Anam Semiconductor, Inc.
Seoul, Korea
Attention:  Mr. K.H. Kim

      RE:   COMMITMENT TO PURCHASE ANAM SEMICONDUCTOR, INC. COMMON SHARES

Dear Sirs:

We are writing this letter in regard to making a potential equity investment in
Anam Semiconductor, Inc. ("Anam") pursuant to the terms of its workout program
with Cho Hung Bank and the other creditor banks. Along with this request, Anam
has provided to us a document captioned the "7th Meeting of the Council of
Creditor Financial Institutions", dated February 23, 1999 (see copy of "Workout
Plan" attached hereto as Exhibit A).

It is our understanding that this Workout Plan provides the essential terms of
agreement between Anam and its creditor banks for the restructuring of Anam's
financial obligations to the banks and includes or reflects the elements of
Anam's Self-Rescue Plan. Based on our review of the Workout Plan and on the
request made to us by you, Amkor hereby issues this Letter of Commitment to make
such an equity investment upon the conditions set forth in this Letter and under
the Workout Plan.

Amkor is committed to making an equity investment in Anam of up to one hundred
and fifty million U.S. dollars ($150,000,000) over a four year period. Such
investment shall begin in 1999 in the amount of forty-one million U.S. dollars
(US $41,000,000), and shall continue annually thereafter in tranches of
forty-one million U.S. dollars ($41,000,000) (2000), forty-one million U.S.
dollars ($41,000,000) (2001) and twenty-seven million U.S. dollars ($27,000,000)
(2002). Each tranche of the Anam shares shall be purchased at a per share price
equal to 5,000 won (par value) (after giving effect to the capital reduction
described in the Workout Plan), provided that if any of the creditor banks makes
any of its required debt to equity conversions under the Workout Plan at a lower
price, Amkor shall have the benefit of such lower price for its corresponding
tranche of Anam common stock to be purchased pursuant to this commitment and the
Share Subscription Agreement referred to below.

The purchase of each tranche pursuant to the above commitment shall be dependent
upon the fulfillment of the following conditions to Amkor's reasonable
satisfaction:

<PAGE>   2

      1) Amkor and Anam shall have entered into a Share Subscription Agreement
         incorporating the terms herein prior to Amkor's initial equity
         investment;

      2) The Creditor Banks shall make their required debt to equity conversions
         under the Workout Plan including the conversions to convertible bonds
         and non-interest bearing debt simultaneously with Amkor's corresponding
         tranche of equity investment; and

      3) The terms and conditions of the Workout Plan set forth in Exhibit A
         hereto continue to be in full force and effect.

Anam and the creditor banks also understand that the aforementioned equity
investment shall occur only if Amkor and Anam shall have consummated the sale of
the K-4 facility in accordance with the terms of the Asset Purchase Agreement
dated December 30, 1998 (and any amendments thereto). Further, Anam covenants
that it will assure that the Supply Agreements between Amkor and Anam for the
provision of packaging and test services and wafer foundry services remain in
full force and effect. If Anam fails to perform this covenant, Amkor reserves
the right in its sole discretion not to make any remaining equity investment. In
the event any tranche of investment by Amkor would, in the opinion of Amkor's
independent public accountants, cause Amkor to consolidate the results of Anam
in Amkor's US GAAP financial statements, Amkor and Anam will restructure the
tranche (and/or prior tranches) in a manner that would not require Amkor to
consolidate such results.

Please indicate your agreement with this Letter of Commitment by signing where
indicated below and returning this Letter of Commitment to us.

Your prompt attention and response to this letter would be greatly appreciated.

Very truly yours,

AMKOR TECHNOLOGY,
Inc.
