3. Based on the foregoing, and subject to the qualifications expressed below, we are of the following opinions:

(a) ICM Taiwan Subsidiary is a company limited by shares duly incorporated and validly existing in good standing under the laws of ROC.

Page 4 of 9

(b) ICM Taiwan Branch is duly recognized as a branch office of a foreign company according to the laws of ROC.

(c) MagnaChip Taiwan is a limited company duly incorporated and validly existing in good standing under the laws of the ROC.

(d) Each of the Covered Entities has all requisite corporate or other statutory power and authority to execute, deliver and perform its obligations under the New Note Guarantees.

(e) The execution, delivery, and performance of each of the New Note Guarantees has been duly authorized by each of the Covered Entities to the extent they are a party thereto.

4. The opinions set out above are subject to the following qualifications and clarifications:

(a) Provisions in the Indentures, which provides for Covered Entities to pre-emptively waive certain rights explicitly prohibited by Article 739-1 of the ROC Civil Code, are invalid.

(i) Under Article 755 of the ROC Civil Code, if the creditors grant the Issuers an extension of time, unless Covered Entities specifically consents to that extension, Covered Entities are released from its obligations under the Indentures. Therefore, the language in Section 12.01(a)(2) stating that Covered Entities’ obligations are automatically extended in case of any extension of time of payment or renewal of any New Notes is invalid. In addition, the statement in Section 12.01(b) that Covered Entities obligation are unconditional and irrespective of any waiver or consent, and that Covered Entities’ obligation will not be discharged except by complete performance of the obligations contained in the Notes and the Indentures is also invalid.

(ii) Under Article 741 of the ROC Civil Code, the obligations of Covered Entities under the Indentures shall be no more than the principal debt. Therefore, the language in Section 12.01(b) stating that Covered

Page 5 of 9

Entities’ obligations are unconditional, irrespective of the validity, regularity or enforceability of the New Notes or Indenture, any waiver or consent by any Holders of the New Notes, and any other circumstance which might constitute a legal or equitable discharge or defense of the guarantor is invalid.

(iii) Under Article 742 of the ROC Civil Code, Covered Entities are entitled to take any defense that is open to the Issuers as a valid defense even when waived by the Issuers. Therefore, the statement in Section 12.01(b) stating that Covered Entities’ obligations are unconditional and irrespective of any waiver or consent and any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor, and that Covered Entities’ obligation will not be discharged except by complete performance of the obligations contained in the New Notes and the Indentures is invalid.

(iv) Under Article 744 of the ROC Civil Code, if the obligations under the Indentures are voidable by the Issuers, Covered Entities are entitled to refuse to perform their obligations under the Indentures. Therefore, the language in Section 12.01(b) stating that Covered Entities’ obligation are unconditional and irrespective of the validity, regularity and enforceability of the New Notes or the Indentures, and that Covered Entities’ obligation will not be discharged except by complete performance of the obligations contained in the New Notes and the Indentures is invalid.

(v) Under Article 749 of the ROC Civil Code, if either of Covered Entities makes payment to the creditor, it is entitled to subrogate the claim of the creditor against the Issuers to the extent of the payment made, as long as it is not exercised to the detriment of the creditor. Therefore, the language in Section 12.01(d) stating that Covered Entities agree that they will not be entitled to any right of subrogation until payment in full of all obligations guaranteed thereby is invalid to the extent it restrains the Covered Entities from exercising the right of subrogation

Page 6 of 9

for the portion they have paid prior to the payment in full of all obligations guaranteed thereby.

(vi) Under Article 751 of the Civil Code, if the creditors waive the rights in rem on which their claim are secured, Covered Entities are released from their obligations to the extent of the rights which have been waived. Therefore, the language in Section 12.01(b) stating that Covered Entities’ obligations are unconditional, irrespective of any waiver by any Holder of the New Notes is invalid.

(b) Any final and conclusive monetary judgment for a definite sum obtained against Covered Entities in the courts of the State of New York in respect to the obligations under the New Note Guarantees would be recognized and treated by the courts of the ROC as a cause of action in itself so that no retrial of the issues would be necessary provided that:

(i) The Courts of the State of New York rendering the judgment had subject matter jurisdiction in the matter under the laws of the ROC and the respective Covered Entities has either submitted to such jurisdiction or was duly served with process;

(ii) The content and procedures of the judgment was not contrary to public order (policy) and good morals of the ROC;

(iii) If the respective Covered Entities did not appear in the proceedings in such court and a judgment by default was entered, process has been served legally in connection with the respective Covered Entities in the jurisdiction of litigation or with the assistance of the judicial authorities of the ROC. Nothing herein should be read to mean that service on a contractually appointed service of process agent would be necessarily constitute legitimate service in jurisdiction for purposes of this item (iii); and

(iv) Judgments of the courts of the ROC would be enforceable in the jurisdiction of the courts of the State of New York on a reciprocal basis.

Page 7 of 9

(c) Any final, conclusive and un-appealable judgments on the merits against Covered Entities for a definite sum of money entered by a New York Court in any suit, action or proceeding arising out of or in connection with the New Note Guarantees to which Covered Entities are parties, provided that it meets the conditions indicated in 4 (b) (i)(ii)(iii) and (iv) above, normally would be enforced by way of summary proceedings based on the judgments, without re-examination of the matters adjudicated upon, by the court of ROC.

(d) When obligations are to be performed in a jurisdiction outside the ROC or construed under the laws other than those of the ROC, they may not be enforceable under the laws of the ROC to the extent that such performance would be contrary to public policy (order) or good moral under the laws of the ROC.

(e) Claims under the New Note Guarantees become barred under the laws relating to Statute of Limitations in the ROC or may be or become subject to defenses of offset or counterclaim.

(f) Rights and obligations may be limited by bankruptcy, insolvency, liquidation, arrangement and other similar laws of the ROC of general application affecting the rights of creditors.

5. This opinion is confined to and given on the basis of the laws of the ROC as they are in force at the date of this opinion. We are issuing this opinion purely from a legal perspective, without considering other aspects. We have made no investigation of, and express no opinion on, the laws of any other jurisdiction.

6. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of our name in the prospectus contained therein under the caption “Legal Matters.” In giving such consent we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.
