the Registrant's Annual Report on Form
10-K for the fiscal year ended December 31, 1998. The Company has been advised
that Chong Un has been dissolved and has ceased to perform accounting and
auditing services. Chong Un has not been and will not be available to perform
any subsequent review procedures with respect to its report. Further, as a
result of its status, Chong Un has not consented to the incorporation by
reference of its report into this registration statement. The Company has been
advised that the terms of Chong Un's dissolution require the preservation of its
reserves in escrow for claims of damages for the next three years and there is
no provision to distribute the firm's liquidation assets among its members. The
Company understands that judgments, if any, awarded in the US or Korea to ATI
investors rendered against Chong Un may be considered as a claim of damages
provided that the claim is appropriate under Korean law. The discussion
regarding certain effects of the Chong Un dissolution as set forth in this
registration statement is not meant and should not be construed in any way as
legal advice to any party and any potential purchaser of the Company's
securities should consult with his or her own counsel with respect to the effect
of the Chong Un dissolution on a potential purchase of the Company's securities
or otherwise.)

        (b) The Registrant's Quarterly Report on Form 10-Q for the fiscal
quarter ended March 31, 1999, filed pursuant to Section 13(a) of the Exchange
Act.

        (c) The Registrant's Quarterly Report on Form 10-Q for the fiscal
quarter ended June 30, 1999, filed pursuant to Section 13(a) of the Exchange
Act.

        (d) The Registrant's Current Report on Form 8-K, filed on August 6,
1999 pursuant to Section 13(a) of the Exchange Act.

        (e) The description of the Registrant's Common Stock contained in the
Registrant's Registration Statement on Form 8-A filed under the Exchange Act on
October 22, 1997, including any amendment or report filed for the purpose of
updating such description.

        (f) All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment to this registration statement indicating that all
securities offered hereby have been sold or deregistering all securities then
remaining unsold, shall be deemed to be incorporated by reference in this
registration statement and to be a part hereof from the date of filing of such
documents.

Directors or an officer of the Registrant to serve as an employee or agent of
the Registrant or as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, shall be
indemnified by the Registrant 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.

        The Registrant's Bylaws provide that the Registrant 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 the Registrant or any predecessor of the Registrant or
serves or served any other enterprise as a director, officer or employee at the
request of the Registrant or any predecessor of the Registrant.

ITEM 9.  UNDERTAKINGS

        (a)     Rule 415 Offering

                The undersigned registrant hereby undertakes:

                                      II-3
4

                (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.
