OPTION AGREEMENT

THIS OPTION AGREEMENT is executed by and between MagnaChip Semiconductor LLC, a Delaware limited liability company (the “Company”), and Margaret Sakai (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 Common Units (the “Common Units”) to certain employees of its wholly-owned subsidiary, MagnaChip Semiconductor, Ltd. (“MagnaChip Korea”);

-1-

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

WHEREAS, the Grantee is an employee as contemplated by the Plan, and 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:

(a) Confirmation of Grant. The Company hereby evidences and confirms the grant to the Grantee of options to purchase from the Company the number of Common Units (the “Options”) at the exercise price per Common Unit (the “Option Price”) as follows:

The grant of Options to the Grantee is effective as of November 1, 2006 (the “Grant Date”), which is the later of (i) the start date of the Grantee’s employment at the Company or a subsidiary thereof, or (ii) the date on which the Options are awarded to the Grantee as set forth in the Plan. The “Vesting Commencement Date” of the Options for purposes of Section 2(a) below is November 1, 2006.

-2-

(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. In the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail.

(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.

(a) Vesting Provisions. An installment of 25% of the Common Units subject to the Options shall become vested and exercisable on the first anniversary of the Vesting Commencement Date and 6.25% of the Common Units subject to the Options shall become vested and exercisable at the end of each three month period thereafter on the same day of the month as the Vesting Commencement Date (or, if earlier, the last day of such month), so that the Options shall become fully vested and exercisable on the fourth anniversary of the Vesting Commencement Date; subject to the Grantee’s continuous employment with MagnaChip Korea from the Grant Date to each such vesting date.

(b) Normal Expiration Date. Unless the Options earlier terminate in accordance with Section 4, the Options shall terminate on the tenth anniversary of the Grant Date (the “Normal Expiration Date”). Once Options have become vested and exerciseable pursuant to this Section 2, such Options may be exercised, subject to the provisions hereof, at any time and from time to time until the Normal Expiration Date.

-3-

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 (on such Exercise Notice as provided by the Company, a form of which is attached hereto as Exhibit A), (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 and (c) the Grantee’s execution of a joinder to the LLC Agreement (if the Grantee is not then a party to such agreement) in order to become a party to such agreement with respect to the Common Units issuable upon the exercise of such Options.

(a) 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.

(b) Upon any termination of the Grantee’s employment prior to a Public Offering, the Company shall have the right to purchase all or any of the Common Units acquired by the Grantee upon exercise of any of the Options (whether acquired before or after such termination) for a cash payment equal to the Fair Market Value of such Common Units on the date of repurchase, provided that if the Grantee’s employment is terminated for Cause, then the cash payment shall be equal to the lower of the Fair Market Value and the Option Price of the Common Units so purchased. The Company’s repurchase right under this provision shall terminate ninety days after the termination of the Grantee’s employment.

-4-

Whenever Common 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 national, federal, state, and local withholding tax requirements relating to such transaction, and the Company may defer payment of cash or issuance of Common Units until such requirements are satisfied.

Unless the Committee shall permit (on such terms and conditions as it shall establish) Options and/or Common Units acquired by the Grantee upon exercise of any of the Options to be transferred, no Options or Common Units acquired by the Grantee upon exercise of any of the Options may be sold, transferred, pledged, assigned or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution; provided that the Grantee may transfer Options and/or Common Units acquired by the Grantee upon exercise of any of the Options to an immediate family member or family trust, which such family member or family trust shall not be permitted to further transfer such Options or Common Units other than back to the Grantee; further provided that the restrictions on the transfer of Common Units acquired by the Grantee upon exercise of any of the Options shall lapse on the 181st day after a Public Offering. 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.

-5-

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.

The issuance of Common 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 Common Units shall be issued upon exercise of any Options granted hereunder, if such exercise would result in a violation of applicable law.

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.

-6-

Except as otherwise required by law, the Grantee shall not have any rights as a securityholder with respect to any Common Units covered by the Options granted hereby until such time as the Common Units issuable upon exercise of such Options have been so issued.

(i) None of the Options nor any Common Units that may be acquired by the Grantee upon exercise of any of the Options (together, the “Securities”) have been registered under the United States Securities Act of 1933, as amended (the “Securities Act”), and, unless so registered, may not be offered or sold in the United States or, directly or indirectly, to U.S. Persons (as defined in subsection (c) below), except in accordance with the provisions of Regulation S of the Securities Act (“Regulation S”), pursuant to an effective registration statement under the Securities Act, or pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act;

(ii) Grantee will only offer, transfer or sell the Securities in accordance with the provisions of Regulation S, pursuant to an effective registration statement under the Securities Act, or pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act;

(iii) Grantee will not engage in hedging transactions with regard to the Securities unless in compliance with the Securities Act;

-7-

(iv) The Company will refuse to register any transfer of the Securities not made in accordance with the provisions of Regulation S, pursuant to an effective registration statement under the Securities Act or pursuant to an available exemption from the registration requirements of the Securities Act; and

(v) The Company and others will rely upon the truth and accuracy of the acknowledgements, representations and agreements contained in this Option Agreement, and agrees that if any of such acknowledgements, representations and agreements are no longer accurate or have been breached, the Grantee shall promptly notify the Company.

(i) The Grantee is not a U.S. Person and the Grantee is not acquiring the Securities for the account or benefit of, directly or indirectly, any U.S. Person; and

(ii) The Grantee is outside the United States when receiving and executing this Option Agreement and is acquiring the Securities for investment only and not with a view to resale or distribution and, in particular, it has no intention to distribute either directly or indirectly any of the Securities in the United States or to U.S. Persons.

    (c)                 For purposes of this Option Agreement, “U.S. Person” means: (i) any natural person resident in the United States; (ii) any partnership or corporation organized or incorporated under the laws of the United States; (iii) any estate of which any executor or administrator is a U.S. Person; (iv) any trust of which any trustee is a U.S. Person; (v) any agency or branch of a foreign entity located in the United States; (vi) any non-discretionary account or similar account (other than an estate or trust) held by a dealer or other fiduciary for the benefit of or account of a U.S. Person; (vii) any discretionary account or similar account (other than an estate or trust) held by a dealer or other fiduciary organized, incorporated, or (if an individual) resident in the United States; and (viii) any partnership or corporation if (A) organized or incorporated under the laws of any non-U.S. jurisdiction and (B) formed by a U.S. Person principally for the purpose of investing in securities not registered under the
