OPTION AGREEMENT

OPTION AGREEMENT, dated as of December 30, 2004 between MagnaChip Semiconductor LLC, a Delaware limited liability company (the “Company”), and Jerry M. Baker (the “Grantee”), pursuant to the MagnaChip Semiconductor LLC Equity Incentive Plan (the “Plan”). Capitalized terms that are not defined herein shall have the meanings given to such terms in the Plan.

WHEREAS, the Company desires to grant options to purchase its restricted Common Units (the “Restricted Units”) to certain employees and consultants of its wholly-owned subsidiary, MagnaChip Semiconductor, Ltd. (the “MagnaChip Korea”);

WHEREAS, the Company has adopted the Plan in order to effect such grants; and

WHEREAS, the Committee has determined that it is in the interest of the Company to grant these options to the Grantee.

NOW, THEREFORE, in consideration of the premises and subject to the terms and conditions set forth herein and in the Plan, the parties hereto agree as follows:

1. Confirmation of Grant.

(a) Confirmation of Grant. The Company hereby evidences and confirms the grant to the Grantee, effective as of the date hereof (the “Grant Date”), of options to purchase from the Company the number of Restricted Units specified on the signature page hereof (the “Options”) at the exercise price of $1.00 per Restricted Unit (the “Option Price”).

(b) Options Subject to Plan. The Options granted pursuant to this Agreement are subject in all respects to the Plan, all of the terms of which are made a part of and incorporated into this Agreement. By signing this Agreement, the Grantee acknowledges that the Grantee has been provided a copy of the Plan and has had the opportunity to review such Plan.

(c) Character of Options. The Options granted hereunder are non-qualified options and not intended to be “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended.

2. Exercisability.

(a) Exercisability. The Options shall be fully-vested and immediately exerciseable on the Grant Date.

(b) Normal Expiration Date. Unless the Options earlier terminate in accordance with Section 4, the Options shall terminate on the first anniversary of the Grant Date (the “Normal Expiration Date”).

3. Method of Exercise and Payment.

All or part of the exercisable Options may be exercised by the Grantee upon (a) the Grantee’s written notice to the Company of exercise, (b) the Grantee’s payment of the Option Price in full at the time of exercise (i) in cash or cash equivalents or (ii) in accordance with such procedures or in such other form as the Committee shall from time to time determine, (c) the Grantee’s execution of a subscription agreement which shall be in substantially the form of the Restricted Unit Subscription Agreement attached hereto as Exhibit A, and (d) the Grantee’s execution of a joinder to the Securityholders’ Agreement and LLC Agreement (if the Grantee is not then a party to such agreements) in order to become a party to such agreements with respect to the Restricted Units issuable upon the exercise of such Options.

The Restricted Unit Subscription Agreement shall contain provisions providing that, upon any termination of the Grantee’s employment with MagnaChip Korea, the Restricted Units shall be subject to forfeiture and/or repurchase by the Company.

4. Termination of Employment.

Upon termination of the Grantee’s employment, the Options shall be exercisable only in accordance with the terms of the Plan. Notwithstanding anything else contained herein to the contrary, the Committee may at any time extend the post-termination exercise period of all or any portion of the Options up to and including, but not beyond, the Normal Expiration Date of such Options.

5. Tax Withholding.

Whenever Restricted Units are to be issued pursuant to the exercise of an Option or any cash payment is to be made hereunder, The Company shall have the power to withhold, or require the Grantee to remit to the Company, an amount sufficient to satisfy federal, state, and local withholding tax requirements relating to such transaction, and the Company may defer payment of cash or issuance of Restricted Units until such requirements are satisfied.

6. Nontransferability of Awards.

Unless the Committee shall permit (on such terms and conditions as it shall establish) Options to be transferred, no Options may be sold, transferred, pledged, assigned or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. Following the Grantee’s death, all rights with respect to Options that were exercisable at the time of the Grantee’s death and have not terminated may be exercised by his designated beneficiary, his estate or such transferee as permitted by the Committee.

7. Beneficiary Designation.

The Grantee may from time to time name any beneficiary or beneficiaries (who may be named contingently or successively) by whom any right under the Plan and this Agreement is to be exercised in case of his death. Each designation will revoke all prior designations by the Grantee, shall be in a form reasonably prescribed by the Committee, and will be effective only when filed by the Grantee in writing with the Committee during his lifetime. If no beneficiary is named, or if a named beneficiary does not survive the Grantee, the Successor Holder may exercise the Grantee’s rights under the Plan.

8. Requirements of Law.

The issuance of Restricted Units pursuant to the Options shall be subject to all applicable laws, rules and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. Such issuance may be delayed, if necessary, to comply with applicable laws, including the U.S. federal securities laws and any applicable state or foreign securities laws, and no Restricted Units shall be issued upon exercise of any Options granted hereunder, if such exercise would result in a violation of applicable law.

9. No Guarantee of Employment.

Nothing in this Agreement shall interfere with or limit in any way the right of the Company or any of its subsidiaries to terminate the Grantee’s employment at any time, or confer upon the Grantee any right to continue in the employ of MagnaChip Korea.

10. No Rights as Securityholder.

Except as otherwise required by law, the Grantee shall not have any rights as a securityholder with respect to any Restricted Units covered by the Options granted hereby until such time as the Restricted Units issuable upon exercise of such Options have been so issued. Notwithstanding anything else contained herein to the contrary, the exercise of any portion of the Options hereby is expressly conditioned on the Grantee executing a subscription agreement which shall be in substantially the form of the Restricted Unit Subscription Agreement attached hereto as Exhibit A.

11. Interpretation; Construction.

Any determination or interpretation by the Committee under or pursuant to this Agreement shall be final and conclusive on all persons affected hereby. Except as otherwise expressly provided in the Plan, in the event of a conflict between any term of this Agreement and the terms of the Plan, the terms of the Plan shall control.
